Bisphosphonate therapy is not without its drawbacks, and has a variety of adverse effects ranging from short-term effects such as upper gastrointestinal upset to effects related to longer-term use such as osteonecrosis of the jaw, atrial fibrillation and suppression of bony turnover leading to atypical fractures13). Our website is not intended to be a substitute for professional medical advice, diagnosis, or treatment. Niemeyer P, Salzmann G, Steinwachs M, Sdkamp NP, Schmal H, Lenz P, Kstler W. Presence of subchondral bone marrow edema at the time of treatment represents a negative prognostic factor for early outcome after autologous chondrocyte implantation. Sibilska, Aleksandra, et al. 1. The timeline of our patients recovery is in keeping with those reported in the literature with regard to similar injuries: a case series of subchondral impaction fractures of the lateral femoral condyle reports that healing continues up to 3 years postinjury16). Koshino T (1982) The treatment of spontaneous osteonecrosis of the knee by high tibial osteotomy with and without bone-grafting or drilling of the lesion. Grade 3 to grade 4 chondral lesions of medial femoral condyle, trochlea, patella, grade 1 to grade 2 lesions of the lateral femoral condyle. Malocclusions. When refering to evidence in academic writing, you should always try to reference the primary (original) source.

Subchondral impaction fractures of the non-weight-bearing portion of the lateral femoral condyle. 2022 Dotdash Media, Inc. All rights reserved. Your femur, better known as your thighbone, extends from your hip to your knee. Stress fractures or insufficiency fractures are caused by too much relative load or stress on a bone over a period of time. Nat Biomed Eng. These similarities often lead to missed or delayed diagnosis which can often delay or change management. 2017 Aug;51(1):49-57. doi:10.1007/s13139-016-0443-8. Due to the acetabulum's close proximity to the sciatic nerve and major blood vessels in the thigh, a fracture of this bone can lead to nerve damage and internal bleeding. Subchondral fracture (black arrow) in the anterior-superior portion of the left femoral head. Generating an ePub file may take a long time, please be patient. It should be noted that, as demonstrated by our case, SIFK can occur in the lateral compartment and therefore must always be considered as a potential cause for lateral knee pain. A subchondral insufficiency fracture (SIF) of the femoral head is a recently proposed concept, which needs to be differentiated from osteonecrosis. If osteoporosis goes untreated, fractures can occur spontaneously without injury (ie insufficiency or fragility fractures). 6. Meniscus root or radial tears are frequently associated with subchondral insufficiency fractures because this type of lesion abruptly increases the load on the subchondral bone Shanb AA, Youssef EF. This article aims to present this unusual case of lateral compartment SIFK and summarise the literature on this uncommon condition. The underlying cause of these subchondral fractures is also a topic of controversy. J Bone Jt Surg Am 64:4758, 7. Other lesions on the lateral femoral condyle, medial tibial plateau and patella have also been described. 18. Your doctor will try to identify the cause of your fracture. Differentiating subchondral insufficiency fracture from osteonecrosis may help avoid unnecessary total hip arthroplasty Effects of Gastrocnemius Recession on Ankle Motion, Strength, and Functional . A reinforcing member that stabilizes the insufficiency fracture is then implanted via the access path. However, it should be noted that systemically decreased BMD may not necessarily reflect local BMD of the knee, which may play a role in the development of SIFK. Knee osteoarthritis (OA) is a chronic degenerative disease that leads to loss of articular cartilage, whereas subchondral insufficiency fractures of the knee is an acute disease of the subarticular bone. the display of certain parts of an article in other eReaders. Injury. Narrowed joint space was present in 99.5%, osteophytes in 98.1% and subchondral sclerosis in 88.3% of all radiographs. Stage 2 has the presence of a radiolucent subchondral oval lesion, flattening of the convexity of the condyle or both. More recent studies have shown the etiology most likely attributed to a subchondral insufficiency fracture and proposals have been made to change the name to subchondral insufficiency fracture of the knee (SIFK). . Subchondral insufficiency fracture of the knee (SIFK) is a potentially devastating disorder that may progress rapidly to osteoarthritis with articular surface collapse. showed excellent results over a period of one year using a combined therapy with NSAIDs and bisphosphonates in a group of ten patients, mainly with stage 1 SONK [17]. The fear of falling and injuring yourself can have a negative impact on your physical and psychological health when you have osteoporosis. Subchondral insufficiency fracture in a 69-year-old woman who presented with acutely worsening knee pain without known trauma. The femoral neck bones and the acetabular bones are the sites of most hip fractures. The second area of breakage is the sacrum, These fragility pelvic fractures can be painful and are treated with rest, minimizing weight bearing with a. Fractures here usually require surgery to stabilize the bone with screws, plates, or rods. On physical examination, her left knee exhibited a grade one effusion with tenderness on palpation of the lateral joint line. Kraenzlin ME, Graf C, Meier C, Kraenzlin C, Friedrich NF (2010) Possible beneficial effect of bisphosphonates in osteonecrosis of the knee. Hospital for Special Surgery. The acetabulum is the socket of the hip joint that connects to the femoral head. Factors predisposing to insufficiency fractures may include meniscal tears or meniscectomy, which can alter the native biomechanics and increase contact pressures and stress concentration on weight bearing areas [4]. Pathology. A 65 year old active female is referred to physical therapy by his primary care provider for insidious onset left medial knee pain. Subchondral insufficiency fractures (SIF) are . STIR images show that the high intensity lesion (c) is smaller after 10 weeks of therapy and (d) has almost disappeared after 4 months of therapy. xray *Phalen test (60secs) - positive if pain/paresthesias in at least 1 fig. 33. On visual inspection, the left leg appeared to be in more valgus alignment than the right. It is characterized by a linear trace with low serpiginous signal parallel to the articular surface in the coronal T1 (a), T2 with fat saturation in the coronal (b) and sagittal (c) images. Some authors consider SIFK and SONK to be synonymous or equivalent pathological processes2,5), whilst others believe SIFK to be an inciting event for SONK to occur. Stage 3 shows an expanded radiolucent area surrounded by a sclerotic halo and Stage 4 has apparent secondary OA changes [6]. 34. These are typically located in the She had no relevant medical history of note and family history was negative. The patient was referred for a second course of bisphosphonate infusion treatment, and commenced this treatment at 12 months after her first presentation. 2016 Mar;47(3):707-710. doi:10.1016/j.injury.2016.01.027, Haberal B, imek EK, Iik M. Incidence and mortality of osteoporotic sacral insufficiency fractures: a retrospective single-centre study. Instead of BMD, Nelson et al.7) argue that SIFK may be instead related to injuries associated with weight bearing abnormalities which occur in the setting of osteoarthritis, with their case series demonstrating a close association between SIFK and meniscal extrusion or injury. MRI was repeated and revealed a further reduction in her bone marrow oedema in the lateral femoral condyle. Concurrent meniscal tears are common and can be diagnosed on MRI [10]. Spontaneous osteonecrosis of the knee: the result of subchondral insufficiency fracture. Little DG, Peat RA, Mcevoy A, Williams PR, Smith EJ, Baldock PA. Zoledronic acid treatment results in retention of femoral head structure after traumatic osteonecrosis in young Wistar rats. Additional magnetic resonance imaging (MRI) revealed a subchondral insufficiency fracture on the extensor surface of the lateral femoral condyle and the presence of a large amount of bone marrow oedema measuring 2.4 cm in the anteroposterior plane and 2.1 cm transversely (Fig. Kennel KA, Drake MT. Medial tibial plateau subchondral fracture. Arthritis Rheum. And they also cause specific effects, depending on the location and size of the fracture. Knee Surg Sports Traumatol Arthrosc 25, 477484 (2017). SIF is a rare disease that causes acute pain in the hip joint. Due to this close relationship, SIFK and SONK are sometimes used interchangeably as terms, although some authors have suggested SONK should be renamed as SIFK2,3). 2018 Jan;2(1):62-71. doi:10.1038/s41551-017-0183-9. J Turk Spinal Surg. This occurred in association with either meniscal tears or meniscectomy. The pain developed 50 weeks into a rigorous year-long marathon running campaign during which she completed 52 marathons in 52 weeks. The diagnosis of SIFK should be considered in any patient presenting with new-onset knee pain, particularly in active female patients with either local or systemically decreased BMD. Objective: Subchondral insufficiency fracture of the femoral head (SIF) is a recently recognised cause of acute onset arthritis mostly in older women, which previously had been commonly considered either as osteonecrosis or osteoarthritis. A subchondral fracture refers to a fracture subjacent to the cortex and the subchondral bone plate, without cortical contour abnormality or disruption.

Osteochondritis dissecans (OCD) is a term for a distinct clinical-pathologic entity: a pathologic condition that affects subchondral bone formation and may result in an unstable subchondral fragment, disruption of adjacent articular cartilage, and possible separation of the fragment. As many as two-thirds of pelvic ring insufficiency fractures in people with osteoporosis happen without any known traumatic event. This paper describes an unusual case of SIFK in the lateral femoral condyle of a female ultra-marathon athlete who was successfully managed with non-operative treatment. Effect of ibandronate on spontaneous osteonecrosis of the knee: a randomized, double-blind, placebo-controlled trial. The most common area for this type of fracture is the pelvis.

In addition to asking about your pain and conducting a physical exam, your doctor may need to order imaging tests to diagnose a fracture. These findings are consistent with our case: our patient had an overall T-score of 0.7 with local osteopenia identified at the spine (1.2) and the neck of femur (1.1). In at least 80 percent of cases, the pubic ramus fractures in two places at once. POSTOPERATIVE DIAGNOSIS: Medial meniscus tear of the posterior horn, right knee. They will want to know where your pain is located, whether it is dull or stabbing, and what sorts of movements make it worse. You may experience the following if you have a fracture in your acetabular bone, sacral bone, femoral neck, or elsewhere in your hip: Hip fractures can also result in life-threatening complications due to the risk of injury to nearby blood vessels.

It usually affects the inside of the knee or the medial compartment which bears more stress and may involve the medial condyle of the femur. Figure 1. (b) A subchondral insufficiency fracture (SIF) is evident at the posterolateral aspect of the femoral head in the oblique three-dimensional CT view. Grade 1 involves less than 33% of the subregional volume, grade 2 involves 3366% of subregional volume, and grade 3 involves more than 66% of the volume [7]. There is slightly limited ROM due to a small effusion. It is proposed that the primary etiology for SIFK is a subchondral insufficiency fracture resulting in localized osteonecrosis based on both histopathologic analysis and marked similarities to subchondral insufficiency fractures of the femoral head[2]. Subchondral insufficiency fracture of the femoral head treated with core decompression and bone void filler support. These bones can become especially weak, thin, and frail due to osteoporosis, vitamin D deficiency, or aging. Complaints include progressive knee pain that is worse with weight bearing activities and worse at night. Transient osteoporosis of the knee can present in a similar manner but more commonly affects the hip and would not have any sclerotic rim lesions over the medial femoral condyle but would have diffuse bone edema on MRI and decreased bone density on a DEXA scan. SIFK/SONK lesions are more commonly described in the weight bearing medial articulation due to the associated repetitive loading4). Nelson FR, Craig J, Francois H, Azuh O, Oyetakin-White P, King B. Subchondral insufficiency fractures and spontaneous osteonecrosis of the knee may not be related to osteoporosis. The pain typically gets worse with weight bearing and at night. 1). It is most frequently found in elderly women with osteoporosis. 5,10,19,31,40,53,55,58,61-63,66 Subchondral fractures of the femoral head also were reported to occur as a fatigue-type stress fracture in healthy young military .

Subchondral insufficiency fracture of the femoral head (SIF) 4 hips: Rheumatoid arthritis of the hip: 1 hip: Surgical Techniques. With others, you may be encouraged to place as much weight on the injured areas as you can tolerate, taking rests as needed. SIFFH is often mistaken for osteonecrosis given similar clinical and radiographic features. Subchondral fractures were defined as T1-T2 hypointense signal intensity changes, usually in the form of a line paralleling the articular surface. Sitemap. already built in. with 15 patients reported an 87% success rate with joint preserving surgery that included core decompression, arthroscopy and autologous graft transfer [14]. In general, non-operative treatment regimes are centred around non- or partial weight bearing with an aim to optimise bone density via administration of bisphosphonate to prevent further subchondral collapse9). 5. Although subchondral impaction fractures have already been reported in the non-weight-bearing portion of the lateral femoral condyle, this study reveals the presence of an intra-articular impaction fracture of the postero-superior region of the non-weight-bearing portion of the medial femoral condyle recognized in 5 of a group of . Duany NG, Zywiel MG, McGrath MS, Siddiqui JA, Jones LC, Bonutti PM, Mont MA. X-rays of the knee showed preserved joint space with no definitive lesions or signs of osteoarthritis. The effects of a sacral fracture can increase the risk of additional falls, and sometimes it can cause a person to become bedridden. By Jonathan Cluett, MD The term insufficiency fracture implies bone that is inadequate to sustain a force or repeated forces that would be within the physiologic limits of normal bone. The natural history of spontaneous osteonecrosis of the medial tibial plateau. Doctors use these maneuvers to check how your hip moves and whether or not there is swelling. Patel H, Kamath AF. You may notice problems with Because they often aren't caused by serious trauma, many people can experience pain without remembering any specific traumatic event or fall. Smaller lesions or lower stage lesions typically respond to non-operative management and more advanced lesions may eventually require knee arthroplasty. Conclusion: Since this study, subchondral insufficiency fracture has been increasingly studied, including the identification of risk factors and associated lesions . SIFK typically presents with acute knee pain localized to the area of the subchondral fracture [ 1, 2 ]. Osteoarthritis of the knee would likely have changes present on the radiograph and no sclerotic lesion would be present. A subchondral insufficiency fracture is a type of stress fracture that occurs when bone underlying the cartilage in a joint is unable to bear stresses normally subjected to the joint. You may have developed subchondral cysts along with the fluid buildup. Whilst this effect has been demonstrated in animal studies10,11), a randomized controlled trial demonstrated no significant difference between ibandronate treatment and placebo in SONK12). Subchondral insufficiency fracture (SIF) of the femoral head has recently been recognized as a cause of the femoral head collapse, resulting in the degeneration of the hip joint, which is known to occur in association with osteonecrosis of the femoral head (ONFH) [1,2,3].Although the precise prevalence of SIF is unknown, previous studies with histopathological re-evaluation showed that SIF was . Characterization and pathological characteristics of spontaneous osteonecrosis of the knee. In conclusion, spontaneous osteonecrosis of the knee (SONK) typically affects individuals that are age 55 or older and presents with sudden non traumatic unilateral knee pain. An insufficiency fracture is a type of stress fracture that can occur due to minor pressure in a bone that is weakened. Fractures in each of these areas can cause similar symptoms, and they can also result in potentially life-threatening complications.

Clinical resolution of symptoms in small lesions was reported to have a mean of 4.8 months with radiographic resolution at a mean of 8 months. This type of bone cyst is caused by osteoarthritis. Jonathan Cluett, MD, is board-certified in orthopedic surgery. Your doctor will likely order imaging tests. In our case, our patient was managed conservatively with bisphosphonate therapy and was free of everyday symptoms at 18 months and at 30 months had regained full athletic function, reinforcing the notion that bisphosphonates are effective in the treatment of SIFK. Depending on those test results, you may need to start taking calcium and vitamin D supplements to strengthen your bones. We believe that the development of SIFK may be related to both a degree of local osteopenia, as well as degenerative processes, whether macro- or microscopic.

One major difference between pelvic fractures and hip fractures is that gentle leg motions are significantly more painful when you have a hip fracture compared to a pelvic fracture. [Updated 2020 Jul 10]. See specific links above and or links to osteoporosis management. Forgot your username? Conservative treatment is first-line in the management of SIFK, although surgery may be indicated for non-remitting or mechanical symptoms. 2). It should be suspected in . Patients with stage 3 and 4 or with lesions greater than 5 cm squared will normally undergo high tibial osteotomy (HTO), a unilateral knee arthroplasty (UKA) or total knee arthroplasty (TKA). They can often be spotted on an MRI. Pathologic Fractures [Figure 4-30-3] 5-10% of all patients with mets 50% or more cortex gone - 2/3 will develop pathologic fracture 61 year old woman with breast Less than 50% cortex gone - 1/5 will develop pathologic fracture cancer, focal depression of L2 Any lesion in femoral neck superior endplate is indicative of Avulsion of lesser . They are most commonly associated with osteopenic or osteoporotic bone and the female athlete triad in young athletes. No algorithm or definite consensus exists for treatment, but most recommendations are based or guided on the extent or severity of the disease or lesion. At the latest follow-up at 30 months, the patient reported no further knee pain and a successful return to ultra-marathon running. Meier C, Kraenzlin C, Friederich NF, Wischer T, Grize L, Meier CR, Kraenzlin ME. Clinically, SIF has generally been observed in. By definition, secondary osteonecrosis of the knee occurs secondary to an insult. Subchondral insufficiency fracture of the knee (SIF/SIFK) are stress fractures in the femoral condyles or tibial plateau that occur in the absence of acute trauma, typically affecting older adults. May 2018, 16. A subchondral insufficiency fracture is a type of stress fracture that occurs when bone underlying the cartilage in a joint is unable to bear stresses normally subjected to the joint. Subchondral Insufficiency Fracture in the Lateral Compartment of the Knee in a 64-Year-Old Marathon Runner. It is often underdiagnosed or misdiagnosed as . MRI follow-up at this point revealed some improvement in both the volume and intensity of the bone marrow oedema in the lateral femoral condyle (Fig. Like other insufficiency fractures, acetabular fractures commonly occur after a low-impact fall with osteoporosis. Subchondral insufficiency fractures (SIF) are a type of stress fracture which occurs below the cartilage on the weight bearing surface of a bone. 1Faculty of Medicine, University of Sydney, Sydney, Tumors. If no worsening changes occurred with follow up radiographs at 3 months, the patient graduated into full weight bearing. Risk factors for progression include lesion size on radiographs, anatomical angle (femorotibial angle) on sagittal MRI and depth on MRI. If you have osteoarthritis, bone marrow edema may be a sign that your condition has gotten worse. 2016;4(3):264-268. 2020 Jan;31(1):36-40. doi:10.4274/jtss.galenos.2020.62. If you are up to it, they may ask you to walk across the room to assess your gait (walking pattern). Subchondral insufficiency fractures of the femoral head (SIFFH) are a cause of femoral head collapse leading to degenerative hip disease. Animal studies have demonstrated that bisphosphonates prevent early resorption of spontaneously necrotic bone, thus preventing structural failure and therefore progression to SIFK. Subchondral insufficiency fracture usually occurs in association with degenerative joint lesions, including involvement of the meniscus and/or cartilage (2,4-8) . Read more, Physiopedia 2022 | Physiopedia is a registered charity in the UK, no. https://doi.org/10.1007/s00167-015-3839-6. A fracture in your pubic ramus bones, sacral bone, or elsewhere in your pelvis can cause the following symptoms: Pelvic fractures can result in life-threatening complications, especially when there are multiple fractures involved. Subchondral insufficiency fracture of the knee (SIF/SIFK) are stress fractures in the femoral condyles or tibial plateau that occur in the absence of acute trauma, typically affecting older adults. A subchondral insufficiency fracture (SIF) of the femoral head is a recently proposed concept, which needs to be differentiated from osteonecrosis. The use of alendronate to prevent early collapse of the femoral head in patients with nontraumatic osteonecrosis: a randomized clinical study. Make your home safer by clearing pathways, removing clutter that you could trip over, placing a rubber bathmat or nonslip seat in the shower, and moving more slowly through your home. The anteroposterior knee radiograph can be used to determine the stage of SIFK progression in the medial femoral condyle, which was classified into four stages. Nonoperative management is an option for smaller lesions (less than 3.5 cm) or stage 1 or 2 lesions [16]. Physical examination will usually have localized tenderness to palpation over the affected area or lesion and is the most common finding [8]. Most providers will start with a timeframe of 6-12 weeks of protected weightbearing. Neither a subchondral fracture line nor a bone marrow edema pattern is detected. Lesions of the medial femoral condyle represent up to 94 percent of cases [8]. Operative management may be utilized depending on size or depth of the lesion or clinical course and is usually reserved for cases with evidence of subchondral collapse (stage 3-4). The timeframe for the protected weight bearing is not supported by any randomized trials. Diagnosis is often missed and attributed to early osteoarthritis symptoms and providers must have this on their radar when evaluation knee pain in patients greater than 55. J Family Community Med. Stages were described earlier for stages 3 and 4. Both present with acute knee pain in the absence of trauma, which manifests radiologically as bone marrow oedema surrounding a necrotic area if progression to SONK has occurred. Subchondral insufficiency fractures are non-traumatic fractures that occur immediately below the cartilage of a joint. However, these methods are sometimes not enough to help heal the hip bone. Subchondral insufficiency fractures predominantly involve the medial compartment of the knee and commonly present with medial meniscal root and radial tears. https://pubmed.ncbi.nlm.nih.gov/29958686/, https://www.physio-pedia.com/index.php?title=Insufficiency_Fracture&oldid=257344, They should not be confused withfatigue fractureswhich are due to abnormal stresses on normal bone, or withpathological fractures, the result of diseased, weakened bone due to focal pathology such as tumours (both, Insufficiency fractures can occur throughout the skeleton but are common in the tibia, femoral head and neck, sacrum, pelvis, and feet. Our case did not support this notionthe SIFK to the lateral compartment was not accompanied by any concurrent degenerative changes. Finally, if pain is non-responsive to conservative measures, or if mechanical symptoms arise due to loose body formation, surgical management may be warranted. MRI findings in the subchondral bone marrow: a discussion of conditions including transient osteoporosis, transient bone marrow edema syndrome, SONK, and shifting bone marrow edema of the knee. Medial tibial subchondral fracture, right knee. Regardless of your age and whether or not you have known risk factors for an insufficiency fracture, it's never too late to start strengthening and protecting your bones with these steps: These steps are especially important for women who have a family history of bone loss.

If you can recall a time when you fell, bumped into something, or landed too hard on yourselfno matter how insignificant the event waslet your doctor know. Aortic Insufficiency 12.9.2.2. Pain typically occurs with weightbearing, at rest and seems to be worse at night. Given the severity and restriction of life conferred by the symptoms, surgical management was discussed with the patient, including offloading, distal femoral osteotomy, resurfacing procedures, and partial joint replacement. Depasquale R, Fotiadou A, Kumar DS, Lalam R, Tins B, Tyrrell PN, Singh J, Cassar-Pullicino VN. Treatment algorithm used in [17] based on Koshing Staging and BML Grade, Table 2. A posterolateral approach without a navigation system was used in all patients, and we routinely preserved the pyriform muscle. These bones can become especially weak, thin, and frail due to osteoporosis, vitamin D deficiency, or aging. Ann Transl Med. Surgical interventions described in the literature include unicompartmental knee arthroplasty14) as well as joint preserving procedures such as autologous osteochondral grafting or resurfacing procedures15). Sports Medicine Review is a website dedicated to all things primary care sports medicine. Although the entity is most frequently encountered at the weightbearing surface of the medial femoral condyle, the lateral femoral condyle or the tibia may also be involved (3a,4a). Plain radiograph of the knee demonstrating subchondral lucency within the femoral condyle but otherwise normal appearance. There are certain risk factors that have been found that include female sex, cartilage degeneration, low bone mineral density and medial meniscus posterior root tears [3]. If your doctor determines that you have osteoporosis, you should begin making lifestyle changes right away. There was a questionable sclerotic rim lesion over the medial femoral condyle. Some reported cases of SIF of the femoral head have progressed to collapse, necessitating surgery, whereas others have resolved with conservative treatment [1-3, 6]. The bones are too "fragile" or "insufficient" to support one's weight for simple daily activities such as standing or walking. Link to this slide . 2013 Aug;143(1):1-7. doi:10.4414/smw.2013.13859, Rommens PM, Hopf JC, Herteleer M, Devlieger B, Hofmann A, Wagner D. Isolated pubic ramus fractures are serious adverse events for elderly persons: an observational study on 138 patients with fragility fractures of the pelvis type I (FFP type I). Centers for Disease Control and Prevention. Imaging begins with AP, lateral and oblique radiographs of the knee. Axial (top) and sagittal (bottom) magnetic resonance imaging scans demonstrating the progression of the patients subchondral insufficiency fracture at presentation (A, B) and at 6 months (C, D) and 30 months of follow-up (E, F). Insufficiency fractures can sometimes be misdiagnosed or underdiagnosed. Journal of Orthopaedic Surgery. Education can be key to prevention of these fractures. At this point, it was advised that impact exercises should continue to be avoided. The sacrum is a triangle-shaped bone made of five disks (vertebrae) that is located at the bottom of the lower (lumbar) spine. Subchondral insufficiency fractures of the knee (SIFK) are painful, nontraumatic fractures that occur predominantly in the medial femoral condyle of postmenopausal osteoporotic women in their fifth and sixth decades of life. Grading can be done with plain radiographs or MRI and staging will likely guide the management of each case. Taking care of the injury as soon as possible improves your chances for a full recovery. 11.4.1. Mostly small studies exist for bisphosphonates with both IV and oral bisphosphonates.
