Outcomes of Hindfoot Arthrodesis Supplemented With Bioactive Glass and Bone Marrow Aspirate: A Retrospective Radiographic Study

Foot and ankle surgeons continue to explore bone graft alternatives that will be comparable to the reference standard of autologous bone. The purpose of the present study was to consider the outcomes of hindfoot arthrodesis supplemented with bioactive glass in patients at risk of delayed union and nonunion. We performed a retrospective radiographic review of 29 consecutive patients (48 joints) who had undergone arthrodesis of ≥1 joint of the hindfoot (ankle, subtalar, talonavicular, calcaneocuboid). All patients included in the present study had a minimum of 1 documented risk factor for osseous nonunion (history of previous nonunion, trauma, smoking, diabetes, Charcot arthropathy, obesity, age >65 years at surgery). The patients were followed up for a minimum of 24 weeks or until radiographic healing had been achieved. We found 12 (25.0%) nonunions across all 48 joints supplemented with bioactive glass. We found 4 (16.7%) nonunions in the subtalar joint, 1 (11.1%) in the calcaneocuboid joint, and 1 (11.1%) in the talonavicular joint. We found that hindfoot arthrodesis procedures supplemented with bioactive glass resulted in an incidence of union comparable to that with autograft and other bone graft substitutes.     

大段异体骨移植治疗骨干肿瘤

目的探讨大段异体骨移植治疗肢体长管状骨骨干肿瘤节段性切除后骨缺损的疗效。方法1995年7月至2006年7月应用此方法治疗骨原发良恶性肿瘤45例,资料完整者26例,胫骨13例,股骨7例,肱骨6例。按照Enneking分期,恶性肿瘤行边缘切除或广泛切除,部分行新辅助化疗。大段同种异体骨采用深低温冷冻保存,异体骨长度平均12．2cm,钢板螺丝钉或交锁髓内钉固定。结果随访14个月至13年,平均64．1个月。3例死亡,2例复发,2例感染。总骨端愈合率为66．7％,愈合时间平均15．7个月。截骨面位于松质骨者,愈合率为84．6％,愈合时间平均9．6个月。骨端不愈合者中,2个端为钢板螺丝钉固定（14．3％）,12个端为交锁髓内钉固定（40％）。异体骨骨折1例（4．2％）。术后功能评定采用MSTS评分,上肢21～28分,平均25．6分;下肢19～27分,平均24．8分。结论大段异体骨移植与宿主骨愈合后,在内固定的支持和协同作用下,有望长期甚至终身使用。在坚强内固定的支持下,较长时间的等待会增加骨端愈合率。不愈合患者通过接触端再植骨后,仍有较高的愈合机会。

Valgus extension overload: diagnosis and treatment

Valgus extension overload (VEO) is a constellation of symptoms and pathology commonly seen in the overhead athlete. Athletes in many sports may experience VEO and other common pathologies related to the high repetitive stresses generated by the overhead throwing motion. VEO is characterized by reproducible pain that is elicited by repeatedly forcing the elbow into terminal extension while applying a valgus stress to the elbow. Pain at the posteromedial tip of the olecranon process is pathognomonic of the condition. Olecranon stress fractures are rare, but can cause significant discomfort and, if unrecognized or untreated, can lead to significant pain and dysfunction. Both of these conditions are treated initially with rest from throwing, followed by gradual return to throwing through an interval throwing program. When conservative measures fail, minimally invasive or arthroscopic surgical procedures can be used to address the problem. Successful return to competitive overhead sports is expected at all levels of competition with these conditions.     

Ulnar nonunion after osteoclasis for rotational deformities of the forearm

PURPOSE: Osteoclasis, a minimally invasive technique to rotate the radius and ulna, is used commonly to correct forearm rotational deformities in children. The purpose of this investigation was to evaluate objectively osteotomy healing in patients treated with osteoclasis, with specific attention given to the risk for nonunion. METHODS: We identified 69 extremities in 65 children treated with osteoclasis and performed retrospective chart and radiographic reviews to evaluate the time to union of the radius and ulna and factors influencing healing. RESULTS: The average rotational correction was 90 degrees. Twenty-one ulnas had either delayed union or nonunion. Forty-eight of the forearms healed in less than 3 months. Factors correlated with a significantly decreased union rate included increased patient age, percutaneous technique, osteoclasis site in the proximal ulna, and primary diagnoses other than congenital radioulnar synostosis. Preoperative forearm position, magnitude of position correction, and treatment of the periosteum were not associated with changes in union rates. CONCLUSIONS: Forearm osteoclasis has a delayed union rate of 16%. Timely union of the ulna appears to be influenced by both patient-centered factors and surgical technique. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic, Level IV.
