Abstract：
Musculoskeletal disorders, standing as the fifth leading cause of disability-adjusted life years globally, present significant challenges in orthopedics. Osteochondritis dissecans (OCD) and avascular necrosis (AVN) are distinct but closely related conditions within this spectrum, impacting patients\' quality of life with pain, limited mobility, and dysfunction. OCD, involving cartilage and bone detachment in joints, predominantly affects young athletes, but its exact etiology and optimal management remain subjects of ongoing research. Conversely, AVN, marked by bone tissue death due to compromised blood supply, is linked to systemic factors like corticosteroid use and traumatic injuries. Diagnosis for both conditions relies on radiography and magnetic resonance imaging. Conservative treatment for AVN includes the use of a cane or crutches, pharmacological therapy, or physical therapy. On the other hand, in OCD, the primary approach is activity/sports restriction. Surgical treatment options for AVN patients encompass core decompression, bone grafting, or, in the most advanced cases, total hip arthroplasty. OCD may be surgically treated through subchondral drilling or fixation of unstable lesions. Advanced cases of OCD involve cartilage salvage with resurfacing techniques. The presentation of differences between these conditions enhances our understanding, facilitating improved diagnosis and management strategies.
摘要：
肌肉骨骼疾病，作为全球残疾调整寿命年的第五大原因，提出了骨科的重大挑战。剥脱性骨软骨炎（OCD）和缺血性坏死（AVN）是不同的，但密切相关的条件在这个范围内，疼痛影响患者的生活质量，流动性有限，和功能障碍。强迫症,涉及关节软骨和骨脱离，主要影响年轻运动员，但其确切的病因和最佳管理仍是正在进行的研究的主题。相反，AVN,以血液供应受损导致的骨组织死亡为标志，与使用皮质类固醇和外伤等全身因素有关。两种情况的诊断都依赖于射线照相和磁共振成像。AVN的保守治疗包括使用拐杖或拐杖，药物治疗,或者物理治疗.另一方面,在强迫症中，主要方法是活动/运动限制。AVN患者的手术治疗选择包括核心减压，骨移植,或者，在最先进的情况下，全髋关节置换术。强迫症可以通过软骨下钻孔或不稳定病变的固定进行手术治疗。强迫症的晚期病例涉及使用表面置换技术进行软骨抢救。这些条件之间的差异的呈现增强了我们的理解，促进改进的诊断和管理策略。
