摘要

病例：一名 4 岁男孩的肱骨外侧髁骨折非常罕见，骨折从肱骨外侧穿过髁软骨，一直延伸到髁内侧，开放复位内固定术（ORIF）后出现了骨不连。手术后五个月，肘关节的主动屈曲度被限制在50°。磁共振成像（MRI）显示，肘关节前软骨出现阶梯状脱落，导致屈曲受限。经过 5 年的保守观察，肘关节屈曲度改善至 135°，核磁共振成像显示阶梯状脱位已消失：本病例表明，儿童患者在肘关节骨折错位后有可能恢复活动范围。

Natural Recovery of Very Limited Elbow Flexion After Rare Lateral Humeral Condylar Fracture in a 4-Year-Old Boy: A Case Report.

Case: A 4-year-old boy developed malunion after open reduction and internal fixation (ORIF) of a rare lateral condylar humeral fracture running from the lateral humerus, through the trochlear cartilage, to the medial trochlea. Five months after ORIF, the active elbow flexion was limited to 50°. Magnetic resonance imaging (MRI) showed a step-off of the anterior trochlear cartilage, causing the limited flexion. After conservative observation for 5 years, the flexion improved to 135° and MRI showed that the step-off had disappeared.

Conclusion: This case indicates that it is possible for pediatric patients to recover their range of motion following malunion of an elbow fracture.

期刊介绍： JBJS Case Connector helps improve patient care by providing the medical community with a journal that harnesses technology to provide information tools for discovery and reporting of unusual musculoskeletal problems, findings, treatment, and outcomes. Co-edited by Thomas W. Bauer, MD, PhD, and Ronald W. Lindsey, MD, JBJS Case Connector assists orthopaedic surgeons in the search for precedents, connections, and trends in their efforts to improve patient care. Using this unique journal, surgeons can find the commonalities between cases, benefit from the experience of their peers, and filter case information by many important variables in order to provide the best possible care for orthopaedic patients. This cross-referenced online journal includes thousands of orthopaedic case reports. It compiles symptoms, conditions, and demographic details to empower surgeons to find cases similar to theirs. Surgeons can mine the database to reveal emerging trends and identify patterns, distinguishing between truly rare cases and repeated, related single instances of a larger problem. The JBJS Case Connector Image Quiz feature provides interactive quizzes based on images from content published by JBJS and includes a discussion area for further exploration of ideas and concepts. The JBJS Image Quiz app for iPad and iPhone is available in the App Store. Contributions to JBJS Case Connector are welcomed from anywhere in the world and are considered on their merits. Articles must be written in English and should be submitted as outlined in the Instructions to Authors. All authors must abide by the JBJS ethics policies and all submissions to JBJS Case Connector are covered by the JBJS embargo policy.
