Avulsion of the tibial spine is functionally equivalent to rupture of the anterior cruciate ligament in an adolescent athlete. It therefore presents to general orthopaedists as well as a wide variety of orthopaedic subspecialty surgeons, including traumatology sports medicine, and pediatrics. Restoration of normal knee kinematics is dependent on anatomic reduction and fixation of the avulsed fragment. Because this injury is typically sustained by the skeletally immature patient, epiphyseal fixation is ideal to avoid physeal injury, which can lead to angular limb deformity. We present a case, the first report to our knowledge, of coronal plane deformity in a lower extremity after open reduction and internal fixation of a tibial spine avulsion fracture. A successful treatment plan using hemiepiphysiodesis and guided growth is used with 20-month follow-up to skeletal maturity.
胫骨棘撕脱骨折在功能上等同于青少年运动员前交叉韧带断裂。因此，它不仅会出现在普通骨科医生面前，也会出现在各种骨科亚专科医生面前，包括创伤、运动医学和儿科医生。恢复正常膝关节运动学依赖于撕脱碎片的解剖复位和固定。由于这种损伤通常发生在骨骼未成熟的患者身上，因此骺板固定是理想的选择，可以避免骺板损伤，从而导致肢体畸形。我们报告了一例胫骨棘撕脱骨折切开复位内固定术后下肢冠状面畸形的病例，据我们所知，这是首例报道。采用半骺阻滞和引导生长的成功治疗方案，随访至骨骼成熟共 20 个月。
