This case report of a 5-year-old girl describes a severely comminuted fracture of the cervical and trochanteric areas of the left proximal femur which required open reduction and internal fixation for stable realignment. At 7 months follow-up, angulational deformity was recognized due to partial growth arrest leading to valgus tilt of the proximal femoral epiphysis. After persisting 1 year, gradual spontaneous improvement occurred leading to total realignment with a normally wide growth plate at 36 months following injury. It is hypothesized that the valgus deviation of the femoral head, by causing a medial shift of the weight bearing axis, led to relative unloading of the lateral margin of the growth plate. It is suggested that this mechanical element contributed to the spontaneous release of the epiphyseal tether.
本病例报告了一名5岁女童，其左股骨近端颈部和转子区发生严重粉碎性骨折，需要切开复位内固定以实现稳定的重新对线。在7个月的随访中，由于部分生长停滞导致股骨近端骨骺外翻倾斜，出现了角度畸形。持续1年后，逐渐出现自发改善，在受伤后36个月时实现了完全重新对线，生长板正常变宽。据推测，股骨头的外翻偏差通过导致负重轴内侧移位，导致生长板外侧边缘相对卸载。有人认为，这种机械因素促成了骨骺束缚的自发解除。
