A study was conducted to determine what effect pinning in situ for slipped capital femoral epiphysis (SCFE) had on the timing of subsequent closure of the growth plate. Eighty-nine patients with a SCFE were reviewed. Twenty-six patients with a unilateral SCFE were treated with closed pinning in situ; no manipulative reductions were performed. The timing of physeal closure was assessed using postoperative radiographs of both pinned and non-pinned sides. The average time until physeal closure was 12.0 months for the pinned physis and 22.2 months for the non-pinned physis. In two cases, the physes closed simultaneously, and in no patient did the non-pinned physis close earlier than the pinned physis. The pinned physes closed an average of 10.2 months (range: 0 to 22) earlier than the unpinned physes. No difference was noted in the rates of closure with different types of internal fixation. This study supports the theory that pinning SCFE in situ causes early closure of the physis.
开展了一项研究，以确定原位固定治疗股骨头骨骺滑脱（SCFE）对后续生长板闭合时间有何影响。对89例SCFE患者进行了回顾性研究。26例单侧SCFE患者接受了原位闭合穿针固定治疗；未进行手法复位。通过对固定侧和未固定侧的术后X线片评估骨骺闭合时间。固定骨骺平均闭合时间为12.0个月，未固定骨骺为22.2个月。有2例患者双侧骨骺同时闭合，未出现未固定侧骨骺比固定侧骨骺闭合更早的情况。固定骨骺比未固定骨骺平均早闭合10.2个月（范围：0至22个月）。不同类型内固定的闭合率未发现差异。该研究支持原位固定SCFE会导致骨骺早期闭合这一理论。
