Abstract

BACKGROUND

The management of unstable slipped capital femoral epiphysis (SCFE) is controversial. A high incidence of avascular necrosis (AVN) has been reported after unstable SCFE.

METHODS

Twenty-eight consecutive patients with thirty unstable SCFE underwent urgent reduction and fixation with two 6.5-mm cannulated screws. Positional reduction was performed in 25 cases. Arthrotomy was performed percutaneously in 16 cases and as part of an open capsulotomy in 5 cases.

RESULTS

Slip severity was mild in 13 patients, moderate in 9, and severe in 8. At mean duration of follow-up of 5.5 years (range: 2.0 to 11.2), 4 patients reported groin pain, and 8 patients reported a limp. Four patients developed AVN. One patient experienced slip progression and no patient developed chondrolysis.

CONCLUSIONS

Treatment of unstable SCFE with urgent positional reduction with accompanying arthrotomy and fixation through 2 cannulated screws resulted in a low incidence of slip progression and AVN.

LEVEL OF EVIDENCE

Therapeutic study, level 4 (case series, no or historical control group).

摘要

背景

不稳定型股骨头骨骺滑脱(SCFE)的治疗存在争议。据报道,不稳定型SCFE后股骨头缺血性坏死(AVN)的发生率较高。

方法

连续28例患者共30例不稳定型SCFE接受了紧急复位并用两枚6.5毫米空心螺钉固定。25例行闭合复位。16例经皮进行关节切开,5例作为开放关节囊切开术的一部分进行。

结果

13例患者滑脱程度为轻度,9例为中度,8例为重度。平均随访时间为5.5年(范围:2.0至11.2年),4例患者报告腹股沟疼痛,8例患者报告跛行。4例发生AVN。1例出现滑脱进展,无患者发生关节溶解。

结论

对不稳定型SCFE进行紧急闭合复位并伴有关节切开,通过2枚空心螺钉固定,导致滑脱进展和AVN的发生率较低。

证据水平
