본 교실에서는 주관절에 발생한 후외측방 회전 불안정성에 의한 재발성 탈구 환자에 대해 Nestor 술식을 이용한 외측 척측부인대 재건을 1례 치 험하였다. 주관절의 재발성 탈구의 치료에 있어서는 병인중 가장 많은 후외측방 회전 불안정성에 대한 이해가 필요하며 그에 따른 외측 척측부인대 재건등의 수술적 수기와 술후 적절한 재활 치료가 치료결과에 큰 영향을 미치게 된다.

재발성 주관절 후외방성 회전 불안정성은 주관절의 아탈구, 탈구 또는 골절 등 외상, 수술 또는 외반주 변형이후 과부하등으로 인해 외측 척측 측부 인대 손상의 결과로서 발생하고, 주관절 pivot shift 검사는 주란절에 외반력, 종축 압박력과 회외전 모멘트로 후외방 아탈구를 유발하는 검사로서 주관절 후외방성 불안정성에 있어 가장 예민한 검사로 알려져 있다.

Background: Posterolateral rotatory instability (PLRI) is a common mechanism of recurrent elbow instability. While the essential lesion is a deficiency in the lateral ulnar collateral ligament (LUCL), there are often associated concomitant bony lesions, such as an Osborne-Cotterill lesions (posterior capitellar fractures) and marginal radial head fractures, that compromise stability. Currently, there is no standard treatment for posterior capitellar deficiency associated with recurrent PLRI. Methods: We conducted a retrospective review of five patients with recurrent PLRI of the elbow associated with a posterior capitellar impaction fracture engaging with the radial head during normal range of motion. The patients were treated surgically with LUCL reconstruction or repair and off-label reconstruction of the capitellar joint surface using a small metal prosthesis designed for metatarsal head resurfacing (HemiCAP toe classic). Results: Five patients (three adolescent males, two adult females) were treated between 2007 and 2018. At a median follow-up of 5 years, all patients had complete relief of their symptomatic instability. No patients had pain at rest, but two patients had mild pain (visual analog scale 1-3) during physical activity. Three patients rated their elbow as normal, one as almost normal, and one as greatly improved. On short-term radiographic follow-up there were no signs of implant loosening. None of the patients needed reoperation. Conclusions: Recurrent PLRI of the elbow associated with an engaging posterior capitellar lesion can be treated successfully by LUCL reconstruction and repair and filling of the capitellar defect with a metal prosthesis. This treatment option has excellent clinical results in the short-medium term. Level of evidence: IV.
