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.

목적: 외상으로 인한 슬관절 외측 및 후외측 불안정성을 보이는 환자에게 있어 동시 외측 보강술 및 슬와근 건고정술을 시행하는 방법으로 그 치료결과를 보고하고자 한다. 대상 및 방법: 1996년 7월부터 2003년 7월까지 슬관절 외측 및 후외측 불안정성으로 진단 받고 외측보강술 및 슬와근 건고정술 후 1년 이상 추시 관찰이 가능했던 21예를 대상으로 하였다. 남자가 15예, 여자가 6예이었으며 평균연령은 38.5세였다. 손상 후 수술까지의 평균기간은 6.8개월이었다. 슬관절 외측 및 후외측 불안정성의 치료에 있어 본원에서는 대퇴부 외상과에서, 3예에서는 아킬레스 동종건 이식을 시행하였고 18예에서 내측부 인대용 ABC인조인대(Active Bioprosthetic Composite Polyester Ligament, Surgicraft, U. K. )를 이용하여 외측 측부인대의 보강 및 슬와근 건고정술을 동시에 시행하였다 결과: 최종 추시상 슬관절 90도 굴곡 후방 부하 방사선 촬영상 후방 전위의 정도는 건측에 비해 평균 5.6 mm에서 2.5 mm로 개선되었다. 슬관절 30도 굴곡상태의 내반 검사는 전위정도가 건측에 비해 수술 전 평균 8.2 mm의증가소견을 보였으나, 수술 후에는 평균 2 mm의 증가소견만을 보였다. Lysholm score는 수술 전 평균 52.5점에서 수술 후 평균 86.7점으로 34.2점 증가하였고 자가건 이식과 ABC 인조인대를 사용한 군에서 결과는 유의한 차이점은 없었다. 결론: 슬관절의 외측 및 후외측 불안전성에 대한 외측 보강술 및 슬와건 건고정술은 수기 및 수술 후 치료방법이간단하며, 임상적, 방사선학적 평가 결과로 미루어 보아 효과적인 치료 방법 중의 하나로 판단된다.

Generally, the posterolateral approach had been recommended in case of extraforaminal disc herniation or lateral stenosis but it has been speculated that this procedure may be feasible to posterolateral disc herniation at the high lumbar levels of the L1-L2 interspace. Topographically, a posterolateral approach should be able to access anteromedial side of the spinal canal without the risk of the bony instability and damage to the neural structures. During the past one year period, three patients with high lumbar discs at the L1-L2 level were treated by the modified posterolateral approach. This article describeds the details of this approach with pertinent literature review.

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.

The trained examiner can gain considerable information from visual inspections of the elbow joint, Because much of the joint is subcutaneous, any appreciable alteration in the skeletal anatomy often is detectable. Gross soft tissue swelling or muscle atrophy is also early observed. Inspection and palpation of the medial and lateral epicondyles and the tip of the otecranon from an equilateral triangle with the elbow is flexed. Normally, the arc of flexion extension, although variable, ranges from about O to 140 degrees plus or minus 10 degrees. The posterolateral rotatory instability(PLRI) of the elbow is most common pattern of elbow instability. The lateral collateral ligament complex also includes a narrow but stout band of ligamentous tissue blending with the distal and proterior fibers of the capsule to insert distally on the crista supinatoris of the ulna. This is the lateral ulnar collateral ligament(LUCL). A clinical elbow pivot shift test confirms the PLRI. There are also two active apprehension signs.

Objective: The purpose of this study was to investigate whether dancers with chronic ankle instability (CAI) exhibit different characteristics in dynamic postural control ability and ankle joint laxity compared to dancers without CAI and non-dancers with CAI. Method: Twelve dancers with CAI, 14 dancers without CAI, and 12 non-dancers with CAI participated in the study. Dynamic balance was evaluated using the Star Excursion Balance Test (SEBT) and the single-leg hop balance. The laxity of the ankle joint was evaluated through the anterior drawer test and the talar tilt test. SEBT measured maximum reach distances in anterior, posteromedial, and posterolateral directions. Single-leg hop assessed center of pressure (COP) and time-to-boundary (TTB) outcomes. One-way ANOVA and Chi-square tests were performed to compare the outcome variables among the three groups. Results: Dancers with CAI demonstrated greater reach distance in the posterolateral direction compared to non-dancers with CAI during SEBT (p=.014). Secondly, dancers without CAI showed greater reach distance in the posterolateral (p<.001) and posteromedial (p=.001) directions during SEBT compared to non-dancers with CAI. Additionally, dancers without CAI exhibited better postural control with higher TTB AP mean of minima (p=.003) and TTB AP standard deviation of minima (p=.012) during single-leg hop compared to nondancers with CAI. Thirdly, dancers with CAI showed a lower positive rate during the anterior drawer test compared to non-dancers with CAI (p=.019). Conclusion: Dancers with CAI demonstrated better ankle function and reduced mechanical instability compared to non-dancers with CAI. Therefore, to elucidate the underlying mechanisms of lateral ankle sprain and CAI development exacerbation in dancers, additional factors that can affect ankle sprain, such as visual dependence during postural control and evaluation in dance movements, should be explored.

Osborne-Cotterill lesion is an osteochondral fracture located in the posterolateral margin of the humeral capitellum, which may be associated with a defect of the radial head after an elbow dislocation. This lesion causes instability by affecting the lateral ulnar collateral ligament over its capitellar insertion, which is associated with a residual capsular laxity, thereby leading to poor coverage of the radial head, and hence resulting in frequent dislocations. We present a 54-year-old patient, a physician who underwent trauma of the left elbow after falling from a bike and suffered a posterior dislocation fracture of the elbow. The patient subsequently presented episodes of instability, and additional work-up studies diagnosed the occurrence of Osborne-Cotterill lesion. An open reduction and internal fixation of the bony lesion was performed, with reinsertion of the lateral ligamentous complex. Three months after surgery, the patient was asymptomatic, having a flexion of 130° and extension of 0°, and resumed his daily activities without any limitation. Currently, the patient remains asymptomatic 2 years after the procedure. Elbow instability includes a large spectrum of pathological conditions that affect the biomechanics of the joint. The Osborne-Cotterill lesion is one among these conditions. It is a pathology that is often forgotten and easily overlooked. Undoubtedly, this lesion requires surgical intervention.
