목적: 주관절은 인체에서 가장 안정적인 관절 중 하나지만, 견관절 다음으로 탈구와 골절이 흔히 발생한다. 이러한 손상은 발생 당시 기전과 환자의 나이 그리고 충격에 따라 다양하게 나타나는데 적절한 치료에도 불구하고 여러 가지 합병증들이 발생 가능하다. 이에 저자들은 외상후 합병증을 고찰하고자 한다. 대상 및 방법: 저자들은 일반적인 주관절 탈구의 합병증인 관절 운동제한, 불안정성, 그리고 관절 주위 이소성 골형성의 원인과 치료 등에 대해 기술하였다. 결과 및 결론: 주관절 주위 골절 이후 발생 가능한 합병증 중 부정유합, 불유합, 외상성 관절염 등에 대한 그 기전과 치료에 대해 기술하고자 한다.

이 종설은 주관절에서의 초음파 검사 방법을 서술하였으며 주관절의 구조물들은 표층에 위치하기 때문에 초음파 사용이 용이하고 동적인 검사와 건 측과의 비교를 쉽게 할 수 있다는 장점으로 인하여 환자의 병변에 대한 많은 정보를 제공해 준다. 주관절에서 초음파 검사는 주관절 주변의 건, 근육, 인대 와 점액낭의 비정상적 형태뿐만 아니라 미세 골절(occult fracture), 주관(cubital tunnel) 내의 척골 신경의 압박 유무도 평가할 수 있다. 향후 주관절의 연부조직 이상을 진단하는 수단으로서의 초음파의 가치는 점점 증가할 것이다.

Objective: Chronic lateral epicondylitis is a condition which becomes sore and tender on the lateral side of the elbow joint damaged from overuse and repetitive use of the extensor muscles of the forearm. The purpose of this study was to investigate the effects of flexion degrees in the elbow joint on extensor carpi radialis longus and brevis and biceps brachii muscles in individuals with healthy young adults. The main purpose of this study was to suggest the feasibility of optimal elbow angle during therapeutic eccentric exercise with resistance for strengthening of wrist extensors. Design: Cross-sectional study. Methods: Thirty health young adults (male 15, female 15) participated in this study. This study measured muscle activation in four different conditions of elbow flexion, $0^{\circ}$, $30^{\circ}$, $60^{\circ}$, and $90^{\circ}$ during eccentric exercise with weight loading in wrist extensors, extensor carpi radialis longus and brevis and biceps brachii muscles using surface electromyography. Results: The muscle activation of extensor carpi radialis showed a negative relationship with the degrees of elbow joint flexion. With increasing elbow flexion angles, the ECRL muscle activation amount was significantly lower (p<0.05). In contrast, the muscle activation of the ECRB muscle activation amount was significanlty higher (p<0.05). Conclusions: This study suggests that the eccentric exercise of wrist extension with selected activation of wrist extensor muscles according to elbow flexion positions, and suggests that the extensor carpi radialis longus and brevis will need to be strengthened for preventing and treating chronic lateral epicondylitis regardless of degrees of elbow joint flexion.

목적: 주관절의 생역학은 주관절 손상의 병인을 이해하고 임상적 치료의 과학적 기초를 제공하는 의학이다. 저자는 생역학적인 관점에서 주관절 손상의 진단과 치료의 개념을 요약하였다. 대상 및 방법: 주관절 역학은 크게 운동학, 동역학 그리고 이를 바탕으로 한 안정성의 분야로 나누어 설명할 수 있다. 이는 주관절을 구성하는 수동적 또는 능동적 구조물로 유지된다. 수동적 구조물은 골성 구조와 관절낭 및 측부인대들이 있으며 능동적 구조물은 주관절을 둘러싼 근육들이 해당된다. 이 구조물들이 유기적으로 작용하여 주관절의 안정성, 힘의 전달 그리고 운동을 유지한다. 결과 및 결론: 주관절의 생역학은 주관절 손상에 대한 수술적 치료에 대한 정보를 제공하며 새로운 주관절 인공대치물에 대한 개선 및 발전을 가져다 주며, 또한 주관절의 기초 연구에 기여 할 수 있는 학문이다.

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.

Purpose: The purpose of this study was to analyze the clinical results after Steindler flexoplasty. Materials and Methods: We analyzed 6 cases who had nearly normal finger and wrist joint flexion function, but could not flex elbow joint actively because of upper arm type brachial plexus injury. We performed operation during the period from February 1997 to July 2003. There were 5 males and 1 female with mean age of 28 years (range: $19{\sim}51$ years) when Steindler flexoplasty was done. The average follow-up period was 3 years 11 months (range: 12 months${\sim}$7 years 4 months). We assessed active range of motion of elbow joint, muscle power and elbow function by Mayer & Green grade scale at last follow-up. We assessed how much they were favorable for Steindler flexoplasty and had improvement of upper extremity function and correction of deformity. Results: Postoperative, flexion range of elbow joint improved to average $111.7^{\circ}$ (range: $90{\sim}130^{\circ}$). $25.8^{\circ}$ (range: $15{\sim}45^{\circ}$) in flexion contracture and $16.6^{\circ}$ (range: $10{\sim}35^{\circ}$) in pronation contracture were remained. Range of motion of elbow joint improved to average $85.3^{\circ}$ (range: $45{\sim}105^{\circ}$). Flexion power of elbow joint improved to Grade 5 in all cases. Postoperatively on Mayer & Green grade scale, there were excellent in 3 cases(50%), good in 2 cases(33.3%), fair in 1 case(16.7%). On patient's own assessment of functional improvement, there were excellent in 4 cases(66.6%), good in 1 case(16.7%) and fair in 1 case(l6.7%). Conclusion: Steindler flexoplasty can reserve good clinical results with being improved to active flexion of elbow joint in cases who have functional hand and wrist, but paralysis upper arm muscle in brachial plexus injury.

The human arm is modeled by three rigid bodies(the upper arm, the forearm and the hand)with seven degree of freedom(three in the shoulder, two in the elbow and two in the wrist). The objective of this work is to present a method to determine the three-dimensional kinematics of the human elbow joint using a magnetic tracking device. Euler angle were used to determine the elbow flexion-extension, and the pronation-supination. The elbow motion for the various driving conditions is measured through the driving test using a simulator. Discomfort levels of elbow joint motions were obtained as discomfort functions, which were based on subjects' perceived discomfort level estimated by magnitude estimation. The results showed that the discomfort posture of elbow joint motions occurred in the driving motion.

Background: Our aim is to determine the interobserver reliability for surgeons to detect Hill-Sachs lesions on magnetic resonance imaging (MRI), the certainty of judgement, and the effects of surgeon characteristics on agreement. Methods: Twenty-nine patients with Hill-Sachs lesions or other lesions with a similar appearance on MRIs were presented to 20 surgeons without any patient characteristics. The surgeons answered questions on the presence of Hill-Sachs lesions and the certainty of diagnosis. Interobserver agreement was assessed using the Fleiss' kappa (κ) and percentage of agreement. Agreement between surgeons was compared using a technique similar to the pairwise t-test for means, based on large-sample linear approximation of Fleiss' kappa, with Bonferroni correction. Results: The agreement between surgeons in detecting Hill-Sachs lesions on MRI was fair (69% agreement; κ, 0.304; p<0.001). In 84% of the cases, surgeons were certain or highly certain about the presence of a Hill-Sachs lesion. Conclusions: Although surgeons reported high levels of certainty for their ability to detect Hill-Sachs lesions, there was only a fair amount of agreement between surgeons in detecting Hill-Sachs lesions on MRI. This indicates that clear criteria for defining Hill-Sachs lesions are lacking, which hampers accurate diagnosis and can compromise treatment.
