Description

상완관절 보조장치{Apparatus for assisting shoulder joint}Apparatus for assisting shoulder joint}

본 발명은 상완관절 보조장치에 관한 것으로, 더욱 상세하게는, 상완 관절(Shoulder joint)의 상완골 두(Head of humerus)와 관절와(Glenoid cavity)에 설치되어 상완 관절을 보조하는 장치에 관한 것이다.The present invention relates to a humeral joint assist device, and more specifically, to a device installed on the head of humerus and glenoid cavity of the shoulder joint to assist the humeral joint.

도 1 및 도 2를 참조하면, 회전근 개(Rotator cuff muscles)는, 상완 관절(Shoulder joint)을 안정시키기 위한 근육을 의미한다. 이러한 회전근 개는, 견갑하근(Subscapularis), 극상근(Supraspinatus), 극하근(Infraspinatus) 및 소원근(Teres minor)의 4가지 근육으로 이루어진다. 여기서, 견갑하근, 극상근, 극하근 및 소원근은, 기시부(Root)는 각각 다르지만, 대결절(Greater tubercle)에 부착하기 전 상완골 두(Head of humerus) 주위를 둘러싸며 하나의 건으로 합쳐져 부착된다는 특징이 있다.Referring to Figures 1 and 2, rotator cuff muscles refer to muscles for stabilizing the shoulder joint. This rotator cuff is made up of four muscles: Subscapularis, Supraspinatus, Infraspinatus, and Teres minor. Here, the subscapularis, supraspinatus, infraspinatus, and teres minor muscles each have different roots, but they surround the head of the humerus before attaching to the greater tubercle, and are combined into a single tendon before attaching to the greater tubercle. There is.

이러한 회전근 개의 구조는, 상완 관절에 대하여 짝힘(Force couple)을 가하여, 상완 관절의 안정성에 기여한다. 즉, 상완 관절을 정면에서 보았을 때에는 삼각근(Deltoid muscle)과 극상근이, 상완관절을 하부에서 보았을 때에는 견갑하근과 극하근 및 소원근이 짝힘을 형성한다.This structure of the rotator cuff applies a force couple to the humeral joint, contributing to the stability of the humeral joint. In other words, when the humeral joint is viewed from the front, the deltoid muscle and supraspinatus form a pair, and when the humeral joint is viewed from below, the subscapularis, infraspinatus, and teres minor form a paired force.

최근 생역학적 연구에서는, 회전근 개의 상완 관절 안정성 역할 중, 상완골 두 감압(Head of humerus depressor) 역할보다, 상완골 두와 관절와 사이의 요부 압박(Concavity compression) 작용을 제공하여 전방거상과 회전 운동의 고정 지렛대 (Fixed fulcrum) 역할을 하는 것이 보다 더 중요하게 부각되고 있다. 그러나 광범위 회전근 개 파열로 회전근 개의 상완 관절 안정성에 기여하는 역할이 소실된 경우, 짝힘이 소실되게 된다. 그리고 이 경우, 상완 관절의 회전 중심축(Center of rotation)이 안정성을 잃고 상방으로 이동하게 되어, 팔을 들어 올리지 못하는 가성마비 등의 소견이 나타나게 되고, 상완 관절은 그 기능적 역할을 제대로 할 수 없게 된다.Recent biomechanical studies have shown that among the humeral joint stability roles of the rotator cuff, rather than serving as a head of humerus depressor, it provides concavity compression between the humeral head and the glenoid, providing a fixed lever for anterior elevation and rotation movements. (Fixed fulcrum) role is becoming more important. However, if the rotator cuff's role in contributing to humeral joint stability is lost due to an extensive rotator cuff tear, the paired force is lost. In this case, the center of rotation of the humeral joint loses stability and moves upward, resulting in findings such as pseudoparesis, which prevents the arm from being raised, and the humeral joint cannot properly perform its functional role. do.

이렇듯, 상완 관절 안정화 역할이 소실된 회전근 개의 광범위 파열 환자, 특히 팔을 능동적으로 들어 올리는 것이 불가능한 가성마비 환자에 대한 치료로 역행성 상완관절 보조장치 치환술, 상부 관절낭 재건술 등 여러 방법이 시도되고 있다. 그러나 이는 비해부학적 재건 방법이기 때문에 이와 관련된 여러 문제점들이 지적되고 있는 실정이다. 결국 이러한 환자들에서 가장 좋은 이론적 치료 방법은 회전근 개의 가장 중요한 역할 중 하나인 상완골 두의 회전 중심축을 유지시켜 줄 수 있는 장치를 개발하는 것이다.As such, various methods, such as retrograde humeral joint replacement and upper joint capsule reconstruction, are being attempted as treatment for patients with extensive rotator cuff rupture who have lost their role in stabilizing the humeral joint, especially for patients with pseudoparesis who are unable to actively lift the arm. However, because this is a non-anatomical reconstruction method, several problems related to it have been pointed out. Ultimately, the best theoretical treatment method for these patients is to develop a device that can maintain the central axis of rotation of the humeral head, which is one of the most important roles of the rotator cuff.
