Biomechanics Analysis of Latissimus Dorsi Transfer in Reverse Shoulder Arthroplasty
Reverse total shoulder arthoplasty (RTSA) is commonly used in patients with cuff tear arthropathy (CTA) to relief pain and to restore active humeral elevation ROM [1]. The reverse prosthetic designs medialise the humeral centre of rotation increasing the Deltoid moment arm and its performance [2]. However, clinical studies have shown that patients with RTSA usually show poor humeral internal/ex...
متن کاملBiomechanics of the shoulder.
The shoulder is a complex of 5 joints and disturbances at any of these joints are likely to interfere with the smooth rhythm observed in movements of this complex. The overall ratio of scapulothoracic to glenohumeral movement of 1:2 is made possible by a clockwork mechanism that involves movements at these 2 articulations with axial rotation of the clavicle that connects the shoulder girdle to ...
متن کاملCurrent concepts of shoulder arthroplasty for radiologists: Part 2--Anatomic and reverse total shoulder replacement and nonprosthetic resurfacing.
OBJECTIVE The purpose of this article is to provide a review of the indications for shoulder arthroplasty, describe preoperative imaging assessment, present new and modified designs of shoulder arthroplasty, illustrate normal and abnormal postoperative imaging findings, and review key radiographic measurements. CONCLUSION Knowledge of the physiologic purpose, orthopedic trends, imaging findin...
متن کاملSpinal neoplastic instability: biomechanics and current management options.
BACKGROUND Often the spine is afflicted from primary or metastatic neoplastic disease, which can lead to instability. Instability can cause deformity, pain, and spinal cord compression and is an indication for surgery. Although overt instability is uniformly agreed upon, it is sometimes difficult for specialists to agree on subtle degrees of instability due to lack of objective criteria. METH...
متن کاملIndications for reverse shoulder replacement: a systematic review.
The outcome of an anatomical shoulder replacement depends on an intact rotator cuff. In 1981 Grammont designed a novel large-head reverse shoulder replacement for patients with cuff deficiency. Such has been the success of this replacement that it has led to a rapid expansion of the indications. We performed a systematic review of the literature to evaluate the functional outcome of each indica...
