BACKGROUND AND PURPOSE Despite good clinical results with the reverse total shoulder arthroplasty, inferior scapular notching remains a concern. We evaluated 6 different solutions to overcome the problem of scapular notching. METHODS An average and a "worst case scenario" shape in A-P view in a 2-D computer model of a scapula was created, using data from 200 "normal" scapulae, so that the pos...

[Purpose] This study was performed to evaluate the clinical effect of the dual-wall pushup plus exercise in patients with scapular dyskinesis with a winged or tipped scapula. [Subject] A 32-year-old man with scapular dyskinesis participated in this study. [Methods] The subject performed the dual-wall pushup plus for 2 months, 4 days a week, for an average of 2 hours each day. The scapular dyski...

The purpose of this study was to determine the intrarater and interrater reliability of a clinical evaluation system for scapular dysfunction. No commonly accepted terminology presently exists for describing the abnormal dynamic scapular movement patterns that are commonly associated with shoulder injury. A method of observation was devised for clinical evaluation of scapular dysfunction. Blind...

conclusions the dominant side scapula of asymptomatic racquet players showed increased external rotation and elevation as compared to the non-dominant side. also, reduced shoulder internal rotation, extension and adduction and gain in shoulder external rotation was observed on the dominant side of racquet players when compared to the control group. materials and methods 46 asymptomatic professi...

Primary scapular winging typically results from palsies of the serratus anterior, trapezius, and rhomboid muscles, which are caused by injury to the long thoracic nerve, spinal accessory nerve, and dorsal scapular nerve, respectively. The Eden-Lange procedure has become the surgical treatment of choice for scapular winging from trapezius palsy because other surgical procedures have high failure...

Abstract Introduction Scapular dyskinesis is a condition responsible for alteration of the normal position and kinematics of the scapula rather than a disease. It can thus be found in healthy individuals or be responsible for a syndrome characterised by several symptoms and objective findings, called SICK, which indicates the main features of the disease. Our purpose is to describe the anatomic...

The aim of this study was to establish the optimal methodology for skin-fixed measurement of the scapula during dynamic movement. This was achieved by comparing an optimally positioned Scapula Tracker device (ST) to a previously described palpation device, taken as the true measure of scapular kinematics. These measurements were compared across a range of calibration positions, including the us...

Introduction: Analgesia following shoulder surgery commonly uses interscalene nerve blockade. When contraindicated (i.e. respiratory compromise), suprascapular nerve blockade can provide a viable alternative. Although a number of techniques have been used, Barber in 2005 described a simple method using anatomical landmarks. While theoretically straightforward, substantive evidence supporting th...

BACKGROUND No clear trend has emerged from the literature regarding three-dimensional (3D) translations of the humerus relative to the scapula in shoulders with rotator cuff tears (RCTs). The purpose of this study was to evaluate the kinematics of RCT shoulders using 3D-to-two-dimensional (2D) model-to-image registration techniques. METHODS Dynamic glenohumeral kinematics during scapular plan...
