Background: The morphology and morphometry of the scapula and its glenoid fossa and acromion process play a significant role in the mechanics of shoulder joint. A variable morphology is found in glenoid fossa that has clinical implications. Aims and Objectives: The aim of the study was to evaluate the morphology and morphometry of dry scapula with emphasis on glenoid fossa and acromion process. Materials and Methods: A cross-sectional study was conducted at the department of anatomy, for a period of 6 months from January 2021 to June 2021. A total of 100 unpaired dry scapula were included in the study. The morphology and dimensions were measured. The dimensions were summarized as mean and standard deviation. Statistical analysis was done Chi-square test and student’s t-test based on the variable types. Results: Out of 100 scapulae studied, 48 were right sided and 52 were left sided. The mean of maximum length of the right scapula was 149.58±10.33 mm and the left side was 148.63±10.33 mm. Among the glenoid cavities, 54 were inverted comma shaped, 30 were pear shaped, and 16 were oval shaped. In one right-sided scapula Bony Spur Extends from Base of coracoid process to supra Scapular Notch. Conclusion: Size and shape of the glenoid cavity are directly related to the dislocation of shoulder joint and may affect the results of total shoulder arthroplasty and rotator cuff surgeries. The present study analyzed the morphological types and diameters of the glenoid cavity in adult scapulae to improve the efficacy and minimize the failure rates in shoulder arthroplasty particularly those involving the glenoid component of the shoulder joint.

Introduction:  The shoulder joint is the most important joint in the body and limitation of this joint movements affects the quality of life. Severe shoulder injury and glenohumeral arthritis causes shoulder dysfunction with devasting results, and to restore normal functions orthopaedic surgeon can perform total shoulder arthroplasty, or reverse shoulder prosthesis, or hemiarthroplasty.Lateral angle of the scapula becomes truncated and broadened and bears the glenoid cavity which articulates with the humerus in the shoulder joint. Shoulder joint is formed when the glenoid cavity is connected with the head of the humerus. This study was carried out to study the morphology and morphometry of the glenoid cavity as dimensions of the glenoid cavity are important in designing and fitting of glenoid components for total shoulder arthroplasty. Material and Methods: A total of 100 unpaired dry scapula were isolated from the department of Anatomy. Two groups were made according to the side of the scapula and were equally divided into 50 right and 50 left scapula each. Bones were segregated and inspected individually.To classifying shape of the glenoid fossa, presence or absence of a glenoid notch was used and were classified into 3 types, pear shaped or inverted comma shape in presence of a glenoid notch & oval in absence of notch. The pear shaped shows indistinct glenoid notch and the inverted comma shaped shows a distinct notch. Results: On the basis of presence or absence of the glenoid notch. 56%, 28% & 16% glenoid cavities of right side were pear shaped, inverted comma shaped and oval shaped respectively. On the left side 60%, 30% & 10%were pear shaped, inverted comma shaped and oval shaped respectively. In total 58% glenoid cavities were pear shaped, 29% were inverted comma shaped and 13% were oval shaped.Average length and breadth of scapulae included in this study was 134.07±13.87 mm and 98.43 ±9.58 mm respectively.Mean glenoid cavity index of right side was 48.12 to 86.87 %, while in left side it was 44.21 – 84.78%. Conclusion: The most common glenoid cavity was pear shaped followed by inverted comma shaped and the oval glenoid cavity. Mean glenoid cavity index of right side was 48.12 to 86.87 %, while in left side it was 44.21 – 84.78%.

Shoulder Arthroplasties

Abstract Currently, an increasing number of patients benefit from shoulder prosthesis implantation. Radiologists are therefore more often confronted with imaging examinations involving shoulder arthroplasty, whether during a dedicated examination or incidentally. Standard radiography is the first-line imaging modality in the follow-up of these implants, before the possible use of cross-sectional imaging modalities (computed tomography and magnetic resonance imaging), ultrasound, or nuclear medicine examinations. Shoulder arthroplasties are divided into three categories: reverse shoulder arthroplasty, total shoulder arthroplasty, and partial shoulder joint replacement (including humeral hemiarthroplasty and humeral head resurfacing arthroplasty). Each of these prostheses can present complications, either shared by all types of arthroplasty or specific to each. Infection, periprosthetic fractures, humeral component loosening, heterotopic ossification, implant failure, and nerve injury can affect all types of prostheses. Instability, scapular notching, and acromial fractures can be identified after reverse shoulder arthroplasty implantation. Glenoid component loosening and rotator cuff tear are specific complications of total shoulder arthroplasty. Progressive wear of the native glenoid is the only specific complication observed in partial shoulder joint replacement. Knowledge of different types of shoulder prostheses and their complications’ radiological signs is crucial for the radiologist to initiate prompt and adequate management.

Anatomic total shoulder arthroplasty (TSR) has been shown to generate good to excellent results for patients with osteoarthritis and a functioning rotator cuff. Many studies have reported that the glenoid component loosening and failure remain the most common long-term complication of total shoulder arthroplasty. The approach to glenoid component is critical because a surgeon should consider patient-specific anatomy, preserving bone stock and joint line restoration, for a good and durable shoulder function. Over the years, different glenoid design and materials have been tried in various configurations. These include cemented polyethylene, uncemented metal-backed and hybrid implants. Although advances in biomechanics, design and tribology have improved our understanding of the glenoid, the journey of the glenoid component in anatomic total shoulder arthroplasty has not yet reached its final destination. This article attempts to describe the evolution of the glenoid component in anatomic TSR and current practice.
