A Bibliometric Analysis: 200 Most Cited Papers in the Field of Shoulder Surgery

Abstract

This study aims to review anatomical restoration of glenoid version and humeral head centring in anatomic total shoulder replacements (ATS) in B2 glenoids using CT scans.Background: Uncorrected retroversion in B2 glenoid causes eccentric loading and failure of the glenoid component in TSA. It also leads to humeral head decentring with posterior rim loading, early glenoid wear and component loosening.Methods: This is a retrospective review of TSA for glenohumeral osteoarthritis with B2 glenoid morphology. All polyethylene posterior wedge augmented glenoid component (Tornier Aequalis Perform Plus, TN, USA) was used. Patients underwent pre and post operative CT scans. Glenoid version was calculated using neoglenoid line and medial scapula border as reference point. This was done at mid-glenoid height on axial CT-scan with best-fit ellipse method. Pre and Post-operative humeral head centering was calculated using offset of centre of humeral head with plane of scapula on axial CT-Scan. During surgery, eccentric reamer with depth stop on paleoglenoid was used to ream neoglenoid to accept posterior wedge augment.Results: Ten patients with 11 TSA were recruited between June 2017 and July 2018. Mean age was 59 (45-80) years with 5 females and 5 males (one patient had bilateral arthroplasty). Average follow-up interval between CT scan and surgery was 11 months. Mean preoperative retroversion was 16(13-23) degrees. This was corrected to a mean of 0 degrees retroversion postoperatively, ranging from 8 degrees of anteversion to 3 degrees of retroversion. All patients achieved retroversion less than 5 degrees. Hence, 63% had good radiological correction (0-5 degrees retroversion). Mean pre-operative humeral head scapula offset was 9.7mm (13.7-2.9mm). Humeral head was well centred post-operatively with mean humeral scapula alignment offset of 2.1(0.8e4.5) mm posteriorly. All the cases had well-centered humeral head postoperatively with offset less than 5 mm.Conclusions: Total shoulder replacement in B2 glenoid is technically demanding. Our radiological results show favourable outcome in terms of correction of glenoid retroversion and eliminating posterior instability using wedge glenoid component.

The 100 most impactful articles on the rotator cuff: an altmetric analysis of online media

“…European authors are widely regarded to be at the forefront of shoulder research, with several of the major developments in the field of shoulder surgery occurring in France (e.g. Goutallier classification, Grammont prosthesis, Latarjet procedure) [18]. Therefore, it is not surprising that much of the online attention surrounding rotator cuff research is derived from European articles.…”
