  • Coracoid Graft Union: a Quantitative Assessment by Computed Tomography in Primary and Revision Latarjet Procedure

Small,MDb,*, Laurence D. Higgins, MD, MBAc aDepartment of Radiology, NYU Langone Medical Center, New York, NY, USA bDepartment of Radiology, Brigham and Women’s Hospital, Boston, MA, USA cBoston Shoulder Institute, Boston, MA, USA Background: The goal of the Latarjet procedure is restoration of shoulder stability enabled by accurate graft positioning and union. This study aimed to establish a reproducible method of quantitatively assess- ing coracoid graft osseous union percentage (OUP) using computed tomography (CT) scans and to determine the effect of other factors on the OUP. Materials and methods: Postoperative CT scans of 41 consecutive patients treated with the open Latarjet procedure (37% primary, 63% revision) for anterior glenohumeral instability were analyzed for the OUP, position of the graft, and screw type and angle. Two musculoskeletal radiologists independently exam- ined the images 2 times, and intraobserver and interobserver reliability was calculated using intraclass correlation coefficient (ICC). Results: Mean OUP was 66% (range, 0%-94%) using quantitate methods, with good intraobserver re- liability (ICC = 0.795) and interobserver reliability (ICC = 0.797). Nonunion and significant graft resorption was found in 2 patients. No significant difference was found in the mean OUP in the primary (63%) vs. revision Latarjet procedure (67%). Grafts were flush in 39%, medial in 36%, and lateral in 8%. The medial and neutral graft position was associated with slightly higher OUP (72% and 69%) compared with lateral (65%).

Our research aim was to evaluate annual hospitalizations for shoulder dislocation in paediatric patients in Italy from 2001 to 2014, on the basis of the official data source as hospitalization reports. The second purpose was to investigate geographical diversification in hospitalization for shoulder dislocation in regions of Italy. The last aim was to make statistical predictions of the number of shoulder dislocation hospitalization volumes and rates in skeletally immature patients based on data from 2001 to 2014.

  • History of Surgical Intervention of Anterior Shoulder Instability
    J Shoulder Elbow Surg (2016) 25, e139–e150 www.elsevier.com/locate/ymse History of surgical intervention of anterior shoulder instability David M. Levy,MD*, Brian J. Cole, MD, MBA, Bernard R. Bach Jr, MD Department of Orthopaedic Surgery, Rush University Medical Center, Chicago, IL, USA Background: Anterior glenohumeral instability most commonly affects younger patients and has shown high recurrence rates with nonoperative management. The treatment of anterior glenohumeral instability has undergone significant evolution over the 20th and 21 centuries. Methods: This article presents a retrospective comprehensive review of the history of different operative techniques for shoulder stabilization. Results: Bankart first described an anatomic suture repair of the inferior glenohumeral ligament and anteroinferior labrum in 1923. Multiple surgeons have since described anatomic and nonanatomic repairs, and many of the early principles of shoulder stabilization have remained even as the techniques have changed. Some methods, such as the Magnusson-Stack procedure, Putti-Platt procedure, arthroscopic stapling, and transosseous suture fixation, have been almost completely abandoned. Other strategies, such as the Bankart repair, capsular shift, and remplissage, have persisted for decades and have been adapted for arthroscopic use. Discussion: The future of anterior shoulder stabilization will continue to evolve with even newer prac- tices, such as the arthroscopic Latarjet transfer. Further research and clinical experience will dictate which future innovations are ultimately embraced. Level of evidence: Review Article © 2016 Journal of Shoulder and Elbow Surgery Board of Trustees. Keywords: Anterior glenohumeral instability; dislocation; subluxation; shoulder stabilization; arthroscopic; Bankart Because of its relative lack of bony limitations and ex- Hovelius et al60 in a prospective study of 229 primary dis- tensive range of motion, the shoulder is the most commonly locations treated nonoperatively.

  • Open Latarjet Anterior Shoulder Stabilization
    UW HEALTH SPORTS REHABILITATION Rehabilitation Guidelines for Open Latarjet Anterior Shoulder Stabilization The anatomic configuration of the shoulder joint (glenohumeral joint) is often compared to a golf ball on a tee. This analogy is used because the articular surface of the round humeral head (upper most part of the arm) is approximately four times greater than that of the relatively flat shoulder blade face (glenoid fossa). The stability and movement of the shoulder is controlled by Figure 1 L to R: Lateral view of glenoid post laterjay with humerous removed.
