Surgical Technique Arthroscopic Posterior Glenoidplasty for Posterosuperior Glenoid Impingement in Throwing Athletes

Christophe Lévigne MD, Jérome Garret MD, Sophie Grosclaude MD, Florent Borel MD, Gilles Walch MD

Posterosuperior glenoid impingement (PSGI) is the repetitive impaction of the supraspinatus tendon insertion on the posterosuperior glenoid rim in abduction and external rotation. While we presume the pain is mainly caused by mechanical impingement, this explanation is controversial. If nonoperative treatment fails, arthroscopic débridement of tendinous and labral lesions has been proposed but reportedly does not allow a high rate of return to sports. In 1996, we proposed adding abrasion of the bony posterior rim, or glenoidplasty.

Subscapularis Release in Shoulder Replacement Determines Structural Muscular Changes

Lieven Franciscus Wilde MD, PhD, Tineke Coninck BSc, Francis Neve MD, Bart M. Berghs MD

Osteotomy of the lesser tuberosity in shoulder arthroplasty allows bony healing of the subscapularis tendon but does not prevent fatty degeneration in its muscle. Occurrence or increase in fatty degeneration may depend on the surgical technique.

Are Shoulders with A Reverse Shoulder Prosthesis Strong Enough? A Pilot Study

Tjarco D. W. Alta MD, H. E. J. Veeger PhD, Thomas W. J. Janssen PhD, W. Jaap Willems MD, PhD

It has been suggested that limited active ROM of reverse shoulder prostheses relates to lack of strength. However, the postoperative strength has not been quantified.

Passive Range of Motion Characteristics in the Overhead Baseball Pitcher and Their Implications for Rehabilitation

Kevin E. Wilk PT, DPT, Leonard C. Macrina MSPT, SCS, CSCS, Christopher Arrigo MS, PT

Repetitive overhead throwing motion causes motion adaptations at the glenohumeral joint that cause injury, decrease performance, and affect throwing mechanics. It is essential to define the typical range of motion (ROM) exhibited at the glenohumeral joint in the overhead thrower.

Arthroscopically Determined Degree of Injury After Shoulder Dislocation Relates to Recurrence Rate

Vicente Gutierrez MD, Juan Edo Monckeberg MD, PhD, Miguel Pinedo MD, Fernando Radice MD

The glenohumeral joint is the most mobile articulation in the body and the most commonly dislocated diarthrodial joint with peaks in the incidence of dislocation occurring during the second and sixth decades. Age at the time of the initial dislocation is inversely related to the recurrence rate. Traumatic anterior instability is often associated with intraarticular injuries. The frequency of injuries may increase with dislocation or subluxation episodes.

An Acute Throwing Episode Decreases Shoulder Internal Rotation

W. Ben Kibler MD, Aaron Sciascia MS, ATC, NASM-PES, Stephanie Moore MS, ATC

Glenohumeral internal rotation (GIR) and total arc of motion (TAM) decrease, whereas external rotation (GER) may increase in throwing. Although decreased GIR has been documented after throwing, its time course for recovery and the effect of pitching role have not.

Reliability of Scapular Classification in Examination of Professional Baseball Players

Todd S. Ellenbecker DPT, MS, SCS, OCS, CSCS, W. Ben Kibler MD, David S. Bailie MD, Roger Caplinger ATC, George J. Davies DPT, SCS, ATC, CSCS, Bryan L. Riemann PhD, ATC

Clinically evaluating the scapulothoracic joint is challenging. To identify scapular dyskinesis, clinicians typically observe scapular motion and congruence during self-directed upper extremity movements. However, it is unclear whether this method is reliable.

Surgical Treatment of Neer Group VI Proximal Humeral Fractures: Retrospective Comparison of PHILOS® and Hemiarthroplasty

Christian Spross MD, Andreas Platz MD, Matthias Erschbamer MD, PhD, Thomas Lattmann MD, Michael Dietrich MD

Neer Group VI proximal humeral fractures often are related to persistent disability despite surgical treatment. We retrospectively compared the outcome after open reduction and internal fixation with the PHILOSplate or primary hemiarthroplasty in patients with Neer Group VI fractures focusing on complications, shoulder function, health-related quality of life (SF-36), and potential risk factors for complications.

Intraarticular Abnormalities in Overhead Athletes Are Variable

Ashvin K. Dewan MD, Juan Garzon-Muvdi MD, Steve A. Petersen MD, Xiaofeng Jia MD, PhD, Edward G. McFarland MD

The cause of shoulder pain and dysfunction in the overhead athlete can be variable. Several studies illustrate the wide variety of lesions seen at the time of arthroscopy in overhead athletes who require surgery but it is unclear whether these differ by sport.

The Natural History of Idiopathic Frozen Shoulder: A 2- to 27-year Followup Study

Heidi Vastamäki MD, Jyrki Kettunen PT, PhD, Martti Vastamäki MD, PhD

The natural history of spontaneous idiopathic frozen shoulder is controversial. Many studies claim that complete resolution is not inevitable. Based on the 40-year clinical experience of the senior author, we believed most patients with idiopathic frozen shoulder might have a higher rate of resolution than earlier thought.
