Reverse Total Shoulder Arthroplasty Improves Function in Cuff Tear Arthropathy

Betsy M. Nolan MD, Elizabeth Ankerson BS, J. Michael Wiater MD

Early failure due to glenoid loosening with anatomic total shoulder arthroplasty in patients with severe rotator cuff deficiency led to the development of the reverse ball-and-socket shoulder prosthesis. The literature reports improved short-term pain and function scores following modern reverse total shoulder arthroplasty (RTSA) in patients with cuff tear arthropathy (CTA).

Outcomes of Nonoperatively Treated Displaced Scapular Body Fractures

Apostolos Dimitroulias MD, Kenneth G. Molinero DO, Daniel E. Krenk DO, Matthew T. Muffly MS, Daniel T. Altman MD, Gregory T. Altman MD

Displaced scapular body fractures most commonly are treated conservatively. However there is conflicting evidence in the literature regarding the outcomes owing to retrospective design of studies, different classification systems, and diverse outcome tools.

Greater Strength Increase with Cyst Decompression and SLAP Repair than SLAP Repair Alone

Gita Pillai MD, Jason R. Baynes MD, James Gladstone MD, Evan L. Flatow MD

Treatment of symptomatic spinoglenoid cysts has been controversial with options ranging from observation, to open excision, to arthroscopic decompression with or without labral repair. It has recently been suggested that isolated repair of SLAP lesions without cyst decompression can restore function in patients with spinoglenoid cysts and SLAP lesions.

Can Reverse Shoulder Arthroplasty be Used with Few Complications in Rheumatoid Arthritis?

Anders Ekelund MD, PhD, Ragnhild Nyberg PT

Many patients with rheumatoid arthritis develop superior migration of the humeral head because of massive cuff tears, causing loss of active motion. Reverse shoulder arthroplasty could potentially restore biomechanical balance but a high incidence of glenoid failure has been reported. These studies do not, however, typically include many patients with rheumatoid arthritis (RA) and it is unclear whether the failure rates are similar.

The Anatomy of the Supraclavicular Nerve During Surgical Approach to the Clavicular Shaft

Tyler Nathe MD, Susan Tseng MD, Brad Yoo MD

Surgery for clavicular shaft fractures is becoming more common but incisional and chest wall numbness reportedly occurs in 10% to 29% of patients. This may be the result of iatrogenic injury to the supraclavicular nerve branches.

Erratum to: Shoulder Arthroplasties have Fewer Complications than Hip or Knee Arthroplasties in US Veterans

Does a Positive Neer Impingement Sign Reflect Rotator Cuff Contact with the Acromion?

Xiaofeng Jia MD, PhD, Jong Hun Ji MD, Vinodhkumar Pannirselvam MD, Steve A. Petersen MD, Edward G. McFarland MD

One possible cause of shoulder pain is rotator cuff contact with the superior glenoid (cuff-glenoid contact) with the arm in flexion, as occurs during a Neer impingement sign. It has been assumed that the pain with a Neer impingement sign on physical examination of the shoulder was secondary to the rotator cuff making contact with the anterior and lateral acromion.

Total Shoulder Arthroplasty in Older Patients: Increased Perioperative Morbidity?

Eric T. Ricchetti MD, Joseph A. Abboud MD, Andrew F. Kuntz MD, Matthew L. Ramsey MD, David L. Glaser MD, Gerald R. Williams MD

More elderly patients are becoming candidates for total shoulder arthroplasty with an increase in frequency of the procedure paralleling the rise in other total joint arthroplasties. Controversy still exists, however, regarding the perioperative morbidity of total joint arthroplasty in elderly patients, particularly those 80 years of age and older.

Does the Upward Migration Index Predict Function and Quality of Life in Arthroscopic Rotator Cuff Repair?

Peter C. Lapner MD, FRCSC, Yingua Su BSc (H), David Simon MD, Salah El-Fatori MD, Emilio Lopez-Vidriero MD, PhD

Although upward humeral head migration is a well-recognized phenomenon in patients with tears of the cuff, it is unclear whether it relates to patient function after cuff repair. The upward migration index (UMI) assesses proximal migration of the humeral head while controlling for patients’ bony morphologic features.

Bioabsorbable Tricalcium Phosphate Bone Cement Strengthens Fixation of Suture Anchors

Rayshad Oshtory MD MBA, Derek P. Lindsey MS, Nicholas J. Giori MD, PhD, Faisal M. Mirza MD, FRCSC

Failure of suture anchor fixation in rotator cuff repair can occur at different interfaces. Prior studies show fixation at the bone-anchor interface can be augmented using polymethylmethacrylate (PMMA) cement, and screw fixation into bone can be strengthened using bioabsorbable tricalcium phosphate cement.
