3-D CT is the Most Reliable Imaging Modality When Quantifying Glenoid Bone Loss

Julie Y. Bishop MD, Grant L. Jones MD, Michael A. Rerko MD, Chris Donaldson MD

Posttraumatic anterior shoulder instability is associated with anterior glenoid bone loss, contributing to recurrence. Accurate preoperative quantification of bone loss is paramount to avoid failure of a soft tissue stabilization procedure as bone reconstruction is recommended for glenoid defects greater than 20% to 27%.

Immediate Postoperative Radiographs After Shoulder Arthroplasty Are Often Poor Quality and Do Not Alter Care

Surena Namdari MD, MSc, Jason E. Hsu MD, Matthew Barron BS, G. Russell Huffman MD, MPH, David Glaser MD

It is technically difficult to obtain high-quality, postoperative shoulder radiographs immediately after surgery. Further, poor-quality radiographs may be unlikely to change clinical practice or improve patient outcomes. We therefore questioned the value of routine postoperative radiographs after shoulder arthroplasty.

Does Humeral Lengthening With a Monolateral Frame Improve Function?

Abhijit Y. Pawar MD, Thomas H. McCoy MD, Austin T. Fragomen MD, S. Robert Rozbruch MD

Humeral lengthening by distraction osteogenesis historically has relied on bulky circular external fixators. Advances in fixator technology have allowed for the use of monolateral frames. However, it is unclear whether and to what degree function is improved after humeral lengthening.

Motion and Pain Relief Remain 23 Years After Manipulation Under Anesthesia for Frozen Shoulder

Heidi Vastamäki MD, Martti Vastamäki MD, PhD

Manipulation under anesthesia (MUA) as treatment for idiopathic frozen shoulder increases motion, provides pain relief, and restores function, but it is unclear whether the improvements persist long term.

To What Degree do Shoulder Outcome Instruments Reflect Patients’ Psychologic Distress?

Young Hak Roh MD, Jung Ho Noh MD, Joo Han Oh MD, Goo Hyun Baek MD, Hyun Sik Gong MD

Psychologic distress contributes to symptom severity in patients with several musculoskeletal disorders. While numerous shoulder outcome instruments are used it is unclear whether and to what degree psychologic distress contributes to the scores.

Rotator Cuff Integrity Correlates With Clinical and Functional Results at a Minimum 16 Years After Open Repair

Martti Vastamäki MD, PhD, Martina Lohman MD, PhD, Niclas Borgmästars MD

Recurrent or persistent defects in the rotator cuff after its repair are common. Short- and medium-term surveys have revealed, after open repair, patients with an intact rotator cuff have increased function and ROM. However, no long-term studies have verified cuff integrity on MR arthrography or correlated it with clinical and functional outcomes.

Surgeon Volume is Associated With Cost and Variation in Surgical Treatment of Proximal Humeral Fractures

Nitin B. Jain MD, MSPH, Ifedayo Kuye BS, Laurence D. Higgins MD, Jon J. P. Warner MD

The issue of rising costs will likely dominate the healthcare debate in the forthcoming years.

Does Open Repair of Anterosuperior Rotator Cuff Tear Prevent Muscular Atrophy and Fatty Infiltration?

Marion Schino MD, Bernard Augereau MD, Christophe Nich MD, PhD

Repair of cuff tears involving rotator interval reportedly improves function. However, it is unclear whether successful repair prevents shoulder degenerative changes.

Does Augmentation with a Reinforced Fascia Patch Improve Rotator Cuff Repair Outcomes?

Andrew R. Baker MS, Jesse A. McCarron MD, Carmela D. Tan MD, Joseph P. Iannotti MD PhD, Kathleen A. Derwin PhD

Scaffold devices are used to augment rotator cuff repairs in humans. While the strength of a novel poly-L-lactic acid-reinforced (human) fascia patch has been documented, it is unclear whether such patches will enhance the strength or likelihood of healing of rotator cuff repairs.

Neer Modification of Open Bankart Procedure: What are the Rates of Recurrent Instability, Functional Outcome, and Arthritis?

Pascal Boileau MD, E. Fourati MD, Ryan Bicknell MD, MSc

Neer modified the Bankart procedure by combining a superoinferior capsular shift with the labral reattachment. The theoretical advantages of the modification were that such a procedure would restore the patient’s anatomy and also treat the repeated capsular stretching encountered in anteroinferior instability without limiting external rotation and, thereby reducing the risk of arthritis.
