Axillary View: Arthritic Glenohumeral Anatomy and Changes After Ream and Run

Frederick A. Matsen MD, Akash Gupta MD

The technique and results of shoulder arthroplasty are influenced by glenohumeral pathoanatomy. Although some authors advocate a routine preoperative CT scan to define this anatomy, ordering a CT scan substantially increases the cost and the radiation exposure for the patient.

Assessing Shoulder Motion in Children: Age Limitations to Mallet and ABC Loops

Michael L. Pearl MD, Fabian Bunt BS, Michaela Pearl BS, Nina Lightdale-Miric MD, Susan Rethlefsen PT, DPT, Jennifer Loiselle OTRL

Shoulder ROM and function of the shoulder are difficult to evaluate in young children. There has been no determination of the age at which children can comply with the current assessment tools in use, but doing so would be important, because it gives us more accurate insight into the development and assessment of shoulder functional ROM in young children.

Rotator Cuff Tear and Glenohumeral Instability

M. Mustafa Gomberawalla MD, Jon K. Sekiya MD

The rotator cuff plays a significant role in the static and dynamic stability of the glenohumeral joint. Rotator cuff tears may occur after shoulder dislocations, whether in younger athletes or older patients with age-related tendon degeneration. Untreated tears may cause persistent pain, dysfunction, instability, and degenerative changes. A thorough understanding of when to look for rotator cuff tears after shoulder dislocations and how best to manage them may decrease patients’ pain and improve function.

The Detrimental Effects of Systemic Ibuprofen Delivery on Tendon Healing Are Time-Dependent

Brianne K. Connizzo BS, Sarah M. Yannascoli MD, Jennica J. Tucker BS, Adam C. Caro DVM, Corinne N. Riggin BS, Robert L. Mauck PhD, Louis J. Soslowsky PhD, David R. Steinberg MD, Joseph Bernstein MD

Current clinical treatment after tendon repairs often includes prescribing NSAIDs to limit pain and inflammation. The negative influence of NSAIDs on bone repair is well documented, but their effects on tendon healing are less clear. While NSAIDs may be detrimental to early tendon healing, some evidence suggests that they may improve healing if administered later in the repair process.

A Patient-derived Constant-Murley Score is Comparable to a Clinician-derived Score

Ofer Levy MD, Omar Haddo BSc, Samir Massoud MCChB, Hannan Mullett MB, BCh, Ehud Atoun MD

Although there are many advantages to patient-based assessment for musculoskeletal conditions, one common problem is that many of these assessments are perceived to be subjective. To overcome this limitation for patient-based shoulder evaluation, we developed a modified Constant-Murley score that allows patients to complete subjective and objective sections of the score.

Advantages of Arthroscopic Transosseous Suture Repair of the Rotator Cuff without the Use of Anchors

Shigehito Kuroda MD, Noriyuki Ishige MD, Motohiko Mikasa MD

Although arthroscopic anchor suturing is commonly used for rotator cuff repair and achieves good results, certain shortcomings remain, including difficulty with reoperation in cases of retear, anchor dislodgement, knot impingement, and financial cost. In 2005, we developed an anchorless technique for arthroscopic transosseous suture rotator cuff repair.

Is Premorbid Glenoid Anatomy Altered in Patients with Glenohumeral Osteoarthritis?

Eric T. Ricchetti MD, Michael D. Hendel MD, PhD, David N. Collins MD, Joseph P. Iannotti MD, PhD

Restoration of native, premorbid glenoid anatomy may be a goal in component placement during total shoulder arthroplasty. However, if patients with unilateral glenohumeral osteoarthritis are predisposed to the development of arthritis owing to abnormal native glenoid anatomy, this recommendation may be inappropriate.

Weber Osteotomy for Large Hill-Sachs Defects: Clinical and CT Assessments

Alexandra L. Brooks-Hill BPHE, MD, DipSportMed, Bruce B. Forster MD, Case Wyngaarden BSc, MD, Robert Hawkins MD, William D. Regan MD

The Weber derotation osteotomy is an uncommon procedure that typically is reserved for patients with engaging Hill-Sachs defects who have had other surgical treatments for shoulder instability fail. It is unknown whether the desired humeral derotation actually is achieved with the Weber osteotomy.

Cerebral Desaturation During Shoulder Arthroscopy: A Prospective Observational Study

Dane Salazar MD, Benjamin W. Sears MD, John Andre BS, Pietro Tonino MD, Guido Marra MD

Patients undergoing arthroscopic shoulder surgery in the beach chair position may be at increased risk for serious neurocognitive complications as a result of cerebral ischemia.

Foreign Body Reaction to Acellular Dermal Matrix Allograft in Biologic Glenoid Resurfacing

Surena Namdari MD, MSc, Christopher Melnic MD, G. Russell Huffman MD, MPH

Biologic glenoid resurfacing is a treatment option for young patients with glenohumeral arthritis. An optimal synthetic graft for glenoid resurfacing should allow repopulation with host cells, be durable enough to tolerate suture fixation and forces across the joint, and present no host inflammatory response. We report two cases of giant cell reaction to GraftJacketafter biologic glenoid resurfacing.
