Clinical and Surgical Outcomes of Shoulder Arthrodesis.

Shoulder arthrodesis is typically seen as a salvage procedure with limited functional objectives. In appropriately selected patients, it may effectively alleviate pain, provide stable motion, and offer patient function satisfaction. However, there have been few reports on the outcomes following shoulder arthrodesis.

Are Psychologic Factors Associated With Shoulder Scores After Rotator Cuff Surgery?

Background: Psychologic factors are associated with pain and disability in patients with chronic shoulder pain. Recent research regarding the association of affective psychologic factors (emotions) with patients' pain and disability outcome after surgery disagrees; and the relationship between cognitive psychologic factors (thoughts and beliefs) and outcome after surgery is unknown.

Questions/purposes: (1) Are there identifiable clusters (based on psychologic functioning measures) in patients undergoing shoulder surgery? (2) Is poorer psychologic functioning associated with worse outcome (American Shoulder and Elbow Surgeons [ASES] score) after shoulder surgery?

Methods: This prospective cohort study investigated patients undergoing shoulder surgery for rotator cuff-related shoulder pain or rotator cuff tear by one of six surgeons between January 2014 and July 2015.

Patellar eversion during total knee replacement: a prospective, randomized trial.

Background: Proponents of minimally invasive total knee arthroplasty argue that retracting rather than everting the patella results in quicker postoperative recovery and improved function. We aimed to investigate this in patients undergoing knee arthroplasty through a standard medial parapatellar approach.

Methods: In a prospective randomized double-blinded study, sixty-eight patients undergoing total knee arthroplasty through a standard medial parapatellar approach were assigned to either retraction or eversion of the patella.

A biomechanical comparison of locking plate and locking nail implants used for fractures of the proximal humerus.

The aim of this study was to determine the biomechanical behavior of 2 different implants used in the fixation of proximal humeral fractures. The 2 implants in this study are specifically designed for the fixation of proximal humeral fractures, and both are based on the concept of fixed-angle locking screws. A reproducible 3-part fracture was created in paired human cadaveric bone and then fixed via the locking screw implants.

A comparison of conventional versus locking plates in intraarticular calcaneus fractures: a biomechanical study in human cadavers.

Background: Internal fixation of displaced intraarticular calcaneal fractures in patients older than 50 years remains controversial. This is, in many cases, due to fear of loss of fixation and the risk of implant failure in osteoporotic bone. It is the objective of this study to compare the fixation strength obtained using calcaneal plates with and without locking screws, in the fixation of osteoporotic cadaveric intraarticular calcaneal fractures.
