Article Synopsis
  • The study investigates two methods, asymmetric reaming (AR) and posteriorly augmented glenoid (PAG) components, to correct posterior glenoid wear and retroversion in shoulder arthroplasty patients.* -
  • Results show that both approaches improve glenoid version, with PAG components generally providing greater correction but also posing a higher risk for central peg perforation, particularly with the 5 mm augmentation.* -
  • Overall, both methods effectively re-center the humeral head, but further long-term studies are necessary to evaluate the clinical significance of these outcomes.*

In a systematic review, we critically examined and synthesized the results of individual studies on reverse shoulder arthroplasty (RSA) with latissimus dorsi tendon transfer. Two electronic databases were searched. For each included study, 2 reviewers evaluated the quality of its methods and retrieved data.

Metal allergy is an uncommon and poorly understood cause of failure of orthopedic implants. To the authors' knowledge, there have been no reports of the management of shoulder arthroplasty patients with metal allergy. The authors present their experience with the diagnosis and management of patients with metal allergy.

Background: Heterotopic ossification (HO) around shoulder arthroplasty is a frequent finding with unclear clinical relevance. This study evaluated the incidence, relevance, and predisposing factors of HO in the long head of the triceps tendon after reverse shoulder arthroplasty.

Methods: Retrospective chart review was conducted to identify patients who had a reverse shoulder arthroplasty performed between 2008 and 2012.

Background: The safe and effective acquisition of microvascular surgical skills is a challenge for any residency program. Variable clinical exposure to microsurgery, premiums on operating room efficiency, and a steep learning curve make these skills difficult to acquire through clinical experience alone. The purpose of this study was to determine the effectiveness of a training curriculum on the development of microvascular surgical skills in our orthopaedic residents.

The median nerve provides sensory innervation to the radial aspect of the hand, including the palm, thumb, index, long, and half of the ring fingers. It provides motor innervation to most of the volar forearm musculature and, importantly, to m ost of thenar musculature. The main goal of median nerve reconstructive procedures is to restore thumb opposition.

Background: Gait adaptations in persons with anterior cruciate ligament (ACL) injuries have been debated. Many studies examine high speed, 3-dimensional video gait analysis to compare knee joint torques during simulated activities of daily living.

Methods: We performed a systematic review of the literature for published clinical papers that reported sagittal plane knee joint kinetics in ACL deficient or reconstructed individuals.

Thermosetting polymers are attractive candidates for biomedical applications as noninvasive therapeutic delivery vehicles. In the present study, the feasibility of developing a neutral physiological temperature setting injectable formulation based on chitosan and an inorganic phosphate salt have been demonstrated. The in situ gelling system was developed by adding different concentrations of ammonium hydrogen phosphate (AHP) to chitosan solution.
