A new all-suture tension band tape fixation technique for simple olecranon fractures versus conventional tension band wire fixation: a comparative biomechanics study.

Hypothesis: Simple transverse or short oblique olecranon fractures without articular comminution are classified as Mayo type IIA fractures and are typically treated with a tension band wire construct. Because of the high reoperation rates, frequently because of prominent hardware, all-suture tension band constructs have been introduced. It was the purpose to compare the biomechanical performance of conventional tension band wire fixation with a new all-suture tension band tape fixation for simple olecranon fractures.

Factors Influencing Acromial and Scapular Spine Strain after Reverse Total Shoulder Arthroplasty: A Systematic Review of Biomechanical Studies.

Background: Acromial and scapular spine fractures after reverse total shoulder arthroplasty (RTSA) can be devastating complications leading to substantial functional impairments. The purpose of this study was to review factors associated with increased acromial and scapular spine strain after RTSA from a biomechanical standpoint.

Methods: A systematic review of the literature was conducted based on PRISMA guidelines.

Prosthesis Designs and Tuberosity Fixation Techniques in Reverse Total Shoulder Arthroplasty: Influence on Tuberosity Healing in Proximal Humerus Fractures.

Reverse total shoulder arthroplasty (RTSA) is increasingly used for the treatment of complex proximal humerus fractures and fracture sequelae. In 2021, half a dozen models of fracture stems are commercially available, reflecting its growing utility for fracture management. Prosthesis designs, bone grafting and tuberosity fixation techniques have evolved to allow better and more reliable fixation of tuberosities and bony ingrowth.

Retrospective cohort study evaluating the efficacy and safety of an orthopaedic consultant-led virtual fracture clinic in an Australian level 1 trauma centre.

Background: In Australian health care, the consistent rise in demand for orthopaedic outpatient clinic services is creating marked challenges in the provision of quality care. This study investigates the efficacy and safety of a virtual fracture clinic (VFC) as an alternative model of care for the management of acute injuries and musculoskeletal conditions in the Australian public hospital setting.

Methods: A retrospective cohort study of consecutive emergency department (ED) referrals to the Department of Orthopaedic Surgery was conducted comparing outcomes prior to (November 2015-February 2017) and after (March 2017-June 2018) implementation of a VFC.

Axillary Artery Injury Associated with Proximal Humeral Fractures: Review of Long-Term Vascular, Orthopedic, and Neurologic Outcomes.

Background: Fracture and dislocation of the proximal humerus is common. It is associated with a number of vascular, neurologic, and orthopedic complications; these include brachial plexopathy and avascular necrosis (AVN) of the humeral head. These complications are rare but can potentially cause severe disability to patients; however, they remain poorly described in the literature.

What is the Best Clinical Test for Assessment of the Teres Minor in Massive Rotator Cuff Tears?

Background: Few studies define the clinical signs to evaluate the integrity of teres minor in patients with massive rotator cuff tears. CT and MRI, with or without an arthrogram, can be limited by image quality, soft tissue density, motion artifact, and interobserver reliability. Additionally, the ill-defined junction between the infraspinatus and teres minor and the larger muscle-to-tendon ratio of the teres minor can contribute to error.
