Role of Tranexamic Acid in Arthroscopic Osteocapsular Release of the Elbow for Degenerative Arthritis.

Background: Minimizing intra-articular bleeding and swelling is crucial in preventing the development of stiffness around the elbow. Tranexamic acid (TXA) has been shown to be an effective adjunct in reducing perioperative bleeding after surgery.

Purpose: To determine the effect of intravenous (IV) TXA on postoperative drain tube output in arthroscopic osteocapsular release of the elbow for primary degenerative arthritis.

Isolated Proximal Radioulnar Joint Instability: Anatomy, Clinical Presentation, and Current Treatment Options.

Isolated proximal radioulnar joint instability is an uncommon and often challenging problem that may manifest as recurrent instability of the proximal aspect of the radius, usually during forearm pronation and supination. Instability is due to deficiency of the stabilizing structures around the proximal aspect of the radius, and biomechanical studies have highlighted the importance of the annular ligament and the interosseous membrane in both transverse and longitudinal plane stability. Reconstruction of the stabilizing structures around the radial head often is indicated in cases of recurrent instability and includes joint-preserving procedures such as annular ligament reconstruction, proximal ulnar osteotomy, and interosseous membrane reconstruction.

Anteromedial Release for Posttraumatic Flexion-pronation Contracture of the Wrist: Surgical Technique.

Wrist stiffness can be a complication of trauma. A small percentage of patients fail to improve with nonoperative management and require operative intervention to regain range of motion and function. These group of patients can present with a soft tissue flexion-pronation contracture, which is hypothesized to be caused by capsular contraction of the distal radioulna joint, musculotendinous contracture of the flexor carpi ulnaris, contracture of the volar ulnar carpal ligaments and of the pronator quadratus muscle.

Magnetic resonance imaging based coracoid morphology and its associations with subscapularis tears: a new index.

Background: We aimed to assess the validity of magnetic resonance imaging (MRI) in assessing the subcorocoid space and determine the validity of novel sagittal plane subcorocoid space measurements.

Methods: We assessed 33 arthroscopically proven subscapularis tears with MRIs compared to 33 (instability) controls with normal subscapularis tendons. Three examiners analyzed MRIs for seven static indices of corocoid morphology, in axial and sagittal planes.

Modular neck total hip arthroplasty - a perfect storm.

Purpose: This study was aimed to highlight neck notching as a potential cause of failure in modular neck total hip arthroplasty. It aimed to identify both the combination of modular components that place patients at greatest risk of failure and the potential mechanism for failure.

Methods: This study involved a retrospective review of 301 total hip arthroplasties (THA) using Kinectiv modular neck Technology (Zimmer, Warsaw, Indiana).
