The flexor carpi radialis brevis (FCRB) muscle, considered a rare anomaly, is not well known among orthopedic surgeons. The indications for volar locking plates to treat distal radius fractures have recently expanded, and, as a result, encounters with the FCRB are becoming more common. However, few studies have described how to retract an FCRB. Here, we describe seven of 264 patients with FCRB who underwent surgery for distal radius fractures. In one case, the retracted FCRB interfered with the internal fixation. The presented cases demonstrate that the radial retraction of an FCRB with a large muscle belly enables favorable exposure of the distal radius.

Background: Usually, patients with hand, wrist/forearm disorders report musculoskeletal complaints in the shoulder. Although, role of scapula is fundamental for movement and functional stability across the upper limb kinetic chain; however, there are no systematic reviews and meta-analyses that have analyzed the effect of scapular exercises in these patients.

Purpose: This study aimed to determine the effectiveness of a scapular exercise program on functional outcomes in patients with hand, wrist or elbow disorders.

Background: Non-invasiveness and comfort are crucial in the conservative management of distal radius and scaphoid fractures. While fiberglass casts are standard, three-dimensional (3D)-printed orthoses offer a promising alternative.

Purpose: To compare patient experiences, safety perceptions, and satisfaction between a 3D orthosis and fiberglass cast for distal radius or scaphoid fractures.

Background: Rupture of extensor pollicis longus tendon (EPL) is a known complication following a distal radius fracture (DRF). Although the precise mechanisms behind these ruptures remain unclear, vascular impairment is thought to play a significant role. Additionally, the impact of an EPL rupture on microstructure of the tendon and muscle is not well understood, but such information could be important in guiding treatment strategies.

There are many good reasons to improve the anatomy of a distal radius fracture, such as early return to function and avoidance of sigmoid notch incongruity or ulnocarpal impaction. It is often feared by patients, and portrayed by some authors of scientific articles and medicolegal reports, that a fracture of the distal radius has a propensity to cause symptomatic osteoarthritis. This article examines some of the current evidence and shares the authors' experience.

A retrospective analysis of quality of life domains impacted by distal radius fracture and ulnar neuropathy.

Faculty of Health Sciences, Western University, London, Ontario, Canada; Roth McFarlane Hand and Upper Limb Centre, St. Joseph's Hospital, London, Ontario, Canada; School of Rehabilitation Science, McMaster University, Hamilton, Ontario, Canada.

Background: Distal radius fractures (DRF) and ulnar neuropathy (UNE) present with reduced motor function, restricted range of motion, pain, and reduced grip strength that may lead to similar treatment approaches. With rapid and insidious onset for DRF and UNE, respectively, the contextual factors impacting an individuals' experience with the condition can vary.

Purpose: The aim of this secondary analysis is to compare ratings of quality of life (QoL) domains prior to treatment and 3 months post treatment for DRF and UNE.
