Olecranon bursitis (OB) involves fluid accumulation in the bursa, with common causes being trauma and preexisting conditions. Its incidence is difficult to quantify, and risk factors such as diabetes, obesity, and male gender are frequently noted. Hyperlipidemia has been linked to musculoskeletal disorders, but its role as a risk factor for OB remains unexplored.

J Hand Ther

December 2024

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.

Purpose: Distal radius fractures (DRF) that occur from a fall from level ground are considered fragility fractures and may be the first indication that someone has compromised bone mineral density and is at risk of having osteoporosis. Women at about 50 years of age experience a dramatic increase risk of these fractures. Rehabilitation after DRF focuses on restoring range of motion and strength in the wrist, but rarely address future bone health concerns.

Article Synopsis
  • The study focused on the effectiveness of percutaneous synovial biopsy (PSB) and joint aspiration in diagnosing prosthetic infections in patients undergoing revision shoulder arthroplasty, comparing their results to those from open culture biopsies.
  • Conducted across four medical centers with 69 patients, the research found that 19% tested positive for infection with PSB, while 23% tested positive through open biopsy, showing that PSB had lower sensitivity but fairly good specificity.
  • Results indicated that while PSB is somewhat reliable, its diagnostic accuracy is limited, highlighted by a 37% sensitivity rate and 81% specificity, and the study also explored how the biopsy location within the shoulder might relate to infection

Article Synopsis
  • This study aimed to create a machine learning algorithm that would help estimate the likelihood of recurrence after an arthroscopic Bankart repair (ABR) for shoulder instability.
  • The researchers analyzed data from 14 studies involving 5,591 patients and identified risk factors for recurrence, finding that certain factors like age and type of sport increased risk, while a single dislocation reduced it.
  • However, the machine learning model struggled to accurately predict recurrence rates due to inconsistent data across studies, highlighting the need for better data standardization in future research.

Glenoid implants used in anatomic total shoulder arthroplasties typically incorporate peripheral pegs as a design feature to support eccentric loads. These peripheral pegs and the implant-cement-bone interface undergo substantial cyclic tensile-compressive loads during normal activity. Therefore, these pegs are of interest in translating the micromechanics of local implant fixation failure to the biomechanics of gross anatomic failure of the glenoid implant after total shoulder arthroplasty.

Background: Following the repair of a mixed peripheral nerve, functional recovery requires successful nerve regeneration across the repair site and, eventually, reinnervation of distal targets. Reliably determining a failing nerve repair so that revision may be performed before irreversible muscle atrophy remains a challenge in peripheral nerve surgery. This study aimed to ascertain whether any commonly used clinical examination tests during surveillance after nerve repair can detect a failing repair and prompt earlier salvage intervention.

Despite significant advancements in flexor tendon repair techniques and rehabilitation strategies, achieving complete restoration of digital motion remains a formidable challenge. The most prevalent complications associated with tendon repair are the development of tendon adhesions and joint contractures. Left unaddressed, these complications can further lead to secondary pathomechanical changes, resulting in fixed deformities significantly affecting hand function.
