Article Synopsis
  • Distal radius fractures are common, and this study examines how the timing of surgery (early vs. delayed) affects health care use, patient income, and recovery outcomes for patients who underwent surgery with volar locking plates.
  • The study included 106 patients over a period from 2009 to 2019, revealing that delayed surgery led to more clinic visits and therapy sessions, as well as reduced wrist mobility at the first follow-up, although this discrepancy disappeared later.
  • Higher-income patients were less likely to experience delays in surgery, indicating that access to care may be a significant factor for lower-income individuals seeking treatment.

Objectives: Finger amputations can involve different levels of injury complexity, and the success of a finger replantation is further shaped by a variety of factors, including patient characteristics, surgical technique, and postoperative rehabilitation. These variables may interact in complex ways and contribute to heterogeneity that makes it challenging to guide management for individual patients. As such, this systematic review seeks review the outcomes of isolated single digit replantation and compare patient reported outcomes following revision amputation to guide decision making.

Background: The number of surgical residents experiencing childbearing during residency training is increasing, and there is an absence of clarity with respect to parental-leave, lactation and return-to-work policies in support of residents. The aim of this review was to examine parental-leave policies during residency training in surgery and the perceptions of these policies by residents, program directors and coresidents, as described in the literature.

Methods: We performed a scoping review of the literature based on the following themes: maternity or parental-leave policies; antepartum work-restriction policies and obstetric complications; accommodations for training absences; support for, and perceptions of, maternity or parental leave during residency training; and challenges upon return to work, namely resident performance and breastfeeding.

Background: Although aromatase inhibitors are the first-line treatment in postmenopausal women with hormone receptor-positive breast cancer, there is increasing evidence that they can induce carpal tunnel syndrome and stenosing tenosynovitis. This systematic review summarizes the risk factors, incidence, and management for patients with aromatase inhibitor-induced carpal tunnel syndrome and stenosing tenosynovitis compared to tamoxifen or placebo.

Methods: A Preferred Reporting Items for Systematic Reviews and Meta-Analyses-guided systematic review of PubMed/MEDLINE, Ovid Embase, and the Cochrane Central Register of Controlled Trials was conducted (to March 19, 2020), supplemented with Google Scholar, Plastic and Reconstructive Surgery, and The Journal of Hand Surgery.

Purpose: Non-operative management of trapeziometacarpal osteoarthritis (TMOA) demonstrates only short-term symptomatic alleviation, and no approved disease modifying drugs exist to treat this condition. A key issue in these patients is that radiographic disease severity can be discordant with patient reported pain, illustrating the need to identify molecular mediators of disease. This study characterizes the biochemical profile of TMOA patients to elucidate molecular mechanisms driving TMOA progression.

Factors associated with failure of digital revascularization and replantation procedures have been well characterized, but studies have not investigated failures occurring beyond the early postoperative period. A single-centre retrospective chart review included 284 patients (434 digits) who underwent digital revascularization or replantation. Patient-, injury- and surgery-related characteristics were compared among successful procedures, digits that failed while in hospital (early failure), and initially viable digits that failed after hospital discharge (late failure).

: Nerve injuries during shoulder arthroplasty have traditionally been considered rare events, but recent electrodiagnostic studies have shown that intraoperative nerve trauma is relatively common.

: The brachial plexus and axillary and suprascapular nerves are the most commonly injured neurologic structures, with the radial and musculocutaneous nerves being less common sites of injury.

: Specific measures taken during the surgical approach, component implantation, and revision surgery may help to prevent direct nerve injury.
