Insights into the identification, prevention, and treatment of neurovascular compromise in upper extremity surgery are provided in this chapter, focusing on commonly encountered injuries susceptible to intraoperative or postoperative issues. The authors highlight the importance of knowledge of anatomy, meticulous dissection, and preparation to navigate complex surgical scenarios effectively. Furthermore, proactive approaches to managing difficult situations encountered during surgery are outlined, emphasizing timely recognition and decisive action.

Introduction: Managing open distal radius fractures (DRFs) poses challenges. While preventing surgical site infection (SSI) involves prompt antibiotic administration and thorough irrigation and debridement, the impact of urgent intervention on reducing postoperative infection rates is debated. We hypothesize that timing of surgery does not significantly affect the incidence of SSI in open DRF treated within or after 24 hours from time of injury.

Background: Corticosteroid injections are widely used for treating thumb carpometacarpal (CMC) arthritis, yet the accuracy of non-image-guided injections in expert hands is uncertain, with prior studies reporting intraarticular placement in about 60% of thumbs when performed by physicians with different levels of training. Despite their common use, there is a need to assess both the accuracy and the short-term clinical efficacy of these injections, particularly when performed without image guidance by fellowship-trained hand surgeons.

Questions/purposes: (1) What is the accuracy of thumb CMC injections performed without image guidance by fellowship-trained hand surgeons in an office setting? (2) What is the short-term efficacy of thumb CMC injections performed without image guidance?

Methods: We prospectively enrolled 33 patients with a mean ± SD age of 63 ± 12 years, 76% (25) of whom were female, with symptoms of basal joint arthritis that persisted despite conservative treatment, and we administered 1.

Purpose: The purpose of this study was to conduct a systematic review evaluating the reported complications and outcomes of bone-anchored prostheses in digit and partial hand amputees.

Methods: A literature review of primary research articles on osseointegration and bone-anchored prostheses for digit and partial amputees was performed. The Medline, Embase, Scopus, and Cochrane Library databases were queried.

Article Synopsis
  • Scaphoid nonunions are challenging for hand surgeons due to the scaphoid's poor blood supply, leading to the need for internal fixation and bone grafts for treatment.
  • Various bone graft options exist depending on the patient's condition, blood supply, and any deformities, including nonvascularized autologous grafts from different body areas and vascularized grafts for blood supply concerns.
  • The review emphasizes the importance of using bone grafts to enhance internal fixation, promote healing, and restore alignment in cases of scaphoid nonunions.
