Partial wrist arthrodesis (PWA) is a salvage procedure used in advanced wrist arthritis and has traditionally been performed via an open dorsal approach. In recent years, surgeons have moved towards arthroscopic fusions to minimise soft tissue damage and preserve vascular supply, increase union rates and hasten recovery. The purpose of this study is to synthesise the current literature on the outcomes of arthroscopic PWA.

Article Synopsis
  • Distal phalangeal and interphalangeal joint injuries are common and can create significant challenges for individuals and healthcare systems, often requiring K-wire fixation to maintain alignment.
  • This study aimed to identify soft tissue and radiographic landmarks for optimal K-wire placement at the distal interphalangeal joint (DIPJ) through a retrospective analysis of 100 lateral phalangeal radiographs.
  • Results indicated a 'rule of fours' for ideal entry points during K-wire insertion, suggesting that the entry should be 4 mm from the nail plate's dorsal surface and 40% volar to the soft tissue at the DIPJ crease, enhancing safety and effectiveness without fluoroscopy.

Purpose: Clavicular nonunion is an uncommon complication with a significant impact on quality of life and can be difficult to manage. In recalcitrant cases, or situations unfavorable for take of nonvascularized grafts, vascularized osseous reconstruction may be utilized. Several donor sites for such flaps have been described, with each associated with unique benefits and drawbacks.

Introduction: Favorable short- and long-term outcomes have been reported for lumbar intervertebral total disc replacement (L-TDR). However, there is little evidence regarding the uptake of L-TDR in practice. The objective of this study was to analyze Australian-based population trends in L-TDR over the past 5 years.

Background: Chronic pain remains a significant challenge for individuals following limb amputation, with incidence of painful neuromas, phantom limb pain (PLP), and residual limb pain (RLP). Targeted muscle reinnervation (TMR) is a surgical technique designed to restore motor control information lost during amputation by redirecting residual nerves to new muscle targets. This systematic review and meta-analysis aims to compare patient-reported and functional outcomes following amputation with either TMR or standard neurological treatment (SNT).
