Microvascular toe interphalangeal joint transfer can serve as a means of autogenous digit proximal interphalangeal joint (PIPJ) arthroplasty. Among surgical options for treating dysfunctional, absent, or destroyed PIPJs, free toe joint transfer is the most technically challenging and carries the greatest donor site cost to patients. Despite drawbacks, free toe joint transfer is a valuable tool with considerable advantages over conventional arthroplasty in the appropriate clinical setting. Particular advantages include lifelong durability, coronal plane stability, low infection risk, and growth potential in skeletally immature patients. This technique requires a balanced assessment of the risk-to-benefit ratio for each patient.

Continuous relative phase (CRP) quantifies coordination for cyclic motions as the difference in the phase portrait locations between its constituent coordinates and has been widely used in populations with neuromuscular impairments. Continuous analyses, like statistical parameter mapping (SPM), provide greater resolution than traditional techniques that first compress CRP across a section of the cycle to a single point, like mean average relative phase (MARP). However, both analyses neglect the effect of intermediate event timing (e.

Gait disturbance is one of the most common symptoms in patients with Parkinson's disease (PD) that is closely associated with poor clinical outcomes. Recently, video-based human pose estimation (HPE) technology has attracted attention as a cheaper and simpler method for performing gait analysis than marker-based 3D motion capture systems. However, it remains unclear whether video-based HPE is a feasible method for measuring temporospatial and kinematic gait parameters in patients with PD and how this function varies with camera position.

Background: This study aimed to investigate the safety and reliability of using bioabsorbable screws for the fixation of chevron osteotomy in the treatment of hallux valgus (HV) deformity.
Methods: Clinical cases of chevron osteotomy in the treatment of HV deformities in our hospital between December 2018 and August 2022 were retrospectively summarised to compare preoperative imaging indices with those at the final follow-up session, including the hallux valgus angle (HVA), intermetatarsal angle (IMA) and tibial sesamoid position (TSP). The American Orthopaedic Foot and Ankle Society (AOFAS) hallux metatarsophalangeal-interphalangeal scale, short-form health survey questionnaire (SF-36) and European Foot and Ankle Society (EFAS) scale were used to assess therapeutic efficacy.
Lateral Polydactyly of the Foot: Surgical Outcomes Based on a New Classification.
Plast Reconstr Surg Glob Open
January 2025
From the Department of Orthopedic Surgery, Japanese Red Cross, Aichi Medical Center, Nagoya Daiichi Hospital, Nagoya, Aichi, Japan.
Background: The objective of this study was to propose a novel classification for lateral polydactyly of the foot that integrates both visual appearance and radiographic findings and to delineate surgical techniques and their outcomes based on this classification.
Methods: This study enrolled 148 feet from 126 patients who underwent initial surgery at our hospital between January 2009 and July 2021. The new classification system was derived from visual appearance according to the Hirase classification and radiological bifurcation level (D: distal or middle phalanx, P: proximal phalanx, and M: metatarsal).

The perioperative surgical home (PSH) is a care delivery model designed to improve the perioperative and long-term outcomes of patients undergoing surgery by promoting holistic care and seamless cooperation between different services and subspecialties. An aging population and increased surgical complexity have led to renewed interest in PSH models.
