Objectives: This study aimed to examine the footwear alterations following first metatarsophalangeal (MTP1) joint arthrodesis. Methods: A retrospective review was performed on 37 (42 feet) patients who underwent MTP1 arthrodesis between January 2014 and 2019 in our institution. Functional outcomes were assessed with American Orthopedic Foot Ankle Society Hallux metatarsophalangeal–interphalange...

Gait is influenced by many factors, but one of the most prominent ones shoe heel height. Optical motion tracking technology widely used to analyze high-heeled gait, it normally involves several high-quality cameras and licensed software, so clinics researchers with low budgets cannot afford them. This article presents a simple, effective technique measure rotation angles on sagittal plane ankle...

BACKGROUND The aim of this cadaveric study was to assess the technical feasibility of inserting a novel interpositional pyrolytic carbon coated implant in the first MTP joint, determine the best surgical procedure for the implantation, and evaluate the dynamic behavior of the joint after surgery. METHODS The marble implant was inserted in the first metatarsophalangeal joint of five pairs of c...

We report the reconstruction of two cases of floating thumb by transplanting the distal two-thirds of the fourth metatarsal. Opponensplasty was performed after six months and resulted in satisfactory morphological and functional results. The metatarsal defect was filled by a full-thickness iliac bone graft including the apophysis. This prevented shortening of the fourth toe and formed a new met...

Background To describe the clinical and magnetic resonance imaging findings of ganglion cysts with effusion in the flexor hallucis longus tendon sheath around the hallux to evaluate their origin. Methods Patients with recurrent or painful ganglion cysts around the hallux with effusion in the flexor hallucis longus tendon sheath who underwent surgical treatment at St. Vincent's Hospital from F...

BACKGROUND Hallux valgus (HV) is a very common deformity of the first metatarsophalangeal joint that often requires surgical correction. However, the association between structural HV deformity and related foot pain and disability is unclear. Furthermore, no previous studies have investigated concerns about appearance and difficulty with footwear in a population with HV not seeking surgical cor...

The draft genome (57.7% GC, 7,647,882 bp) of the novel thermophilic cyanobacterium MTP1 was determined by metagenomics of an enrichment culture. The genome shows that it is in the family Oscillatoriales and encodes multiple heavy metal resistances as well as the capacity to make exopolysaccharides.

A case of traumatic hallux varus due to avulsion fracture of the lateral side of the base of proximal phalanx was reported. The lateral instability of the first metatarsophalangeal joint was believed to be due to the disruption of adductor hallucis function. It was successfully managed by minimally invasive extensor hallucis brevis tenodesis.
