Biomechanical evaluation of metatarsal osteotomies for Hallux Rigidus. A cadaveric testing

Hallux rigidus

An estimated 40% of the US population have foot problems.Of all patients aged over 50 years, 2.5% report degenerative arthritis of the first metatarsophalangeal (MTP) joint, termed 'hallux rigidus'. First MTP osteoarthritis is the most common arthritic condition in the foot.Progression of great toe arthritis is associated with pain and loss of motion. Non-surgical intervention begins with shoe ...

Biomechanical consequences of first metatarsal osteotomy in treating hallux valgus.

BACKGROUND Among the numerous osteotomies for correction of hallux valgus, the modified chevron is known for its good intrinsic stability and the scarf for its large corrective potential. An intermediate design, the reversed-L osteotomy, has been developed to combine these competing biomechanical objectives. The purpose of this in vitro study was to compare the structural and local biomechanica...

A novel pyrolytic carbon implant for hallux rigidus: a cadaveric study.

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...

First Metatarsal Osteotomies for Correction of Hallux Valgus: A Finite Element Model

Short-term results after distal metatarsal osteotomies for hallux valgus, using a biodegradable Magnesium-implant

Introduction: Biodegradable implants can help to minimize the risk for hardware removal after forefoot surgery. Magnesiumalloy implants are a new material for this indication. Material and Method: 22 patients treated for symptomatic Hallux valgus deformity, by a distal metatarsal osteotomy, using a biodegradable Mg-Implant could be included in a prospective study. Results: One patient had a tra...
