Measuring Joint Flexibility in Hallux Rigidus Using a Novel First Metatarsophalangeal Joint Flexibility Jig

Hallux rigidus and osteoarthrosis of the first metatarsophalangeal joint.

Midterm Outcomes of Polyvinyl Alcohol Hydrogel Hemiarthroplasty of the First Metatarsophalangeal Joint in Advanced Hallux Rigidus.

BACKGROUND Hallux rigidus is the most common arthritic condition of the foot. A randomized clinical trial of first metatarsophalangeal (MTP) joint hemiarthroplasty with a polyvinyl alcohol (PVA) hydrogel implant (Cartiva) demonstrated pain relief and functional outcomes equivalent to first MTP arthrodesis at 2 years postoperation, with no cases of implant fragmentation, wear, or bone loss. We p...

Diagnosis and treatment of first metatarsophalangeal joint disorders. Section 2: Hallux rigidus.

Hallux rigidus is a progressive disorder of the first MTP joint, characterized by a diminished range of motion (ROM) and degenerative alterations of the joint (1–9). Because some degree of movement is generally available, the term hallux limitus (7) has been used to describe the condition, although the pathologic process is one of progressive degenerative joint disease secondary to biomechanica...

Hallux valgus and cartilage degeneration in the first metatarsophalangeal joint.

This study relates the extent of cartilage lesions within the first metatarsophalangeal joint to hallux valgus. We prospectively examined 265 first metatarsophalangeal joints of 196 patients with a mean age of 54.2 years at operation for the existence of cartilage lesions. Grade I lesions were found in 41 feet (15.5%), grade II in 82 (30.9%), grade III in 51 (19.3%), grade IV in 20 (7.5%). Only...

A finite-element analysis study of the metatarsophalangeal joint of the hallux rigidus.

Hallux rigidus was first described in 1887. Many aetiological factors have been postulated, but none has been supported by scientific evidence. We have examined the static and dynamic imbalances in the first metatarsophalangeal joint which we postulated could be the cause of this condition. We performed a finite-element analysis study on a male subject and calculated a mathematical model of the...
