The entrapment theory is the most commonly accepted theory concerning the development of interdigital neuroma; it incriminates the deep transverse metatarsal ligament as the major causative factor of the condition. This report presents a patient with interdigital neuroma in the second intermetatarsal space, which was strongly suspected to be caused by the metatarsophalangeal joint instability d...

The ostrich is a highly cursorial bipedal land animal with a permanently elevated metatarsophalangeal joint supported by only two toes. Although locomotor kinematics in walking and running ostriches have been examined, these studies have been largely limited to above the metatarsophalangeal joint. In this study, kinematic data of all major toe joints were collected from gaits with double suppor...

BACKGROUND Currently, arthrodesis is the most commonly performed surgical procedure for the treatment of severe arthritis of the first metatarsophalangeal joint. The objective of this study was to compare the long-term clinical and radiographic outcomes of a metallic hemiarthroplasty with those of arthrodesis for the treatment of this condition. METHODS A series of patients with osteoarthriti...

An intra-articular ligament of the first metatarsophalangeal joint (MTPJ) has been observed by the authors during dissection for hallux valgus and hallux rigidus corrective surgery over a number of years. The enigmatic incidence and role of this structure prompted further investigation. A literature review was conducted across several scientific databases using the search terms “first metatarso...

OBJECTIVE To evaluate the preliminary results from the METIS-Newdeal(®) metatarsophalangeal prosthesis for treating hallux rigidus grade III/IV. METHODS This was a prospective study on eight metatarsophalangeal prostheses that were placed in six patients between November 2007 and July 2009. The patients' mean age was 55 years and the mean follow-up after the surgery was 50 weeks. The results ...

BACKGROUND Visual estimation (VE) and goniometric measurement (GM) are commonly used to assess first metatarsophalangeal joint dorsiflexion. The purposes of this study were to determine the intrarater and interrater reliability of VE and GM and to establish whether reliability was influenced by the experience of the examiner. METHODS Ten experienced and ten inexperienced examiners evaluated t...
