The purpose of this study was to evaluate the effectiveness of the new Double-V osteotomy of the first metatarsophalangeal joint (1MPJ) in patients with hallux limitus (HL).A study of 66 patients was performed, 33 patients were treated Cheilectomy and 33 were treated Double-V. All patients underwent an assessment of the passive mobility of the 1MPJ before the procedure, reevaluated 12 months la...

Abnormal foot mechanics is the most common cause of hallux abducto valgus. To date no quantitative data regarding the relationship between abnormal foot mechanics and the degree of hallux abducto valgus has been presented. An outline of the abnormal foot mechanics responsible for hallux abducto valgus is described along with a technique for measuring the extent of abnormal function. A common in...

The modified Valenti procedure for the treatment of hallux limitus offers the advantage of being technically easy to perform, allows for the intrinsic musculature to remain intact for stability, and is a viable alternative for patients who are not candidates for implant arthroplasty. The operation involves resection of the dorsal one third to one half of the metatarsal head and the dorsum of th...

The effects of hallux limitus on plantar foot pressure and foot kinematics have received limited attention in the literature. Therefore, a study was conducted to assess the effects of limited first metatarsophalangeal joint mobility on plantar foot pressure. It was equally important to identify detection criteria based on plantar pressures and metatarsophalangeal joint kinematics, enabling diff...

Hallux rigidus (HR) is the limitation of motion at the first metatarsophalangeal (MTP) joint, most commonly secondary to degenerative arthritis. Surgical options for treating HR include 2 general categories: joint salvage and joint destruction. A hybrid of techniques from the 2 categories has emerged: cartilage resurfacing, interpositional arthroplasty, and arthrodiastasis. These procedures add...

We report a case of a 65-year-old man with a painful nonunion of the first metatarsophalangeal joint (MTPJ). It is one of the main severe complications of this surgery. Its prevalence is described between 5% and 10% across different operative techniques. The implantation of hemicup-prosthesis has been successfully used for the hallux rigidus treatment with very promising results. In our case re...
