Background: Combining osteotomies and soft tissue procedures is believed to reduce sesamoids in their anatomical position and maintain long-term correction when treating hallux valgus deformity. This study determines if a radiologic association exists between a radiolucent sign and a full percutaneous adductor tendon release (PATR), including a cadaveric study and a consecutive case series. Another aim was to determine the intra- and interobserver reliability of these observations.

Background: Hindfoot coronal alignment is an important factor in the assessment of patients with many different foot and ankle complaints. A number of clinical and radiographic techniques have been described to measure hindfoot coronal alignment, but none of them are widely accepted. The purpose of the present study was to assess the correlation between clinical and radiographic hindfoot alignment measures and to evaluate the reproducibility of each.

Although far less common than lateral ankle injuries, medial ankle sprains have been reported to result in significantly greater time lost and long-term disability when not diagnosed and treated accurately. Adequate diagnosis is paramount and the most important aspect is to determine whether the lesion is stable or unstable. Evidence confronting surgical versus conservative treatment in acute deltoid ligament lesions is largely anchored in the setting of ankle fractures.

A fundamental etiologic component of metatarsalgia is the repetitive loading of a locally concentrated force in the forefoot during gait. In the setting of an isolated gastrocnemius contracture, weight-bearing pressure is shifted toward the forefoot. If metatarsalgia is considered an entity more than a symptom, evaluation of gastrocnemius contracture must be a part of the physical examination, and gastrocnemius recession via the Baumann procedure alone, or in combination with other procedures, considered as an alternative treatment in an attempt to restore normal foot biomechanics.

Reports of isolated avulsion fracture of the distal phalanx of the hallux that comprise the functionality of the extensor hallucis longus tendon (EHL) are scarce and treatment for such injury has only been described in isolated single case reports. Two patients with an unstable avulsion fracture of the distal phalanx treated with reinsertion of the EHL with a Mini ThigthRope® system are presented in this paper. Two patients whom suffered an extreme plantarflexion mechanism sought attention in our clinic.

Background: Two concepts have been proposed to explain the etiology of metatarsalgia in hallux valgus patients: First, as the magnitude of hallux valgus increases, there is a mechanical overload of the lesser metatarsals. Second, increased relative lesser metatarsal length is a factor in the development of metatarsalgia. However, there is no current evidence that these structural factors lead to primary metatarsalgia.
