Spring ligament failure consists of lengthening or disruption of the spring ligament complex resulting in subluxation at the talonavicular joint. Spring ligament failure is commonly associated with considerable degeneration of…
Symptomatic hallux valgus associated with a first intermetatarsal angle greater than 15 degrees is typically corrected with a proximal first metatarsal osteotomy and distal soft tissue procedure when nonoperative treatment…
Rheumatoid arthritis is an inflammatory condition of synovial joints that usually presents as a symmetric polyarthropathy. Ninety percent of patients with chronic rheumatoid arthritis have involvement of the foot; the…
Ankle distraction arthroplasty is a new technique for the treatment of ankle arthritis in younger patients who wish to defer ankle arthrodesis or ankle replacement. Distraction arthroplasty is based on…
The posterior tibial tendon undergoes tearing and degeneration, and as it fails, the foot falls into a planovalgus configuration. Posterior tibial tendon dysfunction (PTTD) is the most common cause of…
The first reports of a distal metatarsal osteotomy date back to Reverdin, who described in 1881 a subcapital closing wedge osteotomy for the correction of hallux valgus deformity. The chevron…
Fracture through the midfoot in the neuropathic patient may accompany minor or incidental trauma and if unchecked may lead to severe deformity or “rocker bottom” foot deformity. This chapter demonstrates…
Deltoid ligament deficiency is present when both the deep and superficial components of the medial collateral ligament complex of the ankle are ruptured or are insufficient. Deltoid ligament deficiency may…
Ankle arthritis is characterized by loss of joint cartilage and joint narrowing. Primary ankle arthritis is relatively rare; most commonly, ankle arthritis is posttraumatic in origin. Inflammatory arthritides may also…
Severe rigid planovalgus foot deformity may be a result of multiple underlying causes. In long-standing rigid hindfoot valgus deformities, the lateral skin and soft tissues may become severely contracted. In…
