The authors differentiate benign rheumatoid nodules from similar subcutaneous lesions based on location and pathologic characteristics. Although many of these lesions spontaneously resolve, recurrence rates may be high. Various therapeutic modalities are therefore suggested. An illustrative case study is presented.
The treatment of pediatric deformities is relatively common in the typical foot and ankle practice. Talipes calcaneovalgus deformity represents one of the more prevalent deformities. This postural deformity, which is present at birth, is characterized by marked dorsiflexion and valgus position of the foot in relation to the leg. It is essential that an accurate diagnosis is established early and conservative treatment instituted. In most cases, the deformity is highly responsive to conservative therapy consisting of manipulation and casting. Deformity not identified at birth or soon thereafter, or residual deformity treated later in life, presents a greater challenge to the physician. This paper is intended to provide an overview of the deformity of calcaneovalgus including a discussion of etiology, incidence, clinical and radiographic manifestations, differential diagnosis, and recommended treatment. The authors present an unusual case of residual talipes calcaneovalgus left untreated since birth and the approach to management.
The authors present an interesting approach to lateral ankle stabilization using the peroneus longus tendon. The more commonly utilized procedures for instability of the ankle complex, rationale for use of the peroneus longus tendon, and the details of the split peroneus longus lateral ankle stabilization procedure are presented. When evaluating patients with lateral ankle joint instability, the subtalar joint (STJ) complex needs to be assessed. In addition, the role of STJ instability and its relationship to lateral ankle joint instability are discussed.
Plantar fibromas are a disease entity that are encountered by all foot surgeons. When a tentative diagnosis is made, aggressive surgical resection of the mass and the plantar fascia is necessary to prevent recurrence. Presented in this paper is a review of the literature and clinical illustrations of recurrent plantar fibromatosis with long-term follow-up.
