Lateral ankle sprains: a comprehensive review: part 1: etiology, pathoanatomy, histopathogenesis, and diagnosis.

Ankle sprains are among the most common injuries sustained by athletes and seen by sports medicine physicians. Despite their prevalence in society, ankle sprains still remain a difficult diagnostic and therapeutic challenge in the athlete, as well as in society in general. The purpose of this section of our two-part study is to review scope of the problem, the anatomy and biomechanics of the lateral ankle ligaments, review the pathoanatomical correlates of lateral ankle sprains, the histopathogenesis of ligament healing, and define the mechanisms of injury to understand the basis of our diagnostic approach to the patient with this common acute and chronic injury. We extensively review the diagnostic evaluation including historical information and physical examination, as well as options for supplementary radiographic examination. We further discuss the differential diagnosis of the patient with recurrent instability symptoms. This will also serve as the foundation for part two of our study, which is to understand the rationale for our treatment approach for this common problem.

Lateral ankle sprains: a comprehensive review part 2: treatment and rehabilitation with an emphasis on the athlete.

This is the second part of a two-part comprehensive review of lateral ankle sprains. In the first part of our review, we discussed the etiology, natural history, pathoanatomy, mechanism of injury, histopathogenesis of healing, and diagnostic approach to acute and chronic lateral ligamentous ankle injuries. Conservative intervention and treatment of grade I-III and chronic, recurrent sprains of the lateral ankle ligaments and appropriate rehabilitation guidelines are the topics of this article. We review the use and benefit of different modalities and external supports and outline our five-phase intervention program of rehabilitation based on the histopathogenesis of ligament healing. We discuss the expected timing of recovery of the acute injury as well as the management of chronic, recurrent ankle sprains. Treatment of acute ankle sprains depends on the severity of the injury. Conservative therapy has been found to be uniformly effective in treating grade I and II ankle sprains. Some controversy exists regarding the appropriate treatment of grade III injuries, particularly in high-level athletes. Our belief is that the majority of these patients may also be treated well with conservative management. Other options for the management of grade III sprains will be briefly discussed at the end of this article.

Clinical results of simultaneous adjacent interdigital neurectomy in the foot.

Fifteen patients (19 feet) who underwent simultaneous surgical excision of two primary interdigital neuromas in adjacent web spaces of the foot were studied retrospectively. There were 11 female patients (73%). The average age of the patients was 54.4 years. Other causes of multiple web space tenderness were excluded prior to surgical resection of both neuromas. At an average follow-up of 68.6 months (range, 32-113 months), 10 feet (53%) had complete resolution of symptoms and six feet (31%) had minimal residual symptoms. Three feet in two patients (16%) continued to have significant pain after surgery. One sequela of the procedure was dense sensory loss of the plantar aspect of the third metatarsal head to the tip of the third toe. There was also proximal dorsal sensory loss to the second, third, and fourth toes which was a function of the type of incision used. The sensory loss did not cause disability in the patients, but did cause some awkwardness with nail care. Resection of adjacent interdigital neuromas, although rarely indicated, can be expected to provide significant pain relief in 84% of patients, which is similar to results reported for resection of a single neuroma.

A simple method for intraoperative angiography.

A simple technique for intraoperative angiography, which uses generally available, mobile equipment, is described. This method provides good quality hard-copy images for documentation, review, and verification.
