Achilles and peroneal tendon injuries in the athlete. An expert's perspective.

Peroneal tendonopathy or injuries are not common but may be troubling to the sports enthusiast. Prompt diagnosis and treatment usually result in complete recovery with conservative measures. Biodynamic orthosis with deep heel cups and a long lateral flange extension often are required for return to activity. MR imaging is helpful in difficult, persistent cases to check for ruptures. Surgery is not commonly performed but if required is usually successful in correcting the pathology. Alternative medicine may improve treatment outcomes. Biomechanical functional analysis and attention to training errors is essential in any lower extremity injury or pathology.

Achilles Tendon

Retrocalcaneal problems.

The majority of retrocalcaneal problems may be treated conservatively, using a biomechanical approach with appropriate shoe modification, padding, orthoses, and injection therapy. When appropriate indications are present, calcaneal osteotomies should be considered, despite less indication for these procedures than for simple resection of the retrocalcaneal exostoses.

New and investigative procedures for flatfoot surgery.

For those patients who need it, surgical intervention for flatfoot at an early stage affords a better chance for favorable results. Various procedures that have stood the test of time and investigative procedures are presented. It is suggested that the podiatric surgeon concentrate on tested procedures and wait for further reports on investigative procedures.

Child

Medial plantar digital proper nerve syndrome (Joplin's neuroma)--typical presentation.

Joplin's neuroma, a painful pedal neuralgia, is a benign enlargement of the medial plantar digital proper nerve. The pathology is described as a degenerative process of the nerve characterized by perineural fibrosis. This clinical entity is thought to be caused by 1) trauma, 2) biomechanical imbalances, 3) entrapment, and 4) pinch callus resulting from interphalangeal joint accessory bone. This article illustrates typical presentation of the syndrome, taking into consideration the first two etiologic factors, which have not been reported in the literature.

A biomechanical approach to running injuries.

I have introduced the concept of controlling overuse syndromes by controlling the etiology. The etiology of most overuse syndromes is biomechanical deformity of the lower extremity as well as nonadherence to sound principles of training and conditioning. It is important to realize these factors to provide for many years of injury-free athletic involvement.
