A Clinicoradiological and Functional Evaluation of Lapidus Surgery for Moderate to Severe Bunion Deformity Shows Excellent Stable Correction and High Long-Term Patient Satisfaction.

Lapidus surgery involving arthrodesis of the first metatarsocuneiform (MTC) joint is an effective procedure for the correction of moderate to severe hallux valgus. The aim of this study was to collect and analyze radiographic data from our institution and determine the extent of first metatarsal shortening associated with the Lapidus procedure. A total of 53 patients (54 feet) who underwent arthrodesis of the first MTC joint combined with modified McBride bunionectomy for correction of moderate to severe hallux valgus deformity, between 2010 and 2015 were included in this study.

Effects of alcohol injection in rat sciatic nerve as a model for Morton's neuroma treatment.

Background: Previous studies have shown that the injection of dehydrated alcohol has been successful for the treatment of Morton's neuroma in the foot. In this study, we determined the cellular effect of injection of alcohol into and around the sciatic nerve of rats and measured the extent of cell necrosis and/or any associated histologic or inflammatory changes.

Methods: Twenty-two male (~375 g) Wistar rats were randomized into 2 groups each receiving alcohol injections into or around the sciatic nerve after nerve exposure under sterile technique.

The use of intramedullary nails in tibiotalocalcaneal arthrodesis.

Tibiotalocalcaneal arthrodesis is a salvage procedure undertaken for hindfoot problems that affect both the ankle and subtalar joints (eg, two-joint arthritis, severe acute trauma, osteonecrosis of the talus, severe malalignment deformities, significant hindfoot bone loss). Methods of achieving fusion include Steinmann pins, screws, plates, external fixators, and retrograde intramedullary nailing. Retrograde intramedullary nailing provides a load-sharing fixation device with superior biomechanical properties and is an excellent choice for use in tibiotalocalcaneal arthrodesis.

Regulation of bone mass by mechanical loading: microarchitecture and genetics.

For decades, the processes that couple bone architecture and mass to function have been investigated and characterized. It is well known, and now well accepted, that increases in exercise and loading of bone are associated with increased bone mass, and that disuse induces osteopenia. However, the mechanisms by which disuse leads to bone loss remain poorly understood, even in the 21st century.

Use of computer-assisted learning module to achieve ACGME competencies in orthopaedic foot and ankle surgery.

The Accreditation Council for Graduate Medical Education (ACGME) has charged academic institutions with finding methods to assess learning in specific areas of resident education. Computer-assisted education offers a reliable mode for teaching residents important information and skills. The CD-ROM "Fundamentals of Orthopaedic Foot Care," produced by the American Academy of Orthopaedic Surgeons, was tested as a tool to provide nonoperative foot and ankle care education for a group of orthopaedic residents (N = 14) and a group of family practice residents (N = 11).
