Modified Endoscopic Distal Soft Tissue Procedure (mEDSTP) and Arthroscopic Lapidus Arthrodesis for Correction of Severe Hallux Valgus.

Hallux valgus is one of the most common forefoot deformities faced by foot and ankle surgeons. Symptomatic deformity usually needs surgical correction. Endoscopic techniques of hallux valgus correction have been reported that are based on the same principle of the classic distal soft tissue procedure.

Arthroscopic Sesamoidectomy and Plantar Metatarsal Head Bone Shaving in Management of First Metatarsal Head Metatarsalgia After First Metatarsophalangeal Fusion.

First metatarsophalangeal arthrodesis has been used to treat end-stage arthritis of the great toe (e.g., gout, post-traumatic, infection), severe hallux valgus deformity, hallux valgus caused by neuromuscular disorders, rheumatoid forefoot deformity, primary hallux varus, and rigid plantarflexion deformities, as well as a salvage procedure for failed previous operation of the great toe.

Endoscopic Decompression of Olecranon Tophus.

The olecranon bursa is very commonly involved in tophaceous gout because of the tendency of monosodium urate crystals to deposit in superficial structures with low temperatures. Surgery is indicated if the olecranon tophus is recalcitrant to medical treatment. Open surgery requires a long incision over the tophus and may lead to wound complications.

Endoscopic Ganglionectomy of the Tarsal Tunnel: A Medial Approach.

A ganglion inside the tarsal tunnel can compress the tibial nerve, leading to posterior tarsal tunnel syndrome. Classically, the ganglion is resected with an open approach. This requires release of the flexor retinaculum and dissection around the tibial neurovascular bundle, which may induce fibrosis around the tibial nerve.

Arthroscopic Management of Synovial Osteochondromatosis of the Elbow.

Primary synovial chondromatosis is characterized by newly formed chondral or osteochondral nodules in the synovial membrane, which may detach and form loose bodies. The loose bodies can be calcified or ossified, and the condition is termed synovial osteochondromatosis. Three distinct stages can be identified in primary synovial chondromatosis : phase I is active synovitis without loose bodies, phase II shows nodular synovitis along with loose bodies, and phase III is characterized by the presence of loose bodies with the resolution of synovitis.
