Thompson and Hamilton type IV Freiberg's disease with involvement of multiple epiphyses of both feet.

A 17-year-old boy reported left second and third toe pain after axial loading injury to his left foot. Radiographs showed collapse of the second metatarsal heads and epiphysial irregularities of the fifth metatarsal heads and the condyle of the proximal phalanx of the hallux of both feet. The patient was diagnosed to have Thompson and Hamilton type IV Freiberg's disease. He was screened for epiphysial dysplasia of the other sites. He had on and off bilateral hip and knee pain. Radiographs showed bilateral symmetrical epiphysial abnormalities with morphological change as focal concavity in bilateral femoral heads and fragmentation of the patellar articular surface with preservation of the patellofemoral joint space.

Enfermedad de Charcot-Marie-Tooth: consideraciones ortopédicas / Charcot-Marie-Tooth syndrome: orthopaedic considerations

La enfermedad de Charcot-Marie-Tooth es una enfermedad heredodegenerativa del sistema nervioso periférico. La alteración es progresiva, y provoca deformidades en pies y manos. La musculatura de la pierna y el pie es la más afectada. La forma de presentación es muy diversa debido a que la afectación muscular es diferente en cada paciente. El pie cavo-varo es la forma de presentación habitual. El tratamiento conservador consiste en férulas correctoras, plantillas y rehabilitación. La indicación quirúrgica se plantea cuando fracasa el tratamiento conservador. La deformidad y el dolor son los problemas principales. En las deformidades flexibles se plantean cirugías para preservar las articulaciones. Los dedos en garra se tratarán con transferencias tendinosas o artroplastias. La deformidad en garra del dedo gordo se produce por el descenso del primer metatarsiano y la hiperactividad del músculo extensor hallucis longus. El tratamiento de esta deformidad del dedo gordo se realiza mediante la técnica de Jones. El descenso del primer metatarsiano necesitará una osteotomía dorsiflexora en la base del primer metatarsiano. Para el varo de retropié se utiliza la osteotomía valguizante de calcáneo. La retracción de la fascia plantar, gastrocnemio y Aquiles se trata con elongación de las estructuras retraídas. Cuando las deformidades son rígidas, será necesario realizar una artrodesis de las articulaciones afectadas. La artrodesis más utilizada es la triple artrodesis (AU)

Charcot-Marie-Tooth disease is a degenerative hereditary disease of the peripheral nervous system. The change is progressive and causes deformities in the feet and hands. The musculature of the leg and foot are most affected. The form of presentation is very diverse owing to the muscle involvement being different in each patient. The high-arched foot is the most common form of presentation. Conservative treatment consists of correction splints, insoles and rehabilitation. Surgery may be indicated when conservative treatment fails. The deformity and pain are the main problems. In flexion deformities surgery is indicated to conserve the joints. Claw hammer toes should be treated with tendon transfers and arthroplasty. The claw deformity in the big toe is caused by the descent of the first metatarsal and hyperactivity of the hallucis longus extensor muscle. The Jones technique is performed as treatment for this deformity of the big toe. The descent of the first metatarsal requires a dorsiflexion osteotomy in the base of the first metatarsal. For the hind foot varus a calcaneal vagus osteotomy is used. The tightening of the plantar fascia, gastrocnemius and Achilles is treated with an extension of the muscle contractures. When the deformities are rigid, it will be necessary to perform an arthrodesis of the affected joints. The arthrodesis most used is the triple arthrodesis (AU)

Skewfoot.

Skewfoot is a rare deformity characterized by forefoot adduction and hindfoot valgus. Its etiology and natural history are unknown, although congenital and syndromic forms are observed. Currently, there is no consent about the treatment of skewfoot. Due to its potential resistance to the effects of therapy, it must be differentiated from other, more common deformities. Treatment involves conservative and, most often, operative measures.

Elongation of brachymetatarsy with ceramic implant: a roentgenographic evaluation of its utility.

The metatarsal bone was elongated by intercalary implantation of a single-crystal alumina ceramic in 7 patients with brachymetatarsy. The implants were encased with new bone 24 months after surgery and resulted in 5.2 to 9.2 mm elongation of the metatarsal bone. The response of the bone to the ceramic implant was observed roentgenographically. No resorption or pseudoarthrosis of the bones, nor loosening or breakage of the implants, were observed. The alumina ceramic implant proved to be a useful substitute for a bone graft, because of its biocompatibility and strength.
