Spiral fracture of the distal tibia: an unusual stress fracture.

Stress fractures in athletes are frequently a misdiagnosed and poorly understood clinical entity. As a rule, their occurrence in the tibia is limited to the junction of the middle and distal third. We describe a distal spiral tibial stress fracture in a jogger and review the pathomechanics, diagnosis, and management of such lesions.

Clinical presentation of congenital convex pes valgus.

Congenital convex pes valgus, frequently termed vertical talus in past descriptions, is a malformed foot that requires early diagnosis and treatment. A brief review of clinical features and a case presentation are provided to enhance the understanding of this complex deformity. A successful treatment regimen for infants and children is described, involving manipulation and early surgical correction.

Intra-articular fractures of the calcaneus: a review.

Intra-articular fractures of the calcaneus can result in prolonged or permanent disability. The systematic approach to analysis based on anatomy, mechanism of injury, and x-ray films allows determination of the various elements of the lesion. Management is difficult because treatment is not standardized, and, even when good reduction has been achieved, long-term complications are commonplace. The authors review different types of intra-articular calcaneal fractures, various methods of treatment, and examples of possible complications.

Power staple fixation in hallux valgus surgery: a preliminary report.

The authors describe a relatively new power staple device for foot surgery. Their preliminary review has been very favorable, as studied in 40 cases of hallux valgus repair. Their discussion includes the indications, contraindications, and potential for future use in the foot.

Tuberculous arthritis: a case study and review of the literature.

Tuberculosis of the bones and joints is a rare but treatable disease. This curable condition is frequently overlooked in the differential diagnosis, and often serious cases are not diagnosed until after severe joint destruction has already taken place. The literature on tuberculosis of the bones and joints is reviewed and the incidence, etiology, pathogenesis, diagnosis, and treatment of this condition are discussed. A case history of ankle joint involvement is presented in which antibiotic treatment before clinically significant joint destruction had occurred might have prevented surgery. Tuberculous involvement should thus be considered in any patient with chronic and subacute monoarticular arthritis.

Calcaneal bone graft after enchondroma excision.

Enchondroma is a commonly encountered bone tumor in the foot, frequently necessitating excision. The calcaneus is a convenient source of bone for a bone graft, should that be required. The patient's own calcaneus offers the advantages of both cortical and cancellous bone, accessibility, dependable bone healing, and the superior osteogenic potential of autologous bone.
