Orthopedic aspects of child abuse.

Child abuse remains a relatively frequent cause of orthopedic injuries in infants and children, and, although the classic signs of abuse are still useful for identifying victims, more careful observation and more sophisticated diagnostic tests, such as collagen synthesis, may be required to identify less severely injured victims. Recently observed changes in injury patterns and age incidences should be considered in the evaluation of a child suspected of being a child abuse victim.

Chondrolysis after slipped capital femoral epiphysis.

Chondrolysis, or acute cartilage necrosis, is a controversial and perplexing complication of slipped capital femoral epiphysis (SCFE) in adolescents. It usually leads to deformity, pain, limping, and limitation of motion in the affected extremity. Although several theories have been proposed, no agreement has been reached as to the etiology or the pathogenesis of chondrolysis. Furthermore, no treatment program has been completely successful, and the general prognosis and natural history of this condition are not clear. An overview of the latest knowledge of the matter is presented.

Knee, lower leg, foot, and ankle disorders in children.

The literature of the past year increased our understanding of the etiology of some common lower leg disorders in children, and increased our knowledge about the results and complications of some old and new treatment methods. Histochemical and vascular studies and magnetic resonance imaging were used to study the etiology and treatment of congenital clubfoot. Results of early intervention protocols and the ilizarov method were reported. Undercorrection at primary surgery was identified as a major reason for reoperation. Excision of the coalition with interposition of fat or tendon produced good results in selected children with middle facet talocalcaneal coalition. A footprint-measuring system can differentiate among a normal foot, a flexible flatfoot, and a rigid flatfoot. Classification of metatarsus adductus was questioned, and polydacytyly of the foot was classified in detail. The treatment of leg length discrepancy and angular deformities by osteotomy, hemiepiphysiodesis, and external fixation techniques was described. Several treatments were reported for congenital pseudarthrosis of the tibia. In all, the reports of the past year offer hope for improving the results of treatment by better understanding, innovative surgical techniques, and better methods to determine timing of surgery and predicting results.

Congenital pseudarthrosis of the tibia. Long-term follow-up study.

Review of the literature reveals how difficult it is to assess the results of treatment of pseudarthrosis of the tibia. There is disagreement as to when the result can be considered final. This study reviewed the long-term results of treatment to determine if skeletal maturity could be considered the definitive end point of treatment or if the results deteriorate past skeletal maturity. In addition, the effect of neurofibromatosis on pseudarthrosis of the tibia is analyzed. Forty-one patients were reviewed. Only 25 had sufficient follow-up data to be included in this study. Eighteen of the 25 had neurofibromatosis. The results were classified according to criteria developed by Morrissy et al. At skeletal maturity, there were ten good results, three fair results, and three poor results, with nine patients having had amputation. At long-term follow-up evaluation (average 36 years; range five to 62 years), one patient with a fair result had elected amputation. About one half of the patients with neurofibromatosis required amputation. This study suggests that the results at skeletal maturity are reliable indicators of long-term results.

Post-traumatic cutaneous mucormycosis in diabetes mellitus. Short-term antifungal therapy.

Mucormycosis is infrequently encountered in the pediatric population in any of its forms (nasopharyngeal, disseminated, pulmonary, or cutaneous) and generally is associated with the immunocompromised host. We present an adolescent with poorly controlled diabetes mellitus who developed a progressive skin lesion 3 weeks after a motor vehicle accident. Rhizopus species was isolated from the lesion, and the biopsy revealed a fungal vasculopathy. Control of her diabetes, aggressive surgical intervention and a 10-day course of antifungal therapy (amphotericin B) resulted in a favorable outcome. This article illustrates the importance of considering cutaneous fungal infections, especially those in the class zygomycetes, in the diabetic patient with unusual, severe or persistent skin lesions. Early recognition is essential in order to avoid morbidity and mortality from this unusual opportunistic infection.

The pes anserinus transfer. A long-term follow-up.

We evaluated forty-eight patients (fifty knees) with pes anserinus transfer at an average of nine years after operation. There was a high incidence of anteromedial and anterolateral rotatory instability. The incidence (54 per cent) of significant roentgenographic changes at follow-up was also high. Although many patients were improved symptomatically after pes anserinus transfer, only nineteen patients (38 per cent) had no limitation of function.

Slipped capital femoral epiphysis associated with radiation therapy.

We reviewed 32 children with 41 radiation-therapy associated slipped capital femoral epiphyses (RTASCFE). Ten were from the authors' institutions and 22 from the literature. Gender distribution was equal. The age at diagnosis of the malignancy was 4.3 +/- 3.1 years; the amount of radiation was 4,240 +/- 1,445 rads. Children with RTASCFE presented younger (10.4 +/- 3.2 years) than a routine SCFE. The average symptom duration was 5 +/- 6 months. Children with RTASCFE are usually thin (median weight, 10th percentile) in contrast to children with typical SCFE, who are usually obese (<95th percentile). The majority (82%) of the slips were mild, compared to routine SCFEs (approximately 50%); 28% were bilateral. There was a positive linear relationship between the age at presentation of the SCFE and the age at diagnosis of the malignancy; there was a negative linear relationship between the age at presentation of the SCFE and the amount of radiation therapy.

Interlocking intramedullary nailing of femoral-shaft fractures in adolescents: preliminary results and complications.

Thirty-one femoral-shaft fractures in 30 patients were treated with interlocking intramedullary nails. The 19 boys and 11 girls ranged in age from 10 to 15 years (average age 12 + 3 years) at the time of injury. All fractures united, and the average leg-length discrepancy (comparing the injured to the uninjured extremity) was 0.51 cm. Two patients had overgrowth of > 2.5 cm; none had angular or rotational malunions. One patient developed asymptomatic segmental avascular necrosis of the femoral head, which was not seen on radiographs until 15 months after injury. All nails were removed at an average of 14 months after injury; no refracture or femoral neck fracture has since occurred. Intramedullary nailing is a reasonable alternative for the treatment of isolated femoral-shaft fractures in older adolescents and in younger adolescents with multiple trauma.
