Seventy-four children with obstetric brachial plexus palsy registered with the British Paediatric Surveillance Unit were prospectively followed for a minimum of 2 years. Thirty-nine (52.7%) spontaneously recovered to normal or nearly normal levels and a further 29 (39.3%) regained good function in the upper limb. The most important secondary deformity involved the gleno-humeral joint and 20 patients (27%) needed surgical correction. Two more children await operation for shoulder deformity. The brachial plexus was explored in nine patients (12.2%) and repaired in seven.
Both clinical and radiological changes had various and no uniform localization. Poor correlation was found between symptoms and radiological lesions. Survival rates in children with AL were 95.8% at 1 year, 89.6% at 3 years, 85.8% at 5 years, and 83.4% at 10 and at 13 years. Radiographic abnormalities (P = 0.400), type of leukemia (P = 0.291), sex (P = 0.245), and white blood cell count at presentation (P = 0.877) were not prognostic factors. The presence of multiple bone lesions did not affect the survival rate (P=0.632). As early diagnosis significantly decreases morbidity and mortality of AL, the orthopaedist should suspect AL in any child with unexplained persistent skeletal pain or radiographic alterations. Accurate history, general physical examination, and complete blood cell count tests should address the suspicion, which is confirmed by a peripheral and/or iliac crest bone marrow biopsy.
Fifty-six patients with 72 duplicated toes were analysed. Postaxial duplication accounted for 79%, and the most common anatomical pattern was duplication of the proximal phalanx with a wide metatarsal head. Forty-two patients with 55 duplications were clinically and radiographically evaluated at long-term follow-up (mean 22.5 years). Results were satisfactory in 91% of the patients. Poor results were often associated with preaxial polydactyly because of persistent hallux varus. Surgical treatment is usually straightforward but must be individualized, and some anatomical and surgical details should be considered to obtain a better result.
Seventy-three children with slow recovery after obstetric lesion of the brachial plexus (biceps function returning after 3 months of age) and with relatively favourable neurophysiological investigation were followed until a mean age of 4.3 years. Predictions for C6 and C7 were confirmed in 92% and 96% of the cases, respectively. Predictions for C5 were confirmed in a smaller proportion of cases (78%). The inability to record nerve action potentials for C5, and the high frequency of secondary shoulder pathology are reasons for this. In all, 33 of the 73 children came to operation for medial rotation contracture (11) or posterior subluxation/dislocation (21); there was one case operated for inferior contracture.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
