Having considered the more generalised neuromuscular and skeletal problems of childhood in the previous two books we concentrate in this book on regional disorders. The upper limb chapters describe foetal development and how this may go wrong. As always function dominates our management plans although cosmetic considerations must be borne in mind. Perinatal brachial plexus injury is analysed and a plea made for early recognition and reconstruction of both plexus lesions and peripheral nerve injuries. The lower limb chapters consider limb deficiency and deformity and how best we should manage them. Those prominent afflictions of the child s hip - dysplasia Perthes disease and epiphyseal slipping - are fully discussed. Chapters on the common conditions affecting the knee foot and ankle complete this section.
