Hand radiographic measurements in growth hormone deficiency before and after treatment

Hand radiographs in 10 male patients (eight white, two black) with isolated growth hormone deficiency were studied before and after treatment. The length of the second metacarpal was the most significantly depressed measurement when considered by chronologic age and responded most to treatment with human growth hormone. All patients had osteoporosis even when evaluated by height age. The bone mass improved with treatment by subperiosteal new bone apposition. Skeletal maturation was retarded with the carpals showing more severe retardation than the tubular bones and responding more dramatically to treatment. The depression in height age and carpal age was very similar, indicating that the carpal age may have the greatest correlation with height. The greater sensitivity of the carpal age deficiency of growth hormone and its greater response to treatment suggest that the carpal age and the phalangeal-metacarpal age should be considered independently during evaluation of skeletal maturation.
