The anatomic-and-functional condition of the upper limb in patients with achondroplasia in the long-term periods after humeral lengthening

The data of the results of studying the anatomic-and-functional condition of the upper limb in the long-term period after humeral lengthening are demonstrated in the work. The results of the study performed allow to draw a conclusion that the technique of bifocal distraction osteosynthesis used for lengthening of humeral segment gives the possibility to achieve the lengthening amount planned, to increase the functional potentials of the upper limb and in addition to preserve the motor skills attained before. The results of lengthening have been analyzed in a group consisting of 30 patients at the age of 9-15 years. The patients have been assessed for the results of lengthening using additional methods of study both in the process of lengthening and in the periods of 1 -5 years after osteosynthesis completion.
