Humeral Lengthening with a Motorized Intramedullary Lengthening Nail

The patient is a 19 year old male with a 5 cm unilateral humeral shortening. The patient had back and neck pain and was cosmetically dissatisfied. The humerus was lengthened 4 cm with a motorized intramedullary lengthening nail (FITBONE®, WITTENSTEIN Intens GmbH, Igersheim, Germany) which is primarily used for lower limb lengthening. At the latest follow-up 1 month after nail removal, the patient did not have back or neck pain or cosmetic complaints. The patient was very satisfied with the result. However, shoulder abduction was reduced from a preoperative range of 100° to a postoperative range of 80°.
