Problems with substantial limb lengthening.

Limb lengthening takes careful planning and meticulous outpatient care and still is burdened by minor complications. Experience may lessen major complications, but pin tract problems, swelling, and pain will plague these patients. A large group of patients can benefit from lengthening procedures, and new techniques are improving the risk-benefit balance. A thoughtful approach is needed by the surgeon, especially taking time to fully inform the patient about the time, effort, and problems involved in substantial limb lengthening.
