title: A technique of percutaneous multidrilling osteotomy for limb lengthening and deformity correction.
abstract: We have recently developed a technique of per-cutaneous multidrilling osteotomy for limb lengthening and deformity correction. The bone is drilled percutaneously, using a special drill guide, and osteotomy is accomplished by connecting the multiple drill holes with a small chisel. The bone segments are subjected to slow progressive distraction with an external fixation device. We have lengthened 33 limbs in 22 patients with congenital or post-traumatic limb shortening and/or bone deformities. All the patients underwent the proposed lengthening and/or correction of the bone deformities through a single-treatment procedure. None of the lengthened segments resulted in nonunion. This technique can prevent undesirable bone cracks and preserve soft tissue around the osteotomy site, and is also applicable to other fields of orthopedic surgery.
