Lengthening over Nail (LON)

Lengthening over Nail (LON) is a surgical technique used to gradually stretch and grow new bone in cases of limb or bone deformities. It involves implanting a device along the bone and inserting a stainless steel or titanium nail inside the bone canal. After surgery, the external device gradually pulls the nail and bone apart at a controlled rate, encouraging new bone to form in the gap. This process allows for precise lengthening or correction of deformities while preserving soft tissues and joint function. LON is effective for limb lengthening and deformity correction, offering stability and improved healing outcomes.
