The most common way to fix a shorter leg is through limb lengthening surgery.
Limb lengthening surgery aims to equalize leg lengths and can improve function, reduce pain, and enhance appearance. Here's a more detailed breakdown of this process:
Limb Lengthening Surgery
This surgical procedure focuses on gradually lengthening the shorter leg. Two main types of devices are used:
-
External Fixators (e.g., Hexapod Frame): These devices are placed on the outside of the leg. They consist of rings connected by rods, allowing precise and controlled lengthening.
- The surgeon makes a cut in the bone (corticotomy).
- The external fixator is attached to the bone with pins or wires.
- Over time, the rods are adjusted, gradually pulling the bone segments apart.
- New bone grows in the gap, lengthening the leg.
- The fixator remains in place for several months until the bone has healed sufficiently.
-
Internal Lengthening Devices (e.g., PRECICE nail): These are implanted inside the bone.
- The surgeon inserts a telescopic rod into the bone marrow canal.
- A small incision is made to the device, allowing it to be lengthened with an external remote control or magnetic device after surgery.
- Similar to external fixators, the bone is cut (corticotomy) and the device is used to gradually lengthen the bone.
- New bone fills the gap.
Considerations
- Consultation with a specialist: A thorough evaluation by an orthopedic surgeon specializing in limb lengthening is crucial. This evaluation includes physical examination, X-rays, and other imaging studies to determine the cause and extent of the leg length discrepancy.
- Age and health: The patient's age and overall health influence the suitability of limb lengthening surgery.
- Recovery: The recovery process can be lengthy, involving physical therapy and rehabilitation to regain strength and mobility.
- Risks and complications: As with any surgery, limb lengthening carries potential risks, including infection, nerve damage, blood clots, and delayed bone healing.
While limb lengthening is the most common solution for significant leg length discrepancies, physical therapy, shoe lifts, or orthotics can address minor differences effectively.
