Limb Lengthening & Deformity Repair
Limb lengthening surgery is an inpatient procedure to lengthen the bones in the arms or legs. This is a gradual process that takes advantage of the body's ability to generate new bones.
The whole process may take several months to make sure that the bones slowly increase in length. Likewise, the soft tissues, blood vessels, nerves, and ligaments surrounding the bone should stretch slowly over time and support the lengthened bone.
Limb Lengthening and Deformity Repair is a very sophisticated orthopaedics sub-specialty that Dr. William Terrell offers at Pinnacle. He is one of the few limb lengthening and deformity correction specialists in the United States.
Who is eligible to undergo limb lengthening and deformity repair?
Patients are encouraged to have limb lengthening and deformity repair if they have bones with:
- a considerable difference in limb length
- severe fractures
- non-unions
- mal-unions
- failed fixations
These conditions can be a result of either trauma or a defect and vary in severity. This orthopaedic specialty also involves a broad range of treatments of bones that won't heal, have formed or healed incorrectly, or have become infected. This includes cases with patients who have had multiple procedures, such as bone grafts, that have not healed properly.
What are the potential risks involved?
Limb lengthening has very minimal scarring and a 95% success rate. This procedure is safe and has very promising potential. However, just like any surgery, it has a number of risks such as:
- Nerve damage
- Damage to surrounding tissues
- Osteomyelitis or bone infection
- Poor bone healing
- Restricted bone growth
If you want to have limb lengthening surgery, talk to Dr. William Terrel, our expert orthopaedic surgeon. Based on your medical history, he will discuss the treatment plan, benefits, and possible surgical risks to find out if limb lengthening is a good option for you.
What to expect during the recovery process?
After undergoing limb lengthening in Woodstock or Marietta, you will go through two phases of recovery.
Distraction phase
In this phase, the orthopaedic surgeon will gradually pull apart the two bone segments. This promotes the growth of new bones (called regenerate bones) at the site where they were cut.
To ensure continuous bone growth, the gap between the two bone segments will be increased 4 times a day. Each adjustment will increase the gap by 0.25 millimeters so that each day, the bone will be distracted for a total of 1 millimeter. This may slightly differ, depending on the target bone. The body will continue to produce new bone tissue to fill the growing space between the bone segments until the desired bone length is achieved.
The patient may need to visit his orthopaedic doctor for follow-ups to make sure that the bone is lengthening at a safe and recommended pace. This can be determined based on how the new bone appears on an X-ray. Depending on the assessment, the doctor may increase or decrease the rate of distraction.
Consolidation phase
In the consolidation phase, the new bone slowly hardens and solidifies. A target length of 5 centimeters requires about 2 months of distraction and 3 more months of bone hardening. Therefore, the lengthening device will need to stay in place for 5 months. It will not be removed until the new bone has fully healed, hardened, and calcified.
During this phase, patients who underwent leg lengthening would still need to use crutches or a walker. They will now be advised to start putting weight on the arm or leg to stimulate bone healing and hardening.
Once the new bone has fully healed, the surgeon will now remove the orthopaedic lengthening device.
After removing an external fixator, the patient will still need to wear a cast or a brace for a month to add protection and stability to the new bone. On the other hand, if an internal device was used and removed, there's no need to apply a cast.
You will also be advised to undergo physical therapy to improve range of motion, limb strength, and limb mobility as the bone heals.
What is deformity repair?
Deformity repair is performed on bones that are out of alignment, bent, or twisted. The goal of surgery is to straighten the limb to achieve normal function.
There are two ways to repair a deformity. Your orthopedic surgeon will decide which of these two approaches is best for your condition.
Acute correction
In an acute repair or correction, all the necessary procedures are done in a single surgery. The first step is called osteotomy, wherein the target bone will be cut into two separate segments. Next, the orthopedic surgeon will correct the position of the bone.
The third step includes the insertion of an internal device, such as an internal rod or a metal plate, to keep the bone in its proper position while it heals. Once the bone is completely healed, the internal device will be removed.
Gradual correction
In a gradual repair, the corrections are performed over several weeks or months. Before osteotomy, the surgeon will first apply an external fixator to the bone to keep it in its position.
Distraction Phase. After the surgery, the doctor will instruct the patient on how to adjust the external fixators to separate and align the bone segments. New bones will form in the space between them.
Just like in limb lengthening, the patient also needs to attend physical therapy sessions and avoid putting weight on the limb.
Consolidation Phase. This stage is longer than the distraction phase, wherein the new bone gradually hardens and solidifies. The external fixator remains attached to the bone to keep it in position.
During the healing phase, patients are encouraged to increase their intake of protein, vitamins, and minerals and avoid any form of nicotine. With the help of a physical therapist, they may now start to put some weight on the limb to facilitate bone healing. The external fixator will be removed once the bone has fully healed and solidified.
Answers to common questions about limb lengthening surgery:
Is the procedure painful?
You will be under anesthesia during the surgery, so you will not feel any pain. During the lengthening process, you may experience some soreness in the operated limb. Your doctor can give you pain relievers to reduce the pain and discomfort.
How much can the bone be lengthened?
Typically, the bone can be lengthened by 2 inches per treatment. However, this largely depends on your specific circumstances. Your orthopaedic surgeon will determine the amount of lengthening that can be safely done to your limb.
Can I use my limb during treatment?
During the distraction phase, you can use assistive devices like a walker or crutches to move around, but you are not allowed to bear weight on the operated leg.
During the consolidation phase, you will now be encouraged to gradually put weight on the operated leg. Depending on your pain tolerance and leg strength, you may slowly begin to walk without the help of mobility aids.
How long will the lengthening take?
The amount of time largely depends on how much the limb needs to grow. Lengthening usually takes 1 mm per day.
It is crucial to adhere to recommended adjustments because:
- If the lengthening is too slow, the new bone may harden prematurely even before the treatment is complete.
- If the lengthening is too fast, there might not be enough time for new bones to form.
Generally, patients take 6-9 months from the time of surgery to full recovery. This timeframe may vary, depending on your overall health condition and adherence to treatment.
When can I return to normal activities?
You can return to your normal activities as soon as the bone has healed completely and your range of motion and muscle strength have returned to normal with the help of physical therapy.
How can I ensure that the lengthened limb will function well?
It is important to follow the doctor's advice. Physical therapy and exercise are also essential to ensure that the bones, soft tissues, nerves, muscles, and ligaments have maintained their function.
Teamwork is a crucial determinant to a successful limb lengthening surgery and deformity repair. This includes the skills and experience of the orthopaedic surgeon, the expertise of the physical therapist, the moral support of loved ones, and the commitment of the patient to the treatment regimen.
What foods should I avoid?
While the new bone is healing, patients should not take nicotine in any form. Nicotine can interfere with healing, as it slows the production of bone-forming cells and affects the body's ability to absorb calcium.
Patients should also eat a healthy and protein-rich diet. Protein has a positive effect on bone mineral density and can help produce stronger bones. Your doctor may also prescribe you with vitamins and mineral supplements.
