Limb Lengthening Surgery Side Effects

Short Stature? Do You Wish You Were Taller? Limb lengthening surgery aims to lengthen a bone in the arms or legs, usually to improve stature or address limb length disparities.  

After the bone is surgically sliced, the pieces are progressively separated as new bone forms to replace the space. However, adults and children can both have this surgery.

What is Limb Lengthening Surgery?

Limb lengthening surgery is a specialized medical procedure that is designed to increase the length of the bones, especially in the arms and legs. However, there are various reasons to perform this surgery, which range from aesthetic aspirations to correcting limb discrepancies and treating conditions that cause shorter bones, such as dysplasia or congenital deformities. 

Common Limb Lengthening Surgery Side Effects

Limb lengthening surgery has several potential risks, including:

• Slow or rapid bone healing

The daily rate of bone lengthening in limb lengthening is usually 1 mm.  Rarely, during this process, bone repair could go too fast or too slow. Using X-rays to track progress, your surgeon modifies the course of treatment as necessary.

• Muscle and joint complications

Muscles have to adjust to the longer bones as limbs lengthen. Leg mobility may be impacted if muscle adaptation does not keep up, which may result in problems including joint stiffness and muscle contractures.

• Osteomyelitis (bone infection)

An uncommon side effect of limb lengthening surgery is osteomyelitis, or bone infection, particularly when external fixation is used. It occurs when germs infiltrate the surgical site, leading to infection and inflammation.

• Nerve and blood vessel injury

There is a slight chance that limb lengthening operations, particularly those that include external fixation, could cause damage to blood vessels and nerves. Pin and wire insertion can cause these injuries by compressing or damaging adjacent tissue.

• Pin loosening 

Pins may come loose during external fixation limb lengthening treatments for technical reasons. Poor anchoring, frame stiffness, and improper insertion are some of these problems. 

• Pin site infection

The use of external fixation techniques may result in pin site infections. These infections arise from the entry of microorganisms into the surgical site, frequently as a result of inadequate cleanliness or dressing changes. 

• Postoperative swelling

Due to fluid accumulation at the surgical site, swelling during limb lengthening surgery is a typical aspect of the healing process.  However, pain, discomfort, and trouble moving can result from it, which could postpone healing.

• Pain and sleeping difficulties

Following significant orthopedic surgery, pain is a typical condition. The pain is usually at its worst in the days after the treatment and can range from little discomfort to severe pain.  However, when pain is properly managed and cared for, it normally goes away over time.  

• Psychological impact

Having limb lengthening surgery may have an impact on your mental and physical health. Although there may be major changes as a result of the treatment, there may also be emotional issues that require attention.

Limb Lengthening Surgery Recovery Time

Every patient recovers from the limb lengthening treatment differently, and the consolidation phase might occasionally take a long time, particularly for adults. Children often recover half as quickly as adult patients.  For instance, if a young patient wants to increase their height by 1.5 inches, they will wear the fixation device for three months.

However, physical therapy is essential to maintain the muscular strength and flexibility of joint flexibility during the healing process. Patients are encouraged to take calcium supplements and consume a healthy diet.  Gradual weight-bearing is advised to speed up bone mending, and the patient takes calcium and vitamin D3 supplements.

Long-Term Effects of Limb Lengthening Surgery

• Joint Issues : As bones grow longer, they may exert strain on nearby joints, which may result in stiffness, arthritis, and a reduction in range of motion. 
• Nerve Damage : During surgery, there is a chance that nerves will be damaged, which could result in weakness, numbness, or persistent discomfort. 
• Malalignment : Long-term problems with bones can include malalignment of the lengthened bone, poor consolidation (hardening), or bone that does not reach the appropriate length. 
• Osteomyelitis : Persistent infections at the surgical site or surrounding pins are a possibility if external fixators are used, even though they are frequently treated during recovery.
• Scarring : Pin sites and surgical incisions may leave visible, possibly permanent scars. 
• Psychological Impact : When results don't live up to expectations, patients may experience a range of emotions, including disappointment, low self-esteem, and issues with body image. 
• Limited Long-Term Data : Because of the process's recent infancy, long-term data is still being collected, and the full extent of long-term effects is currently being examined.

What happens if leg lengthening fails?

A number of issues that may arise from leg lengthening surgery may necessitate additional care. These can include infections, soft tissue disorders (contractures, nerve entrapment), problems with bone development (malunion or nonunion), and hardware failure.  The specific problem is addressed by treatment modalities that include physical therapy, bone grafting, hardware exchange, and, in certain situations, additional surgery.
