How Transverse Tibial Bone Transport Supports Complex Wound Care

Restoring Failing Wounds with Limb Reconstruction Expertise

Complex lower leg wounds are often far more than a problem on the surface. They can follow major injuries, repeated surgery, infection, diabetes-related problems, or poor blood supply. Sometimes they refuse to heal despite good standard care. When skin breaks down over the shin or ankle, the bone and soft tissues underneath can become exposed or infected, putting the whole leg at risk.

Poor circulation, infected or dead bone, and loss of muscle or skin can all slow healing. In some cases, this leads to serious talks about amputation, because it seems that all reasonable options have already been tried. This is understandably frightening for patients and families, and many people want to know whether there is anything else that might save the leg.

At Sussex Limb Reconstruction, based in Sussex and led by orthopaedic surgeon Mr Alastair Robertson and Mr Enis Guryel, we focus on limb preservation and complex reconstruction. Our aim is to deal with the deeper structural problems that stop wounds from healing, not just the surface appearance. One of the techniques we use is called transverse tibial bone transport. In simple terms, this is a way of slowly moving a small piece of shin bone to help improve blood flow in the leg and give long‑standing wounds a better chance to heal.

Understanding Transverse Tibial Bone Transport in Simple Terms

The tibia is the main weight-bearing bone in the lower leg, running from the knee to the ankle. In transverse tibial bone transport, we make a carefully planned cut across a small section of this bone in the upper or middle part of the shin. This small piece of bone stays attached to its blood supply and surrounding soft tissues but is freed enough to move slowly sideways within a controlled frame.

After surgery, the bone is given a short period to rest. We then start the "transport" phase. The small bone segment is moved a tiny distance each day, guided by an external frame around the leg. This slow, steady movement aims to:

• Allow the surrounding soft tissues to adapt gradually  

• Stimulate new blood vessel growth to the lower leg and foot  

As blood flow improves, tissues that were previously starved of oxygen and nutrients can begin to recover. This is why this technique can help some chronic wounds that have not healed with more conventional methods.

The process is usually guided by specialist circular external frames that attach to the bone through thin wires or pins and allow very precise adjustments in multiple directions. In some situations, bone transport can also be combined with an internal device that sits inside the bone and works alongside the external frame to provide stability and controlled movement.

Throughout treatment, the transport is carefully planned, measured and monitored. We adjust how fast and how often the bone segment is moved according to X-ray findings, wound progress and how the leg feels, with the aim of supporting both bone health and wound healing in a safe, controlled way.

How Bone Transport Supports Complex Wound Management

Some wounds simply do not respond to dressings, vacuum (negative pressure) therapy or even plastic surgery techniques like skin grafts and flaps. This is particularly true when there is:

• Ongoing or previous bone infection  

• Poor circulation to the lower leg and foot  

• Unstable or badly aligned bone underneath the wound  

• Significant loss of soft tissue (muscle, fat or skin) around the shin or ankle  

In these circumstances, simply changing the dressing or adding another skin graft may not be enough, because the underlying biology is not right. If bone is unhealthy or the blood supply is too poor, the wound edges cannot knit together and the area remains fragile and prone to breaking down again.

Transverse tibial bone transport aims to improve this environment. By encouraging new blood vessels to grow, it can boost circulation to the lower leg, ankle and the foot. For some patients, this increased blood flow helps stubborn ulcers, post-injury wounds and non-healing surgical wounds to look healthier and move towards closure.

The real benefit often comes when bone transport is part of a broader limb-preservation plan, which may include:

• Careful stabilisation and realignment of fractures  

• Surgical cleaning and treatment of bone infection  

• Working with plastic and vascular surgeons to improve soft tissue cover and blood flow  

• Attention to diabetes control and overall health, including smoking cessation, nutrition and exercise where possible  

What Patients Can Expect From Treatment and Recovery

If you are referred to Sussex Limb Reconstruction with a complex wound or a fracture that is not healing, the first stage is always a detailed assessment. This usually involves:

• A full discussion of your history, symptoms and goals  

• Examination of the limb, including the wound and overall alignment  

• X-rays, and often MRI or CT scans if they are likely to help  

• Blood tests to look for infection or other issues  

We then talk through all possible options, from non-operative care and smaller procedures to more extensive reconstruction or, when there is no safer alternative, amputation. Transverse tibial bone transport is only considered when it is likely to improve the health of the limb and support wound healing.

Surgery usually involves a stay in hospital. During the operation, we perform the planned bone cut in the tibia, apply a circular frame or other fixation system, and address any obvious infection or deformity at the same time. After a short rest period while the bone begins to heal, the transport phase starts, with small daily adjustments to the frame or, where used, gradual activation of any internal bone transport system.

At home, patients are typically asked to:

• Turn the frame adjusters several times a day, following clear written and verbal instructions  

• Attend regular clinic visits for X-rays and wound checks  

• Work with physiotherapists to keep nearby joints moving and muscles strong  

• Look after pin sites and frame components carefully to reduce infection risk  

It is common to feel tightness or aching as the bone segment moves and tissues stretch. Pain relief, support from our nursing and physiotherapy teams, and careful adjustment of the movement rate all help keep this manageable. Throughout this time, we monitor both the wound and the bone to check that progress is steady.

Safety, Risks, and Who This Treatment Is For

Transverse tibial bone transport is a major treatment, so it is important to be realistic about risks and responsibilities. Commonly discussed risks include:

• Infection around the pins or wires of the frame  

• Joint stiffness if physiotherapy is not maintained  

• Discomfort or pain related to bone movement or the frame  

• Delayed or incomplete bone healing  

• The need for further procedures if problems arise  

Modern circular frame systems are designed to give stable fixation and precise control, which can help reduce some risks. Careful planning, patient education and regular follow-up visits allow us to spot and address any issues early, whether that is a pin-site infection, stiffness or a concern with bone formation.

This approach is generally reserved for patients with serious limb problems in whom standard care has not worked or is unlikely to succeed. People who may benefit include those with:

• Chronic lower leg or ankle wounds that have failed to heal  

• Infected fractures of the tibia that have not joined properly  

• Diabetes-related foot or leg problems where blood flow and bone health are major concerns  

• Threatened limbs where amputation has been raised as a possible outcome  

Every case is assessed individually. Techniques such as external frames, transverse bone transport and, where appropriate, internal bone support devices are offered only if the potential benefit to limb survival and function clearly outweighs the risks. Shared decision-making is central, so patients and families understand the likely commitment, timeframes and possible outcomes before proceeding.

Taking the Next Step Toward Limb Preservation

For patients and families facing a non-healing leg wound or a fracture that will not unite, it can be hard to know when to ask for a specialist opinion. When amputation has been mentioned, or when repeated dressings and operations have made little difference, it is reasonable to explore whether advanced limb reconstruction might provide another way forward.

At Sussex Limb Reconstruction, our work combines fracture care, limb realignment, external fixation and techniques such as transverse tibial bone transport to support wound healing and limb preservation. While treatment can be lengthy and demanding, it can offer a real chance of keeping a limb that might otherwise be lost, and of improving function in very challenging situations. We work closely with patients and families at every stage to explain the process, answer questions and support you through treatment and recovery.
