Orthoplastics explained: how bone and soft tissue specialists work together after severe leg injuries
If you’ve had a serious leg injury, especially after an accident, you may be left with more questions than answers. Why has recovery taken so long? Why does pain persist even though the bone has healed? Why are so many specialists involved?
This article is based on the insights of Professor Nima Heidari, consultant orthopaedic surgeon, and Mr Georgios Pafitanis, consultant plastic and reconstructive surgeon, who work together managing complex lower limb trauma. They explain orthoplastics in practical terms and why joined-up care matters so much after severe injuries.
What is orthoplastics?
Orthoplastics is a collaborative approach to treating complex injuries, most often in the lower limb. It brings together orthopaedic surgeons, who focus on bones and joints, and plastic surgeons, who specialise in soft tissues such as skin, muscle, blood vessels and nerves.
After some injuries, it may not be enough to fix the bone alone. Damage often extends to everything around it, including the tissues that protect the bone, supply blood and allow movement and sensation.
Orthoplastics exist to bring those perspectives together so decisions are made with the whole limb – and the whole person – in mind.
‘I see things very much from the bone-centred point of view. You see things from the soft tissue reconstruction point of view. And actually, the answer is somewhere in between.’
– Professor Nima Heidari
Why severe leg injuries are more complex than a broken bone
In ‘high-energy’ trauma, such as road traffic collisions or falls from height, the force that breaks the bone also passes through the surrounding tissues. Skin, fat, muscle, blood vessels and nerves can all be affected.
This surrounding layer is often referred to as the ‘soft tissue envelope’. Even when the bone heals well, damage to this envelope can affect recovery long after the fracture has united.
That is why patients may continue to struggle with pain, swelling or poor function despite X-rays that appear reassuring.
‘When someone has an open fracture, the energy didn’t just go through the bone. It went through the soft tissues too.’
– Mr Pafitanis
The importance of early and collaborative decision-making
The first operation after a serious injury is critical. Surgeons must remove tissue that will not survive while preserving as much healthy tissue as possible.
There is no clear boundary between damaged and viable tissue. Decisions rely on experience, judgement and close collaboration between specialists. Even with best practice, outcomes are not always predictable.
Despite careful early management, further surgery is common, with up to 30% of patients with complex lower limb trauma requiring additional procedures. This reflects the severity of the injury rather than shortcomings in care.
How orthoplastic teams assess complex lower limb injuries
Assessment is not a single event. It evolves over time and focuses on understanding both the injury and the person living with it.
Understanding the injury journey
For patients seen months or years after trauma, assessment typically starts by revisiting the original injury and the treatments that followed. Previous surgeries, healing timelines and any complications help build a clearer picture of what may still be affecting recovery.
Assessing blood supply and tissue health
Healthy tissues need a good blood supply. Orthoplastic surgeons often assess circulation carefully, sometimes using ultrasound to understand how effectively blood reaches the lower limb.
Seeing a blood vessel on a scan doesn’t always mean it’s working well enough. Functional blood flow matters for healing and symptom control.
Listening to the patient’s symptoms
Clinical assessment is guided by what the patient is experiencing. Pain, heaviness, numbness or reduced function often provide the most important clues.
Symptoms help determine whether the focus should be on wounds, circulation, nerves or a combination of factors.
Why pain can persist long after the bone has healed
One of the most confusing experiences for patients is ongoing pain after a fracture appears to have healed fully. But in many cases, this pain doesn’t come from the bone itself.
‘Up to 20% of people with tibial fractures will still have ill-defined pain two years later, even though the bone has healed.’
– Professor Heidari
The role of peripheral nerves in ongoing pain and disability
Nerves are part of the soft tissue envelope and are particularly vulnerable during high-energy trauma. Unlike skin or muscle, nerves can’t be replaced if they are damaged.
They are usually preserved, but this preservation can have consequences. Scar tissue can form around nerves as healing occurs. This may affect their blood supply and alter the signals they send to the brain.
Nerves act as the limb’s electrical wiring. When that wiring is disrupted, the brain may interpret abnormal signals as pain, even when everything appears healed during scans.
This helps explain why pain can persist despite good bone healing and stable reconstruction.
How nerve problems are investigated and diagnosed
Diagnosing nerve-related symptoms takes time and careful assessment. Surgeons often ask detailed questions about sensation, temperature changes and movement.
Examination may include testing touch, position sense and joint awareness. Specialist nerve studies can also measure how quickly electrical signals travel along nerves. These results help predict whether recovery is likely and over what timeframe.
Nerves regenerate slowly – often only millimetres per week. This means improvement can continue for months or even years after injury.
When further surgery may help – and when it may not
Surgery is considered when there is a clear structural problem that can be corrected, such as a nerve trapped by scar tissue or a painful neuroma (thickening of nerve tissue).
The aim is to reduce pain, improve function and lessen reliance on long-term medication.
However, pain often has more than one cause. Swelling, fluid not draining well (the lymphatic system), sensitive nerves and how you are feeling day to day can all play a part.
OS Clinic takes a cautious approach when it comes to surgery to ensure patient safety and long-term wellbeing are central.
‘If the benefit isn’t predictable, we don’t operate. We won’t expose someone to risk if we’re not confident it will help.’

Modern approaches to amputation: when is amputation needed?
In some cases, amputation may be required. If so, it is approached as a reconstructive procedure. The goal is to create a limb that can support a prosthesis (an artificial limb) comfortably and function well.
Modern techniques focus heavily on managing nerves to lower the chance of long‑term pain. If a cut nerve is left without a target, it may form a painful lump called a neuroma. It can also send mixed signals that the brain reads as pain from the missing part of the limb, known as phantom limb pain.
One technique is targeted muscle reinnervation. During this operation, the cut nerve is connected to a small branch of a nearby muscle. This gives the nerve a new job and can reduce the risk of neuroma pain and phantom limb pain for selected people.
‘Amputation is a reconstructive option. When it needs to be done, it needs to be done well and properly.’
– Professor Heidari
When to seek urgent specialist review
It’s important to trust your instincts if something doesn’t feel right. You should seek medical advice if you notice:
- Pain that is getting worse rather than slowly settling
- New weakness, numbness or changes in sensation in the leg or foot
- A wound that is slow to heal or starts to break down
- A sudden change in how well the limb moves or functions
Seek urgent medical attention if you notice:
- Redness or swelling alongside a fever
- Rapidly increasing pain, especially if the limb feels hot or unusually tight

FAQs
1. Is orthoplastics only used immediately after an injury?
No. While orthoplastics are essential in the early treatment of severe injuries, many patients are referred months or even years later. This is often because of ongoing pain, delayed healing or functional problems that persist after the initial treatment.
2. Why do some people need repeated assessments over time?
Complex injuries evolve. In the podcast, the surgeons explain that nerve recovery, scar formation and blood flow can all change gradually. Reassessment helps teams understand whether symptoms are improving naturally or whether further investigation is needed.
3. If scans look normal, why might symptoms still be taken seriously?
Imaging shows structure, not always function. Pain, altered sensation or weakness may relate to nerve behaviour or scarring, which doesn’t always show clearly on scans. This is why clinical examination and symptom history remain central to assessment.
4. How long can nerve recovery realistically take?
Nerves recover very slowly. In the discussion, nerve regeneration is described as occurring over millimetres per week. This means meaningful improvement can continue for months or even years after the original injury.
5. Will surgery always be offered if nerve pain is found?
No. The surgeons emphasise that surgery is only recommended when there is a clear problem that can be corrected with a reasonable expectation of benefit. If improvement is uncertain, non-surgical management may be safer.
6. Why do surgeons sometimes advise against further operations?
Further surgery carries risk. If pain is coming from several factors rather than one fixable issue, operating may not improve symptoms. The podcast highlights the importance of avoiding procedures that are unlikely to help.
7. What does a multidisciplinary team actually involve?
Orthoplastics often includes orthopaedic surgeons, plastic surgeons, pain specialists, physiotherapists and, where needed, psychological support. This reflects the fact that recovery affects both physical function and mental wellbeing.
8. Can function still improve years after the original injury?
Yes. The surgeons discuss how recovery doesn’t stop after one or two years. Nerve sensation and functional adaptation can continue well beyond this, which is why long-term follow-up and realistic expectations matter.
