Wrist (Distal Radius) ORIF

Download this patient information sheet (PDF)

What’s the Problem?

Your wrist joint is commonly injured either by falling or in a traumatic accident. In some cases, a plaster is sufficient for treatment, but in others (depending on your overall health and activity, as well as the pattern in which your wrist/distal radius has broken), then surgery is recommended.

How can you treat it?

In some instances, non-surgical treatment is appropriate. This includes:

• Taking pain relief
• A plaster around the wrist – usually for 6 weeks
• Physio or Hand Therapy to mobilise the wrist and surrounding muscles/tendons after the plaster has been removed

Ultimately, surgery is only reserved for patients whose injury is severe enough that they would have symptoms of severe wrist pain, stiffness and immobility without it.

The Operation

A wrist ORIF involves an incision down the front of the wrist. The broken bone fragments are placed back into their correct position, and then permanently held there with plates and screws. X-rays are taken intra-operatively to confirm positioning.

The Anaesthetic

You will be asleep for the duration of the operation (ie a general anaesthetic). The anaesthetist may talk to you about a nerve block before the operation, which helps with pain relief and generally lasts 24-48 hours. Alternatively, Mr Lau can put local anaesthetic into the wound whilst you are asleep, which can also help reduce pain.

What are the Risks of this Operation?

• Infection:
  Usually only a superficial wound infection to the top-most layer of the skin. In rarer cases a deep infection can develop and this is a serious complication that may require further surgery and exchange of the implants. Rare but serious, <1%.
• Stiffness and ongoing pain:
  It is common to have stiffness for a few months after the operation. This is because your wrist needs to be splinted to allow the bone to heal. Physio or Hand Therapy after surgery will help with improving movement, but some wrist rehabilitation will be required. Occasionally, the stiffness may be secondary to metal plate, and a second operation may be required to remove it.
• Damage to the nerves and blood vessels around the wrist.
  Rare but serious, <1%
• Complex Regional Pain Syndrome (CRPS):
  This is a chronic pain response that develops after an insult (like trauma or surgery) which we don’t have a full understanding of. It usually presents as ongoing burning or stinging to the hand, with change in sensation as well. Some factors increase the risk of developing this such as injury to the hands or feet, middle age and female gender. Mr Lau routinely prescribes Vitamin C post operatively, which has been shown in some studies to reduce the development of CRPS, but if it does develop, then a prolonged rehabilitation with hand therapy may be required.
• Tendon irritation:
  A number of tendons to the fingers pass across the wrist joint. Sometimes, these tendons (particularly to the thumb) can be irritated by the plates or screws that are placed on the bone. If that occurs, then the metalware can be removed as a secondary operation after the fracture has healed. Very rarely does the tendon itself rupture (<1%) and in fact is more common after non-surgical management/plastering of a wrist fracture
• Metalware Removal:
  Ideally, the metal plates and screws stay inside your wrist for life. In some cases, however, the metalware may become irritable to you with movement, or to the tendons of the fingers. If this occurs, the plates and screws can be removed once the fracture has healed – usually at least 6 to 12 months after the first operation. This is a day procedure and no rehabilitation is required.

Benefits

If Mr Lau recommends surgical fixation of your wrist fracture, it is because he feels you will have a better outcome with surgery. In particular, your wrist will be more pain free, have a greater range of motion and have greater functional improvements than if it was treated non surgically.

What can I expect?

You will wake up with your arm in a sling after your surgery and in a half-plaster. If you have had a nerve block, you shouldn’t feel any pain till the next day. The nurses will provide you pain relief and the next morning a physio or hand therapist will see you to go through some exercises you can do to mobilise the fingers and elbow to prevent excessive stiffness in these joints. These exercises will change over the next few weeks to months but you should try to do them regularly to maximise your rehabilitation.

Most patients spend 1 day in hospital after surgery, before going home. A number of allied health staff (physios, occupational therapists) will make sure you have adequate support at home before discharge. An appointment will be made for you for a wound check at 2 weeks. At this time, the plaster will be removed and a plastic removable splint made for you by a hand therapist. This splint is removable and allows for washing, whilst also keeping your wrist immobilised. Another appointment with Mr Lau will be at 6 weeks with repeat XRs

What should I avoid doing?

• In the first 2 weeks: keep your plaster/wound dry. Try to mobilise your fingers and elbow as much as possible
• Between 2 and 6 weeks: you will be placed into a moulded thermoplastic splint which allows for washing of the hand/wrist. Gentle flexion and extension of the wrist is possible, as well as continued elbow/finger exercises. You can pick up lighter objects such as a phone or cup with the affected side. You will have physio or hand therapy to help you with rehabilitation
• Between 6 and 12 weeks: full mobilisation of the wrist, fingers and elbow. The only restriction is no heavy lifting (weights, heavy pots/pans etc) till after 12 weeks.

Return to…?

• Work: Depends what you do. Desk based work can be done from 2 weeks post operatively, if you can do these tasks single handedly. Otherwise generally 6 weeks before you can use both hands freely whilst seated.
  For manual work, it depends on what kind of lifting/pushing you do, but generally not before 3 months
• Drive: In Australia, you can’t drive unless you are in full control of both your arms. Therefore, whilst you’re in a sling, you cannot drive. Generally 6 weeks post operatively.
• Sports/Hobbies:
• Gentle swimming: after 6 weeks
• Gardening (light tasks only): 8-12 weeks
• Bowls: after 3 months
• Golf, tennis, badminton, squash: after 4-6 months
• Weights: commence after 3 months
