How practise the feet and ankles work?

Our feet are made up of 26 basic and more than 33 joints arranged in columns and arches that vary in stiffness and flexibility. Many common bug can occur in this complex structure.

The foot is usually separated into three different parts:

The dorsum of your foot (hindfoot) is fabricated upwards of your heel os (calcaneus) and your ankle (talus). They're joined together by your subtalar articulation, which allows your human foot to move from side to side.

Your ankle bone is joined to your leg bones (tibia and fibula) at your ankle joint, which acts like a hinge. This allows your human foot to bend up and down.

The middle of your human foot (midfoot) is made upwardly of five tarsal basic. These form the curvation of your human foot. Your tarsal bones are connected to the forepart and dorsum of your foot by muscles and the arch ligament (the plantar fascia). They act as shock absorbers when we're walking or running.

The front of your foot (forefoot) is made upwardly of your toe basic (phalanges), which are connected to 5 long bones (metatarsals) by joints. The joints in your toes don't move very much. Your forefoot takes half of your body's weight.

The muscles in your lower leg are fastened to basic in your feet past tendons, and they command movement that allows us to stand, walk, go along tiptoes and jump. These muscles motion your toes and control the position of your foot as it hits the ground, allowing it to go flexible and cushioning the bear upon. They also make the arches of your anxiety more than rigid to push button your trunk frontwards when you motion.

Your heel bone is connected to the calf muscles in your lower leg by your Achilles tendon, which is the most important tendon for movement. The tibialis posterior tendon, which attaches the underside of your foot to your lower leg, helps supports the arch of your human foot and allows y'all to plough it inwards.

The main nerve of your foot controls the muscles in your sole and gives feeling here and to your toes. Other nerves give feeling to the tiptop and outside edge of your human foot.

Practise I need surgery?

Most people with problems in their feet or ankles won't demand surgery. The decision whether to operate depends on a number of factors:

  • how bad your symptoms are (pain and the effect this has on your life)
  • your needs
  • your response to other treatments, including drugs, orthoses and special footwear.

Talk over these with your healthcare professionals, who'll exist able to advise you on whether they think surgery would be a suitable choice.

The decision to accept foot and talocrural joint surgery is usually based on lifestyle choices and the data given by surgeons rather than beingness essential in terms of life and death. Simply if your skin is afflicted or your anxiety are rapidly becoming deformed, information technology'due south important to go an assessment for urgent surgery to avoid infection and alarm your healthcare professionals to possible stress fractures. You lot'll ever have the final decision on whether to accept the operation.

You may feel nervous, stressed or scared if you've been told yous need surgery. Finding out as much as you lot can most the operation and understanding the process volition help you lot feel calmer and more in control.

Common types

Weather that may need surgery include bunions and hammer toes, ankle arthritis, Achilles tendon disorders and plantar fasciitis.

Bunions

Bunions are bony lumps that develop on the side of your foot and at the base of your big toe. They're the result of a condition chosen hallux valgus, which causes your big toe articulation to curve towards the other toes and become plain-featured. If symptoms carry on over a long menstruation, your toe may need to exist surgically corrected. This involves straightening your big toe and metatarsals, a process chosen an osteotomy. Although this may make your joint stiffer, information technology works to ease the pain.

Nigh surgery tin be performed every bit a day case and takes up to an hour. Your pes will be bandaged and you'll need to wear a Velcro surgical shoe for four to six weeks later on.

If your bunion has been caused by rheumatoid arthritis, you may as well develop rheumatoid nodules. These business firm, pea-sized lumps can occur at force per unit area points such every bit your big toe joints, the back of your heels or on your toes, merely they tin can exist surgically removed.

Sometimes swellings or bursae on the joints in your feet are also called bunions, but these aren't the same equally bunions caused by hallux valgus and don't demand surgery.

Hallux valgus is different to hallux rigidus, which is osteoarthritis of the large toe articulation. Hallux rigidus causes stiffness in your big toe and you won't be able to move information technology every bit far. If treated early on, surgery can be used to remove painful osteophytes (overgrowth of new os) that can develop and allow more joint motility to return. In more than advanced cases, fusion surgery (joining basic together to make one stiff bone where there two) gives splendid pain relief, although it volition mean that the joint volition no longer bend when you walk so you won't be able to wear loftier-heeled shoes.

Advantages

The primary advantages of foot and ankle surgery are:

  • long-lasting pain relief
  • better function and mobility
  • a greater pick of comfortable footwear improved advent of your feet, depending on the procedure.

Disadvantages

As with any surgery, results tin vary from person to person and there can occasionally exist complications.

There are some possible disadvantages to pes and talocrural joint surgery:

  • Replacement joints aren't every bit hard-wearing or long-lasting equally natural joints.
  • Some operations restrict joint movement (although this doesn't mean that information technology'll reduce your mobility).
  • You lot may non be able to utilize your foot properly for some time later on the operation (for instance, you may need to keep weight off your foot for iii months after an ankle fusion). This can exist a item problem if you're likely to have problems getting around using crutches.
  • Occasionally small nerves effectually the cut in your skin (the incision) can be damaged, leading to patches of numbness.
  • There can be complications during surgery, for example swelling, stiffness or infection.
  • In some cases where bones are joined (fused) together, the bones can take longer to fuse together than expected and y'all won't be able to utilise your foot properly during this time. Occasionally a non-union occurs – where the fusion doesn't work properly – and you may need further surgery.

Complications

Complications of foot and ankle surgery tin include infections, swelling and stiffness, and wound haematoma (haemorrhage).

If you're generally healthy the risk of a serious complexity from an operation is very pocket-sized. Every possible care is taken to prevent complications, only in a few cases these practise happen. For case, some people can develop an infection, so it's important to speak to your doctor direct away for antibody treatment if yous notice whatsoever signs, including:

A wound haematoma is when blood collects in a wound. It's normal to have a small amount of claret leak from the wound subsequently any surgery, and normally this stops within a couple of days. But occasionally blood may collect under your skin, causing a swelling. This can cause a larger merely temporary leakage from the wound usually a week or so subsequently surgery, or it may crave a smaller second operation to remove the claret collection. Drugs like aspirin and antibiotics tin can increase the risk of haematoma later surgery.

Research and new developments

We're supporting the Outcomes in Talocrural joint Replacement Study (OARS) at the Academy of East Anglia. The written report will provide prove of how the outcome of total talocrural joint replacement is influenced by:

  • the characteristics of the patients undergoing surgery
  • the nature of their ankle disease
  • the type of implant
  • the way in which the patient is managed before and after surgery

This study volition also examine the relative costs and benefits of surgery. To collect this data, the researchers volition employ a newly developed questionnaire chosen patient-reported outcome measure, or PROM, on 600 people who have undergone talocrural joint replacement surgery. This study will allow a greater understanding of who might do good nigh from full ankle replacement for severe ankle affliction.
