Hallux valgus, often referred to as "a bunion," is a deformity of the big toe. The toe tilts over towards the smaller toes and a bony lump appears on the inside of the foot. (A bony lump on the top of the big toe joint is usually due to a different condition, called hallux rigidus.) Sometimes a soft fluid swelling develops over the bony lump. The bony lump is the end of the "knuckle-bone" of the big toe (the first metatarsal bone) which becomes exposed as the toe tilts out of place.
Bunions develop when the pressures of bearing and shifting your weight fall unevenly on the joints and tendons in your feet. This imbalance in pressure makes your big toe joint unstable, eventually molding the parts of the joint into a hard knob that juts out beyond the normal shape of your foot. Experts disagree on whether tight, high-heeled or too-narrow shoes cause bunions or whether footwear simply contributes to bunion development. Other causes include inherited foot type, foot injuries, deformities present at birth (congenital). Bunions may be associated with certain types of arthritis, particularly inflammatory types, such as rheumatoid arthritis. An occupation that puts extra stress on your feet or one that requires you to wear pointed shoes also can be a cause.
It is unusual to have much bunion or hallux valgus pain when out of shoe wear or at rest. There are exceptions to this and in particular if symptoms have been ignored during the day and the bunion has become very painful during the day then some symptoms may be present at night. The pain from the region of the great toe at rest or at night is however more often a symptom of an arthritic big toe (hallux rigidus) rather than a straightforward bunion. To confuse matters these two conditions can sometimes coexist. Bunion or hallux valgus pain is most often present when walking in enclosed shoes. There may be little bunion pain in sandals or barefoot. It is unusual to have much bunion pain when not putting weight on the foot or at night. If there is bunion pain at rest or at night then there may also be arthritic change within the toe.
When an x-ray of a bunion is taken, there is usually angulation between the first metatarsal bone and the bones of the big toe. There may also be angulation between the first and second metatarsal bones. These angular irregularities are the essence of most bunions. In general, surgery for bunions aims to correct such angular deformities.
Non Surgical Treatment
Somtimes observation of the bunion is all that?s needed. A periodic exam and x-ray can determine if your bunion deformity is advancing. Measures can then be taken to reduce the possibility of permanent damage to your joint. In many cases, however, some type of treatment is needed. Conservative treatments may help reduce the pain of a bunion. These options include changes in shoe-wear. Wearing the right kind of shoes is very important. Choose shoes with a large toe box and avoid narrow high heeled shoes which may aggravate the condition. Padding. Pads can be placed over the area to reduce shoe pressure. Medication. Nonsteroidal anti-inflammatory drugs may help reduce inflammation and reduce pain. Injection therapy. Injection of steroid medication may be used to treat inflammation that causes pain and swelling especially if a fluid filled sac has developed about the joint. Orthotic shoe inserts. By controlling the faulty mechanical forces the foot may be stabilized so that the bunion becomes asymptomatic.
Surgery is the only way to correct a bunion. A bunion will usually get worse over time, so if it's left untreated it's likely to get bigger and become more painful. If your bunion is causing a significant amount of pain and affecting your quality of life, your GP may refer you to be assessed for bunion surgery. The aim of surgery is to relieve pain and improve the alignment of your big toe. Surgery isn't usually carried out for cosmetic reasons alone. Even after surgery, there may still be limits to the styles of shoe you can wear. Bunion surgery is often carried out as a day procedure, which means you won't have to stay in hospital overnight. The procedure will either be carried out under a local anaesthetic or a general anaesthetic.
To help prevent bunions be sure your shoes don't cramp or irritate your toes. Choose shoes with a wide toe box - there should be space between the tip of your longest toe and the end of the shoe. Your shoes should conform to the shape of your feet without squeezing or pressing any part of your foot. Avoid pointy-toed shoes.
An Achilles Tendon Rupture is a traumatic event that needs appropriate treatment by your physician. The rupture can either be partial or complete depending on the severity. A thorough evaluation needs to be made to differentiate a tendonitis from a rupture and to evaluate the extent of the rupture.
The exact cause of Achilles tendon ruptures is hard to say. It can happen suddenly, without warning, or following an Achilles tendonitis . It seems that weak calf muscles may contribute to problems. If the muscles are weak and become fatigued, they may tighten and shorten. Overuse can also be a problem by leading to muscle fatigue . The more fatigued the calf muscles are, the shorter and tighter they will become. This tightness can increase the stress on the Achilles tendon and result in a rupture. Additionally, an imbalance of strength of the anterior lower leg muscles and the posterior lower leg muscles may also put an athlete at risk for an injury to the Achilles tendon. An Achilles tendon rupture is more likely when the force on the tendon is greater than the strength of the tendon. If the foot is dorsiflexed while the lower leg moves forward and the calf muscles contract, a rupture may occur. Most ruptures happen during a forceful stretch of the tendon while the calf muscles contract. Other factors that may increase the risk of Achilles tendon rupture include. Tight calf muscles and/or Achilles tendon. Change in running surface eg: from grass to concrete. Incorrect or poor footwear. A change of footwear eg: from heeled to flat shoes. It is thought that some medical conditions, such as gout, tuberculosis and systemic lupus erythematosus, may increase the risk of Achilles tendon rupture.
Tendon strain or tendon inflammation (tendonitis) can occur from tendon injury or overuse and can lead to a rupture. Call your doctor if you have signs of minor tendon problems. Minor tenderness and possible swelling increases with activity. There is usually no specific event causing sudden pain and no obvious gap in the tendon. You can still walk or stand on your toes. Acute calf pain and swelling can indicate a tear or partial tear of the Achilles tendon where it meets the calf muscle. You may still be able to use that foot to walk, but you will need to see a specialist such as an orthopedic surgeon. Surgery is not usually done for partial tears. Sometimes special heel pads or orthotics in your shoes may help. Follow up with your doctor to check for tendonitis or strain before resuming activity, because both can increase the risk of tendon rupture. Any acute injury causing pain, swelling, and difficulty with weight-bearing activities such as standing and walking may indicate you have a tear in your Achilles tendon. Seek prompt medical attention from your doctor or emergency department. Do not delay! Early treatment results in better outcome. If you have any question or uncertainty, get it checked.
Your doctor will ask you about your symptoms and examine you. He or she may also ask you about your medical history. Your doctor may ask you to do a series of movements or exercises to see how well you can move your lower leg. He or she may also examine your leg, heel and ankle and may squeeze your calf muscle to check the movement of your foot. You may need to have further tests to confirm if your tendon is torn, which may include the following. An ultrasound scan. This uses sound waves to produce an image of the inside of your leg. An MRI scan. This uses magnets and radio waves to produce images of the inside of your leg.
Non Surgical Treatment
Once a diagnosis of Achilles tendon rupture has been confirmed, a referral to an orthopaedic specialist for treatment will be recommended. Treatment for an Achilles tendon rupture aims to facilitate the torn ends of the tendon healing back together again. Treatment may be non-surgical (conservative) or surgical. Factors such as the site and extent of the rupture, the time since the rupture occurred and the preferences of the specialist and patient will be considered when deciding which treatment will be undertaken. Some cases of rupture that have not responded well to non-surgical treatment may require surgery at a later stage. The doctor will immobilise the ankle in a cast or a special hinged splint (known as a ?moon boot?) with the foot in a toes-pointed position. The cast or splint will stay in place for 6 - 8 weeks. The cast will be checked and may be changed during this time.
Surgery offers important potential benefits. Besides decreasing the likelihood of re-rupturing the Achilles tendon, surgery often increases the patient?s push-off strength and improves muscle function and movement of the ankle. Various surgical techniques are available to repair the rupture. The surgeon will select the procedure best suited to the patient. Following surgery, the foot and ankle are initially immobilized in a cast or walking boot. The surgeon will determine when the patient can begin weight bearing. Complications such as incision-healing difficulties re-rupture of the tendon, or nerve pain can arise after surgery.
