Overview
A bunion is a bony lump on the side of your foot, which develops when your big toe starts to angle towards your second toe. The bunion will eventually cause you discomfort and pain. The skin over the lump can become red, blistered or infected. A fluid-filled space called a bursa may also develop under your skin in this area and this can be painful if it becomes inflamed. This is called bursitis. The deformity of your big toe combined with a bunion is sometimes referred to as hallux valgus. Causes The causes of bunions are "multifactorial". In other words generally many things contribute to their occurence. Shoewear per se is a contributory factor but it isn't possible to say that the type of shoewear is necessairily relevant. Often there is a hereditary component with other family members also suffering with the same condition. Symptoms With Bunions, a person will have inflammation, swelling, and soreness on the side surface of the big toe. Corns most commonly are tender cone-shaped patches of dry skin on the top or side of the toes. Calluses will appear on high-pressure points of the foot as thick hardened patches of skin. Diagnosis The doctor considers a bunion as a possible diagnosis when noting the symptoms described above. The anatomy of the foot, including joint and foot function, is assessed during the examination. Radiographs (X-ray films) of the foot can be helpful to determine the integrity of the joints of the foot and to screen for underlying conditions, such as arthritis or gout. X-ray films are an excellent method of calculating the alignment of the toes when taken in a standing position. Non Surgical Treatment Wearing the right shoes, using shoe inserts (orthoses) and padding, and taking painkillers can all help to ease your symptoms of a bunion. However, these treatments can?t cure a bunion or stop it getting worse. If you have severe pain or discomfort from a bunion, you may be advised to have an operation to correct it. One of the most important things you can do is to wear the right footwear. You should try to wear flat, wide-fitting shoes with laces or an adjustable strap that fits you properly. You may also want to place a bunion pad over your bunion to give it some protection from the pressure of your shoes. You can usually buy these pads from a pharmacy, or get them from your podiatrist or chiropodist. He or she may also recommend a shoe insert, which can be moulded specifically to your foot. Shoe inserts aim to reduce the pain of your bunion by improving how you walk. You can take over-the-counter painkillers, such as paracetamol or ibuprofen, to help relieve the pain and inflammation of your bunion. Always follow the instructions in the patient information leaflet that comes with your medicine. Medicines give temporary relief but they won?t be able to cure your bunion or prevent it from getting worse. If you have a bunion as a result of underlying arthritis, your doctor may prescribe specific medicines to treat this. Surgical Treatment If these methods fail, then surgery may be suggested. Basically, bunion surgery is performed to improve function or to prevent pain from occurring. When surgery is delayed in a symptomatic foot, greater amounts of arthritis can develop and the more complicated surgery can become. Surgery is performed to improve alignment and function to the big toe joint. The large bump is removed and, sometimes, a cut is made into the bone, to move it to a more normal position. Screws, pins and wires can be used beneath the skin, to improve healing and results. Healing can range from 3-12 weeks, depending on the procedure. Prevention To help prevent bunions, select your style and size of shoes wisely. Choose shoes with a wide toe area and a half-inch of space between the tip of your longest toe and the end of the shoe. Shoes also should conform to the shape of your feet without causing too much pressure.
Overview
The Achilles tendon is a conjoined tendon composed of the gastrocnemius and soleus muscles with occasional contribution from the plantaris muscle, and it inserts on the calcaneal tuberosity. The plantaris muscle is absent in 6% to 8% of individuals. The Achilles tendon is approximately 15-cm long and is the largest and strongest tendon in the human body. The tendon spirals approximately 90 from its origin to its insertion and this twisting produces an area of stress approximately 2- to 5-cm proximal to its insertion. The tendon has no true synovial sheath; instead it is wrapped in a paratenon. The Achilles tendon experiences the highest loads of any tendon in the body, and bears tensile loads up to 10 times body weight during athletic activities. The tendon most commonly ruptures in a region 2- to 6-cm proximal to its insertion. Causes An Achilles tendon rupture is often caused by overstretching the tendon. This typically occurs during intense physical activity, such as running or playing basketball. Pushing off from the foot while the knee is straight, pivoting, jumping, and running are all movements that can overstretch the Achilles tendon and cause it to rupture. A rupture can also occur as the result of trauma that causes an over-stretching of the tendon, such as suddenly tripping or falling from a significant height. The Achilles tendon is particularly susceptible to injury if it is already weak. Therefore, individuals who have a history of tendinitis or tendinosis are more prone to a tendon rupture. Similarly, individuals who have arthritis and overcompensate for their joint pain by putting more stress on the Achilles tendon may also be more susceptible to an Achilles tendon rupture. Symptoms It is important to know that pain at the back of the heel is not always due to Achilles tendon rupture. It may be due to bursitis (fluid accumulation in the heel due to repeated irritation) and tendonitis (pain along the Achilles tendon due to constant friction and irritation). The above disorders tend to improve with use of pain medications and rest, whereas Achilles tendon rupture requires surgery and/or a cast. Diagnosis Laboratory studies usually are not necessary in evaluating and diagnosing an Achilles tendon rupture or injury, although evaluation may help to rule out some of the other possibilities in the differential diagnosis. Plain radiography. Radiographs are more useful for ruling out other injuries than for ruling in Achilles tendon ruptures. Ultrasonography of the leg and thigh can help to evaluate the possibility of deep venous thrombosis and also can be used to rule out a Baker cyst, in experienced hands, ultrasonography can identify a ruptured Achilles tendon or the signs of tendinosis. Magnetic resonance imaging (MRI). MRI can facilitate definitive diagnosis of a disrupted tendon and can be used to distinguish between paratenonitis, tendinosis, and bursitis. Non Surgical Treatment Medical therapy for a patient with an Achilles tendon rupture consists of rest, pain control, serial casting, and rehabilitation to maximize function. Ongoing debate surrounds the issue of whether medical or surgical therapy is more appropriate for this injury. Conservative management of Achilles tendinosis and paratenonitis includes the following. Physical therapy. Eccentric exercises are the cornerstone of strengthening treatment, with most patients achieving 60-90% pain relief. Orthotic therapy in Achilles tendinosis consists of the use of heel lifts. Nonsteroidal anti-inflammatory drugs (NSAIDs). Tendinosis tends to be less responsive than paratenonitis to NSAIDs. Steroid injections. Although these provide short-term relief of painful symptoms, there is concern that they can weaken the tendon, leading to rupture. Vessel sclerosis. Platelet-rich plasma injections. Nitric oxide. Shock-wave therapy. Surgical Treatment Some surgeons feel an early surgical repair of the tendon is beneficial. The surgical option was long thought to offer a significantly smaller risk of re-rupture compared to traditional non-operative management (5% vs 15%). Of course, surgery imposes higher relative risks of perioperative mortality and morbidity e.g. infection including MRSA, bleeding, deep vein thrombosis, lingering anesthesia effects, etc. Prevention Good flexibility of the calf muscles plays an essential role in the prevention of Achilles tendon injuries. It is also important to include balance and stability work as part of the training programme. This should include work for the deep-seated abdominal muscles and for the muscles that control the hip. This might at first appear odd, given the fact that the Achilles are a good distance from these areas, but developing strength and control in this area (core stability) can boost control at the knee and ankle joints. Training errors should be avoided. The volume, intensity and frequency of training should be monitored carefully, and gradually progressed, particularly when introducing new modes of training to the programme. Abrupt changes in training load are the primary cause of Achilles tendinopathy. |
