A Lisfranc (midfoot) injury is a significant injury that often has a prolonged recovery time. Fracture of the midfoot bones and/or disruption of the midfoot ligaments (Figure 1) leads to pain, swelling, and often an inability to weight-bear. During normal standing and walking the ligaments of the midfoot are subject to forces that are 2-3 times body weight.
What is lisfranc injury
The Lisfranc fracture is a fracture of the foot in which one or all of the metatarsals are displaced from the tarsus. It is named after 18th- and 19th-century surgeon and gynecologist Jacques Lisfranc de St. Martin. This type of injury classically occurred when a horseman fell while riding, having trapped his foot in the stirrup or fallen into a drain. At present, such an injury happens typically in activities such as windsurfing (where participants' feet are in foot straps that pass over the metatarsals), or when one steps into a hole and the foot twists heavily. Falling from a height of two or three stories can also cause this fracture. American football players occasionally get this injury, often when they have their foot pointing down and someone lands on their heel.
A Lisfranc injury is initially diagnosed based on the history and description of the athlete’s acute injury. Often an athletic trainer at the practice or competition may see the injury occur in real time and have an immediate suspicion for the injury. The athlete will describe the immediate onset of pain in the midfoot region. There may be difficulty or even an inability to put weight on the injured foot. Over the course of the ensuing day, swelling and bruising often occurs that when serious may even become evident on the bottom of the foot. On a physical exam, the injured athlete will be tender over Lisfranc’s joint and any others involved in the injury. In the most severe of injuries, those that involve a large direct crushing force to the foot, the swelling may be so severe that an emergent evaluation in an emergency room is necessary and possibly even immediate surgery. This is however extremely rare in the setting of athletic injuries.
Lisfranc injury recovery time
Most often the treatment of a Lisfranc injury is surgical, although some minor injuries can be treated conservatively. If there is minimal displacement of the bones, a stiff walking cast applied for approximately eight weeks is an appropriate alternative. However, the more common treatment is to secure the fractured and dislocated bones with either internal (screws) or external (pins) fixation.
Stable Lisfranc injuries that do not require surgery may cause an athlete to miss 2 months or more of their season. However, most athletes are able to successfully return at some point. Those injuries that are unstable, and require surgical repair, are serious injuries that almost always cause the injured athlete to miss the remainder of their season. It is also not uncommon for a high level athlete to not be able to return to the same level of athletic performance even in following seasons. Two well-known examples are Eric Rhett and Duce Staley both of whom had surgery for a serious Lisfranc injury and never successfully returned to their pre-injury form.
Teenage Acne Treatment Girls Are you looking for teenage acne treatment for girls? Acne is caused when a hair follicle get clogged with an oil called sebum and skin cells. Skin bacteria thrive and multiply in sebum, causing inflammation. Some acne consists of simple blackheads and whiteheads. Inflammation within the pore causes a pimple (also called a “papule”) or a pus-filled pimple (“pustule”), depending on how deep it is. If it’s really deep, it can cause a painful cyst and scarring.
Psoriasis Symptoms and Treatment Psoriasis is common, affecting 1.5-2.0% of the population. It affects all ages, with bimodal peaks of incidence at ages 20-30 and 50-60 years. Plaque-type psoriasis is easily identified by its discrete round orange-red plaques with silver scale on the scalp, elbows, knees, or trunk. When psoriasis appears as intertriginous, guttate, or nail-limited psoriasis, the diagnosis can be challenging.
Etiology. Psoriasis exhibits abnormalities of epidermal proliferation and migration of inflammatory cells, resulting in accelerated epidermal turnover time. Psoriasis, particularly extensive psoriasis, has a strong genetic component. Exacerbants of psoriasis include stress, probably alcohol, many drugs, infection, and steroids.
Arrhythmias Treatment and Types A disturbance in the rhythm of the heart is termed arrhythmia and can range from a mild “skipped beat” to a life-threatening failure to pump. The later is called ventricular fibrillation, and it is the most common cause of cardiac arrest, in which the heart suddenly stops beating. Death can follow in minutes unless medical help is provided immediately. People who have had a heart attack or who are elderly are at a much higher risk of developing a life-threatening arrhythmia.
In ventricular fibrillation, the heart’s electrical activity becomes disordered. As a result, the heart’s lower (pumping) chambers rapidly contract in an unsynchronized way. In effect, the ventricles flutter rather than beat, and the heart pumps little or no blood. Symptoms may include palpitations, lightheadedness, chest discomfort, shortness of breath, or loss of consciousness. If a more normal rhythm is not restored within three to five minutes, the patient will suffer brain and heart damage and will die.
Exactly who does smoking affect baby Cigarette smoking produces a number of abnormalities in a mother’s body. First, cyanide (a strong poison) is produced from smoking. This by product from smoking goes directly to your tissue and to the tissue of your baby, producing hypoxia (lack of oxygen) in the individual cell. In addition to this, nicotine causes constriction of the boob vessels of your body, decreasing the amount of blood flowing through the placenta and adding to the hypoxia produced by the cyanide.
Recognizing Warning Signs of Stroke Stroke is a general term for a wide variety of crises (sometimes called cerebrovascular accidents [CVAs] or brain attacks) the result from blood vessel damage in the brain. African Americans have a much greater risk of stroke than white American do, probably because African Americans have greater likelihood of having hypertension than white Americans. Data for 1998 indicate that 158,448 deaths and half a million new cases of stroke occurred. Just as the heart muscle needs adequate blood supply, so does the brain. Any disturbance in the proper supply of oxygen and nutrients to the brain can pose a threat.
Perhaps the most common form of stroke results from the blockage of a cerebral (brain) artery. Similar to coronary occlusions, cerebrovascular occlusions can be started by a clot that travels from another part of the body to the brain, called an embolus. The resultant accidents (cerebral thrombosis or cerebral embolism) cause between 80% and 90% of all strokes. The portion of the brain deprived of oxygen and nutrients can literally die.
Crystal arthritis We are going to start out with gout, which is a thing to remember, it is a different disease for both male and female. Men tend to present at a younger age because of the association with uric acid and antigen levels in the blood. Some are between the ages of 35 and 55, is the average onset of gout in a male patient. Usually it presents as an acute podagra, which is the great toe or possibly a knee or an ankle depending upon the saturation of the soft tissue with uric acid.
Molar Pregnancy Molar pregnancies, invasive molar pregnancies, and malignant molar pregnancies are growths that result from abnormal pregnancies referred to as trophoblastic disease. Doctors often use the term mole to describe some of these problems; this has nothing whatever to do with a mole on the surface of the skin. The term trophoblastic disease is derived from the name of the trophoblast cell, the cell that makes up the placenta.
Food Borne Illness Prevention Most of us have experienced the characteristic symptoms of diarrhea, nausea, cramping, and vomiting that prompt us to say, “It must be something I ate.” The number of cases of food poisoning in the United States has been growing (there are three millions of cases per year), which has prompted the Food and Drug Administration to make prevention of food contamination a high priority. Deaths in Pacific Northwest in 1994 attributed to consumption of Jack-in-the-Box hamburgers contaminated with Escherichia coli, a bacterial agent, increased people’s fears about the overall safety of meat, poultry and seafood.
Lyme Disease Symptoms and Treatment Lyme disease was first recognized in this country in 1975 along this rural road in the region of Lyme Connecticut. Physicians were facing an epidemic of what was being called juvenile rheumatoid arthritis. But it was through the pioneering work of Dr. Stear, who had been at Yale University, and Stira Malavista where it became very apparent that this was not a disease that was isolated to a joint, but rather involved many other systems in the body with the predilection for the skin, for the heart and the nervous system in addition to the joints. Although Lyme disease was relatively new to the United States, the neurologic manifestations were well recognized in Europe at the turn of the century and had been associated with the bite of the hard-shelled tick of the Ixodes family. But it wasn’t until 1981 that Willie Burgdorfer collected Ixodes from an endemic area of Lyme disease in the United States and isolated the spirochete Borrelia burgdorferi, which bears his name. In 1983 Stira Malavista established the spirochete etiology of Lyme disease when they cultured the spirochete from the blood of patients and other tissues of patients with acute Lyme disease and showed the sera converted to spirochete protein.
Tinnitus Treatment 2011 A person with tinnitus hears noise in one or both ears even in the absence of actual external sound. This condition brings with it many side problems other than the obvious discomfort of the phantom sound. It is s usually accompanied by dizziness, loss of balance, insomnia, hearing difficulties, depression, anxiety, and other similar issues. For somebody with this condition, finding a tinnitus treatment becomes imperative.
Cymothoa Exigua in Human and Life Cycle Cymothoa exigua is a tiny crustacean that sneaks up on a fish (specifically, a red snapper) and works its way in through the gills. Typical parasite behavior so far.
Then it attaches itself to the base of the fish's tongue, the tongue evidently being the tastiest part of the fish (get it!?). The parasite uses its claws to dig into the tongue and drink the fish's blood--and that's just the beginning
