The hip joint functions as one of the most important joints in the human body. Designed for both mobility and stability, the hip allows the entire lower extremity to move in three planes of motion, while providing an important shock absorption function to the torso and upper body. view
Trauma is the term used to describe injury. Trauma is classified by its severity depending on the amount of force used to cause the injury. view
Hip fractures are breaks in the upper part of the thigh bone (femur) and are the second-most common break in the human body after wrist fractures under the age of 75 years and the most common fracture after 75 years of age. view
A hip dislocation is classified according to the direction of the dislocation (anterior, posterior, superior, inferior), the amount of force it took to dislocate the hip, whether it is accompanied by a fracture (fracture/dislocation), and whether or not the patient has had a previous hip replacement on the affected side. view
Thigh bone (femur) fractures usually occur in younger patients after high speed injuries such as motor vehicle and motorcycle accidents. view
Compartment syndrome is an orthopedic emergency. Thigh compartment syndrome occurs when the pressure in the front, back, or inner thigh compartments rises above the blood pressure needed for the heart to pump blood to the thigh. view
Hip arthritis is the loss of the cartilage cushion in the joint contact surfaces that normally allows for smooth, pain-free gliding during hip motion. view
A bursa is a fluid-filled sac of tissue that helps tendons slide over themselves as well as over and around bones. view
A hip/thigh strain, by definition, is an injury to a muscle or muscles around the hip and thigh. These injuries can be caused by one specific injury, such as a fall or while playing sports, or by repetitive micro-trauma over time, often referred to as overuse injuries. view
Hip arthritis is the loss of the cartilage cushion in the joint contact surfaces that normally allows for smooth, pain-free gliding during hip motion. When arthritis occurs, the patient presents with the following symptoms: hip pain with all activities, especially getting out of a car and tying shoes, a grinding noise with hip movement called crepitance, decreased motion and overall limited function. Arthritis of the hip can have several causes. When arthritis results from wear and tear over time, as occurs with aging, it is called osteoarthritis or degenerative arthritis. When a fracture or broken bone extends into the joint and heals improperly or a joint dislocation injures the joint cartilage, it is called post-traumatic arthritis. Arthritis that occurs at a younger age (less than 40 yrs) is rare and commonly due to genetic causes that are inherited. Arthritis can be caused by infection or inflammatory conditions such as rheumatoid arthritis, lupus, psoriatic arthritis, or from various crystalline diseases. These crystalline diseases, called gout or pseudo-gout, result from inflammatory cells in the body attempting to clean up invading particles and in the process, destroy the joint inadvertently. When there is loss of blood supply to the top of the thigh bone (femur), it is referred to as avascular necrosis (AVN), and occurs from a variety of causes. Severe fractures of the upper end of the femur may disrupt the blood supply to the femoral head, resulting in collapse of the femoral head and loss of its smooth shape and cartilage surface.
When hip joint arthritis is treated surgically, it is treated with a total hip joint replacement. Joint replacements are referred to as arthroplasties and in this instance it is called a total hip arthroplasty. A total hip arthroplasty is done when both sides of the joint have arthritis and both the thigh bone (femoral head) and socket (acetabulum) are replaced. There are many companies that make hip replacement implants and the surgeon will select the one he or she has the most experience with and which gives a reliable result, based on the reported outcomes in the orthopedic literature. After surgery, therapists work with the patient to start moving the hip, working on strengthening the muscles around the hip and leg, and to begin walking again. Most patients are able to return to their activities with or without limitations, based on their pre-injury level of ambulation and function.
