The hip joint is the largest weight-bearing joint in the human body. It is also referred to as a ball and socket joint and is surrounded by muscles, ligaments, and tendons. The thigh bone or femur and the pelvis join to form the hip joint.
Hip Injuries and Tears
The hip is an important joint that helps us walk, run and jump. The ball-and-socket joint in the hip is formed between the round end of the femur (thighbone) and the cup-shaped socket of the acetabulum (part of the hip bone). Joint stability in the hip region is achieved through the labrum (a strong fibrous cartilage), which covers the acetabulum and seals it, and ligaments (tissue connecting bone to bone) and tendons (tissue connecting muscle to bone) that encase the hip and control the hip movements.
Hip pain, one of the common symptoms patients complain of, may not always be felt precisely over the hip joint. Pain may be felt in and around the hip joint and the cause for pain is multifactorial. The exact position of your hip pain suggests the probable cause or underlying condition causing pain. Pain felt inside the hip joint or your groin area is more likely to be because of the problems within the hip joint.
A tear in the muscle fibers caused by either a fall or direct blow to the muscle, overstretching and overuse injury is called a strain. Muscle strains often occur in the hip region whenever a muscle contracts suddenly from its stretched position. It can be mild, moderate or severe and depends on the level of injury. The chances of having a hip muscle strain becomes high if you have had a previous injury in the area or if there is no warm-up before exercising. The most common symptom of hip strain is pain and swelling in the area of injury. Pain may worsen on using the injured muscle and the strength in the muscle may also decrease.
Hip bursitis is a painful condition caused by inflammation of a bursa in the hip. Bursae are fluid filled sacs present in joints between bone and soft tissue to reduce friction and provide cushioning during movement.
Femoroacetabular impingement (FAI) is a condition where there is too much friction in the hip joint from bony irregularities causing pain and decreased range of hip motion. The femoral head and acetabulum rub against each other creating damage and pain to the hip joint. The damage can occur to the articular cartilage (the smooth white surface of the ball or socket) or the labral tissue (the lining of the edge of the socket) during normal movement of the hip.
Avascular necrosis, also called osteonecrosis is a condition in which bone death occurs because of inadequate blood supply to it. Lack of blood flow may occur when there is a fracture in the bone or a joint dislocation that may damage nearby blood vessels. Chronic use of high doses of steroid medications and heavy alcohol consumption are the two main risk factors of avascular necrosis. Initially, small breaks appear in the bone that may eventually collapse. Hip joint is most commonly affected; however, the knee and shoulder may also be involved.
The hip joint is a “ball and socket” joint. The “ball” is the head of the femur, or thigh bone, and the “socket” is the cup shaped acetabulum. The joint surface is covered by a smooth articular surface that allows pain free movement in the joint.
The hip joint is a ball and socket joint. The “ball” is the head of the femur, or thigh bone, and the “socket” is the cup shaped acetabulum. The joint is surrounded by muscles, ligaments, and tendons that support and hold the bones of the joint in place. Hip dislocation occurs when the head of the femur moves out of the socket. The femoral head can dislocate either backward (posterior dislocation) or forward (anterior dislocation).
Gluteus Medius Tear
A gluteus medius tear is a condition characterized by severe strain on the gluteus medius muscle that results in partial or complete rupture of the muscle.
The gluteus medius is one of the major muscles of the hip and is essential for movement of the lower body and keeping the pelvis level during ambulation. The gluteus medius muscle arises from the top of the pelvic bone and attaches to the outer side of the thigh bone or femur at the greater trochanter by the gluteus medius tendon.
Hip Groin Disorders
Hip and groin disorders are more common in athletes, caused by rapid acceleration and deceleration motion.
The rehabilitation time for hip and groin injuries are longer than most other injuries, therefore early and accurate diagnosis is essential. The management of hip and groin injuries is complex due to the presence of multiple anatomic structures in that region. Moreover, the signs and symptoms of most hip and groin disorders are similar making the diagnosis difficult.
The hip joint is one of the most important and flexible joints in the human body which allows us to walk, run, bend and perform physical activities. It is a ball (femoral head) and socket joint formed between the hip bone and femur (thigh bone). The hip joint is surrounded by strong muscles and tough ligaments that prevent dislocation of the hip. The hip joint allows a greater range of motion of your body and hence is subjected to wear and tear.
Subtrochanteric Hip Fracture
A hip fracture is a break that occurs near the hip in the upper part of the femur or thigh bone. The thigh bone has two bony processes on the upper part - the greater and lesser trochanters. The lesser trochanter projects from the base of the femoral neck on the back of the thigh bone. Hip fractures can occur either due to a break in the femoral neck, in the area between the greater and lesser trochanter or below the lesser trochanter.
Hip synovitis, also called transient hip synovitis or toxic synovitis is a condition in which there is inflammation of the synovial tissues surrounding the hip joint causing hip pain. It is the most common reason for sudden hip pain occurring in young children between the age of 2 and 9. It affects boys more commonly than girls and most of the times, the hip joint on only one side is affected.
Irritable hip, also known as acute transient synovitis, is a common disorder of childhood characterized by onset of hip pain and limping. The term transient means that it does not usually last long. It usually occurs before puberty and affects only one hip. Boys aged between 4 to 10 years are most often affected 2 to 4 times more than girls.
Osteoarthritis of the Hip
Osteoarthritis, also called degenerative joint disease is the most common form of arthritis. It occurs most often in older people. This disease affects the tissue covering the ends of bones in a joint (cartilage). In a person with osteoarthritis, the cartilage becomes damaged and worn out causing pain, swelling, stiffness and restricted movement in the affected joint. Although osteoarthritis may affect various joints including hips, knees, hands, and spine, hip joint is most commonly affected. Rarely, the disease may affect the shoulders, wrists and feet.
Inflammatory Arthritis of the Hip
Inflammation of the joints is referred to as arthritis. The inflammation arises when the smooth covering (cartilage) at the end surfaces of the bones wears away. In some cases, the inflammation is caused when the lining of the joint becomes inflamed as part of an underlying systemic disease. These conditions are referred to as inflammatory arthritis.
Transient Osteoporosis of the Hip
Transient osteoporosis of the hip is a rare condition that causes bone loss temporarily in the upper part of the thighbone (femur). It is mostly found in young or middle aged men between the ages of 30 and 60, and women in their later stages of pregnancy or early postpartum period (following childbirth). It is characterized by abrupt onset of pain that increases with activity.
Physiotherapy or physical therapy is an exercise program that helps you to improve movement, relieve pain, encourage blood flow for faster healing, and restore your physical function and fitness level. The main aim of physical therapy is to make your daily activities, such as walking, getting in and out of bed, or climbing stairs, easier. It can be prescribed as an individual treatment program or combined with other treatments. Physiotherapy is usually ordered to help you recover after certain surgeries, injuries and long-term health problems such as arthritis.
Platelet Rich Plasma Therapy
Our blood consists of a liquid component known as plasma. It also consists of three main solid components which include the red blood cells (RBCs), white blood cells (WBCs), and platelets. Platelets play an important role in forming blood clots. They also consist of special proteins, known as growth factors, which help with our body’s healing process. Platelet-rich plasma or PRP is a high concentration of platelets and plasma.
Shock wave therapy is application of the sound waves to treat musculoskeletal conditions and sports-related injuries. It is an effective treatment for trochanteric bursitis. Trochanter bursitis also called hip bursitis or greater trochanter bursitis is a common problem caused by inflammation of the bursa that overlies the greater trochanter (bony prominence at the outer side of the hip). The condition causes pain in the outer portion of the upper thigh. Greater trochanter bursitis most commonly affects runners and athletes participating in soccer and football.
Hip Preservation Surgery
The hip is a ball and socket joint comprising of the femur (thigh bone) and the pelvic bone. The head of the femur (ball) articulates with a cavity (socket) called the acetabulum in the pelvic bone. To facilitate smooth and frictionless movement of the hip joint, the articulating surfaces of the femur head and acetabulum are covered by spongy articular cartilage. Injury, wear-and-tear and certain diseases can result in the wearing away of the cartilage tissue, causing painful rubbing of bones.
Hip implants are artificial devices that form the essential parts of the hip joint during a hip replacement surgery. The hip implants vary by size, shape, and material. Implants are made of biocompatible materials that are accepted by the body without producing any rejection response. Implants can be made of metal alloys, ceramics, or plastics, and can be joined to the bone. The metals used include stainless steel, titanium, and cobalt chrome, whereas the plastic used is polyethylene. Various components of a hip implant may be used for a hip replacement surgery.
Core Decompression for Avascular Necrosis of the Hip
The hip joint is a ball and socket joint, where the head of the thigh bone (femur) articulates with the cavity (acetabulum) of the pelvic bone.
Sickle cell disease, a group of disorders that affect the hemoglobin or oxygen carrying component of blood, causes avascular necrosis or the death of bone tissue in the hip due to lack of blood supply.
The hip joint is one of the body's largest weight-bearing joints and is the point where the thigh bone (femur) and the pelvis (acetabulum) unite. It is a ball and socket joint in which the head of the femur is the ball and the pelvic acetabulum forms the socket. The joint surface is covered by a smooth articular cartilage that cushions and enables smooth movements of the joint.
The hip joint is also known as a ball and socket joint, where the ball (femoral head) of the thigh bone fits into the socket (acetabulum) of the pelvis bone.
Damage to the hip bones can be treated by hip resurfacing, which is a surgical procedure in which the damaged parts of the femoral head are trimmed, and the socket is removed and replaced with metal caps.
Health and Safety
Pre-op & Post-Op Hip Guidelines
Planning for your hip surgery prepares you for the operation and helps to ensure a smooth surgery and easier recovery. Here are certain pre-operative and post-operative guidelines which will help you prepare for hip surgery.
Caregivers Guide for the Hip
When your friend or loved one has undergone a hip replacement surgery, as a caregiver, you will play an important role in his/her recovery. There are various aspects you need to be aware of to ensure the safety, comfort and recovery of the patient.
Hip Fracture Prevention
Hip fractures refer to any kind of breakage or damage in the thigh bone (femur). People over the age of 65, especially women, are highly vulnerable to hip fractures. You will require assistance after hip fractures from family members as well as health professionals and may also be required to be admitted to the hospital for further assistance. Hip fractures can be caused due to weak bones (osteoporosis) or from a fall. Osteoporosis is due to various factors such as age, gender, nutrition, life style or heredity.
After Hip Replacement
Hip replacement is a surgery performed to replace parts of a diseased hip joint with an artificial prosthesis. The goal of hip replacement is to eliminate pain and return you to your normal activities. You can help in recovery and improve the outcomes of the procedure by following certain precautions and changing the way you carry out your daily activities.
