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.
Any injury or disease of the hip will adversely affect the joint's range of motion and ability to bear weight.
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.
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.
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 Labral Tear
A hip labral tear is an injury to the labrum, the cartilage that surrounds the outside rim of your hip joint socket. The hip joint is a ball and socket joint in which the head of the femur is the ball and the pelvic acetabulum forms the socket. The labrum helps to deepen the socket and provide stability to the joint. It also acts as a cushion and enables smooth movements of the joint.
Chondral Lesions or Injuries
The hip joint is one of the largest weight-bearing joints in the body, formed by the thigh bone or femur and the acetabulum of the pelvis. It is a ball and socket joint with the head of the femur as the ball and the pelvic acetabulum forming the socket. The joint surface is covered by a smooth articular cartilage which acts as a cushion and enables smooth movements of the joint. A chondral injury refers to an injury of the articular cartilage, covering the joint.
The hip plays an important role in supporting the upper body weight while standing, walking and running, and hip stability is crucial for these functions. The femur (thigh bone) and acetabulum (hip bone) join to form the hip joint, while the labrum (tissue rim that seals the hip joint) and the ligaments lining the hip capsule maintain the stability of the hip. Injury or damage to these structures can lead to a condition called hip instability. Hip instability happens when the hip joint becomes unstable causing various symptoms.
Loose bodies are small loose fragments of cartilage or a bone that float around the joint. The loose bodies can cause pain, swelling, locking and catching of the joint. Loose bodies occur if there is bleeding within the joint, death of tissues lining the joints associated with tuberculosis, osteoarthritis, and rheumatoid arthritis. Other causes include fractures, trauma, bone and cartilage inflammation, and benign tumors of the synovial membrane.
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 Abductor Tears
Hip abductors are a major group of muscles found in the buttocks. It includes the gluteus maximus, gluteus medius, gluteus minimus, and tensor fascia lata muscles.
The Gluteus medius arises at the top of the pelvic bone and runs to attach on the outer side of the thighbone or femur. The muscle controls side-to-side movement of the hip and stabilizes hip movement.
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.
Tendons are strong connective tissue structures that connect muscle to bone. Hip tendonitis is a condition associated with degeneration of the hip tendons. This condition is mainly caused due to strain on the tendons which may be due to overuse, or biomechanical problems.
The hip joint consists of 2 bones, the hip bone and the leg bone. An injury or bruise to one of these bones or the surrounding muscles or tissues is termed a hip pointer. This type of injury is mainly caused due to a sudden blow or hit on the hip which can occur from sports activities such as football, rugby, volleyball, basketball, cycling or skating.
Developmental dysplasia of the hip (DDH) or Hip dysplasia is a condition which is seen in infants and young children because of developmental problems in the hip joint. The femur (thigh bone) partially or completely slips out of the hip socket causing dislocation at the hip joint. It is most common in first born baby with family history of the disorder.
Legg-Calve-Perthes Disease (LCPD) or Perthes disease is a disorder of the hip that affects children, usually between the ages of 4 and 10. It usually involves one hip, although it can occur on both sides in some children. It occurs more commonly in boys than girls.
Slipped Capital Femoral Epiphysis
Slipped capital femoral epiphysis (SCFE) is an unusual disorder of the hip where the ball at the upper end of the thigh bone (femur) slips in a backward direction. This is caused due to weakness of the growth plate. This condition is commonly caused during accelerated growth periods such as the onset of puberty.
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.
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.
Hip joint injections involve injecting medicine directly into the hip joint to diagnose the source of pain or treat pain due to conditions such as arthritis, injury or mechanical stress of the hip joint. Hip pain may be experienced in the hip, buttock, leg or low back. The injection contains a combination of a numbing medicine and cortisone (an anti-inflammatory agent). Numbing medicine delivers temporary relief from pain, provided the hip joint is the source of the pain.
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.
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.
Arthroscopy, also referred to as keyhole or minimally invasive surgery, is a procedure in which an arthroscope is inserted into a joint to check for any damage and repair it simultaneously.
An arthroscope is a small, fiber-optic instrument consisting of a lens, light source, and video camera. The camera projects an image of the inside of the joint onto a large screen monitor allowing the surgeon to look for any damage, assess the type of injury, and repair the problem.
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.
