Many muscles contribute to these movements: The psoas is the primary hip flexor, assisted by the iliacus. The pectineus, the adductors longus, brevis, and magnus, as well as the tensor fasciae latae are also involved in flexion. The gluteus maximus is the main hip extensor, but the inferior portion of the adductor magnus also plays a role.
Acquired hand deformity refers to the structural or functional abnormalities that develop in the hand. There are multiple varying causes of acquired hand deformity, triggering significant consequences and complications. Trauma, including blunt force, penetrating injuries, burns, and sports-related incidents, is a primary cause of acquired hand ...
A hand imitating an ulnar claw. The metacarpophalangeal joints of the 4th and 5th fingers are extended and the Interphalangeal joints of the same fingers are flexed.. An ulnar claw, also known as claw hand or ‘Spinster’s Claw’, is a deformity or an abnormal attitude of the hand that develops due to ulnar nerve damage causing paralysis of the lumbricals.
The most commonly involved joints are the two near the ends of the fingers and the joint at the base of the thumbs, the knee and hip joints, and the joints of the neck and lower back. The symptoms can interfere with work and normal daily activities. Unlike some other types of arthritis, only the joints, not internal organs, are affected.
The muscles of the hand are the skeletal muscles responsible for the movement of the hand and fingers. The muscles of the hand can be subdivided into two groups: the extrinsic and intrinsic muscle groups. The extrinsic muscle groups are the long flexors and extensors. They are called extrinsic because the muscle belly is located on the forearm.
A hip dislocation is when the thighbone ( femur) separates from the hip bone ( pelvis ). [1] Specifically it is when the ball–shaped head of the femur ( femoral head) separates from its cup–shaped socket in the hip bone, known as the acetabulum. [1] The joint of the femur and pelvis ( hip joint) is very stable, secured by both bony and soft ...
The interphalangeal joints of the hand are the hinge joints between the phalanges of the fingers that provide flexion towards the palm of the hand . There are two sets in each finger (except in the thumb, which has only one joint): Anatomically, the proximal and distal interphalangeal joints are very similar. There are some minor differences in ...
Femoroacetabular impingement (FAI) is a condition involving one or more anatomical abnormalities of the hip joint, which is a ball and socket joint. [1] It is a common cause of hip pain and discomfort in young and middle-aged adults. [2] It occurs when the ball shaped femoral head contacts the acetabulum abnormally or does not permit a normal ...
