A positive Trendelenburg's sign is caused by weakness or ineffective action of the abductor muscles of the lower limb, the gluteus medius muscle and the gluteus minimus muscle. [ 2 ] Damage to the motor nerve supply of the lateral gluteal muscles (gluteus medius muscle and gluteus minimus muscle)
Also called the side-lying position, it is like the jackknife except the patient is on his or her side. Other similar positions are Lateral chest and Lateral kidney. Lloyd-Davies position It is a medical term referring to a common position for surgical procedures involving the pelvis and lower abdomen.
During the stance phase, or when standing on one leg, the weakened abductor muscles (gluteus medius and minimus) on the side of the supporting leg allow the opposite hip to droop. To compensate, the trunk lurches to the weakened side to maintain the center of gravity over the supporting leg. This produces a characteristic "waddling" gait.
The lateral border (radial side) is a pair of parallel and intimate tendons, of the extensor pollicis brevis and the abductor pollicis longus. [2] Accordingly, the anatomical snuffbox is most visible, having a more pronounced concavity, during thumb extension .)
The abductor digiti minimi is the most variable hypothenar muscle, [4] and might be joined by accessory slips from the tendon of the flexor carpi ulnaris, the flexor retinaculum, the fascia of the distal forearm, or the tendon of the palmaris longus. Occasionally, the muscle is partially inserted onto the fifth metacarpal bone. [5]
A tendon transfer is a surgical process in which the insertion of a tendon is moved, but the origin remains in the same location. Tendon transfer involves redistribution of muscle power, not recreation. Tendons are transferred at the distal attachment from lesser to more important functions so that the overall function is improved.
Furthermore, PeekMed allows the surgeon to edit the planning and to simulate different outcomes of the procedure. One of the features of this ultimate technology, automatic orthopedic templating helps the surgeon by automatically placing the most suitable template in the correct position with extreme accuracy.
In human anatomy, the adductor hiatus also known as hiatus magnus is a hiatus (gap) between the adductor magnus muscle and the femur that allows the passage of the femoral vessels from the anterior thigh to the posterior thigh and then the popliteal fossa. [1]
