In this scale, muscle strength is graded on a scale from 0 to 5. For evaluating the strength of the intrinsic hand muscles, a small modification to the standard MRC grading has been made so that grade 3 indicates ‘full active range of motion’ as compared to ‘movement against gravity’: [2]
Swelling, deformity, tenderness, and loss of wrist motion are normal features on examination of a person with a distal radius fracture. "Dinner fork" deformity of the wrist is caused by dorsal displacement of the carpal bones (Colle's fracture). Reverse deformity is seen in volar angulation (Smith's fracture).
The physician may also test the range of motion by flexion, extension, radius, and ulna deviation, with normal ranges of 65-80 degrees of flexion, 55-75 degrees of extension, 30-45 degrees of ulna deviation, and 15-25 degrees of radius deviation. [4] Conventional radiography may be used for detection of wrist bone pathologies. [4]
Range of motion (or ROM) is the linear or angular distance that a moving object may normally travel while properly attached to another. In biomechanics and strength training , ROM refers to the angular distance and direction a joint can move between the flexed position and the extended position. [ 1 ]
Ulnar deviation, also known as ulnar drift, is a hand deformity in which the swelling of the metacarpophalangeal joints (the big knuckles at the base of the fingers) causes the fingers to become displaced, tending towards the little finger. [1]
The SL angle is an indicator of dorsal intercalated segment instability deformity (DISI). The SL angle goes between: [1] - A line through the long axis of the scaphoid bone. ...
In cases of minor wrist pain, CTS, arthritis, injuries and sprains, it's often recommended that the patient wear a wrist brace throughout the healing process to provide extra support, pain relief ...
The volar forearm splint is best for temporary immobilization of forearm, wrist and hand fractures, including Colles fracture. [ citation needed ] There are several established instability criteria: [ citation needed ] dorsal tilt >20°, comminuted fracture, abruption of the ulnar styloid process, intraarticular displacement >1mm, loss of ...
