Hand and Wrist Treatment
- Each human hand contains little-sized bones, called the phalanges, metacarpals and the carpals; whereas, the wrist encompasses the ending of the larger bones of the ulnar and radius from the lower arm. A total of 27 bones comprise the hand and wrist.
- Muscles of the hand is divided into just three groups depending upon the location or depth. Thenar muscles control the thumb; while, hypothenar muscles regulate the little finger. Three middle fingers fall under control of three other sets of muscles. These muscles control fine motor skills used for such skills as grasping objects, writing or brushing teeth.
Injuries and Traumas of the hand:
Tendon injuries (cut, torn, frayed or pulled apart) universally occur on the fingers, because the flexor tendon lies on the palmar side of the finger or the side that grasps objects. These injuries arise from a knife, sharp tool, broken glass or workers using cutting tools. Puncture wounds or lacerations over the tendon can result in partial or complete cuts (transection). Tendon lacerations require surgical intervention to reconnect the open area on the tendon. Microsurgery may be necessary if blood vessels or nerve injury occurs, concomitantly.
Arthritis and Deformities:
The multiple small joints work together to generate movement to carry out such activities as threading a needle or tying a bow. Overtime, the arthritis worsens, pain develops, the joints lose their natural shape and activities with the hands become more difficult. In osteoarthritis, the most common form of arthritis, the cartilage in the small joints wears away; whereas, in rheumatoid arthritis, the fluid in the joint lining swells leading to pain and stiffness. X-rays, MRIs or bone scans help to diagnosis arthritis.
