Radial deviation of the wrist is caused by lack of support to the carpus, radial deviation may be reinforced if forearm muscles are functioning poorly or have abnormal insertions. [3] Although radial longitudinal deficiency is often bilateral, the extent of involvement is most often asymmetric. [1]
Half of nonosteoporotic patients will develop post-traumatic arthritis, specifically limited radial deviation and wrist flexion. This arthritis can worsen over time. [6] Displaced fractures of the ulnar styloid base associated with a distal radius fracture result in instability of the DRUJ and resulting loss of forearm rotation. [citation needed]
The extensor carpi radialis longus is a wrist extensor that is innervated by the radial nerve, [2] [3] from spinal roots C6 and C7. [4] All other major extensor muscles in the superficial layer of the posterior compartment (the extensor digitorum , extensor carpi radialis brevis , extensor carpi ulnaris , and extensor digiti minimi ) are ...

The extrinsic muscle groups are the long flexors and extensors. They are called extrinsic because the muscle belly is located on the forearm. The intrinsic group are the smaller muscles located within the hand itself. The muscles of the hand are innervated by the radial, median, and ulnar nerves from the brachial plexus. [1]
Adults with Madelung’s deformity may suffer from ulnar-sided wrist pain. Madelung's Deformity is usually treated by treating the distal radial deformity. However, if patients have a positive ulnar variance and focal wrist pathology, it’s possible to treat with an isolated ulnar-shortening osteotomy.
It is an extensor, and an abductor of the hand at the wrist joint. That is, it serves to manipulate the wrist so that the fingers moves away from the palm. The muscle, like all extensors of the forearm, can be strengthened by exercise that resist its extension; Reverse wrist curls with dumbbells can be performed.
