Madelung in 1879 described a painful deformity of the wrist which occurs in adolescence with no history of previous injury or infection. The distal growth plate of the radius, which is the primary site of the abnormality, has premature fusion of the antero-medial quadrant. As growth proceeds the characteristic deformity is produced which is now associated with the name of Madelung. The articula...

The effectiveness of navigation systems in performing accurate orthopaedic surgery has been reported previously, but there have been no reports on the application of navigation in surgeries involving bone resection around the elbow joint. In this study, anatomical plasty or bone resection was performed to restore anatomical morphology in 10 cases of osteoarthritis of the elbow and deformity of ...

PTH and mechanical loading might act synergistically on bone formation. We tested the in vivo effect of the L-type voltage-sensitive calcium channel (VSCC) blocker, verapamil, on bone formation induced by human PTH-(1-34) (PTH) injection with or without mechanical loading. Adult rats were divided into eight groups: vehicle, verapamil, PTH, or verapamil plus PTH with or without mechanical loadin...

The accuracy of an empirically derived density-modulus equation for bone depends upon the loading conditions and anatomic site of bone specimens used for experimentation. A recent study used FE modeling to compare the ability of three density-modulus relationships to predict strain during bending in neutral forearm rotation in the distal ulna; however, due to the inhomogeneous nature of these F...

ON 15th May, 1952, a private soldier was vaulting over a "horse" in the gymnasium when he wrenched his left wrist, sustaining a forward dislocation of the head of the ulna and a fracture of the styloid process and adjacent meta-physis of the ulna. The mechanism of the injury appears to have been as follows: His hands were placed on the end of the "horse" in full pronation, and instead of pushin...

We reviewed 23 patients who had had 25 Darrach procedures for traumatic or post-traumatic disorders of the wrist at a mean follow-up of 75.5 months (36 to 121). The mean age at the time of operation was 61.1 years (34 to 82). All patients were reviewed in person. Assessment included a history, a questionnaire on patient satisfaction and a detailed physical examination. Standardised radiographs ...

Acupuncture can affect bone healing by stimulation of sensory nerves and releasing of local and systemic neuropeptides. The purpose of this experimental study was to evaluate the effects of electroacupuncture on ulna fracture healing in dogs. In this study, 12 healthy dogs were randomly divided in to four equal groups, where group 1 was kept as control group and evaluated for 45 days, group 2: ...
