The anatomy of the first metatarso-phalangealjoint and of dorsal dislocation of the phalanx are described. As with similar lesions in the hand, closed reduction is impossible because of interposition of the volar plate. Open reduction is essential and should be performed as soon as possible after the injury.
Four cases of osteoid osteoma of the terminal phalanx--a very rare location--are presented. The clinical picture of cell cases is essentially the same, gradual swelling of the terminal phalanx with enlargement of the nail and pain, particularly at night and relievable by aspirin. The treatment was operative and of double value. 1. The osteoid osteoma is removed; 2. Cosmetic result is obtained by reduction of the size of the terminal phalanx.
1. Three patients with enchondromata of the metacarpal bones are described. 2. The nature of the enchondromata in all three patients was confirmed by histological examination. 3. Treatment was by radical excision and bridging of the gap by a cortical bone graft. 4. There has been no impairment of function in the hands. No patient complained of pain after the operation. 5. Radiographs taken one year after operation in two patients showed that the flat bone grafts had become cylindrical and that medullary canals had appeared.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
