We report the short-term results of 100 cementless total hip replacements in 52 severely dysplastic and 48 totally dislocated hips, with some new technical solutions to the problems involved. In cases with a very narrow iliac bone, the acetabular screw ring is seated below the true cotyloid area. In hips with tight flexor
110 patients with injuries to the ulnar nerve were assessed, on average, 12.7 (3-20) years after secondary repair. 89 were male and 21 female, with a mean age of 27.9 years. Most of the nerve lesions were sharp (63) or blunt (41) injuries. Division was total in 76 cases and most were at the forearm level. The average delay from the injury to the operation was 10.1 (1-48) months. Secondary repair was performed in 34 cases and fascicular grafting in 76 cases. The mean graft length was 5.4 (1-30) cm. Four factors of motor and sensory function were assessed and the quantitative evaluation was compared with the MRC classification. Useful results were obtained in only 51.8% and poor in 30.9%. The age of the patient, the width of contusion, the pre-operative delay, and the level of the injury influenced the results significantly.
33 patients with injuries to the radial nerve were reviewed, on average, 12.1 (5-20) years after secondary repair. 24 were male and nine female, with a mean age of 29.8 (7-54) years. Most of the nerve lesions were blunt (17) or sharp (14) injuries. Division was total in 24 cases and they were mostly injured at the upper arm level (21 cases). The average interval between injury and repair was 6.0 (1-19) months. The procedures used were fascicular grafting in 21 and direct suture in 12 cases. Motor and sensory recovery were evaluated quantitatively. Useful results were obtained in 65.0% and useless in 25.0%. Fascicular grafting restored a useful level of motor function in only 8/21 cases (38.1%). Pre-operative delay had a significant influence. Associated lesions proved to be the critical factor for restoration of radial nerve function.
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.
