Malunion of fractures of the forearm in children can lead to permanent disability. The capacity of the radius and ulna to remodel spontaneously after malunion has been assessed in this study. Forty-nine children who had malunited fractures of the forearm were examined when the remodelling process was complete. It was noted that fractures of the distal third of the radius and ulna led to fewer problems than those of the diaphysis. It was concluded that malunion of the distal third of the radius and the ulna will remodel satisfactorily providing the child is less than 14 years of age. Gross malunion of the midshaft of the radius and ulna will spontaneously correct in an infant but little useful correction of deformity can be anticipated in diaphysial fractures when the child is aged eight years or more.
The functional and psychological outcome of 43 patients with polyarticular juvenile arthritis was assessed in order to evaluate the impact of disease on their quality of life. Mean disease duration was 19.7 yr (range 10-39 yr), mean age 26.7 yr (range 18-54 yr) with sex ratio 1:3 (male:female). Severe disability was present in 8% of systemic onset, 34% of RF negative (Rh-P), 38% of RF positive (Rh+P) and 86% of extended pauci-articular (ExP) juvenile arthritics-this last high percentage was due to ocular impairment. The Rh+P had more hip (100% of the group) and knee prostheses (31%) compared with Rh-P (77 and 11% respectively). The Rh+P and ExP groups were the most disabled with the highest proportions of patients with currently active disease (85 and 71% respectively). Psychological testing showed that 21% of the patients were clinically depressed and the rate increased (P = 0.06) with the degree of disability. The proportion of patients demonstrating an anxious preoccupation with their disease increased (P = 0.002) with the degree of disability. Despite this, 66% of patients were employed and 38% felt that their arthritis had no effect on their ability to form relationships.
The range of rotation of the talus in the horizontal plane was studied in the cadaveric ankle under conditions which simulated normal load-bearing. In the unloaded state there was 25 degrees of rotation, approximately half of which resulted from movement of the inferior tibiofibular joint. Rotation was load-dependent in both the intact ankle and in the ankle rendered unstable by division of the ligaments. Experimental division of the ligaments increased the range of rotation. The malleoli were contact areas during flexion and extension but excision of their articular surfaces caused only a moderate increase in rotation. The factors which limit talar rotation in intact and injured ankles are discussed.
An accessory extensor pollicis longus muscle within the third extensor compartment resulted in dorsal wrist pain that resolved following excision of the accessory muscle.
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.
