The results of 62 ankle arthrodeses, mostly performed for osteoarthritis, have been reviewed; of these, 39 were examined clinically and radiographically after an average follow-up period of seven years. Compression arthrodesis was associated with the highest incidence of complications, and an anterior sliding graft gave the most satisfactory results. Very few patients required modffication of their footwear; most could walk independently with a slight limp and were able to return to their pre-operative work. However, after operation, the ability to run and to participate in vigorous sporting activities was limited. Complications included wound infection, non-union, and some change in midtarsal mobility, but excellent pain relief was reported by all patients.
This paper describes the relationship between post-myelographic symptoms and the timing of a subsequent spinal operation. A prospective study was performed comparing the post-operative symptoms of patients who underwent discectomy within 48 hours of myelography (Group 1) with those of patients who underwent discectomy at least seven days after myelography (Group 2). After myelography there was no statistical difference in the incidence of nausea and headache in the two groups. However, after operation the incidence of headache and nausea was significantly greater in patients who underwent early discectomy. The incidence of urinary retention was significantly greater in Group 1 at 24 hours after operation but not at 48 and 72 hours. We conclude that the temptation to perform discectomy shortly after myelography should be resisted until at least one week has elapsed between the two procedures, except in emergency situations.
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.
