We reviewed 63 trapeziometacarpal arthrodeses (57 patients) performed in our unit between April 2007 and May 2013 for osteoarthritis. K-wires, plates, headless compression screws and memory staples were used for fixation. The average age of patients was 50 (range 20-78) years and there were 36 men and 21 women with a mean follow-up of 36 (range 6-62) months. K-wires were used in 31 cases, staples in 12, plates in five, and screws in 15 joints. The overall non-union rate was 11%, however, when using K-wires for fixation, it was 20%. Union was achieved in all cases when staples or screws were used for fixation. Disabilities of the Arm, Shoulder and Hand scores were higher in cases where non-union occurred compared with those that united (66.7 vs. 21.9). Trapeziometacarpal arthrodesis for osteoarthritis gives good clinical outcome with lower (DASH) scores when union occurs. K-wire fixation led to a 20% non-union rate, and as a result, the senior author no longer uses this method of fixation.
Documentation of complications for THR and TKR patients was often incomplete and variable. The use of structured, procedure-specific consent forms is recommended.
This simple test may be highly beneficial preoperatively in identifying those patients likely to require longer inpatient stays and therefore those who would benefit from early nutritional intervention and focussed physiotherapy. It may also facilitate predictors of length of stay postoperatively. We believe this may effect significant cost reductions in the NHS.
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.
