Percutaneous Scaphoid Screw Fixation

Abstract

Wrist 125Shand dominance, smoking, type of osteotomy (horizontal or oblique), and length of follow-up; and whether or not a trauma was involved. Methods: Between 2006 and 2014, 37 out of 46 patients who were operated on in our hospital were available for evaluation with a mean follow-up of 54 months (range, 7-69). Mean age at the time of surgery was 39 years (range, 15-69), 24 were women, in 19 the dominant hand was involved, 15 were smokers, and in 28 a horizontal and in 9 an oblique osteotomy was performed. In 18 a trauma was involved, and in 14 there was an associated fracture of the radius or ulna. In all patients, Disability of Arm Shoulder and Hand (DASH) questionnaire, patient rated wrist hand evaluation (PRWE), visual analogue scale (VAS) for pain, satisfaction, and complications could be assessed, and in 25 grip strength and range of motion were determined. Statistical analyses (Mann-Whitney U test, independent samples t test) were performed to find out which factors had an influence on the outcome. Multiple regression analysis was done to assess influences on the DASH score. Results: Mean DASH was 22 (range, 0-75) and mean PRWE score 33 (range, 0-90). Mean VAS for pain was 2.6 (range, 0-7.8). Thirty patients were satisfied and 7 would not undergo the same operation again. In 17 the plate and screws had to be removed. In 3 cases with a horizontal osteotomy, a second operation had to be performed for nonunion. Two of them were smokers. Mean grip strength was 84%, mean wrist flexion 84%, extension 75%, pronation 85%, and supination 86% of the contralateral side. PRWE and DASH scores were significantly better in smokers. PRWE was significantly worse in posttraumatic ulnocarpal impaction syndrome. Multiple regression analysis showed a significantly better DASH score in smokers, in patients operated on the nondominant side and with a longer follow-up. Discussion and Conclusion: Ulnar shortening may not be able to solve ulnar wrist pain in all patients as one fifth was not satisfied. Complications should not be underestimated. Reoperations were needed in half of patients. Outcomes were better in idiopathic ulnocarpal impaction. In posttraumatic cases, ligamentous lesions may also play a role in causing ulnar wrist pain. Results were better when the follow-up was longer which may indicate that recovery after ulnar shortening may take long time or that patients may have adapted their activities. In contrast to other studies, outcome scores in the present study were better in smokers, but 2 of the 3 patients with nonunion were smokers. Objective/Hypothesis: Scoring systems are widely used in medicine and surgery. During the last decade, the reduced version of the Disabilities of the Arm, Shoulder and Hand Score (QuickDASH) has established itself as the main Patient Reported Outcome Measures (PROMs) questionnaire used by hand surgeons. Another measurement tool can be used when the condition affects more precisely the wrist: the Patient-Rated Wrist Evaluation (PRWE). The aim of this study is to find out how corr...
