Background Ulnar-sided wrist pain is a common problem in the upper extremity. It affects a broad patient population and can be difficult to treat. Ulnar impaction syndrome (UIS) is major cause of ulnar-sided wrist pain and a number of different operations have been used to correct it, including ulnar shortening osteotomy (USO). Objective To retrospectively review functional outcomes and complication rates of USO for UIS at the Hand and Upper Limb Centre (London, Ontario) over a two-year period. Methods Twenty-eight patients who underwent USO between 2007 and 2009 participated in the present study. Ulnar variance pre- and post-surgery was assessed using standard radiographic examination. Patient-rated outcomes were measured using a visual analogue scale (VAS) for pain and the Disabilities of the Arm, Shoulder and Hand (DASH) survey for functional outcomes. Objective grip strength and range of motion were compared with the contralateral extremity. Results On average, USO achieved a 3.11 mm reduction in ulnar variance. Nonunion occurred in five patients and required a secondary bone grafting procedure. All USO eventually healed. Overall, pain improved by 47.2% and the mean DASH score after surgery was 37.21. Flexion, extension and supination range of motion decreased by 10° compared with the unaffected side. Eleven patients (39%) elected to undergo a second surgery for hardware removal. Patients receiving compensation from the Workplace Safety and Insurance Board experienced significantly higher residual pain (VSA 5.24 versus 1.97) and disability levels (DASH 60.23 versus 25.70). Smokers also experienced worse outcomes in terms of pain (VSA 4.43 versus 2.36) and disability (DASH 51.06 versus 29.67). In this cohort, smoking was not associated with a higher rate of nonunion. Conclusion USO is effective in reducing pain in UIS and improves disability, at the price of a small decrease in range of motion. Smokers and people receiving compensation from the Workplace Safety and Insurance Board, however, have significantly worse subjective outcomes (VAS and DASH), but similar objective outcomes (range of motion).

A comparison of revisional and primary bariatric surgeryBackground: Revisional surgery is an important component of addressing weight regain and complications following primary bariatric surgery. Owing to provincial need and the complexity of this patient population, a specialized multidisciplinary revision clinic was developed. We sought to characterize patients who undergo revision surgery and compare their outcomes with primary bariatric surgery clinic data. Methods:We completed a retrospective chart review of bariatric revision clinic patients compared with primary bariatric surgery patients from December 2009 to June 2014. Results:We reviewed the charts of 2769 primary bariatric clinic patients, 886 of whom had bariatric surgery, and 534 revision bariatric clinic patients, 83 of whom had revision surgery. Fewer revision clinic patients underwent surgery than primary clinic patients (22% v. 32%). The mean preoperative body mass index (BMI) was 44.7 ± 9.5 in revision patients compared with 45.7 ± 7.6 in primary bariatric surgery patients. Most revision patients had a prior vertical banded gastroplasty (VBG; 48%) or a laparoscopic adjustable gastric band (LAGB; 24%). Bands were removed in 36% of all LAGB patients presenting to clinic. Of the 134 procedures performed in the revision clinic, 83 were bariatric weight loss surgeries, and 51 were band removals. Revision clinic patients experienced a significant decrease in BMI (from 44.7 ± 9.5 to 33.8 ± 7.5, p < 0.001); their BMI at 12-month follow-up was similar to that of primary clinic patients (34.5 ± 7.0, p = 0.7). Complications were significantly more frequent in revision patients than primary patients (41% v. 15%, p < 0.001). Conclusion:A bariatric revision clinic manages a wide variety of complex patients distinct from those seen in a primary clinic. Operative candidates at the revision clinic are chosen based on favourable medical, anatomic and psychosocial factors, keeping in mind the resource constraints of a public health care system.

Compte tenu des besoins provinciaux et de la complexité de cette population de patients, une clinique de révision multidisciplinaire spécialisée a été créée. Nous avons voulu caractériser les patients qui subissent une chirurgie de révision et comparer leurs résultats aux données de la clinique de chirurgie bariatrique primaire.Méthodes : Nous avons procédé à un examen rétrospectif des dossiers des patients de la clinique de révision bariatrique par rapport aux patients ayant subi une chirurgie bariatrique primaire entre décembre 2009 et juin 2014.Résultats : Nous avons examiné les dossiers de 2769 patients de la clinique bariatrique primaire, dont 886 avaient subi une chirurgie bariatrique, et 534 patients de la clinique de révision, dont 83 avaient subi une chirurgie de révision.
