367, p?=?0.002) and duration from injury to surgery (r?=?�C0.279, p?=?0.018) ( Table 1). None of the correlation coefficients between independent variables (age, gender, hand dominance, fracture location, joint involvement, associated soft-tissue injury, duration from injury to surgery and location of plate placement) was greater than 0.8, and therefore multicollinearity was not evident. With a backward stepwise procedure, the final multiple linear regression model, including fracture location, age and associated soft-tissue injury, resulted in formulae that could account for 46.3% of the variability in postoperative %TAM: fracture location (��?=??0.388, p?SB431542 associated soft-tissue injury (��?=?�C0.296, Tryptophan synthase p?=?0.002) ( Table 2). Although several risk factors affecting postoperative outcome have been proposed, there is still lack of information regarding what factors contribute to range of finger motion following treatment with plate and screws for metacarpal and phalangeal fractures.7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22?and?23 In the current study, multivariate linear regression analysis was used to determine independent predictors of the postoperative %TAM following open reduction and internal fixation with a titanium plate. We found three independent variables including fracture location, age and associated soft-tissue injury. The final regression model revealed that these three predisposing factors contributed 46.3% to total variance of the outcome variable. selleck chemical These results suggest that phalangeal fracture, elderly and associated soft-tissue injury were important risk factors to identify the postoperative range of finger motion. Fracture location was the first significant predictor. The result of phalangeal fractures as a significant risk factor was comparable with results of previous studies, which demonstrated that plate fixation of phalangeal fractures can be fraught with complications and unsatisfactory results.8, 9, 10, 13, 14, 16, 18, 20, 21?and?23 Pun et al.9 described that the plates were too large for the small phalangeal bones and the screw heads could be prominent and interfere with extensor tendon excursion. Bannasch et al.23 analysed postoperative complications of 365 patients with metacarpal or phalangeal fractures and described that the patients with fractures of the middle phalanx were increased risk of complications. This result may be due to the complexity of the anatomical structures of the proximal and middle phalanx of the hand. The extensor and flexor tendons are located very close to the bones at the phalangeal level, and there is almost no soft tissue interposed between the tendon and bone compared with the metacarpal level, leading to adhesion between the implant and the tendons.10 In the current series, the extensor tendons were observed to be a specific cause of adhesion when we performed tenolysis with removal of the plate.
