Background: Flexor tendon repair carries a significant risk for complications, which often leads to revision surgery. The purpose of this study was to assess the effect of different factors on the risk for major complications patients undergoing a primary end-toend flexor tendon repair and early passive mobilization regimen (Kleinert protocol). Methods: Between January 2000 and September 2009, a total of 312 patients underwent a flexor tendon repair at out institution. We excluded patients whose injury was self-inflicted or secondary to a rheumatic disease or a fall leaving 187 patients with 325 injured tendons for the study. Results: 152 (81.7%) patients were male and 34 (18.3%) females. Mean age of the patients was 32.7 years (SD 14.4, range 11 to 73). The fifth ray was most commonly affected. The majority of the injuries were located in zone II. Median delay to surgery was 3 days. Complications were observed in 34 patients (18.2%). Univariable analysis showed that patient age, mechanism of injury, injured ray, delay to surgery between three and seven days, and greater suture thickness were associated with increased risk of complications. In the subsequent multivariable analysis, only the mechanism of injury and delay to surgery remained as significant risk factors for major complications. Conclusions: We conclude that complications after flexor tendon repair may be reduced by appropriate timing of the surgery. Delay to surgery lasting between three and seven days seems to be associated with increased risk for major complications.
