Background Tendon rupture has been recognized as a complication of distal radius fracture (DRF); however, the clinical outcome of reconstructive surgery for this injury remains unclear. We examined prognostic factors for the outcomes of reconstructive surgery in patients with a tendon rupture after DRF. Methods This study was a retrospective review of a case series. Seventy-five consecutive patients were treated at our institution for tendon rupture after DRF. The cohort included 14 males and 61 females with a mean age of 67.7 years at the time of tendon reconstruction. Sixty-four and eighteen tendon ruptures occurred after non-operative management for DRF and palmar locking plate fixation, respectively. Seven ruptured tendons received a free tendon graft from the palmaris longus tendon, and the others underwent tendon transfers. All patients were managed postoperatively by our hand therapy unit according to a controlled active mobilization regime. Results The mean follow-up period was 28 weeks (range: 12–80 weeks). Patients with extensor tendon ruptures were significantly younger than those with flexor tendon ruptures regardless of the initial DRF treatment. The mean percentage active range of motion of the injured digits relative to normal active motion (%AROM) at the final follow-up was 70% (range: 30–101%) in all patients. The %AROM after flexor tendon reconstruction for patients after non-operative management was significantly inferior to that of other patients. Multiple regression analysis revealed that aging and non-operative management of DRF are independent risk factors for poor %AROM. Conclusions This study confirmed that advanced age and non-operative management of DRF were prognostic factors for digital joint motion following surgical reconstruction for tendon rupture. Our results suggest that it may be difficult to achieve good clinical outcomes in elderly patients with tendon ruptures (particularly flexor tendon ruptures) following non-operative management of DRF.
