Treatment of the ulna non-unions using dynamic compression plate fixation, iliac bone grafting and autologous platelet concentrate

Clinical study of a series of ten patients treated between 2004 and 2009 for non-unions of the ulna. The patients have been treated with osteosynthesis using a dynamic compression plate and biological enhancement of the consolidation using bone graft and autologous platelet injection. The follow-up consisted of clinical and radiographic assessment. Functional scores used were the Visual Analogue Scale (VAS) for pain and the Disability Assessment for the Shoulder and Hand (DASH) questionnaire. The mean time of follow-up was 21 months. Considering both clinical and radiological criteria, bony union was achieved in 9/10 cases on average time of 4 months. According to the system of Anderson, 5 patients provided an excellent result, 2 a satisfactory result, 2 an unsatisfactory result and 1 treatment resulted in failure. At follow-up, the mean VAS score for pain in the upper limb was 1 (range, 0–4) at rest and 2 (range, 0–7) during activities. The physical function and symptoms of the upper limb, evaluated with the DASH questionnaire, scored 17 points. In conclusion, at a mean 21 months follow-up, there was high success regarding both forearm alignment, clinical and functional results. The use of three combined methods provides high success regarding both radiological and clinical results, even if we have no information on the prevalent efficacy of one particular method.
