Abstract
Aim: To investigate the effectiveness of the non-union scoring system (NUSS) in predicting the result and inguiding the treatment by comparing the treatment methods applied to non-union patients we treat in our clinicwith the treatment methods suggested by the NUSS. Methods: The study included 116 patients, who were diagnosed with long bone (femur, tibia and humerus)non-union and treated in our clinic. Of the 116 patients with non-union, 48 had femur (41.38 %), 39 had tibia(33.62%) and 29 had humerus (25%) non-union. The patient scores were calculated according to the NUSScriteria. The patients were divided into four groups according to their total scores. There were 34 patients inthe first group (0-25 points), 49 patients in the second group (26-50 points), 30 patients in the third group (51- 75 points) and three patients in the fourth group (76-100 points).Results: Union that was achieved in 79 (68.10%) of all patients was detected in 97.05% of the patients in thefirst group, 83.67% in the second group, and 16.66 % in the third group. Amputation, arthroplasty andarthrodesis were applied to three patients in the fourth group. While union rate was 100 % in the femur andtibia in the first group, it was 90% in the humerus. The union rates were 85.71% in the humerus, 75% in thefemur and 100% in the tibia in the second group. They were 20 % in the humerus, 15.38% in the femur and16.66% in the tibia in the third group. The number of patients treated with the treatment proposed by the NUSS:100% in the group 1, 83.67% in the group 2, 20% in the group 3 and 100% in the group 4. The risk of non union in those who were not treated according to the NUSS recommendations was 28 times higher than thatof others. Conclusions: The results of our study suggest that more frequent use of the NUSS procedure in non-uniontreatment planning may increase treatment success. In addition, NUSS can provide information about thetreatment process of non-unions.
