ABSTRACT

Objective: We undertook this study to identify the prognostic factors of nonunion in traumatic fractures treated and stabilized by the method of Colchero.
Methods: Included in the study were 140 patients with bone infection, 31 with traumatic fractures treated and stabilized with the method of Colchero, of which 26 healed and 5 evolved to nonunion. Factors analyzed were age; sex; occupation; smoking; alcoholism; presence of degenerative diseases; cause, type and pattern of the fracture; bone affected; type of implant; hemoglobin; neutrophils; lymphocytes; proteins; albumin; and erythrocyte sedimentation rate.
Results: Significant differences were found in complex or comminuted fractures with a risk of 11.5 times higher of resulting in nonunion (p = 0.038). Average of neutrophils in nonunion was 1.8 ± 0.69 vs. 5.5 ± 1.7 in consolidation (p = 0.008); average of albumin was 4.2 ± 0.31 in nonunion vs. 3.8 ± 0.36 in nonunion consolidation (p = 0.022).
Conclusions: We should consider comminuted fracture as a risk for nonunion, in relation to nutritional and immunological factors. Patients who consolidated presented neutrophils in the normal range as a response to the bacterial infection with a decrease in albumin levels because of the bone repair process. In nonunion there was neutropenia with normal albumin levels, which most likely suggests an inadequate response to the infection. Albumin remains within normal ranges because there is no bone repair process.
