Abstract

We evaluate the functional and radiological outcomes, the union rates and functional results in a group of patients with diaphyseal fracture of the humerus of the distal third with a minimally invasive technique whit posterior approach and anatomical plate. Between 2013 and 2017, 32 patients were operated, with an average age of 31years. Functional assessment was performed using the abbreviated DASH functional scale and pain was classified according to the VAS scale.

All the fractures healed successfully, except for two cases that presented in union delay. The radial nerve injury prior to the intervention was recovered progressively without requiring transfers. The functional results were satisfactory in the patients who completed more than one year of follow-up. The posterior approach of the minimally invasive surgery in the treatment of this particular fracture pattern seems to show a biological advantage by allowing complete union rates in all patients. The iatrogenic injury of the radial nerve does not seem to increase in relation to its isolation and protection in the proximal portion of the triceps Level of evidence: IV.
