Background: Diaphyseal humeral fractures correspond to 3-5% of all fractures. The proportion of these fractures in which the distal third of the diaphysis is involved is variable with estimated incidences between 10-48%. The aim of the study is to evaluate the functional results and rate of fracture consolidation for a group of patients with distal third diaphyseal humeral fractures managed using a minimally invasive technique through a posterior approach.
Materials and methods: Twenty-two patients (mean age of 36 years) were evaluated between 2013 and 2016. Functional assessment was performed using the DASH abbreviated functional scale. Shoulder and elbow mobility range of motion were measured with goniometry, and pain was measured following the VAS scale.
Results: All fractures consolidated successfully, with two cases exhibiting delay in consolidation. Radial nerve injury prior to the intervention was progressively recovered without the need for supplementary tendons transfers. Functional results were satisfactory for ten patients that completed more than one year of follow-up.
Discussion: Minimally invasive technique with posterior approach in the treatment of this particular pattern of humeral fractures seems to show a biological advantage in allowing complete consolidation in all patients. Iatrogenic radial nerve injury does not appear to increase in relation to its isolation and protection in the proximal portion of the triceps.
Evidence level: IV.
