Study finds, Olecranon Osteotomy With the Posterior Approach
A Study was conducted to determine if inclusion of an olecranon osteotomy to the posterior paratricipital approach for operative fixation of distal humerus fractures significantly affects surgical complication rates (OTA/AO 13).

304 patients underwent open reduction internal fixation of a distal humerus fracture between 2007 and 2017. Of those, 134 met inclusion criteria for the study (n = 64 with olecranon osteotomy; n = 70 without olecranon osteotomy).

Open reduction internal fixation of distal humerus fractures was performed using a posterior paratricipital approach with or without olecranon osteotomy.

--31 who underwent the paratricipital approach without olecranon osteotomy, and 15 patients who underwent olecranon osteotomy reported postoperative UN with no significant difference between approaches.

--There was no significant difference in rates of SSI or fracture site nonunion when comparing the approaches.

--Subjects with Charlson comorbidity index more than 2 were more likely to not undergo an olecranon osteotomy, whereas subjects with more complex fractures by OTA/AO classification were more likely to have an olecranon osteotomy approach.

Addition of an olecranon osteotomy with the paratricipital approach for fixation of distal humerus fractures does not result in higher rates of UN, fracture site nonunion, or SSI.
