Performance and Return to Sport After Open Reduction and Internal Fixation of the Olecranon in Professional Baseball Players

Abstract

Background:

The results of open reduction and internal fixation (ORIF) of stress reactions and fractures of the olecranon among professional baseball players with regard to return to sport (RTS) are unknown.

Purpose/Hypothesis:

To determine the RTS rate and performance of professional baseball players after ORIF of acute, displaced olecranon fractures and olecranon stress fractures and to compare the RTS rate and performance with that of matched controls. The authors hypothesized that there is a high rate of RTS among professional baseball players after ORIF of acute, displaced olecranon fractures and olecranon stress fractures with no significant difference in rate of RTS or performance between cases and controls.

Study Design:

Cohort study; Level of evidence, 3.

Methods:

All professional baseball players who underwent ORIF of the olecranon between 2010 and 2016 were included. Demographic and performance data (before and after surgery) for each player were recorded. Performance metrics were then compared between cases and a group of matched controls.

Results:

Overall, 52 professional baseball players (mean ± SD age, 22.6 ± 3.6 years) underwent ORIF of an olecranon fracture. The majority of players sustained a primary olecranon stress fracture (73%) that was fixed with 1 screw (60%), with an overall RTS rate of 67.5%. No difference in RTS rate existed between matched controls and the cases. No significant difference existed between the primary pre- and postoperative performance metrics (ie, change in performance) for pitchers who underwent ORIF of an acute, displaced olecranon fracture or ORIF of a primary olecranon stress fracture. No significant difference existed between pitchers who underwent ORIF of a primary olecranon stress fracture and matched controls in any of the primary performance metrics. Three cases and 2 controls underwent ulnar collateral ligament reconstruction later in their careers after olecranon ORIF.

Conclusion:

Professional baseball players who undergo ORIF of an olecranon fracture (acute, displaced, or stress) have an RTS rate of 67.5% (57.6% to the same or higher level), which is no different from natural attrition among matched controls. No decline in performance metrics was seen among players who were able to RTS when compared with their preoperative performance or the performance of matched controls.
