Abstract |
Background |
In the event of a rupture of the distal tendon of the biceps brachii, most authors recommend early reinsertion to recover optimal elbow function. However, these ruptures are not always diagnosed or promptly referred to surgeons, thus creating a delay in treatment. Studies reporting functional results in cases of chronic repair (greater than 21 days) of the distal biceps brachii tendon show an increased rate of complications.
Hypothesis |
Primary repairs of chronic ruptures (treatment delayed for more than 21 days) and acute ruptures of the distal biceps give the same functional results and the same rate of complications.
Material and methods |
We conducted a retrospective study between January 2017 and December 2021 comparing chronic primary repair of the distal biceps at the elbow (experimental group, comprising 75 patients) and acute (control group, comprising 135 patients) by endobutton. We analyzed the time between trauma and surgery, and assessed short- and long-term functional recovery by measuring residual pain (VAS), a collection of the following functional scores: Mayo Elbow Performance Score (MEPS), Quick Disabilities of the Arm, Shoulder and Hand (Q-DASH) and Patient-Rated Elbow Evaluation (PREE), as well as a measure of strength (as a percentage of the healthy side). We evaluated the rate of complications and radiographically analyzed the rate of heterotopic ossification.
Results |
The mean time between trauma and surgery was 73±66 days (experimental group) versus 11.2±5 days (control group). In the short-term (4.79±2.09 months), there was no significant difference in the MEPS, Q-DASH and PREE functional scores between the two groups (p=0.354, p=0.412 and p=0.958, respectively). In the long-term (28.9±17.9 months), the functional evolution remained similar. The recovery of strength in flexion and supination was 89.19±13.43% and 77.48±16.68%, respectively, and similar in the two cohorts (p=0.476 and p=0.395). There was no difference in the rate of complications; however, the rate of heterotopic ossification was higher in the control group (p=0.006).
Discussion |
The functional results and the recovery of strength did not change according to the time until surgery. Although the overall complication rate was similar, repairs of the biceps in less than 21 days led to more heterotopic ossification.
Level of evidence |
III; retrospective case-control study.
