Study among the first to focus on single-incision distal biceps tendon repair complications
BALTIMORE — Researchers found high complication rates associated with distal biceps tendon tears repaired with a single-incision technique, according to study results presented at the American Orthopaedic Society for Sports Medicine Annual Meeting 2012, here.
“Our overall complication rate was 58% with most common complication being transient sensory nerve dysfunction,” presenter Leslie Bisson, MD,
said. “These tend to resolve in 6 to 9 months in all the patients we
could verify and there is no association of complications with
tourniquet use or hardware. Workers’ compensation, although it had a
higher percentage of complications, was not statistically significant.
We did find fewer complications when the surgery was performed within
the first 2 weeks of injury.”
Bisson and colleagues studied 67 men who consecutively underwent
distal biceps repairs using a single-incision anterior approach between
2003 and 2010. The average follow-up was 5 months and average patient
age was 46 years. Twenty-nine patients had surgery within 2 weeks of
injury, 22 patients underwent repair within 2 weeks to 6 weeks and 16
patients had surgery more than 6 weeks post- injury.
The investigators used the Chi squared test to compare complications
by time to surgery, surgeon, hardware used, tourniquet use, and workers’
compensation cases.
They calculated a 58% complication rate, with transient nerve
dysfunction, infection, loss of motion, rerupture or hardware problems
among the complications noted. Among the seven workers’ compensation
patients, there was an 86% complication rate, but this was not
significant, Bisson said. The patients who underwent surgery within 2
weeks of injury showed lower complication rates than patients who
underwent repair 2 weeks after injury. The tourniquet time, hardware
type and longitudinal transverse incision were not significant factors
of complications.
“Outcome studies of single-incision repairs have had complications
ranging from 8% to 44% with the majority of these being sensory and
nerve dysfunction,” Bisson said. “But there has been no study that has
specifically focused on complications.”
