Background:
Repair of distal biceps tendon ruptures include one- or two-inci-
sion techniques. Among various fixation techniques, biomechanical studies have
shown that endobuttons have the highest load-to-failure strengths.
Purpose / Aim of Study:
We hypothesize that the use of a single incision and
endobutton would provide reliable fixation with good functional result and few
complications. Accordingly, the aim of the study was to report our results using
this technique.
Materials and Methods:
Patients operated during 01.01.10 –01.11.15 were
identified by ICD-10 & NOMESCO codes. Patient records were studied and
questionnaires incl. ROM and DASH score were sent by mail. Non-responders
were reminded after 3 weeks by phone.
Findings / Results:
30 patients were identified; 1 were lost to follow-up. 5 did
not respond despite reminder. 24 patients remained (23 males) with a mean
age of 49 years (38-67). Median delay to surgery was 7 days (1-58) and me-
dian follow-up time was 25 months (6-58). The median DASH score was 22.5
(0-84.17). Compared to the uninjured side, the mean loss of ROM was: exten-
sion 15° (0-50°), flexion 6° (0-40°), supination 18° (0-55°) and pronation
11° (0-50°). 1 re-rupture occurred, but was successfully reoperated using
the same technique. No patient had deep infection. 6 patients had neurological
symptoms at the latest clinical control: 3 non- specific, 1 had symptoms specifi-
cally related to the superficial branch of the radial nerve and 2 had symptoms
related to the lateral antebrachial cutaneous nerve. No patients had motor palsy.
Conclusions:
Surgical repair of distal biceps tendon rupture with one-incision
technique and endobutton fixation had a low rate of mechanical failure. Most
patients had only slightly reduced ROM, but there was a relatively high rate of
neurological complications. The average DASH score was higher than previously
reported.
