Background:There are limited data available regarding outcomes following pectoralis
major tendon (PMT) reconstruction with allograft.Purpose:To evaluate the functional outcomes and complication profile following PMT
reconstruction with allograft in a military population.Study Design:Case series; Level of evidence, 4.Methods:All active duty military personnel who underwent PMT allograft reconstruction
between 2008 and 2013 were identified. Demographics, injury characteristics,
and surgical technique were recorded from the electronic medical record.
Self-reported pain scores and manual strength were evaluated pre- and
postoperatively, as recorded in physician electronic medical record notes,
in addition to the ability and degree to which each patient was able to
return to function. Standardized outcome measures included the Bak criteria;
visual analog scale for pain; Disabilities of the Arm, Shoulder and Hand
(DASH) score; American Shoulder and Elbow Surgeons (ASES) score; and 36-Item
Short Form Health Survey (SF-36). Complications, including rerupture and
reoperation, were additionally recorded.Results:Nine male patients (mean ± SD age, 35.7 ± 5.8 years) underwent allograft PMT
reconstruction. Mean improvement in self-reported pain score at a mean 53.5
months (range, 31.1-110.9 months) was 2.1 ± 1.3 points (P =
.08). Improvements in manual strength during forward flexion (0.5 ± 0.7;
P = .03), adduction (0.6 ± 0.6; P =
.01), and internal rotation (0.5 ± 0.7; P = .03) were
significant. Seven patients (78%) returned to full preinjury level of
occupational function, and 88% returned to performing the bench press,
although maximum weight decreased by a self-reported mean of 141.3 lb.
According to the Bak criteria, 5 (56%) patients had excellent outcomes, 2
(22%) had fair outcomes, and 2 (22%) had poor outcomes. Mean visual analog
scale for pain (1.9 ± 2.8), DASH (10.8 ± 17.4), ASES (88.1 ± 20.3), and
SF-36 scores (96.3% ± 6.9%) were obtained for the 8 patients available at
final follow-up. Complications included 2 cases (22%) of persistent shoulder
pain leading to military separation, 1 rerupture (11%), and 1 (11%) surgical
scar revision.Conclusion:While allograft reconstruction is a reliable option to decrease pain and
improve function in patients with tears not amenable to primary repair,
patients should be educated about the risk profile and fitness limitations
after surgery.
