| Abstract |
To evaluate the significance of biceps tendon (BT) displacement and peri-bicipital hematoma on MRI in subjects with pectoralis major (PM) tears. We hypothesized that these features might be associated with tear severity at surgery. We retrospectively identified MRI cases with PM injury and reviewed clinical, imaging, and surgical records. MR images were reviewed independently by two musculoskeletal radiologists to determine anterior displacement of BT (BT-disp, in mm) and the presence of triangular-shaped peri-bicipital hematoma. Data were compared with an age- and sex-matched control group and correlated with surgical reports grouped by tear severity. We identified 46 subjects with PM injury (43 men, 3 women; mean age 34 ± 9 years), 26 of whom underwent surgical reconstruction, and 20 matched controls (P > 0.2). BT-disp was significantly higher in PM injury vs controls (P = 0.003), and in tendon vs myotendinous (MT) junction PM tears (P < 0.0001); however, MT junction tears vs controls were similar (P = 0.98). Higher BT-disp and presence of peri-bicipital hematoma correlated significantly with surgical reports describing full-thickness complete tears. BT-disp > 4.5 mm had 86% sensitivity and 75% specificity to detect the most severe tears on surgical reports, whereas the presence of peri-bicipital hematoma was the strongest predictor among both parameters. Anterior BT displacement and peri-bicipital hematoma are helpful indicators of full-thickness complete tears at the humeral insertion. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 17 July 2018.
All research outputs
#18,643,992
of 23,096,849 outputs
Outputs from Skeletal Radiology
#1,170
of 1,481 outputs
Outputs of similar age
#332,269
of 442,911 outputs
Outputs of similar age from Skeletal Radiology
#51
of 66 outputs
Altmetric has tracked 23,096,849 research outputs across all sources so far. This one is in the 11th percentile – i.e., 11% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,481 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.3. This one is in the 9th percentile – i.e., 9% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 442,911 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 14th percentile – i.e., 14% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 66 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
