A long time OCAD observer infrequent contributor here!
Unusual shoulder case on the reporting list today. Minimal history, just:
shoulder pain following injury ? SLAP tear.
There appears to be diffuse subacute denervation change involving teres
major.
Subscapularis is spared.
Patient appears to be an ex throwing athlete, with posterior inferior
glenoid bone spur at the labrocapsular attachment and posterior labral
tear. In New Zealand we see this fairly infrequently as seems to be less
common in our cricketers than in baseballers, who are pretty rare down here!
Questions:
1. Has anyone seen a similar constellation of findings or isolated
teres major denervation?
2. Are the two related- can a thrower somehow get a subscapular neuropraxia?
3. Why is subscapularis spared? Is this simply variant anatomy with
subscapularis receiving alternative supply.
Phil I noticed you had posted a similar case Lower Subscapular Muscle
Denervation (globalradiologycme.com)
<www.globalradiologycme.com/single-post/2016/11/04/lower-subscapular-muscle-denervation>;
in this case subscapularis was involved.
Thanks all
