Subacromial decompression increased superior compliance by 32%, from 3.1 ± 1.5 mm in the native specimen to 4.1 ± 1.8 mm (P =.03).
Weiner et al. studied plain radiographs showing superior migration of the humeral head (increased superior glenohumeral translation) in static rotator cuff-deficient shoulders, thus supporting the fact of superior pull by the deltoid on the humerus (Weiner and Macnab [1970]).
Moreover, a distal position of the mandible, confirming the more distal position of glenoid fossa, in BR group was suggested by a significantly lower articular angle (S^Ar^Go), increased superior gonial angle (Ar^Go^N), and increased S-Ar distance when compared to GR group.
CAL release with the Latarjet procedure leads to increased superior humeral translation.
Raising intestinal luminal glucose above 30 mM results in increased superior mesenteric arterial flow from around 1000 2500 ml min -1.
These studies have demonstrated increased superior translation with varying forces applied to the shoulder following CAL resection [ 1, 2, 4, 6, 7].
In addition, the current observation of increased superior temporal gyrus activation as a linear function of load in FH participants is very similar to that reported by Walsh et al. (11) in depressed patients.
There are also concerns about the lack of increased superior mesenteric artery blood flow in response to a feeding, following a blood transfusion, 17 suggesting that feeds should be held after a transfusion.
They found increased superior translation of the humeral head on the glenoid in both tear groups compared to the no-tear group, but there were no statistically significant differences between the symptomatic tear group and the asymptomatic tear group.
The classic and congruent-arc Latarjet procedures, which disrupt the CAL, increase superior humeral head translation and possibly anterior glenohumeral instability.
