Triangle Tilt Surgery As Salvage Procedure
for Failed Shoulder Surgery in Obstetric Brachial Plexus Injury
Numerous children with obstetric brachial plexus injury come to our practice for evaluation after having had surgery with other specialists at other hospitals. Many of them were candidates for the Triangle Tilt Surgery (based on Shear Deformity, Mallet Scale and PHHA glenoid version).
The post operative evaluations reported the following changes:
Mallet Scale: increased from 11.88 points to 15.88 points
PHHA: improvement (a) from 14% to 25% of humeral head anterior to the glenoid and (b) -32 degrees to -25 degrees improvement of glenoid version
SHEAR Deformity: a marked decrease in scapular hypoplasia, elevation and rotation
Our study of 48 OBPI patients proved that even though they had previous surgeries, the Triangle Tilt still brought about greatly improved shoulder function and anatomy.
