Patients with anterior shoulder instability treated with the traditional Latarjet technique had greater bony contact with the glenoid and greater bone width on each side of the screws, which allowed for a larger surface for healing, compared with the congruent arc modification of the Latarjet technique, according to results.

Matthew T. Provencher, MD, and colleagues analyzed CT scans of 24 active-duty military personnel (8.3% were women) with anterior shoulder instability without a previous coracoid transfer procedure. Investigators compared the surface area of the coracoid available for bony contact with the anterior glenoid and width of bone on each side of a 3.5-mm screw for the traditional Latarjet technique vs. the congruent arc modification of the Latarjet technique.

Results showed the traditional Latarjet technique had approximately 5.65 cm2 surface area available for bony contact to the anterior glenoid compared with approximately 3.64 cm2 with the congruent arc modification of the Latarjet technique. On each side of centrally placed 3.5-mm screws, researchers found the traditional Latarjet technique had an approximately width of 7.1 mm vs. an approximate width of 4.1 mm using the congruent arc modification. – by Casey Tingle
