“…Prior studies have shown that screws in the Latarjet procedure are bordered by about 4 mm of bone on each side. 42 In contrast, Tokish et al 21 described the placement of only one screw for fixation when using the distal clavicle for glenoid augmentation, thus potentially exposing the graft to rotational instability. If the distal clavicle graft is placed with its cut medial edge flush with the glenoid, so that its superior surface augments the glenoid curvature, the average length (22.3 mm) and height (12.5 mm) make dimensions favorable for two screw fixation.…”

Introduction The aim of this study was to anatomically compare distal clavicle and coracoid autografts and their potential to augment anterior-inferior glenoid bone loss. Methods Ten millimeters of distal clavicle and 20 mm of coracoid were harvested bilaterally from 32 cadavers. Length, weight, and height were measured and surface area and density were calculated. For each graft, ipsilateral measurements were compared and the ability to restore corresponding glenoid bone loss was calculated. Results Distal clavicle grafts were larger than coracoid grafts with respect to length (22.3 mm versus 17.7 mm; p < 0.001), height (12.49 mm versus 9.65 mm; p < 0.001), mass (2.72 g versus 2.45 g; p = 0.0437), and volume (2.36 cm3 versus 1.96 cm3; p = 0.002). Coracoid grafts had larger widths (14.56 mm versus 10.52 mm; p < 0.001) and greater density (1.24 g/cm3 versus 1.18 g/cm3; p < 0.001). Distal clavicle surface area was greater on both the articular (2.93 cm2 versus 1.5 cm2; p < 0.001) and superior surfaces (2.76 cm2 versus 1.5 cm2; p < 0.001) when compared to lateral coracoid surface area. Discussion Distal clavicle grafts were larger and restored larger bony defects but had greater variability and lower density than coracoid grafts. Clinical studies are needed to compare these graft options.

“…Next, the Latarjet procedure was performed using the classic technique through a subscapularis split and with the inferior aspect of the coracoid placed flush with the face of the glenoid. 9,12,23 The coracoacromial ligament was cut sharply with a No. 15 blade, 1 cm lateral to its insertion on the coracoid, so that a sleeve of the coracoacromial ligament would be available for repair as described in the classic technique.…”

“…A modification to this technique, termed the congruent arc modification, rotates the coracoid 90 degrees so that the medial surface of the coracoid is apposed to the anterior glenoid. Table 1 lists the relative advantages and disadvantages of each technique [18,19].…”

Purpose of Review The purpose of this paper is to evaluate the recent evolution in the treatment of anterior shoulder instability and the dynamic interaction between the glenoid and HillSachs lesion. Recent Findings Through the glenoid track concept, glenoidand humeral-sided bone loss are evolving away from being approached as separate entities. Recent cadaveric studies have validated the glenoid track concept. Moreover, a recent clinical study has demonstrated a much higher rate of failure after arthroscopic Bankart repair for shoulders that were off track. Summary The glenoid track concept is a useful tool in evaluating patients with anterior shoulder instability. Shoulders that are off track may require more than a simple arthroscopic Bankart, and the addition of a remplissage or bony transfer may be considered.
