“… 13 Patients with bipolar bone loss are disproportionately predisposed to greater rates of recurrent dislocation, necessitating distinct treatment paradigms. As bony augmentation treatment options evolve for both anterior and posterior humeral lesions, 14 the ability of surgeons to treat concomitant anterior and posterior lesions has dramatically increased, although it has not been previously described.…”

“…The management of glenoid bone deficiency is critical when treating shoulder instability. 5,18 Glenoid bone loss is the most important factor that surgeons consider when deciding whether to perform a bony procedure. 14 Studies have found that defects as small as 13.5% have been associated with recurrent instability after arthroscopic stabilization and worse outcomes, 7,23 emphasizing the importance of accurately measuring bony defects and autografts for operative planning.…”

Distal Clavicle Autograft Versus Traditional and Congruent Arc Latarjet Procedures: A Comparison of Surface Area and Glenoid Apposition With 3-Dimensional Computed Tomography and 3-Dimensional Magnetic Resonance Imaging

et al. 2023

Background: Limited studies have compared graft-glenoid apposition and glenoid augmentation area between the Latarjet procedure and distal clavicle graft in glenohumeral stabilization. Additionally, preoperative planning is typically performed using computed tomography (CT), and few studies have used 3-dimensional (3D) magnetic resonance imaging (MRI) reformations to assess graft dimensions. Purpose: The purpose of this study was 2-fold: (1) to compare bony apposition, glenoid augmentation, and graft width among coracoid and distal clavicle bony augmentation techniques and (2) to determine the viability of 3D MRI to assess bone graft dimensions. Study Design: Controlled laboratory study. Methods: A total of 24 patients with recurrent glenohumeral instability and bone loss were included in this study. 3D CT and 3D MRI reformations were utilized to measure pertinent dimensions for 5 orientations of coracoid and distal clavicle autografts: (1) standard Latarjet procedure (SLJ), (2) congruent arc Latarjet procedure (CLJ), (3) distal clavicle attached by its posterior surface (DCP), (4) distal clavicle attached by its inferior surface (DCI), and (5) distal clavicle attached by its resected end (DCR). Glenoid augmentation was defined as the graft surface area contributing to the glenoid. Bone-on-bone apposition was defined as the graft-glenoid contact area for bone healing potential, and graft width was pertinent for fixation technique. Glenoid bone loss ranged from 0% to 34%. Paired t tests were used to compare graft sizes between patients and compare 3D CT versus 3D MRI measurements. Results: The CLJ had the largest graft surface area (mean, 318.41 ± 74.44 mm2), while the SLJ displayed the most bone-on-bone apposition (mean, 318.41 ± 74.44 mm2). The DCI had the largest graft width (mean, 20.62 ± 3.93 mm). Paired t tests revealed no significant differences between the Latarjet techniques, whereas distal clavicle grafts varied significantly with orientation. All 3D CT and 3D MRI measurements were within 1 mm of each other, and only 2 demonstrated a statistically significant difference (coracoid width: 13.03 vs 13.98 mm, respectively [ P = .010]; distal clavicle thickness: 9.69 vs 10.77 mm, respectively [ P = .002]). 3D CT and 3D MRI measurements demonstrated a strong positive correlation ( r > 0.6 and P < .001 for all dimensions). Conclusion: Glenoid augmentation, bony apposition, and graft width varied with coracoid or distal clavicle graft type and orientation. Differences between 3D CT and 3D MRI were small and likely not clinically significant. Clinical Relevance: 3D MRI is a viable method for preoperative planning and graft selection in glenoid bone loss.

“…It can also be considered the treatment of choice in patients without glenoid defect if they are deemed to have a high risk of dislocation if treated with soft tissue procedures ( 2 , 3 ). As a result of these indications, the number of Latarjet procedures performed has increased exponentially in the last decades ( 4 , 5 ).…”

“…The height of the graft is determined by the percentage that is located above or under the equator of the glenoid. The major part of the graft should be subequatorial, with an optimal location at about 4 or 5 o’clock ( 4 ). The position with respect to the glenoid surface is determined in the axial plane and should be flush with the articular surface ( 7 ).…”

Recurrence of instability after Latarjet procedure: causes, results and treatment algorithm

Latarjet modifies the anatomy of the shoulder, and subsequent revision surgery is challenging. It is mandatory to determine the cause of recurrence in order to select the best treatment option. A CT scan is needed to measure glenoid track and evaluate coracoid graft status: position, degree of consolidation, and osteolysis. Conservative management can be advocated in selected patients in whom the instability level does not interfere with the activities they wish to perform. Surgical treatment is based on the glenoid track measurement and coracoid graft suitability. The coracoid graft is considered suitable if it preserves the conjoint tendon insertion, does not show osteolysis, and is large enough to reconstruct the glenoid surface. Adding a remplissage is recommended for those cases with a coracoid graft insufficient to convert large off-track Hill–Sachs lesions into on-track. If the coracoid graft is suitable to reconstruct bone defects in terms of size and viability but is poorly positioned or avulsed, graft repositioning can be a valid option. In patients with unsuitable coracoid bone graft, free bone graft is the revision technique of choice. The size of the graft should be large enough to restore the glenoid surface and to convert any off-track Hill–Sachs lesion into on-track. There is a small group of patients in whom bone defects were properly addressed but Latarjet failed due to hyperlaxity or poor soft tissue quality. Extraarticular capsular reinforcement is suggested in this population.
