“…However, when the coracoid thickness (8.4–11 mm or ~60 % of its width) is considered, it becomes apparent that the congruent-arc procedure produces a cantilevered geometry with a smaller contact area with the native glenoid, which may predispose to graft fixation issues. Our results showed that the coracoid width was longer than its height, similar to the conclusions of Degen et al [17]. Nevertheless, based on multiple linear regression analysis, we concluded that the safety margin was proportional to the cadaver’s height, and the coracoid tip and midpoint height were inversely proportional to the cadaver’s height.…”

BackgroundThe Latarjet procedure addresses recurrent anterior shoulder instability in the context of a significant bony defect. However, the bony and soft tissue anatomy of the coracoid in coracoid transfer procedures has not yet been defined in Mongolian men. The aims of this study were to describe the soft tissue attachments of the coracoid regarding the bony anatomy, define the average amount of bone available for coracoid transfer, analyze the characteristics of the pectoralis minor and coracoid, and study the relationship between the bony dimensions of the coracoid and body length in Mongolian men.MethodsWe dissected 30 shoulders from 15 male Mongolian cadavers, exposing the coracoid process and attached anatomical structures including the lateral clavicle and acromion, then measured the bony dimensions of the coracoid and the locations and sizes of the coracoid soft tissue footprints.ResultsThe mean length of the coracoid available for transfer was 23.93 ± 2.32 mm. The mean length of the coracoid was 42.10 ± 2.3 mm, and the mean width and height of the coracoid midpoint were 15.29 ± 1.70 mm and 11.61 ± 1.98 mm, respectively. The pectoralis minor was part of the joint capsule and passed over the coracoid in some samples. The mutation rate of the pectoralis minor footprint, which was asymmetrical and irregular, was 23.33 %. Statistical analysis involved a multiple linear regression equation.ConclusionsThe average amount of bone available for use in coracoid transfer in Mongolian men was less than that of other populations. Mutation of the pectoralis minor may induce intraoperative capsule injury because this muscle passes over the coracoid deep to the joint capsule of the glenohumeral joint and constitutes part of the shoulder joint, strengthening the joint. Statistically, higher coracoids appeared in shorter patients and longer coracoids appeared in taller patients. Surgically, great care should be taken to consider a patient’s height to precisely implement the congruent-arc Latarjet technique.

“…Because of the matching radius of curvature and the potential for greater bony conformity and constraint, it is conceivable that the CP oriented in a congruent manner could decrease superior humeral head translation. The study by Degen et al [ 8 ], however, indicates that the congruent-arc modification and the classic Latarjet did not differ significantly ( P > 0.05) with regard to superior translation.…”

“…A recent study indicates that performing a Latarjet procedure can lead to an increase in superior shoulder translation in most joint configurations and loading conditions [ 8 ]. This highlights the importance of the CAL as a restraint to superior humeral head translation, even in patients with an intact rotator cuff.…”

BackgroundThe coracoacromial ligament (CAL) is an important restraint to superior shoulder translation. CAL release with the Latarjet procedure leads to increased superior humeral translation. Therefore, a surgical technique was developed to reconstruct the CAL during a modified Latarjet procedure.MethodsBetween May 2010 and July 2011, six patients (five were male, one was female; age 23–41 years) with chronic post-traumatic anterior shoulder instability were treated surgically with a modified congruent-arc Latarjet procedure (modLAT) with additional reconstruction of the CAL using a newly developed procedure, the pectoralis minor fascia flap (PMFF). Clinical follow-up was performed for up to 36 months, and patients were evaluated using a Rowe score.ResultsAll six patients experienced chronic, post-traumatic anterior shoulder instability and had experienced multiple re-dislocations after initial treatment. The preoperative assessment showed a defect of the anterior glenoid in three cases, and the mean Rowe score was 16.67 (5–25). Open modLAT with PMFF resulted in a stable shoulder function with no re-dislocations. The Rowe score increased from 77.5 (65–90) at 12 weeks to 95 (90–100) at 12 months and plateaued thereafter. Operative duration was 95 min (78–112 min), and there were no intra- or postoperative complications. All patients returned to their preoperative sports activity, three at the same level.ConclusionThe PMFF is a safe technique for reconstruction of the CAL during a modLAT procedure. Patients had improved shoulder function and no re-dislocations after the surgery.

“…The role of the integrity of the CA arch in superior shoulder stability has been illustrated in several studies, with the finding that CA ligament resection or performing the Latarjet procedure resulted in increased superior shoulder translation in various joint configurations and loading conditions, regardless of whether or not the rotator cuff was intact. 6 , 7 , 9 , 13 , 14 , 15 Preservation of the CA arch during the Latarjet procedure is an ideal, but impossible, option.…”

Arthroscopic Transfer of the Long Head of the Biceps Brachii for Anterior Shoulder Instability

In the treatment of anterior shoulder instability, there are various conditions in which a sling effect is needed to enhance anterior stability. The traditional Latarjet procedure provides a sling effect but destroys the coracoacromial arch, which may result in superior instability. To preserve the coracoacromial arch and create a sling to enhance the anterior-inferior side of the shoulder, we introduce an arthroscopic technique to transfer the long head of the biceps (LHB) brachii. Indications of LHB transfer are patients younger than 45 years of age who participate in competitive sports, require forceful external rotation and abduction movement of the shoulder, and/or have capsule-ligament insufficiency, as well as patients 45 years o or older who have combined SLAP lesions (type II or IV). The main steps of this procedure include detaching the LHB, retrieving and braiding the LHB, creating a glenoid tunnel, placing a guide suture through the subscapularis and glenoid tunnel, passing the LHB through the subscapularis and into the glenoid tunnel, and suspension fixation of the LHB.
