ABSTRACT

Background: The 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.

Methods: Between 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.

Results: All 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.

Conclusion: The 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 PMM Fascia (blue illustration) is Incised and Flipped Laterally (a, b). The CAL (yellow illustration) is stitched to the PMM with strong Vicryl™ sutures (c, d). This is called the pectoralis minor fascia flap. CAL, coracoacromial ligament; PMFF, pectoralis minor fascia flap; PMM, pectoralis minor muscle

Mentions: For reconstruction of the CAL, the PMM fascia is incised longitudinally for about 5 cm and a triangular shape created with a medial base of about 2–3 cm. The fascia is carefully detached from the muscle and is left attached distal to the coracoid. This PMFF is flipped over to the lateral side, where it is attached to the stump of the CAL (Fig. 8). The PMFF is usually wide enough to be doubled, strengthening the structure. The PMFF and CAL are stitched together with strong Vicryl™ sutures with maximal overlap and tension.Fig. 8
