Objective: The aim is to present a modified arthroscopic remplissage for shoulder Hill-Sachs lesions with high-strength sutures instead of suture anchors, to achieve better tendon-bone healing and avoid failure of remplissage due to anchor detachment., Material and Methods: A total of seven patients with recurrent anterior shoulder dislocation combined with a Hill-Sachs lesion were included in this study. Firstly, anteroinferior glenoid labrum complex damage was treated then 2-3 bone tunnels were punched with a sighting device from the bony defect of the humeral head to the inside of lesser tubercles of the humerus. The bony defect was filled by stitching the infraspinatus tendon through the bony tunnels with high-strength sutures. After the operation, the filling and healing of the infraspinatus tendon in the Hill-Sachs lesion were assessed using magnetic resonance imaging (MRI)., Results: Patients were followed up for 12 months. The results of MRI showed that all of the filled tendons healed well. Postoperative external rotation of the shoulder joint increased on average from 67° to 87°. Compared with the preoperative level, the Oxford Shoulder Instability Score (OSIS) was 18.50 ± 1.04 points higher and the Rowe score was increased by 66.755 ± 0.914 points., Conclusion: Arthroscopic remplissage of a shoulder Hill-Sachs lesion with high-strength sutures carries the benefits of secure fixing and good tendon-bone healing without the risk of anchor detachment.

Purpose: We aimed to investigate the clinical performance of the constructs of double-door cervical laminoplasty with suture anchors by examining bony fusion at the hinges and lamina closure., Methods: We retrospectively analysed computed tomography (CT) scans obtained preoperatively, immediately after the operation, and at follow-up of patients who underwent cervical laminoplasty using suture anchors. Hinge fracture, bony healing at the hinges, suture anchor failure, and the lamina angle (LA) were evaluated using CT. Lamina closure was defined as an LA <55° at follow-up., Results: A total of 226 laminae and hinges from 37 patients were evaluated. CT scans immediately after the operation revealed that 13 laminae (5.8 %) were fractured, one of which collapsed into the spinal canal. Bony fusion at an average of 12.7 months after the operation was noted at 222 hinges (98.2 %), which was not affected by hinge fracture. One dislodged suture anchor was identified. The mean LAs were 34.4 ± 4.2° preoperatively, 87.4 ± 12.3° immediately after the operation, and 82.5 ± 12.9° at follow-up. At follow-up, four cases of lamina closure were identified (1.8 %), and the closure rate was significantly higher at C3 than at the other levels, although it was not affected by age, sex, causative disease, cervical alignment, suture anchor use, and hinge fracture., Conclusions: The constructs of double-door cervical laminoplasty with suture anchors are stable with a high rate of fusion at the hinges. However, if the procedure is performed at C3, special modifications should be made to avoid lamina closure.
