Arthroscopic Posterior Glenoid Osteotomy
Management of posterior shoulder instability in patients with excessive glenoid retroversion can be challenging. However, a corrective posterior glenoid osteotomy is an option. Although various open techniques are available, minimally invasive and arthroscopy surgery are the most advantageous. This study describes the feasibility and safety of an arthroscopic posterior open wedge glenoid osteotomy using an autologous scapular spine graft along with additional posterior capsulolabral complex reattachment. This procedure is a viable option for patients with symptomatic posterior shoulder instability
Arthroscopic Bone Block Cerclage: A Fixation Method for Glenoid Bone Loss Reconstruction Without Metal Implants
Large glenoid bone loss defects are associated with higher failure rates after arthroscopic Bankart repair in cases of glenohumeral anterior instability, further necessitating bone graft reconstruction. Because most techniques use strong initial fixation using metal devices, bone graft resorption considered to be closely related to the presence of metal components is a potential shortcoming of these techniques. We describe an arthroscopic technique for anatomical reconstruction of the glenoid that uses a tricortical iliac crest with a metal-free fixation method using 2 ultra-high-strength sutures (FiberTape Cerclage System; Arthrex, Naples, FL), which provide substantial stability to the graft, and finishing with a capsulolabral reconstruction
Latarjet Cerclage: The All-Arthroscopic Metal-Free Fixation
The Bristow-Latarjet procedure has been one of the most recognized procedures for the treatment of recurrent shoulder dislocation with anterior glenoid bone loss, revision surgery after failed Bankart repair, contact and collision sport injuries, and patients with a high risk of recurrence. Open and arthroscopic approaches have recently shown similar outcomes by several authors. However, complications related to metal implants, despite being low, are still a matter of concern. We describe an all-arthroscopic Latarjet technique with a metal-free fixation method using 2 ultra-high-strength sutures, creating a cerclage construct through 2.4mm glenoid and coracoid tunnels with a final capsulolabral complex reconstruction
Latarjet Cerclage: The Metal-Free Fixation
The Latarjet technique is a widely used technique for anterior shoulder instability with glenoid bone defects, irreparable capsuloligamentous lesion, or in patients at greater risk of recurrence. The use of this technique has been reported to obtain satisfactory clinical and biomechanical results. Although other methods exist, the coracoid process is typically fixed with 2 metal screws. Complications related to metal fixation are very frequently reported. In an attempt to avoid these complications, we developed this arthroscopically assisted metal-free Latarjet technique in which we fix a coracoid graft using four cerclage tapes to achieve a strong, stable fixation, thus mimicking a plate
Arthroscopic "Bone Block Cerclage" Technique for Posterior Shoulder Instability
Many open and arthroscopic techniques have been described to treat posterior glenohumeral instability. Multifactorial features of posterior shoulder instability pathoanatomy and varied patient characteristics have challenged the understanding of this condition and have led to dissimilar results, without a strong consensus for the most adequate technique to treat it. We describe an arthroscopic anatomical metal-free posterior glenoid reconstruction technique, using a tricortical iliac crest allograft with 2 ultra-high strength sutures (FiberTape Cerclage System; Arthrex, Naples, FL) with concomitant posterior capsulolabral complex reconstruction procedure
Arthroscopic Knotless Subscapularis Bridge Technique for Reverse Hill-Sachs Lesion With Posterior Shoulder Instability
Posterior shoulder dislocations are an uncommon cause of glenohumeral instability; they are frequently missed and are associated with humeral head defects and capsulolabral lesions. Despite surgical treatment often being mandatory, there is still no standardized treatment for anterior impaction fractures of the humeral head (reverse Hill-Sachs lesions). Arthroscopic surgery is typically indicated, with a tendency toward resorting to knotless techniques in recent years. We present a method for the treatment of posterior shoulder dislocations with engaging reverse Hill-Sachs lesions that achieves full defect coverage using an arthroscopic all-in-the-box knotless subscapularis bridge technique with 2 anchors-with one crossing the subscapularis tendon and the other embracing it-along with posterior capsulolabral complex restoration. This promising technique is a potentially superior alternative for the treatment of these lesions that can also be used in the presence of concomitant partial subscapularis tears
Arthroscopically Assisted Comprehensive Double Cerclage Suture Fixation Technique for Acute Acromioclavicular Joint Separation
Acromioclavicular dislocations are some of the most frequently recorded and controversial injuries in the athletic population. These injuries have historically been a matter of disagreement between surgeons, particularly when it comes to the surgical technique used to treat them, its approach, or its timing. Consensus over the "gold standard" procedure to treat them is yet to be established. Even though numerous surgical techniques have already been described, the number of complications and loss of reduction remains a matter of concern for treating physicians. Here, we present an arthroscopically assisted coracoclavicular and horizontal acromioclavicular fixation technique in a modified figure-of-eight configuration using 2 strong FiberTape Cerclage sutures, with measurable tension, for the comprehensive treatment of acromioclavicular joint dislocations
Open Latarjet with Metal-Free Cerclage Fixation
Despite multiple modifications, the Latarjet is still the most popular procedure for recurrent anterior shoulder instability with glenoid bone loss. Partial or subtotal resorption of the graft is common, potentially leading to hardware prominence and risk of anterior soft-tissue impingement. To minimize the technical difficulties and morbidity associated with metallic implants, a coracoid and conjoint tendon transfer with a mini-open approach using Cerclage tape suture is described, as an alternative for the Latarjet procedure typically performed with metal screws and plates
Arthroscopic All-Inside Remplissage Technique With Knotless Tape Bridge for Hill-Sachs Lesions
The arthroscopic remplissage procedure has been described to successfully treat engaging Hill-Sachs lesions and improve shoulder stability. Several variations of this technique have been described, including remplissage with 1 or 2 knotted or knotless anchors, remplissage with double or triple bridging pulleys, and remplissage with or without a subacromial view. However, most techniques use anchors in combination with round sutures. This article describes an allarthroscopic articular knotless remplissage technique using a strong, flat, double-strand suture tape bridge fixed with 2 small anchors under direct joint visualization and reduction of the capsule and infraspinatus without requiring a subacromial view
Comprehensive management of posterior shoulder instability: diagnosis, indications, and technique for arthroscopic bone block augmentation
Recurrent posterior glenohumeral instability is an entity that demands a high clinical suspicion and a detailed study for a correct approach and treatment. Its classification must consider its biomechanics, whether it is due to functional muscular imbalance or to structural changes, volition, and intentionality. Due to its varied clinical presentations and different structural alterations, ranging from capsule-labral lesions and bone defects to glenoid dysplasia and retroversion, the different treatment alternatives available have historically had a high incidence of failure. A detailed radiographic assessment, with both CT and MRI, with a precise assessment of glenoid and humeral bone defects and of glenoid morphology, is mandatory. Physiotherapy focused on periscapular muscle reeducation and external rotator strengthening is always the first line of treatment. When conservative treatment fails, surgical treatment must be guided by the structural lesions present, ranging from soft tissue repair to posterior bone block techniques to restore or increase the articular surface. Bone block procedures are indicated in cases of recurrent posterior instability after the failure of conservative treatment or soft tissue techniques, as well as symptomatic demonstrable nonintentional instability, presence of a posterior glenoid defect >10%, increased glenoid retroversion between 10 and 25 degrees, and posterior rim dysplasia. Bone block fixation techniques that avoid screws and metal allow for satisfactory initial clinical results in a safe and reproducible way. An algorithm for the approach and treatment of recurrent posterior glenohumeral instability is presented, as well as the author's preferred surgical technique for arthroscopic posterior bone block
