The "Sublabral Window" in Arthroscopic Posterior Shoulder Instability Surgery: Description of a Technique for Safe Posterior Glenoid Preparation.

ABSTRACT: Arthroscopic posterior labral repairs for posterior shoulder instability can be challenging. Preparation of the capsulolabral tissue and glenoid bony surface is critical. Iatrogenic injury to the articular cartilage and unwarranted truncation of the capsulolabral tissue are concerns during preparation. As a result, several techniques have been described to potentially avoid these complications. We describe an additional technique for improving access and preparing the capsulolabral tissue and glenoid surface through a "sublabral window." This technique approaches the posterior labrum and glenoid through an already established posterior portal and mitigates iatrogenic injury to the labrum and articular cartilage. The technique is rather simple and easily adaptable.

Arthroscopic "Bone Block Cerclage" Technique for Posterior Shoulder Instability.

Project description: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 distal tibial allograft augmentation for posterior shoulder instability with glenoid bone loss.

Project description:Glenoid bone loss is commonly associated with recurrent shoulder instability. Failure to recognize and appropriately address it can lead to poor outcomes. Numerous studies have found anterior-inferior glenoid bone loss in the setting of recurrent anterior instability. Though much less common, posterior shoulder instability can be seen in the setting of acute trauma, epilepsy, electrocution, and alcoholism. Heightened awareness has led to recognition in collision athletes as well. Posterior glenoid bone loss must be addressed in a similar fashion to anterior glenoid bone loss to prevent recurrent instability. Open bone augmentation procedures have been described with successful results. In this technical note, we describe an arthroscopic technique using fresh distal tibial allograft for posterior glenoid augmentation. In addition, a current review regarding the diagnosis and management of recurrent posterior shoulder instability is provided.

Arthroscopic Bone Block Procedure for Posterior Shoulder Instability: Updated Surgical Technique.

Project description:Posterior shoulder instability is generally caused by traumatic posterior dislocations or repetitive microtrauma during sports or other activities and has an annual incidence rate of 4.64 per 100,000 person-years. Several surgical techniques to treat posterior shoulder instability have been described, including soft-tissue repair and both open and arthroscopic bone block procedures. However, even though patient-reported outcomes are commonly high, surgical procedures are associated with high complication and revision rates of up to 14% and 67%, respectively. In particular, accurate placement of the bone graft, screw orientation, and the treatment of concomitant lesions are considered challenging. Therefore, improvement of surgical techniques is desirable. This Technical Note describes an updated approach to the arthroscopic posterior bone block augmentation described by Lafosse et al. (2012), with tips and tricks on the harvest and positioning of the graft.

Posterior Shoulder Instability but Not Anterior Shoulder Instability Is Related to Glenoid Version.

Project description:PurposeTo assess and compare glenoid version in patients with anterior shoulder instability (ASI), posterior shoulder instability (PSI), and a control group.MethodsThe operative notes of all patients that had undergone arthroscopic shoulder instability repair between January 2017 and May 2022 were retrospectively reviewed. Magnetic resonance imaging scans were then analyzed, and glenoid version was measured by a single blinded observer. A P value <.05 was considered statistically significant.ResultsThere were 100 patients included in the ASI group, 65 in PSI group, and 100 in the control group. The mean glenoid versions for the ASI group were -16°, -9.1°, and -9.2° for the vault version, simplified vault version, and chondrolabral version, respectively. The mean glenoid versions for the PSI group were -21°, -13.4°, and -16.6° for the vault version, simplified vault version, and chondrolabral version, respectively. The mean versions for the control group were -17.8°, -9.5°, and -9.8° for the vault version, simplified vault version and chondrolabral version, respectively. ANOVA testing and post hoc comparisons revealed the PSI group to be significantly more retroverted than both other groups P < .001. The ASI group's degree of glenoid version was not significantly different to that of the control P = .009.ConclusionPatients with PSI have a higher degree of retroversion in comparison to those with ASI and control. There is no significant difference in glenoid version among patients with ASI when compared with control.Level of evidenceLevel III, retrospective comparative study.

Arthroscopic Knotless Subscapularis Bridge Technique for Reverse Hill-Sachs Lesion With Posterior Shoulder Instability.

Project description: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.

Arthroscopic Glenoid Bone Augmentation Using Iliac Crest Autograft Is Safe and Effective for Anterior Shoulder Instability With Bone Loss.

Project description:PurposeTo establish a safety profile for an arthroscopic anatomic glenoid reconstruction using autologous iliac crest bone graft to treat shoulder instability with significant bone loss and to evaluate short-term clinical and radiological outcomes.MethodsA retrospective analysis of prospectively collected data was conducted for the patients who were treated for shoulder instability with bone loss using arthroscopic autologous iliac crest bone graft between November 2014 and June 2018. The safety profile was established by detective intraoperative or postoperative complications such as neurovascular injuries, infections, major bleeding, and subluxations. Short-term clinical and radiologic outcomes also were evaluated.ResultsThirteen patients were included in the study. A safety profile was observed, with no occurrence of intraoperative complications, neurovascular injuries, infection, or major bleeding. There were no dislocations or positive apprehension tests on clinical examination postoperatively. Postoperative Western Ontario Shoulder Instability (WOSI) scores were significantly greater than preoperative WOSI scores, with a mean improvement of 35.0 ± 20.2 (P < .001). Twelve patients (92.3%) received postoperative computed tomography scans, with 11 of 12 patients (91.7%) displaying complete graft union.ConclusionsArthroscopic treatment of shoulder instability with bone loss via autologous iliac crest bone graft is shown to be a safe operative procedure that results in favourable short-term clinical and radiologic outcomes, with a significant improvement in WOSI scores and high rates of graft union. Although graft resorption was seen in most patients who had postoperative computed tomography imaging, there were no instances of clinical graft failure.Level of evidenceLevel IV, therapeutic case series.

Posterior Glenoid Augmentation With Extra-articular Iliac Crest Autograft for Recurrent Posterior Shoulder Instability.

Project description:Several techniques have been described for bone block augmentation as a treatment for posterior shoulder instability, including intra-articular distal tibial allograft and extra-articular iliac crest autograft. Although indications are not yet well defined, these bone augmentation procedures are considered in patients with glenoid bone loss, increased glenoid retroversion, previous failed posterior soft-tissue repair, and insufficient posterior capsulolabral tissue. In patients with posterior glenoid bone loss, the senior author (P.J.M.) recommends intra-articular glenoid reconstruction with a fresh distal tibial osteoarticular allograft. In patients with insufficient posterior capsulolabral tissue, the senior author prefers an extra-articular iliac crest autograft to buttress the posterior soft-tissue restraints. This technique guide outlines extra-articular iliac crest autograft treatment for recurrent posterior shoulder instability in patients with insufficient posterior soft tissues due to prior failed surgery. After an open capsulolabral repair is performed using suture anchors, the bone block is placed extra-articularly on the posterior glenoid neck.

Arthroscopic Posterior Glenoid Reconstruction Using a Fresh Distal Tibia Allograft for Recurrent Posterior Instability.

Project description:Posterior glenohumeral instability is a relatively uncommon cause of shoulder instability. Recurrent posterior instability with static posterior humeral head subluxation is often associated with critical glenoid bone loss. Unlike anterior instability, the amount of bone loss for posterior instability that requires surgical reconstruction remains a topic of debate. Several techniques have been described to treat critical bony defects in patients with recurrent posterior shoulder instability with the use of both autografts and allografts depending on the amount of bone loss present. Open posterior glenoid bone block procedure is associated with increased risk of complications and morbidity to the patient. As such, all-arthroscopic techniques have emerged with the advantage of allowing for the diagnosis and treatment of concomitant glenohumeral pathology and minimizing soft-tissue dissection through the posterior deltoid and rotator cuff muscles. Reported short-term outcomes of arthroscopic posterior bone block stabilization are promising; however, it remains a technically challenging procedure due to intra-articular graft insertion and subsequent fixation congruent to the posterior glenoid articular margin. We describe an all-arthroscopic technique using a fresh distal tibia allograft fixation using 2 partially threaded screws in conjunction with an arthroscopic Latarjet fixation set for a patient with recurrent posterior shoulder instability and associated glenoid bone loss.

Arthroscopic distal clavicular autograft for treating shoulder instability with glenoid bone loss.

Project description:Glenoid bone loss is a significant risk factor for failure after arthroscopic shoulder stabilization. Multiple options are available to reconstruct this bone loss, including coracoid transfer, iliac crest bone graft, and osteoarticular allograft. Each technique has strengths and weaknesses. Coracoid grafts are limited to anterior augmentation and, along with iliac crest, do not provide an osteochondral reconstruction. Osteochondral allografts do provide a cartilage source but are challenged by the potential for graft rejection, infection, cost, and availability. We describe the use of a distal clavicular osteochondral autograft for bony augmentation in cases of glenohumeral instability with significant bone loss. This graft has the advantages of being readily available and cost-effective, it provides an autologous osteochondral transplant with minimal donor-site morbidity, and it can be used in both anterior and posterior bone loss cases. The rationale and technical aspects of arthroscopic performance will be discussed. Clinical studies are warranted to determine the outcomes of the use of the distal clavicle as a graft in shoulder instability.

Arthroscopic Bone Block Cerclage Technique Using a Tricortical Scapular Spine Autograft for Glenoid Reconstruction in Patients With Anterior Shoulder Instability.

Project description:In the treatment of anterior shoulder instability with glenoid bone loss, free bone graft transfers have proven to be a viable anatomic alternative to the commonly performed, nonanatomic Latarjet procedure. Implant-free fixation of the free bone grafts, in particular, has rendered excellent short- and long-term results. However, a drawback remains the source of the graft. We describe an arthroscopic bone block cerclage technique using a tricortical scapular spine autograft, which provides an anatomic arthroscopic glenoid reconstruction with the combined benefit of sparing the subscapularis, metal-free fixation, and intraregional donor site for autograft harvesting.
