Arthroscopic Distal Clavicular Autograft for Congruent Glenoid Reconstruction

ABSTRACT: Arthroscopic distal clavicular autograft (DCA) is effective in shoulder instability with glenoid bone loss. The original technique uses an osteochondral autograft, fixed with screws or suture anchors. We developed a modified procedure called “congruent arc DCA” characterized by (1) use of drilling guides to optimize graft positioning and make the all-arthroscopic procedure safer and reproducible; (2) rotation of the DCA of 90° to reach a congruent arc with its undersurface; (3) fixation of the graft with cortical buttons to simplify its intra-articular passage, avoid hardware problems, and facilitate possible revision surgery; and (4) intraoperative use of a suture tensioner to achieve satisfactory compression of the graft and increase its consolidation. Technique Video Video 1 Arthroscopic distal clavicular autograft for congruent glenoid reconstruction. We present our modified procedure called “congruent arc DCA,” characterized by 5 steps: (1) opening the rotator interval, (2) glenoid preparation and drilling, (3) distal clavicle dissection, drilling and osteotomy, (4) clavicle bone graft transfer and fixation, and (5) Bankart repair. The patient is positioned in “lazy” beach chair and arthroscopic images are all from a right shoulder.

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 Posterior Glenoid Reconstruction With Distal Clavicle Bone-Block.

Project description:Posterior glenoid bone loss is a potential cause for failure in arthroscopic capsulolabral repair. Although multiple techniques have been described to reconstruct posterior bone defects, they do not reliably yield improved patient outcomes and have high complication rates. We present a technique to reconstruct posterior glenoid bone loss using a distal clavicle autologous bone graft harvested by a mini-open approach and secured arthroscopically with suture buttons. The graft is positioned extra-articularly by repairing the posterior labral complex with a knotless fixation using labral tape.

Arthroscopic Anatomic Glenoid Reconstruction With Distal Tibial Allograft and Hybrid Fixation.

Project description:Glenoid grafting is the standard surgical treatment for recurrent shoulder instability with significant glenoid bone loss. Arthroscopic anatomic glenoid reconstruction using a distal tibial allograft for anatomic glenoid reconstruction has recently been gaining attention. This article describes the use of a hybrid graft fixation technique with 1 suture-EndoButton device and 1 compression screw in arthroscopic anatomic glenoid reconstruction using distal tibial allograft.

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 Anatomic Glenoid Reconstruction in the Setting of a Failed Latarjet Using Distal Tibial Allograft.

Project description:Treatment of traumatic anterior glenohumeral dislocation has evolved over the years in terms of surgical approaches and methods of repair. Recurrence of instability following surgical repair remains challenging with conventional methods of open reconstruction. We describe the utilization of arthroscopic anatomic glenoid reconstruction using a distal tibial allograft after a failed Latarjet procedure. Preoperative and operative methodology are described with relevant imaging investigations and a detailed intraoperative arthroscopic technique.

Arthroscopic labral reconstruction with gracilis autograft.

Project description:Despite growing interest in hip arthroscopy and labral preservation, some patients have severely damaged, degenerative, or deficient labrums and may be candidates for arthroscopic labral reconstruction. The ligamentum teres has been used as a graft source for open hip labral grafting, and the iliotibial band has been used in the arthroscopic setting. We present an alternative method of hip labral reconstruction using the gracilis autograft, which does not require post-harvest manipulation. Arthroscopic techniques for graft tensioning and labrum-graft overlap are introduced that may facilitate restoration of labral function in patients with otherwise non-salvageable labrums.

Graft Transfer Technique in Arthroscopic Posterior Glenoid Reconstruction With Distal Tibia Allograft.

Project description:Posterior glenoid reconstruction using distal tibia allograft is an available technique for the treatment of posterior shoulder instability with glenoid bone loss. A key aspect to this procedure relies on maintaining complete control of the graft during insertion and securement to the posterior glenoid. Although there are commercially available products to aid with graft control, we describe a novel graft transfer technique that is compatible with all cannulated systems for maintaining positive graft control. This technique allows the surgery to be performed in an arthroscopic manner using current instrumentation for open glenoid reconstruction.

Arthroscopic Anatomic Glenoid Reconstruction Without Subscapularis Split.

Project description:The role of bone loss from the anterior glenoid in recurrent shoulder instability has been well established. We present a completely arthroscopic technique for reconstructing the anterior glenoid with distal tibial allograft and without a subscapularis split. We perform the arthroscopy in the lateral position. We measure and size an allograft distal tibial graft and place it arthroscopically. We use an inside-out medial portal to introduce the graft into the shoulder, passing it through the rotator interval and above the subscapularis. A double-cannula system is used to pass the graft, which is temporarily fixed with K-wires and held in place with cannulated screws. We then perform a Bankart-like repair of the soft tissues to balance the shoulder and augment our repair. Our technique is not only anatomic in the re-creation of the glenoid surface but also anatomic in the preservation of the coracoid and subscapularis tendon and repair of the capsulolabral complex.

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.

Arthroscopic Revision with Autologous Iliac Crest Bone Graft for Failed Anatomic Glenoid Reconstruction Using Distal Tibia Allograft.

Project description:Recurrent instability after anterior shoulder stabilization surgery is not an uncommon complication, with variable rates of recurrences associated with different surgical procedures. The Latarjet procedure continues to be the gold standard in the management of anterior instability with significant glenoid bone loss, although a recent trend toward arthroscopic anatomic glenoid reconstruction (AAGR) with distal tibial allograft has been noted, with excellent short-term results and minimal complication rates. Arthroscopic revision stabilization for failed stabilization procedures is increasingly being performed, although it is technically more challenging than the primary stabilization procedure because of the anatomic rearrangements of the index surgery. In this article, we describe a revision arthroscopic technique for anatomic glenoid reconstruction using iliac crest autograft for a previous failed AAGR procedure secondary to nonunion of the graft. The graft is passed through the Halifax far-medial portal without splitting the subscapularis. Arthroscopic revision in the setting of a failed AAGR procedure is technically easier than after a Latarjet procedure, as the anatomy is relatively undisturbed in the former, facilitating easier identification of anatomic landmarks, accurate graft positioning, and decreased risk of neurovascular injuries. A Bankart capsulolabral repair is performed after graft fixation, making the graft extra-articular and providing additional stability.
