Project description:Abstract Background The Latarjet procedure is an effective technique for the treatment of recurrent anterior shoulder dislocation with glenoid bone loss. However, the inevitable destruction of the coracoacromial arch may result in humeral head translation. The aim of the study is to introduce a modified Latarjet technique with coracoacromial arch preservation as well as its short term clinical outcomes. Methods We propose a novel individualized flexible arthroscopic suture button fixation Latarjet technique called `LUtarjet' with video. Precise measurements of the coracoid process, glenoid deficiency and osteotomy plane were made preoperatively. Only three arthroscopic portals were needed and limit unique coracoid osteotomy was performed with coracoacromial arch preservation. The mini window splitting of the subscapularis was performed from the posterior to the anterior direction and the split window was as small as 8–10 mm in length. Results A total of 27 patients (25.6 ± 5.4 years) were included in the study. The average surgical duration was 55.6 ± 6.3 min and the mean follow-up time was 8.1 ± 1.5 months. The functional score was significantly improved at the last follow-up. Radiologic evidence showed that the bone graft healing was placed in the desired position. No complications were found. Conclusions We present a fast, easy, accurate, safe arthroscopic ‘LUtarjet’ technique called FEAST that can simplify the arthroscopic Latarjet process and achieve a satisfactory bone graft position and satisfactory short-term clinical outcomes. Level of evidence IV, case series.

Project description:The arthroscopic Latarjet procedure is challenging because it can be difficult to place 2 screws parallel to the glenoid surface and a medial portal (dangerous for the brachial plexus) is mandatory. In addition, precise positioning of the coracoid bone block flush with the joint line and in a subequatorial position as recommended is troublesome without the use of a guiding system because of the arthroscopic lens distortion. To improve the reproducibility of the arthroscopic Latarjet procedure and to minimize the risk of nerve complications, we developed a guiding system to optimize the positioning of the coracoid bone block and 2 cortical buttons to facilitate its fixation. Four portals are used: a posterior standard portal and 3 anterior portals, all lateral to the conjoint tendon. The anterior rim of the glenoid and the coracoid process are prepared. Two holes are drilled in the glenoid and in the coracoid process with 2 specific guides. The subscapularis is then split, and 2 cortical buttons are passed from posterior to anterior through the tunnels with a shuttle relay. The coracoid process undergoes osteotomy and is guided through the split in the subscapularis to the anteroinferior rim of the glenoid by pulling on the cortical buttons.

Project description:The Latarjet procedure is a method for treating complicated glenohumeral joint dislocation that is often associated with a bone defect in the anterior glenoid. The Latarjet procedure addresses both soft-tissue and bone deficiencies by creating a biceps tendon sling and through bone reconstruction of the anterior glenoid defect. The arthroscopic Latarjet procedure provides good visual control in the structures and eliminates the need for an arthrotomy. We present an arthroscopy-assisted Latarjet technique where the coracoid is temporarily exteriorized to facilitate shaping and preparation for subsequent fixation to the glenoid. Coracoid debridement, anterior glenoid preparation, and the subscapular split are conducted arthroscopically. Cutting the coracoid process is also conducted under arthroscopic control, and the coracoid is exposed through the anteroinferior portal. Once the coracoid is openly shaped and the drill-holes are made, the coracoid is resituated and fixed to the glenoid edge in arthroscopic visual control. The purpose of this technique is to combine favorable elements of the open and arthroscopic procedures. Additionally, the instrumentation is simple, which makes the operation safe and practical to perform.

Project description:Restoration of glenoid bony integrity is critical to minimizing the risk of recurrence and re-creating normal kinematics in the setting of anterior glenohumeral instability. We present an arthroscopic suture anchor-based technique for treating large bony Bankart fractures in which the fragment is secured to the intact glenoid using mattress sutures placed through the bony fragment and augmented with soft-tissue repair proximal and distal to the bony lesion. This straightforward technique has led to excellent fragment reduction and good outcomes in our experience.

Project description:PurposeTo measure bony morphologic parameters and identify their association with arthroscopic Bankart repair failure.MethodsThis was a retrospective comparative study. The inclusion criteria were primary arthroscopic Bankart repair, no prior shoulder surgery, traumatic cause, and had a Bankart (soft tissue and bony) lesion evident on magnetic resonance imaging (MRI). The exclusion criteria were posterior labral pathology, multidirectional instability, connective tissue disorder, rotator cuff pathology, and those who underwent concomitant shoulder procedures. Patients who had a postoperative redislocation (unstable group) were compared with matched patients who did not (stable group). Data were obtained by chart review and from preoperative MRI. Comparisons were made using the Student t test, Fisher exact test, or χ2 test. Statistical significance was defined as P < .05. Inter-rater reliability was measured between reviewers.ResultsA total of 45 patients experienced a postoperative dislocation and were matched to 90 patients without a postoperative dislocation. There were no differences in demographic and radiographic variables. The radius of curvature (ROC) of the glenoid was larger (shallower) in the unstable group (23.6 mm vs 22.6 mm, P = .05). The humeral head volume (HHV) trended higher in the unstable group (68.9 mL vs 62.9 mL, P = .06). The glenoid volume was not significantly different. A greater percentage of patients with a glenoid ROC of 24.5 mm or greater (62.1% vs 26.4%, P = .0003) and an HHV of 80 mm3 or greater (60.8% vs 28.9%, P = .003) experienced a redislocation compared with patients without these factors. Patients with a glenoid ROC of 24.5 mm or more and an HHV of 80 mm3 or more had greater than 4 times the odds of redislocation (odds ratio, 4.56; 95% confidence interval, 1.44-14.43; P = .0098). Strong inter-rater reliability was found for the HHV, glenoid volume, glenoid ROC, and humeral head ROC measurements (r = 0.94, r = 0.88, r = 0.89, and r = 0.95, respectively).ConclusionsThis study shows that large ROC (shallow) glenoids in conjunction with large humeral heads may predispose patients to failure after arthroscopic Bankart repair.Level of evidenceLevel III, retrospective comparative trial.

Project description:The arthroscopic treatment of the "bony Bankart lesion" continues to evolve. We present a novel technique that we developed at Orthopaedic Research of Virginia, the "transosseous bony Bankart repair," which incorporates several essential concepts to provide for optimal healing and rehabilitation. We promote arthroscopic repair emphasizing bone preservation, a fracture interface without interposing sutures, the ability to reduce capsular volume, and multiple points of stable glenolabral fixation. Our technique positions suture anchors within the subchondral bone of the intact glenoid to allow for an anatomic reduction of the bony fragment. By use of an arthroscopic drill, spinal needle, and nitinol suture passing wire, the sutures are passed in a retrograde fashion through the bony Bankart fragment and anterior capsule in a mattress configuration. Additional inferior and superior anchors are placed to further provide stability and reduce capsular volume. While maximizing fracture surface area and optimizing bony healing, the end result is an anatomic reduction of the bony fragment and the glenoid articular surface.

Project description:BackgroundThe present study investigated individualized coracoid osteotomy for 3D congruent arc glenoid reconstruction and evaluated the clinical outcomes in recurrent anterior shoulder dislocation.MethodsFrom January 2005 to July 2015, 78 patients with glenoid defect underwent coracoid and conjoint tendon transposition. The patients were divided into the individualized group (n = 34) and the non-individualized group (n = 44). All patients had CT data to reconstruct the shoulder model using Mimics software. In the individualized group, the individual coracoid osteotomy and bone fixation position parameters were measured from preoperative planification through simulating a 3D congruent arc glenoid reconstruction model. The non-individualized group underwent classic Bristow-Latarjet (B-L) procedure. The postoperative evaluation parameters included 3D congruent arc index, coracoid bone position, shoulder osteoarthritis index (Samilson-Prieto) and shoulder function score (Rowe, Constant-Murley score).ResultsThe mean follow-up time was 51.0 months (ranging from 24 to 146). The individualized group got 3D congruent arc reconstruction of the glenoid by postoperative CT scanning. Bone position was more precise in the individual group than that in the B-L group. There was a lower incidence of shoulder osteoarthritis (Samilson-Prieto) in the individual group compared with that in the B-L group: 0 vs 13.6% (mild 6/44, P = 0.027), respectively. No significant difference was observed between the individual and B-L groups in rate of re-dislocation: 0 vs 4.5% (2/44, P = 0.315), respectively. The postoperative Rowe and Constant score was significantly improved but was not significantly different between the two groups.ConclusionThe individual procedure achieved 3D congruent arc glenoid reconstruction. The clinical effects in patients with medium glenoid defect were good, especially the low incidence of shoulder osteoarthritis in middle-term follow-up.

Project description:Bony Bankart lesions of the anterior glenoid arise from traumatic glenohumeral instability events and can predispose persons to recurrent instability if not surgically stabilized. Large osseous fragments, when repaired anatomically, have excellent stability and functional outcomes; however, techniques to achieve this repair are often either tenuous or overcomplicated. In this technique guide, we describe a repair technique based on established biomechanical principles that achieves a reliable, anatomic glenoid articular surface. This technique can be readily applied in most bony Bankart settings using standard anterior labral repair instrumentation and implants.

Project description:The optimal management of anterior shoulder instability continues to be a challenge. The presence of an anterior glenoid rim fracture in the context of a glenohumeral dislocation, also called "bony Bankart lesion," can alter therapeutic behavior. Reduction and fixation of the bone fragment has been shown to greatly reduce the risk of recurrence once bone consolidation is achieved. However, there is no gold standard surgical technique. Stability of fixation and the healing of the bony fragment are still a concern, and there are no clinical studies comparing the different techniques to date. The aim of this report is to describe an arthroscopic double-point fragment fixation technique in lateral decubitus for the treatment of an acute traumatic shoulder dislocation with a bony Bankart lesion.

Project description:A bony Bankart lesion is an avulsion of the labroligamentous complex associated with an anterior glenoid rim fracture. Bony Bankart lesions can be seen in up to 70% of traumatic shoulder dislocations. With such a high prevalence, the development of an optimal repair technique is important. Selection of the most appropriate repair method depends heavily on the individual hard- and soft-tissue characteristics of the presenting lesion, as well as surgeon experience with the various repair options. We describe 3 arthroscopic Bankart fixation techniques (labrum alone, transosseous, and double row) to address a range of presenting Bankart pathologies.
