Clinical Outcomes and Graft Resorption After Metal-Free Bone Block Suture Tape Cerclage Fixation for Recurrent Anterior Shoulder Instability: A Computed Tomography Analysis.

BACKGROUND: Glenoid reconstruction with a bone block for anterior glenoid bone loss (GBL) has shown excellent outcomes. However, fixation techniques that require metal implants are associated with metal-related complications and bone graft resorption. HYPOTHESIS: Arthroscopic glenoid reconstruction using a tricortical iliac crest bone graft (ICBG) and metal-free suture tape cerclage fixation can safely and effectively restore the glenoid surface area in patients with recurrent anterior shoulder instability and anterior GBL. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Adult patients (≥18 years) of both sexes with recurrent anterior shoulder instability and anterior GBL ≥15% were enrolled. These patients underwent arthroscopic glenoid reconstruction with ICBGs and metal-free suture tape cerclage fixation. The effectiveness and clinical outcomes with this technique were evaluated at 24 months using functional scores. Resorption of the graft articular surface was assessed by computed tomography, with the graft surface divided into 6 square areas aligned in 2 columns. Descriptive analysis was conducted. RESULTS: A total of 23 consecutive patients met inclusion criteria (22 male, 1 female; mean age, 30.5 ± 7.9 years). The mean preoperative GBL was 19.7% ± 3.4%, and there were 15 allograft and 8 autograft ICBGs. All patients exhibited graft union at 3 months. The median follow-up was 38.5 months (interquartile range, 24-45 months). The Western Ontario Shoulder Instability Index, Rowe, Constant-Murley, and Subjective Shoulder Value scores improved from preoperatively (35.1%, 24.8, 83.1, and 30.9, respectively) to postoperatively (84.7%, 91.1, 96.0, and 90.9, respectively) (P < .001). No differences in clinical scores were observed between the graft types. One surgical wound infection was reported, and 2 patients (8.7% [95% CI, 2.4%-26.8%]) required a reoperation. The mean overall glenoid surface area increased from 80.3% ± 3.5% to 117.0% ± 8.3% immediately after surgery before subsequently reducing to 98.7% ± 6.2% and 95.0% ± 5.7% at 12 and 24 months, respectively (P < .001). The mean graft resorption rate was 18.1% ± 7.9% in the inner column and 80.3% ± 22.4% in the outer column. Additionally, 3 patients treated with an allograft (20.0% [95% CI, 7.1%-45.2%]), including the 2 with clinical failures, exhibited complete graft resorption at the last follow-up. CONCLUSION: Arthroscopic glenoid reconstruction using an ICBG and metal-free suture tape cerclage fixation was safe and effective, yielding excellent clinical outcomes. Resorption of the graft articular surface predominantly affected the nonloaded areas beyond the best-fit circle perimeter.

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 all-arthroscopic 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.

Treatment of Symptomatic Medial Clavicle Nonunion with Intramedullary Tendon Allograft: A Case Report.

CASE: A 67-year-old patient sustained a medial clavicle fracture (MCF) treated with open reduction and fixation with cerclage sutures. A year later, he presented with symptomatic nonunion and skin prominence, which was revised with an intramedullary tendon allograft fixation including the sternoclavicular joint. At 31 months after the procedure, the patient showed no pain or clinical instability. CONCLUSION: MCF is an uncommon injury. Symptomatic nonunion after the failure of fixation is rarely described. Although the best way to treat this complication is debatable, revision fixation using an intramedullary tendon allograft can be a viable option in elderly patients.

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.

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°, 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.

Correlación entre hallazgos clínicos, de resonancia magnética y artroscópicos en el diagnóstico de rupturas meniscales / Relationship between clinical, MRI, and arthroscopic findings in meniscal tears

Objetivo: Evaluar y comparar la sensibilidad, especificidad, valor predictivo positivo, valor predictivo negativo y exactitud global de la exploración física y la resonancia magnética en el diagnóstico de rupturas meniscales, considerando los hallazgos artroscópicos como estándar de oro.Materiales y métodos: Se realizó un estudio de tipo prueba diagnóstica comparando la exploración física por un especialista y los hallazgos de resonancia magnética para el diagnóstico de lesiones meniscales en 140 pacientes, tomando como estándar de oro la artroscopia diagnóstica.Resultados: La exploración física tuvo una mayor especificidad que la resonancia magnética, con diferencia entre exploración física y resonancia magnética de 87.5% vs 42.4% y de 82.2% vs 33.3% en pruebas diagnósticas para menisco lateral y medial, respectivamente. Así mismo, se encontró una exactitud global mayor, con 82.2% vs. 63.3% para menisco lateral y 84.4% vs. 70% para menisco medial.Conclusión: La resonancia magnética en la presencia de una sospecha clínica alta de lesión de menisco es, en algunos casos, innecesaria para el diagnóstico de lesiones de menisco, y se debe reservar para ocasiones en las que los hallazgos clínicos no son concluyentes.Tipo de estudio: Prueba diagnóstica. Nivel de evidencia: II
