Técnica de reparación de manguito rotador tipo “Rip-Stop”. Se utiliza en tendones con bajo potencial de cicatrización y rupturas masivas del manguito rotador. Mejora la biomecánica de la reparación tratando de evitar su ruptura posterior a la reparación inicial.

Rotator Cuff Ripstop:
The load-sharing rip-stop uses 2 medial ⚓️ and 1 rip-stop tape independently secured with 2 lateral ⚓️. It improves ultimate LTC by 1.7x vs single-row and shows 53% healing of large/ massive tears vs 11% healing w single-row.

El tratamiento de las rupturas del ligamento cruzado anterior(LCA) en la rodilla sigue avanzando. En este caso se realizó una reconstrucción del LCA utilizando injertos de isquiotibiales(hamstrings) del propio paciente, con augmentacion con internal brace(Arthrex, Naples, FL). Este internal brace actúa como un cinturón de seguridad que mantiene el injerto estable en su etapa crítica de revascularización y remodelación cuando es más susceptible de romperse. Foto 1: se observa ya el injerto con dos Fibertapes o internal brace en el mismo sistema. Vídeo 1: se observa la entrada del injerto al túnel femoral y el acodamiento del internal brace. Vídeo 2: se observa ya como el internal brace se tensa y se termina de subir el injerto biológico de hamstring. Fotos 2 y 3: apariencia radiológica en el postop inmediato.

Did you know that you do NOT need an MRI to diagnose a frozen shoulder? The tried and true history and physical exam (and sometimes an X-ray) are usually enough.

Rotator Cuff Repair: When does it clinically benefit the patient?

In this month's Journal of Shoulder and Elbow Surgery, large tear size, prior shoulder surgery, and to***co use were associated with failure to achieve a minimum clinically important difference.

Sabemos que la causa más frecuente de una escapula alada es la parálisis del serrato anterior por una lesión mecánica del nervio torácico largo. El tratamiento es complejo y la neurólisis del nervio parece ser una estrategia apropiada en casos específicos en donde el tratamiento conservador ha fallado.

Es un honor. La investigación científica es crítica para mejorar la calidad de atención de nuestros pacientes.

An understanding of the "humeroscapular motion interface” is critical to understanding common shoulder problems such as impingement, posterior capsule contracture, subacromial bursitis, and post-traumatic shoulder stiffness. Our current understanding can be attributed most recently to the shoulder surgeons at the University of Washington. EA Codman emphasized the coracoacromial ligament as “having an important duty” as part of this normal shoulder articulation. https://pubmed.ncbi.nlm.nih.gov/9602810/

La hiperlipidemia se relaciona con una mala cicatrización en la interfase hueso-tendón y con una progresión de la infiltración grasa después de una reparación del manguito rotador. Sin embargo, el uso de estatinas para control de la hiperlipidemia normalizan la cicatrización del manguito rotador.

Background
Hyperlipidemia is linked to poor tendon-to-bone healing and progression of fatty infiltration after rotator cuff repair. Statins effectively treat hyperlipidemia, but it is unknown if they have any potential detrimental effects following rotator cuff repair. The aim of this study was to evaluate the effect of statins on rotator cuff healing and fatty infiltration following repair.
Methods
A total of 77 patients undergoing arthroscopic rotator cuff repair were recruited prospectively, 38 patients who were prescribed a statin for hyperlipidemia (statin group) and 39 patients who were not taking a statin (control group). Patients who did not have both preoperative and 1-year postoperative magnetic resonance imaging (MRI) scans were excluded from the study. Patient-reported outcome measures, namely the Western Ontario Rotator Cuff (WORC) index, Constant-Murley score, American Shoulder and Elbow Surgeons (ASES) score, and Disabilities of the Arm, Shoulder and Hand (DASH) score, were collected preoperatively and at 1 year. Fatty infiltration was assessed on MRI according to the Goutallier grade preoperatively and at 12 months; rotator cuff healing was assessed at 12 months according to the Sugaya classification. Following propensity score weighting to adjust for baseline imbalances, 12-month outcomes were compared between the 2 groups.
Results
At 12 months, all patient-reported outcome measures had improved significantly compared with baseline (WORC score, 85.9 vs. 32.5, P < .001; ASES score, 87.3 vs. 37.5, P < .001; Constant-Murley score, 77 vs. 31, P < .001; and DASH score, 13.6 vs. 61.4, P < .001). There was no significant difference in postoperative scores in the statin group vs. the control group (WORC score, 84.9 vs. 89.6, P = .94; ASES score, 87.5 vs. 86.6, P = .40; Constant-Murley score, 77 vs. 81, P = .90; and DASH score, 14.4 vs. 11.4, P = .14), and for 3 of these scores, the 95% confidence intervals excluded a clinically meaningful difference. Similarly, rotator cuff healing at 12 months and Goutallier fatty infiltration grades were comparable between the 2 groups. Retears were seen in 6 patients (15.8%) in the statin group and 8 (20.5%) in the control group. Progression of fatty infiltration was seen in 4 patients (10.5%) in the statin and 4 (10.3%) in the control group. Statin use did not demonstrate a significant association with either retear risk (P = .41) or progression of fatty atrophy (P = .69).
Conclusion
Patient-reported outcomes, rotator cuff retear rate, and fatty infiltration on MRI at 12 months after rotator cuff repair in patients with hyperlipidemia treated with statins are similar to those in a control group.

In 1974, pitcher Tommy John sustained what was thought to be a career ending elbow ligament tear. After MUCL reconstruction by Dr. Frank Jobe, he returned to play from 1977-89 achieving 288 career wins.
