reverse total shoulder arthroplasty survivorship analysis of eighty replacements followed for five to ten years
Journal of Bone and Joint Surgery American Volume, 2006Co-Authors: Jacques Guery, Luc Favard, Francois Sirveaux, D Oudet, Daniel Mole, Gilles WalchAbstract:Background: Reverse total shoulder arthroplasty is currently being used to treat selected patients with disabling shoulder arthropathy. The purposes of this study were to investigate the medium-term results of reverse total shoulder arthroplasty and to analyze the influence of etiology on the result. Methods: We carried out a multicenter study with a minimum follow-up of five years and determined the survival rate of the prosthesis according to the initial etiology of the shoulder arthropathy. Eighty prostheses were implanted in seventy-seven patients between 1992 and 1998. Sixty-six shoulders had an arthropathy with a massive Rotator Cuff tear, and fourteen shoulders had a disorder with another etiology (rheumatoid arthritis, trauma, or revision arthropathy). At the time of review, eighteen patients had died and two were lost to follow-up. The remaining fifty-seven patients (sixty shoulders) were examined or interviewed by telephone at a mean follow-up of 69.6 months. Cumulative survival curves were generated with replacement of the prosthesis, glenoid loosening, and a functional Constant score of <30 as the end points. Results: The survival rate with replacement of the prosthesis and glenoid loosening as the end points were 91% and 84%, respectively, at 120 months, with shoulders that had arthropathy with a massive Rotator Cuff tear demonstrating a significantly better result than those that had a disorder with another etiology (p < 0.05). On the other hand, the survival rate with an absolute Constant score of <30 as an end point was 58% at 120 months, with no significant difference with respect to etiology. Two breaks were observed in the survival curves. The first concerned survival until replacement of the prosthesis and occurred at around three years, reflecting early loosening of the prosthesis. The curve then became stable. A second break started at around six years and reflected progressive deterioration of the functional result. Conclusions: Our findings indicate that the reverse total prosthesis should be reserved for the treatment of very disabling shoulder arthropathy with a massive Rotator Cuff Rupture, and it should be used exclusively in patients over seventy years old with low functional demands. Level of Evidence: Therapeutic Level IV. See Instructions to Authors for a complete description of levels of evidence.

anterior dislocation of the shoulder and Rotator Cuff Rupture
Clinical Orthopaedics and Related Research, 1993Co-Authors: Robert J Neviaser, Thomas J Neviaser, Jules S NeviaserAbstract:Thirty-seven patients older than 40 years of age were seen after sustaining primary anterior dislocations of the shoulder. An associated Rupture of the Rotator Cuff in each patient had been missed, often being mistaken for an axillary neuropathy. Eleven of these patients developed recurrent anterior instability that was due to Rupture of the subscapularis and anterior capsule from the lesser tuberosity. In no patient was there a Bankart lesion. Repair of the capsule and subscapularis restored stability in all of the patients with recurrence.

Traumatic injury of the axillary nerve identified after Rotator Cuff repair
'Asociacion Argentina de Ortopedia y Traumatologia', 2020Co-Authors: Cock Atehortua, Julián Guillermo, Restrepo Noriega, Victoria EugeniaAbstract:"La prevalencia del dolor de hombro oscila entre el 6,7% y el 66,7%; los trastornos del manguito rotador y especialmente la ruptura pueden alcanzar una prevalencia del 22,1%. Debido a los importantes avances y estudios en la reparación de esta lesión, la cirugía artroscópica ha permitido una mejor identificación, visualización y clasificación, y un mejor manejo de los pacientes. Además, la ruptura del manguito rotador o la fractura de la tuberosidad mayor del húmero incrementan el riesgo de lesión nerviosa (riesgo relativo –1,9), más significativa en pacientes >60 años. Se presenta a un paciente con ruptura postraumática del manguito rotador, quien requirió reparación artroscópica mínimamente invasiva, con evolución posoperatoria estacionaria y diagnóstico de lesión del nervio axilar, sin recuperación autolimitada atribuida a luxación anterior e inestabilidad secundaria al trauma inicial. Conclusiones: La lesión del nervio axilar es más frecuente que lo esperado y, en muchas ocasiones, la identificación temprana se pasa por alto debido a la alta asociación con otras lesiones. Por lo tanto, el diagnóstico y el manejo oportunos requieren mucho cuidado por parte del médico tratante.""The prevalence of shoulder pain varies between 6.7% and 66.7%; whereas Rotator Cuff disorders–especially Rupture–can reach a prevalence of 22.1%. Due to the important advances and studies in the repair of this injury, arthroscopic surgery has allowed a better identification, visualization and classification, as well as a better handling of the patients. In addition, Rotator Cuff Ruptures or greater tuberosity fractures increase the risk of nerve injury (relative risk -1.9), which is more significant in patients >60 years old. We discuss the case of a patient with post-traumatic Rotator Cuff Rupture who required minimally invasive arthroscopic repair. No weight-bearing was allowed during the postoperative period. Patient presented a non-self-limited axillary nerve injury secondary to anterior dislocation and resulting instability after the original trauma. Conclusions: Axillary nerve injuries are more common than expected and, in many cases, early identification is not possible due to its high rate of association with other injuries. Therefore, treating physicians must be very careful in order to achieve a timely diagnosis and management of the patient
