OBJETIVO: Analisar os resultados do reparo artroscópico das rupturas do manguito rotador. MÉTODOS: Realizado estudo retrospectivo com avaliação dos resultados da técnica em 42 pacientes operados entre 2002 e 2006. O seguimento médio foi de 31 meses e a média de idade foi de 57 anos, sendo o lado dominante operado em 73,8% dos casos. Para avaliação foram usadas escalas de UCLA e Escala Visual Analógica da dor no pós-operatório. RESULTADOS: Os resultados foram satisfatórios em 85,7% (59,5% excelentes e 26,2% bons respectivamente) e insatisfatórios em 14,3% dos pacientes. Nos casos com lesões associadas, a mais frequente foi no tendão da porção longa do bíceps (57,1%). Associação com outras lesões não comprometeu o resultado. O mesmo aconteceu com relação a idade e tempo de acompanhamento pós-cirurgia. Quanto ao tamanho da lesão, diferença significativa ocorreu nos casos de lesões grandes e maciças demonstrando resultados inferiores em relação às pequenas e médias. A função foi inferior principalmente nos casos de lesão maciça. CONCLUSÃO: A reparação artroscópica das lesões do manguito rotador (MR) proporciona baixa morbidade cirúrgica e possibilita diagnóstico de lesões articulares associadas. O benefício do procedimento foi confirmado principalmente pela melhora significativa da dor, mesmo nos casos de lesões maiores.

The objective of this study was to assess the clinical benefits and financial feasibility of using ultrasound for steroid injections of the shoulder. A retrospective chart review and telephone survey of patients in a clinical shoulder practice were performed. ICD-9 codes and CPT codes identified patients who received shoulder injections without (2006) and with (2007) ultrasound guidance during 2 consecutive years. Results were assessed by patient assessment of relief and duration of that relief via telephone survey or from chart review. Financial data was assessed by reviewing the patients' accounts. One hundred fifty-seven injections were given in 2006 and 159 in 2007. In 2006, 126 unique patients were injected compared to 99 unique patients in 2007 (P<.001). Clinical data was collected on 272 patients (86.1%). Ultrasound had no significant effect on the amount of pain relief following injection (P=.468). One hundred thirty-six patients (50.0%) reported significant pain relief, 72 (26.5%) reported moderate, 39 (14.3%) reported mild, and 25 (9.2%) reported no pain relief following injection. During both years, 92.4% of patients had subacromial injections with no significant difference in injection sites (subacromial vs glenohumeral) between the 2 years (P=.252). Neither the injection site (subacromial or glenohumeral, P=.152) nor diagnosis (P=.540) had a significant effect on pain relief. Financial collections from injections increased as expected due to the use of ultrasound.Ultrasound guidance did not change the efficacy of steroid injections, the number of injections, or the type of injections. Steroid injections are useful for managing pain in several shoulder conditions and ultrasound guidance may not be necessary.

Shoulder fracture-dislocations are uncommon. Those associated with intrathoracic dislocation are very rare conditions, resulting from high-energy trauma; usually, the affected limb is in an abduction position. In Brazil, there is only one report of a teenager with displacement of the epiphysis into the chest cavity; the present is the first adult patient report of intrathoracic dislocation of the humerus. The authors present the case of a patient female, aged 56 years, who was hit by motorcycle and thrown approximately 5 meters away. She was rescued on site with thoracic, pelvic, and right upper limb trauma. Her chest was drained due to pneumothorax and multiple fractures of ribs; she was diagnosed with fracture-dislocation in four parts, with intrathoracic dislocation of the humeral head. Displaced forearm bones fracture was also diagnosed; the olecranon, scaphoid, and ischiopubic fractures were not displaced. The patient underwent a joint procedure with a cardiothoracic surgery team to remove the humeral head through thoracotomy and chest drainage; subsequently, a partial arthroplasty of the humerus was performed, with graft from the humeral head and fixation of forearm fractures. Conservative treatment was chosen for the other fractures. After three months, all fractures were healed with gradual functional improvement. The patient remained in physiotherapy and orthopedic monitoring, having been discharged from the thoracic surgery; in a severe depressive episode, the patient committed suicide after 11 months of the trauma.

Objective: The use of images in 3D reconstruction is an instrument that facilitates the interpretation of the fracture, observations of deviations, rotations and articular surface. Objective: To evaluate the inter-observer and intra-observer reliability of the Neer x AO proximal humerus fracture classification on radiographs versus computed tomography with three-dimensional reconstruction (3D). Methods: We evaluated the digital radiographs (anteroposterior and profile) and computerized tomography with 3D reconstruction of patients presenting with a proximal humerus fracture, surgically treated at an Orthopedics and Traumatology Service. All radiographs and computed tomography were classified (Neer and AO) by eight (8) orthopedic surgeons, specialists in the upper limb and sent, following the pre-established numeration by the author, in a spreadsheet to the author of the study. Results: The Neer and AO scores were more reproducible when determined by computed tomography with 3D reconstruction, mainly in fractures of greater complexity (Neer 4 parts and AO group C). However, in absolute values, inter and intra-observer reproducibility and concordance still remain low. Conclusion: Computed tomography with 3D reconstruction allows a better analysis of fractures of group C and Neer 4 parts. However, the inter and intra-observer agreement does not increase significantly in comparison to the radiographs. Level of evidence III, Study of non-consecutive patients, without gold standard, applied uniformly.

Objectiveto compare healing strength of the infraspinatus tendon of rats with corticoid inoculation, regarding maximum tension, maximum force and rupture force, after injury and experimental repair.Methodsa total of 60 Wistar rats were subjected to tenotomy of the infraspinatus tendon, which was then sutured. Before the surgery, they were divided into a control group (C) inoculated with serum and a study group (S) inoculated with corticoids over the tendon. After repair, the rats were sacrificed in groups of 10 individuals in the control group and 10 in the study group at the times of one week (C1 and S1), three weeks (C3 and S3) and five weeks (C5 and S5). The rats were dissected, separating out the infraspinatus tendon with the humerus. The study specimens were subjected to a traction test, with evaluation of the maximum tension (kgf/cm2), maximum force (kgf) and rupture force (kgf), comparing the study group with the respective control groups.Resultsamong the rats sacrificed one week after the procedure, we observed greater maximum tension in group C1 than in group S1. The variables of maximum force (kgf) and rupture force did not differ statistically between the groups investigated. In the same way, among the rats sacrificed three weeks after the procedure, group C3 only showed greater maximum tension than group S3 (p = 0.007), and the other variables did not present differences. Among the rats sacrificed five weeks after the procedure (C5 and S5), none of the parameters studied presented statistical differences.Conclusionwe concluded that corticoid diminished the resistance to maximum tension in the groups sacrificed one and three weeks after the procedure, in comparison with the respective control groups. The other parameters did not show differences between the study and control groups.
