Objective  This study aims to evaluate and correlate the nutritional status with potential complications during the immediate postoperative period of elderly patients surgically treated for proximal femoral fractures. Methods  A prospective, cross-sectional analytical study with a quantitative approach, targeting patients aged 60 years old or more who were admitted to a hospital in Amazonas, Brazil, for surgical treatment of proximal femoral fractures. Surgical complications during the immediate postoperative period and their relationship with the nutritional status of the patient were determined using the mini nutritional assessment (MNA); in addition, the lymphocyte numbers and serum albumin levels were determined and correlated with the length of hospital stay. Results  The sample consisted of 19 elderly patients, of both genders, with a mean age of 70.8 years. Most of the subjects (68.4%) were female. Malnutrition was diagnosed in 15.8% of the subjects using the body mass index (BMI) as, an anthropometric variable, and the MNA identified 31.6% of the subjects with malnutrition. Regarding total lymphocyte count, 100% of the sample showed a positive association with malnutrition in varying degrees; using serum albumin level as a parameter, malnutrition was identified in 89.4% of the subjects. Malnourished patients had the highest average length of stay. Surgical complications as surgical site infections occurred in 10.5% of the patients at risk of malnutrition. Conclusion  This study revealed a higher rate of postoperative complications in elderly patients diagnosed with malnutrition.Objectives  The present study evaluates and compares the surgical treatment of acute and chronic acromioclavicular dislocations (ACDs) to define the most effective therapeutic plan. Methods  A retrospective study consisting of 30 patients submitted to the surgical treatment of types III and V ACDs between 2011 and 2018; the subjects were separated according to a temporal classification in acute ( 3 weeks; subgroup II) subgroups. All patients underwent a postsurgical evaluation with a standardized protocol containing epidemiological, functional, and radiological data. Results  Subgroup I presented a visual analog scale (VAS) score of 1.10, a Constant-Murley score of 92.3, and a University of California at Los Angeles (UCLA) Shoulder Rating score of 33.5. The coracoclavicular (CC) distance was of 11.0 mm, and the average increase in CC space was lower than 8.9% compared to the contralateral shoulder. In subgroup II, the VAS score was of 1.11, the Constant-Murley score was of 94.2, and the UCLA score was of 32.4. The CC distance was of 13.8 mm, with a 22.9% increase in CC space compared to the contralateral side. Conclusion  Although there was no significant difference between the evaluated items, subgroup I tended to present a lower CC distance ( p  = 0.098) and a lower percentage increase in CC distance ( p  = 0.095) compared to subgroup II. Thus, the surgical treatment must be performed within three weeks after the trauma to try to avoid such trend. If the acute treatment is not possible, the modified Weaver Dunn technique has good clinical and functional outcomes.Objective  To analyze long-term functional and radiographic results of partial shoulder replacement for humeral head osteonecrosis. Methods  Retrospective review of thirteen cases, with a mean postoperative follow-up of 17 years (range 10 to 26 years). The findings from the last follow-up were compared to those in which the patients had one year of postoperative follow-up. Functional assessment consisted of shoulder movement measurements and application of the University of California, Los Angeles (UCLA) shoulder score. All patients underwent radiographic examination to measure glenoid erosion, proximal humeral migration and lateral glenohumeral dislocation. Results  Glenoid erosion increased over time significantly ( p   less then  0.05). Paradoxically, all active shoulder movements also improved ( p   less then  0.05), while UCLA scores remained the same. Radiographic deterioration was not correlated with clinical function. We had an 84.7% survival rate for arthroplasties after a mean time of 16 years. Conclusions  Early functional outcomes were maintained in the long run and do not correlate with radiographic deterioration (increased erosion of the glenoid).Objective  To describe a new presentation of tears and retears of the rotator cuff, which we denominate captured rotator cuff (CRC). We also aim to evaluate it clinically and through images. Methods  We assessed retrospectively 16 patients with intraoperative diagnosis of CRC between March 2005 and September 2017; by means of imaging (radiography and magnetic resonance imaging [MRI]) and functional scores (UCLA and Constant & Murley). this website In images we analyzed the evolution for rotator cuff arthropathy and presence of retears. Functionally, we compared the affected side with the contralateral side and extensive lesions with nonextensive. Results  Five (31.25%) patients presented with rotator cuff arthropathy, and 10 (62.5%) with retears. Three (75%) patients with nonextensive lesions had good/excellent UCLA and Constant & Murley scores. In patients with extensive lesions, when the Constant & Murley score was evaluated, 6 (50%) presented good/excellent results, and in the UCLA score, 7 (58.3%). Comparing the affected side (Constant 74.72 points; UCLA 20 points) with the contralateral side (Constant 96.96 points; UCLA 25.63 points), there were worse functional results with statistical significance. Conclusion  The diagnosis of CRC is suspected by characteristic findings on MRI and confirmed in arthroscopy. The affected shoulders present worse functional postoperative scores.Objective  To evaluate the feasibility of magnetic resonance imaging (MRI) to obtain the critical shoulder angle (CSA) comparing the results obtained through radiography and MRI, and assess the learning curves. Methods  In total, 15 patients were evaluated in a blinded and randomized way. The CSA was measured and compared among groups and subgroups. Results  The mean angles measured through the radiographic images were of 34.61 ± 0.67 and the mean angles obtained through the MRI scans were of 33.85 ± 0.53 ( p  = 0.29). No significant differences have been found among the groups. The linear regression presented a progressive learning curve among the subgroups, from fellow in shoulder surgery to shoulder specialist and radiologist. Conclusion  There was no statistically significant difference in the X-rays and MRI assessments. The MRI seems to have its efficacy associated with more experienced evaluators. Data dispersion was smaller for the MRI data regardless of the experience of the evaluator.
