    Abstract ABSTRACT Objective This study investigated the factors associated with satisfactory early postoperative wound conditions. Method A prospective study was conducted with patients (n=179) submitted to osteosynthesis in general, in a hospital orthopedics service. In the preoperative period, patients underwent laboratory exams and the surgical indications were based on the type of fracture and the patient’s clinical conditions. In the postoperative period, patients were evaluated based on the presence of complications and considering their surgical wounds. Chi-square, Fisher, Mann-Whitney, and Kruskal-Wallis tests were used in the analysis. To identify the factors associated with wound condition, univariate and multiple logistic regression analysis was used. Results In the univariate analysis, each transferring unit reduction increased the chance of satisfactory outcome by 1.1% (p=0.0306; OR= 0.989 (1.011); 95%CI= 0.978;0.999; 1.001;1.023). The presence of SAH increased 2.7 fold the chance of satisfactory outcome (p=0.0424; OR= 2,667; 95%CI= 1,034;6,877). Hip fracture increased 2.6 fold the chance of satisfactory outcome (p=0.0272; OR=2.593; IC95%=1.113; 6.039). And the absence of a compound fracture increased 5.5 fold the chance of satisfactory wound outcome (p=0.0004; OR=5,493; 95%CI=2,132;14,149). In the multiple analysis, patients with non compound fractures were 9.7 times more likely to experience a satisfactory outcome when compared to patients with compound fractures (p=0.0014; OR=9,687; 95%CI= 2,399; 39,125). Conclusion There was an inverse relationship between plasma proteins levels and satisfactory surgical wounds outcome. Only exposure remained associated with wound conditions. Level Of Evidence: II, Prospective Study.

    Abstract Background: Obesity is associated with nonalcoholic fatty liver disease (NAFLD), which is improved by bariatric surgery. Hepatobiliary scintigraphy with 99m.-Tc diisopropylacetanilido iminodiacetic acid (99mTc-DISIDA) has proved to be highly effective for the assessment of bile flow, representing an indirect measurement of hepatocyte and cholangiocyte function. The objective of this study was to assess the effects of Roux-en-Y gastric bypass (RYGB) on bile flow in obese subjects by hepatobiliary scintigraphy. This study was conducted in a public university hospital in Brazil.
    Methods: Twenty obese patients and five nonobese patients (with no hepatic or biliary disease) were studied. The obese patients were submitted to anthropometric evaluation and biochemical exams when they arrived at the service, during the immediate preoperative period and 3, 6, and 12 months after surgery. They were also submitted to abdominal ultrasound and hepatobiliary scintigraphy with 99mTc-DISIDA during the preoperative period and 12 months after RYGB. Tmax (time of maximum marker uptake) and T1/2 (half time between peak uptake and disappearance of the marker) were determined and compared between obese patients and controls, before and after surgery. The results were compared to those obtained with an intraoperative liver biopsy.
    Results: A weight loss of 12.2 ± 4.3 % was observed during preparation for surgery, and a loss of 30.4 ± 5.6 % was observed 1 year after RYGB. Ultrasound hepatic analysis revealed some degree of NAFLD in the operated patients. Obese patients showed a prolonged T1/2 compared to control, with a reduction to normal levels after RYGB.
    Conclusions: We concluded that NAFLD compromises bile excretion, a process that can be reversed by treatment with RYGB.

    Abstract ABSTRACT OBJECTIVE: To evaluate, compare and identify the surgical technique with best results for treating intra-articular calcaneal fractures, taking into account postoperative outcomes, complications and scoring in the Aofas questionnaire. METHODS: This was a retrospective study on 54 patients with fractures of the calcaneus who underwent surgery between 2002 and 2012 by means of the following techniques: (1) open reduction with extended L-shaped lateral incision and fixation with double-H plate of 3.5 mm; (2) open reduction with minimal incision lateral approach and percutaneous fixation with wires and screws; and (3) open reduction with minimal incision lateral approach and fixation with adjustable monoplanar external fixator. RESULTS: Patients treated using a lateral approach, with fixation using a plate had a mean Aofas score of 76 points; those treated through a minimal incision lateral approach with screw and wire fixation had a mean score of 71 points; and those treated through a minimal incision lateral approach with an external fixator had a mean score of 75 points. The three surgical techniques were shown to be effective for treating intra-articular calcaneal fractures, without any evidence that any of the techniques being superior. CONCLUSION: Intra-articular calcaneal fractures are complex and their treatment should be individualized based on patient characteristics, type of fracture and the surgeon's experience with the surgical technique chosen.

    Abstract ABSTRACT OBJECTIVE: To evaluate the clinical results from treating chronic peripheral nerve injuries using the superficial peroneal nerve as a graft donor source. METHODS: This was a study on eleven patients with peripheral nerve injuries in the upper limbs that were treated with grafts from the sensitive branch of the superficial peroneal nerve. The mean time interval between the dates of the injury and surgery was 93 days. The ulnar nerve was injured in eight cases and the median nerve in six. There were three cases of injury to both nerves. In the surgery, a longitudinal incision was made on the anterolateral face of the ankle, thus viewing the superficial peroneal nerve, which was located anteriorly to the extensor digitorum longus muscle. Proximally, the deep fascia between the extensor digitorum longus and the peroneal longus muscles was dissected. Next, the motor branch of the short peroneal muscle (one of the branches of the superficial peroneal nerve) was identified. The proximal limit of the sensitive branch was found at this point. RESULTS: The average space between the nerve stumps was 3.8 cm. The average length of the grafts was 16.44 cm. The number of segments used was two to four cables. In evaluating the recovery of sensitivity, 27.2% evolved to S2+, 54.5% to S3 and 18.1% to S3+. Regarding motor recovery, 72.7% presented grade 4 and 27.2% grade 3. There was no motor deficit in the donor area. A sensitive deficit in the lateral dorsal region of the ankle and the dorsal region of the foot was observed. None of the patients presented complaints in relation to walking. CONCLUSIONS: Use of the superficial peroneal nerve as a graft source for treating peripheral nerve injuries is safe and provides good clinical results similar to those from other nerve graft sources.

    Abstract <sec> OBJECTIVE: To validate a new method of measuring the Cobb angle for scoliosis from the mobile app CobbMeter to facilitate the evaluation and measurement in clinical practice. </sec><sec> METHODS: Five observers with minimum experience of two years in the field performed radiographic measurements of Cobb angle in 24 radiographs of patients with adolescent idiopathic scoliosis through the CobbMeter. Observers performed serial measures on the images with the application, which were repeated after one month. The most experienced appraiser of the group, after measurements were made through the application, determined the Cobb angle in each radiography by the traditional method. </sec><sec> RESULTS: The mean standard deviation by comparing the angles electronically and manually measured had no clinical significance. Although 40% of electronic measurements are outside the confidence interval when compared to manual measurements, this difference was insignificant in clinical practice. </sec><sec> CONCLUSIONS: The CobbMeter is another alternative for measuring Cobb angle in scoliosis. </sec>

    Abstract Abstract Objective To evaluate 15 patients with ruptured distal biceps tendon submitted to reinsertion via a single, anterior and transverse approach using two anchors. They were submitted to a rehabilitation protocol and, within six months, to an evaluation of the range of motion and strength intensity during flexion and supination of the operated elbow. Methods The data were collected prospectively, and were analyzed through the Mann-Whitney test and the mixed-model test to evaluate the force between the operated and non-operated elbows. Results A total of 80% of the patients were men, 60% were injured on the dominant side, 46% were manual workers, and 73% led sedentary lifestyles. The use of anabolic steroids was reported by two patients. After the treatment, the patients recovered supination strength by 98% and flexion by 94%. According to the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, 73% of the patients presented the score expected of a normal population. Conclusion The single, anterior and transverse approach associated with tendon repair using anchors was esthetically satisfactory, with good strength recovery during flexion and supination, and no occurrence of heterotopic ossification.

    Abstract ABSTRACT OBJECTIVES: Evaluate the functional grade of these patients and to identify the types of complications found that influenced the average life span of endoprostheses the functions of the operated limb. METHODS: We analyzed 14 post-operative cases of endoprosthesis, patients with malignant bone tumors and aggressive benign bone tumors submitted to surgery between 2004 and 2014. The evaluation system used was proposed by Enneking, recommended by the Musculoskeletal Tumor Society (MSTS), in addition to the radiologic evaluation. RESULTS: Endoprosthesis are excellent choices for the treatment of bone tumors with limb preservation in relation to pain, strength, and patient's emotional acceptance. Another factor for good results is the immediate weight-bearing capacity, generating a greater independence. CONCLUSION: The authors conclude that all patients classified the therapy as excellent/good, regardless of the type of prosthesis used, extent of injury, and/or type of tumor resection performed.

    Abstract Abstract Objective To demonstrate that the intraosseous (IO) access is more effective compared with the intravenous (IV) access for prophylactic antibiotic administration in knee joint surgeries, using 36 pigs as live models. Materials and Methods Skin, subcutaneous tissue, cartilage, and bone samples were collected, analyzed and compared after the administration of IV or IO antibiotic in different groups. Results When comparing the IO and IV groups, the IO group showed a higher concentration of prophylactic antibiotic in the skin (p = 0.049), cartilage (p = 0.018), and bone (p = 0.002), in the analysis of the first 24 hours after 30 minutes of infusion. Conclusion Since complications regarding this practice are rare, the use of this pathway may be an alternative to reduce the risk of surgical site infection in orthopedic surgeries, leading to a decrease in morbidity and mortality and hospital expenses with readmission or prolonged hospitalization time. However, further research and further experimental studies in humans are required, as the effectiveness of the method in pigs has been proved.
