title: ANALYSIS OF FATTY DEGENERATION OF THE TRAPEZIUS MUSCLE AFTER USE OF ACCESSORY NERVE

description: ABSTRACT Objective: To investigate, through magnetic resonance imaging, the occurrence of fatty degeneration of the trapezius in adult patients undergoing nerve transfer procedure, using the spinal accessory nerve. Methods: A total of 13 patients meeting the criteria of unilateral brachial plexus injury and more than one year of postoperative care after nerve transfer surgery underwent an MRI scan of the trapezius. A T1-weighted 3D sequence was used, with the IDEAL technique using 8.0 mm cut thickness, 8.0 mm cut spacing, TR of 100 ms, TE of 3.45 ms, flip angle of 10 degrees, 20 cuts, on the sagittal plane. The images of the upper, transverse and lower parts of the trapezius muscle were then classified according to the degree of fatty degeneration, compared with the contralateral side, using the Goutallier score. Results: For the upper trapezius there was a change of the degeneration state in 23% (p = 0.083), for the transverse section there was a change in 84.6% (p = 0.003), for the lower one there was a change in 92.3% (p = 0.002). Conclusion: The upper trapezius did not undergo significant degeneration after transfer. The lower and transverse trapezius suffered fatty degeneration in most patients, indicating severe functional impairment. Level of Evidence IV, Case series.

title: RANDOMIZED CONTROLLED TRIAL OF LIMITED FASCIECTOMY WITH INJECTION OF ADIPOSE GRAFT FOR DUPUYTREN’S DISEASE

description: ABSTRACT Objective: Dupuytren’s disease is a genetic disorder related to the proliferation of myofibroblasts. The pluripotent property of stem cells present in adipose tissue inhibits myofibroblast proliferation. Our study sought to evaluate the effect of stem cell-rich fat grafts in patients that underwent limited fasciectomy. Methods: We studied 45 patients, in a single-blind, prospective, randomized clinical trial. All patients underwent limited fasciectomy. In one group, fat graft was injected. Results: The total passive extension deficit results did not exhibit a significant difference. Fat group exhibited worse functional score at 6 months and 1 year postoperatively, such as higher complication rates (43%), when compared with control group (8%), and more pain at 6 weeks follow-up. Conclusion: Fat grafting associated with limited fasciectomy promotes worse functional results compared to conventional limited fasciectomy in the short term. However, long-term results and recurrence rates should be further assessed. Level of Evidence II, Prospective comparative study.

title: INTER- AND INTRA-OBSERVER RELIABILITY OF SCHATZKER, AO, AND LUO CLASSIFICATIONS FOR TIBIAL PLATEAU FRACTURES

description: ABSTRACT Objective: To verify inter- and intra-observer agreement of three classification systems for tibial plateau fractures - Schatzker, AO/ASIF, and Luo’s - among orthopedic surgery residents. Methods: This cross-sectional study was conducted with 29 observers. Radiographic and tomographic imaging of the knee of 15 patients presenting with fractures were evaluated. After six weeks, the test was reapplied. The level of agreement was calculated by the Kappa index. Results: In test 1, inter-observer agreement of all residents, according to the Kappa index, for Schatzker classification was 0.226, for AO 0.431, and Luo’s 0.319. In test 2, values were 0.316, 0.333, and 0.347, respectively (p &lt; 0.001). Regarding intra-observer analysis, the mean Kappa indexes of 1st-year residents were: Schatzker, 0.20; AO, 0.32; and Luo’s, 0.3. For 2nd-year residents, means were: 0.51, 0.58, and 0.38, respectively. As for 3rd-year, results were 0.42, 0.42, and 0.41, respectively (p &lt; 0.001). Conclusion: AO/ASIF showed a better reproducibility than other classifications, with substantial inter- and intra-observer agreement. We also found a stronger agreement among 2nd- and 3rd-year residents. Level of Evidence III, Diagnostic Studies - Investigating a Diagnostic Test.

title: HEMIEPIPHYSIODESIS USING EIGHT-PLATE VERSUS BLOUNT STAPLE TO CORRECT GENU VALGUM AND GENU VARUM

description: ABSTRACT Objective: Our objective is to evaluate whether the use of guided growth with eight-plates is more effective than the use of Blount staples for the correction of the idiopathic genu varum or idiopathic genu valgum. Methods: A systematic review (SR) was carried out according to the appropriate methodology for randomized clinical trials (RCTs). We searched seven databases through a previously defined methodology, and we included RCTs, regardless of language, period of publication and status of publication. Results: Resulted in 6830 articles retrieved. Of theses, we identified 14 potential eligible studies. but just one RCT was included for the SR. The included RCT compares the eight-plate and the Blount staple and showed no statistically significant difference for the outcomes of time to correct the deformity, postoperative pain after 24 hours and postoperative pain after 72 hours. The study is of low or very low level of evidence to determine the most effective technique. We didn’t find a RCT that compared the correction of the genu varum. Conclusion: Good quality randomized clinical trials comparing Blount staples versus eight-plaque must be performed to determine which technique is superior for coronal plane corrections. Level of Evidence I, Systematic review of Level RCTs.

title: ORTHOPEDIC RELATED COMORBIDITIES IN SPINAL CORD-INJURED INDIVIDUALS

description: ABSTRACT Objective: This study aims to review, identify and study the determinations of the main orthopedic aspects in SCI patients. Methods: A total of 80 articles from PUBMED and three theses (MSc. /DSc.) were examined. Results: The results refer to the most essential joints. There is a chronic overload on the shoulder girdle due to the use of the upper limb as a supporting joint. The elbow presents osteoarthritis, subclinical, acute and chronic pain, mainly in quadriplegic patients. In the hand and wrist joints there are cases of paralysis, osteoporosis and osteoarthritis. Hips are the main weight-bearing joints while sitting which leads to a substantial degenerative process of this joint. Lastly, on the knee, feet and ankles, spasticity, contractures, osteoporosis and deformities can arise. Conclusion: Along with the increase in cases and research that analyze the alterations that spinal cord-injured individuals suffer, it is necessary to recognize the orthopedic changes to understand their limits and identify the relevance of the rehabilitation program to improve the muscle performance.

title: CHANGES IN BONE MINERAL DENSITY AFTER TOTAL KNEE ARTHROPLASTY

description: ABSTRACT Objective: We aimed to investigate the change in bone mineral density (BMD) in the first postoperative year in patients that underwent total knee arthroplasty (TKA) due to primary osteoarthritis of the knee. Methods: Preoperative and first postoperative year dual-energy X-ray absorptiometry measurements of 76 patients with knee osteoarthritis, who undergone surgery between 2016 and 2018 due to the recommendation for TKA, were statistically evaluated in the study. Results: Of the 19 patients with a normal BMD in the preoperative period, 73.7% (n = 14) continued to have a normal BMD in the postoperative period. Of the 34 patients with a low BMD (osteopenia) in the preoperative period, 91.2% (n = 31) did not show any change, whereas osteoporosis was observed in two patients (5.9%) in the postoperative period. Of the 23 patients with osteoporosis in the preoperative period, 95.7% (n = 22) did not show any change, whereas osteopenia was observed in one patient (4.3%) in the postoperative period. Both the T and Z scores of the spine (L1-L4) and proximal femur showed a slightly positive trend, however, with an insignificant statistical difference (p ≥ 0.05). Conclusion: Patients that underwent TKA experienced a statistically insignificant bone gain at the spine and proximal femur twelve months after the surgery.

title: ELASTOGRAPHIC ANALYSIS OF THE SUPRASPINATUS TENDON IN DIFFERENT AGE GROUPS

description: ABSTRACT Objective: To compare the mechanical properties of the supraspinatus tendon in different age groups using Supersonic Shearwave Imaging (SSI) elastography. Methods: We evaluated 38 healthy individuals of both genders, 20 being in the range of 20 to 35 years and 18 being over 60 years. The shear modulus of the supraspinatus tendon was measured by SSI elastography, always on the right side. Means between age groups were compared and statistically analyzed using the Shapiro-Wilk normality test followed by the student’s t-test and were established as a statistically significant value of p ≤ 0.05. Results: A statistically significant difference was observed when the mean values of the shear modulus of the supraspinatus tendon of young adults (23.98 ± 9.94 KpA) were compared with those of older adults (17.92 ± 6.17 KpA). Conclusion: We found a difference between the means of the shear modulus measured by the SSI elastography, showing a significant decrease of the shear modulus with the chronological age progression.

title: RELATIONSHIP BETWEEN THE KNEE AND HINDFOOT AXES IN PATIENTS WITH SEVERE KNEE OSTEOARTHRITIS

description: ABSTRACT Objective: To evaluate the correlation between knee axis and hindfoot axis in patients with advanced gonarthrosis, and the association between ankle function and angular deformities. Methods: 72 patients were enrolled in the study: 66% were women, and mean age was 58.7 years. The anatomical axis of the knee and hindfoot were measured by short knee radiographs and long axial view of the hindfoot. Results: Among the study group, 79.2% presented varus knee (mean 15º ± 7.69º) and 20.8% valgus (mean 15.9º ± 7.7º). 63.9% had hindfoot varus (mean 8.5º ± 6.07º) and 36.1% valgus (mean 3.9º ± 3.92º) (p &lt; 0.05). The mean value for the American Orthopaedic Foot and Ankle Society (AOFAS) score was 74.26 points, and values were significantly higher among patients with hindfoot varus (p &lt; 0.05). We found no correlation between gender or AOFAS score and knee and hindfoot axes, nor between deformities in the knee and hindfoot axes (p &gt; 0.05). The subgroup genu valgum - hindfoot varus presented a moderate correlation (r = 0.564; p &lt; 0.05). Conclusion: We found no association between the anatomical axes of the knee and hindfoot. Patients with gonarthrosis and hindfoot varus presented a better ankle function.

title: UNICOMPARTIMENTAL KNEE ARTHROPLASTY - 15 YEARS FOLLOW UP

description: ABSTRACT Objective: To evaluate clinically and radiologically the long-term follow-up of patients with anteromedial osteoarthritis who underwent unicompartmental knee arthroplasty surgery. Methods: This study included 36 patients who underwent unicompartmental knee arthroplasty surgery for medial compartmental osteoarthritis with a minimum of 15-year post-operative follow-up. All surgeries were performed by a single surgeon (G.L.C) using the Miller-Galante unicompartmental knee implant. Patients were analyzed regarding their clinical functional and implant radiographic conditions. Results: From the 46 patients who could have completed 15 years of follow-up, three required revision surgery with conversion to total knee arthroplasty (6.5%), 36 completed the 15-year follow-up period, and the others were lost to follow-up for reasons not related to unicompartmental arthroplasty. Conclusion: In these 36 patients, the result was satisfactory after follow-up, with complaints and sign of progression of osteoarthritis in some cases. Level of Evidence IV, Case series.

title: QUALITY OF LIFE IN ADULTS WITH SARCOMAS UNDER CONSERVATIVE SURGERY OR AMPUTATION

description: ABSTRACT Objective: To understand the perception of quality of life, functionality, and psychological aspects of adults with lower limb sarcoma who underwent conservative surgery or amputation. Methods: Sociodemographic data were collected, and the following questionnaires were used: EORTC QLQ - C30 for quality of life, the Functional Assessment System (MSTS) for functionality and the Beck Depression Inventory (BDI) for depression symptoms. Results: The sample consisted of 45 young adults with sarcoma, divided into two groups: amputation (29) and conservative surgery (16). Most were male, single and students. Average family income before and after the disease did not differ, but those that were employed had a better perception of general quality of life, as well as those with higher family income after the disease. Regarding the type of surgery, there was a predominance of amputation; osteosarcoma was the most common histological type and the most affected region was the femur. All participants participated in social, cultural, sporting or religious activities. MSTS and Beck scale values did not differ between procedures. Conclusion: Given the scarcity of studies on the subject at the national level, further investigations are suggested to explore aspects related to quality of life for patients with sarcomas.
