Establishing minimal clinically important difference for the UCLA and ASES scores after rotator cuff repair.

BACKGROUND/HYPOTHESIS: Minimal clinically important difference (MCID) is a vital tool in the analysis of clinical results. It allows the determination of clinical relevance of statistical data. Our hypothesis was that specific differences between preoperative and postoperative scores would be able to accurately predict patient perception of improvement and satisfaction as reflected by anchor and distribution-based questions. METHODS: Retrospective cohort with patients that underwent rotator cuff repair. We evaluated the University of California at Los Angeles Shoulder Rating Scale (UCLA) and the American Shoulder and Elbow Surgeons Assessment Form (ASES) before and 12-months after surgery. Anchor-based, distribution-based and minimum detectable change (MDC) approaches were utilized. RESULTS: We evaluated 289 shoulders. The MCID for the UCLA scale was 4.5 points using the anchor method, 2.5 by the distribution method and 3.6 by MDC. Patients with a baseline score>20 presented a lower MCID (1.5, 1.1 and 1.7, respectively). For the ASES score, the MCID was 6.1 by the anchor method, 10.5 based on the distribution method and 26.3 by MDC. In the group of patients above the 60 point cutoff, the obtained values were 2.4, 4.9 and 13.6, respectively. CONCLUSION: The mean MCID value for the UCLA shoulder score is 3.5 points, ranging from 2.5 points (distribution method) to 4.5 points (anchor method). The mean MCID value for the ASES score was 15.2 points, ranging from 6.1 (anchor method) to 26.3 (MDC). Patients groups presenting with higher preoperative scores showed lower MCID values. This fact needs to be considered in postoperative comparisons between treatment groups. LEVEL OF EVIDENCE: Basic Science Study, Validation of Outcomes Instruments/Classification Systems.

Surgical Treatment of Post-traumatic Elbow Stiffness by Wide Posterior Approach.

Objective To demonstrate the clinical outcomes and complication rates of the surgical release with a single posterior approach in the treatment of post-traumatic elbow stiffness. Methods A prospective study with patients submitted to surgery between May 2013 and June 2018 in a single center. The access to the elbow was made through the posterior approach. The patients were followed up by an occupational therapy team, and were submitted to a standardized rehabilitation protocol, with static progressive orthoses and dynamic orthoses. The primary outcome was the range of flexion-extension of the elbow after 6 months. Results A total of 26 patients completed the minimum follow-up of 6-months. The mean range of flexion-extension of the elbow at the end of 6 months was of 98.3 ± 22.0°, with an amplitude gain of 40.0 ± 14.0° in relation to the pre-operative period ( p < 0.001). The average flexion-extension gain at the end of 6 months was of 51.7% ± 17.1% ( p < 0.001). The mean pronosupination at the end of 6 months was of 129.0 ± 42.7° ( p < 0.001). Half of the cases had moderate and severe stiffness in the pre-operative period, compared with 7.7% at 6 months post-operatively ( p < 0.001). The mean score for the Mayo Elbow Performance Score (MEPS) and Disabilities of the Arm, Shoulder and Hand (DASH) instruments was 74.4 ± 16.8 points and 31.7 ± 21.9 points respectively ( p < 0.001 for both). The visual analogue scale (VAS) score presented no statistically significant difference compared to the pre-operative period ( p = 0.096). Complications were observed in 6 (23%) patients, and no new surgical procedures were necessary. Conclusions The surgical release of the elbow associated with a rehabilitation protocol is a safe technique, with satisfactory results and low rate of complications.

Isokinetic evaluation of the shoulder and elbow after Latarjet procedure.

BACKGROUND/HYPOTHESIS: The Latarjet procedure changes the anatomy of the shoulder, moving the coracoid process distally through an incision in the subscapularis muscle. Some authors have studied the effect of this surgery on shoulder rotator strength. Our hypothesis is that the Latarjet procedure decreases elbow supination and flexion strength. METHODS: A retrospective case series, evaluating patients submitted to the Latarjet procedure between May 2013 and June 2017. Movements of the elbow (supination, pronation, flexion and extension) and shoulder (internal and external rotation) were evaluated bilaterally using a Biodex System 3 isokinetic dynamometer (Biodex Medical Systems, New York) in concentric/concentric mode. RESULTS: We evaluated 20 patients with an average follow-up of 36 months. In the elbow, we observed a 9.1% decrease in supination strength at a speed of 60°/s (p=0.044), without statistical difference at 120°/s (p=0.570). In the shoulder, there was a 13.5% decrease in external rotation strength at 60°/s and 4.5% at 180°/s (p=0.009 and p=0.040, respectively). The other movements did not demonstrate any statistically significant differences. CONCLUSION: After the Latarjet procedure, the supination strength at 60°/s was decreased, as was the external rotation strength of the shoulder at 60°/s and 180°/s. We did not observe any reduction in strength for shoulder flexion or internal shoulder rotation. LEVEL OF EVIDENCE: IV, case series.

Randomized trial for the treatment of post-traumatic elbow stiffness: surgical release vs. rehabilitation.

BACKGROUND: There are no previous randomized trials comparing surgical to conservative treatment for post-traumatic elbow stiffness. The aim of our study was to compare elbow range of motion (ROM) and clinical outcomes among patients undergoing surgical treatment or a standardized rehabilitation for post-traumatic elbow stiffness. METHODS: Randomized clinical trial of patients with post-traumatic elbow stiffness for more than 6 months who failed conventional physical therapy for 4 months. Patients were randomized into 2 treatment groups. The conservative group underwent the rehabilitation protocol associated with the use of orthoses (static progressive for extension and dynamic for flexion) and continuous passive motion. The surgical group underwent surgical release by a posterior approach without triceps detachment, followed by a rehabilitation protocol similar to the conservative group. The primary outcome of the study was flexion-extension ROM at 6 months of follow-up. Secondary outcomes included the visual analog scale for pain, the Mayo Elbow Performance Score, the Disabilities of the Arm, Shoulder, and Hand score, absolute and relative increase in flexion-extension ROM, and complication rates. RESULTS: Thirty patients were analyzed in the study, 15 in each group. The mean elbow flexion-extension ROM at the end of 6 months of follow-up was 108° in the surgical group and 88° in the conservative group (P = .002). The mean absolute and the relative increase of elbow flexion-extension at 6 months were, respectively, 17° and 27% in the conservative group and 41° and 59% in the surgical group (P < .001). CONCLUSION: Surgical elbow release associated with the rehabilitation protocol resulted in a greater flexion-extension ROM, as well as a greater absolute and relative increase compared with rehabilitation alone at 6 months of follow-up. The groups did not differ regarding clinical scores and complication rates.

Locking intramedullary nails versus locking plates for the treatment of proximal humerus fractures.

INTRODUCTION: Proximal humerus fractures (PHF) are common fractures and are the third most common type of fractures among older adults. The most commonly used implants include the locking plate and the locking intramedullary nail. Areas covered: The aim of this study is to perform a literature review of biomechanical and clinical studies that compare the locking plate and intramedullary nail for PHF osteosynthesis. Expert commentary: Twelve clinical studies and seven biomechanical studies were identified that met this criterion. The findings of this review showed that intramedullary nailing and locking plate fixation yielded similar functional results, but with contrasting complication rates. The biomechanical studies showed controversial results, with most of the studies demonstrating better biomechanical properties for the intramedullary nail. Different types of intramedullary nail for PHF have different characteristics, with curvilinear nails presenting a higher risk of complications.

Clinical outcomes of arthroscopic rotator cuff repair: correlation between the University of California, Los Angeles (UCLA) and American Shoulder and Elbow Surgeons (ASES) scores.

BACKGROUND: There are more than 40 outcome scores for evaluating shoulder pain and function. Some studies have correlated the results obtained using different scales, but none has compared the results obtained by the University of California, Los Angeles (UCLA) and American Shoulder and Elbow Surgeons (ASES) scores. METHODS: We performed a retrospective study to evaluate patients who underwent arthroscopic rotator cuff repair with 2 years' follow-up. The patients were evaluated by the UCLA and ASES scores preoperatively and at 6, 12, and 24 months after surgery. The Pearson correlation coefficient (r) was calculated to measure the degree of correlation between the 2 outcome scores. RESULTS: We evaluated 143 patients. At 24 months postoperatively, the UCLA and ASES scores were 30.4 ± 5.8 and 81.2 ± 20.8, respectively (P < .001). The UCLA and ASES scores showed a very high correlation (r = 0.91, P < .001). In all the postoperative clinical evaluations, the scores obtained from the 2 scales were highly or very highly correlated (r = 0.87-0.92, P < .001). For the preoperative scores, the correlation was moderate (r = 0.67, P < .001). CONCLUSION: The UCLA and ASES scores presented a very high correlation in the evaluation of surgical treatment of rotator cuff tear. In the preoperative period, the correlation was moderate.

Matrix Metalloproteases 1 and 3 Promoter Gene Polymorphism Is Associated With Rotator Cuff Tear.

BACKGROUND: Studies suggest that the collagen degeneration and disordered arrangement of collagen fibers in rotator cuff tears are associated with an increase in activity of matrix metalloproteases 1 and 3 (MMP-1 and MMP-3), and that MMP activity may be in part genetically mediated. The degree to which this might be clinically relevant in patients with rotator cuff tears has not been well characterized. QUESTIONS/PURPOSES: (1) Is genetic polymorphism of MMP-1 and MMP-3 associated with rotator cuff tears? (2) Are there haplotypes of MMP-1 and MMP-3 correlated with rotator cuff tears? (3) Compared with control subjects, do patients with rotator cuff tears have a higher proportion of relatives with the same disease? METHODS: We evaluated 64 patients with full-thickness rotator cuff tears and 64 asymptomatic control subjects. Patients younger 65 years, with nontraumatic tears, were included. The tear or integrity of the rotator cuff tear was evaluated by MRI or ultrasonography in all individuals. The patients and control subjects were paired by age. MMP-1 and MMP-3 genotypes were determined using the PCR-restriction fragment length polymorphism assays. RESULTS: Genetic polymorphisms in MMP-1 and MMP-3 are associated with rotator cuff tear, in which individuals with rotator cuff tears have associated genotypes 1G/2G (patients, 32 of 64 [50%], control subjects, 16 of 64 [25%]; odds ratio [OR], 4.8; 95% CI, 2.1-11.0; p < 0.001) and 2G/2G were at great risk (patients, 15 of 64 [23%], control subjects, seven of 64 [11%]; OR, 5.2; 95% CI,1.8-14.9; p < 0.001), and patients with rotator cuff tears were associated with a higher proportion of 2G allele distribution (62 of 128 [48%] versus 30 of 128 [23%]; p < 0.001). Patients with the 5A/5A genotype are at greater risk of rotator cuff tear (patients, 15 of 64 [23%]; control subjects, four of 64 [6%]; OR, 5.5; 95% CI, 1.4-20.9; p = 0.021), and there was higher 5A allele distribution in patients with rotator cuff tears (patients, 68 of 128 [53%]; control subjects, 52 of 128 [41%]; p = 0.045). Individuals with the haplotype 2G/5A were more likely to have rotator cuff tears develop (patients, 42 of 64 [66%]; control subjects, 17 of 64 [27%]; OR, 5.3; 95% CI, 2.5-11.3; p < 0.001). Patients with rotator cuff tears reported, in higher number, the existence of relatives who previously had treatment for rotator cuff tears (19 of 64 [30%] versus four of 64 [6%]; OR, 6.3; 95% CI, 2.0-19.9; p = 0.001). CONCLUSIONS: The genetic polymorphism of MMP-1 and MMP-3 is associated with rotator cuff tear. Individuals with haplotype 2G/5A were more susceptible to rotator cuff tears in the population studied. CLINICAL RELEVANCE: Knowledge of the genetic markers related to rotator cuff tears can enable identification of susceptible individuals and increase understanding of the pathogenesis of tendon degeneration.

Intraobserver and interobserver agreement in the classification and treatment of proximal humeral fractures.

BACKGROUND: There is controversy surrounding the reliability of radiographic measurements and existing classifications for proximal humeral fractures. METHODS: Ten orthopedists, divided into 2 groups by length of experience, evaluated radiographs in 3 views from 40 proximal humeral fractures. We evaluated 11 radiographic criteria (including the Neer and pathomorphologic classifications, head-shaft angle, displacement of the humeral shaft, and lesser and greater tuberosities) and treatment indication. We also analyzed the criteria that most influenced the choice of treatment. RESULTS: Interobserver reliability was substantial for the presence of fracture of the greater tuberosity (κ = 0.749) and medial metaphyseal comminution (κ = 0.627) and moderate for the pathomorphologic classification (κ = 0.504), displacement of the greater tuberosity (κ = 0.422), and treatment decision (κ = 0.565). Intraobserver reliability was substantial for treatment indication (κ = 0.620) and presence of displacement of the fracture of the greater tuberosity (κ = 0.627 and 0.611) and moderate for the Neer (κ = 0.490) and pathomorphologic (κ = 0.607) classifications. The results were influenced by the observer's experience. The surgical indication was influenced by the pathomorphologic classification in 50% of the evaluators (odds ratio, 4.85; range, 3.30-8.65). CONCLUSION: The pathomorphologic classification has higher reliability than the Neer classification and was the factor that most influenced the surgical decision. The determination of the presence of fracture and displacement of the greater tuberosity and medial metaphyseal comminution is reliable with the use of simple radiographs, and the results were influenced by the observer's experience.

Fracture of the clavicle and second rib: an indirect injury from tricep dips.

Due to the recent rise in the interest in strength training, an increment in the number of lesions is expected, whether of the tendons, muscles, or bones. We describe a case of fracture involving the middle third of the clavicle and the second rib in a low-demand weightlifter. The fractures occurred suddenly while performing a triceps dips exercise, and the patient had no previous symptoms. He was treated conservatively and was able to return to sports six months later. To our knowledge, this is the first study describing the association of these fractures triggered by a single event of muscle contraction.

Accuracy of preoperative MRI in the diagnosis of subscapularis tears.

INTRODUCTION: The subscapularis has received little attention in the orthopedic literature, although such lesions are evident in up to 40 % of arthroscopies. An accurate diagnosis is important in clinical practice, as it affects both patient prognosis and surgical planning. The aim of this study was to evaluate the accuracy of preoperative MRI for the identification of subscapularis tears. Our secondary aim involved the identification of factors that may be predictive for the presence of subscapularis tears. MATERIALS AND METHODS: This retrospective case series included patients undergoing shoulder arthroscopy due to rotator cuff injury. MRI was performed using a 1.5 T unit, and the results were assessed by a musculoskeletal radiologist. The findings were compared to those of arthroscopic inspection. RESULTS: A total of 93 shoulders were analyzed. The overall accuracy was 82 %, with values of 79 % for partial tears and 89 % for full-thickness tears. Tears requiring repair demonstrated an accuracy of 88 %. Infraspinatus tears, fatty degeneration of the subscapularis, biceps instability and age were identified as predictive factors for the presence of injury. CONCLUSIONS: MRI of the shoulder demonstrated an accuracy of 82 % for the diagnosis of subscapularis tears. The accuracy values for partial and full-thickness tears were 79 and 89 %, respectively. LEVEL DE EVIDENCE: III, development of diagnostic criteria with universally applied reference-nonconsecutive patients.

Locking intramedullary nails compared with locking plates for two- and three-part proximal humeral surgical neck fractures: a randomized controlled trial.

BACKGROUND: Previous studies have shown good clinical results in patients with proximal humeral fractures (PHFs) treated with locking intramedullary nails or locking plates. Our study compared the clinical and radiographic outcomes in patients with 2- and 3-part surgical neck fractures. METHODS: In this prospective, randomized controlled trial, 72 patients with 2- or 3-part surgical neck PHFs were randomly assigned to receive fixation with locking intramedullary nails (nail group) or locking plates (plate group). The primary outcome was the 12-month Constant-Murley score. The secondary outcomes included the Disabilities of the Arm, Shoulder and Hand score, the visual analog scale pain score, the shoulder passive range of motion, the neck-shaft angle, and complication rates. RESULTS: There was no significant mean treatment group difference in the Constant-Murley score at 12 months (70.3 points for the nail group vs. 71.5 points for the plate group; P = .750) or at individual follow-up assessments. There were no differences in the 3-, 6- and 12-month Disabilities of the Arm, Shoulder and Hand scores, visual analog scale scores, and range of motion, except for the medial rotation at 6 months. The neck-shaft angle was equivalent between the groups at 12 months. There were significant differences over 12 months in total complication rates (P = .002) and reoperation rates (P = .041). There were no significant differences for the rotator cuff tear rate (P = .672). CONCLUSION: Fixation of PHFs with locking plates or locking intramedullary nails produces similar clinical and radiologic results. Nevertheless, the complication and reoperation rates were higher in the nail group.

The rotation of the humeral head does not alter radiographic evaluation of the head-shaft angle.

BACKGROUND: The head-shaft angle is used to plan osteotomies and arthroplasties and to assess the radiographic outcomes of surgical treatment for proximal humerus fractures. There are no published data showing whether different degrees of arm rotation interfere with the evaluation of this angle. METHODS: Eighteen humeri from adult cadavers were used. Radiographs were taken with the specimens initially placed in a true anteroposterior position and then subsequently positioned with internal and external rotations of 10°, 20°, and 30°. All radiographs were evaluated by 3 shoulder and elbow surgeons at 2 different times 3 months apart. The head-shaft angle was measured using a picture archiving and communication system. RESULTS: For the humerus in the neutral position, the head-shaft angle was 137° ± 4°. With the anatomic specimen positioned with increasing external and internal rotations, there was a maximum difference of 2° compared with the value observed in the neutral position, which was not a significant difference (P = .911). Measurements of the head-shaft angle showed a good interobserver correlation coefficient, with a value of 0.788 (0.728-0.839) for all measurements. The intraobserver correlation coefficient ranged from moderate to excellent (0.536-0.938). CONCLUSION: The head-shaft angle did not change significantly with varying degrees of humeral rotation. The interobserver correlation coefficient showed good reliability, and the intraobserver correlation was moderate to excellent.

Accuracy of preoperative MRI in the diagnosis of disorders of the long head of the biceps tendon.

OBJETIVES: To evaluate the accuracy of magnetic resonance imaging (MRI) in the detection of disorders of the long head of the biceps tendon (LHBT). The secondary objective was to investigate predictive factors for tears and instability. METHODS: This retrospective case series involved patients undergoing shoulder arthroscopy due to rotator cuff injury. MRI was performed in a 1.5T scanner and was evaluated by a musculoskeletal radiologist. The findings were compared with those of arthroscopic inspection. RESULTS: A total of 90 shoulders were analyzed. Regarding tears, there was 67% sensitivity and 98% specificity. Regarding instabilities, the values were 53% and 72%, respectively. Tears and fatty degeneration of the infraspinatus are predictive factors for tears of the LHBT. Tears of the subscapularis and infraspinatus, retraction of the supraspinatus and infraspinatus equal to or greater than 30mm, and fatty degeneration of the infraspinatus and subscapularis are predictive factors for instability. CONCLUSION: Compared to arthroscopy, the shoulder MRI has a sensitivity of 67% and a specificity of 98% for the detection of complete tears of the LHBT. For instability, the values are 53% and 72%, respectively.

Hypertension in employees of a University General Hospital.

PURPOSE: To find out the prevalence of hypertension in employees of the Hospital and relate it to social demographic variables. METHODS: Blood pressure measurement was performed with a mercury sphygmomanometer, using an appropriate cuff size for arm circumference, weight, and height in a population sample of 864 individuals out of the 9,905 employees of a University General Hospital stratified by gender, age, and job position. RESULTS: Hypertension prevalence was 26% (62% of these reported being aware of their hypertension and 38% were unaware but had systolic/diastolic blood pressures of >140 and/or >90 mm Hg at the moment of the measurement). Of those who were aware of having hypertension, 51% were found to be hypertensive at the moment of the measurement. The prevalence was found to be 17%, 23%, and 29% (P <.05) in physicians, nursing staff, and "others", respectively. The univariate analysis showed a significant odds ratio for the male gender, age >50 years, work unit being the Institute of Radiology and the Administration Building, educational level 10 years, and body mass index >30 kg/m2. The multivariate logistic regression model revealed a statistically significant association of hypertension with the following variables: gender, age, skin color, family income, and body mass index. CONCLUSIONS: Hypertension prevalence was high, mainly in those who were not physicians or members of the nursing staff. High-risk groups (obese, non-white, men, low family income) should be better advised of prevention and early diagnosis of hypertension by means of special programs.

OBJETIVO: Conhecer a prevalência de hipertensão arterial em funcionários de um complexo hospitalar e relacionar com variáveis sócio demográficas. MÉTODOS: Foi medida a pressão arterial com aparelho de coluna de mercúrio e manguito adequado à circunferência do braço, o peso e a altura em amostra de 864 dos 9.905 funcionários do Hospital Universitário estratificada de acordo com sexo, idade e ocupação. RESULTADOS: A prevalência de hipertensão foi de 26% (hipertensão referida = 62% ou pressão sistólica > 140 e/ou > 90 mm Hg no momento da medida = 38%). Dos que referiram 51% estavam hipertensos no momento da medida. A prevalência foi 17, 23 e 29% (p < 0,05) nos médicos, enfermagem e "outros". Análise univariada mostrou "odds ratio" significante para o sexo masculino, idade > 50 anos, unidade de trabalho para o Instituto de Radiologia e Prédio da Administração, escolaridade 10 anos e índice de massa corporal (IMC) maior ou igual a 30 kg/m2. O modelo de regressão logística com procedimento "stepwise" mostrou associação estatisticamente significante com hipertensão arterial para as variáveis: sexo, idade, cor da pele, renda familiar e IMC. CONCLUSÃO: A prevalência de hipertensão foi alta em funcionários do Complexo Hospital das Clínicas, principalmente nos de ocupação diferente de médico e enfermagem. Os grupos de maior risco (homens, cor preta, baixa renda familiar, obesos) precisam ser orientados quanto a prevenção e diagnóstico precoce da doença através de programas especiais.
