Epidemiology of Dupuytren disease and Patients Undergoing Selective Fasciectomy.

Objective To describe the epidemiological and clinical profile of patients with Dupuytren disease treated by selective fasciectomy and the factors associated with the severity of the disease. Methods Retrospective descriptive observational study involving 247 patients with Dupuytren disease, from 2013 to 2019. Multivariate logistic regression was performed for data analysis. Results Most patients were male (83.8%), self-declared white (65.2%), alcoholics (59.6%) and 49% were smokers, with a mean age of 66 ± 9 years old, with 77.2% presenting symptoms of the disease after the age of 51 years old. Approximately 51.9, 29.6 and 17.3%, respectively, had arterial hypertension, diabetes mellitus and dyslipidemia comorbidities. Bilateral involvement of the hands was observed in 73.3% of the patients. The rate of intra- and post-selective fasciectomy complications was of 0.6 and 24.3%, respectively, with 5.2% of the patients needing reintervention after 1 year of follow-up. After multivariate analysis, males were associated with bilateral involvement of the hands (odds ratio [OR] = 2.10; 95% confidence interval [CI]: 1.03-4.31) and with a greater number of affected rays (OR = 3.41; 95% CI: 1.66-7.03). Dyslipidemia was associated with reintervention (OR = 5.7; 95% CI = 1.03-31.4) and bilaterality with a higher number of complications (35.7 versus 19.7%). Conclusion A low rate of reintervention and operative complications was observed in patients with Dupuytren disease treated by selective fasciectomy. Male gender was associated with severe disease (bilaterality and more than two affected rays), and dyslipidemia with reintervention.

Intra-articular arthroscopic biceps tenodesis with interference screw: clinical and isokinetic evaluation.

BACKGROUND: Although biceps tenodesis has been widely used to treat its pathologies, few studies looked at the objective evaluation of elbow strength after this procedure. The purpose of this study is to clinically evaluate patients submitted to long head of the biceps (LHB) tenodesis with interference screws through an intra-articular approach and analyze the results of an isokinetic test to measure elbow flexion and forearm supination strengths. METHODS: Patients who had biceps tenodesis were included in the study if they had a minimum follow-up of 24 months. Patients were excluded if they had concomitant irreparable cuff tears or previous or current contralateral shoulder pain or weakness. Postoperative evaluation was based on University of California-Los Angeles (UCLA) shoulder score and on measurements of elbow flexion and supination strength, using an isokinetic dynamometer. Tests were conducted in both arms, with velocity set at 60º/s with 5 concentric-concentric repetitions. RESULTS: Thirty-three patients were included and the most common concomitant diagnosis were rotator cuff tear (69%) and superior labrum anterior to posterior (SLAP) lesions (28%). The average UCLA score improved from 15.1 preoperatively to 31.9 in the final follow-up (P < .001). Isokinetic tests showed no difference in peak torque between the upper limbs. One patient had residual pain in the biceps groove. None of the patients had Popeye deformity. UCLA score and follow-up length did not demonstrate correlation with peak torque. CONCLUSION: Arthroscopic proximal biceps tenodesis with interference screw, close to the articular margin, yielded good clinical results. Isokinetic tests revealed no difference to the contralateral side in peak torque for both supination and elbow flexion.

Arthroscopic Fixation of a Large Osteochondral Fragment From the Glenoid After First Episode Dislocation.

Osteochondral lesions of the glenoid are not so uncommon after traumatic cases of shoulder dislocation and can be a challenge to the shoulder surgeon because of the technical difficulty and the potential to progression to shoulder arthritis. An all-arthroscopic technique of fixation of a large osteochondral fragment is used to allow optimal visualization and reduction, minimize the morbidity of the open approach, and provide good functional results.

Proprioceptive deficit after total elbow arthroplasty: an observational study.

BACKGROUND: During total elbow arthroplasty (TEA), most of the joint capsule is removed, including many mechanoreceptors important for proprioception, which potentially limits the patient's postoperative functional recovery. We quantified proprioceptive loss by measuring the threshold to detection of passive motion (TTDPM) in patients after unilateral TEA compared with the contralateral side. METHODS: A continuous passive motion device moving the elbow at 0.5°/s was used to evaluate TTDPM in 8 patients (mean ± standard deviation age, 69.1 ± 9.93 years) at least 1 year after unilateral semiconstricted linked TEA for a range of diagnoses. Elbow function after TEA was assessed using the Mayo Elbow Performance Scale. RESULTS: Postsurgical Mayo scores revealed 4 excellent results, 2 good, and 2 poor. The TTDPM in the elbows undergoing arthroplasty was still significantly higher compared with the contralateral elbow at 4.2° (15.6 ± 6.9 seconds vs. 7.2 ± 2.6 seconds; D = 3.23, P = .01) equivalent to 8.4 seconds. CONCLUSIONS: Patients who have had severe joint disease requiring semiconstrained TEA have long-term proprioception deficits. A more conservative technique that maximally preserves insertions and soft tissues, might minimize upper limb proprioceptive deficit.

Strength training and shoulder proprioception.

CONTEXT: Proprioception is essential to motor control and joint stability during daily and sport activities. Recent studies demonstrated that athletes have better joint position sense (JPS) when compared with controls matched for age, suggesting that physical training could have an effect on proprioception. OBJECTIVE: To evaluate the result of an 8-week strength-training program on shoulder JPS and to verify whether using training intensities that are the same or divergent for the shoulder's dynamic-stabilizer muscles promote different effects on JPS. DESIGN: Randomized controlled clinical trial. SETTING: We evaluated JPS in a research laboratory and conducted training in a gymnasium. PATIENTS OR OTHER PARTICIPANTS: A total of 90 men, right handed and asymptomatic, with no history of any type of injury or shoulder instability. INTERVENTION(S): For 8 weeks, the participants performed the strength-training program 3 sessions per week. We used 4 exercises (bench press, lat pull down, shoulder press, and seated row), with 2 sets each. MAIN OUTCOME MEASURE(S): We measured shoulder JPS acuity by calculating the absolute error. RESULTS: We found an interaction between group and time. To examine the interaction, we conducted two 1-way analyses of variance comparing groups at each time. The groups did not differ at pretraining; however, a difference among groups was noted posttraining. CONCLUSIONS: Strength training using exercises at the same intensity produced an improvement in JPS compared with exercises of varying intensity, suggesting that the former resulted in improvements in the sensitivity of muscle spindles and, hence, better neuromuscular control in the shoulder.

Reverse arthroplasty of the shoulder for treating rotator cuff arthropathy / Artroplastia reversa do ombro no tratamento da artropatia do manguito rotador

OBJECTIVE: to present a retrospective analysis on the clinical-functional results and complications among patients with rotator cuff arthropathy (RCA) who underwent reverse arthroplasty of the shoulder. METHODS: patients with a diagnosis of RCA associated with pseudoparalysis of anterior elevation who underwent reverse arthroplasty of the shoulder with a minimum follow-up of one year were selected. RESULTS: preoperative information was gathered from our shoulder and elbow arthroplasty register, comprising age, sex, laterality, history of previous procedures, Constant's functional scores and the preoperative range of motion as described in the protocol of the American Academy of Shoulder and Elbow Surgery (ASES). After a mean follow-up of 44 months, 17 patients (94%) were satisfied with the result from the procedure. CONCLUSION: reverse arthroplasty for treating RCA in patients with pseudoparalysis of the shoulder was shown to be effective in achieving a statistically significant improvement in range of motion regarding anterior flexion and abduction. However, in this series, there was no improvement in range of motion regarding external and internal rotation. Reverse arthroplasty is a procedure that reestablishes shoulder joint function in patients who previously did not present any therapeutic possibilities...

Recurrent anterior glenohumeral instability: the quantification of glenoid bone loss using magnetic resonance imaging.

OBJECTIVE: To investigate the accuracy of conventional magnetic resonance imaging (MRI) in determining the severity of glenoid bone loss in patients with anterior shoulder dislocation by comparing the results with arthroscopic measurements. SUBJECTS AND METHODS: Institutional review board approval and written consent from all patients were obtained. Thirty-six consecutive patients (29 men, seven women; mean age, 34.5 [range, 18-55] years) with recurrent anterior shoulder dislocation (≥3 dislocations; mean, 37.9; range, 3-200) and suspected glenoid bone loss underwent shoulder MRI before arthroscopy (mean interval, 28.5 [range, 9-73] days). Assessments of glenoid bone loss by MRI (using the best-fit circle area method) and arthroscopy were compared. Inter- and intrareader reproducibility of MRI-derived measurements was evaluated using arthroscopy as a comparative standard. RESULTS: Glenoid bone loss was evident on MRI and during arthroscopy in all patients. Inter- and intrareader correlations of MRI-derived measurements were excellent (intraclass correlation coefficient = 0.80-0.82; r = 0.81-0.86). The first and second observers' measurements showed strong (r = 0.76) and moderate (r = 0.69) interreader correlation, respectively, with arthroscopic measurements. CONCLUSIONS: Conventional MRI can be used to measure glenoid bone loss, particularly when employed by an experienced musculoskeletal radiologist.

Evidence of genetic variations associated with rotator cuff disease.

BACKGROUND: Rotator cuff disease (RCD) is a complex process influenced by a multitude of factors, and a number of gene pathways are altered in rotator cuff tears. Polymorphisms in these genes can lead to an extended tendon degeneration process, which explains why subsets of patients are more susceptible to RCD. MATERIALS AND METHODS: Twenty-three single-nucleotide polymorphisms within 6 genes involved in repair and degenerative processes (DEFB1, DENND2C, ESRRB, FGF3, FGF10, and FGFR1) were investigated in 410 patients, 203 with a diagnosis of RCD and 207 presenting with absence of RCD. Exclusion criteria were patients older than 60 years and younger than 45 years with a history of trauma, rheumatoid arthritis, autoimmune syndrome, pregnancy, and use of corticosteroids. Genomic DNA was obtained from saliva samples. Genetic markers were genotyped with TaqMan real-time polymerase chain reaction. The χ(2) test compared genotypes and haplotype differences between groups. Multivariate logistic regression analyzed the significance of many covariates and the incidence of RCD. RESULTS: Statistical analysis revealed female sex (P = .001; odds ratio, 2.07 [1.30-3.30]) and being white (P = .002; odds ratio, 1.88 [1.21-2.90]) to be risk factors for RCD development. A significant association of haplotypes CCTTCCAG in ESRRB (P = .05), CGACG in FGF3 (P = .01), CC in DEFB1 (P = .03), and FGFR1 rs13317 (P = .02) with RCD could be observed. Also, association between FGF10 rs11750845 (P = .03) and rs1011814 (P = .01) was observed after adjustment by ethnic group and sex. CONCLUSIONS: Our work clearly supports the role of DEFB1, ESRRB, FGF3, FGF10, and FGFR1 genes in RCD. Identification of these variants can clarify causal pathways and provide a clue for therapeutic targets.

Electrophysiological correlates of the threshold to detection of passive motion: an investigation in professional volleyball athletes with and without atrophy of the infraspinatus muscle.

The goal of the present study is to compare the electrophysiological correlates of the threshold to detection of passive motion (TTDPM) among three groups: healthy individuals (control group), professional volleyball athletes with atrophy of the infraspinatus muscle on the dominant side, and athletes with no shoulder pathologies. More specifically, the study aims at assessing the effects of infraspinatus muscle atrophy on the cortical representation of the TTDPM. A proprioception testing device (PTD) was used to measure the TTDPM. The device passively moved the shoulder and participants were instructed to respond as soon as movement was detected (TTDPM) by pressing a button switch. Response latency was established as the delay between the stimulus (movement) and the response (button press). Electroencephalographic (EEG) and electromyographic (EMG) activities were recorded simultaneously. An analysis of variance (ANOVA) and subsequent post hoc tests indicated a significant difference in latency between the group of athletes without the atrophy when compared both to the group of athletes with the atrophy and to the control group. Furthermore, distinct patterns of cortical activity were observed in the three experimental groups. The results suggest that systematically trained motor abilities, as well as the atrophy of the infraspinatus muscle, change the cortical representation of the different stages of proprioceptive information processing and, ultimately, the cortical representation of the TTDPM.

Incidência de hemotransfusão na artroplastia total primária unilateral do joelho / Incidence of blood transfusion in primary unilateral total knee arthroplasty

Cento e doze joelhos de 105 pacientes foram submetidos à artroplastia total primária unilateral, utilizando-se três vias de acesso: subvasto, transquadricipital medial e transquadricipital lateral. Noventa e um pacientes (98 joelhos) tinham como doença de base a osteoartrose e 14 pacientes, artrite reumatóide. A incidên- cia de hemotransfusão nas cirurgias foi de 8 por cento. No grupo dos pacientes com osteoartrose e que não foram transfundidos, não houve diferença na variação do hematócrito devida à cirurgia, comparando-se estas variações nas três vias de acesso utilizadas. As doenças de base não exerceram influência sobre a incidência de hemotransfusão.

Acesso subvasto para astroplastia total do joelho / Subvastus approach to total knee arthroplasty

Os autores relatam sua experiência com o acesso subvasto em 63 artroplastias primárias do joelho, em pacientes sem desvio de eixo ou com deformidade em varo. Em apenas um paciente houve impossibilidade de adequada exposiçao articular. Consideram ser essa uma abordagem segura e ressaltam o fato de ser acesso mais anatômico que o transquadricipal, com possíveis vantagens vasculares e funcionais.
