[Ti] Título: High Survivorship and Few Complications With Cementless Total Wrist Arthroplasty at a Mean Followup of 9 Years. [So] Source: Clin Orthop Relat Res;475(12):3082-3087, 2017 Dec. [Is] ISSN: 1528-1132 [Cp] País de publicação: United States [La] Idioma: eng [Ab] Resumo: BACKGROUND: Total wrist arthroplasty (TWA) has been described as traditionally being performed with fixation in the radius and carpus with cement. The TWA implant used in our series has been associated with promising results in studies with up to 6 years followup; however, studies evaluating survivorship, pain, and function with this implant are limited. QUESTION/PURPOSE: (1) To report ROM and pain scores after wrist reconstruction with cementless fourth-generation TWA at a mean followup of 9 years (range, 4.8-14.7 years). (2) To report complications of a cementless fourth-generation TWA and the cumulative probability of not undergoing a revision at a mean followup of 9 years. METHODS: This is a retrospective case series of 69 patients who were treated for pancarpal wrist arthritis between 2002 and 2014. Of those, 31 had inflammatory arthritis (rheumatoid arthritis [n = 29], juvenile rheumatoid arthritis [n = 1], and psoriatic arthritis [n = 1]); all of these patients received TWA with the cementless implant studied in this investigation. Another 38 patients had osteoarthritis or posttraumatic arthritis; in this subgroup, 28 patients were 65 years or younger, and all underwent wrist fusion (none were offered TWA). Ten patients with osteoarthritis were older than 65 years and all were offered TWA; of those, eight underwent TWA, and two declined the procedure and instead preferred and underwent total wrist arthrodesis. The mean age of the 39 patients who had TWA was 56 ± 8.9 years (range, 31-78 years) at the time of surgery; 36 were women and three were men. The patients who underwent TWA were seen at a minimum of 4 years (mean, 9 years; range, 4-15 years), and all had been examined in 2016 as part of this study except for one patient who died 9 years after surgery. The dominant wrist was involved in 60% (25) of the patients. All patients were immobilized for 4 weeks postoperatively and then underwent hand therapy for 4 to 6 weeks. Pain and ROM were gathered before surgery as part of clinical care, and were measured again at latest followup; at latest followup, radiographs were analyzed (by the senior author) for evidence of loosening, defined as any implant migration compared with any previous radiograph with evidence of periimplant osteolysis and bone resorption. Subjective pain score was assessed by a verbal pain scale (0-10) and ROM was measured with a goniometer. Complications were determined by chart review and final examination. Kaplan Meier survival analysis was performed to estimate the cumulative probability of not undergoing a revision. RESULTS: The mean preoperative active ROM was 34 ± 18° flexion and 36° ± 18° extension. Postoperatively, the mean active ROM was 37° ± 14° flexion and 29° ± 13° extension. The mean difference between the preoperative pain score (8.6 ± 1.2) and postoperative pain score (0.4 ± 0.8) was 8.1 ± 1.9 (p < 0.001). Implant loosening occurred in three (7.7%) patients. No other complications occurred in this series. Kaplan-Meier survivorship analysis estimated the cumulative probability of remaining free from revision as 78% (95% CI, 62%-91%) at 15 years. CONCLUSION: Cementless fourth-generation TWA improves pain while generally preserving the preoperative arc of motion. The cumulative probability of remaining free from revision at 14.7 years after the index procedure is 77.7% (95% CI, 62.0%-91.4%). Future studies should compare alternative approaches for patients with endstage wrist arthritis; such evaluations-which might compare TWA implants, or TWAs with arthrodesis-will almost certainly need to be multicenter, as the problem is relatively uncommon. LEVEL OF EVIDENCE: Level IV, therapeutic study.

[Ti] Título: Clinical outcomes of anterior cruciate ligament reconstruction using LARS artificial graft with an at least 7-year follow-up. [So] Source: Medicine (Baltimore);96(14):e6568, 2017 Apr. [Is] ISSN: 1536-5964 [Cp] País de publicação: United States [La] Idioma: eng [Ab] Resumo: The aim of our study was to assess the medium-term clinical outcomes of anterior cruciate ligament (ACL) reconstruction using the Ligament Advanced Reinforcement System (LARS) artificial ligament.A total of 168 patients who underwent arthroscopic ACL reconstruction with the LARS artificial ligament in our department were enrolled in our research. Only 125 met the inclusion/exclusion criteria, and 91 could ultimately be contacted to participate in our research. The mean follow-up was 92 ±â€Š19 months. Physical examinations and a KT-1000 arthrometer were used to evaluate knee laxity. The International Knee Documentation Committee (IKDC) and Lysholm knee scales were evaluated for knee function. The Tegner score was tested for the condition of return to sport. Range of motion (ROM) and the rates of failure and complications were calculated.Among all patients enrolled in the study, the failure rate was 4.4%, and the overall complication rate was 2.2%. Knee laxity measured by the KT-1000 arthrometer was 1.4 ±â€Š1.5 mm, compared with the preoperative value of 5.1 ±â€Š1.3 mm. The Lysholm score improved from a preoperative value of 54.6 ±â€Š14.3 to a postoperative value of 85.4 ±â€Š12.1. The proportion of return to sport was 86.8% (79/91). The postoperative Tegner score was 4.7 ±â€Š1.3, while its value before injury was 5.5 ±â€Š1.0.In this study, ACL reconstruction using the LARS artificial ligament has a good prognosis with a low failure and complication rate at a mean follow-up of 91 months.

[Ti] Título: Digital data acquisition of shoulder range of motion and arm motion smoothness using Kinect v2. [So] Source: J Shoulder Elbow Surg;26(5):895-901, 2017 May. [Is] ISSN: 1532-6500 [Cp] País de publicação: United States [La] Idioma: eng [Ab] Resumo: BACKGROUND: Range of motion (ROM) is a clinically important parameter in evaluating joint function. However, dynamic evaluation to determine the quality of the arm motion using digitized measurement is often overlooked during clinical assessment. We evaluated the accuracy of Kinect v2 (Microsoft, Redmond, WA, USA) as a digital tool for measuring shoulder ROM objectively and proposed a concept of motion smoothness reflecting the quality of arm motion. METHODS: Ten male participants were included in a 2-stage experiment. First, shoulder ROM was measured in 4 static poses (flexion, abduction, external rotation, and internal rotation) with Kinect v2, a 3-dimensional (3D) motion analysis system, and goniometry. Second, participants performed a point-to-point arm motion as naturally as possible. Kinematic data were collected with Kinect v2 and the 3D motion analysis system and then postprocessed to acquire parameters related to motion smoothness, including peak to mean velocity ratio, acceleration to movement time ratio, and number of peaks. RESULTS: Kinect v2 resulted in very good agreement of ROM measurement (r > 0.9) with the 3D motion analysis (95% limits of agreement < ±8°) compared with goniometry (95% limits of agreement < ±10°). Kinect v2 also showed a good correlation and agreement of measurement of motion quality parameters compared with the 3D motion analysis (peak to mean velocity ratio, acceleration to movement time ratio, and number of peaks: r = 0.769, discrepancy = ±0.1; r = 0.922, discrepancy = ±5%; and mean = 1 ± 0, respectively). CONCLUSIONS: We show that Kinect v2 can be used as a reliable tool to measure shoulder ROM and arm motion smoothness.

[Is] ISSN: 1872-8464 [Cp] País de publicação: Ireland [La] Idioma: eng [Ab] Resumo: INTRODUCTION: Head movements are controlled by the vestibular system. Children with sensorineural hearing loss can present restrictions in ampleness of head movements due to damage in the vestibule-cochlear systems, resulting from injury in the inner ear. OBJECTIVE: To evaluate the ampleness of head movements of children with normal hearing and children with sensorineural hearing loss and compare data between groups. METHODS: Cross-sectional study that evaluated the ampleness of head movements of 96 students, being 48 with normal hearing and 48 with sensorineural hearing loss, of both sexes, with aged between 7 and 18 years old. The performance of ampleness of head movements was analyzed by a manual goniometric evaluation, according the references proposed by Marques. To the statistical analysis we used the t-Student test in case of normality of the data or the Mann-Whitney test when did not applied the suppositions of normality. RESULTS: Hearing loss children showed less mean in ampleness of all movements of head compared to normal hearing children, pointing difference to movements of flexion (p = 0,001), lateral inclination to the right (p = 0,025) and lateral rotation to the left (p = 0,021). CONCLUSION: Hearing loss children showed reduction in the ampleness of these head movements: flexion, lateral inclination to the right and lateral rotation to the left compared to normal hearing children.

[Ti] Título: Reliability of Visual Estimation of the First Intermetatarsal Angle. [So] Source: J Foot Ankle Surg;56(1):8-9, 2017 Jan - Feb. [Is] ISSN: 1542-2224 [Cp] País de publicação: United States [La] Idioma: eng [Ab] Resumo: The size of the radiographic first intermetatarsal (IM) angle is one of the main considerations in selecting a surgical procedure for hallux abducto valgus. Instead of directly measuring the IM angle with a goniometer or a virtual measurement system, physicians will often estimate the size of the IM angle by direct visual estimation. The purpose of the present study was to determine the accuracy of visual estimation of the IM angle size compared with direct measurement. A total of 45 respondents, composed of students, residents, and attending physicians, reviewed a series of radiographs with IM angles varying from 6° to 19°. The attending physician visual estimates differed from the measured values by 3.28° ± 1.56°. The interrater reliability, as determined by the intraclass correlation (ICC), increased with experience by group category: 0.426 (95% confidence interval 0.239 to 0.672) for students, 0.476 (95% confidence interval 0.290 to 0.710) for residents, and 0.656 (95% confidence interval 0.483 to 0.833) for attending physicians. Larger IM angles, defined as >10° were less accurately estimated than were smaller IM angles (3.96° ± 1.60° [n = 24] for larger IM angles and 3.14° ± 0.79° [n = 21] for smaller IM angles; p = .0389). These results suggest caution when visually estimating IM angles, especially larger IM angles. Direct angle measurement might be more appropriate for surgical decision-making.

[So] Source: IEEE Trans Neural Syst Rehabil Eng;25(9):1409-1418, 2017 Sep. [Is] ISSN: 1558-0210 [Cp] País de publicação: United States [La] Idioma: eng [Ab] Resumo: An approach to finger motion capture that places fewer restrictions on the usage environment and actions of the user is an important research topic in biomechanics and human-computer interaction. We proposed a system that electrically detects finger motion from the associated deformation of the wrist and estimates the finger joint angles using multiple regression models. A wrist-mounted sensing device with 16 electrodes detects deformation of the wrist from changes in electrical contact resistance at the skin. In this study, we experimentally investigated the accuracy of finger joint angle estimation, the adequacy of two multiple regression models, and the resolution of the estimation of total finger joint angles. In experiments, both the finger joint angles and the system output voltage were recorded as subjects performed flexion/extension of the fingers. These data were used for calibration using the least-squares method. The system was found to be capable of estimating the total finger joint angle with a root-mean-square error of 29-34 degrees. A multiple regression model with a second-order polynomial basis function was shown to be suitable for the estimation of all total finger joint angles, but not those of the thumb.

[Is] ISSN: 1433-7347 [Cp] País de publicação: Germany [La] Idioma: eng [Ab] Resumo: PURPOSE: To inventory the examination methods available to assess antero-medial rotational laxity (AMRL) of the knee following medial collateral ligament injury. METHODS: Searches were conducted in accordance with the PRISMA guidelines and using four online databases: WEB OF SCIENCE, MEDLINE, EMBASE, and AMED. The Critical Appraisal Skills Programme guidelines for Diagnostic Test Studies were used for the quality assessment of the articles. RESULTS: A total of 2241 articles were identified from the database searches. From this, four articles were included in the final review. All were case-control studies, considered a combined ACL/MCL injury and had small study populations. Specialised equipment was required in all studies, and one needed additional imaging support before measurements could be taken. Two employed commercially available measuring equipment as part of the assessment process. CONCLUSION: Clinical assessment of AMRL in relation to a MCL injury remains challenging. Although methods have been developed to support clinical examination, they are limited by a number of factors, including the need for additional time in the clinical environment when setting up equipment, the need for specific equipment to produce and measure rotational movement and imaging support. In addition, there are patient safety concerns from the repeated imaging. A reliable and valid clinical examination remains to be found to truly assess antero-medial rotational laxity of the knee.

[PMID]: 27705061 [Au] Autor: Lin YL; Karduna A [Ad] Endereço: 1 University of Oregon. [Ti] Título: Errors in Shoulder Joint Position Sense Mainly Come from the Glenohumeral Joint. [So] Source: J Appl Biomech;33(1):32-38, 2017 Feb. [Is] ISSN: 1543-2688 [Cp] País de publicação: United States [La] Idioma: eng [Ab] Resumo: While synchronous movement of the glenohumeral and scapulothoracic joints has been emphasized in previous kinematics studies, most investigations of shoulder joint position sense have treated the shoulder complex as a single joint. The purposes of this study were to investigate the joint position sense errors of the humerothoracic, glenohumeral, and scapulothoracic joints at different elevation angles and to examine whether the errors of the glenohumeral and scapulothoracic joints contribute to the errors of the humerothoracic joint. Fifty-one subjects with healthy shoulders were recruited. Active joint position sense of the humerothoracic, glenohumeral, and scapulothoracic joints was measured at 50°, 70°, and 90° of humerothoracic elevation in the scapular plane. The results showed that while scapulothoracic joint position sense errors were not affected by target angles, there was an angle effect on humerothoracic and glenohumeral errors, with errors decreasing as the target angles approached 90° of elevation. The results of a multiple regression analysis revealed that glenohumeral errors explained most of the variance of the humerothoracic errors and that scapulothoracic errors had a weaker predictive relationship with humerothoracic errors. Therefore, it may be necessary to test scapular joint position sense separately in addition to the assessment of the overall shoulder joint position sense.

[Ti] Título: Individuals With Patellofemoral Pain Have Less Hip Flexibility Than Controls Regardless of Treatment Outcome. [So] Source: Clin J Sport Med;27(2):97-103, 2017 Mar. [Is] ISSN: 1536-3724 [Cp] País de publicação: United States [La] Idioma: eng [Ab] Resumo: OBJECTIVE: To examine differences in hip flexibility before and after a 6-week muscle strengthening program between those with patellofemoral pain (PFP) and healthy controls. DESIGN: Single-blind, multicentered, randomized controlled trial. SETTING: Four clinical research laboratories. SUBJECTS: Physically active individuals (199 PFP and 38 controls). INTERVENTIONS: Patellofemoral pain and control subjects were randomized into either a hip-focused or a knee-focused muscle strengthening treatment program. MAIN OUTCOME MEASURES: Pain-visual analog scale (centimeter), function-Anterior Knee Pain Scale (points), flexibility-passive goniometry (degrees): hip adduction (HADD), hip external rotation (HER), hip internal rotation (HIR), total hip rotation (HROT), hip extension (HEXT) were measured before and after the muscle strengthening treatment program. RESULTS: Subjects with patellofemoral pain who successfully completed the treatment program (n = 153) had 65%, 25%, 18%, and 12% less HADD, HER, HROT, and HIR ranges of motion (ROMs), respectively, than controls (P < 0.05). Patellofemoral pain subjects who did not successfully complete the program (n = 41) had 134%, 31%, 22%, and 13% less HADD, HER, HROT, and HIR ROMs, respectively, than controls (P < 0.05). All subjects increased their HIR, HROT, and HEXT ROMs pretest to posttest (P < 0.05), but by less than 2 degree. CONCLUSIONS: Individuals with PFP had less hip flexibility than controls regardless of treatment outcome or time. After the 6-week muscle strengthening program, and regardless of treatment success, PFP and control subjects experienced a small but clinically insignificant improvement in hip flexibility. CLINICAL RELEVANCE: Hip ROM should be considered as a targeted area of focus in a rehabilitation program for physically active individuals with PFP.

[Ti] Título: Electromagnetic bone segment tracking to control femoral derotation osteotomy-A saw bone study. [So] Source: J Orthop Res;35(5):1106-1112, 2017 May. [Is] ISSN: 1554-527X [Cp] País de publicação: United States [La] Idioma: eng [Ab] Resumo: Correction of rotational gait abnormalities is common practice in pediatric orthopaedics such as in children with cerebral palsy. Femoral derotation osteotomy is established as a standard treatment, however, different authors reported substantial variability in outcomes following surgery with patients showing over- or under-correction. Only 60% of the applied correction is observed postoperatively, which strongly suggests intraoperative measurement error or loss of correction during surgery. This study was conducted to verify the impact of error sources in the derotation procedure and assess the utility of a newly developed, instrumented measurement system based on electromagnetic tracking aiming to improve the accuracy of rotational correction. A supracondylar derotation osteotomy was performed in 21 artificial femur sawbones and the amount of derotation was quantified during the procedure by the tracking system and by nine raters using a conventional goniometer. Accuracy of both measurement devices was determined by repeated computer tomography scans. Average derotation measured by the tracking system differed by 0.1° ± 1.6° from the defined reference measurement . In contrast, a high inter-rater variability was found in goniometric measurements (range: 10.8° ± 6.9°, mean interquartile distance: 6.6°). During fixation of the osteosynthesis, the tracking system reliably detected unintentional manipulation of the correction angle with a mean absolute change of 4.0° ± 3.2°. Our findings show that conventional control of femoral derotation is subject to relevant observer bias whereas instrumental tracking yields accuracy better than ±2°. The tracking system is a step towards more reliable and safe implementation of femoral correction, promising substantial improvements of patient safety in the future. © 2016 Orthopaedic Research Society.
