Ultrasound measurements of the ECRB tendon shows remarkable variations in patients with lateral epicondylitis

Background: Lateral epicondylitis (LE) most commonly affects the Extensor Carpi Radialis Brevis (ECRB) tendon and patients are generally treated with injection therapy. For optimal positioning of the injection, as well as an estimation of the surface area and content of the ECRB tendon to determine the volume of the injectable needed, it is important to know the exact location of the ECRB in relation to the skin as well as the variation in tendon length and location. The aim of this study was to determine the variation in location and size of the ECRB tendon in patients with LE. Methods: An observational sonographic evaluation of the ECRB tendon was performed in 40 patients with LE. The length of the ECRB tendon, distance from the cutis to the center of the ECRB tendon, the length of the osteotendinous junction at the epicondyle and the distance from cutis to middle of the osteotendinous junction were measured. Results: The average tendon length was 1.68cm (range 1.27-1.98; SD 0.177). Compared to women, the ECRB tendon of men was on average 0.12cm longer. Overall, the average distance from cutis to the center of the ECRB was 0.75cm (range 0.50-1.46cm; SD 0.210), the average length of the junction was 0.55cm (range 0.35-0.87; SD 0.130), and the distance from cutis to middle of the osteotendinous junction was 0.73cm (range 0.40-1.25cm; SD 0.210). Conclusion: The size and depth of the ECRB tendon in patients with LE is largely variable. While there are no studies yet suggesting sono-guided injection to be superior to that of blind injection, the anatomic variability of this study suggests that the accuracy of injection therapy for LE might be compromised when based solely on bony landmarks and therefore not fully reliable. As a result, there is value in further studies exploring the accuracy of the ultrasound guided injection techniques

Surgical approaches for total elbow arthroplasties using data from the Dutch Arthroplasty Register

Background: Total elbow arthroplasty (TEA) is a relatively infrequently performed procedure. Therefore, nationwide databases help to provide more insight into factors that might influence implant survival, for example, the surgical approach used. Using data from the Dutch Arthroplasty Register, we aimed to reveal whether high-volume centers use different approaches than low-volume centers and whether the approach is implant specific. Methods: Using data from 2014 to 2017, we compared the surgical approaches used for high- vs. low-volume centers, as well as for the 2 most frequently used types of TEA, by use of χ2 tests. Results: We analyzed 276 procedures. In 2016 and 2017, when posterior approaches were further specified, the triceps-on approach was used most frequently in the high-volume center (27 of 42 procedures, 64%) and the triceps-flap approach was used most often in the low-volume centers (48 of 84 procedures, 57%) (P < .001). For the 2 most frequently used types of TEA, the Coonrad-Morrey and Latitude EV arthroplasties, the surgical approaches did not differ. When the high-volume center was compared with the low-volume centers, implant choice differed, with the Coonrad-Morrey arthroplasty being most often used in the high-volume center and the Latitude EV arthroplasty, in the low-volume centers. Conclusion: The posterior triceps-flap approach was the most frequently used surgical approach in primary TEA in the Netherlands, yet the triceps-on approach was used more often in the high-volume center. The surgical approaches did not differ between the 2 most frequently used types of TEA in the Netherlands

Clinical and radiographic outcome of revision surgery of radial head prostheses: midterm results in 16 patients

Little is known about revision surgery of radial head arthroplasty. The aim of this study was to report on the clinical and radiographic outcome of revision arthroplasty of the elbow with a bipolar metallic radial head prosthesis. Between 2006 and 2013, we used either a press-fit or cemented RHS bipolar radial head prosthesis for revision surgery of radial head arthroplasty in 16 patients. Patients were prospectively enrolled in the study. Differences in outcome parameters before and after revision surgery were compared. At a mean follow-up of 75 months (range, 36-116 months), none of the revised radial head prostheses needed a second revision. None of the stems showed radiographic signs of loosening. In 1 patient the head was dissociated from the prosthesis. The average flexion-extension arc was 127° (range, 105°-140°), and the average pronation-supination arc was 138° (range, 90°-160°). Stability scores improved after revision surgery, resulting in 13 stable elbows (P = .01). In 8 patients the Oxford Elbow Score was between 37 and 48 points. The percentage of patients with either good or excellent results according to the Mayo Elbow Performance Score was 63%. The mean score on the EQ-5D (EuroQol Five Dimensions) was 80 (range, 63-100), and the visual analog scale scores both for pain at rest and for pain with activity improved to 3 (range, 0-9) and 4 (range, 0-9), respectively (P  < .001). All but 1 patient was satisfied with the results of the revision procedure. The clinical and radiographic outcomes of revision surgery of a radial head prostheses are favorabl

Clinical and radiographic outcome of revision surgery of total elbow prosthesis: midterm results in 19 cases

The aim of this study is to report on the midterm outcomes and complications of revision surgery of total elbow arthroplasty. All patients who had undergone total elbow arthroplasty revision surgery between 2009 and 2014 with semiconstrained total elbow prostheses were prospectively enrolled in the study. Records were reviewed for demographic data; baseline measurements; and several follow-up assessments including the Mayo Elbow Performance Score (MEPS), visual analog scale (VAS) score for pain, Oxford Elbow Score, range of motion, satisfaction, and radiographs. A total of 19 revision arthroplasties were included. At a mean follow-up of 57 months, there had been 1 rerevision and 2 removals. One patient was excluded from follow-up because of confounding comorbidity. At last follow-up, MEPS values and VAS pain scores both improved (P  < .01). The rate of combined good and excellent results on the MEPS was 53%. The mean VAS scores for pain at rest and with activity were 2 and 4, respectively. Fair results for the Oxford Elbow Score were reported, with a mean score of 28 points. Range of motion improved to an average flexion-extension arc of 108° (P  < .01), and the pronation-supination arc improved to an average of 123° (P  < .01). All elbows were stable at last follow-up (P  < .01). Radiographs showed nonprogressive osteolysis around the prosthesis in 3 cases (19%) and suspicion of loosening in 1 (6%). In 11 patients postoperative complications occurred. Of 15 patients, 13 (87%) were satisfied with the result of the revision procedure. Revision of total elbow prostheses leads to satisfactory results, less pain, and better elbow function. This procedure is related to a relatively high complication rat

Higher Function Scores and Satisfaction in Patients with Anteromedial Osteoarthritis Compared with Other Wear Patterns of the Knee: 2 Years after Both Total and Unicondylar Knee Arthroplasties

Anteromedial osteoarthritis (AMOA) is a common wear pattern in primary osteoarthritic knees. In patients with bone-on-bone disease, the most appropriate surgical intervention is still a matter of debate. Knee arthroplasty is a well-accepted treatment to relieve symptoms and regain function. Unfortunately, satisfaction is limited, especially related to activities. A cross-sectional study was performed among patients treated with total knee arthroplasty (TKA) and unicondylar arthroplasty (UKA) to determine if the osteoarthritis wear pattern or type of prosthesis affects knee-specific function scores and satisfaction related to activities. All UKA patients (N = 100) were treated for AMOA. Based on radiological assessment of the wear pattern, TKA patients were divided into two groups: TKA for AMOA (N = 68) and true TKA (N = 99). The Knee injury and Osteoarthritis Outcomes Score (KOOS), new Knee Society score (KSS), anterior knee pain scale, visual analog scales (VASs) for satisfaction about activities, and net promoter score were collected. After 2 years' follow-up, the anterior knee pain scale and VAS satisfaction showed significantly better scores for patients treated with TKA for AMOA compared with the true TKA group. Also in the KOOS subscales, some differences were seen in favor of the TKA for AMOA group. The new KSS was not in favor of a specific wear pattern, but patients with AMOA treated with UKA performed better on the symptoms subscale compared with patients treated with TKA. In conclusion, patients treated with TKA for AMOA showed better knee-specific function scores and satisfaction scores compared with patients treated with TKA for other wear patterns, and only slight differences were found between both the AMOA groups (TKA for AMOA and UKA). Thus, the radiologic assessment of wear patterns might be useful to take into account the shared decision-making process, when discussing expectations, timing, and outcomes with knee osteoarthritis patients considering knee arthroplasty. When AMOA is present, it might be beneficial to choose UKA over TKA

Comparison of isometric triceps brachii force measurement in different elbow positions

Purpose: Objective and reliable force measurement is necessary to monitor the rehabilitation after triceps brachii pathology, injuries, and posterior approach–based surgery. It is unclear at which amount of extension the triceps is best tested and if comparison to the uninjured sided is reliable. This study aims to identify the most reliable elbow position at which elbow extension force is measured using a dynamometer. Furthermore, it aims to compare the extension strength of the dominant arm with that of the nondominant arm. Methods: Isometric elbow extension force of the dominant and nondominant arms of healthy subjects was measured. The measurements were taken in three sequences per arm in 0, 30, 60, 90, and 120 degrees of flexion. A subgroup repeated the measurements to analyze test–retest reliability using intraclass correlation. Results: We included a total of 176 volunteers. The repeated measures analysis of variance for within-subject effect showed the lowest variation coefficient at 30 degrees of flexion. Extension forces showed a mean difference of 3.2–6.9 N in advantage of the dominant arm, resulting in ratios from 1.05 to 1.09. Learning curve analysis showed that during the first session in dominant and nondominant arms, less forces were exerted. Conclusion: The most reliable isometric triceps brachii muscle strength measurement was at 30 degrees of flexion of the elbow. Considering the learning curve, a first tryout session for both arms is indicated. Then, a second measurement suffices as no further learning curve is observed

Continuous passive motion and physical therapy (CPM) versus physical therapy (PT) versus delayed physical therapy (DPT) after surgical release for elbow contractures; a study protocol for a prospective randomized controlled trial

Abstract Background The elbow is prone to stiffness after trauma. To regain functional elbow motion several conservative- and surgical treatment options are available. Conservative treatment includes physical therapy, intra-articular injections with corticosteroids and a static progressive or dynamic splinting program. If conservative treatment fails, an operative release of the posttraumatic stiff elbow is often performed. The best Evidence-Based rehabilitation protocol for patients after an operative release is unknown to date and differs per surgeon, hospital and country. Options include early- or delayed motion supervised by a physical therapist, immediate continuous passive motion (CPM), (night) splinting and a static progressive or dynamic splinting program. Methods/design The SET-Study (Stiff Elbow Trial) is a single-centre, prospective, randomized controlled trial. The primary objective of this study is to compare the active Range of Motion (ROM) (flexion arc and rotational arc) twelve months after surgery between three groups. The first group will receive in-hospital CPM in combination with early motion Physical Therapy (PT) supervised by a physical therapist, the second group will receive only in-hospital early motion PT supervised by a physical therapist and the third group will receive outpatient supervised PT from postoperative day seven till ten. Secondary outcome measures will be Patient Reported Outcome Measures (PROMs) including the Mayo Elbow Performance Score (MEPS), the Oxford Elbow Score (OES), the quick Disabilities of Arm, Shoulder and Hand (qDASH) score, Visual Analogue pain Scale in rest and activity (VAS), Pain Catastrophizing Scale (PCS), the Short Form (SF)-36, the Centre for Epidemiological Studies Depression Scale Revised (CESD-R) and the Work Rehabilitation Questionnaire (WORQ) for the upper limb. Discussion A successful completion of this trial will provide evidence on the best rehabilitation protocol in order to (re)gain optimal motion after surgical release of the stiff elbow. Trial registration The trial is registered at the Dutch Trial Register: NTR6067 , 31–8-2016
