Forearm rotation improves after corrective osteotomy in patients with symptomatic distal radius malunion.

Objectives: Distal radius malunion can result in pain and functional complaints. One of the functional problems that can affect daily life is impaired forearm rotation. The primary aim of this study was to investigate the effect of corrective osteotomy for distal radius malunion on forearm rotation at 12 months after surgery. We secondarily studied the effect on grip strength, radiological measurements, and patient-reported outcome measurements (PROMs). Patients and methods: This cohort study analysed prospectively collected data of adult patients with symptomatic distal radius malunion. All patients underwent corrective osteotomy for malunion and were followed for 1 year. We measured forearm rotation (pronation and supination) and grip strength and analysed radiographs. PROMs consisted of the Patient-Rated Hand/Wrist Evaluation (PRWHE) questionnaire, Visual Analogue Scale for pain, and satisfaction with hand function. Results: Preoperative total forearm rotation was 112° (SD: 34°), of which supination of 49° (SD: 25°) was more impaired than pronation of 63° (SD: 17°). Twelve months after surgery, an unpaired Student's t-test showed a significant improvement of total forearm rotation to 142° (SD: 17°) (p < 0.05). Pronation improved to 72° (SD: 10°), and supination to 69° (SD: 13°) (p < 0.05). Grip strength, PROMs, as well as inclination and volar tilt on radiographs improved significantly during the first year after surgery (p < 0.05). Conclusion: In patients with reduced forearm rotation due to distal radius malunion, corrective osteotomy is an effective treatment that significantly improves forearm rotation. In addition, this intervention improves grip strength, the PRWHE-score, pain, and satisfaction with hand function.

Changes in patient-reported satisfaction and quality-of-life 6 months after rhinoplasty.

BACKGROUND: Rhinoplasty is a challenging and demanding procedure in plastic surgery. Surgical success, patient satisfaction, and improved quality-of-life are important outcomes. OBJECTIVES: This study aimed to evaluate patient-reported satisfaction with appearance, treatment, and decision outcomes as well as quality-of-life after rhinoplasty using validated questionnaires. The role of patient demographics on outcomes was also studied. METHODS: Patients who underwent a primary rhinoplasty were selected for this cohort study. Patient-reported satisfaction with appearance, treatment, and decision as well as quality-of-life were evaluated with the Utrecht Questionnaire and FACE-Q at intake and 6 months postoperatively. RESULTS: Overall, 380 patients were included. Patients reported a more positive subjective perception of nasal appearance (VAS score) at 6 months post-surgery compared with preoperative scores (7.9 ± 1.6 vs 3.2 ± 1.4, p < 0.05). Furthermore, higher quality-of-life and body image scores were observed at 6 months postoperatively compared with preoperative scores (7.7 ± 3.5 vs 15.2 ± 4.4, p < 0.05). Patients reported high satisfaction with treatment outcome (70.3 ± 23.4) as well as with their decision to undergo surgery (75.9 ± 23.4) on a scale of 0-100 at 6 months postoperatively. Patients reached similar postoperative scores regardless of their intake scores. Patients ≥30 years and patients with a history of cosmetic surgery were less satisfied postoperatively. CONCLUSION: Despite differences in appearance satisfaction at intake, most patients showed greater satisfaction with appearance, treatment, and decision outcomes as well as quality-of-life 6 months postoperatively. However, older age and a history of cosmetic surgery influenced these outcomes negatively. These factors should be considered during preoperative management of outcome expectations.

Predicting complete finger extension in Dupuytren's disease.

Multiple studies have reported the effectiveness of treatment on contracture reduction in Dupuytren's disease. However, very few studies have attempted to quantify to which extent patient and disease characteristics influence the chance of achieving a straight finger after surgery. Therefore, the aim of this study is to explore to which extent pre-operative patient and disease characteristics can reliably predict a straight finger after surgery for Dupuytren's disease. In total, 812 and 281 patients, who underwent a limited fasciectomy or needle fasciotomy, respectively, were included in the final analyses. Analysis was performed using a logistic modeling framework. For both treatments, the combination of the extension deficit at baseline; which finger is most affected, which joint is most affected, and the number of affected fingers provided reliable predictions. Classical patient characteristics, such as age and sex, had no additional predictive value. The models presented in this study provide reliable predictions and could be helpful in informing patients and managing their expectations.

Predicting Clinical Outcome After Surgical Treatment in Patients With Carpal Tunnel Syndrome.

PURPOSE: Carpal tunnel release (CTR) is typically offered to symptomatic patients with electrophysiological abnormalities when night orthoses no longer prevent waking with numbness and preferably before there is any static numbness, weakness, or atrophy. The ability to predict the amount of symptom relief after CTR could be beneficial for managing patient expectations and, therefore, improve treatment satisfaction. Therefore, the aim of this study was to identify predictors for symptom relief after CTR and to determine their contribution to symptom relief at 6 months after surgery. METHODS: A total of 1,049 patients who underwent CTR between 2011 and 2015 at 1 of 11 Xpert Clinics in the Netherlands were asked to complete online questionnaires at intake and 3 and 6 months after surgery. Patient demographics, comorbidities, and baseline scores were considered potential predictors for the amount of symptom relief on the Boston Carpal Tunnel Questionnaire (BCTQ) score, which was the primary outcome measure. RESULTS: A low score on the BCTQ at intake, a codiagnosis of a trigger finger, ulnar nerve neuropathy, trapeziometacarpal joint arthrosis, and instability or arthrosis of the wrist were associated with a smaller improvement in the BCTQ domains after a CTR at 6 months after surgery and accounted for 35% to 42% of the variance on the BCTQ domains in our multivariable regression models. CONCLUSIONS: In this study, we showed that clinical severity of carpal tunnel syndrome at intake is the most important factor in estimating symptom relief after surgical treatment. Furthermore, this study contributes to a more precise understanding of the capabilities of CTR in relieving symptoms for different subgroups of patients. Results of our study can be used to manage patient expectation on symptom relief from CTR. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic II.

Modification of the use of the extensor retinaculum for reducible distal radioulnar joint instability: technique and results.

Different surgical techniques have been described for chronic distal radioulnar joint instability: they are often complicated, quite invasive and may not be recommended for bidirectional instability. We describe a procedure using a radial-based extensor retinaculum strip and a capsular plication. This is a simple technique and less invasive than 'anatomic' radioulnar ligament reconstructions. We report the results of 38 patients (38 wrists) who we treated. After a minimum of 8 months we quantified the outcomes of the patients objectively by assessing ranges of motion, grip strength and clinical assessment of stability, and subjectively using questionnaires. Overall, 36 out of 38 patients were stable after surgery. The operated forearm and wrist had approximately 3° less range of motion in all planes and 3 kgf less grip strength compared with the unoperated side. The median Mayo modified wrist score was 90; the median visual analogue scale score was 2. This surgical technique appears to successfully treat patients with chronic reducible distal radioulnar joint instability. Anatomic reconstruction of both radioulnar ligaments is not always necessary. LEVEL OF EVIDENCE: IV.

Differences in muscle load between computer and non-computer work among office workers.

Introduction of more non-computer tasks has been suggested to increase exposure variation and thus reduce musculoskeletal complaints (MSC) in computer-intensive office work. This study investigated whether muscle activity did, indeed, differ between computer and non-computer activities. Whole-day logs of input device use in 30 office workers were used to identify computer and non-computer work, using a range of classification thresholds (non-computer thresholds (NCTs)). Exposure during these activities was assessed by bilateral electromyography recordings from the upper trapezius and lower arm. Contrasts in muscle activity between computer and non-computer work were distinct but small, even at the individualised, optimal NCT. Using an average group-based NCT resulted in less contrast, even in smaller subgroups defined by job function or MSC. Thus, computer activity logs should be used cautiously as proxies of biomechanical exposure. Conventional non-computer tasks may have a limited potential to increase variation in muscle activity during computer-intensive office work.

The effects of pause software on the temporal characteristics of computer use.

The study investigated the natural work-pause pattern of computer users and the possible effects of imposing pause regimes on this pattern. Hereto, the precise timing of computer events was recorded across a large number of days. It was found that the distribution of the pause durations was extremely skewed and that pauses with twice the duration are twice less likely to occur. The effects of imposing pause regimes were studied by performing a simulation of commercially available pause software. It was found that depending on the duration of the introduced pause, the software added 25-57% of the pauses taken naturally. Analysis of the timing of the introduced pauses revealed that a large number of spontaneous pauses were taken close to the inserted pause. Considering the disappointing results of studies investigating the effects of introducing (active) pauses during computer work, this study has cast doubt on the usefulness of introducing short duration pauses.
