Abstract

To cross-culturally adapt the Patient-Rated Wrist Evaluation form (PRWE) into German (PRWE-G) and to evaluate its reliability and validity. A cross-cultural adaptation of the PRWE was carried out, according to established guidelines. 103 patients, who had undergone resection interposition arthroplasty (RIAP) for carpometacarpal osteoarthritis approximately 6.2 years earlier, completed a questionnaire booklet containing the PRWE-G, the Short Form 36 (SF-36), the Disabilities of Arm, Shoulder, and Hand (DASH); they also underwent clinical assessment with the Hand Function Index (HFI, Keitel) and Custom Score including grip and pinch strength tests. The results were used to assess the criterion and construct validity of the PRWE-G. To measure the re-test reliability, 51 patients completed a second PRWE-G within 2 weeks. The test-retest reliability of the PRWE-G was acceptable for the pain and function sub-scales and for the global score, with intraclass correlation coefficients of 0.78-0.87. The PRWE-G showed a high internal consistency (Cronbach's alphas of 0.92-0.97 for the scales and the total score). The typical error of measurement for the global score was 8.1 points, giving a minimal detectable change (MDC 95% ) of approximately 22.5 points. The PRWE-G scores correlated well with those of the DASH (r=0.82, p<0.001) but less well with those of the physical component summary of the SF-36 (r=0.53, p<0.001) and not at all with the mental component summary scores of the SF-36 (r=0.04, p>0.05). The PRWE-G scores correlated moderately with certain clinical findings of the HFI, Custom Score, and grip/pinch strength tests (r=0.30-0.59, p<0.001). The PRWE-G represents a valid and reliable instrument to evaluate self-rated outcome in German-speaking patients with hand and wrist pathology.
... PRW/HE is a patient self-reported questionnaire, which is internationally, widely -used, wristhand specific. It has been translated into several European and Asian languages, (13)(14)(15)(16)(17)(18) which has also been adapted to suit the culture of each country accordingly. In Southeast Asia countries, PRW/HE have been widely used in Singapore, in which they developed and made an evaluation for Chinese version of the PRW/HE. ...
... At follow-up, the same parameters were assessed, all four, and validated and in the German language available patient-rated outcome measures (PROMs) were completed and standard anteroposterior and lateral radiographs were obtained. PROMs used were the German versions of DASH, PRWE, EQ-5D-3L, and SF-36 [23][24][25][26]. Radiographic measurements were performed by the author on both the preoperative and postoperative radiographs. ...

Introduction: The purpose of this study was the evaluation of surgical outcomes in a series of wrists with Madelung's deformity treated with radial corrective osteotomy. We hypothesize that this surgical technique is a suitable and safe way of treatment. Materials and methods: A retrospective review of patients with Madelung's deformity treated with radial corrective osteotomy between January 2001 and June 2017 at a single large department of hand surgery in Germany was performed. Patients who met the inclusion criteria were invited for follow-up and outcome variables including pain, range of motion, patient-rated outcome measures, and radiographic measurements were obtained for comparison with preoperative data collected from the patients' medical records. Results: 14 wrists were included. The average age at the time of surgery was 21.9 years, and the average follow-up was 7.2 years. The average visual analog pain scale at rest decreased from preoperative 2.6 points to postoperative 0.7 points. Under strain, the average VAS declined from 7.4 to 4.9 points. The mean DASH Score decreased from 42.9 before surgery to 22.0 points after surgery. Range of motion improved slightly in five out of six directions of motion, with the greatest increase seen in average supination from preoperative 68.5° to postoperative 82.0°. Averages of all five measured McCarroll's parameters and ulnar variance decreased, as expected from corrective surgery. Four wrists (26.8%) needed subsequent procedures. Conclusion: Radial corrective osteotomy was a suitable treatment of Madelung's deformity in our collective, although surgical outcomes are not yet fully satisfying.
... Wrist-related pain and disability was assessed using the Patient-Rated Wrist Evaluation (PRWE). 20,21 The score ranges from 0 to 100, with lower scores indicating lower pain and disability. Active range of motion of the wrist was calculated by measuring both the pronation-supination and flexion-extension arcs of motion using a goniometer. ...

Purpose We evaluated the 1-year postoperative clinical and patient-reported outcomes in patients who had a 3-dimensional planned corrective osteotomy of their distal radius, radial shaft, or ulnar shaft using a printed, anatomical, patient-tailored plate to determine the feasibility and effectiveness of this methodology. Methods Simulations in computer-assisted preoperative planning of corrective osteotomies resulted in 3-dimensionally printed surgical guides, surgical models, and anatomically customized plates for application at the distal radius and forearm. Patients with malunions of the distal radius or forearm who underwent fixation with the custom-made plates were documented in our registry. Grip strength and range of motion assessments were made before surgery (baseline), as well as at 6 weeks and 3 and 12 months. Additionally, patients rated their wrist-related pain and disability using the Patient-Rated Wrist Evaluation. Results Fifteen patients underwent corrective surgery, and the 1-year follow-up data of 14 patients with a median age of 56 years (interquartile range, 24–64 years) were available for analysis. The median baseline Patient-Rated Wrist Evaluation score improved from 47 to 7 after 1 year. The flexion-extension arc of motion of the wrist increased from 90° at baseline to 130° at 1 year and the pronation-supination arc of motion of the wrist increased from 135° to 160° in the same time period. Differences in radiological measurements for palmar and radial inclinations, as well as for ulnar variance between the affected and contralateral wrists, were reduced with the osteotomy. In 1 case, the plate was removed 11 months after the osteotomy. No severe adverse events were reported. Conclusions Three-dimensionally planned and printed patient-tailored plates offer a reliable method for correcting even complex malunions of the distal radius and forearm. Type of study/level of evidence Therapeutic IV.
... PRWE [22] is a joint-specific questionnaire that enquires about symptoms of the wrist (presence, intensity, and frequency of pain) and functional limitations concerning activities of daily living (ADL). The response scale is numeric from 0 to 100 points (0 = best, 100 = worst rating) [23]. ...

Introduction Given the absence of a satisfying plate system to deal with multifragmentary or subcapital distal ulnar fractures, the Distal Ulna Locking Plate (DUL, I.T.S. GmbH, Graz, Austria) could become a useful treatment option. This study aimed to evaluate the results of this anatomically pre-contoured plate regarding patients with unstable or displaced distal ulnar fractures. Methods In a prospective clinical trial, 20 patients (18 female, two male; mean age 70 years (24–91 years)) with unstable or displaced distal ulna fractures between December 2010 and August 2015 were analyzed. All patients were treated with open reduction and internal fixation using the DUL. They were evaluated at three follow-up appointments at 3, 6 and 12 months postoperatively regarding their bone healing, ulnar variance (UV), range of motion (ROM) and grip strength. Patient related outcomes were measured using the Disability of the Arm, Shoulder and Hand (DASH), the Patient Rated Wrist Evaluation (PRWE) questionnaires, and the Visual Analogue Scale (VAS). The results after one year were compared to the outcome of the healthy contralateral side. Results All fractures treated with open reduction and internal fixation using the Distal Ulna Locking Plate healed within 6 months and showed stable ulnar variances after surgery. ROM (rotational plane 81.1 ± 9.0°, sagittal plane 55.1 ± 14.6°, frontal plane 33.0 ± 9.4°) and grip strength (18.7 ± 7.1 N) at the follow-up after 12 month had similar values compared with the uninjured side. The mean DASH score (36.4 ± 29.0), the PRWE-score (14.5 ± 27.0), and the VAS (at rest 0.5 ± 1.1, during activity 1.2 ± 2.4) after one year had no significant difference to the uninjured side. The surgeon’s overall satisfaction rate regarding plate handling reached 81.8%. Conclusion Stabilization of unstable distal ulna fractures using the DUL restores nearly normal anatomy and function. Its pre-countered design, volar placement, and enhanced stability present a satisfying plate system. Trial registration The trial was retrospectively Registered at www.clinicaltrials.gov on 16 December 2021 (Trial Registration Number: NCT05329012).
... As an independent and straightforward tool to measure the influence of the TMC symptoms on daily activities and function, we decided to use the standardized questionnaire "patient-rated wrist evaluation" (PRWE) [21]. This questionnaire is validated and consists of 5 questions about pain and 10 questions on function. ...

Background: Retrospective studies have described the effectiveness of low-dose radiotherapy (LD-EBRT) in painful arthrosis of small finger joints, but two recent prospective studies have yielded ambiguous results. To generate accurate data for the planning of a trial, we conducted a prospective, monocentric, observational study to describe the effects of LD-EBRT as precisely as possible. Methods: Twenty-five consecutive patients with symptomatic trapeziometacarpal (TMC) arthrosis were irradiated with 6 × 0.5 Gy. Before, 3, and 12 months after LD-EBRT, we assessed subjective endpoints (modified “von-Pannewitz score”, 10-point visual analogue scale (VAS), “patient-rated wrist evaluation” (PRWE)), and objective measurements (“active range of motion” (AROM), Kapandji index, grip strength, pinch grip). Results: At 3/12 months, 80%/57% reported partial and 4%/18% complete remission according to the “von-Pannewitz” score. VAS “overall pain” significantly decreased from a median of seven (IQR 4) at baseline to three (IQR 6; p = 0.046) and to two (IQR 2; p = 0.013). Similar results were obtained for VAS “pain during exercise”, VAS “pain during daytime”, and VAS “function”. “PRWE overall score” was reduced from 0.5 at baseline (SD 0.19) to 0.36 (SD 0.24, p = 0.05) and to 0.27 (SD 0.18, p = 0.0009). We found no improvements of the objective endpoints (AROM, Kapandji, grip strength) except for flexion, which increased from 64° (SD 12°) at baseline to 73° (SD 9.7°, p = 0.046) at 12 months. Conclusions: We recommend the PRWE score as a useful endpoint for further studies for this indication. To prove a 15% superiority over sham irradiation, we calculated that 750 patients need to be prospectively randomized.

Zusammenfassung Hintergrund Die Madelung-Deformität ist eine angeborene oder erworbene Wachstumsstörung des Unterarmes, die für betroffene Patienten mit erheblichen Einschränkungen der Lebensqualität einhergehen kann. In der Literatur wurden verschiedene Möglichkeiten der operativen Therapie der Erkrankung beschrieben. Mit der vorliegenden Studie sollte der Frage nachgegangen werden, ob die Physiolyse mit Resektion des Vickers-Bandes die Progredienz der Erkrankung in einem eigenen jungen Patientenkollektiv erfolgreich aufhalten konnte, wie es anhand der bisherigen Literatur zu diesem Thema zu erwarten wäre. Material und Methoden Die Akten aller Patienten mit Madelung-Deformität, die zwischen Januar 2001 und Juni 2017 primär mit einer Physiolyse mit Resektion des Vickers-Bandes behandelt worden sind, wurden retrospektiv ausgewertet. Die Patienten wurden zu einer Nachuntersuchung eingeladen und bezüglich des OP-Outcomes untersucht. Erhoben wurden Schmerzen in Ruhe und unter Belastung, der Bewegungsumfang der Handgelenke und das Aktivitätsniveau. Zudem wurden von jedem operierten Handgelenk Röntgenbilder in zwei Ebenen angefertigt und radiologische Messungen durchgeführt. Die so erhobenen Daten wurden mit den Daten aus den Patientenakten verglichen. Ergebnisse 9 Handgelenke wurden eingeschlossen. Das Durchschnittsalter zum Zeitpunkt der Operation lag bei 13,2 Jahren, der durchschnittliche Nachbeobachtungszeitraum betrug 5,0 Jahre. Die Extension und Ulnarduktion nahmen von präoperativ bis zur Nachuntersuchung leicht ab, während sich die Beugung minimal sowie die Radialduktion und die Unterarmdrehung erkennbar verbesserten. Der Punktwert für Ruheschmerzen auf der visuellen Analogskala stieg von präoperativ 0,25 Punkten auf 1,88 Punkte zum Zeitpunkt der Nachuntersuchung. Unter Belastung stieg der durchschnittliche Punktwert für Schmerzen von 2,00 auf 4,25 Punkte. Der mittlere DASH-Score stieg von 6,04 Punkten vor der Operation auf 12,20 Punkte zum Zeitpunkt der Nachuntersuchung. Die Durchschnittswerte von zwei der fünf gemessenen McCarroll-Parameter stiegen an, im Fall der Absenkung des Os Lunatum statistisch signifikant. Bei einem Handgelenk war ein Folgeeingriffe erforderlich. Schlussfolgerung Die Progredienz der Madelung-Deformität konnte in unserem Kollektiv durch die Physiolyse mit Resektion des Vickers-Bandes nur teilweise aufgehalten und eine signifikante Zunahme der Schmerzsymptomatik im Untersuchungszeitraum nicht vermieden werden. Bei Patienten, die vor Abschluss ihres Längenwachstums stehen, sollte dieses Verfahren daher mit Zurückhaltung eingesetzt werden.

Es liegt zwischen Kahn- und Mondbein und spielt für die Stabilität des Handgelenks eine große Rolle: das skapholunäre Band (SL-Band). Reißt das Band, kann ein neues konservatives Trainingsprogramm Patient*innen helfen, die Hand wieder schmerzfrei und im gewohnten Ausmaß zu bewegen.

Purpose The purpose of this study was to assess the short- to mid-term radiologic, clinical, and functional outcomes of patients treated with combined dorsal and volar locking plating for internal fixation of complex, comminuted, intra-articular, distal radius fractures. Methods We performed a retrospective review of 34 patients treated with combined dorsal and volar locking plates for the internal fixation of complex, comminuted, intra-articular distal radius fractures. Radiographic and clinical parameters were recorded at a mean of 48 months after surgery. Activities of daily living and quality of life were assessed by the Disabilities of the Arm, Shoulder, and Hand and Patient-Rated Wrist Evaluation questionnaires. Results Compared with the contralateral wrist, the treated wrist regained 73% of flexion, 81% of extension, 86% of ulnar deviation, 90% of radial deviation, 98% of pronation, 99% of supination, and 93% of grip strength. Mean Disabilities of the Arm, Shoulder, and Hand and Patient-Rated Wrist Evaluation scores were 11 (range, 0–78) and 11 (range, 0–77), respectively. Radial height and radial inclination were restored anatomically in 24% and 41% of patients, respectively, while volar tilt and ulnar variance were restored in 68% of patients. Conclusion The overall functional and radiologic outcome of patients with comminuted intra-articular complex distal radius fractures treated with the combined dorsovolar plate osteosynthesis was good to excellent. Level of Evidence Therapeutic IV.

The content of selenium (Se) in forage samples and the blood activity of glutathione peroxidase (GSH-Px; EC 1.11.1.9) of groups of lactating cows and heifers were evaluated between autumn and spring of 1999 in 12 dairy herds from IXth Region (38º S and 71º W) of Chile. Se-concentration was determined in forage samples by using inductively coupled plasma mass spectroscopy (ICP-MS). The activity of GSH-Px was determined through a kinetic technique NADPH-dependant. Mean, standard deviation and range were obtained, and the groups were compared by ANOVA test and the values compared to reference values. The content of Se in forage samples was 0.03±0.02 ppm, the range was between 0.05). Heifers showed a lower activity for GSH-Px than cows in both periods (p

This paper describes the development of an evaluative outcome measure for patients with upper extremity musculoskeletal conditions. The goal is to produce a brief, self-administered measure of symptoms and functional status, with a focus on physical function, to be used by clinicians in daily practice and as a research tool. This is a joint initiative of the American Academy of Orthopedic Surgeons (AAOS), the Council of Musculoskeletal Specialty Societies (COMSS), and the Institute for Work and Health (Toronto, Ontario).Our approach is consistent with previously described strategies for scale development. In Stage 1, Item Generation, a group of methodologists and clinical experts reviewed 13 outcome measurement scales currently in use and generated a list of 821 items. In Stage 2a, Initial Item Reduction, these 821 items were reduced to 78 items using various strategies including removal of items which were generic, repetitive, not reflective of disability, or not relevant to the upper extremity or to one of the targeted concepts of symptoms and functional status. Items not highly endorsed in a survey of content experts were also eliminated. Stage 2b, Further Item Reduction, will be based on results of field testing in which patients complete the 78-item questionnaire. This field testing, which is currently underway in 20 centers in the United States, Canada, and Australia, will generate the final format and content of the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire. Future work includes plants for validity and reliability testing. © 1996 Wiley-Liss, Inc.

This study was a literature review of the quality of four disease-specific functional status questionnaires for patients with low back pain: Oswestry; Million; Roland; and Waddell disability questionnaire. The questionnaires were evaluated in terms of general description, scale structure, reliability, validity, responsiveness, and clinical research applications. Functional status is an outcome of great interest for clinical trials of low back pain. A computer-aided search was conducted of articles published between 1981 and 1993 and references given in selected relevant publications. Articles were selected if at least one of the four functional status questionnaires was used or if the authors gave relevant information about the methodology of these questionnaires. There was not enough information available about the criteria of item selection used for the development of the questionnaires. The test-retest reproducibility of the questionnaires seemed satisfactory. The Oswestry and Roland disability questionnaires have been used and evaluated more frequently than the Million and Waddell. Therefore, we can be more certain about the validity and responsiveness of the former pair of questionnaires. In the absence of a gold standard, direct comparisons of evaluative functional status questionnaires in a single patient group are needed. Through direct comparisons, comparative validity and responsiveness can be assessed. Functional status measures are not currently used in many settings in which they would be valuable. It is important to encourage their wider use in clinical trials. Additional research is needed to compare and improve the existing questionnaires.

The goal of this project was to develop a more comprehensive and sensitive version of the Arthritis Impact Measurement Scales (AIMS). AIMS scale items were revised, and 3 new scales were added to evaluate arm function, work, and social support. Sections were also added to assess satisfaction with function, attribution of problems to arthritis, and self-designation of priority areas for improvement. The new instrument was designated the AIMS2. A pilot test of format and content and a performance test of reliability and validity were carried out. Questionnaire completion times in a pilot study of 24 subjects averaged 23 minutes, and evaluations were positive regarding the instrument's length and ease of completion, and the subjects' willingness to complete serial forms and return them by mail. Measurement performance was tested in 408 subjects: 299 with rheumatoid arthritis (RA) and 109 with osteoarthritis (OA); 45 of these subjects completed a second AIMS2 within 3 weeks. Internal consistency coefficients for the 12 scales were 0.72-0.91 in the RA group and 0.74-0.96 in the OA group. Test-retest reliability was 0.78-0.94. All within-scale factor analyses produced single factors, except for mobility level in OA. Validity analyses in both the RA and the OA groups showed that patient designation of an area as a problem or as a priority for improvement was significantly associated with a poorer AIMS2 scale score in that area. Reliability, factor analysis, and validity results were consistent in age, sex, and education subgroups. Satisfaction was moderately correlated with level of function in the same health status area, and the satisfaction items formed a reliable scale. Responses to the arthritis attribution items showed that most dysfunction in this sample was due to arthritis. The AIMS2 is a revised and expanded health status questionnaire with excellent measurement properties that should be useful in arthritis clinical trials and in outcomes research.

A structure for representation of patient outcome is presented, together with a method for outcome measurement and validation of the technique in rheumatoid arthritis. The paradigm represents outcome by five separate dimensions: death, discomfort, disability, drug (therapeutic) toxicity, and dollar cost. Each dimension represents an outcome directly related to patient welfare. Quantitation of these outcome dimensions may be performed at interview or by patient questionnaire. With standardized, validated questions, similar scores are achieved by both methods. The questionnaire technique is preferred since it is inexpensive and does not require interobserver validation. These techniques appear extremely useful for evaluation of long term outcome of patients with rheumatic diseases.

Clinicians and researchers without a suitable health-related quality of life (HRQOL) measure in their own language have two choices: (1) to develop a new measure, or (2) to modify a measure previously validated in another language, known as a cross-cultural adaptation process. We propose a set of standardized guidelines for this process based on previous research in psychology and sociology and on published methodological frameworks. These guidelines include recommendations for obtaining semantic, idiomatic, experiential and conceptual equivalence in translation by using back-translation techniques and committee review, pre-testing techniques and re-examining the weight of scores. We applied these guidelines to 17 cross-cultural adaptation of HRQOL measures identified through a comprehensive literature review. The reporting standards varied across studies but agreement between raters in their ratings of the studies was substantial to almost perfect (weighted kappa = 0.66-0.93) suggesting that the guidelines are easy to apply. Further research is necessary in order to delineate essential versus optional steps in the adaptation process.

In the present study saddle joints of the thumb and neighboring joints of 100 anatomic specimens are examined with regard to radiological and macroscopic arthrotic alterations. Comparisons of radiological and macroscopic findings demonstrate that early arthrotic articular alterations cannot be diagnosed radiologically. Almost half of the hands examined displayed arthrotic lesions in the saddle joint of the thumb, whereas the trapezoido-scaphoidal and trapezio-scaphoidal joints are each affected in one third. Hands with manifest thumb saddle joint arthrosis are accompanied by arthrotic alterations of the joints between the scaphoid, trapezium and trapezoid in two-thirds of the cases. In the remaining radial intercarpal joints, no macroscopic evidence can be ascertained of arthrotic alterations. Among the processes discussed as causal factors of simultaneous incidence of scaphoidal and carpo-metacarpal arthroses, the architecture of the osseous carpus, the individual expression of the scaphoid bone and poly- or secondary arthrotic processes are important.
