What counts: outcome assessment after distal radius fractures in aged patients

The ageless approach: Nonoperative mastery competes head-on with surgery for elderly distal radius fractures

The aim of the current study is to compare the clinical outcomes of cast immobilization (CI) versus surgical treatment after 1 year for distal radius fractures (DRFs) in the elderly population. The cohort included patients aged 70-89 who suffered an acute, closed, and displaced DRF and who were treated conservatively or surgically at our clinic between August 2018 and January 2022. Those who had pathological fractures, open fractures, concomitant ulna fractures (except ulna styloid fractures), were not between the ages of 70 and 89, or refused to participate were excluded from the study. The study gathered data on patient demographics, initial radiological measurements, clinical measurements after 1 year, treatment models employed, and rates of complications. Of the total number of patients (276), CI was used on 77.2% (213), whereas the other 25 had volar-locked plates (VLP), 25 received external fixators with percutaneous pinning (EFPP), and 13 had isolated percutaneous pinning (IPP). 19 of 276 individuals had complications, with Complex Regional Pain Syndrome and Carpal Tunnel Syndrome being the most often documented. EFPP resulted in significantly higher Disability of the Arm, Shoulder, and Hand (DASH) score values than VLP and IPP at the 1st postoperative year (p < 0.05). No statistically significant difference was found between the DASH score and ROM values at the 1st postoperative year for patients who received CI versus those who underwent surgery (p > 0.05). In the first postoperative year, CI still retains its validity and performs similarly to surgery for DRFs in older individuals. VLPP and IPP methods outperformed EFPP surgeries.

The contribution of lower-mineralized tissue to the healing of distal radius fractures assessed using HR-pQCT

High-resolution peripheral quantitative CT (HR-pQCT) enables quantitative assessment of distal radius fracture healing. In previous studies, lower-mineralized tissue formation was observed on HR-pQCT scans, starting early during healing, but the contribution of this tissue to the stiffness of distal radius fractures is unknown. Therefore, the aim of this study was to investigate the contribution of lower-mineralized tissue to the stiffness of fractured distal radii during the first twelve weeks of healing. We did so by combining the results from two series of micro-finite element (μFE-) models obtained using different density thresholds for bone segmentation. Forty-five postmenopausal women with a conservatively-treated distal radius fracture had HR-pQCT scans of their fractured radius at baseline (BL; 1-2 weeks post-fracture), 3-4 weeks, 6-8 weeks, and 12 weeks post-fracture. Compression stiffness (S) was computed using two series of μFE-models from the scans: one series (Msingle) included only higher-mineralized tissue (>320 mg HA/cm3), and one series (Mdual) differentiated between lower-mineralized tissue (200-320 mg HA/cm3) and higher-mineralized tissue. μFE-elements were assigned a Young's Modulus of 10 GPa (higher-mineralized tissue) or 5 GPa (lower-mineralized tissue), and an axial compression test to 1 % strain was simulated. The contribution of the lower-mineralized tissue to S was quantified as the ratio Sdual/Ssingle. Changes during healing were quantified using linear mixed effects models and expressed as estimated marginal means (EMMs) with 95 %-confidence intervals (95 %-CI). Median time to cast removal was 5.0 (IQR: 1.1) weeks. Sdual and Ssingle gradually increased during healing to a significantly higher value than BL at 12 weeks post-fracture (both p < 0.0001). In contrast, Sdual/Ssingle was significantly higher than BL at 3-4 weeks post-fracture (p = 0.0010), remained significantly higher at 6-8 weeks post-fracture (p < 0.0001), and then decreased to BL-values at the 12-week visit. EMMs ranged between 1.05 (95 %-CI: 1.04-1.06) and 1.08 (95 %-CI: 1.07-1.10). To conclude, combining stiffness results from two series of μFE-models obtained using single- and dual-threshold segmentation enables quantification of the contribution of lower-mineralized tissue to the stiffness of distal radius fractures during healing. This contribution is minor but changes significantly around the time of cast removal. Its course and timing during healing may be clinically relevant. Quantification of the contribution of lower-mineralized tissue to stiffness gives a more complete impression of strength recovery post-fracture than the evaluation of stiffness using a single series of μFE-models.

Analysis of Postoperative Distal Radius Fracture Outcomes in the Setting of Osteopenia and Osteoporosis for Patients with Comorbid Conditions

Purpose

Distal radius fractures (DRFs) are among the most common orthopedic injuries, especially in the elderly. A wide variety of approaches have been advocated as successful treatment modalities; yet, there remains variability in practice patterns of DRF in patients with osteoporosis and osteopenia. Using large data set analysis, we sought to determine the risk profile of operative fixation of DRF in patients with low bone mineral density.

Methods

A commercially available health care database, PearlDiver, was queried for all patients who underwent open reduction internal fixation of DRFs between 2010 and 2020. The study population was divided into groups based on the presence or absence of osteopenia or osteoporosis and was further classified by patients who were receiving bisphosphonate therapy. Complication rates were calculated, including rates of malunion, surgical site infection, osteomyelitis, hardware failure, and hardware removal. Five-year future fragility fractures were defined in hip, vertebrae, humerus, and wrist fractures. Chi-square analysis and logistic regression were performed to determine an association between these comorbidities and various postoperative complications.

Results

A total of 152,926 patients underwent open reduction internal fixation of a DRF during the study period. Chi-square analysis of major complications at 3 months showed a statistically significant increase in malunion in patients with osteopenia (P = .05) and patients with osteoporosis (P = .05) who underwent open reduction internal fixation. Logistic regression analysis at 12 months after surgery demonstrated that osteopenia was associated with an increased risk of hardware failure (P < .0001), hardware removal (P < .0001), surgical site infection (P < .0001), and malunion (P = .004). Osteoporosis was associated with a significantly increased risk of hardware failure (P = .01), surgical site infection (P < .0001), and malunion (P < .0001).

Conclusions

We demonstrated, using large data set analysis, that DRF patients with osteopenia and osteoporosis are predicted to be at increased risk of multiple postoperative complications, and thus, bone density should be strongly considered in treatment planning for these patients.

Functional outcome measures for distal radius fractures: A systematic review

Objective: This systematic review aimed to identify and describe the utility of functional outcome measures reported in intervention trials between 2010 and 2020, and to map these measures to the International Classification of Functioning, Disability and Health (ICF) model.

Method: The search was carried out on MEDLINE, CINAHL and Cochrane Register of Clinical Trials. Peer-reviewed intervention studies detailing the functional outcome measures used for any treatment for distal radius fracture were selected. Participant characteristics, outcome measures reported and the trends in their use over time and geographical locations were extracted.

Results: This review analysed 119 studies. Thirty-one functional outcome measures were used across 36 countries. Ninety-two percent of studies measured both the Body Function/Structure and Activity/Participation domains of the ICF. The most frequently used measures were the Disabilities of the Arm, Shoulder and Hand Questionnaire, Range of Motion and Grip Strength. There is a lack of measures on successful return to meaningful occupation.

Conclusion: The outcome measures identified were equally spread across the ICF domains. There is a growing importance of Patient-Reported Outcome Measures to supplement performance-based measures, but a lack of measure on successful return to meaningful occupation.

Which Factors Are Associated With Satisfaction With Treatment Results in Patients With Hand and Wrist Conditions? A Large Cohort Analysis

BACKGROUND

Satisfaction with treatment results is an important outcome domain in striving for patient-centered and value-based healthcare. Although numerous studies have investigated factors associated with satisfaction with treatment results, most studies used relatively small samples. Additionally, many studies have only investigated univariable associations instead of multivariable associations; to our knowledge, none have investigated the independent association of baseline sociodemographics, quality of life, improvement in pain and function, experiences with healthcare delivery, and baseline measures of mental health with satisfaction with treatment results.

QUESTIONS/PURPOSES

(1) What factors are independently associated with satisfaction with treatment results at 3 months post-treatment in patients treated for common hand and wrist conditions? (2) What factors are independently associated with the willingness to undergo the treatment again at 3 months post-treatment in patients treated for common hand and wrist conditions? Among the factors under study were baseline sociodemographics, quality of life, improvement in pain and function, experiences with healthcare delivery, and baseline measures of mental health.

METHODS

Between August 2018 and May 2020, we included patients who underwent carpal tunnel release, nonsurgical or surgical treatment for thumb-base osteoarthritis, trigger finger release, limited fasciectomy for Dupuytren contracture, or nonsurgical treatment for midcarpal laxity in one of the 28 centers of Xpert Clinics in the Netherlands. We screened 5859 patients with complete sociodemographics and data at baseline. Thirty-eight percent (2248 of 5859) of these patients had complete data at 3 months. Finally, participants were eligible for inclusion if they provided a relevant answer to the three patient-reported experience measure (PREM) items. A total of 424 patients did not do this because they answered "I don't know" or "not applicable" to a PREM item, leaving 31% (1824 of 5859) for inclusion in the final sample. A validated Satisfaction with Treatment Result Questionnaire was administered at 3 months, which identified the patients' level of satisfaction with treatment results so far on a 5-point Likert scale (research question 1, with answers of poor, moderate, fair, good, or excellent) and the patients' willingness to undergo the treatment again under similar circumstances (research question 2, with answers of yes or no). A hierarchical logistic regression model was used to identify whether baseline sociodemographics, quality of life, change in outcome (patient-reported outcome measures for hand function and pain), baseline measures of mental health (including treatment credibility [the extent to which a patient attributes credibility to a treatment] and expectations, illness perception, pain catastrophizing, anxiety, and depression), and PREMs were associated with each question of the Satisfaction with Treatment Result Questionnaire at 3 months post-treatment. We dichotomized responses to our first question as good and excellent, which were considered more satisfied, and poor, moderate, and fair, which were considered less satisfied. After dichotomization, 57% (1042 of 1824) of patients were classified as more satisfied with the treatment results.

RESULTS

The following variables were independently associated with satisfaction with treatment results, with an area under the curve of 0.82 (95% confidence interval 0.80 to 0.84) (arranged from the largest to the smallest standardized odds ratio [SOR]): greater decrease in pain during physical load (standardized odds ratio 2.52 [95% CI 2.18 to 2.92]; p < 0.001), patient's positive experience with the explanation of the pros and cons of the treatment (determined with the question: "Have you been explained the pros and cons of the treatment or surgery?") (SOR 1.83 [95% CI 1.41 to 2.38]; p < 0.001), greater improvement in hand function (SOR 1.76 [95% CI 1.54 to 2.01]; p < 0.001), patients' positive experience with the advice for at-home care (determined with the question: "Were you advised by the healthcare providers on how to deal with your illness or complaints in your home situation?") (SOR 1.57 [95% CI 1.21 to 2.04]; p < 0.001), patient's better personal control (determined with the question: "How much control do you feel you have over your illness?") (SOR 1.24 [95% CI 1.1 to 1.40]; p < 0.001), patient's more positive treatment expectations (SOR 1.23 [95% CI 1.04 to 1.46]; p = 0.02), longer expected illness duration by the patient (SOR 1.20 [95% CI 1.04 to 1.37]; p = 0.01), a smaller number of symptoms the patient saw as part of the illness (SOR 0.84 [95% CI 0.72 to 0.97]; p = 0.02), and less concern about the illness the patient experiences (SOR 0.84 [95% CI 0.72 to 0.99]; p = 0.04). For willingness to undergo the treatment again, the following variables were independently associated with an AUC of 0.81 (95% CI 0.78 to 0.83) (arranged from the largest to the smallest standardized OR): patient's positive experience with the information about the pros and cons (determined with the question: "Have you been explained the pros and cons of the treatment or surgery?") (SOR 2.05 [95% CI 1.50 to 2.80]; p < 0.001), greater improvement in hand function (SOR 1.80 [95% CI 1.54 to 2.11]; p < 0.001), greater decrease in pain during physical load (SOR 1.74 [95% CI 1.48 to 2.07]; p < 0.001), patient's positive experience with the advice for at home (determined with the question: "Were you advised by the healthcare providers on how to deal with your illness or complaints in your home situation?") (SOR 1.52 [95% CI 1.11 to 2.07]; p = 0.01), patient's positive experience with shared decision-making (determined with the question: "Did you decide together with the care providers which care or treatment you will receive?") (SOR 1.45 [95% CI 1.06 to 1.99]; p = 0.02), higher credibility the patient attributes to the treatment (SOR 1.44 [95% CI 1.20 to 1.73]; p < 0.001), longer symptom duration (SOR 1.27 [95% CI 1.09 to 1.52]; p < 0.01), and patient's better understanding of the condition (SOR 1.17 [95% CI 1.01 to 1.34]; p = 0.03).

CONCLUSION

Our findings suggest that to directly improve satisfaction with treatment results, clinicians might seek to: (1) improve the patient's experience with healthcare delivery, (2) try to influence illness perception, and (3) boost treatment expectations and credibility. Future research should confirm whether these suggestions are valid and perhaps also investigate whether satisfaction with treatment results can be predicted (instead of explained, as was done in this study). Such prediction models, as well as other decision support tools that investigate patient-specific needs, may influence experience with healthcare delivery, expectations, or illness perceptions, which in turn may improve satisfaction with treatment results.

Test-retest Reliability and Construct Validity of the Satisfaction with Treatment Result Questionnaire in Patients with Hand and Wrist Conditions: A Prospective Study

BACKGROUND

A patient's satisfaction with a treatment result is an important outcome domain as clinicians increasingly focus on patient-centered, value-based healthcare. However, to our knowledge, there are no validated satisfaction metrics focusing on treatment results for hand and wrist conditions.

QUESTIONS/PURPOSES

Among patients who were treated for hand and wrist conditions, we asked: (1) What is the test-retest reliability of the Satisfaction with Treatment Result Questionnaire? (2) What is the construct validity of that outcomes tool?

METHODS

This was a prospective study using two samples: a test-retest reliability sample and a construct validity sample. For the test-retest sample, data collection took place between February 2020 and May 2020, and we included 174 patients at the end of their treatment with complete baseline data that included both the primary test and the retest. Test-retest reliability was evaluated with a mean time difference of 7.2 ± 1.6 days. For the construct validity sample, data collection took place between January 2012 and May 2020. We included 3742 patients who completed the Satisfaction with Treatment Result Questionnaire, VAS, and the Net Promotor Score (NPS) at 3 months. Construct validity was evaluated using hypothesis testing in which we correlated the patients' level of satisfaction to the willingness to undergo the treatment again, VAS scores, and the NPS. We performed additional hypothesis testing on 2306 patients who also completed the Michigan Hand Outcomes Questionnaire (MHQ). Satisfaction with the treatment result was measured as the patients' level of satisfaction on a 5-point Likert scale and their willingness to undergo the treatment again under similar circumstances.

RESULTS

We found high reliability for level of satisfaction measured on Likert scale (intraclass correlation coefficient 0.86 [95% CI 0.81 to 0.89]) and almost-perfect agreement for both level of satisfaction measured on the Likert scale (weighted kappa 0.86 [95% CI 0.80 to 0.91]) and willingness to undergo the treatment again (kappa 0.81 [95% CI 0.70 to 0.92]) of the Satisfaction with Treatment Result Questionnaire. Construct validity was good to excellent as seven of the eight hypotheses were confirmed. In the confirmed hypotheses, there was a moderate-to-strong correlation with VAS pain, VAS function, NPS, MHQ pain, and MHQ general hand function (Spearman rho ranged from 0.43 to 0.67; all p < 0.001) and a strong to very strong correlation with VAS satisfaction and MHQ satisfaction (Spearman rho 0.73 and 0.71; both p < 0.001). The rejected hypothesis indicated only a moderate correlation between the level of satisfaction on a 5-point Likert scale and the willingness to undergo the treatment again under similar circumstances (Spearman rho 0.44; p < 0.001).

CONCLUSION

The Satisfaction with Treatment Result Questionnaire has good-to-excellent construct validity and very high test-retest reliability in patients with hand and wrist conditions.

CLINICAL RELEVANCE

This questionnaire can be used to reliably and validly measure satisfaction with treatment result in striving for patient-centered care and value-based healthcare. Future research should investigate predictors of variation in satisfaction with treatment results.

The Effect of Bolus Vitamin D3 Supplementation on Distal Radius Fracture Healing: A Randomized Controlled Trial Using HR-pQCT

Vitamin D is an important factor in bone metabolism. Animal studies have shown a positive effect of vitamin D₃ supplementation on fracture healing, but evidence from clinical trials is inconclusive. A randomized controlled trial was performed to assess the effects of vitamin D₃ supplementation on fracture healing using HR-pQCT-based outcome parameters. Thirty-two postmenopausal women with a conservatively treated distal radius fracture were included within 2 weeks postfracture and randomized to a low-dose (N = 10) and a high-dose (N = 11) vitamin D intervention group receiving a 6-week bolus dose, equivalent to 700 and 1800 IU vitamin D₃ supplementation per day, respectively, in addition to a control group (N = 11) receiving no supplementation. After the baseline visit 1-2 weeks postfracture, follow-up visits were scheduled at 3-4, 6-8, and 12 weeks postfracture. At each visit, HR-pQCT scans of the fractured radius were performed. Cortical and trabecular bone density and microarchitectural parameters and microfinite element analysis-derived torsion, compression, and bending stiffness were assessed. Additionally, serum markers of bone resorption (CTX) and bone formation (PINP) were measured. Baseline serum levels of 25OHD₃ were <50 nmol/L in 33% of all participants and <75 nmol/L in 70%. Compared with the control group, high-dose vitamin D₃ supplementation resulted in a decreased trabecular number (regression coefficient β: -0.22; p < 0.01) and lower compression stiffness (B: -3.63; p < 0.05, together with an increase in the bone resorption marker CTX (B: 0.062; p < 0.05). No statistically significant differences were observed between the control and low-dose intervention group. In conclusion, the bolus equivalent of 700 U/day vitamin D₃ supplementation in a Western postmenopausal population does not improve distal radius fracture healing and an equivalent dose of 1800 IU/day may be detrimental in restoring bone stiffness during the first 12 weeks of fracture healing. © 2021 The Authors.

Measurement Properties of Outcome Measures Used to Assess Physical Impairments in Patients After Distal Radius Fracture: A Systematic Review

OBJECTIVES

Individuals with distal radius fractures (DRF) may experience difficulty with gripping an object, painful wrist movements, sensorimotor difficulties, and swelling around the wrist and hand. A comprehensive review of the existing evidence concerning the measurement properties of common physical impairment measures can provide a valuable resource to guide hand therapy practice while managing DRF. The primary objective was to locate and assess the quality of literature on the measurement properties for the measures of physical impairment used in individuals with DRF.

METHODS

Two reviewers searched PubMed, CINAHL, and EMBASE. A combination of DRF, measurement properties, and physical impairments were used as keywords, and articles were independently assessed using the Consensus-Based Standards for the Selection of Health Measurement Instruments critical appraisal tool. Primary studies were included if they examined at least 1 of the following: reliability, validity, responsiveness, or indices of true and meaningful changes for measures of physical impairment in the DRF sample. A total of 19 articles were included in this review. The quality of the studies ranged from 46% to 92%. This review suggests that measures such as assessment of grip strength and supination and pronation range of motion (ROM), using various goniometric devices, showed good intrarater and interrater reliability, construct validity, and responsiveness in individuals with DRF.

CONCLUSION

Acceptable reliability and responsiveness were reported in grip and wrist ROM assessments for measuring changes in wrist and hand function after DRF; however, wrist ROM assessed using traditional goniometric techniques were less reliable in individuals with DRF.

IMPACT

This study provides insight into which objective tools might be better suited for measuring outcomes related to DRF.

Effect of Ulnar-Based Orthotics and Strengthening Exercises on Subjects With Ulnar Wrist Pain

CONTEXT

In comparison with the published research on the surgical management of ulnar wrist pain, fewer studies that discuss the nonsurgical management of ulnar wrist pain exist.

OBJECTIVE

The purpose of this pilot study was to investigate the effect of ulnar-based wrist orthotics and strengthening exercises on subjects with ulnar wrist pain.

STUDY DESIGN

Prospective randomized controlled pilot study.

SETTING

Research laboratory.

PARTICIPANTS

Thirty subjects with acute and subacute ulnar wrist pain and age ranging from 18 to 53.

INTERVENTIONS

Participants were randomized to receive either ulnar-based orthotics, ulnar-based orthotics plus strengthening exercises, or placebo intervention.

MAIN OUTCOME MEASURES

The authors measured pain and function using the Patient-Rated Wrist Evaluation questionnaire, and grip strength using the JAMAR dynamometer, at baseline and at 2- and 4-week postrandomization. A mixed analysis of variance modeling was used to investigate the effect of the intervention over time.

RESULTS

There were statistically significant differences between the 2 intervention groups and the control group regarding improvement in pain, function, and strength, whereas there were no statistically significant differences between the 2 intervention groups over the 3 measurement occasions regarding the outcome measures.

CONCLUSION

Based on the results, orthotics intervention is as effective as orthotics plus strengthening exercises in improving pain, function, and grip strength in subjects with ulnar wrist pain.

LEVEL OF EVIDENCE

Therapy, level 2b individual Randomized Controlled Trial.

Linking physical therapy outcome measures to the Brief International Classification of Functioning Core Set for Hand Conditions in subjects with ulnar wrist pain

OBJECTIVE

The purpose of this study was to apply the Brief International Classification of Functioning (ICF) Core Set for Hand Conditions to the physical therapy outcome measures, and to evaluate the contribution of these measures to overall health in subjects with ulnar wrist pain.

METHODS

Thirty-five subjects with ulnar wrist pain received a 4-week home-based treatment program including orthotics and strengthening exercises. Investigators measured pain, function, grip strength, and overall health four weeks post-intervention. Regression analysis was used to investigate the effect of these variables on overall health represented by the Short Form (SF-36) questionnaire.

RESULTS

Fifty-three percent of the variability in SF-36 physical health summary scores was explained by the studied variables with grip strength predicting 31% of the variability.

CONCLUSIONS

The Brief ICF Core Set for Hand Conditions can be a useful abridged list of categories relevant to functioning and health in subjects with ulnar wrist pain.

Long-term functional outcome of distal radius fractures is associated with early post-fracture bone stiffness of the fracture region: An HR-pQCT exploratory study

Identifying determinants of long-term functional outcome after a distal radius fracture is challenging. Previously, we reported on the association between early HR-pQCT measurements and clinical outcome 12 weeks after a conservatively treated distal radius fracture. We extended the follow-up and assessed functional outcome after two years in relation to early HR-pQCT derived bone parameters. HR-pQCT scans of the fracture region were performed in 15 postmenopausal women with a distal radius fracture at 1-2 (baseline), 3-4 weeks and 26 months post-fracture. Additionally, the contralateral distal radius was scanned at baseline. Bone density, micro-architecture parameters and bone stiffness using micro-finite element analysis (μFEA) were evaluated. During all visits, wrist pain and function were assessed using the patient-rated wrist evaluation questionnaire (PRWE), quantifying functional outcome with a score between 0 and 100. Two-year PRWE was associated with torsional and bending stiffness 3-4 weeks post-fracture (R²: 0.49, p = 0.006 and R²: 0.54, p = 0.003, respectively). In contrast, early micro-architecture parameters of the fracture region or contralateral bone parameters did not show any association with long-term outcome. This exploratory study indicates that HR-pQCT with μFEA performed within four weeks after a distal radius fracture captures biomechanical fracture characteristics that are associated with long-term functional outcome and therefore could be a valuable early outcome measure in clinical trials and clinical practice.

The effectiveness of adding a scapular exercise programme to physical therapy treatment in patients with distal radius fracture treated conservatively: a randomized controlled trial

OBJECTIVE

To determine the effectiveness of a scapular exercise programme in addition to a physical therapy treatment in patients with distal radius fracture.

DESIGN

A single-blinded randomized controlled trial was conducted.

SETTING

Clinical Hospital San Borja Arriaran, Santiago, Chile.

PARTICIPANTS

A total of 102 patients above 60 years of age with extra-articular distal radius fracture were randomly divided into two groups.

INTERVENTIONS

The control group (n = 51) received a six-week physical therapy treatment; the intervention group (n = 51) received the same treatment plus a scapular exercise programme.

OUTCOME MEASURES

The two groups were assessed at baseline and after the six-week treatment. The arm function was assessed with the disabilities of the arm, shoulder and hand (DASH) questionnaire; secondary outcomes were measured by the patient-rated wrist evaluation (PRWE) questionnaire and visual analogue scale (VAS).

RESULTS

A total of 102 patients, 51 in the control group (40 women; mean age of 65.3 ± 4.8 years) and 51 in the intervention group (42 women; mean age of 67.2 ± 5.4 years), were analysed. At the end of the treatment, the difference between groups for the DASH was 16.7 points (P < 0.001), 1.5 points (P = 0.541) for the PRWE, 0.2 cm (P = 0.484) for the VAS at rest, and 1.7 cm (P < 0.001) for the VAS at movement. All differences were in favour of the intervention group.

CONCLUSION

In the short term, adding a scapular exercise programme provides a significant clinical benefit in arm function and pain relief with movement in patients above 60 years of age with extra-articular distal radius fracture treated conservatively.

Carpal Alignment: A New Method for Assessment

Background  Carpal alignment may be used as a tool to evaluate fracture reduction in patients with distal radius fractures. However, there is little consensus on how to measure and quantify carpal alignment. Purpose  The aim of this study was to compare the inter- and intraobserver variability of a new perpendicular method with the existing method in fractured and unfractured wrists. Additionally, the normal distribution of carpal alignment in unfractured wrists was investigated. Patients and Methods  Carpal alignment was assessed on lateral plain radiographs using two different methods, one described by Ng and McQueen and another newly proposed method, the perpendicular method. Using the perpendicular method, the observer draws one line along the inner rim of the volar cortex of the radius and one perpendicular line to the center of the capitate. The carpus is aligned when the line along the inner rim transects the center of the capitate. Three examiners measured the carpal alignment in 50 patients with nonfractured and 50 patients with fractured distal radius. Intra- and interobserver variability for both methods were determined. Results  The interobserver coefficient for the perpendicular method was 0.98 and that for the Ng method was 0.86. The intraobserver coefficients for three examiners were 0.89, 0.62, and 0.63, respectively, for the Ng method. For the perpendicular method, the intraobserver variability was 0.96, 0.89, and 0.72, respectively. In patients with unfractured wrists, the mean perpendicular to the center of the capitate was 0.25 mm dorsally. Conclusion  The new proposed method is a reproducible method for measuring carpal alignment with a high inter- and intraclass coefficient. Clinical Relevance  This method of measurement allows for a reproducible technique for measuring carpal alignment.

Conservative Treatment of Distal Radius Fractures: A Prospective Descriptive Study

BACKGROUND

Disability of the upper limb is one of the consequences of distal radius fracture (DRF). The outcome of DRF treatment is based on objective clinical variables, as strength or range of movement (ROM); sometimes these variables do not correlate with the functional level of the patient. The principal objective of our study was to assess the repercussion of conservative treatment of DRF on upper limb disability.

METHODS

This is a retrospective review of prospectively collected data. We collected data of 61 nonconsecutive DRFs treated conservatively from July 2007 to August 2008.

RESULTS

Average Disabilities of the Arm, Shoulder and Hand (DASH) score before fracture was 20.8 points; average DASH score after the fracture was 42.6. There was a significant increase in the upper limb disability after 1 year of follow-up in the patients treated conservatively ( P < .001; size effect, 1.06). Average radial inclination, radial tilt, and radial length were 18.18°, 3.35°, and 5.76 mm, respectively. Average ROM for flexion-extension was 100.6° and for pronation-supination 144.0°. ROM for flexion-extension of the unaffected wrist was 128.2° and for pronation-supination 172.4°. We did not find any significant statistical correlation between the increase in disability and the decrease in the ROM ( P > .05). We did not find any significant statistical correlation between the increase in the disability and the worsening in the radiological parameters ( P > .05). Our results confirm the hypothesis that the conservative treatment of DRF produced an increase in the upper limb disability after 1 year of follow-up.

CONCLUSIONS

Our study does not show a correlation between the increase in upper limb disability and the decrease in wrist ROM. Our study did not find a correlation between radiological measures and DASH scores.

The Spanish version of the Patient-Rated Wrist Evaluation outcome measure: cross-cultural adaptation process, reliability, measurement error and construct validity

BACKGROUND

The Patient-Rated Wrist Evaluation (PRWE) is a widely used measure of patient-reported disability and pain related to wrist disorders. We performed cross-cultural adaptation of the PRWE into Spanish (Spain) and assessed reliability and construct validity in patients with distal radius fracture.

METHODS

Adaptation of the English version to Spanish (Spain) was performed using translation/back translation methodology. The measurement properties of the PRWE-Spanish were assessed in a sample of 40 consecutive patients (31 women), mean age 58 (SD 19) years, with extra-articular distal radius fractures treated with closed reduction and cast. The patients completed the PRWE-Spanish and the standard Spanish versions of the 11-item Disabilities of the Arm, Shoulder and Hand (QuickDASH) and EQ-5D questionnaires at baseline (health status before fracture) and at 8, 9, 12, and 13 weeks after treatment. Internal-consistency reliability was assessed with the Cronbach alpha coefficient and test-retest reliability with the intraclass correlation coefficient (ICC) comparing responses at 8 and 9 weeks and responses at 12 and 13 weeks. Cross-sectional precision was analyzed with the Standard Error of the Measurement (SEM). Longitudinal precision for test-retest reliability coefficient was analyzed with the Standard Error of the Measurement difference (SEMdiff) and the Minimal Detectable Change at 90% (MDC₉₀) and 95% (MDC₉₅) confidence levels. For assessing construct validity we hypothesized that the PRWE-Spanish (lower score indicates less disability and pain) would have strong positive correlation with the QuickDASH (lower score indicates less disability) and moderate negative correlation with the EQ-5D Index (higher score indicates better health); Spearman correlation coefficient (r) was used.

RESULTS

For the PRWE total score, Cronbach alpha was 0.98 (SEM = 2.67) at baseline and 0.96 (SEM = 4.37) at 8 weeks. For test-retest reliability ICC was 0.94 (8 and 9 weeks) and 0.96 (12 and 13 weeks) with SEMdiff 7.61 and 6.18 and MDC₉₅ 13.74 and 12.11, respectively. The PRWE-Spanish scores had strong positive correlation with the QuickDASH scores at baseline (r = 0.71) and at 8 weeks (r = 0.79) and moderate negative correlation with the EQ-5D Index (r = -0.44 and r = -0.40, respectively).

CONCLUSIONS

The PRWE-Spanish showed high internal-consistency and test-retest reliability and good construct validity in patients with distal radius fracture.

The Effect of Workers' Compensation on Outcome Measurement Methods after Upper Extremity Surgery: A Systematic Review and Meta-Analysis

BACKGROUND

Patients who receive workers' compensation often display worse surgical results, such as prolonged pain or reduced functional ability. The outcomes of surgery can be assessed using a variety of surveys, assessments, and measurements. It is unknown whether the confounding effect differs based on how results are measured. The aim of this study was to determine whether these variations exist.

METHODS

A search of full-length articles published between January 1, 1995, and December 31, 2015, was conducted using 3 online databases. The authors performed a systematic review and meta-analysis using unique inclusion criteria for each.

RESULTS

A total of 101 articles were included in the systematic review; 62 of them were retained for the meta-analysis. In the systematic review, 70 percent of studies found that patients receiving workers' compensation had significantly worse postoperative results than uncompensated patients, whereas only 42 percent of studies that measured preoperative versus postoperative improvement were influenced by workers' compensation. The meta-analysis found that uncompensated patients were more likely to experience improvement after surgery than patients receiving workers' compensation (summary OR, 3.17; 95 percent CI, 2.47 to 4.08). A subgroup analysis demonstrated that functional measures, such as grip strength or nonunion, were least affected by workers' compensation, compared with other outcome measures such as patient-reported outcomes questionnaires or time off work.

CONCLUSION

Potential bias introduced by workers' compensation can be mitigated by evaluating surgical treatment of work-related upper extremity disorders using preoperative versus postoperative improvement or functional measures.

PRWE application in distal radius fracture: comparison and correlation with established outcomes

OBJECTIVE

The study aimed to evaluate the correlation between the PRWE score with other measurements that are already widely used.

METHODS

This was a prospective, cross-sectional, single-center study. Sixty-eight consecutive patients underwent surgical treatment for distal radius fractures (internal fixation by locked volar plate or transarticular external fixation). They were evaluated independently by PRWE, DASH, VAS range of motion, strength, and radiographic criteria, in one year of follow up. The Mann-Whitney test was used to compare continuous variables and the Spearman correlation to correlate the outcomes of interest.

RESULTS

PRWE correlated significantly with DASH (p < 0.001) and VAS (p < 0.001). There were no significant correlations with other outcome measures.

CONCLUSION

PRWE presents significant moderate correlation only with DASH and VAS. Range of motion, strength, and radiographic criteria do not interfere in the PRWE outcome.

A structured literature synthesis of wrist outcome measures: An evidence-based approach to determine use among common wrist diagnoses

STUDY DESIGN

Structured literature synthesis.

INTRODUCTION

Hand therapists and researchers have numerous options when selecting outcome measures for patients with wrist pathologies. An evidence-based approach to determining which measures are used most often can inform choices.

PURPOSE OF THE STUDY

To describe how frequently outcome measures are used in recent randomized controlled trials of patients with wrist diagnoses. Identifying assessment design and related International Classification of Functioning, Disability and Health (ICF) domains provides additional consideration for selection.

METHODS

Systematic PubMed and Cumulative Index to Nursing and Allied Health Literature searches for the time frame between January 2005 and March 2015 captured measures used in randomized controlled trials researching wrist-specific fractures, ligament injuries, nerve injuries, arthritis/arthroplasty, or stress injuries/wrist pain.

RESULTS

Three most frequent measures used within each diagnostic category are detailed with assessment design described and ICF domain identified. Across diagnoses, grip/pinch strength and Disabilities of Arm, Shoulder and Hand were the most frequently used physical and patient-reported outcome measures, respectively. The Jebsen-Taylor Hand Function Test was the most frequently used performance measure.

DISCUSSION AND CONCLUSIONS

Consideration of the evidence, ICF domains, wrist diagnoses, and assessment design can help hand therapists select the measure most appropriate for use.

Rehabilitation strategies for wrist sensorimotor control impairment: From theory to practice

This clinical review discusses the organization, neuroanatomy, assessment, clinical relevance, and rehabilitation of sensorimotor (SM) control impairment after wrist trauma. The wrist SM control system encompasses complex SM pathways that control normal wrist active range of motion and mediate wrist joint neuromuscular stability for maintaining joint function. Among various known assessment methods of wrist SM control impairment, the active wrist joint position sense test is determined to be a clinically meaningful and responsive measure for wrist SM control impairment after wrist fracture. Wrist trauma may involve significant soft tissue injury (ie, skin, ligament, muscle), which could disrupt the generation and transmission of adequate proprioceptive input from wrist mechanoreceptors, thus leading to significant joint SM impairment. Various clinical examples of wrist trauma (eg, distal radius fracture, scapholunate joint injury) along with known prognostic factors (eg, pain) that may influence wrist SM control impairment recovery are discussed to illustrate this point. This article proposes promising rehabilitation strategies toward restoring wrist joint conscious and unconscious SM control impairments, integrating current research evidence with clinical practice. These strategies require more rigorous evaluation in clinical trials.

Preferences for Shared Decision Making in Older Adult Patients With Orthopedic Hand Conditions

PURPOSE

The practice of medicine is shifting from a paternalistic doctor-patient relationship to a model in which the doctor and patient collaborate to decide optimal treatment. This study aims to determine whether the older orthopedic population desires a shared decision-making approach to care and to identify patient predictors for the preferred type of approach.

METHODS

This cross-sectional investigation enrolled 99 patients, minimum age 65 years, at a tertiary hand specialty practice between March and June 2015. All patients completed the Control Preferences Scale, a validated system that distinguishes among patient preferences for patient-directed, collaborative, or physician-directed decision making. Bivariate and logistic regression analyses assessed associations among demographic data; clinic encounter variables such as familiarity with provider, trauma, diagnosis, and treatment decision; and the primary outcome of Control Preferences Scale preferences.

RESULTS

A total of 81% of patients analyzed preferred a more patient-directed role in decision making; 46% of the total cohort cited a collaborative approach as their most preferred treatment approach. Sixty-seven percent cited the most physician-directed approach as their least preferred model of decision making. In addition, 49% reported that spending more time with their physician to address questions and explain the diagnosis would be most useful when making a health care decision and 73% preferred additional written informational material. Familiarity with the provider was associated with being more likely to prefer a collaborative approach.

CONCLUSIONS

Older adult patients with symptomatic upper-extremity conditions desire more patient-directed roles in treatment decision making. Given the limited amount of reliable information obtained independently outside the office visit, our data suggest that written decision aids offer an approach to shared decision making that is most consistent with the preferences of the older orthopedic patient.

CLINICAL RELEVANCE

This study quantifies older adults' desire to participate in decision making when choosing among treatments for hand conditions.

Are validated outcome measures used in distal radial fractures truly valid? A critical assessment using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist

OBJECTIVES

Patient-reported outcome measures (PROMs) are often used to evaluate the outcome of treatment in patients with distal radial fractures. Which PROM to select is often based on assessment of measurement properties, such as validity and reliability. Measurement properties are assessed in clinimetric studies, and results are often reviewed without considering the methodological quality of these studies. Our aim was to systematically review the methodological quality of clinimetric studies that evaluated measurement properties of PROMs used in patients with distal radial fractures, and to make recommendations for the selection of PROMs based on the level of evidence of each individual measurement property.

METHODS

A systematic literature search was performed in PubMed, EMbase, CINAHL and PsycINFO databases to identify relevant clinimetric studies. Two reviewers independently assessed the methodological quality of the studies on measurement properties, using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist. Level of evidence (strong / moderate / limited / lacking) for each measurement property per PROM was determined by combining the methodological quality and the results of the different clinimetric studies.

RESULTS

In all, 19 out of 1508 identified unique studies were included, in which 12 PROMs were rated. The Patient-rated wrist evaluation (PRWE) and the Disabilities of Arm, Shoulder and Hand questionnaire (DASH) were evaluated on most measurement properties. The evidence for the PRWE is moderate that its reliability, validity (content and hypothesis testing), and responsiveness are good. The evidence is limited that its internal consistency and cross-cultural validity are good, and its measurement error is acceptable. There is no evidence for its structural and criterion validity. The evidence for the DASH is moderate that its responsiveness is good. The evidence is limited that its reliability and the validity on hypothesis testing are good. There is no evidence for the other measurement properties.

CONCLUSION

According to this systematic review, there is, at best, moderate evidence that the responsiveness of the PRWE and DASH are good, as are the reliability and validity of the PRWE. We recommend these PROMs in clinical studies in patients with distal radial fractures; however, more clinimetric studies of higher methodological quality are needed to adequately determine the other measurement properties.Cite this article: Dr Y.

A Unified Approach to Outcomes Assessment for Distal Radius Fractures

Distal radius fractures are one of the most common upper extremity injuries. Currently, outcome assessment after treatment of these injuries varies widely with respect to the measures that are used, timing of assessment, and the end points that are considered. A more consistent approach to outcomes assessment would provide a standard by which to assess treatment options and best practices. In this summary, we review the consensus regarding outcomes assessment after distal radius fractures and propose a systematic approach that integrates performance, patient-reported outcomes, pain, complications, and radiographs.

Assessment Following Distal Radius Fractures: A Comparison of 4 Scoring Systems, Visual Numerical Scales, and Objective Measurements

PURPOSE

To compare 4 recognized upper-limb scoring systems that are regularly used to assess wrist function after injury.

METHODS

We reviewed 116 patients 6 months after volar locking plate fixation for distal radius fractures. Two purely subjective and 2 composite scoring systems composed of both subjective and objective components were compared along with visual numerical scores for pain and function and objective measures of function. Each score was standardized into a scale from 0 to 100.

RESULTS

The distribution of the standardized total scores was statistically significantly different and indicated marked variability between scoring systems and therefore the information provided. Overall, the subjective scoring systems correlated well with each other and with both visual numerical scores for pain and function. However, the composite scores and objective measures of function correlated poorly with the subjective scores including the visual numerical scores.

CONCLUSIONS

Results from wrist scoring systems should be interpreted with caution. It is important to ensure that the component parts of each score are taken into consideration separately because total scores may be misleading.

CLINICAL RELEVANCE

Composite scores may be outdated and should be avoided.

A systematic review of the measurement properties of the patient-rated wrist evaluation

STUDY DESIGN

Systematic review of measurement properties.

OBJECTIVES

To summarize the measurement properties of the Patient-Rated Wrist Evaluation (PRWE) questionnaire.

BACKGROUND

The PRWE is a region-specific outcome measure initially developed for assessing pain and function in individuals with distal radius fracture. However, subsequent research has expanded its use to other wrist/hand conditions. A systematic review of the measurement properties of the PRWE can enhance the understanding of its clinical applicability across different wrist/hand pathologies.

METHODS

The MEDLINE, Embase, and CINAHL databases were searched using predefined search terms. A hand search of the bibliography of the primary studies was performed. Studies assessing at least 1 measurement property of the PRWE, either in the English version or versions in other languages, were included in this review. Two raters performed data extraction and critical appraisal of the primary studies using standardized instruments.

RESULTS

A total of 22 primary studies met the inclusion criteria. The overall quality of the 22 studies ranged from 38% to 88%, with 9 scoring greater than 70%. Agreement between the raters who determined the quality of the studies was 0.75 (unweighted kappa). The measurement properties of the PRWE were summarized for different wrist/hand conditions.

CONCLUSION

The PRWE is reliable, valid, and responsive across many wrist/hand conditions. Future studies should focus on determining values for the minimal detectable change and clinically important differences for the PRWE across different patient populations.

A retrospective cohort investigation of active range of motion within one week of open reduction and internal fixation of distal radius fractures

Distal radius fractures stabilized by open reduction internal fixation (ORIF) have become increasingly common. There is currently no consensus on the optimal time to commence range of motion (ROM) exercises post-ORIF. A retrospective cohort review was conducted over a five-year period to compare wrist and forearm range of motion outcomes and number of therapy sessions between patients who commenced active ROM exercises within the first seven days and from day eight onward following ORIF of distal radius fractures. One hundred and twenty-one patient cases were identified. Clinical data, active ROM at initial and discharge therapy assessments, fracture type, surgical approaches, and number of therapy sessions attended were recorded. One hundred and seven (88.4%) cases had complete datasets. The early active ROM group (n = 37) commenced ROM a mean (SD) of 4.27 (1.8) days post-ORIF. The comparator group (n = 70) commenced ROM exercises 24.3 (13.6) days post-ORIF. No significant differences were identified between groups in ROM at initial or discharge assessments, or therapy sessions attended. The results from this study indicate that patients who commenced active ROM exercises an average of 24 days after surgery achieved comparable ROM outcomes with similar number of therapy sessions to those who commenced ROM exercises within the first week.

Contribution of functional parameters to patient-rated outcomes after surgical treatment of distal radius fractures

PURPOSE

Outcomes of distal radius fractures can be measured radiographically, functionally, or via patient-rated questionnaires, but previous studies report conflicting results regarding the relationship between these outcomes. Our specific aim was to explore the role that functional outcomes have in the score of the Michigan Hand Outcomes Questionnaire (MHQ), a patient-rated hand instrument.

METHODS

We obtained data for 207 patients. Demographic information was collected as part of the MHQ. Function (wrist motion and grip and pinch strength) was assessed 3 and 6 months after fracture fixation. We applied linear regression analysis to determine each item's contribution to the total MHQ score.

RESULTS

After we applied linear regression analysis, we determined that 3 months after fixation, all included factors contributed 37% of the MHQ score. Only the grip strength difference between the injured and uninjured hands was significantly associated, contributing 22% of the MHQ score. Six weeks and 6 months after fixation, all included factors contributed 43% and 34%, respectively, of the MHQ score. No individual factors were significant contributors.

CONCLUSIONS

Measured functional outcomes variables account for less than 40% of the total MHQ score. Identifying the unmeasured factors that make up the additional 60% of the total MHQ score would be beneficial in the continued examination of patient-rated outcomes. Furthermore, the use of multiple outcomes assessment modalities should be considered in any study measuring patient-rated outcomes.

Recommendation for measuring clinical outcome in distal radius fractures: a core set of domains for standardized reporting in clinical practice and research

INTRODUCTION

Lack of standardization of outcome measurement has hampered an evidence-based approach to clinical practice and research.

METHODS

We adopted a process of reviewing evidence on current use of measures and appropriate theoretical frameworks for health and disability to inform a consensus process that was focused on deriving the minimal set of core domains in distal radius fracture.

RESULTS

We agreed on the following seven core recommendations: (1) pain and function were regarded as the primary domains, (2) very brief measures were needed for routine administration in clinical practice, (3) these brief measures could be augmented by additional measures that provide more detail or address additional domains for clinical research, (4) measurement of pain should include measures of both intensity and frequency as core attributes, (5) a numeric pain scale, e.g. visual analogue scale or visual numeric scale or the pain subscale of the patient-reported wrist evaluation (PRWE) questionnaires were identified as reliable, valid and feasible measures to measure these concepts, (6) for function, either the Quick Disability of the arm, shoulder and hand questionnaire or PRWE-function subscale was identified as reliable, valid and feasible measures, and (7) a measure of participation and treatment complications should be considered core outcomes for both clinical practice and research.

CONCLUSION

We used a sound methodological approach to form a comprehensive foundation of content for outcomes in the area of distal radius fractures. We recommend the use of symptom and function as separate domains in the ICF core set in clinical research or practice for patients with wrist fracture. Further research is needed to provide more definitive measurement properties of measures across all domains.

Clinical evaluation of upper limb function: Patient's impairment, disability and health-related quality of life

Musculoskeletal disorders substantially impacts physical activity, mental state, and quality of life (QOL). Generally, comprehensive assessment of upper limb function requires measures of impairment or disability as well as health-related quality of life. A growing number of outcome instrument have been introduced to evaluate upper limb function and disability, and these measures can be categorized as patient- or clinician-based, and as condition specific or general health-related QOL evaluations. The upper limb outcome instruments reviewed in this article assess different aspect of upper limb conditions, and the measures are affected by differences in cultural, psychological, and gender aspect of illness perception and behavior. Therefore, physician should select/interpret the outcome instruments addressing their primary purpose of research. Information about regional instruments for upper limb condition and health-related QOL in upper limb disorder may help us in decision-making for treatment priority or in interpretation of the treatment outcomes.

Outcome measures and their measurement properties for trapeziometacarpal osteoarthritis: a systematic literature review

The objective was to identify all outcome measures used in studies on trapeziometacarpal osteoarthritis (TMC OA) and evaluate their measurement properties. In a two-step systematic literature review, we first identified studies including TMC OA patients and extracted all outcome measures. They were categorized according to the Outcome Measures in Rheumatology (OMERACT) core set for OA including five dimensions: pain, physical function, global assessment, imaging, and quality of life (QoL). Secondly, we retrieved articles on the measurement properties of the identified outcome measures for TMC OA patients. First, 316 articles including 101 different outcome measures were identified, addressing the OMERACT pain and function domains most frequently but under-representing QoL. Second, 12 articles investigating measurement properties of 12 outcome measures were identified. The methodological quality of these studies was poor to fair, implying that based on the literature no recommendations to use any of the outcome measures can yet be made.

To what degree do shoulder outcome instruments reflect patients' psychologic distress?

BACKGROUND

Psychologic distress contributes to symptom severity in patients with several musculoskeletal disorders. While numerous shoulder outcome instruments are used it is unclear whether and to what degree psychologic distress contributes to the scores.

QUESTIONS/PURPOSES

We asked (1) to what degree shoulder outcome instruments reflect patients' psychologic distress, and (2) whether patients who are strongly affected by psychologic distress can be identified.

METHODS

We prospectively evaluated 119 patients with chronic shoulder pain caused by degenerative or inflammatory disorders using the Constant-Murley scale, Simple Shoulder Test (SST), and Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire. To evaluate psychologic distress, we measured depression using the Center for Epidemiologic Studies-Depression (CES-D) scale and pain anxiety using the Pain Anxiety Symptom Scale (PASS). Demographic and clinical parameters, such as pain scores, ROM, and abduction strength, also were measured. We then assessed the relative contributions made by psychologic distress and other clinical parameters to the quantitative ratings of the three shoulder outcome instruments.

RESULTS

Quantitative ratings of shoulder outcome instruments correlated differently with psychologic distress. Constant-Murley scores did not correlate with psychologic measures, whereas SST scores correlated with PASS (r = 0.32) and DASH scores correlated with PASS and CES-D (r = 0.36 and r = 0.32). Psychologic distress contributed to worsening SST and DASH scores but not to Constant-Murley scores. DASH scores were more strongly influenced by pain anxiety and depression than the other two outcome instruments.

CONCLUSIONS

Shoulder outcome measures reflected different psychologic aspects of illness behavior, and the contributions made by psychologic distress to different shoulder outcome instruments apparently differed. Physicians should select and interpret the findings of shoulder outcome instruments properly by considering their psychologic implications.

Cross-cultural adaptation and psychometric testing of the Hindi version of the patient-rated wrist evaluation

The purpose of this study was to perform cross-cultural adaptation and Hindi translation of the patient-rated wrist evaluation (PRWE) and assess psychometric properties of the PRWE-Hindi. Cross-cultural adaptation and Hindi translation of the PRWE was performed using standardized guidelines. Intraclass correlation coefficient (ICC) was used for assessing test-retest reliability, and Cronbach's alpha (CA) was used for assessing the internal consistency of the PRWE-Hindi. Construct validity was assessed by examining the correlations between the PRWE-Hindi and grip strength, wrist range of movements, and self-reported pain and disability. A total of 50 patients with distal radius fracture were recruited and assessed three times (baseline, two to three days later, and four to five weeks later). PRWE-Hindi demonstrated excellent test-rest reliability (ICC=0.81) and internal consistency (CA=0.89). Moderate to low correlations (r<0.7) were observed between the PRWE-Hindi and other measures of pain and disability. Our results indicated that PRWE-Hindi is a reliable and valid tool and can be used in patients with wrist/hand injuries whose primary language is Hindi.

Determinants of patient satisfaction after orthopedic interventions to the hand: a review of the literature

Treatment effectiveness is increasingly evaluated from the patients' perspective. However, the interpretation of satisfaction is complex because the patient's perception of a satisfactory outcome is influenced by numerous factors. The objective of this study was to identify which factors are associated with patient satisfaction after orthopedic interventions to the hand. A literature review was conducted, including studies on determinants of satisfaction with treatment outcome or unspecified overall satisfaction of patients with hand problems. The results indicate that patient satisfaction is determined by multiple factors. There is moderate evidence that pain/symptoms, activities of daily living/function, aesthetics, and embodiment influence patient satisfaction. Furthermore, data indicate a correlation of strength, range of motion, fulfillment of expectations, deformity, workers' compensation, and length of follow-up with satisfaction. Knowledge about these determinants may lead to a more detailed decision-making process, thus contributing to improved treatment outcomes and cost-effectiveness.

Cross-cultural adaptation and validation of the Korean version of the Michigan hand questionnaire

PURPOSE

The Michigan hand questionnaire (MHQ) is increasingly being used and has been adapted cross-culturally in some Western and Asian countries, but the validation process for an Asian translation of MHQ has not been well described. In this study, we translated and adapted the original MHQ cross-culturally to produce a Korean version, and then assessed the validity and reliability of the Korean version of the MHQ.

METHODS

A total of 176 patients with common hand disorders completed the Korean version of the MHQ and the Disabilities of the Arm, Shoulder, and Hand questionnaire. We included the pain score assessed by a visual analog scale during activity, range of motion, measurement of grip strength, and subjective assessment of the functional state by use of Cooney's scale in the validation process.

RESULTS

There were no major linguistic or cultural problems during forward and backward translations of the MHQ, except for a minor change owing to cultural discrepancies in eating, such as the dominant hand using a spoon and chopsticks instead of both hands using a knife and fork. All subscales of the MHQ showed satisfactory internal consistency. The reproducibility test showed no significant difference. The construct validity revealed a moderate to strong correlation between every subscale of the Korean MHQ against DASH disabilities and symptoms. The aesthetic and satisfaction domains, unique domains of the MHQ, had little correlation with the objective measure of the pain visual analog scale, grip strength, motion and subjective functional state.

CONCLUSIONS

The Korean version of MHQ showed satisfactory internal consistency, test-retest reliability, and validity and demonstrated a significant correlation with the patient-based upper extremity questionnaire and clinical assessment. We found the application and evaluation of the instrument to be feasible and understandable among patients in Korea.

Assessing results after distal radius fracture treatment: a comparison of objective and subjective tools

OBJECTIVES

Functional outcomes following distal radius fractures are directly influenced by the choice of outcome assessment instruments used. Our objective was to compare scoring systems in measuring patient functional outcomes and to determine which scoring system compared most favorably with the widely used Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire.

METHODS

In all, 108 patients between May 2004 and November 2006 were treated operatively following distal radius fractures. Follow-up was at 3 months, 6 months, 1 year, and 2 years postsurgery, during which anatomical and functional assessments were performed. Patient outcomes were recorded using DASH, Green and O'Brien system, Gartland and Werley system, and Sarmiento radiological scoring system.

RESULTS

There was a stronger correlation between the Green and O'Brien scoring system and DASH (r = -.54) than Gartland and Werley and DASH (r = .44). The Green and O'Brien scoring system was more demanding so patients rated "excellent" or "good" had better functional outcome than those bearing the same grade in the Gartland and Werley system. Nonetheless, the Green and O'Brien score and Gartland and Werley score showed good correlation with each other (r = .66). The Sarmiento radiological score had no significant correlation with any of the other scoring systems. Significant predictors of the DASH score were function (r = .42), power grip (r = .41), pain (r = .37), and range of motion (r = .28).

CONCLUSION

The Green and O'Brien scoring system correlated most strongly with the DASH score. Radiological scoring (reflecting anatomical deformity) was not significantly correlated with functional outcome. While subjective parameters "pain" and "function" are influenced by psychosocial factors and thus highly variable, it is paramount to include subjective tools in outcome assessment in future studies on wrist fractures.

Measuring wrist and hand function: common scales and checklists

INTRODUCTION

A hand and wrist disorder affects a patient's overall well-being and health-status. One concept serves as the foundation for all further consideration: in order to have confidence in your results when assessing patients with wrist and hand limitations, the clinician and researcher must choose standardised patient-oriented instruments that address the primary aims of the study. In this paper, we assess the quality of reviews published on patient oriented instruments in current use for assessing function of the hand and wrist joint. We highlight features of commonly used scales that improve readers' confidence in the choice and application of these outcome instruments.

METHODS

A literature search (1950-January 2010) was performed using the MESH terms: hand (strength, injuries, joints) and wrist (injuries, joint) combined with outcome and process assessment (questionnaires, outcome assessment, health status indicators, quality of life). Titles and abstracts (n=341) were screened by two reviewers independently. The GRADE approach was used to assess the quality of ten reviews and the inclusion of clinimetric properties were assessed using the COSMIN checklist.

RESULTS

We included three systematic reviews rated moderate to high (2 hand injury instrument reviews and 1 wrist fracture outcome review). Recommendations of use and an overview are provided for the disability of the arm, shoulder and hand questionnaire (DASH), QuickDASH, the Michigan hand questionnaire (MHQ), the patient-rated wrist hand evaluation outcome questionnaire (PRWHE) and the carpal tunnel questionnaire (CTQ) scales with established measurement properties.

CONCLUSIONS

The DASH, a region-specific 30-item questionnaire is the most widely tested instrument in patients with wrist and hand injuries. The MHQ can provide good value to patients with hand injuries. Although, the CTQ is the most sensitive to clinical change, the DASH and MHQ have shown to be sufficiently responsive to outcome studies of carpal tunnel syndrome. The PRWHE has a good construct validity and responsiveness, which is only slightly better than the DASH to assess patients with wrist injuries. As the quality of patient-oriented validation continues to increase then the instruments can be selected more carefully. We will then be able to see that the future orthopaedic care of patients with hand and wrist injuries may also improve.

Locked volar plating for complex distal radius fractures: Patient reported outcomes and satisfaction

Background

Distal radius fractures are common. The increasing prevalence of osteoporosis contributes to frequently complex articular injuries sustained even after low energy falls. The best method of treating complex type C distal radius fractures is debated. Locked volar plating and external fixation are both widely used with good reported results. Measures of success are traditionally based on technical measurements or the perception of the surgeon. Patient reported measures of outcome are increasingly recognised as important markers of surgical success. We report our experience using locked volar plating for complex type C distal radius fractures as well as patient reported measures of success and satisfaction.

Methods

Over a 12 month period we treated 21 patients with type C distal radius fractures using locked volar plating. These patients were followed up for at least 12 months and the outcome was assessed using clinical examination, grip strength measurements, radiographs and Patient Rated Wrist Evaluation (PRWE) scoring.

Results

The 21 patients studied had an average age of 48 years. There were 8 men and 13 women. All of the fractures had united by 3 months. There were no cases of wound infection or tendon injury/irritation. Patients reported low pain scores, good patient rated wrist evaluation scores and high levels of satisfaction.

Conclusions

Locked volar plating for complex distal radius fractures produces good results when assessed using patient reported measures of outcome. Further work should address whether locked volar plating offers superior outcomes and patient satisfaction compared to external fixation.

[Outcome assessment in geriatric trauma]

The number of elderly and old patients with fractures is steadily increasing. Identification of relevant functional deficits and comorbidities is crucial for an efficient treatment strategy and outcome assessment in this patient group. For this reason the integration of a geriatric assessment in every orthopedic traumatology practice seems recommendable. Assessing the outcome of frequent fragility fractures (hip, radius) requires instruments oriented to the International Classification of Functioning, Disability and Health (ICF) which allow analysis of bodily function and structure as well as activity and participation. A combination of disease and body region-specific scores with generic scores seems to be reasonable. It can also be sensible to include instruments for health economic analyses.

Prediction of grip and key pinch strength in 978 healthy subjects

BACKGROUND

Hand strength is an important independent surrogate parameter to assess outcome and risk of morbidity and mortality. This study aimed to determine the predictive power of cofactors and to predict population-based normative grip and pinch strength.

METHODS

A representative population survey was used as the basis for prediction analyses (n = 978). Bivariate relationships between grip/pinch strengths of the dominate hand were explored by means of all relevant mathematical functions to maximize prediction. The resulting best functions were combined into a multivariate regression.

RESULTS

Polynoms (up to the third degree) were the best predictive functions. On the bivariate level, height was best correlated to grip (46.2% explained variance) and pinch strength (37.7% explained variance) in a linear relationship, followed by sex, age, weight, and occupational demand on the hand. Multivariate regression provided predicted values close to the empirical ones explaining 76.6% of the variance for grip strength and 67.7% for pinch strength.

CONCLUSION

The five easy-to-measure cofactors sex, age, body height, categorized occupational demand on the hand, and body weight provide a highly accurate prediction of normative grip and pinch strength.

Outcomes assessment in fracture healing trials: a primer

The measurement of clinical outcomes in trauma research is often problematic in that it is subjective and currently no feasible gold standard evaluation is available. Consequently, observed trial results are partly dependent on which outcome measure is used. Precise and useful estimates of treatment effects can only be obtained when using reliable, valid, and responsive instruments for measuring fracture healing. This overview outlines the concept of the validation of outcome measures and provides a summary of available and frequently used instruments in orthopaedic clinical trials. Outcome instruments can be divided into assessments by the clinician and assessments by the patient. Clinician-assessed measures are frequently used in routine practice but have often not been validated before their use in research. They include clinical and radiographic assessments. In contrast, patient-assessed measures have been designed specifically for investigational purposes and measure health on various domains. Some of them have been validated extensively. Critically evaluating established clinician-based assessments and integrating those found to be valid with patient-assessed outcomes into a composite measure of fracture healing constitute major future challenges.

The use of kinematic and parametric information to highlight lack of movement and compensation in the upper extremities during activities of daily living

A problem that is common to the study of upper limb kinematics and gait analysis is the translation of the evidence from kinematic measurements into easily interpretable information on the status of the patient, such as the amount of compensation or lack of motion. In this study parameters that can be helpful in the rapid and clear identification of limited wrist motion and compensation were derived from kinematic data. A group of six subjects (group A) with no hand impairment, average age 32.5 ys SD 10.7 ys, and another group of five subjects (group B), average age 34.2 ys SD 16.8 ys, having suffered from distal radius fracture were tested during a cyclic activity of daily living. The activity simulated page turning. Thorax, shoulder, elbow and wrist angles were measured during this task using a motion capture system. Corresponding angle ranges were also calculated. The active range of motion (AROM) found for Group B was generally lower than that of Group A, particularly for elbow supination and wrist movements, with wrist flexion/extension statistically smaller for group B (P=0.02). Additional parameters that took into account lack of movements at the wrist and compensation from shoulder elevation, rotation and elbow pronation/supination proved to be more useful at identifying those subjects of group B outside the normative range and can provide clinicians with a rapid and efficient tool that can shorten the analysis process and help make more informed decisions on therapeutic treatments.
