Predictors of wrist function and health status after operative treatment of fractures of the distal radius

A Treatment Algorithm for Free Vascularized Bone Reconstruction in Rare Large Osseous Defects Involving the Wrist

Large bone defects of the distal radius and/or carpus following tumor resection, trauma, or infection are extremely rare. There are few case reports and series in the literature on the reconstruction approaches required in such cases. Therefore, large studies cannot be used to guide the therapeutic decisions of reconstructive plastic and hand surgeons. The objective of this study is to propose a treatment algorithm to predict the functional outcome and quality of life for the different techniques of free vascularized bone reconstruction in the interval between the distal radius, the carpus, and/or the proximal metacarpal. The algorithm was developed based on our own case studies and the few treatment approaches described in the literature. It can be applied to rare cases of massive bone defects in the wrist. The flowchart enables surgeons to develop an individualized reconstruction concept for various intervals of bone defects in the area of the distal radius and proximal metacarpal bones. Ultimately, the treatment algorithm aims to maximize future quality of life (QoL) and function of the distal upper extremity in rare cases of massive wrist-bone defects.

Perioperative Pain Management for Distal Radius Fractures

Distal radius fractures have a high incidence among both young and elderly patients, and in many instances require operative intervention. When operative intervention is employed, adequate pain management is essential to decrease postoperative complications, such as chronic pain and disability, while minimizing the risk of prolonged opioid use and dependence. Strategies to optimize pain management include regional anesthesia, preoperative dosing of medication, multimodal regimens, long-acting selective opioids at the time of surgery, corticosteroids, and non-pharmacologic therapies.

Comparison of Pain Catastrophic Scale and Anxiety in Patients With Boxer's Fracture and Other Types of Hand Fractures

OBJECTIVE

 The Pain Catastrophic Scale (PCS) is generally associated with high and low post-recovery satisfaction and measures the pain perception of patients in the literature. This study aims to evaluate the association of deliberate (as in a fight or anger causing punching a wall) boxer's fractures with catastrophic pain compared to accidental (as in a fall, accidental knocking it against a wall, etc.) fractures and evaluate the effect of anxiety about fracture union and functional recovery on clinical outcomes.

MATERIALS AND METHODS

 A total of 62 male patients with metacarpal fractures, 31 as a result of deliberate punching (1st group) and 31 with metacarpal fractures as a result of an accident (2nd group), who applied to the emergency department or orthopedic clinic with the diagnosis of metacarpal fracture between January 2021 and October 2022, were included in the study. All patients were selected from patients who were followed up with conservative plaster/splint. The PCS scores of the patients were evaluated comparatively with the clinical results measured after at least six weeks.

RESULTS

 The mean age of the patients was 30.8 (18-50) in the 1st group and 34.8 (18-64) in the 2nd Group, and no statistically significant difference was found (p=0.274). While the median PCS score was 10.5 (interquartile range {IQR}: 12.3) for the 1st group, the median PCS score was 17.5 (IQR: 14.5) for the 2nd group, and the PCS score was statistically significantly lower in group 1 (p=0.009). While the median Visual Analogue Scale (VAS) value was 0 (IQR: 0.3) for the 1st group, the median VAS value was 1 (IQR: 2.0) for the 2nd group, and the VAS score was statistically significantly lower in the 1st group (p<0.001). While the median 'quick disabilities of the arm, shoulder, and hand' (Q-DASH) value was 0 (IQR:2.3) for the 1st group, the median Q-DASH value was 3.4 (IQR:6.3) for the 2nd group, and the Q-DASH score was statistically significantly lower in the 1st group (p=0.001). No significant difference was observed between the 1st and 2nd groups in terms of grip strength values (p=0.815).

CONCLUSION

The etiology of patients presenting with a boxer's fracture should be well understood, and if necessary, these patients should be treated multidisciplinary, with psychiatric help. Better satisfaction can be achieved with lower results in patients whose PCS scoring system has lost its eigenvalue.

Are Radiographic Characteristics Associated With Outcome in Surgically Treated Distal Radius Fractures?

PURPOSE

Evidence to date shows that distal radius fracture displacement measured on radiographs does not correlate with patient-reported outcomes. Quantitative 3-dimensional computed tomography (CT) (Q3DCT) potentially captures fracture displacement more accurately. We aimed to assess the independent association between radiographic, CT, and Q3DCT measures of residual displacement and change in disability, quality of life, range of motion (ROM), and grip strength 12 weeks and 1 year after volar plating of intra-articular distal radius fractures.

METHODS

We performed a secondary analysis of data from a prospective multicenter trial. Seventy-one patients underwent volar plating of their AO Foundation/Orthopaedic Trauma Association type B or C distal radius fracture and were available at 12 weeks; 67 (94%) were available at 1 year. We recorded demographics, postoperative periapical radiographs (radial height, ulnarward inclination, ulnar variance, gap, and step off), lateral radiographs (palmar tilt, scapholunate angle, teardrop angle, and anteroposterior distance), postoperative CT scans (gap [coronal, sagittal and axial]) and step off [sagittal and coronal]), and in 3-dimensional models (number of articular fragments, mean fragment articular surface area, 3-dimensional fragment displacement, and gap surface area). Radiographs and CT scans were obtained within 10 working days after fracture fixation. Outcome measures were change in Patient-Rated Wrist Evaluation (PRWE) scores, EuroQol Group 5-Dimension questionnaire (EQ5D) results, grip strength, and composite wrist ROM at 12 weeks and 1 year compared to preinjury level.

RESULTS

At 1 year, greater recovery in PRWE scores was independently associated with older age. Greater recovery in composite ROM at 1 year was associated with injury to the dominant side and less step-off on posteroanterior radiographs.

CONCLUSIONS

Less posteroanterior step-off was associated with a small improvement in composite wrist ROM at 1 year. This should be considered when counseling patients on the risks and benefits of surgical treatment when radiographic and CT measures of displacement fall within the range found in this study, and in older, low-demand patients.

Validity and reliability of a portable handheld dynamometer compared to a fixed isokinetic dynamometer to assess forearm torque strength

To evaluate the effect of treatment on forearm rotation, torque muscle strength can be assessed using an isokinetic device (IKD) or a wrist dynamometer (WD). The aims of this study were 1) to determine concurrent validity and intra- and inter-rater reliability using the WD, and to examine correlations between WD and IKD in different positions; and 2) subsequently, to establish the intermethod reproducibility between WD as a handheld (HHD) or fixed device. We conducted a cross-sectional study in which torque strength was measured in healthy participants by two observers using an IKD and a WD. Study endpoints were concurrent validity (Pearson's r), intra- and inter-rater reliability, intermethod reproducibility (intraclass correlation coefficient: ICC) and measurement error (limits of agreement: LoA). Concurrent validity ranged, in the 2 studies assessing it, from r 0.37 to 0.52 for pronation and from r 0.50 to 0.82 for supination, with wide 95% confidence intervals. ICC for intra-rater reliability for pronation ranged from 0.85 to 0.91 and for supination from 0.91 to 0.95. ICC for inter-rater reliability for pronation ranged from 0.84 to 0.96 and for supination from 0.92 to 0.96. Despite the excellent intra- and inter-rater reliability and intermethod reproducibility for the WD-HHD and fixed WD, validity was low when compared to IKD and wide LoA indicated a high measurement error of approximately 20%. These results suggest that the WD cannot replace the IKD isometric mode for pronation and supination. LEVEL OF EVIDENCE: 2.

A comparison of early fixation of distal radius fractures versus late corrective osteotomy of distal radius malunion

BACKGROUND

Fractures of the distal radius are common. Closed reduction and moulded casting is often the first line treatment. Malunion after casting is not uncommon and can lead to discussion on acute surgical fixation versus delayed corrective osteotomy if symptomatic. However, it is unclear if late surgery will provide similar outcomes as early intervention.

METHODS

We performed a single centre, age matched, case series comparison study, comparing outcomes of patients who had undergone early fixation (ORIF) versus those who had undergone late corrective osteotomy (CO) following distal radius fracture.

RESULTS

Twenty-six patients were available for review, 13 in each group. Fracture patterns were similar. Reviewing CO versus ORIF; patients achieved a mean DASH; 22 versus 18 (P = 0.355), PRWE; 35 versus 26 (P = 0.237), and VAS 2 versus 2 (P = 0.490). Grip strength was significantly better in those who had undergone ORIF; 2% versus -22% (P ≤ 0.001). Range of motion was generally better with primary fixation but of doubtful clinical importance, reviewing CO versus ORIF; Flexion 46° versus 60° (P = 0.045), extension 55° versus 64° (P = 0.137), pronation 73° versus 85° (P = 0.078), supination 84° versus 84° (P = 0.747), flexion/extension arc 101 versus 124 (P = 0.017), ulnar/radial deviation arc 42° versus 59° (P = 0.01), pronation/supination arc 157° versus 168° (P = 0.118). Ulnar variance was significantly improved in the ORIF group; +0.5 mm versus +2 mm in the CO group (P = 0.023). Radial inclination, radial height and volar tilt were not significantly different between either group.

CONCLUSION

Our findings suggest that patient measured outcome of corrective osteotomy is not inferior to early internal fixation.

Outcome Metrics in the Treatment of Distal Radius Fractures in Patients Aged Above 50 Years: A Systematic Review

BACKGROUND

The inclusion of patient-reported outcome measures (PROMs) serves to better quantify aspects of patient outcomes missed with objective measures, including radiographic indices and physical examination findings. We hypothesize that PROMs are inconsistently and heterogeneously captured in the treatment of distal radius fractures.

METHODS

We performed a systematic review following Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines of all level I and II randomized controlled trials (RCTs) of distal radius fracture treatment of any modality for those older than 50 years of age from January 2008 to January 2018. A total of 23 studies were included in the final analysis. The metrics used by each study to assess outcomes were collected, compared, and described.

RESULTS

Physical examination findings and radiographic measures were reported in 70% and 74% of studies, respectively. Patient-reported outcomes measures were used to assess outcomes in 74% of studies. Only the Disabilities of the Arm, Shoulder, and Hand was used in greater than half of the studies (57%). Pain scores were assessed in 39% of studies and complications in only 26%.

CONCLUSIONS

There is substantial heterogeneity and lack of standardization in the collection of both objective outcome measures and PROMs in level I and II RCTs for the treatment of distal radius fractures. The ability to compare between studies or aggregate data among studies is therefore limited. Radiographic and physical examination findings remain frequently reported despite known limitations of these metrics. The routine collection of PROMs after the treatment of distal radius fractures can ensure care is directed toward improving what is most important to patients.

Factors Affecting Functional Recovery After Volar Locking Plate Fixation for Distal Radius Fractures

BACKGROUND

There is still no certainty about factors delaying functional recovery after surgery, although volar locking plate (VLP) fixation is the mainstay of treatment for distal radius fractures (DRFs), and several good postoperative recoveries have been reported. The purpose of this study was to investigate factors affecting functional recovery after VLP fixation for DRF.

METHODS

The subjects included 104 patients (84 females, 20 males, mean age: 63.2 ± 13.8 years) treated with VLP fixation for DRF, who could be followed for 1 year. The Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) score, grip strength, and range of motion of the wrist joint were measured at 3, 6, and 12 months postoperatively, and the primary outcome was the QuickDASH score. A multiple regression analysis adjusted for age and sex was used to analyze factors affecting functional recovery at 12 months.

RESULTS

A multiple regression analysis showed that the factors that significantly influenced the QuickDASH score at 1 year postoperatively were the grip strength ratio to the uninjured side, dominancy of the injured hand, and postoperative ulnar variance, in descending order of involvement. Trauma energy, history of diabetes, fracture type, complications, and range of motion were not included in the model.

CONCLUSIONS

Smaller grip strength, dominant-hand injury, and larger postoperative ulnar variance significantly worsened the QuickDASH score at 1 year postoperatively. In order to achieve satisfactory functional recovery at 1 year after surgery, we confirmed that it is important to surgically achieve smaller postoperative ulnar variance and increase grip strength.

Symptoms of depression and catastrophic thinking attenuate the relationship of pain intensity and magnitude of incapability with fracture severity

OBJECTIVE

The relative association of pain intensity and magnitude of incapability with pathophysiology, accounting for psychological factors, is incompletely understood. Using moderation analysis, we assessed the association of pain intensity and magnitude of incapability (dependent variables) with fracture severity (independent variable) and the influence of symptoms of depression and catastrophic thinking (moderators) at early and later stages of recovery.

METHODS

A cohort of 731 patients recovering from a shoulder, elbow, or wrist fracture, completed self-reported measures of pain intensity, upper extremity capability, symptoms of depression, and catastrophic thinking between 2 and 4 weeks after injury and again between 6 and 9 months after injury. Fracture severity was rated by clinicians, and we used multivariable regression analysis to examine interaction effects of fracture severity, depression, catastrophic thinking, pain intensity, and magnitude of incapability at early and later stages of recovery.

RESULTS

Symptoms of depression and catastrophic thinking attenuate the relationship between pain intensity and fracture severity at earlier and later stages of recovery. Symptoms of depression and catastrophic thinking also attenuate the relationship between the magnitude of incapability and fracture severity, but only at early stages of recovery.

CONCLUSION

The relative divergence of pain intensity and magnitude of incapability from the level of fracture severity due to the moderating effects of unhelpful thinking and distress, signals a benefit to anticipating mental health opportunities during recovery after fracture. Fracture management can incorporate measures of unhelpful thinking and symptoms of distress to better address these opportunities and ensure comprehensive optimization of recovery.

Difficult life events affect lower extremity illness

BACKGROUND

Given the relationship between psychological distress and activity tolerance (capability), a stressful life event might diminish accommodation, increase symptoms, and induce a person to seek specialty care. As a first step to investigate this possibility, this study addressed whether difficult life events are associated with greater activity intolerance and pain intensity.

METHODS

A cohort of 127 patients seeking specialty care for lower extremity symptoms completed questionnaires that inquired about difficult life events within the last 12 months as derived from the Holmes Rahe Life Stress Inventory, and recorded pain intensity on an 11-point ordinal scale, activity tolerance [Patient Reported Outcomes Measurement Information System Physical Function Computer Adaptive Test (CAT)], symptoms of anxiety (GAD-2; 2 item version of the Generalized Anxiety Disorder questionnaire), symptoms of depression (PROMIS Depression CAT), self-efficacy when in pain (Pain Self-Efficacy Questionnaire, 2 question version), and demographics. The treating clinician indicated if the disease was established (e.g. arthritis) or relatively new (e.g. sprain/strain). Bivariate and multivariable analyses sought factors associated with activity intolerance and pain intensity.

RESULTS

Greater activity intolerance was associated with difficult life events in bivariate analyses (t = 2.13, MD = 3.18, 95% C.I. = 0.22-6.13, p = 0.04) and in multivariable analyses that excluded symptoms of depression. Greater pain intensity was not associated with difficult life events, but was associated with surgeon rating of established disease (β = 1.20, 95% C.I. = 0.33-2.08, p < 0.01), greater symptoms of anxiety (MD = 3.35, s = 1.72; ρ = 0.30, p < 0.01), and less education (β =  - 1.06, 95% C.I. =  - 1.94- - 0.18, p = 0.02) (no college degree).

CONCLUSION

When a musculoskeletal specialist identifies less activity tolerance (less capability) than anticipated for a given injury or pathology, they can anticipate a potential difficult life event, and expect alleviation of symptoms and improved capability as the stress is ameliorated with time and support. Specialists can be prepared to direct people to community or professional support if requested.

The Association Between Psychological Factors and Outcomes After Distal Radius Fracture

PURPOSE

The aim of this study was to identify psychological factors associated with pain intensity and disability following distal radius fracture.

METHODS

We prospectively followed 216 adult patients with distal radius fracture for 9 months. Demographics, injury and treatment details, and psychological measures (Hospital Anxiety and Depression Score [HADS], Pain Catastrophizing Scale, Posttraumatic Stress Disorder Checklist-Civilian, Tampa Scale for Kinesiophobia, Illness Perception Questionnaire Brief [IPQB], General Self-Efficacy Scale, and Recovery Locus of Control [RLOC]) were collected at enrollment. Multivariable linear regression was used to identify factors associated with Disabilities of the Arm, Shoulder, and Hand Questionnaire (DASH) and Likert pain scores.

RESULTS

Higher 10-week DASH scores were associated with increased age, the presence of a nerve pathology, increased HADS Depression subscale scores, increased IPQB scores, and lower RLOC scores. Higher 9-month DASH scores were associated with increased age, increased deprivation scores, increased numbers of medical comorbidities, a greater degree of radial shortening, increased HADS Depression subscale scores, and lower RLOC scores. A higher 10-week pain score was associated with increased deprivation and IPQB scores. A higher pain score at 9 months was associated with an increased number of medical comorbidities.

CONCLUSIONS

Psychosocial factors measured early after fracture are associated with pain and disability up to 9 months after distal radius fracture. Illness perception is a potentially modifiable psychological construct not previously studied in hand conditions. It may provide a suitable target for psychological interventions that could enhance recovery.

Can Generic Outcome Questionnaires Replace QuickDASH in Monitoring Clinical Outcome Following Surgical Treatment of Distal Radius Fractures?

PURPOSE

In contrast to region-specific patient-reported outcome measures (PROMs), generic PROMs can be argued to have an added benefit of enabling cost-utility analyses and allowing for comparisons to be made across different conditions. The aim of this study was to assess the responsiveness and strength of the association between region-specific and generic PROMs in patients treated operatively for a displaced intra-articular distal radius fracture.

METHODS

Over a 4-year period, 166 patients aged 18-70 years with a displaced intra-articular fracture of the distal radius were treated with either a volar locking plate or external fixation augmented by K-wires and followed-up prospectively for 2 years. The main outcome measure was the Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) score, but EuroQol-5D (EQ-5D) and 36-Item Short Form Survey (SF-36) were also employed. The associations between the QuickDASH score and EQ-5D and between the QuickDASH score and SF-36 were assessed using a linear mixed model.

RESULTS

There was a significant positive association between the QuickDASH score and EQ-5D and between the QuickDASH score and SF-36 throughout the follow-up period, although wide dispersion existed for the outcome measures at an individual level. However, the association between the QuickDASH score and SF-36 was significantly weaker at 6 weeks and 3 months than that at baseline, indicating that EQ-5D more closely mirrors changes in the QuickDASH score in the early postoperative period.

CONCLUSIONS

The study demonstrates that the QuickDASH score and EQ-5D correlate well on a group level, but large individual variations exist. The SF-36 had decreased sensitivity for the changes in the QuickDASH score at 6 weeks and 3 months.

CLINICAL RELEVANCE

Our findings indicate that generic PROMs cannot fully replace the region-specific QuickDASH score when evaluating the outcomes of distal radius fractures.

Early Outcomes of Scapholunate Injuries With Concomitant Distal Radius Fractures

Background: There is limited literature regarding the treatment of concomitant scapholunate ligament (SL) injuries in acute distal radius fractures (DRFs). We hypothesized that surgical treatment of SL injuries in adult patients with DRFs leads to improved functional outcomes. Methods: A retrospective review was made of 42 adult patients who underwent surgical treatment of a DRF with a SL injury between 2005 and 2013. In all, 39 of the 42 patients sustained an intra-articular DRF (AO B or C). SL injury was diagnosed by SL diastasis > 3 mm on posteroanterior (PA) radiographs, magnetic resonance imaging, or with wrist arthroscopy. Patients were divided into 3 groups: 23 had a SL repair and were treated within 21 days of injury (acute), 8 underwent SL repair greater than 21 days from injury (subacute/chronic), and 11 did not undergo repair (non-operative). Median overall time to clinical follow-up was 5.1 years. Mayo Wrist Scores (MWS) and Disabilities of the Arm, Shoulder and Hand (DASH) scores were used to evaluate functional outcome. Results: Clinical outcomes measured by the MWS at final follow-up (6 months-12 years) showed no significant differences between the 3 groups. Of patients treated acutely, 17.3% had good to excellent MWS. MWS at 1-year follow-up was 68.4, 70, and 64 in the acute, subacute/chronic, and non-operative groups, respectively. DASH scores were 16.7, 14.3, and 11.8 in the acute, subacute/chronic, and nonoperative groups, respectively, at a mean of 7.8 years. Conclusions: At mid-term follow-up, all 3 treatment groups had similar DASH scores to the general population. There were no statistical functional differences between any of the groups based upon MWS or DASH scores.

A comparison of six outcome measures across the recovery period after distal radius fixation-Which to use and when?

PURPOSE

Many standardized outcome measures exist to measure recovery after surgical fixation of distal radius fractures, however, choosing the optimal instrument is difficult. We evaluated responsiveness, ceiling/floor effects, and criterion validity over multiple time intervals across a 2-year follow-up period for six commonly used instruments.

METHODS

A total of 259 patients who received open reduction and internal fixation for distal radius fractures between 2012 and 2015 were recruited. Patients were administered the Patient-Rated Wrist Evaluation (PRWE), Shortened Disabilities of the Arm, Shoulder and Hand questionnaire (QuickDASH), Green and O'Brien score (Cooney modification) (CGNO), Gartland and Werley score (Sarmiento modification) (SGNW), flexion-extension arc (FEArc), and grip fraction test (GripFrac) at 1.5, 3, 6, 12, and 24 months postoperatively. Responsiveness was evaluated by calculating standardized response means (SRM) and Cohen's d effect sizes (ES), and by correlating each instrument's change scores against those of QuickDASH and PRWE, which were also used as external comparators to assess criterion validity. Ceiling/floor effects were calculated for all measures at each time point.

RESULTS

SRM (1.5-24 months) were 1.81, 1.77, 1.43, 1.16, 2.23, 2.45 and ES (1.5-24 months) were 1.81, 1.82, 1.95, 1.31, 1.99 and 2.90 for QuickDASH, PRWE, CGNO, SGNW, FEArc, and GripFrac respectively. Spearman correlation coefficients against QuickDASH at 24 months were: 0.809, 0.248, 0.563, 0.285, and 0.318 for PRWE, CGNO, SGNW, FEArc, and GripFrac respectively. Significant (>15% of patients reaching maximum score) ceiling effects were observed before 6 months for PRWE and SGNW.

CONCLUSIONS

Our evidence supports the use of QuickDASH, PRWE, FEArc and GripFrac up to 6 months postsurgery, and QuickDASH and PRWE after 6 months.

Outcome Measurement for Distal Radius Fractures

Distal radius fractures (DRFs) are among the most common upper extremity injuries. Multiple medical conditions now are evaluated by standardized outcome sets that enable comparability. Recent international working groups have provided consensus statements for outcomes measurement after DRFs. These statements emphasized the growing importance of patient-reported outcome measures as well as traditional measures, including pain assessment, radiographic alignment, performance, and assessment of complications. A standardized instrument and timeline for measuring outcomes following DRFs offers clinicians, researchers, and health care economists a powerful tool. This article reviews the current evidence and provides recommendations for a DRF standardized outcome set.

Modifiable Factors Associated With Chronic Pain 1 Year After Operative Management of Distal Radius Fractures: A Secondary Analysis of a Randomized Clinical Trial

IMPORTANCE

Despite appropriate treatment, many patients who sustain distal radius fractures (DRFs) report persistent wrist pain. Chronic musculoskeletal pain is among the leading health problems in the elderly population associated with significant personal and societal burden.

OBJECTIVE

To identify modifiable preoperative factors that are significantly associated with developing chronic pain.

DESIGN, SETTING, AND PARTICIPANTS

This is a secondary analysis of the Wrist and Radius Injury Surgical Trial (WRIST), a randomized multicenter clinical trial of 24 study sites in the United States, Canada, and Singapore that enrolled patients from April 10, 2012, to December 31, 2016. Adults older than 60 years who sustained closed extra-articular DRFs, were treated operatively, and completed 12-month Michigan Hand Outcomes Questionnaires (MHQs) were included in this study. Analysis was conducted from September to December 2019.

INTERVENTIONS

Volar locking plate internal fixation, external fixation, or percutaneous pinning.

MAIN OUTCOMES AND MEASURES

12-month MHQ pain domain score. Inverse probability weighted logistic regression was used to identify factors associated with of chronic pain.

RESULTS

A total of 146 patients with DRF who were treated operatively and had 12-month MHQ scores met inclusion criteria. The mean (SD) patient age was 68.9 (7.2) years, 128 (87.6%) were women, and 93 (63.7%) were retired. Chronic pain was present in 87 patients (59.6%) and absent in 59 patients (40.4%) at 1-year follow-up. A 1-week delay in surgery was associated with more than triple the odds of developing chronic pain (odds ratio [OR], 3.65; 95% CI, 1.48-9.00), and each 10-point increase in preoperative pain was associated with a 17% increase in the odds of experiencing chronic pain (OR, 1.17; 95% CI, 1.02-1.34). Internal fixation was associated with decreased odds of developing chronic pain compared with the other 2 procedures (OR, 0.29; 95% CI, 0.10-0.90).

CONCLUSIONS AND RELEVANCE

In this study, preoperative pain, time to surgery, and procedure type were modifiable factors associated with chronic pain 1 year after DRF treated with surgery. Adequate pain control in patients with acute DRFs even before definitive surgical management and earlier fixation for patients requiring surgery may decrease the risk of developing chronic pain. Internal fixation may decrease the risk of chronic pain after DRF surgery, compared with percutaneous pinning or external fixation.

Using the QuickDASH to Model Clinical Recovery Trajectory After Operative Management of Distal Radius Fracture

Purpose

There is a paucity of literature examining the trajectory of meaningful clinical improvement after distal radius fracture (DRF) fixation. We sought to answer the following questions: (1) When do patients meet the minimum clinically important difference (MCID) in the Quick-Disabilities in Arm, Shoulder, and Hand questionnaire (QuickDASH) score change after DRF fixation? (2) What gains in terms of number of MCIDs achieved (as measured by QuickDASH) do patients make as they recover from DRF fixation? (3) What patient and injury factors are characteristic of patients who meet or do not meet the average recovery trajectory?

Methods

We performed a retrospective review of an institutional database of DRF patients treated with operative fixation. The change in QuickDASH scores from before surgery to approximate follow-up intervals of 0 to 2 months, 3 to 6 months, and a minimum of 9 of 12 months was assessed, in which a delta of 14 reflected the MCID. The change in QuickDASH score from before surgery to each follow-up interval was divided by 14 to determine the number of MCIDs, representing appreciable clinical improvement. Patient characteristics were compared between those who did and did not reach average levels of clinical improvement.

Results

The study included 173 patients. Mean QuickDASH score before surgery was 74 (SD, 19; range, 0-100). After surgery, this improved to 50 (SD, 24; range, 0-100) by 0 to 2 months, 22 (SD, 22; range, 0-98) by 3 to 6 months, and 9.8 (SD, 15; range, 0-75) by a minimum of 9 to 12 months. Overall, 96% of patients reached the MCID by 1 year. Mean cumulative number of MCIDs achieved (ie, number of 14-point decreases in QuickDASH score) at each interval was 1.57, 3.64, and 4.43, respectively. Assuming 4.43 represents maximum average improvement at 1 year, patients achieved 35% (1.57 of 4.43) of recovery from 0 to 2 months after surgery and 82% (3.64 of 4.43) of recovery by 3 to 6 months after surgery. There appeared to be no difference in terms of age, sex, or body mass index with respect to these findings.

Conclusions

Overall, 96% of patients undergoing DRF fixation will achieve one QuickDASH MCID by 1 year after surgery. Patients achieved over 80% of total expected functional improvement by 3 to 6 months after surgery, which appeared to be irrespective of age, sex, or body mass index.

How Many Screws Are Needed for Reliable Stability of Extra-articular Nonosteoporotic Distal Radius Fractures Fixed with Volar Locking Plates?

Background

We hypothesized that volar locking pate fixation using a minimum number of screws-four in the distal row and two in the shaft of the plate-will provide sufficient stability for unstable extra-articular fractures of the distal radius. We aimed to compare the biomechanical properties of different numbers and locations of screws in volar locking plate fixation and describe the clinical and radiological outcome of plate fixation using a minimum number of screws for distal radius fractures.

Methods

We divided 48 artificial radius fracture bones into four groups (group A-D) based on the number and location of screws used for fixation with volar locking plates. The artificial bone models were subjected to axial compression and volar bending load with a force of 250 N and 80 N, respectively, for 1,000 cycles at a frequency of 1 Hz. We also retrospectively reviewed 42 patients with unstable, extra-articular, distal radius fractures who were treated with volar locking plate fixation using a minimum number of screws.

Results

Group A (seven distal screws and three proximal screws) had the highest mean stiffness: 303.7 N/mm under axial compression and 61.1 N/mm under volar bending. Compared with group A, group D (four screws in the distal part and two screws in the shaft) showed significantly lower stiffness; therefore, group D was considered inferior in terms of stability. However, in the fatigue test, neither deformation of the metal plate nor detachment or breakage of the metal screws was observed in all groups. In the clinical study, all fractures united without displacement and satisfactory clinical outcome was obtained.

Conclusions

In the dorsally comminuted, extra-articular, nonosteoporotic distal radius fractures, the minimum number of screws-four in the distal row and two in the shaft-in volar locking plate fixation can provide sufficient stability. Further biomechanical studies involving osteoporotic bone will be necessary to confirm the results because volar plate fixation is most commonly used in patients with osteoporosis.

What Is the Effect of Vitamin C on Finger Stiffness After Distal Radius Fracture? A Double-blind, Placebo-controlled Randomized Trial

BACKGROUND

It is proposed that vitamin C administration can reduce disproportionate pain and stiffness after distal radius fracture; however, randomized trials that tested this hypothesis have had inconsistent results.

QUESTIONS/PURPOSES

(1) Is administering vitamin C after distal radius fracture associated with better ROM, patient-reported upper extremity function, and pain scores? (2) What factors are associated with post-fracture finger stiffness and worse upper extremity function?

METHODS

This is a double-blind, randomized, placebo-controlled, noncrossover study. Between August 2014 and July 2017, we approached 204 consecutive patients, of which 195 were eligible, and 134 chose to participate. Participants were randomized to receive once-daily 500 mg vitamin C (67 participants) or placebo (67 participants) within 2 weeks after distal radius fracture. All patients received usual care at the discretion of their surgeon. The mean age of participants was 49 ± 17 years, 99 patients (74%) were women, and 83 (62%) were treated nonoperatively. The primary outcome was the distance between the fingertip and distal palmar crease 6 weeks after fracture. This measure is easy to obtain and previously has been shown to correlate with aggregate ROM of all finger joints. The secondary outcomes were total active finger motion, total active thumb motion, upper extremity-specific limitations, and pain intensity.An a priori power analysis suggested 126 patients would provide 80% power to detect a difference of 2 cm (SD 4.0) fingertip distance to palmar crease with α set at 0.05 using a two-tailed Student's t-test. Accounting for 5% lost to followup, we included 134 patients.All analyses were intention-to-treat. Ten participants of the intervention group and five of the placebo group were lost to followup. Their missing data were addressed by multiple imputation, after which we performed linear regression analysis for our outcome variables.

RESULTS

Administration of vitamin C was not associated with ROM, function, or pain scores at 6 weeks (distance to palmar crease: β -0.23; 95% CI -1.7 to 1.2; p = 0.754; finger ROM: β 4.9; 95% CI, -40 to 50; p = 0.829; thumb ROM: β 0.98; 95% CI, -18 to 20; p = 0.918, Patient-Reported Outcomes Measurement Information System [PROMIS] score: β 0.32; 95% CI, -2.6 to 3.2; p = 0.828; pain score: β -0.62; 95% CI, -0.62 to 0.89; p = 0.729) nor at 6 months (PROMIS score: β -0.21; 95% CI, -3.7 to 3.3; p = 0.904; pain score: β 0.31; 95% CI, -0.74 to 1.4; p = 0.559). At 6 weeks, we found that more finger stiffness was mildly associated with greater age (β -1.5; 95% CI, -2.8 to -0.083; p = 0.038). Thumb stiffness was mildly associated with greater age (β -0.72; 95% CI, -1.3 to -0.18; p = 0.009) and strongly associated with operative treatment (β -32; 95% CI, -50 to -13; p = 0.001). Greater pain interference was modestly associated with greater functional limitations at 6 weeks (β -0.32; 95% CI, -0.52 to -0.12; p = 0.002) and 6 months (β -0.36; 95% CI, -0.60 to -0.11; p = 0.004).

CONCLUSIONS

Vitamin C does not seem to facilitate recovery after distal radius fracture, but amelioration of maladaptation to nociception (pain interference) merits greater attention.

Tibial nailing using a suprapatellar rather than an infrapatellar approach significantly reduces anterior knee pain postoperatively: a multicentre clinical trial

AIMS

The aim of this study was to compare the incidence of anterior knee pain after antegrade tibial nailing using suprapatellar and infrapatellar surgical approaches.

PATIENTS AND METHODS

A total of 95 patients with a tibial fracture requiring an intramedullary nail were randomized to treatment using a supra- or infrapatellar approach. Anterior knee pain was assessed at four and six months, and one year postoperatively, using the Aberdeen Weightbearing Test - Knee (AWT-K) score and a visual analogue scale (VAS) score for pain. The AWT-K is an objective patient-reported outcome measure that uses weight transmitted through the knee when kneeling as a surrogate for anterior knee pain.

RESULTS

A total of 53 patients were randomized to a suprapatellar approach and 42 to an infrapatellar approach. AWT-K results showed a greater mean proportion of weight transmitted through the injured leg compared with the uninjured leg when kneeling in the suprapatellar group compared with the infrapatellar group at all timepoints at all follow-up visits. This reached significance at four months for all timepoints except 30 seconds. It also reached significance at six months at 0 seconds, and for one year at 60 seconds.

CONCLUSION

The suprapatellar surgical approach for antegrade tibial nailing is associated with less anterior knee pain postoperatively compared with the infrapatellar approach Cite this article: Bone Joint J 2019;101-B:1138-1143.

The Aberdeen Weight-Bearing Test (Knee): a new objective test for anterior knee discomfort

Purpose

We present the Aberdeen Weight-Bearing Test (Knee), an objective test specific for anterior knee discomfort assessed via load bearing. We assess its validity by performing it on normal subjects with no knee symptoms and subjects who had undergone anterograde tibial nailing.

Methods

Two scales are placed parallel on the floor with the dials concealed from the subject. The subject then kneels with one knee on each scale. The weight through each knee is recorded at 0, 15, 30, 45, and 60 s. The proportion of total body weight on each leg at each timepoint is calculated, and a ratio calculated from the values. A value of 1 equates to equal weight on each leg. The test was performed on 53 normal subjects and 38 subjects who had undergone tibial nailing.

Results

In the normal group, no significant difference in mean ratio of weight distribution (left:right) was seen at any timepoint (mean ratio range = 0.98–0.99, p value range = 0.18–0.64). In the tibial nail group, a difference was observed in mean ratio of weight distribution (injured:uninjured) favouring the uninjured leg, reaching significance at 0, 15, 30, and 45 s (mean ratio range = 0.88–0.94, p value range = 0.01–0.02). At 60 s, the mean ratio was 0.93 (p = 0.09).

Conclusion

The Aberdeen Weight-Bearing Test (Knee) is an objective, easily reproducible, specific test for anterior knee discomfort. It produces different results in individuals who have undergone anterograde tibial nailing compared to individuals with no knee symptoms.

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.

Biologic plating of unstable distal radial fractures

Background

Volar locking plating through the flexor carpi radialis is a well-established technique for treating unstable distal radial fractures, with few reported complications. In certain circumstances, including metaphyseal comminuted fractures, bridge plating through a pronator quadratus (PQ)-sparing approach may be required to preserve the soft tissue envelope. This study describes our prospective experience with bridge plating through indirect reduction.

Methods

Thirty-three wrists (four 23A2, six 23A3, 15 23C1, and eight 23C2) underwent bridge plating through a PQ-sparing approach with indirect reduction from June 2006 to December 2010. Mean patient age was 56.8 years (range, 25–83 years), and the mean follow-up period was 47.5 months (range, 36–84 months). Changes in radiologic parameters (volar tilt, radial inclination, radial length, and ulnar variance) were analyzed, and functional results at final follow-up were evaluated by measuring the Modified Mayo Wrist Score (MMWS) and Modified Gartland-Werley Score (MGWS).

Results

All wrists achieved bone healing without significant complications after a single operation. At final follow-up, radial length was restored from an average of 3.7 mm to 11.0 mm, as were radial inclination, from 16.4° to 22.5°, and volar tilt, from − 9.1° to 5.5°. However, radial length was overcorrected in three wrists, and two experienced residual dorsal tilt. Excellent and good results on the MGWS were achieved in 30 wrists (90.9%). The average MMWS outcome was 92.6 (range, 75–100).

Conclusion

Our experience with bridge plating was similar to that previously reported in the earlier publications. Compared with the conventional technique, bridge plating through a PQ-sparing approach may help in managing metaphyseal comminuted fractures of both cortices with a reduced radio-ulnar index.

Distal Radius Fractures: AAOS Appropriate Use Criteria Versus Actual Management at a Level I Trauma Center

BACKGROUND

The aim of this study is to determine whether the American Academy of Orthopaedic Surgeons' (AAOS) Appropriate Use Criteria (AUC) for distal radius fractures correlates with actual treatment by orthopedic hand surgeons at a level I trauma center.

METHODS

ICD-9 codes were used to retrospectively identify patients who presented with wrist fractures over 1 year. Patients with isolated distal radius fractures were evaluated using the AAOS AUC application for distal radius fractures. Actual treatment was then compared with treatment recommended by the AUC.

RESULTS

Of the 112 patients, 64 (57%) received treatment that matched the AAOS AUC recommendation as an "appropriate treatment." Actual management matched the AUC recommendation 100%, 7%, and 50% of the time, for Arbeitsgemeinschaft für Osteosynthesefragen/Orthopaedic Trauma Association (AO/OTA) type A, B, and C fractures, respectively. Surgery was performed for type A, B, and C fractures 30%, 7%, and 50% of the time, respectively. For type B fractures, only the 2 cases that were managed operatively were in agreement with the AUC. For type C fractures, increased patient age (57 years and older) was significantly associated with nonoperative treatment decisions. Surgeon decisions for nonoperative treatment were in agreement with the AUC recommendations 40% of the time, whereas surgeon decisions for surgery matched the AUC recommendations 97% of the time.

CONCLUSIONS

We found low agreement between actual treatment decisions and the AUC-recommended "appropriate" treatments, especially for the type B and C fractures that were managed nonoperatively. The AUC favors surgery for all intra-articular fractures, while we emphasized age and fracture displacement in our decision-making process.

CaP cement is equivalent to iliac bone graft in filling of large metaphyseal defects: 2 year prospective randomised study on distal radius osteotomies

The purpose of this prospective randomised study was to compare the clinical and radiological outcomes of injectable CaP bone cement with corticocancellous bone graft used to fill voids after corrective opening wedge osteotomies in the distal radius. 17 women/3 men, median age 56 (51.3; 61.0), underwent an open-wedge osteotomy of a dorsal malunion in the distal radius randomised to filling the defect either with bone graft (10) or CaP bone cement (10). Dorsal titanium locking plates were used and the wrist was plastered for 8 weeks. Follow-ups for 24 months included X-rays, CT scans, VAS on wrist and iliac crest, grip strength, ROM, Quick-DASH and Gartland & Werley scores. No difference was found between the 2 groups as to clinical outcome or radiological results with no loss of reduction. One bone graft patient developed a pseudarthrosis and one CaP patient suffered a plate fracture 6 months post-operatively. CaP bone cement is a good alternative to bone graft as a void filler in open-wedge osteotomies of the distal radius. The procedure is shorter, easier with the post-operative advantage of no donor site pain. Level of Evidence Randomised controlled trial. Level I evidence.

Prevalence of posttraumatic arthritis following distal radius fractures in non-osteoporotic patients and the association with radiological measurements, clinician and patient-reported outcomes

INTRODUCTION

Outcomes of non-osteoporotic patients who sustained a distal radius fracture (DRF) have not gained much attention in recent literature. The aims of this study were to determine the prevalence of posttraumatic arthritis (PA), to analyze associations of radiological measurements, clinician-reported and patient-reported outcomes (CROs and PROs) with PA and gain insight into employment changes after DRF in non-osteoporotic patients.

METHODS

Non-osteoporotic patients following a DRF were selected. Radiographs of both wrists were obtained at follow-up and the degree of PA was determined. Radiological measurements consisted of grading of PA, ulnar variance, radial length, radial inclination, dorsal tilt, distal radio-ulnar joint width, scapholunate dissociation, step-off and gap. Active range of motion and grip strength measurements were performed and all patients filled in four questionnaires to assess pain, upper extremity functioning, and health status (Disability of Arm, Shoulder and Hand; Patient Reported Wrist Evaluation; Michigan Hand Questionnaire; Short Form-36).

RESULTS

Seventy-three patients (32 women, 41 men) with a mean age of 33.5 (SD 9.2) years were included. Prevalence of PA was 32% at a median follow-up of 62.0 months. Patients with PA had statistically significant longer radial length (1.1 mm, 95% CI - 2.1; - 0.0, p = 0.045). Patients with PA had a statistically significant diminished flexion/extension arc of motion (12.0°, p = 0.008) and ulnar/radial deviation arc of motion (6.3°, p = 0.018). When corrected for dominance, all grip strength measurements were not statistically significantly different between patients with and without PA. Statistically significant poorer PROs in patients with PA were the MHQ subscales general functioning (65 versus 75, p = 0.018), esthetics (94 versus 100, p = 0.037), satisfaction (75 versus 92, p = 0.042) and total score of the MHQ (83 versus 91, p = 0.044), as well as the SF-36 subscale physical functioning (95 versus 100, p = 0.028). In regression analyses the DASH, PRWE function and PRWE total were statistically significantly associated with flexion/extension arc of motion. Seven patients (10%) changed or left their occupation because of the DRF.

CONCLUSION

Non-osteoporotic patients had a considerably high prevalence of PA following DRFs, despite a relatively short follow-up time. Patients with longer radial length more often had PA. Irrespective of AO/OTA fracture type, patients with PA had diminished range of motion, but no altered grip strength measurements. Non-osteoporotic patients following DRFs perceived diminished general functioning and dissatisfaction, which was impacted by the diminished active range of motion. Pain or impaired general health status was not reported. The PRO MHQ might be a valuable evaluation tool in this patient group. Change of occupation following DRFs should receive attention in further research.

Preexisting Carpal and Carpometacarpal Osteoarthritis Has No Impact on Function after Distal Radius Fractures

Background  Functional outcomes of distal radius fractures vary widely regardless of treatment methods. Purpose  This study aims to verify whether preexisting carpal and carpometacarpal (CMC) osteoarthritis (OA) will negatively impact wrist functional outcome in patients with distal radius fractures. Patients and Methods  A retrospective case-control study was done using a prospective trauma database. Patients were matched 1:1 in two groups based on the presence of wrist or carpal arthritis (OA). The groups were matched for sex, follow-up, and treatment type. Patients were followed up for a minimum of 1 year and functional outcomes were assessed using validated scores. Results  A total of 61 patients were included. Mean age was 63 years (range: 20-85) and average follow-up was 26 months. There were 31 patients in the OA+ group and 30 in the OA- group. Forty-one patients were treated surgically and 20 nonoperatively. None of the patients in the OA- developed OA during follow-up. Both groups were comparable for sex, residual deformity, and follow-up. There was no significant difference for the visual analog scale, Short Form-12, Quick Disability Arm Shoulder Hand, and Patient-rated Wrist Evaluation, or for radiographic outcomes. Conclusion  Preexisting OA in the wrist or CMC does not seem to impact outcomes of distal radius fractures, regardless of treatment, age, or sex. Although this is a negative study, the results are important to help counsel patients with distal radius fractures. Further work must be done to identify other potential causes for negative outcomes. Level of Evidence  Level III, prognostic study.

Distal Radius Fractures in the Elderly

Distal radius fractures are common in elderly patients, and the incidence continues to increase as the population ages. The goal of treatment is to provide a painless extremity with good function. In surgical decision making, special attention should be given to the patient's bone quality and functional activity level. Most of these fractures can be treated nonsurgically, and careful closed reduction should aim for maintenance of anatomic alignment with a focus on protecting fragile soft tissues. Locked plating is typically used for fracture management when surgical fixation is appropriate. Surgical treatment improves alignment, but improvement in radiographic parameters may not lead to better clinical outcomes. Treatment principles, strategies, and clinical outcomes vary for these injuries, with elderly patients warranting special consideration.

Clinical and radiologic factors affecting functional outcomes after volar locking plate fixation of dorsal angulated distal radius fractures

BACKGROUND

The aim of the present study was to identify the clinical and radiologic factors affecting functional outcomes in patients with a distal radius fractures (DRFs) treated by volar locking plate fixation.

PATIENTS AND METHODS

Prospective cohort of patients with dorsally angulated DRFs requiring the volar locking plate fixation were recruited during one year. We evaluated wrist motion, grip strength, and DASH score at 3, 6 and 12 months after surgery. The factors assessed for their influence on functional outcomes included clinical variables representing patients' characteristics (age, gender, whether the dominant hand was fractured, the fracture mechanism, fracture classification, complications after surgery, and diabetes mellitus) and radiologic variables representing amount of displacement and quality of reduction (volar tilt angle, radial height, radial inclination, and ulnar variance) at initial injury plain radiographs before manual reduction, and at the radiographs within 1 week of surgery. We conducted a simple and multiple linear regression analysis to identify the clinical and radiologic factors affecting functional outcomes.

RESULTS

89 patients were recruited at 1 year after surgery. In the multivariate linear regression analysis, the significant factor affecting DASH score was diabetes (p = 0.025) and the ulnar variance after surgery (p = 0.042) after adjusting for age. However, Age was the only statistically significant factor affected grip strength (p = 0.024) and wrist motion (p = 0.012).

CONCLUSIONS

Because the ulnar variance after surgery is the modifiable factor in contrast with other factors such as diabetes and age, surgeons should pay attention to restore ulnar variance to improve functional outcomes during volar locking plate fixation in patients with distal radius fractures.

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.

Patient-Reported Outcome Measures for Hand and Wrist Trauma: Is There Sufficient Evidence of Reliability, Validity, and Responsiveness?

BACKGROUND

Patient-reported outcome measures (PROMs) are important tools for assessing outcomes following injuries to the hand and wrist. Many commonly used PROMs have no evidence of reliability, validity, and responsiveness in a hand and wrist trauma population. This systematic review examines the PROMs used in the assessment of hand and wrist trauma patients, and the evidence for reliability, validity, and responsiveness of each measure in this population.

METHODS

A systematic review of Pubmed, Medline, and CINAHL searching for randomized controlled trials of patients with traumatic injuries to the hand and wrist was carried out to identify the PROMs. For each identified PROM, evidence of reliability, validity, and responsiveness was identified using a further systematic review of the Pubmed, Medline, CINAHL, and reverse citation trail audit procedure.

RESULTS

The PROM used most often was the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire; the Patient-Rated Wrist Evaluation (PRWE), Gartland and Werley score, Michigan Hand Outcomes score, Mayo Wrist Score, and Short Form 36 were also commonly used. Only the DASH and PRWE have evidence of reliability, validity, and responsiveness in patients with traumatic injuries to the hand and wrist; other measures either have incomplete evidence or evidence gathered in a nontraumatic population.

CONCLUSIONS

The DASH and PRWE both have evidence of reliability, validity, and responsiveness in a hand and wrist trauma population. Other PROMs used to assess hand and wrist trauma patients do not. This should be considered when selecting a PROM for patients with traumatic hand and wrist pathology.

Which Are the Most Relevant Questions in the Assessment of Outcome after Distal Radial Fractures?

A study was designed to determine which wrist scoring system best correlates with patient satisfaction and which individual variables predict a satisfactory outcome. We looked at forty-five females and 5 males with wrist fractures at 12 weeks after injury and compared their level of satisfaction with various respected outcome measures. The mean age was 66 years. Multivariate regression analysis was carried out using a statistical software package. Patient satisfaction correlated best with the MacDermid, Watts, and DASH scores. The variables in these scoring systems that predicted satisfaction were pain and ability to perform household chores or usual occupation, open packets, and cut meat. The four most important questions to ask in the clinic following wrist fractures are about severity of pain and ability to open packets, cut meat, and perform household chores or usual occupation. This may provide simple and more concise means of assessing outcome after distal radial fractures. Level of evidence is level 4.

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.

What factors are associated with a second opioid prescription after treatment of distal radius fractures with a volar locking plate?

PURPOSE

Knowledge of factors associated with patient's requests for a second opioid prescription after volar plate fixation of a fracture of the distal radius might inform better pain management protocols and encourage decreased and safer use of opioids. This study tested the primary null hypothesis that there is no difference in demographics, prior opioid prescriptions, injury characteristics, and psychological factors between patients that do and do not receive a second opioid prescription following treatment volar locking plate after distal radius fracture.

PATIENTS AND METHODS

We used data on 206 patients enrolled in one of two prospective studies. Their mean age was 53 years ± SD 15, and 60 (30 %) were men. Forty-seven (23 %) patients received a second opioid prescription. We recorded additional demographics, AO fracture type, American Society for Anesthesiologists (ASA) classification, radiographic parameters at the time of injury prior to reduction and after surgery, and catastrophic thinking.

RESULTS

Male sex (odds ratio [OR] 2.2, 95 % confidence interval [CI] 1.0-4.6, partial pseudo R (2) = 0.018, P = 0.044) and greater dorsal angulation of the articular surface on the lateral post injury radiograph (OR 0.98, 95 % CI 0.96 to 1.0, partial pseudo R (2) = 0.033, P = 0.040) were associated with a second opioid prescription after surgery (pseudo R (2) 0.12, P = 0.0071).

CONCLUSIONS

One measure of fracture severity (dorsal displacement) was independently associated with a second opioid prescription, but alone it accounted for 3.3 % of the variation. Other factors such as the patient's expectation prior to surgery, in particular the realization that injury and surgery hurt, might be addressed in future research.

Load transfer at the distal ulna following simulated distal radius fracture malalignment

PURPOSE

To measure the effects of distal radius malalignment on loading at the distal ulna.

METHODS

Using an adjustable mechanism to simulate angulated and translated malalignments, clinically relevant distal radius deformities were simulated in a cadaveric model. A custom-built load cell was inserted just proximal to the native ulna head to measure the resultant force and torque in the distal ulna. Loads were measured before and after transecting the triangular fibrocartilage complex (TFCC).

RESULTS

There was an increase in distal ulna load and torque with increasing dorsal translation and angulation. Combined conditions of angulation and translation increased force and torque in the distal ulna to a greater extent than with either condition in isolation. Transecting the TFCC resulted in a reduction in distal ulna load and torque.

CONCLUSIONS

A progressive increase in load at the distal ulna was observed with increasing severity of malalignment, which may be an important contributor to residual ulnar wrist pain and dysfunction. However, no clear-cut threshold of malalignment of a dorsally angulated and translated distal radius fracture was identified. These observations suggest that radius deformities cause articular incongruity, which increases TFCC tension and distal radioulnar joint load. Cutting of the TFCC decreased distal ulna loading, likely by releasing the articular constraining effect of the TFCC on the distal radioulnar joint, allowing the radius to rotate more freely with respect to the ulna.

CLINICAL RELEVANCE

Anatomical reduction of a distal radius fracture minimizes the forces in the distal ulna and may reduce residual ulnar wrist pain and dysfunction.

Effect of anxiety and catastrophic pain ideation on early recovery after surgery for distal radius fractures

PURPOSE

To evaluate the effects of preoperative anxiety and catastrophic pain ideation on perceived disability and objective measures after distal radius fracture surgery.

METHODS

A total of 121 patients with distal radius fractures treated with volar plate fixation were enrolled. The wrist range of motion (ROM), grip strength, and perceived disability as measured by the Michigan Hand Questionnaire (MHQ) score were assessed 4, 12, and 24 weeks after surgery. To evaluate psychological factors related to pain, catastrophic pain ideation was measured using the Pain Catastrophizing Scale (PCS) and pain anxiety was measured using the Pain Anxiety Symptom Scale (PASS). Then relative contributions of pain anxiety and catastrophic pain ideation and other clinical parameters to functional recovery in terms of grip strength, ROM, and MHQ score were assessed.

RESULTS

An increase in the PCS score was associated with the wrist ROM and grip strength only at week 4, whereas an increase in the PASS score was associated with the wrist ROM at week 4 and grip strength at weeks 4 and 12. According to a multivariate regression analysis, an increase in the PCS score was associated with a decrease in grip strength, ROM, and MHQ score at week 4; and an increase in the PASS score was associated with a decrease in grip strength, ROM, and MHQ score at week 4 and grip strength and MHQ score at week 12. At week 24, only age and fracture severity were associated with the MHQ score. In addition, age was associated with grip strength and fracture type was associated with ROM.

CONCLUSIONS

Preoperative PCS and PASS were significantly associated with delayed recovery as evidenced by scores on both objective and subjective measures of function. Given these relationships, it becomes important to assess preoperative PCS and PASS and address issues for patients at risk with brief psychosocial intervention early in the recovery process.

Quality of life after volar locked plating: a 10-year follow-up study of patients with intra-articular distal radius fractures

Background

This study aimed to present functional results and patient’s health related quality of life (HRQOL) data ten years after volar locked plate fixation (VPF) of unstable intra-articular distal radial fractures (DRF).

Methods

Thirty-nine patients with a mean age of sixty-one years were operatively treated with VPF after intra-articular distal radial fractures. They were evaluated two, six, and ten years postoperatively according to the Gartland and Werley score. For subjective evaluation the Short Form 36 (SF-36) and the Disability of Arm, Shoulder and Hand (DASH) questionnaires were adopted.

Results

Overall, wrist function did not differ significantly two, six and ten years after the operation. Over 90% patients achieved “good” or “excellent” results ten years after surgery according to the Gartland and Werley score. Ten years postoperatively the results of the SF 36 did not differ significantly from the two- and six-year follow-up. Overall findings from the SF-36 did not differ significantly from the data of Austrian and American norm populations. Only in the subscale of mental health (MH) the ten-year follow-up did show significantly poorer results (p = 0.045) compared to the Austrian norm population. The median DASH scores did not show significant differences during the ten-year follow-up period.

Conclusion

The ten-year results of this single-center study suggest that operative treatment of intra-articular DRF with volar locked plates is a useful and satisfactory therapy option, both in terms of function and HRQOL.

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.

Radiographic alignment of unstable distal radius fractures fixed with 1 or 2 rows of screws in volar locking plates

PURPOSE

We tested the null hypothesis that there is no difference in the change in volar tilt of the articular surface of the distal radius on lateral radiographs obtained before suture removal and 3 months or more after surgical fracture fixation when 1 or 2 rows of screws are used in the distal part of a volar locked plate.

METHODS

We retrospectively identified 364 consecutive patients with a distal radius fracture treated by 2 surgeons with open reduction and volar locked plate fixation between 2007 and 2011 at our institution. A manually case-matched design with one-to-one matching of 2 different strategies for screws in the distal part of the plate (1 row versus 2 rows) on the basis of sex, AO type, presence of dorsal comminution, ulna fracture, mechanism of injury, and age (± 8 y) resulted in a group of 34 pairs, 68 total fractures. Radiographic alignment was measured before suture removal and 3 months or more after surgery.

RESULTS

The change in volar tilt of the articular surface was -1.2° in the 1-row group and -0.9° in the 2-row group, which was not significantly different. The secondary displacement of radial inclination and ulnar variance were likewise small and not statistically significant.

CONCLUSIONS

We found no advantage of 2 rows of distal screws over a single row of screws with respect to maintenance of achieved restoration of volar angulation after volar locked plate fixation of AO type A and C fractures of the distal radius.

Outcomes of pin and plaster versus locking plate in distal radius intraarticular fractures

Background

Distal radius fractures are among the most prevalent fractures predictive of probable occurrence of other osteoporotic fractures. They are treated via a variety of methods, but the best treatment has not been defined yet.

Objectives

This study was performed to compare the results of open reduction and internal fixation with locking plates versus the pin and plaster method.

Materials and Methods

In this prospective study, 114 patients aged 40 to 60 years with Fernandez type III fracture referring to Imam-Reza and Mehr hospitals of Mashhad from 2009 to 2011, were selected randomly; after obtaining informed consent, they were treated with pin and plaster fixation (n = 57) or internal fixation with the volar locking plate (n = 57). They were compared at the one year follow up. Demographic features and standard radiographic indices were recorded and MAYO, DASH and SF - 36 tests were performed. Data was analyzed by SPSS software version 13, with descriptive indices, Mann-Whitney and Chi-square tests.

Results

SF-36 test demonstrated a better general health (P < 0.001), mental health (P = 0.006), physical functioning (P < 0.001), social functioning (P < 0.001) and energy/fatigue (P < 0.001) in LCP group. However, pain (P = 0.647) was not significantly different between the groups. Physical limitation (P < 0.001) and emotional limitation (P < 0.001) were greater in the pin and plaster group. Also, in the LCP group mean MAYO score (P < 0.001) was more than pin and plaster group. Mean DASH score was not different between the groups (P = 0.218). The rate of acceptable results of radiographic indices (P < 0.001), grip strength (P < 0.001) and range of motion in supination-pronation (P < 0.001) in LCP method were better than the pin and plaster method.

Conclusions

In treatment of intra-articular distal radius fractures in middle-aged patients internal fixation with locking plates may be prefered to pin and plaster as the treatment of choice.

Persistent ulnar-sided wrist pain after treatment of triquetral dorsal chip fracture: six cases related to triangular fibrocartilage complex injury

INTRODUCTION

Persistent ulnar-sided wrist pain after treatment of triquetral dorsal chip fracture even after union is a matter of concern. There could be various reasons for this persistent pain like arthritis, instability, fractures and non-union. We correlate our findings of physical examination and wrist arthroscopy as triangular fibrocartilage complex injury to be one of the causes of this persistent pain.

PATIENTS

Six subjects who had persistent ulnocarpal joint pain and tenderness after triquetral dorsal chip fracture, despite 2 months of conservative treatment, were subjected to physical tests. If the physical examination yields positive results, then magnetic resonance imaging followed by arthroscopic treatment was performed. The six patients were then evaluated using the visual analogue scale, the Mayo modified wrist score, and the grip strength test.

RESULTS

Triangular fibrocartilage complex (TFCC) injury was observed in all six cases and partial TFCC resection and synovectomy were performed. Analysis of the visual analogue scale, Mayo modified wrist score, and grip strength test data revealed statistically significant improvements (P < 0.05).

CONCLUSION

In addition to several causes reported in the published literature, TFCC injury can be a cause of persistent ulnar pain after treatment of triquetral dorsal chip fracture. Arthroscopic partial TFCC resection can be considered to be a suitable treatment for such cases.

Management of distal radius fractures from the North American perspective

In North America, the rate of nonoperative management of displaced distal radius fractures has declined as the rate of internal fixation has increased. Volar locking plate fixation has increased in popularity despite a lack of supportive level 1 evidence. Issues of cost-effectiveness are relevant because there is no best-practice treatment at this stage. Clinicians should be aware of the goals of treatment and challenges, particularly in managing elderly patients with distal radius fractures. Large, randomized controlled trials or meta-analyses may provide answers about when operative intervention is favored over nonoperative management and which operative intervention provides the best outcomes.

Recovery after fracture of the distal radius

Stretching exercises are an important part of recovery after sustaining a fracture of the distal radius. However, from the patient's perspective, painful stretching exercises can be counterintuitive after injury. Stretching exercises are straightforward and do not require a significant amount of coaching. It is ultimately the protectiveness, passivity, and sometimes a sense of futility that require coaching. The key for the provider is to empathize with the difficult and counterintuitive nature of the recovery process.

Mid-term functional outcome after the internal fixation of distal radius fractures

Background

Distal radius fracture is a common injury with a variety of operative and non-operative management options. There remains debate as to the optimal treatment for a given patient and fracture. Despite the popularity of volar locking plate fixation, there are few large cohort or long term follow up studies to justify this modality. Our aim was to report the functional outcome of a large number of patients at a significant follow up time after fixation of their distal radius with a volar locking plate.

Methods

180 patients with 183 fractures and a mean age of 62.4 years were followed up retrospectively at a mean of 30 months (Standard deviation = 10.4). Functional assessment was performed using the Disabilities of the Arm, Shoulder and Hand (DASH) and modified MAYO wrist scores. Statistical analysis was performed to identify possible variables affecting outcome and radiographs were assessed to determine time to fracture union.

Results

The median DASH score was 2.3 and median MAYO score was 90 for the whole group. Overall, 133 patients (74%) had a good or excellent DASH and MAYO score. Statistical analysis showed that no specific variable including gender, age, fracture type, post-operative immobilisation or surgeon grade significantly affected outcome. Complications occurred in 27 patients (15%) and in 11 patients were major (6%).

Conclusion

This single centre large population series demonstrates good to excellent results in the majority of patients after volar locking plate fixation of the distal radius, with complication rates comparable to other non-operative and operative treatment modalities. On this basis we recommend this mode of fixation for distal radius fractures requiting operative intervention.

Reliability and validity of the Danish version of the disabilities of arm, shoulder, and hand questionnaire in patients with fractured wrists

The disabilities of arm, shoulder, and hand (DASH) questionnaire is a 30-item region-specific questionnaire that is used to measure the effect of treatment of the upper extremity. The purpose of this study was to assess the reliability of, and validate, the Danish version of the DASH score in patients with fractured wrists. Sixty patients were studied. We investigated internal consistency and test-retest reliability, convergent validity, content validity and responsiveness. Time to complete questionnaire was 11 minutes and two questionnaires were not usable. The internal consistency was sufficient (Cronbach's alpha 0.96 and intraclass correlation coefficient 0.89). The difference in the mean was 4.6 (CI: 0.48 to 8.72, p = 0.03). Convergent validity at first and last control was high for both pain, 0.46 and 0.40 respectively, and for physical mobility, 0.64 and 0.65 respectively, indicating that results confirmed other similar scores. We conclude that the Danish version of the 30-item DASH questionnaire is valid and practical for patients with fractured wrists.
