Does endoscopic carpal tunnel release during distal radial fracture fixation improve outcomes? A randomized controlled trial.

This study investigated the functional outcome of prophylactic carpal tunnel release during distal radial fracture fixation. A total of 60 patients undergoing anterior locking plate fixation for a distal radial fracture were randomized into two groups: one having prophylactic endoscopic carpal tunnel release and the other serving as a control. Functional outcomes were assessed using the Patient-Reported Wrist Evaluation, Quick Disabilities of the Arm, Shoulder, and Hand, EuroQol 5-Dimension 5-Level questionnaire, Boston Carpal Tunnel Questionnaire, Pain Numerical Rating Scale, grip strength and finger-to-palm distance over a 12-month period. The study found no significant differences in overall functional outcomes or complications between the groups.Level of evidence: I.

Partial Denervation of the Thumb Carpometacarpal Joint: A New Technique.

To report the clinical outcomes of partial denervation for the treatment of basilar thumb joint arthritis. Patients who underwent partial denervation of the basilar thumb joint for osteoarthritis from a single center between 2019 and 2021 were recruited into the study. This involved a technique that involved cauterization of the joint capsule and its innervation through the branches of the superficial radial, palmar cutaneous branch of the median, lateral antebrachial, and ulnar nerves. Patients were followed up postoperatively to record clinical (grip strength, thumb apposition and opposition pinch grip strength, Kapandji score) and patient-reported outcomes (visual analogue scale [VAS], Quick Disabilities of the Arm, Shoulder and Hand [QuickDASH], Patient-reported Wrist Evaluation [PRWE]). Twelve patients (15 carpometacarpal joints; 9 female and 3 male patients) underwent a partial denervation of the thumb (Eaton stage 3-4). The mean age at the time of surgery was 63 ± 5 years (range 56-72). The mean clinical follow-up duration was 23 ± 11 months (range 9-42 months), and functional score follow-up duration was 27 ± 7 months (range 14-42 months). At the latest clinical follow, VAS score, Kapandji score, grip strength, and thumb apposition/opposition pinch strength all improved significantly (P < .05). The mean QuickDASH score was 30 ± 16, and PRWE score was 32 ± 17. Patients who had unilateral partial thumb denervation demonstrated greater improvement in grip strength than patients who had bilateral partial thumb denervation procedures (P = .01). In this clinical case series, our method of basilar thumb joint partial denervation has been effective in improving clinical outcomes and reducing pain due to osteoarthritis. IV, case series.

Occupational Performance 1 Year After a Distal Radius Fracture From the Perspective of the International Classification of Functioning, Disability and Health.

Distal radius fractures (DRFs) frequently compromise independent functioning. To analyze occupational performance post-DRF using the Canadian Occupational Performance Measure (COPM) and related interviews, guided by the International Classification of Functioning, Disability and Health (ICF). COPM score was compared with standard metrics: Patient-Reported Wrist Evaluation (PRWE) and Participation Behavior Questionnaire (PBQ). Through a semistructured COPM interview, participants highlighted self-care, productivity, and leisure. They completed the PRWE and PBQ, linking results to ICF sets. Prospective cohort. Outpatient hand surgery clinic at a trauma center. Patients (N = 120), 1 yr post-DRF. Incorporated COPM, PRWE, and PBQ, linked to ICF. Analysis identified 73 codes, aligning with 30 ICF Hand Conditions codes. Main concerns related to self-care (15.21%), leisure (12.16%), and productivity (16.22%). Major challenges pertained to domestic (67.00%) and civic life (64.53%) within ICF. Occupational performance was positively correlated with participation (r = .62) and inversely with disability (r = -.62). DRFs result in varied occupational challenges that are not always reflected in standard measures. The COPM offers a comprehensive insight into post-DRF patient challenges, emphasizing the value of diverse clinical assessment approaches. What This Article Adds: This study highlights the importance of a holistic approach in occupational therapy for DRF patients, revealing that standard measurements might overlook key challenges that they face. By adopting broader evaluative methods, occupational therapists can better address patient-specific needs and enhance their rehabilitation outcomes.

The Minimum Clinically Important Difference for the Patient-Rated Wrist Evaluation in Surgical Fixation of Distal Radius Fractures: Does Hand Dominance Make a Difference?

BackgroundDistal radius fractures (DRFs) are common orthopaedic injuries. They can be treated in many ways, but the volar locking plate (VLP) is more frequent. Currently, there is limited information regarding the minimum clinically important difference (MCID) in surgically treated DRFs. The purpose of this study was to calculate MCID values for the Patient-Reported Wrist Evaluation (PRWE) in the setting of VLP-treated DRFs. MethodsA retrospective review was conducted for patients with isolated, surgically-treated DRFs with a VLP. Exclusions included any concomitant procedure other than a carpal tunnel release, skeletal immaturity, polytrauma, open fracture, or missing PRWE data. MCID was calculated using PRWE, an overall health question, and the anchor-based method. ResultsA total of 131 patients were identified. Approximately 54.2% injured their dominant hand. AO/OTA classification 23C was the most common (n=89, 67.9%). Average baseline, 6-week, and 12-week PRWE were 71.8 ± 19.6, 34.3 ± 20.1, and 21.2 ± 18.0 respectively. This corresponds to an average change from baseline PRWE at 6 weeks and 12 weeks of -37.5 ± 23.4 and -50.6 ± 22.3, respectively.Average MCID values for 6 weeks and 12 weeks were 43.1 ± 18 and 56.0 ± 20.0, respectively (p<0.001). Hand dominance did not correlate with MCID value (rs = 0.084 at six weeks, rs = 0.099 at 12 weeks). MCID value additionally did not correlate with sex, AO/OTA classification, smoking status, ASA score, or BMI. Treatment at a level 1 trauma center and diagnosis of anxiety and/or depression correlated with a higher 6-week MCID value (rs = 0.308 and rs = 0.410, respectively). Increasing age weakly correlated with higher 12-week MCID value (rs = 0.352). ConclusionsThis study demonstrated an MCID calculation using an overall health anchor. MCID value varied with follow-up time and correlated weakly with age, diagnosis of anxiety and/or depression, and treatment facility, but it did not correlate with injury of the dominant hand. Future research should analyze how to apply MCID and identify successful treatment in the setting of DRF care.

A comparison of the functional results and costs of functional cast and volar-flexion ulnar deviation cast at 2-year follow-up in 105 patients aged 65 and older with dorsally displaced distal radius fracture: A randomized controlled trial.

Non-operative treatment is the most common treatment option for older patients with distal radius fracture (DRF). Traditionally, wrists have been placed in volar-flexion and ulnar deviation position (VFUDC). In recent years, there has been a trend towards using a functional position cast (FC). However, long-term results for these different casting positions are lacking. This randomized, controlled, prospective study evaluates the functional results and costs of the 2 casting positions in patients 65 and older with DRF. Primary end point in this study was Patient-Reported Wrist Evaluation (PRWE) at 24 months, and secondary end points were cost-effectiveness of treatment, health-related quality of life measurement (15D), short version of Disabilities of arm, shoulder and hand score (QuickDASH), and VAS at 24 months. The trial was registered in ClinicalTrials.gov (NCT02894983, https://clinicaltrials.gov/ct2/show/NCT02894983). We enrolled 105 patients, of which 81 (77%) continued until 24-month follow-up. 8 patients (18%) were operated in the VFUDC group and 4 (11%) in the FC group. Patients in the VFUDC group also received more frequent physical therapy. The difference in PRWE score between the VFUDC and FC groups at 24 months was -4.31. The difference in the cost of treatment per patient was €590. Both findings favored FC. We found a slight, but consistent difference in the functional results between groups. These results suggest that VFUDC is not superior to FC when treating Colles' type DRF. Cost analysis revealed overall costs in the VFUDC group are nearly double those in the FC group, mostly due to more physical therapy, additional visits to hospital, and additional examinations. Therefore, we recommend FC in older patients with Colles' type DRF.

Application of Current Knowledge of Blood Flow Restriction Training for Use on Upper Extremity Injuries

Blood flow restriction (BFR) utilizes a cuff or tourniquet to induce muscle hypoxia by maintaining arterial flow, while restricting venous return. This technique has recently gained popularity in healthy patients and patients undergoing rehabilitation. Two studies have shown that patients who use BFR, in addition to the standard therapy protocol, following an upper extremity injury (UEI) have reduced pain and improved Patient-Reported Wrist Evaluation scores. The use of BFR in the upper extremity of healthy patients and patients with a prior lower extremity injury have shown statistically significant improvements in muscle strength and muscle hypertrophy. Further studies focusing on BFR training following various upper extremity injuries are needed to determine the potential impact on clinical outcomes. The purpose of this review was to analyze the use of BFR following lower extremity injuries, summarize the literature of BFR for upper extremity injuries, and consider the application of BFR following upper extremity injuries in the future.

Dorsal bridging plates for the treatment of high and low energy distal radius fractures

Distal radius fractures are common and treatment of complex fracture pattens can be challenging. We assessed functional outcomes, radiographic analysis, and complications of 26 distal radius fractures treated with dorsal bridging plate (DBP) at a mean of 14 months post plate removal (6–34 months). Radiographic parameters were measured pre- and post-operatively and patient reported wrist evaluation scores, patient reported wrist range of movement and satisfaction scores. Mean post-operative total PRWE was 26 (range 0–76) and mean wrist mobility 52° flexion (range 10°–85°) and 50° extension (range 10°–85°). Mean post-operative patient satisfaction score was 89% (range 50–100%). Four patients developed complications (one EPL rupture and three developed CRPS). DBP can reliably restore distal radius anatomy and is associated with good functional outcome scores, return of functional range of wrist movement and high levels of patient satisfaction.

Clinical Results of Distal Radius Intraarticular Comminuted Fractures in the Elderly: A Retrospective Comparative Analysis of Different Fixation Methods.

IntroductionDistal radius intraarticular fractures in the elderly population are likely to cause impaired clinical outcomes. Intraarticular fracture treatment in the literature is a debatable issue with mixed results. Here, we aimed to present a tertiary trauma center experience with plate fixation and K wire-assisted external fixator in elderlies over 60 years old.Material and methodsPatients who were diagnosed with an unstable intraarticular distal radius fracture and received surgical treatment with plate fixation or K wire-assisted external fixator between 2016 January and 2020 January were included in the study. Patients were evaluated retrospectively in terms of radiologic stability criteria and clinical outcomes.ResultsThere were 27 patients; 14 in the volar plate group (group 1) and 13 (group 2) in the external fixator group. The mean age was 64.2 (60-72) in group 1 and 67.7 (60-76) in group 2. The mean follow-up time was 31.6 (12-63) in group 1 and 28.8 (12-59) in group 2. The mean quick disabilities of the arm, shoulder, and hand (Q-DASH) score was 25.7 (5-75) in group 1 and 24.4 (10-87) in group 2. The mean patient-reported wrist evaluation (PRWE) was 27.1 (6-87) in group 1 and 31.4 (10-87) in group 2. There was no statistical difference between groups in terms of clinical scores, hospital stay, follow-up, and complications. (p>0.05).ConclusionAlthough open reduction and plate fixation and K wire-assisted external fixator are viable options for providing radiologic union, unsatisfactory clinical outcomes were maintained independently of the fixation method in elderly patients.

Comparison of immobilization periods following open reduction and internal fixation of distal radius fracture: A systematic review and meta-analysis

Study DesignSystematic review and meta-analysis. IntroductionThe use of volar locking plate (VLP) in the fixation of fracture fragments promised a new era in the management of distal radius fracture (DRF). Purpose of the StudyTo compare the patient-reported outcomes, functional outcomes, pain, and adverse events between the different periods of immobilization following open reduction and internal fixation of DRFs with VLP. MethodsWe searched Medline/Pubmed, Web of Science, Ovid, and CINAHL. The inclusion criteria was randomized controlled trials that compared different immobilization periods after open reduction and internal fixation of DRFs with VLP. The last search was performed on 2 June 2020. The different immobilization periods were divided into the following 3 groups: ≤1-week group, 2-3-week group, and 5-6-week group. ResultsSeven eligible randomized controlled trials provided data on 509 patients. We found that compared to 5-6-week group, ≤1-week and 2-3-week groups showed a reduction in overall Patient-Reported Wrist Evaluation score (SMD = –0.48, 95% CI –0.73 to –0.22, P < .001; SMD = –0.69, 95% CI –0.97 to –0.41, P < .001, respectively). We also found that there were improvements in the other patient-reported outcomes including overall Disabilities of the Arm, Shoulder, and Hand score and pain; and functional outcomes including overall grip strength and range of motion measures in favor of ≤1-week and 2-3-week groups. ConclusionThis systematic review and meta-analysis showed that compared to immobilization for 5 to 6 weeks after DRF repair, immobilization for ≤1 week or 2-3 weeks showed improvements in the patients-reported outcomes and functional outcomes. The differences between the 3 immobilization groups may not be clinically important considering the small changes as follow up progresses.

Effect of pre-treatment expectations on post-treatment expectation fulfillment or outcomes in patients with distal radius fracture

BackgroundThe influence of patient expectations on patient-rated outcomes (PRO) after elective orthopedic procedures has been addressed in previous studies. However, the influence of pre-treatment expectations on post-treatment PRO was rarely examined in patients with extremity fractures. PurposeThe purpose of this study was to determine if pre-treatment expectations have an effect on post-treatment expectation fulfillment or PRO in patients surgically and conservatively managed for distal radius fractures (DRFs). Study designProspective cohort study MethodsFor this study, 114 consecutive patients treated for DRF between January 2017 and February 2018 were enrolled. Of the 114 patients, 81 underwent surgical treatment (surgical group), and 33 were managed conservatively (conservative group). All patients completed a 7-item pre-treatment expectation questionnaire initially. There were 66 patients in the surgical group and 25 patients in the conservative group available at the 1-year follow-up and completed a 6-item post-treatment expectation fulfillment questionnaire and patient-reported wrist evaluation (PRWE) questionnaire. ResultsThe surgical group showed a significantly higher median pre-treatment expectation score than the conservative group. However, no significant differences in post-treatment expectation fulfillment scores and PRWE scores were observed between groups. Higher pre-treatment expectation score was moderately correlated with higher post-treatment expectation fulfillment score (r = 0.36, P = 0.003) and lower PRWE score (r = -0.3, P = 0.02) in the surgical group. However, the pre-treatment expectation score was not significantly correlated with the post-treatment expectation fulfillment score (r = -0.09, P = 0.65) or PRWE score (r = -0.02, P = 0.93) in conservative group. In the surgical group, multivariable linear regression analysis showed that post-treatment expectation fulfilment score could be explained by the pre-treatment expectation score (Beta = 0.41, P = 0.001), accounting for 15% of the variance, and PRWE score was also explained by the pre-treatment expectation score (Beta = 0.39, P = 0.001), accounting for 14% of the variance. ConclusionsIn conclusion, higher pre-treatment expectation score was moderately correlated with higher the post-treatment expectation fulfillment score and lower PRWE score, and the pre-treatment expectation score could only explain a small amount of variance seen in the post-treatment expectation fulfillment and PRWE scores in the surgical group. However, there was no association between the pre-treatment expectation score and the post-treatment expectation fulfillment score or the PRWE score in the conservative group.

Arthroscopic dorsal capsulodesis for isolated lunotriquetral interosseous ligament injuries.

We assessed the outcomes of isolated lunotriquetral ligament injuries in ten patients who underwent arthroscopic dorsal capsulodesis. Data from patient records, radiologic images and arthroscopic video records were evaluated. The patients were evaluated for ulnar-sided wrist pain with history and physical examination. Preoperative radiographs and MRIs for pain aetiology were assessed. The patients underwent arthroscopic dorsal capsulodesis and were evaluated 29months (range 19-45) after surgery. Nine patients returned to their original jobs. In one patient pain was aggravated with heavy activities. Mean scapholunate angle was 44°. There were significant improvements postoperatively in pinch and grip strength and MAYO wrist, patient-reported wrist evaluation and pain scores. The wrist flexion-extension and the radial ulnar deviation were significantly improved compared with the contralateral hand. We conclude that arthroscopic dorsal capsulodesis offers effective management for isolated lunotriquetral interosseous ligament injuries.Level of evidence: IV.

Early mobilization vs delayed mobilisation following the use of a volar locking plate with non-vascularized bone graft in scaphoid non-union. A multicentred randomised controlled-trial

PurposeThis randomized clinical trial investigated the potential for early mobilization of the wrist following open reduction and internal fixation (ORIF) with a scaphoid specific volar locking plate and non-vascularized bone graft for scaphoid non-union. Methods16 patients with scaphoid non-union underwent internal fixation with a scaphoid-specific volar locking plate and iliac crest bone graft and were randomized to one of two treatment arms (A) The control were immobilized in a below elbow cast for 6 weeks (n = 9) and (B) The experimental arm were mobilized early with a removable wrist splint (n = 7). Outcomes were measured preoperatively, and at 3 months post operatively. These included the primary outcome of union, and secondary outcomes of grip strength and patient reported outcomes of disabilities of arm shoulder and hand (DASH) and patient reported wrist evaluation (PRWE). Discrete variables were analyzed using the chi squared test while continuous variables used the students t-test. ResultsThe experimental (early mobilization) group developed metalware complications resulting in the early termination of the study. No significant difference in the demographic characteristics of age, gender, time to surgery, smoking status and handedness was found between groups. A significant difference was found in BMI, with significantly higher proportion of obese patients (p = 0.05) in the experimental group. There was no significant difference in the primary outcome measure of the rate of union between groups. The secondary outcomes of grip strength, Dash and PRWE also showed no significant difference between the immobilized and mobilized groups. ConclusionWe recommend immobilization following scaphoid non-union ORIF using a volar locking plate due to high complication rates in our cohort with early mobilization.Type of study/level of evidence: Therapeutic 2.Trial registration.Australian New Zealand Clinical Trials Registry (ACTRN12614001050640).

The evolution of radiological measurements and the association with clinician and patient reported outcome following distal radius fractures in non-osteoporotic patients: what is clinically relevant?

Introduction Following distal radius fractures in young non-osteoporotic patients, clinical relevancy of outcome has been scarcely reported. Outcome can be put in perspective by using measurement errors of radiological measurements and Minimal Important Change when reporting on clinician and patient reported outcome. Aim of this study was to assess the clinical relevance of radiological measurements, clinician and patient reported outcomes following distal radius fractures in young non-osteoporotic patients. Methods Retrospective cohort study. Non-osteoporotic patients following a distal radius fracture were selected. Radiographs of both wrists were obtained at baseline, 6 weeks and at follow-up. Active range of motion and grip strength measurements were obtained at the follow-up visit and 4 questionnaires were answered to assess pain, upper extremity functioning, and health status. Results Seventy-three patients (32 women, 41 men) with a mean age of 33.5 (SD 9.2) years at the time of injury were included. Median follow up was 62 months (IQR 53.0–84.5). Several radiological measurements evolved statistically significantly over time, however none exceeded measurement errors. Flexion/extension difference of injured compared to uninjured wrist (mean difference 11.2°, t = −7.5, df = 72, p < 0.001), exceeded Minimal Important Change, while grip strength differences did not. When comparing patients with DRFs to healthy controls, only the differences on Patient Reported Wrist Evaluation subscales “pain”, “function” and total scores exceeded minimal important change (8, 10 and 13 points, respectively). Multivariable regression analysis revealed statistically significant relationships between residual step-off and respectively diminished flexion/extension (B = −36.8, 95% CI −62; −11.1, p = 0.006), diminished radial/ulnar deviation (B = −17.9, 95% CI −32.0; −3.9, p = 0.013) and worse ShortForm-36 “mental component score” (B = −15.4, 95% CI −26.6; −4.2, p < 0.001). Conclusion Radiological measurements following distal radius fractures seem to evolve over time, but differences were small and were probably not clinically relevant. Range of motion, in particular flexion/extension, was impaired to such extend that it was noticeable for a patient, whereas grip strength was not impaired. The Patient Reported Wrist Evaluation was clinically relevantly diminished. Residual articular incongruency seems to influence range of motion. Implications for rehabilitation Reporting Minimal Important Change regarding clinician and patient reported outcome following distal radius fractures is of more clinical value than reporting on statistical significance. Following distal radius fractures, the changes in radiological measurements do not seem to reflect a clinical relevant change. Range of motion, in particular flexion/extension, should be measured following distal radius fractures, as this might be impaired in a clinically relevant way. Measuring grip strength is of less importance following distal radius fractures, because grip strength does not seem to be affected. Residual articular incongruency seems to influence range of motion and therefore should be reduced to a minimum when treating non-osteoporotic patients.

Validity and Responsiveness of Forearm Strength Measurements in the Evaluation of Distal Radioulnar Joint Implant Arthroplasty

To assess the responsiveness of forearm strength tests and to correlate the change to grip strength and a patient-reported outcome measure used for evaluation of distal radioulnar joint (DRUJ) implant arthroplasty. We performed a retrospective review of 18 patients treated with Herbert (n= 12) and Scheker (n= 6) DRUJ implants. Patients who had undergone the various measurements of arm and grip strength both before surgery and after a minimum follow-up of 1 year were included. Our primary aim was to compare the responsiveness of grip strength with our new methods for measuring forearm torque and lifting strength. The secondary aim was to correlate observed changes in strength measurements to change in a patient-reported outcome measure with use of the patient-reported wrist evaluation (PRWE). Measurements of grip strength, forearm torque, and lifting strength were performed with the Jamar dynamometer and the Kern and Baseline instruments. Preoperative values were compared with 1-year values. Standardized response mean and effect size values were higher for forearm torque than for grip strength. Change in forearm torque and lifting strength had a moderate to strong correlation with change in PRWE. The correlation between grip strength and PRWE was weak. Forearm torque measurements were better than grip strength in detecting changes after DRUJ arthroplasty. It also had a stronger correlation to patient-reported outcome, measured with the PRWE. Forearm torque testing may add further information to the evaluation of DRUJ disorders and their treatments. These tests can provide quantifiable data on the patient's ability to perform various tasks requiring physical strength.

Structural validity and construct validity of the Dutch-Flemish PROMIS® physical function-upper extremity version 2.0 item bank in Dutch patients with upper extremity injuries

Introduction Aim of this study was to validate the Dutch–Flemish Patient-Reported Outcomes Measurement Information System Physical Function – Upper Extremity version 2.0 item bank in patients with upper extremity injuries. Materials and methods Cross-sectional study. Structural validity was assessed using Confirmatory Factor Analysis examining unidimensionality. In addition, a bi-factor model was fitted. Internal consistency was assessed by Cronbach’s alpha. Construct validity was examined by assessing correlations with legacy instruments Disability of Arm Shoulder and Hand, Patient Reported Wrist Evaluation and Michigan Hand Questionnaire subscale Activities in Daily Life. Results A total of 303 patients (144 female) with mean age of 50 years (standard deviation 18) were included. Confirmatory Factor Analysis showed Comparative Fit Index of 0.94, a Tucker Lewis Index of 0.93, a Root Mean Square Error of Approximation of 0.12 and a Standardized Root Mean Residual of 0.09. Factor loadings were all above 0.70. Bifactor analysis showed an omega-H of 0.79 and Explained Common Variance of 0.67. The correlations with the legacy instruments were as expected or higher than expected. Conclusion The Dutch-Flemish Patient-Reported Outcomes Measurement Information System Physical Function – Upper Extremity version 2.0 item bank measures a unidimensional trait and sufficient construct validity was found. IMPLICATIONS FOR REHABILITATION Completing Patient Reported Outcomes is time-consuming for patients and interpretability of outcomes is sometimes unclear due to some variation in psychometric properties. Computerized Adaptive Testing reduces the burden for patients by using an algorithm which decreases the amount of questions that need to be answered to 4 to 7 items. The Dutch-Flemish Patient-Reported Outcomes Measurement Information System Physical Function – Upper Extremity version 2.0 item bank measures a unidimensional trait and has sufficient structural validity, internal consistency and construct validity. After calibration of the Patient-Reported Outcomes Measurement Information System Physical Function – Upper Extremity version 2.0, the item bank is operable to use with Computerized Adaptive Testing.

Minimally invasive internal fixation for extra-articular distal radius fracture: Comparison between volar plate and intramedullary nail

IntroductionThere are numerous internal fixation techniques for distal radius fracture, using pins, plates or nails. Some authors have developed minimally invasive procedures. The aim of the present study was to compare two minimally invasive internal fixation techniques for unstable extra-articular distal radius fracture in women over 50 years of age: volar plate (minimally invasive plate osteosynthesis: MIPO), and intramedullary nail. HypothesesThe main study hypothesis was that the incision scar left by minimally invasive internal fixation is smaller using MIPO than an intramedullary nail. The secondary hypotheses were that the two techniques do not differ in terms of pain, functional score, strength, range of motion and radiologic indices. Material and methodThe series comprised nineteen A2.2 and one A2.1 fractures in 20 female patients with a mean age of 72 years. The first 10 (group 1) received minimally invasive internal fixation of the distal radius by MIPO, and the other 10 (group 2) by intramedullary nail locked onto the distal radius epiphysis and diaphysis. ResultsThe main study hypothesis was confirmed: the incision scar left by minimally invasive internal fixation was smaller using MIPO than an intramedullary nail (mean, 14.3mm vs. 32.8mm). Some of the secondary hypotheses were also confirmed: there were no differences between the two techniques in terms of pain at 6 months, QuickDASH, PRWE (Patient-Reported Wrist Evaluation), range of motion or ulnar variance; two were not confirmed: pain at 6 weeks was less with intramedullary nails, and palmar slope was better with MIPO. Discussion and conclusionThe main study hypothesis was confirmed: the incision scar left by minimally invasive internal fixation was smaller using MIPO than an intramedullary nail. In conclusion, the present findings showed that internal fixation of unstable extra-articular fracture in over 50-year-olds gave better clinical results at 6 weeks using an intramedullary nail, while MIPO required smaller incision. Level of evidenceIII, retrospective study.

Pain, impaired functioning, poor satisfaction and diminished health status eight years following perilunate (fracture) dislocations

Purpose: Perilunate (fracture) dislocations are rare injuries and diminished functional outcomes are reported. However, Patient Reported Outcomes (PROs) following these injuries are rarely described. The aim of this study was to investigate the long-term impact of perilunate (fracture) dislocations using a range of measures, including pain, function, and quality of life.Materials and Methods: This cross-sectional study was conducted from January 2016 until March 2016. Eleven patients who had suffered from perilunate (fracture) dislocations between August 1996 and January 2014 were matched on age and gender with 22 healthy controls. Functional outcome included range of motion and grip strength measurements. The Patient Reported Outcomes included: Patient Reported Wrist Evaluation, Disability of Arm, Shoulder and Hand questionnaire, Michigan Hand Questionnaire and the Short Form-36.Results: The 11 patients that were included (9 males) had a median age at injury of 38 years (IQR 33; 54) and median follow up of 97 months (IQR 84-193). Flexion/extension (mean difference −60°, 95% CI −76, −43, p < 0.001) and ulnar/radial deviation (mean difference −28°, 95% CI −38, −18, p < 0.001) were significantly diminished in patients following perilunate (fracture) dislocations. Grip strength was not affected. The patients experienced significantly more pain as assessed on all pain subscales. Physical functioning was significantly worse in the group with perilunate (fracture) dislocations as assessed on all function subscales, except the PRWE function score and the subscale physical functioning of the Short Form-36. Satisfaction as measured with the Michigan Hand Questionnaire satisfaction subscale (mean difference −36, 95% CI −57, −16, p = 0.002) was also reported poorer. No difference was found regarding work participation.Conclusions: A perilunate (fracture) dislocation has a significant impact on everyday life, as patients experience diminished range of motion, pain, diminished physical functioning, diminished satisfaction and report lower general health status than healthy controls. However, no consequences for work participation were found in this study. Level of evidence 3.Implications for rehabilitationFlexion/extension and ulnar/radial deviation remains limited following perilunate (fracture) dislocations.Grip strength is not diminished in patients with perilunate (fracture) dislocations.Pain, restrictions in physical functioning, diminished satisfaction and lower general health status are likely to be present following perilunate (fracture) dislocations.If conservative treatment including pain medication and rehabilitation strategies do not relief pain following perilunate (fracture) dislocations, surgical treatment options such as wrist denervation or arthrodesis should be considered.

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

IntroductionOutcomes 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.MethodsNon-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).ResultsSeventy-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.ConclusionNon-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.

Long-Term Outcomes After Distal Scaphoid Fractures: A 10-Year Follow-Up

The aim of this study was to evaluate the functional, clinical, and radiological outcome 10 years after distal scaphoid fractures. From a prospective epidemiological study on posttraumatic radial-sided wrist pain, we evaluated 41 cases of distal scaphoid fractures. All cases had been treated nonsurgically in a thumb spica cast. Patients were examined using radiographs, magnetic resonance imaging andcomputed tomography at the time of injury and with computed tomography after a median of 10 years (range, 8-11 years). Fractures were classified according to a modified Prosser classification system. The primary outcome was assessment of self-reported function using Disabilities of the Arm, Shoulder, and Hand (DASH) and Patient-Reported Wrist Evaluation (PRWE). Secondary outcomes were clinical status (range of motion and grip and pinch strength) and to evaluate fracture healing and arthritis in the scaphotrapezium-trapezoid (STT)joint. Functional impairment and pain scores at follow-up were low: median DASH score 2, median PRWE 0, and median visual analog scale (VAS) pain score 0. We found no impairment in range of motion or strength. We found 26 type I fractures, 12 type IIA, 1 type IIC, and 2 type IV. There was 1 asymptomatic nonunion in a type I fracture. Computed tomography revealed arthritis in the STT joint in 7 out of 41 wrists, none of which caused clinical symptoms. From an 8- to 11-year perspective, patients with distal scaphoid fractures report normal self-assessed hand function as well as good wrist motion and strength. The risk for development of posttraumatic STT arthritis was low. Prognostic II.

Stainless steel versus titanium volar multi-axial locking plates for fixation of distal radius fractures: a randomised clinical trial

BackgroundDistal radius fractures are among the most common fractures seen in the hospital emergency department. Of these, over 40% are considered unstable and require some form of fixation. In recent years with the advent of low profile plating, open reduction and internal fixation (ORIF) using volar plates has become the surgical treatment of choice in many hospitals. However, it is currently unknown which plating system has the lowest complication rate and/or superior clinical and radiological outcomes following surgery. Few studies have compared different types of plates, which may have various features, different plate and screw designs or may be manufactured from different materials (for example, stainless steel or titanium). This study will specifically investigate and compare the clinical and radiological outcomes and complication rates of two commonly used volar plating systems for fixation of distal radius fractures: one made from stainless steel (Trimed™ Volar Plate, Trimed™, California, USA) and the other made from titanium (Medartis® Aptus Volar Plate, Medartis®, Basel, Switzerland). The primary aim of this study is to determine if there is a difference on the Patient Reported Wrist Evaluation six months following ORIF using a volar plate for adult patients with a distal radius fracture.Methods/DesignThis study will implement a randomized prospective clinical trial study design evaluating the outcomes of two different types of volar plates: one plate manufactured from stainless steel (Trimed™ Volar Plate) and one plate manufactured from titanium (Medartis® Aptus Volar Plate). The surgery will be performed at a major trauma hospital in Brisbane, Australia. Outcome measures including function, adverse events, range of movement, strength, disability, radiological findings and health-related quality of life will be collected at 6 weeks, 3, 6, 12 and 24 months following surgery. A parallel economic analysis will also be performed. This randomized clinical trial is due to deliver results in December 2016.DiscussionResults from this trial will contribute to the evidence on operative management of distal radius fractures and plate material type.Trial registrationACTRN12612000969864
