RESUMEN

OBJECTIVE: Aims were to (i) report prevalence and (ii) evaluate reliability of the radiographic findings in examinations of patients suspected of subacromial impingement syndrome (SIS), performed before a patient's first consultation at orthopaedic department. MATERIALS AND METHODS: This cross-sectional study examined radiographs from 850 patients, age 18 to 63 years, referred to orthopaedic clinic on suspicion of SIS. Prevalence (%) of radiographic findings were registered. Inter- and intrarater reliability was analysed using expected and observed agreement (%), kappa coefficients, Bland-Altman plots, or intraclass coefficients. RESULTS: A total of 850 patients with a mean age of 48.2 years (SD = 8.8) were included. Prevalence of the radiographic findings was as follows: calcification 24.4%, Bigliani type III (hooked) acromion 15.8%, lateral/medial acromial spurs 11.1%/6.6%, acromioclavicular osteoarthritis 12.0%, and Bankart/Hill-Sachs lesions 7.1%. Inter- and intrarater Kappa values for most radiographic findings ranged between 0.40 and 0.89; highest values for the presence of calcification (0.85 and 0.89) and acromion type (0.63 and 0.66). The inter- and intrarater intraclass coefficients ranged between 0.41 and 0.83; highest values for acromial tilt (0.79 and 0.83) and calcification area (0.69 and 0.81). CONCLUSION: Calcification, Bigliani type III (hooked) acromion, and acromioclavicular osteoarthritis were prevalent findings among patients seen in orthopaedic departments on suspicion of SIS. Spurs and Bankart/Hill-Sachs lesions were less common. Optimal reliabilities were found for the presence of calcification, calcification area, and acromial tilt. Calcification qualities, acromion type, lateral spur, and acromioclavicular osteoarthritis showed suboptimal reliabilities. Newer architectural measures (acromion index and lateral acromial angle) performed well with respect to reliability.

RESUMEN

INTRODUCTION: Perioperative glycaemic control is important. However, the complexity of guidelines for perioperative diabetes management is complicated due to different and novel antihyperglycaemic medications, limited procedure-specific data and lack of data from implemented fast-track regimens which otherwise are known to reduce morbidity and glucose homeostasis disturbances. Consequently, outcome in patients with diabetes mellitus (DM) after surgery and the influence of perioperative diabetes management on postoperative recovery remains poorly understood. METHODS AND ANALYSIS: A prospective observational multicentre study involving 8 arthroplasty centres across Denmark with a documented implemented fast-track programme (median length of hospitalisation (LOS) 1 day). We will collect detailed perioperative data including preoperative haemoglobin A1c and antidiabetic treatment in 1400 unselected consecutive patients with DM undergoing hip and knee arthroplasty from September 2022 to December 2025, enrolled after consent. Follow-up duration is 90 days after surgery. The primary outcome is the proportion of patients with DM with LOS >4 days and 90-day readmission rate after fast-track total hip arthroplasty (THA), total knee arthroplasty (TKA) and unicompartmental knee arthroplasty (UKA). The secondary outcome is the association between perioperative diabetes treatment and LOS >2 days, 90-day readmission rate, other patient demographics and Comprehensive Complication Index for patients with DM after THA/TKA/UKA in a fast-track regimen. ETHICS AND DISSEMINATION: The study will follow the principles of the Declaration of Helsinki and ICH-Good Clinical Practice guideline. Ethical approval was not necessary as this is a non-interventional observational study on current practice. The trial is registered in the Region of Southern Denmark and on ClinicalTrials.gov. The main results and all substudies of this trial will be published in peer-reviewed international medical journals. TRIAL REGISTRATION NUMBER: NCT05613439.

RESUMEN

PURPOSE: The most used cup designs for trapeziometacarpal (TMC) arthroplasty are of hemispherical and conical geometrical shape. Using a validated pig bone model, we compared the bone fixation using radiostereometry (RSA). METHODS: Twenty saddle-shaped pig forefoot bones were prepared with insertion of bone markers and reaming. Hemispherical Type T cups (Beznoska, Kladno, Czech Republic) (N = 10) and conical Moovis cups (Stryker, Pusignan, France) (N = 10) of 9-mm diameter were inserted press-fit. The bones were fixed in cement blocks for stability, and the cups were loaded in a motorized test stand. First, a low-pressure cyclic load test (0-150N) with 130 compression cycles was performed. Next, a push-in test of progressive loads with 50N increments (range: 150-900N) was applied until a visual change in cup position appeared. Cup migration was evaluated with RSA after every new load application. Cup failure was defined as total translation > 0.5 mm between two load applications. RESULTS: Both cup types tolerated a compression load of 450 N without failure. Beyond this load level, the total translation cup migration of mean 0.20 mm (95% CI 0.11; 0.30) for the Type T group was higher than mean 0.10 mm (95% CI 0.06; 0.15) of the Moovis group (p = 0.046). The Hazard ratio for failure was 0.52 (95% CI 0.12; 2.17) (p = 0.37), indicating that the risk of failure was two-fold higher in the Type T group. CONCLUSION: We conclude that conical TMC cups have superior fixation as compared to hemispherical cups above a loading level of 450 N, which correspond to a 3.8 kg tip-pinch. In a clinical perspective, based on the fixation strength of both cup types, it seems safe to allow light-load activities of daily living such as buttoning a shirt and using a key shortly after surgery and until sufficient osseointegration is achieved.

RESUMEN

INTRODUCTION: Cut-out is the most frequently reported mechanical failure of internal fixation of pertrochanteric fractures. The purpose of this study was to examine if hydroxyapatite-coated screw thread on a sliding hip screw (SHS) could reduce screw migration within the femoral head in patients with stable pertrochanteric fractures. MATERIALS AND METHODS: In a double-blinded randomized controlled study, 37 patients at mean age 78 (range 56-96), with pertrochanteric fracture (Evans I, II, IV) received surgery with a SHS with a hydroxyapatite-coated or a non-coated lag screw thread. Radiostereometry and standard radiographs were obtained 1 day, 6 weeks, 3- and 6 months post-operatively to evaluate screw and fracture migration and fracture reposition. The two groups were combined to describe fracture migration. RESULTS: There was similar and small screw migration in the femoral head between the two groups at 6 weeks, 3- and 6 months (p > 0.12). Fracture migration occurred predominantly in the first 6 weeks, where fracture impaction was 5.95 mm (CI 95% 2.87 to 9.04) and anterior rotation of the femoral head was -2.94° (CI 95% - 5.22 to - 0.66). Migration of the fracture (total translation) correlated to the post-operative fracture reposition (p = 0.002), but not significantly to screw migration (p = 0.09). Neither screw total translation (rho 0.06, p = 0.79) nor fracture total translation (rho 0.04, p = 0.77) correlated with bone mineral density. CONCLUSION: There was no clinical benefit of hydroxyapatite coating on lag screw migration in this patient cohort. Migration of the pertrochanteric fractures was higher with poor fracture reposition but fractures generally stabilized after 6 weeks follow-up. The study was registered at ClinicalTrials.gov (NCT05677061). LEVEL OF EVIDENCE II: Patient-blinded prospective randomized study. Trial registration number The study was registered at ClinicalTrials.gov (NCT05677061).

RESUMEN

BACKGROUND AND PURPOSE: Limited data exists on the implementation process and safety of discharge on the day of surgery after primary hip and knee arthroplasty in a multicenter setting. We report our study protocol on the investigation of the feasibility, safety, and socioeconomic aspects following discharge on day of surgery after hip and knee arthroplasty across 8 fast-track centers. PATIENTS AND METHODS: This is a study protocol for a prospective cohort study on discharge on day of surgery from the Center for Fast-track Hip and Knee Replacement. The collaboration includes 8 centers covering 40% of the primary hip and knee arthroplasty procedures undertaken in Denmark. All patients scheduled for surgery are screened for eligibility using well-defined inclusion and exclusion criteria. Eligible patients fulfilling discharge criteria will be discharged on day of surgery. We expect to screen 9,000 patients annually. Duration and outcome: Patients will be enrolled over a 3-year period from September 2022 and reporting of results will run continuously until December 2025. We shall report the proportion of eligible patients and patients discharged on day of surgery as well as limiting factors. Readmissions and complications within 30 days are recorded with real-time follow-up by research staff. Furthermore, patient-reported information on willingness to repeat discharge on day of surgery, contacts with the healthcare system, complications, and workability is registered 30 days postoperatively. EQ-5D, Oxford Knee Score, and Oxford Hip Score are completed preoperatively and after 3 months and 1 year. Finally, outcome data will be used in the development of a prediction model for successful discharge on the day of surgery.

RESUMEN

PURPOSE: This study evaluated the hypothesis that higher occupational hand force requirements are related to slower return to work (RTW) after surgery for trapeziometacarpal joint osteoarthritis. METHODS: Patients treated surgically for trapeziometacarpal joint osteoarthritis from 2001 to 2017 were identified in the Danish National Patient Register. Sustainable RTW (sRTW) was defined as the first period of 4 consecutive weeks without health-related public transfer payments, according to the Danish National Register on Public Transfer Payments. Occupational codes from the Danish Employment Classification Module were linked to a hand-arm job exposure matrix to obtain occupational hand force requirements for each patient. Cox regression models were used to analyze time until sRTW in relation to hand force requirements with adjustment for age, sex, type of surgery, preoperative sick leave, and calendar year of surgery. RESULTS: The study included 2,090 patients. Within 104 weeks, 91% sustainably returned to work. The percentage of individuals in the subgroups that did not RTW was 8% of low-force- and medium-force-exposed patients and 14% of high-force-exposed patients. Medium and high occupational hand force requirements were associated with slower sRTW. The adjusted hazard ratio for sRTW was 0.84 (95% confidence interval, 0.74-0.95) for medium and 0.59 (95% confidence interval, 0.50-0.68) for high compared with low hand force requirements. Among patients who returned to work, patients with medium and high hand force requirements had median periods until sRTW of 16 and 18 weeks, respectively, compared with 10 weeks among patients with low hand force requirements. CONCLUSIONS: The prognosis regarding RTW after surgery for trapeziometacarpal joint osteoarthritis is generally good, but patients with higher occupational hand force requirements can expect slower RTW. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic II.

RESUMEN

PURPOSE: New total knee arthroplasty implant designs attempt to normalize kinematics patterns that may improve functional performance and patient satisfaction. It was hypothesized that a more medial congruent (MC) anatomic bearing design (1) influences the tibiofemoral kinematics and (2) enhances articular congruency compared to a standard symmetrical cruciate retaining (CR) bearing design. METHODS: In this double-blinded randomized study, 66 patients with knee osteoarthritis were randomly included in two groups: MC (n = 31) and CR (n = 33). Clinical characteristics such as knee ligament lesions and knee osteoarthritis scores were graded on preoperative magnetic resonance imaging and radiography. At the 1-year follow-up, dynamic radiostereometric analysis was used to assess tibiofemoral joint kinematics and articulation congruency. Patient-reported outcome measures, Oxford Knee Score, the Forgotten Joint Score, and the Knee Osteoarthritis Outcome Score, were assessed preoperatively and at the 1-year follow-up. RESULTS: Compared to the CR bearing, the MC bearing displayed an offset with approximately 3 mm greater anterior tibial drawer (p < 0.001) during the entire motion, and up to approximately 3.5 degrees more tibial external rotation (p = 0.004) from mid-swing to the end of the gait cycle at the 1-year follow-up. Furthermore, the congruency area in the joint articulation was larger during approximately 80% of the gait cycle for the MC bearing compared to the CR. The patient-reported outcome measures improved (p < 0.001), but there were no differences between groups. In addition, there were no differences in clinical characteristics and there were no knee revisions or recognized deep infections during follow-up. CONCLUSION: The study demonstrates that the MC-bearing design changes tibiofemoral kinematics and increases the area of congruency towards more native knee kinematics than the CR bearing. In perspective this may contribute to a more stabilized knee motion, restoring the patient's confidence in knee function during daily activities.

RESUMEN

INTRODUCTION: Hip fracture patients are fragile, and the majority fail to fully recover to their pre-fracture functional level, resulting in an increase in institutionalization. We aimed to investigate risk factors for being dependent at discharge and for failure to return to independent living 12 months after a hip fracture. MATERIALS AND METHODS: From 2011 to 2017, all surgically treated hip fracture patients admitted from their own homes were included in this prospective cohort study. Patient characteristics were registered, including age, sex, lifestyle, comorbidities, pre-fracture New Mobility Score (NMS), biochemical measures, fracture type, and surgical method. Dependency was measured at discharge using a cumulated ambulatory score (CAS < 6) and the timed-up-and-go test (TUG > 20 s). At 12 months, patients were interviewed regarding residence, NMS, and care needs. Multivariable logistic regression was used, reporting odds ratio (OR) with 95% confidence intervals (CI). RESULTS: A total of 2006 patients were included in the study with data regarding their hospital stay and discharge. In all, 1342 patients underwent follow-up at 12 months. The risk factors found to be associated with dependency at discharge were mostly static. Modifiable variables associated with dependency at discharge (CAS < 6) were hypoalbuminemia (OR: 1.94, 95% CI 1.38-2.71), not having been mobilized to standing within 24 h (OR: 1.88, 95% CI 1.12-3.15), and general anesthesia (OR: 1.35, 95% CI 1.07-1.71). Failure to return to independent living at 12 months was found in 10% of the patients, and was primarily associated with patient characteristics and proxy variables for comorbidities, but also with dependency at discharge (CAS < 6). CONCLUSIONS: Mobilizing patients to standing within 24 h from hip fracture surgery was vital in maximizing short-term functional recovery. Failure to return to independent living was seen in the frailest patients. However, the majority remained in their own home with little increase in care needs.

RESUMEN

BACKGROUND: The aim of this prospective study was to investigate bone mineral density (BMD) changes in the proximal humerus of the shoulder during a healing period of 12 months after displaced 3- or 4-part proximal humerus fractures treated with open reduction and internal fixation (ORIF) with an anatomic angular stable locking plate and the influence on fracture healing and functional outcomes. METHODS: In a prospective multicenter study, 36 patients (29F and 7M, age range: 38-83) with unilateral displaced 3- or 4-part proximal humerus fractures were included for ORIF. Dual-energy x-ray absorptiometry for osteoporosis status was employed. Postoperative and 6-week, 3-, 6-, and 12-month shoulder radiographs and dual-energy x-ray absorptiometry of the shoulder with BMD measures in 4 templated regions of interest (ROIs) were performed. Functional outcomes, Western Ontario Osteoarthritis of the Shoulder index, Constant score, visual analog scale pain (VAS), and 36-Item Short Form Survey, were collected. RESULTS: A total of 17 of 36 patients had osteoporosis. We found no differences in BMD changes, functional outcomes, radiology, or need for revision surgery between the osteoporosis and nonosteoporosis groups. The BMD values gradually declined from baseline to 3-month follow-up in all 4 ROIs of the operated shoulders. All 4 ROIs in the operated shoulder presented with a reduction in BMD at 3, 6, and 12 months compared with baseline, whereas no significant BMD changes were seen in the healthy shoulder during the study period. The functional outcomes displayed an increase in Constant score from 3 to 12 months, but a decrease in domains of the 36-Item Short Form Survey from preinjury to 12 months (physical functioning, general health, and bodily pain). Preinjury and 12-month Western Ontario Osteoarthritis of the Shoulder index, VAS pain at rest, and VAS pain at activity were comparable. CONCLUSION: BMD changes appeared swiftly in the proximal humerus, after the treatment of displaced 3- or 4-part fractures with ORIF, particularly affecting the proximal diaphysis of the humerus. Shoulder function was restored to preinjury levels for most of the patients. Osteoporosis may not be regarded as a contraindication for the treatment of displaced 3- or 4-part fractures with ORIF.

RESUMEN

BACKGROUND AND PURPOSE: Dual mobility (DM) articulation total hip arthroplasty (THA) is used increasingly to reduce dislocation risk. We investigated cup fixation, polyethylene (PE) wear, serum chromium and cobalt ions, and their correlation to physical activity in patients with DM cups at 6-year follow-up. PATIENTS AND METHODS: In a patient-blinded RCT, 60 patients with hip osteoarthritis at a median age of 74 years (70-82) were randomly allocated to cemented (n = 30) or cementless hydroxyapatite-coated (n = 30) fixation of Avantage DM THA with a highly-crosslinked vitamin-E PE liner. Cup migration and PE wear were measured with radiostereometric analysis (RSA), chromium and cobalt ions were measured in serum, and physical activity was measured with accelerometers. RESULTS: At 6-year follow-up, proximal cup migration was similar: 0.14 mm (95% CI 0.01-0.28) for cemented cups and 0.21 mm (0.02-0.39) for cementless cups. The PE wear rate from 1- to 6-year follow-up was also similar: 0.06 mm/year (0.04-0.09) for cemented cups and 0.07 mm/year (0.04-0.11) for cementless cups. Serum metal ion levels were undetectable or very low. Physical activity was mainly low intensity and did not correlate to PE wear rate or cup migration. CONCLUSION: Cemented and cementless DM cups with highly crosslinked vitamin-E infused liners have similar cup migration and PE wear when used for primary THA surgery.

RESUMEN

BACKGROUND: Patients with unilateral hip osteoarthritis appear to have between-leg differences in leg extension power (LEP). The Nottingham Leg Extensor Power Rig provides reliable and valid results but requires sensitive equipment. It would be relevant to identify measures closely associated with this test. OBJECTIVE: (i) To investigate if LEP is lower in the affected leg compared to the non-affected leg. Furthermore, to investigate the associations between LEP and the measures: (ii) Functional performance, (iii) accelerometer-based measurement of physical activity and (iv) patient-reported outcome measures (PROM). DESIGN: Cross-sectional study including 60 patients (30 men, 30 women) with hip osteoarthritis scheduled for hip replacement. METHOD: The counter movement jump and 10-m sprint tests were used to determine functional performance, accelerometer-sensors were used to determine physical activity and the Copenhagen Hip and Groin Outcome Score (HAGOS) was used to determine PROM. RESULTS: (i) LEP in the affected leg corresponded to 79% [95% CI 74%; 85%] of the non-affected leg, (ii) LEP was positively associated with functional performance tests (ß 0.63 to 0.78, p < 0.05), (iii) positively associated although non-significantly with physical activity (ß 0.16 to 0.23, p > 0.05) and (iv) positively associated with the six HAGOS subscales (ß 0.25 to 0.54, p < 0.05). CONCLUSION: Functional performance tests may be used as feasible, inexpensive and fast ways to assess LEP in clinical settings. These results may suggest that interventions aimed at improving LEP can improve functional performance and PROM, but not physical activity. Future research is needed to confirm the causality of these cross-sectional findings. THE CLINICAL TRIAL REGISTRATION NUMBERS: Danish Data Protection Agency (1-16-02-640-14), ClinicalTrials.gov (NTC02301182) and approved by the Danish Biomedical Research Ethics Committee (1-10-72- 343-14) prior to data collection.

RESUMEN

Background Measurement of in vivo distal radioulnar joint (DRUJ) pathomechanics during simple activities can represent the disability experienced by patients and may be useful in diagnostics of DRUJ instability. A first step is to describe the physiological normal limits for DRUJ kinematics in a reproducible and precise test setup, which was the aim of this study. Methods DRUJ kinematics were evaluated in 33 participants with dynamic radiostereometry (RSA) while performing a standardized press test examination. AutoRSA software was used for image analyses. Computed tomography (CT) forearm bone models were generated, and standardized anatomical axes were applied to estimate kinematic outcomes including, DRUJ translation, DRUJ position ratio, and changes in ulnar variance. Repeatability of dynamic RSA press test double examinations was evaluated to estimate the precision and intraclass correlation coefficient (ICC) test-retest agreement. Results The maximum force during the press test was 6.0 kg (95% confidence interval [CI]: 5.1-6.9), which resulted in 4.7 mm (95% CI: 4.2-5.1) DRUJ translation, DRUJ position ratio of 0.40 (95% CI: 0.33-0.44), and increase in ulnar variance of 1.1 mm (95% CI: 1.0-1.2). The mean maximum DRUJ translation leveled off after a 5 kg force application. The DRUJ translation ICC coefficient was 0.93 within a prediction interval of ± 0.53mm. Conclusions This clinical study demonstrates the normal values of DRUJ kinematics and reports excellent agreement and high precision of the press tests examination using an automated noninvasive dynamic RSA imaging method based on patient-specific CT bone models. The next step is the application of the method in patients with arthroscopic verified triangular fibrocartilage complex injuries. Level of Evidence This is a Level IV, case series study.

RESUMEN

AIM: To investigate the impact of delay in surgery for medical causes and active clinical issues (ACIs) on 30-day readmission for medical causes after hip fracture surgery. FINDINGS: ACIs were associated with readmissions following hip fracture surgery; however, no association between readmissions and reasons for delaying surgery was found. MESSAGE: Further studies into ACIs and reasons for delaying surgery are warranted to make more tailor-made treatment plans for patients with hip fracture.

RESUMEN

OBJECTIVE: To investigate if using a hip bandage is more effective than standard care in the prevention of total hip arthroplasty re-dislocation in patients with a previous total hip arthroplasty dislocation. DESIGN: randomized controlled trial. SETTING: Holstebro Regional Hospital and Viborg Regional Hospital. SUBJECTS: A total of 99 patients, 51 women, mean 70.7 (SD 9.9) years were enrolled in an un-blinded, clinical randomized controlled trial. INTERVENTIONS: Participants with at least one previous total hip arthroplasty dislocation were randomized to either wearing a bandage reducing flexion, adduction, and internal rotation of the hip (intervention group) or to standard care (control group). The participants were followed for 12 weeks. Main follow-up measures were as follows: number of re-dislocations (primary outcome), hip disability measured with the Oxford Hip Score (0-48, 48 best), quality of life measured with the 36-Item Short Form Survey (0-100, 100 best), satisfaction with treatment and serious adverse events. Statistical analyses followed the intention-to-treat principle. RESULTS: No significant group differences were observed for the primary outcome re-dislocations (9 versus 15, P = 0.143) or for disability (11.3 versus 14.4, P = 0.161), quality of life (57.7 versus 48.3, P = 0.050) or satisfaction with treatment (P = 0.562). There were 3 serious adverse events leading to total hip arthroplasty revision in the intervention group and 4 in the control group. CONCLUSION: We found that a hip bandage is not superior to standard care in the prevention of total hip arthroplasty re-dislocation in those with a previous total hip arthroplasty dislocation.

RESUMEN

PURPOSE: Despite extensive research, a complete understanding of factors influencing mortality risk after hip fractures is lacking. Previous research has focused on static risk factors; however, to improve outcomes, attention should be directed towards risk factors that may be optimised. The present study aimed to investigate the association of 19 risk factors with mortality among patients with hip fracture treated according to a well-defined guideline. METHODS: The study was a retrospective analysis of a large prospective patient cohort with all consecutive patients surgically treated for a hip fracture from January 2011 to December 2017 included (n = 2800). Variables were obtained from patient records and the Holstebro Hip Fracture Database comprising prospectively registered data on demographics, comorbidity, malnutrition (low Body Mass Index (BMI) or albumin) and hospital stay (including fracture and surgical data, biochemistry, mobilisation and discharge). Outcomes were 30-day and one-year mortality. RESULTS: Patients were predominantly female (66%); median age 81.6 years. Overall mortality was 9% at 30 days and 24% at one year. Age ≥ 75 years, male gender, nursing home residence, cognitive impairment, American Society of Anesthesiologists (ASA) score ≥ 3, BMI < 20 kg/m2, albumin < 35 g/l, creatinine ≥ 100 µmol/l, a low New Mobility Score and no mobilisation were all associated with increased mortality at 30 days and one year. CONCLUSION: In addition to non-modifiable risk factors, comorbidities (expressed as high ASA score and creatinine), malnutrition, and failure to achieve early post-operative mobilisation were associated with increased short and long-term mortality among patients with hip fracture: these are potentially modifiable. The effect of optimisation interventions warrants further research.

RESUMEN

BACKGROUND AND AIMS: Patient reported outcome measures are often used in medical research to evaluate symptoms and functional status in patients. The Boston Carpal Tunnel Questionnaire is specifically designed to evaluate functional status and symptom severity in patients with Carpal Tunnel Syndrome. The aim of this study was to validate and examine the measurement properties of the Functional Status Scale and Symptom Severity Scale from the Danish translated Boston Carpal Tunnel Questionnaire. MATERIAL AND METHODS: We analyzed 88 prospectively enrolled patients in the validity and responsiveness group and 31 prospectively enrolled patients in the reliability group. Patients in the validity and responsiveness group answered the Quick Disabilities of the Arm, Shoulder and Hand Questionnaire and the Danish translated Boston Carpal Tunnel Questionnaire preoperatively and after surgery. Patients in the responsiveness group answered the same questionnaire two times prior to surgery. RESULTS: Responsiveness of the two subscales were high (Effect Size 0.99/1.76; Standardized Response Mean 0.86/1.50). Correlation to the Danish validated QuickDASH was high (rho 0.75/0.89). Test-retest reliability was high (ICC 0.94/0.90) and the internal consistency was high (Cronbach's alpha 0.93/0.92). CONCLUSION: Our study shows satisfactory results of both subscales of the Danish translated Boston Carpal Tunnel Questionnaire. This makes it highly useful when conducting research on patients with Carpal Tunnel Syndrome. TRIAL REGISTRATION: The Danish Data Protection Agency: jr. nr. 2007-58-0010.

RESUMEN

PURPOSE: We aimed to determine the prognosis after trapeziometacarpal total joint arthroplasty for basal thumb osteoarthritis with respect to sustainable return to work (RTW), pain, and disability. Our main hypothesis was that high occupational hand force requirements are related to slower RTW. METHODS: We conducted a 12-month follow-up study of patients who were treated with a trapeziometacarpal total joint arthroplasty in 2003 to 2015 and were active in the labor market at the time of surgery. We used registry information about RTW. Before surgery and at the 12-month follow-up, we obtained data on pain and disability. To obtain estimates of occupational hand force requirements for individual patients, we linked the patients' self-reported job title to a job exposure matrix based on experts' ratings. We used Cox regression models to analyze the time until sustainable RTW and logistic regression models to analyze pain and disability. RESULTS: A total of 133 patients were included. Most patients returned to work within 12 months after surgery (86%). For those who returned to work within 12 months (n = 114), mean time until sustainable RTW was 14 weeks (SD, 9 weeks). Higher hand force requirements were associated with slower RTW (for medium- and high-force requirements, adjusted hazard ratios were 0.48 [95% confidence interval, 0.30-0.78] and 0.41 [95% confidence interval, 0.25-0.69]). Occupational hand force requirements were not associated with pain and disability at follow-up. CONCLUSIONS: High occupational hand force requirements were associated with slower RTW, but not with pain and disability 12 months after surgery. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic I.

RESUMEN

PURPOSE: Symptomatic instability of the distal radioulnar joint (DRUJ) caused by lesion of the Triangular Fibrocartilage Complex (TFCC) can be treated with a number of surgical techniques. Clinical examination of DRUJ translation is subjective and limited by inter-observer variability. The aim of this study was to compare the stabilizing effect on DRUJ translation with two different surgical methods using the Piano-key test and a new precise low-dose, non-invasive radiostereometric imaging method (AutoRSA). METHODS: In a randomized experimental study we evaluated the DRUJ translation in ten human cadaver arms (8 males, mean age 78 years) after cutting the proximal and distal TFCC insertions, and after open surgical TFCC reinsertion (n = 5) or TFCC reconstruction using a palmaris longus tendon graft ad modum Adams (n = 5). The cadaver arms were mounted in a custom-made fixture for a standardized Piano-key test. Radiostereometric images were recorded and AutoRSA software was used for image analyses. Standardised anatomical axes and coordinate systems of the forearm computer tomography bone models were applied to estimate DRUJ translation after TFCC lesions and after surgical repair. RESULTS: The DRUJ translation after cutting the proximal and distal TFCC insertions was 2.48 mm (95% CI 1.61; 3.36). Foveal TFCC reinsertion reduced DRUJ translation by 1.78 mm (95% CI 0.82; 2.74, p = 0.007), while TFCC reconstruction reduced DRUJ translation by 1.01 mm (95% CI -1.58; 3.60, p = 0.17). CONCLUSION: In conclusion, foveal TFCC reinsertion significantly decreased DRUJ translation while the stabilizing effect of Adams TFCC reconstruction was heterogeneous. This supports the clinical recommendation of TFCC reinsertion in patients suffering from symptomatic DRUJ instability due to acute fovea TFCC lesions.
