Functional outcomes after open reduction and internal fixation for treatment of displaced distal radius fractures in patients over 60 years of age

Non-surgical vs. surgical treatment of distal radius fractures: a meta-analysis of randomized controlled trials

PURPOSE

To compare the clinical outcomes between nonsurgical and surgical treatment of distal radius fracture.

METHODS

We performed a systematic literature search by using multiple databases, including Medline, PubMed, and Cochrane. All databases were searched from the earliest records through February 2023. The study compared nonsurgical versus surgical treatment of distal radius fractures and included only randomized controlled trials (RCTS).

RESULTS

There were seventeen randomized controlled trials retrieved. A total of 1730 patients were included: 862 in the nonsurgical group and 868 in the surgical group. The results showed a significant reduction in DASH score with surgical treatment (WMD 3.98, 95% CI (2.00, 5.95), P < 0.001). And in grip strength (%), the results showed a significant improvement in surgical treatment compared with non-surgical treatment (WMD - 6.60, 95% CI (-11.61, -1.60), P = 0.01). There was significant difference in radial inclination, radial length, volar title, range of wrist pronation, range of wrist supination. However, no difference in radial deviation, ulnar deviation, ulnar variance, range of wrist extension and range of wrist flexion was observed.

CONCLUSIONS

The results of this meta-analysis suggest that some patients with surgical treatment of distal radius fractures not only improved the grip strength (%), decreased the DASH score, but also improved the range of wrist pronation and the range of wrist supination compared with nonsurgical treatment. Based on the present meta-analysis, we suggest that some patients with surgical treatment might be more effective in patients with distal radius fracture.

The Effect of Age and Sex on Early Postoperative Outcomes after Surgical Treatment of Distal Radius Fractures

Background: We aim to evaluate the impact of advanced age and sex on postoperative complications and radiographic outcomes after open reduction with internal fixation of distal radius fractures (DRF). Methods: We conducted a retrospective chart review, including all patients who underwent open reduction with internal fixation of a DRF between 2012 and 2018 at a single level 1 trauma centre. We recorded patient age, sex, fracture classification (Arbeitsgemeinschaft für Osteosynthesefragen/Orthopaedic Trauma Association [AO/OTA]), time from injury to surgical date, surgical duration, diabetes status, tobacco use, illicit drug use, history of osteoporosis, use of adjuvants, fixation type, postoperative radiographic restoration of normal parameters and early complications including loss of reduction within 30 days postoperatively. Advanced age was defined as age greater than 60 years. Results: A total of 521 patients underwent operative treatment - 264 males and 257 females. Males were twice as likely (23.5% vs. 10.1%; p < 0.0001) to sustain a type C3 fracture and be treated with a wrist spanning plate (5.3% vs. 0; p < 0.0001). A larger percentage of elderly patients undergoing operative treatment of DRF were female (20.2% vs. 5.7%; p < 0.0001) and females were more likely to carry a pre-injury diagnosis of osteoporosis (9.3% vs. 0%; p < 0.0001). And 100% of the elderly patients received were treated with a volar plate. The overall early loss of reduction was 7.5%. The overall complication rate was 8.2%. No differences in early postoperative complications were identified between sexes or age groups. Neither female sex nor advanced age was found to have increased risk of postoperative complications or early loss of reduction. Similar postoperative radiographic parameter measurements were obtained across groups as well. Conclusions: Our results support the idea that operative treatment of unstable DRF in elderly patients and women is a reasonable treatment option without significant increases in early postoperative complications. Level of Evidence: Level III (Therapeutic III).

Home exercises after volar locking plate fixation for distal radius fracture in the elderly are as effective as supervised physiotherapy -multicenter retrospective study

BACKGROUND

Although home exercises are used for postoperative rehabilitation of distal radius fractures (DRF), the superiority of home exercise over supervised physiotherapy rehabilitation is controversial. This study aimed to compare the function of home exercise and supervised physiotherapy rehabilitation during postoperative rehabilitation for DRF.

METHODS

We conducted a multicenter, retrospective study in which we included 1949 patients over 65 years old who underwent volar locking plate fixation for DRF. After propensity score matching, 308 patients were assigned to each of an independent home exercise group (IHG) and supervised physiotherapy group (SPG). Wrist function was assessed after 3, 6, and 12 months postoperatively.

RESULTS

The results showed that the Mayo Wrist Score did not differ significantly within the observation period. Range of motion of the wrist was better in the SPG up to 3 months postoperatively but was almost the same as that in the IHG at 6 months. However, the Numerical Rating Scale score was lower in the IHG during all observation periods.

CONCLUSIONS

Home exercise may be as effective as supervised physiotherapy in the medium term, but supervised physiotherapy rehabilitation should be considered if early recovery and good wrist function are desired.

Treatment of Distal Radius Fractures in Women Older than 80 Years: A Preliminary Report of Functional and Radiographic Outcomes after Open Reduction and Internal Fixation

Background  Distal radius fractures are one of the most common fractures seen in the elderly. The management of distal radius fractures in the elderly, especially patients older than 80 years, has not been well defined. The purpose of this study was to evaluate operative treatment of distal radius fractures in patients older than 80 years to determine functional outcomes and complication rates. Materials and Methods  A retrospective review was performed to identify patients 80 years or older who were treated for a distal radius fracture with open reduction and internal fixation (ORIF). Medical records were reviewed for demographics, medical history, functional outcomes including quick Disabilities of the Arm, Shoulder, and Hand (qDASH), radiographs, and postoperative complications. Results  There were 40 patients included for review. Average age was 84 years. The preoperative qDASH score was 69. At 6 months follow-up, the postoperative qDASH score was 13 ( p  < 0.001). There were five (12.5%) complications reported postoperatively. All fractures healed with adequate radiographic alignment and there were no hardware failures. Conclusion  Distal radius fractures in patients older than 80 years treated with ORIF have good functional outcomes and low complication rates. Increased functionality and independence of the elderly, as well as updated implant design can lead to the effective surgical management of these patients. When indicated from a clinical perspective, operative fixation of distal radius fractures should be considered in patients older than 80 years.

Comparison of above elbow and below elbow immobilisation for conservative treatment of distal end radius fracture in adults: A systematic review and meta-analysis of randomized clinical trials

PURPOSE

The aim of this study was to analyze if any difference exists on the type of immobilisation (above elbow vs. below elbow) in the conservative treatment of distal end radius fractures in adults.

METHODS

The study was performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-analyses. An electronic literature search was performed up to 1st October 2021 in Medline, Embase, Ovid and Cochrane database using the search terms, "distal end radius fractures OR fracture of distal radius", "conservative treatment OR non-surgical treatment", "above elbow immobilisation" and "below elbow immobilisation". Randomized clinical trials written in English, describing outcome of distal end radius fractures in adults by conservative or non-surgical means using above elbow immobilisation or below elbow immobilisation were included and assessed according to the risk of bias assessment (RoB2) tool by Cochrane collaboration. Non-randomized clinical trials, observational studies, retrospective studies, review articles, commentaries, editorials, conference presentations, operative techniques and articles without availability of full text were excluded from this review. The meta-analysis was performed using Review Manager version 5.4.1 (The Cochrane Collaboration, Copenhagen, Denmark).

RESULTS

Six randomized clinical trials were included for quantitative review. High heterogeneity (I² >75%) was noted among all the studies. The standard mean difference between the disability of the arm, shoulder and hand scores in both the groups was 0.52 (95% CI (-0.28)-1.32) which was statistically non-significant. There was no statistical difference in the radial height (mean difference 0.10, 95% CI (-0.91)-1.12), radial inclination (mean difference 0.5, 95% CI (-1.88)-2.87), palmar tilt (mean difference 1.06, 95% CI (-0.31)-2.43) and ulnar variance (mean difference 0.05, 95% CI (-0.74)-0.64). It was observed that shoulder pain occurred more commonly as a complication in above elbow immobilisation and the values were statistically significant (above elbow: 38/92, 41.3%; below elbow: 19/94, 20.2%).

CONCLUSION

This two-armed systematic review on the above elbow or below elbow immobilisation to be used for conservative treatment of the distal end radius fracture in adults resulted in non-significant differences in terms of functional and radiological scores among the two groups but significant increase in the complication rates in the above elbow group.

Volar locking plate vs cast immobilization for distal radius fractures: a systematic review and meta-analysis

Introduction

Materials and methods

Results

Conclusions

Grip Strength Measurement for Outcome Assessment in Common Hand Surgeries

Grip strength has been used to evaluate the upper extremity functional status and clinical outcomes following upper extremity trauma or surgery. Understanding general recovery patterns of grip strengthening can be helpful in assessing the patients’ recovery status and in assisting in preoperative consultations regarding expectations for recovery. We summarize related studies on grip strength measurement and recovery patterns in common hand conditions, including carpal tunnel syndrome, cubital tunnel syndrome, triangular fibrocartilage complex injury, and distal radius fractures.

Treatment options in extra-articular distal radius fractures: a systematic review and meta-analysis

PURPOSE

This systematic literature review aimed to make a detailed overview on the clinical and functional outcomes and to get insight into the possible superiority of a treatment method for extra-articular distal radius fractures.

METHODS

Embase, Medline, Cochrane Library, Web of Science, and Google Scholar were searched for studies describing treatment results. Five treatment modalities were compared: plaster cast immobilization, K-wire fixation, volar plating, external fixation, and intramedullary fixation.

RESULTS

Out of 7,054 screened studies, 109 were included in the analysis. Overall complication rate ranged from 9% after plaster cast treatment to 18.5% after K-wire fixation. For radiographic outcomes, only volar tilt in the plaster cast group was lower than in the other groups. Apart from better grip strength after volar plating, no clear functional differences were found across treatment groups.

CONCLUSION

Current literature does not provide uniform evidence to prove superiority of a particular treatment method when looking at complications, re-interventions, and long-term functional outcomes.

The Effect of Providing Audiovisual Surgical Information on Decisional Conflict in Patients Undergoing Plate Fixation for Distal Radius Fractures

Backgroud

Patients experiencing acute trauma have limited time for their involvement in shared decision making, which may lead to decisional conflict. The purpose of this study was to evaluate whether providing audiovisual surgical information can reduce decisional conflict when deciding between surgical and nonsurgical treatment in patients with distal radius fractures (DRFs) and to evaluate factors that may affect decisional conflict.

Methods

We prospectively enrolled 50 consecutive patients who presented with acute DRFs and chose to undergo surgery, for which volar plate fixation was recommended. We randomized these patients into 2 groups. The test group was given a video clip of audiovisual surgical information in addition to regular information while the control group was only given regular information. The video clip consisted of the purpose, procedure, and effect of the surgery, precautions and complications after the operation, and other treatment options that could be performed if operation was not performed. At 2 weeks after the surgery, we evaluated patients' decisional conflict using a decisional conflict scale (DCS). In addition, we evaluated factors that might affect decisional conflict, such as age, dominant hand, comorbidities, history of previous operations, perceived disability, and provision of the video clip.

Results

The test group showed significantly lower DCS scores than the control group (19.6 vs. 32.1, p = 0.001). In multivariate analysis, younger age and provision of the video clip were associated with lower DCS scores.

Conclusions

This study has demonstrated that providing information through audiovisual media such as video clips could reduce decisional conflict in patients who chose to undergo plate fixation for DRFs. This study also suggests that older patients may need more careful doctor-patient communication as they have more decisional conflict than younger patients.

A Matched Comparison of Postoperative Complications Between Smokers and Nonsmokers Following Open Reduction Internal Fixation of Distal Radius Fractures

PURPOSE

The purpose of the present study was to identify differences in 30-day adverse events, reoperations, readmissions, and mortality for smokers and nonsmokers who undergo operative treatment for a distal radius fracture.

METHODS

The American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database was queried for patients who had operatively treated distal radius fractures between 2005 and 2017. Patient characteristics and surgical variables were assessed. Thirty-day outcome data were collected on serious (SAEs) and minor adverse events (MAEs), as well as on infection, return to the operating room, readmission, and mortality. Multivariable logistic analyses with and without propensity-score matching was used to compare outcome measures between the smoker and the nonsmoker cohorts.

RESULTS

In total, 16,158 cases were identified, of whom 3,062 were smokers. After 1:1 propensity-score matching, the smoking and nonsmoking cohorts had similar demographic characteristics. Based on the multivariable propensity-matched logistic regression, cases in the smoking group had a significantly higher rate of any adverse event (AAE) (odds ratio [OR], 1.75; 95% confidence interval [95% CI], 1.28-2.38), serious adverse event (SAE) (OR, 1.75; 95% CI, 1.22-2.50), and minor adverse event (MAE) (OR, 1.84; 95% CI, 1.04-3.23). Smokers also had higher rates of infection (OR, 1.73; 95% CI, 1.26-2.39), reoperation (OR, 2.07; 95% CI, 1.13-3.78), and readmission (OR, 1.83; 95% CI, 1.20-2.79). There was no difference in 30-day mortality rate.

CONCLUSIONS

Smokers who undergo open reduction internal fixation of distal radius fractures had an increased risk of 30-day perioperative adverse events, even with matching and controlling for demographic characteristics and comorbidity status. This information can be used for patient counseling and may be helpful for treatment/management planning.

Volar locking plate: Age related outcomes and complications

BACKGROUND

There is no unanimity for the treatment of distal radius fractures in older people. The purpose of our study is to assess the efficacy of volar locking plate for the treatment of unstable distal radius fractures in older independent individuals.

METHODS

A retrospective comparative study of 105 patients. 58 patients were below the age of 55 years and 47 above the age of 55 years. Mean follow-up was 18.4 months in patients below the age of 55 years and 18.1 months above the age of 55 years. Wrist movements, complications, reoperations, grip strength, Visual Analogue Score (VAS) for pain, Quick Disabilities of the Arm, Shoulder and Hand (DASH) score, and Mayo wrist score were analysed.

RESULTS

There was no statistical difference in the wrist movements, grip strength, complications, reoperations, VAS, QuickDASH and Mayo scores. Mean grip strength under 55 was 84.1 and above 55 was 84.5 (p = 0.87). The complication rate was 19.1% above 55 years of age and 17.2% below the age of 55years (p = 0.79). The reoperation rate above 55 years was 8.5% and below 55 years was 8.6% (p = 0.50). Mean VAS under 55 years of age was 1.6 and above 55 years was 1.7 (p = 0.58). Mean Mayo score in under 55 was 80.7 and 80.1 in above 55 (p = 0.78). Mean Quick DASH score under 55 was 20.9 and above 55 was 21.0 (p = 0.97).

CONCLUSION

Our results indicate that outcomes in older independent patients are satisfactory with a comparable complication and reoperation rate with younger individuals. We conclude that a volar locking plate is a favourable modality for the treatment of unstable distal radius fractures in older patients.

Epidemiological and Treatment Trends of Distal Radius Fractures across Multiple Age Groups

Background  The purpose of this study is to assess the epidemiology, population-specific treatment trends, and complications of distal radius fractures in the United States. Methods  The PearlDiver database (Humana [2007-2014], Medicare [2005-2014]) was used to access US inpatient and outpatient data for all patients who had undergone operative and nonoperative treatment for a distal radius fracture in the United States. Epidemiologic analysis was performed followed by age-based stratification, to assess prevalence, treatment trends, and rates of complications. Results  A total of 1,124,060 distal radius treatment claims were captured. The incidence of distal radius fractures follows a bimodal distribution with distinct peaks in the pediatric and elderly population. Fractures in the pediatric population occurred predominately in males, whereas fractures in the elderly population occurred more frequently in females. The most commonly used modality of treatment was nonoperative; however, the use of internal fixation increased significantly during the study period, from 8.75 to 20.02%, with a corresponding decrease in percutaneous fixation. The overall complication rate was 8.3%, with mechanical symptoms most frequently reported. Conclusions  The last decade has seen a significant increase in the use of internal fixation as treatment modality for distal radius fractures. The impetus for this change is likely multifactorial and partly related to recent innovations including volar locking plates and an increasingly active elderly population. The implicated financial cost must be weighed against the productivity cost of maintaining independent living to determine the true burden to the healthcare system.

Hardware removal or preservation? Decision making based on a newly developed rating scale

Hardware exposure following open reduction and internal fixation (ORIF) surgery is a tricky problem. It is always hard for surgeons to decide whether to keep or remove the hardware. In this study, a rating scale and corresponding clinical path is developed based on former published paper as well as our own experience. New admitted patients are first evaluated and scored once they enter the department. Based on the score they get, patients are assigned to different therapeutic schedule, i.e. (1) hardware preservation with pedicel flap transplantation, (2) debridement for further reevaluation and (3) hardware removal with external fixation. Satisfying clinical outcome is achieved that is characterized with high osseous consolidation rate and low complication rate. The result showed that this newly developed rating scale and the related therapeutic schedule could be an available tool to help surgeons to make decisions in the treatment of hardware exposure.

Epidemiology and treatment of distal radius fractures: current concept based on fracture severity and not on age

PURPOSE

A shift towards surgical treatment of distal radius fractures seems to be apparent. The purpose of the present study was to assess current epidemiological data, the fracture severity according to the AO classification and the changing trend in the treatment.

METHODS

This study presents a retrospective review of 268 patients ≥ 18 years of age admitted to our level I trauma center with distal radius fractures between 2013 and 2015. The data were obtained from the hospital inpatient enquiry system and review of the radiological examinations.

RESULTS

The ratio between males and females was 87:181. The average age of the patients was 56.9 (18-99) years. A fall from standing position was the most common mechanism of injury. According to the AO classification, 43.3% were type A fractures, 13.1% type B, and 43.7% type C. As the intensity of the injury mechanism increased, the percentage of type C fractures also increased. A total of 61.9% of patients underwent surgery with open reduction and internal fixation with volar locking plates used as the preferred surgical treatment. Fracture severity correlated well with surgical decision. Elderly patients were just as likely to get surgical treatment as adult patients.

CONCLUSIONS

Our findings confirmed the increasing popularity of surgical intervention with open reduction and internal fixation. Contrary to previous studies, the fracture type profile showed an equal proportion of type A and C fractures and the indication for surgical treatment correlated with fracture severity and not age.

Use of a 5-Item Modified Frailty Index for Risk Stratification in Patients Undergoing Surgical Management of Distal Radius Fractures

PURPOSE

Compared with cast treatment, surgery may expose patients with distal radius fractures to undue risk. Surgical intervention in this cohort may offer less benefit than previously thought and appropriate patient selection is imperative. The modified Frailty Index (mFI) predicts complications after other orthopedic surgeries. We hypothesized that this index would predict, and might ultimately prevent, complications in patients older than 50 years with distal radius fractures.

METHODS

We retrospectively reviewed the American College of Surgeons-National Surgery Quality Improvement Program (ACS-NSQIP) database, including patients older than 50 years who underwent open reduction and internal fixation of a distal radius fracture. A 5-item mFI score was then calculated for each patient. Postoperative complications, readmission and reoperation rates, as well as length of stay (LOS) were recorded. Bivariate and multivariable statistical analysis was then performed.

RESULTS

We identified 6,494 patients (mean age, 65 years). Compared with patients with mFI of 0, patients with mFI of 2 or greater were nearly 2.5 times as likely to incur a postoperative complication (1.7% vs 7.4%). Specifically, the rates of Clavien-Dindo IV, wound, cardiac, and renal complications were increased significantly in patients with mFI of 2 or greater. In addition, as mFI increased from 0 to 2 or greater, 30-day reoperation rate increased from 0.8% to 2.4%, 30-day readmission from 0.8% to 4.6%, and LOS from 0.5 days to 1.44 days. Frailty was associated with increased complications as well as rates of readmission and reoperation even when controlling for demographic data, LOS, and operative time. Age alone was not significantly associated with postoperative complications, readmission, reoperation, or LOS.

CONCLUSIONS

A state of frailty is highly predictive of postoperative complications, readmission, reoperation, and increased LOS following open reduction and internal fixation of distal radius fractures. Our data suggest that a simple frailty evaluation can help inform surgical decision making in patients older than 50 years with distal radius fractures.

Cost minimization analysis of the treatment of distal radial fractures in the elderly

AIMS

The aim of this study was to test the null hypothesis that there is no difference, from the payer perspective, in the cost of treatment of a distal radial fracture in an elderly patient, aged > 65 years, between open reduction and internal fixation (ORIF) and closed reduction (CR).

MATERIALS AND METHODS

Data relating to the treatment of these injuries in the elderly between January 2007 and December 2015 were extracted using the Humana and Medicare Advantage Databases. The primary outcome of interest was the cost associated with treatment. Secondary analysis included the cost of common complications. Statistical analysis was performed using a non-parametric t-test and chi-squared test.

RESULTS

Our search yielded 8924 patients treated with ORIF and 5629 patients treated with CR. The mean cost of an uncomplicated ORIF was more than a CR ($7749 versus $2161). The mean additional cost of a complication in the ORIF group was greater than in the CR group ($1853 versus $1362).

CONCLUSION

These findings show that there are greater payer fees associated with ORIF than CR in patients aged > 65 years with a distal radial fracture. CR may be a higher-value intervention in these patients. Cite this article: Bone Joint J 2018;100-B:205-11.

Is a short arm cast appropriate for stable distal radius fractures in patients older than 55 years? A randomized prospective multicentre study

We conducted a prospective randomized, multicentre study to compare short arm and long arm plaster casts for the treatment of stable distal radius fracture in patients older than 55 years. We randomly assigned patients over the age of 55 years who had stable distal radius fracture to either a short arm or long arm plaster cast at the first review 1 week after their injury. Radiographic and clinical follow-up was conducted at 1, 3, 5, 12 and 24 weeks following their injury. Also, degree of disability caused by each cast immobilization was evaluated at the patient's visit to remove the cast. There were no significant differences in radiological parameters between the groups except for volar tilt. Despite these differences in volar tilt, neither functional status as measured by the Disabilities of the Arm, Shoulder and Hand, nor visual analogue scale was significantly different between the groups. However, the mean score of disability caused by plaster cast immobilization and the incidence rate of shoulder pain were significantly higher in patients who had a long plaster cast. Our findings suggest that a short arm cast is as effective as a long arm cast for stable distal radius fractures in the elderly. Furthermore, it is more comfortable and introduces less restriction on daily activities.

A comparative study of functional outcome of treatment of intra articular fractures of distal radius fixed with percutaneous Kirschner's wires vs T-plate

BACKGROUND & OBJECTIVE

Fractures of the distal radius are common with a variable prognosis in case of intra articular extension. The available options include Plaster, External fixation, Prefabricated Splintage using Ligamentotaxis, K-wire fixation, and open reduction internal fixation with T-plate without an as yet clear advantage of one over the others. If these fractures are allowed to collapse, radial shortening, angulation and articular incongruity may cause permanent deformity and loss of function. This limited small scale study was intended to compare the functional results of treatment of these fractures with a T plate and K-wires.

METHODS

This was a prospective experimental study conducted at department of Orthopedics of PGMI/Lahore General Hospital, Lahore. Total 30 patients were included and randomized into two groups of 15 patients each. Group-A patients were treated with Krischner's wires and Group-B patients were treated with a T-Plate with open reduction. Informed consent was taken. Post operative follow up was done for 12 weeks for the outcome parameters (Green and O'Brien score).

RESULTS

Mean age of patients in Group-A and B was 36.13±9.81 and 44.73±7.86 years respectively. In Group-A there were 10 male and 5 female patients and in Group-B there were 8 male and seven female patients respectively. In Group-A nine patients presented with Fernandez type-II and six patients presented with Fernandez type-III fracture. While in Group-B 10 patients presented with Fernandez type-II and five patients presented with Fernandez type-III fracture. Among Group-A patient's final outcome was excellent in 86.67% patients while in Group-B only 53.33% patients had excellent outcome at three months follow up.

CONCLUSION

Percutaneous Kirschner's wires appeared to be more effective as compared to T-Plate fixation in terms of functional outcome for treating intra-articular distal radius fractures.

Determinants of Functional Outcome in Distal Radius Fractures in High-Functioning Patients Older Than 55 Years

OBJECTIVES

To determine the influence of treatment and radiographic parameters on patient-reported functional outcomes on a population of non-frail elderly with distal radius fractures.

DESIGN

Prospective cohort study.

SETTING

Level 1 trauma center.

PATIENTS/PARTICIPANTS

Patients older than 55 years presenting with a distal radius fracture and a Canadian Study of Health and Aging Clinical Frailty Scale score of 1 or 2.

INTERVENTION

Closed reduction and casting or open reduction and internal fixation as per the treating surgeons' decision.

MAIN OUTCOME MEASURES

Radiographic scores at baseline, 6 weeks, and 12 weeks, as well as Disabilities of the Arm, Shoulder and Hand, Short Form 36, and Patient-Reported Wrist Evaluation scores up to 1 year after injury. Univariate analysis and linear regression analysis were performed on outcome measures.

RESULTS

No difference exists in outcomes based on treatment choice. Patients with ulnar positivity greater than 2 mm at baseline, after treatment, and at final follow-up had worse patient-reported scores at 1 year. Persistent articular gaps and/or steps greater than 2 mm after treatment were also associated with worse patient-reported outcomes.

CONCLUSION

Even in high-functioning patients older than 55 years, there was no difference in patient-reported outcomes at 1 year in the open reduction group as compared with the closed reduction group. Instead, physicians should pay particular attention to radial shortening and persistent articular gaps following their chosen treatment plan for distal radial fractures.

Safety and Efficacy of Operative Versus Nonsurgical Management of Distal Radius Fractures in Elderly Patients: A Systematic Review and Meta-analysis

PURPOSE

To assess the safety and efficacy of operative versus nonsurgical treatment of distal radius fractures in elderly patients.

METHODS

We comprehensively searched the PubMed, Web of Science, and Cochrane Library databases for studies that satisfied predetermined inclusion and exclusion criteria. Outcomes of interest included pain level, grip strength, wrist range of motion, wrist functional assessment, radiographic parameters, and complications; we compared these using continuous measurements. We performed a systematic review and meta-analysis to assess operative versus nonsurgical procedures in patients aged 60 years and older.

RESULTS

Two randomized controlled trials and 6 retrospective studies were included. Meta-analysis did not detect statistically significant differences in pooled data for pain level, functional assessment, and wrist range of motion between the operative and nonsurgical groups. Grip strength was significantly greater in the operative group. The incidence of major complications requiring surgery and that of tendon injury were significantly higher in the operative group. Radiographic outcomes including volar tilt, radial inclination, and ulnar variance were significantly better in the operative group. Considerable heterogeneity was present in all studies and adversely affected the precision of the meta-analysis.

CONCLUSIONS

The current literature does not support the theory that operative management can provide better clinical outcomes for elderly patients with distal radius fractures. Although operative management can offer better radiographic outcomes and grip strength than can nonsurgical treatment, the risk of complications requiring surgical treatment is greater. Thus, indications for operative fixation should be considered carefully in the treatment of elderly patients.

Multiple ruptures of the extensor tendons after volar fixation for distal radius fracture: a case report

A 62-year-old woman was admitted to our hospital after a bicycle accident with a displaced left (non-dominant) distal radius fracture. After closed reduction a long cast was applied. Due to loss of reduction, twenty-four days later open reduction internal fixation with locking compression plate (LCP) was performed. The patient returned to her normal activities but nineteen months after surgery showed functional impairment of the left thumb for Extensor Pollicis Longus (EPL) injury for which she necessitated transposition surgery. Twenty-six months after ORIF, functional deficit of the extension of the third and fourth left finger was noted secondary to injury of extensor tendons. Ultrasound and CT scan showed protrusion of the angular stability screws in LCP plate that caused a progressive wear resulting in rupture of the extensor tendons. Another tendon transposition surgery was performed with dorsal approach while the plate was removed utilising the original volar incision. Reconstruction of distal radius fractures with volar plating, requires accurate plate application with precise measurement of the length of the screws in order to prevent dorsal protrusion and thus avoiding tendon injuries.

Displaced Intra-Articular Fractures of the Distal Radius: Open Reduction With Internal Fixation Versus Bridging External Fixation

Background:

Distal radius fracture is common in all ages. Mobility and wrist function is important. The choice of treatment should aim for optimal function with minimal complications.

Objectives:

In this study we compared two surgical approaches, open reduction and internal fixation (ORIF) and closed reduction with external fixation (CR + EF), for treatment of intra-articular distal radius fractures.

Patients and Methods:

Ninety-four patients with distal radius fracture (type 3, 4 and 5 Fernandez classification) were treated with two surgical methods (ORIF and CR + EF); 55 were treated with CR + EF and 39 were treated with ORIF by different surgeons. All patients were assessed at the end of the first, third and sixth week; and then after the third, sixth and 12^th month. At the end of the follow-up, all patients completed the Michigan hand outcome questionnaire (MHOQ). We compared radiological parameters of distal radius, range of motion (ROM) of the wrist, duration of rehabilitation, complication and patient satisfaction of the methods.

Results:

In our study, radiological findings for the ORIF group were radial inclination (RI): 19.35, radial length (RL): 10.35, radial tilt (RT): 8.92, and ulnar variance (UV): 1.64, while for the CR + EF group these were RI: 15.13, RL: 8, RT: 4.78, and UV: 0.27. The ROM for ORIF were flexion/extension (F/E): 137, Radial/Ulnar deviation (R/U): 52, and Supination/Pronation (S/P): 141, while for the CR + EF group these were F/E: 117, R/U: 40 and S/P: 116. Michigan hand outcome score for ORIF was 75% and for Ext. fix was 60%. The rate of complication with the ORIF method was 58% and in Ext. fix this was 69%. The patients in CR + EF had more than the ORIF course of physiotherapy and rehabilitation.

Conclusions:

In comparison of ORIF and CR + EF, all results including functional score, clinical and radiologic criteria were in favor of the ORIF method while there were less complications with this method. We believe that ORIF is a better method for treatment of these types of fractures.

Avoiding Heparinization of Arterial Line and Maintaining Acceptable Arterial Waveform After Cardiac Surgery: A Randomized Clinical Trial

Background:

Invasive and continuous blood pressure (BP) monitoring is crucial after cardiac surgery. Accuracy of BP measurement mostly depends on patency of arterial catheter and acceptable waveform. Heparinized saline flush usually used for this purpose may be accompanied by potential heparin adverse effects.

Objectives:

The aim of this study was to compare heparinized and non-heparinized saline flush to maintain acceptable arterial waveform after cardiac surgery.

Materials and Methods:

In a double blind randomized trial study, 100 patients undergoing elective cardiac surgery were randomized to using heparinized (n = 50) or non-heparinized (normal) saline flush (n = 50) to maintain patency of arterial catheter after operation. Indwelling arterial catheters were checked daily for acceptable arterial waveform for three days as primary outcome measures.

Results:

Frequency of acceptable arterial waveform ranged from 66% to 80%, in first, second and third postoperative days. There were no statistically significant differences between heparinized and non-heparinized saline groups regarding acceptable arterial waveforms in all the three postoperative days (all P values > 0.05).

Conclusions:

Using non-heparinized normal saline is suitable to maintain acceptable arterial waveform for short-term (three days) after adult cardiac surgery considering potential adverse effects of heparin.

Risk factors for complications following open reduction internal fixation of distal radius fractures

PURPOSE

A national surgical database was used to determine risk factors for complications in patients undergoing open reduction internal fixation (ORIF) for distal radius fractures.

METHODS

The American College of Surgeons National Surgical Quality Improvement Program database for the 2006-2012 years was queried to identify all patients who underwent an ORIF of a distal radius fracture based on Current Procedural Terminology codes 25607, 25608, or 25609. The database is a statistically representative sample of prospectively collected perioperative surgical data from hospitals primarily in the United States. Demographics, comorbidities, preoperative laboratory values, and 30-day complications were compared between the patient groups with and without a postoperative complication. Multivariate analysis was performed to identify patient characteristics and comorbidities that were independently associated with early postoperative complications.

RESULTS

This retrospective analysis identified 3,003 patients who underwent an ORIF of the distal radius over 7 years. The number of patients with a complication within 30 days after surgery was 62 (2%), totaling 90 complications. Incidence of return to the operative room for the entire study population was 1.1%. Multivariate analysis, adjusting for confounding variables, showed that patients with a complication were more likely to have hypertension, congestive heart failure, preoperative chemotherapy or radiotherapy, longer operating time, and manifest preoperative impairment in independent living.

CONCLUSIONS

Approximately 2% of patients sustained a complication within 30 days following ORIF of a distal radius fracture. Recognition of the risk factors may help avoid complications in the identified high-risk patients.

External fixation versus open reduction with locked volar plating for geriatric distal radius fractures

The optimal management of displaced dorsal radius fractures (DRFs) in older patients remains an issue of debate. Bridging external fixation is a well-accepted treatment modality for severely comminuted DRFs, while open reduction and internal fixation with locked volar plating has emerged as a promising alternative in recent years. The current body of randomized trials supports the trend toward locked volar plating, as it allows for quicker improvement in subjective and functional outcomes. There is no clear evidence to suggest that one technique carries significantly less complications than the other. Locked volar plating should be considered in patients for whom an accelerated functional recovery would be advantageous. Otherwise, both external fixation and locked volar plating provide good long-term clinical outcomes.

Accelerated rehabilitation compared with a standard protocol after distal radial fractures treated with volar open reduction and internal fixation: a prospective, randomized, controlled study

BACKGROUND

There are relatively few studies in the literature that specifically evaluate accelerated rehabilitation protocols for distal radial fractures treated with open reduction and internal fixation (ORIF). The purpose of this study was to compare the early postoperative outcomes (at zero to twelve weeks postoperatively) of patients enrolled in an accelerated rehabilitation protocol with those of patients enrolled in a standard rehabilitation protocol following ORIF for a distal radial fracture. We hypothesized that patients with accelerated rehabilitation after volar ORIF for a distal radial fracture would have an earlier return to function compared with patients who followed a standard protocol.

METHODS

From November 2007 to November 2010, eighty-one patients with an unstable distal radial fracture were prospectively randomized to follow either an accelerated or a standard rehabilitation protocol after undergoing ORIF with a volar plate for a distal radial fracture. Both groups began with gentle active range of motion at three to five days postoperatively. At two weeks, the accelerated group initiated wrist/forearm passive range of motion and strengthening exercises, whereas the standard group initiated passive range of motion and strengthening at six weeks postoperatively. Patients were assessed at three to five days, two weeks, three weeks, four weeks, six weeks, eight weeks, twelve weeks, and six months postoperatively. Outcomes included Disabilities of the Arm, Shoulder and Hand (DASH) scores (primary outcome) and measurements of wrist flexion/extension, supination, pronation, grip strength, and palmar pinch.

RESULTS

The patients in the accelerated group had better mobility, strength, and DASH scores at the early postoperative time points (zero to eight weeks postoperatively) compared with the patients in the standard rehabilitation group. The difference between the groups was both clinically relevant and statistically significant.

CONCLUSIONS

Patients who follow an accelerated rehabilitation protocol that emphasizes motion immediately postoperatively and initiates strengthening at two weeks after volar ORIF of a distal radial fracture have an earlier return to function than patients who follow a more standard rehabilitation protocol.

Outcomes and cost of care for patients with distal radius fractures

This study was designed to evaluate treatment patterns in open treatment and percutaneous fixation of distal radius fractures, compare morbidity rates for the 2 types of treatment, and compare costs associated with the procedure and treatment of complications up to 1 year after surgery. From a 5% sample of nationwide Medicare claims records (1997-2009), patients with distal radius fractures were identified with International Classification of Diseases, 9th revision, Clinical Modification (ICD-9-CM), codes. Patients who underwent percutaneous fixation and open treatment were tracked with appropriate Current Procedural Terminology codes. Complications were identified at 3 and 12 months. Medicare charges and payments associated with the treatment groups were compiled from the claims data. The rate of surgical treatment increased from 44.7 to 82.0 surgeries per 100,000 persons (+83.0%) over the study period. A total of 9343 procedures met the inclusion criteria between 1998 and 2008. The proportion of open treatment procedures increased from 25.5% in 1998 to 73.4% in 2008. Percutaneous fixation was associated with lower adjusted risk of carpal tunnel syndrome and release and mononeuritis at 3 and 12 months. The percutaneous fixation group had lower adjusted risk of malunion/nonunion at 3 months and tendon rupture at 12 months. Average charges were lower in the percutaneous fixation group for the index operation as well as for treatment of morbidities at 3 and 12 months. The operative fixation rate for distal radius fractures in the Medicare population continues to rise, with a significant trend toward open fixation. Charges and payments associated with open treatment are significantly higher than those for percutaneous fixation.

Fixation of distal ulna fractures associated with distal radius fractures using intrafocal pin plate

Background Unstable distal ulna fractures in the setting of distal radius fractures can present a challenging problem, especially in the elderly population. Operative fixation of the subcapital distal ulna fracture may help to provide a stable ulnar buttress for attempting to reduce the distal radius fracture. Traditional fixation techniques of the distal ulna may prove unsatisfactory in the setting of osteoporosis and comminution. Description The intrafocal pin plate is placed through a small incision distally and uses the curve of the plate to obtain multiple points of fixation within the intramedullary canal. The overhang of the distal aspect of the plate helps to reduce the fracture. The plate is secured using unicortical locking screws in the ulnar head. Patients and Methods The most ideal fracture pattern for this fixation technique is a subcapital distal ulna fracture that is unstable and associated with a distal radius fracture. This technique is contraindicated in ulnar head fractures, segmental fractures with proximal extension, and open fractures with gross contamination as well as in the setting of active infection. Results This technique has provided a stable ulnar buttress and aided in the reduction of grossly unstable distal radius fractures. All of these patients have gone on to union, and we have not experienced a need for plate removal due to pain or soft tissue irritation. Conclusions We have found the intrafocal pin plate to provide both a stable ulnar buttress as well as intramedullary fixation to aid in the fixation of distal radius fractures associated with unstable distal ulna subcapital fractures.

A simple method for choosing treatment of distal radius fractures

PURPOSE

To design an easy-to-use guide for decision making in distal radius fractures in patients older than 50 years and to retrospectively analyze its ability to predict treatment in 164 patients.

METHODS

The present study consisted of 4 parts. The first part was a review of the literature to identify possible important factors that predict treatment outcome of distal radius fractures in patients 50 years old and older. The second part identified which of these first-tier factors that orthopedic surgeons consider to be important by a questionnaire that was sent to 83 orthopedic surgeons qualified by the Japanese Orthopedic Association with response rate of 61%. The third part further identified which of the subsets of factors best predict outcome in a retrospective study of 41 patients 50 years old or older, yielding a final subset of factors to create a scoring system. The fourth part of the study then evaluated the ability of this scoring system to predict the outcome as evaluated by the modified Mayo wrist score and the Disabilities of the Arm, Shoulder and Hand score in a retrospective study of 164 distal radius fractures in patients 50 years old or older.

RESULTS

The 164 patients were divided into 4 groups by the present scoring system: conservative group, relative conservative group, relative surgical group, and surgical group according to the recommended therapeutic modalities. Clinical outcomes of those that followed the recommendation of the present scoring system resulted in favorable consequences. In contrast, the outcomes of those not following the recommendation were inferior.

CONCLUSIONS

The present scoring system may be used as an easy-to-use decision-making tool when choosing conservative or surgical treatment for distal radius fractures.

Patterns of CT use and surgical intervention in upper limb periarticular fractures at a level-1 trauma centre

OBJECTIVES

The universal availability of CT scanners has led to lower thresholds for imaging despite significant financial costs and radiation exposure. We hypothesised that this recent trend has increased the use of CT for upper limb periarticular fractures and led to more frequent operative management.

METHOD

A 5-year retrospective study (01/07/2005-30/06/2010) was performed on all adult patients with upper extremity periarticular fractures (OTA: 11, 13, 21 and 23) admitted to a level-1 trauma centre. Patients were identified from the institution's prospectively maintained OTA classification database.

RESULTS

A total of 1734 upper extremity periarticular fractures were identified in 1651 patients. 65% (1132/1734) were operated on. 32% (557/1734) had CT imaging and 78% (431/557) of these had operative management. CT use for all fractures and ages showed no change (0.56%/year, p = 0.210, r(2) = 0.457). Operative intervention increased at a rate of 2.17%/year (p = 0.004, r(2) = 0.959). Within each fracture type, CT rates showed no change. Operative management of proximal humerus and distal radius fractures became more frequent (6.30%/year, p = 0.002, r(2) = 0.969 and 0.96%/year, p = 0.046, r(2) = 0.784 respectively). Fractures around the elbow showed no change. In patients younger than 55 years, only proximal humerus fractures had more frequent imaging (3.17%/year, p = 0.023, r(2) = 0.866). In patients over 55 the frequency of CT scanning did not increase, but they were more frequently operated on (4.09%/year, p = 0.012, r(2) = 0.907). In older patients the rate of surgical intervention increased in all but the distal humerus region, Proximal humerus (6.19%/year, p = 0.015, r(2) = 0.894), proximal forearm (4.57%/year, p = 0.007, r(2) = 0.931) and distal radius (2.70%/year, p = 0.002, r(2) = 0.871).

CONCLUSION

During the examined 5-year period no increases of in CT imaging frequency were observed. The significantly increased number of operations among older patients is unlikely to be driven by imaging frequency.

Evaluation and treatment of osetoporotic distal radius fracture in the elderly patient

Distal radius fractures are an increasingly prevalent upper extremity injury, especially among elderly patients. While treatment guidelines for the acute bony injury have been well documented, treatment of the underlying metabolic bone disease has been less commonly discussed in the orthopedic literature. Distal radius fractures in the elderly patient should be considered a sentinel event for injuries associated with greater morbidity and mortality, such as hip fracture. Management of fracture-related factors, such as osteoporosis and increased fall risk following a distal radius fracture, may prevent the mortality and morbidity of future injuries. This review highlights both the fracture-specific and medical goals of treatment in the elderly patient with a distal radius fracture.

Treatment of unstable distal ulna fractures associated with distal radius fractures in patients 65 years and older

PURPOSE

To prospectively compare the clinical and radiological outcomes of 2 treatment methods for unstable distal ulna fractures associated with distal radius fractures in patients 65 years of age and older.

METHODS

From February 2008 to March 2010, the first 29 ulnas were treated surgically (group 1) and the next 32 ulnas were treated nonoperatively (group 2). The mean final follow-up period was 34 months (range, 24-56 mo). All radiuses were fixed internally, in both groups. Clinical outcomes were compared between groups using a visual analog scale for postoperative pain; Disabilities of the Arm, Shoulder, and Hand scores; active range of motion; grip strength; and the modified system of Gartland and Werley. Radiological outcomes, including ulnar variance, were evaluated. Arthrosis was evaluated at the radiocarpal joint or distal radioulnar joint (DRUJ) according to the system of Knirk and Jupiter.

RESULTS

There were no significant differences between the groups in any of the clinical outcomes. No significant differences were observed for radiological outcomes including ulnar variance, distal radius, and union rate. There were no patients in either group with symptomatic arthritic changes in the radiocarpal joint or DRUJ at the final follow-up. In group 2, 1 patient had malunion (angulated, 14°) on the anteroposterior view without evidence of arthrosis in the DRUJ, and functional outcomes were good.

CONCLUSIONS

In this population distal ulna fractures can be successfully managed nonoperatively when they occur in combination with distal radius fractures.

Locking versus nonlocking palmar plate fixation of distal radius fractures

This study compared functional and radiological outcomes after treatment of extension-type distal radius fractures with conventional titanium nonlocking T-plates or titanium 1.5-mm locking plates. A total of 60 patients were included and followed for 4 to 7 years after receiving nonlocking T-plates (group A; n=30) or locking plates (group B; n=30) with and without dorsal bone grafting. Bone grafting was significantly more often performed in the nonlocking group to increase dorsal fracture fixation and stability (P<.003). Pre- and postoperative and follow-up values for palmar tilt, radial inclination, radial shortening, and ulnar variance were recorded. Age, sex, and fracture type were similarly distributed between the 2 groups. Postoperative and follow-up evaluation revealed equal allocation of intra-articular step formation and osteoarthritic changes to both groups. The overall complication rate was 25%. Compared with the nonlocking system, patients undergoing locking plate fixation presented with statistically significantly better values for postoperative palmar tilt (5.53° vs 8.15°; P<.02) and radial inclination (22.13° vs 25.03°; P<.02). However, forearm pronation was significantly better in group A (P<.005). At follow-up, radial inclination tended to approach a statistically significant difference in favor of group B. All clinical assessment, including Mayo wrist score, Disabilities of the Arm, Shoulder, and Hand score, Green and O'Brien score, Gartland and Werley score, visual analog scale score, and grip strength, yielded no statistically significant difference between the 2 groups. Locking plates seem to provide benefits regarding surgical technique and comfort, improvement in implant anchorage (especially in osteoporotic bone), and reduce the necessity of additional bone grafting.

[Volar locking plating for distal radial fractures. Is osteoporosis associated with poorer functional results and higher complications rates?]

BACKGROUND

The purpose of this prospective study was to compare the functional and radiological results and complication rates after locking plate osteosynthesis of unstable distal radial fractures in elderly patients as a function of the bone mineral density (BMD). The hypothesis that reduced BMD is accompanied by poorer function and a higher rate of complications was investigated.

PATIENTS AND METHODS

A total of 65 consecutive patients with unstable distal radial fractures, AO 23-A2 (n=1), -A3 (n=29), -C1 (n=2), -C2 (n=28) and -C3 (n=5) were included with a mean age of 69 years (range, 52-86 years). Standardized clinical and radiological follow-up was performed 6 weeks, 3 and 12 months postoperatively. All patients underwent dual x-ray absorptiometry of the contralateral distal radius within 6 weeks postoperatively and 3 groups could be differentiated: group I (n=27) osteoporosis, group II (n=27) osteopenia and group III (n=11) normal BMD. Data on the DASH and QAL scores as well as the range of motion, grip strength and radiological parameters were collected. According to the BMD a detailed analysis of complications was performed.

RESULTS

Exemplary the 12 months results of DASH and the range of motion are shown here: the DASH 12 months postoperatively was DASH(total)=6 (0-64) P, DASH(group I)=7 (0-32.5) P, DASH(group II)=11 (1-63) P, DASH(group III)=2 (0-23) P, no significance. The range of motion increased significantly in all 3 groups (except pronation in groups I and III) from 6 weeks to 3 and 12 months postoperatively and 12 months postoperatively showed means for dorsal extension 55° (25-75), palmar flexion 55° (35-75), ulnar abduction 35° (20-45), radial abduction 20° (5-40), supination 90° (60-90) and pronation 85° (65-90) in the total sample. The comparison of DASH and range of motion was not significantly different at each time of follow-up between all 3 groups. A group-specific analysis of implant and BMD dependent complications showed 2/27 (7%) secondary intra-articular screw perforations in group I, 1/27 (4%) in group II and 0/11 in group III.

CONCLUSION

The hypothesis that a reduced BMD is accompanied by a poorer function and a higher rate of complications was refuted. Analysis of complications showed a trend to more BMD-dependent complications in the osteoporosis group.

Common myths and evidence in the management of distal radius fractures

Distal radius fractures (DRFs) are the most common fracture treated by physicians, but questions remain regarding optimal management. Fracture patterns, biomechanics, and treatment strategies have been debated for more than 200 years, and research shows many controversies regarding long-held beliefs. Although these common myths have been propagated and considered fact, they are not based on the best-available evidence. This article illustrates some of the major controversies regarding the management of DRFs. To provide optimal care in a world of evidence-based medicine, clinicians must shift their thinking and accept that some of the indoctrinated ideas may represent a flawed heuristic approach.

Comparative analysis of intramedullary nail fixation versus casting for treatment of distal radius fractures

PURPOSE

Intramedullary fixation is one treatment option for distal radius fractures. Our purpose was to compare the outcomes of intramedullary nailing to those of casting for these injuries.

METHODS

From 2006 to 2009, we reviewed 63 adult patients with isolated distal radius fractures. Thirty-one patients had surgical fixation with an intramedullary device (IMN group) within 4 weeks of the injury, and 32 (cast group) had casting as definitive treatment of the fracture. Clinical outcomes (grip strength; Disabilities of the Arm, Shoulder, and Hand scores; active wrist range of motion; and complications) and radiographic indices (radial inclination, radial height, ulnar variance, and tilt) of both groups were analyzed for the 1-, 2-, 4-, 6-, and 12-month follow-up periods.

RESULTS

The flexion-extension arc was significantly higher in the IMN group than in the cast group at 2-, 6-, and 12-month follow-up. The IMN group exhibited significantly greater grip strength and lower DASH scores throughout the follow-up period. At final follow-up, all radiographic indices were significantly better in the IMN group than in the cast group. There was no significant difference between the initial reduction to final position in the IMN group, but the cast group showed an increase in ulnar variance and a significant change in dorsal-volar tilt. In addition, the cast group experienced more clinical complications in the delayed period compared to the IMN group.

CONCLUSIONS

Intramedullary nail fixation, as compared to casting, results in less functional disability, not only in the early postoperative period but also up to a year after treatment. On the basis of our data, intramedullary fixation should be considered for patients with unstable extra-articular or simple intra-articular distal radius fractures.

A prospective randomized trial comparing nonoperative treatment with volar locking plate fixation for displaced and unstable distal radial fractures in patients sixty-five years of age and older

BACKGROUND

Despite the recent trend toward the internal fixation of distal radial fractures in older patients, the currently available literature lacks adequate randomized trials examining whether open reduction and internal fixation (ORIF) with a volar locking plate is superior to nonoperative (cast) treatment. The purpose of the present randomized clinical trial was to compare the outcomes of two methods that were used for the treatment of displaced and unstable distal radial fractures in patients sixty-five years of age or older: (1) ORIF with use of a volar locking plate and (2) closed reduction and plaster immobilization (casting).

METHODS

A prospective randomized study was performed. Seventy-three patients with a displaced and unstable distal radial fracture were randomized to ORIF with a volar locking plate (n = 36) or closed reduction and cast immobilization (n = 37). The outcome was measured on the basis of the Patient-Rated Wrist Evaluation (PRWE) score; the Disabilities of the Arm, Shoulder and Hand (DASH) score; the pain level; the range of wrist motion; the rate of complications; and radiographic measurements including dorsal radial tilt, radial inclination, and ulnar variance.

RESULTS

There were no significant differences between the groups in terms of the range of motion or the level of pain during the entire follow-up period (p > 0.05). Patients in the operative treatment group had lower DASH and PRWE scores, indicating better wrist function, in the early postoperative time period (p < 0.05), but there were no significant differences between the groups at six and twelve months. Grip strength was significantly better at all times in the operative treatment group (p < 0.05). Dorsal radial tilt, radial inclination, and radial shortening were significantly better in the operative treatment group than in the nonoperative treatment group at the time of the latest follow-up (p < 0.05). The number of complications was significantly higher in the operative treatment group (thirteen compared with five, p < 0.05).

CONCLUSIONS

At the twelve-month follow-up examination, the range of motion, the level of pain, and the PRWE and DASH scores were not different between the operative and nonoperative treatment groups. Patients in the operative treatment group had better grip strength through the entire time period. Achieving anatomical reconstruction did not convey any improvement in terms of the range of motion or the ability to perform daily living activities in our cohorts.

An economic analysis of outcomes and complications of treating distal radius fractures in the elderly

PURPOSE

There is a lack of scientific data regarding which treatment provides the best outcome for distal radius fractures (DRFs) in the elderly. Currently, casting is used to treat the majority of these fractures, although open reduction and internal fixation (ORIF) has been used increasingly in recent years. Given the recent emphasis on the wise use of medical resources, we conducted a cost-utility analysis to assess which of 4 common DRF treatments (casting, wire fixation, external fixation, or ORIF) optimizes the cost-to-patient preference ratio.

METHODS

We created a decision tree to model the process of choosing a DRF treatment and experiencing a final outcome. Fifty adults aged 65 and older were surveyed in a time trade-off, one-on-one interview to obtain utilities for DRF treatments and possible complications. We gathered Medicare reimbursement rates and calculated the incremental cost-utility ratio for each treatment.

RESULTS

Participants rated DRF treatment relatively high, assigning utility values close to perfect health to all treatments. The ORIF was the most preferred treatment (utility, 0.96), followed by casting (utility, 0.94), wire fixation (utility, 0.94), and external fixation (utility, 0.93). The ORIF was the most expensive treatment (reimbursement, $3,516), whereas casting was the least expensive (reimbursement, $564). The incremental cost-utility ratio for ORIF, when compared to casting, was $15,330 per quality-adjusted life years, which is less than $50,000 per quality-adjusted life year, thereby indicating that, from the societal perspective, ORIF is considered a worthwhile alternative to casting.

CONCLUSIONS

There is a slight preference for the faster return to minimally restricted activity provided by ORIF. Overall, patients show little preference for one DRF treatment over another. Because Medicare patients pay similar out-of-pocket costs regardless of procedure, they are not particularly concerned with procedure costs. Considering the similar long-term outcomes, this study adds to the uncertainty surrounding the choice of DRF treatment in the elderly, further indicating the need for a high-powered, randomized trial.

ARTHROSCOPICALLY ASSISTED REDUCTION WITH VOLAR PLATING OR EXTERNAL FIXATION FOR DISPLACED INTRA-ARTICULAR FRACTURES OF THE DISTAL RADIUS IN THE ELDERLY PATIENTS

Twenty-eight patients older than 70 years with AO type C fracture of the distal radius were treated with arthroscopically assisted reduction combined with volar plating or external fixation. The patients were followed up for an average of 24.9 ± 16.1 months. The average score was 80.1 ± 10.5 according to the modified system of Green and O'Brien. Eight patients had an excellent result, 11 had a good result, seven had a fair result, and two had a poor result. Twenty-three patients were able to return to their previous activities level or occupation without any restriction. On the basis of these results, we concluded that arthroscopically assisted reduction combined with volar plating or external fixation is one of the useful options for the treatment of a displaced intra-articular fracture of the distal radius in elderly patients who are physiologically young or active.

A systematic review of outcomes and complications of treating unstable distal radius fractures in the elderly

PURPOSE

As the population in developed countries continues to age, the incidence of osteoporotic distal radius fractures (DRFs) will increase as well. Treatment of DRF in the elderly population is controversial. We systematically reviewed the existing literature for the management of DRFs in patients aged 60 and over with 5 common techniques: the volar locking plate system, nonbridging external fixation, bridging external fixation, percutaneous Kirschner wire fixation, and cast immobilization (CI).

METHODS

We reviewed articles retrieved from MEDLINE, Embase, and CINAHL Plus that met predetermined inclusion and exclusion criteria in 2 literature reviews. Outcomes of interest included wrist arc of motion, grip strength, functional outcome measurements, radiographic parameters, and the number and type of complications. We statistically analyzed the data using weighted means and proportions based on the sample size in each study.

RESULTS

We identified 2,039 papers and selected 21 papers fitting the inclusion criteria in the primary review of articles with a mean patient age of 60 and older. Statistically significant differences were detected for wrist arc of motion, grip strength, and Disabilities of the Arm, Shoulder, and Hand score, although these findings may not be clinically meaningful. Volar tilt and ulnar variance revealed significant differences among groups, with CI resulting in the worst radiographic outcomes. The complications were significantly different, with CI having the lowest rate of complications, whereas the volar locking plate system had significantly more major complications requiring additional surgical intervention.

CONCLUSIONS

This systematic review suggests that despite worse radiographic outcomes associated with CI, functional outcomes were no different from those of surgically treated groups for patients age 60 and over. Prospective comparative outcomes studies are necessary to evaluate the rate of functional recovery, cost, and outcomes associated with these 5 treatment methods.

Stabilization and treatment of Colles' fractures in elderly patients

Colles’ fractures (fractures of the distal radius) are extremely common in the elderly. These fractures tend to result in displacement in elderly people because they have osteoporotic bone. Fracture displacement in the elderly, however, does not necessarily result in functional impairment. This review looks at the current literature on distal radius fractures in the elderly and the treatment options for stabilization of these fractures. These include conservative management with cast immobilization or surgical options: internal fixation, external fixation, percutaneous pinning, and bone substitutes.

DISTAL RADIAL FRACTURES IN PATIENTS OVER 60 YEARS OLD: ORTHOGONAL PLATES VERSUS VOLAR PLATE

Objective: To compare the results from surgical treatment between volar plates with angular stability and orthogonal plates in unstable distal radius fractures, in patients aged over 60 years. Methods: The patients were divided into two groups that were treated with volar plates or orthogonal plates. Clinical and radiographic results were analyzed prospectively. Results: The study groups presented similar clinical and radiographic results six months after the operation. However, three months after the surgery, the volar plate group had superior results. Conclusion: Both group presented good functional results. Surgical treatment enabled early rehabilitation. The orthogonal plate technique required a longer learning curve, presented more complications and worse initial results.

Nonbridging external fixation of distal radius fractures

Surgical management of distal radius fractures continues to evolve because of their high incidence in an increasingly active elderly population. Traditional radiocarpal external fixation relies on ligamentotaxis for fracture reduction but has several drawbacks. Nonbridging external fixation has evolved to provide early wrist mobility in the setting of anatomic fracture reduction. Several studies of the nonbridging technique have demonstrated satisfactory results in isolated nonbridging external fixation series and in comparison with traditional spanning external fixation. Nonbridging external fixation for surgical treatment of distal radius fractures can be technically demanding and requires at least 1 cm of intact volar cortex in the distal fracture fragment for successful implementation.

Clinical research in hand surgery

Clinical research designed to enhance the quality of health care has always received a great deal of national attention. Outcomes studies, clinical trials, and evidence-based research are key components of clinical research that have advanced the field of hand surgery. The purpose of the Weiland Award is to encourage innovations and progress in clinical research in hand surgery for the betterment of patients and to promote hand surgery's visibility in American medicine. This article will highlight my efforts in clinical research through 3 specific research themes: (1) outcomes research, (2) economic analysis, and (3) evidence-based research and quality assessment in health care.

Is early internal fixation preferred to cast treatment for well-reduced unstable distal radial fractures?

BACKGROUND

In the treatment of distal radial fractures, physicians often advocate internal fixation over cast treatment for potentially unstable fracture patterns, citing the difficulties of successful nonoperative treatment and a decrease in patient tolerance for functional deficiencies. This study was performed to evaluate whether early internal fixation or nonoperative treatment would be preferred for displaced, potentially unstable distal radial fractures that initially had an adequate reduction.

METHODS

A decision analytic model was created to compare early internal fixation with use of a volar plate and nonoperative management of a displaced, potentially unstable distal radial fracture with an acceptable closed reduction. To identify the optimal treatment, quality-adjusted life expectancy was estimated for each management approach. Data from the literature were used to estimate rates of treatment complications (e.g., fracture redisplacement with nonoperative treatment) and of treatment outcomes. Mean health-state utilities for treatment outcomes of painless malunion, functional deficit, and painful malunion were derived by surveying fifty-one adult volunteers with use of the time trade-off method. Sensitivity analysis was used to determine which model parameters would change the treatment decision over a plausible range of values.

RESULTS

Early internal fixation with volar plating was the preferred strategy in most scenarios over the ranges of parameters available, but the margins were small. The older patient (mean age, 57.8 years) who sustains a distal radial fracture can expect 0.08 more quality-adjusted life years (29.2 days) with internal fixation compared with nonoperative treatment. Sensitivity analysis revealed no single factor that changed the preferred option within the reported ranges in the base case. However, the group of patients sixty-five years or older, who had lower disutility for painful malunion, derived a very small benefit from operative treatment (0.01 quality-adjusted life year or 3.7 days) and would prefer cast treatment in some scenarios.

CONCLUSIONS

Internal fixation with use of a volar plate for potentially unstable distal radial fractures provided a higher probability of painless union on the basis of available data in the literature. This long-term gain in quality-adjusted life years outweighed the short-term risks of surgical complications, making early internal fixation the preferred treatment in most cases. However, the difference was quite small. Patients, especially those over sixty-four years old, who have lower disutility for the malunion and painful malunion outcome states may prefer nonoperative treatment.

Trends in the United States in the treatment of distal radial fractures in the elderly

BACKGROUND

Traditionally, distal radial fractures in the elderly have been treated nonoperatively with casting. However, since the introduction of the volar locking plating system in 2000, there has been an interest in the use of more aggressive treatment methods. The purpose of the present study was to assess changing trends in the treatment of distal radial fractures in elderly patients in the United States.

METHODS

We evaluated a 5% sample of Medicare data from 1996 to 1997 and a 20% sample from 1998 to 2005. Information on four treatment methods (closed treatment, percutaneous pin fixation, internal fixation, and external fixation) was extracted from the dataset. Other available data were diagnosis, physician specialty, and patient age, sex, and race. We calculated frequencies and rates to compare the utilization of different treatments over time.

RESULTS

Over the ten-year time period examined, the rate of internal fixation of distal radial fractures in the elderly increased fivefold, from 3% in 1996 to 16% in 2005. Closed treatment, however, remained the predominant method (used for 82% of the fractures in 1996 and 70% in 2005). Fractures in patients with an age of eighty-five years or more were significantly more likely to be treated in a closed fashion (p < 0.0001). There was a large variation among physician specialties with regard to the fixation methods that were used. Orthopaedic surgeons were significantly more likely to use closed treatment than hand surgeons were, whereas hand surgeons were significantly more likely to use internal fixation than orthopaedic surgeons were.

CONCLUSIONS

Since 2000, although the majority of distal radial fractures are still treated nonoperatively, there has been an increase in the use of internal fixation and a concurrent decrease in the rate of closed treatment of distal radial fractures in the elderly in the United States.

A comparative study of clinical and radiologic outcomes of unstable colles type distal radius fractures in patients older than 70 years: nonoperative treatment versus volar locking plating

OBJECTIVES

To compare final functional and radiographic outcomes of closed reduction and casting (CAST) with open reduction and internal fixation (ORIF) with palmar locking plate for unstable Colles type distal radius fractures (DRFs) in low-demand patients older than 70 years.

DESIGN

Retrospective, clinical study.

SETTING

Level 1 university trauma center.

PATIENTS

Over a mean period of 4 years and 7 months, 130 consecutive patients older than 70 years were treated for an unstable dorsally displaced DRF of which 114 or 87% were followed for 1 year or longer.

INTERVENTION

ORIF (n = 53) using volar locking plate or closed reduction and casting (n = 61).

MAIN OUTCOME MEASUREMENTS

Objective and subjective functional results (active range of motion; grip strength; disabilities of the arm, shoulder and hand (DASH) score; patient-rated wrist evaluation (PRWE) score; visual analog scale; and Green and O'Brien score) and radiographic assessment (dorsal tilt, radial inclination, radial shortening, fracture union, and posttraumatic arthritis) were assessed.

RESULTS

At final follow-up, there was no significant difference between the 2 groups for mean ranges of motion, grip strength, DASH score, PRWE score, and Green and O'Brien score. Pain level was significantly less for the patients in the CAST group. An obvious clinical deformity was present in 77% of cast group and none in the ORIF group. At final follow-up, in the ORIF group, there was a mean loss of dorsal tilt of 1.3 degrees, radial inclination of 0.3 degrees, and radial length of 0.5 mm compared with the postoperative measurements. No primary acceptable reduction was achieved in 44% of the CAST group. At final follow-up, in the CAST group, dorsal tilt, radial inclination, and radial shortening averaged -24.4 +/- 12 degrees, 19.2 +/- 6.5 degrees, and +3.9 +/- 2.7 mm, respectively. Malunion occurred in 89% primarily reduced fractures. Dorsal tilt, radial inclination, and radial shortening were significantly better in the ORIF group.

CONCLUSIONS

Radiographic results (dorsal tilt, radial inclination, and radial shortening) after unstable dorsally displaced DRFs are significantly better in patients treated by ORIF using a volar fixed-angle plate rather than those treated by cast immobilization (P < 0.05). At a mean follow-up time of 4 years and 7 months, the clinical outcomes of active range of motion, the PRWE, DASH, and Green and O'Brien scores do not differ between the 2 methods of treatment. The pain level was significantly less in the CAST group (P < 0.05), and this group experienced no complications. There was no difference between the subjective and functional outcomes for the surgical and the nonsurgical treatments in a cohort of patients older than 70 years. Unsatisfactory radiographic outcome in older patients does not necessarily translate into unsatisfactory functional outcome. Nonoperative treatment may be the preferred method of treatment in this age group.
