Management of complications of distal radius fractures

Volar fixed plating of distal radius fractures: optimizing plate position for enhanced clinical outcomes

BACKGROUND

The precise influence of plate position on clinical outcomes in the context of volar fixed-angle plating for distal radius fractures is not fully understood. This article aims to investigate the influence of plate position on clinical results, and functional outcomes in patients treated with volar fixed plating for distal radius fractures.

METHODS

A total of 58 patients with 64 distal radius fractures were included in the study. Patient demographics, fracture characteristics, surgical details, and radiographic data were collected. Post-operative AP and Lat views of all patients taken on the first day after surgery were evaluated. Volar Tilt, Radial Inclination and Radial Height measurements were used as reduction criteria. In the follow-up, the patients were called for their last control, flexion and extension angles of the wrist and Mayo Wrist Scores, the distance of the plate to the joint line and the angle between the plate and the radial shaft were measured and recorded.

RESULTS

A total of 64 distal radius fractures, with a mean age of 46.9 years, and the mean follow-up period 24.9 months were included in this study. There was a significant relationship between the Radial Inclination and Plate-Shaft Angle variables and the Mayo Wrist Score at a 99% confidence interval. Additionally, a relationship was observed between the Radial Height variable and the Mayo Score at a 90% confidence interval. A significant positive association was observed between radial inclination and achieving a Good-to-Excellent Mayo score (OR = 1.28, 95% CI [1.08-1.51], p = 0.004). Plate distance to joint line demonstrated a marginally significant positive association with a Good-to-Excellent Mayo score (OR = 1.31, 95% CI [0.97-1.77], p = 0.077). Univariate analysis revealed a significant negative association between plate-shaft angle and achieving a Good-to-Excellent Mayo score (OR = 0.71, 95% CI [0.52-0.99], p = 0.045). This negative association remained statistically significant in the multivariate analysis (p = 0.016).

CONCLUSION

Radial inclination, plate distance to joint line, and angle between plate and radius shaft were identified as significant factors associated with improved Mayo Wrist Scores.

Current clinical practice patterns and perspectives of Australian hand therapists during the treatment of adults with distal radius fracture: A national survey

INTRODUCTION

Successful return to pre-injury occupational performance following distal radius fracture (DRF) may be influenced by person and environment factors such as pain, age, social support, and socioeconomic status. The primary aim of this study was to explore Australian hand therapists' current clinical practice and determine whether they consider these factors during the management of DRF.

METHODS

A mixed methods online survey was distributed to members of the Australian Hand Therapy Association. Descriptive statistics were used to examine the quantitative data, and the qualitative data were analysed by content analysis.

RESULTS

Of the 120 members who completed the survey, 68% were occupational therapists and 32% were physiotherapists with 74% in the private and 26% in the public health-care setting. Most factors perceived to influence recovery were consistent with person factors and a biomechanical approach. Other factors related to occupational performance, such as social and leisure skills, environment and culture were reported less often. When asked about defining occupational performance, the key categories identified through qualitative open responses were 'performing meaningful activities/occupations', 'performing work/employment', and 'completing activities/function'.

CONCLUSION

The data suggest that hand therapists in Australia primarily identify person factors as key to recovery after DRF. Context and environmental factors that influence occupational performance did not appear to be considered as often during treatment or when defining occupational performance. Further research is needed to explore the contextual and environmental factors that influence hand therapy intervention and determine whether they play a role in the successful return to pre-injury occupational performance following DRF.

CONSUMER AND COMMUNITY INVOLVEMENT

The survey was conceptualised by the research team, which included two experienced hand therapists and piloted with 10 consumers. Hand therapists (consumers) of various years of experience and discipline (i.e., occupational therapy and physiotherapy) provided feedback to improve the survey in terms of content, comprehensibility, and length. No clients/patients of hand therapists were involved in the development of the survey or the study, and the consumers of the study were considered hand therapists.

Three-dimensional imaging of the forearm and hand: A comparison between two 3D imaging systems

The conventional treatment for distal radius fractures typically involves immobilization of the injured extremity using a conventional forearm cast. These casts do cause all sorts of discomfort during wear and impose life-style restrictions on the wearer. Personalized 3D printed splints, designed using three-dimensional (3D) imaging systems, might overcome these problems. To obtain a patient specific splint, commercially available 3D camera systems are utilized to capture patient extremities, generating 3D models for splint design. This study investigates the feasibility of utilizing a new camera system (SPENTYS) to capture 3D surface scans of the forearm for the design of 3D printed splints. In a prospective observational cohort study involving 17 healthy participants, we conducted repeated 3D imaging using both the new (SPENTYS) and a reference system (3dMD) to assess intersystem accuracy and repeatability. The intersystem accuracy of the SPENTYS system was determined by comparison of the 3D surface scans with the reference system (3dMD). Comparison of consecutive images acquired per device determined the repeatability. Feasibility was measured with system usability score questionnaires distributed among professionals. The mean absolute difference between the two systems was 0.44 mm (SD:0.25). The mean absolute difference of the repeatability of the reference -and the SPENTYS system was respectively 0.40 mm (SD: 0.30) and 0.53 mm (SD: 0.25). Both repeatability and intersystem differences were within the self-reported 1 mm. The workflow was considered easy and effective, emphasizing the potential of this approach within a workflow to obtain patient specific splint.

Flexor Pollicis Longus Reconstruction After Rupture Following Distal Radius Fixation With Volar Locking Plate: A Technique Guide

Flexor pollicis longus rupture is an uncommon but potentially debilitating complication after volar locking plate fixation of distal radius fractures, occurring secondary to tendon attrition against the implant. This nature of tendon injury typically precludes primary repair. This paper will illustrate 2 reconstruction techniques, an interpositional tendon graft and a tendon transfer, that have been utilized successfully by the authors.

Complex Regional Pain Syndrome after Distal Radius Fracture-Case Report and Mini Literature Review

This study explores the impact of the complex regional pain syndrome (CRPS) on the lives and mobility of patients, with a particular focus on its emergence as a late complication of distal radius fractures (DRFs), a common occurrence, especially among an aging population. The absence of a standardized treatment for the CRPS and the challenge of predicting its occurrence make it a complex medical issue. This research aims to shed light on the effects of treating the CRPS through a case study involving a 75-year-old woman with untreated osteoporosis who experienced a Colles fracture after a fall. The initial management involved repositioning and stabilizing the fractured forearm with a plaster cast, followed by an operation using percutaneous pinning via a Kirschner wire. Subsequently, the patient developed CRPS symptoms and was admitted to the rehabilitation department three months post-fracture. The affected forearm exhibited swelling, warmth, pain, and severely limited range of motion. Treatment involved a combination of medications, physiotherapy, and kinesiotherapy. Significantly, the patient experienced notable improvement following these interventions. This study underscores the absence of a definitive standard for CRPS treatment but suggests that proper rehabilitation and pharmaceutical interventions can contribute positively to patient outcomes. The case further highlights the potential association between DRF and CRPS development, emphasizing the need for continued research in this field.

Hand and wrist - what the hand surgeon wants to know from the radiologist

Hand surgeons, as unique specialists, appreciate the complexity of the anatomy of the hand. A hand is not merely a group of anatomic structures but a separate organ that works by feeling, sending information to the brain, and enabling a variety of movements, from precise skills to firm tasks. Acute and chronic problems interfere with complicated hand function and potentially influence work or daily life activities for a long time. Thus, the surgeon's role is to propose appropriate treatment with predictable results. This paper attempts to specify the preoperative considerations and their influence on the choice of surgical procedure and the assessment of results potentially influencing further treatment. We have divided the manuscript by anatomical structures, which is a natural surgical assessment and planning approach. The most common problems were highlighted to introduce the method of decision-making and surgical solutions.

Is Carpal Tunnel Release Necessary in High-Energy Distal Fractures of the Radius?

Purpose This study aimed to compare the clinical outcomes of patients who underwent volar plate osteosynthesis for high-energy distal radius fracture (DRFx) and carpal tunnel release (CTR) for acute or subacute carpal tunnel syndrome (CTS) with patients who did not undergo CTR. Methods This study is a retrospective evaluation of all high-energy DRFx treated with volar plate osteosynthesis in a regional hospital between January 2021 and January 2023. All adult patients (≥18 years) who underwent open reduction and internal fixation were included in the study after obtaining approval from the internal review board of our institution. Only patients who underwent plate osteosynthesis of the volar aspect through a modified Henry incision and patients who underwent CTR through a classic separate incision were included in the study. Clinical results include hand dynamometry, visual analog scale (VAS) scores, and physical examination findings of patients who underwent volar plate osteosynthesis because of high-energy DRFx and CTR due to CTS in the acute and subacute periods were retrospectively examined. Results Among the patients who underwent volar plate osteosynthesis because of high-energy DRFx, no statistically significant difference was detected between the hand grip strength and VAS scores of patients who underwent CTR because of acute CTS and subacute CTS at the sixth postoperative week (p>0.05). Conclusion Prophylactic CTR may be performed in the same session in selected cases, such as DRFx caused by a high-energy injury, to establish a scale for DRFx at a high risk of CTS and avoid delays in treatment. CTR for transient CTS detected in the subacute period during outpatient follow-up does not improve clinical outcomes.

Complications of operatively treated distal radial fractures

Distal radial fractures represent the most common fractures of the upper extremity. Operative treatment is performed for approximately one-third of distal radial fractures in the adult population. Complications following operative treatment of distal radial fractures vary depending on the treatment modality and can be stratified into preoperative and postoperative complications. Complications can occur in the near, intermediate and long term. The most common complications seen are tendon irritation and rupture, chronic regional pain syndrome (CRPS), carpal tunnel syndrome, ulnar or radial neuropathy, compartment syndrome, malunion, inadequate fixation or loss of fixation, symptomatic hardware, post-traumatic arthritis, stiffness and infection. Careful planning, treatment and patient selection can help to mitigate these complications.Level of evidence: V.

This case report explores the efficacy of reconstructive surgical intervention in addressing malunited fractures of the distal end of the radius and ulna. The study presents a detailed analysis of a specific case, highlighting the surgical techniques employed and their impact on patient outcomes. The report emphasizes the importance of precision in addressing malunited fractures and showcases how the intervention led to improved patient outcomes. By documenting this case, the study contributes valuable insights into the field of orthopedic surgery, providing a basis for further research and enhancing the understanding of optimal approaches to managing such complex fractures.

Flexor pollicis longus tendon rupture: a case series on palmaris longus tendon graft reconstruction after volar plate fixation

Flexor pollicis longus (FPL) tendon rupture is a debilitating condition that can impair hand function. This case series study aimed to evaluate the outcomes of FPL tendon rupture and subsequent palmaris longus (PL) tendon graft reconstruction. Three cases of FPL tendon rupture in patients who had previously undergone open reduction and internal fixation with a volar plate were included. The surgical intervention involved volar plate removal, tenolysis and PL tendon graft reconstruction. Follow-up assessments showed gradual improvement in wrist function, with no post-operative complications or infections observed. These findings suggest that PL tendon grafting can be an effective surgical technique for FPL tendon rupture. Further research is needed to determine optimal surgical approaches and post-operative rehabilitation protocols for this condition.

The Morphology and Morphometric Analysis of the Radius Bone: A Study on Freshly Frozen Cadavers in the Indian Population

Introduction The radial bone and the radioulnar joint are vital for the physiological and physical stability of the elbow. The prostheses and plates used in cases of radius fracture are designed based on the morphology of the Western population. This could result in a bone-implant mismatch when applied to the Indian population, resulting in complications. Hence, the study aimed to record the normal values of radius morphology in the Indian population. Methods A total of 30 (eight male and seven female) freshly frozen cadaveric bilateral upper limbs were chosen. Cadavers with previous surgical scars, deformities, and congenital defects of the upper limb were excluded. The radius was excised, and morphometric parameters were measured with a non-elastic measuring tape and a digital caliper and recorded using GeoGebra software. Results All measuring parameters exhibited no significant difference between the right and left side of the bone (p > 0.05), whereas the difference between males and females for most parameters was statistically significant (p < 0.05). The mean difference between the anteroposterior (AP) diameter and transverse diameter of the radial head for the study sample was 0.89 ± 0.06 mm. Thus, the AP diameter was 4% greater than the transverse diameter. The head of the radius was observed to be almost round. The degree of extent of the safe zone was 124.64°, with an average safe arc length of 3.27 ± 0.55 cm. Conclusion The morphometric measurements of the radius in the Indian population are different from the Western population.

Does Radiographic Alignment Correlate With Patient-Reported Functional Outcomes and Posttreatment Complications in Older Patients Treated for Wrist Fractures?

PURPOSE

Surgical treatment of distal radius fractures provides better fracture alignment than closed reduction; however, surgical treatment does not lead to better patient-reported function at 12 months. The aims of this study were to report the radiographic outcomes from the Combined Randomized and Observational Study of Surgery for Fractures In the distal Radius in the Elderly trial, investigate the association between radiographic outcomes and patient-reported function, and explore whether this association was affected by posttreatment complications and direction of malalignment.

METHODS

This study used the outcomes of the Combined Randomized and Observational Study of Surgery for Fractures In the distal Radius in the Elderly trial, which is a combined randomized and observational trial that compared volar-locking plate fixation with closed reduction and cast immobilization, to treat distal radius fractures in patients aged ≥60 years. Four radiographic outcomes (dorsal angulation, radial inclination, ulnar variance, and articular step) were reported at the following three time frames: (1) baseline, (2) after treatment, and (3) ≥6 weeks by treatment group. Secondary analysis was correlation of 12-month patient-reported function scores with 6-week radiographic measures for each of four radiographic parameters, and a subgroup analysis was conducted to investigate if this was affected by posttreatment complications. Tertiary analysis investigated if direction of malalignment affected the secondary analysis.

RESULTS

We recruited 300 participants (166 randomized and 134 observational); 113 had volar-locking plate fixation, and 187 had closed reduction. There were no between-group differences for each of the four pretreatment radiographic parameters, but there were between-treatment group differences for all four radiographic parameters apart from articular step. We found no association between patient-reported function at 12 months and each of the four radiographic parameters at 6 weeks. This lack of association was unaffected by posttreatment complications and the direction of malalignment.

CONCLUSIONS

For patients with wrist fractures aged ≥60 years, final radiographic alignment did not correlate with patient-reported function at 12 months. These findings were not affected by treatment type, and there was no association between radiographic alignment and posttreatment complications.

Blood Flow Restriction Therapy for Use After Extremity Fracture: A Critically Appraised Topic

CLINICAL SCENARIO

Blood flow restriction (BFR) therapy has emerged as a viable treatment option to enhance clinical recovery in patients with primarily muscular injuries. However, BFR therapy has been rarely investigated in patients with osseous injuries to include extremity fracture.

FOCUSED CLINICAL QUESTION

Does BFR-enhanced therapy improve clinical outcomes in patients during the acute to subacute rehabilitation period after extremity fracture?

SUMMARY OF KEY FINDINGS

(1) In cases of 2 high-performing athletes with talus and osteochondral fracture of the knee, BFR was well tolerated and an effective rehabilitation regimen. (2) In 2 randomized controlled trials evaluating BFR use in patients after operative and nonoperative management of distal radius fractures, pain with activity and self-perceived function were improved in BFR-enhanced therapy as compared with a standard rehabilitation regimen. (3) Objective clinical outcomes including radiographic healing, extremity range of motion, and grip strength evaluated by the randomized controlled trials did not differ significantly between the BFR-enhanced and standard rehabilitation groups.

CLINICAL BOTTOM LINE

BFR-enhanced therapy may improve pain and self-perceived function of the injured extremity during the acute to subacute rehabilitation period after fracture. However, there is not yet a demonstrated benefit of BFR on hastening objective measures of clinical recovery. Large-scale clinical trials comparing BFR-enhanced rehabilitation with standard rehabilitation regimens are needed to better characterize BFR use in patients with osseous injuries.

STRENGTH OF RECOMMENDATION

Two case reports and 2 randomized controlled trials provide level IIB evidence suggesting that BFR may improve pain in the acute rehabilitative stage and improve the patient's perceived function of the injured extremity, without greater improvement in objectively measured clinical parameters as compared with a standard rehabilitation regimen.

Chronic post-traumatic pain: rheumatological and orthopedic aspects

Trauma causes a complex local and systemic reaction of the macroorganism, the consequences of which can be various functional, neurological and psychoemotional disorders. One of the most painful complications of injuries of the musculoskeletal system is chronic post-traumatic pain (CPTP), which occurs, depending on the severity of the damage, in 10–50% of cases. The pathogenesis of this syndrome is multifactorial and includes the development of chronic inflammation, degenerative changes (fibrosis, angiogenesis, heterotopic ossification), pathology of the muscular and nervous systems, neuroplastic changes leading to the development of central sensitization, as well as depression, anxiety and catastrophization. Risk factors for CPTP should be considered the severity of injury, comorbid diseases and conditions (in particular, obesity), stress and serious trauma-related experiences (within the framework of post-traumatic stress disorder), the development of post-traumatic osteoarthritis and chronic tendopathy, genetic predisposition, deficiencies in treatment and rehabilitation in the early period after injury. To date, there is no clear system of prevention and treatment of CPTP. Considering the pathogenesis of this suffering, adequate anesthesia after injury, active anti–inflammatory therapy (including local injections of glucocorticoids), the use of hyaluronic acid, slow-acting symptomatic agents and autologous cellular preparations – platelet-riched plasma, mesenchymal stem cells, etc. are of fundamental importance. However, therapeutic and surgical methods of CPTP control require further study

Evaluation of the Coronal Malposition of the Volar Locking Plate in the Treatment of Distal Radius Fractures

Background and objectives: Literature does not show any studies regarding plate placement problems in the coronal plane of patients with volar plating due to distal radius fracture diagnosis. We aimed to investigate the functional and laboratory results of the coronal malposition of the volar locking plate in patients with distal radius fracture treated with internal fixation.

Methods: In this retrospective study, we included patients who had volar plate fixation, were aged between 18 and 80, had no pathological fracture, had a minimum of six months of follow-up, and had the same rehabilitation protocol. We consider the angle subtended on the coronal axis between the distal radius long axis and the distal radius locking plate as coronal malposition. We named the coronal malposition angle the "AYE Angle." Patients with an AYE angle of over 1 degree were evaluated under group 1. Patients with an AYE angle of 0-1 degrees were evaluated under group 2. Radiological parameters were taken from AP-Lateral X-ray views. Superficial University System of Georgia (USG) examinations were applied to detect tendon problems. The DASH and QUICK-DASH scoring systems were used for clinical evaluation. Grip strength was measured with a dynamometer in all patients. All results were compared between the two groups.

Results: Thirteen patients were female and 27 patients were male. Nineteen patients who had coronal malposition were added to group 1, while 21 patients who had no coronal malposition were added to group 2. Fifteen patients had normal USG results in group 2, while 18 patients had edema around the flexor pollicis longus (FPL) tendon as a result of USG in group 1. Statistically, a significant difference was detected between the two groups in terms of the amount of tenosynovitis around FPL (p=0.01).

A statistically significant relationship was found between USG grading and malposition grading. The study revealed that a higher rate of USG grade 2 was found in patients with malposition grade 2 (90.9%), while a higher rate of USG grade 1 (50%) was observed in patients with malposition grade 1 (p=0.01).

A statistically significant difference was not found between Soong grading and USG in terms of the level of tenosynovitis around the FPL tendon. The amount of tenosynovitis detected around the FPL tendon was 62.5% for Soong and grade 0 level, 60.7% for grade 1 level, and 50% for grade 2 level. There was no statistically significant difference between the two groups in the DASH and QUICK-DASH scoring systems (p=0.96). There was no statistically significant difference between the two groups in the grip strength (p=0.52).

Conclusion: Coronal plate position in the treatment of the distal radius fracture is important to avoid potential flexor tendon problems. The volar plate position should be adjusted properly both in the coronal and sagittal axes.

Implant Removal Due to Infection After Open Reduction and Internal Fixation: Trends and Predictors

BACKGROUND

Implant removal due to infection is one of the major causes failure following open reduction and internal fixation (ORIF). The aim of this study was to determine trends and predictors of infection-related implant removal following ORIF of extremities using a nationally representative database.

METHODS

Nationwide Inpatient Sample data from 2006 to 2017 was used to identify cases of ORIF following upper and lower extremity fractures, as well as cases that underwent infection-related implant removal following ORIF. Multivariate analysis was performed to identify independent predictors of infection-related implant removal, controlling for patient demographics and comorbidities, hospital characteristics, site of fracture, and year.

RESULTS

For all ORIF procedures, the highest rate of implant removal due to infection was the phalanges/hand (5.61%), phalanges/foot (5.08%), and the radius/ulna (4.85%). Implant removal rates due to infection decreased in all fractures except radial/ulnar fractures. Tarsal/metatarsal fractures (odds ratio (OR)=1.45, 95% confidence interval (CI): 1.02-2.05), and tibial fractures (OR=1.82, 95% CI: 1.45-2.28) were identified as independent predictors of infection-related implant removal. Male gender (OR=1.67, 95% CI: 1.49-1.87), Obesity (OR=1.85, 95% CI: 1.34-2.54), diabetes mellitus with chronic complications (OR=1.69, 95% CI: 1.13-2.54, P<0.05), deficiency anemia (OR=1.59, 95% CI: 1.14-2.22) were patient factors that were associated with increased infection-related removals. Removal of implant due to infection had a higher total charge associated with the episode of care (mean: $166,041) than non-infection related implant removal (mean: $133,110).

CONCLUSION

Implant removal rates due to infection decreased in all fractures except radial/ulnar fractures. Diabetes, liver disease, and rheumatoid arthritis were important predictors of infection-related implant removal. The study identified some risk factors for implant related infection following ORIF, such as diabetes, obesity, and anemia, that should be studied further to implement strategies to reduce rate of infection following ORIF.

Post-arthrolysis rehabilitation in a patient with wrist stiffness secondary to distal radio-ulnar fracture: A case report

BACKGROUND

Arthrolysis is usually performed when stiffness has a disabling effect on quality of life and in cases where physiotherapy has not been effective. This report describes one patient with a chronic stiff wrist who underwent open arthrolysis. The purpose of this case report is to describe the rehabilitation following arthrolysis, in order to illustrate the effects of intensive physiotherapy for this patient.

CASE DESCRIPTION

A 54-year-old woman with chronic wrist stiffness secondary to a radio-ulnar fracture was described. The patient presented severe pain and unsatisfactory wrist range of motion and muscle strength almost 2 years after the traumatic event.

INTERVENTION

Post-arthrolysis rehabilitation was based on edema control, manual therapy, transcutaneous electrical nerve stimulation (TENS), static splinting and strengthening exercises. In addition, graded motor imagery and proprioceptive rehabilitation were included to address impaired motor control. Outcome measures of passive range of motion (PROM), active range of motion (AROM), grip and pinch strength, numeric rating scale (NRS), disability of the arm, shoulder and hand (DASH) and patient-rated wrist/hand evaluation (PRWHE) were recorded.

CONCLUSIONS

The outcomes of this case report suggest that arthrolysis combined with immediate and intensive physiotherapy were a suitable option for the treatment of post-traumatic wrist stiffness in this patient. The passive motion measured intraoperatively was maintained, while pain, functional active motion and strength were improved allowing for social reintegration.

Tronco-conical locking plate in distal radius fractures

INTRODUCTION

Volar locked plates represent the most popular fixation technique for distal radius fracture (DRF). However, threaded screw-hole angular stability mechanism has some issues. The purpose of our study is to evaluate clinical and radiological outcome of a tronco-conical locking mechanism for volar plating of DRF.

MATERIALS AND METHODS

Eighty patients with DRF treated with tronco-conical locking volar plates between May 2013 to December 2017 in two institutions were collected. We analysed clinical and radiological outcomes and peri-operative complications, like loss of reduction, fragment displacement, deformation or implant-related problems and surgical and other general complications.

RESULTS

78 patients were available for at final follow-up. The average follow-up period was 11.4 months (range, 6-18 months). All fractures healed within three months. Five cases of final reductions were defined unsatisfying. According to Gartland and Werley's scoring system at final follow up, 36 patients had excellent results, 40 patients had good results, one patient had fair and one patient had poor results. Five complications were observed. No complications were observed during surgical plate removal.

CONCLUSION

Complications found in our study are not related to tronco-conical locking mechanism and are like those found in the literature. Further studies are needed to evaluate functional results or radiographic parameters of this new type of angular stability mechanism. Tronco-conical locking plate is an attractive alternative threaded screw-hole angular stability mechanism.

Trends in the Incidence and Treatment of Distal Radius Fractures in the United States in Privately Insured and Medicare Advantage Enrollees

Background: This study aims to determine the trends in the treatment of distal radius fractures (DRFs) in patients aged 18 years and older. Methods: An administrative claims database of more than 100 million patients was used to identify patients aged 18 years and older with a DRF between 2005 and 2014. A total of 137 130 DRFs were identified in 135 128 patients. Results: The proportion and rate of fractures were more predominant in those aged 55 years and older compared with a decreasing incidence in patients younger than 55 years. Age-adjusted rates of surgical treatment have significantly increased in both women and men by 15.9% (absolute change, 4.8%) and 5.0% (absolute change, 1.7%) change over time, respectively. Conversely, age-adjusted rates of nonsurgical treatment have significantly decreased overtime in both women and men by 6.9% and 2.6%, respectively. Conclusions: These data provide better understanding of the epidemiology of DRF, which is important to develop preventive strategies targeting high-risk populations and to develop effective treatment strategies.

Effectiveness of prophylactic vitamin C supplementation in the prevention of complex regional pain syndrome after distal end radius fractures in the aging population

Background/purpose

Vitamin C has been proposed to prevent the incidence of complex regional pain syndrome, but the results are conflicting. We evaluated the effectiveness of vitamin C in the prevention of complex regional pain syndrome-1 after distal end radius fractures in the aging population.

Methods

This was a prospective, randomized study. Patients treated with either conservative or surgical management for distal end radius fracture received Vitamin C (500 mg/day) plus standard therapy or standard therapy alone for a period of 3 months. The presence of complex regional pain syndrome-1 was assessed with Budapest criteria.

Results

The complex regional pain syndrome-I occurred in 11.3% in Vitamin C plus Standard in compared to 26% in Standard therapy alone. Vitamin C was significantly associated with a reduction in the likelihood of exhibiting complex regional pain syndrome-1.

Conclusion

Vitamin C (500 mg/day) supplementation was effective and associated with a lower occurrence of acute complex regional pain syndrome-1. It can be a promising prophylactic option for the prevention of complex regional pain syndrome-1 after distal end radius fracture.

Upper-Extremity Venous Thromboembolism Following Operative Treatment of Distal Radius Fractures: An Uncommon but Dangerous Complication

PURPOSE

Distal radius fractures are the most common long bone fracture in the United States, with an estimated incidence of 640,000 cases per year. Operative fixation presents a theoretical risk factor for the development of upper-extremity venous thromboembolism (UE-VTE). Additionally, patients presenting with distal radius fracture commonly have preexisting comorbidities that further increase the risk of UE-VTE. Finally, UE-VTE is considered the highest risk for eventual development of pulmonary embolism. Despite this, scant attention has been paid to studying UE-VTE in this population. The purpose of this study was to measure the incidence of this complication and to identify possible medical factors that increased the risk of developing UE-VTE.

METHODS

We queried the Truven MarketScan Commercial Claims and Encounters Database for all patients who experienced a distal radius fracture and were subsequently treated with open reduction and internal fixation between 2012 and 2016. Patients were identified using relevant Common Procedural Terminology codes. Demographic and medical variables were tabulated. Our primary outcome was the development of ipsilateral UE-VTE or pulmonary embolism in the first 60 days after surgery.

RESULTS

The study included 24,494 patients. The mean age was 50.7 years (range, 18-91), and 58% were women. There were 79 cases (0.3%) of UE-VTE and 19 cases of pulmonary embolism in the study population (24.1% of all UE-VTE cases; 0.08% of total sample). Multivariable logistic regression showed that coexisting heart failure and estrogen use were associated with increased risk of UE-VTE.

CONCLUSIONS

Although uncommon, the development of UE-VTE after open reduction and internal fixation for distal radius fractures is a concerning complication. Coexisting heart failure and estrogen use are associated with increased risk of UE-VTE.

Treatment of Infected Nonunion of Distal Radius with Concurrent Distal Radioulnar Joint Disruption: A Case Report

CASE

A 37-year-old farmer presented with previously operated open type 2 infected nonunion of distal radius. A wrist-spanning external fixator was applied after implant removal, debridement, and postoperative antibiotics for 6 weeks. At 6 weeks' follow-up, a volar locking plate and bone grafting for the gap nonunion over distal radius and the modified Sauve-Kapandji procedure for distal radioulnar joint (DRUJ) were performed. The patient had excellent results at 3 years' follow-up.

CONCLUSION

Distal radius nonunion with disrupted DRUJ can be treated with internal fixation, and the modified Sauve-Kapandji technique provided thorough debridement is performed.

A Comprehensive Evaluation of the Readability of Online Healthcare Materials Regarding Distal Radius Fractures

Introduction

Distal radius fractures (DRFs) are among the most common upper limb fractures reviewed in the emergency and orthopaedic departments. Approximately 40% of these fractures are unstable and require fixation to improve limb function. Confronted with an impending operation, many patients will access the internet, looking for information and reassurance. Previous studies have suggested that orthopaedic healthcare websites are beyond the comprehension of their target audience.

Objective

To assess the readability of healthcare websites regarding DRFs.

Methods

The terms distal radius fracture, broken wrist and wrist fracture were searched on Google and Bing. Of 101 websites initially considered, 52 unique websites underwent evaluation using readability software. Websites were assessed using two common methods for assessing readabilty; the Reading Grade Level (RGL) and the Flesch Reading Ease Score (FRES). In line with recommended guidelines and previous studies, an RGL of sixth grade and under and a FRES score above 65 was considered acceptable.

Results

The mean score for the FRES index was 56.67 (SD: ± 19.6), which resulted in the majority of pieces assessed being classified as ‘fairly difficult to read'. The mean RGL was 8.61 (SD: ± 2.86); 17.3% of the websites assessed fulfilled the criteria of having an RGL of six or less. One way T-tests comparing the FRES and RGL mean scores against the acceptable standards showed that they failed to meet the acceptable indexes (FRES: P<0.004; 95% CI: -13.8 to -2.8; RGL: P<0.0001; CI: 1.8-3.4). ANOVA testing showed no significant difference based on category (FRES: P=0.791; RGL: P=0.101).

Conclusion

The level of comprehension required for online healthcare education materials related to distal radius fractures exceeds the recommended guidelines. Improving the readability content of these websites would enhance the internet’s usability as an educational tool as well as improve patient post-operative outcomes.

The demographics and outcomes in patients with bilateral distal radius fractures

Although distal radius fractures are quite common, bilateral distal radius fractures seldomly occur. Due to this, treatment is primarily based on surgeon experience with unilateral fractures, however bi- lateral fractures add a level of complexity : loss of functional independence. The purpose of this study was to examine a cohort of patients with bilateral distal radius fractures to identify differences in demographics, mechanism of injury, and outcomes to further our understanding of these rare injuries. 23 patients were identified retrospectively over a 5-year period that met inclusion criteria. The medical records were reviewed with multiple demographic and clinical parameters recorded and analyzed. Males were more likely to sustain high-energy mechanisms (80% vs. 53%). Patients <50 years old were more likely to sustain high-energy mechanisms (90% vs. 46%) and were more likely to be treated operatively (80% vs. 62%). The most commonly associated injury was a head injury (30%). All patients treated non-operatively reported minimal/no pain upon final follow-up where 57% of patients treated operatively noted regular pain. 75% of patients with medical comorbidities had minimal/no pain upon final follow- up. Conclusions : Patients with bilateral fractures were more likely to be younger males who suffered from higher energy mechanisms. Age was a critical factor in determining treatment strategy. Rates of associated head injuries were elevated, which is an important factor for the clinician to keep in mind when treating this population. As we further our understanding of this unique population, we can improve our treatment approaches and subsequently attain better outcomes.

Successful Closed Reduction of Distal Radius Volar Locking Plate Plastic Deformation with Associated Fracture: A Case Report

CASE

Distal radius fractures are among the most common orthopaedic injuries. The volar locking plate is now the most utilized internal fixation method for these fractures. There are few reports of mechanical failure of volar locking plates within the literature. In this case report, we describe successful closed reduction of traumatic volar locking plate plastic deformation with associated fracture. In addition, we discuss existing literature regarding plastic deformation of distal radius plates.

CONCLUSION

Traumatic, plastic deformation of distal radius volar locking plates with associated fracture may be managed nonoperatively with closed reduction.

Cost-Effectiveness of Treatments after Closed Extraarticular Distal Radius Fractures in Older Adults from the WRIST Clinical Trial

BACKGROUND

This study performs an economic analysis of volar locking plate, external fixation, percutaneous pinning, or casting in elderly patients with closed distal radius fractures.

METHODS

This is a secondary analysis of the Wrist and Radius Injury Surgical Trial, a randomized, multicenter, international clinical trial with a parallel nonoperative casted group of patients older than 60 years with surgically indicated, extraarticular closed distal radius fractures. Thirty-Six-Item Short-Form Health Survey-converted utilities and total costs from Medicare were used to calculate quality-adjusted life-years and incremental cost-effectiveness ratio.

RESULTS

Casted patients were self-selected and older (p < 0.001) than the randomized surgical cohorts, but otherwise similar in sociodemographic characteristics. Quality-adjusted life-years for percutaneous pinning were highest at 9.17 and external fixation lowest at 8.81. Total costs expended were $16,354 for volar locking plates, $16,012 for external fixation, $11,329 for percutaneous pinning, and $6837 for casting. The incremental cost-effectiveness ratios for volar locking plates and external fixation were dominated by percutaneous pinning and casting. The ratio for percutaneous pinning compared to casting was $28,717. Probabilistic sensitivity analysis revealed a 10, 5, 53, and 32 percent chance of volar locking plate, external fixation, percutaneous pinning, and casting, respectively, being cost-effective at the willingness-to-pay threshold of $100,000 per quality-adjusted life-year.

CONCLUSIONS

Casting is the most cost-effective treatment modality in the elderly with closed extraarticular distal radius fractures and should be considered before surgery. In unstable closed fractures, percutaneous pinning, which is the most cost-effective surgical intervention, may be considered before volar locking plates or external fixation.

Effect of Downsized Screw Selection on Bone Healing and Postoperative Complications in Volar Plating of Distal Radius Fractures

When performing volar plating of distal radius fractures, selecting downsized subchondral screws may prevent dorsal screw penetration (DSP), which is a risk factor for extensor tendon rupture. However, downsizing may cause loss of reduction or poor bone healing. This prospective study investigated the effect of downsized screw selection on bone healing and postoperative complications. A total of 115 patients with postoperative follow-up longer than 6 months comprised the study population. Using a depth gauge, screws that were 2-mm shorter than the measured value were selected. The DSP then was checked using dorsal tangential view (DTV) radiographs during surgery and at final follow-up. Baseline data included bone healing, loss of reduction of radiological parameters, DSP location, and postoperative complications. To assess DSP on DTV radiographs, the dorsal surface of the radius was divided into the radial and ulnar sides at the Lister tubercle, and each was further divided into 2 equal regions. These 4 regions were defined as zones 1 to 4 from the radial side. A total of 114 patients (99%) showed bone healing. Mean loss of reduction was approximately 1° and within 1 mm in radiological parameters. Eleven patients (9.6%) showed DSP during surgery or at final follow-up despite using 2-mm downsized screws. The most common site of DSP was zone 3. Extensor pollicis longus rupture occurred in 2 patients (1.7%) despite no DSP. Downsized screw selection provided a high rate of bone healing with minimum loss of reduction and a low complication rate. The extensor tendon can be torn regardless of DSP.

Complications of Volar Plating of Distal Radial Fractures: A Review

Although the overall complication rate of volar plating approaches 15%, less than 5% require reoperation. Certain factors involving the patient, the fracture, and/or the surgeon may affect the overall complication risk. Patient factors, including body mass index greater than 35 and diabetes mellitus, may increase complication risk with volar plating, but older patient age does not seem to significantly alter risk.

Comparison of 24-Month Outcomes After Treatment for Distal Radius Fracture: The WRIST Randomized Clinical Trial

IMPORTANCE

Distal radius fractures (DRFs) are common injuries among older adults and can result in substantial disability. Current evidence regarding long-term outcomes in older adults is scarce.

OBJECTIVE

To compare outcomes across treatment groups at 24 months among adults with DRFs who participated in the WRIST trial.

DESIGN, SETTING, AND PARTICIPANTS

The Wrist and Radius Injury Surgical Trial (WRIST) randomized, international, multicenter trial was conducted from April 1, 2012, through December 31, 2016. Participants were adults aged 60 years or older with isolated, unstable DRFs at 24 health systems in the US, Canada, and Singapore. Data analysis was performed from March 2019 to March 2021.

INTERVENTIONS

Participants were randomized to open reduction and volar locking plate system (VLPS), external fixation with or without supplementary pinning (EFP), and percutaneous pinning (CRPP). The remaining participants chose closed reduction and casting.

MAIN OUTCOMES AND MEASURES

The primary outcome was the 24-month Michigan Hand Outcomes Questionnaire (MHQ) summary score. Secondary outcomes were scores on the MHQ subdomains hand strength and wrist motion.

RESULTS

A total of 304 adults were recruited for the study, and 187 were randomized to undergo surgery, 65 to VLPS, 64 to EFP, and 58 to CRPP; 117 participants opted for closed reduction and casting. Assessments were completed at 24 months for 182 participants (160 women [87.9%]; mean [SD] age, 70.1 [8.5] years). Mean MHQ summary scores at 24 months were 88 (95% CI, 83-92) for VLPS, 83 (95% CI, 78-88) for EFP, 85 (95% CI, 79-90) for CRPP, and 85 (95% CI, 79-90) for casting, with no clinically meaningful difference across groups after adjusting for covariates (χ23 = 1.44; P = .70). Pain scores also did not differ across groups at 24 months (χ23 = 2.64; P = .45). MHQ summary scores changed from 82 (95% CI, 80-85) to 85 (95% CI, 83-88) (P = .12) between 12 and 24 months across groups. The rate of malunion was higher in the casting group (26 participants [59.1%]) than in the other groups (4 participants [8.0%] for VLPS, 8 participants [17.0%] for EFP, and 4 participants [9.8%] for CRPP; χ23 = 43.6; P < .001), but malunion was not associated with the 24-month outcome difference across groups.

CONCLUSIONS AND RELEVANCE

The study did not find clinically meaningful patient-reported outcome differences 24 months after injury across treatment groups, with little change between 12 and 24 months. These findings suggest that long-term outcomes need not necessarily be considered in deciding between treatment options. Patient needs and recovery goals that fit to relative risks and benefits of each treatment type will be more valuable in treatment decision-making.

Fragment specific fixation with APTUS wrist system for volar rim fractures of the distal radius: a multicentric study

PURPOSE

Volar rim fractures of the distal radius are a spectrum of pathology that must be well identified and treated to achieve good outcomes and avoid surgical failures. New devices of fragment specific fixation have been developed during the last decades to fix this fragment. The purpose of this retrospective study was to evaluate the ability of APTUS^® wrist distal radius system to securely fix different types of volar rim fractures.

METHODS

Patients with at least 1 year of follow-up and a preoperative CT-scan evaluation of the fracture pattern were included in the study. Clinical, radiological and functional outcomes were assessed.

RESULTS

Sixty-eight patients with an average follow-up of 34, 1 months (12-61) were included in the study. There were no clinical and radiological complications, including loss of reduction, device failure and tendon ruptures. No patients required hardware removal. Wrist range of motion in flexion-extension averaged 96°, while in pronation-supination 144°. At final follow-up mean visual analogue scale pain was 1,8. Questionnaires, as dissabilities of the arm, shouldder and hand (DASH) score and patient-related wrist evolution (PRWE) score were 6,6 and 3 respectively. Grip strenght measured 86% compared to the normal side.

CONCLUSION

APTUS^® wrist presents a versatile set of fragment specific fixation plates able to easily and securely fix all types of volar rim fracture. The system can be used with other devices without any kind of interference between them. When correctly placed and used with the right indications, no late complications can be recorded.

Complex Regional Pain Syndrome and Distal Radius Fracture: Etiology, Diagnosis, and Treatment

Complex regional pain syndrome (CRPS) is a chronic pain condition characterized by a constellation of signs and symptoms including pain out of proportion to the injury or insult, autonomic dysfunction, trophic changes, and impaired function. CRPS may occur following either conservative or surgical management of distal radius fractures and can significantly complicate the trajectory of a patient's recovery. Although the incidence, diagnosis, prevention, and treatment of this condition have been extensively studied, optimal methods to identify, prevent, and treat this condition remain controversial. This article reviews the available literature on the diagnosis and treatment of CRPS in distal radius fractures.

Outcome Measurement for Distal Radius Fractures

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

Kirschner Wire Fixation of Distal Radius Fractures, Indication, Technique and Outcomes

Distal radius fractures are the most common upper extremity fracture that present to US emergency departments. Given the variable presentation, including age and fracture pattern, there are many techniques that have been utilized to treat them. Closed reduction and percutaneous pin (CRPP) fixation remains a viable option in extra-articular and simple intra-articular fracture patterns. CRPP techniques flourished in the mid-twentieth century until the treatment patterns shifted to primarily volar-locked plating in the twenty-first century. Although several meta-analyses have been performed comparing outcomes and complications of CRPP versus alternative methods, controversy remains over which treatments are superior.

Is Therapy Needed After Distal Radius Fracture Treatment, What Is the Evidence?

The role of hand therapy in management of distal radius fractures remains unclear. Some evidence demonstrates that initiating early range of motion and urging patients to return to routine activities of daily living as soon as possible may produce favorable outcomes that are as effective as formal supervised therapy. Extended supervised therapy does not appear to impact outcomes and a single instruction session with a home-based program produces similar results. Although we feel that formal structured therapy may have a role in select high-risk patients, the literature remains unclear on which patients would benefit most from formal supervised therapy.

Operation time effect on rates of perioperative complications after operative treatment of distal radius fractures

Purpose

The purpose is to identify the impact of operation time length on complications for patients undergoing operative treatment of distal radius fracture.

Methods

Patients who underwent operative treatments for distal radius fractures were identified in a national database. Data collected include patient demographic information, comorbidities, and complications.

Results

Operation time was found to be an independent predictor for return to the operating room. Operation time was not found to be a predictor of other postoperative complications.

Conclusion

Surgeons should work to shorten procedure duration whenever possible to minimize the risks that longer operative times can have on patient outcomes.

Manual passive rehabilitation program for geriatric distal radius fractures

Limitation of wrist range of motion (ROM) is a common complication of distal radius fractures (DRFs) in geriatric patients. The present study aimed to evaluate the effectiveness of rehabilitation in the restoration of wrist ROM after geriatric DRF. Eighty-eight geriatric patients with DRF, 59 women and 29 men aged 71.69 ± 6.232 years participated in the study. The time from wrist immobilization to rehabilitation was 12.89 ± 5.318 weeks. Daily rehabilitation was performed 30 minutes a day for 8 weeks. Active wrist ROM was measured before and at 2, 4, and 8 weeks after rehabilitation. Data were analyzed by the repeated measures multivariate analysis of variance (MANOVA), one-way MANOVA, and analysis of variance (ANOVA). Repeated measures MANOVA suggested a significant time effect for ROM (Wilks Lambda = 0.002, F = 7500.795, P < .001). Compared with before rehabilitation, each wrist ROM was significantly improved at 2, 4, and 8 weeks after rehabilitation. The one-way MANOVA demonstrated that changes in ROM were significantly different between groups (Wilks Lambda = 0.007, F = 559.525, partial eta square = 0.993, P < .001), indicating that patients in the short-term stiffness group (≤3 months) had a significantly greater increase in ROM than patients in the long-term stiffness group (>3 months). The results of this study suggest an 8-week daily rehabilitation program for geriatric patients with limited ROM <3 months after DRF.

Surgical site infections after distal radius fracture surgery: a nation-wide cohort study of 31,807 adult patients

BACKGROUND

Surgical site infections (SSI) after distal radius fracture (DRF) surgery have not previously been studied as the primary outcome in a large population with comparative data for different surgical methods. The aims of this study were 1) to compare SSI rates between plate fixation, percutaneous pinning and external fixation, and 2) to study factors associated with SSI.

METHODS

We performed a nation-wide cohort study linking data from the Swedish national patient register (NPR) with the Swedish prescribed drug register (SPDR). We included all patients ≥18 years with a registration of a surgically treated DRF in the NPR between 2006 and 2013. The primary outcome was a registration in the SPDR of a dispensed prescription of peroral Flucloxacillin and/or Clindamycin within the first 8 weeks following surgery, which was used as a proxy for an SSI. The SSI rates for the three main surgical methods were calculated. Logistic regression was used to study the association between surgical method and the primary outcome, adjusted for potential confounders including age, sex, fracture type (closed/open), and a dispensed prescription of Flucloxacillin and/or Clindamycin 0-8 weeks prior to DRF surgery. A classification tree analysis was performed to study which factors were associated with SSI.

RESULTS

A total of 31,807 patients with a surgically treated DRF were included. The proportion of patients with an SSI was 5% (n = 1110/21,348) among patients treated with plate fixation, 12% (n = 754/6198) among patients treated with percutaneous pinning, and 28% (n = 1180/4261) among patients treated with external fixation. After adjustment for potential confounders, the surgical method most strongly associated with SSI was external fixation (aOR 6.9 (95% CI 6.2-7.5, p < 0.001)), followed by percutaneous pinning (aOR 2.7 (95% CI 2.4-3.0, p < 0.001)) (reference: plate fixation). The classification tree analysis showed that surgical method, fracture type (closed/open), age and sex were factors associated with SSI.

CONCLUSIONS

The SSI rate was highest after external fixation and lowest after plate fixation. The results may be useful for estimation of SSI burdens after DRF surgery on a population basis. For the physician, they may be useful for  estimating the likelihood of SSI in individual patients.

A Biomechanical Comparison of Modified Radioscapholunate Fusion Constructs for Radiocarpal Arthritis

PURPOSE

This biomechanical study compared fixation constructs used in radioscapholunate (RSL) arthrodesis. We hypothesized that plates and screws, pin plate, and headless screws would all provide similarly stable fixation constructs.

METHODS

We chose 27 fresh-frozen cadaveric extremities, 14 of which were matched pairs and randomized them into 3 groups to match age, body mass index, and sex. An RSL arthrodesis was simulated with plates and screws, pin plates, or headless compression screws via a standard dorsal approach to the wrist. Specimens were mounted into a custom jig and cycled through an arc of 120° for 5,000 cycles to simulate 6 weeks range of motion (ROM). A 9-mm stroke differential variable reluctance transducer recorded continuous displacement, and gross hardware failure in the form of screw or pin cutout was investigated after the simulation.

RESULTS

Greater distraction across the RSL articulation was observed in the headless screws compared with the plate-and-screws and pin-plate constructs, with no difference between the plates and screws and pin plates. Greater average displacement was observed in the headless screws compared with the plate-and-screws and pin-plate constructs, with no difference between the pin plates and plates and screws. Gross hardware failure was observed least in plates and screws followed by pin plates.

CONCLUSIONS

Plate-and-screw and pin-plate constructs are biomechanically superior in resisting RSL distraction compared with headless compression screws for RSL arthrodesis over 6 weeks of simulated ROM in the absence of healing.

CLINICAL RELEVANCE

The results of this study demonstrated negligible arthrodesis site distraction in the plate-and-screws and pin-plate constructs when 6 weeks of ROM was simulated. When translated to a clinical scenario, these findings may allow earlier discontinuation of external immobilization after surgery.

Haematoma block: a safe method for pre-surgical reduction of distal radius fractures

BACKGROUND

The haematoma block (HB) has been successfully used to minimise pain prior to otherwise painful closed reduction manoeuvres for distal radius fractures. However, the invasive manner of the procedure, which technically produces an open fracture, still raises the question, whether HBs increase the risk of infection compared to conventional intravenous analgesia (IA). The purpose of this study was to assess complication rates and safety of the HB procedure for the closed reduction of surgically treated distal radius fractures.

METHODS

We included 176 distal radius fractures in 170 patients in a retrospective mono-centric study, who underwent closed reduction and casting followed by definitive surgical care over a period of two years. Patients either received a HB or IA before closed reduction and were evaluated for minor and major complications over a follow-up period of four years.

RESULTS

Overall, 42 distal radius fractures were treated with a HB (23.9%) and 134 with IA (76.1%) before closed reduction. There were a single major (2.3%) and eight minor (19%) complications observed in the HB group compared to two major (1.4%) and 24 minor (17.9%) complications in the IA group. No significant differences were identified between the two groups. Sex and type of fracture had no effect on complication rates, however, younger patients experienced higher complication rates in comparison to older ones (p = 0.035).

CONCLUSION

According to our data, the apprehensions that clinicians may have of creating open fractures through HB procedures, are unnecessary and may be abandoned confidently.

Habitual volar dislocation of the ulnar head with a locked distal radioulnar joint after distal radius fracture: A case report

RATIONALE

Habitual volar dislocation of the ulnar head with a locked distal radioulnar joint (DRUJ) is a rare complication after distal radius fracture. We present a case of habitual volar dislocation of the ulnar head in a woman with a dorsally displaced malunited distal radius fracture.

PATIENT CONCERNS

A 72-year-old woman presented with occasional painful locking of the forearm in full supination. She had fractured the left distal radius in a fall 6 months previously. The fracture had been treated non-surgically with wrist immobilization in a long and short arm cast for 6 weeks. Physical examination showed no swelling of the left hand. The wrist locked when the forearm was fully supinated, and the patient was not able to pronate her forearm without reducing the ulna by pressing the left ulna down toward the DRUJ. She experienced sharp pain during the reduction procedure and pronation of the left forearm. The affected wrist had 91% motion compared with the contralateral wrist.

DIAGNOSIS

Radiography and computed tomography showed 28° dorsally angulated malunion of the distal radius and ulnar head subluxation with respect to the radius. Magnetic resonance imaging revealed disruption of the ulnar-side triangular fibrocartilage complex (TFCC) from the ulna fovea.

INTERVENTIONS

The patient desired surgery to address the painful click during full supination of her left wrist and the limitations in her activities of daily living. Corrective osteotomy of the distal radius and arthroscopic repair of the ulnar-side tear of the TFCC were performed. The TFCC was arthroscopically repaired to the ulnar fovea to stabilize the DRUJ.

OUTCOMES

At 1 year postoperatively, radiography showed complete union of the radius. The affected side had 97% wrist motion compared with the contralateral wrist and a full range of forearm rotation without pain or clicking. The grasp strength was 100% compared with the normal wrist.

LESSONS

Malunited distal radius fracture with concomitant TFCC injury can result in habitual volar dislocation of the ulnar head due to severely dorsally angulated malunion of the radius and avulsion of the ulnar-side TFCC from the ulna fovea. This condition required corrective osteotomy plus TFCC repair.

Readmissions After Distal Radius Fracture Open Reduction and Internal Fixation: An Analysis of 11,124 Patients

Purpose:

Distal radius fracture (DRF) open reduction and internal fixation (ORIF) is a common surgical procedure. This study assesses reasons and risk factors for readmission after DRF ORIF using the large sample size and follow-up of the American College of Surgeons National Surgical Quality Improvement Program database.

Methods:

Adult patients who underwent DRF ORIF were identified in the 2011 to 2016 National Surgical Quality Improvement Program database. Patient demographics, comorbidity status, hospital metrics, and 30-day perioperative outcomes were tabulated. Readmission, time to readmission, and reason for readmission were assessed. Reasons for readmission were categorized. Risk factors for readmission were assessed with multivariate analyses.

Results:

Of 11,124 patients who underwent DRF ORIF, 196 (1.76%) were readmitted within 30 days. Based on multivariate analysis, predictors of readmission (P < 0.05) were as follows: American Society of Anesthesiologist class > 3 (Odds ratio [OR] = 2.87), functionally dependent status (OR = 2.25), diabetes with insulin use (OR = 1.97), and staying in hospital after the index surgery (inpatient procedure, OR = 2.04). Readmissions occurred at approximately 14 days postoperatively. Of the recorded reasons for readmission after DRF ORIF, approximately one quarter were for surgical reasons, whereas over 75% of readmissions were for medical reasons unrelated to the surgery.

Conclusion:

This study found the rate of 30-day unplanned readmissions after DRF ORIF to be 1.76%. Demographic, comorbid, and perioperative factors predictive of readmission were defined. Most postoperative readmissions were for medical reasons unrelated to the surgical site and occurred at an average of approximately 2 weeks postoperatively. Multivariate analysis found that patients with increased American Society of Anesthesiologist class > 3, functional dependence, insulin-dependent diabetes, and those who underwent inpatient surgery for any reason were at a greater risk for readmission. Understanding these factors may aid in patient counseling and quality improvement initiatives, and this information should be used for risk stratification and risk adjustment of quality measures.

Distal radius fractures: an evidence-based approach to assessment and management

Distal radius fractures account for one in five bony injuries in both primary and secondary care. These are commonly the result of a fall on outstretched hands or high-energy trauma. On assessment, clinicians should determine the mechanism of injury, associated bony or soft tissue injuries, and neurovascular symptoms. Investigations should always include radiographs to evaluate for intra-articular involvement and fracture displacement. Owing to the heterogeneous injury patterns and patient profiles, the preferred management should consider the severity of the fracture, desired functional outcome and patient comorbidities. Non-operative management in select patients can give good results, especially in older adults. Immobilisation with or without reduction forms the mainstay of non-operative treatment. Surgical management options include closed reduction and application of a cast, percutaneous K-wires, open reduction and internal fixation with plates, or external fixation. Patients should be encouraged to mobilise as soon as it is safe to do so, to prevent stiffness. Median nerve compression is the most common complication followed by tendon rupture, arthrosis and malunion. This article outlines the British Orthopaedic Association Standards for Trauma and Orthopaedics for the management of distal radius fractures.

Evaluation of Flexor Pollicis Longus Tendon Rupture after Treatment of Distal Radius Fracture with the Volar Plate

Background  The aim of this study is to evaluate the frequency of flexor pollicis longus (FPL) tendon rupture and factors leading to this rupture during the follow-up of patients who underwent volar plate fixation because of distal radius fracture. Patients and Methods  A total of 109 distal radius fractures of 102 patients treated with volar plate fixation and periodically followed up for at least 1 year between January 2013 and May 2018 were evaluated. Fractures were categorized according to the AO Foundation/Orthopaedic Trauma Association (AO/OTA) Fracture-Dislocation Classification and Soong's grading was used for classifying volar plate position. All patients operated were inquired retrospectively in terms of flexor tendon rupture. Results  Gender distribution revealed 45 females and 57 males. Mean age was 47.9 (range: 17-88) years. Mean period of follow-up was 27 months. Distribution of fractures in accordance with the AO/OTA distal radius classification was 6, 8, 7, 12, 24, 33, 11, and 8 patients with types A2, A3, B1, B2, B3, C1, C2, and C3, respectively. When volar plate positions were analyzed with Soong's classification, it revealed that 79 (72.4%), 23 (21.1%), and 7 (6.5%) plates were grade 0, 1, and 2, respectively. In total, evaluating the three patients with FPL rupture, it revealed that the volar plate was positioned distally during fixation because the fracture line had advanced to the distal of the watershed line, the distal portion of the plate had lost complete connection with the bone, and at this portion, it was observed that the pronator quadratus muscle was not covering the plate entirely (Soong's classification grade 2). Patients did not have additional flexor tendon injury. Conclusion  FPL tendon rupture is a rare but serious complication of volar plate fixation performed for distal radius fractures. We believe that appropriate choice of implant and careful surgical technique, along with the close follow-up of patients, with Soong's classification grade-2 volar positions would help in preventing this complication. Level of Evidence  This is a Level 3a, differential diagnosis/symptom prevalence study.

Intrarater and Interrater Reliability of the Soong Classification for Distal Radius Volar Locking Plate Placement

Background: The purpose of this study was to analyze the intrarater and interrater reliability of the Soong classification for volar locking plate placement on a randomly selected, consecutive series of radiographs. Our hypothesis was that the classification would be reliable. Methods: Six physicians of differing levels of training (orthopedic surgery intern to fellowship-trained upper extremity staff) were asked to review 40 radiographs in a random order on 2 separate occasions, 4 weeks apart. All observers graded each image (0, 1, or 2) based on the corresponding Soong grade. A weighted κ was used to determine the intrarater agreement. The interrater agreement was determined using an intraclass coefficient: Results: The intrarater reliability using a weighted κ ranged from 0.229 (95% confidence interval [CI]: 0.048-0.411) to 0.946 (95% CI: 0.840-1.051). The interrater intraclass coefficient for Randomization 1 was 0.944 (95% 0.912-0.967) and Randomization 2 was 0.877 (95% CI: 0.797-0.930). Conclusion: The Soong classification is a reliable tool, both interrater and intrarater, for assessing distal radius volar locking plate placement. The classification system remained reliable despite a randomly selected, consecutive series of images and physician observers of varying levels of training.

A randomized controlled trial on Aspirin and complex regional pain syndrome after radius fractures

Complex regional pain syndrome (CRPS) is often diagnosed in patients who are recovered with surgery or injury. CRPS is usually diagnosed in patients recovering from distal radius fractures. The aim of study was the effects of aspirin in prevention of the complex regional pain syndrome (CRPS) following a fracture of distal radius. In a double-blind, randomized controlled trial, 91 patients with unilateral extra-articular distal radius fractures were randomly allocated to receive either placebo (PLA) or 500 mg of aspirin (ASA) daily for 7 days. The effect of aspirin on the occurrence of CRPS was evaluated. The patients were assessed clinically and radiographically in the second, fourth and twelfth weeks by a physician who was unaware of the treatment allocation. Ninety-one patients (ASA, n=44; PLA, n=47) were enrolled in the study. The prevalence of CRPS in all patients was 16.5%. The prevalence of CRPS in the aspirin group was lower (13.6%) than the placebo group (19.1%), but this difference was not statistically significant. The only significant difference was the lower rate of regional osteoporosis seen in the radiographs of aspirin group. Mean age was significantly higher in the patients with CRPS. Also, comminuted distal radius fractures (A3-type) were significantly more common in the patients with CRPS. Administration of aspirin in patients with a distal radius fracture was associated with a lower incidence of CRPS, but, not statistically significant. Further investigations needs to be done with a larger sample size, longer follow-up period and multi-center design.

Identification of a novel three-column classification for double-column die-punch fractures of the distal radius

The present study aimed to classify double-column die-punch fractures of the distal radius according to imaging data, and to evaluate their clinical features. A retrospective analysis of imaging data derived from 498 patients diagnosed with a double-column die-punch fracture of the distal radius was performed. The fractures were divided into those with middle-column avulsion with fracture of the radial-column articular surface (type I), those with middle-column collapse with fracture of the radial-column articular surface (type II), those with middle-column collapse with fracture of epiphysis of the radial column (type III) or mixed-type fractures (type IV). The intra- and inter-observer consistency between assessors was analyzed with kappa statistics. The patients with double-column die-punch fractures of the distal radius were followed up. There were 21 cases of type I fracture, 135 cases of type II fracture, 130 cases of type III fracture and 212 cases of type IV fracture. The intra-observer kappa coefficient ranged from 0.810–0.861, whereas the inter-observer kappa coefficient range was 0.830–0.876, with high consistency. Following 13 months of follow-up, the patients were assessed for functional recovery of the wrist and hand using the Gartland-Werley scoring system. The analysis indicated that in 95.78% of the patients, wrist function was rated as excellent or good (n=477), while in 4.22% of patients it was rated as fair (n=21), mainly due to the development of post-traumatic arthritis of the wrist following inappropriate therapy. All of the cases were type IV and type III fractures. These data demonstrated the application of a novel classification system named the Three-Column Classification, used to classify double-column die-punch fractures of the distal radius. This method reflected the mechanisms and severity of the fractures, conforming to the principle of AO fracture classification. Furthermore, it exhibited high consistency and may provide reference values for clinical diagnosis, treatment and prognostic evaluation.

Outcomes and Complications in the Management of Distal Radial Fractures in the Elderly

BACKGROUND

The purpose of the present study was to identify trends in management and to compare the outcomes and complications following nonoperative and operative management (including external fixation, closed reduction and percutaneous pinning, and open reduction and internal fixation) for distal radial fractures in patients ≥65 years of age.

METHODS

We performed a retrospective analysis, with use of the OptumLabs Data Warehouse database, of patients ≥65 years of age who had been managed for a distal radial fracture between 2009 and 2014 (as indicated by diagnosis codes according to the International Classification of Diseases, Ninth Revision, Clinical Modification). Ninety-day and 1-year complication rates per 1,000 fractures were analyzed overall and by treatment modality.

RESULTS

Thirteen thousand, seven hundred and thirteen distal radial fractures were analyzed. The overall 90-day complication rate was 36.5 per 1,000 fractures, and the 1-year upper-extremity-specific complication rate was 236.2 and 307.5 per 1,000 fractures for nonoperative and operative management, respectively. Overall, post-injury stiffness was the most common 1-year upper-extremity-specific complication (incidence, 11.5%). There was no significant difference between operative and nonoperative management in terms of 90-day complication rates. However, operative management had a higher 1-year complication rate than nonoperative management (307.5 versus 236.2 per 1,000 fractures). Overall, the 5 most common upper-extremity-specific complications following operative treatment of distal radial fracture were stiffness (16.0%), chronic regional pain syndrome (9.9%), median neuropathy (8.0%), implant-related complications (3.8%), and tendon-related complications (2.8%). Stiffness was significantly more frequent following operative management (16.0% versus 9.8%; p < 0.01).

CONCLUSIONS

Operative management of a distal radial fracture should be carefully considered when discussing treatment options with patients ≥65 years of age.

Radial Plate Fixation of Distal Radius Fracture

Background: A radial incision with radial plate fixation for distal radius fracture has historically been avoided due to its risk to the superficial branch of the radial nerve (SBRN). With careful technique, it is possible to avoid injury to the SBRN, thereby minimizing the soft tissue injury associated with other approaches. We compare subjective and objective functional outcomes of radial plate fixation surgeries that we performed with those of dorsal and volar plate fixation in current literature. Methods: Patients at a single center who underwent radial plate fixation for an AO type A or AO type B distal radius fracture between December 2006 and December 2014 were enrolled in the study. Postoperative grip strength and 3-digit pinch strength were measured systematically in the injured and uninjured wrists. Patients also completed a Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) questionnaire to assess subjective outcomes. Results: Thirty-six patients met our inclusion criteria and had available medical records. Postoperative grip strength in the injured wrist was significantly lowered-68% compared with the uninjured wrist. After subgroup analysis of dominant and nondominant wrist injuries, there was no significant difference in grip strength between injured and uninjured wrists. There was no significant decrease in postoperative 3-digit pinch strength in the injured wrist-89% compared with the uninjured wrist. The mean QuickDASH score for our study participants was 20.9. Conclusions: Radial plate fixation is an effective approach for distal radius fractures. Objective and subjective outcomes are noninferior to those of a dorsal or volar approach.

Combined radius addition osteotomy and ulnar shortening to correct extra-articular distal radius fracture malunion with severe radial deviation and ulnar plus

Malunion can occur in 11 to 28% of Distal Radius Fractures and can result in radius shortening and ulnar plus with wrist deviation, pain and disability. We aimed to report particular cases of extra-articular distal radius fracture malunion with severe radial deviation and ulnar plus treated by corrective osteotomy of distal radius with bone graft associated to ulnar procedure. One of these patients was firstly operated with ulna subtraction osteotomy synthesized with plate and in a second stage with distal radius corrective addition osteotomy with homologous bone graft, plate and external fixator. Two other cases were treated in a single-step by radius addition osteotomy and caput ulnae Darrach resection. These three patients were followed-up from 2 to 12 years, successfully observing the maintenance of anatomical correction and recovery of ROM and strength with good pain relief and return to daily activities. After Darrach procedure external-fixation wasn't needed and pronation-supination was better. Darrach procedure can solve ulna plus and improve ROM in pronation-supination with a quicker healing, avoiding the risk of ulnar non-union. Darrach's procedure associated to addition corrective osteotomy of distal radius can be a valid treatment for distal radius severe malunion, in patients with low-moderate functional demand. In conclusion, the surgeon should choose the right corrective treatment after the complete evaluation of the patient and his functional needs.
