Wrist Fractures and Osteoporosis

Evaluation of using grip strength and hand muscle cross-sectional area to predict secondary fractures post distal radius fracture

Grip strength measurement, as a surrogate of sarcopenia diagnosis, effectively predicts secondary fracture risk in distal radius fracture patients. This simple tool enhances clinical practice by identifying high-risk patients for targeted interventions, potentially preventing or reversing functional decline and recurrent fractures.

PURPOSE

To evaluate grip strength and hand muscle cross-sectional area as predictors of secondary fracture risk in patients with a history of distal radius fracture (DRF), serving as surrogates of the diagnosis of sarcopenia.

METHODS

A retrospective cohort study of 745 DRF patients was analyzed with their grip strength data using Cox proportional hazards regression, receiver operating characteristic analysis, and Kaplan-Meier analysis to predict secondary fracture risk over an average of 12 years. Hand muscle cross-sectional area was similarly analyzed.

RESULTS

Patients with a history of DRF were predicted to have a 4.1% higher likelihood of experiencing a secondary fracture per kilogram reduction in their grip strength (p < 0.008), independent of age and sex. Patients were categorized as high-risk (≤ 16 kg), moderate-risk (17-24 kg), or low-risk (≥ 25 kg) (p < 0.001). High-risk patients showed a 2.2-fold (95% CI = 1.55-3.17) higher recurrent fracture risk compared to low-risk patients. Cumulative secondary fracture probabilities of the high-risk group patients at 5, 10, and 15 years were estimated to be 16%, 30%, and 54%, respectively.

CONCLUSIONS

Grip strength measurement, as a surrogate of sarcopenia diagnosis, effectively predicts secondary fracture risk in patients with DRF. This simple tool could improve clinical practice by identifying high-risk patients for targeted interventions to prevent recurrent fractures or even reverse functional decline.

Rehabilitative good clinical practice in the treatment of osteoporosis: a comprehensive review of clinical evidences

PURPOSE

Clinical practice guidelines (CPGs) are essential for guiding rehabilitation interventions. However, CPGs specifically addressing rehabilitation for osteoporosis patients remain scarce in the literature. This review aims to present, compare, and summarize recent guidelines and evidence, highlighting best practices in osteoporosis rehabilitation management.

MATERIALS AND METHODS

A total of 19 guidelines were identified following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Three independent appraisers assessed the quality of each CPG using the Appraisal of Guidelines for Research and Evaluation version II (AGREE II) instrument. Standardized domain and overall quality scores were calculated, and intraclass correlation coefficients (ICCs) were used to assess the level of agreement among the appraisers.

RESULTS

Agreement among appraisers for AGREE II scores ranged from moderate to very good (ICC = 0.60 to 0.90). The quality of the included CPGs varied significantly, with AGREE sub-scores ranging from 48.25% to 75.73%. The Level of Evidence (LoE) and Grade of Recommendation (GoR) differed across the guidelines included in this review. Information on exercise types, intensity, frequency, duration, and contraindications were inconsistent among CPGs.

CONCLUSIONS

Recommendations regarding exercise parameters were often vague and inconsistent between CPGs, necessitating critical evaluation by healthcare providers when making clinical decisions.

Incidence and predictors of dorsal comminution in older adults with low-energy distal radius fracture

PURPOSE

To identify the incidence of dorsal comminution using computed tomography (CT) images and identify predictors of this phenomenon in older adults with low-energy distal radius fractures (DRFs).

METHODS

A total of 150 patients aged > 50 years with fall-induced dorsally angulated DRFs were enrolled in this study. Patients were divided into two groups based on the presence of dorsal comminution, defined as a metaphyseal void of greater than one-third of the maximum posterior to anterior depth of the bone on at least three cuts in the sagittal plane on post-reduction CT images. Data on participants' basic demographics, including age, sex, body mass index (BMI), and AO classification of DRFs, were collected. Bone mineral density (BMD) was assessed using T-scores of the femoral neck, and cortical thickness of the distal radius was determined from plain post-reduction radiographs. Radiological parameters and combined ulnar fractures were measured on plain pre-reduction radiographs.

RESULTS

Among study participants, 91 (61%) had dorsal comminution, whereas 59 (39%) had no dorsal comminution on CT images. Both patient groups were compared based on presence of dorsal comminution, and showed no significant differences in age, sex, BMI, BMD, or cortical thickness on radiographs. However, all radiological parameters were better in the no dorsal comminution group than in the dorsal comminution group, and the proportion of patients with combined ulnar fractures was higher in the dorsal comminution group. In the multivariate analysis, the presence of combined ulnar fractures was the only significant predictor of dorsal comminution (p = 0.029, odds ratio = 2.267, 95% confidence interval: 1.085-4.736).

CONCLUSION

The incidence of dorsal comminution is relatively high in patients with low-energy DRFs aged > 50 years. In particular, the presence of combined ulnar fractures is closely associated with dorsal comminution of DRFs. Thus, surgeons should exercise caution when evaluating this phenomenon.

Distal radius fractures and distal ulna fractures among adults in a southern China county during the 11-year-period 2010 to 2020

Most distal radius fractures are associated with distal ulnar fractures. However, there is still a lack of consensus on the incidence of different types of distal ulnar fractures among adults in China. Therefore, we analyzed the incidence of distal radial fractures with and without associated distal ulnar fractures among adults in a southern China county from 2010 to 2020. Registry data of 2333 patients (2351 sides) with a distal radius fracture from 2010 to 2020 underwent evaluation, encompassing parameters such as age, sex, distal radius fracture classification, fracture side, and distal ulnar fracture classification. Distal radial fractures were classified according to the AO/OTA classification. Distal ulnar fractures were examined using the Q-modifier classification. 1719 females (73.68%) and 614 males (26.32%) were included in the study. Compared to men, the incidence of distal radial fractures accompanying distal ulnar fractures in women was approximately 2.8 times higher. Additionally, 49.81% of distal radius fractures were associated with fractures of the distal ulna, while 46.44% were associated with fractures of the ulnar styloid. The most common fracture type was that of the ulnar styloid Q1 (93.73%). The mean age of female patients was 61.71 ± 12.13, while male patients had an average age of 50.63 ± 14.86. The Q1 type was the most common type of distal ulnar fracture. We also found that more females (age range: 50 years or older) had type C distal radius fractures compared to males. However, type B fractures were observed more frequently in males than in females (range: 18-49 years). Osteoporosis was believed to be the main cause of fractures in women aged >50 years old. Moreover, the peak incidence of radius fractures in males was lower than in females in different age groups.

Pickleball Primer: An Overview of Common Injuries, Treatment, and Optimization Strategies in Pickleball Athlete

Pickleball is one of the fastest growing sports in the United States with millions of players nationwide. It is a relatively appealing sport because of its ease of access, low impact, and highly social atmosphere, allowing players of all ages to participate. As the number of players continues its dramatic increase, player injuries are certain to increase in turn. There is little to no orthopaedic research on pickleball-related injuries and a paucity of data regarding treatment and prevention strategies. This summary was designed to familiarize orthopaedic surgeons with the basics of the sport and highlight potential pickleball-related injuries they may encounter in practice.

Surgical Considerations for Osteoporosis, Osteopenia, and Vitamin D Deficiency in Upper Extremity Surgery

Fragility fractures as a result of osteoporosis, osteopenia, or vitamin D deficiency are some of the most common injuries encountered in orthopedics and require careful consideration when determining the appropriate management and treatment options. A thorough perioperative evaluation can identify causes of low bone mineral density allowing for initiation of appropriate therapy. Surgical treatment of these fractures can be difficult, and techniques should be employed to ensure stable fixation. It is important to understand the potential pitfalls associated with treatment of fragility fractures to prevent avoidable complications. Postoperative management is key to preventing future injuries in this unique patient population.

Decrease in incidence of distal radius fractures in Oslo, Norway

This study reported the incidence of validated adult distal radius fractures in Oslo, Norway, in 2019. The incidence has been reduced over the last 20 years. However, it is still high compared to other regions in Norway and some of the other Nordic countries.

PURPOSE

We aimed to report the incidence of distal radius fractures in Oslo in 2019 and compare it to the incidence rates in 1998/1999.

METHODS

Patients aged ≥ 20 years resident in Oslo sustaining a distal radius fracture in 2019 were identified by electronic diagnosis registers, patient protocols, and/or radiology registers. The diagnosis was verified using medical records and/or radiology descriptions. We used the same method as the previous study from Oslo, making the comparison over time more accurate. The age-adjusted incidence rates and the age-standardized incidence rate ratio (IRR) were calculated.

RESULTS

The absolute number of fractures decreased from 1490 in 1998/1999 to 1395 in 2019. The IRR for women and men in the age group ≥ 20 years in 2019 compared to 1998/1999 was 0.77 (95% CI 0.71-0.84) and 0.77 (95% CI 0.66-0.90), respectively. The IRR for women and men in the age group ≥ 50 years in 2019 compared to 1998/1999 was 0.78 (95% CI 0.71-0.86) and 0.78 (95% CI 0.63-0.97), respectively. For the population in Oslo with Asian background compared to Norwegian background in the age group ≥ 50 years, the IRR in 2019 was 0.57 (95% CI 0.40-0.80) for women and 0.77 (95% CI 0.44-1.37) for men.

CONCLUSIONS

The incidence of distal radius fractures in Oslo has decreased over the last 20 years. It is still, however, higher than in other areas of Norway and in some of the other Nordic countries.

Current Management and Volar Locking Plate Fixation with Bone Cement Augmentation for Elderly Distal Radius Fractures-An Updated Narrative Review

Distal radius fractures (DRFs) are the most common among all kinds of fractures with an increase in incidence due to the rapidly expanded size of the elderly population in the past decades. Both non-surgical and surgical treatments can be applied for this common injury. Nowadays, more and more elderly patients with DRFs undergo surgical treatments to restore pre-injury activity levels faster. However, optimal treatment for geriatric DRFs is still debated, and careful evaluation and selection of patients are warranted considering clinical and functional outcomes, and complications following surgical treatments. Furthermore, osteoporosis is a predominant factor in elderly DRFs mostly deriving from a low-energy trauma, so many treatment modalities are developed to enhance better bone healing. Among various options for bone augmentation, bone cement is one of the most widely used measures. Bone cement such as calcium phosphate theoretically improves fracture stability and healing, but whether the elderly patients with DRFs can significantly benefit from surgical fixation with bone cement augmentation (BCA) remains controversial. Hence, in the present review, the latest literature regarding current concepts of management and evidence about volar locking plate fixation (VLPF) with BCA for elderly DRFs was searched in MEDLINE, Embase, Cochrane Central Register of Controlled Trials, and Web of Science; out of >1000 articles, full texts of 48 and 6 articles were then examined and analyzed separately for management and VLPF with BCA for elderly DRFs. We aim to provide the readers with updates concerning the above issues.

Dual-Energy CT-based Opportunistic Volumetric Bone Mineral Density Assessment of the Distal Radius

Background In patients with distal radius fractures (DRFs), low bone mineral density (BMD) is associated with bone substitute use during surgery and bone nonunion, but BMD information is not regularly available. Purpose To evaluate the feasibility of dual-energy CT (DECT)-based BMD assessment from routine examinations in the distal radius and the relationship between the obtained BMD values, the occurrence of DRFs, bone nonunion, and use of surgical bone substitute. Materials and Methods Scans in patients who underwent routine dual-source DECT in the distal radius between January 2016 and December 2021 were retrospectively acquired. Phantomless BMD assessment was performed using the delineated trabecular bone of a nonfractured segment of the distal radius and both DECT image series. CT images and health records were examined to determine fracture severity, surgical management, and the occurrence of bone nonunion. Associations of BMD with the occurrence of DRFs, bone nonunion, and bone substitute use at surgical treatment were examined with generalized additive models and receiver operating characteristic analysis. Results This study included 263 patients (median age, 52 years; IQR, 36-64 years; 132 female patients), of whom 192 were diagnosed with fractures. Mean volumetric BMD was lower in patients who sustained a DRF (93.9 mg/cm3 vs 135.4 mg/cm3; P < .001), required bone substitutes (79.6 mg/cm3 vs 95.5 mg/cm3; P < .001), and developed bone nonunion (71.1 mg/cm3 vs 96.5 mg/cm3; P < .001). Receiver operating characteristic curve analysis identified these patients with an area under the curve of 0.71-0.91 (P < .001). Lower BMD increased the risk to sustain DRFs, develop bone nonunion, and receive bone substitutes at surgery (P < .001). Conclusion DECT-based BMD assessment at routine examinations is feasible and could help predict surgical bone substitute use and the occurrence of bone nonunion in patients with DRFs. © RSNA, 2023 Supplemental material is available for this article.

DFR-U-Net: Dual residual and feature fusion network for ulna and radius segmentation on dual-energy X-ray absorptiometry images

BACKGROUND

Ulna and radius segmentation of dual-energy X-ray absorptiometry (DXA) images is essential for measuring bone mineral density (BMD).

OBJECTIVE

To develop and test a novel deep learning network architecture for robust and efficient ulna and radius segmentation on DXA images.

METHODS

This study used two datasets including 360 cases. The first dataset included 300 cases that were randomly divided into five groups for five-fold cross-validation. The second dataset including 60 cases was used for independent testing. A deep learning network architecture with dual residual dilated convolution module and feature fusion block based on residual U-Net (DFR-U-Net) to enhance segmentation accuracy of ulna and radius regions on DXA images was developed. The Dice similarity coefficient (DSC), Jaccard, and Hausdorff distance (HD) were used to evaluate the segmentation performance. A one-tailed paired t-test was used to assert the statistical significance of our method and the other deep learning-based methods (P < 0.05 indicates a statistical significance).

RESULTS

The results demonstrated our method achieved the promising segmentation performance, with DSC of 98.56±0.40% and 98.86±0.25%, Jaccard of 97.14±0.75% and 97.73±0.48%, and HD of 6.41±11.67 pixels and 8.23±7.82 pixels for segmentation of ulna and radius, respectively. According to statistics data analysis results, our method yielded significantly higher performance than other deep learning-based methods.

CONCLUSIONS

The proposed DFR-U-Net achieved higher segmentation performance for ulna and radius on DXA images than the previous work and other deep learning approaches. This methodology has potential to be applied to ulna and radius segmentation to help doctors measure BMD more accurately in the future.

Distal Radius Fracture Treatment Outcomes in Patients With Ipsilateral Hemiplegia or Hemiparesis

BACKGROUND

Little information exists to guide decision-making with regard to distal radius fractures in the setting of ipsilateral hemiparesis or hemiplegia.

METHODS

Patients who sustained a distal radius fracture in the setting of ipsilateral hemiparesis or hemiplegia secondary to brain injury were evaluated. Investigated variables included perioperative pain, preinjury House functional classification score, length of immobilization, radiographic outcome measurements, and time to union.

RESULTS

There were 15 patients with distal radius fractures with a mean age of 65.9 years. The mean clinical and radiographic follow-up was 2.8 and 2.9 years, respectively. Wrists were placed into the nonoperative group (NOG, n = 10) and operative group (OG, n = 5). Pain significantly decreased at final follow-up for both groups. Baseline House functional classification scores averaged 1.3 and 1.6 for the NOG and OG, respectively, and were maintained at final follow-up. Length of immobilization for the NOG was 46 days and OG was 37 days, P = .15. Radiographic outcomes at final follow-up in the NOG and OG, respectively, were a mean radial height of 9.3 versus. 11.6 mm, radial inclination of 18.3° versus 22.3°, 4.2° dorsal tilt versus 5.3° volar tilt, and tear drop angle of 45.6° versus 44.5°. There were no significant differences in these measurements. Time to radiographic union averaged 58 days for the NOG and 67 days for the OG, P = .42. There were no revision surgeries.

CONCLUSIONS

Based on this small case series, patients with distal radius fracture and ipsilateral hemiparesis or hemiplegia may have similar clinical, functional, and radiographic outcomes, regardless of nonoperative or operative treatment.

Can ultrasound-guided infraclavicular block be an alternative option for forearm reduction in the emergency department? A prospective randomized study

Objective

Ultrasound-guided infraclavicular nerve block (IB) has become a well-established method in several outpatient procedures; however, its use in emergency departments (EDs) remains limited. The aim of this study was to compare procedural sedation and anlagesia (PSA) and IB in the pain management for patients who underwent forearm fracture reduction in the ED.

Methods

This prospective randomized study included 60 patients aged 18 to 65 years, who visited the ED with forearm fractures. They were randomly divided into two groups: Group PSA (n=30) and Group IB (n=30). The pain scores of patients were evaluated before and during the procedure with the visual analog scale. Complications and patient and operator satisfaction levels were recorded.

Results

There was no difference between the two groups in terms of demographic characteristics. The median (interquartile range) pain scores observed during the procedures were significantly higher in Group PSA than in Group IB (4 [4–6] vs. 2 [0–2], respectively; P<0.001). Patient and operator satisfaction levels were significantly higher in Group IB (P<0.001). Oxygen desaturation was statistically higher in Group PSA than in Group IB (40.00% vs. 3.33%, respectively; P=0.002).

Conclusion

IB was an effective alternative for reducing pain and increasing patient satisfaction in ED patients undergoing forearm fracture reduction.

Deep learning approach for automatic segmentation of ulna and radius in dual-energy X-ray imaging

BACKGROUND

Segmentation of the ulna and radius is a crucial step for the measurement of bone mineral density (BMD) in dual-energy X-ray imaging in patients suspected of having osteoporosis.

PURPOSE

This work aimed to propose a deep learning approach for the accurate automatic segmentation of the ulna and radius in dual-energy X-ray imaging.

METHODS AND MATERIALS

We developed a deep learning model with residual block (Resblock) for the segmentation of the ulna and radius. Three hundred and sixty subjects were included in the study, and five-fold cross-validation was used to evaluate the performance of the proposed network. The Dice coefficient and Jaccard index were calculated to evaluate the results of segmentation in this study.

RESULTS

The proposed network model had a better segmentation performance than the previous deep learning-based methods with respect to the automatic segmentation of the ulna and radius. The evaluation results suggested that the average Dice coefficients of the ulna and radius were 0.9835 and 0.9874, with average Jaccard indexes of 0.9680 and 0.9751, respectively.

CONCLUSION

The deep learning-based method developed in this study improved the segmentation performance of the ulna and radius in dual-energy X-ray imaging.

Supraclavicular block with Mepivacaine vs Ropivacaine, their impact on postoperative pain: a prospective randomised study

BACKGROUND

Supraclavicular block (SCB) with long-acting local anaesthetic is commonly used for surgical repair of distal radial fractures (DRF). Studies have shown a risk for rebound pain when the block fades. This randomised single-centre study aimed to compare pain and opioid consumption the first three days post-surgery between SCB-mepivacaine vs. SCB-ropivacaine, with general anaesthesia (GA) as control.

METHODS

Patients (n = 90) with ASA physical status 1-3 were prospectively randomised to receive; SCB with mepivacine 1%, 25-30 ml (n = 30), SCB with ropivacaine 0.5%, 25-30 ml (n = 30) or GA (n = 30) with propofol/fentanyl/sevoflurane. Study objectives compared postoperative pain with Numeric Rating Scale (NRS) and sum postoperative Opioid Equivalent Consumption (OEC) during the first 3 days post-surgery between study-groups.

RESULTS

The three groups showed significant differences in postoperative pain-profile. Mean NRS at 24 h was significantly lower for the SCB-mepivacaine group (p = 0.018). Further both median NRS and median OEC day 0 to 3 were significanly lower in the SCB-mepivacaine group as compared to the SCB-ropivacaine group during the first three days after surgery; pain NRS 1 (IQR 0.3-3.3) and 2.7 (IQR 1.3-4.2) (p = 0.017) and OEC 30 mg (IQR 10-80) and 85 mg (IQR 45-125) (p = 0.004), respectively. The GA-group was in between both in pain NRS and median sum OEC. Unplanned healthcare contacts were highest among SCB-ropivacaine patients (39.3%) vs. SCB-mepivacaine patients (0%) and GA-patients (3.4%).

CONCLUSIONS

The potential benefit of longer duration of analgesia, associated to a long-acting local anaesthetic agent, during the early postoperative course must be put in perspective of potential worse pain progression following block resolution.

Forearm bone mineral density and fracture incidence in postmenopausal women with osteoporosis: results from the ACTIVExtend phase 3 trial

Abaloparatide increased ultradistal radius bone mineral density (BMD) in the Abaloparatide Comparator Trial in Vertebral Endpoints (ACTIVE) trial. Over the subsequent 24 months in ACTIVExtend, ultradistal radius BMD gains were maintained with alendronate. Conversely, 1/3 radius BMD remained stable during ALN treatment in ACTIVExtend after decreasing during ACTIVE.

INTRODUCTION

Abaloparatide (ABL) increased femoral neck, total hip, and lumbar spine bone mineral density (BMD) in postmenopausal women with osteoporosis and decreased the risk of vertebral and nonvertebral fractures in ACTIVE. Effects on fracture risk and BMD were maintained subsequently with alendronate (ALN) in ACTIVExtend. In a prespecified subanalysis of ACTIVE, ABL also increased BMD at the ultradistal radius. Our objective was to determine the efficacy of ABL followed by ALN vs placebo (PBO) followed by ALN on forearm BMD and fracture risk over 43 months in ACTIVExtend.

METHODS

Ultradistal and 1/3 radius BMD (ACTIVE baseline to month 43) were measured (ABL/ALN, n = 213; PBO/ALN, n = 233). Wrist fracture rates were estimated for the ACTIVExtend intent-to-treat population (ABL/ALN, n = 558; PBO/ALN, n = 581) by Kaplan-Meier (KM) method.

RESULTS

At cumulative month 25, mean increase from ACTIVE baseline in ultradistal radius BMD was 1.1% (standard error, 0.49%) with ABL/ALN vs - 0.8% (0.43%) with PBO/ALN (P < 0.01). BMD increases with ABL were maintained with ALN through month 43 in ACTIVExtend. BMD decreases at the 1/3 radius in ACTIVE (similar with ABL and PBO) were maintained through 24 months of ALN treatment in ACTIVExtend. Wrist fractures over 43 months occurred in 15 women with ABL/ALN (KM estimate, 2.8%) and 20 with PBO/ALN (KM estimate, 3.6%) (HR = 0.77, 95% CI 0.39, 1.50; P = not significant).

CONCLUSION

Ultradistal radius BMD gains following treatment with ABL in ACTIVE were maintained over 24 months of ALN treatment in ACTIVExtend. Conversely, 1/3 radius BMD remained stable during ALN treatment in ACTIVExtend after decreasing during ACTIVE.

Differences in patient and injury characteristics between sports- and non-sports related distal radius fractures

INTRODUCTION

The incidence of distal radius fractures (DRFs) is increasing as the number of people in recreational or sporting activities rises, due to a combination of increased leisure time and greater public awareness of the health-related benefits of sports. Despite the increases in sports-related distal radius fractures (SR-DRFs), there are limited studies regarding the characteristics of treatment and recovery.

HYPOTHESIS

There are characteristics specific to SR-DRF treated with conservative or operative management.

MATERIAL AND METHODS

Retrospective review was carried out between January 2010 and December 2017. Overall, 1706 patients were included in the study analysis. Among them, 317 patients were injured during sports activity (18.6%) and 1389 were injured during non-sports activity (81.4%). Demographic data were compared between the two groups. The type of sports was investigated in SR-DRF. Also, we compared surgically treated DRF patients to describe differences in patient characteristics, fracture characteristics, and postoperative complications.

RESULTS

The mean age of patients with SR-DRFs was significantly younger (28 vs. 52 years). The proportion of men was also significantly higher in SR-DRF group compared to NSR-DRF group (62.8 vs. 33.8%). We identified 27 kinds of sports associated with DRFs and the 5 sports topping the list associated were soccer (22.7%), cycling (17.7%), snowboarding (11.0%), ice-skating (9.1%), and mountain hiking (9.1%). There was no difference in terms of the treatment method. However, SR-DRF group had higher proportion of AO/OTA type A fracture (32.6 vs. 13.7%), and NSR-DRF group had higher proportion of type C fracture (79.5 vs. 64.2%). Postoperative complications showed no significant differences, except higher implant removal rate in SR-DRF.

DISCUSSION

Patients with SR-DRF were significantly younger and had higher proportion of men. Proportion of AO/OTA type A was higher in SR-DRF group and proportion of AO/OTA type C was higher in NSR-DRF group. Proportion of surgical treatment was similar in two groups. Given the growing population participating in sports activity worldwide, SR-DRFs are predicted to increase and further study is required.

Bone Loss in Distal Radial Fractures Treated with A Composite Xenohybrid Bone Substitute: A Two Years Follow-Up Retrospective Study

(1) Background: Recently, surgical treatment of distal radius fractures has increased exponentially. Many locking plates' fixation systems have been developed allowing a more stable reduction and early mobilization. Sometimes, open reduction and fixation of distal radius fractures may leave a residual bone loss requiring grafting. This retrospective study reports clinical and radiologic outcomes of distal radius fractures treated with xenohybrid bone grafting in order to assess (i) the safety of the investigated bone graft; (ii) its radiological integration and biomechanical performances, and (iii) clinical outcomes of the patients; (2) Methods: We performed a retrospective study on a cohort of 19 patients. Preoperative X-ray and CT scan were performed. The mean clinical and radiographical follow-up was two years. Safety of the xenohybrid bone graft was constantly evaluated. Clinical results were assessed through the DASH score and Mayo wrist score; (3) Results: No adverse reactions, infections, and local or general complication were related to the use of xenohybrid bone graft. The radiolucency of the xenografts suggested progressive osteointegration. No evidence of bone graft resorption was detected. All the patients reached consolidation with good to excellent clinical results; and (4) Conclusions: Clinical and radiological data demonstrated that xenohybrid bone grafting promotes new bone formation and healing in osteopenic areas caused by fracture reduction.

Radiocarpal joint stiffness following surgical treatment for distal radius fractures: the incidence and associated factors

Background

Postoperative radiocarpal joint stiffness (RJS) is common in patients with distal radius fractures (DRFs). The purpose of this study was to record the incidence of RJS and to determine potential risk factors that may be associated with it.

Methods

We retrospectively included a series of patients who suffered from DRFs and underwent volar plate fixation. Patients’ basic data, radiographic data, and postoperative data were collected. The incidence of RJS during follow-up was recorded, and both univariate analyses and multivariate logistic regression were used to determine factors associated with it.

Results

A total of 119 patients were included in this study. After surgical procedures, there were 42 (35.3%) patients with RJS and 77 (64.7%) patients without. The incidence of RJS after surgical treatment is 35.3%. Multivariate analysis showed that intra-articular fracture (OR, 1.43; 95% CI, 1.13–1.81), pre-operative severe swelling (OR, 1.35; 95% CI, 1.05–1.74), post-operative unsatisfied volar tile (OR, 1.38; 95% CI, 1.01–1.89), and improper rehabilitation exercise (OR, 1.72; 95% CI, 1.18–2.51) were correlated with the incidence of RJS during follow-up.

Conclusions

Patients with intra-articular fracture, pre-operative severe swelling, post-operative unsatisfied volar tile, and improper rehabilitation exercise were factors associated with the incidence of wrist stiffness. Preoperative risk notification and postoperative precautions are necessary for relevant patients.

Sarcopenia in distal radius fractures: systematic review of the literature and current findings

INTRODUCTION

Sarcopenia is a clinical syndrome characterized by the reduction in muscle mass, strength and physical ability. Although proximal femur fractures are one of the major burdens affecting the ageing population, distal radius fractures are equally important for frequency, clinical and social consequences. The aim of this study is to evaluate the incidence of sarcopenia in distal radius fractures and clinical implications in functional recovery.

MATERIALS AND METHODS

Scopus and PubMed search was performed to find relationship between sarcopenia and distal radius fractures. Literature search was performed between 2009 and 2019 including clinical trials and clinical studies related to "sarcopenia and distal radius fracture" and "sarcopenia and wrist fracture". After identification, studies were screened and analysed through the Oxford Level of Evidence.

RESULTS

According to the inclusion and exclusion criteria, five articles were included. Four articles analysed the incidence of sarcopenia and its role as a risk factor in patients with distal radial fractures, while one article focused on sarcopenia and clinical results of surgical treatment of distal radius fractures. Incidence of sarcopenia in patients older than 50 years with distal radius fracture varied between 29.7% and 31.7%. Patients with distal radial fractures did not show a significant inferior muscle mass than control group in examined population. Functional results of surgery were significantly inferior in sarcopenic patients than control group (no sarcopenia).

CONCLUSIONS

About 30% of patients older than 50 years with distal radius fracture suffered by sarcopenia; sarcopenic patients surgically treated had worse clinical results than no sarcopenic patients. Further studies with larger samples are needed to confirm these preliminary results.

Consumption of Nopal Powder in Adult Women

Osteoporosis is a chronic disease in adult women caused by menopause and some other factors, which entails deficiency of calcium in diet. Natural products are the best source of nutriments to reduce the risk of chronic diseases. Nopal (Opuntia ficus-indica) is a plant characterized by its nutritional components and benefits to health. Its calcium content increases with maturation process that could be beneficial for consumers. Nopal powder (NP) was elaborated from nopal harvested within 16-24 weeks of maturation, and the nutritional content was determined. An experimental clinical trial was performed to evaluate the effect of NP. A total of 69 women between 40 and 60 years old participated in the study. During 24 weeks, experimental group (n = 56) consumed a daily dose of 5 g of NP and control group (n = 13) continue with habitual diet. Changes in bone mineral density (BMD), body mass index (BMI), body fat percentage and serum calcium were assessed. Between baseline and after 24 weeks of consumption, no significant changes were found in BMD P = .885 experimental group and P = .970 control group, BMI P = .865 experimental group and P = .984 control group, body fat P = .744 experimental group and P = .740 control group and serum calcium P = .282 experimental group and P = .959 control group. These results indicate that advanced maturation NP does not have influence in bone health, BMI, and body composition in adult women.
