The Role of Secondary Imaging Techniques for Assessing Bone Mineral Density in Elderly Ankle Fractures

A comparison of foot fractures relative to other fragility fractures: a review and analysis of the American Orthopaedic Association's Own the Bone Database

Evidence regarding the risk factors and characteristics of those with foot fragility fractures compared to non-foot fragility fractures is limited. Foot fragility fracture patients are more likely to be younger female with a higher BMI. A foot fragility fracture is strongly predictive of a subsequent foot fragility fracture.

PURPOSE

Osteoporosis can clinically result in fragility fractures. Evidence regarding the risk factors and characteristics of foot fragility fractures compared to non-foot fragility fractures is limited. The American Orthopaedic Association's Own the Bone (OTB) is a bone health initiative with a substantial dataset. The purpose of this study was to examine and compare characteristics of patients presenting with isolated foot fragility fracture to those with a non-foot fragility fracture.

METHODS

Between January 2009 and March of 2022, 58,001 fragility fractures occurred that were included in this cohort. A total of 750 patients had foot fragility fracture(s) and 57,251 patients had a non-foot fragility fracture that included shoulder, arm, elbow, forearm, wrist, spine, ribs, pelvis, hip, thigh, knee, tibia/fibula, and ankle. Demographics, fracture history, bone health factors, medication history, and medication use for each patient were reported in the OTB database. This data was utilized in our secondary cohort comparative analysis of characteristics and the risk of future fractures between foot fragility fracture and non-foot fragility fracture groups.

RESULTS

Foot fragility fracture patients have a significantly higher probability to be younger (66.9 years old), female (91.5%), and have a higher BMI (28.3 kg/m2) compared to non-foot fragility fracture (p < 0.0001) patients. Patients with a foot fragility fracture are nine times (OR = 9.119, CI = 7.44-11.18, p < 0.001) more likely to have had a prior foot fragility fracture. Young, female patients with a prior foot fragility fracture are at higher risk of a future foot fragility fracture, and this risk increased as BMI increased.

CONCLUSIONS

Foot fragility fracture patients are more likely to be female and younger compared to patients with a non-foot fragility fracture. A foot fragility fracture is a sentinel event considering that a prior foot fragility fracture is strongly predictive of a subsequent foot fragility fracture.

Effect of light walking combined with arthroscopic surgery on bone mineral density in patients with foot and ankle osteoarthritis

ObjectiveTo observe the effect of light walking combined with arthroscopic surgery on the efficacy and Bone Mineral Density (BMD) of patients with ankle arthritis. Methods 180 patients with ankle arthritis were retrospectively selected, who were divided into a control group (Group A) and an experimental group (Group B) according to treatment methods, with 90 patients in each group. Group A was treated with conventional open surgery and Group B was treated with light walking combined with arthroscopic surgery. The two groups were compared before and after treatment on scales such as the AOFAS ankle hindfoot score. Meanwhile, the patients' BMD and levels of inflammatory factors such as tumor cell necrosis factor-α (TNF-α) were compared before and after treatment. Results The Kofoed and AOFAS scale scores were higher for mild walking combined with arthroscopic surgery than for conventional treatment (P < 0.05), and their pain visual analogue VAS scores were lower than for conventional treatment (P < 0.05). In Group B, the postoperative BMD increase was significantly higher (P < 0.05). The R-value between PDGF bone growth factor and BMD was 0.957 and the R-value between VEGF growth factor and BMD was 0.903. The R-value between patient age and BMD was -0.936 and the R-value between patient BMI and BMD was -0.913. The treatment efficiency in Group B was 96.7 %. Conclusion The results prove that light walking combined with arthroscopic surgery is suitable for the surgical treatment of patients with ankle arthritis because it has a better therapeutic effect and makes patients' BMD level improved.

A Comparison of Ankle Fractures Relative to Other Fragility Fractures: A Review and Analysis of the American Orthopaedic Association's Own the Bone Database

BACKGROUND

Ankle fragility fractures (AFX) continue to increase in the elderly population. There is limited knowledge of AFX characteristics compared to nonankle fragility fractures (NAFX). The American Orthopaedic Association's Own the Bone (OTB) is a fragility fracture initiative. This robust data set was used to examine and compare characteristics of patients presenting with AFX to those with NAFX.

METHODS

The OTB database contained 72,617 fragility fractures between January 2009 and March of 2022 and were reviewed in our secondary cohort comparative analysis. After exclusions, AFX accounted for 3229 patients and 54,772 patients were in the NAFX cohort. Bivariate analysis and logistic regression compared the AFX and NAFX groups concerning demographics, bone health factors, medication use, and prior fragility fracture.

RESULTS

AFX patients were found to have a higher likelihood to be younger (67.6 years old), female (81.4%), non-Caucasian (11.7%) and have a higher BMI (30.6) compared to NAFX. Prior AFX predicted the risk of a future AFX. The probability of an AFX increased with increased age and BMI.

CONCLUSION

A prior AFX is independently predictive of subsequent AFX. Therefore, these fractures should be considered a sentinel event. These patients are more likely to have higher BMI, to be of female gender, non-Caucasian race, and are younger compared to patients with NAFX.

Quantitative Ultrasound and Bone Health in Elderly People, a Systematic Review

Reduced bone mineral density (BMD), osteoporosis, and their associated fractures are one of the main musculoskeletal disorders of the elderly. Quickness in diagnosis could prevent associated complications in these people. This study aimed to perform a systematic review (SR) to analyze and synthesize current research on whether a calcaneal quantitative ultrasound (QUS) can estimate BMD and predict fracture risk in elderly people compared to dual-energy x-ray absorptiometry (DXA), following the PRISMA guidelines. A search was conducted in the main open-access health science databases: PubMed and Web of Science (WOS). DXA is the gold standard for the diagnosis of osteoporosis. Despite controversial results, it can be concluded that the calcaneal QUS tool may be a promising method to evaluate BMD in elderly people, facilitating its prevention and diagnosis. However, further studies are needed to validate the use of calcaneal QUS.
