简要总结
Heterotopic ossification (HO) is a common complication after surgical repair of elbow trauma. Uric acid is the end-product of purine metabolism that has any physiological and pathogenic potential functions. However, the relationship of HO and uric acid has not been explored up to now. This study aimed to assess the relationship of HO and uric acid. The investigators retrospectively reviewed the demographics of participants who undergone the surgery for elbow trauma in our hospital between January 2012 and December 2018. One hundred participants included in our study. The participants were divided into two groups by the existing HO or not. The serum uric acid between both groups were compared by using the independent samples student T tests.
详细描述
The investigators retrospectively analyzed the demographics of these participants in our hospital who underwent the surgery after trauma of elbow joint between January 2012 and December 2018. All of the participants had a previous history of elbow joint fractures including distal humerus fracture or proximal ulna fracture or capitulum radii fracture or elbow fracture dislocation. According to X ray or CT scan, the participants were divided into two groups. One group the participants had not existed radiographic evidence of heterotopic ossification or formatted ectopic lamellar bone. And the other group is the participants with radiographic evidence of heterotopic ossification. And we recorded patient serum uric acid, sex and age, Body Mass Index (BMI), the situation of joint trauma and comorbid conditions including diabetes mellitus or impaired blood glucose, gout, metabolic syndrome, osteoporosis and various vitamin deficiency diseases. Moreover, the grades of heterotopic ossification were recorded for all patients according to Hastings and Graham Classification System for Heterotopic Ossification at the Elbow Joint.
