Risk factors for calcaneal fracture combined with vertebral fracture / 中华创伤骨科杂志

Objective:To analysis the risk factors for calcaneal fracture combined with vertebral fracture.Methods:A retrospective study was performed of the 745 calcaneal fractures which had been surgically treated from May, 2005 to September, 2020 in Nanjing Drum Tower Hospital Affiliated to Medical School, Nanjing University. There were 651 males and 94 females, aged from 11 to 89 years (mean, 43.8 years). The incidence of calcaneal fracture combined with vertebral fracture was recorded. The risk factors were screened out by univariate analysis from gender, age, body mass index, unilateral or bilateral calcaneal fractures, injury severity score (ISS), cause of injury, fall height, classifications of calcaneal and number of vertebral fracture; binary logistic regression analysis was used to determine independent risk factors from the rtsk factors with P<0.05. Results:Vertebral fracture occurred in 70 of the 745 patients with calcaneal fracture (9.40%). Univariate analysis showed significant differences in gender, body mass index, unilateral or bilateral calcaneal fractures, ISS and fall height between patients with simple calcaneal fracture and patients with calcaneal fracture combined with vertebral fracture ( P<0.05); Binary logistic regression analysis showed that gender ( OR=0.225, 95% CI:0.095~0.532, P=0.001), unilateral or bilateral calcaneal fractures ( OR=3.582, 95% CI:1.705~7.526, P=0.001), ISS ( OR=5.229, 95% CI:1.605~17.035, P=0.006), and fall height ( OR=49.820, 95% CI:23.068~107.597, P<0.001) were the independent risk factors for calcaneal fracture combined with vertebral fracture. Conclusion:A more likely combined vertebral fracture should be taken into consideration in male patient with bilateral calcaneal fractures, a falling height > 3 m, or a high ISS.

Progress in imaging research on the diagnosis of chronic osteomyelitis / 中华创伤骨科杂志

The imaging techniques have been widely used in the diagnosis of chronic osteomyelitis,including plain radiography,magnetic resonance imaging,computed tomography and radionuclide imaging.Plain radiography is useful in the early detection of suspected osteomyelitis,but its sensitivity is low.Due to its high resolution and sensitivity,MRI has been the most widely used but its specificity is relatively poor.CT is mainly recommended for diagnosis of chronic osteomyelitis in complicated anatomic regions.Radionuclide imaging will have prospects of broad application due to its diverse radiotracers and high sensitivity.This paper reviewed the research of imaging modalities in diagnosis of chronic osteomyelitis.
