Morphological study of CT image of posterior pilon variant fracture and its possible clinical significance.

Objective: The incidence of posterior pilon variant fractures has been underestimated. The purpose was to study the characteristics of posteromedial (PM) and posterolateral (PL) fragments in CT imaging of posterior pilon variant fractures, and to provide help for clinical diagnosis and treatment.

Methods: CT imaging data of 109 cases of posterior pilon variant fractures in our hospital from January 2013 to December 2020 were retrospectively analyzed.

[Incidence and risk factors of early deep venous thrombosis after knee arthroscopy operation under conventional tourniquet].

Objective: To find out the incidence of early DVT in patients after knee arthroscopic surgery with routine use of tourniquet and discuss the associate risk factors.

Methods: Total 1 561 cases undertaken primary knee arthroscopic surgery was reviewed retrospectively from January 2013 to January 2017, including 651 males and 910 females with a mean age of (65.7±8.

[Clinical research on the efficiency of physical examinations used for diagnosis of subacromial impingement syndrome].

Objective: To evaluate the reliability and diagnosis accuracy of 5 special tests used for the diagnosis of subacromial impingement syndrome (SAIS).

Methods: A prospective blinded cohort study was taken,in which 105 patients with shoulder pain were reviewed. All the patients took 5 special syndrome tests including Neer syndrome, Hawkins-Kennedy syndrome, painful arc empty can test and external rotation resistance test, also underwent arthroscopic surgical examination.

[Minimally invasive pie-crusting technique combined with arthrolysis for the treatment of the stiff knee].

Objective: To study the effectiveness of pie-crusting technique in improving the stiff knee.

Methods: From February 2012 to December 2013, 13 patients with stiff knee were reviewed retrospectively. There were 6 males and 7 females, ranging in age from 39 to 70 years old (averaged, 55.

[Open reduction and internal fixation via a posterior approach for posterior fractures of tibial plateau].

Objective: To discuss the fracture patterns,operative procedures and clinical results of open reduction and internal fixation via a posterior approach to treat posterior fractures of tibial plateau.

Methods: From June 2008 to February 2011, 8 patients with posterior tibial plateau fractures treated with posterior approach, were reviewed retrospectively. There were 5 males and 3 females,with an average of 41.
