[Case-control study on poking closed reduction cannulated screw fixation and small incision reduction plate fixation for the treatment of calcaneal fractures].

Objective: To compare poking closed reduction cannulated screw fixation and small incision reduction plate fixation in treating calcaneal fractures.

Methods: Clinical data of 98 patients with calcaneal fractures were retrospectively analyzed from June 2015 and June 2018. According to fracture classification and treatment methods, the patients were divided into poking closed reduction cannulated screw fixation (group A) and small incision reduction plate fixation(group B).

[Clinical outcomes of total hip arthroplasty using Wagner SL revision stem in femoral intertrochanteric fractures for patients with old fracture or painful arthritis before injury].

Objective: To retrospectively study the clinical results of total hip arthroplasty(THA) using Wagner SL revision stem for patients with femoral intertrochanteric fracture.

Methods: From 2006 January to 2009 December, 29 consecutive patients with femoral intertrochanteric fractures were performed THA using Wagner SL revision stem and intertrochanteric reconstruction, including 18 males and 11 females with an average age of 49 years old ranging from 43 to 58. Among them, 8 cases were oboslete femoral intertrochanteric fractures and 21 cases were the intertrochanteric fractures with painful arthritis before injuries.

[MRI ainalysis of the pseudo-tears of the lateral meniscus of the knee and its clinical significance].

Objective: To determine the mechanism of pseudo-tears of the lateral meniscus caused by the transverse geniculate ligament (TL) and the miniscofemoral ligament(MFL) and to investigate a method to differentiate pseudo-tears from true tear of the lateral meniscus.

Methods: Form June 2012 to February 2014, MR examinations of 72 knees (44 left knees and 28 right knees) without tear of the lateral meniscus verified by arthroscopy were performed in the sagittal and coronal plane. There were 41 males and 31 females in the group, with an average age of 33.

[Diagnostic value of 3D-indirect magnetic resonance arthrography in detecting meniscal tears of the knees].

Objective: To explore the diagnostic value of 3D-indirectmagnetic resonance (MR) arthrography in detecting meniscustears of the knees.

Methods: Form January 2013 to January 2014, routine plain MR of the knees followed by the 3D-indirect MR arthrography was performed in 42 patients with suspected meniscal tears clinically. There were 31 males and 11 females, with an average age of 38.
