Dual-channel minimally invasive percutaneous cerclage for femoral shaft and metaphysis fractures during the internal fixation with intramedullary nails: case reports and technical description.

When treating femoral fractures with closed reduction intramedullary nail fixation, excessive residual displacement of the fracture end can affect the fixation effect and prolong the healing time, which is difficult to manage intraoperatively. This article introduces a simple steel wire cerclage fixation technique, which is percutaneous and can control the incision within 1 cm without excessive reliance on specially designed surgical instruments. It is suitable for the reduction and fixation of oblique femoral metaphysis fractures and butterfly-shaped femoral shaft fracture blocks.

Evaluation of the effectiveness of the femoro-sacral posterior angle system for measuring spino-pelvic morphology in high-dysplastic developmental spondylolisthesis.

Objective: The Femoro-Sacral Posterior Angle (FSPA) system and the pelvic incidence (PI) system are utilized for measuring sagittal spino-pelvic morphology in patients with high-dysplastic developmental spondylolisthesis (HDDS). This study aimed to analyze the accuracy and stability of these two systems.

Methods: A retrospective analysis was conducted on 45 patients diagnosed with HDDS who underwent surgical treatment at our hospital (HDDS group), along with 45 patients without spondylolisthesis (normal group).

[Imaging analysis of ossification of ligamentum flavum associated with dural adhesions].

Objective: To summarize the characteristic imaging signs of ossification of the ligamentum flavum (OLF) associated with dural adhesions by analyzing retrospectively the imaging signs of OLF associated with dural adhesions.

Methods: A retrospective analysis was made on clinical data of 85 patients undergoing OLF surgery between January 2010 and September 2012. The patients were assigned into the study group and the control group according to the preoperative imaging signs.
