The role of mesh technology with tumor prosthesis reconstruction to reconstruct the extensor mechanism of knee joint after resection of proximal tibial tumors.

Purpose: The aim of this study was to evaluate the role of mesh technique in the reconstruction of the extensor mechanism after resection of proximal tibial tumors.

Methods: We retrospectively analyzed the cases of 14 patients who were diagnosed with proximal tibial tumors at our center and reconstructed with tumor prosthesis, gastrocnemius muscle, and mesh between 2012 and 2017. The treatment strategies for patellar tendon reconstruction primarily involve gastrocnemius reconstruction to cover the tumor prosthesis and mesh reconstruction for the patellar ligament.

Significance of circulating tumor cells in osteosarcoma patients treated by neoadjuvant chemotherapy and surgery.

Purpose: By examining and identifying circulating tumor cell (CTC) counts and subtypes of peripheral blood in osteosarcoma patients, we evaluated the relationship between CTCs and characteristics of osteosarcoma patients, as well as CTC changes after neoadjuvant chemotherapy and surgery.

Methods: CanPatrol™ CTC technology was used to detect CTCs in peripheral blood before and after treatment in 32 osteosarcoma patients. Peripheral blood samples from 10 healthy volunteers were included as controls and examined for the presence of CTCs.

[Treatment of children with femoral subtrochanteric fracture with advanced elastic intramedullary nail technology].

Objective: To explore curative effects of advanced elastic intramedullary nail technology in treating children with femoral subtrochanteric fracture.

Methods: Form March 2009 to December 2010, 16 children with femoral subtrochanteric fracture were treated with advanced elastic intramedullary nail technology. There were 12 males and 4 females ranging in age from 7 to 15 years old with a mean of 9.
