Medial Buttress Plate and Allograft Bone-Assisted Cannulated Screw Fixation for Unstable Femoral Neck Fracture with Posteromedial Comminution: A Retrospective Controlled Study.

Objective: To investigate the outcomes of open reduction and internal fixation combined with medial buttress plate (MBP) and allograft bone-assisted cannulated screw (CS) fixation for patients with unstable femoral neck fracture with comminuted posteromedial cortex.

Methods: In a retrospective study of patients operated on for unstable femoral neck fractures with comminuted posteromedial cortex from March 2016 to August 2020, the clinical and radiographic outcomes of 48 patients treated with CS + MBP were compared with the outcomes of 54 patients treated with CS only. All patients in the CS + MBP group were fixed by three CS and MBP (one-third tubular plates or reconstructive plates) with bone allografts.

Application of a medical image processing system in liver transplantation.

Background: At present, imaging is used not only to show the form of images, but also to make three-dimensional (3D) reconstructions and visual simulations based on original data to guide clinical surgery. This study aimed to assess the use of a medical image-processing system in liver transplantation surgery.

Methods: The data of abdominal 64-slice spiral CT scan were collected from 200 healthy volunteers and 37 liver cancer patients in terms of hepatic arterial phase, portal phase, and hepatic venous phase.

Digital medical technology based on 64-slice computed tomography in hepatic surgery.

Background: With the rapid development of computer technology, digital medicine has become a new direction in surgery. The application of digital medicine in hepatic surgery is still at the early stage and less reported in the literature. The aim of this study was to apply digital medical technology in the context of hepatic surgery.

[Study on the clinical application of abdominal medical image proceeding system in extended hepatectomy].

Objective: To study the applied value of abdominal medical image proceeding system (AMIPS) in extended hepatectomy.

Methods: Sixty-four-slice spiral computer tomography (CT) scan data of 32 cases treated from September 2007 to July 2009 (15 male, 17 female; mean age 52 years old) with liver tumor was collected, among which there were 9 cases with huge liver tumor. The data was imported into AMIPS for sequence segmenting and three-dimensional (3D) reconstruction.

Application of a visible simulation surgery technique in preoperation planning for intrahepatic calculi.

Background: The aim of this study was to evaluate a visible simulation surgery technique for choosing the best surgical plan in patients with intrahepatic calculi.

Methods: A medical image processing system was used to process computed tomography (CT) scanning data collected from four cases of intrahepatic calculi. Models of liver and bile ducts in standard template library format were processed by a free-form modeling system and reconstructed three-dimensionally.

[Study on the applied value of digital medical technology in diagnosis and treatment of the hepatolithiasis].

Objective: To study the value of digital medical technology in diagnosis and treatment of the hepatolithiasis.

Methods: 64-slice spiral computer tomography (CT) scan data of 14 cases (11 female, 3 male; median age, 48 years) with hepatolithiasis admitted from February to September 2008 were collected. The data were imported into medical image proceeding system (MIPS) for sequence segmenting and three-dimensional (3D) reconstruction.

[Study on the application of value of digital medical technology in the operation on primary liver cancer].

Objective: To study the clinical application of digital medical in the operation on primary liver cancer.

Methods: The patients (n=11) with primary hepatic carcinoma treated between February and July 2008, including 9 cases of hepatocellular carcinoma, 2 cases of cholangiocellular carcinoma, were scanned using 64 slices helicon computerized tomography (CT) and the datasets was collected. Segment and three-dimensional (3D) reconstruction of the CT image was carried out by the medical image processing system which was developed.

[Study on visualized virtual surgery of living-related donor liver transplantation].

Objective: To investigate the significance of three dimensional visualization and virtual surgery system in living related donor liver transplantation surgery.

Methods: Two patients suffered biliary calculi were scanned by 64 slice helical computer tomography (CT) on livers and the data were imported into medical image proceeding system (MIPS) for sequence. Man-made segmentation and true-up on the image from the data were carried out.

[Value of virtual surgery in arterial reconstruction in liver recipients with type II hepatic artery variation].

Objective: To investigate the value of virtual surgery in hepatic artery reconstruction in liver recipients with type II hepatic artery variation.

Methods: A patient with cholangiocellular carcinoma and a healthy individual were scanned using 64-slice spiral CT, and image segmentation and three-dimensional (3D) reconstruction were performed using an image processing system. The 3D models in STL format were then imported to the FreeForm Modeling System for smoothing and refinement.
