Delayed total hip arthroplasty after failed treatment of acetabular fractures: an 8- to 17-year follow-up study.

Background: Delayed total hip arthroplasty (THA) is a reliable procedure following failed treatment of acetabular fractures. The aim of the present study was to evaluate the influence of the type of fracture treatment and modern ceramic bearing on the clinical outcomes of delayed THA.

Methods: Between January 1997 and January 2008, 33 patients (33 hips) underwent cementless THA after failed acetabular fractures.

Synergistic effects of titania nanotubes and silicon to enhance the osteogenic activity.

In this study, titania nanotubes (TNTs) incorporating silicon (Si) were formed on Ti disks using anodization and electron beam evaporation (EBE) technology to improve the osteogenic activity. The amount of Si was exquisitely adjusted by controlling the duration of EBE to optimize the biofunctionality. As the Si was incorporated, the samples exhibited hydrophilic surfaces.

[Percutaneous vertebroplasty and open vertebroplasty for metastatic spinal tumor].

Objective: To explore the clinical application and therapeutic effect of percutaneous vertebroplasty(PVP) and open vertebroplasty for metastatic spinal tumor.

Methods: The clinical data of 126 patients with metastatic spinal tumor underwent surgery and obtained follow-up from January 2012 to March 2016 were retrospectively analyzed. These 126 cases were divided into two groups according to different operative methods.

Mid term results of total hip arthroplasty using polyethylene-ceramic composite (Sandwich) liner.

Background: Ceramic-on-ceramic (COC) couplings are an attractive alternative bearing surfaces that have been reported to eliminate or reduce problems related to polyethylene wear debris. However, the material in total hip arthroplasty (THA) remains one of the major concern regarding the risk of fracture. The present study aims at reporting the fracture rate of bearings in a series of COC THAs with the use of a sandwich liner and attempt to detect the relative risk factors, the possible cause and assess the clinical results.

Ceramic-on-ceramic bearings total hip arthroplasty in young patients.

Background: The results of ceramic-on-ceramic (CoC) total hip arthroplasty (THA) in younger patients were not univocal. This study aims to evaluate the results of CoC bearing THA in patients younger than 50 years.

Methods: A total of 90 younger patients performed CoC THAs during March 2003 and May 2008 were included in this study.

Tension band wiring through double-cannulated screws as a new internal fixation method for treatment of olecranon fractures: a randomized comparative study.

Objective: The aim of this study was to assess the therapeutic effects and complications of tension band wiring (TBW) through the use of double-cannulated screws versus conventional TBW in the treatment of olecranon fractures.

Methods: Eligible participants were randomly assigned to 2 groups to undergo different methods of fixation. The related indices and data of the 2 groups were collected for comparative analysis after an average follow-up of 32.

Is tumor length a prognostic indicator for esophageal squamous cell carcinoma? A single larger study among Chinese patients.

Objective: In esophageal cancer, depth of wall penetration, reflected by T classification, represents the most important prognostic variable. Our study aimed to investigate the impact of tumor length, measured as the longitudinal length, on the outcome of esophageal squamous cell carcinoma (ESCC) patients.

Methods: The survival data of 362 ESCC patients who underwent surgical resection as the primary treatment between 1999 and 2007 were collected retrospectively.

[Application of Ivor-Lewis esophagectomy in elderly patients with carcinoma in middle and lower esophagus].

Objective: To evaluate the safety of Ivor-Lewis procedure for middle and lower esophageal carcinoma in the elderly.

Methods: From June 2009 to June 2010, 232 cases aged over 60 years were diagnosed as esophageal carcinoma. These cases were randomly divided into two groups using table of random digits.

Expression of e-cadherin and beta-catenin in human esophageal squamous cell carcinoma: relationships with prognosis.

Aim: To elucidate the expression of E-cadherin and beta-catenin correlating with its clinical outcome in patients with esophageal squamous cell carcinoma (ESCC), by analyzing their interrelationship with clinicopathological variables and their effects on progress and prognosis.

Methods: Expression of E-cadherin and beta-catenin was determined by SP immunohistochemical technique in patients with ESCC consecutively, their correlation with clinical characteristics was evaluated and analyzed by multivariate analysis.

Results: The rate of expression of E-cadherin decreased to 66.
