For the past few years, incidence of tuberculotic disease inceased stablely, spinal tuberculosis, as the highest incidence of tuberculosis of bones and joints, has been the focus of the orthopedist study. With the development of recognization of spinal tuberculosis and spinal internal fixation technology, the treatment of spinal tuberculosis has been made a great progress, especially in surgical therapy, many new ways have been found in selection of surgical cases, preparation of surgery, surgical skills and surgical postprocessing. Now summarization is made in this paper.

In recent years,with the rapid development of minimally invasive spine surgery,lumbar disc herniation of minimally invasive treatment is an important progress.The operative injury is small,the duration is short and the effect is satisfactory.Correct recognition of microinvasive surgery,strictly grasp of its indication and perfect operative techniques are the keys to get good therapeutic efficacy.In this review,various methods of minimally invasive techniques and their clinical applications are summarized.

[Objective]To analyse the clinical effect of total knee resurface replacement treatment for advanced knee gouty arthritis. [Method]From March 2001 to July 2007,nine patients with advanced gouty knee arthritis(total 10 knees) were treated with total knee resurface replacement with posterior stability prosthesis in the author's research group.Among them,eight patients had unilateral knees and one had bilateral knees.Following-up data were successfully obtained.[Result]All the patients were followed up for at least one year.HSS Score system revealed that six knees were rated as excellent,two as good and two as fair.Either preoperative or follow-up HSS scores was analysed by T-test and their significant differences were observed(P
