Post-Operative Infections in Spine Procedures: A Brief Review

Background and Aim: Surgical site infection is an important complication after spinal surgery. Prevention and treatment of this complication requires more and reliable information. In this article, we investigated the epidemiology, pathogenesis, diagnosis and treatment of post-operative infection in spine procedures by reviewing previous related studies. Methods and Materials/Patients: In this...

Operative management of unstable thoracolumbar burst fractures.

Operative management of unstable burst vertebral fractures is challenging and debatable. This study of such cases was conducted at the Aga Khan Hospital, Karachi from January 1998 to April 2003. All surgically managed spine injuries were reviewed from case notes and operative records. Clinical outcome was assessed by Hanover spine score and correction of kyphosis was measured for radiological a...

Lateral release for chondromalacia patellae.

A series of7S patients with established chondromalacia patellae is presented. All had a lateral release procedure carried out after failure of conservative treatment. The results are discussed in relation to the findings at operation. In the early stages of chondromalacia, release of the lateral retmaculum was successful in relieving the symptoms for a year or more; review at three years showed...

Gain-scheduling Procedures for Unstable Controllers: A Behavioral Approach

A behavioral approach to the design of gain-scheduled controllers is presented. Plant models are considered to be black-box models obtained at nitely many operating points, and it is assumed that no analytical or empirical relations are known between physical parameters and the plant models. In this situation, it is suggested to interpolate in intermediate operating points, simply by interpolat...
