Surgical site infections are not uncommon following spinal operations, and they can be associated with serious morbidity, mortality, increased resource utilization. The accurate identification of risk factors is essential to develop strategies prevent these potentially devastating infections. We conducted a case-control study determine independent for surgical infection orthopaedic operations.We performed retrospective patients who had an operation at university-affiliated tertiary-care...

Recent advances in spinal instrumentation have brought about a new emphasis on the three-dimensional deformity of scoliosis and especially restoration normal sagittal plane contours.

Forty-three have been followed ≥2 years are basis of this study. There three treatment groups: group I. no fusion (nine patients); II, transverse process autogenous iliac bone graft instrumentation (11 initial patients, one lost to follow-up a...

Perioperative myocardial infarction is the most common cause of morbidity and mortality in patients who have had noncardiac surgery, but its diagnosis can be difficult. The present study was designed to determine whether measurement serum levels cardiac troponin I, a highly sensitive specific marker for injury, would help establish infarction.

In Brief Study Design. A retrospective analysis, including prospectively collected patient outcomes data. Objective. To determine the rate of complications and in patients ≥60 years age who underwent major spinal deformity surgery requiring a minimum 5-level arthrodesis procedure. Summary Background Data. As population ages, an increasing number older are presenting with disorders that may require reconstructive procedures. Previous studies have reported complication rates as high 80% this...

In Brief Study Design. Retrospective case-control series. Objective. The purpose of this study is to determine whether perioperative complications alter subsequent clinical outcome measures in adult spinal deformity surgery. Summary Background Data. Increasingly, the benefit surgical intervention being evaluated based on patient reported outcomes and standardized health related quality life (HRQOL) measures. As improvement or deterioration HRQOL scores becomes a standard for evaluation...

Study Design. This was a prospective study of 24 adult patients with kyphosis or anterior column spinal defects treated fresh frozen allograft for and posterior instrumentation autogenous grafting.

Methods. Upright radiographs analyzed before surgery, immediately after at final follow-up examination...

In Brief Study Design. Retrospective radiographic outcomes analysis. Objective. We had 3 hypotheses: 1) a longer fusion; 2) more proximal instrumented vertebra, and 3) circumferential fusion versus posterior-only would increase the likelihood of adjacent segment disease (ASD).

Fixed sagittal imbalance (a syndrome in which the patient is only able to stand with weight-bearing line front of sacrum) has many etiologies. The most commonly reported technique for correction Smith-Petersen osteotomy.
