Neurologic Complications in Spinal Deformity Surgery
Evaluation of Neurologic Complications Associated With Surgical Correction of Adult Spinal Deformity: A Prospective, Observational, Multi-center Study
240 subjects with "high risk" adult spinal deformity requiring surgical correction will be enrolled in a prospective multi-center international study. "High risk" patients are defined by either their diagnoses and/or the type of surgical intervention as listed in the inclusion criteria. Neurologic complications in the form of new motor and sensory deficits will be monitored prospectively in all patients at hospital discharge, and at 6 weeks (± 2 weeks) six months (± 2 months) and 24 months(± 2 months) after the surgery. All new deficits will be adjudicated for relationship to the surgical intervention.
Regression analyses will be used to evaluate the association between patient demographics, co morbidities, treatment history, spinal deformity characteristics, surgical characteristics, non-neurologic complications and pre-surgical status to occurrence of a neurologic deficit after surgery.

Подробное описание
Although the incidence of complications in patients undergoing correction of their spinal deformity has been reported extensively, the majority of these studies were retrospective. There were only five studies, three from a single institution, with prospectively collected data that specifically identified complications. The largest series was from Buchowski et al who reported on 108 patients with fixed sagittal deformity undergoing Pedicle Subtraction Osteotomy (PSO) with a 14% over-all complication rate with motor weakness in 11 patients and neurogenic bladder in one patient, of which 3 were permanent. Yang reported on 35 patients undergoing PSOs with a 46% over-all complication rate and one transient nerve root motor deficit. Ahn in 2002 reported on 83 patients undergoing various osteotomies for sagittal imbalance and reported a 34% over-all complication rate with 3 permanent and 3 transient nerve root deficits.
Given this lack of information, there is a need to determine the true incidence of complications using a prospective multi-center design. There is a need to identify neurologic deficits in a more systematic fashion to include spinal cord, cauda equina and nerve root deficits as well as radiculopathies. The risk factors associated with the occurrence of a complication, especially a neurologic complication, also needs to be more fully elucidated. This is increasingly relevant, as newer surgical techniques allow for more aggressive correction of the spinal deformity that may put the spinal cord and nerve roots at increased risk. Valid data on the incidence and types of neurologic deficits is also needed in order to study newer drugs that are available that may mitigate this risk.
The primary objectives of this study are: (i) to establish the incidence of neurologic deficit in "high risk" adult patients undergoing correction of their spinal deformity of adult spinal deformity and (ii) to identify characteristics associated with increased risk of neurologic complications. Secondary objectives include (i) to determine the incidence of all complications related to surgical correction of "high risk" adult spinal deformity; (ii) to determine the short-term clinical outcomes in patients undergoing correction of their spinal deformity and (iii).to determine amount of radiographic and clinical correction of deformity
