title: Outcome of percutaneous sacroiliac joint fixation with porous plasma-coated triangular titanium implants: an independent review.
abstract: METHODS
  Independent retrospective review of a single surgeon's experience with a new technique of SI fixation.
  
  
  OBJECTIVE
  Examine results of percutaneous fixation of the SI joint with porous coated triangular titanium implants.
  
  
  BACKGROUND
  Diagnosis and treatment of a dysfunctional sacroiliac joint is challenging as well as controversial. Recently, percutaneous stabilization techniques have been implemented for fixation. There is minimal literature published on this technique.
  
  
  METHODS
  Charts, radiographs, and CT scans of 31 patients operated on by a single surgeon were de-identified and randomized and then reviewed by investigators not involved with the care of the patients. Reviewers had no relationship with the implant manufacturer at the time of the review.
  
  
  METHODS
  intraoperative and postoperative complication, EBL, hospital stays, postoperative image location and number of lucent implants, ingrowth into implants, and bone across SI joint.
  
  
  RESULTS
  27 patients expressed satisfaction, 4 patients did not. Pain relief was noted to be Complete (16 patients), Excellent (5 patients), Good (9 patients), and Fair (1 patients). Four patients had postoperative complications. These were infected hematoma (2), L5 nerve root irritation (1), and L5-S1 discitis (1). One patient required revision. On 6 month postop CT scan, 18/19 patients had radiographic evidence of bone ingrowth and bone into or across the SI joint was evident in 8/19 patients. Lucency was noted around at least one implant in 5/19 patients.
  
  
  CONCLUSIONS
  Results are promising for the use of this novel implant for a carefully selected group of patients with disabling SI dysfunction.
