Free-hand placement of iliac screws for spinopelvic fixation based on anatomical landmarks: technical note
BACKGROUND The placement of iliac screws is a biomechanically sound method for the stabilization of long multi-segment lumbar constructs. Traditional techniques for the placement of iliac screws often involve either substantial iliac muscle dissection for visualization of screw trajectory based on bony landmarks, or alternatively the use of intra-operative imaging to visualize these landmarks a...
متن کاملPercutaneous arthrodesis of sacro-iliac joint: a pilot study.
AIM Between 15-30% of patients presenting with low back pain have some SI joint involvement. The diagnosis of SI joint involvement in low back pain is quite difficult and depends on a detailed combination of clinical manoeuvres and injection tests. In 5% of patients with SI joint pain, the joint is physically unstable (termed disruption) resulting in ineffective medical and conservative therape...
متن کاملBiomechanical stability of bioabsorbable screws for fixation of acetabular osteotomies.
The purpose of this study was to compare the biomechanical stability of triple innominate osteotomies fixed with either bioabsorbable or stainless steel screws. Triple innominate osteotomies were performed on composite hemipelves and fixed with either three 4.5-mm bioabsorbable screws or three stainless steel 4.5-mm screws. Two screws were placed from the iliac wing into the acetabular fragment...
متن کاملPercutaneous Iliac Screws for Minimally Invasive Spinal Deformity Surgery
Introduction. Adult spinal deformity (ASD) surgeries carry significant morbidity, and this has led many surgeons to apply minimally invasive surgery (MIS) techniques to reduce the blood loss, infections, and other peri-operative complications. A spectrum of techniques for MIS correction of ASD has thus evolved, most recently the application of percutaneous iliac screws. Methods. Over an 18 mont...
متن کاملThe Strain at Bone-Implant Interface Determines the Effect of Spinopelvic Reconstruction following Total Sacrectomy: A Strain Gauge Analysis in Various Spinopelvic Constructs
PURPOSE There is still some controversy regarding the optimal biomechanical concept for spinopelvic stabilization following total sacrectomy for malignancy. Strains at specific anatomical sites at pelvis/sacrum and implants interfaces have been poorly investigated. Herein, we compared and analyzed the strains applied at key points at the bone-implant interface in four different spinopelvic cons...
