OBJECTIVE: To explore whether the iliac wing influenced L5 PS fixation and to propose methods to reduce such influence. METHODS: A total of 100 computed tomography scans (from 50 males and 50 females) of the lower lumbar region and pelvis were obtained and three-dimensionally reconstructed. Cylinders with 6.5-mm diameters were drawn to simulate the different trajectories of L5 PSs. The maximum lengths and lateral angles of trajectories, and the vertical distances from the inner edge of the iliac wing to these trajectories, were measured...

OBJECTIVE S-2 alar iliac (S2AI) screws are commonly used as anchors for lumbosacral fixation. A serious potential complication of screw insertion is major vascular injury due to anterior or caudal screw deviation. To avoid screw deviation, the pelvic inlet view on intraoperative fluoroscopy images is recommended. However, there has been no detailed investigation of optimal fluoroscopic incline with the pelvic inlet view. The purpose of this study was to investigate the safety margins and to optimize fluoroscopic settings to avoid screw deviation with 2 reported insertion techniques using 3D analysis software and CT...

Matthew T Provencher
Arthroscopic techniques are an emerging technology to deal with glenoid bone defects in patients with anterior shoulder instability, and improvements are being made to safely minimize the risk of injury to the anterior neurovascular structures including the axillary nerve. Arthroscopic glenoid reconstruction is a technically demanding procedure, but it does have promising short-term outcomes. I truly like the concept of anterior (and also posterior) bone grafting for defects of the glenoid, including the arthroscopic Latarjet...

Spinopelvic fixation provides an important anchor for long fusions in spinal deformity surgery, and it is also used in the treatment of other spine pathologies. Iliac screws are known to sometimes require reoperation due to pain resulting from hardware prominence and skin injury. S-2 alar/iliac (S2AI) screws do not often require removal, but they may provide inadequate fixation in select cases. In this paper the authors describe a technique for S-1 alar/iliac screws that may be used independently or as a supplement to S2AI screws...

Recently, the one-stage posterior approach for treating spinal tuberculosis (TB) has gained popularity. However, large bony defects after debridement remain a major challenge in posterior surgery. The present retrospective study aims to compare the clinical outcomes of posterior-only surgical management by titanium mesh versus iliac bone grafts for treating lumbosacral TB. This was a retrospective cohort study. From January 2006 to April 2012, 36 patients with lumbosacral TB were treated at our department. The 36 cases were divided into 2 groups: 17 patients in Group A (titanium mesh) underwent one-stage posterior internal fixation, debridement, and titanium mesh bone fusion...

We have devised a medial peri-articular osteotomy, the distal tibial oblique osteotomy (DTOO), and have used this technique since 1994 for ankle osteoarthritis of advanced and late stages associated with varus inclination. This report describes the surgical technique and its applicability. DTOO can be used for cases of varus ankle osteoarthritis with a range of the ankle joint movement of at least 10° or more. The osteotomy is obliquely directed cut across the distal tibia from proximal-medial to distal lateral and is of an opening-wedge type with the centre of rotation coincident with the centre of the tibiofibular joint...

Achieving lumbosacral fusion through spinopelvic fixation is an important and challenging aspect of spinal deformity surgery. Numerous instrumentation techniques are available, with iliac screws and S2-alar-iliac (SRAI) screws being most commonly used today. However, the increasing popularity of minimally invasive sacroiliac (SI) fusion as a common procedure performed for SI joint pain presents a distinct challenge in complex adult deformity cases requiring iliac screw fixation. We report a case of a 71-year-old female with a longstanding history of spinal deformity status-post T11-L5 fusion and a subsequent right-sided SI joint fusion who presented with sagittal imbalance...
