1. Abstract 1.1. Background Context Extreme lateral interbody fusion (XLIF) is a relatively recent minimally invasive fusion technique of the lumbar spine. A point of criticism is the risk of postoperative weakness of the psoas ascribed to neural injury. We postulate that the resulting hip flexion weakness is merely a temporary phenomenon due to po...

Background The anterior deltopectoral approach is the standard approach for performing the open Latarjet procedure. Through the use of a more medial and vertical skin incision, the scar can be cosmetically covered by the bra strap in women. We call this incision the bra strap incision. The intention of this study was (1) to elaborate if the bra str...
Article
Background and study aims: Perioperative use of anticoagulant and platelet-inhibiting agents by patients undergoing spine surgery poses the dilemma of increased risk of hemorrhage. We examined the standards of use for these medications and expert opinions through a nationwide survey. Materials and methods: An online-based survey was conducted by...
Article
Achieving sufficient mechanical purchase of pedicle screws in osteoporotic or previously instrumented bone is technically and biologically challenging. Techniques using different kinds of pedicle screws or methods of cement augmentation have been used to address this challenge, but are associated with difficult revisions and complications. The purp...
Article
Background: The Lenke classification is well established in differentiation of curve types in adolescent idiopathic scoliosis (AIS) and guides selection of fusion levels. However, to date, it has neglected the spinopelvic parameters that have been associated with compensatory mechanisms in balancing the human erect posture and adjacent segment pro...

Introduction: With increasing age, ubiquitous degeneration processes lead to a narrowing of the spinal canal. Degenerative lumbar spinal stenosis (DLSS) causes functional disability and is associated with back and lower extremity pain in older individuals. The goal of this study was to determine if decompression surgery can be performed safely and...

Background The Cobb angle measurement is well established for the measurement of coronal deformity aspect of scoliotic curves. The effect of positional differences in relation to the apex side of the scoliosis is not yet fully quantified. While theoretically plausible that positioning error with rotation toward the apex of the scoliosis would decre...

The patient-physician relation begins when the physician introduces himself with name and function. Most institutions request a nametag with name and function to be worn. Although nametags are consequently worn, the optimal position for the nametag is unknown. It was the purpose of this study to identify whether positioning the nametag on the right...

Background: While convergent placement of pedicle screws in the axial plane is known to be more advantageous biomechanically, surgeons intuitively aim toward a parallel placement of screws in the sagittal plane. It is however not clear whether parallel placement of screws in the sagittal plane is biomechanically superior to a non-parallel construc...

Aims: With increasing age, ubiquitous degeneration processes lead to a narrowing of the spinal canal. Degenerative lumbar spinal stenosis (DLSS) causes functional disability and is associated with back and lower extremity pain in older individuals. The goal of this study was to determine if outcome and quality of life might improve after decompress...
Article
Recurrence of anterior shoulder instability after operative repair is an uncommon but disabling condition for which treatment options have been insufficiently studied. Coracoid transfer as described by Latarjet is a highly successful primary operation for recurrent anterior shoulder instability. The purpose of this study was to verify the hypothesi...
