5-year migration and inducible displacement of the uncemented LCS and ATTUNE rotating platform knee systems: a secondary report of a randomized controlled RSA trial.
Acta Orthop

Department of Orthopaedics, Spaarne Gasthuis, Hoofddorp; Department of Oral Cell Biology, Academic Centre for Dentistry (ACTA), University of Amsterdam and Vrije Universiteit Amsterdam, Amsterdam, the Netherlands.
Background And Purpose: Early migration of the uncemented cruciate-sacrificing rotating platform ATTUNE and Low Contact Stress (LCS) tibial components was classified as at-risk for aseptic loosening rates exceeding 6.5% at 15 years based on recent fixation-specific migration thresholds. In this secondary report of a randomized controlled trial (RCT) we aimed to evaluate whether the 5-year migration, inducible displacement, and the clinical outcome of the ATTUNE components were comparable to those of the LCS.

Investigation Performed at the University of Washington, Department of Orthopaedic Surgery and Sports Medicine, Seattle, WA, USA. Electronic address:
Background: While stress shielding and adaptive bone changes around the humeral component are often observed after shoulder arthroplasty, the potential causative factors and clinical significance of these findings at mid-term follow-up have not been well elucidated. The purpose of this study was to investigate the frequency, patterns and clinical significance of radiographic findings around the humeral component of total shoulder arthroplasty (TSA) and hemiarthroplasty (HA) at minimum 4-year follow-up.
Methods: The 6-week and minimum 4-year radiographs of patients who underwent HA and TSA were evaluated for filling ratios, changes in the humeral bone surrounding the component, and component shift or subsidence.
Kyphectomy followed by self-sliding pedicle screw and translumbosacral rod impaction and fixation: a novel growth-friendly technique in myelomeningocele patients.
Spine Deform

Pediatrics and Neurosurgery, Cedars Sinai Medical Center, Los Angeles, CA, USA.
Introduction: Congenital lumbar kyphosis is present in about 15% of patients with myelomeningocele. Worsening of deformity with complications such as chronic skin ulcers and bone exposure is common. In patients under 8 years of age, treatment becomes even more challenging: in addition to resecting the apex of the kyphotic deformity, we should ideally stabilize the spine with fixation methods that do not interrupt the growth of the rib cage, associated with the challenging pelvic fixation in this population.

POEMS syndrome is a multisystemic disease associated with monoclonal plasma cell disorders. Although the presence of bone lesions is included in the diagnostic criteria, their precise manifestations remain unknown. Here, we retrospectively analyzed the bone lesions in patients with POEMS syndrome and evaluated their clinical features.
