Saverio Affatato, Dalila Caputo, Barbara Bordini
PURPOSE: The effect of being obese on the long-term survival of total joint arthroplasty is persistently discussed. Considering only studies with large cohort of patients and meta-analysis, a high body mass index has been correlated with a higher incidence of complication but not univocally with a lower survival rate. In this study, we analyzed, retrospectively, the data of patients that received unicompartmental knee prostheses in order to examine if obesity has an effect on clinical outcomes...

Chi Xu, Heng Guo, Ji-Ying Chen
BACKGROUND: The purpose of this study was to determine whether frozen sections can increase diagnostic values of serological tests for the assessment of periprosthetic joint infection (PJI) in patients without synovial fluid analyses. METHODS: A retrospective review of 128 revision arthroplasties (79 hips and 49 knees) from January 2016 to December 2017 was performed. Diagnosis of PJI was based on the Musculoskeletal Infection Society criteria for infection. Three diagnostic models for PJI, with model 1 including erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP), model 2 including model 1 plus frozen sections > 5 polymorphonuclear neutrophil (PMN)s per high-power field (HPF), and model 3 including model 1 plus frozen sections > 10 PMNs per HPF, were developed...

PURPOSE: The distal femoral varization osteotomy (DFVO) by a lateral opening wedge osteotomy is an established intervention for patients suffering from lateral femoro-tibial osteoarthritis on a genu valgum deformity. In order to improve the accuracy of this correction, the use of a customized cutting guide (PSI) has been proposed as an alternative to conventional technique. The objective of our study was to compare the accuracy of post-operative alignment following DFVO in the coronal and sagittal plane using either a conventional abacus technique or PSI guide...

PURPOSE: Cervical disc herniation is a common pathology. It can be treated by different surgical procedures. We aimed to list and analyzed every available surgical option. We focused on the comparison between anterior cervical decompression and fusion and cervical disc arthroplasty. RESULTS: The anterior approach is the most commonly used to achieve decompression and fusion by the mean of autograft or cage that could also be combined with anterior plating. Anterior procedures without fusion have shown good outcomes but are limited by post-operative cervicalgia and kyphotic events...

REVIEW
Charlie Bouthors, Ahmed Benzakour, Charles Court
BACKGROUND: Surgical treatment of thoracic disc herniation (TDH) is technically demanding due to its proximity to the spinal cord. METHODS: Literature review. RESULTS: Symptomatic TDH is a rare condition predominantly localized between T8 and L1. Surgical indications include intractable back or radicular pain, neurological deficits, and myelopathy signs. Giant calcified TDH (> 40% spinal canal occupation) are frequently associated with myelopathy, intradural extension, and post-operative complications...

REVIEW
Andrew Quaile
Cauda equina syndrome is a devastating condition often following an innocent pathology in the form of a disc prolapse. The effect on sufferers, however, can be lifelong. It is necessary to make a diagnosis as expeditiously as possible via adequate history, clinical examination and appropriate imaging to offer treatment, in the form of decompressive surgery within 48 hours. It is extremely important to communicate adequately with the patient and their family recording all the relevant details including those of expected outcome...

INTRODUCTION: Instability is a major complication in revision total hip arthroplasty (THA). Dual mobility (DM) cups were shown to reduce the risk of post-operative implant dislocation. Few case-series studies assessed the outcomes of cemented DM cups when associated to acetabular reconstruction antiprotrusio cages. No published comparative studies were found to look for outcome differences between standard cups (SC) and DM cups in first revision THA associated with a Kerboull plate (KP) and acetabular bone grafting...
