INTRODUCTION: A typical feature of inferior glenoid fractures is a distal fragment separated from the glenoid fossa. In most cases, the inferior glenoid fractures are associated with a fracture of the scapular body. However, there are no detailed studies of inferior glenoid fractures, and only brief mentions can be found in the literature in this respect. MATERIAL AND METHODS: The basic group comprised 42 patients, with the mean age of 48 years, who sustained 42 fractures of the inferior glenoid...

PURPOSE: Little data is available on the number of osteosynthesis of limbs in a country. Incidence of osteosynthesis is an essential element for the formation and organization of care. Based on the data from the work of the Hospital Information Technology Agency ( http://www.atih.sante.fr/ ) and available in open access, we wanted to know the incidence of the number of osteosynthesis performed in France and their evolution over ten years between 2006 and 2015. METHODS: The data analyzed are derived from the website of the technical agency of information on the hospitalization (ATIH)...

INTRODUCTION: In order to avoid pseudarthrosis in adolescent idiopathic (AIS) patients, it is recommended to bring additional bone graft or substitute. Modern rigid instrumentations have been shown to provide less pseudarthroses even without bone substitutes. The aim of our study was to determine the impact of using bones substitutes on fusion rates in adolescent idiopathic scoliosis patients undergoing PSF with sublaminar bands. METHOD: AIS patients scheduled to undergo PSF with sublaminar bands were prospectively enrolled into this study and not given any bone substitutes (no-substitute group)...

STUDY DESIGN: This was a retrospective study to evaluate clinical characteristics of patients who developed symptomatic spinal epidural haematoma (SSEH) after spinal surgery. OBJECTIVE: The objective was to determine clinical parameters associated with the development of SSEH after spinal surgery, and to discuss clinical management and possible preventive measures. Although the incidence rate of SSEH is low, the neurological sequelae are devastating. There are limited reports which identify risk factors for SSEH because of the rarity of the condition...

INTRODUCTION: Due to a supposed high rate of nonunions in lateral open wedge distal femur osteotomy (LOWDFO), the medial closing wedge technique has been favoured for a long time. The aim of this study was to report the occurrence of delayed- and nonunions following LOWDFO. We hypothesized that the occurrence of nonunions needing revision surgery is comparable to medial closing osteotomies. METHODS: Forty-one patients were treated with LOWDFO with a minimum follow-up of 12 months...

PURPOSE: The aim of this study was to compare two methods of two-stage surgery for PJI (periprosthetic joint infection) after THA (total hip arthroplasty): one with and one without the use of an antibiotic-loaded cement spacer. METHODS: This retrospective study was performed on 99 consecutive patients (99 hips) with a minimum follow-up of 24 months. Patients were divided into two groups: (1) in whom the operation was performed using a spacer, and (2) for whom a spacer was not used...

PURPOSE: Patient-specific instrumentation (PSI) has the potential to offer numerous benefits-not least of all, improved resection accuracy; but its potential has not been realised in clinical studies. An explanation may be the focus of such studies on the total knee replacement (TKR-a common procedure, with which surgeons are generally very familiar. Consequently, we sought to investigate the potential role of PSI in guiding novice surgeons to perform the more technically demanding and less familiar lateral unicondylar knee replacement (LUKR)...

PURPOSE: The primary objective was to describe the reasons for surgical re-intervention after radial head arthroplasty. The secondary objective was to analyze the radiographic and clinical outcomes after surgical re-intervention at the elbow with implant conservation. METHODS: Among the 70 radial head arthroplasties with bipolar radial head implant performed between 2002 and 2014, 29 required surgical re-interventions. Reasons for surgical re-intervention were gathered from operative notes and follow-up documentation...

PURPOSE: The aim of this study was to evaluate mid-term outcomes of Bankart repair with Hill-Sachs remplissage (BHSR) and to highlight prognostic factors of failure. METHODS: Thirty-four patients operated on for anterior shoulder instability with BHSR were enrolled in a prospective non-randomised study. Clinical and radiographic evaluation was performed at 1.5, three, six months and yearly thereafter. Outcome measures included Rowe and Walch-Duplay score. RESULTS: At mean follow-up of 35 months (24-63), the Rowe and Walch-Duplay scores reached respectively 92...

PURPOSE: Varus failure is one of the most common failure modes following surgical treatment of proximal humeral fractures. Straight antegrade nails (SAN) theoretically provide increased stability by anchoring to the densest zone of the proximal humerus (subchondral zone) with the end of the nail. The aim of this study was to biomechanically investigate the characteristics of this "proximal anchoring point" (PAP). We hypothesized that the PAP would improve stability compared to the same construct without the PAP...

INTRODUCTION: Morphological studies of the humerus have shown that the position of the bicipital groove varies with the individual and the retroversion of the humeral head. Depending on the authors, these two parameters are independent or associated. This study evaluated the relationship between the humeral head axis and its retroversion and the bicipital groove relative to the humeral biepicondylar line. MATERIALS AND METHODS: Seventy cadaveric humeri were scanned to obtain 3D reconstructions...

PURPOSE: Eight patients treated with kinematically-aligned (KA) total knee arthroplasty (TKA) presented with tibial component failure. We determined whether radiographic measurements and clinical characteristics are different between patients with and without tibial component failure to identify mechanisms of failure and strategies to reduce the risk. METHODS: Out of 3,212 primary TKAs (2,725 TKAs with a two-year minimum follow up), of which all were performed with KA, eight patients presented with tibial component failure...

BACKGROUND: Various types of dressing materials are available for wound care following hip and knee arthroplasty. However, it is unclear if one material is more beneficial than the others in terms of wound complications and fluid handling capacity. RESEARCH QUESTIONS: We performed a meta-analysis of randomized controlled trials comparing alternative wound dressing materials for the post-operative management of wounds following THA and TKA with respect to (1) incidence of wound complications including infection and (2) fluid handling capacity...

PURPOSE: There have been few large sample studies reporting the midterm outcome of Oxford phase 3 unicompartmental knee arthroplasty (UKA) in Asian patients. METHODS: The study included 708 consecutive medial Oxford UKAs between February 2005 and May 2014 in Chinese patients. All cases were performed for the recommended indications with a minimally-invasive surgical technique. The functional and radiological outcomes were subsequently examined. In particular, we divided patients into the spontaneous osteonecrosis of the knee (SONK) group and the osteoarthritis (OA) group...

BACKGROUND & PURPOSE: Increasing our appreciation of the historical foundations of hip arthroscopy offers greater insight and understanding of the field's current and future applications. This article offers a broad history of the progress of hip arthroscopy. METHODS: Hip arthroscopy's development from the early technologies of endoscopy to the present day is described through a review of the available literature. RESULTS: Endoscopic science begins with the Lichtleiter, developed by Phillip Bozzini (1779-1809) in 1806, but endoscopes were not applied to joints until 1912, as presented by Severin Nordentoft (1866-1922)...

PURPOSE: Short stem total hip arthroplasty (SHA) has gained increasing popularity as it conserves bone stock and is supposed to allow revision with a conventional stem. However, no study has evaluated whether the revision of a SHA with a standard total hip arthroplasty (THA) stem provides sufficient primary stability to allow osseous integration. METHODS: A neck preserving SHA (Metha) and a standard THA (CLS) stem were implanted into six composite femurs respectively and dynamically loaded (300-1700 N, 1 Hz)...
