Although the clinical consequences of femoroacetabular impingement have been well described, little is known about prevalence anatomical malformations associated with this condition in general population, natural history condition, and risk estimates for development osteoarthritis.The study material was derived from a cross-sectional population-based radiographic questionnaire database 4151 individuals Copenhagen Osteoarthritis Substudy cohort between 1991 1994. The subjects were primarily...

Background: We hypothesized that undergoing surgery as soon possible reduces early mortality in patients with a proximal femoral fracture. Our aim was to evaluate the association between surgical delay and these patients. Methods: performed retrospective analysis of prospectively collected data from Danish Fracture Database Civil Registration System on who were fifty years age or older had undergone for Femoral head fracture (classified OTA/AO 31C per classification system), high-energy...

Background: Reoperations after intertrochanteric fractures are often necessitated by fracture displacement following mobilization of the patient. The biomechanical complexity fracture, position implant, and patient's characteristics known to influence postoperative outcome. We investigated importance an intact lateral femoral wall as a factor in fixation with sliding compression hip screw. Methods: Two hundred fourteen consecutive patients were treated 135° screw four-hole side-plate between...

Femoroacetabular cam impingement is thought to be a cause of premature osteoarthritis the hip. The presence malformation was determined in 2803 standardised anteroposterior (AP) pelvic radiographs from Copenhagen Osteoarthritis Study by measuring alpha (α) angle and triangular index, new measure asphericity femoral head. In addition, α-angle index were assessed on AP lateral hip 82 men women randomly selected patients scheduled for total replacement (THR). influence varying rotation α also...

Perioperative anemia leads to increased morbidity and mortality potentially inhibits rehabilitation after hip fracture surgery. As such, the optimum transfusion threshold surgery is unknown.A total of 120 elderly, cognitively intact patients admitted from their own home were randomly assigned receive at a hemoglobin 10.0 g per dL (liberal) versus 8.0 (restrictive) in entire perioperative period. Patients treated according well-defined multimodal program. Primary outcome was postoperative...

Highly crosslinked polyethylene (HXLPE) in THA was developed to reduce particle-induced periprosthetic osteolysis. A series of clinical studies were initiated determine the efficacy as judged by patient-reported scores, radiographic osteolysis, and wear analysis one form HXLPE.The purposes this (1) rates HXLPE; (2) report long-term (7-10 years) outcome measures; (3) assess effect femoral head size on wear; (4) incidence osteolysis.A single-center two multicenter conducted 768 primary...

Background and purpose Preoperative posterior tilt in undisplaced (Garden I–II) femoral neck fractures is thought to influence rates of reoperation. However, an exact method for its measurement has not yet been presented. We designed a new on preoperative lateral radiographs investigated association with later reoperation.Patients methods A consecutive series 113 patients, ≥ 60 years age treated two parallel implants, was assessed regarding patient characteristics, radiographs, rate...

Aims We chose unstable extra-capsular hip fractures as our study group because these types of suffer the largest blood loss. hypothesised that tranexamic acid (TXA) would reduce total loss (TBL) in hip. Patients and Methods A single-centre placebo-controlled double-blinded randomised clinical trial was performed to test hypothesis on patients undergoing surgery for fractures. For reasons outside control investigators, stopped before reaching 120 included planned protocol. Results In all 72...

Purpose: The patient's ability to complete their planned physiotherapy session after hip fracture surgery has been proposed as an independent predictor for achieving basic mobility independency upon hospital discharge. However, knowledge of factors limiting is sparse. We therefore examined patient reported sessions well limitations not in early surgery.Methods: A total 204 consecutive patients with a (mean (SD) age 80 (9.9) years, 47 were admitted from nursing home) treated accordance...

Treatment of hip fracture patients is controversial. We implemented a new operative and supervision algorithm (the Hvidovre algorithm) for surgical treatment all fractures, primarily based on own previously published results.2,000 consecutive over 50 years age who were admitted operated because prospectively included. 1,000 these included after implementation the algorithm. Demographic parameters, hospital treatment, reoperations within first postoperative year assessed from patient...

Postoperative delirium is common after hip fracture surgery, and may have a neuro-inflammatory cause. We conducted single-centre, randomised, double-blind, placebo-controlled trial of 117 older patients to see if single, pre-operative intravenous dose 125 mg methylprednisolone could reduce the severity and/or incidence postoperative delirium, assessed using Confusion Assessment Method score. Modified intention-to-treat analysis found no significant difference in our primary outcome, median...

Prior studies have shown that patients with dementia are at risk of receiving insufficient treatment for pain after a hip fracture. We therefore hypothesized elderly fracture received less postoperative than those without dementia. All (age ≥65 years) who had been operated on in the Copenhagen University Hospital region 2009 were included. Data about analgesic use first 72 h surgery acquired from hospitals' electronic medication system and linked information dementia, comorbidity, prior drug...

Background and purpose In recent years, intramedullary nails (INs) for the treatment of pertrochanteric hip fractures have gained prominence relative to conventional, sliding screws (SHSs). There is little empirical background this development, however. A previous series ours suggested that use SHS was not adequate in situations with fragile or fractured lateral femoral walls, where it often led lack healing a maximally telescoped position. We hypothesized INs would be superior implant these...

Internal fixation of hip fractures is a common and important procedure that orthopedic surgeons must master early in their career. Virtual-reality training could improve initial skills, simulation-based test would make it possible to ensure basic competency junior before they proceed supervised practice on patients. The aim this study was develop reliable valid with credible pass/fail standards.20 physicians (10 untrained novices 10 experienced surgeons) each performed 3 internal procedures...

early mobilization after hip fracture (HF) is an important predictor of outcome, but knowledge the consequences not achieving pre-fracture basic mobility status in acute hospital recovery sparse. we examined whether regain evaluated with cumulated ambulation score (CAS) at discharge was associated 30-day post-discharge mortality and readmission. this a population-based cohort study. using nationwide Danish Multidisciplinary HF Database from January 2015 through December 2015, 5,147 patients...

Importance Patients with a hip fracture lose more than 50% knee-extension strength in the fractured limb within one week of surgery. Hence, immediate progressive training following surgery may be rational, but feasibility unknown. Objective To examine in-hospital implemented acute ward surgery, based on pre-specified criteria for feasibility. Design, Setting and A prospective cohort study conducted an orthopedic unit at university hospital. consecutive sample 36 patients, 18 cervical...

Early mobilization following hip fracture surgery reduces medical complications and mortality, but may increase the risk of falling. The aim was to objectively measure physical activity (time spent upright) first week after relate it functional performance fear falling at discharge. 24-hr upright time measured for a median six days using thigh-worn accelerometer in 37 patients (mean 80 years ± 8.4) increased from 13 (IQR 6-31) min 46 (11-107) day 7. More discharge associated with less (r =...

Abstract Background Several factors might be associated with risk of dislocating following uncemented hemiarthroplasty (HA) due to femoral neck fracture (FNF). Current evidence is limited great variance in reported incidence dislocation (1–15%). Aim this study was identify the cumulative first-time HA and factors. Method We performed a retrospective cohort patients receiving an (BFX Biomet stem, posterior approach) at Copenhagen University Hospital, Bispebjerg, 2010–2016. Patients were...

Background and purpose Fixation of unstable trochanteric fractures is challenging. Application a circumferential wire may facilitate bone contact avoid postoperative fracture displacement. However, the use wires remains controversial due to possible disturbance blood supply underlying bone. We evaluated results applied wires, concentrating mainly on complications reoperations.Patients methods 60 patients with (1 or more) an intramedullary nail were included from 2 centers. retrospectively...

Question Is acute in-hospital physiotherapy with additional progressive knee-extension strength training (ST) of the fractured limb more effective in reducing deficit at follow-up compared to without patients a hip fracture? Design Assessor blinded, randomised controlled trial intention-to-treat analysis. Participants 90 fracture admitted an orthopaedic Hip Fracture Unit university hospital between October 2013 and May 2015. Intervention Daily or (10RM), 3 x 10 repetitions, using ankle...
