Prosthetic joint infection following hip fracture and degenerative hip disorder: a cohort study of three thousand, eight hundred and seven consecutive hip arthroplasties with a minimum follow-up of five years.

Purpose: Prosthetic joint infections (PJIs) occur on a regular basis and with an increasing incidence. Under reporting of complications to national registries and unreliable ICD-10 coding increases the risk of under estimating the true rate of PJIs after hip arthroplasty. Also, the microbiology and final outcome is less well described, especially for hip-fracture patients operated upon with primary and secondary fracture prostheses.

Low bone mineral density and fat-free mass in younger patients with a femoral neck fracture.

Background: Reduced bone mineral density (BMD) together with muscle wasting and dysfunction, that is sarcopenia, emerges as a risk factor for hip fracture. The aim of this study was to examine body composition and BMD and their relationship with trauma mechanisms in young and middle-aged patients with femoral neck fracture.

Materials And Methods: Altogether, 185 patients with femoral neck fracture aged 20-69 were included.

Unipolar hemiarthroplasty versus bipolar hemiarthroplasty in patients with displaced femoral neck fractures: a four-year follow-up of a randomised controlled trial.

Purpose: The treatment of choice for a displaced femoral neck fracture in the most elderly patients is a cemented hemiarthroplasty (HA). The optimal design, unipolar or bipolar head, remains unclear. The possible advantages of a bipolar HA are a better range of motion and less acetabular wear.

Acetabular fractures in the elderly treated with a primary Burch-Schneider reinforcement ring, autologous bone graft, and a total hip arthroplasty: a prospective study with a 4-year follow-up.

Objectives: To investigate the clinical and radiologic outcomes in elderly patients suffering from an acetabular fracture operated with an acute primary acetabular reinforcement ring, autologous bone graft, and a total hip arthroplasty (THA).

Design: Prospective cohort study.

Setting: Tertiary care university hospital.

Internal fixation versus cemented hemiarthroplasty for displaced femoral neck fractures in patients with severe cognitive dysfunction: a randomized controlled trial.

Objectives: To compare the outcome of internal fixation (IF) versus a cemented hemiarthroplasty (HA) in patients with a displaced femoral neck fracture and a severe cognitive dysfunction.

Design: A prospective randomized controlled trial.

Setting: A tertiary care university hospital.

Tourniquet cuff pressure and nerve injury in knee arthroplasty in a bloodless field: a neurophysiological study.

Background And Purpose: Tourniquet-related nerve injuries remain a concern in orthopedic surgery. The cuff pressures used today are generally lower, and therefore a decreasing incidence of peripheral nerve injuries might also be expected. However, there have been few neurophysiological studies describing the outcome after bloodless field surgery.

Tourniquet time affects postoperative complications after knee arthroplasty.

Purpose: Pneumatic tourniquets are frequently used in knee arthroplasty surgery. However, there is a lack of evidence to define safe tourniquet time in lower limb surgery. The primary aim of this study was to investigate whether tourniquet time influences the risk of postoperative complications after primary and secondary knee arthroplasty.

Risk factors for osteoporosis are common in young and middle-aged patients with femoral neck fractures regardless of trauma mechanism.

Background And Purpose: There have been few prospective studies examining young and middle-aged patients with hip fracture. We therefore investigated background data, risk factors, and the trauma mechanism in young and middle-aged patients with femoral neck fracture.

Patients And Methods: 185 patients, 27 young (20-49 years old) and 158 middle-aged (50-69 years old) were prospectively included in a multicenter study lasting 3 years.

Lower tourniquet cuff pressure reduces postoperative wound complications after total knee arthroplasty: a randomized controlled study of 164 patients.

Background: Measurement of limb occlusion pressure before surgery might lead to the use of a lower tourniquet cuff pressure during surgery and thereby reduce the risk of postoperative pain and complications. The primary aim of this study was to investigate whether the limb-occlusion-pressure method reduces the tourniquet cuff pressure used during total knee arthroplasty and if this leads to less postoperative pain compared with that experienced by patients on whom this method is not used. The secondary aim was to investigate whether there were any differences regarding the quality of the bloodless field, range of motion, and postoperative wound complications.

Comparison of bipolar hemiarthroplasty with total hip arthroplasty for displaced femoral neck fractures: a concise four-year follow-up of a randomized trial.

We performed a four-year follow-up of a randomized controlled trial involving 120 elderly patients with an acute displaced femoral neck fracture who were randomized to treatment with either a bipolar hemiarthroplasty or a total hip arthroplasty. The difference in hip function (as indicated by the Harris hip score) in favor of the total hip arthroplasty group that was previously reported at one year persisted and seemed to increase with time (mean score, 87 compared with 78 at twenty-four months [p < 0.001] and 89 compared with 75 at forty-eight months [p < 0.

Unipolar hemiarthroplasty versus bipolar hemiarthroplasty in the most elderly patients with displaced femoral neck fractures: a randomised, controlled trial.

Purpose: Hemiarthroplasty (HA) is generally considered to be the treatment of choice in the most elderly patients with a displaced fracture of the femoral neck. However, there is inadequate evidence to support the choice between unipolar HA or bipolar HA. The primary aim of this study was to analyse the outcome regarding hip function and health-related quality of life (HRQoL) in patients randomised to either a unipolar or bipolar HA.

Responsiveness of the Short Musculoskeletal Function Assessment (SMFA) in patients with femoral neck fractures.

Purpose: The aim of this study was to evaluate the internal and external responsiveness of the Short Musculoskeletal Function Assessment (SMFA), i.e. the instrument's ability to capture clinically important changes, in patients with hip fractures within the context of a randomized controlled trial.

Displaced femoral neck fracture: comparison of primary total hip replacement with secondary replacement after failed internal fixation: a 2-year follow-up of 84 patients.

Introduction: Recent randomized controlled trials have shown that for the active and lucid elderly patient with a displaced femoral neck fracture, a primary total hip replacement (THR) is superior to internal fixation (IF) regarding the need for secondary surgery, hip function and health-related quality of life (HRQoL). Despite the high failure rate for IF, the method is still recommended for this patient cohort by some authors. One argument is that if IF fails, there is always the possibility of performing a secondary salvage THR.

Comparison of internal fixation with total hip replacement for displaced femoral neck fractures. Randomized, controlled trial performed at four years.

Background: Recent randomized, controlled trials performed at two years postoperatively have shown that a primary total hip replacement is superior to internal fixation for the treatment of a displaced femoral neck fracture in a relatively healthy, mentally competent, elderly patient. The primary aim of the present study was to evaluate the outcomes at four years.

Methods: One hundred and two patients (mean age, eighty years) who had an acute displaced femoral neck fracture were randomly allocated to be treated with total hip replacement or internal fixation.

Primary total hip arthroplasty with a Burch-Schneider antiprotrusion cage and autologous bone grafting for acetabular fractures in elderly patients.

Objectives: To investigate the clinical and functional outcome in an elderly population with acetabular fractures after low-energy trauma treated acutely with a total hip arthroplasty supported by a reinforcement ring (Burch-Schneider antiprotrusion cage) and autologous bone grafting of the acetabulum.

Setting: University hospital.

Design: Retrospective clinical study.
