The Effect of Nutritional Status in the Treatment of Periprosthetic Joint Infections in Total Hip Arthroplasty.

Background: Periprosthetic joint infections (PJIs) continue to be a complication that plagues arthroplasty. Albumin is a surrogate marker for nutrition as well as chronic inflammation, and hypoalbuminemia increases the risk of complications in arthroplasty. Patients with PJI are at increased risk for malnutrition and complications.

Treating Sleep Disorders After Total Hip and Total Knee Arthroplasty.

Disorders of sleep are common after total hip and knee arthroplasty and may contribute to patient dissatisfaction and poorer outcomes in the early postoperative period. Multiple factors contribute to sleep disorders, including poorly controlled pain, opioid medication, perioperative stress, and anxiety. Both pharmacologic and nonpharmacologic methods have been used for perioperative sleep disorders, but there is no consensus on the optimal treatment.

Surgical Versus Nonsurgical Management of Acetabular Fractures With Associated Patterns in Elderly Patients: Factors Affecting Outcomes.

Introduction: Among elderly patients, anterior column posterior hemitransverse (ACPHT) and associated both column (ABC) are common acetabular fracture patterns after low-energy mechanisms. Given the paucity of outcomes data in this cohort, the goal of this study was to determine the favorability of results with surgical versus nonsurgical management. Secondarily, factors linked with poor functional outcomes were assessed.

Outcomes of Pediatric Posterior Cruciate Ligament Reconstruction: A Systematic Review.

Background: Little has been reported in the literature regarding surgical treatment of posterior cruciate ligament (PCL) injuries in pediatric patients.

Purpose/hypothesis: The purpose was to evaluate presentation, injury pattern, outcomes, and complications of surgically managed PCL injuries in pediatric patients. It was hypothesized that pediatric patients would have good patient-reported outcomes and no significant radiographic changes or complications.

Survivorship of the Hip Joint After Acetabulum Fracture.

Purpose: The purposes of this study were to determine the rate of failure of the hip joint after acetabulum fracture and to identify risk factors.

Methods: Acetabulum fractures treated over 17 years at a level-1 trauma center were reviewed. Patient, injury, and treatment factors were assessed regarding possible association with failure of the hip joint: end-stage arthrosis and/or total hip arthroplasty (THA).

Factors influencing functional outcomes following open reduction internal fixation of acetabular fractures.

Introduction: Recent large series of patient-reported outcomes after acetabulum fracture are limited, and potentially modifiable risk factors may be unidentified. The goal of this study was to describe patient and injury factors which negatively influence functional outcomes following operative management of acetabular fractures.

Methods: 699 patients with acetabular fractures were treated with open reduction and internal fixation (ORIF).

Nerve Injury With Acetabulum Fractures: Incidence and Factors Affecting Recovery.

Objectives: To determine factors associated with nerve injury after acetabulum fracture and to evaluate recovery and outcomes.

Design: Retrospective cohort study.

Setting: Level 1 trauma center.

Clinical and Functional Results of 119 Patients With Knee Dislocations.

Objectives: To describe clinical results and functional outcomes of knee dislocations treated with a consistent strategy within our institution.

Design: Retrospective case series.

Setting: Level 1 trauma center.

Can Vascular Injury be Appropriately Assessed With Physical Examination After Knee Dislocation?

Background: Knee dislocations are rare injuries with potentially devastating vascular complications. An expeditious and accurate diagnosis is necessary, as failing to diagnose vascular injury can result in amputation; however, the best diagnostic approach remains controversial.

Questions/purposes: We asked: (1) What patient factors are predictors of vascular injury after knee dislocation? (2) What are the diagnostic utilities of palpable dorsalis pedis or posterior tibial pulses, and the presence of an ankle-brachial index (ABI) of 0.

Acetabular fractures converted to total hip arthroplasties in the elderly: how does function compare to primary total hip arthroplasty?

Objectives: Little data exist regarding the outcomes of total hip arthroplasty (THA) after acetabular fracture treatment failure. We hypothesize that these patients achieve a lower level of function than those who undergo primary THA for osteoarthritis (atraumatic).

Design: Retrospective review.

Do flexion extension plain films facilitate treatment after trauma?

We hypothesized that flexion extension (FE) films do not facilitate the diagnosis or treatment of ligamentous injury of the cervical spine after blunt trauma. From January 2000 to December 2008 we reviewed all patients who underwent FE films and compared five-view plain films (5 view) and cervical spine CTC with FE in the diagnosis of ligamentous injury. There were 22,929 patients with blunt trauma and of these, 271 patients underwent 303 FE films.

Flexion-extension cervical spine plain films compared with MRI in the diagnosis of ligamentous injury.

The purpose of this study was to compare flexion-extension (FE) plain films with MRI as the gold standard in the diagnosis of ligamentous injury (LI) of the cervical spine after trauma. A retrospective review of patients sustaining blunt trauma from January 2000 to December 2008 (n = 22929) who had both FE and MRI of the cervical spine was performed. Two hundred seventy-one patients had 303 FE films.
