Immediate weightbearing is safe after revision total hip arthroplasty for Vancouver B2/B3 periprosthetic femur fractures.

Introduction: Modular fluted, tapered stems provide a reliable treatment for Vancouver B2/B3 fractures. Historically, these patients had weightbearing restrictions postoperatively. Although full immediate postoperative weightbearing may provide benefits in this patient population, stem subsidence is a concern.

Outcomes of Tibiotalocalcaneal Hindfoot Fusion Nails Used for Acute Lower Extremity Trauma in a High-Risk Patient Population.

Objective: To determine the outcomes of high-risk patients treated with tibiotalocalcaneal hindfoot fusion nails.

Design: Retrospective case series.

Setting: Level I trauma center.

The Role of Dual-Mobility Components in Total Hip Arthroplasty.

➤: Dual mobility (DM) refers to a now widely available option for total hip articulation. DM implants feature a small inner head, a hard bearing, that connects via a taper fit onto the femoral trunnion. This head freely rotates but is encased inside a larger, outer polyethylene head that articulates with a smooth acetabular component.

Proximal femoral replacement using the direct anterior approach to the hip.

Objective: Proximal femoral replacement (PFR) is a salvage procedure originally developed for reconstruction after resection of sarcomas and metastatic cancer. These techniques can also be adapted for the treatment of non-oncologic reconstruction for cases involving massive proximal bone loss. The direct anterior approach (DAA) is readily utilized for revision total hip arthroplasty (THA), but there have been few reports of its use for proximal femoral replacement.

Extensile Femoral Exposure for the Direct Anterior Approach to the Hip.

The direct anterior approach to the hip is immediately extensile to access the entire femur for a wide range of conversion hip replacement and revision hip replacement scenarios. Multiple types of trochanteric osteotomies and complex procedures including proximal femoral replacement can be accomplished through extension of the direct anterior approach distally.

Extensile Acetabular Exposure for the Direct Anterior Approach to the Hip.

The direct anterior approach to the hip is immediately extensile for complex acetabular reconstruction including placement of augments, cages, and bone graft both on the outer and inner table of the iliac wing. This approach is also useful for exposure and removal of intrapelvic implants.

Poor Agreement Between Next-Generation DNA Sequencing and Bacterial Cultures in Orthopaedic Trauma Procedures.

Background: Next-generation DNA sequencing (NGS) detects bacteria-specific DNA corresponding to the 16S ribosomal RNA gene and can identify bacterial presence with greater accuracy than traditional culture methods. The clinical relevance of these findings is unknown. The purpose of the present study was to compare the results from bacterial culture and NGS in order to characterize the potential use of NGS in orthopaedic trauma patients.

Inpatient compliance with venous thromboembolism prophylaxis after orthopaedic trauma: results from a randomized controlled trial of aspirin versus low molecular weight heparin.

Objectives: To compare inpatient compliance with venous thromboembolism prophylaxis regimens.

Design: A secondary analysis of patients enrolled in the ADAPT (A Different Approach to Preventing Thrombosis) randomized controlled trial.

Setting: Level I trauma center.

Open reduction and internal fixation alone versus open reduction and internal fixation plus total hip arthroplasty for displaced acetabular fractures in patients older than 60 years: A prospective clinical trial.

Introduction: The optimal treatment of elderly patients with an acetabular fracture is unknown. We conducted a prospective clinical trial to compare functional outcomes and reoperation rates in patients older than 60 years with acetabular fracture treated with open reduction and internal fixation (ORIF) alone versus ORIF plus concomitant total hip arthroplasty (ORIF + THA). Our hypothesis was that patients who had ORIF + THA would have better patient reported outcomes and lower reoperation rates postoperatively.

Pelvic Ring Injury Mortality: Are We Getting Better?

Objectives: To determine if changes in pelvic trauma care and treatment protocols have affected overall mortality rates after pelvic ring injury.

Design: Retrospective cohort study.

Setting: Level I trauma center.

Patient Satisfaction After Discharge Is Discordant With Reported Inpatient Experience.

Patient satisfaction measures are commonly used to evaluate clinical performance. However, research on the correlation between patient satisfaction scores and actual patient experience is limited. This study aimed to determine the concordance between patient satisfaction reported as an inpatient and patient satisfaction reported after discharge.

A Prospective Clinical Trial Comparing Surgical Fixation Versus Nonoperative Management of Minimally Displaced Complete Lateral Compression Pelvis Fractures.

Objective: To compare the early pain and functional outcomes of operative fixation versus nonoperative management for minimally displaced complete lateral compression (LC; OTA/AO 61-B1/B2) pelvic fractures.

Design: Prospective clinical trial.

Setting: Two academic trauma centers.

PREVENTion of CLots in Orthopaedic Trauma (PREVENT CLOT): a randomised pragmatic trial protocol comparing aspirin versus low-molecular-weight heparin for blood clot prevention in orthopaedic trauma patients.

Introduction: Patients who sustain orthopaedic trauma are at an increased risk of venous thromboembolism (VTE), including fatal pulmonary embolism (PE). Current guidelines recommend low-molecular-weight heparin (LMWH) for VTE prophylaxis in orthopaedic trauma patients. However, emerging literature in total joint arthroplasty patients suggests the potential clinical benefits of VTE prophylaxis with aspirin.

Acute total hip arthroplasty for older patients with acetabular fractures: A meta-analysis.

Objective: Multiple treatment options for acetabular fractures in geriatric patients exist. However, no large-scale studies have reported the outcomes of acute total hip arthroplasty (THA) in this patient population. We systematically evaluated all available evidence to characterize clinical outcomes, complications, and revisions of acute THA for acetabular fractures in geriatric patients.

A Calcar Collar Is Protective Against Early Torsional/Spiral Periprosthetic Femoral Fracture: A Paired Cadaveric Biomechanical Analysis.

Background: Periprosthetic fracture is a leading reason for readmission following total hip arthroplasty. Most of these fractures occur during the early postoperative period before bone ingrowth. Before ingrowth occurs, the femoral component can rotate relative to the femoral canal, causing a spiral fracture pattern.

Aspirin versus low-molecular-weight heparin for venous thromboembolism prophylaxis in orthopaedic trauma patients: A patient-centered randomized controlled trial.

Background: Emerging evidence suggests aspirin may be an effective venous thromboembolism (VTE) prophylaxis for orthopaedic trauma patients, with fewer bleeding complications. We used a patient-centered weighted composite outcome to globally evaluate aspirin versus low-molecular-weight heparin (LMWH) for VTE prevention in fracture patients.

Methods: We conducted an open-label randomized clinical trial of adult patients admitted to an academic trauma center with an operative extremity fracture, or a pelvis or acetabular fracture.

Quantitative Lesser Trochanter Profile Versus Cortical Step Sign in Assessing Femoral Malrotation After Femoral Nailing.

We describe the novel quantitative lesser trochanter profile (QLTP) technique to determine the magnitude and direction of femoral malrotation and to compare its performance with the cortical step sign technique. For this assessment, 9 orthopaedic surgeons estimated the magnitude and direction of femoral malrotation with each technique in 198 anteroposterior view images of the proximal cadaveric femur and osteotomy sites. Based on the results, the main benefit of the QLTP technique over the cortical step sign technique is the ability to determine the direction of femoral malrotation.

Posterolateral plating is a safe alternative for the treatment of distal tibial fractures.

Introduction: We assessed the outcome and safety of posterior plating of distal tibial fractures.

Methods: We conducted a retrospective case series at a Level I trauma center. Seventy-four consecutive patients with distal tibial fractures treated with anatomically contoured 3.

Predictors of Symptomatic Implant Removal After Open Reduction and Internal Fixation of Tibial Plateau Fractures: A Retrospective Case-Control Study.

A retrospective case-control study was conducted at a level I trauma center to assess whether radiographic details of tibial plateau fixation can predict symptomatic implant removal. Nine hundred fifty-one tibial plateau fractures were treated with open reduction and internal fixation from 2007 to 2016. Eighty-two (9%) were treated with implant removal for localized pain over the implant.

Initial experience with the T-Clamp for temporary fixation of mechanically and hemodynamically unstable pelvic ring injuries.

In polytrauma patients with unstable pelvic ring injuries, pelvic binders interfere with femoral arterial access and are frequently removed for emergent endovascular and abdominal procedures. The 'trochanteric C-clamp' (T-clamp) is a novel technique described for rapid stabilization of the pelvis without fluoroscopic imaging, while ensuring adequate access to the groin. This case series reports the feasibility and safety following T-clamp application for unstable pelvic ring injuries in patients requiring simultaneous endovascular intervention.

Periprosthetic Fractures and Conversion Hip Replacement Using the Direct Anterior Approach to the Hip.

Periprosthetic fractures of the femur and the acetabulum around a hip replacement are unfortunately relatively common as is failed acetabular and hip fracture fixation. This chapter will detail the use of the direct anterior approach to the hip to manage periprosthetic fractures of the femur and the acetabulum. We will also address the use of the direct anterior approach to the hip for conversion hip replacement in cases of failed femoral and acetabular fracture fixation.

Proximal Femoral Replacement Using the Direct Anterior Approach to the Hip.

Proximal femoral replacement is the salvage procedure for the most severe hip arthroplasty problems. We presented a straightforward approach to this complex procedure using the direct anterior approach to the hip. This allows for accurate fluoroscopic confirmation of acetabular implant placement and direct comparison of leg lengths.

Extensile Direct Anterior Approach to the Hip for Severe Acetabular Defects.

Although total hip arthroplasty (THA) surgery is one of the most successful procedures in orthopaedics, the number of revision procedures is predicted to increase by 137% over the next two decades. Implant failure modes such as instability, infection, loosening, and wear are becoming more prevalent. Instability, infection, extensive bony defects, and soft-tissue damage are the most important concerns and complications associated with revision surgery.
