Prediction Value of SPECT/CT in Avascular Necrosis of Femoral Head After Femur Neck Fracture.

Introduction: The aim of this study was to determine the diagnostic value of single-photon emission computed tomography/computed tomography (SPECT/CT) in prediction of avascular necrosis (AVN) after femoral neck fracture and to evaluate whether photon defect in femoral head as seen in SPECT/CT can be an index for choice of surgical method.

Methods: This study was based on 97 patients who took SPECT/CT after femoral neck fracture from November 2012 to November 2017, with 64 patients with femoral intertrochanteric fracture in which chances of AVN is rare as a comparison group. Among 97 patients with femoral neck fracture, osteosynthesis was conducted in 7 patients with less than 15% of photon defect in damaged femoral head and 7 patients who wanted osteosynthesis, despite photon defect more than 15%, and 83 patients with photon defect more than 25% had arthroplasty.

Does Tranexamic Acid Increase the Incidence of Thromboembolism After Spinal Fusion Surgery?

Study Design: This was a retrospective analysis of prospectively collected data.

Objective: To investigate the incidence of thromboembolism in patients who received tranexamic acid (TXA) after lumbar spine fusion and determine the diagnostic value of lower limb duplex sonography as a screening test.

Summary Of Background Data: TXA is effective in reducing blood drainage in spine fusion surgery but some studies have reported increased incidence of venous thromboembolism associated with TXA.

Distal clavicle fracture treated with a titanium elastic nail (TEN).

It is generally known to use internal fixation using a hook plate or Kirschner wire as an operative treatment for distal clavicle fracture. TEN is a surgical technique that is mainly used in clavicle mid-shaft fracture, and there is no reported case for distal clavicle. We report a case of distal clavicle fracture treated with TEN.

Early Adjacent Vertebral Fractures after Balloon Kyphoplasty for Osteoporotic Vertebral Compression Fractures.

Study Design: Retrospective cohort study.

Purpose: To evaluate the incidence and risk factors for early adjacent vertebral fractures following balloon kyphoplasty (KP).

Overview Of Literature: KP is a safe and effective treatment for pain alleviation in patients with osteoporotic vertebral compression fractures (OVCF).

Clinical outcomes and survival rate of cementless modular distal fixation femoral stem for revision hip arthroplasty: A minimum 6-year follow-up.

Purpose: Revision hip arthroplasty is a very challenging procedure. Use of a modular distal fixation stem is one of the available options for revision arthroplasty in patients with proximal femoral bone deficiency. The purpose of this study was to evaluate mid- to long-term outcomes of cementless modular distal fixation femoral stem implantation in revision hip surgery.
