Objectives: This study aims to investigate the clinical application values of percutaneous kyphoplasty (PKP) under the guidance of DynaCT in the treatment of compression fractures of thoracolumbar.
Methods: 57 patients with compression fractures of thoracolumbar who were treated with PKP in The Second People's Hospital of Weifang from December 2014 to August 2016 were selected. Patients were randomly divided into DynaCT+DSA treatment group (27 cases) and DSA treatment group (30 cases) for PKP surgery. There were 19 cases of simple thoracic compression fractures, 28 cases of simple lumbar compression fractures, and 10 cases of thoracic vertebral compression fractures. Bone cement filling and leakage conditions were recorded after surgery. Efficacy of PKP was evaluated at 3 days after operation using visual analogue scale (VAS) and the maximal depth of the affected vertebrae. 71 lesioned vertebrae were treated and all punctures were successful.
Results: VAS score and height of the largest depression in vertebrae were significantly improved after surgery (p<0.05), while no significant differences were found between 2 groups. The leakage rate of bone cement in the two groups was 24.3% and 18.4%, respectively.
Conclusion: DynaCT can be used to guide the development of vertebral puncture program before PKP, guide the accurate puncture during operation, and can be used to evaluate the leakage of bone cement timely and reliably.

Purpose: There is a growing interest in using computed tomography (CT) scans to opportunistically assess bone mineral density via Hounsfield units (HU). Previous studies have shown lower HU in patients with vertebral compression fractures (VCFs) and that HU can predict pre-existing VCFs. This study evaluated whether HU from CT scans can predict the number of prevalent VCFs.

Osteoporotic vertebral compression fractures (OVCFs) can be painful. Percutaneous kyphoplasty (PKP) aims at strengthening the vertebra and reducing pain, but efficacy can vary among patients. The purpose of this study was to establish a risk prediction model for pain relief following PKP in patients with OVCF.

Introduction: Posterior cruciate ligament (PCL) avulsion fractures of the tibia with ipsilateral tibial shaft represent a rare but challenging orthopedic injury, necessitating careful consideration of surgical interventions for optimal outcomes. This case report presents the successful management of tibial shaft fracture (proximal 1/3rd junction) along with ipsilateral PCL avulsion fracture of tibia using a novel approach using open reduction internal fixation (ORIF) of tibial shaft with Locking compression plate (LCP) with cannulated cancellous screw and spiked washer fixation of PCL avulsion. There are no case reports or research articles available for the management of PCL avulsion fracture of tibia associated with ipsilateral tibial shaft fracture.

Objective: To report the outcomes of transoral C2 osteotomy (or partial odontoidectomy) and posterior fixation, regarding efficacy and safety, in patients with severe irreducible atlantoaxial dislocation (IAAD) following odontoid fracture.
Methods: Transoral C2 osteotomy, soft tissue resection, with or without facet joint release, followed by posterior fixation were performed on 3 patients (2012, 2016, 2023) who were suffering from severe IAAD after an odontoid fracture with spinal cord compression. The radiological and clinical outcomes were then assessed.

Background: Rib and sternum fractures are common injuries associated with cardiopulmonary resuscitation (CPR). The fracture mechanism is either direct by application of force on sternum and anterior ribs or indirect by bending through compression of the thorax. The aim of this study was to determine morphologies of rib fractures after CPR and to reevaluate prior findings on fracture localisation, type and degree of dislocation.
