Method of computer modeling of behavior of cylindrical and lamellar bones under the hypervelocity impact is suggested. This method allows in the frame of mechanics of continuous medium to calculate the stress strain behavior and damage in bone tissues under the shock wave impact. The processes of shock correlation of steel fragments of different shape with diaphysis of cylindrical bones and flat bone of calvaria under the impact 500 m/s are studied. The given method can be used for the evaluation of damage area of bone tissue of shock wave osteoporosis under the gunshot wound.

The urgent etiological diagnosis represents the main management objective of cervical spondylodiscitis (CSD) to start as soon as possible antibiotic treatment to prevent neurological deterioration. The present study aimed to evaluate a multicenter experience implementing a minimally invasive surgical approach (MISA) to manage CSD such pathology vs the most complex and aggressive surgical strategies currently used.This retrospective multicenter study used a database of 70 patients from five European neurosurgical centers.

Pulmonary fibrosis is a pathological manifestation that occurs upon lung injury and subsequence aberrant repair with poor prognosis. However, current treatment is limited and does not distinguish different disease stages. Here, we aimed to study the differential functions of Axl, a receptor tyrosine kinase expressing on both macrophages and fibroblasts, in the whole course of pulmonary fibrosis.

Background: Cervical radiculopathy is caused by dysfunction of nerve roots in the cervical spine. While many studies have assessed the effectiveness of interlaminar epidural steroid injection (ILESI) and stabilisation exercises separately for this condition, our study aims to evaluate the impact of different stabilisation exercise programmes following ILESI on treatment outcomes in radiculopathy patients.
Methods: Sixty-two patients with cervical radiculopathy were randomised into three groups: cervical ILESI-only (CO), neck stabilisation group (NSG) and scapular stabilisation group (SSG).

Introduction And Aims: Implantation of the posterior maxilla with insufficient bone height faces challenges. Studies have shown that the use of ultrashort implants can avoid additional damage. This finite element analysis study aimed to evaluate the impacts of different lengths of ultrashort implants and three surgical approaches on stress, strain, and displacement in the posterior maxilla with varying bone heights.
