Chronic recurrent multifocal osteomyelitis (CRMO) is an extremely rare and most severe form of chronic nonbacterial osteomyelitis of unknown etiology. Here we present the first case of a six-year-old girl in which was observed that the stress fracture mimic osteomyelitic foci in the course of CRMO.

Objective: To evaluate the efficacy of supra-inguinal fascia iliaca compartment block (S-FICB) in patients undergoing proximal femoral nail antirotation (PFNA) internal fixation surgery for intertrochanteric fracture (ITF).
Methods: Retrospective analysis of 95 patients with ITF undergoing PFNA internal fixation surgery in the First People's Hospital of Yong Kang from March 2021 to August 2023 was performed. Among them, 49 patients received general anesthesia (GA; GA group) and 46 patients received S-FICB combined with general anesthesia (S-FICB group).

Developing hydrogels with high conductivity and toughness a facile strategy is important yet challenging. Herein, we proposed a new strategy to develop conductive hydrogels by growing metal dendrites. Water-soluble Sn ions were soaked into the gel and then converted to Sn dendrites an electrochemical reaction; the excessive Sn ions were finally removed by water dialysis, accompanied by dramatic shrinkage of the gel.

The most common type of proximal humerus fracture is surgical neck fracture. The purpose of this paper is to study the mechanical mechanism and the effect of bone degeneration on humeral surgical neck fractures. The right humerus finite element models were established based on CT computed tomography.

Objective: Reverse obliquity intertrochanteric fracture is an unstable type of fracture. Current guidelines recommend intramedullary fixation, but there are still complications such as screw removal, hip varus, nail withdrawal, and nail fracture. The objective of this study was to use finite element analysis to compare the biomechanical properties of the novel proximal femoral bionic nail (PFBN), proximal femoral nail antirotation (PFNA), and combined compression interlocking intramedullary nail (InterTan) in the treatment of reverse obliquity intertrochanteric fractures (AO/OTA 31-A3.

Background: The presence of mandibular third molars has been associated with the risk of mandibular fractures, highlighting the need for comprehensive studies considering the interaction with other mandibular structures. This study investigates how mandibular third molars and neighboring tissues can influence the structural fragility of the mandible using finite element analysis.
Material And Methods: A finite element analysis study following the guidelines proposed by RIFEM 1.
