Background. The objective of this paper is efficacy assesment of partial bone resection procedure with subsequent joint exchange as a method of skeletal cancer metastases and pathological fractures surgical treatment within hip and shoulder among patients in our own experience.
Material and methods. 79 patients operated between 1997 and 2002 were assesed.Group I - 68 cases with sceletal cancer metastases and pathological fracture of proximal femur.Group II - 11 patients with sceletal cancer metastases and pathological fracture of humerus.The patients underwent primary or secondary (after complications) partial resection procedure with subsequent joint prosthesis implantation.The range of femur resection was 6-17cm.Various types of total or partial hip and shoulder joint endoprostheses according to indication were used.Additional paliative radiotherapy of mathastases,bisphosphonians and analgetics were used according to the case.The average follow-up period was 9,6 months (0-3y). The efficacy analysis was based on Enneking limb function test and Merle d'Aubigne classification and X-ray analysis in patients with partial proximal femur resection.
Results. Group I-according to Enneking test in 41 patients very good and good results,fair in 22 and bad only in 5 cases were found.According to Merle'd Aubigne classification in 37 cases very good and good outcome was found.In 25 the outcome was fair and bad in 6 patients.The machanical instability complication assesed radiologically were found in 7 patients.
Conclusions. The partial bone resection with subsequent joint exchange procedure is positively assesed in patients subjective opinion and its high rate of very good and good results let us conclude this kind of surgery as a very good method in some types of pathological fracture treatment.However a massive bone and particullary soft tissue resection may produce higher incidence of mechanical complications - especially dislocations.

Background: To analyze the effects of the positioning of a bolt in the femoral neck system (FNS) on the short-term outcomes of middle-aged and young adults with displaced femoral neck fractures (FNFs).
Methods: This was a retrospective study involving 114 middle-aged and young adults with displaced FNFs who were surgically treated with internal fixation via the FNS in the Department of Orthopedics, Suzhou Municipal Hospital, from December 2019 to January 2023. The degree of deviation of the central axis of the femoral head and neck from the tip of the bolt (W), the tip‒apex distance (TAD) and the length of femoral neck shortening (LFNS) were measured on postoperative X-ray and computed tomography (CT) scan images.
Periapical bone edema volume in 3D MRI is positively correlated with bone architecture changes.

Objectives: To compare and correlate bone edema volume detected by 3D-short-tau-inversion-recovery (STIR) sequence to osseous decay detected by a T1-based sequence and conventional panoramic radiography (OPT).
Materials And Methods: Patients with clinical evidence of apical periodontitis were included retrospectively and received OPT as well as MRI of the viscerocranium including a 3D-STIR and a 3D-T1 gradient echo sequence. Bone edema was visualized using the 3D-STIR sequence and periapical hard tissue changes were evaluated using the 3D-T1 sequence.

Pterosaur remains are rare from the lowermost Cretaceous, hampering our understanding of the taxonomic and morphological diversities of pterosaurs during this period. The Lower Cretaceous Tugulu Group in Wuerho, China is renowned for hosting the Wuerho Pterosaurian Fauna (WPF), which has so far yielded numerous fossil remains of two dsungaripterid pterosaurs, Dsungaripterus weii and Noripterus complicidens. Here we report a partial ornithocheiromorph humerus from the WPF, representing a deeply divergent clade from Dsungaripteridae.

Background: Eosinophilic esophagitis (EoE) is a chronic inflammatory disorder marked by eosinophilic infiltration of the esophageal mucosa. Despite advances in understanding and management, optimal therapeutic strategies remain unclear, with conflicting guidelines.
Objective: We sought to evaluate effectiveness and safety of topical corticosteroids (TCSs) and proton pump inhibitors (PPIs) in managing EoE and their economic implications in Italy.

Objective: Pulmonary involvement in chronic nonbacterial osteomyelitis (CNO) is rare. Limited awareness results in diagnostic challenges, especially because malignancy or infection needs to be considered.
Methods: Based on a survey shared among centers participating in the Kerndokumentation Deutsches Rheumaforschungszentrum (Germany), this study investigated clinical and imaging presentations, demographic features, treatment response and outcomes of pulmonary involvement in CNO (pCNO).
