Objective: To evaluate the clinical effect of bridge combined internal fixation system in the treatment of periprosthesis fracture of femur after hip replacement.
Methods: From October 2016 to June 2018, 5 patients of periprosthesis fractures of femur classified type B1 and type C in Vancouver were treated by open reduction and bridging combined with internal fixation, including 2 males and 3 females, with ages of 68, 70, 74, 75, 79 years;type B1 fractures in 4 and type C fractures in 1. Causes of injury:1 case of traffic injury, 4 cases of fall. After the operation, the patients were followed up for complications and fracture healing time by clinical and imaging examination, and Parker activity score was performed.
Results: The wounds of 5 patients healed without infection. One case of DVT was confirmed by venography. Five patients were followed up, and the durations were 2, 8, 9, 10, 15 months. One patient died of myocardial infarction 2 months after operation. The average healing time was 12.5 weeks. No loss of reduction or failure of internal fixation was found. Two patients could walk without protection and 1 patient needed to rely on single crutch. One case of periprosthetic fracture had to walk with a single crutch before operation and move indoors with two crutches after operation. The average Parker activity score was 51.8% before operation.
Conclusion: The bridge combined internal fixation system can be used to fix the fracture after hip replacement with stable femoral prosthesis.

Prior research has established that actions, such as eye movements, influence time perception. However, the relationship between pre-saccadic attention, which is often associated with eye movement, and subjective time perception is not explored. Our study examines the impact of pre-saccadic attention on the subjective experience of time during eye movements, particularly focusing on its influence on subjective time perception at the saccade target.

Introduction: The optimal management strategy for unstable distal clavicular fractures remains controversial. Recent studies on plate techniques have reported good-to-excellent outcomes with no serious complications. The questions are that: (1) Does the use of wire augmentation with locking plate in distal part (distal wire augmentation) reduce radiographic loss of reduction (RLOR) and get earlier bony union in distal clavicular fractures? (2) Which fixation methods are associated with a higher incidence of acromioclavicular (AC) joints arthritis or subluxation? We collected and analyzed clinical studies on different plate fixation methods for unstable fractures to identify the best surgical modality.

Purpose: Controversy remains about the ideal construct for certain olecranon fractures. The purpose of this study was to compare cost-effectiveness with the value driven outcomes tool between fixation strategies of olecranon fractures.
Methods: All surgically treated isolated proximal ulna fractures (CPT code 24,685) at a level 1 trauma center from 2013 to 2023 were retrospectively reviewed.

Background: Isolated distal fibula fractures (DFF) are usually treated with open reduction and internal fixation (ORIF) and non-weight-bearing protocols. The study assessed the outcomes of immediate weight-bearing on DFF healing and stability after lateral locking plating.
Materials And Methods: For this study, 49 patients affected by isolated DFF were enrolled.

Background: There is no consensus in the literature regarding the optimal treatment method for posterior pelvic ring injuries. This study aims to compare the radiologic and clinical outcomes, as well as complications of spinopelvic fixation (SPF) and iliosacral screw fixation (ISF) in patients with posterior pelvic ring injuries.
Methods: This retrospective study analyzed 54 patients (37 females, 17 males; mean age 38.
