Pelvic fractures are among the most complex challenges in orthopedic trauma, which usually involve hipbone and sacrum fractures, as well as joint dislocations. Traditional preoperative surgical planning relies on the operator's subjective interpretation of CT images, which is both time-consuming and prone to inaccuracies. This study introduces an automated preoperative planning solution for pelvic fracture reduction, addressing the limitations of conventional methods.

This review aimed to provide a comprehensive analysis of the etiology, epidemiology, pathology, and conventional treatment of heterotopic ossification (HO), especially emerging potential therapies. HO is the process of ectopic bone formation at non-skeletal sites. HO can be subdivided into two major forms, acquired and hereditary, with acquired HO predominating.

- Displaced fragility fractures of the pelvis (FFP) present major challenges in orthopedic trauma, especially in older patients with weak bones and other health issues, but no robotic solutions have been documented for managing these fractures.
- A study evaluated a new robot-assisted fracture reduction system on 15 elderly patients, achieving a 100% success rate in fracture reduction and excellent recovery scores after 6 months.
- The innovative system enhances surgical precision and effectiveness, potentially transforming the treatment of FFP in an aging population by addressing the complexities associated with traditional methods.
Article Synopsis
- * Results show that the group using TCC had a higher rate of excellent and good fracture reduction (100%) compared to the control group (92.6%), and they experienced less varus angle loss and shorter recovery time for full weight-bearing.
- * However, TCC patients had significantly higher intraoperative blood loss, while no significant differences were found in Harris scores or survival rates between the two groups, suggesting TCC may enhance treatment efficacy despite the increased
This paper focuses on achieving pathwise synchronization in stochastic differential equations with linear multiplicative rough noises, which are fractional Brownian rough paths with Hurst parameter H∈(13,12). Using rough paths theory, a useful transformation is introduced to convert the equations into random differential equations. Stability and dynamical behavior of the solutions to the equations are discussed, and pathwise synchronization of the solutions to the coupled system is proven.

- - The study explored the use of a robot-assisted fracture reduction (RAFR) system for minimally invasive treatment of unstable pelvic fractures, focusing on its indications, safety, and effectiveness.
- - A total of 22 patients were treated using the RAFR system, which utilizes preoperative 3D CT scans to intelligently plan and execute the optimal reduction of fractures, leading to successful outcomes.
- - Results showed a minimal average error in fracture reduction (3.41mm) and high patient satisfaction, with 95.5% of cases rated as excellent or good based on the Matta criteria.
Background: Numerous treatment strategies have been reported for the treatment of chronic frank distal tibiofibular syndesmosis instability, including several small case series treated by syndesmosis arthrodesis. The aim of this study is to report the treatment of this condition using a specially contoured plate and the associated clinical outcomes.
Methods: Over a period of 8 years, patients presented in our institution with chronic frank distal tibiofibular syndesmosis instability were eligible to participate.

In some circumstances (such as in developing countries or in acute trauma), accurate computed tomography (CT) 3D reconstructions are difficult to obtain and plain radiography must be relied upon for surgical planning. Therefore, a simulation model of pelvic displacement was evaluated as a basis for improving the assessment of pelvic fracture displacement from plain radiography images.

- The study aimed to assess the effectiveness of surgically removing severe heterotopic ossification (HO) in patients who had surgery for acetabular fractures, focusing on their functional recovery as measured by the Harris hip score (HHS).
- A retrospective review involved 18 patients, predominantly male, who underwent HO resection, with their average age being approximately 36.8 years and a follow-up period of about 4.5 years after the procedure.
- Results showed a mean HHS of 84.5, indicating mostly positive outcomes, but also highlighted complications like mild HO recurrence in 33.3% of cases, with varying rates based on the timing of the resection.
Background: Surgical treatment of acetabular fracture has long been a challenging area in the field of orthopedic trauma. The aim of this research was to investigate the operative methods for delayed acetabular fractures and to assess the operation results.
Methods: The operative approaches, procedures, results, and complications of the delayed acetabular fractures between 1995 and 2005 were retrospectively evaluated at Beijing Jishuitan Hospital.
Objectives: To discuss the diagnosis and differential diagnosis, and to establish an effective protocol to treat the posterior Monteggia fracture-dislocations of proximal ulna in adult according to our experience.
Methods: Between April 2004 and December 2007, 16 patients with posterior Monteggia fracture-dislocations were treated surgically, 13 were followed up at a mean of 28 months (range, 12 - 58 months). All the operations were through the posterior midline approach.
Objective: To report the clinical experience in trans-sacroiliac joint with plate via the anterior approach in management of posterior pelvic injuries.
Methods: The clinical data of 29 cases (30 sides) with pelvic injury, 16 being of type B, and 13 of type C according to the Tile classification; with the average displacement of the posterior ring injuries of 18 mm; undergoing trans-sacroiliac joint with plate via the anterior approach from January 2002 to June 2007 were analyzed retrospectively, among which 20 sides were fixed by two plates across the sacroiliac joint and 10 sides by single plate. The anterior pelvic injuries of 22 cases were fixed by plates too.

Objective: To study the clinical significance of computed tomography (CT) in diagnosis and treatment of acetabular fractures.
Methods: The plain and CT films of the 66 cases of acetabular fracture from January 2001 to June 2002 were analyzed retrospectively, and the radiological characteristics and results were compared to each other.
Results: The diagnosis of 6 cases were changed after CT examination, and the occurrence ratio of marginal impaction, free body in joint, femoral head fracture, sacro-iliac injury and ischial tubersoity fracture involvement were 3:17, 7:29, 6:15, 0:5 and 1:5 in plain and CT examination respectively.
Objective: To improve the effect of operative management of acetabular fractures.
Methods: One hundred and seventy eight acetabular fractures were treated operatively from August 1993 to December 2000. Their functional results and complications were analyzed.
Objective: To understand the diagnosis and treatment of marginal impaction of acetabular fractures.
Method: Eighteen of 26 patients with marginal impaction of acetabular fractures were retrospectively reviewed. Marginal impactions was confirmed in 15 patients by CT scan before operation, and in 3 during operation.
Objective: To assess the operative methods of delayed acetabular fractures and the operative results.
Methods: The operative approaches, procedures, results and complications of the delayed acetabular fractures between August 1993 and August 2001 in Jishuitan Hospital were evaluated retrospectively.
Results: Thirty-two patients were followed up 49.
