Skeletal Manifestations of Gaucher's Disease: A Case Report and Literature Review.
Semin Musculoskelet Radiol
August 2024
Gaucher's disease (GD) is a lysosomal storage disorder characterized by the storage of glucosylceramide in macrophages ("Gaucher cells"), mainly in the reticuloendothelial system. GD type 1 (GD1) is the most common phenotype that usually manifests with hepatosplenomegaly, cytopenias, and bone involvement. Skeletal manifestations are the most debilitating characteristic and result in significant morbidities.

- The Birmingham Hip Resurfacing (BHR) technique was developed in 1997 to cater to young, active patients, showing effective survival rates even after 25 years of follow-up on the original 130 patient cohort.
- Overall implant survival reached 83.5% at 25 years, with male patients faring better (89.5%) compared to females (66.9%), while failures were primarily due to metal debris reactions and femoral neck fractures.
- The study concludes that BHR offers a lasting alternative to total hip arthroplasty, especially beneficial for younger patients needing hip replacement.*
Introduction: Non-autoimmune sacroiliac joint pain contributes to nearly a quarter of low back pain patients. Non-surgical management fails to satisfy patients. A new minimally invasive technique for sacroiliac stabilization has been introduced, defying the traditional rules of fusion.

Purpose: The study proposed a simple classification system that aimed at predicting the labral procedure during hip arthroscopy using images from unenhanced 3T MRI scans.
Patents And Methods: Forty patients undergoing hip arthroscopy had their MRI scans reviewed pre-operatively by one of two senior radiologists and classified into: type 1: stable labrum with intra-substance degeneration (no labral repair required), type 2: unstable labrum, no intra-substance degeneration (labral repair required), or type 3: unstable labrum with intra-substance degeneration (Labral repair not feasible). Hip arthroscopy is carried out by one of two surgeons and classified accordingly while blinded to the radiologists' assessment.
Introduction: and aim: Traumatic peri-prosthetic fractures are relatively rare fractures that pose a significant surgical challenge. They have a fracture pattern that is different from its iatrogenic counterpart. This study aimed at reviewing the modalities of treatment of such injuries, proposing a treatment algorithm and reporting the outcomes of these injuries.

The aim of this study was to evaluate a protocol using LMWH prophylaxis and duplex screening both pre-operatively (if there is a delay > 72 h to surgery) and post-operatively at day 5-7. We assessed the incidence of thromboembolism and associated risk factors.

CT scan may provide more accurate detail regarding metalwork position, retained intra-articular fragments, and quality of reduction but does expose the patient to additional radiation dosage and incurs increased cost. The aim of this study was to evaluate a protocol of routine postoperative CT scan for all acetabular fractures after surgical fixation and assess the effect this has on patient management.

- The study aimed to compare the effectiveness of two fixation methods—posterior plating alone and posterior plating with anterior column lag-screw fixation—for treating transverse acetabular fractures.
- Thirty patients participated in a randomized trial, with assessments focusing on fracture stability through radiographic evaluations and clinical outcomes over a follow-up period of about 19 months.
- Results indicated no significant differences in outcomes between the two groups, suggesting that single posterior column fixation is as effective as double column fixation for these types of fractures.
Introduction: There is no consensus regarding the postoperative radiology imaging protocol after pelvic fracture surgery. Some institutes routinely scan all patients after their surgery, others do not. The aim of this study was to assess the value of routine use of computed tomography (CT) scans after pelvic fracture surgery and to determine the sensitivity of conventional plain radiographs and intraoperative fluoroscopy in detecting metalwork malposition.

- The study aims to define and classify quadrilateral plate (QLP) fractures, as there is currently no existing system for these injuries.
- The research involved anatomical analysis using pelvic specimens and a review of CT images from 609 patients with acetabular fractures to identify radiological landmarks related to QLP fractures.
- The resulting classification system categorizes QLP fractures into four types based on the degree of separation and complexity, potentially aiding in future identification and treatment strategies.

- The study aimed to compare the effectiveness of two surgical techniques, crossed and lateral pin configurations, for treating supracondylar humeral fractures in children by junior trainees.
- Involving 60 children with an average age of 5.1 years, results showed that the crossed configuration was more stable, with 0% complications, while 20% of the lateral cases had stability issues.
- Findings indicated that the crossed pin method is significantly better for stability and safety, with statistical evidence supporting its efficacy for junior surgeons.
