AI Article Synopsis
- * A total of 55 patients were examined, divided into two groups based on their drilling technique: outside-in (Group A) and transportal (Group B), with CT scans taken at 1 week and 6 months post-surgery.
- * Results showed no significant difference in the rate of post-operative femoral tunnel communication between the two groups, though the mean distance of the bone bridge was greater in those without communication compared to those with.
Article Abstract
Purpose: The purpose of this study is to assess the incidence of post-operative femoral bone tunnel communication after anterior cruciate ligament double-bundle reconstruction (ACL-DBR) with two drilling techniques by transparent 3-dimensional computed tomography (CT) and elucidate the factors associated with post-operative femoral bone tunnel communication.
Methods: Fifty-five patients underwent ACL-DBR using outside-in technique (Group A, 25 patients) and transportal technique (Group B, 30 patients) for the drilling of femoral tunnel. CT was taken at 1 week and 6 months post-operatively. The femoral and tibial bone tunnel orientation, position, the divergency and the distance of bone bridge between the tunnels were measured using reconstructed CT images. In order to identify the factors related to post-operative femoral bone tunnel communication, patients were divided into two groups depending on whether femoral bone tunnels communicated (Group F-C) or remained (Group F-R) at 6 months post-operatively.
Results: Femoral bone tunnels in Group B were orientated horizontally and dorsally compared to those in Group A. Tunnel divergency between two femoral tunnels was greater in Group A (11.7°) than in Group B (10.0°). Average distance of bone bridge at 1 week post-operatively was 1.8 mm in Group A and 1.7 mm in Group B (n.s.). Post-operative femoral bone tunnel communication occurred in 16 patients (64 %) in Group A and in 18 patients (60 %) in Group B at 6 months after ACL-DBR, respectively (n.s.). Regarding tibial tunnels, there were no significant differences in tunnel orientation, position, divergency and incidence of post-operative tibial tunnel communication between Groups A and B. Mean distance of femoral bone bridge at 1 week in Group F-R (2.5 mm) was significantly greater than in Group F-C (1.3 mm) (p < 0.001).
Conclusions: There was no significant difference in the incidence of post-operative femoral tunnel communication between two techniques. To avoid post-operative femoral tunnel bone communication, more than 2 mm distance of bone bridge at surgery is recommended.

High Rate of Complications With Early Conversion Hip Arthroplasty Following Fracture Treatment.

Background: Conversion total hip arthroplasty (THA) is associated with higher rates of complications compared with primary THA, with prior surgical fixation of fractures in the ipsilateral hip shown to further increase these rates. There is a scarcity of literature on the effect of timing of conversion THA on complication rates. In this study, we evaluated early (≤6 months of index surgery) and late (>6 months of index surgery) conversion to THA following prior fixation of the proximal femur or acetabulum.

Objective: Abaloparatide (ABL) is a synthetic parathyroid hormone-related protein analog developed as an anabolic drug to treat osteoporosis. ABL increases bone mineral density (BMD) of the long bones and spine; however, the influence of ABL on alveolar bone regeneration remains unknown. This study assessed the effects of systemic ABL administration on tooth extraction socket healing and dental implant osseointegration in a preclinical rodent model.

Background: Hip morphology variations, particularly in femoral neck shaft angle (NSA) and iliac wing width (IWW), have been associated with gluteal tendinopathy. However, the biomechanical implications of these morphological differences on gluteal muscle function are not well understood. This study investigates how NSA and IWW influence gluteal muscle forces, moment arms, and estimated tendon loads during walking, aiming to provide insights into the potential biomechanical pathways that may contribute to altered lateral hip loading patterns.

Purpose: Simulation studies, such as finite element (FE) modeling, offer insights into knee joint biomechanics, which may not be achieved through experimental methods without direct involvement of patients. While generic FE models have been used to predict tissue biomechanics, they overlook variations in population-specific geometry, loading, and material properties. In contrast, subject-specific models account for these factors, delivering enhanced predictive precision but requiring significant effort and time for development.

Hypophosphatasia (HPP) is a congenital bone disease caused by tissue-nonspecific mutations in the alkaline phosphatase gene. It is classified into six types: severe perinatal, benign prenatal, infantile, pediatric, adult, and odonto. HPP with femoral hypoplasia on fetal ultrasonography, seizures, or early loss of primary teeth can be easily diagnosed.
