Total hip arthroplasty following acetabular fracture: a clinical and radiographic outcome analysis of 67 patients.
Total hip arthroplasty (THA) is a challenging option for the treatment of posttraumatic arthritis due to acetabular fractures. ⋯ The decrease of the interval between injury and arthroplasty was associated with increasing patient age (p = 0.001) and surgical treatment of the acetabular fracture (p = 0.04). Complex fracture patterns were accompanied by acetabular bone defects more often than simple patterns (p = 0.03). Overall, arthroplasty due to posttraumatic osteoarthritis after acetabular fracture resulted in decreased overall survival rates and poorer clinical outcome as compared to primary arthroplasty.

The entry point of intramedullary tibia cutting guide should vary according to the individual tibia morphology in TKA.
In total knee arthroplasty (TKA) using the intramedullary tibial cutting guide (IMTCG), the positioning of the IMTCG is important for accurate tibial bone resection. The aim of this study was to evaluate the ideal entry point of IMTCG and affecting radiologic factors. ⋯ The ideal entry point of IMTCG should vary according to the individual tibial morphology.

Pedobarographic changes during first month after subtalar extra-articular screw arthroereisis (SESA) operation of juvenile flexible flatfoot.
Juvenile flexible flatfoot deformity is a common problem in childhood. In severe cases, the subtalar extra-articular screw arthroereisis (SESA) according to De Pellegrin is a viable and effective option. There are just a few retrospective studies showing long-term outcomes, but the interval right after the surgery has not been described so far, even though the short time of healing is one of the great benefits of this technique. In this study, we examined if the pedobarographic measurements are able to demonstrate functional changes in the month after surgery. ⋯ During bipedal stance, the ground force increased significantly in lateral foot areas (p < 0.001) and decreased in medial areas (p < 0.001). While the force in the medial midfoot remained reduced, in the medial forefoot, the force increased 14 days after surgery (p < 0.05) CONCLUSION: The functional changes after SESA can be accurately assessed using pedobarography. The results indicate morphologic changes of the foot, in particular the development of a longitudinal arch. Post-surgical progression can be monitored and success of the surgery can be verified.

Corrective osteotomies of femur and tibia: which factors influence bone healing?
Corrective osteotomies of the lower limb are standard procedures in orthopedic surgery. Still, there is only limited research on factors affecting bone healing after osteotomies. We hypothesize that especially the location of the osteotomy, smoking status and BMI affect bone healing. ⋯ Smoking status and the localization of the osteotomy on femur and tibia (diaphysis vs. metaphysis) are significantly correlated with bone healing duration. In line with current literature emphasizing the detrimental effect of smoking on bone healing, our findings should encourage surgeons to think twice about the indication to perform osteotomies on smokers. Furthermore, if applicable, osteotomies should be performed in the metaphyseal areas of femur and tibia.

Analysis of computed tomography-based infra-acetabular morphometry to assess the feasibility of infra-acetabular screws.
The number of pelvic fractures based on osteoporosis has been increasing. The infra-acetabular screw (IAS), which connected both osseous columns, is a safe method of screw placement going through the infra-acetabular corridor (IAC). However, the specifics of the anatomy of IAC have been far from completely understood, especially in the Asian population. The purpose of our study was to reveal the details of the IAC using computed tomography (CT) data. ⋯ Surgeons should pay attention to the fact that over 20% of IACs are not feasible for infra-acetabular screw placement even with the perfect reduction of fragments when treating acetabular fractures.
