Objectives: We evaluated the results of reamed and locked intramedullary nailing for tibial diaphysis fractures.
Methods: The study included 73 patients (68 males, 5 females; mean age 31 years; range 17 to 68 years) who were treated with reamed and locked intramedullary nailing for tibial diaphysis fractures. There were 28 AO/ASIF type A, 29 type B, and 16 type C fractures. The fractures involved the proximal 1/3 (n=12), middle 1/3 (n=50), and distal 1/3 (n=11) of the tibial diaphysis. Twenty-eight fractures (38.4%) were closed. According to the Gustilo-Anderson classification, 30 patients (41.1%) had grade I, 10 patients (13.7%) had grade II, and five patients (6.9%) had grade IIIA open fractures. Intramedullary nailing was performed following open reduction in 17 patients (23.3%), and closed reduction in 56 patients (76.7%). The mean time to surgery was 3.4 days (range 2 to 11 days) and the mean follow-up was 48 months (range 24 to 60 months). The patients were evaluated with respect to range of motion, time to union, and complications. Functional results were assessed using the Johner-Wrush criteria.
Results: Union was achieved in all the patients within a mean of 18.2 weeks (range 8 to 52 weeks). Four patients required dynamization because of delayed union and grafting was performed in one patient. Transient sensorial deficit occurred in one patient after dynamization. One patient underwent revision surgery because of migration of the distal locking screws. The only limitation of range of motion was seen in flexion of two patients (2.7%) who developed anterior knee pain. According to the Johner-Wrush criteria, functional results were very good in 45 patients (61.6%), and good in 28 patients (38.4%).
Conclusion: Treatment of tibial diaphysis fractures with reamed and locked intramedullary nailing is an appropriate choice with a low complication rate. It can be safely used in moderately contaminated open fractures.

Objectives: Hydroxyapatite (HAp)/collagen (Col) cylinders with laminated collagen layers were implanted into the tibial diaphysis of rats and examined histochemically to clarify how the orientation of HAp and Col bone-like nanocomposite fibers in HAp/Col blocks affects bone resorption and formation.
Methods: HAp/Col fibers were synthesized and compressed into cylindrical blocks to mimic bone nanostructures. These were implanted into the cortical bone cavities of 10-week-old male Wistar rats with fiber bundles parallel to the tibial surface.
Purpose: Tibial rotational deformity is a known risk factor for patellofemoral joint (PFJ) disorders. However, it is commonly associated with other abnormalities which affect the PFJ. The purpose of this study was to describe the prevalence of associated factors known to affect PFJ in patients undergoing rotational tibial osteotomy and their implication for the correction level.

Purpose: High Fascial Compartment Pressure (HCP) is one of the most common complications in ankle fractures. This study aimed to investigate the incidence of HCP in pilon fracture and analyze the risk factors of HCP in order to closely monitor its further development into Acute Compartment Syndrome. A nomogram is constructed and validated to predict HCP in patients with pilon fracture.

Objective: This study aimed to assess the effect of implantation of fresh human amniotic membranes (HAM) on bone consolidation during distraction bone lengthening.
Methods: Ten New Zealand white rabbits were used in this study. For each rabbit, we performed a diaphyseal tibial osteotomy after installing a single-plane distraction external fixator.
