The aim of this study was to determine the rate of complications after routine syndesmotic screw removal. ⋯ There were 5% wound infections after routine syndesmotic screw removal. Routine antibiotic prophylaxis effective against S. aureus should be administered when removing syndesmotic screws. In our institution we now use one single dose Cefalotin of 2g intravenously 30-60min before screw removal.

The aim of every patient with hip fracture is to regain previous function but we know little about the outcome, especially patient-reported outcome. We wanted to investigate what factors influence the result one year after hip fracture, including fast-track for hip fracture patients, as well as investigating the patients' satisfaction with their rehabilitation and to what degree they regained their pre-fracture function. ⋯ General complications seem to be the major risk factor, being the only factor affecting functional outcome and together with local complications affecting pain and satisfaction. To avoid general complications, co-operation between orthopaedic surgeons and internists may be crucial in the aftercare of hip fracture patients. A majority did not receive adequate rehabilitation and efforts need to be made to improve the rehabilitation process.

The importance of the periosteum in fracture healing is well-known. Preserving periosteal vascularisation is essential during internal plate fixation of fractures. ⋯ The results show that plates with lower contact surface area stimulate angiogenesis in the underlying periosteum, which results in much higher blood vessel density compared with standard DCP. A randomised clinical trial is needed to prove the clinical relevance of these findings.

In this study, we tested the effect of Teriparatide (PTH) in combination with β-tricalcium phosphate (β-TCP) as a bone void filler in an ovariectomised rat distal femoral metaphysis model.β-TCP is a completely resorbable synthetic calcium phosphate and the Teriparatide is a drug that can promote bone formation in the condition of osteoporosis. A critical size defect of 3mm in diameter, a through-hole bone defect, was drilled into each distal femur of the ovariectomised rats. The hole was filled with β-TCP and the rat was injected PTH Teriparatide (30μg/kg) in peritoneum 5 times per week. ⋯ In total, 60 animals were investigated. When the β-TCP and PTH were used, histological, biochemistry and histomor-phometric evaluations revealed significantly better bone healing in terms of quantity and quality of the newly formed bone. The Ovariectomised rats which suffer from femur metaphysis defect are cured by embedding β-tricalcuim phosphate and intermittently cured by parathyroid hormone (PTH).

The bone healing process is very complex. In simple terms, bone healing comprises three basic steps, the inflammation phase, the repair phase and the remodelling phase. The increase in blood flow around the fracture during the healing process increases the temperature of the surrounding tissue. Infrared thermography is a method of measuring body temperature that can detect temperature changes during bone healing. Studies on the application of thermography in traumatology are scarce, and there are no studies of thermal changes during normal bone healing. The authors have tried to determine the dynamics of thermal changes during bone healing. ⋯ Preliminary findings during this research showed significant temperature changes during healing of distal radius fractures. Infrared thermography is a simple and reliable method in clinical practice that could be used as a good follow-up method in traumatology, but further investigations on more patients are needed.
