- Our aim was to compare hemiarthroplasty (HA) and osteosynthesis (OS) in the treatment of cervical hip fractures using matched-pair analysis, especially with regard to different age groups. Data concerning all hip fractures (excluding pathological fractures) at the University Hospitals of Lund in Sweden, where osteosynthesis with LIH hook-pins was used exclusively, and of Oulu in Finland, using mainly cementless Austin-Moore hemiarthroplasty, were registered during 1989-1996 using the same standardized hip fracture forms filled in preoperatively and at 4 months follow-up. Altogether 446 pairs matched for age, sex, place of residence and walking ability at the time of fracture were found. Patients aged 55-80 years seemed to benefit more, with regard to function, from OS than older patients. At 4 months follow-up, 38% of HA and 48% of OS patients lived in their own homes, 16% and 27% were able to walk alone outdoors, and 11% versus 16% were able to walk without any aids, respectively. At I year follow-up, mortality was significantly lower among the OS patients, but the reoperation rate was significantly higher. In conclusion, OS is associated with a better function and lower mortality than HA, especially in younger patients, and it is recommended as the primary treatment for cervical hip fractures in patients younger than 80 years and with good ambulatory capacity, whereas the oldest patients can also be safely treated by HA.

- This paper summarizes the recent work on JET in the three areas of heating, current drive and energetic particles. The achievements have extended the possibilities of JET, have a direct connection to ITER operation and provide new and interesting physics. Toroidal rotation profiles of plasmas heated far off axis with little or no refuelling or momentum input are hollow with only small differences on whether the power deposition is located on the low field side or on the high field side. With LH current drive the magnetic shear was varied from slightly positive to negative. The improved coupling (through the use of plasma shaping and CD4) allowed up to 3.4 MW of PLH in internal transport barrier (ITB) plasmas with more than 15 MW of combined NBI and ICRF heating. The q-profile with negative magnetic shear and the ITB could be maintained for the duration of the high heating pulse (8 s). Fast ions have been produced in JET with ICRF to simulate alpha particles: by using third harmonic He-4 heating, beam injected He-4 at 120 kV were accelerated to energies above 2 MeV taking advantage of the unique capability of JET to use NBI with 4 He and to confine MeV class ions. ICRF heating was used to replicate the dynamics of alpha heating and the control of an equivalent Q = 10 `burn' was simulated.

- Osteosynthesis (OS) and hemiarthroplasty (RA) are the commonest treatments for displaced cervical hip fractures in the elderly, but there is no consensus as to which is better. In this prospective matched-pair study we compared these methods as regards functional outcome. In 1989-1996, using the same standardized forms, all displaced cervical hip fractures were prospectively registered in the university hospitals of Oulu in Finland and Lund in Sweden. Osteosynthesis was performed in Lund and hemiarthroplasty in Oulu. Cross-matching, done for age, sex, preoperative residence, and ambulatory ability, resulted in 357 pairs of displaced fractures. More OS than HA patients could manage in their own homes or live semi-independently at 4 months after the fracture. OS patients had better ambulatory ability (p = 0.001) and used walking aids less than HA ones (p = 0.001). The reoperation rates at 4 months were the same among HA and OS patients, but at 1 year, OS patients had a higher reoperation rate (17%) than HA ones (9.5%).
