ReviewCementless total hip arthroplasty in rheumatoid arthritis: a systematic review of the literature.
Compromised rheumatic bone is a potential risk factor for mechanical complications in cementless total hip arthroplasty (THA) in cases of rheumatoid arthritis (RA). Increased rates of intra-operative fractures, component migration and (early) aseptic loosening are to be expected. Despite this, cementless THA is performed in cases of RA. ⋯ Despite substantial rates of mechanical stem complications, no evidence was found to establish that cementless components perform less well than cemented components. The results justify the use of cementless THA in RA patients.

Survivorship of second-generation metal-on-metal primary total hip replacement.
Second generation metal-on-metal total hip replacements (THR) were introduced in the late 1980s and various studies reported conflicting data on their outcome. ⋯ As there was no superior probability of survival, and there have been concerns on putative local and systemic toxicity of metal debris, the use of second-generation metal-on-metal articulations for primary THR remains moot.

Randomized Controlled Trial Comparative StudyA comparative study on screw loosening in osteoporotic lumbar spine fusion between expandable and conventional pedicle screws.
The aim of this study is to compare the rate of screw loosening and clinical outcomes of expandable pedicle screws (EPS) with those of conventional pedicle screws (CPS) in patients treated for spinal stenosis (SS) combined with osteoporosis. ⋯ EPS can decrease the risk of screw loosening and achieve better fixation strength and clinical results in osteoporotic lumbar spine fusion.

Clinical TrialFall incidence and risk factors in patients after total knee arthroplasty.
To prospectively investigate the relationship between physical function and falls among elderly patients who underwent total knee arthroplasty (TKA) and to determine the incidence of falls as well as their risk factors. ⋯ Elderly people who underwent TKA are considered more likely to fall compared with healthy elderly people. For patients with limited knee flexion and ankle plantar flexion, improvement of ROM by exercise therapy and patient education regarding the prevention of falls and fractures are considered necessary.

Clinical TrialExtracorporeal shock wave therapy in early osteonecrosis of the femoral head: prospective clinical study with long-term follow-up.
Extracorporeal shock wave therapy (ESWT) may exert beneficial effects in avascular necrosis of femoral head (AVNFH). ⋯ ESWT in ARCO stages I and II may help to prevent progression of the area of avascular necrosis and manage pain.
