In an aging society, the number of femoral fractures is increasing, as well as the incidence of periprosthetic fractures. These secondary fractures are often difficult to fixate stably because of the osteoporotic bone and the existence of the former

Atypical femoral fractures (AFF) are more difficult to treat than typical femoral fractures; they require strong fixation and good reduction. Intramedullary (IM) nailing is the first option for the treatment of complete AFF; however, there are few re

Aside from cases of mechanical complications or infection short femoral nails (SFNs) are not removed after open reduction and internal fixation (ORIF) because femoral trochanteric fractures often occur in older osteoporotic females. Occasionally, SFN

The changes occurring in knee osteoarthritis often cause alterations in the spinal loading condition, which further lead to degenerative changes. This close relationship of the knee and spine has been reported as knee-spine syndrome. A 60-year-old wo

Implant fracture is one of the rarest complications of total hip arthroplasty (THA). A 57-year-old woman experienced a fracture of the femoral stem (AHFIX Q, KYOCERA, Japan) about five years after THA. We examined the broken stem by digital microscop

Recently, navigation systems have been more widely utilized in total hip arthroplasty. However, almost all of these systems have been developed for cementless cups. In the case of cemented total hip arthroplasty using a navigation system, a special-o

Purpose. Anderson type III odontoid fractures have traditionally been considered stable and treated conservatively. However, unstable cases with unfavorable results following conservative treatment have been reported. Methods. We present the cases of

Introduction Lag screw insertion into the ideal position is essential to obtain good results in open reduction and internal fixation for femoral trochanteric fracture. Tip-apex distance (TAD) is a widely adopted method for evaluating the risk of lag

We have demonstrated the high yield (∼900 µm) and highly single-wall selective (>95%) growth of carbon nanotube (CNT) forest using aluminium nitride (AlN) as a catalyst underlayer. Such high efficiency and single-wall selectivity have not been pre
