TL;DR: Using the combination of these 3 antibiotics in the cement spacer for 2-stage reconstruction in infected hip arthroplasty when the causative organism is not identified in the culture of preoperative aspiration is recommended.

TL;DR: The results of this study suggest that the combination of marrow edema of the proximal femur and focal osteonecrosis of the femoral head are strongly associated with hip pain in early stage oste onecrosis, even prior to collapse.

TL;DR: Although lengthening over a nail can reduce the duration of external fixation, caution is required to prevent major complications.

TL;DR: With vascularized fibular grafting, careful monitoring of circulation and early intervention surgery is necessary to avoid vascular failure, and internal bone transport, repeated radical debridement until control of infection is achieved, bone grafting at the docking site for early union, and avoiding stress fracture are recommended to improve bone results.

TL;DR: It is suggested that a combination of varus derotation osteotomy and an acetabular procedure decreases the incidence of resubluxation or redislocation, and that unstable hips with > 70% uncoverage of the femoral head should undergo the combined procedure.
