Comparative StudyComparison of in vivo bioactivity and compressive strength of a novel superporous hydroxyapatite with beta-tricalcium phosphates.
Superporous hydroxyapatite (HAp-S) is a novel bone substitute that contains three-dimensionally interconnected macropores with micropores, which stimulate bone ingrowth into the material. ⋯ These findings should be kept in mind when choosing the highly porous ceramics.

Predictors of blood transfusion in patients undergoing elective surgery for degenerative conditions of the spine.
The requirement of blood in the surgery of degenerative conditions of lumbar spine is around 10 %. Preoperative autologous blood donation is an effective method that is used in surgeries with an important blood loss. This is an expensive method because of the great number of predonated blood units not used in the postoperative period (around 70 % in our practice). ⋯ Females, ASA 3, preoperative hemoglobin ≤136 g/L and age older than 60 years increase the risk to be transfused in the postoperative period for degenerative conditions of the spine.

The impact of coagulopathy on the outcome of traumatic epidural hematoma.
To evaluate the impact of trauma-associated coagulation disorders on the neurological outcome in patients with traumatic epidural hematoma undergoing surgical or non-surgical treatment. A retrospective analysis was performed using prospectively collected data in a consecutive patient series from a level 1 trauma center. ⋯ Poor outcome after traumatic epidural hematoma was associated with coagulopathy. Progression of epidural hematoma volume was not associated with coagulopathy or with poor neurological outcome. Prospective studies are needed to confirm these results.

Impaction bone grafting for femoral revision hip arthroplasty with Exeter Universal stem in Japan.
The purpose of the present study was to analyze the retrospective clinical and radiographic results of femoral revision arthroplasties with impaction bone grafting performed by experienced Japanese surgeons. ⋯ The present study showed encouraging mid-term results of impaction bone grafting for femoral revision arthroplasty by experienced surgeons in Japan. Aggressive augmentation of segmental defects and attenuated femoral shafts prevents massive stem subsidence and periprosthetic fracture.
