Case ReportsHip dislocation associated with ipsilateral femoral neck and shaft fractures: an unusual combination and dilemma regarding head preservation.
Traumatic posterior hip dislocation associated with a fracture of the femoral neck is a rare injury. The combination of posterior dislocation of the femoral head with ipsilateral femoral neck and shaft fractures is even rarer, with only one such case reported in literature. ⋯ The radiographs revealed union of all fractures without evidence of avascular necrosis of the femoral head at final follow-up of two years. This case is of particular interest as it highlights some of the important factors in deciding between head preservation versus arthroplasty for this complex fracture-dislocation.

Comparative StudyComparison of simultaneous bilateral with unilateral total knee arthroplasty.
The aim of this study was to compare simultaneous bilateral total knee arthroplasty (BTKA) and unilateral total knee arthroplasty (UTKA) in terms of morbidity, clinical and radiological findings and quality of life. ⋯ Simultaneous BTKA should be considered in selected patients under 70 years of age with good compliance and no comorbid disease.

Fixation of intertrochanteric femur fractures using Proximal Femoral Nail Antirotation (PFNA) in the lateral decubitus position without a traction table.
The aim of this study was to evaluate whether intertrochanteric femur fractures can be reduced and nailed properly in the lateral decubitus position using Proximal Femoral Nail Antirotation (PFNA) as a fixation device without the use of a traction table. ⋯ While the nailing of intertrochanteric fractures in a lateral decubitus position does not provide ideal quadrant placement and TAD, results are encouraging probably due to the excellent stability that is provided by PFNA.

Comparative StudyInfluence of number and orientation of screws on stability in the internal fixation of unstable femoral neck fractures.
The aim of this study was to biomechanically compare 3 different cannulated screw configurations used in internal fixation of unstable femoral neck fractures. ⋯ The use of a transverse screw in the calcar in addition to cannulated screws parallel to the neck appear to provide stability benefit in the treatment of unstable femoral neck fractures.

Comparative StudyEffects of bone drilling on local temperature and bone regeneration: an in vivo study.
The aim of this study was to examine the influence of bone drilling on local bone temperature and bone regeneration and determine optimal drilling speed and pressure in an animal model. ⋯ Our results suggested that lower drilling speed with higher pressure is necessary for better bone regeneration. The optimal drilling speed is 230 rpm and optimal drilling pressure 20 N.
