Comparative Study
The application of open intramedullary fixation in the treatment of pediatric radial and ulnar shaft fractures.
This retrospective review evaluates the efficiency of standard intramedullary Kirschner wires for the treatment of unstable diaphyseal forearm fractures in children. ⋯ Intramedullary fixation is a useful technique for unstable shaft fractures of the forearm in children that can not be treated by closed manipulation.

Comparative Study
Indirect reduction and plating of distal femoral nonunions.
To observe and report the clinical results of indirect reduction and plating in the treatment of distal femoral nonunions. ⋯ Contemporary plating techniques are effective in the treatment of distal femoral nonunions. Union occurred reliably with few complications, resulting in a majority of good or excellent clinical results.

Comparative Study
Unipolar versus bipolar hemiarthroplasty: functional outcome after femoral neck fracture at a minimum of thirty-six months of follow-up.
This investigation was undertaken to compare a series of elderly individuals who sustained a displaced femoral neck fracture treated with either a cemented bipolar prosthesis or a cemented modular unipolar prosthesis. ⋯ Based on the results of this study, there does not appear to be any advantage to the use of a bipolar endoprosthesis in the management of displaced femoral neck fractures in the elderly. Furthermore, the extra cost of bipolar endoprostheses does not seem to warrant its use.

Comparative Study
A modified hip screw incorporating injected cement for the fixation of osteoporotic trochanteric fractures.
To evaluate a modified sliding hip screw for the fixation of trochanteric fractures that provides increased fixation strength in osteoporotic bones and allows for the safe intraoperative application of bone cement. ⋯ This modified hip screw augmented with bone cement can significantly enhance the initial fixation stability of trochanteric fractures in osteoporotic femurs.

Comparative Study
The effect of augmentation with resorbable or conventional bone cement on the holding strength for femoral neck fracture devices.
To compare maximum extraction torque and pull-out load for femoral neck fracture implants inserted with standard technique or after augmentation with polymethylmethacrylate (PMMA) or calcium phosphate cement (Norian SRS). ⋯ This study suggests that augmentation with PMMA around femoral neck fracture implants will increase the holding power significantly when compared with standard insertion technique as well as augmentation with calcium phosphate cement. Augmentation with calcium phosphate cement like SRS will increase the holding characteristics mainly in low density bone, whereas in high density bone it might even reduce the maximum torque because of the need for predrilling when using the cement for augmentation.
