To evaluate the unreamed femoral nail with spiral blade (UFN-SB) in the treatment of nonpathologic subtrochanteric and segmental femoral fractures. ⋯ There is predictive value of the Seinsheimer classification as to outcome using UFN-SB. The UFN-SB is an option for the treatment of subtrochanteric or segmental fractures of the femur, especially in patients with a good quality of bone. The complications using this device are not caused by the learning curve, but by the characteristics of the implant and the type of fracture for which it is used. The implant should not be used in elderly women with a reversed oblique fracture or a subtrochanteric fracture with an intertrochanteric component.

To determine the biomechanical characteristics of four different fixation constructs for split depression fractures of the lateral tibial plateau (OTA classification 41B3.1). ⋯ There was no significant difference in the overall construct stiffness between the four fixation constructs. Fixation constructs with a raft of subchondral screws were more resistant to local depression loads. This supports the use of a raft construct when a central depression is a significant component of the overall fracture pattern. Condylar tilt data showed a persistent weakness in the postfixation lateral plateau regardless of fixation construct when compared with the intact specimen. This supports the current clinical practice of delayed weight-bearing for ten to twelve weeks.

Comparative Study
Migration of the lag screw within the femoral head: a comparison of the intramedullary hip screw and the Gamma Asia-Pacific nail.
To study the functional difference in the performances of sliding femoral head screws by comparing the displacement of the screw in relation to the femoral head in hips treated with the Gamma Asia-Pacific nail (GN) and hips treated with the intramedullary hip screw (IMHS). ⋯ These results indicate that the displacement of the femoral head screw of the IMHS was less than the lag screw of the GN. However, it is still unknown whether this smaller displacement of the IMHS is clinically significant for reducing the rate of screw cut-out after surgery.

Comparative Study
Comparison between clinical and radiologic outcome measures after reconstruction of acetabular fractures.
To compare clinical and radiologic outcome measures in patients after reconstruction of acetabular fractures and to investigate whether an objective radiologic outcome could be used as a proxy for a clinical outcome. ⋯ The Merle d'Aubigné score has shortcomings as an outcome measure for acetabular fractures. Our aim to use a radiologic outcome as a proxy for this clinical grading system was not realized, but we propose that the patient's walking ability could be used as an objective local outcome measurement.
