Three-year results of proximal tibia fractures treated with the LISS.

Unlabelled: Proximal tibia fractures present a difficult treatment challenge with historically high complication rates. In a prospective study, we asked whether the Less Invasive Stabilization System (LISS) plate can adequately treat extraarticular and complex intraarticular proximal tibia fractures and provide low complication rates and acceptable long-term functional outcomes. We prospectively observed 25 patients with 26 proximal tibia fractures (AO type A2, A3, C1, C2, or C3) treated with the LISS.

A new locking plate for unstable fractures of the proximal humerus.

Unlabelled: In a prospective study, 28 patients with 29 proximal humeral fractures were treated with the Locking Proximal Humerus Plate from 2001-2002. Most of these fractures were complex, Type B (n = 15) and Type C (n = 9) fractures, according to the AO classification. Followups included radiographs, clinical examinations, and recording Constant scores.

Minimal-invasive treatment of distal femoral fractures with the LISS (Less Invasive Stabilization System): a prospective study of 30 fractures with a follow up of 20 months.

Background: There is no consensus on the best treatment of distal femoral fractures.

Patients And Methods: In a prospective study, we treated 29 patients with 30 distal femoral fractures with the Less Invasive Stabilization System (LISS) from 1997 to 2000. Almost 1/2 of them had open fractures, 1/3 extraarticular type A and 2/3 articular fractures type C (AO classification) and these had been caused by high-energy trauma with concomitant severe injuries or osteoporosis.

Cadaveric-biomechanical evaluation of bone-implant construct of proximal humerus fractures (Neer type 3).

Background: A biomechanical cadaver study was performed to test the stability and strength of screw osteosynthesis of surgical neck fractures of the humerus.

Methods: After bone density measurement, 64 cadaver proximal humerus bones were bent to create a subcapital fracture. The fracture was then stabilized by means of screw osteosynthesis randomly assigned to subgroups of screw positioning, size of screw, and stress test (torsion/bending).

The proximal femoral nail (PFN)--a minimal invasive treatment of unstable proximal femoral fractures: a prospective study of 55 patients with a follow-up of 15 months.

In 1996, the AO/ASIF developed the proximal femoral nail (PFN) as an intramedullary device for the treatment of unstable per-, intra- and subtrochanteric femoral fractures. In a prospective study, we treated 55 patients having proximal femoral fractures with the PFN from 1997 to 2000. In 34 patients, we achieved what was close to anatomic reduction of the main fracture fragments.
