Restoration of axis, length, and rotation of the lower leg. Sufficient primary stability of the osteosynthesis for early functional aftercare. Maintaining mobility of knee joint. Bone healing in closed and open fractures. ⋯ In a prospective multicenter study on the stabilization of tibia fractures with the Expert Tibial Nail, 22 patients with proximal third tibia fractures were documented. Seventeen patients could be reviewed clinically and radiologically after 1 year. A non-union was registered in 1 patient (5.9%), a malalignment in any plane above 5° in 3 fractures (17.6%).

Clinical Trial[Angle-stable fixation of intramedullary nails using the Angular Stable Locking System® (ASLS)].
Greater stability in intramedullary osteosynthesis using angle-stable fixation with intramedullary nails and proximal locking screws. A novel screw-and-sleeve system (ASLS®, Synthes GmbH, Oberdorf, Switzerland) is applied using normal cannulated nails. Decisions can be made intraoperatively. ⋯ A multi-center pilot study has shown the technique to be reproducible and simple. There have been no complications using this technique to date. Biomechanical laboratory studies have demonstrated that stability with respect to axial and torsional loading is statically and dynamically higher than with conventional nailing. Device failure occurs later. Further applications as well as results of a prospective randomised study currently under way will show how great the clinical advantages ultimately prove to be.

Anatomical glenoid reconstruction via a J-bone graft for recurrent posttraumatic anterior shoulder dislocation.
To reconstruct the anatomical glenoid shape in cases of osseous glenoid rim defects after recurrent posttraumatic anterior shoulder dislocation to restore stability without severely compromising the range of motion. ⋯ A total of 47 shoulders were followed-up after an average of 90 months (range 25-152 months). The mean Rowe scores were 94.3 for the affected shoulder and 96.8 for the uninjured shoulder. The Constant scores reached 93.5 and 95 points, respectively. Loss of external rotation was 4.4°. In addition, 24 shoulders were followed-up by computed tomography (CT). There were no recurrences, with the exception of one traumatic graft fracture. Of 19 patients with arthropathy at follow-up, 11 already had arthropathy prior to the procedure.
