Randomized Controlled Trial
Computer navigation in the reduction and fixation of femoral shaft fractures: a randomized control study.
We investigated the accuracy of reduction of intramedullary nailed femoral shaft fractures in human cadavers, comparing conventional and computer navigation techniques. ⋯ Computer navigation significantly improves the accuracy of femoral shaft fracture fixation with regard to leg length, but not rotational deformity.

Randomized Controlled Trial Comparative Study
[CT-guided marking of pulmonary nodules with a special lung marking wire before video-assisted thoracoscopic surgery - review of 184 cases].
Minimally invasive techniques like video-assisted thoracoscopic surgery (VATS) are currently the method of choice for the resection of small pulmonary nodules, when they are located in the periphery of the lungs. To guarantee quick and safe intraoperative identification of the nodule, preoperative marking is necessary and sensible. We report about our experiences in 184 markings with a special lung marking wire, which is placed in or around the pulmonary nodule using CT guidance. ⋯ CT-guided marking of pulmonary nodules using a special marking wire followed by thoracoscopic resection is an efficient and safe method for diagnosing suspicious nodules in the periphery of the lung.

Case Reports
Percutaneous cement augmentation of a lytic lesion of C1 via posterolateral approach under CT guidance.
Percutaneous vertebroplasty (PV) can provide pain relief and biomechanical stabilization of lytic metastasis of the spine in selected patients. Percutaneous vertebroplasty of the atlas has been reported in only five cases and has been performed with different techniques and approaches. ⋯ Computed tomography-guided PV of C1 lytic lesion with posterolateral approach was effective in the described case for pain control and stabilization, and it may be a therapeutic option in selected patients to avoid occipitocervical fusion. This procedure requires good understanding of the anatomy and rigorous technique to avoid potential complications.

Review Case ReportsA novel method of image-based navigation in fracture surgery.
The treatment of three- and four-part fractures of the humeral head is still controversially discussed. Some advocate primary arthroplasty while the results of primary fixation seem to be superior if no necrosis of the humeral head develops. Today navigation is used in orthopaedic surgery mainly for interventions on the spine, the pelvis and arthroplasty. ⋯ In conclusion, the described technique allows an accurate fixation of the humeral head fracture as the guidance system (Surgix) ensures the "first try first hit" screw positioning. The new system was integrated in the workflow and supports the surgeon as an aiming device. The role of navigation system in enhancing minimally invasive surgery of the shoulder should be further explored.
