identification of the lateral femoral safe zone for Drilling during liss plate fixation of distal femur fractures
Injury-international Journal of The Care of The Injured, 2020Co-Authors: Saeed Asadollahi, David Holcdorf, Damien L Stella, Andrew BucknillAbstract:Abstract Background The incidence of arterial injury associated with femoral fractures is approximately 1%. Lateral sub-muscular plate fixation is gaining popularity for the management of distal femoral fractures. The objective of this study was to assess the iatrogenic risk to the superficial femoral artery (SFA) during Less Invasive Stabilisation System (LISS) plate fixation of distal femoral fractures by analysing the range of distances and angles between LISS plate screws and the Drilling Line to the SFA. Materials and methods We identified all patients who underwent LISS plate fixation of distal femoral fractures between 2008 and 2018 in our level-1 trauma centre. Patients who underwent postoperative computed tomography for any reason were eligible for inclusion in the study. Twenty-five patients met the inclusion criteria. The sample comprised 10 male and 15 female patients with a mean age of 55 years. The most common fracture type was a supracondylar femur fracture (56%), followed by an intercondylar fracture (36%). A 13-hole LISS plate was the most common plate length used (44%). A consultant radiologist reviewed all scans to verify the visibility and marking of the SFA. Results The median distance between the screw tip and the SFA was 21 mm (range, 8–65 mm). There was a negative correlation between the LISS plate hole number and the trajectory of Drilling (Pearson coefficient: −0.87, p Conclusion Extra care is needed when Drilling into the LISS plate holes from the lateral to the medial direction in order to reduce the risk of iatrogenic injury to the SFA, especially in the high-risk plate zone where the artery can be close to the Drilling Line.

topographic changes in petrous bone anatomy in the presence of a vestibular schwannoma and implications for the retrosigmoid transmeatal approach
Operative Neurosurgery, 2014Co-Authors: Florian H Ebner, Maximilian Kleiter, Soren Danz, Ulrike Ernemann, Bernhard Hirt, Hubert Lowenheim, Florian Roser, Marcos TatagibaAbstract:BACKGROUND The maneuver of transmeatal Drilling carries the risk of injuring inner ear structures, which may cause immediate or delayed hearing loss. OBJECTIVE To describe the changes in petrous bone anatomy caused by the tumor and to analyze both the incidence and the risk pattern for violation of the endolymphatic system in a surgical series. METHODS One hundred patients operated on for vestibular schwannoma were included in this prospective study. Thin-slice computed tomography was performed before and after surgery. We assessed topographic measurements on both the pathological and healthy sides. Postoperatively, we evaluated anatomic and functional values. RESULTS The diameter of the internal auditory canal was significantly larger (P < .001) in the petrous bones of the affected sides than in the contralateral healthy sides. An average of 5.6 ± 1.8 mm of the internal auditory canal was drilled, and the distance from the medial border of the sigmoid sinus to the Drilling Line (tangential to the drilled surface of the posterior lip of the internal auditory canal) was 9.8 ± 2.9 mm. A postoperative violation of the vestibular aqueduct (VA) was detected in 41 cases; the VA was intact in 55 cases; and the VA could not be clearly defined in 4 cases. The incidence of VA injury increased with increasing tumor size. In the patient group with good preoperative and postoperative hearing function, a VA injury occurred in 26% of cases, whereas the incidence increased to 67% in preoperatively deaf patients. CONCLUSION Vestibular schwannomas cause significant distortion of the petrous bone anatomy. Detailed preoperative knowledge of the topography is necessary for the preservation of function.
