Abstract

INTRODUCTION: Particularly problematic in total hip revision arthroplasty is the cement removal out of the depth of the femoral canal; it is also costly in time and effort. The extracorporal shock wave lithotripsy proved to be an unsuitable method. With the present paper we proved experimentally a newly developed endoscopically controlled modified intracorporal lithotripter (Swiss Orthoclast) for the removal of bone cement. METHODS: We tested the efficiency on standardized cement specimens of different manufacturers in vitro. We compared both conventional removing techniques with mallet and chisel and a pneumatically powered chisel with formalin fixed human femora. During these experiments we measured the intrafemoral pressure distally to the cement layer. RESULTS: We achieved a high energy (max. 450 mJ) and a very effective fragmentation of the cement (40 mg fragments calculated on the single impulse of 350 mJ). The endoscopic control ensures a safe control of the cement removal even in the depth of the femoral canal. No bone damage occurred macroscopically and radiologically. No heat or toxic products developed. Using the Swiss Orthoclast the intrafemoral pressure was the lowest possible (7 mbar). Even with hammer and chisel or the pneumatically powered chisel the pressure was too low (max. 55 mbar with mallet and chisel) to cause a fat embolic syndrome. CONCLUSION: As a result of these experiments we started with clinical trials (with permission of the Ethic commission) to evaluate the practicability of the modified intracorporal lithotripter (Swiss Orthoclast) for cement removal.

96. Anatomical variations between the sciatic nerve and the piriformis muscle: A contribution to surgical anatomy in piriformis syndrome

Author

Natsis, K. Totlis, T. Konstantinidis, G.A. Paraskevas, G. Piagkou, M. Koebke, J.

Abstract

Purpose: To detect the variable relationship between sciatic nerve and piriformis muscle and make surgeons aware of certain anatomical features of each variation that may be useful for the surgical treatment of the piriformis syndrome. Methods: The gluteal region of 147 Caucasian cadavers (294 limbs) was dissected. The anatomical relationship between the sciatic nerve and the piriformis muscle was recorded and classified according to the Beaton and Anson classification. The literature was reviewed to summarize the incidence of each variation. Results: The sciatic nerve and piriformis muscle relationship followed the typical anatomical pattern in 275 limbs (93.6 %). In 12 limbs (4.1 %) the common peroneal nerve passed through and the tibial nerve below a double piriformis. In one limb (0.3 %) the common peroneal nerve coursed superior and the tibial nerve below the piriformis. In one limb (0.3 %) both nerves penetrated the piriformis. In one limb (0.3 %) both nerves passed above the piriformis. Four limbs (1.4 %) presented non-classified anatomical variations. When a double piriformis muscle was present, two different arrangements of the two heads were observed. Conclusions: Anatomical variations of the sciatic nerve around the piriformis muscle were present in 6.4 % of the limbs examined. When dissection of the entire piriformis is necessary for adequate sciatic nerve decompression, the surgeon should explore for the possible existence of a second tendon, which may be found either inferior or deep to the first one. Some rare, unclassified variations of the sciatic nerve should be expected during surgical intervention of the region. © 2013 Springer-Verlag.

Abstract

PURPOSE: To compare digital X-ray, CT, and MRI in the evaluation of ligamentous and osseous lesions in upper cervical spine specimens after artificial craniocervical injury with the findings of macroscopic preparation. MATERIALS AND METHODS: A rotation trauma of defined severity was applied to 19 human corpses. After dissection of the neck specimens, digital X-ray (DIMA Soft P41, Feinfocus), conventional and helical CT (CTi, High Speed, GE, collimation 1 mm; pitch 1.0), and MRI were performed from the skull base to C3. The findings were correlated with the macroscopic results of preparation. MR (Magnetom Vision, Siemens) imaging was obtained with a 1.5 T system using 2D- and 3D-sequences. RESULTS: Preparation revealed 6 fractures of the vertebral bodies, 5 fractures of the dens axis, 1 fracture of the arcus anterior of the atlas, 4 osseous flakes at the occipital condylus, and 6 lesions of the alar ligaments. Digital radiography showed all fractures and 4 osseous flakes at the occipital condylus. With conventional and helical CT, all fractures and all ruptured alar ligaments could be detected. 2D MRI depicted 9 of the fractures and 3D MRI showed fractures. With 2D MRI, 2 of the 4 osseous flakes at the condylus could be detected and with 3D MRI one occipital condylus fracture could be depicted. Ligamentous injuries were visualized by 2D MRI in 2 of 6 cases and by 3D MRI in one case. CONCLUSIONS: In post-mortem studies, CT was superior to MRI in the visualization of osseous and ligamentous injuries after trauma of the upper cervical spine. However, these results are not transferable to patients with rotation injury in general.

Abstract

Rotation of the radius about the fixed ulna is analysed radiographically in an anatomic specimen. While rotating the styloid process of the radius migrates in relation to the ulna. Compared to the prone position supination leads to a more distal position of the styloid process.
