Usefulness of slice encoding for metal artifact correction (SEMAC) technique for reducing metal artifacts after total knee arthroplasty
European Journal of Orthopaedic Surgery & Traumatology, 2019Co-Authors: Ahmed Jawhar, Miriam Reichert, Michael Kostrzewa, Mathias Nittka, Ulrike Attenberger, Henning Roehl, Frederic BludauAbstract:Purpose To evaluate the usefulness of a novel MRI sequence strategy in the assessment of the periprosthetic anatomical structures after primary total knee arthroplasty. Methods Two MR sequences were retrospectively compared for the imaging of 15 patients with implanted cruciate-retaining/fixed-bearing TKAs (DePuy, PFC Sigma): a slice encoding sequence for metal artifact correction (SEMAC) and a standard sequence. Images were acquired on a 1.5-T system. The degree of artifact reduction was assessed using several qualitative (Likert-type scale) (artifact size, distorsion, blur, image quality, periprosthetic bone, posterior cruciate ligament, lateral collateral ligament, medial collateral ligament, patella Tendon, popliteal vessels) and quantitative (artifact volume, Insall–Salvati index, length of patella/Tendon, Prosthesis dimensions) parameters by blinded reads performed by four investigators. The SEMAC sequences were statistically compared with the standard sequence using Wilcoxon test. Additionally, the intraclass correlation coefficient (ICC) for interobserver agreement was calculated. Results Higher levels of blurring were found with SEMAC compared to standard sequences ( p

Removal of a silicone Tendon Prosthesis six years after insertion for flexor Tendon reconstruction: a case report -
Hand and Microsurgery, 2012Co-Authors: Tolga Eryılmaz, Ali Çağrı Tekin, Şafak UygurAbstract:Two-staged flexor Tendon repair rely on the effect of the pseudo-Tendon sheath that developed by the effect of the silicone Tendon Prosthesis. The second stage of the reconstruction is performed 1 to 6 months after the first operation by removal of the silicone Tendon Prosthesis and Tendon grafting. In this study, we are presenting a removal of silicone Prosthesis 6 years after insertion for flexor Tendon reconstruction.

Secondary repair of flexor Tendon injuries.
Injury, 2013Co-Authors: Bruno Battiston, P.f. Triolo, A. Bernardi, Stefano Artiaco, Pierluigi TosAbstract:Tendon adhesions or even secondary ruptures causing severe hand functional impairment still represent a frequent complication after repair of flexor Tendon injuries. Secondary treatment of these problems includes tenolysis, one or two stages flexor Tendons reconstruction by grafts or even the use of Tendon Prosthesis. The mechanism and severity of injury, the status of the surrounding tissues and injured finger, the presence of associated lesions, the age of the patient, post-operative management, patient motivation and the surgeon's skill, may all have implications in the final outcome of the Tendon reconstruction. A correct evaluation of the problem by means of classifications such as the one described by Boyes, may help the surgeon in choosing the appropriate technique.
