This study compared two Computer Assisted Surgery (CAS) methods in 212 total knee arthroplasties to evaluate the differences between anatomic landmark axes in determining rotational position of the femoral component. Overall, there were large variations between CAS defined component orientation using an optimized gap-balancing technique and component orientation using anatomic reference axes (r...
Statement of Problem:The determination of the dental midline is necessary in most dental procedures.One of the methods to fulfill this goal is to determine the facial midline based on the midpoints of the forehead, nose, upper lip and chin. However, for various reasons, this method has not always been proved successful. In such cases, different techniques, based on the investigations in the ede...
the purpose of this study was to identify the anatomic structures of the abdominal region of cat throughcomputed tomography (ct) to be used by veterinary radiologists, clinicians and surgeons. the abdominalregion of four cats were scanned twice, with and without using contrast medium in a same position, usinghigh-resolution imaging protocol. slice intervals were 11 mm and were adjusted so that ...
BACKGROUND The posterior interosseous nerve (PIN) can be difficult to locate within the radial tunnel. The deep branch of the radial nerve (DBRN) enters the supinator muscle after passing under the arcade of Fröhse. It courses through the superficial portion of the supinator muscle to exit distally as the PIN. Anatomic landmarks could facilitate diagnosis and treatment of radial tunnel syndrome...
OBJECTIVE Knowledge of anatomic landmarks for the first dorsal compartment can assist clinicians with management of de Quervain's disease. The radial styloid, the scaphoid tubercle, and Lister's tubercle can be used as superficial landmarks for the first dorsal compartment. METHODS Thirty-two cadaveric wrists were dissected, and measurements were taken from the predetermined landmarks to the ...
OBJECTIVE Basal joint arthritis is a common cause of pain and disability, particularly in elderly women. Corticosteroid injection with splinting provides a reliable long-term relief for patients with mild arthritis. Proper location of the basal joint with anatomic landmarks can facilitate diagnosis and treatment of basal joint arthritis while avoiding inadvertent injury to local structures. The...
This article presents the endoscopic anatomy of the retrotympanum and its relationship to other important anatomic landmarks in the middle ear to provide understanding of its importance and relevance during surgeries. A well-detailed tour of the retrotympanum, its associated structures, variability of anatomic structures, and surgical relevance is presented.
HYPOTHESIS Using Lister's tubercle and the ulnar styloid as landmarks, accurate localization of the distal radioulnar joint can be achieved without the need for an image-guided approach. METHODS Cadaveric dissection of 16 upper extremities was performed to measure the relationships between the ulnar styloid, Lister's tubercle, and the distal radioulnar joint. In each specimen, the location of...
BACKGROUND AND OBJECTIVES The vertical sleeve gastrectomy is a common bariatric procedure. The operation is relatively standard, but there are still variations among surgeons. The two main variations are bougie size and extent of distal resection. Some surgeons will start the gastric resection at 2 cm proximal to the pylorus, whereas others start at 6 cm. Our hypothesis is that there are anatom...
Central venous catheterization is a typical technique performed in the emergency department and intensive care unit. Most subclavian vein access may be inserted without help, using anatomic landmarks alone. This study aimed to present precise procedure of central via endovascular techniques simulation video clip.
