Evaluation of the fibular incisura of the tibia with magnetic resonance imaging.

Knowledge of the distal tibiofibular syndesmosis should be helpful in determining the normal position of the fibula in the incisural notch. The purpose of this study was to determine the anatomic characteristics of the fibular incisura of the tibia on MR imaging. One hundred fifty lower limbs (43 male, 32 female volunteers) were examined with MRI. The length of the anterior facet was 10.4 mm in males and 8.9 mm in females, and the length of the posterior facet was 10.4 mm in males and 8.9 mm in females. The angle between anterior and posterior facets was 138.6 degrees in males and 139.9 degrees in females. The depth of the fibular incisura of the tibia was 3.6 mm in males and 2.9 mm in females. The vertical distance of tibiofibular overlapping was 7.9 mm in males and 7.0 mm in females. The distance between anterior margin of the tibia and anterior margin of the fibula was 14.3 mm in males and 12.5 mm in females. All of these parameters of men (except the angle between anterior and posterior facets) were significantly higher than the parameters of women (p<.001, p<.001, p<.05, p<.05, p<.01, respectively).

Urethral duplication.

Urethral duplication is a rare congenital anomaly. Although a number of theories have been proposed to describe the embryology of the condition, the actual mechanism of the disorder is still unclear. We report here a case of urethral duplication in a 11-year-old boy complaining of a double stream, and review the current literature on this rare entity.

Frequency in the anomalous origin of the right coronary artery with angiography in a Turkish population.

OBJECTIVE: The estimate frequency of anatomic variations in origin of the right coronary artery in a Turkish population. MATERIAL AND METHOD: The angiographic data of 5253 consecutive adults patients undergoing coronary angiography were analysed retrospectively for the diagnosis of anomalous origin of the right coronary artery. RESULTS: Among 5253 adults patients, five (0.09%) patients had anomalous origin of the right coronary. They had an isolated anomalous origin of the right coronary artery. The right coronary arose from the left coronary sinus of Valsalva (there was separate orificium for the right coronary artery and the left coronary artery) in two (0.03%) patients, from above the left coronary sinus of Valsalva in three (0.05%) patients. In all patients, the anomalous origin of right coronary artery from the left sinus of Valsalva and from above the left coronary sinus of Valsalva coursed between the aorta and the pulmonary artery. CONCLUSION: The anomalous origin of the right coronary artery is a rare congenital cardiac malformation. Most patients remain asymptomatic. However, there are cases of sudden cardiac death described in the literature, indicating a potentially malign course of the disease. The angiographic recognition of this vessel may be useful for physicians dealing with diagnosis and treatment of the anomaly of the right coronary artery.

Single coronary artery arising from the right sinus of Valsalva (case report).

A single coronary artery is a rare congenital anomaly of the coronary arteries where only one coronary artery arises from the aortic trunk by a single coronary ostium, supplying the entire heart. We report a case of a 70 years-old man with mitral valvular insufficiency and atherosclerotic right and left circumflex coronary arteries, in whom coronary angiography showed a single coronary artery arising from a single ostium in the right sinus of Valsalva (R-II-B subtype) and transverse trunk coursed between aorta and pulmonary artery. The clinical significance and subtype of the single coronary artery are discussed.

The fibular incisura of the tibia with recurrent sprained ankle on magnetic resonance imaging.

OBJECTIVE: The aim of this study was to investigate the fibular incisura of the tibia in type I and II recurrent sprained ankle. METHODS: A total of 18 limbs (9 right, 9 left) were examined for the fibular incisura of the tibia by magnetic resonance imaging at Gunmar Magnetic Resonance Imaging Center between September 2000 to May 2001. This group consisted of 10 males and 8 females and their age ranged between 18-61 years. The control group was made up of 75 participating volunteers without previous history of trauma in the ankle. RESULTS: The measurements of the length of the anterior and posterior facets, depth of the fibular incisura of the tibia and the distance between anterior margin of the tibia and anterior margin of the fibula in the patient group were visibly different from the measurements of the control group. In recurrent sprained ankle, the anterior and posterior tubercles were lengthier, the depth of the fibular incisura of the tibia was deeper and the fibula was more anterior than the control group. The measurements of the angle between anterior and posterior facets and the vertical distance of tibiofibular overlapping in the patient group were slight different from the measurements of the control groups. CONCLUSION: These characteristics, which were observed in the recurrent sprained ankles, may be anatomically predisposed to recurrent ankle sprains.

The congenital absence of the radius, scaphoid, trapezium, thumb and hypoplasia of the lunate.

The congenital absence of the right radius, scaphoid, trapezium, thumb and hypoplasia of the lunate are described in a 9-year-old boy. He had full extension of his elbow, while flexion motion was limited to 90 degrees. His hand was radially deviated. The thumb was absent. The index and middle fingers were united and immobile. The ring finger had movement only at the metacarpophalangeal joint, while the little finger had full motion. Complete blood count fell within normal ranges. He had no other malformations or mental retardation. No hereditary family history was found and there was no consanguineous marriage. This case is different from cases mentioned in the literature due to lunate hypoplasia and the anomalies of the index, middle and ring fingers.

Variants in origin of the left circumflex coronary artery with angiography.

OBJECTIVE: The objective of this study was to assess the anatomic variations in the origin of the left circumflex coronary artery in a Turkish population. METHOD: This study was carried out at the Sani Konukoklu Medical Center, Gaziantep, Turkey, during the period January 1999 through to May 2001. The angiographic data of 10,042 consecutive adult patients who underwent coronary angiography was analyzed for anomalous origin of the left circumflex coronary artery. RESULTS: Among 10,042 adults patients, 27 (0.3%) had anomalous origin of the left circumflex coronary artery. The left circumflex coronary artery arose from the left coronary sinus of valsalva in 15 (55.5%) patients, from the right coronary sinus of valsalva in 7 (25.9%) patients, and from the proximal part of the right coronary artery in 8 (29.6%) patients. CONCLUSION: The anomalous origin of the left circumflex coronary artery may not always be benign. Therefore, recognition of this anomaly is mandatory to prevent the risk of infarction or sudden death. Special surgical considerations must be made when performing valvular replacement in patients with anomalous left circumflex coronary artery.

Single coronary artery arising from the left sinus of valsalva.

A single coronary artery is a rare congenital anomaly of the coronary arteries where only one coronary artery arises from the aortic trunk by a single coronary ostium, supplying the entire heart. We report a case of a 57-year-old woman with atypical chest pain, in whom coronary angiography showed a L-I subtype single coronary artery (arising from a single ostium in the left sinus of valsalva) without associated cardiovascular disease. The clinical significance and subtype of the single coronary artery are discussed.
