The coexistence of temporomandibular disorders and styloid process fracture: A clinical report

WOS: 000238395200005PubMed: 16765153This clinical report describes the diagnosis and treatment of a patient with both temporomandibular disorders (TMD) and styloid process fracture. The presence of tender muscles of mastication, facial pain, especially upon awakening, frequent grinding sounds, and tooth attrition indicated a diagnosis of TMD with bruxism as a possible etiological factor. However, the preliminary diagnosis of styloid process fracture based on the patient's sensation of a foreign body in the throat and some discomfort when turning the head was confirmed using radiography. The styloid process fracture was treated using conservative nonsurgical therapy, and an occlusal splint was used to treat the TMD. The patient's symptoms were significantly reduced at the 12-month follow-up visit

An anatomical study of the meniscofibular ligament

We examined the anatomical structure of a ligament (ligamentum meniscofibulare) between apex fibulae and lateral meniscus by macroscopic and microscopic dissection and transillumination method in 50 knees of 25 cadavers (5 were fresh). We analyzed the function of this ligament, which runs between the head of the fibulae and lateral meniscus. The existence of a connection between knee joint and proximal tibiofibular joint was demonstrated by injecting colored liquid into the knee joint space and transillumination. The mensicofibular ligament is a capsular ligament originating from the lateral meniscus that is anterior to the popliteal muscle tendon. The meniscofibular ligament, which is attached to fibula with rotatory motion at one end and to the lateral meniscus at the other, is believed to position the lateral meniscus and therefore to play a key role in the knee joint

Axial rotation and mediolateral translation of the fibula during passive plantarflexion

Background: Since the fibula is linked to the ankle as well as the knee joint, its importance for knee and ankle disabilities should be investigated. This study evaluates its movement during range of motion of the ankle. Materials and Methods: An instrument, together with the experimental protocol, was devised to determine the relative motion of the fibula in reference to the tibia with motion of the ankle joint on 20 paired lower extremity cadaver specimens. Results: It was demonstrated in all specimens that the fibula had a relative rotation around its longitudinal axis and mediolateral translation with reference to the tibia with ankle motion. The distal end of the fibula rotates more compared to the proximal end. The mediolateral translation of the proximal end of the fibula is rather close to that of the distal end. Although there was no consistent pattern for rotation, dorsiflexion caused lateral translation and plantarflexion caused medial displacement for most of the specimens. Conclusion: A novel, invasive but relatively simple test setup was devised. Movement of the fibula which is important for the kinematics and kinetics of the knee and ankle joints was evaluated by this new device. Clinical Relevance: Evaluation of the fibula movement in normal lower extremities may lead to better understanding of its dynamic function which could have treatment implications for pathological conditions

Superficial palmar communications between the ulnar and median nerves in Turkish cadavers

WOS: 000250256800010PubMed: 17583587The superficial palmar communicating branch between the ulnar and median nerves, the ramus communicans (RC), has been investigated by anatomical dissections in 30 hands of 15 cadavers in the Turkish population. A communicating branch between the ulnar and median nerves was found in 18 hands (60%). It was classified into 4 types: Type 1-RC emerging from the ulnar 4th common digital nerve (CDN) and uniting with the median 3rd CDN, Type 2-RC emerging from the median 3rd CDN and uniting with the ulnar 4th CDN, Type 3-RC extending horizontally between the 3rd and 4th CDN, Type 4-a plexiform RC formed by multiple twigs. Twelve hands (40%) showed the Type 1 arrangement, one was Type 2 (3.3%), two were Type 3 (6.7%) and three (10%) were Type 4, based on the classification devised by Meals and Shaner ([1983] 3 Hand Surg Am 8:411-414) and modified by Bas and Kleinert ([1999] 3 Hand Surg Am 24:1171-1184). Knowledge of the anatomical characteristics of this branch is important for surgical interventions, especially in carpal tunnel release operations

The annular ligament - An anatomical study

Background: Despite documentations of ligamentous structures of the elbow, the anatomy and clinical and functional importance of the annular ligament has not been comprehensively defined in the orthopaedic literature

Numerical Study of the Aerodynamic Effects of Septoplasty and Partial Lateral Turbinectomy

Objectives: To investigate, first, the effects of septal deviation and concha bullosa on nasal airflow, and second, the aerodynamic changes induced by septoplasty and partial lateral turbinectomy, using computational fluid dynamics (CFD)

Surgical Anatomy and Bifurcation Patterns of the Popliteal Artery: An Anatomical Study

Comert, Ayhan/0000-0002-9309-838X; Esmer, Ali Firat/0000-0003-2511-9879WOS: 000266016400006Objective: To clarify the anatomy of the popliteal artery and to determine key variations in the bifurcation patterns of the popliteal artery. Material and Methods: The popliteal fossae of 28 (12 right and 16 left) fixed lower extremities were carefully dissected, and the arterial pattern from the distal edge of the adductor hiatus (AH) to the proximal portion of each leg was documented. A digital caliper was used to measure the arterial length. The transverse plane between the distal edges of the femoral condyles (FCs), which is easily located, was used as reference. Results: The mean length of the popliteal artery (PA) from the AH to the FCs was 9.26 +/- 1.63 cm on the right side and 10.08 +/- 2.12 cm on the left side, while the mean distance from the FCs to the site of bifurcation into the anterior and posterior tibial arteries was 7.20 +/- 1.98 cm on the right side and 6.69 +/- 1.15 cm on the left. The average arterial length from the level of the FCs to the site of origin of the peroneal artery was 10.01 +/- 1.78 cm on the right side and 9.18 +/- 1.07 cm on the left side, and the PA/extremity ratio was 0.21 +/- 0.04 on the right side and 0.22 +/- 0.04 on the left. Variable patterns of adult popliteal artery termination were observed. Conclusion: The data presented here can help reduce the complication rate and improve the success rate of both urgent and elective vascular procedures, which often require exposure of the popliteal artery
