BACKGROUND/AIM To assess the possibility of the eruption of the lower third molar on the basis of the measured parameters: retromolar space, mesiodistal crown width of a molar and the third molar angulation. METHODS The investigation included 104 patients both sexes (43 boys, and 61 girls), 16 to 25 years old (mean age, 18 years). It was performed using the orthopanthomographic radiographs an...

Femoral and tibial shaft fractures are common injuries in the United States. Since their introduction, reamed intramedullary nails have become the treatment of choice for most of these fractures. However, delayed union and nonunion can complicate treatment in up to 10% of patients. Removal of interlocking screws, or dynamization, can promote fracture healing in cases of delayed union or nonunio...

In this paper, the e ect of shaft rotation on its natural frequency is investigated. Considering rotary inertia and gyroscopic momentum, the fourth order di erential equation representing the exural vibration of the shaft is solved by the new analytical method. The Distributed Lumped Modeling Technique (DLMT) is applied to obtain the transfer matrix for the distributed elements using the propos...

The feeding apparatus of Pratylenchus penetrans (Cobb) Chitwood and Oteifa was studied by means of the electron microscope. The stomatostylet is composed of tooth, shaft, and basal knobs. The tooth and shaft are closely interlocked. The tooth forms the outer covering and the inner lining of the anterior half of the stylet, whereas the shaft extends from the basal knobs to the level of the style...

Femur fractures are common in paediatric population and femoral shaft fractures have an incidense of 1.4-1.7% of all paediatric fractures. These are often seen in boys rather than girls. Most of the fractures are transverse, non-comminuted and closed [1]. The mechanism of the femoral shaft fracture for older children is associated with high-energy transmission such as traffic accidents. Combine...

INTRODUCTION Anterior dislocation of the shoulder joint with an ipsilateral fracture of the humeral shaft is a rare injury which may require demanding technical skills. CASE PRESENTATION A 33 years old male sustained a work accident. Radiographs showed an anterior dislocation of the shoulder with a transverse fracture of the middle third of the humeral shaft on the same side. The dislocation ...

Shaft sinking is one of the main parts in underground mine planning. Shaft has various applications in underground mines e.g. minerals exiting flow, gases entrance or exit way, stope developments for exploitation etc. Considering that this section requires an abundance of expenses, management always following the election is the way that both terms have the technical considerations, economic co...

Radial nerve palsy, either axonotmesis or neurapraxia, associated with fractures of the shaft humerus occurred in about 10 percent of the patients with humeral shaft fractures [1,2,3]. Its close relation to the humerus, especially fractures of the middle and the distal thirds of the humerus makes the radial nerve vulnerable to such injuries [4,5,6]. There are many debate about the management of...

BACKGROUND Long-stem tibial components are available for complex primary and revision total knee arthroplasties. Most of the stems' designs are based on anatomic data from Western populations. We conducted a morphologic study to determine the relationship of the tibial shaft to the tibial plateau in Chinese people. METHODS We included knees from fifty Chinese individuals (twenty-five females ...

BACKGROUND Humeral shaft fractures account for 1 to 3% of all fractures in adults and for 20% of all humeral fractures. Non-operative treatment is still the standard treatment of isolated humeral shaft fractures, although this method can present unsatisfactory results. Surgical treatment is reserved for specific conditions. Modern concepts of internal fixation of long bone shaft fractures advoc...
