ABSTRACT
Introduction: The Study of dimensions of head and neck of femur is important for making of appropriate prosthesis in hip replacement surgery. Different size of dimensions of head and neck of femur can affect the hip joint movement. The dimensions of head and neck of femur is varies according to age, race, heredity, ethnicity and geographical factor. Length of femur and stature of an individual can be determined even if only a fragment of proximal end of femur is available. Objective: To determine the functional implication of variation in dimension of head and neck of femur, which may be helpful for orthopaedic surgeons and forensic experts. Materials and Methods: Fifty human femur bones (25 of each side) were used for the study. Measurement of dimensions of head and neck of femur was done to know the average length of femur, vertical and transverse diameter of head, head circumference, anterior and posterior neck length and neck shaft angle of femur. All the measurement were taken with the help of Osteometric board, Circumference measuring tape, Digital vernier calliper and Goniometer. Results: The following mean values of dimensions of total 50 bones: Length of femur were 435.1±26.0 mm.Vertical and Transverse diameter of head of femur were 40.97±3.46 mm and 41.74 ± 2.76 mm respectively. Head circumference were 133.25±11.57 mm. Anterior and Posterior Neck length were 29.75±5.30 mm and 35.03±4.87 mm respectively. Neck shaft angle were 125.96±6.10 degree . Conclusion: Appropriate prosthesis for orthopaedic surgeries can be designed from the result of this study.
ABSTRACT
Background: Clavicle is a curved modified long bone placed horizontally at the root of neck. It transmits theweight of upper limb to the axial skeleton. The aim of this study is to determine position, number, and directionof nutrient foramen.Material method: The present study was conducted on 50 (25 right and 25 left) dried clavicles, in the departmentof Anatomy, Forensic medicine, Narayan Medical College, Jamuhar, Sasaram, Bihar.Result: The nutrient foramen was present in all the clavicles. One nutrient foramen was present in 70%, two in24% and three in 6% of clavicles. Predominant position of nutrient foramen was on the posterior surface(55.88%) and predominant location was in the middle one third (70.58%) of clavicles. Direction of all the nutrientforamina were towards the acromial end.Conclusion: The study of number, position, location and direction of nutrient foramina of clavicles are useful topreserve the arterial supply during surgical procedure like internal fixation and vascularised bone graft.KEY WORDS: Clavicle, nutrient foramen, foramen index, acromial end, sternal end, vascularised bone graft
