Introduction:Skeleton plays a significant role in various sciences like medicine, forensic sciences, anthropology etc. and also in estimation of sex, age, race and stature of an individual.The knowledge about different diameters of head and neck of femur is essential in orthopaedic surgery in prosthesis and nail application, for radiological practice in identifying pathology of bone and also for determining age. Method:The present study was conducted on 80 dry femur bones of unknown age and sex, which were obtained from Department of Anatomy, GMC Jammu. Circumference of femoral neck,length of femoral neck,vertical diameter of femoral neck, andtransverse diameter of femoral neck were measured.Result:Mean circumference of neck of right and left femur bones is 10.29 (SD 0.81) cms with a range of 8–12 cms and 10.17(SD 0.69) cms with a range of 8.5–12 cms respectively.Mean femoral neck length of right and left sided bones is 3.19 (SD 0.32) cms with a range of 2.5–4.5 cms and 3.24 (SD 0.28) cms with a range of 3–4 cms respectively. Mean neck vertical diameter of right and left femur bones is 30.76 (SD 2.75) mm with a range of 24.2–35.9 mm and 30.57(SD 3.26) mm with a range of 22.3–36.8 mm respectively. Mean neck transverse diameter of right and left femur bones is 24.62 (SD 2.41) mm with a range of 17.6–29 mm and 24.60 (SD 2.54) mm with a range of 19.3–29 mm respectively   Conclusion:the knowledge of the present study will be veryuseful for designing implants used for surgicalcorrection of femoral neck fracture; for radiological practicein identifying pathology of bone, determiningage and in reconstruction surgeries. It couldhence be stated that this study will prove to beuseful along the broad spectrum of medicalscience such as anatomy, radiology, orthopedics and forensic medicine.
