Abstract
Osteometry is the branch of anthropometry concerned with the measurement of bones. Osteometric parameters of the proximal tibia is important in forensics (sex and racial identification), prosthesic (precision in implant sizing) and in clinical practice (diagnosis and treatment). It is therefore important to have reference data for the Nigerian population. The study sought to determine morphometric parameters of the proximal tibia in Nigerians. The study involved a total of 100 dried tibia bones consisting of 60males and 40 females obtained from cadavers in anatomy departments of various Universities in Nigeria. The bones were macerated and measurements taken directly using a verner caliper. Data were expressed as mean ± standard deviation. Z-test was used to compare mean values and a probability level of p<0.05 was considered significant. Measurements were taken in centimeters. Identification and demarking point analysis was used for sexing of proximal tibia parameters. The index of sexual dimorphism was also applied to ascertain level of sexual difference. There was statistically significant difference between males and females (p<0.05) in all the parameters. No significant bilateral difference was seen in any parameter. Identification and demarking point analysis showed a higher degree of sexual difference between male and female and more bones were identified with identification point. The index of sexual dimorphism also indicated a higher level of sexual difference in all parameters with values greater than 100. This study provides reference data of the proximal tibia morphology in Nigerian population. The differences recorded in the proximal tibia morphology between genders might be useful in sexual and racial identification and in the design of knee prosthesis for the Nigerian population. Since no significant bilateral differences were observed, the contralateral healthy side can be safely used for preoperative templating.
