INTRODUCTIONSkeletons are reliable age markers because teeth and bones develop at a predictable rate. Teeth are most accurate for ages up to 21, while the pelvis is a key indicator of adult age.OBJECTIVESTo analyze skull, pelvis, ribs and long bone changes in male and female subjects.To identify and document changes in skull, pelvis, ribs and long bones for agedetermination based on morphology.To determine the age of person by evaluate the morphology of the vertebral bone.MATERIALSOld vertebrate bonesYoung vertebrate bonesMETHODOLOGY1.Students were divided into 3 groups:Long bones (young and old ) – Alternative: Vertebral column2.Each part of the bone were examined for signs used in age determination,photograph and sketch.3.The bone specimens were switched with the other groups until each group has examined all available specimens after completing the examination.
RESULTSDifference Between Young and Old Vertebrate Bones:Young Vertebrate BonesOld Vertebrate BonesAge Estimation of Vertebral Bones:Young OldEpiphyseal ring seen and in the process of fusingEpiphyseal ring is obliteratedLine of fusion is clearOsteophyte growth is progressing on the edges of the vertebral bodiesStage 2 : Late Teenager ( 16 – 20)The bone is increasingly porous ( intervertebral surface)Stage 4 : Older adult ( 30 years and above)DISCUSSIONAdult bones are harder and prone to breaking, while child bones are more flexible due to different chemical composition. Children's bones may bend instead of breaking. Osteophytes usually do not cause issues and may only be discovered incidentally during an X-ray. However, they can cause problems if they rub against bone or muscles, impact movement, or put pressure on nerves, leading to pain and stiffness.
QUESTIONS1. Identify the suitable age range of each of the bone specimen with theappropriate justification.Suitable age for young bones is around teenagers age which is 13 – 30 while for older bones is around 60 years old and above.2. Provide an age range for the two individuals used during the practicalsession.Age range for the two individuals might be around 13 to 60 years old.CONCLUSIONFor summary, no standardized bone age assessment method currently exists.One hopes for improved age determination through advancements in bone assessment techniques.REFERENCES NHS.
