BACKGROUND The anatomy of sternum is very important in case of sternal injuries and various surgeries. Our study is focussed on CT based morphometry of sternum. METHODS The study was carried on 52 chest CT films between age group of 10 to 60 yrs. CT scans were randomly collected from Department of Radiology, GMC, Srinagar and from some private radiological centres of Srinagar. Through these chest CT films, the parameters measured were manubrium length, sternal body length, xiphoid length and total length of sternum. These parameters were measured in cms. Presence of sternal foramina was noted. RESULTS Mean manubrium length was measured as 3.42±0.34 cms. Mean body length was measured as 7.81±0.51 cms and mean xiphoid length was measured as2.52±0.17 cms. All the parameters were increased for elderly age group. Mean total length of sternum was noted as 13.75±1.19 cms. Sternal foramen was noticed in 2 cases only CONCLUSION The knowledge of the morphometry of sternum is very important tool in the forensic medicine and in various medicolegal investigations. Sternal foramen in the sternum also holds medicolegal importance.
