Introduction: The aims of this study are to define the
coracoid process anatomy in a Malaysian population, carried
out on patients in Hospital Serdang with specific emphasis
on the dimension of the base of coracoid process which is
important in coraco-acromial (CC) ligament reconstruction,
to define the average amount of bone available for use in
coracoid transfer, and to compare the size of coracoid
process based on gender and race, and with findings in
previous studies.
Materials and Methods: Fifteen pairs of computed
tomography (CT) based 3-dimensional models of shoulders
of patients aged between 20 to 60 years old were examined.
The mean dimensions of coracoid were measured and
compared with regards to gender and race. The data were
also compared to previously published studies.
Results: The mean length of the coracoid process was 37.94
± 4.30 mm. Male subjects were found to have larger-sized
coracoids in all dimensions as compared to female subjects.
The mean tip of coracoid dimension overall was 19.99 +
1.93mm length x 10.03 + 1.48mm height x 11.63 + 2.12mm
width. The mean base of coracoid dimension was 18.96 +
3.71mm length x 13.84 + 1.76mm width. No significant
differences were observed with regards to racial
denomination. The overall coracoid size measurements were
found to be smaller compared to previous studies done on the
Western population.
Conclusion: This study may suggest that Malaysians have
smaller coracoid dimension compared to Caucasians. The
findings further suggest that the incidence of coracoid
fracture and implants pull out in Malaysian subjects may be
higher.

Introduction: Corona Mortis (CMOR) is a term used to
describe an anatomical vascular variant of retropubic
anastomosis located posterior to superior pubic ramus. We
aim to provide sufficient data on the incidence, morphology
and mean location of ‘crown of death’ in Asian population.
Other objectives include to assess the relationship between
CMOR incidence with gender, race and age.
Materials and methods: This is a cross-sectional cadaveric
study involving 164 randomly selected fresh multiracial
Asian hemipelves (82 cadavers). Hemipelves were dissected
to expose and evaluate the vascular elements posterior to
superior pubic rami. Data were analysed using Chi-Square, ttest and with the help of IBM SPSS Statistics v26 software.
Results: CMOR was found in 117 hemipelves (71.3%). No
new morphological subtype was found. The mean distance of
CMOR to symphysis pubis was 54.72mm (SD 9.35). Based
on the results, it is evident that precaution needed to be taken
at least within 55mm from symphysis pubis during any
surgical intervention. The lack of statistically significant
correlation between CMOR occurrence and gender, race and
age suggest that the incidence of CMOR could be sporadic in
manner.
Conclusion: We conclude that CMOR is not just aberrant
vessel as the incidence is high and this finding is comparable
to other studies. The mean location of CMOR obtained in
this study will guide surgeons from various disciplines in
Asia to manage traumatic vascular injury and to perform a
safe surgical procedure involving the pelvis area.
