Introduction: Adductor hiatus (AH), an osseo- muscular or osseo- fibrous space between adductor magnus muscle or aponeurosis and the shaft of femur has been classified into four different types. The interest in the hiatus is due to the large vascular structures that traverses the hiatus which is of concern to the surgeons. Materials and Methods: A total of 61 embalmed cadavers (102 limbs), 35 female lower limbs and 67 male lower limbs were dissected to show AH. Results: The bridging fibrous which shows the highest frequency was observed in 44 limbs. It exhibited incidence of 43.1% prevalence of AH shape on both sexes. The incidence in male was 27.5% while in female it was 15.7%. The bridging muscular type, the least occurrence shows incidence of 17.6% in both sexes; in males, 13.7% and in females, 3.9%. Oval fibrous type shows a prevalence of 20.5% in both sexes, 12.7% in males and 7.8% in females. Oval muscular type shows 18.6% incidence in both sexes. In males, 11.8% and in females, 6.9%. The distance from the apex of AH to the adductor tubercle was measured and shows a range of 5.0cm-17.0cm with a mean distance of 10.3cm. Conclusion: The result of this study showed that bridging fibrous AH type exhibited the highest prevalence depicting variation from another racial study. Therefore to adopt an appropriate surgical intervention in a situation of adductor canal outlet syndrome, the surgeon has to be aware of the population variations.
