PATTERNS OF ADDUCTOR HIATUS IN NIGERIANS: A CADAVERIC STUDY

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.

Primary hydatid cyst in the adductor magnus muscle

Human hydatid cyst is a zoonotic disease caused by the larvae of the Echinococcus species, most commonly the Echinococcus granulosus. Although hydatid cyst can cause disease almost anywhere in the human body, it most commonly affects the liver and lungs. Primary musculoskeletal hydatid involvement is a very rare occurrence even in endemic regions. Musculoskeletal hydatid disease shows no pathognomonic clinical signs and symptoms. And the contribution of serology to the diagnosis is negligible due to the high rate of false-negative results. Therefore, radiological imaging studies have a critical role in the diagnosis of the disease. To the best of our knowledge, there are only a few case reports of primary hydatid involvement of the adductor magnus muscle in the current literature. Here we present a 55-year-old female patient with primary hydatid cyst in the adductor magnus muscle and discuss the case in terms of imaging.

Medial circumflex femoral artery flap for ischial pressure sore

ABSTRACTA new axial pattern flap based on the terminal branches of the medial circumflex femoral artery is described for coverage of ischial pressure sore. Based on the terminal branches of the transverse branch of medial circumflex femoral artery, which exit through the gap between the quadratus femoris muscle above and the upper border of adductor magnus muscle below, this fascio cutaneous flap is much smaller than the posterior thigh flap but extremely useful to cover ischeal pressure sores. The skin redundancy below the gluteal fold allows a primary closure of the donor defect. It can also be used in combination with biceps femoris muscle flap.
