The condition shown in the picture above represents Extravaginal torsion.
Extravaginal torsion occurs in the fetus or neonate, because the testes may freely rotate prior to the development of testicular fixation via the tunica vaginalis within the scrotum.
Normal testicular suspension ensures firm fixation of the epididymal-testicular complex posteriorly and effectively prevents twisting of the spermatic cord. In males with the bell-clapper deformity, torsion can occur because of a lack of fixation, resulting in the testis being freely suspended within the tunica vaginalis.
An abnormal mesentery between the testis and its blood supply can predispose it to torsion if the testicle is broader than the mesentery. Contraction of the spermatic muscles shortens the spermatic cord and may initiate testicular torsion.
