Objective: The most common site of ulnar nerve (UN)
entrapment neuropathy is the cubital tunnel (CT). Although
the floor of the CT is carved out by the capsule of the elbow
and the ulnar collateral ligament, the cubital tunnel retinaculum
(CTR) and flexor carpi ulnaris aponeurosis carve out the
roof of it. Having knowledge these morphological structures
will contribute to the determination of the treatment methods.
Methods: The healthy and sick elbow’s MRI of 31 patients,
who consulted The Hospital of Necmettin Erbakan University
Meram School of Medicine with pain at medial of the elbow
and early diagnosis of cubital tunnel syndrome were viewed,
prospectively. Anteroposterior and mediolateral diameter of
the CT and UN were measured. Width, thickness and length
of CTR and the UN length in the CT were measured and the
UN’s position was determined under CTR. The cubital angle
and at 3 level the UN groove’s base angle were measured.
Results: At healthy elbow; the maximum width of CTR was
determined 1.31 mm and 1.03 mm in extantion and 90° flexion
position, respectively. These values were measured as 1.2 mm
and 1.03 mm at sick elbow, respectively. In the healthy and sick
elbow, there is a significant difference with both thickness and
length of CTR between positions. Diameter values of all
parameters with elbow position were seen to be changed. It was
observed that the UN groove’s base angle was widened distally.
