Three-dimensional alignment of the upper extremity in the standing neutral position in healthy subjects.

Background: Though alignment of the spine and lower extremities in the standing neutral position has been evaluated, a few studies evaluating the alignment of the upper extremities have also been made. This study assessed the normal alignment of the upper extremities in the standing neutral position and clarified the three-dimensional angular rotations of the upper extremity joints.

Methods: Computed tomography (CT) images of 158 upper extremities from 79 healthy volunteers were prospectively acquired in the standing neutral position using an upright CT scanner.

[Successful treatment of multiple pulmonary metastases of adenoid cystic carcinoma of the external auditory meatus with TS-1].

The patient, a 67-year old man, was referred to us with refractory otorrhea of the left ear. The diagnosis was adenoid cystic carcinoma of the external auditory meatus, so the primary focus was excised. During the postoperative observation period, multiple metastases to the lung were noted, for which TS-1 (120 mg/day, given for 28 consecutive days, each course followed by a discontinuation of 14 days) was administered.
