Case Reports
Rupture of the spleen following thoracoscopic spine surgery in a patient with chronic pancreatitis.
To highlight the perioperative risk of intracapsular haematoma of the spleen or splenic ruptures during thoracoscopic spine surgery in patients with chronic pancreatitis. ⋯ Due to its proximity to the thoracolumbar junction, the spleen is vulnerable to injury during spine surgery. If the patient has undergone previous intra-abdominal operations or chronic inflammation of the pancreas is found, special care of the spleen during the operation is necessary.

We report on a patient with an unusual cause of non-discogenic sciatica. ⋯ The present case suggested that an intrapiriformis lipoma can cause secondary piriformis syndrome and medical practitioners should be aware of this condition and consider lipomas and other occupying lesions of the pelvic muscles as a differential diagnosis in patients presenting with radicular pain.

Retro-odontoid synovial cysts are rare and attributable to degenerative changes in the atlantoaxial joints. An anterolateral approach facilitates access to lesions located anterior to the craniocervical junction without harming the atlantoaxial joints, and can also treat small lesions in the ventral mid-portion of the craniocervical junction without compression of spinal cord. ⋯ The anterolateral approach for the retro-odontoid synovial cyst had little effect on C1-2 instability and yielded neurological improvements.

To report the results of coccygectomy for coccygeal spicule. ⋯ Surgical treatment for coccygeal spicules that are causing coccygodynia and are resistant to conservative treatment gives satisfactory outcomes, similar to those obtained from surgery for instability of the coccyx.

Case Reports
Nontraumatic posterior atlantooccipital dislocation associated with atlantoaxial instability.
Nontraumatic posterior atlantooccipital dislocation has only been rarely reported. In the current study, the authors reported an extremely rare case of nontraumatic posterior atlantooccipital dislocation associated with atlantoaxial instability. ⋯ To our knowledge, this lesion has not been reported previously. Anomalies of upper cervical spine may have induced this instability.
