Introduction: Spinal osteochondroma is rare. The purpose
of this study is to examine the clinical characteristics and
surgical treatment outcomes of 11 patients with spinal
osteochondroma.
Materials and methods: The study included 11 patients
with spinal osteochondroma. In these patients, we examined
the onset level, onset site, initial symptoms, surgical
procedure, outcomes and complications.
Results: Of the 11 patients, 9 presented with solitary
tumours, and 2 had multiple. The mean post-operative
observation period was six years and two months. The onset
level was the cervical spine in eight patients, thoracic in two,
and lumbar in one. The most common onset site was the
posterior elements. The initial presentation was myelopathy
in seven patients, radiculopathy in two, neck pain in one and
feeling of mass in one. All patients underwent excision of the
tumour, and depending on the tumour onset site, additional
posterior or anterior decompression with or without fusion
was performed. There was no recurrence in all patients.
Intra-operative complications included dura tear and
oesophageal injury in one patient with cervical onset, while
post-operative complications included C5 palsy in one
patient.
Conclusions: In this study, surgical excision for
osteochondroma of the spine were excellent with no
recurrence of the tumour.
