ABSTRACT

Thoracic ossification of the posterior longitudinal ligament (OPLL) is a rare condition that is mainly accompanied by cervical OPLL or ossification of thoracic ligamentum flavum. In case of causing neurological manifestations, it is preferred to treat the condition surgically. Several surgical procedures were introduced, including anterior, posterior, or combined approaches. Laminectomy with instrumented fusion is the most popular procedure utilized via the posterior approach. A 32-year-old obese woman, who suffered from back pain and weakness in both lower extremities for one month, was referred to our spine outpatient clinic. Imaging revealed lower thoracic OPLL (T7/T8 & T8/T9 & T9/T10). The posterior longitudinal ligament had a mixed ossification pattern (beaked and continuing cylindrical). To maintain thoracic spine stability and prevent future kyphosis, we performed laminectomy and long segment fixation (T7 to T12). The post-operative neurological examination revealed a considerable increase in muscle strength and significant pain relief.

ABSTRACT

Background: Solitary plasmacytoma (SP) caused the collapse/destruction of the C2 vertebral body in a 78-year-old male. To provide sufficient posterior stabilization, the patient warranted lateral mass fusion to supplement the bilateral pedicle/screw rod instrumentation. Case Description: A 78-year-old male presented with neck pain alone. X-rays, computed tomography, and magnetic resonance studies documented C2 vertebral collapse with the complete destruction of both lateral masses. The surgery required a laminectomy (i.e., bilateral lateral mass resection), plus placement of bilateral expandable titanium cages from C1 to C3 to supplement the screw/rod occipitocervical (O-C4) fixation. Adjuvant chemotherapy and radiotherapy were also administered. Two years later, the patient remained neurologically intact and radiographically had no evidence of tumor recurrence. Conclusion: In patients with vertebral plasmacytomas and bilateral lateral mass destruction, posterior occipital-cervical C4 rod/screw fusions may warrant the additional bilateral placement of titanium expandable lateral mass cages from C1 to C3.
