Recurrent treatment-refractory brain metastases can be treated with modern adjuvant therapies such as laser interstitial thermal therapy (LITT). Since previously radiated lesions may be indolent (treatment effect) or recurrent tumor, histological confirmation may be helpful. The authors present the utility of contemporaneous biopsy and LITT using intraoperative O-arm navigation in a patient who presented with multiple refractory metastases. The authors demonstrate the utility of O-arm navigation to confirm intraoperative biopsy and LITT placement. Concurrent stereotactic biopsy and LITT may be a safe and efficacious method for both the diagnosis and treatment of deep lesions that are unamenable to standard adjuvant treatment modalities.

The authors report on the first surgical treatment for traumatic interspinous ligament calcification, with significant radiographic and symptomatic improvements at long-term follow-up. Heterotopic ossification occurs following traumatic injury but does not typically affect the interspinous ligaments. While these ligaments can calcify with age, this is rarely seen in patients younger than 50 years of age. The authors present the unusual case of a 31-year-old man who suffered traumatic fractures of thoracic and lumbar spinous processes. He developed progressive low-back pain that failed to respond to conservative treatments. At presentation, he was neurologically intact. CT scanning demonstrated partial calcification of the interspinous ligaments at L2–3, L3–4, and L4–5 with significant hypertrophy of the spinous processes at those levels. He did not have significant disc pathology, and his symptoms were attributed to the limited range of motion caused by the enlarged spinous processes. Partial resection of the spinous processes and calcified interspinous ligaments was performed to remove the heterotopic bone. The patient was seen in follow-up at 5 months postoperatively for imaging, and he was interviewed at 1 and 2 years postoperatively. He is doing well with significant pain relief and an improved range of motion. His Oswestry Disability Index improved from 25 preoperatively to 18 at 2 years postoperatively.
