Study Design:Retrospective consecutive case series.Objective:The objective of this case series was to demonstrate the safety of a modified transfacet pedicle–sparing decompression and instrumented fusion in patients with thoracic disc herniations (TDHs).Methods:Consecutive patients undergoing operative management of TDH from July 2007 to December 2011 using a posterior unilateral modified transfacet pedicle–sparing approach were identified. All patients underwent open or minimally invasive modified transfacet pedicle–sparing discectomy and segmental instrumentation with interbody fusion, performed by four different surgeons. Pre- and postoperative visual analog scale (VAS) pain scores, Nurick grade, and American Spinal Injury Association Impairment Scale (AIS) were analyzed from a retrospective chart review. Estimated blood loss and complications were also obtained.Results:Fifty-one patients were included that had operations for TDH. Thirty-nine patients had single level decompression and 12 had multilevel decompression. The total number of levels operated on was 64. Five patients were treated with minimally invasive surgery. A herniated disc level of T11-12 (n = 17) was treated most often. One major complication of epidural hematoma occurred. Minor complications such as malpositioned hardware, postoperative hematoma, wound infection, pseudoarthrosis, and pulmonary complications occurred in a few patients. Follow-up ranged from 1 to 46 months with 1 patient lost to follow-up. From preoperative to final postoperative: mean VAS scores improved from 8.31 to 4.05, AIS in all patients remained stable or improved, and Nurick scores improved from 3 to 2.6 on average. No intraoperative or permanent neurological deficit occurred.Conclusion:In our surgical series, 51 consecutive patients underwent modified transfacet pedicle–sparing approach to TDHs and experienced improvement of functional status as well as improvement of objective pain scales with no neurological complications. The posterior unilateral modified transfacet pedicle–sparing decompression and instrumented fusion approach to the thoracic spine is a safe and reproducible procedure for the treatment of TDHs.

Tophaceous gout has classically been described as an affliction of the extremities. It has however been reported as early as 1947 to involve the spinal column. We report a 63-year-old male, previously scheduled for Anterior Cervical Discectomy and Fusion to correct an existing cervical myelopathy at the C3-C4 spinal level, who presented to the emergency room with progressive weakness of the lower extremities and inability to ambulate for three days. Physical examination suggested a possible worsening of his cervical myelopathy but magnetic resonance imaging (MRI) findings remained unchanged from comparison studies. On the day of surgery, he became febrile and complained of excruciating back pain and we therefore initiated an infectious etiology workup and obtained a lumbar spine MRI. Results of imaging suggested a lumbar epidural abscess with effacement of the thecal sac. Emergent L4-L5 decompression led to an evacuation of a "chalky" substance, which was sent for pathology evaluation. This patient was diagnosed with tophaceous gout of the lumbar spine upon final pathological review. We aim to present the management of this case and review the literature associated with this diagnosis with the goal of improving the approach taken to diagnose and treat this pathology. KeywOrds: Epidural abscess, Spinal gout, Spinal stenosis, Tophaceous gout, Spinal infection ÖZTofüslü gut, klasik olarak ekstremitelerin hastalığı olarak tanımlanmakla birlikte 1947 yılında omurganın da tutulumu rapor edilmiştir. Bu olgu sunumunda C3-C4 seviyesinde servikal miyelopati nedeniyle anterior servikal diskektomi ve füzyon planlanan ancak acil servise alt ekstremitelerde progresif güç kaybı ve 3 gündür yürüyememe şikayeti ile başvuran 63 yaşında erkek hastayı sunuyoruz. Fizik muayene hastanın servikal miyelopatisinde muhtemel bir ilerlemeyi işaret ediyordu ancak manyetik rezonans görüntüleme (MRG) bulgularında bir değişiklik olmadığı görüldü. Ameliyat günü hastanın ateşi çıktı ve bel ağrısı ön plana çıktı. Bunun üzerine hastada enfeksiyon kaynağı araştırılmaya başlandı ve lomber spinal MRG yapıldı. Görüntülemenin sonucunda lomber spinal epidural apse ve dural kesede bası tesbit edildi. Acil L4-L5 dekompresyon yapıldı ve tebeşir renkli materyal boşaltılarak patolojik inceleme için gönderildi. Patolojik inceleme sonucunda hastada lomber omurgada tofüslü gut tanısı konuldu. Makalemizde bu olgunun yönetimini sunmayı amaçladık ve ilgili literatürü tanı ve tedavideki yaklaşımı kolaylaştırmak için taradık.

Although extremely rare, hemangioblastomas may occur in a purely osseous location. They may resemble vertebral hemangioma. Treatment should include aggressive surgical removal, although arduous, if appropriate. A bilateral lateral extracavitary approach is ideal for complete spondylectomy. With this technique, ventral and dorsal reconstruction of the spine through the same incision is possible.
