Microendoscopic Excision of Osteoid Osteoma in the Pedicle of the Third Lumbar Vertebra.
We present a rare case of a patient who underwent complete microendoscopic excision of an osteoid osteoma, which induced radiculopathy without nerve root compression. A 20-year-old man presented severe right groin pain that was temporarily relieved by nonsteroidal anti-inflammatory drugs. A computed tomography (CT) scan showed typical features of a nidus located in the inferior cortex of the right L3 pedicle. We performed surgery using a posterior microendoscopic approach. We drilled vertically along the line of the cortex of the caudal pedicle using a high-speed drill. After identifying the tumor, en bloc resection of the...

Ultra Long Construct Minimally Invasive Spinal Stabilization Using Percutaneous Pedicle Screws in the Treatment of Symptomatic Multicentric Spinal Metastasis.
We report the case of a 58-year-old female with advanced lung cancer who presented with multiple pathological fractures of the thoracic spine (T5, T6, T7, and T8 vertebrae). She was treated with palliative radiotherapy. Her resting pain improved, but the instability pain persisted. One month later, she had a trivial fall leading to a pathological fracture of the L2 vertebra with cauda equine syndrome. The patient was treated surgically with minimally invasive decompression of the L2 and with percutaneous instrumented stabilization using an ultra-long construct from T3 to L5 (15 spinal levels), spanning the previously radia...

Combined Type II Odontoid Fracture with Jefferson's Fracture Treated with Temporary Internal Fixation.
Authors: Pawar AY, O'Leary PF Abstract An 18-year-old male presented after a motor vehicle rollover accident. Computed tomography (CT) scan confirmed the diagnosis of Type II odontoid fracture. Considering the patient's young age and the limitations of C1-C2 fusion including significant loss of cervical rotation, temporary internal fixation with a lateral mass fixation of C1 and pedicle fixation of C2 without fusion was done. CT scan done at 6-month follow-up visit showed healed odontoid fracture and excellent C1-C2 alignment. At ninth postoperative month, internal fixation was removed. Patient had normal movements...

Management of Sacral Tumors Requiring Spino-Pelvic Reconstruction with Different Histopathologic Diagnosis: Evaluation with Four Cases.
Authors: Arıkan M, Togral G, Hasturk AE, Kekec F, Parpucu M, Gungor S Abstract In this retrospective study, surgical results of four patients with sacral tumors having disparate pathologic diagnoses, who were treated with partial or total sacrectomy and lumbopelvic stabilization were abstracted. Two patients were treated with partial sacral resection and two patients were treated with total sacrectomy and spinopelvic fixation. Fixation methods included spinopelvic fixation with rods and screws in two cases, reconstruction plate in one case, and fresh frozen allografts in two cases. Fibular allografts used for reco...

Lateral Lumbar Interbody Fusion.
Authors: Pawar A, Hughes A, Girardi F, Sama A, Lebl D, Cammisa F Abstract The lateral lumbar interbody fusion (LLIF) is a relatively new technique that allows the surgeon to access the intervertebral space from a direct lateral approach either anterior to or through the psoas muscle. This approach provides an alternative to anterior lumbar interbody fusion with instrumentation, posterior lumbar interbody fusion, and transforaminal lumbar interbody fusion for anterior column support. LLIF is minimally invasive, safe, better structural support from the apophyseal ring, potential for coronal plane deformity correction...

The Concept of Evolution of Thoracolumbar Fracture Classifications Helps in Surgical Decisions.
Authors: Azam MQ, Sadat-Ali M Abstract Since Boehler's sentinel description, a universally acceptable thoracolumber fracture classification has eluded spine surgeons. The concept of the stability of a thoracolumbar injury changed continuously from the two column concept of Holdsworth to the three column theory of Denis. With the advent of sophisticated imaging techniques, improved biomechanical understanding, and in order to meet the high expectations of patients, several classification systems have been forwarded by the stalwarts in the field. Each successive system has contributed significantly to the understandi...

Surgical Excition of Spinal Intradural Meningiomas through a Single-Sided Minimally Invasive Approach: Key-Hole Laminotomy.
CONCLUSIONS: Total resection of anterior and anterolateral IDEM menengiomas, without introducing new neurological deficits, can be performed by an isolated posterior approach through a single-sided keyhole laminotomy. However, this approach should be applied cautiously and with a thorough understanding of its limitations. PMID: 25901234 [PubMed] (Source: Asian Spine Journal)

Risk factors for adjacent segment disease development after lumbar fusion.
CONCLUSIONS: Patients with postoperative sagittal imbalance have a statistically significant increased risk of developing symptomatic ASD due to an overloading the adjacent segments and limited compensatory capacities due to the large number of fixed mobile segments. In the case of a short fixation, preoperative degenerative changes are more important factors in the development of ASD. PMID: 25901236 [PubMed] (Source: Asian Spine Journal)

A Retained Epidural Catheter Fragment Treated by Surgery.
We describe a unique case where a retained epidural catheter fragment after epidural anesthesia was treated by surgery. The epidural catheter broke during its removal, requiring surgery to remove the retained catheter. Intraoperatively, the removal of the catheter was attempted by simple traction, but was impossible because of the adhesion. The adhesion of the dura mater surface was carefully exfoliated and the successful removal of the catheter was accomplished. Conventionally, it was said that this follow-up was enough for the retained catheter. However, if a catheter is retained within the spinal canal, surgical removal...
