Patient safety regarding wrong site surgery has been one of the priority issues in surgical fields including that of spine care. Since the wrong-side surgery in the DM foot patient was reported on a public mass media in 1996, the wrong-site surgery issue has attracted wide public interest as regarding patient safety. Despite the many wrong-site surgery prevention campaigns in spine care such as the operate through your initial program by the Canadian Orthopaedic Association, the sign your site program by the American Academy of Orthopedic Surgeon, the sign, mark and X-ray program by the North American Spine Society, and the Universal Protocol program by the Joint Commission, the incidence of wrong-site surgery has not decreased. To prevent wrong-site surgery in spine surgeries, the spine surgeons must put patient safety first, complying with the hospital policies regarding patient safety. In the operating rooms, the surgeons need to do their best to level the hierarchy, enabling all to speak up if any patient safety concerns are noted. Changing the operating room culture is the essential part of the patient safety concerning spine surgery.

Asian Spine Journal.2013;7(1):60-62. doi:10.4184/asj.2013.7.1.60

Lumbar disc herniation (LDH) associated with a contralateral neurological deficit is sometimes encountered by surgeons. Compression against the opposite pedicle in case of a large discal herniation and prominent stenotic changes of contralateral side are held responsible for contralateral symptoms and findings. In this study, we report a case of LDH associated with a painless contralateral neurological deficit. Prominent venous engorgement and congestion at the contralateral side of discal herniation were detected during the operation. It's treatment with bipolar coagulation and significant improvement was seen after the operation.

Mohammad Ibrahim BADRA ; Richard ASSAKER ; Ramzi Sharif MUSHARRAFIEH

Asian Spine Journal.2013;7(1):55-59. doi:10.4184/asj.2013.7.1.55

Proximal junctional disease is a well-recognized postoperative phenomenon in adults who are undergoing long thoracolumbar fusion and instrumentation, and is attributed to increased a junctional stress concentration. In general, the onset of symptoms in these patients is insidious and the disease progresses slowly. We report on a contrary case of rapidly progressing paraplegia secondary to acute disc herniation at the proximal adjacent segment after long posterior thoracolumbar fusion with cement augmentation at the upper instrumented vertebra and the supra-adjacent vertebra. The patient was treated with a discectomy through the costo-transverse approach combined with extension of the posterior instrumentation. The patient's neurological status improved markedly. Stress concentration at the proximal junction disc space may have caused accelerated disc degeneration which in turn lead to this complication.

Spinal dermoid tumors are rare, benign, slow growing tumors. These tumors may become acutely symptomatic after rupture or infection. Excision of the lesion with long term close follow-up studies is required for the management of these lesions. We present a very rare case of ruptured conus medullaris dermoid cyst in a 22-year-old male presented with urinary retention and low back pain. Magnetic resonance imaging scan with contrast reveals a lesion in the cauda equina inseparable from conus medullaris with fat droplets within the central spinal canal extending up to the medulla. Patient was operated with laminectomy and near complete excision of the lesion was done. Patient's low back pain was relieved following surgery. However patient had persistent urinary incontinence and on clean intermittent self-catheterization. Histopathology was suggestive of dermoid cyst.

Francis Hao Tso SHEN ; Dino SAMARTZIS

Asian Spine Journal.2013;7(1):44-49. doi:10.4184/asj.2013.7.1.44

Gunshot wounds to the spine account for 13% to 17% of all gunshot injuries and occur predominantly in the thoracic region. Minimally invasive spine surgery procedures implementing serial muscle dilation and the use of a tubular retracting system with a working channel minimize soft tissue trauma, facilitate less bony and soft tissue resection, decrease blood loss, minimize scarring and improve cosmesis, decrease hospitalization, and reduce postoperative pain and narcotic usage in comparison to more open, traditional approaches. Although minimally invasive spine surgery techniques and instrumentation have gained considerable attention, their application in the management of gunshot injuries to the sacrum has not been reported. The following is a brief case report of a 21-year-old male who sustained a gunshot injury to the sacrum who was managed operatively via minimally invasive spine surgery techniques and instrumentation.

Spinal hydatid cyst is a rare occurrence in non endemic countries. We present a case of recurrent lumbar hydatid disease in a 21-year-old male who following initial treatment had a good functional outcome and healing for 8 years, following which he came back with complaints of low back ache and neurological deficit. Patient underwent a second surgery with global debridement of L3-L5 vertebrae followed by medical management for two years. He had a good surgical outcome with recovery from the neurological deficit. Patient has returned to his routine activities and is being reviewed every year; there is no evidence of recurrence in the past 3 years. To the best of our knowledge recurrence after 8 years of initial treatment, followed by good clinical and radiological outcome for 3 years after surgery and treatment of the recurrence has not been reported in literature.

Asian Spine Journal.2013;7(1):34-38. doi:10.4184/asj.2013.7.1.34

STUDY DESIGN: Retrospective analysis. PURPOSE: To evaluate the effectiveness of anterior cervical discectomy with fusion for degenerative cervical disc disease. OVERVIEW OF LITERATURE: Anterior spinal surgery originated in the mid-1950s and graft for fusion was also employed. Currently anterior cervical microdiscectomy and fusion with an intervertebral cage is a widely accepted procedure for treatment of cervical disc hernia. Artificial grafts and cages for fusion are preferred because of their lower morbidity, reduced operating time and acceptable fusion rate. METHODS: The study involved retrospective analysis and investigation of long-term results for 41 consecutive patients who had undergone anterior cervical discectomy and fusion with an intervertebral cage for cervical disc hernia. The angle of lordosis, segmental height and range of motion were evaluated preoperatively and postoperatively at 1 month and 2 years. The clinical outcome was assessed by the visual analog scale and Odom's criteria. RESULTS: The angle of lordosis increased by 2.62degrees and the range of motion angle increased by 5.14degrees after the operation. The segmental height did not change. The visual analog scale and Odom's criteria scores decreased significantly after the operation. CONCLUSIONS: Using a cage in anterior cervical discectomy prevents segmental collapse, so the segmental height and the angle of lordosis are preserved and newly-developed pain does not occur.

Asian Spine Journal.2017;11(4):580-585. doi:10.4184/asj.2017.11.4.580

STUDY DESIGN: Cross-sectional. PURPOSE: To examine the relationship between magnetic resonance imaging (MRI) morphology stenosis grades and preoperative walking ability in patients with lumbar canal stenosis (LCS). OVERVIEW OF LITERATURE: No previous study has analyzed the correlation between MRI morphology stenosis grades and walking ability in patients with LCS. METHODS: This prospective study included 98 consecutive patients with LCS who were candidates for surgery. Using features identified in T2-weighted axial magnetic, stenosis type was determined at the maximal stenosis level, and only trefoil and triangle stenosis grade types were considered because of sufficient sample size. Intraobserver and interobserver reliability were assessed by calculating weighted kappa coefficients. Symptom severity was evaluated via the Japanese Orthopedic Association Back Pain Evaluation Questionnaire (JOABPEQ). Walking ability was assessed using the Self-Paced Walking Test (SPWT) and JOABPEQ subscales. Demographic characteristics, SPWT scores, and JOABPEQ scores were compared between patients with trefoil and triangle stenosis types. RESULTS: The mean patient age was 58.1 (standard deviation, 8.4) years. The kappa values of the MRI morphology stenosis grade types showed a perfect agreement between the stenosis grade types. The trefoil group (n=53) and triangle group (n=45) showed similar preoperative JOABPEQ subscale scores (e.g., low back pain, lumbar function, and mental health) and were not significantly different in age, BMI, duration of symptoms, or lumbar stenosis levels (all p>0.05); however, trefoil stenosis grade type was associated with a decreased walking ability according to the SPWT and JOABPEQ subscale scores. CONCLUSIONS: These findings suggest preoperative walking ability is more profoundly affected in patients with trefoil type stenosis than in those with triangle type stenosis.

Radiologic and Clinical Courses of Degenerative Lumbar Scoliosis (10°–25°) after a Short-Segment Fusion.

Kyu Yeol LEE ; Min Woo KIM ; Chul Soon IM ; Young Hoon JUNG

Asian Spine Journal.2017;11(4):570-579. doi:10.4184/asj.2017.11.4.570

STUDY DESIGN: Retrospective study. PURPOSE: We report the surgical outcomes of small degenerative lumbar scoliosis (DLS) patients treated by a short-segment fusion and followed for a minimum of 5 years. OVERVIEW OF LITERATURE: Several surgical options are available for the treatment of DLS, such as decompression only, decompression plus a short-segment fusion, or decompression with a long segment fusion. Few studies have evaluated the results of a short-segment fusion in patients with DLS over time. METHODS: Seventy small DLS patients (Cobb's angle, 10°–25°) with a minimum follow-up of 5 years were treated with a short-segment fusion between March 2004 and February 2010. The mean patient age was 71 (male:female=16:54), with a follow-up of 6.5 years (range, 5.0–11.6). The Cobb's angle, 1 and 2 segment coronal upper intervertebral angle, 1 and 2 segment sagittal upper intervertebral angle, the lumbar lordosis angle, and the C7 plumb lines (coronal and sagittal) were evaluated using simple radiographs, and visual analog scale (VAS), back pain was assessed preoperatively, immediately after surgery, and at 3, 6, and 12 months and 3 and 5 years after surgery. To identify factors influencing the radiologic progression, age, number of fusion segments, vertebral levels of fusion, body mass index, lowest instrumented vertebra (L5 or S1), bone mineral density (>–2.5, ≤–2.5), and the presence of an interbody fusion were analyzed. RESULTS: The Cobb's angle and 1 segment coronal upper intervertebral angle showed more progression during follow up, particularly at 6 and 12 months after surgery. Clinical outcomes and radiological results were found to be significantly associated (p=0.041). No statistically significant association was found between other factors affecting radiologic progression from postoperative 6 months to 1 year. CONCLUSIONS: Radiologic variables (the Cobb's angle and coronal upper intervertebral angle–1) should be carefully considered and clinical caution exercised from 6 to 12 months after short-segment fusion in small DLS (10°–25°).

Asian Spine Journal.2017;11(4):562-569. doi:10.4184/asj.2017.11.4.562

STUDY DESIGN: In vivo biomechanical study using a three-dimensional (3D) musculoskeletal model for elderly individuals with or without pelvic retroversion. PURPOSE: To evaluate the effect of pelvic retroversion on the sagittal alignment of the spine, pelvis, and lower limb in elderly females while standing and walking. OVERVIEW OF LITERATURE: Patients with hip–spine syndrome have concurrent hip-joint and spine diseases. However, the dynamic sagittal alignment between the hip joint and spine has rarely been investigated. We used a 3D musculoskeletal model to evaluate global spinopelvic parameters, including spinal inclination and pelvic tilt (PT). METHODS: A total of 32 ambulant females (mean age=78 years) without assistance were enrolled in the study. On the basis of the radiographic measurement for PT, participants were divided into the pelvic retroversion group (R-group; PT≥20°) and the normal group (N-group; PT<20°). A 3D musculoskeletal motion analysis system was used to analyze the calculated value for the alignment of spine, pelvis, and lower limb, including calculated (C)-PT, sagittal vertical axis (C-SVA), pelvic incidence, lumbar lordosis, T1 pelvic angle (C-TPA), as well as knee and hip flexion angles while standing and walking. RESULTS: While standing, C-PT and C-TPA in the R-group were significantly larger than those in the N-group. Hip angle was significantly smaller in the R-group than in the N-group, unlike knee angle, which did not show difference. While walking, C-SVA and C-TPA were significantly increased, whereas C-PT decreased compared with those while standing. The maximum hip-flexion angle was significantly smaller in the R-group than in the N-group. There was a significant correlation between the radiographic and calculated parameters. CONCLUSIONS: The 3D musculoskeletal model was useful in evaluating the sagittal alignment of the spine, pelvis, and leg. Spinopelvic sagittal alignment showed deterioration while walking. C-PT was significantly decreased while walking in the R-group, indicating possible compensatory mechanisms attempting to increase coverage of the femoral head. The reduction in the hip flexion angle in the R-group was also considered as a compensatory mechanism.
