A peroneal dislocation is a rare disease that is often misdiagnosed as a simple sprain and can be treated inadequately in the acute phase.For this reason, it is important to have an appropriate diagnosis in the early stages because it can progress to chronic and recurrent conditions. Surgical treatment is considered mainly when progressing to chronic recurrent dislocation. Recently, patients with an acute peroneal dislocation tend to prefer surgical treatment, so accurate initial diagnosis and management are very important. This paper reports a case of chronic recurrent peroneal tendon dislocation in both ankle joints, which was treated by a superior peroneal retinaculum reconstruction and a groove deepening procedure.

PURPOSE:
To determine if sparing the interspinous and supraspinous ligaments during posterior decompression for lumbar spinal stenosis is significant in preventing postoperative spinal instability.
MATERIALS AND METHODS:
A total of 83 patients who underwent posterior decompression for lumbar spinal stenosis between March 2014 and March 2017 with a minimum one-year follow-up period, were studied retrospectively. The subjects were divided into two groups according to the type of surgery. Fifty-six patients who underwent posterior decompression by the port-hole technique were grouped as A, while 27 patients who underwent posterior decompression by a subtotal laminectomy grouped as B. To evaluate the clinical results, the Oswestry disability index (ODI), visual analogue scale (VAS) for both back pain (VAS-B) and radiating pain (VAS-R), and the walking distance of neurogenic intermittent claudication (NIC) were checked pre- and postoperatively, while simple radiographs of the lateral and flexion-extension view in the standing position were taken preoperatively and then every six months after to measure anteroposterior slippage (slip percentage), the difference in anteroposterior slippage between flexion and extension (dynamic slip percentage), angular displacement, and the difference in angular displacement between flexion and extension (dynamic angular displacement) to evaluate the radiological results.
RESULTS:
The ODI (from 28.1 to 12.8 in group A, from 27.3 to 12.3 in group B), VAS-B (from 7.0 to 2.6 in group A, from 7.7 to 3.2 in group B), VAS-R (from 8.5 to 2.8 in group A, from 8.7 to 2.9 in group B), and walking distance of NIC (from 118.4 m to 1,496.2 m in group A, from 127.6 m to 1,481.6 m in group B) were improved in both groups. On the other hand, while the other radiologic results showed no differences, the dynamic angular displacement between both groups showed a significant difference postoperatively (group A from 6.2° to 6.7°, group B from 6.5° to 8.4°, p-value=0.019).
CONCLUSION
Removal of the posterior ligaments, including the interspinous and supraspinous ligaments, during posterior decompression of lumbar spinal stenosis can cause a postoperative increase in dynamic angular displacement, which can be prevented by the port-hole technique, which spares these posterior ligaments.

PURPOSE: To describe the technical skills and to estimate the clinical outcomes of port-hole decompression preserving the posterior ligaments during lumbar spinal stenosis surgery. MATERIALS AND METHODS: Between March 2014 and March 2016, a total of 101 patients who underwent port-hole decompression were retrospectively analyzed. The mean age was 71.3 years (58–84 years) and there were 46 males and 55 females. The mean follow-up period was 18 months. Degenerative spondylolisthesis was observed in 24.8% of patients (25/101). Port-hole decompression was performed by removing the central portion of the distal part of the upper lamina with a burr. Then, the contralateral side of ligamentum flavum and hypertrophied facet joints were removed. We estimated the lumbar lordotic angle using radiographs, and measured the depth from skin to upper lamina central area using magnetic resonance imaging axial images. We estimated the mean slip angle and mean degree of slip in preoperative and postoperative radiography in standing flexion and extension. We also measured the operational time, length of skin incision, and blood loss. The clinical results were estimated by a walking distance caused by neurologic intermittent claudication, visual analogue scale, and Oswestry disability index. RESULTS: Most patients were generally older, and the mean lordotic angle was 25.3°, which is considered to be lower when compared with younger people. The mean depth from skin to lamina was mean 5.4 cm. With respect to the radiological results, there were no significant differences between the preoperative and postoperative groups. The operation time, length of skin incision, and bleeding were not increased proportionally to the operation level. The walking distance caused by neurologic intermittent claudication, visual analogue scale, and Oswestry disability index of the post-operative group were all improved compared with the pre-operative group. CONCLUSION: The port-hole decompression, which decompresses the contralateral side while preserving the posterior ligaments and facet joints may be a useful technique for elderly patients with multiple level stenosis, minimizing spinal segmental instability.

PURPOSE: To analyze the result of a repeat discectomy for ipsilateral recurrent lumbar disc herniation and to investigate the potential factors that influenced the outcomes for this surgery. MATERIALS AND METHODS: Fifty-nine patients, who underwent reoperation after lumbar discectomy with a minimum follow-up period of 2 years, were reviewed. The surgical outcome was assessed using the visual analogue scale (VAS) and Macnab classification, and the recovery rate was calculated in accordance with VAS. A statistical analysis was carried out by SPSS to evaluate the possible factors that may have influenced the outcomes of the reoperation. RESULTS: The rate of reoperation after lumbar disc surgery due to the recurrent disc herniation was 6.0% (59/983 cases). The average recovery rate of VAS from the 1st operation was approximately 77%, and from the 2nd operation was 71%. According to the Macnab criteria, the results were “excellent” or “good” in 96% of cases. Statistical analysis revealed that there was no difference of the average recovery rate (p<0.05). There is no additional instability after repeat discectomy. Factors, such as smoking, precipitating traumatic events, and diabetes mellitus did not have much influence on the average recovery rate after repeat discectomy for ipsilateral recurrent lumbar disc herniation. CONCLUSION: The outcomes of repeat discectomy were satisfactory. Moreover, factors, smoking, trauma history and diabetic mellitus, only had a minor impact on the outcomes of a repeat discectomy.

BACKGROUND: The development of pedicle screw-based posterior spinal instrumentation is recognized as one of the major surgical treatment methods for thoracolumbar burst fractures. However, the appropriate level in posterior segment instrumentation is still a point of debate. To assesses the long-term results of two-level and three-level posterior fixations of thoracolumbar burst fractures that have load-sharing scores of 7 and 8 points. METHODS: From January 1998 to May 2009, we retrospectively analyzed clinical and radiologic outcomes of 45 patients with thoracolumbar burst fractures of 7 and 8 points in load-sharing classification who were operated on using two-level posterior fixation (one segment above and one segment below: 28 patients, group I) or three-level posterior fixation (two segments above and one segment below: 17 patients, group II). Clinical results included the grade of the fracture using the Frankel classification, and the visual analog score was used to evaluate pain before surgery, immediately after surgery, and during follow-up period. We also evaluated pain and work status at the final follow-up using the Denis pain scale. RESULTS: In all cases, non-union or loosening of implants was not observed. There were two screw breakages in two-level posterior fixation group, but bony union was obtained at the final follow-up. There were no significant differences in loss of anterior vertebral body height, correction loss, or change in adjacent discs. Also, in clinical evaluation, there was no significant difference in the neurological deficit of any patient during the follow-up period. CONCLUSIONS: In our study, two-level posterior fixation could be used successfully in selected cases of thoracolumbar burst fractures of 7 and 8 points in the load-sharing classification.

STUDY DESIGN: A retrospective comparative study. OBJECTIVES: To compare the outcome of percutaneous vertebroplasty (VP) and conservative treatment for the treatment of acute painful osteoporotic vertebral compression fractures (VCF). SUMMARY OF LITERATURE REVIEW: Vertebroplasty is a common procedure for the treatment of acute painful osteoporotic VCF. However, controversy still exists regarding clinical outcomes of the procedure compared with more conservative treatment. MATERIAL AND METHODS: A consecutive group of patients, undergoing VP and conservative treatment at our hospital, between July 2005 and October 2008, were reviewed retrospectively. All patients were reviewed with at least 1 year of follow up. A total of 58 patients underwent 59 VP procedures under local anesthesia at post injury 2 weeks; a total of 31 underwent conservative treatment. These two groups were compared by the kyphotic angle and loss of vertebral body height at immediate post-injury, post-injury 6weeks and 1y ear, radiologically. And they were compared by the visual analog scale(VAS) score and ambulatory status at the same time, clinically. RESULTS: At the time of immediate post-injury, six weeks after post-injury, one year after injury, height loss was 29.73%, 19.81%, 22.59% in the VP group, respectively, and 31.20%, 36.80%, 40.60% in the conservative treatment group, respectively. The Kyphotic angles were 13.44degrees, 9.10degrees, 11.31degrees in VP group, respectively, and 10.29degrees, 15.83degrees, 19.00degrees in the conservative treatment group, respectively. There was a statistically significant reduction of height loss and kyphotic angle in VP group at post-injury of 6 weeks and 1 year(p<0.05). At the same time, VAS scores were 9.41, 4.32, 2.47 in the VP group, respectively, and 9.50, 6.25, 2.71 in conservative treatment group, respectively. Ambulation status was 3.61, 1.46, 1.22 in the VP group, respectively, and 3.65, 2.45, 1.32 in the conservative treatment group, respectively. There was a statistically significant reduction of VAS score and improved ambulation status in VP group at post-6 weeks, but no difference between two groups at post 1 year. There was no significant difference in new fractures of adjacent vertebrae between the two groups (p>0.05). CONCLUSIONS: VP prevents further collapse and kyphosis relieves pain quickly and allows early ambulation, but in post-injury 1 year follow up, there was no significant difference in clinical outcomes. Proper treatment should be done with respect to patient's age, general condition, economic status and complication.

STUDY DESIGN: A retrospective comparative analysis of the short-segment and long-segment posterior fixation in thoracolumbar burst fractures that are 7 points or above in load-sharing score was performed. OBJECTIVES: The purpose of this study is to demonstrate the appropriate level of fixation by comparing the results of short-segment and long-segment posterior fixation. SUMMARY OF LITERATURE REVIEW: There is general consensus that short-segment fixation should be done in thoracolumbar burst fractures that are 6 points or less in load-sharing classification. There is some controversy regarding whether short-segment or long-segment fixation should be done in thoracolumbar burst fractures that are 7 points or above in load-sharing classification. MATERIALS AND METHODS: From 1998 through 2008, 32 patients with thoracolumbar burst fractures above 7 points in load-sharing classification had been operated with short-segment (1 segment above and 1 segment below: 23 patients) or long-segment (2 segments above and 1 segment below: 9 patients) transpedicular screw fixation at the author's institution. They were divided by two groups (group I: short-segment fixation, group II: long-segment fixation). The mean age of patients was 49.2 years old and the mean follow-up period was 2.4 years (1-7 years). In preoperative and postoperative simple radiographs, the bony unions, breakages or loosening of implants were assessed, and the losses of correction angle and anterior vertebral body height were measured. RESULTS: In all cases, non-union or loosening of implants were not observed. There was 1 screw breakage in short-segment fixation group during the follow up period, but bony union was obtained at final follow-up. The mean score of load sharing classification was 7.3 in Group I and 7.1 in Group II, and there was no significant difference between two groups. (p>0.05) The mean anterior vertebral body height loss was 5.3% in Group I and 3.6% in Group II and the mean loss of correction angle were 4.72 in Group I and 3.38 in Group II. There was no significant difference between the two groups for both. (p>0.05) CONCLUSIONS: There was no significant difference in radiologic parameters between two groups. Short-segment fixation could be used successfully in selected cases of thoracolumbar burst fractures that are 7 points or above in load-sharing classification.

A 17-year-old male patient complained of acutely developed severe paresthesia, pain, and weakness of the right lower extremity. He fell to the ground during performance of hand-stand physical exercise. Despite administration of conservative treatment for two weeks in a private clinic, motor function of the hip flexor and knee extensor were measured as poor grade. EMG showed femoral nerve and lateral femoral cutaneous nerve injury. Findings on MRI and CT revealed a mass measuring 8x5x7 cm in the iliac fossa. After evacuation of the hematoma(400 cc), neurologic dysfunction and thigh circumference were fully recovered, compared with the contralateral side, after one and half year follow up. This condition rarely occurs in individuals without coagulopathy. We reported on a rare case of iliacus hematoma and femoral neuropathy treated by surgical decompression in a patient with no coagulopathy.

A spontaneous rupture of the extensor pollicis longus (EPL) tendon is associated with rheumatoid arthritis, fractures of the wrist, systemic or local steroids and repetitive, and excessive abnormal motion of the wrist joint. The authors encountered a case of a spontaneous rupture of the EPL tendon. The patient had no predisposing factors including trauma or steroid injection. Although the patient had a positive rheumatoid factor, he did not demonstrate other clinical or radiological findings of rheumatoid arthritis. During surgery, the EPL tendon was found to be ruptured at the extensor retinaculum (third compartment). Reconstruction of the extensor tendon using the palmaris longus tendon was performed. At the 18-month follow-up, the patient showed satisfactory extension of the thumb and 40degrees extension and flexion at the wrist.

STUDY DESIGN: A prospective radiological assessment. OBJECTIVES: Changes in the height, area, and width--captured using computed tomography (CT)--of the neural foramen with respect to changes in the intervertebral disc height, after undergoing an anterior cervical disc removal and fusion procedure. SUMMARY OF LITERATURE REVIEW: The multiple authors of this study, by obtaining central canal and area of neural foramen by increasing the disc spacing height and area of the neural foramen, attempted to assess the height increase of disc spacing. It is necessary to consider the synergistic effects of decompression through dissection of the posterior longitudinal ligament (PLL). MATERIALS AND METHODS: The authors studied 17 patient cases that underwent one segment anterior cervical discectomy and fusion (ACDF) for degenerative cervical disease from June 2006 to March 2007. All patient cases underwent autogenous iliac bone graft or cage insertion with plate fixation procedure. We measured the areas of the neural foramen, heights of the vertebra body above and below the removed intervertebral disc with CT before and after ACDF. Radiographic measurements were averaged. RESULTS: Among the 17 cases, the height of the cervical disc increased in 15 cases and decreased in 2 cases. The heights of the neural foramen increased in 19 cases and showed no changes in 13 cases. The areas of the neural foramen increased in 23 cases and decreased in 6 cases. The heights of vertebral body above and below the removed disc increased by 5.4% (p=0.734), and the heights of the neural foramen increased by 13.3% (p=0.002). The area of the neural foramen increased by 13.6% (p=0.192). The widths of the neural foramen increased by 2.3% (p=0.586). The intervertebral disc height, neural foramen height, and neural foramen area increased by 39.6%, 8.4%, and 17.9%, respectively, after a 2mm lengthening of bone transplant. The intervertebral disc height, neural foramen height, and neural foramen area increased by 59.8%, 22.9%, and 10.3%, respectively, after a 3mm lengthening of bone transplant. The height and area of neural foramen increased by 18.3% and 18.2%, respectively, after the PLL removal and dissection. CONCLUSIONS: The follow-up observations of the intervertebral disc height, neural foramen height, and neural foramen area showed increases after one segment ACDF in cervical disease cases, when compared to the preoperative radiographic findings. As the height of bone transplant increased, the intervertebral disc height, neural foramen height, and neural foramen area increased. The neural foramen height and neural foramen area significantly increased, when PLL was dissected.
