Pseudomeningocele After Spine Surgery: 3 cases of different symptoms / 대한척추외과학회지

Pseudomeningocele after spine surgery can cause various symptoms, but it can also be silent. We experienced 3 cases of pseudomeningocele with different symptoms and we analyzed the characteristics of each case. A small pseudomeningocele without connection to the subarachnoidal space can show no symptoms. A pseudomeningocele with a small dural tear and it's abutted on the duramater at a small portion can produce sciatica and limitations of straight leg raising due to adhesion of the cauda equina around the dural tear. In addition, a large pseudomeningocele with a big dural and lamina defect can produce back tenderness furthermore, a patient with such a lesion can have low back pain and leg pain that are aggravated by an increment of abdominal pressure or by impact to the body and even by walking. Pseudomeningocele should be suspected when symptoms recur after spine surgery and especially in the case of dural tear during an operation

High Tibial Osteotomy Fixed with Long-winged Modified Steinmann pin

PURPOSE: To report the clinical and radiological results after high tibial osteotomy that was fixed with a long winged modified Steinmann pin. MATERIALS AND METHODS: Forty knees of twenty patients with genu varum, degenerative or physiologic, underwent high tibial osteotomy using a long-winged modified Steinmann pin and four-week cast immobilization. Mean follow up was 36.0 months(5~67 months). Clinical results were assessed using the Knee society score and radiographic measurements, using Bauer 's method and Insall-Savati ratio. Statistical analyses were performed with the paired samples t-test. RESULTS: The corrected angle was varus 3.2+/-2.7 degrees preoperatively, valgus 7.3+/-2.0 degrees postoperatively(p<0.05), and valgus 6.0+/-1.4 degrees at the latest follow up. According to the Knee society clinical rating system, the knee score was 61.8+/-7.2 preoperatively and 92.8+/-2.8 postoperatively (p<0.05). The function score was 77.8+/-5.8 preoperatively and 89.0+/-6.3 postoperatively(p<0.05). The Insall-Salvati ratio was 1.02+/-0.14 preoperatively and 1.00+/-0.15 at the latest follow up(p=0.018). CONCLUSION: High tibial osteotomy with a long-winged modified Steinmann pin could obtain good correction of angles and clinical results with few complications. And this method was also useful in maintaining the correction angles.
