- Scoliosis is a three-dimensional deformity which is believed to impact lung function, mechanics of respiratory muscles, lung compliance, etc. It is thus of interest to investigated the relationship between degree of scoliosis in terms of apex rotation or Cobb angle respectively and normalized vital capacity (VC). Furthermore it is interesting to study the possibility of estimating lung volumes (and indirectly lung function) using CT volumetric reconstruction.

- Background: The purpose of this study was to report the radiographic results and complications of magnetically controlled growing rod (MCGR) treatment in patients with early-onset scoliosis (EOS).Methods: Patient records and radiographs from a consecutive series of patients treated with MCGR for EOS at two Swedish institutions were reviewed retrospectively. Radiographic analysis included Cobb angle, T1-T12 height, T1-S1 height, thoracic kyphosis, and lung height. Subgroup analyses were performed on primary versus conversion cases and single versus dual rods using one-way analysis of variance (ANOVA) and independent samples t-test.Results: Fifty-two cases treated with MCGR (24 single rods, 28 dual rods) were included from local surgical records into this cohort study, 32 primary and 20 converted from other growth friendly surgical treatment. Mean age at MCGR implantation was 7.4 (2.0-14.6) years old in the primary group and 9.3 (5.0-16.1) years old in the converted group. Mean follow-up time was 3.7 (2.0-7.6) years. Mean (standard deviation; SD) Cobb angle of the major curve changed from 62° (17°) preoperatively to 42° (16°) postoperatively to 46° (18°) at final follow-up (P<0.001). Mean (SD) overall thoracic kyphosis changed from 41° (19°) preoperatively to 32° (14°) postoperatively to 39° (17°) at final follow-up (P=0.018). Mean T1-T12 height was 177 mm (34 mm) preoperatively, 183 mm (35 mm) immediate postoperative and 199 mm (35 mm) at final follow-up (P=0.047). The mean T1-T12 height increased significantly in the primary group but not in the converted group. The number of surgeries was 114 (78 planned, 36 unplanned). The rate of unplanned surgeries did not differ significantly between single and dual rods. The total number of complications was 70 of which 38 were implant related. The overall mean complication rate was 1.4 (0-4). There were no significant differences in complication rates between subgroups.Conclusions: MCGR treatment enabled and maintained correction of spinal deformity while allowing spinal growth. There were no significant differences in complication rates or unplanned surgeries between the groups treated with single or dual rods.

- Background: The optimal treatment of symptomatic perineural (Tarlov) cysts is controversial. Numerous surgical techniques have been proposed with conflicting results. A series of Tarlov cysts treated with a novel surgical approach is presented.Methods: Patients with surgically treated symptomatic perineural cysts during 2013-2016 were included. The main indications for surgery were persistent radicular symptoms, pelvic pain, urinary and/ or bowel disturbances. At surgery, the cyst was opened and fenestrated. The cyst wall was then closed with packing, fibrin glue and a pedicled vascularized fasciocutaneous flap rotated into the area for obliteration of the dead space. Patients were followed-up with clinical visits and repeat magnetic resonance imaging (MRI) scans.Results: Seven consecutive patients were included. The mean age was 50.3 years (range, 25-80 years) and the mean duration of symptoms was 49.3 months (range, 3-130 months). With one exception, all patients had urine and/or bowel problems (incontinence) preoperatively. A lumbar drain was inserted in five patients. The mean follow-up period was 15.4 months. Symptoms improved in 4/7 patients, in two cases no clinical difference was noted while one patient deteriorated. In two cases, a spinal cord stimulator was eventually implanted. In all seven cases, a significantly decreased cyst size was noted on MRI.Conclusions: Cyst fenestration and the use of a vascularized fasciocutaneous flap successfully obliterated all cysts, with satisfactory clinical efficacy. Larger and comparative studies are warranted to clarify the long-term effects of this surgical technique in patients with symptomatic Tarlov cysts.
