Abstract Background Treatment of congenital hemivertebra is challenging and data on long-term follow-up (≥ 5 years) are lacking. This study evaluated the surgical outcomes of posterior thoracolumbar hemivertebra resection and short-segment fusion with pedicle screw fixation for treatment of congenital scoliosis with over 5-year follow-up. Methods This study evaluated 27 consecutive patients with congenital scoliosis who underwent posterior thoracolumbar hemivertebra resection and short-segment fusion from January 2007 to January 2015. Segmental scoliosis, total main scoliosis, compensatory cranial curve, compensatory caudal curve, trunk shift, shoulder balance, segmental kyphosis, and sagittal balance were measured on radiographs. Radiographic outcomes and all intraoperative and postoperative complications were recorded. Results The segmental main curve was 40.35° preoperatively, 11.94° postoperatively, and 13.24° at final follow-up, with an average correction of 65.9%. The total main curve was 43.39° preoperatively, 14.13° postoperatively, and 16.06° at final follow-up, with an average correction of 60.2%. The caudal and cranial compensatory curves were corrected from 15.78° and 13.21° to 3.57° and 6.83° postoperatively and 4.38° and 7.65° at final follow-up, with an average correction of 69.2% and 30.3%, respectively. The segmental kyphosis was corrected from 34.30° to 15.88° postoperatively and 15.12° at final follow-up, with an average correction of 61.9%. A significant correction (p < 0.001) in segmental scoliosis, total main curve, caudal compensatory curves and segmental kyphosis was observed from preoperative to the final follow-up. The correction in the compensatory cranial curve was significant between preoperative and postoperative and 2-year follow-up (p < 0.001), but a statistically significant difference was not observed between the preoperative and final follow-up (p > 0.001). There were two implant migrations, two postoperative curve progressions, five cases of proximal junctional kyphosis, and four cases of adding-on phenomena. Conclusion Posterior thoracolumbar hemivertebra resection after short-segment fusion with pedicle screw fixation in congenital scoliosis is a safe and effective method for treatment and can achieve rigid fixation and deformity correction.

INTRODUCTION Posterior hemivertebra resection combined with multisegmental or bisegmental fusion has been applied successfully for congenital scoliosis. However, there are several immature bones and their growth can be influenced by long segmental fusion in congenital patients. Posterior hemivertebra resection and monosegmental fusion was therefore suggested for treatment of congenital scoliosis caused by hemivertebra. METHODS Between June 2001 and June 2010, 60 congenital scoliosis patients (aged 2–18 years) who underwent posterior hemivertebra resection and monosegmental fusion were enrolled in our study. A standing anteroposterior x-ray of the whole spine was obtained preoperatively, postoperatively and at the last follow-up appointment to analyse the Cobb angle in the coronal and sagittal planes as well as the trunk shift. RESULTS The mean preoperative coronal plane Cobb angle was 41.6°. This was corrected to 5.1° postoperatively and 5.3° at the last follow-up visit (correction 87.3%). The compensatory cranial curve was improved from 18.1° preoperatively to 7.1° postoperatively and 6.5° at the last follow-up visit while the compensatory caudal curve was improved from 21.5° to 6.1° after surgery and 5.6° at the last follow-up visit. The mean sagittal plane Cobb angle was 23.3° before surgery, 7.3° after surgery and 6.8° at the last follow-up visit (correction 70.1%). The trunk shift of 18.5mm was improved to 15.2mm. CONCLUSIONS Posterior hemivertebra resection and monosegmental fusion seems to be an effective approach for treatment of congenital scoliosis caused by hemivertebra, allowing for excellent correction in both the frontal and sagittal planes.

Abstract Background Previous studies have reported favorable short-term outcomes after posterior-only hemivertebra resection and short fusion in patients with LSHV. However, there is a paucity of data evaluating the long-term outcomes following this procedure. The aim of the study is to evaluate the radiological outcomes following posterior-only hemivertebra resection and short fusion for the treatment of congenital scoliosis (CS) secondary to lumbosacral hemivertebra (LSHV) with a minimum of a 5-year follow-up. Methods A total of 23 patients treated with one-stage posterior-only LSHV resection and short fusion with a minimum of a 5-year follow-up were reviewed. Radiographic parameters including the Cobb angles of the lumbosacral curve and compensatory curve, the upper instrumented vertebra (UIV) tilt, and trunk shift were measured. The complications were recorded accordingly. Results The mean duration of follow-up was 88.6 ± 28.5 months, and the average age at surgery was 7.8 ± 3.5 years. Fusion levels averaged 3.0 ± 0.7 segments. The lumbosacral curve was corrected from 30.7 ± 10.4° to 6.7 ± 7.1° after surgery (P < 0.001), 7.3 ± 6.1° 2 years after surgery, and 8.1 ± 7.0° at the last follow-up. The compensatory curve was spontaneously corrected from 23.7 ± 9.4° before surgery to 8.3 ± 5.2° after surgery (P < 0.001). However, the angle slightly increased to 9.0 ± 4.8° 2 years after surgery and to 9.6 ± 6.4° at the last follow-up. Trunk shift was improved from 27.3 ± 8.6 mm before surgery to 11.7 ± 9.4 mm after surgery, and it decreased to 10.8 ± 8.2 mm 2 years after surgery and 10.4 ± 8.8 mm at the last follow-up. One patient experienced transient neurologic deficits after surgery. One patient was observed to have screw loosening at 1-year follow-up and received revision surgery. Conclusion One-stage posterior-only hemivertebra resection with short fusion is an effective procedure for LSHV, and the correction can be well maintained during longitudinal follow-up. Great attention should be paid to the restoration of lumbosacral horizontalization.

A review was carried out on 59 patients (10 males and 49 females) who had anterior interbody fusion performed with femoral ring allograft packed with autograft bone chips with a minimum follow up of 2 years. The average age at the time of surgery was 49.1 year old (26 to 75). The total number of levels grafted was 141. The diagnosis consisted of multiple degenerative disease in 6, degenerative change below the long segment of fusion for scoliosis in 9, osteoporosis with collapsed fracture in 3, pseudarthrosis after posterior laminectomy and fusion in 35, congenital scoliosis in 3, scoliosis in 2 and paralytic scoliosis due to multiple sclerosis in one. The distribution of levels fused was T12-L1 in 6, L1–2 in 12, L2–3 in 17, L3–4 in 22, L4–5 in 35 and L5-S1 in 39. The remaining 10 levels were in the lower thoracic areas (T7-T12). The operations were performed as anterior fusion alone in 13 patients, one-stage anterior and posterior fusion in 26 patients and two-stage surgery in 20 patients. Anterior instrumentation was used in all 141 levels. At average follow-up (33.7 months) there was no significant change in allograft angles (average = 1.6o). Fusion of the allograft was classified by Bridwell's grading system. At 24 months of the follow up, 97 % of the allografts were in grade I (fully incorporated) and 3% were in grade II (partially incorporated). Compared to 12 months follow-up only 76.2% of the grafts were in grade I, 28 % were in grade II and 0.8% were in grade III. Two patients had deep posterior infections which required further surgery (without resorption of the allograft anteriorly). One patient had a screw migration anteriorly which required removal. Three patients had persistence of radiolucent line at one of the vertebral end plates – graft interfaces but no subsidence of the graft or pain. In conclusion, the femoral ring allograft appeared to benefit the anterior interbody fusion in complex spinal surgery.

OBJECTIVE Institutions investigating value and quality emphasize utilization of two attending surgeons with different areas of technical expertise to treat complex surgical cases and to minimize complications. Here, the authors chronicle the 12-year experience of using a two–attending surgeon, two-specialty model to perform hemivertebra resection in the pediatric population. METHODS Retrospective cohort data from 2008 to 2019 were obtained from the NewYork-Presbyterian Morgan Stanley Children’s Hospital operative database. This database included all consecutive pediatric patients < 21 years old who underwent hemivertebra resection performed with the two–attending surgeon (neurosurgeon and orthopedic surgeon) model. Demographic information was extracted. Intraoperative complications, including durotomy and direct neurological injury, were queried from the clinical records. Intraoperative neuromonitoring data were evaluated. Postoperative complications were queried, and length of follow-up was determined from the clinical records. RESULTS From 2008 to 2019, 22 patients with a median (range) age of 9.1 (2.0–19.3) years underwent hemivertebra resection with the two–attending surgeon, two-specialty model. The median (range) number of levels fused was 2 (0–16). The mean (range) operative time was 5 hours and 14 minutes (2 hours and 59 minutes to 8 hours and 30 minutes), and the median (range) estimated blood loss was 325 (80–2700) ml. Navigation was used in 14% (n = 3) of patients. Neither Gardner-Wells tongs nor halo traction was used in any operation. Neuromonitoring signals significantly decreased or were lost in 14% (n = 3) of patients. At a mean ± SD (range) follow-up of 4.6 ± 3.4 (1.0–11.6) years, 31% (n = 7) of patients had a postoperative complication, including 2 instances of proximal junctional kyphosis, 2 instances of distal junctional kyphosis, 2 wound complications, 1 instance of pseudoarthrosis with hardware failure, and 1 instance of screw pullout. The return to the operating room (OR) rate was 27% (n = 6), which included patients with the abovementioned wound complications, distal junctional kyphosis, pseudoarthrosis, and screw pullout, as well as a patient who required spinal fusion after loss of motor evoked potentials during index surgery. CONCLUSIONS Twenty-two patients underwent hemivertebra resection with a two–attending surgeon, two-specialty model over a 12-year period at a specialized children’s hospital, with a 14% rate of change in neuromonitoring, 32% rate of nonneurological complications, and a 27% rate of unplanned return to the OR.
