A Comparison of Maximal Voluntary Ventilation and Forced Vital Capacity in Adolescent Idiopathic Scoliosis Patients
ConclusionMVV and FVC correlated closely with Cobb angle. Twice as many AIS patients could perform an MVV test compared with an FVC test. MVV seems to be a more practical and sensitive PFT than FVC for assessing the pulmonary function of AIS patients in the orthopedic clinic setting.Level of EvidenceLevel II. (Source: Spine Deformity)

The Effect of Expansion Thoracostomy on Spine Growth in Patients with Spinal Deformity and Fused Ribs Treated with Rib-Based Growing Constructs
ConclusionsPatients who underwent expansion thoracostomy at the time of rib expansion device implantation achieved greater improvement in T1–S1 height than those who underwent implantation of rib expansion device alone. Further work is needed to evaluate whether expansion thoracostomy impacts pulmonary function. (Source: Spine Deformity)

Body Image Disturbance Improvement After Operative Correction of Adolescent Idiopathic Scoliosis
ConclusionBIDQ-S is responsive to surgical correction of AIS. The BIDQ-S is a valuable clinical outcome tool to assess the psychosocial effects of scoliosis in adolescents augmenting existing outcome instruments. (Source: Spine Deformity)

Bone Remodeling and Disc Morphology in the Distal Unfused Spine After Spinal Fusion in Adolescent Idiopathic Scoliosis
ConclusionPatients undergoing STF for Lenke 1 AIS are able to achieve normal lumbar lordosis after surgery but seem to regain their sagittal alignment by morphologic changes in the disc more so than the vertebral body. A larger contribution of the vertebral sagittal wedging to the total lumbar lordosis at two years post STF was observed when these variables were compared to the nonscoliotic adolescents.Level of EvidenceLevel IV.

Back Pain and Its Change After Surgery in Adolescents and Young Adults With Idiopathic Scoliosis
ConclusionIn patients undergoing surgery for correction of AIS, back pain is correlated with age. In those with relevant back pain at baseline, surgery is associated with a statistically significant and clinically relevant reduction of pain 24 months later, in skeletally mature young adults and adolescents alike.Level of EvidenceLevel III.

The Risk of Proximal Junctional Kyphosis Decreases in Patients With Optimal Thoracic Kyphosis
ConclusionΔTK was less in the TK group of 30°–39° because the TK of patients who underwent ASD surgery converged to 34.5° just after surgery. Consequently, a lower or higher TK was likely to result in a large ΔTK just after surgery. Therefore, patients who had an optimal TK (30°–39°) had a lower risk of PJK.Level of EvidenceLevel IV.

Spinopelvic Parameters Depending on the Angulation of the Sacral End Plate Are Less Reproducible Than Other Spinopelvic Parameters in Adult Spinal Deformity Patients
ConclusionThese are to our knowledge the first estimates of measurement error for sagittal spinopelvic parameters in ASD patients. Despite near excellent ICCs, we found considerable measurement error for parameters depending on the angulation rather than the location of the sacral end plate.Level of EvidenceLevel II.

The Effects of Preoperative Steroid Therapy on Perioperative Morbidity and Mortality After Adult Spinal Deformity Surgery
ConclusionsPatients on preoperative steroid therapy are at increased risk of 30-day mortality, wound dehiscence, DVT, and blood transfusion after surgery for ASD. An interdisciplinary approach to the perioperative management of steroid regimens is critical.Level of EvidenceLevel III. (Source: Spine Deformity)

Relationship Between Preoperative Plasma Fibrinogen Concentration, Perioperative Bleeding, and Transfusions in Elective Adult Spinal Deformity Correction
ConclusionsIn our cohort undergoing correction of adult spinal deformity, patients with preoperative fibrinogen level lower than 193 mg/dL had significantly higher bleeding than their counterparts. Perioperative transfusion requirements correlated moderately both with the blood loss and preoperative fibrinogen concentration. Incorporation of preoperative fibrinogen allows better prediction of total perioperative blood loss and may therefore guide the treatment team in use of ameliorating therapies.Level of EvidenceLevel IV.

Short-Term Outcomes of Staged Versus Same-Day Surgery for Adult Spinal Deformity Correction
ConclusionsAlthough univariate analysis of our results were in accordance with previously published works, multivariate analysis allowing individual case risk adjustment revealed that LOS was not significantly increased in the staged group as reported in previous studies. There was no difference in infection rates as previously described but an increase in thrombotic events was observed.Level of EvidenceLevel III. (Source: Spine Deformity)

Use of an Accelerated Discharge Pathway in Patients With Severe Cerebral Palsy Undergoing Posterior Spinal Fusion for Neuromuscular Scoliosis
ConclusionsAdoption of a standardized postoperative pathway reduced LOS by 19% in nonambulatory CP patients. Overall, complications, including pulmonary, trended lower in the AD group. Early discharge appears to be possible in this challenging patient population. Although the AD pathway may not be appropriate for all patients, the utility of the AD pathway in optimizing care for more routine PSF for this patient subset appears to be worthwhile.Level of EvidenceLevel III, therapeutic.

Scoliosis in Patients With Friedreich Ataxia: Results of a Consecutive Prospective Series
ConclusionsThe prevalence of scoliosis in FA was high (71%), and thoracic hyperkyphosis, with anterior misalignment, was frequently observed, which might be related to the anterior imbalance frequently encountered in patients with an ataxia. Posterior fusion including sacral instrumentation was only performed in nonambulatory patients, and the loss of ambulation was not associated with spinal surgery.Level of EvidenceLevel IV.

Distraction-Based Surgeries Increase Spine Length for Patients With Nonidiopathic Early-Onset Scoliosis—5-Year Follow-up
ConclusionAt minimum 5-year follow-up, distraction-based surgeries increased spine length for all patients with nonidiopathic EOS; however, neuromusculars had higher preoperative spine length compared with congenital patients and maintained that difference until the 10th lengthening. Although congenital and syndromic patients had similar preoperative spine length, syndromic patients had greater SSL after implantation (L1) and maintained that difference until the 15th lengthening.Level of EvidenceLevel III.

Outcomes of Primary and Conversion Magnetically Controlled Growth Rods Are Different at Two-Year Follow-up: Results of North American Release
ConclusionsPatients with primary MCGR insertion can be expected to have greater radiographic correction and spine length gain than those with conversion from growth-friendly instrumentation to MCGR, most likely because of increased spine stiffness in conversion patients. The rate of complications, primarily implant-related, remains higher in conversion than in primary insertion patients.Level of EvidenceLevel III. (Source: Spine Deformity)
