Abstract
BACKGROUND Razorback deformity with stiff thoracic scoliosis creates a complex three-dimensional deformity. Posterior spinal fusion (PSF) and thoracoplasty can correct rib hump deformity and improve patient satisfaction. However, conventional thoracoplasty may impair pulmonary function and increase complications. We present a modified thoracoplasty (MTP) technique for addressing rib hump deformity in stiff thoracic scoliosis patients, emphasizing its clinical efficacy and safety. METHODS This study included 44 patients with stiff thoracic scoliosis and razorback deformity who underwent surgery between January 2010 and May 2021. Patients were divided into PSF + MTP (n = 27) and PSF (n = 17) groups. Surgical parameters, complications, radiographic improvements, pulmonary function, and Scoliosis Research Society-22 scores were evaluated preoperatively and at 3 months and 2 years postoperatively. RESULTS There were no significant differences in baseline characteristics between the 2 groups, except for the rib hump height, which was higher in the PSF + MTP group. The PSF + MTP group showed superior correction of the thoracic curve and rib hump height compared to the PSF group, with significant improvements in self-image scores. No significant differences were observed in pulmonary function between the groups. The operative time was longer in the PSF + MTP group, but there were no significant differences in intraoperative blood loss, hospitalization costs, or major complications. Regression analysis indicated that the type of surgery, thoracic Cobb angle, and preoperative self-image scores were significant predictors of postoperative self-image scores. CONCLUSIONS MTP provides enhanced correction of thoracic curve and rib hump deformity without significantly increasing pulmonary function impairment or complication rates. It also improves patients' self-image, making it a valuable addition to PSF in treating stiff thoracic scoliosis with rib hump deformity.

Ponte Osteotomies in the Surgical Treatment of Adolescent Idiopathic Scoliosis: A Systematic Review of the Literature and Meta-Analysis of Comparative Studies. CHILDREN (BASEL, SWITZERLAND) 2024; 11:92. [PMID: 38255405 PMCID: PMC10814379 DOI: 10.3390/children11010092] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/21/2023] [Revised: 01/09/2024] [Accepted: 01/10/2024] [Indexed: 01/24/2024]
Abstract
The purpose of the present paper is to assess if Ponte osteotomies (POs) allow for a better correction in adolescent idiopathic scoliosis (AIS) surgery and to investigate their safety profile. A systematic search of electronic databases was conducted. Inclusion criteria: comparative studies that reported the outcomes of AIS patients who underwent surgical correction through posterior-only approach with and without POs. Clinical and radiographic outcomes were extracted and summarized. Meta-analyses were performed to estimate the differences between patients treated with and without POs. p < 0.05 was considered significant. In total, 9 studies were included. No significant difference in thoracic kyphosis (TK) change between patients treated with and without POs was found (+3.8°; p = 0.06). Considering only hypokyphotic patients, a significant difference in TK change resulted in POs patients (+6.6°; p < 0.01), while a non-significant TK change resulted in normokyphotic patients (+0.2°; p = 0.96). No significant difference in coronal correction (2.5°; p = 0.10) was recorded. Significant estimated blood loss (EBL) (142.5 mL; p = 0.04) and surgical time (21.5 min; p = 0.04) differences were found with POs. Regarding complications rate, the meta-analysis showed a non-significant log odds ratio of 1.1 (p = 0.08) with POs. In conclusion, POs allow for the restoration of TK in hypokyphotic AIS, without a significantly greater TK change in normokyphotic patients, nor a significantly better coronal correction. Considering the significantly greater EBL and the trend toward a higher complications rate, the correct indication for POs is crucial.

Posterior Spinal Fusion Surgery for Neuromuscular Disease Patients with Severe Scoliosis Whose Cobb Angle Was over 100 Degrees. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:1090. [PMID: 37374294 DOI: 10.3390/medicina59061090] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/30/2023] [Revised: 05/26/2023] [Accepted: 06/02/2023] [Indexed: 06/29/2023]
Abstract
Background and objectives: Patients with neuromuscular diseases usually have progressive neuromuscular scoliosis (NMS), requiring invasive surgery. Some patients present with severe scoliosis at the time of consultation and are difficult to treat. Posterior spinal fusion (PSF) surgery combined with anterior release and pre- or intraoperative traction would be effective for severe spinal deformities but would be invasive. This study aimed to evaluate the outcomes of PSF-only surgery for patients with severe NMS with a Cobb angle > 100°. Materials and Methods: Thirty NMS patients (13 boys and 17 girls; mean age 13.8 years) who underwent PSF-only surgery for scoliosis with a Cobb angle > 100° were included. We reviewed the lower instrumented vertebra (LIV), duration of surgery, blood loss, perioperative complications, preoperative clinical findings, and radiographic findings, including Cobb angle and pelvic obliquity (PO) in the sitting position pre- and postoperatively. The correction rate and correction loss of the Cobb angle and PO were also calculated. Results: The mean duration of surgery was 338 min, intraoperative blood loss was 1440 mL, preoperative %VC was 34.1%, FEV1.0 (%) was 91.5%, and EF was 66.1%. There were eight cases of perioperative complications. The Cobb angle and PO correction rates were 48.5% and 42.0%, respectively. We divided the patients into two groups: the L5 group, in which the LIV was L5, and the pelvis group, in which the LIV was the pelvis. The duration of surgery and PO correction rate in the pelvis group were significantly higher than those in the L5 group. Conclusions: Patients with severe NMS demonstrated severe preoperative restrictive ventilatory impairments. PSF surgery without anterior release or any intra-/preoperative traction showed satisfactory outcomes, including acceptable scoliosis correction and improved clinical findings, even in patients with extremely severe NMS. Instrumentation and fusion to the pelvis for severe scoliosis in patients with NMS showed good PO correction and low correction loss of Cobb angle and PO, but a longer duration of surgery.
