“…These results are consistent with those described in the literature [4, 5, 8–10] and confirm the efficiency of posteromedial translation maneuvers for the restoration of thoracic kyphosis in hypokyphotic patients. Fletcher et al have demonstrated that all-screw constructs were less efficient than hybrid constructs in the restoration of thoracic kyphosis [12].…”

“…Efficiency of sublaminar bands for the correction of scoliotic deformities in adolescents has been demonstrated by many authors, even in patients with preoperative hypokyphosis [4, 5, 8–10]. In this series, the mean correction rate of the Cobb angle was almost 70%.…”

“…Furthermore, some authors have introduced the fact that the vertebral derotation induced by pedicular screws may be responsible for a decrease of thoracic kyphosis [13, 14]. However, Hirsch et al have shown that sublaminar bands induced a 55% vertebral derotation [8]. Even if derotation occurs with this technique, the main reduction principle is the posteromedial translation, allowing a significant correction in the sagittal plane.…”

Hypokyphosis is currently observed in thoracic idiopathic scoliosis. The use of sublaminar bands allows a good restoration of sagittal balance of the spine. The aim of the study was to provide a middle-term radiographic analysis of patients with adolescent idiopathic scoliosis with preoperative hypokyphosis treated by posterior arthrodesis with sublaminar bands. This retrospective study included 34 patients with Lenke 1 scoliosis associated with hypokyphosis (TK < 20°). A radiographic evaluation was performed with a 2-year follow-up. Cobb angle, cervical lordosis, thoracic kyphosis, lumbar lordosis, and pelvic parameters were measured preoperatively, postoperatively, and at 6-month and 2-year follow-up. The mean preoperative thoracic kyphosis was 10.5° versus 24.1° postoperatively (p < 0.001), representing a mean gain of 13°. Cobb angle ranged from 59.3° to 17.9° postoperatively (mean correction 69%, p < 0.001). Cobb angle increased between the immediate postoperative measurement and the 6-month follow-up (17.9 versus 19.9, p = 0.03). Cervical curvature changed from a 5.6° kyphosis to a 3.5° lordosis (p = 0.001). Concerning lumbar lordosis, preoperative measurement was 39.7° versus 41.3° postoperatively (p = 0.27). At 6-month follow-up, lumbar lordosis significantly increased to 43.6° (p = 0.03). All parameters were stable at final follow-up. Correction performed by sublaminar bands is efficient for both fontal and sagittal planes. Moreover, the restoration of normal thoracic kyphosis is followed by an adaptation of the adjacent curvatures with improved cervical lordosis and lumbar lordosis.

“…Since their introduction (1), the efficacy of SB for the correction of AIS and NMS has been investigated by several authors. Overall, SB can provide good coronal plane correction, comparable to pedicle screw constructs, as well as good correction in the sagittal plane, even in patients with preoperative hypokyphosis; comparable results have been reported for patients with AIS and NMS (Figures 1-3) (1,4,(10)(11)(12).…”

“…Posteromedial translation using SB has been shown to more effectively correct hypokyphosis than pedicle screw constructs while providing equivalent results in the coronal plane. In addition, the restoration of thoracic kyphosis is generally followed by an adaptation of the adjacent curvatures with improved cervical lordosis and lumbar lordosis (11)(12)(13)(14)(15).…”

Recent literature suggests that sublaminar bands (SB) can provide good coronal plane correction, comparable to pedicle screw constructs, as well as good correction in the sagittal plane, even in patients with preoperative hypokyphosis; comparable results have been reported in patients with adolescent idiopathic scoliosis (AIS) and in patients with neuromuscular scoliosis (NMS). Two types of SB constructs can be performed: the band-only construct, indicated for non-ambulatory patients with NMS, and the hybrid construct indicted for ambulatory patients with NMS and for patients with AIS. SB are made of polyester or acrylic material and do provide a safe alternative to sublaminar Luque-type wires (stainless steel) as well as an increased contact area between SB and bone allowing higher corrective forces and reduced laminar fracture risk; the use of SB is not associated with increased risk of neurological injury nor with an increased risk of deep postoperative infection. SB used in a hybrid or in a band-only construct in patients with AIS and NMS, appear to be safe in a trained surgeon hands and can achieve well-balanced spine in both coronal and sagittal planes. This article aimed to provide a review of how SB can restore normal frontal and sagittal spine alignment in patients with AIS and NMS.
