Sublaminar polyester bands for the correction of idiopathic and neuromuscular scoliosis

Abstract

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.

“…Idiopatinė skoliozė -tai stuburo trimatė deformacija, kuri pasireiškia slankstelių rotacija aplink savo ašį frontalioje plokštumoje ir diagnozuojama, kai didžiausias stuburo deformacijos kampas (Kobbo kampas) yra 10 ir daugiau laipsnių (Negrini et al, 2018, Canavese, Samba, 2020. Visame pasaulyje skoliozė diagnozuojama nuo 0,2 proc.…”

Analysis of Patients Submitted to Surgical Treatment for Neuromuscular Scoliosis With and Without Intraoperative Traction

“…It is defined radiographically as a lateral curvature of the spine greater than or equal to 10º, as measured by the Cobb method, with the presence of vertebral rotation. [1][2][3] Neuromuscular scoliosis (NMS) is characterized by non-congenital deformity in patients with any type of pre-existing neuromuscular condition such as myopathies (Duchenne muscular dystrophy, cerebral palsy, myelomeningocele, spinal muscular atrophy, Friedrich's ataxia, spinal cord injury). It usually progresses rapidly, at an average of 15-20° per year, with the increase in curvature persisting even after growth has ceased.…”

“…In addition to presenting spinal deformity, patients may develop various clinical conditions with concomitant changes in pulmonary and cardiac function. [1][2][3][4][5][6] Surgical treatmentis an important therapeutic option for NMS, since containment of curvature progression by conservative treatment is difficult. Often, surgeries must be performed early, but must always seek a balance between minimizing the appearance and worsening of deformities without limiting the patient's chest expansion and lung volume.…”

“…2 The literature is still inconsistent regarding the best surgical technique to be applied in treatment. 1 The use of intraoperative skeletal traction for the correction of neuromuscular scoliosis has produced significant results. 7,8 Intraoperative halo--femoral or skull-skeletal traction (ISST)has been more of tenreported as facilitating correction in high magnitude scoliotic curves.…”
