“…It was a backtracking of the rod with, both times, complete loss of the gained length. To the best of our knowledge, failure of the system with backtracking has been reported twice before in the literature: one case by Ridderbusch et al [27] and six cases by Choi et al [26].…”

“…The random disturbance or rather distribution of the measurements nicely reflects their poor reliability. This finding has significant clinical impact as PJK is a common complication of growing rod treatment and accurate assessment of the PJA is necessary for diagnosis [21,22].…”

“…A relatively modest amount of T1-T12 growth was achieved through lengthening surgeries - a mean of 2 cm over a mean of 6 growing rod lengthening surgeries and 8 VEPTR lengthening surgeries. Other studies have reported 1.65–2.1cm T1-T12 growth using growing rods 15,22 , 1.4–3.4 cm growth using magnetically controlled rods 16,18,19 , and 1.8–3.4 cm T1-T12 growth using rib-based constructs. 17,20,21 On the other hand, substantial increase in spinal length was obtained over the entire course of treatment (Table 2).…”

Study Design Retrospective review of prospectively collected data Objective To compare the use of spine-based vs. rib-based implants for the treatment of early onset scoliosis (EOS) in the setting of rib fusions. Summary of Background Data Treatment for severe early-onset spinal deformity with rib fusions includes growing spine devices with proximal rib or spine anchors. The results of treatment, however, have not been compared between spine-based vs. rib-based proximal anchors. Methods 169 patients with rib fusions treated with rib-based or spine-based constructs and minimum 2-year follow-up were included. 16 patients were treated with proximal spine-based anchors and 153 with proximal rib-based devices (VEPTRs). 104 of the patients with rib-based fixation underwent thoracoplasty at the index surgery. We evaluated change in T1-T12 and T1-S1 height, coronal Cobb angle, kyphosis and number of lengthening/revision surgeries. Results Kyphosis increased a mean of 7 degrees in the rib-based group and decreased a mean of 20 degrees in the spine-based group (p=0.002). Major Cobb angle decreased in both groups (p<0.0001); however, the spine-based group had greater Cobb angle improvement (24 vs. 11 degrees, p=0.04). From implant and lengthening of distraction devices, there was a mean 3.3 cm (22%) increase in T1-T12 height and a mean of 8.0 lengthenings in the rib-based group compared to a 5.7 cm increase and 6.3 lengthening surgeries in the spine-based group. Patients with rib-based constructs had a mean of 11 total procedures, whereas spine-based patients had a mean of 8. Conclusions Patients underwent a mean of 8 lengthening surgeries prior to final fusion or cessation of lengthening with a modest 2.3 cm increase in T1-T12 height. Compared to proximal rib anchors, proximal spine anchors controlled kyphosis and improved Cobb angle correction for early onset scoliosis with rib fusions.
