“…The device has a "self-locking security system" that allows to significantly reduce the risk of vertebral endplate breakage (6,19). In case of corpectomy and expandable titanium cage implant, the procedure-related complication rate is potentially higher: this approach in fact may involve severe intraoperative bleeding and long surgical times, leading to increased postoperative pain, convalescence, and risk of complications (20)(21)(22)(23)(24). On the contrary, in case of percutaneous MK, there is not intraoperative bleeding and the mean surgical time is critically reduced.…”

“…The cage design may be another reason to explain lower subsidence rate. 22 Recently, rectangular footplate designed cage has been observed to have more subsidence resistance, 23 24 and biomechanical studies have confirmed that peripheral part of endplate could afford more load compression than central. 24 25 Similar to these researches, the rectangular cage applied in the study also rested more on the stronger peripheral area, which could be another reason for a less subsidence rate.…”

Background:Subsidence and late fusion are commonly observed in anterior subtotal corpectomy and reconstruction for treating thoracolumbar burst fractures. The subsidence rate of this surgical method was reported from 19.6% to 75% in the literatures, which would cause treatment failure. Thus, an improvement of anterior surgery technique should be studied to reduce these complications.Materials and Methods:130 patients of thoracolumbar burst fractures treated by minimal corpectomy, decompression and U cage, between January 2009 and December 2010 were included in this study. The hospital Ethical Committee approved the protocols. The American Spinal Injury Association (ASIA) scale, visual analog scales, and Oswestry Disability Index (ODI) scores were used for clinical evaluation. The local kyphosis angle, vertebral height (one level above the fractured vertebral to one level below), canal stenosis, and fusion status were used to assess radiological outcome. All complications and demographic data such as number of male/female patients, average age, mode of trauma, burst level involved, mean surgery time and blood lost were reported.Results:120 patients were followed up for 24 months. Most patients had improvement of at least 1 ASIA grade, and all experienced pain reduction. The mean ODI score steadily decreased after the surgery (P < 0.01). Approximately, 83.3% of patients achieved solid fusion at 3 months and reached 98.3% at 6 months. The kyphosis angle and radiographic height were corrected significantly after the surgery and with a nonsignificant loss of correction at 24 months (P > 0.05). The average canal stenosis index was increased from 39% to 99% after surgery. No cage subsidence or implant failure was observed.Conclusions:The clinical outcomes described here suggest that the selective corpectomy and rectangular cage reconstruction can effectively promote solid fusion and eliminate complications related to subsidence or implant failure.

“…The lack of clear difference between the endcap designs in the presence of supplemental fixation in this study suggests that the primary benefit of the large surface area, wide rectangular endcaps might be in resisting subsidence. In vitro studies investigating static 12 and dynamic 11 subsidence have demonstrated superior behavior with the rectangular endcaps over round endcaps. Further differences between the endcap designs with respect to potential range of motion endcaps afforded by the rectangular stability may be elucidated with cyclic testing.…”

“…10 Larger, rectangular endcaps have been shown to increase resistance to subsidence by traversing the width of the vertebral body to rest on the apophyseal ring ( Figure 1). 11,12 The apophyseal ring has been shown to possess the strongest and most dense vertebral body endplate bone. 13 In addition to reducing the likelihood of subsidence, rectangular endcaps for an interbody expandable device have been proposed to provide a more stable construct for anterior column support.…”

Contribution of Round vs. Rectangular Expandable Cage Endcaps to Spinal Stability in a Cadaveric Corpectomy Model

et al. 2015

BackgroundExpandable cages are gaining popularity in anterior reconstruction of the thoracolumbar spine following corpectomy as they can provide adjustable distraction and deformity correction. Rectangular, rather than circular, endcaps provide increased resistance to subsidence by spanning the apophyseal ring; however their impact on construct stability is not known. The objective of this study was to investigate the contribution of expandable corpectomy cage endcap shape (round vs. rectangular) and fixation method (anterior plate vs. posterior pedicle screws) to the stability of an L1 sub-total corpectomy construct.
