“…Lavelle and Cheney [17] described 'recurrent fracture' of previously treated vertebrae, although they found no episodes of additional trauma; this term could be easily misunderstood as fracture after trauma. Heo et al [12] reported recollapse of the same vertebrae after PVP.…”

The purpose of this retrospective clinical study was to evaluate the factors that affect recompression of operated vertebrae after percutaneous balloon kyphoplasty (PKP) for osteoporotic vertebral compression fractures (VCFs) and assess their clinical importance. PKP has been used for VCFs with satisfactory results. Several studies about subsequent VCFs adjacent to cemented vertebrae have been reported after PKP. However, the presence and significance of recompression of operated vertebrae have not been adequately described. In total, 80 patients treated with PKP for single thoracolumbar VCFs were reviewed. The follow-up period was at least 1 year. Patients were divided into those without recompression (maintained group, n = 70) and those with recompression (recompressed group, n = 10). Plain roentgenography (preoperative, operative, and last), preoperative BMD, and preoperative MRI were checked. Age, gender, T-score in BMD, duration of symptom, compression rate (CR) of VCF, reduction rate, kyphotic angle (KA), reduction angle, intervertebral cleft (IVC), and non-PMMA-endplate-contact (NPEC) were evaluated. To evaluate the clinical results, we checked the VAS score at each follow-up period. All data were analyzed statistically. The CR for the recompressed group increased significantly after surgery and decreased at the last follow-up (p \ 0.05). The last CR was not significantly different from the preoperative CR. The KA showed the same pattern. The preoperative, postoperative, and last VAS scores were significantly different from one another in both groups (p \ 0.05). Between the groups, preoperative KA, postoperative KA, last KA, IVC, and NPEC were significantly different (p \ 0.05). In particular, last KA, IVC, and NPEC showed highly significant differences (p \ 0.001). In a correlation test for the evaluated factors, IVC (r = 0.557) and NPEC (r = 0.496) were the most significant. The presence of IVC and NPEC may play an important role in inducing recompression of treated vertebrae after PKP. Careful observation of patients with these conditions is necessary to prevent deterioration of their clinical course.

“…Introduction of PMMA-based augmentation initially demonstrated stabilisation and pain relief with persistent height loss and later, with the development of techniques, an advance of reduction ability. Although routinely performed today, these surgeries have shown some limitations [8,11,14,21,22,40] resulting in a continuous development of alternative products [17]. The aim of this study was to show whether an augmentation method with hexagonal metal implants is capable of restoring the stability in an in vitro model of VCF comparable to known methods of treatment (vertebroplasty and PMMA cavity).…”

Vertebroplasty with self-locking hexagonal metal implants shows comparable primary and secondary stiffness to PMMA cement augmentation techniques in a biomechanical vertebral compression fracture model

With the growing incidence of vertebral compression fractures in elderly patients having a fair overall health condition, minimal-invasive treatment techniques are getting in focus of surgical therapy. Cement augmentation is widely performed and its complications and mechanical limitations are well described. Implants avoiding the side effects of cement augmentation while reaching the same level of stability would be desirable. The primary and secondary stability of a new augmentation method with self-locking hexagonal metal implants were investigated and compared with the performance of established augmentation options. 18 fresh-frozen human spinal specimens (Th12-L2/L3-L5) were tested with pure moments of 7.5 Nm in a six-degree-of-freedom spine simulator to investigate primary and secondary stability of three augmentation techniques: (1) vertebroplasty, (2) PMMA filled cavity and (3) hexagonal metal implants. An increasing three-step cyclic loading model was included. Elastic displacement and height loss under loading did not show significant differences between the three test groups. Investigation of primary and secondary stability evenly demonstrated comparable results for all techniques indicating an insufficiency to stabilise the fracture with higher load cycles. The newly introduced method for augmentation with the metal implant Spine Pearls achieved comparable results to bone cement based techniques in a biomechanical in vitro study. Midterm and longterm reduction preservation and ingrowth of the implants have to be proven in further studies.

“…New VCFs after percutaneous vertebroplasty (PVP) or percutaneous kyphoplasty (PKP) include not only newly developed fracture in adjacent vertebrae 7,8,14,19 but also further compression of previously operated vertebrae 6,9,10,12,13 with no additional trauma. Tong and Wu only mentioned new adjacent vertebral fracture.…”
