“…PVCR, as an alternative strategy for vertebral column resection, requires a posterior bilateral approach and has a shorter operation time and reduced blood loss as compared with the traditional vertebral column resection. 13 – 15 Yang et al 6 demonstrated that as the first operative approach, the overall prevalence of PVCR complications was 32%, with the most common being neurological complications (8%). Chen and Dai 4 reported a 40% complication rate with PVCR as a revision strategy, which is similar to the above rate for PVCR as revision surgery (36.7%), but significantly higher than that of PUVCR complications (7.1%).…”

Objective: The objective of this study was to determine the safety and efficacy of posterior unilateral vertebral column resection (PUVCR) as revision surgery for severe thoracolumbar angular kyphosis. Patients and Methods: This is a retrospective cohort study. Adult patients undergoing revision surgery for severe thoracolumbar angular kyphosis in 2010–2016 with ≥2-year follow-up at our institution were assessed. Perioperative complications and clinical outcomes, including blood loss, operation time, Visual Analog Scale score, Oswestry Disability Index, and preoperative and postoperative kyphotic angles, were analyzed. Results: This study included 58 patients who were divided into the PUVCR group and the posterior vertebral column resection (PVCR) group. Age ( P =0.810), sex distribution ( P =0.500), and vertebrae that underwent surgery ( P =0.638) were similar in the 2 groups. Shorter mean operation time was observed in the PUVCR group as compared with the PVCR group ( P <0.001). In addition, less blood loss was recorded in the PUVCR group as compared with the PVCR group ( P =0.001). There were no significant differences between the 2 groups in a change of Visual Analog Scale scores postoperation versus preoperation ( P =0.961), and at postoperative 3 months ( P =0.906), 12 months ( P =0.752), and 24 months ( P =0.811) versus postoperation, respectively. There were no significant differences between the 2 groups in Oswestry Disability Index changes postoperation versus preoperation ( P =0.157), and at postoperative 3 months ( P =0.899), 12 months ( P =0.947), and 24 months ( P =0.811) versus postoperation, respectively. PUVCR and PVCR were comparable in deformity correction ( P =0.434) and final angle correction ( P =0.790). Complication rates in the PUVCR and PVCR groups were 7.1% and 36.7%, respectively. Conclusion: PUVCR has comparable safety and efficacy to PVCR in treating severe thoracolumbar angular kyphosis, with the advantages of the shorter operation time, less blood loss, and fewer complications.

“…They describe an average 38 degrees of correction in the sagittal plane without any neurological injury or pseudoarthrosis during a 2-year follow-up period after BDBO, with a range between 35 and 60 degrees based on type of BDBO performed. [ 2 3 4 ] The technique described in our report can be seen as a modified type I BDBO, where the disk space is not removed. Similar to our claim, Enercan et al .…”

Background:Correction of a focal kyphotic deformity at times requires performing a pedicle subtraction osteotomy, which is accompanied by loss of pedicles as anchor points at the affected level in addition to significant blood loss. To help alleviate these two issues, a novel osteotomy technique for correction of kyphosis using a transforaminal approach to the thoracic vertebral body is described.Methods:We describe a bilateral pedicle-sparing approach and demonstrate it in a patient with proximal junctional kyphosis.Results:The proposed osteotomy resulted in a 28-degree Cobb angle improvement in the sagittal plane.Conclusion:The operation resulted in a similar degree of correction as a pedicle subtraction osteotomy, with the added benefit of maintaining the pedicles closest to the kyphotic deformity.

“…How can a softer material give a stiffer reconstruction? In our experiments, freeze-dried irradiated bone appeared to get impacted faster than the frozen control whatever the particle size (81)(82)(83). During an impaction bone grafting procedure, the stress is applied at such high speed that the flow of liquids may play an important role (84) and the replacement of bone marrow by saline in the processed bone may accelerate the grafts compaction (85).…”

Neck fracture femoral heads for impaction bone graftingEvolution of stiffness and compactness during impaction of osteo-arthrotic and neck-fracture femoral heads

Abstract: Solvent-treated freeze-dried bone from femoral heads procured during arthroplasty for sub-capital hip fractures represents a valuable source of material for allografts, addressing concerns regarding serological testing, medical history and bone quality.
