“…Table 3 [ 7 14 15 16 17 ] summarizes the literature describing the methods of creating a burst fractures in calf spine models. A method described by drop weight alone used a large weight (100 kg), yet produced burst fractures only in 13 of 24 specimens [ 14 ].…”

Study DesignCalf spine model study.PurposeTo describe a technique of creating thoracolumbar burst fractures in calf spine model by low weight drop weight.Overview of LiteratureBurst fractures are one of the commonest types of thoracolumbar fractures and their treatment is controversial. Biomechanical studies aid in the decision of treatment of these fractures. A simple method of creation of burst fractures would help these biomechanical studies.MethodsTen specimens of thoracolumbar spines harvested from 6–8 week old calves were weakened at the target vertebra by standardized osteotomy cuts. Burst fractures were created by dropping a 5-kg of weight from a height of 1.2 m using an in-house device. An accelerometer attached to the weight measured the acceleration at the point of impact.ResultsAverage weight and bone mineral density of the specimens was 390 g and 0.67 g/cm2, respectively. Computed tomography scan analysis of the fractures revealed McCormack grade 2 and grade 3 fractures in 5 and 3 specimens, respectively, Dennis type 2B in 4, type 2A burst fractures in 5 specimens and fracture dislocation in 1 specimen, AO type A3.1.1 in 4 specimens, type A3.2.2 in 4 and type A3.3.3 in 2 specimens. Vertical laminar split fracture was seen in 6 specimens. Average acceleration and energy at impact was 9.04 m/sec and 54.24 Nm, respectively.ConclusionsWe describe a technique to create thoracolumbar burst fractures in calf spine by a drop weight method using a device that is simple to operate and easy to construct. The method is consistent and produces fractures similar to those occurring naturally, and can be considered as an alternative method for creating burst fractures in biomechanical studies.

“…1) at a speed of 40 mm/minute until there was a burst fracture at the weakest part in the middle vertebrae (T12 or L1). 6 Five specimens were fixed with anterior instrumentation alone, using 2 rods connected by 2 screws above and 2 screws below the fractured vertebra plus one tranverse connector. Another 5 specimens were fixed with our modified technique of combined anterior and posterior instrumentation.…”

“…Using longitudinal distraction, Ligamentotaxis is a vital procedure for spinal alignment and canal indirect decompression, causing bone fragments from the posterior wall to be reintroduced into the vertebral body ( 7 , 8 ). Few prospective clinical studies have been conducted to compare the effects of distraction movements on spinal alignment and canal decompression ( 9 - 11 ). On the other hand, research has shown that this method seems to be ineffective ( 12 ).…”

Background There is still no standard of care to manage thoracolumbar burst fractures. With all the recent advances, posterior approaches are still one of the mainstays of treatment. On the other hand, while spinal canal decompression in neurological impaired patients is an important goal of treatment, its technique remains controversial. This study compared the effects of direct laminectomy decompression against ligamentotaxis/indirect canal decompression on neurological and radiographic improvements. Methods A prospective double-blind randomized clinical trial was conducted on 60 thoracolumbar burst-fracture patients meeting our inclusion and exclusion criteria. They were randomized into 2 treatment arms: (1) direct decompression using laminectomy and (2) indirect decompression using ligamentotaxis/distraction. Each patient was observed for 6 months, and their neurological and radiographical data were collected prospectively. Statistical analysis was done by the Student t test, Friedman test, Mann Whitney-U test, Wilcoxon ranked test, and 1-way analysis of variance. Results Among 60 patients enrolled in our study, each treatment arm had an improvement in Frankel scores but there was no difference between the groups at any given time. After 6 months of surgery, local sagittal kyphosis improved in both groups (from 32.2 to 7.43 and 29.93 to 8.77 for the indirect and direct groups, respectively), as well as anterior vertebral height ratio (from 57.73 to 70.7 and 62.17 to 66.27 for the indirect and direct group, respectively) and posterior vertebral height ratio (from 61.17 to 74.87 and 64 to 67.5 for the indirect and direct group, respectively). For between-group comparisons after 6 months, there was a significant difference only for posterior vertebral height ratio ( P = 0.040). Conclusion Posterior approaches with ligamentotaxis have shown to be safe and may present the same outcome as direct decompression techniques using wide laminectomy.
