“…VAS score and PRWE pain score were two common methods to evaluate pain degree and they were used in three trials [20,23,22]. VAS score was used to assess pain and numbness, and PRWE was applied to assess pain and function in patients with distal radius fracture [27,28]. …”

PurposeNowadays, the efficacy of teriparatide in treating osteoporosis was widely accepted, but the discussion about using teriparatide to enhance fracture healing hasn’t come to an agreement. This meta-analysis was conducted to evaluate the effectiveness of teriparatide for fracture healing.MethodsWe searched PubMed, the Cochrane Library, and Embase in August 2016 for randomized controlled trials (RCTs) which concerned the treatment of teriparatide for fracture healing.ResultsFinally, a total of 380 patients were randomly assigned in the 5 trials included in this meta-analysis. There was a significant effectiveness with regards to function improvement in patients following fracture, however, there was no significant effectiveness with regards to time of radiographic fracture healing, fracture healing rate and reduction in pain.ConclusionsThis analysis showed that administration of teriparatide following fracture lacked the effectiveness for fracture healing. Moreover, teriparatide administration had no apparent adverse effects. These results should be interpreted with caution because of some clear limitations. If we want to confirm whether teriparatide improves fracture healing, more high-quality randomized controlled trials are needed.

“…We removed the fixation device with about 12 months after SSPI-f. The inclusion criteria were as follows: Thoracolumbar Injury Classification and Severity (TLICS) score was more than 4; kyphosis was more than 15°; anterior vertebral height was less than 50% [3,8,9]. The exclusion criteria were as follows: Multiple contiguous fractures or non-contiguous fractures; bone mineral density (BMD) of the thoracolumbar spine was at least 2.5 SD below the mean of young normal men; pathological fracture such as tumor, ankylosing spondylitis, inflammatory arthritis; posterior fusion or posterolateral fusion, and laminectomy in the operation; neurological deficit, obsolete thoracolumbar fracture, previous history of spinal surgery.…”

“…In addition, the parameters were collected before implant removal and at last follow-up. The following radiological parameters [6,7,10] were evaluated: Cobb angle (CA) was measured between the inferior endplate (IE) of the lower adjacent vertebra (LAV) and the SE of the upper adjacent vertebra (UAV); vertebral wedge angle (VWA) was the angle between the IE and the SE of fractured vertebra;…”

“…The short-segment pedicle instrumentation with the screw insertion in the fractured vertebra (SSPI-f) usually provides sufficient fixation with good clinical outcomes [3]. However, it is also associated with common complications, such as failure of the instrumentation, the recurrence of kyphosis (KR) and sagittal spinal imbalance [4,5].…”

“…In addition, they failed to discuss the KR after SSPIf, which seemed to be of greater clinical significance than vertebral body re-collapse. Chen et al [7] studied the effect of implant removal on KR after implant removal on KR after SSPI-f, and found that the loss of correction was associated with anterior vertebra height ratio (AVH%) < 50%, anteroposterior ratio and age. However, they did not fully analyze the factors influencing KR before implant removal.…”

KEYWORDSRisk factors; kyphosis reoccurrence; posterior short-segment fixation; thoracolumbar burst fracture. AbstractBackground: The thresholds of risk factors of kyphosis recurrence in thoracolumbar burst fracture patients were still controversial. The aim of this multi-center study was to identify these thresholds. Methods: 169 patients were included in this study. Upper intervertebral angle (UIVA), lower intervertebral angle (LIVA), Cobb angle (CA), anterior vertebral height ratio (AVH%), regional angle (RA), posterior vertebral height ratio (PVH%), vertebral wedge angle (VWA), anteroposterior ratio (A/P%), Clinical assessment included Load Sharing Classification (LSC) score, Thoracolumbar Injury Classification and Severity (TLICS) score, Visual Analogue Scale (VAS), and Body mass index (BMI) were perioperatively evaluated. Patients were divided into KR group and none KR (NKR) group according to whether the loss of CA correction was less than 5˚ or not. The risk factors of KR before or after implant removal were analyzed, respectively. Results: There were significant improvements in postoperative parameters compared with preoperative parameters, such as AVH%, A/P%, VAS, CA, VWA, PVH% (P < 0.001, respectively), and UIVA (P = 0.02). Age (AUC = 0.828) and BMI (AUC = 0.846) were good predictors of KR before implant removal. BMI (AUC = 0.871) was a good predictor of KR after implant removal. Conclusions: There were significant differences in risk factors of KR at different postoperative follow-up stages: age > 49 years, BMI > 24 were risk factors of KR before implant removal; BMI > 25.17 was a risk factor of KR after implant removal.

Risk factors of kyphosis recurrence after implant removal in thoracolumbar burst fractures following posterior short-segment fixation

Abstract: Short-segment pedicle instrumentation including the fractured vertebra was effective in treating thoracolumbar burst fractures. The loss of correction at follow-up after implant removal was associated with age, A/P ratio and anterior vertebral height < 50 %.
