Thirty patients (25 females, 5 males; mean age 62+/-9 years; range 41-78 years) were prospectively studied. All were diagnosed as having LSS by clinical and radiological evaluations. Pain was assessed by a visual analog scale. The patients were evaluated by the two-staged treadmill exercise tolerance (TET) test, SF-36 health status survey, and Oswestry Disability Index (ODI). The relationships between the TET test, which is an objective functional assessment, and patient-based assessments (SF-36 and ODI), pain and age were investigated. There were significant differences between the functional grades of the patients at the speed of 1.9 km/hour with respect to ODI scores, the physical component scale of SF-36, age, and the preferred speed of the patients (p<0.05). These differences emerged from the fourth functional ...

Because of the several side effects of systemic tranexamic acid, topical usage has been established in several procedures. This study aimed to investigate the effect of local tranexamic acid on vertebral fusion by using macroscopic, radiologic, and microscopic techniques. We also attempted to determine the safe dose range in case some doses had negative effects on fusion. Methods: Twenty-eight Wistar albino rats underwent intertransverse fusion. All rats were randomized into four groups: groups treated with local tranexamic acid doses of 1 mg/kg (D1), 10 mg/kg (D10), and 100 mg/kg (D100) and the control group with no drug (D0). At the end of the eighth week, all rats were sacrificed for evaluation in terms of palpation, mammography, and histopathologic analysis. Results: The manual palpation results presented with lower fusion rates in D10 and D100 groups than in the control group. Radiological examination results were significantly higher in the control group. The histopathologic examination revealed no significant differences between groups in the percent of new bone formation. Conclusion: Our results showed that local administration of tranexamic acid reduced the quality and stability of fusion without a delay in bone formation. However, doses of 1 mg/kg did not reduce the stability in the palpation test. Our findings suggest that 1 mg/kg dose is a critical threshold above which tranexamic acid reduced the bone healing process of fusion and that surgeons should consider the doses of local tranexamic acid during surgery.

Research paper thumbnail of Comparison of Short-Segment Pedicle Instrumentation with Supplemental Hook Fixation under Axial Compression in Relation to Graft Positioning and Posterior Ligamentous Integrity: A Biomechanical Study on the Calf Spine

In addition, it seeks to determine whether the integrity of the posterior ligamentous complex (PLC) affects the stability of the spinal construct. Overview of Literature: Implant and/or bone failure with progressive kyphotic deformity after SSPI is common. To prevent this, several approaches are available, including SHF, anterior strut grafting, use of longer spinal constructs, and extension of the fusion to additional adjacent segments. Methods: A total of eight calf spines were instrumented with SSPI (n=4) and SHF (n=4) with strain gauges on the implants. Strain measurements were performed under axial compression in the following order: intact spine, corpectomy, ventral positioned strut grafting, posterior positioned strut grafting, ventral positioned grafting with resected PLC, and corpectomy with resected PLC. Results: The SHF group showed slightly lower strain values than SSPI in instrumented corpectomy-only specimens, but there were no statistically significant differences between them (p>0.05). The SHF group was significantly more stable than SSPI when strut grafting is employed, regardless of the location of the grafts (p=0.000). In the SSPI group, ventral positioning of the graft contributed significantly to the stability (p=0.000). There was no statistically significant difference between the ventral or posterior positioning of the graft in the SHF group (p=0.187). In addition, the integrity of the PLC did not affect stability in either group (p>0.005). Conclusions: Although not statistically significant, our investigation demonstrated that the most stable method was the SHF along with ventral positioned strut graft. However, if the SSPI is the treatment of choice, ventral positioned strut graft support will be useful in minimizing the risk of implant failure and progressive kyphotic deformity.

Methods: Forty-five patients were evaluated by two physicians and the intra-rater reliability within a subgroup of 21 patients was assessed. Intra-rater and inter-rater reliability were also analyzed using intraclass correlation coefficient (ICC), and Spearman's rank-order correlation test was used to indicate an association between the Manual Ability Classification System (MACS) and the MHCS. Internal consistency was measured using Cronbach's alpha. Results: Intra-rater and inter-rater reliability and internal consistency of the MHCS were found to be excellent with a Cronbach's alpha value of 0.89 and ICC value of 0.97 and 0.98 respectively. A significant correlation was found between the MACS and MHCS (p<0.001, r=-0.805). Conclusion: The inter-rater and intra-rater reliability of Turkish version of the MHCS were found to be high regarding the assessment of Turkish children with CP.

It is unclear whether the use of magnetically controlled growing rods (MCGR) will affect this rate. This study was performed to characterize surgical complications following MCGR in early onset scoliosis. A multicenter retrospective review of MCGR cases was performed. Inclusion criteria were: (1) diagnosis of early onset scoliosis of any etiology; (2) 10 years and younger at time of index surgery; (3) preoperative major curve size &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;gt;30 degrees; (4) preoperative thoracic spine height &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt;22 cm. Complications were categorized as wound related and instrumentation related. Complications were also classified as early (&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt;6 mo from index surgery) versus late (&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;gt;6 mo). Distraction technique and interval of distraction was surgeon preference without standardization across sites. Fifty-four MCGR patients met inclusion criteria. There were 30 primary and 24 conversion procedures. Mean age at initial surgery was 7.3 years (range, 2.4 to 11 y), and mean duration of follow-up 19.4 months. Twenty-one (38.8%) of 54 patients had at least 1 complication. Fifteen (27.8%) had at least 1 revision surgery. Six (11.1%) had broken rods (2 to 4.5 and 4 to 5.5 mm rods); two 5.5 mm rods failed early (4 mo) and 4 late (mean=14.5 mo). Six (11.1%) patients experienced 1 episode of lack or loss of lengthening, of which 4 patients subsequently lengthened. Seven patients (13.0%) had either proximal or distal fixation-related complication at average of 8.4 months. Two patients (3.7%) had infections requiring incision and drainage; 1 early (2 wk) with wound drainage and 1 late (8 mo). The late case required removal of one of the dual rods. This study shows that compared with traditional growing rods, MCGR has a lower infection rate (3.7% vs. 11.1%). MCGR does not appear to prevent common implant-related complications such as rod or foundation failure. The long-term implication remains to be determined. Level IV.

Spinal injuries thus have become a great concern. The unique nature of the pediatric spine should be well-recognized and low back pain in a pediatric athlete should therefore be taken seriously and evaluated thoroughly. In this review article, sports-related lumbar spine problems will be covered including overuse injuries, spondylolysis, pars stress fractures, spondylolysthesis, and lumbar disc herniation. Early identification of these problems will eventually minimize these injuries.

However, if the SSPI is the treatment of choice, ventral positioned strut graft support will be useful in minimizing the risk of implant failure and progressive kyphotic deformity.

Methods: Forty-five patients were evaluated by two physicians and the intra-rater reliability within a subgroup of 21 patients was assessed. Intra-rater and inter-rater reliability were also analyzed using intraclass correlation coefficient (ICC), and Spearman's rank-order correlation test was used to indicate an association between the Manual Ability Classification System (MACS) and the MHCS. Internal consistency was measured using Cronbach's alpha. Results: Intra-rater and inter-rater reliability and internal consistency of the MHCS were found to be excellent with a Cronbach's alpha value of 0.89 and ICC value of 0.97 and 0.98 respectively. A significant correlation was found between the MACS and MHCS (p<0.001, r=-0.805). Conclusion: The inter-rater and intra-rater reliability of Turkish version of the MHCS were found to be high regarding the assessment of Turkish children with CP.

It is unclear whether the use of magnetically controlled growing rods (MCGR) will affect this rate. This study was performed to characterize surgical complications following MCGR in early onset scoliosis. A multicenter retrospective review of MCGR cases was performed. Inclusion criteria were: (1) diagnosis of early onset scoliosis of any etiology; (2) 10 years and younger at time of index surgery; (3) preoperative major curve size &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;gt;30 degrees; (4) preoperative thoracic spine height &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt;22 cm. Complications were categorized as wound related and instrumentation related. Complications were also classified as early (&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt;6 mo from index surgery) versus late (&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;gt;6 mo). Distraction technique and interval of distraction was surgeon preference without standardization across sites. Fifty-four MCGR patients met inclusion criteria. There were 30 primary and 24 conversion procedures. Mean age at initial surgery was 7.3 years (range, 2.4 to 11 y), and mean duration of follow-up 19.4 months. Twenty-one (38.8%) of 54 patients had at least 1 complication. Fifteen (27.8%) had at least 1 revision surgery. Six (11.1%) had broken rods (2 to 4.5 and 4 to 5.5 mm rods); two 5.5 mm rods failed early (4 mo) and 4 late (mean=14.5 mo). Six (11.1%) patients experienced 1 episode of lack or loss of lengthening, of which 4 patients subsequently lengthened. Seven patients (13.0%) had either proximal or distal fixation-related complication at average of 8.4 months. Two patients (3.7%) had infections requiring incision and drainage; 1 early (2 wk) with wound drainage and 1 late (8 mo). The late case required removal of one of the dual rods. This study shows that compared with traditional growing rods, MCGR has a lower infection rate (3.7% vs. 11.1%). MCGR does not appear to prevent common implant-related complications such as rod or foundation failure. The long-term implication remains to be determined. Level IV.

Spinal injuries thus have become a great concern. The unique nature of the pediatric spine should be well-recognized and low back pain in a pediatric athlete should therefore be taken seriously and evaluated thoroughly. In this review article, sports-related lumbar spine problems will be covered including overuse injuries, spondylolysis, pars stress fractures, spondylolysthesis, and lumbar disc herniation. Early identification of these problems will eventually minimize these injuries.
