Modified Implant Fixation Technique Is an Alternative for Patients with an Anterior Cruciate Ligament Tear in Limited Resource Settings: A Comparison Functional Outcome Study with Polyether Ether Ketone and Bioabsorbable Screws.

Background: Anterior cruciate ligament (ACL) injury is one of the most prevalent factors contributing to knee instability worldwide. This study aimed to evaluate modified metal fixation techniques for ACL reconstruction compared to factory-made implants, such as polyether ether ketone (PEEK) screws, bioabsorbable screws, and modified metal implants. Methods: A retrospective cohort analysis was conducted to assess the functional outcomes of ACL using various fixation methods. Patients who underwent arthroscopic ACL reconstruction at several healthcare facilities were included in the study. The functional outcomes were evaluated using the Lysholm Knee Scoring Scale and the International Knee Documentation Committee (IKDC) score questionnaire at 6- and 12 months post-surgery. Statistical analyses, including the Shapiro-Wilk test and analysis of variance, were performed to compare outcomes among the fixation groups. Results: Thirty-three patients who underwent ACL reconstruction surgery with varying distributions across the three fixation groups (modified metal implants, PEEK screws, and bioabsorbable screws) were included in the study. As measured by the Lysholm and IKDC scores at 6- and 12 months post-surgery, the PEEK group demonstrated the highest average scores. Nevertheless, these functional outcomes were not significantly different between the groups (p = 0.140, 0.770, 0.150, and 0.200). These findings align with those of meta-analyses comparing different fixation methods for ACL reconstruction. Conclusions: While acknowledging the small sample size as a limitation, this study suggests that modified metal implants represent viable options for ACL reconstruction. The selection of fixation methods should consider patient characteristics and preferences, emphasizing biomechanical stability and long-term outcomes. Further research is needed to validate these findings and explore their biomechanical properties and cost-effectiveness.

Vertebral destruction in tuberculous spondylitis correlates with Toll-like Receptor 4 (TLR-4) levels: a cross-sectional study.

Background: Tuberculous (TB) spondylitis is a hazardous infectious disease causing significant spinal deformity. Increased toll-like receptor-4 (TLR-4) activity promotes more extensive infections in patients with TB spondylitis, so it has the potential to be used as a biomarker to predict the severity. This study aims to determine the relationship between TLR-4 levels and the degree of vertebral destruction in TB spondylitis patients. Materials and methods: A cross-sectional study was conducted from May to October 2023. A total of 27 TB spondylitis samples were then measured for TLR-4 serum levels. Vertebral destruction is assessed based on the Spine At Risk Signs (SARS) criteria on X-ray and MRI examinations. Moreover, the degree of sensory and motor impairment was also assessed in this study. The Spearman correlation test assessed the correlation between TLR-4 levels and vertebral destruction. Results: Most of the samples in this study were less than 30 years old (10 people, 37%), female (14 people, 51.9%), had spinal destruction at 1 level (11 people, 40.7%), had paraplegia (8 people, 29.6%), and had hypoesthesia (11 people, 40.7%). TLR-4 levels had a mean value of 8254.1±1076.1 ng/ml. TLR-4 levels were positively correlated with the degree of vertebral destruction (r=0.599, P=0.001), motor disorders (r=0.632.x, P=0.000), and sensory disorders (r=0.574, P=0.002). Conclusion: TLR-4 levels are associated with the severity of vertebral destruction in TB spondylitis, so it has the potential to be used as a prognostic biomarker.

Clinical outcomes and surgical strategy for spine tuberculosis: a systematic review and meta-analysis.

PURPOSE: Spinal tuberculosis (TB) is a slow-developing disease that often causes cord compression, spinal instability, and deformity. Surgery is generally required in cases of refractory disease, severe kyphosis, neurological deficits, or lack of improvement. However, there is a lack of comprehensive evidence in comparing the efficacy of various surgical approaches. The study aims to provide a clearer understanding of the relative effectiveness of the available surgical modalities in the management of spinal TB. METHODS: This review adhered to the PRISMA statement with searching conducted until 11th April 2023. Inclusion criteria included studies involving surgical procedures for spinal tuberculosis, with relevant clinical outcomes reported. Data extraction involved the collection of information on study and population characteristics, interventions used, relevant clinical outcomes, and reported complications. The risk of bias was evaluated using Cochrane's Risk of Bias in Non-randomized Studies tool. RESULTS: Searching resulted in 20 cohort studies that analyzed surgical methods for spinal tuberculosis. Eleven studies had low bias and nine studies had moderate bias. The anterior approach was associated with faster perioperative duration [- 2.02 (- 30.71, 26.67), p < 0.00001], less blood loss [- 4242 (- 176.02, 91.18), p < 0.00001], shorter hospitalization [- 0.19 (- 2.39, 2.01), p < 0.00001], better angle correction [1.01 (- 1.82, 3.85), p < 0.00001], and better correction rates [11.36 (- 7.32, 30.04), p < 0.00001] compared to the posterior approach. Regarding neurological function recovery, the anterior and posterior approaches were equally effective, while the posterior approach was associated with a higher incidence of complications. The review also reported on the complications associated with the surgical approaches, and 9 out of 20 studies reported complications. The anterior approach was found to have fewer complications overall. CONCLUSION: The anterior approach is thought to have fewer complications than both combined and posterior-only approaches, but the variability of the findings indicates that the decision-making process for selecting a surgical approach must consider individual patient and disease characteristics, as well as surgeon training.

Randomized controlled trial of vitamin d supplementation on toll-like receptor-2 (tlr-2) and toll-like receptor-4 (tlr-4) in tuberculosis spondylitis patients.

BACKGROUND: Tuberculosis spondylitis accounts for approximately 50% of all cases of skeletal tuberculosis. Vitamin D plays a role in the immune system. Vitamin D helps in the activation of TLR-2 and TLR-4, which play a role in the process of tuberculosis infection. The objective of this study was to investigate the effect of oral supplementation with vitamin D on TLR-2 and TLR-4 levels in tuberculosis spondylitis patients. METHODS: The true Experiment Design Pretest-Posttest with Control Group (Pretest-Posttest with Control Group) was used for this research. TLR-2 and TLR-4 were measured by ELISA. Repeated ANOVA, ANOVA tests, and Kolmogorov-Smirnov normality tests on the SPSS program were used to statistically analyze the results. RESULT: In the dose groups of 10,000 IU and 5000 IU, significant increases in the levels of vitamin D, TLR-2, and TLR-4 were observed at weeks 4 and 8 (p < 0.05). In the control group, there was no significant increase. CONCLUSIONS: Vitamin D supplements can significantly increase TLR-2 and TLR-4 levels. Supplementation with vitamin D 10,000 IU/day for 8 weeks can increase vitamin D levels > 50 ng/dl to optimally act as an immunomodulator.

Relationship between TLR-2 level and clinical or radiological severity on patients with tuberculosis spondylitis in Dr. Wahidin Sudirohusodo hospital Makassar.

Spinal tuberculosis or TB spondylitis is one of the most common types of extra pulmonary tuberculosis, which is about 15% of all cases. It causes severe morbidity, neurological deficits, and severe deformities in the patients. The growth of Mycobacterium tuberculosis in culture specimens obtained from infected tissue is the single gold standard diagnostic test for spinal TB. Toll-like receptor (TLR) is one of the important receptors in the first-line defence system against microbes. TLR-2 and TLR-4 are known to be associated with tuberculosis infection. Based on this background, the researchers were interested in examining the relationship between TLR-2 levels and the clinical and radiological severity of TB spondylitis patients. A cross-sectional study was conducted with patients diagnosed with tuberculosis spondylitis at Dr Wahidin Sudirohusodo Makassar. Patients diagnosed with TB spondylitis confirmed by blood tests, GeneExpert, and magnetic resonance imaging without prior treatment were included. Data analysis were conducted by using descriptive analysis and one-way ANOVA for bivariate analysis. The mean value of TLR2 levels in TB spondylitis patients was 9.1 g/dL. TLR2 levels in paraesthesia were significantly higher than normal (P < .05). Similar trend were analyzed on the motor neurologic status with TLR2 levels in paraparesis were significantly higher than those in normal (P < .05). There is a significant relationship between the TLR2 levels in TB spondylitis and their impaired motor and sensory function. Spinal destruction has been shown to provide significant relationship with TLR2 value in spondylitis TB.

Functional outcome of campanacci grade 3 giant cell tumours of distal radius after resection and reconstruction with ulnar translocation technique: a case series.

Reconstruction after en-bloc resection can be challenging in cases of Campanacci grade 3 giant cell tumour of the bone (GCTB) of the distal radius. Here, the authors examined the outcomes of patients with Campanacci grade 3 GCTBs of the distal radius who underwent wrist arthrodesis and reconstruction with ulnar translocation. Material and methods: This case series was a retrospective single-centre study. Clinical assessments regarding the functional status and complications were follow-up. The functional results were evaluated using the Musculoskeletal Tumor Society (MSTS) and Disability of Arm, Shoulder, and Hand (DASH) Score. Paired t-tests were used to compare the MSTS and DASH scores separately before and after the operation. Statistical differences were considered significant at P less than 0.05. Results: Seven patients were included in this study. The mean follow-up period was 14.43±8.08 months. The average length of tumour resection was 9.78±2.88 cm. The average range of motion of the involved forearm was 82.66° of supination and 81.54° of pronation. The average MSTS score was 11.71±2.21 before and 25.14±2.41 after the operation (P<0.05). The average DASH score on admission was 40.14±14.66, which decreased to 9.02±4.23 after the operation (P<0.05). Of the seven cases, one case had a recurrence, and one patient had radioulnar synostosis. Conclusion: Wrist arthrodesis combined with ulnar translocation can be considered a simple and effective reconstruction method with preservation of function after en-bloc resection of Campanacci grade 3 GCTB of the distal radius. It provides good functional outcomes with low complication rates.

Tuberculoma of spine mimicking intramedullary tumour: A case report.

INTRODUCTION: Spinal intramedullary tuberculoma (IMTB) is a rare disease that accounts for 1 to 2/100,000 patients with tuberculosis [1]. This case demonstrated that this patient had atypical presentations compared to common tuberculosis considering that IMTB cases are really rare. CASE PRESENTATION: A 19-year-old male presenting with back pain and weakness of both lower limbs, which started in the left lower limb and subsequently involved the right lower limb for three months. He had sensory impairment below T6 and hypoesthesia. He complained of urine hesitancy and a feeling of incomplete voiding of urine. He was on anti-tubercular treatment (ATT) for last two months. MRI exhibited hypointense portion on T1-weighted images. T2-weighted image also showed hypointensity at T6, which suggested for intramedullary mass. Excisional biopsy was suggestive for tuberculoma. DISCUSSION: In TB-endemic country like in Indonesia, tuberculoma should be considered as a differential diagnosis for intramedullary SOL irrespective of age or presence of extra-cranial focus of TB. MRI is the optimal tool for evaluating and diagnosing IMTB at an early stage and useful in follow-up. However, IMTB imaging characteristics may vary with immune response of individual or the stage of the tuberculoma formation [3]. The aim of early surgery is to decompress the spinal cord and achieve improvement in neurological function. CONCLUSION: This case was reported to emphasize that early surgical decompression is required as a delay might cause damage to the spinal cord. This case also provides some evidences based data, thus contributing to the future research studies and clinical practice.

Occipitocervical Fusion and Posterior Fossa Decompression in Neglected Jefferson Fracture-Dislocation of Atlas Associated With Odontoid Peg Fracture: A Case Report.

BACKGROUND: Only a few cases of traumatic atlantoaxial fracture-dislocation have been reported, and neglected cases are seldom found because of the fatal nature of this condition. METHODS: We reported a neglected case of Jefferson fracture-dislocation associated with type II displaced odontoid peg fracture which was nonambulatory and myelopathic. A surgical plan involving posterior fossa decompression and laminectomy of the posterior arch of atlas following posterior spinal instrumentation was then conducted. RESULTS: Patient experienced marked neurologic recovery and was able to stand and walk with assistance during the early postoperative period. CONCLUSIONS: This procedure may be an effective alternative treatment in neglected cases.
