Does indirect decompression by oblique lateral interbody fusion produce similar clinical and radiological outcomes to direct decompression by open transforaminal lumbar interbody fusion.

Objectives: Open transforaminal lumbar interbody fusion (O-TLIF) remains the most popular and widely practiced lumbar fusion method even today, providing direct decompression. Oblique lateral interbody fusion (OLIF) is a novel retroperitoneal approach that allows placement of a large interbody cage which provides an indirect neural decompression, and screws can be placed minimal invasively or through the Wiltse OLIF (W-OLIF) approach. We aim to find out the short-term efficacy of W-OLIF to O-TLIF in terms of radiological and clinical outcomes in patients of lumbar degenerative diseases. Materials and Methods: Fifty-two patients were divided equally into two groups (group O-TLIF and group W-OLIF). Several parameters were measured, such as the spinal cord cross-sectional area (SC-CSA), foraminal cross-sectional area (F-CSA), disc height (DH), foraminal height (FH), Schizas grade for stenosis, and Meyerding's grading for olisthesis. Functional scores were measured using the visual analog scale (VAS) for low back pain (LBP) and lower limbs, Oswestry Disability Index. All parameters were repeat measured at 3 months follow-up. Statistical analysis was done using SPSS software. Results: Both groups were similar in composition preoperatively. There was significant improvement in all clinical and radiological parameters post-surgery in either group. However, at 3 months, The DH, FH, FSA, and VAS (LBP) were better in the W-OLIF group than in O-TLIF. Procedure-related complications were seen in both groups (15% in the O-TLIF group and 19% in the W-TLIF group), but only one patient in O-TLIF required revision due to cage migration. Conclusion: Similar improvement occurs in most of the clinical and radiological parameters in the W-OLIF group compared to the O-TLIF group. Few radiological parameters such as the DH, FH, and F-CSA and the VAS (LBP) correction are superior in the W-OLIF group in the short-term follow-up. We conclude that indirect decompression by W-OLIF provides equivalent, if not better, results than the traditional O-TLIF lumbar fusion.

Graphical Abstract in Scientific Research.

A graphical abstract (GA) summarizes the key and important findings of an article graphically, potentially stimulating researchers to view the published manuscript. A GA should enhance dissemination, augment engagement, and impact clinical practice. Infographics play a key role in a quicker understanding of the significant findings of a manuscript. Few level 1 studies reported that GAs enhanced the engagement of readers on social media when compared to plain text abstracts. With the evolution of Industry 4.0, 5.0, and 6.0, GA plays a major role in understanding the technical aspects of various technologies. This article outlines tips to prepare an effective GA and reports the impact of GAs on research and clinical translation.

Is Dysbiotic Gut the Cause of Low Back Pain?

Low back pain (LBP) is the foremost cause of disability that affects the day-to-day activities of millions of people worldwide. The putative trigger of LBP is linked to the gut microbiome (GM) and its dysbiotic environment. With the concept of GM, various disease pathogenesis has been revisited with plausible crosstalks and micromolecular mimicry. In the normal intervertebral disc (IVD), Firmicutes and Actinobacteria were found in abundance. The blood-disc barrier protects IVD from systemic infection, resists inflammation, and halts the immune surveillance of the inner aspects of IVD. The insights into microbial ecology will broaden our horizons in GM and IVD degeneration in LBP cases. However, an improved understanding of GM and back pain has to be explored in large-scale individuals with varied timescales to validate the above findings. The role of GM (diet, prebiotics, probiotics, and fecal microbiota transplantation) in pain modulation can form novel therapies in cases of LBP.

Coinfection of Melioidosis and Tuberculosis Causing Infective Lumbar Spondylodiscitis: A Rare Case Report.

CASE: A 63-year-old farmer who is a known diabetic and chronic alcoholic presented with lower back pain and neurological weakness of lower limbs present for the past 3 months. His acute phase reactants were very high, and magnetic resonance imaging displayed L4-L5 vertebral involvement with epidural, paravertebral, and bilateral psoas abscesses. Cultures of an ultrasound-guided aspiration from the psoas were positive for Burkholderia pseudomallei, and a nucleic acid amplification test also detected Mycobacterium tuberculosis. He underwent posterior decompression and fixation, and intraoperative biopsy confirmed a granulomatous reaction. He received appropriate antibiotics for both diseases. At 1 year, he showed healing on radiographic imaging, with independent ambulation status. CONCLUSION: The coexistence of melioidosis and tuberculosis is rare, and as far as we know, a case of infective spondylodiscitis has not been reported. In patients with infective spondylodiscitis, every attempt should be made to confirm the diagnosis before starting empirical antitubercular treatment (ATT).

Leveraging Artificial Intelligence and Machine Learning in Regenerative Orthopedics: A Paradigm Shift in Patient Care.

The integration of artificial intelligence (AI) and machine learning (ML) into regenerative orthopedics heralds a paradigm shift in clinical methodologies and patient management. This review article scrutinizes AI's role in augmenting diagnostic accuracy, refining predictive models, and customizing patient care in orthopedic medicine. Focusing on innovations such as KeyGene and CellNet, we illustrate AI's adeptness in navigating complex genomic datasets, cellular differentiation, and scaffold biodegradation, which are critical components of tissue engineering. Despite its transformative potential, AI's clinical adoption remains in its infancy, contending with challenges in validation, ethical oversight, and model training for clinical relevance. This review posits AI as a vital complement to human intelligence (HI), advocating for an interdisciplinary approach that merges AI's computational prowess with medical expertise to fulfill precision medicine's promise. By analyzing historical and contemporary developments in AI, from the foundational theories of McCullough and Pitts to sophisticated neural networks, the paper emphasizes the need for a synergistic alliance between AI and HI. This collaboration is imperative for improving surgical outcomes, streamlining therapeutic modalities, and enhancing the quality of patient care. Our article calls for robust interdisciplinary strategies to overcome current obstacles and harness AI's full potential in revolutionizing patient outcomes, thereby significantly contributing to the advancement of regenerative orthopedics and the broader field of scientific research.

Machine learning and deep neural network-based learning in osteoarthritis knee.

Osteoarthritis (OA) of the knee joint is considered the commonest musculoskeletal condition leading to marked disability for patients residing in various regions around the globe. Application of machine learning (ML) in doing research regarding OA has brought about various clinical advances viz, OA being diagnosed at preliminary stages, prediction of chances of development of OA among the population, discovering various phenotypes of OA, calculating the severity in OA structure and also discovering people with slow and fast progression of disease pathology, etc. Various publications are available regarding machine learning methods for the early detection of osteoarthritis. The key features are detected by morphology, molecular architecture, and electrical and mechanical functions. In addition, this particular technique was utilized to assess non-interfering, non-ionizing, and in-vivo techniques using magnetic resonance imaging. ML is being utilized in OA, chiefly with the formulation of large cohorts viz, the OA Initiative, a cohort observational study, the Multi-centre Osteoarthritis Study, an observational, prospective longitudinal study and the Cohort Hip & Cohort Knee, an observational cohort prospective study of both hip and knee OA. Though ML has various contributions and enhancing applications, it remains an imminent field with high potential, also with its limitations. Many more studies are to be carried out to find more about the link between machine learning and knee osteoarthritis, which would help in the improvement of making decisions clinically, and expedite the necessary interventions.

Bilateral Radial Head Fracture Secondary to Weighted Push-Up Exercise: Case Report and Review of Literature of a Rare Injury.

A 33-year-old male presented with bilateral radial head fractures after weighted prone push-up exercise. The patient had Mason type I and II on right and left sides, respectively. He was managed conservatively with limited immobilisation and early range of motion exercises. The fracture healed and patient had no complaints at the last follow-up of 13 months. Bilateral radial head fracture is rare with push-up exercise, and can be successfully treated conservatively with immobilisation and early rehabilitation. Although push-up exercises are an excellent workout with known benefits, unusual modifications of standard techniques should be avoided.

A Shepherd's Crook Deformity of Proximal Femur Treated by Valgus Osteotomy and Bone Grafting.

The Shepherd's crook deformity of the proximal femur is a characteristic radiologic feature of fibrous dysplasia. It may be limited to a single bone, which is called monostotic, or may be polyostotic involving multiple bones as seen in McCune-Albright Syndrome. We report a case of a 19-year-old male patient who presented to us with pain in the right hip for one year. He had dysmorphic facies and multiple café-au-lait spots over the back, which were suggestive of McCune-Albright Syndrome. The radiographs of the hip showed varus deformity of the proximal femur. A lateral closing wedge osteotomy was done and the defect was filled with morselised femoral head allografts and fibular strut allografts. At the 14-month follow-up, the patient remained functionally active without any symptoms. The use of morselised femoral head allograft combined with strut fibular allograft ensures both stability and improved biology at the site of the lesion without any donor site morbidity.

Hoffa's Fracture with Associated Injuries Around the Knee Joint: An Approach to a Rare Injury.

Fractures of the distal femur typically occur in the axial and sagittal planes. A Hoffa fracture is a coronal plane fracture of the femoral condyle, which accounts for 8.7% to 13% of distal femoral fractures. It is usually associated with other injuries around the knee joint and hence is often missed. We conducted a comprehensive systematic review of papers published in the English language using PubMed, Web of Science, Scopus, and the Cochrane Database, which reported Hoffa's fracture associated with other injuries around the knee joint. We selected 11 eligible papers for final analysis and review. These papers had 12 patients with Hoffa's fracture, with associated injuries around the knee joint. The associated injuries with Hoffa's fracture were in the ipsilateral distal femur, proximal tibia fractures, patellar dislocation, patella fracture, and patellar tendon incarceration. The management principles for Hoffa's fracture with associated injuries around the knee joint are: having a high clinical index of suspicion for these injuries, obtaining all trauma series radiographs and computed tomography of the knee, achieving complete articular incongruity, and restoring the functions of the knee joint.
