Introduction: Infected non-union is rare in pediatric patients. Various methods have been described in the literature to manage such cases. We present a familiar and simple technique to treat a non-union in pediatric population. Case Presentation: A 4-year-old boy came to us with a right-sided proximal forearm swelling and tenderness. Clinical and radiological features suggestive of osteomyelitis of ulna with a history of the right-sided forearm cellulitis when he was 4 months of age which was managed with incision and drainage at that time. The patient underwent surgery for surgical debridement with drilling of ulnar cortex for pus evacuation. Postoperatively, the patient developed a stress fracture at drilling site which eventually went into a non-union. In second surgery, bony union achieved with the help of non-vascularized fibular strut graft and iliac cancellous graft. Conclusion: There are numerous complications of osteomyelitis in pediatric patients and their management has been previously highlighted throughout literature. Here, we present a rare occurrence case report highlighting management of pediatric atrophic infected gap non-union of ulna by non-vascularized fibula strut stabilized by Titanium Elastic nail which offers a simple yet an elegant solution in a low-cost setting with complete bony union and restoration of function.

In this study, new series of azetidine derivatives were synthesized (4a‐n) from isoniazide (1), Aromatic aldehydes (2a‐n), dihydropyran (3) using SnCl2 catalyst, via one pot multicomponent reaction/cycloaddition reaction. The synthesized azetidine derivatives were characterized by IR, 1H NMR and 13C NMR and have been screened for antimicrobial, antituberculosis and anti‐inflammatory activities. In relation to Staphylococcus aureus (ATCC 25923) promising antibacterial activity was shown, compounds 4e and 4k, followed by compounds 4h, 4n, 4f, 4g and 4l. The synthesized azetidine derivatives, 4a, 4e, 4j and 4m (with zone 12 mm) displayed antituberculosis activity. But its lower potential than, the standard streptomycin (with zone 18 mm). Further 4d compound alone displayed similar activity.

Intro- For TKA, there are two types of bearing designs: xed-bearing and mobile-bearing. Round femoral components articulate with a relatively at tibial articular surface in a xed-bearing knee design. Because the insert does not hinder the natural movements of the femoral component, the mobile-bearing (MB) TKA design is thought to allow more exibility of motion than the xed-bearing (FB) variety. Aim and objective: To compare xed bearing and mobile bearing total knee arthroplasty. Material and methods:This study is a prospective type of study done at Seth GS medical college Mumbai, Department of Orthopaedics during August 2019 to June 2021 on patients undergoing total knee arthroplasty. Patients who were to undergo total knee arthroplasty were invited to take part in the study. This study, done on them was explained in detail to them. An informed consent was obtained. Patients fullling the inclusion criteria were listed. Result: Range of motion achieved after mobile arthroplasty was 123.62±2.94 and in xed arthroplasty it was 121.96±2.74. Pain after last follow up in mobile arthroplasty was 48.83±0.62 and for xed arthroplasty was 47.39±0.86. Flexion gap after last follow up in mobile arthroplasty was 24.13±0.45 and in xed was 24.02±0.45. Stability was almost similar in both mobile and xed arthroplasty. Conclusions: there is no signicant difference between xed arthroplasty and mobile arthroplasty as far as Range of motion, Pain ,Flexion gap. Stability was almost similar in both mobile and xed arthroplasty.

Background: Trauma is one of the leading cause of acetabular fractures, which are becoming more common in developing nations. The treatment of displaced acetabular fractures is a difcult challenge for the orthopedic surgeon. The current study objective was to look at the functional and radiological outcomes of operated acetabular fractures. From 2018 to 2019, we retrospect Methods: ively reviewed the medical records of patients who had operatively treated acetabular fractures at a Tertiary Care Centre and had at least a one-year follow-up. The research was completed by 47 patients in total. The key objectives were functional and radiographic outcomes, as well as complications. The mean age of patients was Results: 40.06±11.84 years with male predominance (82.97%) and road trafc accident was the main reason of fracture (72.34%). The most prevalent acetabulum fracture pattern was left posterior wall (17.02%) and right both column (17.02%). The mean duration before surgery was 8.02±4.84 days. Most common post-operative complication was arthritis seen in 5(10.63%) cases followed by infection 3(6.38%). Radiological outcome was poorly xed in 7(14.90%) patients and well-xed in 40(85.10%) patients at the end of one year. In 53.19% cases Harris Hip Score was excellent followed by good in 29.79% cases. 3(6.38%) patients required secondary surgery. There was signicant association of functional outcome and duration of surgery as per Chi-Square test (p<0.05). Results suggest that operative outcome Conclusion: of acetabular fractures is reliable if judicious operative decision taken at the earliest. Anatomical to fair reduction can give excellent clinical result in these fractures. On follow up, radiological outcomes correlated well with clinical condition of the patient.

Background: The minimally invasive lateral retroperitoneal transpsoas approach is a new method that was designed to minimize problems related with standard or minimally invasive anterior or posterior lumbar spine techniques. The current work used magnetic resonance imaging to determine the anatomic location of the ventral root and retroperitoneal arteries in respect to the vertebral body and to establish the anatomical safe zones. We examined lumbar spine MRI in 50 individuals retrospectively (L1-L2 to L5-S Method: 1 levels). The ventral root and surrounding major arteries were identied using axial T1 and T2 scans. Axial MR scans were utilized to determine the anterior-posterior (AP) diameter of the vertebral endplate, the overlap between the ventral root and the posterior border of the vertebra, and the overlap between the retroperitoneal big vessels and the anterior edge of the vertebra. The safe zone was then determined. From L1–L2 Results: to L5–S1, the mean AP diameter of the vertebral body and the overlap of the vertebral body with the nerve roots and retroperitoneal arteries grew gradually. When we examined the extent of overlap of retroperitoneal arteries with the ventral border of the lower vertebral body endplate, we discovered that the right vascular structures were more posterior than the left vascular structures. The safe working zone was 81.86 percent of the lower endplate of the sagittal diameter of the vertebral body at L1–L2, 70.03 percent at L2–L3, 69.32 percent at L3–L4, 50.08 percent at L4–L5, and 17.92 percent at L5–S1 levels. The Conclusion: retroperitoneal transpsoas method is a less invasive and more efcient alternative to the conventional posterior, open lumbar procedures. It can be used to treat trauma, degenerative disc disease, adult degenerative scoliosis, spondylosis with instability, spondylolisthesis, lumbar stenosis, and neighboring segment failure.
