A new method of arthroscopic assisted management of stiff knee: a technical note
Hemant Bansal,Hira Lal Nag,Nishank Mehta,Arnab Sain 대한정형외과 스포츠의학회 2018 Arthroscopy and Orthopedic Sports Medicine Vol.5 No.2
Arthrofibrosis of the knee is a commonly encountered entity and often results from prolonged immobilization or delay in postoperative mobilization of knee. Arthroscopic arthrolysis has replaced open arthrolysis as the gold standard in the management of the stiff knee. Several authors have described their techniques and modifications for arthroscopic management of the stiff knee. Rare but devastating complications have also been reported, particularly when forceful manipulation of the knee is done during surgery. We describe a safe method of arthroscopic-assisted management of a stiff knee with our own modifications to avoid catastrophic complications like iatrogenic fracture, tendon rupture or avulsion while simultaneously achieving improved range of flexion.
Nitric Oxide Metabolite Concentration in Cerebrospinal Fluid: Useful as a Prognostic Marker?
Saurabh Singh,Jyoti Prakash,Rakesh Singh,Ashish Verma,Hemant Bansal 대한척추외과학회 2016 Asian Spine Journal Vol.10 No.5
Study Design: Prospective study. Purpose: To establish the significance of cerebrospinal fluid (CSF) nitric oxide metabolite (NOx) concentration in acute spinal cord injury (SCI) patients to assess the neurological severity and prognosis. Overview of Literature: Quantitative analysis of specific biomarkers in CSF will assess neurological severity more accurately and permit the formulation of a more precise management plan. Methods: Forty SCI patients represented the cases and 20 lower limb injury patients were the controls. NOx concentration in CSF was measured at week 1, 2, and 4 by Griess method. Magnetic resonance imaging (MRI, T2-weighted) done in each case to measure cord edema and neurological severity was assessed using the Frankel classification. Results: CSF NOx concentration peaked at week 2 and declined to normal by week 4. The concentration remained normal in controls. Mean NOx concentration was directly proportional to the severity of acute SCI as correlated with cord edema seen in MRI and neurological severity assessed. Conclusions: CSF NOx concentration can be considered a specific quantitative biomarker in acute stage of SCI to predict the severity and prognosis of SCI patients.
