Operating Light Burn in an Orthopaedic Surgery: A Case Report.

A 40-year-old man with old neglected, non-union, pelvic ring injury right side was surgically treated with open reduction and internal fixation. In the immediate postoperative day, the patient had a large blister adjacent to the surgical site at the right inguinal region which complicated with eschar formation, and later split skin grafting was done. Accidental burns in operation theatre are very unusual.

How is Biodegradable Scaffold Effective in Gap Non-union? Insights from an Experiment.

Objective: To evaluate the role of composite (Chitosan/Chondroitin sulphate/gelatin/nano-bioglass) scaffold in the union of critical size bone defect created in the rabbit's ulna.

Methods: The composite (Chitosan/Chondroitin sulphate/gelatin/nano-bioglass) scaffold was fabricated using the freeze-drying technique under standard laboratory conditions. The scaffold was cut into the appropriate size and transferred into the defect created (critical bone size defect 1 cm) over the right ulna in the rabbit.

Non-subungual presentation of osteochondroma in toes-A case report with review of literature.

A 23-year-old male presented with long-standing swelling in the middle of the third toe right side with difficulty in wearing footwear. Clinical examination revealed it as bony hard fixed swelling moving with interphalangeal joint movements. Clinical diagnosis of benign bony swelling was made and radiological investigation demonstrated features suggestive of osteochondroma.

Design and evaluation of chitosan/chondroitin sulfate/nano-bioglass based composite scaffold for bone tissue engineering.

Chitosan, a natural biopolymer with osteoconductive properties is widely investigated to generate scaffolds for bone tissue engineering applications. However, chitosan based scaffolds lacks in mechanical strength and structural stability in hydrated condition and thereby limits its application for bone tissue regeneration. Thus in the present study, to overcome the limitations associated with chitosan based scaffolds, we fabricated polyelectrolyte complexation mediated composite scaffold of chitosan and chondroitin sulfate incorporated with nano-sized bioglass.
