Key concept Irrigation and debridement with polyethylene insert exchange (IDPE) or Open debridement and polyethylene insert exchange (ODPE) is a form of DAIR (Debridement, Antibiotics and Implant Retention) used for selected acute periprosthetic joint infections (PJI) after TKA. When to consider and when not to consider IDPE or ODPE? Favorable…

Crescent Fractures (Trans-iliac Fracture Dislocation of Sacroiliac Joint)
Definition: Transiliac fracture dislocation of the SI joint, which combines a ligamentous disruption of the inferior part of the SI joint with a vertical fracture line of the posterior ilium, extending from the SI joint and reaching the iliac crest at different levels. The posterior superior iliac spine (PSIS) remains…

Simultaneous Bilateral Total Knee Arthroplasty (SBTKA): A Practical Perspective
Recently, we operated on a 58-year-old female patient with advanced bilateral knee osteoarthritis (OA). She underwent simultaneous bilateral total knee arthroplasty (TKA) using a medial parapatellar approach. Both femoral components were size 3, tibial components size 3, and a 10mm polyethylene insert was used on each side. Some practical considerations…

Retrograde Percutaneous Screw Fixation of Posterior Column Acetabulum Fracture : C-Arm Views & Technique
Today in the OR, I observed a retrograde percutaneous screw fixation of a left posterior column acetabular fracture in a 63-year-old male. While I wasn’t scrubbed in, it offered a fantastic opportunity to understand the precision and fluoroscopic guidance required for this minimally invasive approach. It is often said that, “Percutaneous fixation is a surgery performed…

Drill Bit Breakage During Proximal Interlocking Screw Insertion in IMIL Nailing – A Practical Lesson from the OR
In orthopedic trauma surgery, complications often come unexpectedly which must be dealt critically. even routine procedures can throw a surprise. We came across one such unexpected complication while operating on a case of 23-year-old male with bilateral closed shaft of femur fracture with antegrade intramedullary interlocking (IMIL) nail on left…
