Upper sacral segment dysplasia refers to a sacral phenotype in which the size and orientation of the upper sacral segment doesn’t allow safe passage of a trans-iliac, trans-sacral screw and characterized by one or more of the following features/criteria:1 Criteria Projection Frequency Acute alar slope (qualitative criteria without cut-off value)…

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…

Pediatric Pelvic Fracture Classifications
Before closure of triradiate cartilage (14 in boys and 12 in girls), pelvic bones are weaker than pelvic ligaments leading to more pubic rami and iliac wing fractures. After closure, they are more likely to sustain fractures of acetabulum, diastasis of pubic symphysis and SI joint separation. Hence, a pediatric…

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…

Refracture of the Patella – Early TBW Failure and Re-fixation
One month following an index TBW procedure (using 4 K‑wires + cerclage), our patient sustained a refracture of the patella after a fall. There was no high-energy direct trauma. This case typifies early failure of a classic TBW construct. Failure Factors Identified in Literature Revision Fixation Alternate Techniques Key Takeaways…
