RT Journal Article SR Electronic T1 Management of femoral shaft infected nonunion through customised Ilizarov external fixator assembly in a morbidly obese patient JF BMJ Case Reports JO BMJ Case Reports FD BMJ Publishing Group Ltd SP e245824 DO 10.1136/bcr-2021-245824 VO 15 IS 1 A1 Muhammad Saad Ilyas A1 Abdul Sattar A1 Uruj Zehra A1 Amer Aziz YR 2022 UL http://casereports.bmj.com/content/15/1/e245824.abstract AB A 19-year-old morbidly obese man presented with infected nonunion of femoral shaft fracture. Patient had history of 13 failed fixation surgeries, assessment revealed 3-centimetre limb-length discrepancy with 3-centimetre gap nonunion. Wound debridement, primary compression and external fixation using a customised Ilizarov external fixation assembly were planned. A four-ring customised assembly was applied. Partial weight bearing was allowed from first postoperative day on walker. Patient was kept on a monthly follow-up. After complete union at 10 months after surgery, frame was dynamised. After 6 months of dynamisation, frame was removed, at that time patient was full weight bearing. Knee was still stiff with a range of motion of 0°–20°, and there was 6 cm of limb length discrepancy, which was managed with a shoe raise. At 9 months after frame removal, patient is mobile with fully united bone. Ilizarov external fixator can be a good managing option in such difficult and complicated cases.
