Traumatic avulsion of the right diaphragm from the lumbocostal arch is
a very rare lesion. The authours report the case of a 27-year-old man
who had suffered a severe polytrauma with blunt thoracic injury, frac
ture of the lumbar spine, Malgaigne-type fracture of the pelvis and fr
acture of the femoral shaft on the right side, 10 years before. At the
time of injury the lesion of the diaphragm went unnoticed. The diagno
sis was made 10 years later when the patient was referred for chronic
right thoracic pain combined with postprandial abdominal distension an
d crampy pain in the abdomen. The chest radiogram and CT-scan showed d
isplacement of the right kidney and most of the right colon into the t
horax due to avulsion of the diaphragm from its dorsal insertion on th
e lumbocostal arch. Surgical repair was necessary to obtain relief fro
m pain and to prevent intestinal obstruction. Reduction of the hernia,
reinsertion of the diaphragm to the lumbocostal arch and reinforcemen
t of the repair with a prolene mesh prosthesis was performed through a
right thoracophrenolumbotomy incision.
