RESUMEN
Serum creatine kinase [CK] is the gold standard marker for muscle injury. Any muscle damage, if severe enough, can lead to rhabdomyolysis [RM] and subsequent renal failure if not treated properly. This is usually correlated with high levels of creatine kinase. Spine interventions in orthopaedic surgery are associated with surgical "injury" to the back muscles and abnormal levels of creatine kinase. Rhabdomyolysis associated with spine surgery is in fact multifactorial, and most commonly due to prolonged surgery time and certain operative positions, correlated with high risk of developing compartment syndrome [CS]. However, the final complication of acute renal failure is exceptional in these procedures. This paper reviews all reported cases of rhabdomyolysis and acute renal failure following spinal interventions, and discusses the role of creatine kinase in the evaluation of muscle injury as a predictor of rhabdomyolysis and acute renal failure. Most spine surgeries are in fact not correlated with rhabdomyolysis and acute renal failure as this correlates with very high levels of creatine kinase. As a result, monitoring creatine kinase is only advised to follow in certain circumstances, and will only lead to unnecessary expenses
RESUMEN
A variety of cystic lesions are encountered around the knee joint. Particularly, the prepatellar region is the site of soft tissue lesions including mainly bursal fluid collections, joint synovial herniation and tendons ganglia. We report here the case of an exceptional prepatellar posttraumatic epidermal inclusion cyst mistaken for a prepatellar bursitis. With this case report, orthopedic surgeons should widen the array of the differential diagnosis in patients presenting with a post-traumatic prepatellar slow growing soft tissue mass, making epidermoid inclusion cyst a valid possibility to consider
