Résumé
All limb injuries should be examined with complete documentation of neurovascular assessment as they are often ignored in the busy emergency department setup. This may lead to delay in such diagnosis during the treatment of limb injuries at a follow-up in orthopaedic clinics. Early diagnosis can help orthopaedic team to investigate and start treatment which may help in the recovery of such neurovascular injuries. We report a case of missed neurovascular assessment in the emergency department on a patellar dislocation of a young person leading to foot drop and sensory numbness in the deep peroneal nerve distribution, which improved completely within three and a half months with conservative treatment. This is also the first reported case of foot drop in association with patellar dislocation
