In this report, operative treatment of chronic elbow dislocation using Speed’s technique is described. Reports on this phenomenon are infrequent. This clinically important pathology is quite uncommon but impacts negatively on a patient’s functionality and normal daily activities. We present the case of a 53-year old woman with a missed diagnosis of elbow dislocation. The patient was unable to function because of pain, stiffness and loss of motion. Her diagnosis was missed in the emergency department and in a general practitioner’s office. A correct diagnosis was made three months later. The consultant organized an early date for surgery. The definitive treatment entailed open reduction, VY plasty of triceps and supplementary fixation using K wires through the elbow joint (Speed’s Procedure). The occurrence, patho-mechanics, operative technique and its outcome are discussed.
