Perilunate Dislocation

Introduction Perilunate dislocation (PLD) and perilunate fracture dislocations are complex types of wrist instabilities, resulting from high energy injuries such as motor vehicle accidents, falls from height, and extreme athletic activities that constitute about 10% of all carpal injuries (1), while scaphoid fractures, associated with dislocation of capitate from the lunate, referred to as transscaphoid perilunate dislocations (TSPDs) are observed in 61% to 65% of these types of injuries (2). Perilunate injuries can result in poor functional results, if left untreated, and patients may have mild to moderate dysfunction even after treatment (3). Although closed treatment was historically advocated for these injuries, early treatment with open …show more content…

The arm was prepped and draped on the hand table with the patient in supine position; pneumatic brachial tourniquet was fastened. A volar approach was used with internal fixation of scaphoid fracture with Herbert screw. The incision was centered over the scaphoid’s tubercle and curved distally in to the base of thenar eminence, the flexor carpi radialis was exposed and retracted ulnarly, the radial artery was protected, the dorsal sheath of flexor carpi radialis was incised longitudinally, and pericapsular fat was divided; the anterior capsule of wrist was incised longitudinally to display the anterior surface of scaphoid. Fibrin and clots were removed from the fracture surface and after exposing the distal fragment of the scaphoid and the capitate head by traction on the hand, the proximal fragment was pushed dorsally and distal fragment pulled volarly. The fracture was then reduced and the scaphoid fracture was fixed with a screw (Herbert: Zimmer, Inc). Three k-wires were inserted from radial side of the wrist, distal to the radial styloid; two were used to stabilize the scaphoid to the lunate and the other to secure the scaphoid distal to the capitate. There were no ligamentous repair or reconstruction required. Then the wires were placed inside out, remaining one end of each wire percutaneous. Anterior part of the wire was carefully repaired and the skin was closed as routine. Then the wrist was immobilized with long arm cast for about eight weeks. The k-wires and splint were removed after eight weeks, then, physiotherapy of wrist with gentle movements started, and heavy manual activities were avoided for at least three
