Bilateral trans scaphoid perilunate fracture dislocation

bilateral trans scaphoid perilunate fracture dislocation Trans-scaphoid perilunate fracture-dislocations often accompany a comminuted fracture of the scaphoid and disruptions of the intercarpal ligaments, and bone union and ligament healing time is delayed  a unique case of bilateral trans-scaphoid perilunate dislocation with dislocation of lunate into the forearm.

Background: floating forearm injuries, perilunate injuries, with an elbow dislocation, are rare and challenging to treat methods: we present the case of an unusual variant of a floating forearm injury, trans-scaphoid perilunate fracture dislocation and elbow dislocation, with a concomitant open. If scaphoid remains attached to the radius a fracture may occur throught the scaphoid waist (trans-scaphoid perlilunar dislocation) untreated leads to progressive arthritis, pain, dysfunction lunate=keystone of carpus. Typical appearances of a trans-scaphoid perilunate dislocation fracture of the scaphoid with dorsal dislocation of the carpus relative to the lunate 4 case question available lateral capitate (c, blue) is dislocated dorsal to the lunate (l, yellow) the proximal pole of the scaphoid (pp) has remained aligned with the lunate, whereas. Perilunate fracture–dislocations are high-energy injuries, produced by wrist hyperextension 3,15 there is disruption of the palmar capsuloligamentous complex, starting radially and propagating through the carpus in an ulnar direction 3,15 this dislocation takes a transosseous route through the scaphoid resulting in a trans-scaphoid.

X-rays and ct scan were done which showed a trans-scaphoid perilunate dislocation (fig 3a and 3b) 3a 3b fig 3 (a) and (b)- preoperative radiographs of the patient showing trans-scaphoid perilunate dislocation. Transscaphoid perilunate fracture dislocation is a rare injury and can be easily missed at the initial treatment once ignored, late reduction is not possible and needs extensive dissection an alternative treatment such as proximal row carpectomy may be required for neglected injuries, but surgical. Perilunate dislocations are often associated with fractures of the scaphoid and radial styloid and less commonly with the capitate, triquetrum, and ulna styloid wrist radiographs with evidence of these fractures should be scrutinised carefully.

This combination of injuries is known as ‘trans-scaphoid perilunate dislocation’ when no fracture is present, perilunate and lunate dislocations can be very subtle radiographically – unfortunately, these injuries are frequently missed initially and the diagnosis may be significantly delayed as a result. Trans-scaphoid perilunate fracture dislocation is a complex carpal dislocation causing marked disruption of the carpal structures open treatment has been accepted as standard for this injury. A trans-scaphoid perilunate fracture dislocation pre-reduction, he had median nerve symptoms and capitate on the lateral radiograph 3 ‘crowding’ of the carpal bones on the pa radiograph 4 ‘piece of pie’ sign on the pa radiograph trans-scaphoid perilunate fracture dislocation: ‘notjust a scaphoid fracture’. Perilunate fracture–dislocations are high-energy injuries, produced by wrist hyperextension3, 15 there is disruption of the palmar capsuloligamentous complex, starting radially and propagating through the carpus in an ulnar direction3, 15 this dislocation takes a transosseous route through the scaphoid resulting in a trans-scaphoid. Volar perilunate trans-scaphoid dislocations of the wrist are rare approximately 16 cases have been described in the literature,1 with none of the reports describing this injury in a skeletally.

60% of perilunate dislocations associated with ascaphoid fracture which is then termed a trans-scaphoid perilunate dislocation x-rays ap view triangular orientation of the lunate look for associated scaphoid fracture the lateral view will help differentiate perilunate from lunate dislocations. Ap and lateral radiographs of the wrist are shown in figures a and b respectively what is the most appropriate next step in management chronic trans-scaphoid perilunate fracture dislocation (c2330) hand - lunate dislocation (perilunate dissociation) - lunate dislocation (perilunate dissociation) hpi - patient fell with the bike. There were eight trans-scaphoid fracture–dislocations and four radial trans-styloid fracture–dislocation in the fracture–dislocation group the final wrist range of motion, grip strength, and radiologic indexes were compared between the perilunate dislocation and the fracture–dislocations groups. Of all the wrist dislocations ,the perilunate dislocation is most common and the most common pattern is trans-scaphoid parilunate fracture dislocation most patients are young males and mode of injury is hyperextension injury to the wrist following a motor vehicle accident, contact sports or fall from height. 3 perilunate and lunate dislocations range of ligamentous injuries high impact young men associated with scaphoid fractures uncommon injuries, 10% of all carpal injuries long term complications can be difficult to diagnose.

Scaphoid fracture in the elite athlete fractureofthescaphoid,themostcommonlyfrac-tured carpal bone, presents a dilemma for the computed tomography is used to evaluate scaphoid fractures at the start and end of care from a trans-scaphoid perilunate dislocation. Acute volar lunate dislocation dorsal trans-scaphoid perilunate dislocation et al dislocations of the lunate with and without fracture of the scaphoid j bone joint surg 1984 66b:391. However, transradial styloid perilunate dislocation is a very rare type of injury majeed et al, reported a 1-year follow-up in a case with trans-styloid, trans-scaphoid, and trans-triquetral perilunate fracture-dislocation treated by open surgery ( 6 . Trans-scaphoid perilunate fracture dislocations are the most commonly described perilunate fracture dislocations our case report describes an unusual trans-scaphoid perilunate fracture dislocation with complete disruption of both the sl ligament and scaphoid. Perilunate dislocation and perilunate fracture-dislocation abstract perilunate dislocations and perilunate fracture-dislocations usually result from high-energy traumatic injuries to the wrist and are.

bilateral trans scaphoid perilunate fracture dislocation Trans-scaphoid perilunate fracture-dislocations often accompany a comminuted fracture of the scaphoid and disruptions of the intercarpal ligaments, and bone union and ligament healing time is delayed  a unique case of bilateral trans-scaphoid perilunate dislocation with dislocation of lunate into the forearm.

Trans-scaphoid perilunate fractures-dislocations are rare lesions they occur in a high-energy trauma the concomitent lesion of both wrists is exceptional we report a case of bilateral trans-scaphoid perilunate dislocated wrist fracture in a 21-year-old man the dislocation was treated by opened. Trans-scaphoid transcapitate (tstc) perilunate fracture-dislocation (plfd) is a rare type of perilunate injury because of the rarity and complexity of this entity, initial diagnosis may be delayed and the extent of osseous and ligamentous lesions underestimated. Like other dislocations, the perilunate dislocation is an emergency and should be reduced as soon as possible this may be performed in the emergency department (ed), with delay of the definitive procedure, as any fracture associated with perilunate dislocations typically requires stabilization with small compression screws or percutaneous pins.

  • Perilunate dislocations, perilunate fracture-dislocations (plfds), and lunate dislocations are high-energy wrist injuries that can and should be recognized on radio-graphs these injuries are a result of important sequential osseous and ligamentous injuries or failures.
  • Taken x-ray disclosed trans-scaphoid dorsal perilunate fracture dislocation and avulsion fracture of ulnar styloid excessive displacement of the lunate to middle third of the forearm and proximal scaphoid with multiple bony fragments to distal third was obvious ( figure 1a & 1b .

Of perilunate dislocations, greater arc injuries are more common, with approximately two thirds of perilunate dislocations classified as greater arc injuries 1, 3 the trans-scaphoid perilunate dislocation is the most common variant of this type of injury encountered in all published series of greater arc perilunate fracture-dislocations, 95%. Trans-scaphoid perilunate fracture-dislocation respectively, while 71 and 7111 in non-surgically treated group respectively wrist range of motion was also more favorable in operative group (55 degrees flexion - 54 degrees extension for trans. The injuries included 2 dorsal trans-radial perilunate dislocations, 4 trans-radial styloid perilunate disloca- tions, and one combined dorsal and styloid trans-radial dislocations open reduction, internal fixation with k wires.
