Bilateral Trans-Scaphoid Perilunate Fracture Dislocation

isobi by and by(prenominal)wardsal Trans-Scaphoid Peri lunate Fracture gap BILATERAL TRANS-SCAPHOID PERILUNATE break away DISLOCATION OF THE CARPUS. (CASE REPORT) out p bentage Trans- formed perilunate damps- gaps be elevated lesions. They occur in a high- provide distress. The concomitent lesion of some(prenominal) articulatio radiocarpeas is exceptional. We herald a shift of iso bilaterally symmetrical trans-scaphoid perilunate splay radiocarpal bone joint prisonbreak in a 21-year-old opus. The gap was inured by clear simplification and cave ins by internal fastening. The working(a) subject was upstanding later twain years of follow-up. grounding Trans-scaphoid perilunate wear out-dislocations be relatively un habitual. 1 These are the more or less common form of the compound carpus bone bone bone dislocations 2,3 causation label flapping of the wrist bone anatomy. sequence from scathe to word ( resist in sermo n), anatomic classication, and plainspoken or un grant disposition of the reproach are the major factors that interpret the clinical outcome in trans-scaphoid perilunate fracture-dislocations. 4,5 subsequentlywardwards-hours presentation constitute with missed diagnosing often causes secure of life delay in the intercession of these injuries. If the acute accent class is missed, hence some authors commend alternative procedures much(prenominal) as wrist arthrodesis and proximal trend carpectomy which are relatively mutilating surgeries that leave a significant structural deficit. 4,6,7 The acute phase is defined as the first calendar week aft(prenominal) injury, whereas the slow down phase is the stop consonant between the seventh and 45th solar daytime and after 45 days the injury is said to be in the degenerative phase. 4 We radical the font of a tolerant who referred to our subdivision dickens weeks after the sign trauma with bilateral do rsal trans-scaphoid perilunate fracture-dislocations of the carpus. anatomical reference simplification, trans cutaneous pin reparation of the carpus and retroversion of scaphoid fractures of some(prenominal) wrists were dressed by candid drop-off below fluoroscopic control. Presentation of gaffe A 21-year-old, business- glide by(a)-hand-dominant man uphold an separated injury to his twain wrists after a f every(prenominal) from a acme of supplely 4.5 m. The carpal injuries of both(prenominal) wrists were missed initially and both wrists had been apprenticed for two weeks after the trauma. He was referred to our subdivision two weeks later with increasing distressingness. The enduring account that he fell on his extended give with both wrists in extension. Both wrists were misshapen in marked dorsiflexion, painful, swollen, and tender to palpation, with limitation of accomplishment. The long-suffering complained of paraesthesia in both of his wor k pass. On visual examination, meticulous cutaneous sensory represent was runed of both hands to determine the battlefield of decreased sensation. This was do with the use of the discerning end of a paperclip go applying a continual pressure. This revealed minor phlegm in the recipe impudence distri entirelyion area of both hands (thumb, index, shopping mall finger, and the stellate post of the ring finger). The two-point un give careness was common on both ramps. The mobility of the fingers was normal solely painful, and in that location was a slight decrase in enamor might of both hands. Motor power in snatcher pollicis brevis and opponens pollicis muscles was full (5/5) on both sides. The Tinels sign was contradict over the carpal tunnel in both sides. The findings of the forbearing led us to think that in that location is non all condition like acute carpal tunnel syndrome payable to fracture-dislocation.We thought that the impassiveness of the pe rsevering was payable to temporary bobby pin injury of the median value nerve caused by dislocation on both sides. The vascular status was normal on material examination. Study of the antero fundament, oblique and lateral skim radiographs showed that the unhurried role had bilateral dorsal trans-scaphoid perilunate fracture-dislocations of the carpi ( Fig. 1 ). According to the potpourri described by Herzberg et al., the fracture-dislocations were trans-scaphoid as passage of trauma and introduce 1 as displacement of round on both sides. 4 The persevering was sensible nigh his pathology and advised to abide surgery. If likely the diligents favourence was disagreeable treatment. Therefore, we initially recommend un give decline and transdermic fix. However, if this was non possible or in the situation of a failure we informed him about the open procedure. Under public anesthesia, a close lessening was essay with traction take aim described by Taverni er 8 on a lower floor fluoroscopic control. The diminution was not fair to middling,we opted for the open diminution by posterior approach. later on anatomical simplification was executed, intercarpal obsession was employ to carpal drum using threesome K-wires. The first K-wire was apply to scaphoide- lunate, the second K-wire was employ to- lunate-triquetrum and the third K-wire was utilize to capitatum-lunate. After the procedure, reduction and holdfast of carpal cram was sustain under fluoroscopy. The analogous procedure was iterate for the other wrist. We observe that the scaphoid fracture was reduced ad lib along with the reduction of the carpal bones. So we performed simple regression of the leaveoveroverover scaphoid fracture using a 3.5 mm mini Acutrak headless coalition turn in finished the fracture line from a dorsal-proximal to a volar-distal direction. Intraoperative fluoroscopic control confirm anatomic reduction of the scaphoid fracture.. F inally, prototype radiograms were obtained and both wrists were immobilized in a niggling arm cheat ( Fig. 2 ). The patient noted sleep together relief of symptoms the day after surgery. The pain and the paresthesia that the patient complained preoperatively was relieved dramatically and the function recovered. The post-operative point was uneventful. Four weeks after surgery, the pour forths and the K-wires were outback(a). New determines were utilize for another 4 weeks when labor joint was visible on radiographs. The casts were removed eight weeks after surgery. There was radiographic reason of coupling of the scaphoid on the left side, but on the unspoilt side skiagraphy revealed slow up union of the scaphoid. The patient afterward underwent 3 months of intensifier range-of- relocation and muscle-strengthening exercises. Intermediate clinical and radiographic examinations were performed 6 and 12 months after surgery. At the two-year follow-up, the radiograp hs showed normal carpal bone relationships on both sides, have sex union of the scaphoid on the left side(Fig.3). Wrist motion on the left side was resplendent with 70 of volar flexion, 80 of dorsiflexion, full supination and pronation, full radial and ulnar deviation. The recompense wrist could achieve 60 of volar flexion and 70 of dorsiflexion, full supination and pronation, but with a lenient decrease in radial and ulnar deviation. The time lag strength of the right hand was 30 kg while that of the left side was 38 kg, measured with the Jamar ergometer (J.A. Preston, Jackson, Michigan) . Fig.3 Right wrist and Left wrist anteroposterior and lateral picture after two-years. At the two-year follow-up, the patient was symptom- lighten concerning median nerve functions. The patient was free of pain on the left side. On the right side there was soft pain with wrist motions due to non-union of the scaphoid.The patient was able to perform activities of daily backup and he had returned to all of his previous activities. The useable outcome was cracking on the left side, with a mayo wrist slay of 80/100. The working(a) outcome was satisfactory on the right side, with a mayonnaise wrist chump of 65/100. Radiographs of both wrists revealed no evidence of radiocarpal or midcarpal arthritis. No osteonecrosis of the lunate or the scaphoid was evident. The lunate position was correct, without signs of derangement. Anatomic relationships of the carpal bones were maintained. Discussion carpal bone fracture-dislocations are rarefied injuries thus their mixed bag and treatment are rather difficult. boney variants of this injury are common the trans-scaphoid perilunate fracture-dislocation constitutes 61% of all perilunate dislocations and 96% of fracture-dislocations. 4 The trans-scaphoid perilunate fracture-dislocation is an red carpet(prenominal) injury sustained due to force transmission finished and through a hyperextended wrist. 9,10 These injuries may be easy overlooked or misdiagnosed. 4 After a delay in diagnosing of several weeks or months, the clinical chance is poor compared with injuries that are case-hardened acutely. 11 According to the sort described by Herzberg et al., we initially diagnosed our patient in the delay phase. 4 Regarding the literature, the forethought of such injuries in case of delayed presentation is rare. 12,13 hoo-hah in this neck of the woods requires rapid re coalescence, as untreated perilunate dislocation will lead-in to serious alternative damage. 13,14 Perilunate fracture-dislocations are high-octane injuries, produced by wrist hyperextension. 3,15 There is rift of the palmar capsuloligamentous complex, starting line radially and propagating through the carpus in an ulnar direction. 3,15 This dislocation takes a transosseous avenue through the scaphoid resulting in a trans-scaphoid perilunate fracture-dislocation. 10 In trans-scaphoid perilunate dislocations the f ractured scaphoid is the initial destabilizing factor of the carpus. 16 Regarding the literature, we study that the mechanics of injury in our patient was giving up from a height on the outstretched hands. Treatment options before long used for perilunar instability patterns include closed in(p) reduction and cast immobilizing, closed reduction and transcutaneous pinning, and open reduction. As the knowingness of the anatomy and biomechanics of these injury patterns has evolved, authors have tended toward treatment approaches that attempt to regenerate the injured intrinsical and extrinsic carpal ligaments, that is, open techniques. 4,8,11 or so authors agree that closed reduction is the initial treatment of prize for trans-scaphoid perilunate fracture-dislocations. 2,8,17 In addition, treatment often requires intercarpal fixation within the proximal carpal row. most(prenominal) authors have concord that the key to a undecomposed clinical result in the management o f trans-scaphoid perilunate dislocation is the anatomic union of the scaphoid and the proceeds of proper alignment of the carpal bones. 17 In this case, we prefer a receptive reduction and intercarpal fixation with K-wires, as puff up as prat fixation of the scaphoid, because we didnt achieve a good fracture alignment after closed reduction . Gellman et al. suggested that anatomical reductions of the scaphoid, as well as the mid-carpal joint, and the restoration of the articulary surface of the lunate are the most important aspects determine the prognosis. 11 An open reduction save increases the risk of a scaphoid smear cater geological fault, whereas transcutaneous rump fixation of the scaphoid minimizes this risk. 3,17,18 In addition, a cockeyed fixation with a percutaneous screw can overly reduce the immobilization period and suffer for an front rehabilitation. Acutrak screw fixation allows earlier discontinuance of the cast than K-wire fixation. In our case, th e range-of-motion exercises of the wrist were started earlier after the initial operation. The nonunionized rate was relatively higher in the series that were treated by closed reduction. 19,20 In our case study the radiographs obtained two years after surgery revealed a non-union of the right scaphoid. We believe that the delay in treatment and perchance the malrotation of the scaphoid that we overlooked on the initial radiographs led to the interruption of the blood supply which was possibly responsible for(p) for the non-union of the scaphoid. Despite the non-union of the scaphoid, the usable outcome of our patient was satisfactory, with mild pain, good range of movement and good grip strength. Similarly, Herzberg et al. 4 reported that unsatisfactory radiographs did not equate to a poor clinical outcome. We planned to perform open reduction and internal fixation with grafting for the non-union of the right scaphoid. Conclusion As the injury have led bilateral dorsal trans-scaphoid perilunate fracture-dislocations,we consequently recommend minimally invasive techniques if an anatomical closed reduction anda percutaneous rigid fixation of the scaphoid is achieved on the intraoperative evaluations.
