Bilateral Trans-Scaphoid Perilunate Fracture Dislocation

Bilateral Trans-Scaphoid Perilunate Fracture Dislocation BILATERAL TRANS-SCAPHOID PERILUNATE FRACTURE DISLOCATION OF THE CARPUS. (CASE REPORT) Abstract: 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 reduction and fractures by internal fixation. The functional outcome was satisfying after two years of follow-up. Introduction: Trans-scaphoid perilunate fracture-dislocations are relatively uncommon. 1 These are the most common form of the complex carpal dislocations 2,3 causing marked disruption of the carpal anatomy. Time from injury to treatment (delay in treatment), anatomic classià ¯Ã‚ ¬Ã‚ cation, and open or closed nature of the injury are the major factors that determine the clinical outcome in trans-scaphoid perilunate fracture-dislocations. 4,5 Late presentation combi ned with missed diagnosis often causes critical delay in the treatment of these injuries. If the acute phase is missed, then some authors recommend alternative procedures such as wrist arthrodesis and proximal row carpectomy which are relatively mutilating surgeries that leave a significant functional deficit. 4,6,7 The acute phase is defined as the first week after injury, whereas the delayed phase is the period between the seventh and 45th day and after 45 days the injury is said to be in the chronic phase. 4 We report the case of a patient who referred to our department two weeks after the initial trauma with bilateral dorsal trans-scaphoid perilunate fracture-dislocations of the carpus. Anatomic reduction, percutaneous pin fixation of the carpus and fixation of scaphoid fractures of both wrists were performed by opened reduction under fluoroscopic control. Presentation of case: A 21-year-old, right-hand-dominant man sustained an isolated injury to his both wrists after a fall from a height of approximately 4.5 m. The carpal injuries of both wrists were missed initially and both wrists had been bandaged for two weeks after the trauma. He was referred to our department two weeks later with increasing pain. The patient reported that he fell on his outstretched hands with both wrists in extension. Both wrists were deformed in marked dorsiflexion, painful, swollen, and tender to palpation, with limitation of movement. The patient complained of paresthesia in both of his hands. On physical examination, meticulous cutaneous sensory mapping was performed of both hands to determine the area of decreased sensation. This was done with the use of the sharp end of a paperclip while applying a constant pressure. This revealed minor numbness in the median nerve distribution area of both hands (thumb, index, middle finger, and the radial side of the ring finger). The two-point discrimination was normal on both sides. The mobility of the fingers was normal but pai nful, and there was a slight decrase in grip strength of both hands. Motor power in abductor pollicis brevis and opponens pollicis muscles was full (5/5) on both sides. The Tinel’s sign was negative over the carpal tunnel in both sides. The findings of the patient led us to think that there is not any condition like acute carpal tunnel syndrome due to fracture-dislocation.We thought that the numbness of the patient was due to temporary traction injury of the median nerve caused by dislocation on both sides. The vascular status was normal on physical examination. Study of the anteroposterior, oblique and lateral plane radiographs showed that the patient had bilateral dorsal trans-scaphoid perilunate fracture-dislocations of the carpi ( Fig. 1 ). According to the classification described by Herzberg et al., the fracture-dislocations were trans-scaphoid as path of trauma and Stage 1 as displacement of capitate on both sides. 4 The patient was informed about his pathology and a dvised to undergo surgery. If possible the patient’s preference was closed treatment. Therefore, we initially recommend closed reduction and percutaneous fixation. However, if this was not possible or in the situation of a failure we informed him about the open procedure. Under general anesthesia, a closed reduction was attempted with traction manoeuvre described by Tavernier 8 under fluoroscopic control. The reduction was not satisfactory,we opted for the open reduction by posterior approach.After anatomical reduction was achieved, intercarpal fixation was applied to carpal bones using three K-wires. The first K-wire was applied to scaphoide- lunate, the second K-wire was applied to- lunate-triquetrum and the third K-wire was applied to capitatum-lunate. After the procedure, reduction and fixation of carpal bones was confirmed under fluoroscopy. The same procedure was repeated for the other wrist. We noticed that the scaphoid fracture was reduced spontaneously along with t he reduction of the carpal bones. So we performed   fixation of the left scaphoid fracture using a 3.5 mm mini Acutrak headless compression screw through the fracture line from a dorsal-proximal to a volar-distal direction. Intraoperative fluoroscopic control confirmed anatomic reduction of the scaphoid fracture.. Finally, standard radiograms were obtained and both wrists were immobilized in a short arm cast ( Fig. 2 ). The patient noted complete 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 period was uneventful. Four weeks after surgery, the casts and the K-wires were removed. New casts were applied for another 4 weeks when union was visible on radiographs. The casts were removed eight weeks after surgery. There was radiographic evidence of union of the scaphoid on the left side, but on the right side radiography revealed delayed union of the scaphoid. The patient subsequently underwent 3 months of intensive range-of-motion and muscle-strengthening exercises. Intermediate clinical and radiographic examinations were performed 6 and 12 months after surgery. At the two-year follow-up, the radiographs showed normal carpal bone relationships on both sides, complete union of the scaphoid on the left side(Fig.3). Wrist motion on the left side was excellent with 70 ° of palmar flexion, 80 ° of dorsiflexion, full supination and pronation, full radial and ulnar deviation. The right wrist could achieve 60 ° of palmar flexion and 70 ° of dorsiflexion, full supination and pronation, but with a mild decrease in radial and ulnar deviation. The grip strength of the right hand was 30 kg while that of the left side was 38 kg, measured with the Jamar dynamometer (J.A. Preston, Jackson, Michigan) . Fig.3 Right wrist and Left wrist anteroposterior and   lateral view after two-years. At the two-year follow-up, the patient was symptom-free concerning median nerve functions. The patient was free of pain on the left side. On the right side there was mild pain with wrist motions due to non-union of the scaphoid.The patient was able to perform activities of daily living and he had returned to all of his previous activities. The functional outcome was good on the left side, with a Mayo wrist score of 80/100. The functional outcome was satisfactory on the right side, with a Mayo wrist score 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 instability. Anatomic relationships of the carpal bones were maintained. Discussion Carpal fracture-dislocations are rare injuries; thus their classification and treatment are rather difficult. Osseous 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 uncommon injury sustained due to force transmission through a hyperextended wrist. 9,10 These injuries may be easily overlooked or misdiagnosed. 4 After a delay in diagnosis of several weeks or months, the clinical prognosis is poor compared with injuries that are treated acutely. 11 According to the classification described by Herzberg et al., we initially diagnosed our patient in the delayed phase. 4 Regarding the literature, the management of such injuries in case of delayed presentation is rare. 12,13 Dislocation in this region requires rapid realignment, as untreated perilunate dislocation will lead to serious secondary damage. 13,14 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 perilunate fracture-dislocation. 10 In trans-scaphoid perilunate dislocations the fractured scaphoid is the initial destabilizing factor of the carpus. 16 Regarding the literature, we believe that the mechanism of injury in our patient was fall from a height on the outstretched hands. Treatment options currently used for perilunar instability patterns include closed reduction and cast immobilization, closed reduction and percutaneous pinning, and open reduction. As the awareness of the anatomy and biomechanics of these injury patterns has evolved, authors have tended toward treatment approaches that attempt to repair the injured intrinsic and extrinsic carpal ligaments, that is, open techniques. 4,8,11 Most authors agree that closed reduction is the initial treatment of choice for trans-scaphoid perilunate fracture-dislocations. 2,8,17 In addition, treatment often r equires intercarpal fixation within the proximal carpal row. Most authors have agreed that the key to a good clinical result in the management of trans-scaphoid perilunate dislocation is the anatomic union of the scaphoid and the restoration of proper alignment of the carpal bones. 17 In this case, we prefer a opened reduction and intercarpal fixation with K-wires, as well as screw fixation of the scaphoid, because we didn’t 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 articular surface of the lunate are the most important aspects determining the prognosis. 11 An open reduction further increases the risk of a scaphoid blood supply interruption, whereas percutaneous screw fixation of the scaphoid minimizes this risk. 3,17,18 In addition, a rigid fixation with a percutaneous screw can also reduce the immobilization period and allow for an earlier rehabilitation. Acutrak screw fixation allows earlier discontinuance of the cast than K-wire fixation. In our case, the range-of-motion exercises of the wrist were started earlier after the initial operation. The nonunion 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 maybe 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 the non-union of the scaphoid. Despite the non-union of the scaphoid, the functional 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 f ixation with grafting for the non-union of the right scaphoid. Conclusion As the injury have led bilateral dorsal trans-scaphoid perilunate fracture-dislocations,  we therefore recommend minimally invasive techniques if an anatomical closed reduction and  a percutaneous rigid fixation of the scaphoid is achieved on the intraoperative evaluations.

Should American Soldiers have Invaded into the Irak War Essay

Should American Soldiers have Invaded into the Irak War - Essay Example activities to religiously aggravated 'jihad.' There is currently a self-governing Iraqi regime, and a contract in place to get rid of a considerable number of US military troops from the state. President Bush argued all through the two terms of his administration that the warfare in the country Iraq was a front procession in a war in opposition to global violence and terrorism. This belief was contemplated annually in special foundational addresses, and brought about substantial debate in the U.S and around the world. This essay will cover up the reasons as to why the American soldiers shouldn’t have invaded into Iraq. At the present it is finally recognized that there were no organic associations between Al Qaeda and Iraq in 2003, nor were artillery or weapons of mass obliteration and destruction ever found. So the question which arises is that should American soldiers have invaded into the Iraq War? A number of people think that the war was a fair and just route, while on th e other hand many believe that it was an intended endeavor by the American government to guard their economic wellbeing. This essay will draw attention to the two aspects of the debate that have been carried out in recent times. Individuals that defended this confrontation, particularly those that admire George .w. Bush state that if Iraq is not calmed down or stabilized, it could turn out to be a ground for terrorist breeding and a secure location for Osama Bin Laden or one more Saddam. The truth remains that the American armed forces that marched into Iraq failed to present the weapons they declared Hussein had his hands on. If the government of the United States truly planned to get rid of leaders who crush or trample upon the rights of humans or of their nation, Saddam must not have been the single target while at the moment of the attack. In my own opinion, American attack on Iraq was established on economic motives. US administration had the oil in mind which is abundantly fou nd in Iraq, and that was the purpose for execution the attack even without the complete agreement or support of the UN Security Commission. An attack on Iraq for the intention of "government transformation" would not be an officially authorized war if one considers the international law. As stated by Mohammad Taghi â€Å"Article 2(4)  of the UN Charter states that All Members shall refrain in their international relations from the threat or use of force against the territorial integrity or political independence of any state, or in any other manner inconsistent with the Purposes of the United Nations." Random assassinations, use of grenades, dozens of aggressive groups, and an intensified feeling of insecurity and depression troubles Iraq. The proof of enveloping and relentless chaos is all over the place, from the official figures of mortality to extended approximations of numerical results, from the news of families abandoning hazardous areas by the amount of tens of thousands to the demolishing of governance. As stated by Thomas G. Manken â€Å"The lethal fighting is all-pervading, but without an evident front or a visible strategy and for those reasons, among others, it is poorly understood.† Bombing of nationals population is a type of violence and terrorism  even more repugnant comparative to low-tech terrorism street killing and bombing of innocents. Opponents of the attack argued that it lead to the loss of hundreds of Iraqi nationals and military in addition to

Nietzxche, Friedrich. On the use and abuse of History for Life - Essay Example He was the vizier of the fourth dynasty during the reign of pharaoh Sneferu. Therefore, the writings are assumed to have been written between 2613-2589 B.C. The ancient writers did not specifically put the date of writing of the teachings but they gave the period and the king who reigned at that time. This information is used to determine age and time of the writing. The writing is categorized as wise sayings because they were written to guide the Pharaoh’s children on how they were to live and rule. According to the Egyptians, the writings are teachings which guide them in their daily ventures. The writing of these teachings took place in the Pharaoh’s palace, where their children were being taught. 2. †¦of the tree of knowledge of good and evil, thou shalt not eat of it; for in the day that thou eatest thereof thou shalt surely die. The title in which the above quote falls is creation, though others may group it as commandment. It can be argued to be creation sin ce it comes after Man and Woman have been created. On the other hand, it is said to be a commandment since it is an instruction to the created being on what they should and should not do. The commandment has more weight since it has punishment onto it that if they do not follow they will surely die. It was later found out that disregard of the instruction led to punishment and expulsion out of the garden. Thus, the quote is a command given to Adam and Eve by God in the Garden of Eden after they were created. The quote is found in the Bible, the book of Genesis chapter 2 versus seventeen. The writings were written years later by Moses despite the occurrence of the event in 4004 B.C when creation is believed to have taken place. Moses wrote the book of Genesis and grouped it with four others, naming it the book of Torah. The quote offers teaching to the believers on obedience and signifies the belief in one God to give them orders. The quote is religious due to its nature of involving beings and Supernatural forces. Moses wrote the book while in the desert with the Israelites as they were moving from Egypt into the Promised Land. 3. God created man in his own image, in the image of God created He him; male and female created He them. The quote above is extracted from creation. It justifies the existence of man as not from the natural causes but thoughtfully designed into existence by a Supernatural being. The book was written by Moses while in the desert with his fellow Israelites after running from Egypt, where they had served as slaves. The quote was used by Moses to remind the Israelites that they were created. It is extracted from the books of Moses known as the Torah, specifically the book of Genesis. The Quote was Jewish and is also used in the Christian context among those who believe in creation. The quote was said in the Garden of Eden, where the Bible states to have been the place where God began the creation. The event, therefore, occurred in 4004 B.C , the period in which it is believed the creation took place. It is found in the Bible, from the book of Genesis chapter one versus twenty seven (Genesis 1:27). The quote explains the work carried out in the sixth day of creation to crown the work that took a week; work that made the whole world. It denotes end of the creation act which was creating man. It denoted the end of the creation. The quote is categorized as religious, appreciating the existence of
