To determine the bony outcomes of patients treated at our Institution after sustaining femur fracture and arterial injury, due to gunshot, in the ipsilateral limb, studied over a four-year period. The database at the Department of Vascular Surgery at our Institution was searched for cases that had sustained both arterial injury and femur fracture of the ipsilateral leg. Their case notes and X-rays were reviewed for the following:. Time line from injury to discharge. Procedure performed. Duration of external fixation. Complications (infection, iatrogenic vascular injury, amputation,. bony union achieved). Incidence of fasciotomy. During the period from 2002 to the end of 2005 there were 12 patients who qualified to be included in the audit group. Three of the 12 (25%) had to undergo a primary amputation upon arrival. The other nine cases underwent surgery. One of these received an intra-medullary device, another skeletal traction and the rest external fixation following the vascular surgery. Five of the 7 external fixation devices were converted to an intramedullary device in due course. All nine cases went on to union. There were no reported cases of iatrogenic vascular repair disruption. Of the 12, only three cases reported any infection. One case developed severe osteomyelitis of the femur. Primary vascular repair with temporary external fixation that was later converted into an intramedullary device (within 14 days) provided satisfactory results

The rate of arterial injury in trauma patients with pelvic ring fractures has been cited as high as 15%. Addressing this source of hemorrhage is essential in the management of these patients as mortality rates are reported as 50%. Percutaneous techniques to control arterial bleeding, such as embolization and REBOA, are being employed with increasing frequency due to their assumed lower morbidity and invasiveness than open exploration or cross clamping of the aorta. There are promising results with regards to the mortality benefits of angioembolization. However, there are concerns with regards to morbidity associated with embolization of the internal iliac vessels and its branches including surgical wound infection, gluteal muscle necrosis, nerve injury, bowel infarction, and thigh / buttock claudication. The primary aim of this study is to determine whether pelvic arterial embolization is associated with surgical site infection (SSI) in trauma patients undergoing pelvic ring fixation. This observational cohort study was conducted using US trauma registry data from the American College of Surgeons (ACS) National Trauma Database for the year of 2018. Patients over the age of 18 who were transported through emergency health services to an ACS Level 1 or 2 trauma hospital and sustained a pelvic ring fracture treated with surgical fixation were included. Patients who were transferred between facilities, presented to the emergency department with no signs of life, presented with isolated penetrating trauma, and pregnant patients were excluded from the study. The primary study outcome was surgical site infection. Multivariable logistic regression was performed to estimate treatment effects of angioembolization of pelvic vessels on surgical site infection, adjusting for known risk factors for infection. Study analysis included 6562 trauma patients, of which 508 (7.7%) of patients underwent pelvic angioembolization. Overall, 148 (2.2%) of patients had a surgical site infection, with a higher risk (7.1%) in patients undergoing angioembolization (unadjusted odds ratio (OR) 4.0; 95% CI 2.7, 6.0; p < 0 .0001). Controlling for potential confounding, including patient demographics, vitals on hospital arrival, open fracture, ISS, and select patient comorbidities, pelvic angioembolization was still significantly associated with increased odds for surgical site infection (adjusted OR 2.0; 95% CI 1.3, 3.2; p=0.003). This study demonstrates that trauma patients who undergo pelvic angioembolization and operative fixation of pelvic ring injuries have a higher surgical site infection risk. As the use of percutaneous hemorrhage control techniques increase, it is important to remain judicious in patient selection

Purpose: Vascular injuries occur in approximately 3% of all patients with major civilian trauma and peripheral vascular injuries account for 80% of all cases of vascular trauma. Upper extremity arterial injuries represents about 30% of all cases arterial trauma. The present study was designed to document and analyze the respective role of arterial damage and associated injuries on functional outcomes after upper extremity arterial trauma. Material and Methods: Excluding the arterial injuries resulting in immediate amputation there were 57 patients who sustained arterial trauma of the upper extremity. Their mean age was 33 years (range 4–68 years), and 40 were males and 19 were females. The most frequently injured vessel was the ulnar artery (42%) followed by the brachial artery (29.8%), radial artery (26.3%) and axillary artery (1.7%). Concomitant fractures or nerve injuries were present in 54% and 45% respectively. Results: An average of 5.6 hours elapsed between the time of injury and the time of vessel reconstruction. The most common method of surgical management was end to end anastomosis. Twenty one autogenous vein grafts were employed. Primary nerve repair was carried out in 29 patients and in another 18 secondary repair was performed. None of patients had any residual compromise from the arterial injury. Discussion: Vascular injuries are potentially limb threatening. Improvements in the technical ability to revascularize injured extremities and advances in microsurgery, resulting in the low present day limb loss rate associated with attempted vascular repairs. Associated injuries, rather than vascular injuries, cause long-term disability in the trauma of the upper extremity. Persistent nerve deficits, joint contractures and pain are principal reasons for functional impairment

Major upper limb arterial injuries sustained in combat are associated with significant trauma. We analysed the survival and complication rates following upper limb vascular injury in Iraq and Afghanistan (2004–2014). Fifty-two soldiers sustained 59 major arterial injuries in 54 limbs. Axillary artery injuries were more likely to be caused by gunshot wounds (86%), whilst brachial and ulnar artery injuries were primarily associated with blasts (72% and 87% respectively); no such correlation was identified with radial artery injuries. Apart from three temporary shunts, all vascular injuries were treated definitively in the local field hospital before repatriation. Proximal injuries were predominantly treated with long saphenous vein grafts and distal injuries with ligation. One soldier required an immediate amputation following failed LSV grafting, however no amputations followed repatriation. There were five identified graft failures (21%), although these were not associated with subsequent perfusion issues. There were no graft failures following temporary shunting. Associated nerve injuries often required operative intervention and have a guarded outcome. 100% of radial fractures went onto non-union if combined with a radial artery injury. Successful immediate re-perfusion of a vascular compromised upper limb correlates with excellent long-term limb survival, despite a significant number of grafts developing secondary failure

Purpose of study: To report arterial injury related to reference pin placement in computer navigated knee arthroplasty. Methods and results: Our practice is to use computer navigation for all primary total knee replacements (TKR). We use a passive reflector-based system (Brain-lab, Feldkirchen, Germany), with pin fixation of the reference arrays. For the femoral array two threaded pins are inserted anteriorly with the knee in flexion and are placed as proximally as the tourniquet will allow. The pins fixation is bicortical in order to maintain good stability for the duration of surgery. A 58 year old man underwent TKR with computer navigation using our standard technique. His post operative course was characterized by thigh swelling and pain. He was discharged on postoperative day 3 with a range of movement of 0–30°. 3 days later he was readmitted with increasing thigh pain and swelling. A quadriceps haematoma was suspected and a computerized tomography scan with intravenous contrast was performed. This showed active bleeding into the femoral canal at the site of the pin tract from a branch of the profunda femoris artery as it entered the linea aspera and a large haematoma within the quadriceps muscle centred over the pin tract anteriorly. There was no extraosseous posterior haematoma. An 800ml haematoma was drained and two small fragment cortical screws were inserted into the pin tracts. Unicortical screws were used to minimize the risk of causing posterior bleeding. Arterial injury has not been reported before in this setting. The previously reported complications are: pin breakage, superficial wound infection, interference with line of sight, broken pelvic drill, prolonged operation time and prolonged tourniquet time. Conclusion: This report highlights an important complication of computer navigated TKA which needs to be taken into consideration when deciding upon whether to use computer navigation

Objective: To assess the impact of EPP on physiological parameters in hemodynamically unstable patients with blunt pelvic trauma. Methods: Of 661 patients treated for pelvic trauma, 18 consecutive patients in shock underwent EPP with the intent to control massive pelvic bleeding. These patients constituted the study population. Data collected from the medical records and the Ullev̊l Trauma Registry included: demographics, fracture classification, additional injuries, blood transfusions, surgical interventions, angiographic procedure, physiological parameters and outcome. An association between continuous variables was calculated using the Spearman correlation coefficient. A comparison between means was calculated using the t-test. Results: Mean patient age was 44 years (range 16–80). ISS 47 (9–66). 39 % had non-measurable blood pressure at admission. Survival rate within 30 days was 72% (13/18) and correlated inversely to the age of the patient (p=0.038). Only one non-survivor died of exsanguination from multiple bleeding foci. A significant increase in systolic blood pressure (p=0.002) and hemoglobin count (p=0.012) was observed immediately after EPP. Arterial injury was observed in 80% of patients who underwent angiography after EPP. Conclusions: 30-day survival rate after EPP was 72 %. A significant increase in systolic blood pressure and hemoglobin count was observed immediately after EPP, indicating that EPP as part of a multi-interventional resuscitation protocol may be life-saving in patients with exsanguinating pelvic injury. However, the high rate of arterial injuries seen after EPP indicates that the procedure should be supplemented with angiography once the patient is stabilized for transfer to the angiography suite

Aims: To evaluate the outcome after early angiographic embolization in pelvic ring injuries associated with massive bleeding. Methods: We evaluated prospectively 32 consecutive patients. Special attention was paid to the þndings in angiography, the reliability of embolization, and the þnal result (survive or death). The causes of deaths were evaluated as well as the parameters correlating to this. Results: Angiography showed an isolated arterial injury in 16 (50%) and multiple arterial injuries also in 16 patients (50%). 9 patients had bilateral bleeding. Internal iliac artery and/or its main branches was the source of bleeding in 27 (85%), external iliac artery or its main branches in 2 (6%), and branches of both internal and external iliac arteries in 3 patients (9%). The embolization was successful in all cases. 11 patients (34%) died. The early deaths (< 24h) were the result of massive bleeding in 4 out of 5 patients. One died to cardiac failure. Six late deaths were the result of MODS. All the died patients had more than one bleeding artery, and 6 had bilateral bleeding. The non-survivors had more severe injuries (mean ISS 51) and were older (mean age 50,2 yrs) than the survivors (mean ISS 41; mean age 43,9 yrs). Conclusions: Angiographic embolization is an effective and life saving procedure. It should be considered in hypotensive patients with unstable pelvic ring injuries who remain haemodynamically unstable following adequate resuscitation with component therapy and external þxation

The treatment of the multi-trauma, hemodynamically unstable patient, with pelvic fractures is a major challenge for the trauma team. The use of selective embolization, in early stage when hemodynamic instability persists despite control of other sources of bleeding, is well established. In these cases bleeding from an injured artery, cannot be controlled through indirect means such as an external fixation device, and must be directly addressed, through laparotomy and retroperitoneal packing or direct embolization of the bleeding artery. This procedure is part of the C phase of the ATLS, and therefore must be carried out in an emergency setup requiring a well trained team that can be alerted 24 hours a day. We present our experience and preferred protocol for the treatment of these complex injuries. Material and Methods: Between the years 2000 and 2004, 732 patients with pelvic fractures were treated in our center. Of these, 11 patients with complex pelvic fractures required emergency arteriography and embolization. All the cases involved high energy injuries, eight motor vehicle accidents, two falls from height and one crush injury. The average age was 32 (range 21 to 78). The pelvic fracture type was an anterior posterior mechanism in eight cases where the artery injured was the pudendal artery. In three cases iliac wing injury in a lateral compression or sheer mechanism, caused a gluteal artery injury. Timing of treatment: in 5 cases angiography was performed directly after an initial CT, in 4 cases the embolization was performed following an emergent laparotomy. In the remaining two cases, instability was recognized later in the course of treatment, one following amputation of a mangled leg and the second after secondary deterioration in a head injured multi-trauma patient. Five patients went through pelvic fixation by an external fixation device, applied prior to angiography of which two were surgically applied and three were treated with a pelvic belt. In five patients no pelvic fixation was needed either initially or definitively. Discussion: When available angiographic embolization can be used affectively in these selected cases. Pelvic fractures can present with arterial injury even with a clinically stable pelvic ring. An arterial injury must be considered in all severe pelvic injuries regardless of the pelvic ring stability. We recommend strongly to use the belt as an intermittent way of controlling the hemodynamic instability and not to delay direct means of hemorrhage control such as laparotomy or embolization – if there is a team ready in the hospital. We must consider that the delay in treatment, short as it may be, needed for application the external fixation devices, may be crucial for the survival of the patient

Aims

Our objective was describing an algorithm to identify and prevent vascular injury in patients with intrapelvic components.

With the aim of identifying appropriate treatment and diagnosis, this paper discusses 12 of 107 elbow dislocations and 56 elbow fracture dislocations seen over four years. One patient presented with arterial injury, two with olecranon fractures and dislocation, and three with radial head, olecranon and coronoid fractures. One patient had an intra-articular fracture, two had collateral ligamentous injuries and two had radial head fractures and dislocations. Depending on treatment, the results can be very poor or excellent. An awareness of the pitfalls in dislocations and fracture dislocations of the elbow is necessary to prevent poor outcomes

Objective:. To observe the incidence of intra-operative vascular injuries during anterior cervical decompression and fusion (ACDF). Secondly, management and monitoring of the outcome post vascular injury during ACDF. Methods:. This a prospective study. A review of all spinal patients' records was performed from June 2006 to April 2011. A comprehensive literature review was also utilized. Inclusion criteria – all patients had ACDF post trauma. All non-traumatic cases were excluded. Results:. The study consisted of 55 patients; 15 were females and 40 were males. The age distribution was 23–65 years. Two patients were excluded due to non-traumatic causes. Of the remaining 53 patients, four sustained intra-operative vascular injuries during ACDF surgery. All 4 patients had corpectomies, and one case was an iatrogenic injury. The commonly injured vessel during the ACDF surgery was the left vertebral artery. Haemostatic control was achieved via tamponade and haemostatic agents. The left common carotid was iatrogenically injured in one case and was treated by microvascular repair. Three patients were treated with antiplatelet therapy for three months duration. The patient with an iatrogenic injury was treated with anticoagulation therapy for three months duration. All computerized tomographic angiograms at three months follow up illustrated patent vessels. Conclusion:. There is an increased incidence of intra operative vascular injuries during ACDF associated with corpectomies. It is essential to be aware of the low incidence of intra operative arterial injury during ACDF and to have a management approach, such as tamponade or microvascular repair. Anticoagulation and antiplatelet therapy is effective in decreasing the complications of vascular injuries post ACDF

To evaluate efficacy and outcome of embolisation following pelvic ring injuries in patients presented with ongoing hypovolaemic shock. Between 2000 and 2003, 200 poly-trauma patients presented in our institutions following pelvic ring injuries. Those with ongoing hypovolaemic shock who were treated within 24h of admission with embolisation were included in this study. Demographics, mechanism of injury, ISS, type of pelvic ring fracture, arterial source of bleeding, hours from injury to embolisation, and outcome were all recorded prospectively. Out of the 200 treated in our institutions 17 (8.5%) underwent angio-embolisation. The mean age of the patients was 37 (14-70) and the mean ISS was 29. Distribution of pelvic ring injuries included: 3LC, 7APC, 7VS. The mean time from injury to embolisation was 15 hours. 8/17 patients were initially treated with an external fixator. The distribution of arterial injuries was: 7 superior gluteal arteries, 8 internal iliac arteries, 1 obturator artery and 1 internal pudental artery. The mean number of units transfused prior to embolisation was 22 (range 6-50). Mortality rate was 4 (23%) out of 17 embolised patients. Angio-embolisation for pelvic ring injuries occurred in 8.5% of our study population. This study indicates that only a small proportion of patients required embolisation secondary to arterial bleeding. The overall survival rate was in accordance to published international experience. Embolisation should be considered as a valid adjunct in some selected group of patients with pelvic fractures where ongoing bleeding refractory to other treatment modalities is present

Background: Lumbar disc replacement is a good alternative to fusion in young patients with degenerative disc disease or discogenic back pain. Despite the increase in the use of anterior lumbar disc replacement, there has been little published data of the specific types and frequencies of the complications associated with its use. Aims & Methods: Purpose of the study is to retrospectively study the perioperative complications associated with CHARITÉ® Artificial Disc replacement. The lumbar spine is retroperitoneally approached, viscera and major vessels retracted and the disc replaced. We reviewed the operative and hospital records of 54 charite disc replacements done by the senior author from 2004 till September 2006. Results: The study group had 23 men and 31 women with a mean age of 38 years (range 31–47). Preoperative diagnosis was degenerative disc disease in 42 patients (78%); discogenic back pain in 12 patients (22%). The most common level replaced was L4/5 (48%) followed by L5/S1 (35%). The most common complication during the procedure was venous injury involving one of the left iliac vein tributary (9 patients, 16%). There was no arterial injury. The median blood loss was 450ml (100–1500ml). There was peritoneum breach in six patients, but no case of bowel, ureter, and bladder or kidney injury. There were two incidences of significant post operative ileus and one developed S1 radiculopathy from lateral disc placement. One developed incisional hernia and two patients had to be revised to fusion. Retrograde ejaculation was reported in 3 patients. No incidence of epidural vein bleed, CSF leak, infection, paraplegia or death. Conclusions: Anterior spinal surgery is a relatively safe procedure with a lower complication rate than was previously reported. Vascular injury was the most frequent complication. The incidence of autonomous dysfunction affecting pelvic floor function appears to be under-estimated and needs further study

Objectives. The risk of infection after type III° open fractures is high (10–50%). Preemptive antibiotic therapy may prevent posttraumatic infection and improve the outcome. Recommendations about the type and duration of antibiotic vary among the institutions and it remains unclear whether gram-negative bacilli or anaerobs need to be covered. In Europe, the most commonly recommended antibiotic is amoxicillin/clavulanic acid. We retrospectively analyzed microbiology, characteristics and outcome of patients with open type III° fractures treated at our institution. Methods. Between 01/2005 and 12/2009 we retrospectively included all type III grade open fractures of the leg at our institution classified after Gustilo (JBJS Am 1976) into type IIIA (adequate soft-tissue coverage of bone with extensive soft-tissue laceration or flaps), IIIB (extensive soft-tissue loss with periosteal stripping and bone exposure), and IIIC (requiring arterial injury repair). Demographic characteristics, clinical presentation, microbiology, surgical and antibiotic treatment and patient outcome were recorded using a standardized case-report form. Results. 30 cases of patients with type III° open fractures were included (25 males, mean age was 40.5 years, range 17–67 years). 27 fractures (90%) were located on the lower leg and 3 (10%) on the upper leg. 24 cases (80%) were high-energy and almost half of the patients (n=16, 53%) had a polytrauma. Microbiology at initial surgery was available for 19 cases (63%), of which 10 grew at least one organism (including 8 amoxicillin/clavulanic acid-resistant gram-negative bacilli [GNB], 7 amoxicillin/clavulanic acid-resistant Bacillus cereus), 11 were culture-negative. Preemptive antibiotics were given in all cases (100%) for an average duration of 8.5 days (range 1–53 days), the most common antibiotic was amoxicillin/clavulanic acid in 60 % (n=18). 11 cases just received preemptive antibiotic treatment, in 19 of 30 cases the antibiotic therapy was changed and prolonged. Microbiology at revision surgery was available for 25 cases and 22 grew at least one pathogen (including 32 amoxicillin/clavulanic acid-resistant gram-negative bacilli and 10 amoxicillin/clavulanic acid-resistant Bacillus cereus), 3 were culture-negative. Conclusions. At initial surgery, most common isolated organisms were coagulase-negative staphylococci (43%), Bacillus cereus (23%), and gram-negative bacilli (27%), and others (7%) of which 48% were resistant to amoxicillin/clavulanic acid. At revision surgery, isolated organisms were gram-negative bacilli (64%), Bacillus cereus (20%), and others (16%) of which 88% were resistant to amoxicillin/clavulanic acid. The spectrum of amoxicillin/clavulanic does not cover the most common isolated organisms

Aims: To describe the clinical characteristics, radiological classiþcation and management of 30 patients with severe pelvic injuries necessitating arterial embolization due to uncontrollable haemorrhage. Patients and methods: A prospective registration of patients admitted to our Level I- trauma hospital with pelvic fractures during a six year- period (1996-2002). Annually 168 patients had pelvic and acetabular fractures. The study group constituted of thirty of these patients where uncontrollable haemorrhage necessitated angiographic embolization of intrapelvic arteries. Results: 21 of the patients were male, on average 36 years old. All patients were subjected to high-energy traumas. Four had open pelvic fractures. One patient died in the initial phase due to multiple injuries. Average ISS score was 43,7. All patients had additional injuries, 50% were multitraumatized. Isolated sacral and acetabular fractures occurred in 5, the rest had pelvic ring injuries, 14 type B- and 11 type C-fractures. Deþnitive orthopaedic treatment was performed in 20 patients. There was a delay of 9 hours from admittance to embolization. Patients received 6,8 units prior to arrival at our unit, 15,4 units prior to embolization, 2 units 24-hours after embolization and 17,0 units from embolization to discharge. A total of 33, 9 units of erytrocytes was transfused at our unit. Time in angiography laboratory was 138 minutes. Branches of the internal iliac artery were affected in 28 patients, the superior gluteal artery being most frequently injured. Embolization was not effective in achieving haemostasis in 3. Conclusions: Pelvic fractures necessitating embolization due to uncontrollable haemorrhage are a result of high energy injuries and associated injuries are common. Arterial injuries associated with unstable pelvic haemorrhage are often due to injuries to branches of the internal iliac artery and early percutaneous embolization of these branches seems to control bleeding effectively

A previous audit of New Zealand Joint Registry data showed that, overall, OXF UKA had over three times the seven–year revision rate (RR) compared with TKA. Where the RR was calculated for surgeons performing one or more OXF UKA per month, however, the RR was comparable to that for all–surgeon TKA (Hartnett et al, NZOA ASM, 2007). To audit and compare revisions of OXF UKA and TKA performed by one surgeon, as recorded in the New Zealand National Joint Registry, and to highlight a complication of OKF UKA unreported in the literature. The data from a personal series of 177 consecutive medial Oxford (Phase three) cemented UKAs entered in the Registry from January 2000 to December 2007 was analysed. The number and reasons for revision of the cohort was compared with a similar personal cohort of 229 consecutive cemented TKAs performed over the same period. Comparison was also made between this personal data with that for all surgeons recorded in the Registry. OXF UKAs were performed at a mean rate of 1.8 procedures per month. The prime indication was antero-medial osteoarthritis: valgus stress x-rays performed routinely had to establish adequate thickness of lateral articular cartilage and ACL had to be competent before the UKA was preferred to TKA. Fifty six (31.6%) of the 177 operations were performed as part of bilateral procedures under the one anaesthetic. Two OXF UKAs were revised to TKA. In neither was there failure of fixation or integrity of the prosthesis: one case was revised for unexplained pain where OXF UKA was for post–traumatic medial OA. The 2nd revision followed recurrent haemarthrosis and subsequent joint destruction: arteriography found no arterial injury. The RR for personal OXF UKA was therefore 1.1%, which compares with personal TKA RR of 2.2% (difference not significant p=0.42). The RR for all OXF UKAs in NZ was 5.6%, and that for TKA was 1.8%. The difference between personal and national RR for OXF UKA is significant (p=0.010), and that for TKA is not (p=0.63). Since 2000, two other revisions of OXF UKA outside the studied cohort both followed recurrent haemarthrosis causing joint destruction. The results of OXF UKA reported here confirm that an early revision rate comparable to TKA is achievable when this surgery is performed relatively frequently by the surgeon. Recurrent haemarthrosis occurring later after early successful OXF UKA surgery is not recorded in the English literature. It has been the most frequent reason for revision (three of four revisions)

Modern concepts in paediatric fracture respect individual, social and economic needs:. the patient’s demand for early mobility and capability to play. the requirement to achieve an optimal end result (no posttraumatic deformity, full range of motion, no leg length discrepancy) with a minimum of total expenditure and costs: primary treatment should be the definitive treatment. Thus, redo-procedures, unnecessary irradiation, and long hospital stays are prevented. the spontaneous remodelling capacity should be anticipated for each specific fracture and be part of the treatment algorithm of fractures of the upper extremity. In the lower extremities a long lasting remodelling period leads to stimulation of the adjacent physis and thus to posttraumatic leg length differences. The decision between conservative and operative treatment is based on the radiological assessment of fracture stability. Fractures with fragments in contact and at most with some angulation but no shortening may be termed stable. Conservative treatment on an outpatient basis is adequate: plaster immobilization and wedging of the plaster in case of a primary or secondary angulation. Fully displaced fractures or long oblique fractures with a strong tendency for shortening as well as comminuted fractures are unstable. Stable fixation with a child-adapted implant is required: closed reduction, minimal approach, satisfying scars, early full weight bearing, short hospital stay, and a minimal procedure for metal removal are achieved either by external fixation or elastic intramedullary nailing dependent on the fracture pattern and the surgeon’s preferences. Humeral shaft fractures are the domain of non-operative treatment: immobilization e.g., with a U-plaster followed by functional bracing (Sarmiento) is efficient and more comfortable than a heavy hanging cast. Retrograde intramedullary nailing is indicated in open fractures, multiple injury patients, arterial injuries and compartment syndromes, or if conservative treatment does not lead to a satisfactory alignment. Concomittant radial nerve palsies: since natural history is excellent, observation instead of primary exploration is recommendable. Forearm: in case of complete fractures, closed reduction and plaster immobilisation is only justified if one of both bones is stable. If not, primary elastic intramedullary nailing prevents posttraumatic deformities and loss of function. Femur: Non-displaced fractures (less than 10° angulation in the sagital plane, no varus or valgus deformity, no malrotation) as well as displaced fractures in children younger than four years can be treated with a hip spica. In older children closed reduction followed by external fixation or elastic intramedullary nailing provides early stability and a quick return to play and school. Shortening and angulations with a subsequent high remodelling activity should be avoided in order to prevent femoral overgrowth. Lower leg: Most isolated tibial fractures (intact fibula) are managed conservatively in a long leg plaster. Radiological monitoring is recommended to detect secondary varus deformites which can be easily reduced by wedging of the plaster after 8 to 10 days. Fully displaced transverse tibia fractures and unstable fractures of the tibia and fibula – oblique fractures with shortening or fully displaced fractures – are either stabilised by external fixation or elastic intramedullary nailing

Objectives

The surgical challenge with severe hindfoot injuries is one of technical feasibility, and whether the limb can be salvaged. There is an additional question of whether these injuries should be managed with limb salvage, or whether patients would achieve a greater quality of life with a transtibial amputation. This study aims to measure functional outcomes in military patients sustaining hindfoot fractures, and identify injury features associated with poor function.
