Orthopaedic injuries in the knee are often associated with vascular injury. When these vascular injuries are missed devastating there are devastating outcomes like limb ablation. Pulse examination in these patients is not sensitive to exclude vascular injuries. That often lead to clinicians opting for Computed Tomography Angiogram (CTA) to exclude vascular. this usually leads to a burden in Radiology Department. This study aimed to evaluate the prevalence of vascular injury in patient with orthopaedic injury in the knee. The computed tomography (CT) done in patients with distal femur fracture, knee dislocation and proximal tibia fractures were retrieved from the picture archiving and comunication system (PACS). The CTs were done between June 2017 and June 2022. The computed tomography angiogram (CTA) reports were reviewed to determine cases that vascular injury. A sample size of 511 cases was collected. 386 cases were done CTA and 125 cases were not done CTA. There were 218 tibial plateau fractures, 79 knee dislocations, 72 distal metaphyseal femur fractures, 61 floating knees, 55 distal femure intraarticular and 26 proximal metaphyseal tibia fractures. The mechanisms of injury in these were gunshot, fall from standing height, fall from height, MVA, MBA, PVA and sports. Prevalance was 9.17% (47) of the total injuries in the knee. Prevalance in patients who were sent for CTA was 12.08%. Routine CTA in patients with injuries in the knee is not recomended. The use of ankle brachial index may decrease the number of CTA done

Introduction. Knee dislocations, vascular injuries and floating knee injuries can be initially managed by a external fixator. Fixator design constructs include the AO pattern and the Diamond pattern. However, these traditional constructs do not adhere to basic principles of external fixation. The Manchester pattern knee-spanning external fixator is a new construct pattern, which uses beam loading and multiplanar fixation. There is no data on any construct pattern. This study compares the stability of these designs. Materials & Methods. Hoffman III (Stryker, USA) external fixation constructs were applied to articulated models of the lower limb, spanning the knee with a diamond pattern and a Manchester pattern. The stiffness was loaded both statically and cyclically with a Bose 3510 Electroforce mechanical testing jig (TA Instruments). A ramp to load test was performed initially and cyclical loading for measurement of stiffness over the test period. The results were analysed with a paired t-test and ANOVA. Results. The mean stiffness with the diamond pattern fixator was significantly less stiff than the Manchester pattern fixator – by a factor of 3 (40N/mm vs 115N/mm). Displacement increased in all patterns over simulated loading equating to six weeks. The diamond pattern demonstrated a 50%% increase in displacement over time. The Manchester pattern demonstrated only 20% increase in displacement over time. These are all statistically significant (p<0.01). Conclusions. The aim of an external fixator in knee dislocations and vascular injuries is to provide stability, prevent displacement and protect repairs. Vascular injuries often require fixation for several weeks to protect a repair. The Manchester pattern, applying the principles of external fixation, provides a stiffer construct and also confers greater stability over the time a fixator may be required. We commend this more informed design for the management of knee dislocations and vascular injuries

Abstract. Background. Traumatic knee dislocations are devastating injuries and there is no single best accepted treatment. Treatment needs to be customised to the patient taking into consideration injury to the knee; associated neurovascular and systemic injuries. Objective. This study looked at functional outcome of a single surgeon case series of patients who underwent surgical management of their knee dislocation. Methods. Seventy patients with knee dislocation were treated with multi-ligament reconstruction at a major trauma centre. Acute surgical repair and reconstruction with fracture fixation within 3 weeks was preferred unless the patient was too unstable (Injury severity score>16). PCL was primarily braced and reconstructed subsequently, if required. Outcome was collected prospectively using IKDC score, KOOS and Tegner score. Results. The mean age of the patients was 35yrs (17–74), 53 males and 17 females. 5 patients had CPN injury (7%), 3 had vascular injury (4.2%), 2 had combined CPN and vascular injury (2.8%). Acute surgical treatment was done in 48 patients while 10 had staged reconstruction. 22 patients had delayed reconstruction. The mean follow-up period was 4.8 years (1–12 yrs). According to the IKDC score 67% of the patients had near-normal knee function. The mean Tegner activity scale postoperatively was 4.5 (preinjury 6.5) and the mean KOOS score was 75.3. Four patients had stiffness and needed arthroscopic arthrolysis, two patients had a residual foot drop from the original injury and needed tendon transfer. Conclusion. Traumatic knee dislocation is a challenging problem but good outcomes can be achieved by surgical management

Introduction. Blunt trauma of the lower limb can lead to vascular injury causing devastating outcomes, including loss of limb and even loss of life. The primary aim of this study was to determine the limb salvage rate of patients sustaining such injuries when treated at Leeds General Infirmary (LGI) since becoming a Major Trauma Centre (MTC). Secondary aims included establishing the patient complications and outcomes. Materials and Methods. Retrospective analysis found that from 2013–18, 30 patients, comprising of 32 injured limbs, were treated for blunt trauma to the lower limb associated with vascular injury. Long-term functional outcomes were determined using postal and telephone questionnaires. Results. Twenty-four patients were male and 6 were female, their mean ages were 32 and 49 respectively. Of the 32 limbs, 27 (84%) were salvaged. Three limbs were deemed unsalvageable and underwent primary amputation; of the remaining 29 potentially salvageable limbs, 27 (93%) were saved. Eleven limbs had prophylactic fasciotomies, 3 limbs developed compartment syndrome – all successfully treated, and three contracted deep infections – one of which necessitated amputation. All but 1 patient survived their injuries and were discharged from hospital. Of the 15 questionnaire responses, self-reported limb function was understandably worse post-injury with patients experiencing mild pain on average. In addition, there was a long-standing psychological impact and the injuries altered many patients’ normal lives significantly, 10 experiencing financial difficulties and 6 having changed or lost jobs post-injury. Conclusions. Fortunately, 27 (84%) limbs were salvaged and nearly all patients survived these injuries when treated at an MTC. Whilst the number of complications was low, the future challenges these patients face are wide-ranging and significant

Multiligament knee injuries (MLKI) are rare and life-altering injuries that remain difficult to treat clinically due to a paucity of evidence guiding surgical management and timing. The purpose of this study was to compare injury specific functional outcomes following early versus delayed surgical reconstruction in MLKI patients to help inform timing decisions in clinical practice. A retrospective analysis of prospectively collected data from patients with MLKIs at a single academic level 1-trauma center was conducted. Patients were eligible for inclusion if they had an MLKI, underwent reconstructive surgery either prior to 6wks from injury or between 12weeks and 2 years from injury, and had at least 12months of post-surgical follow-up. Patients with a vascular injury, open injuries or associated fractures were excluded. Study participants were stratified into early (12 weeks - 2 years from injury). The primary outcome was patient reported, injury specific, quality of life in the form of the Multiligament Quality of Life questionnaire (MLQOL) and its four domains (Physical Impairment, Emotional Impairment, Activity Limitations and Societal Involvement). We secondarily analyzed differences in the need for manipulation under anesthesia, and reoperation rates, as well as radiographic Kellgren Lawrence (KL) arthritis grades, knee laxity grading and range of motion at the most recent follow-up. A total of 131 patients met our inclusion criteria, all having had surgery between 2006 and 2019. There were 75 patients in the early group and 56 in the delayed group. The mean time to surgery was 17.6 ± 8.0 days in the early group versus 279 ± 146.5 days in the delayed. Mean postoperative follow-up was 58 months. There were no significant differences between early and delayed groups with respect to age (34 vs. 32.8 years), sex (77% vs 63% male), BMI (28.3 vs 29.7 kg/m2), or injury mechanism (p>0.05). The early surgery group was found to include more patients with lateral sided injuries (n=49 [65%] vs. n=23 [41%]; p=0.012), a higher severity of Schenck Classification (p=0.024) as well as nerve injuries at initial presentation (n=35 [49%] vs n=8 [18%]; p0.05), when controlling for age, sex, Schenck classification, medial versus lateral injury, and nerve injury status. In terms of our secondary outcomes, we found that the early group underwent significantly more manipulations under anesthesia compare with the delayed group (n=24, [32%] vs n=8 [14%], p=0.024). We did not identify a significant difference in physical examination laxity grades, range of motion, KL grade or reoperation rates between groups (p>0.05). We found no difference in patient reported outcomes between those who underwent early versus delayed surgery following MLKI reconstruction. In our secondary outcomes, we found significantly more patients in the early surgery group required a manipulation under anesthesia following surgery, which may indicate a propensity for arthrofibrosis after early MLKI reconstruction

Patients with a vascular injury, open injuries or associated fractures were excluded. Study participants were stratified into early (<6wks from injury) and delayed surgical intervention (>12 weeks – 2 years from injury). The primary outcome was patient reported, injury specific, quality of life in the form of the Multiligament Quality of Life questionnaire (MLQOL) and its four domains (Physical Impairment, Emotional Impairment, Activity Limitations and Societal Involvement).

Multivariable linear regression analyses of the four domains of the MLQOL did not demonstrate an independent association with early versus delayed surgery status (p>0.05), when controlling for age, sex, Schenck classification, medial versus lateral injury, and nerve injury status. In terms of our secondary outcomes, we found that the early group underwent significantly more manipulations under anesthesia compare with the delayed group (n=24, [32%] vs n=8 [14%], p=0.024).

Abstract. Background. Fracture dislocation of the knee involves disruption of two or more knee ligaments with associated tibial plateau fracture. If these injuries are not evaluated swiftly, can result in a limb-threatening injury. The aim of this study is to look at the clinical outcomes of a single surgeon case series at a major trauma centre. Methods. Prospectively collected data was analysed for a 5-year period. Primary outcome measures used were International Knee Documented Committee(IKDC) score and Knee Injury & Osteoarthritis Outcome Score(KOOS). The secondary outcome measures include Tegner activity scale, knee range of movements & complications. Results. 23 patients were presented with the mean age was 37 years(17–74). 14% of patients sustained vascular injury & 19% had common peroneal nerve injury. Priority was given for early total repair/reconstruction with fracture fixation within 3 weeks where feasible (90% of patients), and if not, a staged approach was adopted. The mean IKDC score was 67 & KOOS was 73. The mean postoperative Tegner Activity Scale was 3.6 with mean flexion of 115(90–130). We observed some patterns of tibial plateau fractures are associated with similar patterns of ligamentous injuries. The anterio-medial rim fractures (52%) were associated with PCL, ACL & avulsion injuries of posterio-lateral corner structures. Most of the neurovascular injuries happened in this group. The other recognisable pattern was posterio-medial fractures, which were associated with ACL avulsion injury. Conclusion. To our knowledge, this is the first kind of study to report some fracture patterns that can be associated with particular ligamentous injuries

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


Introduction. The available scoring methods and outcome analysis methods in lower extremity skeletal trauma with vascular injuries are not always specific. Biochemical parameters like venous blood lactate, bicarbonate and serum CPK (at the time of admission and serial monitoring) were measured to assess whether they supplement clinical parameters in predicting limb salvageability in lower extremity skeletal trauma with vascular injuries. Materials and methods: 74 adult patients with long bone fracture of lower limb associated with vascular injury (open and closed) were included in the study group. Patients with significant head injury (who cannot provide informed consent) and those with mangled extremities (MESS score>8) were excluded. Methodology. Pre-operative requirement for fasciotomy was recorded. A vascular surgery consultation was obtained. CT angiography and DSA were performed if needed only. Venous blood samples from the injured limb were withdrawn for lactate and bicarbonate analysis. Serum CPK was estimated at the time of admission and repeated at 6, 12, 24, 48 and 72 hours after admission. A record was maintained about the type and duration of surgery, blood loss, type of anaesthesia used and fasciotomy in the post-operative period. Results. Of the 74 patients included in the study, 55 patients were taken up for a revascularization procedure, 13 patients for primary amputation and in remaining six patients, no vascular surgery was required. If the level of bicarbonate in the injured limb was less than 16.5 mmol/L, pH < 6.89 the probability of survival of the limb after a revascularization procedure is low and the injured limb will need an amputation eventually. Lactate levels and creatinine kinase were not of any predictive value regarding the outcome of the injured limb. Conclusion. Along with clinical signs, low levels of bicarbonate (<16.5 mmol/L), pH (<6.89), and high levels of pCO2, base deficit in the injured limb at the time of presentation were associated with the less favorable outcome-amputation

Purpose of study. Computerised Tomographic Angiography (CTA) is less invasive than conventional angiography. It is our perception that CTAs are being requested and performed too frequently at our institution without correct indications. We assessed the number of CTAs that were done, the percentage of vascular injuries sustained and whether correct indications were followed when requesting CTAs. Methodology. A review of records of the radiology department to determine the number of CTAs done for suspected extremity vascular injuries from January to December 2012. Inclusion criteria were CTAs performed during this period for suspected vascular injuries in fractures and dislocations and extremity gunshot wounds. A retrospective chart review was performed to determine the mechanism of injury, clinical picture (pulses, temperature, capillary refill and neurology), indications for and results of the CTA. Results. During this time 285 CTAs were performed of which 137 were suitable for analysis. One hundred and fifteen were males. The average age was 30.25 (range 14 to 86) years. Eighty six (62.77%) of the CTAs were normal. A further 4 patients showed no vascular injury, but with external compression of the vessels. The mechanism of injury was gunshot wounds in 58% of cases, motor vehicle accidents in 16.8% and pedestrian-motor vehicle accidents in 15%. 58.5% of cases with abnormal pulses had normal CTAs. Twenty one patients had normal pulses, but 5 of these had abnormal CTAs. Clinical assessment of peripheral pulse had a sensitivity of 81.5%, specificity of 34%, positive predictive value of 41.5% and negative predictive value of 76%. Conclusion. Thirty one (58.5%) of cases with abnormal pulses had normal CTAs, indicating that clinical examination is unreliable. Twenty one (15.3%) patients with normal pulses on clinical examination had CTAs performed. We believe CTAs are over-utilised due to availability rather than relying on serial clinical examination and non invasive testing. NO DISCLOSURES

Introduction:. Measurement of ankle brachial pressure index is an easy screening test to perform in patients presenting with an acute knee injury. According to Nicardi et al recognition of vascular injury is particularly challenging because vascular compromise may not be immediately associated with clinical signs of ischemia. The aim of the study is to correlate the values of ABPI measurements to CT angiograms and clinical outcome in high energy knee trauma. Materials and Methods:. We reviewed the records of patients admitted to our unit following high energy knee trauma during the period Nov 2012 to Dec 2013. The orthopaedic injuries sustained were 11 knee dislocations, 5 supracondylar femur fractures, 3 high energy tibia plateau fractures (Schatzker 5 and 6) and 4 gunshot injuries. From the records we recorded the nature of the orthopaedic injury, the ABPI, the CT angiogram and the clinical outcome. We excluded all patients with insufficient records and previous vasculopathy. After these exclusions, 23 patients were enrolled for the study. Analysis of the data involved calculating of basic descriptive statistics, including proportional and descriptive measures. T-tests (one-sample and independent) and chi-square tests of independence were employed to investigate the relationship between ABPI and CT angiogram and clinical outcomes. Throughout the statistical analysis cognisance is taken of the relative small sample, and relevant test adjustments made. Results:. A total of 5 of the 23 patients had a significant vascular injury that required vascular intervention. Three patients underwent vascular repair and orthopaedic fixation. One patient had an occult vascular injury and presented with a necrotic limb three days after admission. His delayed CT demonstrated arterial cut off. This patient later went on to have an amputation. The fifth patient presented 12 days post knee dislocation with reduced pulses but the leg was still viable. In these five patients the ABPI value ranged from 0.3 to 0.65. In the remainder the ABPI ranged from 0.91 to 1.4. These 18 patients had a CT angiogram with normal flow and no intimal tears. Conclusion:. In all the patients with vascular sequelae from high energy knee injuries and dislocation the initial ABPI measurement performed well as a screening test for vascular injuries. It can therefore be recommended as a practical investigation in the initial evaluation of knee injuries that has cost and time saving benefits

It is the prime responsibility of the treating surgeon to identify and treat the vascular injury along with the skeletal trauma. Limbs with combined Orthopaedic and Vascular injuries are traditionally admitted as an Orthopaedic emergency. In a 17 year period we treated 67 cases of vascular injuries (including 16 pseudo aneurysms) associated with fractures and dislocations or soft tissue injuries of the limbs. Three cases have been followed up for over 20 years. All patients were operated by Orthopaedic residents on duty with limited resources, without the help of vascular surgeons. We relied on clinical diagnosis and immediate exploration of the blood vessels rather than time consuming procedure of arteriography. Skeletal stabilisation was achieved by internal or external fixation. Vascular reconstruction involved end to end repair or vein grafting. Fasciotomy was performed in selected cases where the injury-revascularisation time was more than 6 hours. Post-operative care involved limb placement at body level, Sympathetic blockade for 48 hours, vasodilators, Lomodex, Mannitol, Aspirin and antibiotic therapy. Urine was monitored for smoky color indicating myoglobinuria. Though only 17 were repaired within six hours, limb viability with good function was obtained in 51 cases. Complications included 7 deaths, 6 amputations, 2 acute renal failures and delayed occlusion in one case

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. No knee-specific outcome measures have demonstrated reliability, validity or responsiveness in patients with multiligament knee injuries. Furthermore, the content validity of existing questionnaires has been challenged and remains unknown for patients with concomitant neurovascular injury. As a first step in developing a disease-specific outcome measure, the objective of this study was to identify items from existing knee questionnaires pertinent to patients with multiligament knee injuries using established a priori criteria. Method. Eighty-five consecutive patients from a level one trauma centre were mailed a questionnaire comprising 124 items from 11 knee-specific instruments. They rated the frequency and importance for each item on a five-point Likert scale. Criteria for item selection included a mean importance rating (MIR) ≥ 3.5 and frequency < 30% for the response never experienced. The World Health Organization International Classification of Functioning, Disability and Health (ICF) framework was used to support the content. Results. The average age of the 60/85 respondents (70.6%) was 34.7 years and most were male (n=45). Average time from injury was 845 days. Using the Schenck classification, 19 patients were KD I, two were KD II, 39 were KD IIIL or IIIM, and nine were KD IV. Nineteen had peroneal nerve injury and five had a vascular injury. Forty-four patients were treated surgically, six nonoperatively and 10 are pre-operative. Sixty-one of 124 questionnaire items met the a priori inclusion criteria. Based on the ICF, 22 of the retained items were physical impairments (PI), 15 items were emotional impairments (EI), 18 items were activity limitations (AL), and six items were participation restrictions (PR). The 10 items with the highest MIR included six EI, one PI and three PR. Twenty-four items (PI=6 EI=13, AL=2, PR=3) of the Anterior Cruciate Ligament Quality of Life Questionnaire (ACL-QoL) satisfied the a priori criteria and this instrument also endorsed the most items within the EI and PR constructs. The Knee Osteoarthritis and Injury Outcome Score (KOOS) had 21 items (PI=7, EI=2, AL=11, PR=1) which satisfied the a priori criteria and also had the most items within the PI and AL constructs. The International Knee Documentation Committee (IKDC) Subjective Knee Form had 12 items (EI=0, PI=3, AL=9, PR=0) meeting criteria while the remaining questionnaires contained 11 items with concepts redundant to above. Combining the ACL-QoL and KOOS resulted in representation of 41/61 of the retained items (PI=13, EI=13, AL=12, PR=3). No existing instrument includes content that may result from neurological or vascular injury. Conclusion. This work has identified over sixty pertinent items across the various ICF domains relevant to patients with multiligament knee injuries. The ACL-QoL and KOOS together address over two thirds of these items. Patient and clinician focus groups will be conducted to address missing content and to further refine the questionnaire items

Aim. Posttraumatic pelvic-osteomyelitis is one of the most serious complications after pelvic-fractures. The necessary extensive surgical debridement as part of interdisciplinary treatment is complicated by the possible persistence of pelvic instability. The aim of this study was to determine the outcome and outline the course of treatment after early posttraumatic pelvic bone infections due to type-C pelvic ring injuries. Method. In a retrospective cohort study (2005–2015) all patients with pelvic-osteomyelitis within six weeks of surgical stabilization of a type-C pelvic-fracture were assessed. Microbiological results, risk factors, course of treatment and functional long-term outcome using the Orlando-Pelvic-Score were analyzed. Results. A total of 18 patients (age 43.7 years; Body-Mass-Index 27.9 kg/m2; ASA-physical-status 1.8; Injury-Severity-Score 38) developed a pelvic-osteomyelitis within an average of 27 days after internal surgical stabilization of a type-C pelvic injury (AO-type C1: 10, C2: 4, C3: 4). Os pubis was affected in 7 and Os ilium in 11 cases. In addition to the pelvic-fracture, major vascular injuries occurred in 8, nerve injuries in 9, and intestinal and/or bladder ruptures in 11 cases. In 14 cases a mass transfusion was necessary. In addition to clinical signs of inflammation, (10 × redness, 12 × wound secretion, 6 × fistula) elevated levels of c-reactive-protein (7.7 mg/dl) and white-blood-cells (10.5/nl) were found. Bacterial cultures harvested during the initial surgical revision demonstrated mixed cultures in 17/18 cases, with an average of 3 different organisms isolated per case (61% intestinal bacteria). During the scheduled repetitive debridement a reduction of the initial mixed cultures into a single organism was observed. Overall 6.8 surgical interventions, including implant removal, were necessary until osteomyelitis was eradicated. In no cases was re-osteosynthesis performed. In 6/18 cases recurrence of infection occurred after an average of 5 months, followed by an additional repetitive debridement. An average 3-year-follow-up after the initial osteomyelitis-diagnosis demonstrated eradication of infection in 17/18 cases combined with an Orlando-Pelvic-Score of 21.9 points (best possible function: 40 points). Despite significant pelvic malalignment the ability to walk was achieved in all patients, with one exception due to a spinal cord injury. Conclusions. Despite no new surgical stabilization of the initial unstable pelvic injury, the early removal of implants combined with extensive debridement and antibiotic therapy led to sufficient long-term outcomes in patients with early posttraumatic pelvic-osteomyelitis. In particular, due to the severity of the initial injury and the complex interdisciplinary approach, early diagnosis of the osteomyelitis is essential

The primary objective of this study was to determine if paediatric proximal humerus fractures undergo significant displacement resulting in change in management. A retrospective analysis was performed on children who presented with proximal humeral fractures to our institution between 2009 and 2014. Patients were included if they were diagnosed with a fracture of the proximal humerus in the absence of an underlying bone cyst or pathological condition. Patients with open fractures, multiple fractures, neurologic, or vascular injuries were excluded. The primary endpoint was conversion to operative treatment after initial non-operative management. Secondary endpoints were a healed fracture with acceptable alignment at the final radiographic evaluation, as well as the number of follow-up radiographs obtained after the initiation of non-operative management. A decision to manage the fracture operatively at the initial presentation was made in 14 out of 239 patients. Of the 225 patients that were initially managed non-operatively, only 1 patient underwent subsequent surgical management. In this series, no non-unions, re-fractures, nor fracture-dislocations were identified. These data support that the majority of management decisions for paediatric proximal humeral fractures are made at the initial presentation. Once non-operative management is chosen, routine follow-up imaging rarely leads to any change in treatment

The major benefit of TKA with tourniquet is operating in a bloodless field. A possible secondary benefit is a better cement-bone interface for fixation. The disadvantages of tourniquet use for TKA include multiple risk factors both local and systemic: Nerve damage, Altered hemodynamics with limb exsanguinations (15–20% increase in circulatory volume) and reactive hyperemia with tourniquet release (10% increase in limb size increasing soft tissue tension and secondary pain), Delay in recovery of muscle function, Increased risk of DVT with direct trauma to vessel walls and increased levels of thrombin-antithrombin complexes, A 5.3x greater risk for large venous emboli propagation and transesophageal echogenic particles, Vascular injury with higher risk in atherosclerotic, calcified arteries, Increase in wound healing disturbances, Obese patients TKA with tourniquet show impaired endothelial function and more DVTs. Our initial experience with TKA without tourniquet was in high risk patients with previous DVT or PE, multiple scarring, or compromised cardiovascular status. We have used this method on all patients for the last 14 years. The protocol includes regional anesthesia, incision and approach made with 90-degree knee flexion, meticulous hemostasis, jet lavage and filtered carbon dioxide delivered to dry and prepare bone beds for cementation, application of topical tranexamic acid and routine closure. We have encountered no differences in blood loss or transfusion rates, cement penetration/ fixation, less postoperative pain, faster straight leg raise and knee flexion gains, and fewer wound healing disturbances. We recommend TKA sans tourniquet. Let it bleed!

Conflict in Afghanistan demonstrated predominantly lower extremity and pelvi-perineal trauma secondary to Improvised Explosive Devices (IEDs). Mortality due to pelvic fracture (PF) is usually due to exsanguination. This study group comprised 169 military patients who sustained a PF and lower limb injury. There were 102 survivors and 67 fatalities (39% mortality). Frequent fracture patterns were a widened symphysis (61%) and widening of the sacroiliac joints (SIJ) (60%). Fatality was 20.7% for undisplaced SIJs, 24% for unilateral SIJ widening and 64% fatality where both SIJs were disrupted, demonstrating an increase in fatality rate with pelvic trauma severity. A closed pubic symphysis was associated with a 19.7% mortality rate versus 46% when widened. Vascular injury was present in 67% of fatalities, versus 45% of survivors. Of PFs, 84% were associated with traumatic amputation (TA) of the lower limb. Pelvic fracture with traumatic lower limb amputation presents a high mortality. It is likely that the mechanism of TA and PF are related, and flail of the lower limb(s) is the current hypothesis. This study prompts further work on the biomechanics of the pelvic-lower limb complex, to ascertain the mechanism of fracture. This could lead to evidence-based preventative techniques to decrease fatalities

Total shoulder arthroplasty has been shown to be a very effective means of restoring function in all forms of arthritic shoulders. However, much as with any form of arthroplasty, problems and complications can and do occur. These include infection, nerve injury, anesthetic complications, peri-prosthetic fracture, instability and dislocation, nerve and vascular injury, loosening, loss of mobility, and contracture or stiffness, and implant related failures. Careful pre-operative planning, intra-operative technical execution, and post-operative rehabilitation all designed to meet the needs and demands of the specific patient can help identify potential sources of complications pre-operatively and avoid them post-operatively. Understanding the specific complexities of the type of arthritis being addressed, the strengths and weaknesses, limitations and need for adjustments to the local anatomy can help the surgeon execute the total shoulder arthroplasty with minimal likelihood for post-operative complications. Awareness of patient's own flora and application of appropriate antibiotic prophylaxis can help identify patients at risk for infection. Although it is impossible to fully eliminate the occurrence of complications, a majority can be avoided through attention to detail
