Aims. Compartment syndrome results from increased intra-compartmental pressure (ICP) causing local tissue ischaemia and cell death, but the systemic effects are not well described. We hypothesised that compartment syndrome would have a profound effect not only on the affected limb, but also on remote organs. Methods. Using a rat model of compartment syndrome, its systemic effects on the viability of hepatocytes and on inflammation and circulation were directly visualised using intravital video microscopy. Results. We found that hepatocellular injury was significantly higher in the compartment syndrome group (192 PI-labelled cells/10. -1 . mm. 3. , standard error of the mean (. sem. ) 51) compared with controls (30 PI-labelled cells/10. -1 . mm. 3. , . sem . 12, p < 0.01). The number of adherent venular white blood cells was significantly higher for the compartment syndrome group (5 leukocytes/30s/10 000 μm. 2. , . sem 1. ) than controls (0.2 leukocytes/30 s/10 000 μm. 2. , . sem . 0.2, p < 0.01). Volumetric blood flow was not significantly different between the two groups, although there was an increase in the heterogeneity of perfusion. Conclusions. Compartment syndrome can be accompanied by severe systemic inflammation and end organ damage. This study provides evidence of the relationship between compartment syndrome in a limb and systemic inflammation and dysfunction in a remote organ.

Compartment syndrome, a devastating consequence of limb trauma, is characterised by severe tissue injury and microvascular perfusion deficits. We hypothesised that leucopenia might provide significant protection against microvascular dysfunction and preserve tissue viability. Using our clinically relevant rat model of compartment syndrome, microvascular perfusion and tissue injury were directly visualised by intravital video microscopy in leucopenic animals. We found that while the tissue perfusion was similar in both groups (38.8% (standard error of the mean (. sem). 7.1). , 36.4. % (. sem. 5.7), 32.0% (. sem. 1.7), and 30.5% (. sem. 5.35) continuously-perfused capillaries at 45, 90, 120 and 180 minutes compartment syndrome, respectively versus 39.2% (. sem. 8.6), 43.5% (. sem. 8.5). , . 36.6% (. sem. 1.4) and 50.8% (. sem. 4.8) at 45, 90, 120 and 180 minutes compartment syndrome, respectively in leucopenia), compartment syndrome-associated muscle injury was significantly decreased in leucopenic animals (7.0% (. sem. 2.0), 7.0%, (. sem. 1.0), 9.0% (. sem. 1.0) and 5.0% (. sem. 2.0) at 45, 90, 120 and 180 minutes of compartment syndrome, respectively in leucopenia group versus 18.0% (. sem. 4.0), 23.0% (. sem. 4.0), 32.0% (. sem. 7.0), and 20.0% (. sem. 5.0) at 45, 90, 120 and 180 minutes of compartment syndrome in control, p = 0.0005). This study demonstrates that the inflammatory process should be considered central to the understanding of the pathogenesis of cellular injury in compartment syndrome.

We have analysed associated factors in 164 patients with acute compartment syndrome whom we treated over an eight-year period. In 69% there was an associated fracture, about half of which were of the tibial shaft. Most patients were men, usually under 35 years of age. Acute compartment syndrome of the forearm, with associated fracture of the distal end of the radius, was again seen most commonly in young men. Injury to soft tissues, without fracture, was the second most common cause of the syndrome and one-tenth of the patients had a bleeding disorder or were taking anticoagulant drugs. We found that young patients, especially men, were at risk of acute compartment syndrome after injury. When treating such injured patients, the diagnosis should be made early, utilising measurements of tissue pressure

The aim of this study was to document our experience of acute forearm compartment syndrome, and to determine the risk factors for requiring split skin grafting (SSG) and developing complications post fasciotomy. We identified from our trauma database all patients who underwent fasciotomy for an acute forearm compartment syndrome over a 22-year period. Diagnosis was made using clinical signs and/or compartment pressure monitoring. Demographic data, aetiology, management, wound closure, complications and subsequent surgeries were recorded. Outcome measures were the use of SSG and the development of complications following forearm fasciotomy. 90 patients were identified with a mean age of 33 yrs (range, 13–81 yrs) and a significant male predominance (n=82, p<0.001). A fracture of one or both of the forearm bones was seen in 62 (69%) patients, with soft tissue injuries causative in 28 (31%). The median time to fasciotomy was 12hrs (2–72). Delayed wound closure was achieved in 38 (42%) patients, with 52 (58%) undergoing SSG. Risk factors for requiring a SSG were younger age and a crush injury (both p<0.05). Complications occurred in 29 (32%) patients at mean follow-up of 11 (3–60) months. Risk factors for developing complications were a delay in fasciotomy of >6 hrs (p=0.018), with pre-operative motor symptoms approaching significance (p=0.068). Forearm compartment syndrome requiring fasciotomy predominantly affects males and can occur following either a fracture or soft tissue injury. Age is an important predictor of undergoing SSG for wound closure. Complications occur in a third of patients and are associated with an increasing delay in the time to fasciotomy

Aim. To review current military orthopaedic experience and establish if there exists a consensus of opinion in how and if to perform fasciotomy of the foot and to guide other clinicians. Method. A questionnaire was sent to 10 DMS orthopaedic consultants to identify their experience with foot compartment syndrome and performing fasciotomies. Results. 50% had performed a foot fasciotomy (average 2, range 1-6) over an average of 6.2 years as consultant and an average of 7.3 months deployed. Most commonly two dorsal and a medial incision were used to decompress the foot, while one advocated not decompressing and accepting the contractures, a view consistent with some civilian literature. Discussion. The debate surrounding decompression stems from the rarity of the condition, the lack of consensus regarding the anatomy of the foot compartments and whether to accept the inevitable contractures by not decompressing. Given that foot compartment syndrome may not be seen during civilian training, then there is a requirement for guidance for the deploying military surgeon. Conclusion. DMS clinicians need to remain vigilant to compartment syndrome of the foot and especially in cases of crush or blast injury or of multiple fractures. If diagnosed or even if an impending compartment syndrome is suspected then the foot should be decompressed and the deployed orthopaedic surgeon should be capable of performing it

We reviewed 25 patients with tibial diaphyseal fractures which had been complicated by an acute compartment syndrome. Thirteen had undergone continuous monitoring of the compartment pressure and the other 12 had not. The average delay from injury to fasciotomy in the monitored group was 16 hours and in the non-monitored group 32 hours (p < 0.05). Of the 12 surviving patients in the monitored group, none had any sequelae of acute compartment syndrome at final review at an average of 10.5 months. Of the 11 surviving patients in the non-monitored group, ten had definite sequelae with muscle weakness and contractures (p < 0.01). There was also a significant delay in tibial union in the non-monitored group (p < 0.05). We recommend that, when equipment is available, all patients with tibial fractures should have continuous compartment monitoring to minimise the incidence of acute compartment syndrome

Whilst emergency fasciotomy for acute compartment syndrome (ACS) of the leg is limb and potentially lifesaving, there remains a perception that such surgery may result in excessive morbidity, which may deter surgeons in providing expeditious care. There are limited long-term studies reporting on the morbidity associated with fasciotomy. A total of 559 patients with a tibial diaphyseal fracture were managed at our centre over a 7-year period (2009–2016). Of these patients, 41 (7.3%) underwent fasciotomies for the treatment of ACS. A matched cohort of 185 patients who did not develop ACS were used as controls. The primary short-term outcome measure was the development of any complication. The primary long-term outcome measure was the patient reported EQ-5D. There was no significant difference between fasciotomy and non-fasciotomy groups in the overall rate of infection (17% vs 9.2% respectively; p=0.138), deep infection (4.9% vs 3.8%; p=0.668) or non-union (4.9% vs 7.0%; p=1.000). There were 11 (26.8%) patients who required skin grafting of fasciotomy wounds. There were 206 patients (21 ACS) with long-term outcome data at a mean of 5 years (1–9). There was no significant difference between groups in terms of the EQ-5D (p=0.81), Oxford Knee Score (p=0.239) or the Manchester-Oxford Foot Questionnaire (p=0.629). Patient satisfaction on a linear analogue scale was reduced in patients who developed ACS (77 vs 88; p=0.039). These data suggest that when managed with urgent decompressive fasciotomies, ACS does not appear to have a significant impact on the long-term patient reported outcome, although overall patient satisfaction is reduced

Failure to treat acute compartment syndrome (ACS) early leads to significant morbidity. Current practice depends on using clinical signs and intracompartmental pressure (ICP) monitoring to diagnose the syndrome but there is still debate regarding their accuracy and interpretation. Patients admitted with injuries at risk of ACS underwent intramuscular (IM) pH and ICP monitoring combined with regular clinical assessment. Fasciotomies were performed on those with clinical and/or pressure based evidence of ACS. All patients were subsequently assessed for evidence of a missed ACS at at 6 & 12 months. Of the 62 patients, 51 completed the protocol and were included in the analysis. They were divided into 2 groups: those who had ACS, either initially (fasciotomies; 13), or diagnosed at follow up (no fasciotomies; 7), and those with no evidence of ACS (31). The sensitivity and specificity for the worst values for each variable were calculated and receiver operator characteristic (ROC) curves generated. The area under the curve for pH was 0.92, 0.73 for absolute pressure and 0.59 for delta pressure. To achieve a sensitivity of 95%, an absolute pressure of >30mmHg was 30% specific, a delta pressure of <33mmHg was 27%, while IM pH of 6.38 was 80% specific. This study highlights the issues concerning current diagnostic methods for ACS. By comparison, IM pH radically out performed both the highest ICP and the lowest delta pressure, identifying patients early and accurately

Background. Overlooked compartment syndrome represents a devastating complication for the patient. Invasive compartment pressure measurement continues to be the gold standard. However, repeated measurements in uncertain cases may be difficult to achieve. We developed a new, noninvasive method to assess tissue firmness by pressure related ultrasound. Methods. Decreased tissue elasticity by means of rising compartment pressures was mimicked by infusion of saline directly into the anterior tibial compartment of 6 human specimens post mortem. A pressure transducer (Codman) monitored the pressure of the anterior tibial compartment. A second transducer was located in a saline filled ultrasound probe head to allow a simultaneous recording of the probe pressure provoked by the user. The ultrasound images were generated at 5 and 100mmHg probe pressures to detect the tissue deformity by B-mode ultrasound. The fascial displacement was measured before and after compression (d). Subsequently, increments of 5mmHg pressure increases were used to generate a standard curve (0–80mmHg), thus mimicking rising compartment pressures. The intra-observer reliability was tested using 10 subsequent measurements. A correlation was determined between d and the simulated intacompartmental pressure (ICP) in the compartment. The Pearson correlation coefficient (r) was calculated. The reliability determined by the kappa value and a regression analysis was performed. Results. With rising compartmental pressure, a concordant consistent correlation between d and ICP occurred. The Pearson coefficient was significant at r=0.979 and the intra-observer value kappa (k) showed a statistically good reliability (k10=0.73 and k70=0.79). Within a pressure ranging from 5–35mmHg there was an almost linear behavior, with decreasing elasticity and tissue movement in case of raising ICP. Conclusions. Pressure related ultrasound emphasized as a reliable tool to determine the correlation between the measured compartmental displacement and the raising intracompartmental pressures. This may help to improve the clinical assessment of the compartment elasticity by the physician. Further studies are required to investigate whether the good correlation also applies for the clinical scenario. However, this new method may be useful to monitor trends in the compartment pressures and may help to avoid delayed decision of fasciotomy

There is much debate regarding the use of continuous-compartment-pressure-monitoring (CCM) in the diagnosis of acute compartment syndrome (ACS). We retrospectively reviewed the management of all patients (aged 15 and over) who were admitted with a fracture of the tibial diaphysis, across 3 centres, during 2013–2015. Patient demographics, pre-existing medical problems, initial treatment, subsequent complications, methods of compartment monitoring, and follow-up were all included in the data collection. We separated patients into monitored (MG) and non-monitored groups (NMG), and compared the outcomes of their treatment. Data analysis was performed using SPSS and statistical significance was set as p < 0.05. 287 patients were included in this study (116 NMG vs. 171 MG). There were no significant differences observed in age, sex, previous medical problems, length of stay, AO classification of fracture and post-operative complications between the groups. 21 patients were suspected to have developed ACS (n=8 NMG 6.9percnt;, n=13 MG 7.6percnt;) and were treated with acute decompression fasciotomies. The average time from admission to fasciotomy was 20.3 hours (21.25hrs NMG, 19.5hrs MG p=0.448). There was no significant difference in the average length of hospital stay and documentation of complications at follow up between the 2 groups. There were no reported cases of soft tissue infections associated with the use of CCM. This study illustrates that CCM does not increase the rate of fasciotomies in this patient group, or reduce the time to fasciotomy significantly. There was no evidence to suggest that use of CCM is associated with superficial or deep infection

CECS is an exercised induced condition that causes pain, typically in the lower limbs, and is relieved by rest. It is often seen in military personnel significantly restricting their duties. Conservative treatment is rarely successful and patients often require surgical decompression by fasciotomy or fasciectomy.

All IMP (intramuscular pressure) tests (n=286) carried out between December 2007 and October 2010 on patients with suspected CECS in the anterior compartment of the lower leg were reviewed. The treatment and outcomes of those referred for surgery were analysed. Pre- and post-surgery military medical grading for leg function was extracted from the medical records system. Independent t-tests compared differences between patients that had surgery or did not. The Wilcoxon signed-rank test compared grades before and after surgery.

According to the diagnostic criterion, 80% of patients undergoing IMP testing had CECS. Of these, 179 (68%) patients underwent surgery, 17 (9%) of these were for recurrent symptoms. Almost all decompressions were bilateral (95%). The majority of operations (121) were fasciectomies of the anterior compartment only and were performed by 2 surgeons. The remaining operations (58) were performed by 6 surgeons and were fasciotomies of both anterior and lateral compartments. The mean time from testing to surgery was 24 (median 11) weeks. There were 23 (13%) complications other than recurrence including 16 wound infections, 6 seromas and 1 haematoma. Pre- and post-surgery grading was available for 67% of patients. These patients had significantly better leg function after surgery (Z=−3.67, p<0.001). Of these, 47% improved, 38% showed no improvement and 15% had a poorer outcome had. Those who had a fasciectomy were significantly more likely to improve than those who had a fasciotomy (p=0.023, rho=−1.96).

Our results demonstrate that patients generally improve lower limb function following surgical decompression. However, 53% showed no improvement or deteriorated in their medical grading. In addition, there is a high diagnosis rate for CECS following IMP measurement. This may reflect the poor validity of the diagnostic criterion or this could be due to good clinical selection for testing. Furthermore, fasciectomy shows a greater correlation with improved outcome than fasciotomy. There is a need to develop more accurate diagnostic criteria and to evaluate the benefits of standardising surgical technique.

We made a prospective study of 116 patients with tibial diaphyseal fractures who had continuous monitoring of anterior compartment pressure for 24 hours. Three patients had acute compartment syndrome (2.6%). In the first 12 hours of monitoring, 53 patients had absolute pressures over 30 mmHg and 30 had pressures over 40 mmHg, with four higher than 50 mmHg. Only one patient had a differential pressure (diastolic minus compartment pressure) of less than 30 mmHg; he had a fasciotomy. In the second 12-hour period 28 patients had absolute pressures over 30 mmHg and seven over 40 mmHg. Only two had differential pressures of less than 30 mmHg; they had fasciotomies. None of our 116 patients had any sequelae of the compartment syndrome at their latest review at least six months after injury. A threshold for decompression of 30 mmHg would have indicated that 50 patients (43%) would have required fasciotomy, and at a 40 mmHg threshold 27 (23%) would have been considered for an unnecessary fasciotomy. In our series, the use of a differential pressure of 30 mmHg as a threshold for fasciotomy led to no missed cases of acute compartment syndrome. We recommended that decompression should be performed if the differential pressure level drops to under 30 mmHg

Background. To improve patient pathways we have, in selected patients, begun to acutely apply circular (rather than temporary monolateral) fixators with simultaneous or subsequent soft tissue closure. We present early results. Methods. Adult patients treated using an Ilizarov frame prior to soft tissue management were identified from our Ilizarov database. This data was supplemented by medical record review. Results. 26 cases were identified (22 open fractures (11 IIIA, 11 IIIB), 1 compartment syndrome and 3 infected salvage). All IIIA injuries were closed acutely alongside frame application. In IIIB fractures, 3 were closed following acute shortening, 1 required a local flap and 7 free tissue transfer. Soft tissue reconstruction was simultaneous to frame application in 5 patients, the remainder within 72 hours. In salvage cases, 2 required free and one a local muscle flap, all after frame application. There were no soft tissue cover failures. One patient underwent evacuation of a flap haematoma, there were no other unexpected returns to theatre for soft tissue problems. No patients required adjustment of frame components to allow soft tissue access. Conclusion. This approach appears to simplify treatment, reducing length of stay. We are collecting a matched patient series treated by traditional pathways for comparison

Background. The optimal treatment of segmental tibial fractures (STF) is controversial. Intramedullary nailing (IMN) and external fixation (EF) have unique benefits and complications. Aim. To compare outcomes for AO/OTA 42C2 and 42C3 fractures treated using IMN with those treated using EF in a University Teaching Hospital. Methods. Retrospective case note and radiograph review of 31 segmental tibial fractures treated between 2010 and 2017. Results. There were 17 42C2 and 14 42C3 fractures. 17 patients underwent IMN and 14 EF, and were matched for age and gender. 9 fractures in each group were open. Median time to radiological union was 7 months for IMN and 8 months for EF. Revision surgery was needed for 4 IMN patients and 3 EF patients. The mean number of unplanned procedures was 1.46 for IMN and 1.1 for EF (p=0.69). Length of stay was 15.5 days for IMN and 16.2 days for EF (p=0.9). There was one compartment syndrome in each group and 2 cases of deep infection in the IMN group. There was no significant difference in coronal and sagittal plane alignment. Conclusions. Notwithstanding the small numbers and the retrospective design, the results show that the results of IMN may be equivalent to EF. Modern techniques using suprapatellar entry and blocking screws, combined with early plastic surgical coverage in open injuries are likely to have improved outcomes. Implications. Modern IM nailing techniques have produced similar clinical and radiological outcomes to that achieved by external fixation in this series

Scar tissue formation secondary to acute muscle injury, surgical wounding and compartment syndrome can result in significant functional impairment and predispose to further injury. The source of fibroblasts, and the molecular mechanisms driving their activation and persistence in skeletal muscle fibrosis are not known. We hypothesized that cells expressing PDGFRβ become fibroblasts in response to injury and that targeting αv integrins in these cells reduces skeletal muscle fibrosis. We used double-fluorescent reporter mice to demonstrate that cells expressing PDGFRβ become activated myofibroblasts in response to cardiotoxin (CTX) induced skeletal muscle injury. Following injury, PDGFRβ+ cells moved from perivascular locations into the interstitium in a distribution characteristic of fibroblasts, and showed marked induction of fibroblastic genes including αSMA and collagen1 (all p<0.0001). To confirm that αv integrins present on PDGFRβ cells critically regulate skeletal muscle fibrosis we used Itgavflox/flox;PDGFRβ-Cre mice (transgenic mice in which αv integrins are ‘knocked-down’ in PDGFRβ+ cells). These mice were significantly protected from CTX induced fibrosis (p<0.01). To demonstrate potential clinical utility of targeting αv integrins, we used a small molecule inhibitor of αv integrins (CWHM12). Treatment with CWHM12 significantly reduced fibrosis when delivered from the time of injury (p<0.01) and when delivered after the fibrotic response had become established (p<0.01). We have identified a core pathway regulating fibrosis in skeletal muscle. Pharmacologic inhibition of αv integrins has potential clinical utility in the treatment and prevention of skeletal muscle fibrosis

We aimed to analyse complication rates following medial opening-wedge high tibial osteotomy (OWHTO) for knee OA. A regional retrospective cohort study of all patients who underwent HTO for isolated medial compartment knee OA from 2003–2013. 115 OWHTO were performed. Mean age = 47 (95%CI 46–48). Mean BMI = 29.1 (95%CI 28.1–30.1). Implants used: 72% (n=83) Tomofix, 21% (n=24) Puddu plate, 7% (n=8) Orthofix Grafts used: 30% (n=35) autologous, 35% (n=40) artificial and 35% (n=40) no graft. 25% (n=29) of patients suffered 36 complications. Complications included minor wound infection 9.6%, major wound infection 3.5%, metalwork irritation necessitating plate removal 7%, non-union requiring revision 4.3%, vascular injury 1.7%, compartment syndrome 0.9%, and other minor complications 4%. Apparent higher rates of non-union occurred with the Puddu plate (8.3%) relative to Tomofix (3.6%) but was not statistically significant. No other significant differences existed in complication rates relative to implant type, bone graft used, patient age or BMI. Serious complications following HTO appear rare. The Tomofix has an apparent lower rate of non-union compared to older implants but greater numbers are required to determine significance. There is no significant difference in union rate relative to whether autologous graft, artificial graft or no graft is used

We made a prospective study of 208 patients with tibial fractures treated by reamed intramedullary nailing. Of these, 11 (5.3%) developed dysfunction of the peroneal nerve with no evidence of a compartment syndrome. The patients with this complication were significantly younger (mean age 25.6 years) and most had closed fractures of the forced-varus type with relatively minor soft-tissue damage. The fibula was intact in three, fractured in the distal or middle third in seven, with only one fracture in the proximal third. Eight of the 11 patients showed a ‘dropped hallux’ syndrome, with weakness of extensor hallucis longus and numbness in the first web space, but no clinical involvement of extensor digitorum longus or tibialis anterior. This was confirmed by nerve-conduction studies in three of the eight patients. There was good recovery of muscle function within three to four months in all cases, but after one year three patients still had some residual tightness of extensor hallucis longus, and two some numbness in the first web space. No patient required further treatment

Aims

The primary aim of this study was to identify independent predictors associated with nonunion and delayed union of tibial diaphyseal fractures treated with intramedullary nailing. The secondary aim was to assess the Radiological Union Scale for Tibial fractures (RUST) score as an early predictor of tibial fracture nonunion.

Methods

A consecutive series of 647 patients who underwent intramedullary nailing for tibial diaphyseal fractures were identified from a trauma database. Demographic data, comorbidities, smoking status, alcohol consumption, use of non-steroidal anti-inflammatory drugs (NSAIDs), and steroid use were documented. Details regarding mechanism of injury, fracture classification, complications, and further surgery were recorded. Nonunion was defined as the requirement for revision surgery to achieve union. Delayed union was defined as a RUST score < 10 at six months postoperatively.

Aims

The study objective was to prospectively assess clinical outcomes for a pilot cohort of tibial shaft fractures treated with a new tibial nailing system that produces controlled axial interfragmentary micromotion. The hypothesis was that axial micromotion enhances fracture healing compared to static interlocking.

Methods

Patients were treated in a single level I trauma centre over a 2.5-year period. Group allocation was not randomized; both the micromotion nail and standard-of-care static locking nails (control group) were commercially available and selected at the discretion of the treating surgeons. Injury risk levels were quantified using the Nonunion Risk Determination (NURD) score. Radiological healing was assessed until 24 weeks or clinical union. Low-dose CT scans were acquired at 12 weeks and virtual mechanical testing was performed to objectively assess structural bone healing.
