Introduction. Compartment syndrome can be a life changing consequence of injury to a limb. If not diagnosed and treated early it can lead to permanent disability. Neurovascular observations done on the ward by nursing staff, are often our early warning system to those developing compartment syndrome. But are these adequate for detecting the early signs of compartment syndrome? Our aim was to compare the quality and variability of charts across the UK major trauma network. Materials & Methods. All major trauma centres in England and Scotland were invited to supply a copy of the neurovascular chart routinely used. We assessed how such charts record relevant information. Specific primary data points included were pain scores, analgesia requirements, pain on passive stretch and decreased sensation in the first web space specifically. As secondary objectives, we assessed how late signs were recorded, whether clear instructions were included, quantitative scores and the use of regional blocks recorded. Results. A response rate of 46% was achieved. Of the charts reviewed, 25% documented pain scores or pain on passive movement. Pain on movement and analgesia requirements were documented in 33% and 8% respectively. Specific sensation within the 1. st. webspace was recorded in 16%. No charts recorded use of regional block. All charts recorded global sensation, movement (unspecified), pulse and colour whilst 66% documented capillary refill and 83% temperature. Instructions were included in 41% of charts. Conclusions. In 2016, the BOA supported publication of an observation chart for this purpose however, it is not widely used. In our study, late signs of compartment syndrome were generally well recorded. However, documentation of early signs and regional blocks was poor. This may lead to delays in diagnosis with significant clinical and medicolegal consequences. Standardisation of documentation by updating and promoting the use of the pre-existing chart would ensure highest quality care across the network

Acute Compartment Syndrome (ACS) is an orthopaedic emergency that can develop after a wide array of etiologies. In this pilot study the MY01 device was used to assess its ease of use and its ability to continuously reflect the intracompartmental pressure (ICP) and transmit this data to a mobile device in real time. This preliminary data is from the lead site which is presently expanding data collection to five other sites as part of a multi-center study. Patients with long bone trauma of the lower or upper extremity posing a possibility of developing compartment syndrome were enrolled in the study. Informed consent was obtained from the patients. A Health Canada licensed continuous compartmental pressure monitor (MY01) was used to measure ICP. The device was inserted in the compartment that was deemed most likely to develop ACS and ICP was continuously measured for up to 18 hours. Fractures were classified according to the AO/OTA classification. Patient clinical signs and pain levels were recorded by healthcare staff during routine in-patient monitoring and were compared to the ICP from the device. Important treatment information was pulled from the patient's chart to help correlate all of the patient's data and symptoms. The study period was conducted from November 2020 through December 2021. Twenty-six patients were enrolled. There were 17 males, and nine females. The mean age was 38 years (range, 17–76). Seventeen patients received the device post-operatively and nine received it pre-operatively. Preliminary results show that post-operative ICPs tend to be significantly higher than pre-operative ICPs but tend to trend downwards very quickly. The trend in this measurement appears to be more significant than absolute numbers which is a real change from the previous literature. One patient pre-operatively illustrated a steep trend upwards with minimal clinical symptoms but required compartment release at the time of surgery that exhibited no muscle necrosis. The trend in this patient was very steep and, as predicted, predated the clinical findings of compartment syndrome. This trend allows an early warning signal of the absolute pressure, to come, in the compartment that is being assessed by the device. Preliminary results suggest that this device is reliable and relatively easy to use within our institutions. In addition it suggests that intracompartmental pressures can be higher immediately post-op but lower rapidly when the patient does not develop ACS. These results are in line with current literature of the difference between pre and post-operative baselines and thresholds of ICP, but are much more striking, as continuous measurements have not been part of the data set in most of past studies. Further elucidation of the pressure thresholds and profiles are currently being studied in the ongoing larger multicenter study and will add to our understanding of the critical values. This data, plus the added value of continuous trends in the pressure, upwards or downwards, will aid in preventing muscle necrosis during our management of these difficult long bone fractures

Purpose. Compartment syndrome is a limb threatening condition. Prior research has been limited by an inability to assess functional and histologic changes in muscle over time. This study was designed to assess and quantify functional deficits and histologic changes following acute compartment syndrome of the lower limb in a novel rat model. Method. Twenty-three male Wistar rats were trained to perform an incentive-based standard task on an optical gait tracking system. Animals were then randomized to three groups: Control (n=4), Sham (n=4) and Compartment Syndrome (CS, n=15). Control and sham animals had no elevation of intracompartmental pressure, while CS animals had elevated intracompartmental pressure to 30mmHg for 180 minutes in the anterior compartment of the left hind limb using a saline infusion technique. Following intervention, gait analysis was performed at 2hrs, 24hrs, 48hrs, 72hrs and 7days following injury. Several parameters for the injured hind limb were analyzed including: print area, print intensity, maximum contact timing, duty cycle and stance phase time. A 2-way ANOVA with Bonferroni post-hoc analysis was performed. The EDL muscle was harvested (n=17), fixed in formalin and prepared with an H&E stain. Mid-muscle sections were analyzed by a blinded senior pathologist for cell infiltration, necrosis and regeneration. Results. Function Changes: Mean print intensity was 96.5518.7 at 48hrs for CS animals, compared to 145.538.2 in control animals and 144.9612.71 in sham animals (p<0.001). At the 2hrs, 24hrs, and 48hrs time intervals post injury the CS animals showed significant decreases in print width (p<0.001), maximum contact (p<0.001), mean print intensity (p<0.001) and stance phase (p<0.01). There were no significant differences between baseline and 72hr results for any gait parameter (p>0.05). Histologic Changes: Cellular infiltration was noted at 24hrs, peaked at 48hrs and was still present at 7 days to a lesser degree. Necrosis began as early as 24hrs post injury and also peaked by 48hrs and returned to baseline levels by 7days. Minor regenerative changes were identified as early as 24hrs however the majority of changes were identified at 7 days post-injury. Conclusion. Developing and evaluating animal models for the study of compartment syndrome is essential for better understanding the condition and testing new treatment modalities. Gait analysis was a reproducible means of assessing function after compartment syndrome. Animals demonstrated an antalgic gait pattern demonstrated by decreased stance phase, decreased print intensity, and increased print width, with recovery demonstrated by 72hrs post-injury. Defining the histologic changes such as necrosis, cellular infiltration and regeneration associated with compartment syndrome has allowed us to further understand the evolving pathology of compartment syndrome over time. This study facilitates the evaluation of functional and histologic testing for the evaluation of new therapeutic interventions

To assess outcomes following a radical approach to cases of compartment syndrome in which a significant degree of muscle necrosis is found, 4 paediatric and adolescent patients with a delayed diagnosis of compartment syndrome in which muscle necrosis in single or multiple compartments were treated by radical debridement of necrotic tissue and reconstruction of the anterior compartment through transfer of peroneus brevis to extensor digitorum and hallucis longus tendons. Where suitable, a free vascularised and innervated gracilis muscle transfer to the tibialis anterior tendon stump was carried out with anastomosis of the nerve to gracilis to the deep peroneal nerve. Free gracilis muscle transfer was functional in one of the two patients whilst peroneus brevis transfer to extensor digitorum and hallucis tendons was functional in all three patients. In one patient, radical debridement resulted in loss of the entire anterior compartment requiring permanent ankle foot orthosis. All others had recovery of protective foot sensation and at minimum follow-up of 12 months were walking unaided. Infection was not seen in any patient. Prompt fasciotomy, debridement and reconstruction for late diagnosis of compartment syndrome proved limb-saving in our patients

The threshold for decompression in acute compartment syndrome is quoted as a pressure difference between the compartment and diastolic blood pressure of less than 30mmHg. This study reports the findings of continuous compartment pressure monitoring in children who underwent tibial osteotomies. In this prospective observational study, twenty seven children who underwent tibial osteotomies had anterior compartment pressures monitored using a transducer-tipped probe for a minimum of 72 hours following surgery. Pressure data were collected hourly together with evidence of clinical signs, symptoms and patterns of analgesic use. Patients were also reviewed for late sequelae of compartment syndrome. One case of compartment syndrome were encountered. Pressure differences (diastolic BP - compartment pressure) were found to vary widely, with many children exceeding the threshold for decompression but without manifesting other signs of compartment syndrome. Fasciotomies were not performed in view of the conflicting evidence and subsequent review confirmed the absence of late sequelae. In these children, low diastolic blood pressures were a common but normal feature. The prevalence of compartment syndrome was 3.7% (1/27). The positive predictive value of using the adult threshold was 7.1%; the negative predictive value was 100%. We conclude that the threshold for decompression as applied to adults is unsuitable for use in children inasmuch as a positive result would lead to a correct diagnosis in only 7.1% of children. A negative test is more useful in correctly excluding compartment syndrome in 100% of the children studied

Aims. Compartment syndrome (CS) is a well-recognised, serious complication of long bone fractures. The association between CS and tibial shaft fractures is well documented in adult patients and in children with open or high velocity trauma. There is, however, little literature on the risk of developing CS in children with closed tibial fractures. In a number of units these children are routinely admitted for elevation and monitoring for CS. We audited our experience of managing paediatric tibial fractures to ascertain whether it may be safe to discharge a sub-group of these children. Methods. We audited all children up to the age of 12 years admitted to our hospital over a 5 year period. We reviewed radiographs and clinical notes to determine fracture pattern, modality of treatment, and complications. Results. We audited 159 tibial fractures. The mean age was 5.8 years (1–12 years), 95 boys, 64 girls. 105 (66%) closed fractures were conservatively managed: 87 of these were diaphyseal and 20 involved both tibia and fibula. Of the conservatively managed fractures, 89 (85%) were minimally displaced (< 5 degrees varus/valgus/anterior angulation, < 5 degrees rotation, < 5mm shortening, no posterior angulation). In the conservatively managed group there were 3 cases of angulation in cast, managed with wedging. There were no other complications and no cases of compartment syndrome. Conclusion. Of the 105 closed tibial fractures we managed conservatively, most were minimally displaced, diaphyseal, tibia-only fractures. No patient developed compartment syndrome. Based on our experience we suggest that children with closed, minimally displaced tibial fractures do not require admission for monitoring of CS and may go home in a plaster-slab with early fracture clinic follow-up providing suitable supervision is in place, pain is controlled, and they are able to mobilise safely

Purpose. Pediatric tibial shaft fractures (TSF) account for 15% of long bone fractures in children. Compartment syndrome (CS) is difficult to diagnose in children, often leading to disastrous outcomes. This study investigated the incidence of CS in TSF and its associated risk factors. Method. A detailed five-year retrospective chart review of TSF treated at a major pediatric hospital. CS was diagnosed clinically or by intra-compartment pressure. Multivariate logistic regression analysis tested age, gender, mechanism of injury, time to surgery, fracture type, and treatment intervention as possible risk factors for CS. Results. There were 216 TSF in 212 children (160 males, 52 females; mean age 13.6 years, range eight-18 years). One hundred and thirty-two (61%) fractures were treated with closed reduction and casting, 36 with external fixation, 21 with flexible intramedullary nails, and 27 with locked intramedullary nails. There were 23 cases of CS (10.6%). Multivariate predictors of CS included age 14 years and older (21/96 = 22%, p < 0.001) and motor vehicle accident (MVA) (12/57 = 21%, p = 0.002). Incidence of CS was 44% among patients 14 and older who sustained MVA (11 of 25). Gender, AO fracture type, time to surgery and surgical fixation were not predictive of CS. Conclusion. This is the first large study to report the incidence of CS from TSF in children. The incidence of 10.6% is higher than previously reported and much higher in patients 14 years of age and older and involved in an MVA. Surgeons should be especially aware and suspicious of CS in children with tibial shaft fractures who have these risk factors

Introduction. Computer hexapod assisted orthopaedic surgery (CHAOS) has previously been shown to provide a predictable and safe method for correcting multiplanar femoral deformity. We report the outcomes of tibial deformity correction using CHAOS, as well as a new cohort of femoral CHAOS procedures. Materials and Methods. Retrospective review of medical records and radiographs for patients who underwent CHAOS for lower limb deformity at our tertiary centre between 2012–2020. Results. There were 70 consecutive cases from 56 patients with no loss to follow-up. Mean age was 40 years (17 to 77); 59% male. There were 48 femoral and 22 tibial procedures. Method of fixation was intramedullary nailing in 47 cases and locking plates in 23. Multiplanar correction was required in 43 cases. The largest correction of rotation was 40 degrees, and angulation was 28 degrees. Mean mechanical axis deviation reduction per procedure was 17.2 mm, maximum 89 mm. Deformity correction was mechanically satisfactory in all patients bar one who was under-corrected, requiring revision. Complications from femoral surgery included one under-correction, two cases of non-union, and one pulmonary embolism. Complications from tibial surgery were one locking plate fatigue failure, one compartment syndrome, one pseudoaneurysm of the anterior tibial artery requiring stenting, and one transient neurapraxia of the common peroneal nerve. There were no deaths. Conclusions. CHAOS can be used for reliable correction of complex deformities of both the femur and tibia. The risk profile appears to differ between femoral and tibial surgeries

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

Recent literature has demonstrated that conventional arthroscopic techniques do not adequately visualise areas of predilection of pathology of the long head of biceps (LHB) tendon and are associated with a 30–50% rate of missed diagnoses. The aim of this study was to evaluate the safety, effectiveness and ease of performing biceps tenoscopy as a novel strategy for reducing the rate of missed diagnoses. Five forequarter amputation cadaver specimens were studied. The pressure in the anterior compartment was measured before and after surgical evaluation. Diagnostic glenohumeral arthroscopy was performed and the biceps tendon was tagged to mark the maximum length visualised by pulling the tendon into the joint. Biceps tenoscopy was performed using 3 different techniques (1. Flexible video-endoscopy, 2. Standard arthroscopy via Neviaser portal. 3. Standard arthroscope via antero-superior portal with retrograde instrumentation). Each was assessed for safety, ease of the procedure and whether the full length of the extra-articular part of the LHB tendon could be visualised. The t-test was used to compare the length of the LHB tendon visualised at standard glenohumeral arthroscopy vs that visualised at biceps tenoscopy. An open dissection was performed after the arthroscopic procedures to evaluate for an iatrogenic injury to local structures. Biceps tenoscopy allowed visualisation to the musculotendinous junction in all cases. The mean length of the tendon visualised was therefore significantly greater at biceps tenoscopy (104 mm) than at standard glenohumeral arthroscopy (33 mm) (mean difference 71 mm, p<0.0001). Biceps tenoscopy was safe with regards to compartment syndrome and there was no difference between pre- and post-operative pressure measurements (mean difference 0 mmHg, p=1). No iatrogenic injuries were identified at open dissection. Biceps tenoscopy allows excellent visualisation of the entire length of the LHB tendon and therefore has the potential to reduce the rate of missed diagnoses. This study did not demonstrate any risk of iatrogenic injury to important local structures or any risk of compartment syndrome. Clinical evaluation is required to further validate this technique

Introduction. Open fractures are fortunately rare but pose an even greater challenge due to poor soft tissues, in addition to poor bone quality. Co-morbidities and pre-existing medical conditions, in particular, peripheral vascular diseases make them often unsuitable for free flaps. We present our experience in treating severe open fractures of tibia with Acute Intentional Deformation (AID) to close the soft tissues followed by gradual correction of deformity to achieve anatomical alignment of the tibia and fracture healing with Taylor Spatial Frame. Materials and Methods. We treated 4 geriatric (3 female and 1 male) patients with Gustillo-Anderson III B fractures of the tibia between 2017–18. All were unfit to undergo orthoplastic procedures (free flap or local flaps). The age range is 69 yrs to 92 years. Co-morbidities included severe rheumatoid arthritis, multiple sclerosis and heart failure. The procedure involved wound debridement, application of two ring Taylor Spatial Frame, acute deformation of the limb on the table to achieve soft-tissue closure/approximation. Regular neurovascular assessments were performed in the immediate post-operative period to monitor for compartment syndrome and nerve compression symptoms. After 7–10 days of latent period, the frame was gradually manipulated, according to a method we had previously published, to achieve anatomical alignment. The frame was removed in clinic after fracture healing. Results. Time in frame ranged from 1.5 months to 7 months. In one patient (92 yr old with an open fracture of the ankle) hindfoot nail was inserted after soft-tissue closure was achieved at 1.5 months, and frame removed. We achieved complete healing of soft tissue wounds without any input from plastic surgeons in all patients. All fractures healed in anatomical alignment. 3 patients had one episode of superficial pin infection each requiring 5 days of oral antibiotics. None of the patients developed a deep infection. Conclusions. Acute intentional deformation (AID) with Taylor Spatial Frame achieves good closure of soft tissues in physiologically compromised geriatric patients who were deemed unfit for plastic surgery. We also achieved fracture healing in all four cases without any major complications

Aims. Computer hexapod assisted orthopaedic surgery (CHAOS), is a method to achieve the intra-operative correction of long bone deformities using a hexapod external fixator before definitive internal fixation with minimally invasive stabilisation techniques. The aims of this study were to determine the reliability of this method in a consecutive case series of patients undergoing femoral deformity correction, with a minimum six-month follow-up, to assess the complications and to define the ideal group of patients for whom this treatment is appropriate. Patients and Methods. The medical records and radiographs of all patients who underwent CHAOS for femoral deformity at our institution between 2005 and 2011 were retrospectively reviewed. Records were available for all 55 consecutive procedures undertaken in 49 patients with a mean age of 35.6 years (10.9 to 75.3) at the time of surgery. Results. Patients were assessed at a mean interval of 44 months (6 to 90) following surgery. The indications were broad; the most common were vitamin D resistant rickets (n = 10), growth plate arrest (n = 6) and post-traumatic deformity (n = 20). Multi-planar correction was required in 33 cases. A single level osteotomy was performed in 43 cases. Locking plates were used to stabilise the osteotomy in 33 cases and intramedullary nails in the remainder. Complications included two nonunions, one death, one below-knee deep vein thrombosis, one deep infection and one revision procedure due to initial under-correction. There were no neurovascular injuries or incidence of compartment syndrome. Conclusion. This is the largest reported series of femoral deformity corrections using the CHAOS technique. This series demonstrates that precise intra-operative realignment is possible with a hexapod external fixator prior to definitive stabilisation with contemporary internal fixation. This combination allows reproducible correction of complex femoral deformity from a wide variety of diagnoses and age range with a low complication rate.

We report the results of using a combination of fixator-assisted nailing with lengthening over an intramedullary nail in patients with tibial deformity and shortening. Between 1997 and 2007, 13 tibiae in nine patients with a mean age of 25.4 years (17 to 34) were treated with a unilateral external fixator for acute correction of deformity, followed by lengthening over an intramedullary nail with a circular external fixator applied at the same operating session. At the end of the distraction period locking screws were inserted through the intramedullary nail and the external fixator was removed. The mean amount of lengthening was 5.9 cm (2 to 8). The mean time of external fixation was 90 days (38 to 265). The mean external fixation index was 15.8 days/cm (8.9 to 33.1) and the mean bone healing index was 38 days/cm (30 to 60). One patient developed an equinus deformity which responded to stretching and bracing. Another developed a drop foot due to a compartment syndrome, which was treated by fasciotomy. It recovered in three months. Two patients required bone grafting for poor callus formation. We conclude that the combination of fixator-assisted nailing with lengthening over an intramedullary nail can reduce the overall external fixation time and prevent fractures and deformity of the regenerated bone

Introduction. We retrospectively evaluated our five years' experience in using Expandable Fixion nail system in tibial diaphyseal fractures. Materials/Methods. Eighteen cases with closed tibial diaphyseal fracture were identified between January 2006 and January 2011, all treated successfully with Fixion intramedullary nail as a primary osteosynthesis device. Results. All patients were followed-up in our department until clinical and radiological fusion was achieved with a mean follow-up of 13 months (range 6–20 months). There was one asymptomatic delayed union at 13 months, treated with regular observation until fusion was achieved. There was no incidence of infection, compartment syndrome or non-union in this group. Conclusion. We conclude from our experience that Expandable Fixion Nail is as effective as traditional locking intramedullary nail system in treating closed tibial shaft fracture with the advantages of shorter theatre time and less radiation exposure

Limited literature exists providing comprehensive assessment of complications following opening wedge high tibial osteotomy (OWHTO). We performed a retrospective study of local patients who underwent OWHTO for isolated medial compartment knee osteoarthritis from 1997–2013. One hundred and fifteen patients met inclusion criteria. Mean follow-up = 8.4years. Mean age = 47 (range 32–62). Mean BMI = 29.1 (range 20.3–40.2). Implants used included Tomofix (72%), Puddu plate (21%) and Orthofix (7%) (no significant differences in age/ sex/ BMI). Wedge defects were filled with autologous graft (30%), Chronos (35%) or left empty (35%). Five year survival rate (conversion to arthroplasty) = 80%. Overall complication rate = 31%. 25% of patients suffered 36 complications including minor wound infections (9.6%), major wound infections (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%). No thromboembolic complications were observed. A higher BMI (mean 34.2) was apparent in those patients suffering complications than those not (mean 26.9). No significant differences existed in complication rates relative to implant type, type of bone graft used or patient age at surgery. Complications following OWHTO appear higher than previously reported in the literature; serious complications appear rare

Purpose of Study:. To review the outcome of paediatric patients with radius and ulna fractures treated with titanium elastic nails. Description of methods:. Paediatric patients with radius and ulna fractures who fulfilled the criteria for TENS nailing were used. The criteria included failed closed reduction, instability (>15°angulation, >5°rotation) and open fractures. The patients were treated with retrograde TENS nailing of the radius and ulna. The patients were followed up at a paediatric orthopaedic outpatient clinic at 1, 3, 6 and 12 weeks with a final visit at 6 months. Data was collected at every visit looking at range of motion (pronation and supination), clinical and radiological signs of union and complications. Summary of results:. Over a 16 month period, 214 paediatric patients with radius and ulna fractures were seen and managed. Eleven of these patients were treated with TENS nails. The average age of the patient was 8.3 years. The average time to union was 8.5 weeks. The average range of motion at 6 months was pronation of 80°and supination of 73°. Two patients developed a compartment syndrome in the immediate post-operative period and were treated with a fasciotomy and skin grafting. No other complications were noted. Conclusion:. TENS nailing of paediatric radius and ulna fractures in unstable, irreducible and open fractures is a good treatment modality with good, early union of fractures and acceptable range of motion. It provides an excellent alternative to plating these fractures

Purpose of the study. To assess use of Taylor Spatial Frame to correct posttraumatic equinus contracture of ankle by soft tissue distraction. Description of a successful technique. Methods and end results. We have treated five cases of severe and resistant equinus contracture (20–30 degrees) between 2005 and 2010. All cases resulted from severe soft tissue injury and compartment syndrome of affected limb. They had undergone prolonged treatment for open fracture of tibia prior to referral to our institute and failed to respond to at least six months of aggressive physiotherapy. In all cases fractures did not involve ankle articular surface and all tibial fractures had united. Three out five cases also had associated peroneal nerve palsy. Our procedure included Tendo Achilles Lengthening, ankle and subtalar capsulotomy and application of two-ring Taylor Spatial Frame. We used long bone module to correct the deformity gradually. All deformities were over corrected by 5–10% to prevent recurrence. We successfully corrected equinus deformity in all cases. Follow up ranged from three months to five years and we found no recurrence. Patients with peroneal palsy were provided with Ankle Foot Orthosis (AFO). Conclusion. Taylor Spatial Frame treatment provides a safe, finely controllable, accurate and reproducible method of correcting soft tissue equinus deformity

Claims for clinical negligence are increasing annually. Limb reconstructive surgery recognises ‘problems, obstacles, and complications’ as part of the treatment process, but this does not prevent a claim for an alleged poor result or a complication. We analysed claims for clinical negligence in the National Health Service in England and Wales for issues following limb reconstructive surgery. A database of all 10,456 claims related to Trauma and Orthopaedic Surgery from 1995–2010 was obtained from the NHS Litigation Authority. A Search Function for keywords “Ilizarov, limb reconstruction, external fixation, and pin-site” was used for subset analysis. Data was analysed for type of complaint, whether defended or not, and for costs. 52 claims fitted our filters - 48 were closed, and 4 ongoing. The claims included damage to local structures (n=3), missed compartment syndrome (n=2), premature frame removal (n=5), infection (n=13), wrong-site-surgery (n=1), poor outcome (n=16) and technical error (n=10). Seven patients underwent amputation. The total cost of litigation was £4,444,344, with a mean of £90,700 per settled claim. 40% were successfully defended, with defence cost of £15,322. The mean pay-out for confirmed negligence/liability was £90,056 (£1,500-£419,999, median £45,000) per case. We believe this is the first study looking at complications following limb reconstruction from this perspective. Analysis reveals a spectrum of claims for negligence. Perceived technical errors and poor outcome predominate. Whilst the limitations of the database preclude against identification of whether the procedures were carried out in specialist units, claims for technical errors are a cause for concern. These will be discussed in detail. Outcomes following limb reconstruction are difficult to quantify, and the settling of claims for a perceived poor outcome makes the case for pre-operative counselling and the need for robust outcome measures in our specialty

Vascularised soft tissue transfer may be helpful in the salvage of severe sepsis involving avascular tissues hosting joint replacements or other metal work. Transferred tissue covers the exposed implants and delivers intravenous antibiotics. Twenty-one cases for the knee, elbow and shoulder are presented. Gastrocnemius flaps were used for seven knee replacements and 10 knee fractures. Antegrade radial artery flaps were used for two elbow replacements. Pectoralis major or minor flaps were used for two shoulder replacements. All procedures were performed by an orthopaedic surgeon with supplementary plastics training. Synchronous bony surgery included revision arthroplasty in seven cases, conversion to fusion in one case and preservation of existing hardware in the remainder. Sepsis was eliminated in the longterm in 9 of 10 knee fracture fixation cases, 5 out of 7 knee replacements and both elbow replacements. Both shoulder replacements remained septic despite multiple repeat procedures. Complications included necrosis of two gastrocnemius flaps, one from pre-existing partial compartment syndrome and one when combined with fusion of the knee. One other knee replacement developed further sepsis three years post procedure. No limb required amputation. These procedures are well within the remit of orthopaedic surgeons, the non reliance on plastics surgeons allowed prompt treatment combined with bony procedures. Results were good for the knee and elbow but disappointing for the shoulder—this, probably related to the natural mobility of the joint

The outcome of 77 high energy tibial plateau fractures treated by locking or conventional plating was reviewed. The aim of the study was to determine if there was any advantage of locking plates in reducing the complication rates associated with fixation of these injuries. All patients had a high energy injury pattern (medial or bicondylar plateau fractures). There were 32 locked plates and 45 non-locking plates used. Compartment syndrome complicated 5 patients (16%) in the locked plate group and 3 (7%) in the non-locked group (p = 0.198). Superficial infection occurred in 4 (13%) patients with locked plates and 7 (16%) patients with non-locked plates. Thromboembolic complications occurred in 3 (7%) patients treated with non-locked plates. There were no thrombembolic complications in the locked plate group (p = 0.135). Overall, malunion of the plateau occurred in 10 (22%) patients treated with non-locked plates compared to 7 (22%) patients who received locked plates. This was due to residual malreduction in 4 (13%) patients in the locked plate group and 6 (13%) patients in the non-locked plate group at the time of surgery. In the remaining cases loss of reduction after fixation occurred in 4 (9%) patients who received non-locked plates and in 3 (9%) patients who were treated with locked plates. No statistically significant difference was noted in the treatment outcomes of patients managed with locked plates or non-locked plates, regardless of fracture severity. We concluded that there is no definite advantage associated with the use of locked plating for high energy tibial plateau fractures
