Methods:. Total radiation exposure accumulated during circular frame treatment of distal tibial fractures was quantified in 47 patients treated by a single surgeon from March 2011 until Nov 2014. The radiation exposures for all relevant radiology procedures for the distal tibial injury were included to estimate the radiation risk to the patient. Results:. The median time of treatment in the frame was 169 days (range 105 – 368 days). Patients underwent a median of 13 sets of plain radiographs; at least one intra operative exposure and 16 patients underwent CT scanning. The median total effective dose per patient from time of injury to discharge was 0.025 mSv (interquartile range 0.013 – 0.162 and minimum to maximum 0.01–0.53). CT scanning is the only variable shown to be an independent predictor of cumulative radiation dose on multivariate analysis, with a 13 fold increase in overall exposure. Conclusion:. Radiation exposure during treatment of distal tibial fractures with a circular frame in this group was well within reasonably safe limits. CT was the only significant predictor of overall exposure serves as a reminder to individually assess the risk and utility of radiological investigations on an individual basis. This is consistent with the UK legal requirements (Ionising Radiation (Medical Exposure) Regulations 2000. 1. )

Radiation exposure is a hazard to orthopaedic surgeons, theatre staff and patients intra-operatively. Obesity is becoming a more prevalent problem worldwide and there is little evidence how a patient's body habitus correlates with the radiation doses required to penetrate the soft tissues for adequate imaging. We aimed to identify if there was a correlation between Body Mass Index (BMI) and radiation exposure intra-operatively. We performed a retrospective review of 75 patients who underwent sliding hip screw fixation for femoral neck fractures in one year. We recorded Body Mass Index (BMI), screening time, dose area product (DAP), American Society of Anesthesiologists (ASA) grade, seniority of surgeon and complexity of the fracture configuration. We analysed the data using statistical tests. We found that there was a statistically significant correlation between dose area product and patient's BMI. There was no statistically significant relationship between screening time and BMI. There was no statistical difference between ASA grade, seniority of surgeon, or complexity of fracture configuration and dose area product. Obese patients are exposed to increased doses of radiation regardless of length of screening time. Surgeons and theatre staff should be aware of the increased radiation exposure during fixation of fractures in obese patients and, along with radiographers, ensure steps are taken to minimise these risks

We measured the scattered radiation received by theatre staff, using high-sensitivity electronic personal dosimeters, during fixation of extracapsular fractures of the neck of the femur by dynamic hip screw. The dose received was correlated with that received by the patient, and the distance from the source of radiation. A scintillation detector and a water-filled model were used to define a map of the dose rate of scattered radiation in a standard operating theatre during surgery. Beyond two metres from the source of radiation, the scattered dose received was consistently low, while within the operating distance that received by staff was significant for both lateral and posteroanterior (PA) projections. The routine use of lead aprons outside the 2 m zone may be unnecessary. Within that zone it is recommended that lead aprons be worn and that thyroid shields are available for the surgeon and nursing assistants

Introduction. Radiation exposure to the eye causes cataracts. Few orthopaedists wear leaded glasses when using fluoroscopy despite regulatory limits for maximum annual eye exposure. Methods. Using anthropomorphic patient and surgeon phantoms, radiation dose at the surgeon phantom's lens was measured with and without leaded glasses during fluroscopic acquisition of 16 common pelvic and hip views. The magnitude of lens dose reduction was calculated by dividing the unprotected dose by the dose measured behind leaded glasses. Results. The unprotected lens dose varied considerably among the different views, ranging from 0 μRem for a single obturator oblique pelvic view, to 257 μRem for a single lateral sacral view with the image intensifier opposite the surgeon. On average, use of leaded glassess reduced radiation to the surgeon phantom's eye by 90%. The greatest reduction was seen with a crosstable lateral radiograph of the hip (22 μRem unprotected lens dose vs. 1 μRem with leaded glasses). Conclusions. The use of leaded glasses could permit an orthopaedist to perform up to 10 times more cases before reaching the annual limit of 20 mSv (20 mSv = 2×10. 6. mRem). A large number of images are often required during a single operative procedure and varies greatly between cases. The number of cases which a surgeon can safely perform without leaded glasses is dependent on the number and type of images, and location of the surgeon with respect to the image intensifier

Aims. Ankle fracture fixation is commonly performed by junior trainees. Simulation training using cadavers may shorten the learning curve and result in a technically superior surgical performance. Methods. We undertook a preliminary, pragmatic, single-blinded, multicentre, randomized controlled trial of cadaveric simulation versus standard training. Primary outcome was fracture reduction on postoperative radiographs. Results. Overall, 139 ankle fractures were fixed by 28 postgraduate year three to five trainee surgeons (mean age 29.4 years; 71% males) during ten months' follow-up. Under the intention-to-treat principle, a technically superior fixation was performed by the cadaveric-trained group compared to the standard-trained group, as measured on the first postoperative radiograph against predefined acceptability thresholds. The cadaveric-trained group used a lower intraoperative dose of radiation than the standard-trained group (mean difference 0.011 Gym. 2. , 95% confidence interval 0.003 to 0.019; p = 0.009). There was no difference in procedure time. Conclusion. Trainees randomized to cadaveric training performed better ankle fracture fixations and irradiated patients less during surgery compared to standard-trained trainees. This effect, which was previously unknown, is likely to be a consequence of the intervention. Further study is required. Cite this article: Bone Jt Open 2023;4(8):594–601

Aims. To evaluate if, for orthopaedic trainees, additional cadaveric simulation training or standard training alone yields superior radiological and clinical outcomes in patients undergoing dynamic hip screw (DHS) fixation or hemiarthroplasty for hip fracture. Methods. This was a preliminary, pragmatic, multicentre, parallel group randomized controlled trial in nine secondary and tertiary NHS hospitals in England. Researchers were blinded to group allocation. Overall, 40 trainees in the West Midlands were eligible: 33 agreed to take part and were randomized, five withdrew after randomization, 13 were allocated cadaveric training, and 15 were allocated standard training. The intervention was an additional two-day cadaveric simulation course. The control group received standard on-the-job training. Primary outcome was implant position on the postoperative radiograph: tip-apex distance (mm) (DHS) and leg length discrepancy (mm) (hemiarthroplasty). Secondary clinical outcomes were procedure time, length of hospital stay, acute postoperative complication rate, and 12-month mortality. Procedure-specific secondary outcomes were intraoperative radiation dose (for DHS) and postoperative blood transfusion requirement (hemiarthroplasty). Results. Eight female (29%) and 20 male trainees (71%), mean age 29.4 years, performed 317 DHS operations and 243 hemiarthroplasties during ten months of follow-up. Primary analysis was a random effect model with surgeon-level fixed effects of patient condition, patient age, and surgeon experience, with a random intercept for surgeon. Under the intention-to-treat principle, for hemiarthroplasty there was better implant position in favour of cadaveric training, measured by leg length discrepancy ≤ 10 mm (odds ratio (OR) 4.08 (95% confidence interval (CI) 1.17 to 14.22); p = 0.027). There were significantly fewer postoperative blood transfusions required in patients undergoing hemiarthroplasty by cadaveric-trained compared to standard-trained surgeons (OR 6.00 (95% CI 1.83 to 19.69); p = 0.003). For DHS, there was no significant between-group difference in implant position as measured by tip-apex distance ≤ 25 mm (OR 6.47 (95% CI 0.97 to 43.05); p = 0.053). No between-group differences were observed for any secondary clinical outcomes. Conclusion. Trainees randomized to additional cadaveric training performed hip fracture fixation with better implant positioning and fewer postoperative blood transfusions in hemiarthroplasty. This effect, which was previously unknown, may be a consequence of the intervention. Further study is required. Cite this article: Bone Jt Open 2023;4(8):602–611

Aims. Occult (clinical) injuries represent 15% of all scaphoid fractures, posing significant challenges to the clinician. MRI has been suggested as the gold standard for diagnosis, but remains expensive, time-consuming, and is in high demand. Conventional management with immobilization and serial radiography typically results in multiple follow-up attendances to clinic, radiation exposure, and delays return to work. Suboptimal management can result in significant disability and, frequently, litigation. Methods. We present a service evaluation report following the introduction of a quality-improvement themed, streamlined, clinical scaphoid pathway. Patients are offered a removable wrist splint with verbal and written instructions to remove it two weeks following injury, for self-assessment. The persistence of pain is the patient’s guide to ‘opt-in’ and to self-refer for a follow-up appointment with a senior emergency physician. On confirmation of ongoing signs of clinical scaphoid injury, an urgent outpatient ‘fast’-wrist protocol MRI scan is ordered, with instructions to maintain wrist immobilization. Patients with positive scan results are referred for specialist orthopaedic assessment via a virtual fracture clinic. Results. From February 2018 to January 2019, there were 442 patients diagnosed as clinical scaphoid fractures. 122 patients (28%) self-referred back to the emergency department at two weeks. Following clinical review, 53 patients were discharged; MRI was booked for 69 patients (16%). Overall, six patients (< 2% of total; 10% of those scanned) had positive scans for a scaphoid fracture. There were no known missed fractures, long-term non-unions or malunions resulting from this pathway. Costs were saved by avoiding face-to-face clinical review and MRI scanning. Conclusion. A patient-focused opt-in approach is safe and effective to managing the suspected occult (clinical) scaphoid fracture. Cite this article: Bone Jt Open 2024;5(2):117–122

Aims. We compared the accuracy, operating time and radiation exposure of the introduction of iliosacral screws using O-arm/Stealth Navigation and standard fluoroscopy. Materials and Methods. Iliosacral screws were introduced percutaneously into the first sacral body (S1) of ten human cadavers, four men and six women. The mean age was 77 years (58 to 85). Screws were introduced using a standard technique into the left side of S1 using C-Arm fluoroscopy and then into the right side using O-Arm/Stealth Navigation. The radiation was measured on the surgeon by dosimeters placed under a lead thyroid shield and apron, on a finger, a hat and on the cadavers. Results. There were no neuroforaminal breaches in either group. The set-up time for the O-Arm was significantly longer than for the C-Arm, while total time for placement of the screws was significantly shorter for the O-Arm than for the C-Arm (p = 0.001). The mean absorbed radiation dose during fluoroscopy was 1063 mRad (432.5 mRad to 4150 mRad). No radiation was detected on the surgeon during fluoroscopy, or when he left the room during the use of the O-Arm. The mean radiation detected on the cadavers was significantly higher in the O-Arm group (2710 mRem standard deviation (. sd. ) 1922) than during fluoroscopy (11.9 mRem . sd 14.8). (p < 0.01). Conclusion. O-Arm/Stealth Navigation allows for faster percutaneous placement of iliosacral screws in a radiation-free environment for surgeons, albeit with the same accuracy and significantly more radiation exposure to cadavers, when compared with standard fluoroscopy. Take home message: Placement of iliosacral screws with O-Arm/Stealth Navigation can be performed safely and effectively. Cite this article: Bone Joint J 2016;98-B:696–702

Aims. To evaluate whether an ultra-low-dose CT protocol can diagnose selected limb fractures as well as conventional CT (C-CT). Patients and Methods. We prospectively studied 40 consecutive patients with a limb fracture in whom a CT scan was indicated. These were scanned using an ultra-low-dose CT Reduced Effective Dose Using Computed Tomography In Orthopaedic Injury (REDUCTION) protocol. Studies from 16 selected cases were compared with 16 C-CT scans matched for age, gender and type of fracture. Studies were assessed for diagnosis and image quality. Descriptive and reliability statistics were calculated. The total effective radiation dose for each scanned site was compared. Results. The mean estimated effective dose (ED) for the REDUCTION protocol was 0.03 milliSieverts (mSv) and 0.43 mSv (p < 0.005) for C-CT. The sensitivity (Sn), specificity (Sp), positive predictive value (PPV) and negative predictive value (NPV) of the REDUCTION protocol to detect fractures were 0.98, 0.89, 0.98 and 0.89 respectively when two occult fractures were excluded. Inter- and intra-observer reliability for diagnosis using the REDUCTION protocol (κ = 0.75, κ = 0.71) were similar to those of C-CT (κ = 0.85, κ = 0.82). Using the REDUCTION protocol, 3D CT reconstructions were equivalent in quality and diagnostic information to those generated by C-CT (κ = 0.87, κ = 0.94). Conclusion. With a near 14-fold reduction in estimated ED compared with C-CT, the REDUCTION protocol reduces the amount of CT radiation substantially without significant diagnostic decay. It produces images that appear to be comparable with those of C-CT for evaluating fractures of the limbs. Cite this article: Bone Joint J 2016;98-B:1668-73

We compared the outcome of closed intramedullary nailing with minimally invasive plate osteosynthesis using a percutaneous locked compression plate in patients with a distal metaphyseal fracture in a prospective study. A total of 85 patients were randomised to operative stabilisation either by a closed intramedullary nail (44) or by minimally invasive osteosynthesis with a compression plate (41). Pre-operative variables included the patients’ age and the side and pattern of the fracture. Peri-operative variables were the operating time and the radiation time. Postoperative variables were wound problems, the time to union of the fracture, the functional American Orthopaedic Foot and Ankle surgery score and removal of hardware. We found no significant difference in the pre-operative variables or in the time to union in the two groups. However, the mean radiation time and operating time were significantly longer in the locked compression plate group (3.0 vs 2.12 minutes, p < 0.001, and 97.9 vs 81.2 minutes, p < 0.001, respectively). After one year, all the fractures had united. Patients who had intramedullary nailing had a higher mean pain score, but better function, alignment and total American Orthopaedic Foot and Ankle surgery scores, although the differences were not statistically significant (p = 0.234, p = 0.157, p = 0.897, p = 0.177 respectively). Three (6.8%) patients in the intramedullary nailing group and six (14.6%) in the locked compression plate group showed delayed wound healing, and 37 (84.1%) in the former group and 38 (92.7%) in the latter group expressed a wish to have the implant removed. We conclude that both closed intramedullary nailing and a percutaneous locked compression plate can be used safely to treat Orthopaedic Trauma Association type-43A distal metaphyseal fractures of the tibia. However, closed intramedullary nailing has the advantage of a shorter operating and radiation time and easier removal of the implant. We therefore prefer closed intramedullary nailing for patients with these fractures

We compared the outcome of patients treated for an intertrochanteric fracture of the femoral neck with a locked, long intramedullary nail with those treated with a dynamic hip screw (DHS) in a prospective randomised study. Each patient who presented with an extra-capsular hip fracture was randomised to operative stabilisation with either a long intramedullary Holland nail or a DHS. We treated 92 patients with a Holland nail and 98 with a DHS. Pre-operative variables included the Mini Mental test score, patient mobility, fracture pattern and American Society of Anesthesiologists grading. Peri-operative variables were anaesthetic time, operating time, radiation time and blood loss. Post-operative variables were time to mobilising with a frame, wound infection, time to discharge, time to fracture union, and mortality. We found no significant difference in the pre-operative variables. The mean anaesthetic and operation times were shorter in the DHS group than in the Holland nail group (29.7 vs 40.4 minutes, p < 0.001; and 40.3 vs 54 minutes, p < 0.001, respectively). There was an increased mean blood loss within the DHS group versus the Holland nail group (160 ml vs 78 ml, respectively, p < 0.001). The mean time to mobilisation with a frame was shorter in the Holland nail group (DHS 4.3 days, Holland nail 3.6 days, p = 0.012). More patients needed a post-operative blood transfusion in the DHS group (23 vs seven, p = 0.003) and the mean radiation time was shorter in this group (DHS 0.9 minutes vs Holland nail 1.56 minutes, p < 0.001). The screw of the DHS cut out in two patients, one of whom underwent revision to a Holland nail. There were no revisions in the Holland nail group. All fractures in both groups were united when followed up after one year. We conclude that the DHS can be implanted more quickly and with less exposure to radiation than the Holland nail. However, the resultant blood loss and need for transfusion is greater. The Holland nail allows patients to mobilise faster and to a greater extent. We have therefore adopted the Holland nail as our preferred method of treating intertrochanteric fractures of the hip

Introduction. The assessment of the accuracy of reduction of the ankle syndesmosis has traditionally been made using plain radiographic measurements. Recent studies have shown that computerized tomography (CT) scan is more sensitive than radiographs in detecting diastasis. The ethos has now therefore shifted towards CT scan assessment of the syndesmosis. There is however no validated method to scan the syndesmosis and measure it on the CT scans. This exposes the patient to significant radiation risk and also to anxiety from inappropriate interpretation from these scans. The objectives of this research project are to investigate the current practice of CT scanning the syndesmosis at a University Hospital and to devise a new CT protocol to reduce radiation exposure to patients and to assist surgeons in interpreting the observations. Methods. Research Ethics Committee approval was obtained. Current practice was evaluated. A new 5 cut CT protocol was devised. Starting at the level of the distal tibial plafond, 5 cuts were made proximally 0.5 cm apart. Accuracy of the syndesmosis reduction was assessed just above the distal tibial plafond. Both the injured and the normal sides were scanned 12 weeks post surgery. The normal side served as a control. Results. Current practice revealed that patients had on an average 620 cuts CT scan with radiation exposure of 0.2 mSv. 25 patients were prospectively recruited for the new 5 cut CT protocol. The radiation exposure with the new protocol was only 0.002 mSv. Comparison with the normal side revealed that 5 (20%) of syndesmosis had residual diastasis. The only difficulty with the new protocol was getting both the ankle joint lines at the same level for the first CT cut. Discussion and Conclusion. Our CT scan protocol has insignificant radiation risk, even lower than a single chest radiograph. Comparing the measurements between the fractured and the normal sides provides an accurate assessment of the reduction of the syndesmosis. Significance of the measurements on the CT scan will be correlated with functional scores

Introduction. Locking nail have considerably improved the treatment of long weight bearing bones. However, distal locking needs experience and may expose to radiations. Many methods have been proposed to facilitate distal locking and improve safety. Recently, an external distal targeting device adapted to the ancillary of the Long Gamma Nail has been proposed. We report our experience with this device through a comparative series of distal lockings. Aim of this work was to assess feasibility and advantages brought about with this targeting device when considering time or dose of irradiation. Material and methods. Two prospective series of 50 distal locking performed by an experienced surgeon have been compared. Two methods were compared: the classical freehand technique using a Steinmann rod with the image of rounded holes, and the external distal targeting device. The following datas were collected: technical difficulties with either technique, locking mistakes and duration of exposure to radiations. Results. Two locking errors were observed using the targeting device, in pathological fractures with the use of a titanium nail. These cases belonged to the five earliest cases. External targeting device requires a learning curve that is reasonnably short with little difficulties encountered. Ther is a fundamental difference between the two series concerning exposure to radiations. In the freehand technique mean exposure was 25,8s (6–38) and it was 8,6s (6–18) with the dital targeting device. Discussion. A short learning curve confirms the ease of use of the distal targerting device. Diminution of exposure to radiation is effectively obtained. Some factors may increase the risk of error: the use of very long nails and the use of titanium nails as this may increase motion at distal end. Conclusion. The external visor is an efficient device as it facilitates distal locking and alllows for a diminution of irradiation time

Aims

Posterior column plating through the single anterior approach reduces the morbidity in acetabular fractures that require stabilization of both the columns. The aim of this study is to assess the effectiveness of posterior column plating through the anterior intrapelvic approach (AIP) in the management of acetabular fractures.

Introduction. Vitamin E stabilization of radiation crosslinked UHMWPE is done by (1) blending into the resin powder, consolidating and irradiating or (2) diffusing into already consolidated and irradiated UHMWPE and terminally gamma sterilizing. With blending, a higher radiation dose is required for crosslinking to the same level as virgin UHMWPE. With diffusion, the vitamin E amount used is not limited by the crosslink density, but, vitamin E is exposed to terminal sterilization dose of 25–40 kGy, less than the 100–150 kGy used with blending, which may decrease the grafting of the antioxidant onto the polymer. We investigated the efficiency of grafted vitamin E against squlene-initiated accelerated aging. Methods. Medical grade GUR1050 UHMWPE with vitamin E (0.1 wt%) was irradiated to 150 kGy. Tibial knee insert preforms were irradiated to 100 kGy, diffused with vitamin E using a doping and homogenization procedure. This UHMWPE was used either before or after gamma sterilization. One set of machined blocks (10 × 10 × 6 mm; n = 6) were extracted in boiling hexane for 4 days, then dried. The extracted blocks were doped with squalene at 120°C for 2 hours. One block each was analyzed after doping. The rest were accelerated aged at 70°C and 5 atm. of oxygen for 6 (n = 2) and 14 days (n = 3). Thin sections (150 micron thick) were microtomed and analyzed by Fourier Transform Infrared Spectroscopy to determine a vitamin E index (1245–1275 cm. −1. normalized to 1850–1985 cm. −1. ) and an oxidation index (1700 cm. −1. normalized to 1370 cm. −1. ) after extraction with boiling hexane for 16 hours and drying. Results. After extraction, 92% of the original vitamin E was removed from diffused and sterilized UHMWPE and 99% of the vitamin E was removed from the diffused and unsterilized UHMWPE. Vitamin E content of the blended, irradiated UHMWPEs could not be detected. As a result of accelerated aging in the presence of squalene, all extracted vitamin E-stabilized UHMWPEs showed increased oxidation except diffused, sterilized UHMWPE. The small amount grafted vitamin E in these samples (8%, ∼0.02 wt%) protected irradiated UHMWPE under these conditions. All vitamin E-stabilized, extracted UHMWPEs showed higher oxidative stability than irradiated and melted virgin UHMWPE in the presence of squalene. In the blended, irradiated UHMWPE, there was less effective vitamin E compared to the diffused, sterilized UHMWPE due to the high dose irradiation. Conclusions. Radiation grafting of vitamin E onto UHMWPE was effective against squalene initiated oxidation in accelerated aging. Vitamin E-diffused, sterilized UHMWPE showed no oxidation and diffused, unsterilized UHMWPE and blended, irradiated UHMWPE showed higher oxidative resistance than irradiated/melted UHMWPE

Aims

To determine whether platelet-rich plasma (PRP) injection improves outcomes two years after acute Achilles tendon rupture.

We report a prospective, randomised, blinded clinical comparison of the use of indomethacin or radiation therapy for the prevention of heterotopic ossification (HO) in 75 adults who had open reduction and internal fixation of acetabular fractures through either a Kocher-Langenbeck, a combined ilioinguinal and Kocher-Langenbeck, or an extended iliofemoral approach. Indomethacin, 25 mg, was given three times daily for six weeks. Radiation with 800 cGy was delivered within three days of operation. Plain radiographs were reviewed and given Brooker classification scores by three independent observers who were unaware of the method of prophylaxis. One patient died from unrelated causes and two were lost to follow-up, leaving 72, 33 in the radiation group and 39 in the indomethacin group, available for evaluation at a mean of 12 months (6 to 48). There was no significant difference in the two groups in terms of age, gender, injury severity score, estimated blood loss, delay to surgery, head injury, presence of femoral head dislocation, or operating time, and no complications due to either method of treatment. The final extent of HO was already present by six weeks in all patients who were followed up. Three patients in the radiation group and five who received indomethacin developed HO of Brooker grade III. Two patients in the indomethacin group developed Brooker IV changes; both had failed to receive proper doses of the drug. Cochran-Armitage analysis showed no significant difference between the two treatment groups as regards the formation of HO. Indomethacin and single-dose radiation therapy are both safe and effective for the prevention of HO after operation for acetabular fractures. Radiation therapy is, however, approximately 200 times more expensive than indomethacin therapy at our institution and has other risks

Aims

We introduced a self-care pathway for minimally displaced distal radius fractures, which involved the patient being discharged from a Virtual Fracture Clinic (VFC) without a physical review and being provided with written instructions on how to remove their own cast or splint at home, plus advice on exercises and return to function.

Background. In a systematic review of 1125 distal tibia fractures treated with an intramedullary nail, the reported incidence of malalignment was 14%. The purpose of our study is to assess whether the addition of blocking screws during intramedullary nailing of a distal tibia fracture improved radiological outcomes. As a secondary outcome, the time to radiographic union was compared to see if a more rigid bone-implant construct had an effect on healing. Methods. We searched computerised records at a UK level 1 major trauma centre. The joint alignment was measured on the immediate post-operative radiograph and compared to the most recent radiograph. We used a difference of 2 degrees to indicate a progressive deformity and a RUST score greater or equal to 10, to indicate radiographic fracture union. Results. Twenty-seven patients were included. Nineteen patients had no blocking screw and 8 patients had a blocking screw. Five patients had a difference in their coronal plane alignment of 2 degrees or more (3/5 had no blocking screw). The results were analysed and found to be not statistically significant (p=0.88). The addition of a blocking screw has also been shown not to have an effect on the time to union. Conclusion. We have changed our surgical practice. We use a 2.5mm blocking wire to aid in fracture reduction prior to reaming / nail insertion and then remove the wire when the nail has been adequately locked. Implications. This could save surgical procedure time, radiation exposure for the patient, implant costs and potential complications

Introduction. The Patient Archiving and Communication System (PACS) has revolutionised the way that radiographs are stored and viewed in orthopaedic surgery. A recent advance has been the ability to upload images directly from the image intensifier to PACS. We postulated that this facility may reduce the need for post operative ‘check’ radiographs following many orthopaedic trauma procedures. Patients and Method. We performed an audit of post-operative radiographs requested in our University Hospital over three time periods: 31 days immediately before the direct upload facility was introduced, 31 days immediately after and a 31 day period two months later. Details from the operating lists were cross-referenced with image intensifier records to identify cases where it had been used. PACS records were then checked to determine if these images were available to view and if a formal ‘check’ radiograph was performed in the period prior to discharge. Results. A total of 624 orthopaedic trauma operations were reviewed. In the period before direct-upload of images began, 62% of all trauma procedures utilised the image intensifier and in 26% post-operative ‘check’ radiographs were taken. In the period immediately after uploading began, the image intensifier was used in 66% of cases with 84% of these images being uploaded. Fifteen percent of the patients had a check radiograph during this period. Two months later the image intensifier was used in 67% of cases. Although 96% of these images were uploaded, 14% still had a formal post-operative radiograph. Conclusion. The facility to upload images from the image intensifier in the operating theatre directly onto the PACS system has reduced the number of post-operative ‘check’ radiographs requested in our trauma department by 11%. This has reduced both the cost and radiation exposure involved in orthopaedic trauma surgery but has not eliminated the need for post-operative radiographs completely
