Introduction. Manipulation under anesthesia (MUA) remains the gold standard to address restricted range of motion (ROM) within 3–6 months after primary total knee arthroplasty (TKA). However, there is little data on the outcomes of MUA with different types of anesthesia. We sought to compare the outcomes of patients undergoing MUA with intravenous (IV) sedation and neuraxial anesthesia. Methods. We identified 548 MUAs after primary TKA (136 IV sedation, 413 neuraxial anesthesia) at a single institution from 2016–2019. Mean age was 62 years and 349 patients (64%) were female. Mean body mass index was 32 kg/m. 2. The mean time from primary TKA to MUA was 10 weeks. Mean pre-MUA ROM was similar between each group; mean pre-MUA extension was 4.2° (p=0.35) and mean pre-MUA flexion was 77° (p=0.56). Patient demographics were statistically similar between both groups. We compared immediate complications, including fracture, extensor mechanism disruptions, and wound complications, Visual analogue pain scores (VAS), length of stay (LOS), and immediate and 3 month follow-up ROM between these groups. Results. No patients in either group sustained an immediate post-MUA complication. Patients undergoing MUA with IV sedation had significantly higher day of MUA average VAS of 5.1 compared to 4.1 in the neuraxial group (p<0.001). The average LOS was shorter in patients that received IV sedation (9 hours) compared to neuraxial anesthesia (12 hours) (p=0.009). Immediate-post MUA ROM was 1° – 121° in the IV sedation group and 0.9° – 123° in the neuraxial anesthesia group (p=0.21). Three month follow-up ROM was 2° – 108° in the IV sedation group and 1.9° – 110° in the neuraxial anesthesia group. Conclusion. IV sedation and neuraxial anesthesia are both effective anesthetic methods for patients undergoing MUA after primary TKA with minimal perioperative differences. Surgeons and anesthesiologists should cater anesthetic technique to patient specific needs as the orthopedic outcomes are similar for both methods; however, IV sedation resulted in a shorter LOS

Background. Procedural sedation (PS) requires two suitably qualified clinicians and a dedicated monitored bed space. We present the results of intra-articular haematoma blocks (IAHB), using local anaesthetic, for the manipulation of closed ankle fracture dislocations and compared resource use with PS. Methods. Patients received intra-articular ankle haematoma blocks for displaced ankle fractures requiring manipulation between October 2020 to April 2021. The technique used 10ml of 1% lignocaine injected anteromedially into the tibiotalar joint. Pain scores (VAS), time from first x-ray to reduction, and acceptability of reduction were recorded. A comparison was made by retrospective analysis of patients who had undergone PS for manipulation of an ankle fracture over the six month period March – August 2020. Results. During the periods assessed, 25 patients received an IAHB and 28 received PS for ankle fractures requiring manipulation (mean age 57.8yr vs 55.1yr). Time from first x-ray to manipulation was 65.9 min (IAHB) vs 82.9 min (PS) (p = 0.087). In the IAHB group mean pain scores pre, during and post manipulation were 6.1, 4.7 and 2.0 respectively (‘pre’ to ‘during’ p < 0.05; ‘pre’ to ‘post’ p < 0.01). In the IAHB group, 23 (92%) had a satisfactory reduction without need of PS or general anaesthetic. In the PS group 23 (82%) had a satisfactory reduction. There was no significant difference in the number of unsatisfactory first attempt reductions between the groups. There were no cases of deep infection post operatively in either group. Conclusion. Intra-articular haematoma block of the ankle appears to be an efficacious, safe and inexpensive means of providing analgesia for manipulation of displaced ankle fractures. Advantages of this method include avoiding the risks of procedural sedation, removing the requirement of designated clinical space and need for qualified clinicians to give sedation, and the ability to re-manipulate under the same block

Neuromuscular scoliosis patients face rates of major complications of up to 49%. Along with pre-operative risk reduction strategies (including nutritional and bone health optimization), intra-operative strategies to decrease blood loss and decrease surgical time may help mitigate these risks. A major contributor to blood loss and surgical time is the insertion of instrumentation which is challenging in neuromuscular patient given their abnormal vertebral and pelvic anatomy. Standard pre-operative radiographs provide minimal information regarding pedicle diameter, length, blocks to pedicle entry (e.g. iliac crest overhang), or iliac crest orientation. To minimize blood loss and surgical time, we developed an “ultra-low dose” CT protocol without sedation for neuromuscular patients. Our prospective quality improvement study aimed to determine: if ultra-low dose CT without sedation was feasible given the movement disorders in this population; what the radiation exposure was compared to standard pre-operative imaging; whether the images allowed accurate assessment of the anatomy and intra-operative navigation given the ultra-low dose and potential movement during the scan. Fifteen non-ambulatory surgical patients with neuromuscular scoliosis received the standard spine XR and an ultra-low dose CT scan. Charts were reviewed for etiology of neuromuscular scoliosis and medical co-morbidities. The CT protocol was a high-speed, high-pitch, tube-current modulated acquisition at a fixed tube voltage. Adaptive statistical iterative reconstruction was applied to soft-tissue and bone kernels to mitigate noise. Radiation dose was quantified using reported dose indices (computed tomography dose index (CTDIvol) and dose-length product (DLP)) and effective dose (E), calculated through Monte-Carlo simulation. Statistical analysis was completed using a paired student's T-test (α = 0.05). CT image quality was assessed for its use in preoperative planning and intraoperative navigation using 7D Surgical System Spine Module (7D Surgical, Toronto, Canada). Eight males and seven females were included in the study. Their average age (14±2 years old), preoperative Cobb angle (95±21 degrees), and kyphosis (60±18 degrees) were recorded. One patient was unable to undergo the ultra-low dose CT protocol without sedation due to a co-diagnosis of severe autism. The average XR radiation dose was 0.5±0.3 mSv. Variability in radiographic dose was due to a wide range in patient size, positioning (supine, sitting), number of views, imaging technique and body habitus. Associated CT radiation metrics were CTDIvol = 0.46±0.14 mGy, DLP = 26.2±8.1 mGy.cm and E = 0.6±0.2 mSv. CT radiation variability was due to body habitus and arm orientation. The radiation dose differences between radiographic and CT imaging were not statistically significant. All CT scans had adequate quality for preoperative assessment of pedicle diameter and orientation, obstacles impeding pedicle entry, S2-Alar screw orientation, and intra-operative navigation. “Ultra-low dose” CT scans without sedation were feasible in paediatric patients with neuromuscular scoliosis. The effective dose was similar between the standard preoperative spinal XR and “ultra-low dose” CT scans. The “ultra-low dose” CT scan allowed accurate assessment of the anatomy, aided in pre-operative planning, and allowed intra-operative navigation despite the movement disorders in this patient population

Abstract. Objective. To investigate the safety and cost-effectiveness of interscalene brachial plexus block/regional anaesthesia (ISB-RA) in patients undergoing reverse total shoulder replacement. Methods. This retrospective study included 15 patients with symptomatic rotator cuff arthropathy who underwent reverse total shoulder arthroplasty (rTSA) under ISB-RA without general anaesthesia in the beach chair position from 2010 to 2018. The mean patient age was 77 years (range 59–82 years). Patients had associated medical comorbidities: American Society of Anesthesiologists (ASA) grade 2–4. Assessed parameters were: duration of anaesthesia, intra-operative systolic blood pressure variation, sedation and vasopressor use, duration of post-operative recovery, recovery scores, length of stay, and complications. A robust cost analysis was also performed. Results. The mean (range) duration of anaesthesia was 38.66 (20–60) min. Maximum and minimum intra-operative systolic blood pressure ranges were 130–210 and 75–145 mmHg, respectively (mean [range] drop, 74.13 [33–125] mmHg). Mean (range) propofol dose was 1.74 (1–3.0) mg/kg/h. The Median (interquartile range) post-operative recovery time was 30 (20–50) min. The mean (range) postoperative recovery score (local scale, range 5–28 where lower values are superior) was 5.2 (5–8). The mean (range) length of stay was 8 (1–20 days); the two included patients with ASA grade 2 were both discharged within 24 hours. One patient with predisposing history developed pneumonia; however, there were no complications related to ISB-RA. The mean (range) cost per patient was £101.36 (£59.80-£132.20). Conclusions. Our data demonstrate that rTSA under ISB-RA is safe, cost-effective and a potentially viable alternative for patients with multiple comorbidities. Notably, patients with ASA grade 2 who underwent rTSA under ISB-RA had a reduced length of stay and were discharged within 24 hours

Aim: To assess the adequacy of reduction of Colles fracture by haematoma block and intravenous sedation and its outcome. Methodology: Retrospectively reviewed 70 Colles fracture reductions done in the A & E. 30 haematoma blocks and 40 intravenouss sedation. The prereduction radiographs were reviewed for the radial height & inclination and dorsal tilt. The outcome of the reduction was also reviewed. Results: The mean age was 59 years for haematoma block and 56 years for intravenous sedation. Fracture classifications were similar in both groups using the Frykman and Universal classification. The mean prereduction radial length, radial inclination and dorsal tilt were equal in both groups. There was significant difference in post reduction measurements between the two groups. 30% of the haematoma block group had further manipulation and K wiring done whereas only 15% of the intravenous sedation group had further procedures done. Conclusions: Our study showed that there was less remanipulation and better reduction in the intravenous group than the haematoma group. We recommend intravenous sedation as a preferred procedure for initial manipulation of Colles fratures for a better outcome

Displaced fractures of the distal radius in children are usually reduced under sedation or general anaesthesia to restore anatomical alignment before the limb is immobilized. However, there is growing evidence of the ability of the distal radius to remodel rapidly, raising doubts over the benefit to these children of restoring alignment. There is now clinical equipoise concerning whether or not young children with displaced distal radial fractures benefit from reduction, as they have the greatest ability to remodel. The Children’s Radius Acute Fracture Fixation Trial (CRAFFT), funded by the National Institute for Health and Care Research, aims to definitively answer this question and determine how best to manage severely displaced distal radial fractures in children aged up to ten years.

The last decade has seen a rise in the use of the gamma nail for managing inter-trochanteric and subtrochanteric hip fractures. Patients with multiple co-morbidities are under high anaesthetic risk of mortality and are usually not suitable for general or regional anaesthesia. However, there can be a strong case for fixing these fractures despite these risks. Apart from aiming to return patients to their pre-morbid mobility, other advantages include pain relief and reducing the complications of being bed bound (e.g. pressure ulcers, psychosocial factors). While operative use of local anaesthesia and sedation has been documented for insertion of extra-medullary femoral implants such as the sliding hip screw, currently no literature is present for the insertion of the gamma nail. We studied intra-operative and post-operative outcomes of three patients aged between 64 and 83 with right inter-trochanteric hip fractures and American Society of Anesthesiologists (ASA) scores of 4 or more. Consent for each case was obtained after discussion with the patient and family, or conducted with the patient's best interests in mind. All patients received a short unlocked gamma nail, and were operated on within 24 hours of admission. Each patient underwent local injections of Bupivacaine or Lignocaine or both, with Epinephrine, and with one patient receiving nerve block of the fascia iliaca. Each patient received a combination of sedatives under the discretion of the anaesthetist including Midazolam, Ketamine, Propofol, Fentanyl, and/or Haloperidol. Operating time ranged from 30–90 minutes. Patients were managed post-operatively with analgesia based on the WHO pain ladder and physiotherapy. Our results showed no intra-operative complications in any of the cases. All patients noted improvement in their pain and comfort post-operatively without complications of the operation site. Two patients achieved their pre-morbid level of mobility after undergoing physiotherapy and were subsequently discharged from the orthopaedic team. One patient with ongoing pre-operative medical complications died 5 days after the operation. This study provides a glimpse into the use of local anaesthetic and sedation on high operative risk patients, and this may be a viable alternative to extra-medullary implants or non-operation. Further research is needed to quantify the risks and benefits of operating within this patient group

Our aim was to assess the value of external fixation in pathological fractures in selected patients. During 2003–2008 we treated 35 patients with multiple myeloma or disseminated cancer, visceral metastases and pathological fractures with external fixation under sedation and local anaesthetic, because they were not fit for general anaesthesia. We used external fixation on 1 hip fracture, 1 fracture of the second metatarsal, 2 wrist fractures, 4 radial, 5 intertrochanteric, 1 subtro-chanteric, 12 fractures of the humerus, 1 ulna fracture, 4 femoral fractures, 3 tibial fractures and 1 femoral osteolysis. Operating times were 15–35 min, all patients were comfortable, cooperated well and they did not experience any pain during the procedure. In all cases XRT was applied either pre- or post-operatively. On follow up (2–48 months) 4 of the patients were deceased. Fracture stabilization was adequate and X-rays confirmed porosis in 4 fractures; however, two lesions expanded further, despite proper adjuvant bio-pharmaceutical therapy. 5 patients impoved so we could operate them later to treat the fractures definitively. All individuals experienced pain relief, they were adequately mobilized and most function was restored, while there was no major problem with pin tract infections. We suggest external fixation as a palliative treatment in patients with pathological fractures and multiple metastases, who don’t qualify for major surgery because of their critical illness. The later puts under local offer an excelent chance to fix fractures quikly, manage the pain and restore function without the risks of general anaesthesia

Aims. Manipulation under anaesthesia (MUA) remains an effective intervention to address restricted range of motion (ROM) after total knee arthroplasty (TKA) and occurs in 2% to 3% of primary TKAs at our institution. Since there are few data on the outcomes of MUA with different anaesthetic methods, we sought to compare the outcomes of patients undergoing MUA with intravenous (IV) sedation and neuraxial anaesthesia. Methods. We identified 548 MUAs after primary TKA (136 IV sedation, 412 neuraxial anaesthesia plus IV sedation) from March 2016 to July 2019. The mean age of this cohort was 62 years (35 to 88) with a mean body mass index of 31 kg/m. 2. (18 to 49). The mean time from primary TKA to MUA was 10.2 weeks (6.2 to 24.3). Pre-MUA ROM was similar between groups; overall mean pre-MUA extension was 4.2° (p = 0.452) and mean pre-MUA flexion was 77° (p = 0.372). We compared orthopaedic complications, visual analogue scale (VAS) pain scores, length of stay (LOS), and immediate and three-month follow-up knee ROM between these groups. Results. Following MUA, patients with IV sedation had higher mean VAS pain scores of 5.2 (SD 1.8) compared to 4.1 (SD = 1.5) in the neuraxial group (p < 0.001). The mean LOS was shorter in patients that received IV sedation (9.5 hours (4 to 31)) compared to neuraxial anaesthesia (11.9 hours (4 to 51)) (p = 0.009), but an unexpected overnight stay was similar in each group (8.6%). Immediate-post MUA ROM was 1° to 121° in the IV sedation group and 0.9° to 123° in the neuraxial group (p = 0.313). Three-month follow-up ROM was 2° to 108° in the IV sedation group and 1.9° to 110° in the neuraxial anaesthesia group (p = 0.325) with a mean loss of 13° (ranging from 5° gain to 60° loss), in both groups by three months. No patients in either group sustained a complication. Conclusion. IV sedation alone and neuraxial anaesthesia are both effective anaesthetic methods for MUA after primary TKA. Surgeons and anaesthetists should offer these anaesthetic techniques to match patient-specific needs as the orthopaedic outcomes are similar. Also, patients should be counselled that ROM following MUA may decrease over time. Cite this article: Bone Joint J 2021;103-B(6 Supple A):126–130

At-home softcast removal with no routine clinical follow-up has shown to be safe and effective following paediatric orthopaedic trauma. It minimises clinician contact time and reduces cost. However, there is limited data on the caregiver experience. Retrospective analysis of paediatric fractures requiring application of circumferential softcast that was later removed at home. Two time points were included: (1)July–September 2022, (2)February–April 2023. Demographics data included age, fracture classification, angulation, manipulation requirement, complications or unplanned re-attendance. Caregivers were given an information leaflet on cast removal. Caregivers completed a telephone Likert questionnaire reviewing time taken to remove cast, qualitative descriptors of cast removal and overall satisfaction. 77 families were contacted at mean 93 days post injury. Mean age was 7.5 years. 41(53%) were distal radius and 20(26%) both-bone forearm fractures. The remaining were hand, elbow or tibia injuries. 40(52%) injuries required manipulation under procedural sedation with mean sagittal angulation 24 degrees. 13(17%) patients re-attended with cast problems. Caregivers estimated a mean 13 minutes to remove cast. 83% found it ‘extremely’ or ‘somewhat’ easy. 75% were ‘extremely’ or ‘somewhat’ satisfied. 71% were ‘extremely’ or ‘somewhat’ likely to recommend at-home cast removal. Qualitative descriptors ranged from from ‘traumatising’ to ‘fun’ and ‘straightforward’. The experience at our tertiary centre confirms at-home softcast removal with no further orthopaedic follow-up is safe and feasible, even in those requiring manipulation under sedation. The majority of families reported a positive experience; this however is not universal. Adequate patient information resources are integral to a positive caregiver's experiences

Introduction. External fixation (EF) devices are commonly used in the management of complex skeletal trauma, as well as in elective limb reconstruction surgery for the management of congenital and acquired pathology. The subsequent removal of an EF is commonly performed under a general anaesthetic in an operating theatre. This practice is resource intensive and limits the amount of operating theatre time available for other surgical cases. We aimed to assess the use of regional anaesthesia as an alternative method of analgesia to facilitate EF removal in an outpatient setting. Materials & Methods. This prospective case series evaluated the first 20 consecutive cases of EF removal in the outpatient clinic between 10/06/22 to 16/09/22. Regional anaesthesia using ultrasound-guided blockade of peripheral nerves was administered using 1% lidocaine due to its rapid onset and short half-life. Patients were assessed for additional analgesia requirement, asked to evaluate their experience and perceived pain using the Visual Analogue Scale (VAS). Results. Twenty patients were included in the study. The mean age was 46.6 years (range 21–85 years). Two thirds were male patients (N=13). Post procedure all patients indicated positive satisfaction ratings, each participant responding as either ‘satisfied’ (N=4), ‘very satisfied’ (N=15) or ‘highly satisfied’ (N=1). In addition, 85% of participants reported they would opt for this method of EF removal in future should it be necessary. VAS for pain immediately following completion of the procedure was low, with an average score of 0.45 (range 0–4), where a score of 0= ‘No pain’, and 10 = ‘worst pain possible’. Conclusions. We present the first description of outpatient EF removal using sole regional anaesthesia, with a prospective case series of 20 EF removed in fully awake patients. This novel technique is cost-effective, reproducible, and safe. This not only reduces the burden of these surgical cases on an operating list but also improves patient experience when compared to other forms of conscious sedation. By eliminating the use of Entonox and methoxyflurane for sedation and analgesia, this project demonstrates a method of improving environmental sustainability of surgery, anaesthesia and operating theatres

Botulinum toxin A (BoNT-A) is a substance that requires repeated application due to its effectiveness being lost 12–16 weeks post application. Performing these intra-muscular injections under anesthesia reduces pain and distress during applications, ensuring effective and successful functional results. This study evaluates motor development of patients undergoing 3 or more repeated BoNT-A application in a tertiary pediatric hospital and the safety as well as effect of 3 different types of anesthesia. 75 children with cerebral palsy who underwent BoNT-A application at least three times consecutively with 6-month intervals and a total of 320 procedures admitted between January 2008 and January 2018 were retrospectively examined. Gross Motor Function Classification System (GMFCS) was employed in motor development evaluation. To observe the improvement in motor development, those with 2-1-0 level decreases in GMFCS classes were grouped and compared in terms of birth time, birth weight, cerebral palsy type and first BoNT-A application age. The 3 types of anesthesia methods (sedation analgesia, larengeal mask anesthesia (LMA) and inhalation mask anesthesia) applied during the procedures were compared in terms of sedation, procedure, recovery and total operation room time. The mean age of the children for all procedures was 45.51 ± 22.40 months. As a result of procedures, significant motor development was observed in 60 (80%) patients (p <0,000∗). No significant difference was observed when the children with cerebral palsy whose GMFCS declined in the form of level 2, 1 and unchanged were compared in terms of first application age, birth weight and gestational age. It was found that 106 (33.1%) were applied sevoflurane with anesthesia mask, 103 (32.1%) were administered sevoflurane with laryngeal mask, and 111 (34.6%) were sedation-analgesia. Only 10 out of 320 procedures were seen to develop side effects (8 vomiting, 2 bronchospasm). In the patients who underwent sedation analgesia during the first 3 BoNT-A procedures, the duration of recovery and total operating room time was seen to be significantly shorter than the others, while there was no difference between the anesthesia methods in the 4th and subsequent procedures. Regardless of the type of anesthesia, the recovery and total operating room times of those having undergone 6 or more procedures were longer than those with less than 6 procedures (p <0.009, p <0.016, respectively). As conclusion, repeated BoNT-A applications in children with CP provides progress in motor steps, it can be applied safely and effectively under anesthesia. Sedation analgesia application provides easier recovery compared to general anesthesia with LMA and mask only in the first three applications. However, recovery time increases with 4 and more repeated applications as the number of applications increases

Purpose. To assess outcomes of manipulating upper extremity fractures with conscious sedation compared with formal reduction and casting in theatre under general anaesthesia and image intensifier control. Method. Prospective six month period all patients presenting to the Emergency Department with a both bone forearm or distal radial fracture that was deemed suitable for closed reduction and casting where included in the study. All fractures deemed to require instrumentation were excluded. Results. We identified 56 fractures, 13 of the distal radius and 43 both bone forearm. 22 where treated in theatre with 34 treated in ED. Age range 2–14 years. We had 1 re fracture in the ED group and 1 re fracture in the theatre group. All fractures united within acceptable limits. We had no re operations in either group. No complications from the procedural sedation or anaesthesia. Mean time to treatment in theatre group was 18 hours Vs 3 hours in the ED group (P< 0.05). Conclusion. The use of procedural sedation, closed reduction and casting has no adverse effects on union, malunion, reoperation or anaesthetic complications. It is however significantly quicker, significantly lower in cost when compared with admission and treatment in theatre and has less negative psychological impact on the child. We recommend treatment in Emergency Department for all fractures of the forearm and distal radius that can be managed by closed reduction and casting in children who are safe to undergo procedural sedation

Glenohumeral dislocation is complicated with a greater tuberosity fracture in 16% of cases. Debate regarding the safety of closed reduction in the emergency department exists, with concerns over fracture propagation during the reduction manoeuvre. The study aim was to report the results of closed reduction, identify complications and define outcome for these injuries. 188 consecutive glenohumeral dislocations with a tuberosity fracture were identified from a prospective database from 2014–2017. 182 had an attempted closed reduction under appropriate sedation using standard techniques, five were manipulated in theatre due to contra-indications to sedation. Clinical, radiographic and patient reported outcomes, in the form of the QuickDASH and Oxford Shoulder Score (OSS), were collected. A closed reduction in the emergency department was successful in 162 (86%) patients. Two iatrogenic fractures of the proximal humerus occurred, one in the emergency department and one in theatre, representing a 1% risk. 35 (19%) of patients presented with a nerve lesion due to dislocation. Surgery was performed in 19 (10%) cases for persistent or early displacement (< 2 weeks) of the greater tuberosity fragment. Surgery resulted in QuickDASH and OSS scores comparable to those patients in whom the tuberosity healed spontaneously in an anatomical position (p=0.13). 18 patients developed adhesive capsulitis (10%). Glenohumeral dislocation with greater tuberosity fracture can be safely treated by closed reduction within the emergency department with a low risk of humeral neck fracture. Persistent or early displacement of the tuberosity fragment will occur in 10% of cases and is an indication for surgery

Aim: To examine the efficacy and ease of use of the scapular manipulation method in the reduction of anterior shoulder dislocations and the need for sedation/analgesia that usually requires prolonged observation of the patient after reduction. Method: This was a prospective series over six months. All patients presenting to the Waikato Hospital Emergency Department with uncomplicated anterior shoulder dislocations were included in the study. Reduction was firstly attempted with the Scapular Manipulation Method without analgesia or sedation. Where this was unsuccessful, analgesia and/or sedation was given and their shoulders reduced by one of various methods. The patients who received sedation were then observed as required. Results: Thirty-five patients with anterior shoulder dislocations were seen. In 30 cases the scapular manipulation method of reduction was used with a success rate of more than 80%. The need for sedation/analgesia that would usually lead to a period of observation was greatly reduced. Conclusion: The scapular manipulation method of reduction of anterior shoulder dislocation is an easy and safe technique with a success rate, and it obviates the need for prolonged patient observation

Purpose: The purpose of this prospective work was to determine: 1) the frequency of iliopsoas conflicts with prosthetic acetabular material in patients with a painful total hip arthroplasty, and 2) to determine the diagnostic features of this conflict and the results of an adapted therapeutic approach. Material and methods: This prospective study was conducted between 1988 and 2000 in 206 painful total hip arthroplasties. Nine patients (4.%), mean age 50 years (38–65) had a highly suggestive clinical presentation (eight press-fit cups without cement, one metal-backed cemented cup). Mean delay to onset after implantation of the total hip arthroplasty was 7.3 months (1–48). The predominant clinical sign was groin pain triggered by active flexion of the hip with pain from 3° to 70°. For these nine patients, there was no sign of loosening and puncture had ruled out infection. The diagnosis was confirmed by sedation of the pain after extra-articular infiltration in contact with the anterior acetabular rim (rim overhang in six out of nine cases) under computed tomographic guidance. Results: Therapeutic infiltration (xylocaine-slow release corticosteroids) under computed tomographic guidance provided complete sedation in four out of nine cases and partial sedation in one. Four patients experienced recurrence leading to terminal tenotomy of the iliopsoas which provided complete sedation in three and partial sedation in one. In all, seven of the nine patients achieved complete pain relief (four after infiltration including one recurrent case, and three after tenotomy). Physical examination at last follow-up did not disclose any loss of flexion amplitude of the thigh. Discussion and conclusion: The delay to symptom onset was variable, but a symptom-free interval was always observed after implantation of the total hip arthroplasty. An anatomic factor (anterior cup rim) was not indispensable for diagnosis as it was confirmed in one of three cases with a positive infiltration test without rim overhang. The infiltration test was essential to confirm diagnosis and constituted the first therapeutic attempt which allowed complete cure in four of the nine patients. Tenotomy, indicated in case of recurrence, achieved complete cure in three of the four cases. The cup does not have to be changed necessarily to treat iliopsoas conflicts since infiltration or simple tenotomy provided complete cure in seven out of nine cases

Introduction: Many minor procedures are performed daily in fracture clinic and often carried out under intravenous sedation and analgesia. These occur between 9 am and 8 pm. Methods: All minor and intermediate cases logged in the theatre register at the fracture clinic were reviewed from February 2007 to February 2008. The following items were recorded: month, age of patient, diagnosis, procedure, grade of doctor or nurse performing the procedure and the method of anaesthesia and the time of day the procedure was carried out. Specifically the use of intravenous sedation, intravenous morphine, use of Entonox, and local or regional anaesthetic techniques were recorded. Records were classified by the time of day the procedure occurred – any procedure starting at or after 1730 hours was regarded as an ‘out-of-hours’ procedure. Results: The age range of patients undergoing procedures ranged from 13 to 100 years, with a mean age of 49 years. 576 procedures were performed, 529 by SHOs, 35 by registrars, 4 by consultants and 8 by nursing staff. The commonest procedure was distal radius manipulation under anaesthesia (MUA) with 227 cases, followed by ankles with 175 cases. Intravenous sedation was used in 473 cases with 95 of these occurring ‘out-of-hours’. Entonox was used in 33 cases. A regional or local anaesthetic technique was used in 38 cases. No anaesthetic or analgesia was required in 10 cases. Discussion: The ability to perform minor and intermediate procedures is dependent on being to provide safe and appropriate anaesthesia. If the current procedures could not be performed in fracture clinic this would put significant pressures on operating theatre time and would have inherent cost implications. However, in order to provide safe and appropriate anaesthesia for these procedures adequate and contempory staff training is required, especially when intravenous sedation is utilised

Aim. In our Bone Infection Unit, epidural anaesthesia and sedation (EA+Sed) is the technique of choice for complex orthoplastic surgery involving lower limb free tissue transfer (LLFTT) (1) as it avoids complications of prolonged general anaesthesia (GA). Following our initial reports of successful use of audio-visual distraction (AVD) as an adjunct to regional anaesthesia we wished to evaluate the AVD effect on the patients’ experience during long duration, complex orthoplastic surgery for chronic osteomyelitis under EA+Sed. Method. Our AVD equipment consists of a WiFi connected tablet and noise reducing head phones, providing access to downloaded music, films and the internet. Patients are also allowed to use their own equipment. All patients were fully informed about AVD and EA+Sed as a choice of anaesthesia. EA was established in the anaesthetic room and continued perioperatively. Sedation with propofol was titrated to the patients’ requirements to ensure comfort during surgery. All patients were followed up postoperatively with a structured questionnaire. Results. Ten patients underwent LLFTT surgery for chronic bone infection under EA+Sed+AVD (picture). Mean duration of surgery was 550 min (480 −600 min). Patients used the AVD to listen to music, watch movies, play internet games and use e-mail and social media. All 10 patients were very satisfied, and 9 reported feeling comfortable or very comfortable intraoperatively. All rated their experience better than previous GAs, with quicker general recovery. All patients would recommend this technique to others. Conclusions. Our case series of patients undergoing prolonged surgery for osteomyelitis under EA+Sed has shown very positive impact of AVD on patients’ experience and confirmed our earlier encouraging observations. This clinical service improvement deserves further evaluation and funding

Summary. Timing for the application and use of fentanyl patches for pre-emptive analgesia and sedation is crucial to obtain good clinical outcomes. Placement and timing is important to maximise clinical effect and apparent levels of analgesia. Introduction. The use of sheep as preclinical models for the investigation of orthopaedic conditions is gaining momentum, the control of their pain is a significant ethical issue. The daily need for injecting non-steroidal anti-inflammatory drugs (NSAIDs) and/or the shorter acting opioids increases the demand for handling post-operatively which can increase animal distress and risk of human injury. NSAIDs can have a negative effect on bone healing, complicating results. Opioid analgesics have no impact on bone healing. Fentanyl patches have become another option for use in pain management. Pre-emptive analgesia helps reduce the demand on post-operative analgesic use. Fentanyl has the added benefit of producing mild sedation. This study evaluated the pharmacokinetics of fentanyl patches in sheep in an effort to maximise pre and post-surgical analgesia. Methods. Eight sheep were divided into 2 groups of 4. Both groups had a 100µg/kg/hr fentanyl patch (Durogesic – Janssen, Sydney, Australia) applied to the clipped and cleaned skin of the antebrachium and were held in place with a light bandage. (A dose rate range of 1- 1.6µg/kg/hr was achieved). Group 1 had a second patch applied after 72 hours and group 2 had a second patch applied after 24 hours. Blood samples were taken at 0, 3, 6, 12, 24, 36, 48 and 72 hours post patch application. The blood was immediately spun down and the serum drawn off and frozen. Serum levels for fentanyl were measured using commercial ELISA kits and read using a spectrophotometer. Animal behaviour throughout the study was observed and recorded by trained staff (CC, JR). Results. Six hours after the patch application, the sheep were relaxed and easily approachable. They stood calmly while blood was being drawn. This behaviour remained up to the 48 hour time point at which time cornering them in their pen became marginally more difficult, however they still stood calmly for the blood collection. By 72 hours, all sheep co-operation had dissipated. Peak blood levels of Fentanyl were reached by 12 hours post patch application. These levels were maintained with a relatively flat drug plateau for the prescribed 72 hours post application. No difference was found in the peak drug levels post application of the second patch between the two groups. There was no second higher peak in blood levels attained. Discussion. This study quantified the drug absorption and elimination curves of fentanyl using a controlled application method in an effort to better apply and manage post-surgical analgesia in sheep used for orthopaedic studies. The results indicate that the application of fentanyl for pre-emptive surgical analgesia can be applied for the full duration of 72 hours prior to the application of the second patch at the time of surgery. No benefit regarding analgesia appears to be gained from changing the first patch after 24 hours as peak serum levels are not affected. However for peak sedation the second patch can be applied anytime from 6 to 48 hours. This analgesic regime is beneficial to the animal as well as its handling and management
