Traumatic Native Hip Dislocations: An Audit at a Major Trauma Centre and Assessment of Clinical Practice at Centres Across the United Kingdom.

INTRODUCTION: Native hip dislocations are defined as traumatic dislocations of the hip, typically high-energy and associated with polytrauma. The majority of these injuries occur following motor vehicle accidents (MVAs). Due to the inherent stability of the hip joint, a significant force is required to cause dislocation. It is critical that such injuries are managed and reduced in a timely manner. We evaluated the current practice in a major trauma centre (MTC) in Cardiff and gathered information from emergency departments (EDs) in Wales and MTCs around the United Kingdom (UK). METHODS: We did an evaluation of the current practice with a retrospective audit of all traumatic native hip dislocations presenting to the MTC at Cardiff from August 2018 to February 2021. Data was obtained from Trauma Audit and Research Network (TARN), medical records, radiology and theatre management systems. An online survey was developed and disseminated to EDs in Wales and MTCs across the UK. RESULTS: There were 15 traumatic hip dislocation cases over the period evaluated. Sixty percent of cases were due to MVA. Eighty-six percent of patients had an associated fracture, with one Pipkin type IV fracture dislocation. The mean time to reduction from injury was 532 minutes (240-804 minutes), with 28.6% reduced within 6 hours and 71.4% reduced within 12 hours. Two patients had reduction performed in the ED (mean time to reduction, 275 minutes). There was one occurrence of avascular necrosis (AVN) and one of chondrolysis at the follow-up. The response rate to the survey was 80% and 83% in Wales and MTCs nationally, respectively. The majority (82%) of departments did not have an established pathway in place for managing traumatic native hip dislocations with a preference for reduction in the operating theatre. CONCLUSION: Native hip dislocations are rare, high-energy injuries associated with significant morbidity. The available evidence suggests time to reduction is imperative in reducing the risk of future complications. The establishment of a pathway to guide management and having a mechanism to perform reductions in the ED may produce significant reductions in this time, impacting outcomes.

Hydroxyapatite-Coated Screws Versus Titanium Triangular Dowels for Sacroiliac Joint Fusion: Results From a Nonrandomized Prospective Outcome Study.

OBJECTIVE: This is a single-surgeon series that prospectively evaluates the results of sacroiliac joint (SIJ) fusion for patients with SIJ dysfunction using hydroxyapatite-coated screws (HACSs) compared with titanium triangular dowels (TTDs). METHODS: A total of 113 patients underwent SIJ fusion surgery between 2013 and 2018 at the University Hospital Llandough to treat symptomatic SIJ dysfunction not responding to nonoperative measures. Of the 113 patients, 40 were treated with HACSs and 73 with TTDs. Patient-reported outcomes measures (PROMs) were collected preoperatively and at 12 months postoperatively, including the 36-item short-form health survey, Oswestry disability index, EuroQol-5D-5L, and Majeed pelvic score. Patients with ongoing symptoms were followed up beyond the study period. RESULTS: Of the 113 patients, 33 completed follow-up in the HACS group compared with 61 in the TTD group. Both groups had comparable preoperative PROMs; however, the postoperative PROMs were significantly better in the TTD group. Additionally, 21 patients (63%) in the HACS group had radiological evidence of screw lysis compared with 5 patients (9%) in the TTD group. A subgroup analysis revealed less significant improvement in PROMs for patients with screw lysis compared with those without. Four patients were offered further revision surgery. CONCLUSIONS: Minimally invasive SIJ fusion has been shown to have good clinical outcomes for select patients. However, our experience shows that HACSs are associated with a high rate of screw lysis and poorer patient outcomes compared with TTDs. Therefore, we recommend the use of TTDs instead of HACSs for SIJ fusion surgery.

Radiological outcomes following surgical fixation with wires versus moulded cast for patients with a dorsally displaced fracture of the distal radius: a radiographic analysis from the DRAFFT2 trial.

Aims: The primary aim of this study was to report the radiological outcomes of patients with a dorsally displaced distal radius fracture who were randomized to a moulded cast or surgical fixation with wires following manipulation and closed reduction of their fracture. The secondary aim was to correlate radiological outcomes with patient-reported outcome measures (PROMs) in the year following injury. Methods: Participants were recruited as part of DRAFFT2, a UK multicentre clinical trial. Participants were aged 16 years or over with a dorsally displaced distal radius fracture, and were eligible for the trial if they needed a manipulation of their fracture, as recommended by their treating surgeon. Participants were randomly allocated on a 1:1 ratio to moulded cast or Kirschner wires after manipulation of the fracture in the operating theatre. Standard posteroanterior and lateral radiographs were performed in the radiology department of participating centres at the time of the patient's initial assessment in the emergency department and six weeks postoperatively. Intraoperative fluoroscopic images taken at the time of fracture reduction were also assessed. Results: Patients treated with surgical fixation with wires had less dorsal angulation of the radius versus those treated in a moulded cast at six weeks after manipulation of the fracture; the mean difference of -4.13° was statistically significant (95% confidence interval 5.82 to -2.45). There was no evidence of a difference in radial shortening. However, there was no correlation between these radiological measurements and PROMs at any timepoint in the 12 months post-injury. Conclusion: For patients with a dorsally displaced distal radius fracture treated with a closed manipulation, surgical fixation with wires leads to less dorsal angulation on radiographs at six weeks compared with patients treated in a moulded plaster cast alone. However, the difference in dorsal angulation was small and did not correlate with patient-reported pain and function.

Results From an All Wales Trainee Led Collaborative Prospective Audit on Management of Ankle Fractures.

Aim The purpose of this all Wales national audit was to compare compliance against British Orthopedic Association Standards for Trauma (BOAST) guidelines on the management of ankle fractures. Methods A multi-center prospective audit of the management of adult ankle fractures was conducted between February 2, 2020, and February 17, 2020, via the Welsh Orthopedic Research Collaborative (WORC). Regional leads were recruited in nine NHS hospitals across six university health boards, and recruited collaborators in their respective hospitals. Questionnaires for the data collection on both surgical and conservative management were made available via a password-protected website (walesortho.co.uk). We defined early weight-bearing (EWB) as unrestricted weight-bearing on the affected leg within three weeks of injury or surgery and delayed weight-bearing (DWB) as unrestricted weight-bearing after three weeks of injury or surgery. Results A total of 28 collaborators contributed data for 238 ankle fractures. Poor documentation at the time of injury was noted. Less than 50% of patients with posterior malleolus fracture had a CT scan for further evaluation. Eighty-four percent of the non-operatively treated patients did not have a weight-bearing X-ray (WBXR). Patients who had a WBXR were more likely to be allowed EWB but this was not statistically significant. EWB was allowed in 59.43% and 10% of the non-operatively and operatively treated patients, respectively. DWB was higher in patients who had fixation of the posterior malleolus or syndesmosis. Conclusion There is poor compliance with BOAST guidelines on the management of ankle fractures across Wales. We need to improve documentation and also consider performing a CT scan when the posterior malleolus is fractured. A weight-bearing X-ray should be performed more often to ascertain the stability of an ankle fracture, and those that are deemed stable should be treated with early weight-bearing. The guidelines need to be clearer regarding weight-bearing after fixation especially when posterior malleolus and/or syndesmosis are fixed.

Trainee Principal Investigator Could Improve Recruitment in Trauma Trials: Review of Literature and Experience From a Trauma Center.

INTRODUCTION: Recruitment of patients to participate in randomized control trials (RCT) is a challenging task, especially for trauma trials in which the identification and recruitment are time-limited. Multiple strategies have been tried to improve the participation of doctors and the recruitment of patients. The aim was to study the effect of a trainee principal investigator (TPI) on the efficacy of recruitment for a multicenter hip fracture RCT. METHODS: A retrospective study comparing the number of junior doctors participating in the WHiTE 8 COPAL RCT and patients recruited before and after the introduction of formal TPI role at a major trauma center in the UK. Data was collected for nine months "before" (Nov 2018-July 2019) and six months "after" (Sept 2019-Feb 2020) the role of TPI was assigned. RESULTS: From November 2018 to February 2020, a total of 292 patients were eligible for recruitment into this trial, out of which 196 (67.12 %) were successfully recruited. Excluding the research team, there were seven junior doctors actively recruiting in the "before period" in comparison with 10 in the "after period." Significantly more patients were recruited by junior doctors after a TPI was assigned. Overall, more percentage of eligible patients were recruited into the trial after a TPI was assigned, and this was statistically significant. CONCLUSION: The allocation of a formal TPI significantly improved the recruitment of patients in a national RCT. TPI can work alongside the principal investigator and research team to be a valuable link person coordinating and engaging local trainees to take part in trials.

The Patient Experience of Inpatient Care During the COVID-19 Pandemic: Exploring Patient Perceptions, Communication, and Quality of Care at a University Teaching Hospital in the United Kingdom.

The coronavirus disease 2019 (COVID-19) pandemic has necessitated many rapid changes in the provision and delivery of health care in hospital. This study aimed to explore the patient experience of inpatient care during COVID-19 pandemic. An electronic questionnaire was designed and distributed to inpatients treated at a large University Health Board over a 6-week period. It focused on hospital inpatients' experience of being cared for by health care professionals wearing personal protective equipment (PPE), explored communication, and patients' perceptions of the quality of care. A total of 704 patients completed the survey. Results demonstrated that patients believe PPE is important to protect the health of both patients and staff and does not negatively impact on their care. In spite of routine use of PPE, patients were still able to identify and communicate with staff. Although visiting restrictions were enforced to limit disease transmission, patients maintained contact with their relatives by using various electronic forms of communication. Overall, patients rated the quality of care they received at 9/10. This single-center study demonstrates a positive patient experience of care at an unprecedented time.

Are Hydroxyapatite-Coated Screws a Good Option for Sacroiliac Joint Stabilization? A Prospective Outcome Study.

OBJECTIVE: This is a single-surgeon series to prospectively evaluate the clinical and radiologic results of sacroiliac joint (SIJ) stabilization using hydroxyapatite (HA)-coated, fully threaded screws in patients with SIJ dysfunction. METHODS: A total number of 40 patients underwent percutaneous SIJ stabilization using HA-coated screws between 2013 and 2015 at the University Hospital of LLandough with an age range of 33-84 years. Patients were followed up closely, and outcome scores were collected preoperative and 12 months after surgery. Preoperative and postoperative outcomes were evaluated using patient-reported outcome measures (PROMs), Short Form-36, Oswestry Disability Index, EuroQol-5D-5L, and Majeed Pelvic Scores. RESULTS: Thirty-three patients (8 male and 32 female) out of the 40 patients completed follow-up. There was an overall improvement in all PROMs; however, only mental component of SF-36, Oswestry Disability Index, Majeed Pelvic Scores, and EuroQol-5D-5L were statistically significant. Twenty-one patients (63%) had lysis around the screw, and a subgroup analysis showed that improvement in PROMs was significantly less in patients with lysis around the screw. Four patients with lysis around the screw were offered revision due to ongoing pain. Revision was successful in only 1 patient. CONCLUSIONS: Percutaneous SIJ fixation procedure has been shown to have good clinical outcomes, but the use of HA-coated fully threaded screws in this procedure is not recommended on the basis of patient-reported outcome measures and radiologic findings in this prospective study.

The role of orthopaedic trainees during the COVID-19 pandemic and impact on post-graduate orthopaedic education: a four-nation survey of over 100 orthopaedic trainees.

AIMS: The COVID-19 pandemic has had a significant impact on the provision of orthopaedic care across the UK. During the pandemic orthopaedic specialist registrars were redeployed to "frontline" specialties occupying non-surgical roles. The impact of the COVID-19 pandemic on orthopaedic training in the UK is unknown. This paper sought to examine the role of orthopaedic trainees during the COVID-19 and the impact of COVID-19 pandemic on postgraduate orthopaedic education. METHODS: A 42-point questionnaire was designed, validated, and disseminated via e-mail and an instant-messaging platform. RESULTS: A total of 101 orthopaedic trainees, representing the four nations (Wales, England, Scotland, and Northern Ireland), completed the questionnaire. Overall, 23.1% (23/101) of trainees were redeployed to non-surgical roles. Of these, 73% (17/23) were redeployed to intensive treatment units (ITUs), 13% (3/23) to A/E, and 13%(3/23%) to general medicine. Of the trainees redeployed to ITU 100%, (17/17) received formal induction. Non-deployed or returning trainees had a significant reduction in sessions. In total, 42.9% (42/101) % of trainees were not timetabled into fracture clinic, 53% (53/101) of trainees had one allocated theatre list per week, and 63.8%(64/101) of trainees did not feel they obtained enough experience in the attached subspecialty and preferred repeating this. Overall, 93% (93/101) of respondents attended at least one weekly online webinar, with 79% (79/101) of trainees rating these as useful or very useful, while 95% (95/101) trainees attended online deanery teaching which was rated as more useful than online webinars (p = 0.005). CONCLUSION: Orthopaedic specialist trainees occupied an important role during the COVID-19 pandemic. COVID-19 has had a significant impact on orthopaedic training. It is imperative this is properly understood to ensure orthopaedic specialist trainees achieve competencies set out in the training curriculum.Cite this article: Bone Joint Open 2020;1-11:676-682.

Personal protective equipment during the COVID-19 crisis: a snapshot and recommendations from the frontline of a university teaching hospital.

AIMS: The adequate provision of personal protective equipment (PPE) for healthcare workers has come under considerable scrutiny during the COVID-19 pandemic. This study aimed to evaluate staff awareness of PPE guidance, perceptions of PPE measures, and concerns regarding PPE use while caring for COVID-19 patients. In addition, responses of doctors, nurses, and other healthcare professionals (OHCPs) were compared. METHODS: The inclusion criteria were all staff working in clinical areas of the hospital. Staff were invited to take part using a link to an online questionnaire advertised by email, posters displayed in clinical areas, and social media. Questions grouped into the three key themes - staff awareness, perceptions, and concerns - were answered using a five-point Likert scale. The Kruskal-Wallis test was used to compare results across all three groups of staff. RESULTS: Overall, 315 staff took part in our study. There was a high awareness of PPE guidance at 84.4%, but only 52.4% of staff reported adequate PPE provision. 67.9% were still keen to come to work, despite very high levels of anxiety relating to contracting COVID-19 despite wearing PPE. Doctors had significantly higher ratings for questions relating to PPE awareness compared to other staff groups, while nursing staff and OHCPs had significantly higher levels of anxiety compared to doctors in relation to PPE and contracting COVID-19 (p < 0.05 using a Kruskal-Wallis test). CONCLUSION: We believe four recommendations are key to improve PPE measures and decrease anxiety: 1) nominated ward/department PPE champions; 2) anonymized reporting for PPE concerns; 3) formal PPE education sessions; and 4) drop-in counselling sessions for staff. We hope the insight and recommendations from this study can improve the PPE situation and maintain the health and wellbeing of the clinical work force, in order to care for COVID-19 patients safely and effectively.

COVID-19 and orthopaedic surgery: evolving strategies and early experience.

AIMS: COVID-19 has changed the practice of orthopaedics across the globe. The medical workforce has dealt with this outbreak with varying strategies and adaptations, which are relevant to its field and to the region. As one of the 'hotspots' in the UK , the surgical branch of trauma and orthopaedics need strategies to adapt to the ever-changing landscape of COVID-19. METHODS: Adapting to the crisis locally involved five operational elements: 1) triaging and workflow of orthopaedic patients; 2) operation theatre feasibility and functioning; 3) conservation of human resources and management of workforce in the department; 4) speciality training and progression; and 5) developing an exit strategy to resume elective work. Two hospitals under our trust were redesignated based on the treatment of COVID-19 patients. Registrar/consultant led telehealth reviews were carried out for early postoperative patients. Workflows for the management of outpatient care and inpatient care were created. We looked into the development of a dedicated operating space to perform the emergency orthopaedic surgeries without symptoms of COVID-19. Between March 23 and April 23, 2020, we have surgically treated 133 patients across both our hospitals in our trust. This mainly included hip fractures and fractures/infection affecting the hand. CONCLUSION: The COVID-19 pandemic is not the first disease outbreak affecting the UK, nor will it be the last. The current crisis has necessitated rapid development of new hospital guidelines and early adaptive strategies in our services. Protocols and directives need to be formalized keeping in mind that COVID-19 will have a long and protracted course until a definitive cure is discovered.

Fixation of periprosthetic or osteoporotic distal femoral fractures with locking plates: a pilot randomised controlled trial.

INTRODUCTION: We hypothesised that the use of a polyaxial locking plate design offers the same clinical benefits as a monoaxial locking plate system following distal femoral osteoporotic/periprosthetic fracture fixation. METHOD: A multicentre prospective randomised pilot trial was conducted. Inclusion criteria were patients over 60 years with a displaced osteoporotic or periprosthetic distal femoral fracture. Details documented included time to union, complications, reinterventions and functional outcomes according to the Oxford knee score and EuroQol EQ-5D. Analysis of factors influencing an early fracture healing response was performed between those with clear features of radiological callus formation at three months. Statistical analysis was performed using a logistic regression model with multiple covariates assessed for each plate system (1:1 ratio) over a follow-up period of one year. RESULTS: Forty patients (34 females) with a mean age of 77 (60-99) were recruited. Four patients deceased within the first six months. Twenty-five patients united by the six month follow-up. Six more patients progressed to union between six and nine months. Five patients developed non-union (two patients had implant failure; one in each group) and all underwent revision surgery. Malunion was evident in two cases, one with 15° of valgus (monoaxial plate), and one with 12° of recurvatum (polyaxial plate). Between the two plate systems, statistical analysis revealed no significant differences in most of the recorded parameters. Radiological features of early bone healing were present when the surgical approach was smaller (p = 0.015), and when a greater working length of the bridging plate was present (p = 0.016). CONCLUSION: Both plate systems demonstrated good union rates and limited implant related complications. Good reduction, mechanically sound construct and respect of the local fracture biology was more important than the particular plate design characteristics.

When is it safe to reduce fracture dislocation of shoulder under sedation? Proposed treatment algorithm.

INTRODUCTION: Shoulder dislocations are common. It is known that incongruent shoulder should be promptly reduced. However, when associated with fracture of the proximal humerus, there is a clinical dilemma if reduction under sedation is a safe option. We wanted to establish when it is safe to attempt reduction of a shoulder fracture dislocation under sedation in emergency room. METHODS: This is a retrospective cohort study assessing consecutive patients presenting with a dislocation of a gleno-humeral joint with an associated fracture of the humerus between 2007 and 2015. The radiographs and patients' records were examined. The number of fragments according to Neer's criteria and size of fragments were recorded. RESULTS: We identified 102 patients who presented with 104 cases of fracture dislocation of shoulder joint. 10 of the dislocations were posterior, remainder were anterior. All posterior dislocations were reduced under general anaesthesia. Sixty-two anterior fracture dislocations had attempted reduction under sedation in emergency department. Eight of those were unsuccessful, and patient required general anaesthetic for further management. In five of those cases, significant displacement of humeral head in relation to the shaft after attempted reduction. CONCLUSION: We propose pragmatic approach to the initial treatment of fracture dislocations of shoulder. In type I injury, where there is an anterior dislocation with greater tuberosity fracture, one should attempt a reduction under sedation; 94% of attempted reductions under sedation were successful and no fracture propagation occurred. In case of a type II injury, when the fracture is involving a surgical neck of the humerus with or without greater tuberosities fracture, our experience suggests that no attempt of reduction is undertaken under sedation and patient has general anaesthetic. Posterior dislocation with any fracture remains an unsolved problem, but in our series no attempt of reduction under sedation was made.

Psychometric properties including reliability, validity and responsiveness of the Majeed pelvic score in patients with chronic sacroiliac joint pain.

PURPOSE: The Majeed scoring system is a disease-specific outcome measure that was originally designed to assess pelvic injuries. The aim of this study was to determine the psychometric properties of the Majeed scoring system for chronic sacroiliac joint pain. METHODS: Internal consistency, content validity, criterion validity, construct validity and responsiveness to change was assessed prospectively for the Majeed scoring system in a cohort of 60 patients diagnosed with sacroiliac joint pain. This diagnosis was confirmed with CT-guided sacroiliac joint anaesthetic block. RESULTS: The overall Majeed score showed acceptable internal consistency (Cronbach alpha = 0.63). Similarly, it showed acceptable floor (0 %) and ceiling (0 %) effects. On the other hand, the domains of pain, work, sitting and sexual intercourse had high (>30 %) floor effects. Significant correlation with the physical component of the Short Form-36 (p = 0.005) and Oswestry disability index (p ≤ 0.001) was found indicating acceptable criterion validity. The overall Majeed score showed acceptable construct validity with all five developed hypotheses showing significance (p ≤ 0.05). The overall Majeed score showed acceptable responsiveness to change with a large (≥0.80) effect size and standardized response mean. CONCLUSION: Overall the Majeed scoring system demonstrated acceptable psychometric properties for outcome assessment in chronic sacroiliac joint pain. Thus, its use in this condition is adequate. However, some domains demonstrated suboptimal performance indicating that improvement might be achieved with the development of an outcome measure specific for sacroiliac joint dysfunction and degeneration.

Distal third humeri fractures treated using the Synthes™ 3.5-mm extra-articular distal humeral locking compression plate: clinical, radiographic and patient outcome scores.

BACKGROUND: Conventional management protocols for distal humeral extra-articular fractures (e.g. conservative, double columnar plating) are often associated with complications. We aimed to describe our experience of using the Synthes™ 3.5-mm extra-articular distal humeral locking compression plate for treatment of extra-articular distal humeral fractures. METHODS: We prospectively studied 23 consecutive patients who underwent fixation, in a tertiary trauma centre, over 2 years. Data, including patient demographics, duration of follow-up, patient satisfaction, visual analogue score (VAS), Oxford Elbow Score, and final outcome on discharge, were collected and analyzed. RESULTS: Of the 23 patients (12 males, 11 females; mean age 47.5 years; range 18 years to 89 years), all fractures united radiologically and clinically after the index procedure, with a mean time to fracture union of 15.7 weeks (range 9 weeks to 34 weeks) and a mean time to discharge of 17.8 weeks (range 13 weeks to 34 weeks). Oxford Elbow Score was 36.5 (range 11 to 48) at 4.6 months postoperatively; at 20 months follow-up, it was 40 (range 14 to 48) and the VAS was 8.5 (range 5 to 10). One patient had radial nerve neuropraxia pre-operatively, and one postoperatively, and both recovered uneventfully 3 months postoperatively. Neither superficial, nor deep infections were observed in this cohort. CONCLUSIONS: The present study reports satisfactory outcome with the usage of the Synthes plate for extra-articular fracture management. It has become the technique of choice in our centre because it provides excellent results.

Three-column classification and Schatzker classification: a three- and two-dimensional computed tomography characterisation and analysis of tibial plateau fractures.

OBJECTIVE: The aim of the study was to evaluate inter-observer reliability and intra-observer reproducibility between the three-column classification and Schatzker classification systems using 2D and 3D CT models. MATERIALS AND METHODS: Fifty-two consecutive patients with tibial plateau fractures were evaluated by five orthopaedic surgeons. All patients were classified into Schatzker and three-column classification systems using x-rays and 2D and 3D CT images. The inter-observer reliability was evaluated in the first round and the intra-observer reliability was determined during the second round 2 weeks later. RESULTS: The average intra-observer reproducibility for the three-column classification was from substantial to excellent in all sub classifications, as compared with Schatzker classification. The inter-observer kappa values increased from substantial to excellent in three-column classification and to moderate in Schatzker classification The average values for three-column classification for all the categories are as follows: (I-III) k2D = 0.718, 95% CI 0.554-0.864, p < 0.0001 and average 3D = 0.874, 95% CI 0.754-0.890, p < 0.0001. For Schatzker classification system, the average values for all six categories are as follows: (I-VI) k2D = 0.536, 95% CI 0.365-0.685, p < 0.0001 and average k3D = 0.552 95% CI 0.405-0.700, p < 0.0001. The values are statistically significant. CONCLUSION: Statistically significant inter-observer values in both rounds were noted with the three-column classification, making it statistically an excellent agreement. The intra-observer reproducibility for the three-column classification improved as compared with the Schatzker classification. The three-column classification seems to be an effective way to characterise and classify fractures of tibial plateau.

Management of Mason type 1 radial head fractures: a regional survey and a review of literature.

INTRODUCTION: Despite being the most common fracture around the elbow, the management of Mason type 1 radial head fractures lacks a clear protocol in literature. The aims of this study were to assess our practice of managing this injury and to create guidance for the management of these fractures based on literature review. METHODS: We designed a survey investigating the practice of orthopaedic surgeons in the management of Mason type 1 fracture. The literature review was carried out looking for the best practice guidelines. RESULTS: Forty-nine surgeons (out of 56) responded, and mean duration of immobilisation was 11.69 days with the collar and cuff sling as the preferred method. 65.3% offered physiotherapy service to their patients. 20.4% recommended plain radiographic imaging follow-up. Mean duration of follow-up was 43.9 days. Decision to discharge the patient was mostly (77.6%) dependent on clinical improvement at time of last examination. 4.1% of treatment decisions were evidence based. CONCLUSION: We observed a wide variation in the management of this common injury. Based on the current literature, the best protocol for the management of type 1 radial head fractures should be joint aspiration, followed by immobilisation in a broad arm sling for 2 days. At the first outpatient visit, assessment of the collateral stability should be performed. Patients with stable elbows should be encouraged to stretch these beyond the painful range. Patients can be discharged at this stage with an advice to come back for a clinical and radiographic assessment if there is no improvement at 6 weeks.

The percutaneous stabilisation of the sacroiliac joint with hollow modular anchorage screws: a prospective outcome study.

PURPOSE: The use of percutaneous iliosacral screw fixation as a treatment of sacroiliac joint pain has been reported to be successful. This study was a prospective single surgeon series to evaluate the short-term outcomes of patients who underwent percutaneous sacroiliac joint stabilisation. METHODS: Between July 2004 and February 2011, 73 patients underwent percutaneous sacroiliac joint fusion in our unit. All patients completed a short form (SF)-36 questionnaire, visual analogue pain score and Majeed scoring questionnaire prior to treatment and at last follow-up. RESULTS: 55 patients (9 male and 46 female) completed follow-up. The average follow-up period was for 36.18 months (range 12-84). The mean preoperative SF-36 scores were 26.59 for physical health and 40.38 for mental health. The mean postoperative SF-36 scores were 42.93 for physical health and 52.77 for mental health. The mean visual analogue pain scores were 8.1 preoperative and 4.5 postoperative. The mean pelvic specific scoring were 36.9 preoperative and 64.78 postoperative. We noted that patients who had previous instrumented spinal surgery did significantly worse than those who had not. We had two nerve root-related complications. CONCLUSION: We conclude that in selected patient group who respond positively to CT-guided injection, a percutaneous SI joint stabilisation is beneficial in effecting pain relief and functional improvement.

Patient estimates of healthcare costs in trauma and orthopaedics.

AIM: The cost of treating trauma and musculoskeletal conditions per head of population in Wales in 2007-2010 increased from £183 to £236, representing an increase in National Health Service total expenditure of 13.11 %. This study was set up to determine whether the public is aware of the general costs of treatment within the trauma and orthopaedic department. METHOD: Patients completed a questionnaire asking them what they thought the cost was for common orthopaedic treatments, investigations and implants. This questionnaire was completed whilst they were waiting to be seen in clinic. RESULTS: We had 183 completed questionnaires from patients with an average age of 43.47 years (range, 18-85 years). All patients were members of the public, with no previous experience of NHS work or costing. The inter-rater reliability was 0.39(95 % CI, 0.178-0.559). A product was accurately assessed if the estimates were between 50 and 200 % of the true cost. Costs of arm slings and crutches were well estimated by >80 % of the respondents. Approximately 60 % accurately estimated the cost of a fracture clinic visit, hospital transport and physiotherapy and lower limb plaster. Only 22.5 % accurately estimated the cost of a knee X-ray with 37.6 % overestimating the cost by more than tenfold. Other expenses that were underestimated by patients were the costs of a total hip replacement (in 58.3 %), fixation of an ankle fracture (in 32.2 %) and an overnight inpatient stay (in 10.9 %). CONCLUSION: Whilst the costs of physical products were well estimated by our cohort of patients, the costs of less tangible products, such as radiology and operations, were poorly estimated. Our study shows that there is a poor public perception of the true cost for investigation and operative treatment of common trauma and orthopaedic conditions.

The Correlation of Serum Metal Ions with Functional Outcome Scores at Three-to-Six Years following Large Head Metal-on-Metal Hip Arthroplasty.

Based on success of hip resurfacing, large head Metal on Metal (MoM) hip arthroplasty has gained significant popularity in recent years. There are growing concerns about metal ions related soft tissue abnormalities. The aim of this study was to define a correlation of metal ions with various functional outcome scores following large head MoM hip arthroplasty. Consecutive cohort of 70 patients (76 hips) with large head MoM hip arthroplasty using SL-Plus femoral stem and Cormet acetabular component were prospectively followed up. An independent observer assessed the patients which included serology for metal ion levels and collection of Oxford Hip, Harris hip, WOMAC, SF-36 & modified UCLA scores. Median serum cobalt and chromium levels were 3.10 µg/L (0.35-62.92) and 4.21 µg/L (0.73-69.27) with total of median 7.30 µg/L (2.38-132.19). The median Oxford, Harris, WOMAC, SF-36 and modified UCLA scores were 36 (6-48), 87 (21-100), 36 (24-110), 104 (10-125), and 3 (1-9), respectively. Seventeen patients had elevated serum cobalt and chromium levels ≥7 µg/L. There was no significant correlation between serum metal ion levels with any of these outcome scores. We recommend extreme caution during follow up of these patients with large head MoM arthroplasty.

The classification systems for tibial plateau fractures: how reliable are they?

OBJECTIVE: The aim of the study was to assess the inter-observer reliability and intraobserver reproducibility of three different classification systems for tibial plateau fractures. MATERIALS AND METHODS: Four observers of various levels of experience classified 50 tibial plateau fractures. The same observers repeated the classification of the same fractures after an interval of 8 weeks. Inter- and intra-observer variability was assessed using the mean kappa co-efficient and the mean percentage of agreement. RESULTS: For inter-observer reliability, the mean kappa co-efficient values for Arbeitsgemeinschaft für Osteosynthesefragen (AO), Schatzker and Hohl and Moore classifications were 0.36, 0.47 and 0.14, respectively. The mean percentage of agreement was 0.52, 0.59 and 0.34, respectively. For intra-observer reliability kappa-values were 0.80, 0.91 and 0.76 and the mean percentage of agreement was 0.88, 0.93 and 0.85 in the same order. CONCLUSIONS: Our results show that none of the classification systems were ideal. The Schatzker classification system was superior to the AO and the Hohl and Moore systems both in terms of inter-observer reliability and intra-observer reproducibility. However, there is a need for developing a more comprehensive approach to judge the classification systems.
