Hindfoot intramedullary nail fixation (HFN) or fibula pro-tibial screw fixation (PTS) are surgical options for ankle fractures in patients with multiple co-morbidities; we compared their outcomes. A retrospective review of 135 patients who underwent HFN fixation (87 patients) or PTS fixation (48 patients) for ankle fractures (AO/OTA A/B/C) from 5 major trauma centres. Patient demographic data, co-morbidities, Charlson Co-morbidity Index Score (CCIS), weight-bearing, and post-operative complications were recorded. Radiographs were assessed for non-union and anatomical reduction.Introduction

Anatomic reduction of talar body fractures is critical in restoring congruency to the talocrural joint. Previous studies have indicated a maximum of 25% talar body exposure without malleolar osteotomy. The aim of this study was to investigate the percentage talar body exposure when using the lateral transligamentous approach. The lateral transligamentous approach to the talus was undertaken in 10 fresh frozen cadaveric specimens by surgeons inexperienced in the approach, following demonstration of the technique. An incision was made on the anterolateral aspect of the ankle augmented by the removal of the anterior talofibular ligament (ATFL) and the calcaneofibular ligament (CFL) from their fibular insertions. A bone lever was then placed behind the lateral aspect of the talus and levered forward with the foot in equinus and inversion. The talus was disarticulated and high resolution images were taken of the talar dome surface. The images were overlain with a reproducible nine-grid division. Accessibility to each zone within the grid with a perpendicular surgical blade was documented. ImageJ software was used to calculate the surface area exposed with each approach.Introduction

The current treatment for Freiberg's osteochondrosis centres around either: simple debridement or debridement osteotomy. The main principle of the osteotomy is to rotate normal articular cartilage into the affected area. We recommend the use of CT scanning to delineate the amount of available, unaffected cartilage available to rotate into the affected space. We retrospectively reviewed 32 CT scans of new Freiberg's diagnoses in Sheffield over a 10 year period using the PACS system. We identified the sagittal CT slice that displayed the widest portion of proximal articular margin of the proximal phalanx and measured the diseased segment of the corresponding metatarsal head as an arc (in degrees). This arc segment was divided by 360°. This gave a ratio of the affected arc in the sagittal plane.Introduction

Ankle fractures in the elderly are an increasing problem with our aging population. Options for treatment include non-operative and operative with a range of techniques available. Failure of treatment can lead to significant complications, morbidity and poor function. We compared the outcomes of two operative techniques, intramedullary hindfoot nailing (IMN) and fibular-pro-tibia fixation (FPT). This is the largest analysis of these techniques and there are no comparative studies published. We retrospectively reviewed patients over the age of 60 with ankle fractures who were treated operatively between 2012 and 2017. We identified 1417 cases, including 27 patients treated with IMN and 41 treated with FPT. Age, sex, co-morbidities and injury pattern were collected. Primary outcome was re-operation rate. Secondary outcomes included other complications, length of stay and functional status.Introduction
Method
Total femoral arthroplasty (TFA) is a rare procedure used in cases of significant femoral bone loss, commonly from cancer, infection, and trauma. Low patient numbers have resulted in limited published work on long-term outcomes, and even less regarding TFA undertaken for non-oncological indications. The aim of this study was to evaluate the long-term clinical outcomes of all TFAs in our unit. Data were collected retrospectively from a large tertiary referral revision arthroplasty unit’s database. Inclusion criteria included all patients who underwent TFA in our unit. Preoperative demographics, operative factors, and short- and long-term outcomes were collected for analysis. Outcome was defined using the Musculoskeletal Infection Society (MSIS) outcome reporting tool.Aims
Methods
The primary aim of this study was to compare the clinical outcomes of osteoid osteoma (OO) between the group of patients with the presence of nidus on biopsy samples from radiofrequency ablation (RFA) with those without nidus. Secondly, we aimed to examine other factors that may affect the outcomes of OO reflecting our experience as a tertiary orthopaedic oncology centre. We retrospectively reviewed 88 consecutive patients diagnosed with OO treated with RFA between November 2005 and March 2015, consisting of 63 males (72%) and 25 females (28%). Sixty-six patients (75%) had nidus present in their biopsy samples. Patients’ mean age was 17.6 years (4-53). Median duration of follow-up was 12.5 months (6-20.8). Lesions were located in the appendicular skeleton in seventy-nine patients (90%) while nine patients (10%) had an OO in the axial skeleton. Outcomes assessed were based on patients’ pain alleviation (partial, complete, or no pain improvement) and the need for further interventions. Pain improvement in the patient group with nidus in histology sample was significantly better than the group without nidus (OR 7.4, CI 1.35-41.4, p=0.021). The patient group with nidus on biopsy demonstrated less likelihood of having a repeat procedure compared to the group without nidus (OR 0.092, CI 0.016-0.542, p=0.008). Our study showed significantly better outcomes in pain improvement in appendicular lesions compared to the axially located lesions (p = 0.005). Patients with spinal lesions tend to have relatively poor pain relief than those with appendicular or pelvic lesions (p=0.007). Patients with nidus on histology had better pain alleviation compared to patients without nidus. The histological presence of nidus significantly reduces the chance of repeat interventions. The pain alleviation of OO following RFA is better in patients with appendicular lesions than spinal or axially located lesions.
There is little literature exploring clinical outcomes of secondarily displaced proximal humerus fractures. The aim of this study was to assess the rate of secondary displacement in undisplaced proximal humeral fractures (PHF) and their clinical outcomes. This was a retrospective cohort study of undisplaced PHFs at Royal Derby Hospital, UK, between January 2018-December 2019. Radiographs were reviewed for displacement and classified according to Neer's classification. Displacement was defined as translation of fracture fragments by greater than 1cm or 20° of angulation. Patients with pathological, periprosthetic, bilateral, fracture dislocations and head-split fractures were excluded along with those without adequate radiological follow-up.Abstract

Prosthetic joint infection (PJI) is the leading cause of failure of primary and revision hip and knee arthroplasty. It is challenging condition which represents a growing burden on hospital resources. In-patient hospital stay for antibiotic therapy post-operatively is costly and access to out-patient IV therapy (OPAT) varies between regions. In a tertiary referral centre for revision and infection, the suitability and cost-effectiveness of Dalbavancin was reviewed as a “single-shot” therapy following DAIR or revision lower limb arthroplasty for PJI. A prospective service evaluation was carried out for consecutive patients treated for PJI of the hip or knee who received Dalbavancin. Treatment was indicated by Consultant Microbiologist advice within an MDT setting where clinical or patient factors made alternative therapies eg. OPAT inappropriate. Service-level data was collected to allow calculation of bed-day savings compared to a traditional 14-day course of IV treatment. Readmission rates to the trust within 30 days were reviewed as a marker of clinical efficacy and safety.Introduction
Methods & Materials
Standard teaching of dislocated ankles was always reduce then x-ray. However the 2016 BOAST guidelines stated “Reduction and splinting should be performed urgently for clinically deformed ankles. Radiographs should be obtained before reduction unless this will cause an unacceptable delay”. We aimed to audit our practice against the BOAST guidelines and look at time from attendance to reduction. We retrospectively reviewed all case notes of patients admitted via A&E at the Northern General Hospital with a fractured ankle between August 2016 and January 2017. Time of arrival, time to x-ray and time to reduction were recorded in a database for analysis.Introduction
Methods
Avulsion fractures of the base of the fifth metatarsal are some of the commonest foot injuries. The robust scientific evidence on the optimal non-operative treatment of these fractures is scant. We designed and conducted a prospective randomised non-inferiority controlled trial of symptomatic treatment versus cast immobilisation with the null hypothesis that cast immobilisation gave substantial benefit over the symptomatic treatment in terms of patient reported outcome measures(PROMs). The alternative hypothesis was that symptomatic treatment was not inferior. The primary outcome was the validated Visual Analogue Scale Foot and Ankle (VAS FA) score ranging from 0 to 100. The non-inferiority boundary was set at −10 points. Power sizing determined a minimum of 12 patients per group. Anticipating a significant loss to follow up, 60 patients of 16 years of age or older were randomised to receive either below knee walking cast immobilisation (n = 24) or symptomatic double- elasticated bandage (n = 36) for 4 weeks. Secondary outcome measures were EuroQol-5D, and American Orthopaedic Foot and Ankle Society scores. Data was analysed at the baseline, 4 weeks, 3 months and 6 months post injury by a clinician blinded to a treatment arm.Background

Patients suffering a distal femoral fracture are at a high risk of morbidity and mortality. Currently this cohort is not afforded the same resources as those with hip fractures. This study aims to compare their mortality rates and assess whether surgical intervention improves either outcome or mortality following distal femoral fractures. Patients over sixty-five admitted with a distal femoral fracture between June 2007 and 2012 were retrospectively identified. Patients mobility was categorised as unaided, walking aid, zimmer frame, or immobile. The 30-day, six-month, and one-year mortality rates were recorded for this group as well as for hip fractures during the same period.Background

Although infrequent, a fracture of the cuboid can lead to significant
disruption of the integrity of the midfoot and its function. The
purpose of this study was to classify the pattern of fractures of
the cuboid, relate them to the mechanism of injury and suggest methods
of managing them. We performed a retrospective review of patients with radiologically
reported cuboid fractures. Fractures were grouped according to commonly
occurring patterns of injury. A total of 192 fractures in 188 patients
were included. They were classified into five patterns of injury.Aims
Patients and Methods
Most of current literatures advise on thromboprophylaxis with injectable LMWH for trauma patients. Injectable anticoagulants have got inherent problems of pain, bruising and difficulty in administering the drug, which leads to low compliance. Clexane is derived from a pig's intestinal mucosa, hence could be objectionable to certain proportion of patients because of their religious beliefs. Oral anticoagulants have been used as thromboprophylactic agents in hip and knee arthroplasty. However there is not enough literature supporting their use as thromboprophylactic agent in ambulatory trauma patients with ankle fracture being managed non-operatively as out-patient. This study looks into the efficacy of oral anticoagulant in preventing VTE in ambulatory trauma patients requiring temporary lower limb immobilisation for management of ankle fracture. The end point of this study was symptomatic deep vein thrombosis (either proximal or distal) and pulmonary embolism. Routine assessment with a VTE assessment risk proforma for all patients with temporary lower limb immobilisation following lower limb injury requiring plaster cast is done in the fracture clinic at this university hospital. These patients are categorised as low or high risk for a venous thromboembolic event depending on their risk factor and accordingly started on prophylactic dose of oral anticoagulant (Rivaroxaban - Factor Xa inhibitor). Before the therapy is started these patients have a routing blood check, which includes a full blood count and urea and electrolyte. Therapy is continued for the duration of immobilisation. Bleeding risk assessment is done using a proforma based on NICE guideline CG92. If there is any concern specialist haematologist advice is sought. A total of 200 consecutive patients who presented to the fracture clinic with ankle fracture, which was managed in plaster cast non-operatively, were included in this study. They were followed up for three months following injury. This was done by checking these patients’ radiology report including ultrasound and CT pulmonary scan (CTPA) test on hospital's electronic system. Fracture of the lateral malleolus which include Weber-A, Weber-B and Weber-C fractures were included in the study. Also included were bimalleolar fractures and isolated medial malleolus fractures. Complex pilon fractures, polytrauma and paediatric patients were excluded from the study. Only one case of plaster associated isolated distal deep vein (soleal vein) thrombosis was reported in this patient subgroup. There was no incidence of proximal deep vein thrombosis or pulmonary embolism. No significant bleeding event was reported. Injectable low molecular weight heparin (LMWH) rather than oral anticoagulant has been recommended by most of the studies and guidelines as main thromboprophylactic agent for lower limb trauma patients.
The surgical treatment of intractable metatarsalgia has been traditionally been an intra-articular Weil's type of metatarsal osteotomy. In such cases, we adopted the option of performing a minimally invasive distal metaphyseal metatarsal ostetomy (DMMO) to decompress the affected ray. The meta-tarsophalangeal joint was not jeopardised. We present our outcomes of Minimally Invasive Surgery for metatarsalgia performed at our teaching hospital. This is a multi-surgeon consecutive series of all the thirty patients who underwent DMMO. The sex ratio was M: F- 13:17. Average age of patients was 60 yrs. More than one metatarsal osteotomy was done in all cases. The aim was to try and decompress the affected rays but at the same time, restore the metatarsal parabola. It was performed under image-intensifier guidance, using burrs inserted via stab incisions. Patients were encouraged to walk on operated foot straight after the operation; the rationale being that the metatarsal length sets automatically upon weight bearing on the foot. Outcome was measured with Manchester-Oxford Foot Questionnaire's (MOXFQ's) and visual analogue pain score (VAS). Minimum follow up was for six months.Introduction:

Prompted by the success of hip and knee arthroplasty, total ankle replacement (TAR) has become increasingly popular as a treatment for end stage arthritic complaints of the ankle. Glazebrook et al proposed a three grade classification of complications to assist prediction of early implant failure. We have compared the experience of a tertiary referral centre in the UK to Glazebrook's proposed system. A retrospective review of the Sheffield Foot and Ankle Unit TAR database was performed from 1995 to 2010. All complications were recorded and categorised using Glazebrook's proposed system. Glazebrook described eight main complications of increasing severity. Low grade complications; Post operative bone fracture, Intra-operative bone fracture and wound healing problems were very unlikely to lead to revision. Medium grade complications; technical error and subsidence, lead to failure < 50% of the time. High grade complications; deep infection, aseptic loosening and implant failure lead to revision > 50% of the time.Introduction:
Method:
Locked plates confer angular stability across fusion sites, and as such are more rigid than either screws or intramedullary nails. This gives the advantage of reducing motion to enhance union rates and potentially allowing early weight bearing. The Philos plate (Synthes) is a contoured locking plate designed to fix humeral fractures but which also fits the shape of the hindfoot and provides strong low profile fixation. Its successful use for Our aim was to prospectively evaluate the use of the Philos plate in hindfoot arthrodesis Twenty-one hindfoot arthrodeses were performed using the Philos plate between Oct 2008 and Jan 2010. Patients were followed up for a minimum of 1 year and had preoperative and 6 monthly AOFAS hindfoot scores and serial radiographs until union. Overall there were 15 ankle fusions, 5 Our conclusion is that the high non-union rates are probably due to the lack of compression conferred across the join by the Philos plate as there is no compression hole and we did not supplement the fixation with a lag screw. We recommend using locked plates for hindfoot arthrodesis only with additional compression.
Growing evidence in the literature suggests better clinical and functional outcomes and lower re-rupture rates with repair compared to non-operative treatment of ruptured Achilles tendon. There are however, concerns of wound infection, nerve injury and scar tenderness with the standard open and percutaneous techniques of repair. We aim to evaluate clinical and functional outcomes and complications in patients treated with minimally invasive Achillon device. Prospectively collected clinical data was reviewed of all consecutive patients who underwent repair of the ruptured Achilles tendon using the Achillon device. Patients were contacted using a postal questionnaire for assessment of their functional status using the validated Achilles Tendon Total Rupture Score (ATRS) and compared with their uninjured side. The outcomes were compared to the published results.Introduction

There is mixed evidence in the literature regarding increasing age, ASA and BMI as risk factors for surgical site infection in orthopaedic surgery. To investigate the matter further, we examined 1055 wounds in 1008 patients in the Department of Trauma and Orthopaedic Surgery at University College London Hospital between 2000 and 2006. All patients with a minimum two-night stay were included. Data was collected by four designated research nurses. The age, height, weight and ASA status of each patient was recorded. All wounds were classified using ASEPSIS. This is a quantitative wound scoring method which is a summation of scores calculated from visual wound characteristics and the clinical consequences of infection. Our results showed a strong linear association between age and ASEPSIS scores. Single variable regression analysis showed a t value of 3.32 and p value of 0.001. A similar linear association was seen between ASA grading and ASEPSIS scores. Single variable regression analysis showed a t value of 2.75 and p value of 0.006. The association between BMI and ASEPSIS scores was markedly different from that seen with age and ASA. The graph was U-shaped with patients with a BMI of 25-30 having the lowest average ASEPSIS scores. Patients with a lower and a higher BMI had higher average ASEPSIS scores. Single variable regression analysis was not significant since the relationship between BMI and ASEPSIS scores is not linear. In conclusion, there are clearly defined patient groups who are at increased risk of developing a surgical site infection: older patients, patients with a higher ASA, and patients with both a low and high BMI. These patients should be targeted to reduce overall infection rates. This can be achieved by ensuring adequate antibiotic prophylaxis, having a low threshold to treat suspected infection and arranging regular follow-up.
Injection studies had an impact on subsequent management in 88% of cases. Symptoms resolved with injection alone in 28% of patients with no communication versus 8% in those with a communication. Surgical plans were changed in over 20% of cases if a joint communication was found. There were no major complications reported (Joint sepsis or contrast allergy).
We would recommend joint injection be considered in all patients, especially if joint fusion is being considered. Contrast should be used in all cases to demonstrate any potential communications, which should be taken into consideration when surgical management plans are formulated. A significant number of patients will experience resolution of symptoms from injection alone, with no further intervention needed.
We propose that ASEPSIS provides the most accurate and reproducible results and also provides more information with the grading of wound infection. The overall rate of orthopaedic wound infection using the ASEPSIS method is 3%. If all hospitals used this scoring method, more accurate comparisons of infection rates could be made.
A centralized wait list management system (WLMS) for TKR, THR and knee arthroscopy was developed to collect accurate data on parameters of patients’ wait for surgery. A priority metric rating patient priority was implemented. Data from hospital enterprise systems related to aspects of patients’ wait for surgery was collected and imported. Patients’ functional status was significantly worse than population norms, they were adversely affected while waiting and are unsatisfied with their access to surgery. Traffic ratios (ratio of booked to completed surgeries) exceed the maximum value for a stable wait list and the waits for surgery exceed national and international recommendations for maximum wait-times. To develop and implement a WLMS for TKR, THR and knee arthroscopy to enable the accurate and efficient collection of data on size of list, rate of list growth, rate surgeries are performed, health and functional status of patients, and surgeon rated priority. Patients are adversely affected while waiting and are unsatisfied with the length of their wait. Traffic ratios exceed the maximum value for a stable waitlist. The priority metric has face validity for rating patient acuity. SF36 and WOMAC scores were three to four standard deviations worse than the population norm, over 50% of patients felt wait time would negatively affect outcome, 80% felt waits should be twelve months or less, and over 50% were unsatisfied with access to surgery. VAS scores were normally distributed with good face validity. Wait times are one hundred and thirty to three hundred days for arthroplasty and ninety to four hundred days for arthroscopy. Traffic ratios are 0.9 for arthroplasty and 1.5 for arthroscopy. Prospective outcomes with respect to the wait list will allow determination of minimum acceptable wait times from administrative, surgeon and patient perspectives. Accurate and reliable collection of wait list data provides a sound basis for future decision-making. Surgery bookings were centralized. A priority metric based on a visual analog scale (VAS) with a single question asking the surgeon to rate the patient priority was implemented. A cross-sectional postal survey was conducted. Data from hospital enterprise systems related to aspects of patients’ wait for surgery was collected and imported into the WLMS.

Ankle fractures are common injuries and commonly require operative stabilisation. The aim of treatment should be anatomical reduction as this will lead to good long-term results. Non-anatomically reduced fractures will lead to a poor functional outcome and development of osteoarthritis. Our aim was to determine whether revision of non-anatomical fixations within 12 months of initial surgery improved outcome. We present eight cases of non-anatomical ankle fixations that were revised by the senior author over a 4-year period. There were 4 females and 4 males. The mean age was 45.6 years at review (range 28–63) and the mean time from initial fixation to revision was 5.25 months (range 2–11). Mean time at review was 26.6 months (range 7–45). Clinical scoring for functional outcome was performed using the American Orthopaedic Foot and Ankle Society (AOFAS) rating system for the ankle and hindfoot. Mean AOFAS score prior to revision was 40 (range 19–69) and the mean score at review was 80 (range 54–100). All patients reported benefit in terms of function from the revision procedure. The aim of initial surgery is for anatomical reduction of the ankle joint. Should suboptimal fixation be encountered within 12 months of the initial surgery, we feel revision surgery is justified.
Despite the literature reporting a high complication rate tension band wiring remains a common technique for the fixation of olecranon fractures. In our unit 44 patients who underwent tension band wiring of olecranon fractures between May 1998 and May 2002 were reviewed specifically with regards factors that might be responsible for a poor outcome. The patient’s age at the time of injury, mode of injury and fracture configuration were recorded. In addition the adequacy of reduction was assessed and the position of the k-wires (parallel/non-parrallel, anterior cortex fixing/intramedullary) length of wire beyond the fracture line and number of circlage wire twists noted. All patients had a minimum follow-up of 12 months. 22 patients (50%) had complications following the index procedure of which 8 had wire back out, 7 had pain and discomfort requiring removal of the metalwork and 4 had wound infections. Fixation of the radius occurred in 1 patient and 2 patients developed a non-union. In all further surgery was needed in 18 patients (41%). No common features were identified in patients developing complications and in particular no statistical difference was found when k-wire position (P=0.35) length of k-wire beyond the fracture line (P=0.34) and number of circlage wire twists (P=0.33) were analysed. Using Kaplan-Meier analysis the patients who required wire removal were likely to undergo their surgery within 6 months of fracture fixation. The high complication rate begs the question: Is this an appropriate modern method of fracture fixation?
The purpose of this study was to design a clinically useful classification for distal humeral fractures that would provide guidance to the surgeon with regard to surgical approach and operative management. This classification was assessed using the original radiographs from a study comparing distal humeral fracture classifications previously undertaken in Oxford, and validated using the exact methodology of that study. Nine independent assessors (3 orthopaedic consultants, 3 orthopaedic registrars and 3 musculoskeletal radiologists) were asked to classify 33 sets of radiographs on two separate occasions using the Riseborough and Radin, Jupiter and Mehne, and AO classifications as well as the new classification system. The assessors were unaware of the origin of the new system as this had been given a fictitious name. Using the Kappa statistic, the level of inter-observer and intra-observer agreement was determined and interpreted using the Landis and Koch criteria. Amongst all observers, the new classification is both a substantially reliable (k=0.664) and reproducible (k=0.732) classification system. The new classification achieved superior inter- and intra-observer agreement compared to the other three classification systems with a low proportion of unclassifiable fractures comparable to the AO method (3.7%). In reproducing materials and methodology from an independent study, we have been able to validate this new fracture classification system. Used in conjunction with a management algorithm, we believe the new classification aids the surgical decision-making process for these complex fractures.
An inability to extend the hallux following trauma is most often observed after direct laceration to the Extensor Hallucis Longus [EHL]. Primary repair, subsequent splinting and appropriate rehabilitation best deal with this type of injury. Damage to either the EHL muscle belly or the motor nerve to EHL are uncommon causes of the dropped hallux and present difficult reconstructive problems. Damage to the motor nerve branch to EHL in isolation is an uncommon problem and as far as we are aware surgery to address this pathology has not previously been described in the literature. This problem can occur after a penetrating injury, high tibial osteotomy or intramedullary nailing of a fractured tibia. We describe the operative procedure, technique and outcome in two cases of extensor hallucis longus to extensor digitorum communis (EDC) transfer to overcome this problem. A longitudinal skin incision is made just lateral to the tibia in the distal anterior part of the leg. The extensor retinaculum is divided and the EHL tendon identified and divided just distal to the EHL musculotendinous junction. The extensor digitorum communis (EDC) is then identified and the proximal stump of EHL woven into the EDC. A Pulvertaft weave technique is used and secured with 3/0 Ethibond suture. The appropriate amount of tension is placed on the repair by simulating weight bearing on the foot, ensuring the great toe remains in the neutral position. The extensor retinaculum is then repaired with 2/0 Vicryl and the skin closed with interrupted nylon sutures. The wound is infiltrated with 0.5% Marcaine to aid postoperative pain relief. A protected active motion rehabilitation program follows the surgery. We have used this technique in two cases, both have regained active extension of the hallux.
The Scarf osteotomy has proven to be an effective intervention in the correction of various degrees of hallux valgus deformity. Outcome compares favourably with other bunion surgeries such as the distal or proximal Chevron or crescentic osteotomy. The Scarf osteotomy is a more extensive surgical procedure than other techniques and the technically demanding nature of the procedure requires experience to master. This paper describes peri-operative complications during our early experience of Scarf osteotomy for hallux valgus. A case note review was carried out for the first 100 Scarf osteotomy procedures completed by the senior author. There were six patients (6%) with peri-operative complications. Four of these were intra-operative complications including a split of the first metatarsal in three cases, and a shearing of the K wire in one case, and there were two cases of post-operative stress fracture. These complications should be considered by those beginning to master the Scarf osteotomy procedure and by surgeons teaching surgical trainees.
This study was designed to assess the standard of orthopaedic training of Senior House Officers in the U.K. and to determine the optimum time that should be spent in these posts before registrar training. Two MCQ papers were constructed. One for the pre test and one for the post test. Questions covered all aspects of orthopaedics and trauma including operative surgery. The paper was firstly tested on controls including medical students, house officers, registrars of various grades and consultants. There was no statistical difference in the results for the two papers within the groups indicating that pre and post test papers were of similar standard. In addition the average scores in the tests increased proportionately to the experience and grade of the control. 129 SHOs from 25 hospitals in 10 different regions were tested by MCQ examination at the beginning of their 6-month post. They were again tested at the end of the job. The differences in score were compared. This difference was then correlated with the experience and career intention of the SHO. There was no statistical difference between pre and post test results in all groups of SHOs in the study (student t test). The best improvement in scores during this six month period were seen in SHOs of 1–1.5 years orthopaedic experience. SHOs of more than 3 years experience demonstrated the smallest improvement in their score. There was a net loss of seven trainees with a career intention of orthopaedics to other disciplines. In the vast majority of Senior House Officer posts in this country, very little seems to be learnt during a six-month attachment. This is especially so for those who are doing orthopaedics for the first time as well as very experienced SHOs.
Meticulous haemostasis not only improves the operative field facilitating spinal surgery, but also diminishes chances of post-operative neurological complications from a compressive haematoma. Since being introduced in the 1940’s, implantable haemostats have proven a useful adjunct in achieving haemostasis with relatively few complications. However, their use in spaces bounded by bony architecture can lead to compressive effects on neurological structures. We present three cases of post-operative cauda equina syndrome – two cases following surgery for lumbar disc herniation and one case following surgery for lumbar canal stenosis. In each case, implantable haemostats were utilised to control haemorrhage for complications during the surgery. All three patients underwent urgent exploration, which revealed cauda equina compression from clot organised around the haemostat. Neurological recovery was variable. We recommend careful attention to intra-operative haemostasis. Although haemostats can assist in achieving haemostasis, we caution against leaving them in situ.
The reproduction of symptoms on arthrography of the lumbar facet joint has been accepted as a screening procedure before localised spinal fusion. We studied the histology of 127 facet joints removed at operation from 84 patients, who had previously had facet arthrography. The specificity of the arthrographic results for degenerative joint disease was 75% but their sensitivity was only 59%. This gave a positive predictive value of 85%, but a negative predictive value of only 43%. We conclude that the production of symptoms during facet arthrography is of little value as a screening procedure.
