Background

Prospective study to compare patient reported outcome measures (PROM) for sacroiliac joint (SIJ) fusion using HA-coated screw (HACS) vs triangular titanium dowel (TTD). First study of its kind in English literature.

Introduction

Current undergraduate trauma and life-support training inadequately equips medical students with the knowledge, practical skills and confidence to manage trauma patients. Often first to the scene of medical emergencies, it is imperative junior doctors feel confident and competent from day one. No UK university currently includes advanced trauma and life support (ATLS) in their curriculum. This study piloted an ATLS course for Cardiff final-year medical students to improve confidence and knowledge in management of the trauma patient.

Abstract

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.

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.

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.

Bertolotti first described articulation of the L5 transverse process with the sacrum as a cause of back pain in 1917. Since then little attention has been payed to these atypical articulations despite their high reported incidence.

Here we describe our early experience of surgical treatment and propose a validated CT based classification of lumbosacral segment abnormalities (LSSA).

400 lumbosacral CT scans were reviewed (NBT), a classification devised and incidence of abnormalities recorded. 40 patients were selected and 4 independent observers classified each scan. Case notes for all patients (C&V) who received steroid injections into or surgical excision of LSSAs were reviewed. Results as follows:

5 types of abnormality were identified.

Type 0 - normal

Type 1 - asymmetrical shortening of the iliolumbar ligament

Type 2 - transverse process of L5 within 2mm of the sacrum

Type 3 - diarthrodial joint (3A: no evidence of degeneration 3B: degenerative change)

Type 4 - transverse process and sacrum have fused

Type 5 - extends to L4

54.5% of patients had abnormalities. The kappa values for the intra-observer results were 0.69 to 0.88 and the inter-observer ratings gave a combined score of over 0.7 indicating substantial agreement.

Our CT classification of LSSAs is both straight forward to use and repeatable. The incidence of these abnormalities is higher in our population of CT scans compared to previous published series using plain radiographs. All patients treated with surgical excision of established articulations (Type 3A or above) reported good or excellent outcomes following excision.

Objective

The aim of the study was to evaluate inter observer reliability and intra observer reproducibility between the three column classification using 3D CT reconstruction models and schatzker classification systems using 2D CT models.

Introduction

Previous studies have demonstrated the need of accurate reduction of ankle syndesmosis. Measurement of syndesmosis is difficult on plain radiographs. Recently, a difference of 2mm in anterior and posterior measurements at incisura of the inferior tibio-fibular joint on CT has been described as a measure of malreduction (depicted as ‘G’ for ease of description). Our practice changed towards routine post operative bilateral CT following syndesmosis fixation to assess the reduction and identify potential problems at an early stage. The aim of this primarily radiological study was to determine if the use of bilateral cross sectional imaging brings additional benefit above the more conventional practice of unilateral imaging.

Background and Objective

Patients undergoing hip fracture surgery have a high peri-operative mortality rate. We performed a retrospective study to ascertain if there is any relation between postoperative haemoglobin (Hb) decrease and cardiac related events following the surgery.

Fractures of the shaft of the humerus are often treated conservatively in a hanging cast or a humeral brace. The conservative management of this fracture is often prolonged and quite uncomfortable for the patient. Some of the patients will need an operative fixation after a trial of conservative management.

We retrospectively looked at 72 consecutive patients with fractures of the shaft of the humerus that presented in our institution over a period of two years. The fracture pattern, treatment modality time to union and the number that needed operative fixation following a trial of conservative treatment was analysed. Of the 72 patients 4 were lost to follow-up. 45 patients had a 1.2.B or 1.2.C type of fracture and 23 had a 1.2.A type of fracture. 29 (41%) were successfully treated conservatively, 11 (16%) patients were operated as the primary procedure and 15 (22%) patients were operated due to delayed or non union. 13 (19%) patients were operated within 4 weeks of the fracture as their alignment was not acceptable on their weekly follow-up.

The average time to union in the patients treated conservatively was 22 weeks, while that of the patients treated primarily by open reduction and plating was 14 weeks (p-value<0.05). Patients who needed operation after initial conservative management required prolonged period of rehabilitation and union time was 32.2 weeks. At the time of fracture union 72% of the patients who had been treated conservatively had joint stiffness requiring physiotherapy, while only 18% of those who had an open reduction and internal fixation had stiffness and required physiotherapy. (p-value < 0.05).

In conclusion careful consideration should be given before it is decided to treat this fracture conservatively especially in the case of 1.2.A fracture pattern.

Introduction

The elbow is the second most common site of non prosthetic joint dislocation. Simple elbow dislocation alone contributes to 11-28% of all elbow injuries. Post-reduction treatment methods include traditional plaster of Paris (POP) immobilisation followed by physiotherapy, sling application followed by early mobilisation and rapid motion. The aim of the study was to evaluate the final outcome and cost-effectiveness of the pop and the sling groups.

Introduction: Ankle fractures are the most common fracture presenting to any trauma unit in the country with an incidence of 100 per 100,000 in a population. The management and the outcome will very well depend on the mechanism of the injury but there is a window of opportunity of atleast 24hr before the swelling sets in making it technically difficult to operate and hence lengthening the hospital stay with a substantial financial cost. In times where the public health fundings are set to be rolled back and Department of Health been asked to contribute £2.3bn to the Treasury’s £5bn of public spending cuts in2010/1, health economics becomes a vital thread in consideration of treatment planning.

Aim: The study was aimed at determining the delay in definitive fixation of the ankle fractures from the time of presentation to the hospital and the reasons entailing the delay with a resultant economic negative resonance of it on the hospital budget spreadsheets and for the patient.

Method: A retrospective review of all ankle fracture patients operated during Sept 07 to Aug 08 in this hospital was performed. Electronic records were evaluated to identify the waiting times for the surgery and the reasons thereof. Calculations were performed based upon the days lost and calculated against the national minimum wage of £5.73 an hour for adults (workers aged 22 and over) and £4.77 an hour for workers aged 18 to 21 inclusive (often known as the developmental rate). Cost to the trust because of the extra stay was calculated as well.

Results: Total number of patients operated for ankle fracture during the study period was 159. The mean waiting time for surgery was 4.9 days (range 1 to 7.8 days). The mean duration of in-hospital stay for the procedure was 12 days. The commonest cause for the delay of surgery was soft tissue swelling (50%). The total number of patient days lost while waiting for selling to recede was 779.1. Based on the minimum wages considering 8 hours of a working day, the total economic loss to the GDP was approximately £35713.9. With the average cost of hospital stay per day being £ 365 patient the total expenditure to the trust for waiting for the ankle selling to recede was 1788 per patient.

Conclusion: Considering the current economic climate, which is set to affect the spending on the health care, its over time that economic consideration is given while considering the promptness of the action with NCEPOD also suggesting that operatic can be done at night if resources available. With European working time directive in play from august 2009 and open reduction and internal fixation considered a index operation it is possible to operate timely by a fresh surgical team.

Introduction: Unstable inter-trochanteric fractures are increasing in incidence and stable fixation can improve outcome by leading to earlier mobilisation and reduced mortality. The appropriate choice of implant is vital to ensure a satisfactory outcome.

Objectives: The objective of this study was to determine the load at which different intramedullary device constructs failed.

Materials and Methods: Nine identical 3rd generation composite Sawbones were used and prepared with reverse obliquity cuts made to the femoral necks. Three different types of trochanteric entry intramedullary nail were then inserted using manufacturer’s guidelines. The nine constructs were loaded to failure using a Dartec 9500 servo hydraulic testing machine.

Results: The average failure loads were 3954±952N for the DePuy nail, 2420±281N for the Synthes nail and 3810±377N for the Stryker nail. In eight of the nine constructs the Sawbone failed at the medial side of the fracture. One of the DePuy nails failed at 5041N in the area of the distal locking screws.

The Stryker nail constructs were significantly stronger than the Synthes constructs (p=0.008); although the DePuy constructs were similar in strength to the Stryker constructs (p=0.83) they were not significantly different from the Synthes constructs (p=0.098).

Conclusion: There must be a balance between movement at the fracture site to allow compression but enough stability that the fracture may heal.

Our study showed that the Synthes nail failed at a significantly lower load than the DePuy or the Stryker nails. The Synthes construct failed at a typical walking load, around three times body weight for an 80kg patient.

The knowledge of actual extent of the fracture in cases of isolated greater trochanteric fractures has paramount importance in decision-making. MRI has been the most common investigation to detect the intertrochanteric extension. However, to date there is no plain radiographic or MRI criteria to decide which fractures need surgery and which could be managed non-operatively. The aim of our study-was to assess whether the angle and the extent of the greater trochanteric fracture measured on plain radiographs could be used to predict the intertrochanteric extension.

We reviewed plain radiographs of 23 patients with isolated greater trochanteric fractures who also had MRI scans. We considered two parameters

extent of fracture in percentage along the intertrochanteric line and

Out of 23 patients, MRI scans revealed intertrochanteric extension in eight and they underwent surgical stabilisation. All these eight fractures had a fracture angle of 45° or less and the percentage of fracture extent of > 40%. All the 15 fractures with a fracture angle of > 45° did not show intertrochanteric extension on MRI scan. The mean angle of the fracture in those with MRI proven intertrochanteric extension was 33.5° (range 20°–45°) and in those with no intertrochanteric extension was 55.7° (Range 25°–125°). The mean percentage of length of fracture across the intertrochanteric line was 61.1% (47%–73%) and 39.6% (27%–62%) respectively.

We conclude that those isolated greater trochanteric fractures, with a fracture angle of more than 45° are unlikely to have an intertrochanteric extension. Those fractures with an extent of more than 40% and fracture angle less than 45° are likely to show inter trochanteric extension.

Sacroiliac joint (SIJ) is a diarthrodial joint and can often be a source of chronic low back pain complex. We present a percutaneous technique for SIJ fusion and the functional and radiological outcome following arthrodesis with HMA (Hollow modular anchorage; Aesculap Ltd, Tuttlingen) screws.

Fifteen consecutive patients operated for SIJ fusion between Sep 2004 and Aug 2007 were included in the study. The diagnosis was confirmed with MRI and diagnostic injections. Pre-operative and post-operative functional evaluation was performed using SF-36 questionnaire and Majeed’s scoring system. Postoperative radiological evaluation was performed using plain radiographs. The HMA screws packed with bone substitute were implanted percutaneous under fluoroscopic guidance.

The study group included 11 females and 4 males with a mean age of 48.7 years. Mean follow-up was 14 months. Mean SF-36 scores improved from 37 to 80 for physical function and from 53 to 86 for general health. The differences were statistically significant (Wilcoxon signed rank test; p < 0.05). Majeed’s score improved from mean 37 preoperative to mean 79 postoperative. The difference was statistically significant (student t test, p< 0.05). 13 had good to excellent results. The remaining 2 patients had improvement in SF-36 from mean 29 to 48. Persisting pain was potentially due to coexisting lumbar pathology. Intra-operative blood was minimal and there were no post-operative or radiological complications.

Percutaneous HMA screws are a satisfactory way to achieve sacroiliac stabilisation.

The treatment of femoral non-union, especially femoral exchanged nailing, has had mixed results in the recent literature. A review of the literature has suggested that exchanged nailing may be the gold standard for the treatment of femoral non-union. Is femoral exchange nailing an acceptable method of treatment of femoral fracture non-union? What is the evidence? In this systematic review we compare four different methods for the treatment of femoral non-union.

English speaking literature from 1970 to 2007 was searched using Pubmed^® and OVID™ databases and a manual reference search to reveal the original research, presenting the results of the treatment of femoral non-union with exchange nailing, plating, external fixation, and isolated bone grafting. Outcome parameters chosen were union rate and speed of union. The baseline variables chosen were age, number of surgeries, infection and the type of non-union.

In total, fifty six case series were identified containing 861 patients treated with exchange nailing (31 studies), 214 patients treated with plating (11 studies), 140 patients treated with external fixation (13 studies), 81 patients treated with bone grafting (4 studies). The average union rate was 89% for exchange nailing, 93% for plating and external fixation and 62% for bone grafting. Speed of union was 7.3 months for exchange nailing, 8.6 months for plating and 9.15 months for external fixation.

Study of baseline variables showed patients to be older in plating and external fixation groups (range 32–44 years, P< 0.001). There were more previous operations performed in the external fixation and plating groups (3 and 1.8 vs. 1.2, P< 0.001), significantly more infected non-unions in the plating and external fixation groups as compared to the exchange nailing group (40% vs. 11.5% P< 0.001) and significantly more atrophic non-unions in the plating and external fixation groups as compared to the exchange nailing group (85% vs. 65%, P< 0.001).

The literature suggests that femoral exchange nailing has an equivalent or poorer outcomes when compared to external fixation and plating in spite of having been performed in potentially less complex cases. Plating of non-union in the literature has a higher rate of associated bone grafting than femoral exchange nailing which may be responsible for marginally better union rate in the external fixation and plating groups.

Isolated bone grafting without revision of fixation does not provide adequate union rate and hence may be of questionable treatment value.

Proximal ulnar fractures may be difficult to treat and may result in chronic instability, non-union heterotrophic ossification, synostosis, stiffness and post-traumatic arthritis. The aim of this study is to study success of treatment in achieving stable reduction and early rehabilitation.

Between December 2003 and January 2007 fifty patients (fifty-one elbows) which had sustained 21.A3 and 21.C3 fractures were identified and retrospectively studied.

There were two broad groups of patients. Young males following high energy injuries (average age=38+/−16) and old females with osteoporotic fractures (average age=65+/−17). Twenty-two patients had associated monteggia and seven patients had trans-olacrenon dislocation. Twenty-three patients had radial sided injury. This included two capitelar fractures, nineteen radial head and neck fractures and one radial shaft fracture. Fortyfive patients were treated with plating and two patients were treated with tension band wiring. Five different plating techniques were used to stabilize the fractures.

Eighteen patients had incongruent reduction. Eighteen patients had complications of the treatment. There were seven cases of non-union, one case of loss of fixation, three cases of heterotrophic ossification, three cases of synostosis, one case of deep infection and five complications resulting from radial head fractures.

There was no relationship between loss of fixation and plating techniques. There was a direct relation between comminution and post fixation incongruence. Heterotrophic ossification was associated with comminution, radial head fracture, monteggia fracture-dislocation and non-union. Radio-ulnar synostosis was associated with comminution of the ulnar fracture.

In conclusion, the main predictor of poor outcome is the comminution of proximal ulnar fracture and the ability to achieve congruous fracture fixation.

Introduction: Isolated greater trochanter fractures gained clinical importance because of the possibility of their inter-trochanteric extension.

Aim: To assess whether the direction and the extent of the fracture measured on plain radiographs could be used to predict the inter-trochanteric extension.

Materials and Methods: We reviewed plain radiographs and MRI scans of 24 patients who sustained isolated greater trochanter fractures between year 2003 and 2006. We considered two parameters

extent of fracture in percentage along the intertrochanteric line

Both these parameters were measured on a plain anteroposterior radiograph. To measure the length of fracture we have drawn a straight line along the medial border of femoral shaft extending proximally in to the pelvis. Then we measured the distance between the most superior point of the fracture line on the lateral cortex and the midpoint of lesser trochanter on the first line. Then we measured the length of the fracture starting from the most superior point on the lateral cortex. We estimated the percentage of this fracture length in relation to line.

To estimate the angle, again we have drawn a straight line along the medial border of femoral shaft extending proximally in to the pelvis. We have drawn another line in the direction of fracture staring from most superior point of fracture on the lateral cortex joining the first line. We measured the angle between these two lines (Fig 2). We used our Hospital PACS system to measure the angles and the length of the fracture.

Results: Out of 24 isolated greater trochanteric fractures as diagnosed by plain radiographs, MRI scans revealed intertrochanteric extension in nine (37.5%). On the plain anteroposterior radiograph, the mean angle of the fracture in those with MRI proven intertrochanteric extension was 34º (range 20º–45º). In those with no intertrochanteric extension on MRI scan, the mean angle was 55º (Range 25º–125º). The mean percentage of length of fracture across the intertrochanteric line was 62% (47%–73%) and 40% (27%–62%) respectively. All the fractures with MRI proven intertrochanteric extension had a fracture angle of < 45º and the percentage of fracture length of > 40%. All the 15 fractures with fracture angle more than 45º did not show intertrochanteric extension on MRI scan

Conclusions: We conclude that those isolated greater trochanteric fractures, with fracture angle of more than 45 º are unlikely to have an intertrochanteric extension. These patients could be mobilised without further MRI scans. Those fractures which fulfil the plain radiographic criteria of extension of more than 40% and fracture angle between 20º–40º are likely to show inter trochanteric extension. These patients need further clinical assessment and MRI scans to confirm the intertrochanteric extension.

Introduction: Sacroiliac joint (SIJ) is a diarthrodial joint and can often be a source of chronic low back pain complex. We present a percutaneous technique for SIJ fusion and the functional and radiological outcome following the arthrodesis.

Aims and Objectives: To evaluate the functional and radiological outcome following percutaneous technique for SIJ fusion with HMA (Hollow modular anchor-age) screws.

Materials and Methods: 15 consecutive patients operated for SIJ fusion between Sep 2004 and Aug 2007 were included in the study. The diagnosis was confirmed with MRI and diagnostic injections. Pre-operative and post-operative functional evaluation was performed using SF-36 questionnaire and Majeed’s scoring system. Postoperative radiological evaluation was performed using plain radiographs. The Hollow modular anchorage (HMA) screws (Aesculap Ltd, Tuttlingen) packed with bone substitute were implanted percutaneous under fluoroscopic guidance

Results: The study group included 11 females and 4 males with a mean age of 48.7 years. Mean follow-up was 14 months. Mean SF-36 scores improved from 37 to 80 for physical function and from 53 to 86 for general health. The differences were statistically significant (Wilcoxon signed rank test; p < 0.05). Majeed’s score improved from mean 37 preoperative to mean 79 postoperative. The difference was statistically significant (student t test, p< 0.05). 13 had good to excellent results. The remaining 2 patients had improvement in SF-36 from mean 29 to 48. Persisting pain was potentially due to coexisting lumbar pathology. Intra-operative blood was minimal and there were no post operative or radiological complications in any patient.

Conclusion: Percutaneous HMA screws are a satisfactory way to achieve sacro-iliac stabilisation.
