29 cases of complex elbow injuries were reviewed at a mean period of 15 months. Outcome measures included MEPS and DASH score. Patients who had defined early surgery were significantly better than those in whom surgery was delayed. We concluded that Management of complex elbow injuries can be improved by early definitive surgery. The magnitude and type of soft tissue injuries should be identified. MRI scans should be liberally used for this purpose. We believe that early, adequate and appropriate management of soft tissue injuries including use of articulated external fixator for early mobilisation improves the outcome of complex elbow injuries.

Aims

The BOA/BAPRAS guidelines for the management of open tibial fractures (2009) recommend early senior combined orthoplastics input and appropriate facilities to manage a high caseload. St Georges Hospital is one of four London Trauma Centres fulfilling these criteria. Our aim is to determine whether becoming a trauma centre has affected the management of patients with open tibial fractures.

Methods

Data were obtained prospectively on consecutive open tibial fractures during two 8 month periods: before and after becoming a Major Trauma Centre (May 2009–Dec 2009 and April 2010–Oct 2010 respectively). Data on patient pathway including, admitting hospital, length of stay, timing and number of operations were recorded.

Bizarre parosteal osteochondromatous proliferation (BPOP), or Nora's lesion, is a rare condition characterised by the formation of surface-based osteocartilaginous lesions typically affecting the hands and feet. 22 cases were identified from the records of a regional bone tumour unit, dating from 1985 to 2009. Of 22 cases, 9 lesions involved the long bones of the hand, 7 the long bones of the feet, 1 case originated from a sesamoid bone of the foot and 5 from long bones (radius, ulna, femur [2] and tibia). Age ranged from 6 to 66 (mean: 31.8) and male to female ratio was 1.8:1. Diagnosis was based on combined radiological and histological features, and initial surgical treatment was excision in 21 cases, and 1 amputation. Follow-up ranged from 12–162 months (mean 32). Recurrence occurred in 6 patients (27%), with mean time to recurrence 49 months (range 10–120). 2 of 8 patients with complete resection margins developed recurrence (25%), versus 4 of 14 with marginal or incomplete resection (28%). Given the potential surgical morbidity inherent in resection, our data suggest that there may be a role for a relatively tissue-conserving approach to the excision of these lesions.

Introduction

Haemodynamically compromised patients with biomechanically unstable pelvic fractures need reduction of the pelvic volume to effect tamponade of bleeding bone and vessels. Knee binding, to help achieve this, is advocated in standard Advanced Trauma and Life Support teaching but is rarely used. There are no reports in the literature as to the benefits derived from this simple manoeuvre. The aim of this study was to investigate whether there was an effect on symphysis pubis closure by binding the knees together and to quantify this.

Methods

13 consecutive patients who underwent open reduction and internal fixation of pubic symphysis diastasis +/− sacroiliac joint fixation were recruited prospectively. These patients were transferred from peripheral hospitals to this National tertiary referral level 1 trauma centre for definitive pelvic fracture management. All patients had sustained Antero-Posterior Compression (APC) type pelvic injuries. In theatre, a centred antero-posterior (AP) radiograph was taken without any form of binding on the pelvis. A second AP radiograph was then taken with the knees and ankles held together with the hips internally rotated. A third, final AP radiograph was taken post fixation. Measurements of symphysis pubis widening were made of the digital images taken in theatre.

Introduction

The proximity of the superior tibiofibular articulation to neurovascular structures makes the management of extraosseous tumours of the proximal fibula challenging in bone tumour surgery. The aim of study is to establish whether the recurrence rates are higher in this anatomical area compared to data that already exists in publication for bone tumours throughout the appendicular skeleton.

Method

A retrospective study of all patients treated for Ewing's tumours and osteosarcoma at a regional bone tumour unit between January 1995 and December 2009 was conducted.

We describe 22 cases of bizarre parosteal osteochondromatous proliferation, or Nora’s lesion. These are surface-based osteocartilaginous lesions typically affecting the hands and feet. All patients were identified from the records of a regional bone tumour unit and were treated between 1985 and 2009. Nine lesions involved the metacarpals, seven the metatarsals, one originated from a sesamoid bone of the foot and five from long bones (radius, ulna, tibia, and femur in two). The mean age of the patients was 31.8 years (6 to 66), with 14 men and eight women. Diagnosis was based on the radiological and histological features. The initial surgical treatment was excision in 21 cases and amputation of a toe in one. The mean follow-up was for 32 months (12 to 162). Recurrence occurred in six patients (27.3%), with a mean time to recurrence of 49 months (10 to 120). Two of the eight patients with complete resection margins developed a recurrence (25.0%), compared with four of 14 with a marginal or incomplete resection (28.6%).

Given the potential surgical morbidity inherent in resection, our data suggest that there may be a role for a relatively tissue-conserving approach to the excision of these lesions.

Navigation in total knee replacement is now used more frequently. The proven benefits in comparison to a conventional knee replacement include reduced hospital stay, reduced blood loss, and improved component alignment. A retrospective study was carried out to evaluate the difference in post-operative pain outcomes between conventional and computer-assisted navigation knee arthroplasty in a high volume setting. Computer-assisted surgery may be more painful because of the extra pin holes required for the navigation. The amount of anti-emetic use between the two groups was also looked at as evidence exists that greater anti-emetic is used if pain levels are greater.

All the navigated arthroplasty operations were performed by one of two surgeons in a single hospital using a uniform surgical approach and navigation system. A single type of prosthesis was used in the conventional group. In the first part of the study, the navigated group consisted of 87 patients and the conventional group of 40 patients (total = 127 cases). In the second ‘antiemetic use’ study, the navigated group consisted of 71 patients and the conventional group of 39 (total = 110). The analgesic and anti-emetic use was collated for the 72-hour post-operative period. This was chosen so that any analgesic influence of the anesthetic would have been negated over this period.

Pain scores were measured over the 72 hour period at regular intervals using a visual analogue scale. Patients in the navigated group seemed to report less pain in the first 24 hours but this was later reversed. Interestingly, their pain scores were more constant during this period, whilst the conventional group exhibited greater variability. The actual difference in pain scores between the two groups was however not significant (p=0.33).

The amount of opioid used by patients in each group was the primary factor used to see if a difference exists between the two procedures. The assumption was made that a correlation exists between opioid usage and pain. The total opioid usage was calculated by using referenced opioid conversion calculations for intravenous and oral forms of morphine including weaker opioids such as codeine and tramadol.

The average opioid used in the conventional group was 164.8 mg whilst in the navigated it was 173.7mg. However using the Student’s t-test this difference was not significant with a p value = 0.69. The percentage of patients requiring opioid greater than 300mg in 72 hours was actually greater in the conventional group (15% vs 12.6%).

The average antiemetic use looking initially at cyclizine was 57.7mg in conventional and 50.4mg in the navigated. This difference was also not significant (p=0.59).

On analysis of the tourniquet times between the groups it was noted that the average time for a conventional operation was 89.6 minutes whilst it was 88.6 minutes in the other. This is in contrast to previous findings and it seems that the learning curve is improving at least in this high volume setting.

This paper suggests that there is no difference between the two groups with respect to pain experienced in the post-operative period.

The purpose of this study was to assess the stability of a developmental pelvic reconstruction system which extends the concept of triangular osteosynthesis with fixation anterior to the lumbosacral pivot point. An unstable Tile type-C fracture, associated with a sacral transforaminal fracture, was created in synthetic pelves. The new concept was compared with three other constructs, including bilateral iliosacral screws, a tension band plate and a combined plate with screws. The pubic symphysis was plated in all cases. The pelvic ring was loaded to simulate single-stance posture in a cyclical manner until failure, defined as a displacement of 2 mm or 2°. The screws were the weakest construct, failing with a load of 50 N after 400 cycles, with maximal translation in the craniocaudal axis of 12 mm. A tension band plate resisted greater load but failure occurred at 100 N, with maximal rotational displacement around the mediolateral axis of 2.3°.

The combination of a plate and screws led to an improvement in stability at the 100 N load level, but rotational failure still occurred around the mediolateral axis. The pelvic reconstruction system was the most stable construct, with a maximal displacement of 2.1° of rotation around the mediolateral axis at a load of 500 N.
