Aim

To investigate any intra-operative alteration in management in those patients who had a pre-operative echocardiogram, a retrospective study for one year (March 2004 to February 2005) was carried out at West Middlesex University Hospital.

Percutaneous A1 pulley release is being increasingly used as an alternative to open surgical release and injection of local steroids for the treatment of the trigger digit. We treated 43 patients, average age 57 years (range12-78). All trigger digits were grade III-IV (Quinnell classification). A mean duration of pre-operative symptoms was 7.3 months (range 2-13 months). A percutaneous release was performed with a 19-gauge hypodermic needle under local anaesthesia in the outpatient setting. All patients were evaluated with respect to clinical resolution of symptoms and general satisfaction.

We report a 97% successful release and only one case of incomplete release. A result in terms of abolishing triggering was immediate and patient acceptance was excellent. By two weeks, all the patients had no pain at the operative site. After a mean follow-up of 30.2 months (range12-50), there had been no recurrences. There were no digital nerve injuries, flexor tendon injuries, and infections.

The percutaneous release is a safe and effective technique, which provides significant cost savings. The time from onset of symptoms and grading prognostically is significant and affects the treatment outcome. We recommend the percutaneous technique for typical cases of trigger finger with a palpable nodule and reproducible mechanical triggering. This technique can be the treatment of choice for the established trigger finger (grade III and IV) with symptoms of more than few months' duration. The open technique is reserved for complicated cases such as florid tenosynovitis, locked digit, failed percutaneous release or those involving the thumb.

Ostoearthritis of the trapeziometacarpal (TMC) joint, the key joint in thumb opposition, is one of the most common diseases involving the hand, especially among middle-aged and elderly women, and can seriously impair overall hand function.

Material and Methods: The purpose of this study was to analyze our experience in the treatment of trapezio-metacarpal (TMC) osteoarthritis with a cemented surface replacement arthroplasty (SR Avantis prosthesis). We did a retrospective study of 34 patients with 43 hands operated on with this technique, with a follow-up evaluation of 36 months. We analyzed the preoperative stage, the postoperative clinical results, measured the radiographic changes found at the end of the study. For outcome, Quick-DASH (Disabilies of the Arm, Shoulder and Hand Score) scores was used.

A Jamar dynamometer was used to assess the grip and pinch strengths which showed a 63% of recovering of the grip strength. Overall survival after a mean follow up of 36 months was 93%. At final follow up mean Quick DASH score was 27.4 Radiological review of the surviving joints showed subsidence of trapezial component in 4 joints and further lucencies in 3 joints. However, these patients had good hand function and grip strength. No sign of osteolysis was seen in any of the cases. We found that the radiological findings did not correlate with clinical findings. Satisfaction rate was 26 good to excellent, with 5 fair and 3 poor.

Conclusion: The three years results of the SR joint replacement are promising with satisfactory functional outcome despite some radiological findings.

Background: The standard diagnostic approach in patients suspected of having pulmonary embolism starts with D-dimer and perfusion-ventilation lung scanning. If the resulting scan is not diagnostic, pulmonary angiography will perform.

Aims: This study evaluates the effectiveness of D-dimer as a screening tool for Pulmonary Embolism (PE) and to determine the accuracy and potential clinical utility of VQ scan in the diagnosis of pulmonary embolism in orthopaedic trauma patient.

Methods: We retrospectively reviewed 757 consecutive trauma admissions involving lower extremity and spinal injuries over 12 months and identified 20 patients with symptoms mimicking PE, without typical clinical symptoms, which underwent rotten investigations for PE (ABG, Blood test, D dimer, Chest X-ray and VQ scan).

Plasma D-dimer levels were measured as a prerequisite test in all patients before undergoing VQ scan to confirm the absence of PE. All patients had either mechanical, such as foot pumps, or chemical DVT prophylaxis.

Results: The mean age was 65 (ranging from 45–88) years, there were 11 female and 9 male. D-dimer levels in the postoperative or post traumatic period were elevated. Mean value was 3.63 (sd=2.72, range 0.60–14.34), Comparing D-dimer levels between those treated operatively (14 patients) and those treated conservatively (6 patients) we found that both groups displayed the same trend; however levels were higher following surgery.

The classical triad of dyspnoea, pleuritic chest pain and haemoptysis occurred in only 2 patients. Signs of DVT were present in 3 patients. The electrocardiographs were normal in only 4 patients, though changes particularly suggestive of PE (S1Q3T3, Right bundle branch block or right heart strains) were absent in all of the patients. Chest X-ray changes were of limited value. None showed any of the supposedly characteristic changes.

All of the patients had a VQ scan were started on chemical treatment for PE and non of them had definite PE, 12 the patients had probable PE Those patient with probable scan were not subsequently given anticoagulants owing to their medical conditions

Conclusion: The D-dimer level is never normal (< 0.5mg/l), following total trauma, and so cannot exclude a DVT or PE. The level it raises to is indistinguishable form that seen in the population with a PE and so cannot identify those patients in whom further investigation is warranted. VQ scan is not a definitive diagnosis we should rely more and more on a CT Angiography scan for the diagnosis of PE in this group of patients. This should be organised by medical team, especially with shortening of training time, to avoid wasting of resources and time which are of paramount. Requesting a D-dimer test in this population wastes time and resources and is of no benefit

Background: To assess the cosmetic advantage of costotomy at the angle of the ribs on the convexity of a curve in the management of Adolescent Idiopathic scoliosis. Whilst modem segmental correction produces gratifying improvement in Cobb-angle and, to some extent rotation, rib asymmetry often remains as a concern for patients. Performing costotomy at the angle of the rib at the same time as corrective surgery can improve the cosmetic appearance significantly. It avoids any further scars or surgery, and is associated with minimal complications, the main one being pneumothorax and the requirement of a chest drain.

Methods: Retrospective review of 50 patients. This has been a standard practice and this presentation reports on 50 patients treated in Preston with a variety of corrective devices; we have assessed results radiologically, with cosmetic acceptability by the patient and surface topographical analysis.

Results: Significant improvement occurs at the time of costotomy as the ribs drop from their arched position after the coronal deformity has been improved

Conclusion: The addition of costotomy at the time of primary surgery for Adolescent Idiopathic Scoliosis leads to minimal complications. Significant improvement occurs at the time of costotomy as the ribs drop from their arched position after the coronal deformity has been improved. This is maintained in the post-operative period by moulding of the brace.

Elevated plasma levels of D-dimer have been found to be a useful screening tool in the diagnosis of deep venous thrombosis (DVT) in the general population. In the post operative setting however their role is less clear. The majority of NHS trusts use D-dimer as a prerequisite test prior to radiological imaging to diagnose DVT.

Aims and method: This study evaluates the effectiveness of D-dimer as a screening tool for DVT in the postoperative period following total hip and knee arthroplasty.

Plasma D-dimer levels were measured pre operatively and on post operative days 1, 3, 5, and 7 in 78 patients undergoing primary total hip or knee arthroplasty. On day 7 patients underwent bilateral duplex ultrasound scanning in order to confirm the absence of DVT. All patients wore pneumatic foot pumps for DVT prophylaxis. Chemical thromboprophylaxis was not used.

Results: D-dimer levels in the post operative period were characterized by a double peak, on days 1 and 7. Mean day 1 value 3.63 (sd=2.72), mean day 7 value 2.83 (sd=1.58). Mean values on days 3 and 5 were 2.52 (sd=2.26) and 2.45 (sd=1.41)

Comparing D-dimer levels between hip and knee arthroplasty we found that both groups displayed the same trend in post operative D-dimer levels; however levels were significantly higher following knee replacement.

We compared D-dimer levels of these patients with a second group of 43 patients who had a confirmed DVT following hip or knee arthroplasty. The mean D-dimer level in this group was 2.20 (sd=0.98 or range 0.80 – 4.46). This group was subdivided into two groups, those with D-dimer samples before day 8 and those after. We found a significant difference between the groups (p=0.01). Mean < day 8 = 2.70. Mean ³ day 7 = 1.97.

The group of patients with Confirmed DVT before day 8 were compared with those free of clot. There was no significant difference found between the D-dimer levels of the two groups. (p=0.37).

Conclusion: The D-dimer level is never normal (< 0.4mg/l), in the week following total hip or knee replacement and so cannot exclude a DVT. The level it rises to is indistinguishable form that seen in the population with a DVT and so cannot identify those patients in whom further investigation is warranted. Requesting a D-dimer test in this population wastes time and resources and is of no benefit.

Soft tissue tumours on the sole of the foot are rare and difficult to diagnose, we report a series of five patients who presented with a late diagnosis of a soft tissue tumour on the soles of their feet.

We reviewed the notes of five patients who presented with lesions on the soles of their feet. There were 3 males and two females with an age range from 35yrs to 78 yrs. Our results showed that there was at least a one year delay in their diagnosis from their initial symptoms. They all sought medical treatment late, and were all originally diagnosed with benign lesions at their first presentation. All but one, were found to have malignant lesions on biopsy which required surgical excision. As a consequence of the delay in their presentation and diagnosis, there was also a delay in their treatment.

Our conclusions are that tumours on the soles of the feet are difficult to diagnose and almost invariably present late.
