Local recurrence of tumours along the biopsy tract is a known complication of percutaneous closed needle biopsy. Correct surgical management requires preoperative identification and excision of the biopsy tract at time of surgery. These tracts become increasingly difficult to identify with time, leading to risk of inadequate excision of the biopsy tract and recurrence of the tumour at the biopsy site. In a prospective study conducted at our institution, 22 of the 45 patients with musculoskeletal tumours (49%) had unidentifiable biopsy sites, with a mean duration between biopsy and definite surgery being 98 days (range 13–164 days). We concluded that identification of the biopsy site was more difficult after 50 days. Radiotherapy related scar formation and the longer time duration between biopsy and definite surgery in patients requiring neoadjuvant therapy made identification more unlikely. Consequently, all patients received India ink skin tattoo to mark the biopsy site at the time of the needle biopsy. 56 patients were then prospectively reviewed on the day of surgery to identify the biopsy site.Introduction
Materials/Methods
The aim of this study was to see if the evaluation of the initial postoperative radiograph following primary knee and hip arthroplasty correlated with clinical outcome at five years postoperatively. Using our institution database we identified forty-nine hip replacements and fifty-two knee replacements performed between 2000 and 2006. All the patients underwent postoperative radiographs one day after surgery and clinical evaluation up to at least five years postoperatively. A consultant radiologist evaluated the radiographs for alignment and component position. The hip arthroplasty patients were assessed clinically using the Harris hip score, Oxford hip score, and the Western Ontario and McMaster Universities Osteoarthritis index (WOMAC). The knee arthroplasty patients were assessed using the Knee Society score, Oxford knee score, and the WOMAC score.Introduction
Methodology
To construct and validate a simple patient related outcome measure scheme to quantify the disability caused by Dupuytren's Disease thus enabling prioritisation of treatment, allow reliable audit of surgical outcome and support future research. The Southampton Dupuytren's Scoring System (SDSS) was developed in a staged fashion according to the recommendations of Derby Outcomes Conference. item generation from questionnaire filled in by 20 patients; item reduction to create a 20-question proforma; Internal consistency (Cronbach's alpha) Test-retest (3 week interval testing on 61 patients) Field management was used to assess the user friendliness of the scoring system. Sensitivity to change Standardised response mean Construct validity: ability of the SDSS to measure what it is supposed to measure. comparing SDSS with QuickDASH (Disability of Arm, Shoulder and Hand)Aim
Methods
There is very limited literature available on the use of prosthetic replacement in the treatment of primary and secondary tumours of the radius. In the past these were treated with vascularised and non-vascularised autografts which had associated donor site morbidity, problems of non union, graft or junctional fractures and delayed return to function. Our study is a mid to long term follow-up of implant survivorship and the functional outcome of metal prosthetic replacement used for primary and metastatic lesions of radius. We had 15 patients (8 males:7 females) with a mean age of 53 years. 8 patients underwent proximal radial replacement, 2 with mid-shaft radial replacement and 6 patients had distal radial replacements with wrist arthrodesis. The indications for replacement included metastatic lesions from renal cell carcinoma, primary giant cell tumours, ewings' sarcoma, chondroblastoma, radio-ulnar synostosis and benign fibrous histiocytoma. The average follow up was 5 years and 6 months (range 3 months - 18 years). Four patients died as a result of dissemination of renal cell carcinoma and two patients were lost to follow-up. There were no complications with the prosthesis or infection. Clinically and radiographically there was no loosening demonstrated at 18 years with secure fixation of implants. Two patients developed interossoeus nerve palsies which partially recovered. Functional outcomes of the elbow were assessed using the Mayo performance score with patients achieving a mean score of 85 postoperatively (range 65-95). All but one patient had full range of motion of the elbow. The patient with radio-ulnar synostosis had a 25 degree fixed flexion pot-operatively. Although the distal radial replacements had decreased range of movements of the wrist due to arthrodesis, they had excellent functional outcomes. Only one patient required revision surgery due to post-traumatic loosening of the implant. Our results of the use of endoprosthetic replacement of radius in the treatment of tumours are encouraging with regards to survivorship of the implant and functional outcome. This type of treatment results in an early return to daily routine activties, good functional outcome and patient satisfaction.
