Aims

This study aimed to evaluate rasterstereography of the spine as a diagnostic test for adolescent idiopathic soliosis (AIS), and to compare its results with those obtained using a scoliometer.

To assess the sustainability of our institutional bone bank, we calculated the final product cost of fresh-frozen femoral head allografts and compared these costs with the use of commercial alternatives. Between 2007 and 2010 all quantifiable costs associated with allograft donor screening, harvesting, storage, and administration of femoral head allografts retrieved from patients undergoing elective hip replacement were analysed.

From 290 femoral head allografts harvested and stored as full (complete) head specimens or as two halves, 101 had to be withdrawn. In total, 104 full and 75 half heads were implanted in 152 recipients. The calculated final product costs were €1367 per full head. Compared with the use of commercially available processed allografts, a saving of at least €43 119 was realised over four-years (€10 780 per year) resulting in a cost-effective intervention at our institution. Assuming a price of between €1672 and €2149 per commercially purchased allograft, breakeven analysis revealed that implanting between 34 and 63 allografts per year equated to the total cost of bone banking.

The “Universal Protocol” (UP) was launched as a regulatory compliance standard by the Joint Commission on 1st July 1 2004, with the primary intent of reducing the occurrence of wrong-site and wrong-patient surgery. As we’re heading into the tenth year of the UP implementation in the United States, it is time for critical assessment of the protocol’s impact on patient safety related to the incidence of preventable never-events. This article opens the debate on the potential shortcomings and pitfalls of the UP, and provides recommendations on how to circumvent specific inherent vulnerabilities of this widely established patient safety protocol.

Introduction. 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. Materials/Methods. 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. Results. The biopsy tract was easily identifiable in all 56 patients (100%) by junior and senior orthopaedic surgeons. The mean duration between the skin tattoo and surgery was 68 days (range 12–299 days). Radiotherapy and chemotherapy did not influence the identification of the tattoo site. Conclusions. Tattooing the skin with India ink enabled the surgeon to accurately excise the biopsy tract. We recommend this technique of tattooing the biopsy site with India ink as it is safe, easily recognisable and aids in accurate excision of the tract and the tattoo site

Local recurrence along the biopsy track is a known complication of percutaneous needle biopsy of malignant musculoskeletal tumours. In order to completely excise the track with the tumour its identification is essential, but this becomes increasingly difficult over time. In an initial prospective study, 22 of 45 patients (48.8%) identified over a three-month period, treated by resection of a musculoskeletal tumour, had an unidentifiable biopsy site at operation, with identification statistically more difficult after 50 days. We therefore introduced the practice of marking the biopsy site with India ink. In all 55 patients undergoing this procedure, the biopsy track was identified pre-operatively (100%); this difference was statistically significant. We recommend this technique as a safe, easy and accurate means of ensuring adequate excision of the biopsy track.

Percutaneous biopsies can lead to seeding of tumour cells along the biopsy tract. 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. We conducted a prospective study involving 45 patients who had tissue biopsies for bone and soft tissue tumours between February and May 2008. All the biopsies were performed by consultant radiologist under ultrasound or CT guidance. Case note analysis, patient history and examination at the time of surgery were used to collect data. 23 of 45 patients had accurate identification of the biopsy tract by the surgeon at the time of excision. The mean time between biopsy and excision was 52 days (range 6–140). 22 of 45 patients had unidentifiable biopsy site, with the mean time between biopsy and excision being 98 days(range 13–164) p=0.0004(paired t test). All 4 patients who received post-biopsy radiotherapy had unidentifiable biopsy site tract (mean duration 104 days) and 11 of the 18 patients who underwent neoadjuvant chemotherapy had an unidentifiable biopsy tract (mean duration 108 days). We concluded that identification of biopsy site was more difficult after 50 days, especially in patients who underwent radiotherapy and chemotherapy. Following this study, all the patients who had biopsies of tumours had the site marked with India ink tattoo. We, then prospectively reviewed 36 patients between July and September 2010 who underwent excision of bone and soft tissue tumours and had their biopsy sites marked with India ink tattoo. After needle biopsy, one drop of the dye was applied at the site of the biopsy. This was taken up by capillary action beneath the dermis and remained present until the patient returned for their definitive surgery. The biopsy site was easily identifiable by the patients and the operating surgeon in all 36 patients. The mean time between biopsy and surgery was 77 days (range 10–299 days). Tattooing of the skin enabled the surgeon to accurately excise the biopsy tract along with the tumour. We recommend this technique of tattooing of the biopsy site with India ink, as it is safe, easily recognisable and permits accurate excision of the tract (including the tattoo), therefore preventing biopsy tract recurrence

Objectives

Surgical marking during tendon surgery is often used for technical and teaching purposes. This study investigates the effect of a gentian violet ink marker pen, a common surgical marker, on the viability of the tissue and cells of tendon.

Introduction: Seeding of bone or soft tissue tumour along the biopsy tract is a known complication of percutaneous biopsies. Correct surgical management requires preoperative Identification and excision of the biopsy tract at time of surgery. We aim to audit how well biopsy tract sites can be identified preoperatively and investigate factors influencing their Identification. Method: Prospective audit of patients who had tissue biopsies for bone and soft tissue tumours at the RNOH Stanmore and presented for surgery between February and April 2008. Case note analysis, patient history and examination at the time of surgery used to collect data. Results: 13/23 patients had their biopsy tract site accurately identified preoperatively, with a mean time gap of 43 days (6–118) between biopsy and excision. In 10/23 patients the biopsy site could not be accurately identified preoperatively. In these patients the mean time between biopsy and excision was 106 days (55–158) (p=< 0.05). 7 patients had neoadjuvant chemotherapy with a mean time gap of 110 days; in 5/7 the tract site was unidentifiable. One patient had preoperative radiotherapy and the biopsy site was unidentifiable. Discussion: This audit has shown that Identification of the biopsy site is more difficult after 40 days. In order to ensure accurate Identification of the biopsy site an Indian ink tattoo should be considered at time of biopsy. It may be particularly advisable for patients who are likely to require neoadjuvant chemotherapy or preoperative radiotherapy. On this basis we would recommend that all patients have the biopsy site marked at the time of biopsy and a further audit will be carried out to evaluate this change in practice

We tested prospectively for hepatitis C virus (HCV) in one orthopaedic surgeon's operative practice for one year. Of 425 consecutive patients, 19 (4.5%) were positive for HCV infection using a second-generation screening assay. The highest correlation with a positive test was the presence of tattoos and the second highest was intravenous drug abuse, but only after a second interview, since most patients did not report this risk on the initial questionnaire. Based on the criteria of the US Public Health Services algorithm, nine (47%) of the patients with a positive initial screening test or 2.2% of the 425 patients, had hepatitis C (both anti-HCV-positive and elevated alanine aminotransferase). In this group of nine, the presence of tattoos had the highest and intravenous drug abuse the second highest correlation, also after the second interview. There is no vaccine available for the prevention of HCV infection, and prophylactic immunoglobulin therapy has no proven value for primary exposure
