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
One of the basic principles in the primary survey of a trauma patient is immobilisation of the cervical spine till cleared of any injury. Lateral cervical spine radiograph is the gold standard initial radiographic assessment. More than often additional radiographs like the Swimmer's view are necessary for adequate visualisation of the cervical spine. How good is the Swimmer's view in visualisation of the cervical spine after an inadequate lateral cervical spine radiograph? 100 Swimmer's view radiographs randomly selected over a 2 year period in trauma patients were included for the study. All the patients had inadequate lateral cervical spine radiographs. The radiographs were assessed with regards to their adequacy by a single observer. The criteria for adequacy were adequate visualisation of the C7 body, C7/T1 junction and the soft tissue shadow.Background
