The use of ultrasound-guided wire localisation of lesions is not well described in the orthopaedic literature. We describe a case of an impalpable schwannoma of the femoral nerve and another of sacroiliitis with an associated pelvic abscess. In both, surgical localisation was difficult. Peri-operative ultrasound-guided wire localisation was used to guide surgery and minimise tissue damage, thereby optimising the results and recovery of the patient.

Clinical, haematological or economic benefits of post-operative blood salvage with autologous blood re-transfusion have yet to be clearly demonstrated for primary total hip replacement. We performed a prospective randomised study to analyse differences in postoperative haemoglobin levels and homologous blood requirements in two groups of patients undergoing primary total hip replacement.

A series of 158 patients was studied. In one group two vacuum drains were used and in the other the ABTrans autologous retransfusion system. A total of 58 patients (76%) in the re-transfusion group received autologous blood. There was no significant difference in the mean post-operative haemoglobin levels in the two groups. There were, however, significantly fewer patients with post-operative haemoglobin values less than 9.0 g/dl and significantly fewer patients who required transfusion of homologous blood in the re-transfusion group. There was also a small overall cost saving in this group.

We reviewed 234 benign solitary schwannomas treated between 1984 and 2004. The mean age of the patients was 45.2 years (11 to 82). There were 170 tumours (73%) in the upper limb, of which 94 (40%) arose from the brachial plexus or other nerves within the posterior triangle of the neck. Six (2.6%) were located within muscle or bone. Four patients (1.7%) presented with tetraparesis due to an intraspinal extension.

There were 198 primary referrals (19 of whom had a needle biopsy in the referring unit) and in these patients the tumour was excised. After having surgery or an open biopsy at another hospital, a further 36 patients were seen because of increased neurological deficit, pain or incomplete excision. In these, a nerve repair was performed in 18 and treatment for pain or paralysis was offered to another 14.

A tender mass was found in 194 (98%) of the primary referrals. A Tinel-like sign was recorded in 155 (81%). Persistent spontaneous pain occurred in 60 (31%) of the 194 with tender mass, impairment of cutaneous sensibility in 39 (20%), and muscle weakness in 24 (12%).

After apparently adequate excision, two tumours recurred. No case of malignant transformation was seen.
