Positive culture in allograft ACL-reconstruction: what to do?

The transmission of disease or infection from the donor to the recipient is always a risk with the use of allografts. We carried out a research study on the behavioural pattern of implanted allografts, which were initially stored in perfect conditions (all cultures being negative) but later presented positive cultures at the implantation stage. Because there is no information available on how to deal with this type of situation, our aim was to set guidelines on the course of action which would be required in such a case. We conducted a retrospective study of 181 patients who underwent an ACL reconstruction using BPTB allografts. All previous bone and blood cultures and tests for hepatitis B and C, syphilis and HIV were negative. An allograft sample was taken for culture in the operating theatre just before its implantation. The results of the cultures were obtained 3-5 days after the operation. We had 24 allografts with positive culture (13.25%) after the implantation with no clinical infection in any of these patients. Positive cultures could be caused by undetected contamination while harvesting, storing or during manipulation before implantation. The lack of clinical signs of infection during the follow-up of our patients may indicate that no specific treatment-other than an antibiotic protocol-would be required when facing a case of positive culture of a graft piece after its implantation.

Therapeutic embolisation for postoperative haemorrhage after total arthroplasty of the hip and knee.

We describe three cases of postoperative haemorrhage, two after total hip and one after total knee replacement, treated by percutaneous embolisation. After diagnostic angiography, this is the preferred method for the treatment of postoperative haemorrhage due to the formation of a false aneurysm, after hip or knee arthroplasty. This procedure, carried out under local anaesthesia, has a low rate of complications and avoids the uncertainty of further surgical exploration.

Femoral anteversion osteotomy for the treatment of hip dislocation in Down syndrome: long-term evolution.

We propose a femoral desrotational osteotomy to antevert the femoral head associated with plication of the anterior and superior capsule for treatment in the early stages of hip dislocation in Down syndrome. Eight patients (10 hips) with Down syndrome and hip dislocation were reviewed. Five children (seven hips) were operated. We used the proposed surgical technique in three patients (four hips). The average follow-up was 11 years (range, 5-16 years). No infections or complications were observed. In our short experience, this is the recommended procedure in the early stages of hip dislocation in Down syndrome.

[Congenital synostoses of the tarsus. Concept, classification, diagnosis and therapeutic approach].

The incidence of congenital tarsal coalition is about 1%. It is recognized as the main etiology of painful, rigid flatfoot in the pediatric population. Talonavicular (50%) and talocalcaneal (40%) coalition are the most common presentation. We must suspect a tarsal coalition in a child with mechanical pain and shoes deformity. Rigid and painful planovalgus deformity are found in physical exam which led to describe in the pass this entity as peroneal spastic flatfoot. Lateral and oblique (35 degrees-45 degrees) radiographs must be practice to observe the coalition. The presence of a beak in the head of the talus or a half moon condensation image as the result of the superposition of the talus over the calcaneus are commonly described. CT-scan is also useful to delineate the size of the coalition and its location. Resection of the bar is the surgical treatment of choice. Excision of the coalition and interposition of fat or a graft must be tried in young patients in order to preserve foot biomechanical properties and to avoid long term problems associated with arthrodesis. Triple arthrodesis or subtalar arthrodesis must be used in older patients with degenerative signs in radiographs or in those cases of multiple coalition or if resection has failed.

[Cervical spondylodiscitis].

Eighty patients were treated for spondylodiscitis with the cervical spine involved in nine cases. Conservative treatment was applied in seven cases with Minerva jacket and antibiotics, and surgical treatment was applied in severe, rapidly, progressive, complicated cases and in patients with involvement of nervous system (two cases). The good and satisfactory results in both group were similar. These results show that when the indications are properly established, both conservative and operative methods have satisfactory results.

[Cauda equina syndrome due to giant disc herniation].

In cases of acute or progressive development in a few hours of bilateral sciatica, severe foot and occasional quadriceps weakness and/or retention or incontinence of urine with perineal hypalgesia or anesthesia, acute compression of the cauda equina should be suspected, which is usually due to a lumbar disc herniation. Cauda equina syndrome requires emergency spinal surgery. To identify and confirm this syndrome by MR, Ismanoatory. Early surgical decompression must be achieved. Decompression within 24-48 hours significantly improves the neurological and urological outcome. We present the case of a patient who had previously been treated for low back pain who developed a cauda equina syndrome a few days later.
