Anterior scoliosis surgery is associated with potentially significant intra-operative blood loss, requiring homologous transfusion either intra- or post-operatively. Blood loss in this type of surgery correlates with surgical &
anaesthetic techniques. In our centre the development of specific anaesthetic techniques as well as the routine use of Cell Salvage has dramatically reduced the rates of homologous blood transfusion. Currently specific indications for the use of the Cell Saver in Anterior Scoliosis have not been proven. Previous studies have commented on the beneficial aspects of recovered autologous transfusion for Orthopaedic patients in general, whilst others have shown a negligible advantage specifically in anterior thoracolumbar fusion surgery. In order to assess the cost-effectiveness of the techniques used in Anterior Scoliosis Surgery we carried out a retrospective study of 180 consecutive patients, all of whom underwent instrumented anterior scoliosis correction between July 2000 and September 2004. A cell saver was used in all the cases, and hospital data (including haematological indices and number of levels fused) was collected. The median age of the study cohort was 11.2 years (range 7 – 64), and the male:female ratio was 1:8.4. The average preoperative haemoglobin in all patients was 12.7g/dl and the average postoperative haemoglobin was 9.8g/dl. In total the rate of homologous transfusion requirement was 1 unit per 9.1 patients. Results show that homologous transfusion was required in less than 11% of all patients. This is better than previously published rates of transfusion in similar procedures. The range of volume of intra-operatively salvaged cells was 200 to 770mls. There was no correlation between the number of levels fused (extent of scoliosis corrective surgery) and units transfused. Our experience shows that the use of Salvaged Autologous Blood Transfusion in anterior scoliosis surgery has an important role in reducing the incidence of postoperative anaemia and homologous transfusion requirements.
Rotator cuff pathology is common in orthopaedic patients. However, there are still debates about the best way of treating those patients. We present the clinical experience from our Unit. We present 85 patients who had arthroscopic or arthroscopically assisted shoulder surgery for full thickness rotator cuff tears between 1994 and 2001. Their medical records and radiological investigations were reviewed, and the management as well as the outcome of their treatment were recorded. The aim was to review those patients and determine if optimum assessment and management was implemented to them. There were 47 male and 38 female patients with average age 58.8 years and weight 79.9 kg, 32 of the patients reported trauma prior to their symptoms. 63 patients had MRI scan and they had average 2.6 years of symptoms and 2.4 steroid injections before their operative management. 27 patients had arthroscopic and 58 mini open rotator cuff repair. From those with recorded pain management 32 patients had interscalene block and 21 infiltration with local anaesthetic. Their average hospital stay was 1.4 and 1.8 days for the arthroscopic and mini open repairs respectively. In 69 (77.7%) patients the result was considered overall satisfactory; 8 (9.4%) patients had temporary shoulder stiffness and/or pain, which were treated conservatively with steroid injections and physiotherapy. 11 (12.9%) of the patients required reoperation, 5 from which required cuff resuturing and 4 manipulations under anaesthetic for postoperative stiffness. 3 patients (3.5%) had other than shoulder complications including CVA, chest infection, and CTS. Rotator cuff surgery remains a challenge where often the working surgical plan is altered intraoperatively and tissue quality is of major importance for the final outcome. Arthroscopy has reduced patient’s hospital stay and rehabilitation time. However, a not durable repair, or postoperative stiffness can be a potential risk complicating the surgical result. In this study it is demonstrated that treatment of patients with rotator cuff disease is still a challenge, time in hospital is reduced with arthroscopic management, but the overall risk for reoperation/MUA either for not durable previous repair or postoperative stiffness was still quite high (12.9%).
Rotator cuff or long head of biceps tendon tears are common in patients with degenerative shoulder rotator cuff disease. Most often they are investigated with an MRI scan. Diagnosis prior to surgery is useful for the appropriate surgical planning. We present 63 consecutive patients who had arthroscopic shoulder surgery and prior to that had MRI investigation between 1994 and 2001. Their medical records were reviewed; arthroscopic operative findings as well as the report of the MRI scan were recorded and compared retrospectively. The aim of our study was to assess the accuracy of MRI findings comparing the arthroscopic ones regarding rotator cuff and biceps tendon pathology. There were 63 patients with mean age 58 years. All of these had MRI scan investigation and the waiting time prior to surgery was 10 months. It was found that there were 6 false (−)ve, 1 false (+)ve and two cases with full thickness cuff tears which were reported as probable tears. Further to that, there were 11 frayed biceps tendons, 8 partially ruptured, 3 subluxed, 4 complete ruptures and 1 SLAP lesion. All biceps lesions were not commented in the MRI scan reports. MRI scan is very sensitive detecting soft tissue pathology in shoulder investigation. However, even on that basis, rotator cuff and in particular biceps tendon pathology can be missed. The shoulder arthroscopy is the best method to accurately diagnose those lesions. However, it should be noted that often the surgeon has got to alter to working surgical plan in order to address the problem intraoperatively. In this study it is demonstrated the MRI scan often misses rotator cuff or long head of biceps tendon pathology. The most sensitive method for the diagnosis of it is the shoulder arthroscopy, which address its treatment in the same time.
