Pigmented villonodular synovitis is a monoarticular proliferative process most commonly involving the synovium of the knee joint. There is considerable debate with regards to diagnosis and effective treatment. We present our experience of managing PVNS of the knee joint over a 12 year period. Twenty-eight patients were reviewed. MRI was used to establish recurrence in symptomatic patients rather than routine screening and to identify posterior disease prior to surgery. Eight patients had localised disease and were all treated with open synovectomy and excision of the lesion, with no evidence of recurrence. Twenty patients had diffuse disease, eight treated arthroscopically and twelve with open total synovectomy. Nineteen patients (95%) had recurrence on MRI, however, only five (25%) had evidence of clinical recurrence. There were no significant complications following arthroscopic synovectomy. Open synovectomy, in contrast, was associated with three wound infections and two thrombo-embolisms. Three patients had Complex regional pain syndrome. We believe diffuse disease should be treated with arthroscopic synovectomy which is associated with minimal morbidity and can be repeated to maintain disease control. Radiotherapy is helpful in very aggressive cases. TKR was used when there was associated articular erosion.
Shoulder instability is a common cause of morbidity amongst Professional Rugby Union players. This study explores whether the risk of shoulder dislocation is associated with innate shoulder laxity. A randomised controlled study was completed in which all the Premiership Rugby Clubs in England were visited in 2006. 169 professional rugby players (mean age 25.1 years) with no history of instability in either shoulder were assessed and 46 injured players with one shoulder with a history of Bankart lesion or dislocation (mean age 27.5 years) also took part in this study. Shoulder laxity was measured by dynamic ultrasound. Anterior, posterior and inferior translations were measured in both shoulders for healthy players and the uninjured shoulder only for injured players.Objective
Methods
Total elbow arthroplasty (TEA) has been shown to be a treatment option for elderly patients with complex distal humeral fractures and osteoporotic bone. The published results have often included rheumatoid patients who traditionally would be expected to do well from elbow arthroplasty. Only short-term results have been published using this technique in non-rheumatoid patients. The current study contains the largest number and longest follow-up of non-rheumatoid patients whose fractures have been treated with a non-custom TEA. In total there were 26 patients, mean age 72 years, 22 female and 4 male, 25% dominant arm. The mean follow-up was of 5 years. There was 1 case of loosening, 1 radial nerve palsy and 2 cases of heterotrophic ossification. At final review the mean range of flexion/extension was 97.5 degrees and the mean range of pronation/supination was 151.75 degrees. The mean Mayo Elbow Performance score was 92. We would suggest that TEA provides a very satisfactory outcome in elderly patients with complex distal humeral fractures, the benefit of which can be observed at a mean of 5 years.
Frozen Shoulder is a common condition which causes significant morbidity in people of working age. The 2 most popular forms of surgical treatment for this condition are Manipulation under Anaesthesia (MUA) or MUA plus Arthroscopic Capsular Release (ACR). Both treatment modalities are known to give good results, but no-one has compared the two to see which is better. To compare the outcome in patients with primary frozen shoulder, who are treated by either MUA or MUA plus ACR.Background
Aim
The use of shoulder ultrasound in clinic is a way of decreasing the time patients have to wait til definitive treatment is started. Although ultrasound is used in clinic by some surgeons, we are not aware of anyone specifically looking at the total cost implications and the impact on waiting times. We therefore prospectively assessed the outcome of a one-stop shoulder assessment service set up by a new Consultant Orthopaedic Surgeon in a busy unit. All new patients were assessed by the Consultant, who then performed an ultrasound if indicated. Treatment or further investigation was then instituted based on the findings. The time taken and accuracy of the scans, the number of patients seen, impact on waiting times, total savings and patient satisfaction were assessed. We based cost calculations from data that included capital, structural, maintenance and staffing costs gained from the Department of Health and the hospital management. We found that 65% of all shoulder patients required ultrasound, and these were performed in an average of 2.7 minutes, with no significant overrunning of the clinic. The sensitivity for the detection of full thickness rotator cuff tears was 88% and specificity was 89%. Four patients needed further ultrasonography by a specialist musculoskeletal radiologist. All patients reported high satisfaction rates. We calculated the cost saving over a year of two shoulder surgeons performing ultrasound in a similar setting was between £200,000 and £500,000 depending on the figures you used. We believe ultrasound is a quick, easy, cheap imaging process for the diagnosis of soft tissue shoulder diseases. When performed at the first consultation by the surgeon it offers the advantages of high patient satisfaction rates, shorter waiting times, and significant cost savings. Should all shoulder surgeons be performing ultrasound in clinic?
Intra-articular distal humeral fractures in the elderly are difficult to treat. There is evidence in the literature to support the use of both Open Reduction and Internal Fixation (ORIF) and Total Elbow Arthroplasty (TEA) as primary procedures, although we have been unable to find any direct comparisons of outcome. This study reports the results of ORIF in 12 elderly patients with distal humeral fractures and compares the outcome with 12 matched patients who had undergone TEA. All procedures were performed by two experienced Consultant Surgeons. The Coonrad-Morrey TEA was used in all cases of TEA and a double-plating technique was used in all ORIFs. Both groups of patients were similar with respect to fracture configuration, age, sex, co-morbidity and hand dominance. The mean follow-up in both groups of patients was over 30 months. At final review, patients who had had a TEA had a mean Mayo score of 91 and a range of flexion/extension of 90 degrees. There was 1 superficial wound infection that resolved with antibiotics, 1 temporary radial nerve palsy, and 1 case of heterotrophic ossification The ORIF group had a mean Mayo score of 89 (p>
0.05) and a range of flexion/extension of 112 degrees (P=0.03). There was 1 case of heterotrophic ossification, 2 cases of ulnar nerve compression that needed decompression and 1 superficial wound infection that resolved with antibiotics. All the fractures united.
MRI arthography (MRA) is commonly used in the investigation of shoulder instability. However many surgeons are now using CT arthography (CTA) as their primary radiological investigative modality. They argue that CTA is cheaper, and give satisfactory soft tissue images in the “soft tissue window” mode. They believe that CTA give superior images when looking at bone loss and bony defects, and as such is more useful in deciding whether a patient requires an open procedure or not. In this study we aimed to compare the results of MRA and CTA in the investigation of shoulder instability. We reviewed the operative and arthographic findings in all patients who had surgery for shoulder instability in our unit over a 4 year period. We compared the results of the arthograms with the definitive findings found at the time of surgery. All arthograms were performed by standard techniques and were reported by musculoskeletal radiology consultants. All surgery was performed by experienced consultant shoulder surgeons. In total 48 CTAs and 50 MRAs were performed. We found that there was no significant difference between the two wrt sensitivity (p=0.1) and specificity (p=0.4) when looking at labral pathology. However CTA was more sensitive at picking up bony lesions (p<
0.05). This study supports the view that CT arthography is the superior radiological modality in identifying pathology when investigating patients with shoulder instability. It is cheaper and better tolerated by patients than MRA and gives useful information on whether a patient needs an open or arthroscopic stabilisation procedure.
Total elbow arthroplasty (TEA), as a primary procedure and open reduction and internal fixation (ORIF) have been used to treat complex intra-articular distal humeral fractures in elderly patients. The failure rate after ORIF is high and TEA has often been used as a salvage procedure. Although satisfactory results have been reported after TEA as a primary procedure, there are no publications reporting the results of TEA after failed internal fixation (FIF). In this study we compared the results of patients that had TEA after FIF with those that had had primary arthroplasty (PA). We reviewed the results of 9 consecutive patients who had FIF with 12 patients who had PA. All the operations were performed by one surgeon using the same technique and same prosthesis. Both groups of patients were similar with respect to ages, sex, co-morbidity and hand dominance. The mean follow-up for both groups of patients was 5 years. At final review, patients who had had FIF had a mean Mayo score of 68 and a range of flexion/extension of 90 degrees, there was 1 infection and 1 case of loosening. The PA group had a mean Mayo score of 88 and a range of flexion/extension of 96 degrees, there were no cases of infection or loosening. This study shows the results of TEA are satisfactory either as a PA or after FIF, however the results after PA are significantly better than after FIF.
