The results of excision of the head of the radius in forty-four elbows affected by rheumatoid arthritis are presented. Relief of pain was obtained in 90 per cent and an increase in the range of flexion and extension was seen in 70 per cent. Involvement of the humero-ulnar joint seen radiologically is no contra-indication to the operation; simple excision of the radial head often gives gratifying results; In our experience the relief of pain and increased range of movement have greatly reduced the need for total replacement arthroplasty

1. Nineteen patients with classical rheumatoid arthritis complicated by severe subluxation of the cervical spine are reported. 2. Thirteen patients had atlanto-axial subluxation. This was the only level ofinvolvement in ten. 3. The next most frequent level to be involved was C.4-5. This occurred in five patients. 4. Eleven patients required surgery for symptoms or signs of spinal cord compression or vertebral artery insufficiency. 5. Operations included six posterior fusions, three anterior fusions and two laminectomies. 6. The differential diagnosis, the radiological findings, the indications for surgery and the results of treatment are discussed

The short-term assessment of 14 arthroscopic synovectomies of the elbow in 11 patients with rheumatoid arthritis showed that 93% achieved a short-term rating of excellent or good on the Mayo Elbow Performance Score. At the most recent assessment at an average of 42 months, however, only 57% maintained excellent or good results; four had required total elbow replacement. Although rehabilitation is facilitated by an arthroscopic procedure the results deteriorate more rapidly than after open synovectomy. This may be due to the limitations of the arthroscopic technique and is consistent with experience of the similar procedure in the knee. Recognition of the short-term gain and the potential for serious nerve injury should be considered when offering arthroscopic synovectomy

1. Opinion is divided as to the value of synovectomy of the knee in juvenile rheumatoid arthritis. 2. Between 1964 and 1970 thirty synovectomies of the knee were performed in twenty-seven children, who have now been kept under review for one to eight years. Three have required a second operation. 3. The operative findings at various stages are presented and discussed, with special reference to the effect on growth of the limb. 4. Synovectomy is a useful procedure which should be reserved for cases where effusion persists despite nine months of conservative treatment and performed before signs of bone erosion appear

1. Of fifty consecutive double hemiarthroplasties of the knee for rheumatoid arthritis using Maclntosh prostheses, forty-six were available for detailed assessment in thirty-six patients after one to six years. 2. Two early deaths were related to the operation but two late deaths were not. Three knees required revision, one of them twice. 3. The late results were 87 per cent good and 13 per cent fair. No patients followed up were the same as previously or worse. Every patient stated that he would have the operation performed again. 4. In our experience this operation in carefully selected patients produces satisfactory results. It is essential that great care is given to the operative technique

1. Bony spurs resulting from erosion of the scaphoid bone and trapezium in rheumatoid arthritis can pierce the floor of the carpal tunnel and cause attrition rupture of flexor tendons–most often the flexor pollicis longus tendon. 2. It is difficult to show these spurs on conventional radiographs, but using a special tomographic technique we have been able to explore the floor of the carpal tunnel in three planes. Using this technique we have been able to guard the flexor pollicis longus against attrition rupture by early excision of a spur from the scaphoid bone. 3. Our findings support the recommendation of free division of the flexor retinaculum in rheumatoid arthritis. When doing this the surgeon should always look for a bony spur piercing the floor of the carpal tunnel

We have performed a clinical and radiological analysis of 105 shoulder arthroplasties in patients with rheumatoid arthritis. The clinical results showed improvements in the Constant-Murley and Association of Shoulder and Elbow Surgeons score of 21 and 35, respectively. Both were statistically significant (p < 0.001). This improvement was maintained over a period of 8.8 years. There was no statistically significant difference in the scores after hemiarthroplasty and those after total arthroplasty. The presence of an intact rotator cuff was associated with improved function in both groups. In spite of the use of an uncemented humeral stem, no implant was radiologically loose or at risk. There was lucency in a single zone in 14 implants. One glenoid component was at risk and 16 had lucency in a single zone. There was, however, a significant difference in the amount of lucency which was associated with pegged and keeled glenoid components (p = 0.005). In the group with hemiarthroplasty, two or more years after surgery there was superior migration of the humeral component by more than 5 mm in 18 shoulders (28%) and medial migration by more than 2 mm in eight (16%). Both superior and medial migration had an effect on the outcome. Revision was undertaken in four patients for persistent pain relating to medial migration. With revision taken as the endpoint for survival after eight years, 92% were found to be still in situ

We compared the outcome of peri-operative humeral condylar fractures in patients undergoing a Coonrad-Morrey semiconstrained total elbow replacement with that of patients with rheumatoid arthritis undergoing the same procedure without fractures. In a consecutive series of 40 elbows in 33 patients, 13 elbows had a fracture in either condyle peri-operatively, and 27 elbows were intact. The fractured condyle was either fixed internally or excised. We found no statistical difference in the patients’ background, such as age, length of follow-up, immobilisation period, Larsen’s radiological grade, or Steinbrocker’s stage and functional class. There was also no statistical difference between the groups in relation to the Mayo Elbow Performance Score, muscle strength, range of movement, or radiolucency around the implants at a mean of 4.8 years (1.1 to 8.0) follow-up. We conclude that fractured condyles can be successfully treated with either internal fixation or excision, and cause no harmful effect

1. The results of excision of the distal end of the ulna in eighty-six wrists of seventy patients suffering from rheumatoid arthritis are presented. 2. There was relief of pain in 93 per cent and restoration of full rotation in 87 per cent. 3. Further destructive changes of the radio-carpal joint were seen in 85 per cent, but these did not affect the good clinical results

The effects of synovectomy and excision of the radial head in 40 elbows affected by rheumatoid arthritis have been assessed. In contrast with many reports indicating minimal side-effects of this procedure, a common pattern of deterioration from what was often a satisfactory initial result has been demonstrated. A biomechanical theory of one of the factors responsible for failure has been put forward and the importance of conserving or replacing the radial head emphasised

1. Four patients with tetraplegia from rheumatoid subluxation occurring in the lower cervical spine are described and the common features are noted. 2. Compression appeared to be responsible for the cord damage, although it was not necessarily directly related to vertebral subluxation. The lesions causing the compression were varied. 3. Forcible attempts to reduce vertebral subluxation may be harmful. Two patients were improved by posterior decompression. 4. A suggested programme for the treatment of such patients is outlined

Bilateral posterior interosseous nerve palsy in a rheumatoid patient is described. Six previous case reports and our experience indicate that steroid injection into the elbow may not produce lasting recovery and may lead to unacceptable delay before surgical decompression. An anterolateral approach for division of the arcade of Frohse is effective in cases with diffuse synovitis; where there is a local cystic swelling a posterolateral approach provides better access. Good recovery of nerve function can be expected after early operation

Simple decompression of the extensor tendons at the wrist was carried out on fifty-four wrists in a total of forty-one patients with rheumatoid disease. This procedure was combined with excision of the ulnar head in forty-five wrists. Complete resolution of the synovitis occurred in 81.5 per cent of the wrists. In two patients the tendons ruptured soon after operation and in both cases this was due to prolapse of the ulnar stump after an associated Darrach procedure. The clinical results of decompression compare favourably with those of the widely accepted operation of dorsal tenosynovectomy

1. One hundred and twenty-six metacarpo-phalangeal joints affected by rheumatoid arthritis were studied macroscopically at either synovectomy or arthroplasty. 2. The sites and extent of the initial erosion corresponded with the sites and size of the synovial pouches. 3. The areas of cartilage degeneration were related to the degree of flexion, ulnar deviation and subluxation of the proximal phalanx on the metacarpal head. 4. The routine radiographic findings were not a true reflection of all the pathological changes within the joint. 5. It is suggested that by encouraging joint movement and preventing deformity the degree of cartilage degeneration may be diminished

We reviewed 50 capitellocondylar elbow replacements performed by the lateral approach in 42 rheumatoid patients, at a median follow-up of three years. There were two major and 17 minor complications; 18 were early and one was late. Eight elbows required reoperation: soft-tissue surgery was performed in seven and prosthesis removal in one because of a deep infection. There were few problems of instability, but one patient sustained a traumatic dislocation which was stabilised after ligament reconstruction. Wound healing was delayed in two of five elbows which had been immobilised postoperatively for only five days, but healing was rapid in 45 elbows immobilised for 12 days. There was transient ulnar-nerve palsy postoperatively in 11 patients, with permanent palsy in three. All elbows were painfree or only slightly painful at follow-up; 49 were stable and 43 had a range of motion sufficient for activities of daily living. Radiological loosening of the humeral component was suspected in one asymptomatic elbow. The lateral approach is recommended for use with the capitellocondylar type of prosthesis in rheumatoid elbows with reasonably well-preserved bone stock

We reviewed 61 elbow synovectomies in 50 patients with rheumatoid arthritis, with follow-up varying from 4 to 10 years (mean 6.5 years). The results were graded as satisfactory in 70%, with no significant difference in the results between joints which were radiologically good before operation and those which had been destroyed. Longer term results were analysed of 27 elbow synovectomies in 22 patients followed up for over six years. The results were satisfactory in 67% of the patients in both 1981 and in 1987, with no deterioration over this period

Twenty-six patients with rheumatoid arthritis who had undergone bilateral replacement of the hip and knee were reviewed at a mean follow-up time of 51.6 months. A further operation was necessary in five patients due to complications of replacement of the knee, and seven patients still had significant pain in at least one replaced joint. There were no cases of infection due to operation. Seventeen of the patients still used walking aids, but one-third of these did so because of pain in joints that had not been replaced. Patients preferred painless total replacement of the hip to that of the knee

The results of excision of the distal ulna in 34 wrists of 25 patients with chronic rheumatoid arthritis of the distal radio-ulnar joint were reviewed. Rest pain had been cured or relieved in 77%, pain on pronation-supination in 86%, and limitation of pronation-supination in 90%, while 88% of the patients graded the result as excellent or fair. Despite this marked relief of symptoms, function of the upper limb was improved in only 25% of patients and remained unchanged in 60%. Ulnar subluxation of the carpus had occurred in 24% but seemed to be related to the destructive disease process rather than to the operation itself. The length of ulna resected was not related to the outcome of the operation

1. The treatment is described of a consecutive series of fourteen patients suffering from rheumatoid arthritis causing a slip of the cervical vertebrae, mainly at the C.1-2 level, and a cord lesion. 2. The importance of a change of symptoms and signs in these patients, especially the occurrence of the so-called "alarm signs", is stressed. 3. In twelve patients the combination of this kind of cervical instability with a cord lesion was treated by fusion, most frequently of occiput to C.2 and 3. 4. In the eleven patients who survived the operation the results with a follow-up period of one to eight years are considered highly gratifying. 5. Technical details and various problems associated with treatment are discussed

Six highly unstable elbows with severe bone loss due to rheumatoid arthritis were replaced by a non-constrained, unlinked prosthesis. Bone defects were filled with autogenous bone grafts. The mean follow-up was 4.5 years (2 to 8). The clinical results were excellent in four elbows and good in two, with good varus-valgus stability in all. Radiological follow-up showed no appreciable signs of loosening, and the bone grafts had retained most of their original size, with minimal resorption. There were no major complications such as dislocation, skin necrosis, infection or ulnar neuropathy. The study has shown that the so-called mutilans elbow can be successfully replaced using a properly selected type of non-constrained, unlinked prosthesis with bone grafting of the major defects
