1 . A classification of Madelung's deformity on an etiological basis is suggested. 2. Seven patients with "idiopathic" Madelung's deformity and one occurring in association with Turner's syndrome are discussed. 3. Cytogenetic studies of five patients are recorded and their significance discussed. 4. Arthrodesis of the radio-carpal joint by the "wedge" technique is preferred for those patients whose symptoms warrant treatment

Between 1999 and 2005, 23 failed total ankle replacements were converted to arthrodeses. Three surgical techniques were used: tibiotalar arthrodesis with screw fixation, tibiotalocalcaneal arthrodesis with screw fixation, and tibiotalocalcaneal arthrodesis with an intramedullary nail. As experience was gained, the benefits and problems became apparent. Successful bony union was seen in 17 of the 23 ankles. The complication rate was higher in ankles where the loosening had caused extensive destruction of the body of the talus, usually in rheumatoid arthritis. In this situation we recommend tibiotalocalcaneal arthrodesis with an intramedullary nail. This technique can also be used when there is severe arthritic change in the subtalar joint. Arthrodesis of the tibiotalar joint alone using compression screws was generally possible in osteoarthritis because the destruction of the body of the talus was less extensive. Tibiotalocalcaneal arthrodesis fusion with compression screws has not been successful in our experience

Aims

A multicentre, randomized, clinician-led, pragmatic, parallel-group orthopaedic trial of two surgical procedures was set up to obtain high-quality evidence of effectiveness. However, the trial faced recruitment challenges and struggled to maintain recruitment rates over 30%, although this is not unusual for surgical trials. We conducted a qualitative study with the aim of gathering information about recruitment practices to identify barriers to patient consent and participation to an orthopaedic trial.

Arthrodesis after the removal of a knee prosthesis is often hampered by the small area of contact of the bony surfaces and by pre-existing infection. Conventional systems of external fixation and compression frequently fail to achieve stability but the addition of the Wagner leg-lengthening apparatus applied anteriorly and adjusted to give compression ensures rigid external fixation. Four knees in four patients were treated using this technique; the treatment followed the removal of infected prostheses in three knees and painful fibrous ankylosis after the removal of the prosthesis in the other. All obtained a sound arthrodesis

1. Thirty-one cases of tuberculosis of the elbow have been reviewed and the general characters of the disease described. 2. The condition is classified into four types distinguishable radiologically. 3. Treatment is predominantly conservative. Operation is sometimes indicated for extra-articular lesions. Arthrodesis is advisable in selected cases but it is not essential for healing. 4. Of twenty patients observed for five years or more, seventeen returned to work, seven required permanent splintage and five had residual pain or sinuses. 5. It is suggested that the best position for fixation of the elbow is 30 degrees below the right angle

We reviewed 12 patients with congenital hallux varus who had had operations on 20 feet to enable them to wear normal shoes and to improve the appearance. After an average follow-up of 12.7 years the results of soft tissue procedures were satisfactory in 12 of 17 feet. Arthrodesis of the first metatarsophalangeal joint, performed primarily in one foot and secondarily in two others was also satisfactory, but metatarsal osteotomy in two feet gave unsatisfactory results leading to local amputation. The unsatisfactory results were generally due to the appearance of shortness of the first metatarsal and rarely because of symptoms or recurrent deformity

We reviewed 15 patients with an arthrodesis of the elbow using an AO compression-plate technique, after an average follow-up of 24 months. The most common indication was an open, infected high-energy injury with associated bone loss. Arthrodesis was successful in all but one patient in whom severe deep infection necessitated amputation. Eight patients were treated with the metal partly exposed in an infected wound. After removal of the metal, all wounds healed secondarily and none had clinical or radiographic signs of sepsis at latest review. Compression-plate arthrodesis of the elbow is a generally applicable method that can be used even in cases of severe bone loss. There appears to be greater certainty of union than with other techniques, and no increased risk of subsequent fracture

In order to define the predisposing factors and outcome of infected arthroplasty of the knee, a retrospective analysis of a consecutive series of 471 knee arthroplasties was performed. There were 23 cases of superficial wound infection and 25 of deep infection. Superficial wound infection alone resulted in a painfree gait, with little limitation of movement. Rheumatoid arthritis, the use of constrained prostheses and the presence of a superficial wound infection, all predisposed to deep infection. Deep infection was eradicated by long-term antibiotics in only two patients in whom skin cover was successfully provided by a gastrocnemius musculocutaneous flap. Excision of a sinus track, wound debridement and exchange arthroplasty were universally unsuccessful. Arthrodesis, however, in 11 out of 12 cases, provided the painfree gait these patients desire

1. Thirty-eight patients with sixty-two forefoot arthroplasties have been followed up from two to thirteen years after the operation. Eleven were free of pain, thirty-eight had some pain but were improved, and the rest were worse. 2. Patients over the age of fifty or with rheumatoid arthritis did best. 3. Kirschner wire fixation of the great toe often caused late painful stiffness of the metatarsophalangeal joint. 4. Previous interphalangeal fusion of a lesser toe was often the cause of metatarso-phalangeal dislocation of that toe and callous formation. 5. Arthrodesis of the metatarso-phalangeal joint of the great toe gave a high proportion of painless feet, apparently because it prevented both painful stiffness at that joint and dislocation of the same joint of the lesser toes

We report a retrospective study of 54 acetabular fractures treated by open reduction and internal fixation, with an average follow-up of 9.6 years (3 to 17). Reduction leaving displacement of less than or equal to 2 mm was achieved in 36 hips (67%); good or excellent functional results were obtained in 33 patients (61%). Early complications requiring re-operation included postoperative loss of reduction in one case and an intra-articular screw in another. Arthrodesis or total hip arthroplasty had been performed in 10 patients (19%) who had late symptomatic degenerative changes. Failure to obtain accurate reduction was the most important factor leading to a poor result, but heterotopic calcification caused poor results in seven patients, five of whom had had an anatomical reduction

We have reviewed 30 patients at a mean of 36 months after free vascularised fibular transfer to reconstruct massive skeletal defects after resection of primary bone tumours. There were 23 malignant and 7 benign neoplasms, half in the lower limb and half in the upper. Arthrodesis was performed in 15 and intercalary bone replacement in 15. The mean fibular graft length was 189 mm. Union was achieved in 27 (90%) at an average of 7.6 months, and the 3-year survival was 89%. There was a high complication rate (50%), but most resolved without greatly influencing the final outcome. There was local recurrence in two (6.7%), but 16 of the 24 assessed patients (67%) had satisfactory functional results. This is a reasonably effective means of reconstruction for limb salvage after resection of tumours

Osteoarthritis of the wrist is a complication of a number of common traumatic conditions. Arthrodesis of the radiocarpal joint, proximal row carpectomy and excision of the scaphoid, combined with midcarpal arthrodesis, have all been reported as surgical options. There have been no randomised studies comparing these procedures, and the feasibility of conducting this type of trial is limited. We used decision analysis to compare the three surgical techniques. The variables for the model used were based principally on data from the literature. Extensive sensitivity analyses were carried out to test the impact of the values given to these variables on the outcome of the model. The model indicated that the preferred treatment is proximal row carpectomy. Decision analysis allows a comparison between alternative treatments, when evidence from a randomised trial is lacking or unobtainable. The decision-analysis model may also provide insight into aspects of a problem which would be difficult, or impossible, to evaluate by a cohort study

Eighty-three Waildius arthroplasties, performed by one surgeon as a salvage operation on the knee joint between 1966 and 1972, were independently reviewed. The fifty-seven living patients with sixty-seven arthroplasties were interviewed and examined and the clinical records of the deceased patients were inspected. Sixty-seven arthroplasties (81 per cent) were successful and sixteen failed (19 per cent). Acrylic cement was used to secure the prosthesis on eight occasions only. There were two primary infections (24 per cent) and two delayed (24 per cent). Major loosening occurred in three arthroplasties (36 per cent). Minor loosening was compatible with a good result. Arthrodesis was successful on the two occasions on which it became necessary to remove the implant. There were no disasters. On the basis of these results it is considered that the Walidius arthroplasty can justifiably be offered as an alternative to primary arthrodesis of the knee

Simultaneous paralysis of the ulnar, median and radial nerves is seen in about 1% of hands with nerve involvement in Hansen's disease. Forty such cases were treated between 1955 and 1976; 35 of these have been followed up. In two hands there was a high radial, median and ulnar palsy and these left no scope for reconstruction. The other 33 cases which underwent two-stage reconstructive surgery are presented here. The first stage consisted of restoring active extension of the wrist, fingers and thumb: for this purpose the ideal muscles for transfer are pronator teres, flexor carpi radialis and palmaris longus respectively, and muscle power exceeding Grade 3 (on the MRC classification) was achieved in 89%, 96%, and 100% of these individual transfers. Arthrodesis of the wrist is not recommended when suitable muscles are available for transfer. The second stage of reconstruction attempts to restore intrinsic function of the fingers and opposition of the thumb; the sublimis is ideal for both purposes and satisfactory restoration of function was achieved in 89% and 85% of cases respectively. Ten of the 18 hands in which all five tendons were transferred had good or excellent results

Tibiotalar fusion is considered to be the standard treatment for end-stage post-traumatic arthritis of the ankle. We report a retrospective, objective long-term study of the quality of life of 17 patients with 18 arthrodeses of the ankle, over a period of more than 20 years. We looked particularly for correlation between clinical and radiological signs of osteoarthritis in adjoining joints. At serial physical examinations, clinical grades were awarded according to the Olerud Molander Ankle (OMA) score. Any degree of degenerative change in the adjoining joints was recorded on standing radiographs. Patients filled out a SF-36 Health Survey form. Subjectively, 50% of patients were not handicapped in the performance of daily activities and 44% were in the same job as at the time of injury. At follow-up the mean OMA score was 59.4 points, the visual analogue scale was 1.99 and the radiological score was 2.7. The SF-36 for physical function, emotional disturbance and bodily pain revealed significant deficits. There was a significant correlation between the OMA and the radiological score (p = 0.05), and between the clinical and the SF-36 score (p = 0.01), but no significant correlation between the radiological score and the SF-36 score. Arthrodesis of the ankle leads to deficits in the functional outcome, to limitations in the activities of daily living and to radiological changes in the adjoining joints. The clinical outcome score correlates closely with the SF-36 score

1. In congenital absence of the fibula, the fibrous strip that replaces the bone, abnormal insertions of fibular muscles, and disturbances in the formation and growth of the tarsal bones all go to cause the valgus deformity of the foot and the complete or partial dislocation of the talo-tibial joint. 2. Conservative treatment is justified only for children less than a year old and then only as preparation for operation. 3. Between the second and seventh year of life operations upon the soft tissues are indicated, to eliminate the contractures occurring on the posterior and lateral sides, to restore the proper position of the foot in line with the axis of the tibia, and to restore the normal shape of the foot and muscular equilibrium. At the same time favourable conditions are created for operative reconstruction of the lateral malleolus. 4. Arthrodesis of the talo-tibial joint or reconstruction of the lateral malleolus by a bone graft with the aim of stabilising the foot in the axis of tibia is not advisable in the growing limb. 5. The results obtained in three cases described support the conclusion that the bifurcation operation recommended by Gruca produces a new lateral malleolus with an epiphysis that grows at the same rate as the remainder of the lower epiphysis of the tibia, does not affect the rate of growth of the tibial epiphysis, prevents the recurrence of the deformity, and preserves the mobility of the talo-tibial joint. 6. In early cases this reconstructive operation may be done at the same time as soft-tissue deformities are corrected and subluxation reduced. 7. It is probable that the bifurcation operation should be done on children aged between two and seven years in order to give the limb the best chance to develop normally

Aims

The aim of this retrospective study was to compare the correction achieved using a convex pedicle screw technique and a low implant density achieved using periapical concave-sided screws and a high implant density. We hypothesized that there would be no difference in outcome between the two techniques.

1. The results of fifty-three operations in forty adults with a persistent congenital dislocation of the hip have been reviewed. 2. Arthrodesis as a primary operation was successful in five of six patients, giving a pain-free hip and good function. After an arthroplasty or an osteotomy that had failed to relieve symptoms it was successful in only one patient. 3. Cup arthroplasty on one hip relieved pain in five of nine patients, giving an increase in functional activity, although the range of hip movement was often disappointing. Bilateral cup arthroplasty, performed in four patients, gave partial relief in three, but did not permit an increase in activity. 4. High osteotomy of the femur was undertaken in eleven patients with a unilateral dislocation; pain was rarely relieved, and a stiff hip resulted in seven. 5. Low osteotomy in nine patients gave some relief from pain with a good range of hip movement. 6. In unilateral dislocation arthrodesis appeared to be the operation of choice, although cup arthroplasty was capable of giving a good functional result. 7. In bilateral dislocation, when only one hip was painful, the results of both these operations were on the whole good. When both hips were painful the operations that had been performed seldom gave clinical improvement. 8. High osteotomy of the femur appeared to have little place in the treatment of the painful dislocated hip. Low osteotomy, either of the Schanz or Batchelor type, appeared to be of value mainly as a salvage procedure when other measures had failed to give relief

Aims

Base of thumb osteoarthritis (BTOA) is a common age-related disease which has a significant negative impact upon quality of life. Our aim was to assess current UK practice in secondary care with regard to the nature of non-surgical treatments, the surgical procedures most commonly performed, and factors influencing the surgical decision-making process.
