Aims

In cases of severe periprosthetic joint infection (PJI) of the knee, salvage procedures such as knee arthrodesis (KA) or above-knee amputation (AKA) must be considered. As both treatments result in limitations in quality of life (QoL), we aimed to compare outcomes and factors influencing complication rates, mortality, and mobility.

We report our experience with glenohumeral arthrodesis as a salvage procedure for epilepsy-related recurrent shoulder instability. A total of six patients with epilepsy underwent shoulder fusion for recurrent instability and were followed up for a mean of 39 months (12 to 79). The mean age at the time of surgery was 31 years (22 to 38). Arthrodesis was performed after a mean of four previous stabilisation attempts (0 to 11) in all but one patient in whom the procedure was used as a primary treatment. All patients achieved bony union, with a mean time to fusion of 2.8 months (2 to 7). There were no cases of re-dislocation. One revision was undertaken for loosening of the metalwork, and then healed satisfactorily. An increase was noted in the mean subjective shoulder value, which improved from 37 (5 to 50) pre-operatively to 42 (20 to 70) post-operatively although it decreased in two patients. The mean Oxford shoulder instability score improved from 13 pre-operatively (7 to 21) to 24 post-operatively (13 to 36). In our series, glenohumeral arthrodesis eliminated recurrent instability and improved functional outcome. Fusion surgery should therefore be considered in this patient population. However, since the majority of patients are young and active, they should be comprehensively counselled pre-operatively given the functional deficit that results from the procedure.

Arthrodesis of the wrist is a standard operation which is indicated for severe rheumatoid arthritis in which destruction is too advanced for more conservative procedures, or after failure of previous surgery. We have developed an L-shaped plate designed for this purpose. It provides rigid internal fixation with the wrist in the neutral position and utilises bone grafts obtained from the distal ulna and the carpal bones. We have carried out 29 successful fusions between 1992 and 1995. In all 29 patients synovectomy and resection of the head of the ulna were performed; 11 also had reconstruction of ruptured extensor tendons. All the patients obtained bony union, pain relief and improved function

1. Arthrodesis of the hip is satisfactory provided a good range of knee flexion is preserved. 2. The hip is best arthrodesed in its deformed position, and the deformity corrected by a high femoral osteotomy. Knee range can readily be retained by treating the patient on traction for the first six weeks instead of using plaster. 3. Thirty-three arthrodeses were attempted without osteotomy. Only thirteen were satisfactory. Even our best method without osteotomy gave sound fusion in only seven out of ten cases. 4. In a series of twenty-three unselected cases in which osteotomy was performed in addition to other methods, fusion occurred in twenty-two

Arthrodesis of the knee is sometimes needed for failed total knee replacement, but fusion can be difficult to obtain. We describe a method of arthrodesis that uses the simple, inexpensive, Portsmouth external fixator. Bony union was obtained in all six patients treated with this technique. These results are compared with those obtained by other methods of arthrodesis

Forty-one arthrodeses of the shoulder in thirty-nine patients suffering from rheumatoid arthritis (thirty women, nine men) have been reviewed. Using internal fixation and external splints the position of the shoulder was maintained in 55 degrees of abduction, 25 degrees of horizontal flexion and enough internal rotation to allow the patient to reach the mouth. The mean period of immobilisation in a thoracobrachial splint was nine weeks, and 90 per cent of the shoulders had solid bony fusion at review. After arthrodesis the total range of scapulothoracic movement improved by about 60 per cent, giving results rated as excellent in fifteen cases (36 per cent), as good in thirteen (32 per cent) and as fair in thirteen (32 per cent). Arthrodesis can be recommended as an easy, cheap and reliable method of treating a shoulder which has been severely destroyed by rheumatoid arthritis

Aims

Plate and screw fixation has been the standard treatment for painful conditions of the wrist in non-rheumatoid patients in recent decades. We investigated the complications, re-operations, and final outcome in a consecutive series of patients who underwent wrist arthrodesis for non-inflammatory arthritis.

Aims

Improvements in functional results and long-term survival are variable following conversion of hip fusion to total hip arthroplasty (THA) and complications are high. The aim of the study was to analyze the clinical and functional results in patients who underwent conversion of hip fusion to THA using a consistent technique and uncemented implants.

Aims

Children treated for osteosarcoma around the knee often have a substantial leg-length discrepancy at skeletal maturity. The aim of this study was to investigate the results of staged skeletal reconstruction after a leg lengthening procedure using an external fixator in these patients.

Aims

Postoperative rehabilitation regimens following ankle arthrodesis vary considerably. A systematic review was conducted to determine the evidence for weightbearing recommendations following ankle arthrodesis, and to compare outcomes between different regimens.

We retrospectively evaluated eight patients who underwent arthrodesis of the knee using cannulated screws. There were six women and two men, with a mean age of 53 years. The indications for arthrodesis were failed total knee arthroplasty, septic arthritis, tuberculosis, and recurrent persistent infection. Solid union was achieved in all patients at a mean of 6.1 months. One patient required autogenous bone graft for delayed union. One suffered skin necrosis which was treated with skin grafting. The mean limb-length discrepancy was 3.1 cm. On a visual analogue scale, the mean pain score improved from 7.9 to 3.3. According to the Knee Injury and Osteoarthritis Outcome score quality of life items, the mean score improved from 38.3 pre-operatively to 76.6 at follow-up. Cannulated screws provide a high rate of union in arthrodesis of the knee with minimal complications, patient convenience, and a simple surgical technique.

Aims

This retrospective cohort study compared the results of vascularised and non-vascularised anterior sliding tibial grafts for the treatment of osteoarthritis (OA)of the ankle secondary to osteonecrosis of the talus.

Objectives

Pulsed electromagnetic field (PEMF) stimulation was evaluated after anterior cervical discectomy and fusion (ACDF) procedures in a randomized, controlled clinical study performed for United States Food and Drug Administration (FDA) approval. PEMF significantly increased fusion rates at six months, but 12-month fusion outcomes for subjects at elevated risk for pseudoarthrosis were not thoroughly reported. The objective of the current study was to evaluate the effect of PEMF treatment on subjects at increased risk for pseudoarthrosis after ACDF procedures.

We present a series of 16 patients treated between 1993 and 2006 who had a failed total ankle replacement converted to an arthrodesis using bone grafting with internal fixation. We used tricortical autograft from the iliac crest to preserve the height of the ankle, the malleoli and the subtalar joint. A successful arthrodesis was achieved at a mean of three months (1.5 to 4.5) in all patients except one, with rheumatoid arthritis and severe bone loss, who developed a nonunion and required further fixation with an intramedullary nail at one year after surgery, before obtaining satisfactory fusion. The post-operative American Orthopaedic Foot and Ankle Society score improved to a mean of 70 (41 to 87) with good patient satisfaction. From this series and an extensive review of the literature we have found that rates of fusion after failed total ankle replacement in patients with degenerative arthritis are high. We recommend our method of arthrodesis in this group of patients. A higher rate of nonunion is associated with rheumatoid arthritis which should be treated differently.

In a prospective randomised study 31 patients were allocated to either arthrodesis or Mayo resection of the first metatarsophalangeal joint as part of a total reconstruction of the rheumatoid forefoot. Of these, 29 were re-examined after a mean of 72 months (57 to 80), the Foot Function Index was scored and any deformity measured. Load distribution was analysed using a Fscan mat in 14 cases, and time and distance were measured in 12 of these patients using a 3D Motion system. We found excellent patient satisfaction and a significant, lasting reduction of the Foot Function Index, with no statistically significant differences between the groups. There were no significant differences in recurrence of the deformity, the need for special shoes, gait velocity, step length, plantar moment, mean pressure or the position of the centre of force under the forefoot. The cadence was higher and the stance phase shorter in the fusion group.

These results suggest that a Mayo resection may be an equally good option for managing the first metatarsophalangeal joint in reconstruction of the rheumatoid forefoot.

Aims

Total wrist arthrodesis (TWA) produces a spectrum of outcomes. We investigated this by reviewing 77 consecutive TWA performed for inflammatory and post-traumatic arthropathies, wrist instability and as a salvage procedure.

Aims

Few reports compare the contribution of the talonavicular articulation to overall range of movement in the sagittal plane after total ankle arthroplasty (TAA) and tibiotalar arthrodesis. The purpose of this study was to assess changes in ROM and functional outcomes following tibiotalar arthrodesis and TAA.

A consecutive series of 23 patients (25 ankles) with osteoarthritis of the ankle and severe varus or valgus deformity were treated by open arthrodesis using compression screws. Primary union was achieved in 24 ankles one required further surgery to obtain a solid fusion. The high level of satisfaction in this group of patients reinforces the view that open arthrodesis, as opposed to ankle replacement or arthroscopic arthrodesis, continues to be the treatment of choice when there is severe varus or valgus deformity associated with the arthritis.

1. This report defines the indications, and describes in detail a technique for atlanto-axial arthrodesis. Open reduction, with wire fixation and bone grafting, achieves the objective of immediate stabilisation of an unstable C. 1-2 articulation.

2. The method is illustrated by fifteen consecutive patients who had atlanto-axial arthrodesis. fourteen of whom had excellent results.

3. When the indications are correct, atlanto-axial arthrodesis by the method described is a safe and effective procedure having an excellent success rate.

1. A method of arthrodesis of the ankle is described which combines the compression principle of Charnley with the medial approach to the joint described by Pridie.

2. Fusion occurred promptly in seventeen out of nineteen cases. In one case fusion was delayed, and in one case there was failure of fusion.

1. Sixty-nine patients with degenerative disease of the hip joint were treated by intra-articular arthrodesis using secure internal fixation. External fixation with plaster was not used and the patients were mobilised on crutches after a mean interval of 3·2 weeks. Radiologically evident bony union occurred in 87 per cent of cases. Among the nine patients (13 per cent) who failed to show union only three complained of persistence of severe symptoms.

2. The only significant complication was fracture of the upper femoral shaft in three cases (4·3 per cent). However, this has not occurred since a small plate was used in addition to the nail.

3. The disadvantages of the routine use of plaster fixation are discussed and are contrasted with the advantages of early mobilisation without plaster.

4. Whereas this series does not show a rate of fusion as good as that in the best reported series, it supports the view that arthrodesis of the hip offers the most certain, reliable and efficient means of treatment for severe unilateral degenerative disease of that joint.

It will be seen that the proportion of successful fusions in this series of ninety-five patients treated by ischio-femoral arthrodesis of the hip was over 80 per cent. Similar percentages of successful fusion have been reported by Knight (1945), Freiberg (1946), Langston (1947), and Nisbet, who was resident surgical officer at the Robert Jones and Agnes Hunt Orthopaedic Hospital, and informed me in a personal communication that he had carried out twenty-six operations with an approximate fusion rate of 80 per cent. He stated: "It is the only operation which gives a reasonable chance of a successful arthrodesis in children. Up till now at Oswestry the chances of a fusion by the other methods in children have proved so disappointing that the operation had been abandoned. Dame Agnes Hunt, with her vast experience of the condition, was always very annoyed when she found a surgeon trying to fuse a child's hip. All this has been changed."

A combined anterior and posterior surgical approach is generally recommended in the treatment of severe congenital kyphosis, despite the fact that the anterior vascular supply of the spine and viscera are at risk during exposure. The aim of this study was to determine whether the surgical treatment of severe congenital thoracolumbar kyphosis through a single posterior approach is feasible, safe and effective.

We reviewed the records of ten patients with a mean age of 11.1 years (5.4 to 14.1) who underwent surgery either by pedicle subtraction osteotomy or by vertebral column resection with instrumented fusion through a single posterior approach.

The mean kyphotic deformity improved from 59.9° (45° to 110°) pre-operatively to 17.5° (3° to 40°) at a mean follow-up of 47.0 months (29 to 85). Spinal cord monitoring was used in all patients and there were no complications during surgery. These promising results indicate the possible advantages of the described technique over the established procedures. We believe that surgery should be performed in case of documented progression and before structural secondary curves develop. Our current strategy after documented progression is to recommend surgery at the age of five years and when 90% of the diameter of the spinal canal has already developed.

Transarticular screw fixation with autograft is an established procedure for the surgical treatment of atlantoaxial instability. Removal of the posterior arch of C1 may affect the rate of fusion. This study assessed the rate of atlantoaxial fusion using transarticular screws with or without removal of the posterior arch of C1. We reviewed 30 consecutive patients who underwent atlantoaxial fusion with a minimum follow-up of two years. In 25 patients (group A) the posterior arch of C1 was not excised (group A) and in five it was (group B). Fusion was assessed on static and dynamic radiographs. In selected patients CT imaging was also used to assess fusion and the position of the screws. There were 15 men and 15 women with a mean age of 51.2 years (23 to 77) and a mean follow-up of 7.7 years (2 to 11.6). Stable union with a solid fusion or a stable fibrous union was achieved in 29 patients (97%). In Group A, 20 patients (80%) achieved a solid fusion, four (16%) a stable fibrous union and one (4%) a nonunion. In Group B, stable union was achieved in all patients, three having a solid fusion and two a stable fibrous union. There was no statistically significant difference between the status of fusion in the two groups. Complications were noted in 12 patients (40%); these were mainly related to the screws, and included malpositioning and breakage. The presence of an intact or removed posterior arch of C1 did not affect the rate of fusion in patients with atlantoaxial instability undergoing C1/C2 fusion using transarticular screws and autograft.

1. A study is presented of 286 extra-articular subtalar arthrodeses done during the years 1958 to 1965 on 258 patients with pes calcaneo-valgus, pes planovalgus, pes varus or flail foot.

2. Certain changes in the surgical technique originally presented by Grice have been made. We have applied the arthrodesis not only to valgus feet but also to varus feet, and we have described the details of the surgical technique as used on the varus foot.

3. In none of our cases was there failure of fusion or reabsorption of the graft. The unsatisfactory results (239 per cent) were caused by residual varus or valgus deformity of the foot.

1. A modification of the Grice extra-articular subtalar arthrodesis is described.

2. The results of this operation are presented.

1. A series of twenty-three compression arthrodeses of the shoulder are reviewed.

2. The review demonstrates compression arthrodesis to be an excellent method of obtaining bony fusion of the shoulder.

3. The consistent success in achieving arthrodesis, in what is to be considered a difficult joint to fuse, is significant in the theory of compression arthrodesis, because the shoulder offers a more perfect example of compression arthrodesis than the knee in that the element of absolute fixation is less obvious.

1. The results of compression arthrodesis of the ankle performed on fifty-five patients (four bilateral) are presented.

2. Fifty per cent of these ankles were immobilised for a total period of no more than eight weeks.

3. Bony fusion occurred in 91 per cent.

4. The subjective result was good or excellent in 88 per cent.

5. The theoretical disadvantages of the transverse incision are not serious in practice.

6. The best position for arthrodesis of the ankle is at, or close to, the right angle.

One hundred cases of Lambrinudi's arthrodesis are reviewed. The shortest follow-up was one year. and the longest twenty-seven years. Thirty-seven per cent were successful. Nineteen per cent were failures; many of these were associated with faulty technique, and one method of operation which gives good results is described.

Success is likely if there is a balance of power between the dorsiflexors and plantarflexors of the ankle, especially if there is some fixed equinus before operation.

Success is less likely when the operation is done for a flail foot. In such circumstances arthrodesis of the ankle may have to be considered subsequently for instability of the lateral ligament, recurrence of dropfoot, or arthritis which may develop in the more active patients.

Age in itself is no bar to success, but pseudarthrosis is more likely to occur in patients over the age of twenty.

1. A simple and effective method of wrist arthrodesis is described. Originally designed for the correction of flexion deformity of the wrist, it is useful also as a routine method of wrist fusion.

2. The results in nineteen cases are reviewed.

A method of intra-articular arthrodesis of the hip is described in which fixation is obtained with a lag-screw. Two main advantages are claimed: first, that it is a compression arthrodesis and gives early bony fusion; and second, that it gives adequate internal fixation in most cases so that the disadvantages of a plaster hip spica are avoided, and the patient may walk with crutches two or three weeks after the operation.

The results were satisfactory in forty-seven of the first fifty cases in which this method of arthrodesis was employed. There were two post-operative deaths and one failure to secure fusion in a case of massive necrosis of the femoral head.

The technique of the transfibular approach for arthrodesis of the ankle joint is described. The results of this operation in a series of thirty cases shows that the procedure is reliable if the technique is carried out faithfully. The two cases in which a first operation failed can both be explained by errors of technique or after-treatment.

The use of autograft bone is the best option when undertaking a procedure that requires bone graft because it is osteogenic, osteoconductive and osseo-inductive. Pain, morbidity and complications associated with harvesting iliac or non-iliac sites occur in between 6% and 30% of cases. An alternative source of graft with possibly a lower morbidity is the intramedullary canal. In this study, 28 patients undergoing 30 arthrodesis procedures on the hindfoot had a mean of 48 cm³ (43 to 50) of bone harvested locally from the hindfoot or the tibial shaft by antegrade or retrograde reaming. No patient sustained a fracture of the calcaneum, talus or tibia. There was no morbidity except for one complication when the reamer breached the medial tibial cortex. This healed uneventfully.

This method of using the reamer–irrigator–aspirator system is an extension of the standard technique of intramedullary reaming of the lower limb: it produces good-quality bone graft with viable growth factors consistent with that of the iliac crest, and donor site morbidity is low. This is an efficient method of obtaining autologous bone for use in arthrodesis of the ankle or hindfoot.

Correction of valgus deformity of the hindfoot using a medial approach for a triple fusion has only recently been described for patients with tight lateral soft tissues which would be compromised using the traditional lateral approach. We present a series of eight patients with fixed valgus deformity of the hindfoot who had correction by hindfoot fusion using this approach.

In addition, we further extended the indications to allow concomitant ankle fusion. The medial approach allowed us to excise medial ulcers caused by the prominent medial bony structures, giving simultaneous correction of the deformity and successful internal fixation.

We had no problems with primary wound healing and experienced no subsequent infection or wound breakdown. From a mean fixed valgus deformity of 58.8° (45° to 66°) pre-operatively, we achieved a mean post-operative valgus angulation of 13.6° (7° to 23°). All the feet were subsequently accommodated in shoes. The mean time to arthrodesis was 5.25 months (3 to 9).

We therefore recommend the medial approach for the correction of severe fixed valgus hindfoot deformities.

We analysed the long-term results of arthrodesis of the shoulder after infection in 15 patients. At the time of operation, 14 cultures were positive for Staphylococcus aureus. The mean follow-up was 8.3 years (3 to 14) and 90% of the patients were satisfied with the outcome. There were complications in five patients (33%); in three there was nonunion with loosening of the implant. One patient had a sound bony union but with a persistent sinus six years after arthrodesis and another had a sinus which healed after the metal was removed. Four of these five patients (80%) were heavy smokers (> 20 cigarettes/day). Cancellous bone grafting did not affect the incidence of complications. The mean age of the patients with complications was 58.6 v 48.6 years for those without (p = 0.2808 ; not significant). Those with complications had had more previous operations (6.4 v 2.5, p < 0.05). Antibiotics, as determined by the bacteriological cultures, were administered for six weeks.

The complication rate was higher in patients with active sepsis but the younger the patient and the fewer number of previous operations (< 50 years, < four previous operations), the better was the outcome. Considering the rate of complications, we recommend early surgery in these patients.

1. A technique of arthrodesis of the trapezio-metacarpal joint of the thumb is described. Primary fusion was achieved in thirty-six of thirty-nine cases.

2. Compensatory movement at the adjacent joints permits a good range of thumb movement.

3. Trapezio-metacarpal arthrodesis is the operation of choice for patients under fifty with isolated osteoarthritis of this joint. It is also useful for stabilising the thumb in patients with paralysis of the thumb when adequate muscles for transfer are not available.

1. The Batchelor method of subtalar fusion by a fibular graft inserted through the neck of the talus is described.

2. The results of the operation appear to be satisfactory.

1 . The results of compression arthrodesis of the hip have been studied in fifty-six patients. There was one post-operative death from pulmonary embolism on the tenth day.

2. Bony union for the whole series (fifty-five patients) was achieved in 76·4 per cent. Sound fibrous ankylosis, indistinguishable from bony union clinically and functionally, was achieved in 10·9 per cent. Residual movement occurred in 12·7 per cent.

3. Thirty-five patients were treated by the standard technique of eight weeks in plaster, followed by full weight bearing, irrespective of whether any movement was detected on clinical testing. 82·8 per cent achieved sound bony union; 5·7 per cent achieved sound fibrous ankylosis, and residual movement occurred in 11·4 per cent.

4. Ten patients were treated without plaster protection; six achieved bony union; three had sound fibrous ankylosis and one had residual movement. Healing was delayed in this group and there was more residual deformity.

5. 67·5 per cent of all patients recovered full knee range. Only one patient with reduced range had knee flexion of less than 90 degrees. Twenty-four of the thirty-five patients treated by the standard technique of eight weeks in plaster were examined. Fifteen had full knee movement; in only four was knee flexion less than 120 degrees and in no case was it less than 90 degrees.

6. Return to full activity was rapid. Sixty per cent of patients returned to work within six months and 80 per cent within nine months of surgery. Five of the six patients examined with residual movement in the hip joint were back at work within six months of surgery.

7. This study lends support to the view that arthrodesis of the hip, in the presence of normal function in the opposite hip, is compatible with vigorous and full activity.

1. The results of ischio-femoral arthrodesis for tuberculous arthritis of the hip in thirty-five adults and in twenty-nine children are reported. The "blind" technique of Brittain was used in thirteen patients and the open technique in fifty-one.

2. Bony fusion was obtained by the first operation in thirty-three out of the thirty-five adults and in twenty-three out of twenty-nine children. In children strikingly better results were gained from the posterior open technique than from the original "blind"technique of Brittain.

3. There was no evidence that ischio-femoral arthrodesis in children interfered with the growth of the limb.

The Brittain V-arthrodesis is a satisfactory procedure for osteoarthritis of the hip. It is particularly suitable for elderly patients when the range of hip flexion is less than 60 degrees. If the four deaths are excluded, two-thirds of the patients secured a sound bony fusion. This occurs slowly. All but one of the patients who survived for three years or more after operation had a sound bony fusion. It is evident that the operation, given time, yields a high rate of sound bony fusion in the hip. It seems likely that use of the McLaughlin nail plate would prevent the one serious complication, namely fracture of the shaft of the femur through or immediately below the drill hole made for the fibular graft.

1. A medial approach is preferred for arthrodesis of the wrist in reconstructive surgery because there is no interference with the extensor tendons.

2. The value of pre-operative assessment by a trial period in plaster is mentioned.

3. The technique of operation is described.

4. In the absence of active pronation, screwing the ulna to the radius in 45 degrees of pronation is advised.

5. The necessity for securing haemostasis before closing the wound is emphasised.

6. Thirty-four cases are reviewed. The shortest follow-up was one year and the longest twelve years. The result was satisfactory in all cases. Most patients were discharged from hospital after the plaster had been changed two weeks after operation. Union occurred in about sixteen weeks.

1. This is a simple clinical study of the end-results of arthrodesis of the hip joint in patients followed up and re-examined five to twenty-five years after operation.

2. The study was stimulated by our astonishment at recent reports which suggested that arthrodesis of the hip caused serious operative mortality, a high rate of wound infection, and failure of sound fusion in one of every two cases; and that even when sound fusion was gained there was always pain in the back and usually stiffness of the knee. To say that we were astonished puts it mildly.

3. This review includes 120 patients aged from ten to seventy years, treated for osteoarthritis of the hip joint by intra-articular arthrodesis with the internal fixation of a nail, usually with an iliac graft, and with immobilisation in plaster for not less than four months.

4. Of these 120 patients there was sound fusion of the joint, proved radiographically, in 94 per cent; a mortality of nil; and recovery of free movement of the knee joint to the right angle or far beyond in 91·5 per cent. Almost half of the patients regained normal movement, the heel touching the buttock. Only in eight patients was there less than right-angled flexion.

5. There was no pain in the back—none whatever—in 64 per cent of the patients. In 36 per cent there was some pain or discomfort. One alone said that the low back pain was worse than before the operation. Many others said that pain in the back had been relieved by the operation.

6. It is emphasised that these results were gained only from sound fixation of the joint in the mid-position with neutral rotation, no more abduction than is needed to correct true shortening, and no more flexion of the joint than that with which the patient lies on the table. The limb was immobilised in plaster for at least four months after operation. The stiff knee was mobilised by the patient's own exercise without passive stretching, force or manipulation.

7. Two other groups of patients are considered. There are fourteen treated by fixation of the joint with nail alone, an operation that was never intended to arthrodese the joint and which has long since been abandoned. The other small group is that of patients with old unreduced traumatic dislocation of the hip, a procedure in which the risks of operation are so great and the number of successful results so small as to dissuade us from attempting operative reduction.

8. After successful arthrodesis of the hip joint patients can return to every household activity and every recreation including ski-ing, mountaineering, rock climbing, or whatever else they want.

1. The usual methods of posterior arthrodesis of the lumbo-sacral joint are not satisfactory in cases in which laminectomy has been performed.

2. Estimation of fusion by mobility radiographs is unreliable and cannot distinguish between fibrous ankylosis and bony fusion.

3. Bone grafts inserted from behind between the vertebral bodies almost invariably fail to become incorporated.

4. Intertransverse arthrodesis has given promising results and is probably the best method available at present.

1. The indications for ischio-femoral arthrodesis are considered.

2. The technique of operation through an open posterior approach is described.

3. Indications for the modified Trumble operation are given.

4. The results of ischio-femoral arthrodesis in a series of forty-seven patients (mostly suffering from tuberculous hip disease) are presented.

5. The writers consider that ischio-femoral arthrodesis is the operation of choice in tuberculous disease of the hip, especially in children.

1. Fifty cases of arthrodesis of the hip joint in tuberculous arthritis are analysed; in forty cases the late end-result has been ascertained two or more years after operation.

2. The indications for arthrodesis are discussed. The operation should not be performed when disease is active; it should not be undertaken before the age of twelve to thirteen years; it is not advisable in elderly patients; it may be contra-indicated when there are multiple foci of infection. Subject to these limitations every patient with unsound ankylosis after adequate conservative treatment should be treated by arthrodesis; painful fibrous ankylosis and late onset of deformity are definite indications.

3. Three types of operation have been used: intra-articular arthrodesis; extra-articular ilio-femoral arthrodesis; combined intra- and extra-articular arthrodesis. Extra-articular ilio-femoral arthrodesis is preferred, deformity being first corrected by traction or osteotomy.

4. Post-operation complications were few; the mortality rate was low (2 per cent.).

5. There was bone ankylosis with solid incorporation of the graft in 87·5 per cent., failure of union of the graft (to the trochanter) in 10 per cent., and destruction of the graft in 2·5 per cent.

6. Late end-results show full working capacity in 87·5 per cent. of patients, part working capacity in 2·5 per cent. and inability to work in 7·5 per cent.

The writer wishes to express his thanks to Professor Harry Platt and Professor T. P.. McMurray for criticism and advice in the preparation of this paper, and to Dr F. C. S. Bradbury, Central Consultant Tuberculosis Officer of the Lancashire County Council, for permission to publish these cases.

Our investigations have shown that the late results of tarsal arthrodesis are good. We have endeavoured to find the disadvantages and to stress residual symptoms, but the general mpression after seeing these patients is that they were all well satisfied with the result. We think it should be added that these patients were selected in so far as they were all operated upon by masters of operative technique who were acknowledged authorities in this particular subject. Without the careful attention to detail and to the points discussed, these operations can be dismal failures and a burden to the patients concerned.

1. The anatomical and physiological principles underlying the operation of ischio-femoral arthrodesis by an anterior approach are discussed.

2. The technique of the operation is described.

1. A long term review of arthrodesis in the management of hallux valgus and rigidus is presented.

2. This is briefly compared with Keller's operation.

3. Eighty-five per cent of patients had a satisfactory result.

4. The reasons for failure and the errors in operative technique are discussed.

1. A simple cone arthrodesis of the metatarso-phalangeal joint of the big toe based on the Rose and Mann operations is described.

2. New instruments have been devised to simplify the procedure.

3. Thirty-one operations have been performed on twenty-three patients. Bony fusion has occurred in all but one case. There have been no complications.

1. Central dislocation of the hip combined with ilio-femoral intramedullary nailing is a technically difficult operation, but one which, if well done, provides a high percentage of hip fusion without external fixation.

2. Fifteen hips have been operated upon. Twelve have fused; two cannot yet be assessed as the time since operation is too short; and one failed, presumably due to osteoporosis resulting from rheumatoid arthritis.

1. An analysis of 171 cases of compression arthrodesis in the knee is presented.

2. A total success rate of 98·8 per cent was revealed.

3. The average time between operation and walking free of splintage was nine weeks.

4. When the compression was removed, after an average period of four weeks, 88·2 per cent of the knees already showed clinical union.

1. One hundred and forty-two cases of extra-articular arthrodesis of quiescent tuberculous hips with fibrous ankylosis have been reviewed.

2. The methods used were the ilio-femoral graft with and without osteotomy, and the ischio-femoral graft by the Brittain or Foley technique.

3. Success occurs more frequently when the grafting operation is combined with or followed by a femoral osteotomy.

4. It is suggested that this success is due largely to the increased immobilisation afforded by the osteotomy.

5. It appears that equally good results can be obtained with either an ilio-femoral or an ischio-femoral graft in these cases provided that an upper femoral osteotomy is also carried out, preferably at or soon after the grafting operation.

6. An upper femoral osteotomy will frequently convert an unsuccessful extra-articular hip graft into a successful one without further grafting.

1. The technique of compression-arthrodesis of the knee joint is described.

2. Fifteen consecutive cases are reported in which clinical union was detected at the first inspection from twelve days to six weeks after operation. By this method the total period of disability is reduced to three months.

3. Three mechanical factors which might be responsible for this very early clinical union are examined: compression is believed to be the main factor, although fixation is also important.

4. A fallacy is exposed in the use of bone grafts for arthrodesis of the knee; the graft is less osteogenic than the substance of the bones which form the joint, and it provides inefficient internal fixation.

5. A theory is suggested that compression, even in the presence of slight movement, acts by producing a fixed "hinge" without shearing movement; at this point a bridgehead of flexible osteoid tissue is established in which ossification inevitably takes place despite slight bending movement.

6. A second theory is suggested that high compression forces stimulate early union by liberating bone salts at points of maximum pressure through the action of osteoclasts, and that the local excess of bone salts is redeposited under cellular activity within a range of a few millimetres where there is no pressure.

From 1975 to 1990 we performed subtalar or triple arthrodesis on 54 patients; 48 of them were reviewed after a mean follow-up of 10 years (6 to 15). There were 17 subtalar fusions in 14 patients and 37 triple arthrodeses in 28 patients. We assessed tibiotalar ankle function using the criteria of Mazur which gives a points score of a maximum of 100. Radiological evidence of degenerative change was graded on a scale of 0 to 4.

The mean Mazur score was 85 for the subtalar fusions and 78 for the triple arthrodeses. The radiological score showed no degenerative changes in 36 feet (24 triple and 12 subtalar arthrodeses) and an increase of one grade in 14 feet (10 triple and 4 subtalar), of two grades in three feet (all triple arthrodeses) and of three grades in one foot after a subtalar arthrodesis.

We found no statistically significant difference in the radiological score in unilateral fusions between feet with subtalar and triple arthrodeses and the contralateral foot. In all four feet which showed an increase in degenerative changes of two or more grades, there was an abnormality of the tibiotalar joint before the fusion operation. Of the 14 feet which showed an increase of one grade, there was a similar increase on the contralateral side in nine.

Our findings show that subtalar or triple arthrodesis has little adverse influence on the function of the tibiotalar joint, even after many years.

Twenty consecutive patients treated by arthrodesis for failed knee arthroplasty are reviewed. Eight hinged, five stabilised and seven compartmental prostheses were removed, for infection (15 cases), loosening (4) and instability (1). One patient refused a second-stage operation but the remainder gained sound fusion. Infected knees had a two-stage procedure with temporary insertion of gentamicin-loaded beads after removal of the prosthesis; all infections healed. Six arthrodeses using a Hoffmann-Vidal external fixator resulted in two temporary failures. One Ace-Fischer external fixation was successful. Of 10 primary attempts at arthrodesis with an intramedullary Kuntscher nail, nine were successful; the tenth fused after two more attempts by the same method. The two failures of external fixation and two failures after Charnley single-frame compression done elsewhere were successfully fused with intramedullary nails. Delayed union in three cases fused after prolonged fixation and repeated bone grafts. The indications for and methods of arthrodesis after failed knee arthroplasty are discussed.

1. The results of treatment of twenty-five disintegrated tuberculous hips by excision, arthrodesis and anti-tuberculous drugs are reported.

2. The methods used are described.

3. Sound healing and bony fusion was obtained in all but three of the twenty-five hips treated.

1. Sixty feet operated upon either by triple or pantalar tarsal fusion for instability after poliomyelitis were re-examined ten to twenty-four years later.

2. After triple fusion with preservation of the ankle joint there was a striking absence of late osteoarthritis of the ankle, and only a low incidence of troublesome lateral instability of the ankle. The results were generally good provided the patient had reasonable power of extension of the knee.

3. Triple arthrodesis for completely flail foot in patients without active muscle control of the knee was often disappointing, so far as the limb as a whole was concerned, because of a persistent flexion deformity of the knee which usually necessitated the wearing of an appliance.

4. The results of pantalar arthrodesis for the flail foot were satisfactory. When this operation was performed (with the foot in slight equinus) in patients who lacked active extension of the knee it helped to stabilise the knee in walking by encouraging hyperextension.

1. An operation is described for ischio-femoral extra-articular arthrodesis of the hip joint by posterior open approach, based on the techniques of Trumble and Brittain.

2. The operation has the advantages of affording adequate exposure of the sciatic nerve trunk and permitting visual control of the alignment and penetration of the chisel and graft.

3. The operation has been performed successfully without serious shock or subsequent complications in eighteen cases, mostly of tuberculosis of the hip.

Nine patients underwent arthrodesis of the knee using a customised coupled nail (the Mayday arthrodesis nail), five after infected arthroplasty, one following failed arthrodesis, one for intractable anterior knee pain, one for Charcot instability and one after trauma. Comparison was made with 17 arthrodeses, eight undertaken using external fixation, four with dual compression plates, and five with long Küntscher nails. Union was achieved in all patients (100%) at a mean time of ten months using the customised implant. There were no complications despite early weight-bearing. No further procedures were required. This contrasted with a rate of union of 53% and a complication rate of 76% with alternative techniques. Of this second group, 76% required a further operative procedure.

We compared the Mayday arthrodesis nail with other techniques of arthrodesis of the knee. The differences in the need for further surgery and occurrence of complications were statistically significant (p < 0.001), and differences in the rate of nonunion and inpatient stay of less than three weeks were also significant (p < 0.05) using Fisher’s exact test.

We conclude that a customised coupled intramedullary nail can give excellent stability allowing early weight-bearing, and results in a high rate of union with minimal postoperative complications.

We report a prospective randomised trial comparing Keller's arthroplasty and arthrodesis of the first metatarsophalangeal joint for the management of symptomatic hallux valgus and hallux rigidus in the older patient. In 81 patients (110 feet), with a minimum of two years follow-up, both procedures gave a similar degree of patient satisfaction and symptom relief. The incidence of metatarsalgia was also similar. As there were no obvious advantages to arthrodesis, and since six out of 50 arthrodesed toes required revision, we suggest that Keller's arthroplasty is the better operation in these patients.

1. One hundred cases of arthrodesis of first metatarso-phalangeal joint have been reviewed after a post-operative interval of at least ten years.

2. Seventy-seven per cent of patients were completely satisfied with the late results ; only 9 per cent were dissatisfied.

3. The two major factors leading to poor results were found to be malposition of the arthrodesis, and interphalangeal osteoarthritis.

4. The ideal position for fusion is considered to be in at least 20 degrees of valgus, preferably between 20 and 30 degrees ; between 20 and 40 degrees of dorsiflexion ; and most importantly, neutral rotation.

5. The precise operative technique is not important provided it maintains the position obtained at operation until the arthrodesis is sound.

1. The history of open operations on fractures of the calcaneum is reviewed.

2. A report is given of the results of treatment of comminuted and depressed fractures of the calcaneum by primary arthrodesis by a modified Gallie procedure.

3. Of twenty-nine patients, twenty-seven returned to full employment within an average of 6·4 months. Twenty-five of these returned to their previous jobs.

4. Poor tendo calcaneus function and lateral sub-malleolar pain were found to be closely allied; both complaints were absent in the usually successful case and occurred only where there had been some complication.

5. It is contended that subtalar arthrodesis is a successful method of treatment for this fracture, but that the operation should be performed soon after the injury in order that the deformity may be corrected.

We treated 15 patients by arthrodesis of the knee after removal of an infected total knee arthroplasty, using an Ilizarov ring fixator. Eight had a failed arthrodesis by another technique. The mean age of the patients was 75 years, the mean duration of retention of the frame was 28 weeks, the mean treatment time 51 weeks, and the mean follow-up 52 months. All but one knee fused at the first attempt, a rate of union of 93%. The incidence of complications related to treatment was 80%. The length of treatment and rates of complication were attributed to advanced age and the adverse local clinical factors in these patients. The Ilizarov method is a promising technique for achieving arthrodesis under these circumstances.

1. The risk of injury to the sciatic nerve during closed ischio-femoral arthrodesis by nail and graft has been assessed on the basis of clinical evidence and of anatomical studies in the living and in cadavers.

2. The margin of safety for the nerve is nearly always small.

3. The risk of injury to the nerve is prohibitive when there is marked deformity or hypoplasia of the pelvis. The risk is also increased when the buttock is compressed against the table and, because of the technical difficulties that are entailed, when the hip is in marked flexion. The risk is probably greater in children than in adults.

4. In properly selected cases in which none of these adverse factors is present it is submitted that the risk of nerve injury can be eliminated by proper attention to surgical technique and by the observance of certain definite precautions.

5. When there is doubt in the surgeon's mind about his ability to complete the operation without injuring the nerve the closed technique should be abandoned in favour of the open posterior approach.

Between June 1991 and May 1996 we carried out arthrodesis on 15 patients with flail or partially flail wrists using an AO/ASIF dynamic compression plate (DCP) without a bone graft. The wrist was approached through the second extensor compartment. The minimum follow-up was for 24 months with a mean of 34.2 months. All 15 wrists fused without major complications at a mean of 11.9 weeks. Stabilisation improved the function of the hand affected with paralysis and the appearance of the extensively paralysed upper limb with a flail hand. In the absence of bony abnormality fusion can be obtained with a DCP alone without the need for bone grafting.

Techniques are described by which metal implants can be designed and produced to fit precisely a bony site at a subsequent operation. CT scans and solid modelling were used to produce an accurate three-dimensional representation of the surface of the bone. These techniques were applied to the production of an internal fixation device for shoulder arthrodesis after the resection of a neoplasm of the proximal humerus. The reconstruction utilised a free vascularised fibular graft between the scapula and the distal humeral remnant, fixation being secured with the custom-made implant.

Achieving arthrodesis of the ankle can be difficult in the presence of infection, deformity, poor soft tissues and bone loss. We present a series of 48 patients with complex ankle pathology, treated with the Ilizarov technique. Infection was present in 30 patients and 30 had significant deformity before surgery. Outcome was assessed clinically and with patient-reported outcome measures (Modified American Orthopaedic Foot and Ankle Society (MAOFAS) scale and the Short-Form (SF-36)). Arthrodesis was achieved in 40 patients with the Ilizarov technique alone and in six further patients with additional surgery. Infection was eradicated in all patients at a mean follow-up of 46.6 months (13 to 162). Successful arthrodesis was less likely in those with comorbidities and in tibiocalcaneal fusion compared with tibiotalar fusion. These patients had poor general health scores compared with the normal population before surgery. The mean MAOFAS score improved significantly from 24.3 (0 to 90) pre-operatively to 56.2 (30 to 90) post-operatively, but there was only a modest improvement in general health; the mean SF-36 improved from 44.8 (19 to 66) to 50.1 (21 to 76). There was a major benefit in terms of pain relief. Arthrodesis using the Ilizarov technique is an effective treatment for complex ankle pathology, with good clinical outcomes and eradication of infection. However, even after successful arthrodesis general health scores remain limited. Cite this article: Bone Joint J 2013;95-B:371–7

Aims. Arthrodesis is rarely used as a salvage procedure for patients with a chronically infected total knee arthroplasty (TKA), and little information is available about the outcome. The aim of this study was to assess the reliability, durability, and safety of this procedure as the definitive treatment for complex, chronically infected TKA, in a current series of patients. Methods. We retrospectively identified 41 patients (41 TKAs) with a complex infected TKA, who were treated between 2002 and 2016 using a deliberate, two-stage knee arthrodesis. Their mean age was 64 years (34 to 88) and their mean body mass index (BMI) was 39 kg/m. 2. (25 to 79). The mean follow-up was four years (2 to 9). The extensor mechanism (EM) was deficient in 27 patients (66%) and flap cover was required in 14 (34%). Most patients were host grade B (56%) or C (29%), and limb grade 3 (71%), according to the classification of McPherson et al. A total of 12 patients (29%) had polymicrobial infections and 20 (49%) had multi-drug resistant organisms; fixation involved an intramedullary nail in 25 (61%), an external fixator in ten (24%), and dual plates in six (15%). Results. Survivorship free from amputation, persistent infection, and reoperation, other than removal of an external fixator, at five years was 95% (95% confidence interval (CI) 89% to 100%), 85% (95% CI 75% to 95%), and 64% (95% CI 46% to 82%), respectively. Reoperation, other than removal of an external fixator, occurred in 13 patients (32%). After the initial treatment, radiological nonunion developed in ten knees (24%). Nonunion was significantly correlated with persistent infection (p = 0.006) and external fixation (p = 0.005). Of those patients who achieved limb salvage, 34 (87%) remained mobile and 31 (79%) had ‘absent’ or ‘minimal’ pain ratings. Conclusion. Knee arthrodesis using a two-stage protocol achieved a survivorship free from amputation for persistent infection of 95% at five years with 87% of patients were mobile at final follow-up. However, early reoperation was common (32%). This is not surprising as this series included worst-case infected TKAs in which two-thirds of the patients had a disrupted EM, one-third required flap cover, and most had polymicrobial or multi-drug resistant organisms.

Aims. Arthroplasty for end-stage hallux rigidus (HR) is controversial. Arthrodesis remains the gold standard for surgical treatment, although is not without its complications, with rates of up to 10% for nonunion, 14% for reoperation and 10% for metatarsalgia. The aim of this study was to analyze the outcome of a double-stemmed silastic implant (Wright-Medical, Memphis, Tennessee, USA) for patients with end-stage HR. Methods. We conducted a retrospective review of 108 consecutive implants in 76 patients, between January 2005 and December 2016, with a minimum follow-up of two years. The mean age of the patients at the time of surgery was 61.6 years (42 to 84). There were 104 females and four males. Clinical, radiological, patient reported outcome measures (PROMS) data, a visual analogue score (VAS) for pain, and satisfaction scores were collected. Results. The survivorship at a mean follow-up of 5.3 years (2.1 to 14.1) was 97.2%. The mean Manchester Oxford Foot and Ankle Questionnaire (MOXFQ) scores improved from 78.1 to 11.0, and VAS scores for pain from 7/10 to 1.3/10. The rate of satisfaction was 90.6%. Three implants (2.8%) required revision; one for infection, one-month postoperatively, and two for stem breakage at 10.4 and 13.3 years postoperatively. There was a 1.9% reoperation rate other than revision, 23.1% of patients developed a minor complication, and 21.1% of patients had non-progressive and asymptomatic cysts on radiological review. Conclusion. We report a 97.2% survivorship at a mean follow-up of 5.3 years with this implant. We did not find progressive osteolysis, as has been previously reported. These results suggest that this double-stemmed silastic implant provides a predictable and reliable alternative with comparable outcomes to arthrodesis for the treatment of end-stage HR.

Salvage of a failed total ankle replacement is technically challenging and although a revision procedure may be desirable, a large amount of bone loss or infection may preclude this. Arthrodesis can be difficult to achieve and is usually associated with considerable shortening of the limb. We describe a technique for restoring talar height using an allograft from the femoral head compressed by an intramedullary nail. Three patients with aseptic loosening were treated successfully by this method with excellent symptomatic relief at a mean follow-up of 32 months (13 to 50)

Aims

This study aimed to investigate the risk of postoperative complications in COVID-19-positive patients undergoing common orthopaedic procedures.

We describe the results of arthrodesis for the treatment of recurrent acute neuropathic bone disease in 24 feet and of chronic disease with deformity in 91 feet, undertaken between January 1984 and December 2003. All were due to leprosy. Correction of the deformity was achieved in 80 of 106 feet (76%) and fusion in 97 of 110 feet (88%). In the 24 feet in which recurrent neuropathic bone disease was the reason for surgery, 17 (71%) obtained stability while in seven (29%) symptoms recurred postoperatively. Complications were experienced following 58 of the 110 operations (53%). In patients presenting primarily with deformity with a minimum follow-up of two years (79 feet), there was a reduced frequency of ulceration in 40 (51%). Normal footwear could be worn by 32 patients (40%) after surgery, while 40 (51%) required a moulded insole. Arthrodesis of the ankle in the neuropathic foot due to leprosy has a good overall rate of success although the rate of complications is high

Arthrodesis of the hip has been employed since the late 19th century. Late complications can arise decades after fusion in patients who were previously asymptomatic. We describe two patients who developed pain in the hip many years after a successful fusion. There was no infection or loosening of the implants. After careful investigation, including oblique radiographs and diagnostic injections of local anaesthetic, the pain was found to be caused by protrusion of the implant. Subsequent removal of the device resulted in complete resolution of the symptoms

Aims

Periprosthetic joint infection (PJI) is a challenging complication of any arthroplasty procedure. We reviewed our use of static antibiotic-loaded cement spacers (ABLCSs) for staged management of PJI where segmental bone loss, ligamentous instability, or soft-tissue defects necessitate a static construct. We reviewed factors contributing to their failure and techniques to avoid these complications when using ABLCSs in this context.

The April 2023 Foot & Ankle Roundup³⁶⁰ looks at: Outcomes following a two-stage revision total ankle arthroplasty for periprosthetic joint infection; Temporary bridge plate fixation and joint motion after an unstable Lisfranc injury; Outcomes of fusion in type II os naviculare; Total ankle arthroplasty versus arthrodesis for end-stage ankle osteoarthritis; Normal saline for plantar fasciitis: placebo or therapeutic?; Distraction arthroplasty for ankle osteoarthritis: does it work?; Let there be movement: ankle arthroplasty after previous fusion; Morbidity and mortality after diabetic Charcot foot arthropathy.

Aims

The aim of this study is to report the implant survival and factors associated with revision of total elbow arthroplasty (TEA) using data from the Dutch national registry.

Charcot osteoarthropathy of the foot is a chronic and progressive disease of bone and joint associated with a risk of amputation. The main problems encountered in this process are osteopenia, fragmentation of the bones of the foot and ankle, joint subluxation or even dislocation, ulceration of the skin and the development of deep sepsis. We report our experience of a series of 20 patients with Charcot osteoarthropathy of the foot and ankle treated with an Ilizarov external fixator. The mean age of the group was 30 years (21 to 50). Diabetes mellitus was the underlying cause in 18 patients. Five had chronic ulcers involving the foot and ankle. Each patient had an open lengthening of the tendo Achillis with excision of all necrotic and loose bone from the ankle, subtalar and midtarsal joints when needed. The resulting defect was packed with corticocancellous bone graft harvested from the iliac crest and an Ilizarov external fixator was applied. Arthrodesis was achieved after a mean of 18 weeks (15 to 20), with healing of the skin ulcers. Pin track infection was not uncommon, but no frame had to be removed before the arthrodesis was sound. Every patient was able to resume wearing regular shoes after a mean of 26.5 weeks (20 to 45)

The August 2024 Foot & Ankle Roundup³⁶⁰ looks at: ESWT versus surgery for fifth metatarsal stress fractures; Minimally invasive surgery versus open fusion for hallux rigidus; Diabetes and infection risk in total ankle arthroplasty; Is proximal medial gastrocnemius recession useful for managing chronic plantar fasciitis?; Fuse the great toe in the young!; Conservative surgery for diabetic foot osteomyelitis; Mental health and outcome following foot and ankle surgery.

Aims

Tibial tubercle osteotomy (TTO) facilitates surgical exposure and protects the extensor mechanism during revision total knee arthroplasty (rTKA). The purpose of this study was to determine the rates of bony union, complications, and reoperations following TTO during rTKA, to assess the functional outcomes of rTKA with TTO at two years’ minimum follow-up, and to identify the risk factors of failure.

Aims

The aims of this study were to: 1) report on a cohort of skeletally mature patients with native hip and knee septic arthritis over a 14-year period; 2) to determine the rate of joint failure in patients who had experienced an episode of hip or knee septic arthritis; and 3) to assess the outcome following septic arthritis relative to the infecting organism, whether those patients infected by Staphylococcus aureus would be more likely to have adverse outcomes than those infected by other organisms.

Aims

The aim of this study was to compare the functional and radiological outcomes and the complication rate after nail and plate fixation of unstable fractures of the ankle in elderly patients.

Aims

Giant cell tumour of bone (GCTB) treatment changed since the introduction of denosumab from purely surgical towards a multidisciplinary approach, with recent concerns of higher recurrence rates after denosumab. We evaluated oncological, surgical, and functional outcomes for distal radius GCTB, with a critically appraised systematic literature review.

Aims

To examine the long-term outcome of arthrodesis of the hip undertaken in a paediatric population in treating painful arthritis of the hip. In our patient population, most of whom live rurally in hilly terrain and have limited healthcare access and resources, hip arthrodesis has been an important surgical option for the monoarticular painful hip in a child.

Aims

The aim of this study was to investigate the feasibility of application of a 3D-printed megaprosthesis with hemiarthroplasty design for defects of the distal humerus or proximal ulna following tumour resection.

Arthrodesis of the hip joint performed between the ages of twelve and fifteen years, is the most satisfactory treatment for cases of pathological dislocation after acute suppurative arthritis in infants

Arthrodesis of the knee is a simple and safe operation that ensures stability and freedom from pain. But it is achieved at the expense of movement and occasionally of social acceptability. If arthroplasty is to be recommended, the advantages of arthrodesis must be retained, with the added bonus of a functional arc of movement

1. Arthrodesis of the first metatarso-phalangeal joint combined with excision of those lesser metatarsal heads with fixed subluxation and painful callosities is an excellent treatment for painful hallux valgus with metatarsalgia. 2. A series of thirty feet in twenty-five patients is reported in which this combined operation was done
