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. Methods. A follow-up investigation was undertaken on a cohort of 28 children previously reported at a mean of 4.8 years. The present study looked at 26 patients who had an arthrodesis of the hip as a child at a mean follow-up of 20 years (15 to 29). Results. The mean Harris Hip Score (HHS) increased from 39.60 (SD 11.06) preoperatively to 81.02 (SD 8.86; p = 0.041) at final review. At latest follow-up, the HHS was found to be excellent in four patients (15%), good in 11 (42%), and fair in 11 (42%). A total of 16 patients (62%) reported mild low back pain, five (19%) had moderate pain, and five (19%) patients had no back pain. Mild ipsilateral knee pain was reported by 19 (73%), moderate pain by one (4%), and no pain by six (23%) patients. Mild contralateral hip pain was reported by ten patients (38%), and no pain by 16 (62%). The 36-Item Short Form Health Survey scores were very good in four patients (15%), good in 18 (70%), and poor in four (15%), with a mean score of 70.92 (SD 12.65). Of 13 female patients who had given birth, 12 did so with uncomplicated vaginal delivery. All patients had to modify their posture for toileting, putting on lower body clothes, foot care, and putting on shoes. Conclusion. Our results show that with hip arthrodesis, most patients have relatively good function at long-term follow-up, although some pain is experienced in adjacent joints, and modification in some activities of daily living is common.

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

Aim: The long- term results of selective patients undergoing resection of primary malignant tumours followed by allograft arthrodesis of the hip supplemented by vascularised þbula were prospectively studied. Patients and methods: 8 patients underwent resection of the primary malignant tumor of the proximal femur followed by reconstruction with allograft arthrodesis and vascularised þbular graft. The patients were clinically assessed by MSTS functional scoring system and radiologically assessed at regular intervals. All the patients were male with a mean age of 29 years (range18–39). The diagnoses included, Ewingñs sarcoma in three patients, Osteosarcoma and MFH in two patients each and Chondrosarcoma in one patient. Results: 2 patients died of extensive systemic disease without any local recurrence. At a mean follow-up was 112 months (range 28–153), the remaining six patients scored good or excellent in the MSTS scoring system and are engaged in physically active occupations. Radiologically, in three cases there was evidence of fracture of the allograft with loosening of the screws holding the plates but without the failure of the construct. The þbular graft hypertrophied with time in all the cases. Conclusions: Our experience clearly indicates that resection arthrodesis of the hip with allograft supplemented by vascularised þbula is a useful limb salvage procedure with the þbula hypertrophying slowly with time. This is especially so in carefully selected physically active patients who have poor long-term survival with resection followed by custom-made prosthesis

Introduction: Osteochondral reconstruction following tumour resections has a high complication rate. We hypothesized that the vascularised fibular graft as a supplement to the allograft reconstruction following tumour resections would provide a biological solution. Purpose of the study: A prospective study of the results of patients receiving large fragment allografts and vascularised fibular grafts following tumour resections around the hip and the knee. Patients and methods: 18 patients underwent resection of primary malignant bone tumors followed by reconstruction with large fragment allograft and vascularised fibular graft. 8 patients underwent resection arthrodesis of the hip, six underwent resection arthrodesis of the knee and five underwent intercalary resections around the knee followed by a large fragment allograft and vascularised fibular graft reconstruction to span the gap left by resection. The patients were assessed clinically (MSTS scoring system) and radiologically at regular intervals. Results: There were 14 males and 4 females, with a mean age of 26 years (12–70). Mean follow-up was 65 months (8–144). Five patients died of metastatic disease but without local recurrence. In six of the patients with resection arthrodesis of the hip, there was evidence of fracture of the allograft but without the failure of the construct. One fibula fractured but eventually healed uneventfully. There were no cases of non-union in cases of intercalary resections. All the patients scored good or excellent in the MSTS scoring system. Discussion: Our experience clearly indicates that tumour resection followed by reconstruction with large fragment allograft and vascularised fibular graft is a useful limb salvage procedure providing a biological long-term solution with superior results when compared to prosthetic reconstruction

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

A patient with polyostotic fibrous dysplasia had several fractures of the right lower limb. An above-knee amputation was eventually performed, followed by arthrodesis of the hip. Five years later the stump became painful and swelled with dramatic rapidity. Biopsy showed that this was not due to malignant change, but that an aneurysmal bone cyst had developed in association with the fibrous dysplasia

1. A simple technique of arthrodesis of the hip is described. 2. Two triflanged nails are driven across the joint. The joint is not opened. No bone graft and no extensive fixation is used. 3. Symptoms were relieved in 90 per cent of patients and bony union was achieved in 63 per cent. Backache after operation was not a problem. 4. The period of hospitalisation was short and rapid return to heavy work was common

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

A patient is reported who developed a fistula between the hip and the caecum 39 years after arthrodesis of her hip. She presented with a painful right hip and radiographs showed that the Smith-Petersen nail used for arthrodesis had moved up through the acetabulum and into the pelvic cavity. The nail was removed but within a week a fistula which discharged alimentary contents had developed between the hip and the caecum. The patient was treated conservatively, and three weeks later the fistula had closed

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 modified Dunn procedure has the potential to restore the anatomy in hips with slipped capital femoral epiphyses (SCFE) while protecting the blood supply to the femoral head. However, there is controversy about the risks associated with the procedure especially in the most severe capital slips. Therefore, we report on (1) clinical outcome, (2) the cumulative survivorship with endpoints AVN and/or OA progression and (3) radiographic anatomy of the proximal femur at followup in patients treated with a modified Dunn procedure for severe SCFE. We performed a retrospective analysis involving 46 hips of 46 patients treated with a modified Dunn procedure for severe SCFE (slip angle >60°) between 1999 and 2016. Followup averaged 8 years, (range 1–17) with 2 patients lost to followup after one year. The mean age was 13 years (range 9–19 years). Mean preoperative slip angle was 64° (range 60–90) and 14 out of 46 hips (30%) presented with unstable slips. Clinical scores and PROMs were evaluated and the hips were followed standard x-rays. Cumulative survivorship (Kaplan-Meier) with three defined endpoints: (1) AVN; (2) progression by at least one OA grade according to Tönnis; (3) non-preserved hip joint. (1)Mean Harris Hip score (HHS) was 93 points (66–100) and mean Hip Disability and Osteoarthritis Outcome Score (HOOS) was 90 points (67–100) at last followup. (2)Cumulative survivorship was 93% at 10-year followup. Three hips reached an endpoint. Two hips (4%) had AVN, one of them underwent hip arthrodesis. One hip had OA progression. (3)Postoperative slip angle was 7° (1–16). Alpha angle on axial radiograph was 39° (26–71) at followup. 41/44 hips (93%) had no OA (Tönnis 0). The modified Dunn procedure largely corrected slip deformities with low apparent risk of progression to avascular necrosis or osteoarthritis at mean 8-years followup. The AVN rate in severe and unstable (30%) capital slip was 4% (2 hips) with this procedure

We performed arthrodesis with a cobra head compression plate in 18 young adults with severely degenerative arthritis of the hip. The aetiology was trauma in 4 patients, sepsis in 3, slipped upper femoral epiphysis in 3, Perthes disease in one, acute lymphblastic lymphoma in one, alcohol related avascular necrosis in 2, epiphyseal dysplasia in one, multiple osteochondromatosis in one, (bilateral) idiopathic chondrolysis in one and in the remaining case there was no apparent cause. At a mean follow up of 4 years 14 patients were complaining of back pain compared to 4 patients preoperatively. Preoperatively 4 patients had ipsilateral knee pain compared to 5 patients postoperatively. Four patients complained of pain at rest or night. Eleven of the 18 patients have returned to work. The average score of satisfaction on a scale of zero to ten was 7.2, with only 3 patients giving a mark of 4 and below. The management of osteoarthritis of the hip in the young adult is challenging and arthrodesis of the hip is a reasonable option for the very painful arthritic hip

We treated four patients with periacetabular malignant tumours by pelvic reconstruction with a free vascularised fibular graft after resection of the tumour. The mean follow-up period was 32 months (9 to 39). The diagnosis was chondrosarcoma in three patients and osteosarcoma in one. In two patients total resection of the hemipelvis was required and in the other two less, but still massive, resection was undertaken. All were treated with an immediate free vascularised fibular graft which included arthrodesis of the hip and reconstruction of the pelvic ring. One patient died. The other three have remained free from recurrence. Solid union of the graft was achieved between four and 14 months after surgery. Shortening of the involved limbs was less than 2 cm. The patients had no pain and were independent walkers without external support. Emotional acceptance was satisfactory. Our results suggest that reconstruction with the use of a free vascularised graft is an alternative to other types of reconstructive procedure after resection of periacetabular tumours

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."

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

Introduction: The management of a hip destroyed by infection during growth is difficult and controversial. Two clinical cases illustrate differing management options and question what might be the best solution for this problem. Case 1: A 12-year-old girl presented with a Staphylococcus aureus septic arthritis of the left hip. She underwent an arthrodesis of the hip one-year later because of a poor position of the hip. She had 20mm of shortening of the left lower limb. After 6 years of “normal” life she received a total hip replacement when aged 19 years. Since then she has no pain and has 12 mm of shortening of her left lower limb and a mobile left hip (100/0, 40/30, 30/30) and works as a cashier. Case 2 A 2-year-old boy presented with a Salmonella septicaemia and septic arthritis of the right hip. The hip deteriorated but the parents refused a hip arthrodesis. He underwent a Colonna procedure in 1994. Five years later he had developed 50mm of shortening in the right lower limb and he had an epiphysiodesis of the left knee. He is now 17 years old, has a painless hip, satisfactory range of movement (90/0, 0/15, 5/5), a slight limp, equal leg length and enjoys normal teenager activities. Radiographs suggest that he would benefit from a hip replacement

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.

Bradbury, Central Consultant Tuberculosis Officer of the Lancashire County Council, for permission to publish these cases

This is a prospective study assessing the results of patients receiving large fragment allograft and a vascularised fibular graft following primary malignant tumour resections around the hip and the knee. 18 patients underwent tumor resection followed by reconstruction with large fragment allograft and vascularised fibular graft. Eight patients underwent resection arthrodesis of the hip, four underwent resection arthrodesis of the knee and six underwent intercalary resections. Following tumour resection with adequate margins, an appropriate sized allograft fragment was internally fixed with either a plate or an intramedullary nail. A vascularised fibular graft was used to span the gap between the remaining host bones. Osteosarcoma was the commonest diagnosis. The patients were clinically assessed by MSTS functional scoring system and radiologically assessed at regular intervals. The mean age was 26 years (range12–70) and majority of the patients was men. 11 patients received preoperative chemotherapy. Mean follow-up was 85 months (range 8–153). Six patients have died of metastatic disease at a mean of 33 months. Complications included local recurrence in two, deep infection in one and stress fracture of the fibula in two cases. One patient with local recurrence and the other with deep infection underwent an amputation. Majority of the patients had good or excellent MSTS scores at final follow-up and 75% of the patients are engaged in physically active occupations. Graft hypertrophy was evident in majority of the patients. Our experience clearly indicates that reconstruction with large fragment allograft and vascularised fibular graft is a useful limb salvage procedure with the fibula hypertrophying slowly with time. The eventual fracture of the allograft or failure of the allograft-plate composite is to be expected but is not deleterious due to the physiological response of the vascularised fibula to the weight bearing stresses over time. We feel that this biological solution is likely to demonstrate superior long-term results compared to a prosthetic reconstruction
