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.

1. A method of hip fusion with the aid of a straight intramedullary nail through the ilium and the femur is presented. 2. If properly done, no external fixation is necessary and the patient can be allowed up with crutches ten days after the operation. 3. The method has been used on eighteen hips between 1958 and 1960. There was one case of delayed union due to faulty technique and one case of exacerbation of an old tuberculous infection. Otherwise the follow-up study of the patients revealed good bony fusion in all cases, with no pain in the back or knee

Aims. The aims of our study were to provide long-term information on the behaviour of the thoracolumbar/lumbar (TL/L) curve after thoracic anterior correction and fusion (ASF) and to determine the impact of ASF on pulmonary function. Patients and Methods. A total of 41 patients (four males, 37 females) with main thoracic (MT) adolescent idiopathic scoliosis (AIS) treated with ASF were included. Mean age at surgery was 15.2 years (11 to 27). Mean follow-up period was 13.5 years (10 to 18). Results. For the TL/L curve, the mean curve flexibility evaluated with supine pre-operative bending radiographs was 78.6% (standard deviation 16.5%), with no significant loss of correction observed. On comparing patients with an increase of the TL/L curve increase (> 4º, n = 9, 22%) to those without, significant differences were observed in the correction rate of the MT curve at the final follow-up (p = 0.011), correction loss of the MT curve (p = 0.003) and the proportion of patients who had semi-rigid instrumentation (p = 0.003). Pre-operative percentage predicted forced vital capacity (%FVC) was 80%, dropping to 72% at final follow-up (p < 0.001). The Scoliosis Research Society questionnaire score was not significantly different between patients with and without a TL/L curve increase (p = 0.606). Spontaneous lumbar curve correction (SLCC) was maintained up to 18 years following selective ASF in most patients and demonstrated significant correlation with maintenance of MT curve correction. Conclusion. Maintenance of MT curve correction using rigid instrumentation provided stable SLCC over time. An observed 8% decrease in %FVC indicates that ASF should be reserved for patients with no or only mild pulmonary impairment. Cite this article: Bone Joint J 2016;98-B:997–1002

We describe a surgical procedure used to achieve glenothoracic fusion after one-stage radical, near total scapulectomy for primary or secondary malignant lesions in six patients. The aim was complete excision of the lesion and preservation of the glenoid to provide a fulcrum for movement of the arm. Post-operative assessment involved determination of the range of movement and the application of the Musculoskeletal Tumour Society score and the Constant score to evaluate function. The results showed that a functional range of movement was attainable despite such radical surgery, although there was a considerable reduction in power and ability to lift

The long-term results of 17 patients who had had fusion in situ for severe lumbosacral spondylolisthesis are reported. The average follow-up was 14 years with a range of 7 to 20 years. The average age at operation was 16 years. At follow-up seven patients had occasional backache but only one patient had changed his job and no patient had lost any time off work in the previous year. Nine patients felt that their deformity had been improved and all but one patient still rated the results as excellent up to 20 years after the operation. Although all the patients had persistent foreshortening of the trunk only two patients were aware of any cosmetic deformity. There had been no significant increase in forward slip since the previous follow-up examination five years after the operation. There were no late complications nor significant degenerative changes in the lumbar spine. It is concluded that although fusion in situ does little to improve cosmesis very few patients complain about their appearance and that it is a safe and reliable method of treatment for severe spondylolisthesis which has stood the test of time

Premature fusion of the triradiate cartilage was obtained surgically in 10 three-week-old rabbits, and compared with isolated fusion of the ilio-ischial and of the ilio-pubic limbs of the triradiate cartilage in two further groups of 10 rabbits. Complete fusion caused acetabular dysplasia five weeks after operation in all animals and hip dislocation at nine weeks in half of them; ilio-ischial fusion had a comparable effect. Ilio-pubic fusion had only a minimal effect on acetabular development. The posterior position of the ilio-ischial limb in the acetabulum and its predominance in the formation of the triradiate cartilage in quadrupeds may have contributed to its decisive effect on acetabular development

We examined 16 feet, 33 to 133 months (mean 83) after simultaneous calcaneocuboid and talonavicular fusions performed for a variety of painful disorders of the hindfoot. Objectively, four feet were rated excellent, eight good, four fair and none poor. There was one asymptomatic nonunion of the talonavicular joint. Progressive degenerative arthritis of the ankle was seen in six patients and of the naviculocuneiform joint in seven. Biomechanically, simultaneous calcaneocuboid and talonavicular arthrodesis is better than an isolated talonavicular fusion and is a simple and effective alternative to triple arthrodesis

Assessment of bony union after anterior fusion of the lumbar spine has previously relied on the skilled interpretation of plain radiograph. A biplanar radiographic technique was used to measure small movements between vertebrae and to give a quantitative measure of bony union in 11 patients who had undergone interbody fusion with autogenous bone chips at one level in the lumbar spine. The investigation gave three types of results: bony union, where the fused level showed marked restriction of movement relative to the rest of the lumbar spine; paradoxical movement, where the fused joint showed marked reverse movement (when the patient flexed, the fused level of the lumbar spine extended) which was thought to be due to an anterior bony bar which caused an altered pattern of movement; and non-union, where the level of fusion showed no restriction of movement. The intervertebral joint above the level of fusion was shown to move more than the other joints in the lumbar spine. The study showed that bony union is possible with the use of autogenous cancellous bone chips, and that biplanar radiographic technique can determine the extent of union

Eleven thoracoscapular fusion operations have been done on six patients. The indication is symptomatic winging of the scapula caused by thoracoscapular muscle paresis with intact function in the deltoid. This situation almost exclusively occurs in facioscapulohumeral dystrophy. The operation is successful in achieving stability of the scapula and in greatly improving function and cosmesis. Although the course of this type of muscular dystrophy is variable, the benefits of operation have not deteriorated with progression of the disease over a maximum follow-up period of twenty-three years

One hundred and three patients with scoliosis treated by posterior fusion and Harrington instrumentation are reviewed. The fusion technique described does not require added bone. Walking in a localiser plaster is encouraged as soon as the wound is healed, usually two weeks after operation. The results compare satisfactorily with others published. It is concluded that added bone is not necessary unless neural arch defects are present, and that early walking is advantageous and without risk to the correction

1 . A small series of fractures of the calcaneum with distortion of the subtalar joint has been reviewed. 2. All were treated by subtalar fusion, in most as part of the primary treatment. 3. In all patients the subtalar joint fused by bone without post-operative plaster immobilisation. 4. Plaster immobilisation is not only unnecessary, it is undesirable. 5. Heavy work, including work on ladders and scaffolding, can be undertaken after subtalar fusion

Thirteen patients with dystrophic spinal deformities from neurofibromatosis treated by anterior and posterior fusion have been reviewed. The shortest follow-up was five years, the average seven years. Combined fusion produced satisfactory results in patients with a smooth kyphoscoliosis or with scoliosis without kyphosis, but it was unsatisfactory in patients with an angular kyphoscoliosis. Of the five patients with angular kyphoscoliosis, one had a persistent pseudarthrosis after operation and all had progression of the kyphosis despite the treatment. The morbidity rate also was high in this group of patients. Many of the complications were related to soft-tissue manifestations of the disease. It is recommended that very special attention be paid to the dystrophic angular deformity in neurofibromatosis; even anterior and posterior spinal fusion may fail to control its progression

High definition computed cervical myelograms have been made in flexion and extension in 13 patients with Morquio-Brailsford's disease. We observed that: 1) odontoid dysplasia was present in every case, with a hypoplastic dens and a detached distal portion which was not always ossified; 2) atlanto-axial instability was mild, and anterior atlanto-axial subluxation was absent in most cases; 3) severe spinal cord compression, when present, was due to anterior extradural soft-tissue thickening; 4) this compression was not relieved by flexing or extending the neck and was manifested early in life; 5) posterior occipitocervical fusion resulted in disappearance of the soft-tissue thickening and normalisation of subsequent development of the dens. We conclude that the severity of neurological involvement at the craniovertebral junction was determined by soft-tissue changes, not by the type of odontoid dysplasia nor by subluxation. Posterior occipitocervical fusion proved to be an effective treatment

1. The long-term results of thirty-two naviculo-cuneiform fusions for flat foot have been reviewed sixteen to nineteen years after operation. 2. The initial encouraging results of the operation have not been maintained

We describe a method of internal fixation for occipito-cervical fusion utilising a standard "small fragment" T-plate bent and fixed to the skull with three screws. The lower end of the plate is screwed and wired firmly to the spine of the axis. Of 14 patients so treated, 12 fused, one died and one failed to unite to the skull. Of eight with cord signs, seven remitted or improved and one died

A method of posterior lumbo-sacral fusion is described in which springs are used to fix the grafts and to maintain immobilisation. Fifty patients with lumbar disc degeneration or spondylolisthesis have been reviewed. The results have been assessed clinically by grading the symptoms before and after operation. Stay in hospital has been short and return to work rapid. There has been a high proportion of good results

We have evaluated two methods of surgical treatment of adolescent idiopathic double major scoliosis in 59 patients. In group 1, 31 patients were treated by fusion of the upper curve only. In group 2, 28 patients had lumbar fusions also including most of the lower curve. The magnitude of the lower curve and the correction obtained in traction were good indicators of the correction achieved postoperatively. Forty-four patients were reviewed at a minimum of 10 years after operation. Those in group 1 showed sustained improvement of the lower curve with minimal stiffness and pain. Group 2 patients had lumbar curves of similar severity at review, but had significantly more low back pain and stiffness. The number of lumbar segments which remained mobile appeared to be a critical factor in determining the outcome. Selective fusion of the upper curve in double major scoliosis produces satisfactory results if the lumbar curve is less than 50 degrees. It may also be appropriate for flexible lumbar curves of larger angle

Aims

The aim of this study was to determine how the short- and medium- to long-term outcome measures after total disc replacement (TDR) compare with those of anterior cervical discectomy and fusion (ACDF), using a systematic review and meta-analysis.

A simple modification of Gallie's subtalar fusion is described as a salvage procedure in treating patients with pain from old fractures of the calcaneous involving the subtalar joint. Graft bone for the fusion is taken from the outer half of the calcaneus, thus avoiding disturbance of the tibia or iliac crest. Collapse of the donor site helps to narrow the widened heel present in these patients. The posterior approach allows the peroneal tendons to be freed from any adhesions, and at the same time release of the calcaneo-fibular ligament permits some correction of the valgus of the heel. The early results in six patients have been encouraging

We report three patients having transoral fusion at C2/3 or C3/4 after fractures, with no infections or surgical complications and sound union. The operative technique and the relative merits of different approaches to the upper cervical spine are discussed and the transoral approach to the anterior aspect of the upper three cervical vertebrae is commended to the specialist surgeon
