Nine patients with nonunited humeral shaft fractures were treated by open reduction and internal fixation with an intramedullary fibular bone graft and a compression plate. Fixation of the screws was enhanced by passing them through the fibula as well as the two humeral cortices (quadricortical fixation). Eight of the nine fractures united at an average of 3.5 months. Tests on cadaver bones showed that quadricortical fixation was as strong as methylmethacrylate augmentation and significantly better than bicortical fixation

Rigid posterior fixation of the skull to the third, fourth and fifth cervical vertebrae was achieved in three patients who, as a result of operation, had gross instability of the craniocervical junction. An anatomically contoured steel loop was secured to the occiput via small burr holes and to the vertebrae by sublaminar wiring. This technique has the advantage over bone grafting, either alone or with cement, in that it affords rigid stabilisation, allows early mobilisation and may contribute to eventual bony fusion

A case is reported four years after successful total replacement of the left humerus for chronic osteomyelitis of six years' duration, with an axillary sinus that had persisted despite repeated operations and more distally a pathological fracture that had failed to united after bone grafting. The disability was such that the patient had requested amputation, but he returned to his previous work as a driver six months after the total replacement and there has been no recurrence of infection

Fracture of the carpal scaphoid is uncommon in children, but does occur and may fail to unite. Eight patients with established non-union have been reiewed, with an average follow-up of almost four years. All non-unions were grafted with autogenous bone. Excellent clinical and radiological results have been obtained. It is concluded that non-union in children is best managed by bone grafting through the anterior approach. Possible aetiological factors concerned in non-union of scaphoid fractures in this age group are discussed

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

Paraplegia occurred in an adolescent girl with osteogenesis imperfecta after chiropractic manipulation. The child had been able to walk freely out of doors. Complete motor paralysis with sensory sparing resulted due to anterior compression of the cord by spondyloptotic cervical vertebrae. Reconstructed computerised tomography was very helpful in demonstrating the abnormality. Anterior and then posterior decompression relieved the tethered spinal cord and were supplemented with bone grafting. Early diagnosis and surgical treatment will prevent similar neurological accidents

1. Eleven cases of tuberculosis of the pubis are described. 2. The disease is often of insidious onset, and symptoms vary from vague discomfort to incapacitating pain in the region of the symphysis and the groin. 3. Abscess formation is common and was present in nine of the eleven patients when they first attended. 4. The lesion has a good prognosis and responds well to simple curettage. 5. In this series operation, without bone grafting, has not been followed by pelvic instability or back pain

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

The transiliac method of leg lengthening uses a modification of Salter's innominate osteotomy. The bone graft increases the length of the hemipelvis distal to the sacro-iliac joint. Leg-length inequality in 23 patients was treated by this method with an average gain in length of 2.8 cm (2.0 to 3.5). Apart from one residual femoral nerve palsy there were no notable complications. The facility to redirect the acetabulum allowed by the technique, may be useful in cases of potential hip instability or acetabular dysplasia

Aims

The sacrum is frequently invaded by a pelvic tumour. The aim of this study was to review our experience of treating this group of patients and to identify the feasibility of a new surgical classification in the management of these tumours.

We report the results of acetabular reconstruction using a bipolar prosthesis bearing on cancellous bone graft in 37 patients after a minimum of five years. There was a satisfactory clinical outcome in 58% when assessed by pain, range of movement and stability, with greater improvement in the pain score than of the other parameters. Radiological migration of the prosthesis was a frequent finding although this did not always correlate with symptoms. Better results were obtained in cases of primary or secondary protrusio acetabuli than after the revision of previous total arthroplasties

We have examined 167 patients who had a hemiarthroplasty for three- and four-part fractures and fracture-dislocations of the head of the humerus in a multicentre study involving 12 Austrian hospitals. All patients were followed for more than a year. Anatomical healing of the tuberosity significantly influenced the outcome as measured by the Constant score and subjective patient satisfaction. With regard to pain, the outcome was generally satisfactory but only 41.9% of patients were able to flex the shoulder above 90°. The age of the patient and the type of prosthesis significantly influenced the healing of the tuberosity, but bone grafting did not. Achievement of healing of the tuberosity was inferior in institutions at which less than 15 hemiarthroplasties had been performed (Mann-Witney U test, p = 0.0001)

A new method of treating large bony defects of the proximal femur is described. The defect is filled with a large vascular-pedicled bone graft from the iliac crest. The graft, being nourished by the deep circumflex iliac vessels, remains viable and therefore induces rapid healing of the bone. This method of bony replacement encourages adequate excision of potentially malignant bone lesions and provides sufficient mechanical support to allow early walking. Six clinical cases are presented to illustrate its application

Most of what I have said has been said before by various writers. Abduction osteotomy is the recognised form of treatment for developmental coxa vara. The results from this operation are usually good. But the results of treatment would probably be better if the condition could be diagnosed before deformity had become disabling, and if the gap in the bone could be closed by other means than osteotomy. Good results of bone grafting in early cases of developmental coxa vara are reported

We have reviewed 22 patients with scaphoid fractures treated by internal fixation with the Herbert screw. Three patients had trans-scaphoid perilunar dislocations, one had an oblique displaced fracture of the waist of the scaphoid and 18 had fractures with delayed or non-union. Corticocancellous bone grafts were added in nine of the cases of non-union. Results were excellent or good in 80% of cases after a mean duration of postoperative immobilisation of four weeks. The technical difficulties are analysed and the problems of applying the jig and of operative exposure are discussed

We describe a technique for slow, progressive, symmetrical distraction of the growth plate using a lightweight dynamic axial fixation system. Results are given for the elongation of 40 bony segments in children with limb-length discrepancies and 60 segments in children with achondroplasia or hypochondroplasia. Increases in limb length of up to 36% were obtained in non-achondroplastic and up to 64.5% in achondroplastic patients. There were no nerve or vascular lesions or bony infections and no case required a bone graft. Pin-track complications occurred in only 1.5%

A treatment regime using electrical stimulation in association with a variety of surgical procedures has improved the prognosis in congenital pseudarthrosis of the tibia--one of the most challenging of all orthopaedic disorders. The technique consists of correction of the tibial deformity, intramedullary fixation and cancellous bone grafting, augmented by electrical stimulation using an implanted bone-growth stimulator. Experience with 27 pseudarthroses in 25 patients is presented; of those, 20 have joined. The cases have been reviewed and the causes of failure analysed. These results offer encouragement to the orthopaedic surgeon treating this difficult condition

A discussion of the essential deformity in calcaneo-valgus feet develops a theme originally put forward in 1961 on the relapsed club foot (Evans 1961). Whereas in the normal foot the medial and lateral columns are about equal in length, in talipes equino-varus the lateral column is longer and in calcaneo-valgus shorter than the medial column. The suggestion is that in the treatment of both deformities the length of the columns be made equal. A method is described of treating calcaneo-valgus deformity by inserting cortical bone grafts taken from the tibia to elongate the anterior end of the calcaneus

1. This paper presents the neurological findings in forty-one patients with rheumatoid arthritis complicated by atlanto-axial subluxation. 2. A method of radiological measurement of the subluxation is described. The extent of neurological involvement was found not to correspond with the degree of subluxation. 3. Fusion of the atlanto-axial complex or of the occipito-atlanto-axial complex is indicated only in patients with progressive neurological signs and in those suffering from acute neurological episodes. 4. Difficulty in obtaining fusion with cancellous bone grafts alone was encountered and we recommend wiring of the laminae C.1 to C.2 in addition

We reviewed 10 patients with symptomatic malunion of a carpal scaphoid fracture. All had displacement with dorsiflexed intercalated segment instability, and suffered from pain, restricted range of movement at the wrist and decreased grip strength. The restriction of flexion-extension and the decreased grip strength correlated with the severity of the DISI deformity. Seven patients had a corrective osteotomy, using an anterior wedge-shape bone graft with internal fixation by Herbert screw, and all had satisfactory results. We believe that symptoms associated with scaphoid malunion are related to consequent carpal deformity
