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

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

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

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 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

1. The results of treatment of 117 tuberculous and fourteen other types of infection of the spine in adults by anterior fusion and chemotherapy have been reviewed. 2. It is suggested that anterior fusion is justified because: a) it permits isolation of the organism, and hence the determination of drug sensitivities and appropriate chemotherapy; b) removal of the diseased tissue and the stabilisation of the affected segment by iliac bone grafts can be effected, leading to rapid healing by bony fusion with little further collapse; c) rehabilitation of the patient is hastened; and d) the incidence of reactivation is probably diminished

1. Twelve cases of hydatid disease of bone seen in Kuwait over the last ten years are reported. Ten of the twelve patients were Bedouins. 2. Seven cases were followed up and the results of treatment are discussed. 3. Curettage, formalin swabbing and bone grafts were used as the treatment of choice. 4. There may be a place for a conservative approach in some cases ; one such case reported here has been followed up for ten years. 5. The problem of prevention, especially in a Bedouin area, is briefly discussed

We carried out primary cemented total hip arthroplasty (THA) on 25 hips in 21 patients with developmental dysplasia of the hip, using autogenous acetabular bone grafts. The socket was placed at the level of the true acetabulum and bone from the femoral neck was used as graft. Five hips were excluded, leaving 20 which were followed up for a mean of 12.9 years (10 to 18). The mean modified Merle d’Aubigné and Postel functional scores were 5.6 for pain, 4.3 for mobility and 4.2 for range of movement. Radiological examination showed aseptic loosening in three sockets but not in the stems. The bone grafts had united and showed no evidence of late failure

Aims

The aim of this study was to compare the incidence of anterior knee pain after antegrade tibial nailing using suprapatellar and infrapatellar surgical approaches

In two hospitals, 115 consecutive open femoral shaft fractures were treated by meticulous wound excision and early locked (97) or unlocked (18) intramedullary nailing. All the fractures united; union was delayed in four, three of which required bone grafting. The average range of knee flexion at follow-up was 134 degrees (60 to 148). Five patients had a final range of less than 120 degrees, but three of these improved after manipulation under general anaesthesia. Three patients developed staphylococcal infections and required further surgical treatment. All eventually healed

Aims

Options for the treatment of intra-articular ligament injuries are limited, and insufficient ligament reconstruction can cause painful joint instability, loss of function, and progressive development of degenerative arthritis. This study aimed to assess the capability of a biologically enhanced matrix material for ligament reconstruction to withstand tensile forces within the joint and enhance ligament regeneration needed to regain joint function.

Total hip replacement for adults with unreduced congenital dislocation presents a difficult problem because soft-tissue contractures usually prevent sitting at the normal anatomical level. Extensive soft-tissue division or a high-level acetabulum leads to reduced function and poor fixation of the components. We describe a new technique for hip replacement in such cases. The shortened abductors and flexors are released proximally and excision of the upper third of the ilium allows them to be repaired without tension, while providing bone graft to reconstruct the acetabular roof. We report 12 such replacements in 10 patients with good results and few early complications

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
