We describe the use of Ender nails for the internal fixation of femoral shaft fractures by a closed technique via the greater trochanter and report the treatment of 100 patients with 106 fractures, of which 88 were reviewed 12 months or more after operation. There was primary union in 85 fractures (96.6%) and significant angulation, rotation or leg length discrepancy in eight (9%). We discuss the principles of management which we have evolved

Eighty-seven feet have been reviewed after arthrodesis of the first metatarsophalangeal joint stabilised by chromic catgut. Radiological union was present in 90% of patients at the mean review time of six years. Twenty-four patients had significant metatarsalgia before operation and only two failed to improve afterwards. Excellent or good subjective results were reported in 94% of patients at review. Chromic catgut is advocated as a simple and effective method of stabilising an arthrodesis of the first metatarsophalangeal joint

The place of internal fixation in the treatment of fractures of the shafts of the radius and ulna in adults is discussed, and the results in 130 fractures treated by internal fixation are reviewed. Non-union was found to be the most frequent and serious complication after internal fixation. The incidence of non-union can be greatly reduced if operation is delayed for at least one week, and preferably two to three weeks after injury. Evidence is presented to support the value of delayed operation in the promotion of union of fractures

We performed a prospective randomised trial on matched groups of patients with displaced tibial shaft fractures to compare conservative treatment with closed intramedullary nailing. The results showed conclusively that intramedullary nailing gave more rapid union with less malunion and shortening. Nailed patients had less time off work with a more predictable and rapid return to full function. We therefore consider that closed intramedullary nailing is the most efficient treatment for displaced fractures of the tibial shaft

We treated 22 children with a supracondylar fracture of the humerus and an ipsilateral fracture of the forearm by closed reduction and percutaneous fixation. There were four Gartland type-II and 18 Gartland type-III supracondylar fractures of the humerus. There were fractures of both bones of the forearm in 16 and of the radius in six. Both the supracondylar and the distal forearm fractures were treated by closed reduction and percutaneous fixation. The mean follow-up time was 38.6 months. At the latest follow-up there were 21 excellent or good results and one fair result. There were no cases of delayed union, nonunion or malunion. Five nerve injuries were diagnosed on admission and all recovered spontaneously within eight weeks. No patient developed a compartment syndrome

We treated 25 patients with severely deformed and shortened lower limbs by double oblique diaphyseal osteotomy of the short deformed bone, followed by balanced skeletal traction to correct the alignment and increase the length of the limb. The technique is simple and inexpensive and does not require special equipment. It has the advantage of allowing rapid lengthening and secure healing as the overlap allows end-to-end union with no bone gap. The lengthening achieved ranged from 6 to 16 cm. No serious complications were encountered

The results of immediate plate fixation of 97 open fractures of the tibial shaft in 95 patients are reported. Significant joint stiffness occurred in 11.4% and angular malunion of greater than 5 degrees in any plane was seen in 3.1%. The infection rate was 10.3%. However, even in those cases which develop delayed union or other complications, plate fixation of open fractures can produce excellent recovery of limb function

We observed the healing process under rigid external fixation after Salter-Harris type-1 or type-2 physeal separation at the proximal tibia in immature rabbits. Metaphyseal vessels grew across the gap with little delay; the site of separation then came to lie in the metaphysis and was bridged by endochondral ossification. Union was achieved within two days in all rabbits. Progression of endochondral ossification repaired the separated physis, thus showing ‘primary healing of physeal separation’. This depends on accurate reduction and stable fixation to allow the survival of vessels across the gap

We performed 45 wrist arthrodeses in 43 patients by a modification of the AO technique using the dynamic compression plate. Radiological follow-up was obtained in 41 wrists; all had united at a mean of ten weeks. Clinical follow-up was obtained in 32 wrists. Subjectively, the surgical outcome was satisfactory in 26, marginally satisfactory in two and unsatisfactory in four. This method is safe and reliable. The plate can be contoured to allow a variety of positions of fusion, and gives rigid immobilisation. The rate of union is higher than that for other techniques

A segment of tibia 4.5 centimetres long was removed from one hind limb of fifteen dogs. It was then replaced and the main vasculature was restored by a microsurgical technique. In eight controls the segment was replaced without such restoration. In two-thirds of the former cases the microvascular reconstruction was successful; the rate of infection was found to be reduced, bone union was guaranteed and the rate of union accelerated. Success or failure of the reconstruction was clearly demonstrated in five cases by early bone scanning using technetium-labelled polyphosphate

1. The aetiology of a destructive lesion through a former interspace in a spine fused by ankylosing spondylitis is reviewed. 2. From the findings in three patients treated by anterior spinal fusion, evidence was obtained to show that a stress fracture, originating posteriorly between two fused spinous processes, leads to a pseudarthrosis between two vertebral bodies that may simulate a tuberculous lesion. 3. If spinal fusion is indicated, the anterior approach is recommended, both for direct observation of the lesion and to achieve sound union

1. A case of congenital bowing of the tibia is described in which pseudarthrosis developed and recurred after nine operations performed by the age of ten years. 2. Union was finally secured by a procedure based on deep impaction of the trimmed upper fragment into the reamed-out lower fragment. This was followed by a Boyd type of partial amputation of the foot with calcaneo-tibial arthrodesis. 3. The end-bearing stump four years later is entirely satisfactory and the simple prosthesis gives equality of leg lengths

1. Fifteen cases of bone transplantation for fibrous union of fractures of long bones are described, using boiled minced cancellous bone from cadavers. One transplant became infected but the infection responded to treatment. 2. In one patient with non-union of the shaft of the humerus, bony union was not obtained, but a good functional result obviated further treatment. 3. It is suggested that this relatively simple method of bone transplantation could be used more widely if its potentialities were appreciated more fully

We have carried out a prospective study to determine whether the basic descriptive criteria and classifications of diaphyseal fractures of the tibia determine prognosis, as is widely believed. A number of systems which are readily available were used, with outcome being determined by standard measurements including fracture union, the need for secondary surgery and the incidence of infection. Many validated functional outcomes were also used. The Tscherne classification of closed fractures proved to be slightly more predictive of outcome than the others, but our findings indicate that such systems have little predictive value

We reviewed the outcome of curved intertrochanteric varus osteotomy in the treatment of osteonecrosis of the femoral head in 20 hips. A mean varus angulation of 31° was obtained by the osteotomy. The ratio of intact area on the weight-bearing portion increased from 19% to 61%. The mean elevation and lateral displacement of the greater trochanter were 1.2 cm and 0.5 cm, respectively. These changes in the position of the greater trochanter were very small when compared with those after conventional varus wedge osteotomy. Nonunion or delayed union was not observed. Quantitative analyses showed aggressive bone remodelling in the medial intertrochanteric region. Eighteen hips survived without collapse after a mean follow-up of 48 months. We conclude that curved varus osteotomy can be used to preserve the hip joint in patients with osteonecrosis of the femoral head

In a prospective, controlled study 58 patients aged under 60 years with Colles' fractures were treated either by a forearm plaster or by the application of an external fixator. In 94% of those treated by a fixator it was possible to insert the distal pins of the frame into the fracture fragment, the fixation obtained being sufficient to forgo additional splintage. The external fixator proved more effective at holding the manipulated position, and the radiological loss of position during fracture union was minimal compared with that seen in patients treated in plaster

Between 1993 and 2000 we treated 14 patients with nonunion of fractures of the distal humerus; 11 had already had previous fixation which had failed. The mean time to surgery was 21 months after injury. All the fractures were very low which made it difficult to obtain a firm hold of the small distal fragment. The problem of fixation was addressed by inserting a Coventry infant hip screw into the humeral condyles. The screw has a thread of wide diameter which gives excellent purchase on the small distal fragment. The condyles can then be compressed on to the humeral shaft using a 4.5 mm narrow tibial dynamic plate. Of these 14 difficult cases of nonunion, 12 progressed to union

1. A review of 195 patients with displaced intracapsular fractures of the femoral neck treated by a sliding nail-plate appliance has been presented. 2. The highest failure rate was evident in fractures in women over seventy-five with Grade 4 displacement. 3. The effect of various concomitant factors has been analysed in relation to the end results. 4. Observations have been made on avascular necrosis, its incidence amongst the failures and its association with late segmental collapse after fracture union

Seven patients with nonunion of the scaphoid were treated by a limited approach combining a palmar wedge graft with insertion of a dorsal (retrograde) Herbert screw through small incisions. All patients had palmar bone deficiency and a ‘difficult’ proximal fragment. They were followed up for a minimum of 12 months (12 to 38). Radiological union was achieved in all. In five patients correction of instability of the dorsal intercalary segment which was present before operation, was achieved. On a wrist-scoring chart, all patients had an excellent or good rating. The limited combined approach allows correction of the deformity with rigid fixation and has the advantage of preserving most of the palmar ligaments

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
