We have analysed the initial displacement and the retention of position after reduction of 192 spiral fractures of the tibial shaft. In fractures with an initial lateral displacement of one half the width of the shaft or more, successful retention of position after the primary closed reduction was achieved in only 18%. The direction of displacement between the tibial fragments showed little variation; the proximal fragment was always medial and anterior to the distal. This resulted in an increased space between the proximal tibial fragment and the shaft of the fibula in the plane of the interosseous membrane. There was a strong correlation between the initial displacement and the initial shortening. No evidence of a posterior soft-tissue hinge, able to facilitate closed reduction, could be found. Consequently, in treating severely displaced spiral fractures, open reduction and internal fixation or a few weeks' initial calcaneal traction seem to be the rational alternatives

In 1957 Somerville and Scott described their "direct approach" to the management of established congenital dislocation of the hip; arthrography after a period of traction served to distinguish the dislocated from the subluxated hip. We review the long-term outcome of hips which, using their criteria, were subluxated; 72 hips have been reviewed at periods ranging from 15 to 37 years after treatment by traction, closed reduction and femoral osteotomy. The results have been classified clinically and radiologically according to Severin's criteria. There was progressive deterioration with age in both clinical function and radiographic appearance: 48.5% of hips showed evidence of dysplasia or subluxation at review. The results are similar to those found in a series treated by open reduction and limbectomy, differing only in the much lower incidence of degenerative changes after closed reduction

Dislocations of the cervicothoracic junction are frequently missed. Experience of this rare injury over 27 years at the Spinal Injuries Unit in Sheffield confirms that nearly two-thirds were not properly diagnosed on admission. Only two of the 14 dislocations studied were reduced by conservative methods and these were both associated with fractures of the posterior bony elements. Open reduction is necessary to replace pure dislocations at the C7-T1 level. It seems likely that the spinal cord lesion is not influenced by reduction of the displacement. The three patients who had an incomplete lesion of the spinal cord made excellent neurological recoveries although none of the dislocations was reduced. It is concluded that on theoretical grounds it is justified to embark on operative reduction of displacements at this spinal level only if the cord lesion is incomplete, nerve root recovery therefore possible, and if the operation can be brought about soon after the injury

Injuries to the tarsometatarsal (Lisfranc) joint are not common, and the results of treatment are often unsatisfactory. Since no individual is likely to see many such injuries, we decided to make a retrospective study of patients from five different centres. In this way 119 patients with injuries of the Lisfranc joint have been collected. This paper classifies these injuries and describes their incidence, mechanism of production, methods of treatment, results and complications. Sixty-nine of the patients attended for review: 35 of these had been treated by closed methods, 27 had had an open reduction and seven patients had had no treatment. On the basis of our study we suggest that these injuries should be classified according to the type of injury rather than the nature of the deforming force and that their treatment be based upon this classification. It seems that, whatever the severity of the initial injury, prognosis depends on accurate reduction and its maintenance

The results obtained in a consecutive series of thirty-seven Pemberton operations for congenital dislocation or subluxation of the hip are reported. Over the period under review, 1967 to 1973, it was the only type of acetabuloplasty employed at Winford. Unless the mandatory concentric reduction could be obtained with ease, preliminary open reduction was favoured, especially in cases of primary care. Femoral rotation osteotomy was added for marked anteversion. The programme was designed to be complete inside fourteen weeks, and was so for eighteen hips. Secondary acetabuloplasty was performed on hips with instability or dislocation persisting despite previous treatment. The operations were performed from eighteen months to thirteen years of age. One initial failure required a repeat operation which was successful, but one severely dysplastic hip remained so. The average follow-up was six years

1. Six cases of posterior dislocation of the shoulder are described. 2. In four cases the diagnosis was made on clinical grounds. 3. The important clinical signs are the adducted and medially rotated position of the arm, a hard mass posteriorly below the acromion representing the displaced humeral head, and limitation of movement, especially abduction and lateral rotation. 4. In two cases the dislocation was not recognised at the first examination. This confirms the statement of previous authors that posterior dislocation is easily missed. 5. The value of the vertical projection in the radiography of suspected posterior dislocation is emphasised. 6. Reduction was accomplished without difficulty in five cases and the subsequent progress of these was uneventful. In the remaining case reduction was difficult and unstable, and the final recovery incomplete. It is considered that this patient would have been better treated by early open reduction

We describe 24 fractures of the tuberosity of the calcaneus in 22 patients. Three were similar to the type of avulsion fracture which has been well-defined but the remainder represent a group which has been unrecognised previously. Using CT and operative findings we have defined the different patterns of fracture of the calcaneal tuberosity. Ten fractures extended into the subtalar joint, but did not fit the pattern of the common intra-articular fracture as described classically. We have defined a new pattern which consists of a fracture of the medial calcaneal process with a further fracture which separates the upper part of the tuberosity in the semicoronal plane. Non-operative treatment of displaced fractures resulted in a mis-shapen heel and a poor functional outcome. Open reduction and internal fixation with either a plate or compression screw did not give satisfactory fixation. We prefer to use an oblique lateral tension-band wire. This technique gave excellent fixation and we recommend it for the treatment of displaced fractures of the tuberosity of the calcaneus

We reviewed the records of 431 patients who had open reduction and internal fixation of the scaphoid performed by one surgeon (TJH) over a 13-year period. The Herbert bone screw provided adequate internal fixation without the use of plaster immobilisation, promoting a rapid functional recovery. On average, patients returned to work 4.7 weeks after surgery and wrist function was significantly improved, even when the fracture failed to unite. Healing rates for acute fractures were better than those reported for plaster immobilisation and were independent of fracture location. In the case of established nonunions, healing depended on the stage and location of the fracture, but the progress of arthritis was halted and carpal collapse significantly improved. Internal fixation of the scaphoid using the Herbert bone screw, although technically demanding, has few complications and appears to offer significant advantages over other methods of treatment

Aims

The early mortality in patients with hip fractures from bony metastases is unknown. The objectives of this study were to quantify 30- and 90-day mortality in patients with proximal femoral metastases, and to create a mortality prediction tool based on biomarkers associated with early death.

After dislocation of the elbow with avulsion of the medial epicondyle, the management of the latter is controversial. Of 28 children followed up after initial closed reduction of the elbow, 19 had a satisfactory closed reduction of the epicondyle and were treated in plaster. At follow-up, 11 children had a normal elbow and eight had lost an average of 15 degrees of flexion. Nine children had had open reduction and internal fixation of the fragment, one for an open injury, three for displacement of the epicondyle and six for intra-articular entrapment of the fragment. Five of these children had ulnar nerve contusion or compression, four requiring anterior transposition of the nerve. At review, only three had normal elbows and six had lost an average of 37 degrees of flexion. We agree with other authors that surgery is indicated only for children in whom the epicondyle is trapped in the joint or is significantly displaced after closed reduction

The results of treatment of injuries of the thoracic and thoraco-lumbar spine with neurological involvement have been reviewed in a retrospective study of 115 patients, of whom eighty-nine received conservative and twenty-six surgical treatment. Operation was reserved, in general, for patients with irreducible dislocations and incomplete neurological lesions, open reduction and internal fixation being the commonest procedure. Only three patients required a delayed spinal fusion for suspected instability after a period of conservative treatment. On the other hand, ten patients, eight of whom had been treated surgically, were left with severe chronic spinal pain. Of the patients treated conservatively, 35% showed significant neurological improvement compared to 38% of those treated surgically, but the latter group contained a much higher proportion of incomplete lesions with a far better prognosis. It is concluded that the place for early operation might be still further restricted

1. Sixty-eight crush fractures of the articular surface of the lateral tibial condyle have been analysed. 2. Follow-up examination at a minimum of three years after injury was carried out in all cases. 3. The only factors which appeared to influence the results were the extent of the original depression, and if this was severe, the degree of restoration obtained by the treatment. Prolonged plaster fixation was avoided. 4. At review, no patient complained of symptoms which were attributable to damage to ligaments or menisci and no patient had symptoms of late onset. 5. The results suggest that there is nothing to be gained by open reduction if the lateral condyle is depressed by less than 10 millimetres, as conservative treatment gives good results. If the depression is more severe, however, a good result can only be assured if the articular surface is successfully reconstituted, but this is sometimes difficult to achieve. It is not possible to reconstitute the surface by non-operative means

Between 1985 and 1994, 1223 patients with malleolar fractures of the ankle were treated by open reduction and internal fixation with absorbable pins and screws, of whom 74 (6.1%) had an obvious inflammatory foreign-body reaction to the implants. Of these 74, ten later developed moderate to severe osteoarthritis of the ankle despite no evidence of incongruity of the articular surface. The implants used in these patients were made from polyglycolide, polylactide or glycolidelactide copolymer. The joint damage seemed to be due to polymeric debris entering the articular cavity through an osteolytic extension of an implant track. The ten patients had a long clinical course which included a vigorous local foreign-body reaction, synovial irritation and subsequent degeneration. At a follow-up of three to nine years, ankle arthrodesis had been necessary in two patients and is being considered for another two. The incidence of these changes in the whole series was 0.8%, which is not high, but awareness of this possible late complication is essential

Since 1986, we have treated displaced intra-articular fractures of the calcaneum by open reduction through a lateral approach, stable internal fixation and bone grafting. We assessed the results at a mean follow-up of 2.92 years in 44 patients, comparing them with those for 19 patients treated non-operatively. Clinical assessment used the scoring system of Crosby and Fitzgibbons (1990) and radiological measurements were made from lateral, axial and internal oblique views. The articular congruity of the subtalar joint and any arthritic changes were also assessed. We found significantly better results in the operated group with respect to pain, activity, range of movement, return to work and swelling of the hind foot. Radiologically, the operated group showed significantly better scores for articular congruity and arthritic changes. We conclude that the operative treatment of displaced intra-articular fractures of the calcaneum gives better medium-term results than conservative management

Indomethacin is commonly administered for the prophylaxis of heterotopic ossification (HO) after the surgical treatment of acetabular fractures. Non-steroidal anti-inflammatory drugs such as indomethacin, have been associated with delayed healing of fractures and mechanically weaker callus. Our aim was to determine if patients with an acetabular fracture, who received indomethacin for prophylaxis against HO, were at risk of delayed healing or nonunion of any associated fractures of long bones. We reviewed 282 patients who had had open reduction and internal fixation of an acetabular fracture. Patients at risk of HO were randomised to receive either radiation therapy (XRT) or indomethacin. Of these patients, 112 had sustained at least one concomitant fracture of a long bone; 36 needed no prophylaxis, 38 received focal radiation and 38 received indomethacin. Fifteen patients developed 16 nonunions. When comparing patients who received indomethacin with those who did not, a significant difference was noted in the rate of nonunion (26% v 7%; p = 0.004). Patients with concurrent fractures of the acetabulum and long bones who receive indomethacin have a significantly greater risk of nonunion of the fractures of the long bones when compared with those who receive XRT or no prophylaxis

1. Thirty-four cases of displaced fracture of the neck of the radius in children are reviewed with special reference to elbow and forearm function. 2. There were eight poor functional results-four after eighteen closed reductions and four after sixteen open reductions. 3. The causes of the poor functional results are recorded and the complications discussed. Union in a displaced position was the main cause of restricted movement. Deformity of the radial head due to avascular necrosis, and fibrous adhesions between the neck of the radius and the ulna, were other factors. 4. Fractures that were held reduced by Kirschner wires had better results than comparable fractures treated by closed reduction or op en reduction without fixation. 5. It is concluded that all fractures, whatever the age of the child, with angular displacement exceeding 15 degrees need accurate reduction. Closed reduction is not easy, and repeated check radiographs are needed to ensure maintenance of reduction. Certain of these fractures are unstable and require internal fixation with Kirschner wires

We retrospectively reviewed 60 fractures of the tibial plafond treated by either an ankle-sparing diaphyseal-epiphyseal technique using the Ilizarov ring fixator or by an ankle-spanning technique using a monolateral articulated external fixator. The Ilizarov ring fixator was applied in 24 fractures and the monolateral articulated transarticular external fixator in 20. Both techniques were combined with limited open reduction and internal fixation of the articular surface if necessary. Between three and nine years after the injury, all patients returned for clinical and radiological assessment and evaluation of ankle function using the modified Mazur score. There were no significant differences between the two groups in terms of age, gender, mechanism of injury, type of fracture or length of follow-up. The mean functional ankle score was 86 points for the Ilizarov group and 82 points for the articulated fixator group. The difference was not significant (p = 0.07). There were no significant differences between the groups with regard to the radiographic score and late complications. Patients treated with the Ilizarov ring fixator had significantly better ankle and subtalar movement. We conclude that both techniques of external fixation are satisfactory methods of treatment for fractures of the tibial plafond, but that the total arc of movement of the joint is preserved better without bridging the ankle

Fractures of the scaphoid are most common in young men; immobilisation in a cast usually means a long period away from work and athletic activities. Early rigid fixation has been shown to promote a rapid functional recovery, but open reduction and internal fixation is technically demanding with the dangers of damage to the radiocarpal ligaments, the scaphotrapezial joint, and the blood supply of the scaphoid. For minimally displaced or undisplaced B1 or B2 fractures, these problems can be overcome by percutaneous fixation. We report our technique and the results of a pilot study in 15 patients. There was no immobilisation; patients were allowed movement soon after operation, but union was obtained in all at a mean of 57 days (38 to 71). The range of movement after union was equal to that of the contralateral limb and grip strength was 98% of the contralateral side at three months. Patients were able to return to sedentary work within four days and to manual work within five weeks. Our initial results show that percutaneous scaphoid fixation for acute fractures is satisfactory and gives rapid functional recovery

Aims

The glenohumeral joint is the most frequently dislocated articulation, but possibly due to the lower prevalence of posterior shoulder dislocations, approximately 50% to 79% of posterior glenohumeral dislocations are missed at initial presentation. The aim of this study was to systematically evaluate the most recent evidence involving the aetiology of posterior glenohumeral dislocations, as well as the diagnosis and treatment.
