The April 2012 Trauma Roundup. 360 . looks at fibula-pro-tibia plating, galeazzi fractures, distal radial fractures in the over 65s, transverse sacral fractures, acute dislocation of the knee, posterior malleolar fractures, immobilising the broken scaphoid, the terrible triad, lower limb amputation after trauma, and whiplash injuries

1. The bad reputation of fractures of the scaphoid bone is based on a) past disasters caused by inadequate splintage and premature resort to operation; and b) selection of disabling cases for publication. 2. The results obtained in five series comprising over 1,000 fractures suggest that 95 per cent of adequately studied fractures less than a month old unite if properly treated. 3. Sixty cases of established non-union have provided evidence that disability is almost always the result of further injury and that the disability is usually relieved by a short time in plaster. 4. There is no evidence to support the widely held beliefs that a) union by bone can occur only if the fracture is immobilised throughout the process; and b) union after prolonged immobilisation is due to the immobilisation. 5. A policy of treating the wrist and not merely its radiological appearances is advocated

A protocol for the treatment of subacute haematogenous osteomyelitis has been used and evaluated in 71 children. A group of 26 children with a radiologically "aggressive" lesion had biopsy followed by antibiotics and immobilisation for six weeks. A group of 45 children with 48 cavities in the metaphysis or the epiphysis or both was further subdivided according to the presence or absence of clinical signs of pus at subperiosteal level or in a joint. Children with evidence of pus had operation followed by antibiotics and immobilisation while the remaining children were treated similarly but without operation. Intravenous cloxacillin or flucloxacillin and benzylpenicillin were given in hospital for 48 hours and oral antibiotics and immobilisation were then continued at home for six weeks. Staphylococcus aureus was the only pathogen cultured. In all, 91% were cured by a single course of treatment. Of the 48 metaphysial and epiphysial lesions, 77% were treated without operation; and of these, 87% were cured by a single course of treatment, this figure reaching 94% in children under 11 years old

We retrospectively evaluated the clinical and radiological outcomes of a consecutive cohort of patients aged > 70 years with a displaced fracture of the olecranon, which was treated non-operatively with early mobilisation. We identified 28 such patients (27 women) with a mean age of 82 years (71 to 91). The elbow was initially immobilised in an above elbow cast in 90° of flexion of the elbow for a mean of five days. The cast was then replaced by a sling. Active mobilisation was encouraged as tolerated. No formal rehabilitation was undertaken. At a mean follow-up of 16 months (12 to 26), the mean ranges of flexion and extension were 140° and 15° respectively. On a visual analogue scale of 1 (no pain) to 10, the mean pain score was 1 (0 to 8). Of the original 28 patients 22 developed nonunion, but no patients required surgical treatment. . We conclude that non-operative functional treatment of displaced olecranon fractures in the elderly gives good results and a high rate of satisfaction. .

Thirty-five patients (28 children and seven adults) were reviewed six months to 22 years after sustaining the common childhood fracture of the intercondylar eminence of the tibia. The aim was to assess both short-term and long-term results and prognosis by clinical and radiological examination and to discover whether conservative treatment was adequate for those severe fractures where a fragment of the tibial crest had been totally displaced. All the less severe fractures and 14 of the 17 severe fractures were treated conservatively. Early improvement occurred in more patients when the knee was immobilised in extension rather than in flexion, but long-term results were similar. Seven patients had slight discomfort, two of whom had had operative treatment. Radiographs of all patients showed a projection at the fracture site but its size did not correlate with the extent of displacement of the fragment nor with the degree of discomfort suffered; in the severe group a smaller projection developed after open reduction and after immobilisation in extension than after immobilisation in flexion. There was no instability due to functional lengthening of the cruciate ligaments and no increased incidence of degenerative change

1. The method of treatment of a mallet finger deformity by immobilisation in a plaster in the position of hyperextension of the distal interphalangeal joint and flexion of the proximal interphalangeal joint is, on the whole, unsatisfactory because the splint is difficult to apply, it may need to be changed frequently, and it is sometimes complicated by pressure sores. 2. In many cases the deformity is still present after six weeks of adequate immobilisation, but gradual improvement from the contraction of fibrous tissue occurs for up to six months. Therefore an assessment of the results of any method of treatment should be made only after an interval of at least six months. 3. The subjective end results at the end of six months are satisfactory whether or not there has been efficient immobilisation in hyperextension. Few patients have any disability and only rarely is this sufficient to cause interference with normal activities. A high proportion of patients show slight persistent deformity and limitation of movement, and this is seemingly uninfluenced appreciably by the type or duration of treatment. 4. The only treatment necessary for most cases of mallet finger is the application of elastic adhesive strapping or a straight spatula splint in order to relieve the initial discomfort from the injury

Fractures of the hip in children have been associated with a very high rate of serious complications including avascular necrosis (up to 47%) and coxa vara (up to 32%). Over a period of 20 years, we have treated displaced fractures by early anatomical reduction, internal fixation and immobilisation in a spica cast to try to reduce these complications. We have reviewed 18 patients who had a displaced non-pathological fracture of the hip when under 16 years of age. Their mean age at the time of the injury was eight years (2 to 13). They returned for examination and radiography at a mean follow-up of eight years (2 to 17). Each patient had been treated by early (″24 hours) closed or open reduction with internal fixation and 16 had immobilisation in a spica cast. By Delbet’s classification, there was one type-I, eight type-II, eight type-III, and one type-IV fractures. There were no complications in 15 patients. Avascular necrosis occurred in one patient (type-III), nonunion in one (type-II, one of the two patients who did not have a cast) and premature physeal closure in one (type-I). There were no cases of infection or complications as a result of the cast. Our treatment of displaced hip fractures in children by early reduction, internal fixation, and immobilisation in a spica cast gave reduced rates of complications compared with that of large published series in the literature

Fractures of the forearm (radius or ulna or both) in children have traditionally been immobilised in plaster of Paris (POP) but synthetic cast materials are becoming more popular. There have been no randomised studies comparing the efficacy of these two materials. The aim of this study was to investigate which cast material is superior for the management of these fractures. We undertook a single-centre prospective randomised trial involving 199 patients with acute fractures of the forearm requiring general anaesthesia for reduction. Patients were randomised by sealed envelope into either a POP or synthetic group and then underwent routine closed reduction and immobilisation in a cast. The patients were reviewed at one and six weeks. A satisfaction questionnaire was completed following the removal of the cast. All clinical complications were recorded and the cast indices were calculated. There was an increase in complications in the POP group. These complications included soft areas of POP requiring revision and loss of reduction with some requiring re-manipulation. There was an increased mean padding index in the fractures that lost reduction. Synthetic casts were preferred by the patients. This study indicates that the clinical outcomes and patient satisfaction are superior using synthetic casts with no reduction in safety. Cite this article: Bone Joint J 2013;95-B:1285–9

Aims. Cubitus varus is the most common late complication of a supracondylar fracture of the humerus in children. Correction can be performed using one of a number of techniques of osteotomy but each has disadvantages. We describe a new technique for correcting post-traumatic cubitus varus using a lateral closing wedge isosceles triangular osteotomy. Patients and Methods. A lateral closing wedge isosceles triangular osteotomy was performed in 25 patients (15 male and ten female with a mean age of 9.5 years (6 to 12)) between May 2010 and April 2013. All patients had cubitus varus secondary to malunion of a supracondylar fracture, with good function of the elbow and a full range of movement. The osteotomy lines were marked on the bone with an isosceles triangular template made before surgery, after which the osteotomy was performed leaving the medial cortex intact. Fixation was performed using two lateral 2 mm Kirschner (K)-wires and patients were immobilised in an above-elbow plaster. By six to eight weeks callus was present and the wires and cast were removed. Patients were reviewed at four and six weeks, three, six and 12 months and then every two years until skeletal maturity. Clinical and radiographic outcomes were categorised as excellent, good or poor. Results. A total of 23 patients had an excellent and two had a good outcome at a mean final follow-up of 3.4 years (two to four). The mean post-operative carrying angle in the corrected elbow was 11.7° (7° to 18°). One patient fell, displacing the osteotomy, and needed revision of the fixation. No patient had a nerve injury. Conclusion. A lateral isosceles triangular osteotomy and with K-wire fixation is a practical, effective, reliable, safe and simple method of correcting post-traumatic cubitus varus in children. It has inherent stability and excellent cosmesis without prominence of the lateral condyle. . Cite this article: Bone Joint J 2016;98-B:1521–5

This paper reports the cost of outpatient venous thromboembolism (VTE) prophylaxis following 388 injuries of the lower limb requiring immobilisation in our institution, from a total of 7408 new patients presenting between May and November 2011. Prophylaxis was by either self-administered subcutaneous dalteparin (n = 128) or oral dabigatran (n = 260). The mean duration of prophylaxis per patient was 46 days (6 to 168). The total cost (pay and non-pay) for prophylaxis with dalteparin was £107.54 and with dabigatran was £143.99. However, five patients in the dalteparin group required nurse administration (£23 per home visit), increasing the cost of dalteparin to £1142.54 per patient. The annual cost of VTE prophylaxis in a busy trauma clinic treating 12 700 new patients (2010/11), would be £92 526.33 in the context of an income for trauma of £1.82 million, which represents 5.3% of the outpatient tariff. Outpatient prophylaxis in a busy trauma clinic is achievable and affordable in the context of the clinical and financial risks involved. Cite this article: Bone Joint J 2013;95-B:673–7

This paper investigates whether cortical comminution and intra-articular involvement can predict displacement in distal radius fractures by using a classification that includes volar comminution as a separate parameter. A prospective multicentre study involving non-operative treatment of distal radius fractures in 387 patients aged between 15 and 74 years (398 fractures) was conducted. The presence of cortical comminution and intra-articular involvement according to the Buttazzoni classification is described. Minimally displaced fractures were treated with immobilisation in a cast while displaced fractures underwent closed reduction with subsequent immobilisation. Radiographs were obtained after reduction, at 10 to 14 days and after union. The outcome measure was re-displacement or union. In fractures with volar comminution (Buttazzoni type 4), 96% (53 of 55) displaced. In intra-articular fractures without volar comminution (Buttazzoni 3), 72% (84 of 117) displaced. In extra-articular fractures with isolated dorsal comminution (Buttazzoni 2), 73% (106 of 145) displaced while in non-comminuted fractures (Buttazzoni 1), 16 % (13 of 81 ) displaced. A total of 32% (53 of 165) of initially minimally displaced fractures later displaced. All of the initially displaced volarly comminuted fractures re-displaced. Displacement occurred in 31% (63 of 205) of fractures that were still in good alignment after 10 to 14 days. . Regression analysis showed that volar and dorsal comminution predicted later displacement, while intra-articular involvement did not predict displacement. Volar comminution was the strongest predictor of displacement. Cite this article: Bone Joint J 2014;96-B:978–83

We randomly allocated 60 consecutive patients with fractures of the waist of the scaphoid to percutaneous fixation with a cannulated Acutrak screw or immobilisation in a cast. The range of movement, the grip and pinch strength, the modified Green/O’Brien functional score, return to work and sports, and radiological evidence of union were evaluated at each follow-up visit. Patients were followed sequentially for one year. Those undergoing percutaneous screw fixation showed a quicker time to union (9.2 weeks vs 13.9 weeks, p < 0.001) than those treated with a cast. There was a trend towards a higher rate of nonunion in the non-operative group, although this was not statistically significant. Patients treated by operation had a more rapid return of function and to sport and full work compared with those managed conservatively. There was a very low complication rate. We recommend that all active patients should be offered percutaneous stabilisation for fractures of the waist of the scaphoid

An attempt has been made to describe some of the ways in which the element of rotation, which is so important a part of the function of the normal forearm, has a bearing upon the mechanism and treatment of forearm injuries. In particular, distinction is drawn between those injuries in which the shaft of the radius remains in continuity, and those in which there is a complete fracture of the bone. In the former, rotation of the hand in the reduction will be transmitted to the upper end of the radius, and extremes of rotational movement may safely be used to obtain and hold a reduction. In the latter there is likely to be a rotational deformity between the two radial fragments, and the lower radial fragment must be placed in accurate rotational alignment with the upper. In the first group reduction, and in certain cases immobilisation, in full pronation or full supination has been shown to have a place in the treatment of those cases in which a rotation violence has shaped the pattern of the injury. Soft tissues may be used to guide and hold a reduction in a rotational injury, just as in injuries of other types. An injury caused by forced pronation should logically be treated in full supination, for only thus are the intact soft tissues on the "pronation side" of the limb used to the best advantage. In the mechanism of injuries caused by rotation violence it is emphasized that vertical compression is usually the basic force, to which a rotation force may be added by the direction of momentum of the body weight. Such injuries may be grouped into forced rotation injuries (in which the violence applied has taken the limb beyond the normal ranges of rotational movement), and injuries occurring while the limb is pronating or supinating. In the latter group the rotational element determines the pattern of the injury: pronation and flexion are closely allied, and a fracture occurring while the forearm is pronating will develop a backward angulation: so also a supination injury will produce a forward angulation. On the basis of these considerations injuries of the forearm may be classified as follows:. Injuries in which the shaft of the radius remains in continuity. Forced proiiation injuries:. 1) Forward dislocation of the head of the radius. 2) Backward dislocation of the lower end of the ulna. 3) The anterior Monteggia fracture-dislocation. These injuries should be reduced and immobilised in full supination to prevent recurrence of deformity. The lateral and posterior Monteggia injuries are probably variants of dislocation of the elbow and are not caused by rotation violence. In general it is considered that all dislocations of the head of the radius are best treated in full supination. Pronation injuries:. Greenstick fractures of the radius, and of both bones of the forearm, with backward angulation. Reduction of deformity is most easily obtained by manipulating into full supination. Certain fractures may with advantage be immobilised in this position. Supination injuries:. Greenstick fractures of the forearm with forward angulation. Reduction is best obtained by full pronation. Injuries in which the shaft of the radius is in two separate fragments. This group includes all complete fractures of the shaft of the radius and of both bones of the forearm. There is nearly always a rotational deformity between the two radial fragments and its correction is a dominant factor in the treatment

Redisplacement is the most common complication of immobilisation in a cast for the treatment of diaphyseal fractures of the forearm in children. We have previously shown that the three-point index (TPI) can accurately predict redisplacement of fractures of the distal radius. In this prospective study we applied this index to assessment of diaphyseal fractures of the forearm in children and compared it with other cast-related indices that might predict redisplacement. A total of 76 children were included. Their ages, initial displacement, quality of reduction, site and level of the fractures and quality of the casting according to the TPI, Canterbury index and padding index were analysed. Logistic regression analysis was used to investigate risk factors for redisplacement. A total of 18 fractures (24%) redisplaced in the cast. A TPI value of > 0.8 was the only significant risk factor for redisplacement (odds ratio 238.5 (95% confidence interval 7.063 to 8054.86); p < 0.001). The TPI was far superior to other radiological indices, with a sensitivity of 84% and a specificity of 97% in successfully predicting redisplacement. We recommend it for routine use in the management of these fractures in children. Cite this article: Bone Joint J 2013;95-B:563–7

While it is not denied that immobilisation of a diseased joint may be essential, there is a growing mass of evidence that immobilisation in recumbency of the whole patient has severe effects both in the neighbourhood of the actual lesion and upon the skeleton as a whole. Further search for measures to counteract the undesirable skeletal effects of recumbency is much needed

Acute fractures of the scaphoid were randomly allocated for conservative treatment in a Colles’-type plaster cast with the wrist immobilised in either 20° flexion or 20° extension. The position of the wrist did not influence the rate of union of the fracture (89%) but when reviewed after six months the wrists which had been immobilised in flexion had a greater restriction of extension. We recommend that acute fractures of the scaphoid should be treated in a Colles’-type cast with the wrist in slight extension

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

We retrospectively reviewed 183 children with a simple fracture of the distal radius, with or without fracture of the ulna, treated by closed reduction and cast immobilisation. The fracture redisplaced after an initial, acceptable closed reduction in 46 (25%). Complete initial displacement was identified as the most important factor leading to redisplacement. Other contributing factors were the presence of an ipsilateral distal ulnar fracture, and the reduction of completely displaced fractures under deep sedation or local haematoma block. We recommend that completely displaced fractures of the distal radius in children should be reduced under general anaesthesia, and fixed by primary percutaneous Kirschner wires even when a satisfactory closed reduction has been achieved

In this review of 106 cases it appears that immobilisation of a contracted, dislocated or subluxated hip in an extreme position in plaster as the initial treatment caused vascular damage to the femoral epiphysis in approximately 50 per cent of cases. Preliminary frame. reduction in the dislocated hips slowly stretches the soft tissues and allows adaptation of the vessels to the position required for reduction. Open reduction would seem to reduce the incidence of osteochondritic changes. When a hip is immobilised in plaster the extreme of any position, particularly with regard to rotation, should be avoided

1. Sixty fractures of the tibial condyles have been reviewed. Fifty were treated by conservative measures and ten by operative reduction. The fractures are classified and the etiology, age incidence, mechanism of injury, methods of treatment, and results are discussed. 2. The indications for operative reduction are described. 3. The combined split and compression types of fracture give the least satisfactory results. 4. Age is no contra-indication to immobilisation in the treatment of these fractures. 5. Emphasis is laid upon the necessity for immobilisation in the treatment of the associated ligamentous injuries. 6. It is considered that the results justify the policy of treatment described
