Open reduction and internal fixation was employed in the treatment of 25 severely displaced fractures and fracture-dislocations of the proximal humerus. Our aims were accurate reduction and stable fixation to allow early mobilisation and to achieve full functional recovery. In 15 fractures an AO T-plate was used and in 10 a bent semitubular plate was employed as a blade plate. Excellent or satisfactory results were obtained in all six patients with two-part fractures involving the surgical neck; in four of the five patients with three-part fractures involving the surgical neck and tuberosities; in nine of the 11 patients with fracture-dislocation; and in two of the three patients with split fractures of the humeral head. Overall results were good or satisfactory in 21 of the 25 cases. Unsatisfactory results were associated with rotator cuff damage

We report a retrospective study of 54 acetabular fractures treated by open reduction and internal fixation, with an average follow-up of 9.6 years (3 to 17). Reduction leaving displacement of less than or equal to 2 mm was achieved in 36 hips (67%); good or excellent functional results were obtained in 33 patients (61%). Early complications requiring re-operation included postoperative loss of reduction in one case and an intra-articular screw in another. Arthrodesis or total hip arthroplasty had been performed in 10 patients (19%) who had late symptomatic degenerative changes. Failure to obtain accurate reduction was the most important factor leading to a poor result, but heterotopic calcification caused poor results in seven patients, five of whom had had an anatomical reduction

From an anatomical study and clinical review of fractures of the lateral humeral condyle in children, the following conclusions are drawn. The mechanism of injury is a violent varus force with the elbow in extension, the condyle being avulsed. by the lateral ligament and the extensor muscles. If the fracture is incomplete, with an intact hinge of pre-osseous cartilage medially, the fragment will not be displaced. If the fracture is complete the fragment may be displaced, and open reduction with internal fixation is mandatory. The results of open reduction more than three weeks after the fracture are no better than those of no treatment at all, and may kill the lateral condylar fragment by damaging its blood supply. The major problem of a neglected fracture is tardy ulnar nerve palsy; to avoid this, immediate anterior transposition of the nerve is recommended, operation for the fracture itself being of no benefit

1. Six cases of development of heterotopic bone around joints in association with paralysis from intracranial lesions are presented. It is suggested that such bone may occur more commonly than is realised. 2. The features of these cases are very similar to those seen in association with paraplegia. 3. Extensive new bone is usually associated with fixed contractures. 4. Operation is hazardous in paraplegia but should not necessarily be so in other paralytic conditions. 5. In the presence of returning motor function excision of the bone, allowing correction of the deformity together with some movement, is a worthwhile procedure. In the hip, osteotomy alone usually requires plaster fixation with the attendant risks of venous thrombosis. Previous excision of the bone allows internal fixation of the osteotomy with early mobilisation

1. A series of 110 cases of trochanteric fractures treated by internal fixation with the Capener-Neufeld nail-plate is presented. The age incidence, mortality, complications and functional results are discussed in detail. 2. The results are compared with those of two series of cases treated conservatively: a) 101 cases treated conservatively in hospital; b) 25 cases sent home by reason of shortage of hospital beds. 3. From a consideration of these three series, and from study of similar series of cases reported in the literature, it is concluded that routine operative treatment of trochanteric fractures offers the advantages of lowered mortality, improved function, economy of hospital beds, and greater comfort and mobility of the patient. 4. Certain points in the management of cases during the operation and in the convalescent period are discussed

In a prospective, randomised trial of 81 patients with fractures of the ankle of AO types A, B and C we compared two regimes of postoperative management after internal fixation. The patients were mobilised either non-weight-bearing with crutches or weight-bearing in a below-knee walking plaster. We found a temporary benefit in subjective evaluation only (65 v 50 points, Mann-Whitney test, cft, p = 0.02) for those with a below-knee walking plaster. There were no significant differences between the groups in the loaded dorsal range of movement (25° v 23°, Mann-Whitney test, cft, p = 0.16) or in the overall clinical result. Both treatments were considered to be satisfactory and their choice depends on the ability to mobilise non-weight-bearing, wound healing, the type of work and personal preference

An operation for radical resection of a tumour of the vertebral body and part of the neural arch is described. The approach is posterior and from both sides of the spine. The posterior approach is used to remove the healthy part of the neural arch, mobilise the dura, divide involved nerve roots and carry out the posterolateral parts of the spinal osteotomies or disc divisions. On one side, usually the right, the sides of the vertebral body or bodies are freed and the osteotomies or disc divisions are extended. Then from the other side, a posterolateral thoracotomy or lumbotomy allows completion of the dissection with radical resection by rolling the specimen away from the dura. Ten operations are reported in which up to three and a half vertebrae were resected. Spinal reconstruction was by internal fixation and grafting preferably with vascularised bone. The results were satisfactory after follow-up for as long as eight years

We examined 36 consecutive patients with closed tibial plateau fractures under anaesthesia and by diagnostic and operative arthroscopy before treating them by closed or open reduction and internal fixation. Following the principle of Hohl (1967) (Fig. 1) there were 9 minimally displaced fractures (type I), 6 with local depression (type II), 13 with split depression (type III), 7 with total condylar depression (type IV), and one bicondylar comminuted upper tibial fracture (type V). Seventeen (47%) of knees were found to have associated meniscal injuries which required surgical treatment; five repairs and 12 partial meniscectomies. Neither the type of plateau fracture nor the presence or absence of ligament injury correlated with meniscal tear. There were no intraoperative or postoperative complications from arthroscopy

We analysed the radiographs of 67 patients with displaced malleolar fractures treated by open reduction and internal fixation using absorbable polyglycolide rods. Seventeen patients developed a discharging inflammatory foreign-body reaction, a complication unique to these fixation devices. In 34 patients ovoid osteolytic foci, usually 5 to 10 mm in diameter, appeared within the implant channels six to 12 weeks after the operation. The same lesion occurred in 14 of the 17 patients who developed a foreign-body reaction, whereas only 20 out of the 50 patients with an uneventful course showed osteolytic areas (p less than 0.01). In patients with a foreign-body reaction the osteolytic foci tended to occur in the deepest parts of the implant channels. However, after one year the normal structure of the bone was restored

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

Of 135 consecutive patients admitted with subtrochanteric fractures of the femur, 104 were studied; half had internal fixation with a Zickel nail and half had a nail-plate device. Fractures treated with a Zickel nail had significantly less blood loss during operation and took less time to walk with full weight-bearing, but the incidence of technical error at operation was higher. Errors included malalignment of the cross-pin, penetration of the femoral cortex and comminution of the greater trochanter. There was mechanical failure within one year of surgery in 17% of the nail-plate series but no implant failures in the Zickel nail group within the same period. The total time spent in hospital was similar in both groups. The Zickel nail provides better fixation for subtrochanteric fractures than a simple nail-plate but, because of technical difficulty, its use should be reserved for surgeons of reasonable experience

Rosette strain gauges were attached to the cranial and caudal aspects of the proximal half of the radius in eight skeletally mature female sheep; The sheep's radius has a slight cranially convex curvature. During walking it was deformed so that the cranial surface was subjected to tension aligned along the bone's lon axis, and the caudal surface to compression similarly aligned. The compressive strain on the caudal aspect of the bone was consistently larger (X 1-9) than the tensile strain on the cranial aspect. The thickness of the cortex did not reflect this difference but in younger animals the process of osteonal remodelling seemed further advanced in the cortex which was customarily subject to the larger deformation. The relevance of these findings is discussed in relation to the technique of internal fixation and to our understanding of the basis of the mechanical adaptability of bone

1. In unreduced congenital dislocation of the hip in adults, causing severe symptoms, it seems that there is a place for a calculated abduction type of femoral osteotomy, which should "defunction" a painful false joint. Care should be taken to avoid excessive angulation, which may lead to painful symptoms from contact of the osteotomy apex to the area of the true acetabulum. Genu valgum and lateral rotation deformity are complications, as is failure of union at the osteotomy site. 2. A series of eleven hips in seven patients is reported, in which such an abduction type of osteotomy has been done. Six of these hips have been highly satisfactory. Three have required subsequent operations to correct deformity. Only one has ended up with arthrodesis. In three, results have been only fair. The use of a reversed nail-plate to secure internal fixation is described

1. Fracture of the neck of the femur in childhood and its complications are discussed. 2. The high incidence of these complications is not generally appreciated–in this series of twenty-four patients only eight achieved normal hip joints. 3. The complications are due to the arrangement of the blood supply to the head and neck. Avascular necrosis is unavoidable in a high proportion, and is not directly related to any particular method of treatment. 4. Extreme care and gentleness in handling the injured limb will help to reduce the incidence of deformities; internal fixation is not suitable for the very young as it may predispose to necrosis or may damage the epiphysis. In older children it can be used with care. 5. Where growth is still taking place in the limb the retention of the angle between neck and shaft is most important, as this will prevent coxa vara and progressive shortening with the consequent unsightly Trendelenburg limp

1. A series of one hundred consecutive cases of trochanteric fractures treated conservatively by the authors has been reviewed. 2. Analysis of the results obtained and a study of the relevant literature has led us to the firm conclusion that the routine treatment of this group of fractures should be conservative. 3. Internal fixation should be reserved for those exceptional cases where traction is found to be inadequate: this is specially likely in cases associated with an upper motor neuron lesion, where difficulty is experienced in maintaining reduction owing to muscle spasm. 4. The basal type of fracture offers a special problem because it merges imperceptibly into that of the true transcervical fracture. No difficulty has been experienced in this series in the conservative treatment of such fractures, but we recognise that they might well be regarded as a variety of transcervical fracture and treated by nailing in order to avoid the risk of non-union

Aims

COVID-19 remains the major focus of healthcare provision. Managing orthopaedic emergencies effectively, while at the same time protecting patients and staff, remains a challenge. We explore how the UK lockdown affected the rate, distribution, and type of orthopaedic emergency department (ED) presentations, using the same period in 2019 as reference. This article discusses considerations for the ED and trauma wards to help to maintain the safety of patients and healthcare providers with an emphasis on more remote geography.

Aims

Current guidelines recommend surgery within 48 hours among patients presenting with hip fractures; however, optimal surgical timing for patients on oral anticoagulants (OACs) remains unclear. Individual studies are limited by small sample sizes and heterogeneous outcomes. The aim of this study was to conduct a systematic review and meta-analysis to summarize the effect of pre-injury OACs on time-to-surgery (TTS) and all-cause mortality among older adults with hip fracture treated surgically.

Fifteen patients with ankylosing spondylitis who had developed a severe flexion deformity of the cervical spine which restricted their field of vision to their feet, were treated by an extension osteotomy at the C7/T1 level. The operation was performed under general anaesthesia with the patient in the prone position and wearing a halo-jacket. Three had internal fixation using a Luque rectangle and wiring. Their mean age was 48 years. Before operation the mean cervical kyphosis was 23°; this was corrected to a mean of 31° of lordosis, a mean correction of 54°. All the patients were able to see straight ahead. One patient with normal neurology soon after operation became quadraparetic after one week; two others had unilateral palsy of the C8 root, which improved. There was subluxation at the site of osteotomy in four patients, and two of them developed a pseudarthrosis which required an anterior fusion

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

Biodegradable rods of polyglycolide or lactide-glycolide copolymer were used in the internal fixation of a variety of fractures and osteotomies in 516 patients. A clinically manifest foreign-body reaction occurred in 41 patients (7.9%), producing a fluctuant swelling at the implantation site after an average of 12 weeks. Spontaneous sinus formation or surgical drainage yielded a sterile exudate containing liquid remnants of the degrading implants. After prompt drainage this discharge subsided within three weeks. Histological examination showed a typical nonspecific foreign-body reaction with abundant giant cells both in patients with the reaction and in some patients with an uneventful clinical course. The factors determining the nature of the reaction were probably related to the local capacity of the tissues to clear the polymeric debris. The reactions did not influence the clinical or radiographic results, but recognition of the incidence and the features of the reaction is necessary in view of the increasing use of such implants
