Twenty complex tibial deformities due to anterior poliomyelitis in 18 patients were corrected by a modified O’Donoghue osteotomy. This technique allowed correction of the deformity in three planes. This was achieved by widening the rectangular window distally to correct both rotation and valgus and by trimming the anterior edges of the step cuts to correct flexion deformity. An above-knee cast was applied for eight to 13 weeks and the patients followed up for a mean of 3.2 years. One of the 18 patients developed delayed union because of fracture of the medial limb of the step cut. The results showed excellent correction of the three-plane deformity and there was no recurrence. This method of osteotomy is a safe and simple procedure which does not require internal fixation and allows correction of torsional and angular deformity

We treated 49 patients at an average age of 80 years (75 to 90) with distal mostly intraarticular humeral fractures by open reduction. There were 8 class A, 13 class B and 28 class C fractures on Muller's classification. The patients were reviewed at a postoperative average of 18 months. The patients' assessment of the result was very good in 31%, good in 49%, fair in 15% and poor in 5%. The flexion-extension range was very good in 41%, good in 44% and fair in 15%. The incidence of implant failure, pseudarthrosis of the olecranon osteotomy and ulnar nerve lesion was no higher in these elderly patients than in younger patients. Old age is not a contraindication to open reduction and internal fixation; it is important to restore full function

We studied the rate of revision in 84 consecutive total hip replacements performed for failed osteosynthesis of femoral neck fractures and compared it with that for primary arthroplasty for osteoarthritis. The age and sex adjusted risk of prosthetic failure was 2.5 times higher after failure of fixation, but all the excess risk was in patients over 70 years of age. There were radiographic signs of loosening of the femoral component at five to 12 years after secondary arthroplasty in six of 33 survivors. In general, the results of secondary replacement were no worse than those obtained after primary arthroplasty for femoral neck fracture. We consider that internal fixation should be the primary procedure: total hip replacement is a safe secondary procedure when osteosynthesis fails

Hyperphosphatasia, or hereditary bone dysplasia with hyperphosphatasaemia, is a rare genetic disorder which is characterised by failure to transform woven into lamellar bone. Clinical, radiological and histological features establish the diagnosis, fractures, deformities, diffuse sclerosis on radiographs and high serum alkaline phosphatase being characteristic. We report the case of a 27-year-old man with follow-up at the same hospital for 20 years. Attempts at treatment with calcitonin and disocium etidronate (EHDP) failed, but stapling of the growth plates at the knee was successfully performed. Transverse "brittle" fractures of the humerus, lower leg and ribs healed normally, but internal fixation and late bone grafting were required for a subtrochanteric stress fracture of the femur at the age of 24 years. At present the patient has no clinical problems and leads a normal life

Eleven patients with metastases in the cervical spine had operations for severe pain due to a pathological fracture which, in eight of the cases, was unstable. Conservative treatment had either failed or was unsuitable. In the first five patients internal fixation with tension band wires and bone grafts was supported by a halo-brace. The method has evolved to the use of posterior instrumentation with laminar wires from two levels above the lesion to two levels below. Stability is increased by the use of bone cement with or without bone autografts applied to one side of the spine. This technique enables the patient to get up within a few days of operation--a great advantage when life expectancy is limited. The operations were successful in all except one case

The hypothesis provides a theoretical justification for, and re-emphasises the practical importance of, close reduction and strict immobilisation in the treatment of fractures of the neck of the femur. It does not support the view that failure of union is caused by vascular damage at the time of the original injury. Unexpected failure of union after nailing is more likely caused by unrecognised imperfection of reduction and the acknowledged deficiencies of internal fixation. Attempts to improve results by passing the sartorius muscle around the fracture (Adams 1956), or by attaching muscle or joint capsule to the proximal fragment, have failed, because such soft tissues are swept off by the acetabular rim when the hip is flexed or medially rotated. Further work is required, both on the more detailed biochemistry of haemarthroses and on the practical and wider implications of the hypothesis

Aims

Use of the direct anterior approach (DAA) for total hip arthroplasty (THA) has increased in recent years due to proposed benefits, including a lower risk of dislocation and improved early functional recovery. This study investigates the dislocation rate in a non-selective, consecutive cohort undergoing THA via the DAA without any exclusion or bias in patient selection based on habitus, deformity, age, sex, or fixation method.

Aims

Adverse local tissue reactions associated with abnormal wear considerably slowed down the general use of metal-on-metal (MoM) hip resurfacing arthroplasty (HRA), now limited to a few specialized centres. In this study, we provide the clinical results of 400 consecutive MoM HRAs implanted more than 20 years ago in one such centre.

To assess the stability of the hip after acetabular fracture, dynamic fluoroscopic stress views were taken of 41 acetabular fractures that met the criteria for non-operative management. These included roof arcs of 45°, a subchondral CT arc of 10 mm, displacement of less than 50% of the posterior wall, and congruence on the AP and Judet views of the hip. There were three unstable hips which were treated by open reduction and internal fixation. The remaining 38 fractures were treated non-operatively with early mobilisation and delayed weight-bearing. At a mean follow-up of 2.7 years, the results were good or excellent in 91% of the cases. Three fair results were ascribed to the patients’ other injuries. Dynamic stress views can identify subtle instability in patients who would normally be considered for non-operative treatment

Aims

The aim of this study to compare 30-day survival and recovery of mobility between patients mobilized early (on the day of, or day after surgery for a hip fracture) and patients mobilized late (two days or more after surgery), and to determine whether the presence of dementia influences the association between the timing of mobilization, 30-day survival, and recovery.

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 treated 110 fractures of the middle third of the clavicle in 108 patients aged between 14 and 66 years, by fixation with 2 mm Kirschner wires. The wire was introduced, using an air drill and a telescoping guide, from the medial into the lateral fragment. The medial end of the wire which perforated the anterior cortex of the medial fragment was bent backwards to prevent migration into the lung or mediastinum. In cases of nonunion and acute fracture in which a bone gap was present, bone graft was laid around the fracture site after internal fixation. All the fractures united. No wires broke but in three patients one migrated before union was achieved. Twenty-one patients failed to return for removal of the wire; nine of them had radiological evidence of union before they were lost to follow-up

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
