Intraoperative pulmonary fat and bone-marrow embolism is a serious complication of bone and joint surgery. We have investigated the occurrence and incidence of intraoperative embolism in patients undergoing elective lumbar spinal surgery with or without instrumentation. Sixty adult patients with lumbar degenerative disease were examined by intraoperative transoesophageal echocardiography while undergoing posterior lumbar surgery. Of these, 40 underwent surgery with instrumentation and 20 without. Moderate to severe (grade 2 or 3 according to the grading scale of Pitto et al) embolic events were seen in 80% of the instrumented patients but in none of the non-instrumented patients (p < 0.001). The insertion of pedicle screws was particularly associated with large numbers of pulmonary emboli, while the surgical approach, laminectomy, disc removal and bone harvesting were associated with small numbers of emboli. We consider that, as in arthroplasty and intramedullary fixation of fractures, these embolic events are relevant to the development of potentially fatal fat embolism during spinal surgery

Aims

The aim of this study was to report the outcomes of different treatment options for glenoid loosening following reverse shoulder arthroplasty (RSA) at a minimum follow-up of two years.

A group of 40 patients with unstable knees due to a combination of a meniscal tear with a rupture of the anterior cruciate ligament was studied to assess the effects of treatment by meniscectomy alone. The results were assessed both subjectively and objectively, but emphasis was placed on the symptoms rather than the physical signs of instability. Meniscectomy alone cured the symptoms of instability in 22 of the patients and a further eight required no further surgical treatment; bucket-handle tears were associated with a good result and posterior-horn tears with a poor result. The remaining 10 patients later underwent an additional procedure to reconstruct the ligament because of persisting symptoms. It was concluded that in patients with this combined lesion the torn meniscus should be dealt with first. In young patients with a posterior-horn tear it would be justifiable to perform a ligamentous reconstruction at the same time as the meniscectomy

We report the long-term results of the surgical treatment of chronic rupture of tendo Achillis using polyester tape. This requires minimal postoperative splintage and allows early mobilisation and a prompt return to work and sport. We reviewed 16 patients (10 women and 6 men) at a mean period of three years after surgery. The median time from injury to operation was 16.8 months (3.9 months to 13 years), and the median age of the patients was 52 years (27 to 78). The median time to full weight-bearing was 40 days and the median time for return to sport was 18 weeks (5.4 to 32). One patient required further surgery and one had numbness along the distribution of the sural nerve. After surgery only two patients had increased dorsiflexion of the ankle compared with the uninjured side. There were no cases of rerupture. We recommend this technique for the treatment of chronic rupture of tendo Achillis

From the European Osteosarcoma Intergroup study 202 patients were assessed with respect to their surgical treatment. Although treated in three different centres the survival of the three groups was identical (57% at five years). Two of the centres had rates of limb salvage of 85% and 83%, respectively, while the third had a rate of 49%. The corresponding risks of local recurrence were 13.3%, 6.8% and 2.5%, with all local recurrences arising in limbs with attempted limb salvage. Local recurrence was closely related to the adequacy of the margins of excision and to the chemotherapeutic response. Patients who had undergone limb-salvage surgery and who developed local recurrence still survival at five years). Of patients who relapsed, 31% of those with local recurrence alone were cured by further treatment, as compared with only 10% of those with metastases. Limb-salvage surgery with effective chemotherapy remains the optimum treatment for osteosarcoma

We report a prospective study of 46 patients with acute complete dislocation of the acromioclavicular joint. They were all treated by suture of the deltoid and trapezius over the clavicle with no repair of the coracoclavicular ligaments, using only temporary fixation with two wires. At operation 43 patients (93.5%) had damage to the trapezius or deltoid or both. The coracoclavicular ligaments were intact in six (13%). Follow-up was from 2 to 7.9 years (mean 5.8), and at the latest review only five patients (10.9%) had redisplacement, due to premature removal of wires for infection in one, to migration of the wires in another and to partial failure of the muscle repair in three. We consider that the deltoid and trapezius attachments are important clinical stabilizers of the clavicle and that their repair, with reinforcement, is a useful addition to any method of surgical treatment

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

Aims

The purpose of this study was to compare the effectiveness of surgical repair to conservative treatment and subacromial decompression for the treatment of chronic/degenerative tears of the rotator cuff.

Aims

The aim of this study was to evaluate blood metal ion levels, leucocyte profiles, and serum cytokines in patients with a total hip arthroplasty (THA) involving modular dual-mobility components.

A prospective randomised trial of surgical treatment for the displaced subcapital femoral fracture in patients of 70 years or more is presented. Two hundred and eighteen patients were randomly allocated into one of three treatment groups: manipulative reduction and internal fixation using Garden screws; Thompson hemiarthroplasty through a posterior (Moore) approach; and Thompson hemiarthroplasty through an anterolateral (McKee) approach. There is no significant difference in the mortality of the internal fixation and posterior arthroplasty groups. Both groups showed a significantly higher mortality than patients operated on through the anterior approach. The technical results of operation were worse in the internally fixed group, with only 40 per cent being satisfactory. Mobilisation was best achieved after the posterior approach. It is concluded that Thompson hemiarthroplasty, using an anterolateral approach, is the safest operation in this group of patients

Twenty patients with complete brachial plexus lesions were reviewed approximately nine and a half years after injury. Thirteen were amputees and seven had received no surgical treatment. Amputation did not alleviate pain and a prosthesis was frequently of no greater use of the patient than the useless limb it replaced: only two of the thirteen amputees were true prosthetic users and they both had dominant limb involvement, the rest adapting easily to being one-handed. Initial treatment should therefore be conservative, with intensive rehabilitation and retraining. It is recommended that amputation should not be considered until a year after injury and only if the flail limb causes repulsion, prevents sporting activities or if the patient has difficulty in converting to the non-dominant limb. In no instance should smputation be done for relief of pain

The clinical, radiographic and pathological features are described of eight cases of a bone tumour which we propose to classify as "malignant osteoblastoma". It presents the characteristics of genuine osteoblastoma but of an aggressive pattern, with more abundant and often plump hyperchromatic nuclei, greater nuclear atypia, and numerous giant cells of osteoclastic type. This rare tumour is regarded as the malignant counterpart of osteoblastoma and appears to be only locally aggressive. It should be separated from conventional osteosarcoma not only because of its peculiar histological pattern, but also because of its different clinical and radiological features and better prognosis. Thus seven of the eight patients were alive and free of disease from one and a half to eleven years after the initial surgical treatment, which in only two cases included amputation. Excision or block resection is the preferred method of treatment

1. A comparison of the results of sixty patients with Pott's paraplegia, half operated upon and half treated conservatively, showed that better results were achieved in a much shorter time in those treated surgically. 2. Extra-pleural antero-lateral decompression is the operation of choice in cases of Pott's paraplegia. 3. The operation should be done as soon as the general condition of the patient allows, and should not be left until the disease is quiescent. 4. The greatest improvement is found in those patients who are still ambulant. 5. Although the gain in patients with complete paraplegia may be small, relief from painful flexor spasms and the healing of bed-sores often justify surgical treatment. 6. Fusion of the vertebral bodies can be carried out at the same sitting using healthy ribs and sometimes cancellous bone, with satisfactory results

1. Twelve children are described in whom gradual limitation of knee flexion developed, without previous injury or inflammation. 2. Clinical and histological investigation showed progressive fibrous degeneration of the vastus intermedius and rectus femoris. 3. As the patella showed signs of retarded development a particular form of myodysplasia, probably congenital, may be supposed. 4. Conservative treatment always failed to stop the progress of this disease. 5. Surgical treatment (Bennett's method or an elongation of the ligamental apparatus of the intermedius muscle) was carried out in ten cases and gave good permanent results. Flexion remained possible only to the extent obtained at operation; rehabilitation gave no further improvement. 6. In the opinion of the author, these cases occur more often than is generally believed, but they are recorded under a different diagnosis and consequently are not submitted to rational treatment

Aims

The purpose of this study was to investigate the potential for achieving local and systemic control after local recurrence of a chondrosarcoma of bone

Somatosensory evoked potentials (SSEPs) measure the conduction pathways from the periphery to the brain and can demonstrate the site of neurological impairment in a variety of locomotor conditions. SSEPs were studied in 44 children (64 feet) with surgically corrected club feet. Four children had unreproducible responses, 18 showed abnormal recordings and 22 showed normal responses. In a further 31 feet (21 children) subjected to motor electrophysiological tests, 16 (52%) were abnormal. Overall, 44 of 95 feet (46%) showed abnormal SSEPs or motor electrophysiological tests. Neurological abnormality was related both to the severity of the deformity and the surgical outcome. It was seen in 38% of feet with grade-2 and in 53% of feet with grade-3 deformity. A fair surgical result was obtained in 36% of feet with a conduction deficit and in only 6% with no abnormality. These results suggest an association between neurological abnormality as demonstrated by SSEPs or motor electrophysiological studies and the severity of deformity in club foot and its response to surgical treatment

Aims

Fungal prosthetic joint infections (PJIs) are rare and account for about 1% of total PJIs. Our aim was to present clinical and microbiological results in treating these patients with a two-stage approach and antifungal spacers.
