We examined seven patients with tarsal tunnel syndrome in one foot caused by talocalcaneal coalition and a ganglion. We excised the coalition and the ganglion in six of them. All the patients had pain, sensory disturbance in the sole, and a positive Tinel’s sign. Older patients with a long history showed atrophy and weakness of the plantar muscles. Talocalcaneal coalition can be diagnosed on a plain lateral radiograph and an anteroposterior radiograph externally rotated 20°, and confirmed by CT. MRI is also useful for diagnosis. The coalitions were medial, and the ganglion had developed from the incomplete part of the coalition; it was multilocular in some patients. After resection, there was early pain relief but sensory disturbances and Tinel’s sign persisted. The postoperative results were excellent in one patient, good in four and fair in one

Aims

The aim of this study was to explore whether time to surgery affects functional outcome in displaced proximal humeral fractures

The bone-marrow oedema syndrome is associated with local vascular disturbances and may be treated either conservatively or by core decompression after which recovery may take several weeks. We describe a 15-year-old girl with bone-marrow oedema of the left acetabulum which was confirmed by MRI. She presented with a four-week history of severe constant pain. Routine blood tests and plain radiographs were normal. She was treated with intravenous infusions of iloprost on five consecutive days (20 μg administered in 500 ml of sodium chloride). Iloprost causes vasodilatation with reduction of capillary permeability and it inhibits platelet aggregation. She had relief from pain at rest after three days of treatment and was completely free from symptoms after two weeks. MRI after six weeks showed almost complete resolution of the marrow oedema and was normal after four months. This is the first report of the pharmacological treatment of the bone-marrow oedema syndrome in children

A description is given of 20 patients with winging of the scapula. The majority had suffered spontaneous severe pain in the region of the shoulder followed about two weeks later by the deformity and associated loss of function. Only in three patients was there a clear history of trauma. Some patients may have strained the arm, but in the majority no single factor heralded the problem. Most of the patients were followed up for more than two years and it became clear that functional recovery could take up to this time to be complete. However, careful examination revealed that often a slight degree of winging remained. No specific treatment apart from gentle physiotherapy was prescribed and certainly no operative procedures. It is considered that a number of these cases were examples of neuralgic amyotrophy

Almost one child in twenty with trisomy 21 will develop spontaneous dislocation of the hip between learning to walk and the age of 10 years. After the age of two years spontaneous habitual dislocation may occur. If left untreated, acute dislocation, subluxation and fixed dislocation follow in sequence. The natural history of the condition is described and the clinical and radiological features of 45 dislocations in 28 patients are presented. Nineteen had received no treatment. The most effective treatment was found to be pelvic or femoral osteotomy, combined with capsular plication, carried out in the phase of habitual dislocation. Once subluxation or fixed dislocation was present, the results of operation were poor and it is not recommended. All patients, even if left untreated, remain mobile. Pain is not a prominent feature

1. Eight cases of monarticular brucellar arthritis in children are described. They have been followed up from between one and six years and all are now fully active and clinically normal. 2. The history was usually short, with limp, swelling of the joint and pain as the presenting symptoms. Constitutional disturbance was slight in all cases. 3. Diagnosis was confirmed by high concurrent serum agglutinin titres which were not found in control children of the same age from the same areas. Mercaptoethanol resistant antibody (IgG) and complement fixing antibodies were also demonstrated in the sera of four cases. One child had a positive blood culture. 4. The condition responded rapidly to rest and splintage and, to date, recovery seems to have been complete

We have undertaken routine ultrasound screening for neonatal hip instability in Coventry since June 1989. Of the 14,050 babies scanned during the first three years, 847 (6%) had ultrasound abnormalities. A grading system, based on the percentage of femoral head coverage, is presented. The proportion of abnormal hips decreased gradually so that by nine weeks, 90% had normal ultrasound appearances. Abnormality was more common in babies with a family history of CDH and in breech presentations. All babies with clinically abnormal hips had an abnormal first ultrasound examination. Five babies not diagnosed by clinical examination and with no risk factors had abnormal ultrasound appearances and were subsequently found to have clinically abnormal hips. Routine ultrasound screening has detected cases which would otherwise have presented late

We report a prospective trial of 66 patients with intraarticular fractures of the calcaneum. All fractures were assessed by CT. Patients with displaced fractures were randomised to receive either conservative (n = 31) or operative treatment (n = 25). Undisplaced fractures (n = 10) were treated conservatively. Operation involved open reduction of the posterior subtalar joint, and fixation with Kirschner wires. All 66 patients were reviewed at a minimum of one year (mean 23 months). After conservative treatment the undisplaced fractures had slightly better results than the displaced fractures. There was no significant difference in outcome between the operatively and the conservatively treated displaced fractures. We have also documented prospectively the natural history of the injury, which is of use in assessing prognosis for both clinical and medicolegal purposes

Venous ulceration is a chronic disabling complication of deep-vein thrombosis. The aim of this study was to estimate the incidence of venous leg ulcers five years or more after total hip replacement (THR) and to investigate some of the clinical features associated with their development. We carried out a postal survey of all patients who had undergone a THR 5 to 12 years previously. Replies from 816 patients showed that 66 (8.1%) had a history of leg ulcers. The prevalence of active ulceration was 2.6% and 43 patients (5.3%) reported developing ulceration since their hip replacement. A clinical review determined that 31 (3.8%) of these were true venous ulcers. The ulcers occurred more commonly on the operated side and developed at a mean of 5.8 years (18 months to 12 years) after the first arthroplasty. A mean of 1.9 arthroplasties (1 to 5) (primary and revision) were carried out before the ulcers appeared. The overall incidence of ulcers was similar to that in the general population

Aims

It is unknown whether kinematic alignment (KA) objectively improves knee balance in total knee arthroplasty (TKA), despite this being the biomechanical rationale for its use. This study aimed to determine whether restoring the constitutional alignment using a restrictive KA protocol resulted in better quantitative knee balance than mechanical alignment (MA).

Static and dynamic measurements of foot pressure have been carried out on three groups of subjects: diabetic patients with neuropathy (with and without a history of ulceration), diabetic patients with no neuropathy, and normal subjects as controls. In many cases both techniques of measurement detected areas of abnormally high pressure under the foot, but in some cases a particularly high-pressure spot was detected on only one of the tests and sometimes both methods were needed to reveal all the areas of the foot which might be considered to be at risk. The dynamic measurements tended to show multiple areas of high pressure better than the static measurements. Our results indicate the importance of making both types of measurement when seeking to devise suitable means of protecting the foot from ulceration

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.

Basilar impression is a well-recognised though rare complication of osteogenesis imperfecta. Three patients, all members of the same family, with advanced basilar impression complicating osteogenesis imperfecta tarda, are described. The clinical features in these cases illustrate the natural history of this condition: from asymptomatic ventricular dilatation, through the foramen magnum compression syndrome, to death from brain-stem compression. The radiological criteria on which the diagnosis is based, are defined. Review of the literature reveals only seven previously documented cases, all in patients with mild forms of osteogenesis imperfecta. The unusually low incidence of basilar impression in osteogenesis imperfecta and its apparent restriction to patients with mild forms of the disease is discussed. The examination of close relatives of patients with basilar impression and osteogenesis imperfecta is emphasised in order to anticipate the onset of severe neurological complications

A series of 75 patients who had undergone anterior cervical fusion between 1965 and 1977 were reviewed. The patients were divided into two groups: those in Group A had had the level of fusion indicated by cine radiography, whereas in Group B the level had been determined by plain radiographs and clinical symptoms and signs. Results showed that cine radiography was the more accurate diagnostic technique. Accurate diagnosis of the level to be fused, the careful clinical selection of patients and sound bony union were found to be vital to the success of anterior cervical fusion. The incidence of pseudarthrosis was significant in single-level fusions and was even greater in double-level fusions and in patients with a history of trauma, especially whiplash injuries. It was rare to develop recurrence of symptoms in adjacent levels after fusion of a level localised by cine radiography

The different methods described in the literature for the reduction of severe spondylolisthesis are reviewed. The case histories of two girls with neurological deficits in their legs due to Grade IV spondylolisthesis are described. Reduction and fusion by the posterior route in a one-stage operation were performed on these patients. For this purpose special instruments have been designed to exert a controlled force on the displaced vertebra in two perpendicular directions. Technical details of the procedure are reported. In both patients intervertebral and posterolateral fusion were carried out. Fusion was successful and redisplacement did not occur. There have been only few descriptions in the literature of a technique that reduces and stabilises spondylolisthesis in one stage. However, only patients with Grade III and IV spondylolisthesis require reduction and in less severe cases fusion without reduction is sufficient

Of 193 children with Perthes' disease at the Texas Scottish Rite Hospital for Cripppled Children, 24 were found to have only minimal changes. The cases were grouped relative to the area of the femoral head involved, with 10 involving the anterior portion, seven the posteromedial, three the lateral, and four the central portion. Almost all hips lost some height as measured by the epiphysial index but all had good results by the Mose criteria irrespective of treatment. The anterior lesion is the same as that described by Catterall as Group 1. The three additional groups have a similar benign natural history but distinct radiographic features. The need for early recognition of these patterns is emphasised if unnecessary treatment is to be avoided. Possible correlations of these lesions with the segmental blood supply of the femoral head are proposed and an hypothesis relating the Catterall classifications to the blood supply is put forward

1. Orthopaedic treatment of joint deformities in thirteen patients with haemophilia is reviewed over a period of seven years. 2. Forms of treatment discussed include open operation, manipulation under general anaesthesia, continuous traction, splintage and physiotherapy. The amount of intravenous therapy required for each form of treatment is indicated. 3. In discussing prevention of joint deformity the histories of a further eighteen patients have been taken into account. It is concluded that initially painless haemarthroses provide the main threat to joint deformity in haemophilia. 4. The best preventive treatment is early immobilisation followed by prolonged splintage and physiotherapy; intravenous therapy with antihaemophilic factor plays a less important role here than in other forms of haemorrhage. 5. Evidence is presented that joint deformity in severe haemophilia can often be entirely avoided

1. The family history of, and associated congenital abnormalities in, patients with talipes equinovarus, talipes calcaneo-valgus and metatarsus varus living in Devonshire has been studied. 2. The chances of any individual having one of these deformities is approximately one per 1,000 in each case. 3. If one child in a family has the deformity, the chances of a second having it are one in thirty-five for talipes equinovarus and one in twenty for talipes calcaneo-valgus and metatarsus varus. 4. The male relatives of the female patients with talipes equinovarus are at particular risk. 5. It is suggested that the cause of club foot is partly genetic and partly environmental, from a factor acting on the foetus in the uterus. 6. The classification of associated congenital abnormalities leads to the suggestion that the genetic factor in talipes equinovarus and talipes calcaneo-valgus relates to defective formation of connective tissue

1. The detailed findings are presented of a woman aged fifty who had widely distributed ossifying skeletal tumours, the structure and form of which have been shown to be low-grade osteoblastic osteogenic sarcoma. The patient was treated with heavy doses of P. 32. , to which is attributed some clinical improvement, but which induced a fatal aplastic anaemia. 2. The study of the several tumours, together with the history, the radiographs and the post-mortem findings, suggests that the lesions are multifocal skeletal primary tumours rather than numerous osseous metastases secondary to a solitary new growth in any one bone. 3. The focal neoplastic lesion is discussed in the light of personal experience of other osteogenic sarcomata of low grade but of solitary origin, and of the multifocal form of bone sarcoma which may complicate Paget's osteitis deformans

Over a period of one year we treated nine fractures of the sesamoid bones of the hallux, five of which were in the medial sesamoid. All patients had symptoms on exercise, but only one had a recent history of injury. The mean age of the patients was 27 years (17 to 45) and there were six men. The mean duration of symptoms was nine months (1.5 to 48). The diagnosis was based on clinical and radiological investigations. We describe a new surgical technique for percutaneous screw fixation for these fractures using a Barouk screw. All the patients were assessed before and after surgery using the American Orthopaedic Foot and Ankle Society Hallux Score (AOFAS). There was a statistically significant improvement in the mean score from 46.9 to 80.7 (p = 0.0003) after fixation of the fracture with a rapid resolution of symptoms. All patients returned to their previous level of activity by three months. We believe that this relatively simple technique is an excellent method of treatment in appropriately selected patients
