We present our experience with correction of Madelung’s deformity by the Ilizarov technique. Seven patients (eight deformities) were treated by osteotomy of the radius with subsequent lengthening and angular correction. They were reviewed at a mean of 30 months (1.5 to 5.5 years). At the time of operation their mean age was 19 years (9 to 44). At follow-up all were free from pain and supination had improved by a mean of 34° and pronation by 9°. Flexion had increased in most cases with a median increase of 15°, but only one patient gained further extension. Radial and ulnar deviation were increased by a mean of 6° and 9°, respectively. Radiographic measurements showed that the mean volar angulation had been reduced from 25° to 11°, ulnar inclination from 45° to 30° and carpal malalignment (volar translation) from 7 to 2 mm. The mean lengthening of the radius was 12 mm (6 to 25). All the patients were satisfied with the functional and cosmetic results

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

Between 1993 and 1999, we treated ten patients with comminuted fractures of the olecranon by multiple tension-band wiring and a graft from the iliac crest. Their mean age was 35 years (19 to 56). The mean follow-up was for 28.5 months (15 to 46) and the mean time to union of the fractures was four months (3 to 7). No patient reported difficulties with activities of daily living or symptoms of instability of the elbow. The mean flexion was to 135° (125 to 145) with a mean flexion contracture of 15° (10 to 30). The mean pronation was 70° (60 to 80) and mean supination 79° (70 to 90). Only three patients had mild pain and loss of strength. Five patients had excellent and five good results with a mean Broberg and Morrey index score of 94.5 points (84 to 100). Our results compare favourably with those previously reported and the technique is thought to be a practical alternative to plate fixation in fractures with extreme comminution

From 1990 to 1993 we treated 22 consecutive patients who had progressive spinal kyphosis due to ankylosing spondylitis by a closing-wedge posterior vertebral osteotomy with partial corporectomy of L4 and transpedicular fixation. The average correction was 32 degrees (24 to 52) with a mean loss of correction after operation of 2.7 degrees (0 to 13). The average operating time was 185 minutes (135 to 240) and blood loss was 2500 ml (1200 to 5000). The osteotomy corrected all patients sufficiently to allow them to see ahead and their posture was improved. There were no fatal complications, but in two cases there was failure of the instrumentation and one patient needed reoperation for nerve compression. Two deep wound infections required removal of the implant and six patients had superficial skin infections under the plaster. The use of a circoelectric bed and intermittent prone lying eliminated this problem

We have determined the natural history of hip development in 42 patients with multiple epiphyseal dysplasia (MED). Premature osteoarthritis was a frequent outcome and was almost inevitable before the age of 30 years in those with incongruent hips. There were two types of immature hips: type I, the more severe form, had a fragmented and flattened ossific nucleus and acetabular dysplasia, was misshapen at skeletal maturity and osteoarthritic by 30 years of age; the milder type II hip had a small, rounded, uniformly ossified nucleus and a more normal acetabulum. Type II hips were well formed at maturity and were less prone to premature osteoarthritis. Considerable variations were noted in the manifestations of MED between families but not within families. The prognosis of a child's hip could be predicted; in sporadic cases from the type of immature hip, and in familial cases by also taking into account the outcome of affected relatives

1. Thirty-five children suffering from a mild illness with narrowing of an intervertebral disc have been studied. 2. Backache was the presenting symptom in only a small proportion of children, vague aching in the legs being almost as common at the onset. 3. Stiffness of the affected part of the spine is often present, but there may be no abnormal signs in the back. 4. Radiographs reveal a narrowed disc space with adjacent bony changes. There is usually progressive narrowing of the disc space which may go on to fusion of the affected vertebrae. Less commonly there is reconstitution of the affected disc. 5. The symptoms and signs quickly subside with immobilisation in recumbency and this treatment should be continued until the blood sedimentation rate returns to normal. 6. Adults who have suffered from discitis in childhood are probably more prone to develop backache. 7. The etiology remains uncertain

1. Published comparisons of the results of conservative and operative treatment of trochanteric fractures have been fallacious because the groups have not been strictly comparable and because all deaths during convalescence have not been included. 2. In a series of cases studied at Oxford, comparable groups have been secured by allotting alternate cases to each group. All deaths within three months of injury have been included, whether occurring in hospital or elsewhere. 3. There was no great difference in mortality or in functional results between the two groups. One type of trochanteric fracture gives poor results whatever the method of treatment. 4. The series is too small for statistical conclusions, but the results suggest that the only advantages of operative treatment are greater economy of hospital beds, and increased comfort and mobility for the patient. The latter factor is important in frail patients, who are believed to be less prone to develop non-fatal complications if treated by operation than if treated conservatively

Aims

Optimal exposure through the direct anterior approach (DAA) for total hip arthroplasty (THA) conducted on a regular operating theatre table is achieved with a standardized capsular releasing sequence in which the anterior capsule can be preserved or resected. We hypothesized that clinical outcomes and implant positioning would not be different in case a capsular sparing (CS) technique would be compared to capsular resection (CR).

We studied radiographs of the wrists of 120 healthy volunteers in order to determine the normal range of ulnar variance. They had been taken in various positions under both unloaded (static) and loaded (dynamic) conditions. Pronation posteroanterior, supination anteroposterior and neutral posteroanterior views were taken of each wrist before and during a maximum grip under identical conditions. The mean normal ulnar variance in neutral rotation was +0.74 ± 1.46 mm, a value which was significantly lower in males than in females. We found negative variance in 26% of cases. We measured maximum ulnar variance (UV. max,. +1.52 ± 1.56 mm) when gripping in pronation and minimum ulnar variance (UV. min,. +0.19 ± 1.43 mm) when relaxed in supination. We subtracted UV. min. from UV. max. to calculate a mean maximum dynamic change in ulnar variance of 1.34 ± 0.53 mm. We consider this database of normal values to be useful for both the diagnosis and treatment of conditions related to discrepancy in radio-ulnar length and for clinical research

Aims

Our purpose was to describe an unusual series of 21 patients with fungal osteomyelitis after an anterior cruciate ligament reconstruction (ACL-R).

Post-traumatic elbow stiffness is a disabling condition that remains challenging for upper limb surgeons. Open elbow arthrolysis is commonly used for the treatment of stiff elbow when conservative therapy has failed. Multiple questions commonly arise from surgeons who deal with this disease. These include whether the patient has post-traumatic stiff elbow, how to evaluate the problem, when surgery is appropriate, how to perform an excellent arthrolysis, what the optimal postoperative rehabilitation is, and how to prevent or reduce the incidence of complications. Following these questions, this review provides an update and overview of post-traumatic elbow stiffness with respect to the diagnosis, preoperative evaluation, arthrolysis strategies, postoperative rehabilitation, and prevention of complications, aiming to provide a complete diagnosis and treatment path.

Between 1993 and 1996, we undertook 35 Kudo 5 total elbow replacements in a consecutive series of 31 rheumatoid patients. A total of 25 patients (29 procedures) was evaluated at a mean follow-up of six years (5 to 7.5) using the Mayo Clinic performance index. In addition, all patients were assessed for loosening using standard anteroposterior and lateral radiographs. At review, 19 elbows (65%) had either no pain or mild pain, ten (35%) had moderate pain and none had severe pain. The mean arc of flexion/extension was 94° (35 to 130) and supination/pronation was 128° (30 to 165). A fracture of the medial epicondyle occurred during surgery in one patient. This was successfully treated with a single AO screw and a standard Kudo 5 implant was inserted. Postoperatively, there were no infections. One patient had a dislocation which was treated by closed reduction and five had neurapraxia of the ulnar nerve. Radiologically, there was no evidence of loosening of the humeral component, but two ulnar components had progressive radiolucent lines suggestive of loosening. Two other ulnar components had incomplete and non-progressive radiolucent lines. With definite radiological loosening as the endpoint, the probability of survival of the Kudo 5 prosthesis at five years using the Kaplan-Meier method was 89%

1. The operation of spinal fusion combined with Harrington rod instrumentation is often accompanied by severe blood loss. Factors affecting the degree of blood loss are discussed with emphasis on the adverse effects of partial or complete obstruction of the inferior vena cava during operation. 2. A new scoliosis operating frame is described which is designed to encourage normal venous return during spinal fusion with the patient prone. In addition, it stabilises the patient during the procedure. 3. A standard anaesthetic technique and method of supporting the patient have been used in forty major corrective operations in thirty-eight consecutive cases of scoliosis in the past nine months. The measured blood loss at operation encountered in this series compares favourably with the quantities lost in a previously reported series of cases in which alternative methods of anaesthesia and of support for the patients were used. 4. All operations in both series were performed by the same surgeon (J. E. H.). Although further experience with the surgical technique has helped in reducing the blood loss in the later series, the same basic method of exposure and performance of the instrumentation and fusion has been used in all cases

Aims

The aim of this study was to investigate whether including the stages of ulnar physeal closure in Sanders stage 7 aids in a more accurate assessment for brace weaning in patients with adolescent idiopathic scoliosis (AIS).

Between 1995 and 2000, 19 consecutive patients with fractures of the distal humerus were treated by primary total elbow replacement using the Coonrad-Morrey prosthesis. No patient had inflammatory or degenerative arthritis of the elbow. The mean age at the time of injury was 73 years (61 to 95). According to the AO classification, 11 patients had suffered a C3 injury, two a B3 and two an A3. One fracture was unclassified. Two patients died from unrelated causes and one was unable to be assessed because of concurrent illness. The mean time to follow-up was three years (1 to 5.5). At follow-up 11 patients (68%) reported no pain, four (25%) had mild pain with activity and one had mild pain at rest. The mean flexion arc was 24° to 125°. The mean supination was 90° (70 to 100) and pronation 70° (50 to 110). No elbow was unstable. The mean Disabilities of the Arm, Shoulder and Hand score was 23 (0.92 to 63.3) and the mean Mayo elbow performance score was 93 (80 to 100). Of the 16 patients, 15 were satisfied with the outcome. Radiological evaluation revealed only one patient with a radiolucent line at the cement-bone interface. It was between 1 and 2 mm in length, was present on the initial postoperative radiograph and was non-progressive at the time of follow-up. Primary total elbow arthroplasty is an acceptable option for the management of comminuted fractures of the distal humerus in elderly patients when the configuration of the fracture and the quality of the bone make reconstruction difficult

Aims

The effect of the gut microbiota (GM) and its metabolite on bone health is termed the gut-bone axis. Multiple studies have elucidated the mechanisms but findings vary greatly. A systematic review was performed to analyze current animal models and explore the effect of GM on bone.

Aims

As the first wave of the COVID-19 pandemic began to dip, restarting elective orthopaedics became a challenge. Protocols including surgery at ‘green’ sites, self-isolation for 14 days, and COVID-19 testing were developed to minimize the risk of transmission. In this study, we look at risk effects of 14-day self-isolation on the incidence of venous thromboembolism (VTE) in our green site hospital among patients undergoing total joint replacement (TJR).

Aims

Ageing-related incompetence becomes a major hurdle for the clinical translation of adult stem cells in the treatment of osteoarthritis (OA). This study aims to investigate the effect of stepwise preconditioning on cellular behaviours in human mesenchymal stem cells (hMSCs) from ageing patients, and to verify their therapeutic effect in an OA animal model.
