1 . A ten-year study of fifty-four operations for transplantation of the hamstring muscles in thirty-one spastic patients has been made. 2. Twenty-one patients were improved after operation, six were not improved, and in four the duration of follow-up was too short for proper assessment. One patient died from other causes. 3. Greatest benefit was not obtained until one year after operation. 4. The results varied considerably in different grades of spastic patient. Important factors affecting the results were age, sex, personality, balance and function of arm and hip.
Both osteochondritis dissecans and coxa plana are diseases with identical pathological changes, namely avascular necrosis. Although the etiology is not known in either case, it seems likely that when the etiological factors are fully determined they will prove to be applicable to either condition. The relative importance of each etiological factor in the multiple pathogenesis of these two conditions is almost certainly different in each disease process, and probably in each individual case. Present day concepts suggest that there is an underlying constitutional disturbance, which is associated with other factors (of which trauma is almost universally accepted as being one; perhaps the only one), to predispose the individual to these conditions. It is hoped that further studies along these lines will not only help to provide a better understanding of the two conditions mentioned above, but will also be of value in the appreciation of the pathogenesis and etiology of a large number of disturbances including such varied conditions as dysplasia epiphysialis multiplex congenita, cretinoid dysgenesis of the capital femoral epiphysis, adolescent coxa vara, transient synovitis of the hip, and the recently discussed (Merle d'Aubigné 1964) idiopathic avascular necrosis of the femoral head in adults. That there is an etiological relationship between osteochondritis dissecans and coxa plana seems clear, but much more work is required before we will have at
1 . Twenty-one cases of poliomyelitis and twenty cases of brachial plexus injury in which muscle transplantations had been performed to restore elbow flexion have been reviewed. The average follow-up period was four and a half years. 2. The results were graded objectively and subjectively. They were better when passive extension of the elbow was limited; such limitation always occurs after Steindler's operation, but infrequently after pectoral transplantation. 3. The results of pectoral transplantation are good when there is no significant shoulder paralysis; if there is shoulder weakness arthrodesis of the joint may be required to control medial rotation and adduction of the shoulder on flexion of the elbow. In brachial plexus lesions the results of pectoral transplantation may be marred by simultaneous contraction of the triceps. This can be overcome by transplanting triceps into the flexor apparatus. Triceps transplantation is rarely indicated because loss of active extension of the elbow is a grave disability. 4. Subjective results tended to be worse than objective results in brachial plexus lesions because impairment of sensibility in the
Most brachial plexus palsies are due to trauma, often resulting from motorcycle accidents. When nerve repair and physiotherapy are unsuccessful, muscle transfer may be considered. Paralysis of the deltoid and supraspinatus muscles can be addressed by transfer of the trapezius. Between March 1994 and June 1997 we treated 38 patients with brachial plexus palsy by trapezius transfer and reviewed 31 of these (7 women, 24 men) after a mean follow-up of 23.8 months (12 to 39), reporting the clinical and radiological results and subjective assessment. The mean age of the patients was 29 years (18 to 46). The operations had been performed according to the method of Saha described in 1967, involving transfer of the acromion with the insertion of the trapezius to the proximal humerus, and immobilisation in an abduction support for six weeks. Rehabilitation started on the first postoperative day with active exercises for the elbow,
Since this paper was submitted for publication three additional reports have appeared, two of which represent typical examples of the syndrome. Husson and Parkman (1961) reported the case of a female infant dying at the age of four months with chondroectodermal dysplasia, obliteration of the upper labiogingival sulcus, and congenital heart disease. The heart lesions included anomalous pulmonary venous return, single atrium and a persistent left superior vena cava. There was no known consanguinity. In reviewing the cardiac lesions described in chondroectodermal dysplasia they include another case with anomalous pulmonary venous return described by Darling, Rothney and Craig (1957), which also showed chondroectodermal dysplasia and polydactyly, though details of the extracardiac malformations are not given. Nabrady (1961) described a four-year-old Hungarian girl with ectodermal defects involving the teeth and nails but not the hair, polydactyly, distal shortening of the extremities producing dwarfing, and typical radiological appearances of the long bones. There was presumptive evidence of a septal defect of the heart. There was no consanguinity, but the mother was considered to show a "forme fruste" of the condition. A necropsy report by Meitner (1961) of a newly born premature infant with multiple congenital malformations of organs of ectodermal, mesodermal and endodermal origin is of interest because these malformations included extreme polydactyly of
We describe a method of partial limb salvage for the treatment of large primary malignant tumours of the arm. The tumour-bearing area is resected as a cylindrical segment and the distal arm is then replanted with the necessary shortening. The method is suitable for stage-IIB tumours with or without neurovascular involvement which, because of their extent, could otherwise be adequately treated only by amputation. From 1987 to 1992 we used this method in 12 patients with primary malignant bone or soft-tissue sarcomas. Wide resection margins were achieved in all, but six patients died from their disease at a mean of 21.5 months (6 to 48), none with any local recurrence. Five patients have no evidence of disease at a mean follow-up period of 52.2 months (22 to 78), and one was lost to follow-up at 48 months postoperatively when there was no evidence of disease. The results of the functional evaluation of ten patients with a follow-up of over ten months were excellent in one, good in six and fair in three, by the criteria of Enneking (1987). Recovery after nerve reconstruction was satisfactory in all cases with sensation S3 or higher and motor function M2+ or higher. Detailed evaluation of
The aim of this study was to utilize a national paediatric inpatient database to determine whether obesity influences the operative management and inpatient outcomes of paediatric limb fractures. The Kids’ Inpatient Database (KID) was used to evaluate children between birth and 17 years of age, from 1997 and 2012, who had undergone open and closed treatment of humeral, radial and ulna, femoral, tibial, and ankle fractures. Demographics, hospital charges, lengths of stay (LOS), and complications were analyzed.Aims
Patients and Methods
Using 90% of final height as a benchmark, we sought to develop
a quick, quantitative and reproducible method of estimating skeletal
maturity based on topographical changes in the distal femoral physis. Serial radiographs of the distal femoral physis three years prior
to, during, and two years following the chronological age associated
with 90% of final height were analyzed in 81 healthy children. The
distance from the tip of the central peak of the distal femoral
physis to a line drawn across the physis was normalized to the physeal width.Aims
Patients and Methods
The purpose of this paper has been to stimulate interest in amputation surgery, prosthetics and orthotics, and to illustrate the excellent work done in only some of the centres within the British Isles and to enlist the assistance of all orthopaedic surgeons in improving the orthotic equipment of their patients. We also need the interest and the practical involvement of one orthopaedic surgeon in amputation work and prosthetics in almost every large hospital, particularly in the centres where it is to be expected that limb-fitting units will be installed and fully integrated within the hospital service. It is necessary to say "almost every large hospital", because in some the vascular surgeon will lead the amputation and prosthetic team. This is a worthwhile special interest for the orthopaedic surgeon. The need presents itself not only for the geriatric patient with limb ischaemia and for those who lose a limb from trauma, but also for the quite considerable number of children who are congenitally without a limb or part of a limb. Orthopaedic surgery embraces a wide field, and in the larger centres the best work will result from a voluntary restriction in the field of operation of individual surgeons, many being involved in trauma and fractures, all being involved in adult orthopaedic surgery, some with a special interest and considerable time in children's orthopaedic surgery, or
1. The long-term results of 740 European patients suffering from spinal tuberculosis and treated without and with specific anti-tuberculous drugs have been surveyed. 2. The results of treatment by conservative methods and by conventional surgical methods have been compared in the two periods. The attainment of spinal stability as judged by serial examination of radiographs was the main criterion in assessing healing. 3. Although the results of conventional treatment have improved since the advent of chemotherapy, the credit is mainly due to the influence of more frequently and more expertly applied operations. 4. With chemotherapy the well tried medical and surgical procedures produce stable spines in three-quarters of cases. With early operation on the lesion the results are better and more quickly obtained. Of eighty spines on which focal surgery was performed during the past twelve years before the lesions had become extensive, seventy-seven (9·62 per cent) healed by bone. The average duration of hospitalisation after such operation was four and a half months. No patient has had to be readmitted. 5. The difficulties and possible dangers of these methods must be emphasised. The operations are difficult and dangerous when the lesions have been allowed to get out of

The purpose of this multicentre observational study was to investigate the association between intraoperative component positioning and soft-tissue balancing on short-term clinical outcomes in patients undergoing robotic-arm assisted unicompartmental knee arthroplasty (UKA). Between 2013 and 2016, 363 patients (395 knees) underwent robotic-arm assisted UKAs at two centres. Pre- and postoperatively, patients were administered Knee Injury and Osteoarthritis Score (KOOS) and Forgotten Joint Score-12 (FJS-12). Results were stratified as “good” and “bad” if KOOS/FJS-12 were more than or equal to 80. Intraoperative, post-implantation robotic data relative to CT-based components placement were collected and classified. Postoperative complications were recorded.Aims
Patients and Methods
The Attune total knee arthroplasty (TKA) has been used in over 600 000 patients worldwide. Registry data show good clinical outcome; however, concerns over the cement-tibial interface have been reported. We used retrieval analysis to give further insight into this controversial topic. We examined 12 titanium (Ti) PFC Sigma implants, eight cobalt-chromium (CoCr) PFC Sigma implants, eight cobalt-chromium PFC Sigma rotating platform (RP) implants, and 11 Attune implants. We used a peer-reviewed digital imaging method to quantify the amount of cement attached to the backside of each tibial tray. We then measured: 1) the size of tibial tray thickness, tray projections, peripheral lips, and undercuts; and 2) surface roughness (Ra) on the backside and keel of the trays. Statistical analyses were performed to investigate differences between the two designs.Objectives
Methods
The aim of this study was to determine the diagnostic utility of histological analysis in spinal biopsies for spondylodiscitis (SD). Clinical features, radiology, results of microbiology, histology, and laboratory investigations in 50 suspected SD patients were evaluated. In 29 patients, the final (i.e. treatment-based) diagnosis was pyogenic SD; in seven patients, the final diagnosis was mycobacterial SD. In pyogenic SD, the neutrophil polymorph (NP) infiltrate was scored semi-quantitatively by determining the mean number of NPs per (×400) high-power field (HPF).Aims
