EXCISION OF THE TRAPEZIUM FOR OSTEOARTHRITIS OF THE TRAPEZIO-METACARPAL JOINT
Authors: Gervis W. Harvey 
Published: February 2018

1. The technique of excision of the trapezium for osteoarthritis of the trapezio-metacarpal joint is described. 2. The results of eighteen operations in fifteen patients are analysed. 3. The operation is of value particularly when the arthritis is monarticular. Results have been less satisfactory when the affection of the joint is part of a generalised arthritis.
NEONATAL SCIATIC PALSY
Authors: Fahrni W. H. 
Published: February 2018

1. It is possible that neonatal sciatic palsy occurs more often than is suggested by perusal of the literature: paralysis of a foot may easily be overlooked in the new-born infant; it may be regarded as a temporary paresis due to mild birth trauma; or in later months it may be attributed to poliomyelitis. 2. Eleven cases of neonatal sciatic palsy are reported. Autopsy in one suggested that the paralysis was due to direct pressure on the sciatic nerve before birth. 3. A hypothesis is advanced by which to explain how pressure on the nerve trunk may arise in utero.
THE POPLITEUS MUSCLE AND THE LATERAL MENISCUS
Authors: Last R. J. 
Published: February 2018

1. The movements of flexion and extension at the knee joint take place above the menisci; the movements of rotation take place below the menisci. 2. The popliteus muscle consists of two halves, one being attached by tendon to the femur, the other by aponeurosis to the lateral meniscus. The action of the muscle is to rotate the knee and retract the posterior arch of the lateral meniscus. The flexing action of the muscle is quite negligible. 3. The effects of rotation of the knee joint on the two menisci are dissimilar. The medial meniscus is distorted during rotation; its horns move with the tibia, but the intervening arch moves with the femur, and the distortion renders it liable to injury during rotation. The lateral meniscus does not become distorted during rotation; it follows the lateral condyle of the femur by reason of the attachments of the ligaments of Humphry and Wrisberg and the popliteus muscle. It is thus relatively immune from injury daring rotation.
OPEN OPERATION FOR CONGENITAL DISLOCATION OF THE HIP
Authors: Platou Eivind 
Published: February 2018

1. The indications for open reduction in congenital dislocation of the hip are discussed. 2. The technique of the operation and the post-operative treatment are briefly described. 3. The results of the operation in fifty hips are presented. 4. The function and the radiographic appearances of the hip were usually good in the early years after open reduction, but there was a marked tendency to deterioration ten to thirteen years afterwards. 5. The indications for the shelf operation and for rotation osteotomy after open reduction are discussed.
PROGNOSIS IN TUBERCULOSIS OF THE HIP
Authors: DoBson J. 
Published: February 2018

1. Three hundred and twenty cases of tuberculosis of the hip joint have been analysed and the late results assessed three or more years after discharge from hospital. 2. The primary bone focus involved the acetabulum alone in 39Â·3 per cent; the acetabulum and femoral head in 34Â·1 per cent; the head of femur alone in 19Â·2 per cent, and the femoral neck alone in 7Â·4 per cent. In 101 cases widespread destruction of the joint had taken place by the time the patient first came under observation. 3. Premature epiphysial fusion round the knee joint of the affected side occurred in 23 per cent of all patients under the age of fifteen years. 4. When hip disease was complicated by multiple foci of active tuberculosis or by secondarily infected abscesses and sinuses, the prognosis was seriously worsened. 5. Significant late deformity occurred in 38Â·3 per cent of patients discharged with "sound" fibrous ankylosis, and in 60Â·5 per cent of those with an unstable fibrous ankylosis. 6. Of 187 patients observed for more than three years after discharge from hospital 174 returned to full activity, seven were partly incapacitated and six were totally incapacitated. 7. Analysis of the late results suggests that the prognosis is best when an adequate period of conservative treatment is followed by some form of arthrodesis operation.
CONGENITAL FUSION OF THE LUNATE AND TRIQUETRAL BONES IN THE SOUTH AFRICAN BANTU
Authors: Minnaar A. B. DeVilliers 
Published: February 2018

Twelve cases of congenital fusion of the lunate and triquetral bones have been found in South African Bantu patients. The fusion occurs in four types, an incomplete "pseudarthrosis," bony fusion with a dividing notch at one or both surfaces, or as a complete compound bone with or without other carpal anomalies. The suggestion favoured is that this fusion represents the persistence of a primitive characteristic in African (negro) peoples.
NAVICULO-CUNEIFORM FUSION IN THE TREATMENT OF FLAT FOOT
Authors: Jack Ewen A. 
Published: February 2018

1. Radiological investigation of cases of flat foot shows that they form three distinct anatomical types according to the precise level of the break in the arch. 2. When the break occurs at the naviculo-cuneiform joint alone, fusion of this joint in normal alignment should correct the deformity. 3. The results of operation on forty-six feet are analysed. Eighty-two per cent proved satisfactory. Failures are discussed and are considered avoidable by careful selection and operative technique.
THE MOVEMENTS OF BONES AND JOINTS
Authors: MacConaill M. A. 
Published: February 2018

1. The dynamics of synovial joints depends upon the geometry of the articular surfaces, which are always curved. 2. There are two types of articular curvature: ovoid (synclastic) and sellar (anticlastic). 3. The sellar type is mechanically more suited to movements in which sliding is combined with medial or lateral rotation (monodal conjunct rotation). 4. The movement of any hinge-joint is accompanied by a monodal conjunct rotation. This carries the moving part along a path that approximates (at least) to a path of minimal wear. The same is true of the paths of habitual effort-movement (ergodes) of other kinds of joint. 5. Evidence for the foregoing statements is drawn from both normal and abnormal joints, and a clinical application is suggested.
HYPEREXTENSION INJURY OF THE NECK WITH PARAPLEGIA
Authors: Berkin C. R. , Hirson Cedric 
Published: February 2018

1. The clinical and post-mortem findings are described of a patient who sustained a hyperextension injury of the neck with paraplegia. 2. There was no radiological evidence of fracture: osteoarthritis of the spine was present. 3. Evidence is presented that the cord was damaged from behind by the lamina of the vertebra below a tear in the anterior longitudinal ligament.
COMPLETE DISLOCATION OF THE ACROMIO-CLAVICULAR JOINT
Authors: Kennedy John C. , Cameron Howard 
Published: February 2018

1. Screw fixation of clavicle to coracoid process, with subsequent calcification and ossification along the conoid and trapezoid ligaments, creates an extra-articular fusion of the acromio-clavicular joint. 2. Though the follow-up is admittedly early, excellent results can be obtained in the young healthy adult. It is possible to return an athlete to competitive sports and a heavy labourer to full work in a surprisingly short time. 3. The operation is of doubtful value in older patients. 4. A precise operative technique is most important in producing a successful result. 5. Screw fixation introduces a new movement into the abduction mechanism of the shoulder: synchronous scapulo-clavicular rotation.
SPONDYLOLISTHESIS
Authors: Adkins E. W. O. 
Published: February 2018

1. A detailed analysis of the anatomy of spondylolisthesis reveals many causes of serious interference with the nerve roots. 2. These anatomical findings can be correlated with the symptoms. 3. In association with spondylolisthesis, cases of disc prolapse, tuberculosis, and a cauda equina lesion are described. 4. Adequate decompression of the affected nerve root is essential in all cases with sciatica. The operative procedure is described. 5. The problem of arthrodesis will be discussed fully in a separate paper.
OSTEOTOMY AS AN AID TO ARTHRODESIS OF THE HIP
Authors: Apley A. G. , Denham R. A. 
Published: February 2018

1. Arthrodesis of the hip is satisfactory provided a good range of knee flexion is preserved. 2. The hip is best arthrodesed in its deformed position, and the deformity corrected by a high femoral osteotomy. Knee range can readily be retained by treating the patient on traction for the first six weeks instead of using plaster. 3. Thirty-three arthrodeses were attempted without osteotomy. Only thirteen were satisfactory. Even our best method without osteotomy gave sound fusion in only seven out of ten cases. 4. In a series of twenty-three unselected cases in which osteotomy was performed in addition to other methods, fusion occurred in twenty-two.
THE RESULTS OF A REALIGNMENT OPERATION FOR RECURRENT DISLOCATION OF THE PATELLA
Authors: Harrison M. H. M. 
Published: February 2018

1. A realignment operation is described for the treatment of recurrent dislocation of the patella. 2. In twenty-three patients (twenty-seven knees) operation prevented further dislocation. The physical and functional condition of the knees two to twenty years after operation is described. 3. Patello-femoral osteoarthritis was not a clinical complication in any of these patients. This finding is discussed. 4. Genu recurvatum developed in four patients operated upon between the ages of ten and thirteen years. The cause of this deformity is discussed. It is concluded that the realignment operation should not be performed under the age of fourteen years. 5. In three patients operation failed to control the recurrent dislocation.
PRIMARY RETICULO-SARCOMA OF BONE
Authors: Magnus H. A. , Wood H. L.-C. 
Published: February 2018

1. Seven new cases of primary reticulo-sarcoma of bone are recorded, including one in which a full necropsy was carried out. 2. The literature of Ewing's tumour and reticulo-sarcoma of bone has been examined and the conclusion reached that the separation of these two tumours is an artificial one. 3. The investigation of our cases confirms this observation.
POLYARTERITIS NODOSA WITH NEW BONE FORMATION
Authors: Saville Paul D. 
Published: February 2018

1. A case of polyarteritis nodosa is reported, the presenting manifestation of which was subperiosteal new bone formation in both legs. 2. The effect of cortisone on the symptoms is recorded. 3. The histology is reported after biopsy of bone and adjacent tissue. 4. Skeletal involvement in polyarteritis nodosa is believed to be hitherto unrecorded.
CONGENITAL VERTICAL TALUS
Authors: Osmond-Clarke H. 
Published: February 2018

1. Attention is drawn to that type of rigid congenital flat foot in which the talus lies vertically instead of horizontally. 2. This deformity is rare, but if not treated successfully leads to an ugly, painful foot in adolescence. 3. The experience of five patients forms the basis of the present preliminary account. One adolescent and two young children under the age of five were treated unsuccessfully by both conservative and operative measures. More recently in two children with bilateral deformity open operation has been successful in restoring the shape of the foot. 4. The operation is essentially a reduction of a subluxation at the talo-navicular and subtalar joints. It entails freeing the head of the talus sufficiently to allow it to be lifted dorsally and laterally. The talus is then anchored in position by transplanting the distal end of the peroneus brevis tendon through the neck of the bone.
FEMORAL OSTEOTOMY IN EXTRA-ARTICULAR ARTHRODESIS OF THE TUBERCULOUS HIP
Authors: Cholmeley J. A. 
Published: February 2018

1. One hundred and forty-two cases of extra-articular arthrodesis of quiescent tuberculous hips with fibrous ankylosis have been reviewed. 2. The methods used were the ilio-femoral graft with and without osteotomy, and the ischio-femoral graft by the Brittain or Foley technique. 3. Success occurs more frequently when the grafting operation is combined with or followed by a femoral osteotomy. 4. It is suggested that this success is due largely to the increased immobilisation afforded by the osteotomy. 5. It appears that equally good results can be obtained with either an ilio-femoral or an ischio-femoral graft in these cases provided that an upper femoral osteotomy is also carried out, preferably at or soon after the grafting operation. 6. An upper femoral osteotomy will frequently convert an unsuccessful extra-articular hip graft into a successful one without further grafting.
THE RESULTS OF LUMBO-SACRAL FUSION FOR LOW BACK PAIN
Authors: Shaw E. G. , Taylor J. G. 
Published: February 2018

1. In this series of posterior onlay grafting with fresh autogenous bone and without internal fixation, in the treatment of non-infective structural lesions in the lumbo-sacral area, 71 per cent of the patients were relieved of their symptoms, but bony fusion was obtained in only 60 per cent. 2. It is probable that with this technique twelve weeks' immobilisation in a plaster bed is required. 3. Some failures are ascribed to the use of an insufficient quantity of bone or to poor apposition of the graft to its bed. 4. It is evident that the more vertebrae one attempts to fuse the more difficult it is to succeed. When the diseased area is successfully fused but an unnecessarily long graft has been used, a pseudarthrosis above the level of the pre-operative pathology may be the cause of persisting backache. For these reasons we believe that one should not attempt to graft more vertebrae than is necessary to stabilise the local lesion. 5. The complication rate, particularly from deep vein thrombosis, was high. This major complication could perhaps be overcome by using banked bone. 6. The indications for the operation are assessed as follows. It should be done for low back pain only when there is a definite diagnosis and a limited extent of structural pathology; one can then expect excellent results when successful fusion is achieved and also an appreciably high proportion of satisfied patients even when bony fusion has not been obtained, presumably because there is a fibrous union strong enough to stabilise the affected spine. It is inadvisable to undertake lumbar-lumbo-sacral fusion for intervertebral disc degeneration when there are more than three adjacent vertebrae involved, and in any case operation should be confined to the indicated extent.
PARALYTIC SCOLIOSIS
Authors: James J. I.P. 
Published: February 2018

1. The prognosis of paralytic scoliosis has been studied by defining curve patterns and establishing the natural development as seen in fully grown patients who have not had surgical correction. 2. The prognosis, unlike that in idiopathic scoliosis, is related to the age of onset of the curvature and the degree of muscle imbalance rather than the site of the primary curve. 3. Paralysis of limb muscles is shown to be unrelated to the development of scoliosis. The intercostal muscles and the lateral abdominal flexors produce scoliosis when weaker on the convex side of the curve. Gravity and the other trunk muscles certainly play a part in the development of lumbar curves but their importance is difficult to assess.
FRACTURES OF THE LATERAL TIBIAL CONDYLE TREATED BY SKELETAL TRACTION AND EARLY MOBILISATION
Authors: Apley A. Graham 
Published: February 2018

1. The term "bumper fracture" is colourful but usually inaccurate. The injury is a valgus split or crush. 2. A series of sixty bumper fractures is reported: forty-eight were treated without operation or plaster. 3. Twenty-seven of the forty-eight patients treated without splintage have been followed up for more than five years, and seventeen of these for more than ten years. 4. The results are satisfactory and there is no evidence that there is any late deterioration of the joint. 5. It is suggested that bumper fractures should be treated without operation and without fixation in plaster.
ANKLE AND SUBTALAR FUSION BY A TRANSARTICULAR GRAFT
Authors: Bingold A. C. 
Published: February 2018

1. Three pantalar, one ankle and subtalar, and three ankle arthrodeses have been performed by a technique, the essential step of which is the insertion of a transarticular graft from below. Union has occurred in four to five months. 2. A method is described of determining the degree of equinus before the operation and securing it during the operation. 3. Pantalar fusion by this technique compares favourably with the methods described so far.
DYSTROPHIA MYOTONICA ASSOCIATED WITH FAMILIAL PAGET'S DISEASE (OSTEITIS DEFORMANS) WITH SARCOMATA
Authors: Caughey J. E. , Gwynne J. F. , Jefferson N. R. 
Published: February 2018

1. A report is given of a family suffering from dystrophia myotonica and familial Pagetâs disease of bone. 2. Radiological changes in the skull occur in both disorders, which are quite dissimilar. Thickening of the calvarium, however, may be common to both. 3. The serum alkaline phosphatase is high in Paget's disease and normal in dystrophia myotonica. 4. In one patient the Paget's disease was complicated by the development of multiple sarcomata. Sarcomatous involvement of the vertebral column, observed in one of the cases, has not been recorded before.
THE NORMAL VASCULAR ANATOMY OF THE HUMAN FEMORAL HEAD DURING GROWTH
Authors: Trueta Joseph 
Published: February 2018

1. The results of a study of the characteristics of the vessels found in forty-six human femoral heads during the growth period are described. 2. Of the three different sources of blood entering the human adult femoral head it was found that from birth to about three to four years the vessels of the ligamentum teres do not contribute to the nourishment of the head. 3. After the fourth year the metaphysial vessels decrease in importance until they finally disappear, leaving the head with only one source of blood through the lateral epiphysial vessels; the ligamentum teres is not yet contributing to the circulation of the head. 4. After about eight or nine years it was found that the vessels of the ligamentum teres contribute to the blood supply of the head while the metaphysial blood flow is still arrested. 5. Finally, at puberty, after a period of activity of the metaphysial vessels, epiphysial fusion takes place, bringing together the three sources of blood characteristic of the adult.
UNREDUCED ANTERIOR DISLOCATION OF THE HIP
Authors: Hamada Gawad 
Published: February 2018

1. Un reduced anterior dislocation of the hip is very uncommon. Four cases are reported. 2. The aim of treatment is to correct the deformity, to improve the gait and to produce pelvic stability. 3. Osteotomy of the femur at the trochanteric level is the simplest corrective operation and will greatly improve the function of the limb.
FLEXION-COMPRESSION INJURY OF THE STERNUM
Authors: Fowler A. W. 
Published: February 2018

1. Injuries of the sternum from flexion-compression violence are described and contrasted with injuries from direct violence. The characteristic feature of flexion-compression injuries is a dislocation or fracture at or near the manubrio-sternal joint with backward displacement of the manubrium. 2. Treatment is outlined, with special reference to the indications for open reduction and wire fixation. 3. The mechanism of flexion-compression injuries of the sternum is discussed. The opinion is expressed that most of the force is transmitted to the sternum by the ribsâespecially the upper ribs.
THE HYDRATION OF THE NUCLEUS PULPOSUS AND ITS RELATION TO INTERVERTEBRAL DISC DERANGEMENT
Authors: Hendry Neil G. C. 
Published: February 2018

1. Eighteen normal discs from cadavers and seventy-five specimens of abnormal disc material obtained at laminectomy have been compared. 2. Imbibition pressure, and not osmotic pressure, is the important factor in maintaining hydration of the nucleus, and the comparison has been based on this finding. The terms "free imbibition index" and "effective imbibition index" are suggested as being readily determinable means of expressing the functional efficiency of a nucleus. 3. A reduction in imbibition pressure was a constant feature of the specimens obtained at operation. No evidence was found to support the theory that hyper-hydration or engorgement of the nucleus plays a part in disc protrusion. A reduction in imbibition pressure can, however, be expected in itself, by a combination of mechanical and hydrostatic effects, to cause disc derangements. 4. The reduced imbibition pressure of abnormal discs is related to abnormal loss of, or deterioration in, the protein/polysaccharide of the nucleus. The premature onset of, or some disturbance in, the normal ageing process is a prime cause of mechanical derangement of the disc.
TUBERCULOSIS OF THE PUBIS
Authors: Nicholson O. R. 
Published: February 2018

1. Eleven cases of tuberculosis of the pubis are described. 2. The disease is often of insidious onset, and symptoms vary from vague discomfort to incapacitating pain in the region of the symphysis and the groin. 3. Abscess formation is common and was present in nine of the eleven patients when they first attended. 4. The lesion has a good prognosis and responds well to simple curettage. 5. In this series operation, without bone grafting, has not been followed by pelvic instability or back pain.
FAMILIAL METAPHYSIAL DYSPLASIA
Authors: David J. E.A. , Palmer P. E.S. 
Published: February 2018

1. Familial metaphysial dysplasia occurring in two families is recorded. 2. One case with unusual skull changes and webbing of the digits is described in detail. 3. The similarity between the shape of the bones in familial metaphysial dysplasia and other bone disease is discussed.
CORACOID TRANSPLANTATION FOR RECURRING DISLOCATION OF THE SHOULDER
Authors: Helfet Arthur J. 
Published: February 2018

1. Coracoid transplantation for recurring dislocation of the shoulder is described. 2. In my experience of over thirty cases only once has true dislocation recurred after this operation. Recurrence was due to avulsion of the bone block. 3. Failure to repair the original detachment of the glenoid labrum is a frequent cause of recurrence of dislocation of the shoulder. An explanation is offered for this failure; namely that the injured labrum adheres to the deep surface of the subscapularis muscle instead of reattaching itself to bone. This reinforces Watson-Jones's advice that the original dislocation should be treated by complete immobilisation in full medial rotation for three weeks.
RECURRENT POSTERIOR DISLOCATION OF THE SHOULDER
Authors: Jones Victor 
Published: February 2018

1. A case of recurrent posterior subluxation of the shoulder is described. After failure of a soft-tissue repair, a posterior bone block operation was performed. 2. The distinction between traumatic dislocations with tearing of the capsule or of the glenoid labrum, and habitual luxations from laxity of the capsule, is emphasised. Although the anterior rim of the glenoid was detached in this case, it is considered to fall into the latter category. 3. A posterior bone block provides a simple and efficient form of repair in this type of case. It is free from the disadvantage of causing limitation of rotation at the shoulder joint; it employs a principle which might well merit more application than at present in the repair of anterior dislocations.
