EXISTENCE AND INCIDENCE OF OSTEOID IN OSTEOARTHRITIC FEMORAL HEADS
Authors: Batra H. C. , Charnley J. 
Published: February 2018

1. Specimens are described in which osteoid was seen in undecalcified bone sections prepared from a number of osteoarthritic femoral heads. 2. It was localised mostly in the pressure segments. 3. The reason for the presence of this osteoid is not well understood and the possibilities of local histochemical changes and/or cellular metaplasia are discussed.
SUBACUTE HAEMATOGENOUS OSTEOMYELITIS
Authors: King D. M. , Mayo K. M. 
Published: February 2018

1. Sixty-seven patients with subacute haematogenous osteomyelitis are reported. 2. The benign nature of the disease is noted. 3. The clinical types of infection are reported, with regard to the site of the lesion. 4. The treatment is described.
SYME'S AMPUTATION
Authors: Baker G. C. W. , Stableforth P. G. 
Published: February 2018

1. All traceable Syme amputees attending the Edinburgh limb centre have been seen and reviewed. They number sixty-seven. Forty had amputations twenty-five or more years before. 2. There are seventy-one surviving stumps. One has failed. 3. Records of all the below-knee amputees reveal five further failures of Syme stumps. The causes of failure are discussed. 4. Problems in the Syme stump are rare after the first year. The early difficulties are discussed. 5. We conclude that a patient with Syme's amputation can expect his stump to give a lifetime of service.
MAJOR INJURIES OF THE TALUS
Authors: Kenwright J. , Taylor R. G. 
Published: February 2018

1. Fifty-eight major injuries in the region of the talus were reviewed regarding treatment, incidence of complications and long-term results. 2. The prognosis for simple fractures of the head, neck or body was good, as was that for dislocations of the midtarsal and peritalar joints. 3. The prognosis for fracture-dislocations of the neck and body was better than has been frequently reported. It was related to the degree of initial trauma. A good result occurs only if accurate reduction is effected and maintained. Fixation with a Kirschner wire is a useful method of maintaining the reduction after unstable fracture-dislocations. 4. Avascular necrosis occurred only in the more severe injuries and its incidence was related to the degree of initial displacement. The late results were better than have been previously described. The condition is best treated conservatively by protection from weight-bearing until revascularisation is well advanced. 5. A case with an unusual pattern of fracture of the neck of the talus is described following a plantar-flexion inversion injury.
SOLITARY EOSINOPHILIC GRANULOMA IN BONE
Authors: Fowles J. V. , Bobechko W. P. 
Published: February 2018

1. Forty patients with solitary eosinophilic granuloma of bone from the Hospital for Sick Children, Toronto, have been reviewed. They had clinical and laboratory findings similar to those reported by others except for the erythrocyte sedimentation rate, which was raised in nearly half the patients tested. 2. Radiographs in all cases showed the lesion to be osteolytic. In the skull and cervical spine there was no bony reaction ; in the thoracic and lumbar spine the typical picture of Calvés disease was produced; in long bones the cortex commonly showed endosteal erosion and periosteal reaction. 3. In one patient the lesion progressed so rapidly that the body of a cervical vertebra was destroyed within ten days. 4. The differential diagnosis includes sarcoma. Biopsy is essential. 5. All the patients improved regardless of the treatment they received. Complications were due either to the site of the lesion or to its treatment. 6. Expansion of the lesion after biopsy indicates a more widespread manifestation of histiocytosis X.
SURGICAL RELIEF FOR SPASTIC TETRAPLEGIA DUE TO CERVICAL CORD COMPRESSION
Authors: Fuller David J. 
Published: February 2018

1. A case of cervical cord compression due to a congenital anomaly of the arch of the axis, treated successfully by decompressive laminectomy twenty-six years after the onset of symptoms, is described. 2. The significance of bony abnormalities of the cervical spine as a treatable cause of spastic tetraparesis is stressed.
ARTHROGRYPOSIS MULTIPLEX CONGENITA
Authors: Gibson D. A. , Urs N. D. K. 
Published: February 2018

1. Eighty-two patients out of 114 with arthrogryposis seen at the Hospital for Sick Children, Toronto, during the period of 1950-65 have been studied, and the literature has been reviewed. 2. Arthrogryposis is considered to be caused by a failure of normal development. 3. Respiratory infection in the first five years is the major hazard to life. If these children survive the first five years, the expectation is that they will reach maturity and find a place in the community. 4. Children with upper limb involvement develop remarkably good function which can be improved by carefully planned operations. 5. Operation has a much larger place in the treatment of affected lower limbs. 6. Three out of four children with lower limb involvement can be enabled to walk if tile need for repeated operation is accepted. 7. Excision of the talus is a useful operation in the management of club foot ill arthrogryposis. 8. Early treatment is more effective than late ill controlling deformity and improving function.
THE STRENGTH OF THE MENISCI OF THE KNEE AS IT RELATES TO THEIR FINE STRUCTURE
Authors: Bullough Peter G. , Munuera Luis , Murphy Joseph , Weinstein Allan M. 
Published: February 2018

1. The orientation of collagen fibres of the menisci of the knee has been demonstrated by polarised light microscopy. 2. As might be supposed from its fibre structure, the ultimate tensile strength of the meniscal tissue is dependent upon the axis of loading. 3. The tensile strength of the meniscus is similar to that of articular cartilage.
CONGENITAL PSEUDARTHROSIS OF THE CLAVICLE
Authors: Gibson D. A. , Carroll N. 
Published: February 2018

1. Thirteen cases of congenital pseudarthrosis of the clavicle conforming to the classical picture are presented, together with five cases of pseudarthrosis occurring for various other reasons, and nine cases of congenital pseudarthrosis that form a special group because there was a strong family history. 2. Treatment, if desired by the patient, is easy, but should be deferred until the age of four or five years. 3. The etiology remains obscure. Our embryological study does not support the theory that the clavicle normally develops from two ossification centres that may fail to coalesce. Although in thirteen of our patients there was no family history of pseudarthrosis, there was another group of nine patients who presented a strong family history, and it seems certain that in some instances congenital pseudarthrosis of the clavicle can be transmitted genetically.
CONGENITAL PSEUDARTHROSIS OF THE CLAVICLE
Authors: Owen Robert 
Published: February 2018

1. Thirty-three cases of congenital pseudarthrosis of the clavicle are presented. 2. The lesions all occurred in the right clavicle and are thought to be due to abnormal intrauterine development rather than non-union of birth fractures. 3. Methods of treatment are reviewed. Excision and bone grafting is favoured.
DUPUYTREN'S CONTRACTURE
Authors: Honner Richard , Lamb D. W. , James J. I. P. 
Published: February 2018

1. The results in 138 hands operated on for Dupuytren's contracture are analysed and compared with those in other series. 2. Contracture ofthe metacarpo-phalangeal joint can be expected to respond well to operation, whereas the outlook in the case of contracture of the proximal interphalangeal joint is generally poor. 3. The reasons for this difference are examined. 4. The advantages of early operation for contracture of the proximal interphalangeal joint are stressed.
FRACTURES OF THE DENS [ODONTOID PROCESS]
Authors: Schatzker Joseph , Rorabeck Cecil H. , Waddell James P. 
Published: February 2018

1. Thirty-seven cases of fracture of the dens have been studied. 2. The incidence of non-union was high: 64 per cent after apparently adequate closed treatment. 3. Possible causes of the high incidence of non-union have been studied : attention is drawn to the effect of displacement and to that of posterior displacement in particular. 4. Non-union of the dens with potential instability at the atlanto-axial joint is not acceptable in a patient who expects to lead a normal active life. 5. Atlanto-axial fusion is the method of choice in the treatment of instability ; once that has been secured, pseudarthrosis of the dens is no longer significant.
RECURRENT SUBLUXATION OF THE PATELLA ON EXTENSION OF THE KNEE
Authors: Dandy D. J. 
Published: February 2018

1. Eight patients are described in whom the patellae subluxated laterally on every extension of the knee. This is an unusual type of recurrent subluxation. It may recover completely, or remain symptom-free for many years, or increase in severity so that the patient seeks treatment for relief of pain and joint effusion, or progress to frank dislocation. 2. Each patient was examined and the probable causes were analysed. The bayonet deformity was present in twelve of the sixteen knees. A new observation is made on the relationship of tibial crest and tubercle in this condition.
BILATERAL APLASIA OF THE TIBIA, POLYDACTYLY AND ABSENT THUMB IN FATHER AND DAUGHTER
Authors: Pashayan H. , Fraser F. C. , McIntyre J. M. , Dunbar J. S. 
Published: February 2018

1. A family is reported in which tibial aplasia with polydactyly of hands and feet and absent thumbs occurred in a father and daughter. 2. The evidence suggests the existence of an autosomal dominant mutant gene that causes absent thumbs and manual polydactyly, with or without varying degrees of tibial hypoplasia and pedal polydactyly.
RADIAL PALSY FOLLOWING MUSCULAR EFFORT
Authors: Lotem M. , Fried A. , Levy M. , Solzi P. , Najenson T. , Nathan H. 
Published: February 2018

1. Three cases of paralysis of the radial nerve after intensive muscular effort in extension of the elbow are described. Clinical and electrophysiological evidence is recorded. 2. There was motor and sensory affection of varying degree and extent in the distribution of the radial nerve. 3. The type of lesion in each case was that of neurapraxia, and rapid spontaneous recovery occurred in each case. 4. The level of the lesion was in the arm, below the origin of the branches to the triceps. 5. The cause of the lesion was thought to be compression by a fibrous arch related to the lateral head of the triceps. 6. The cases are discussed in relation to other instances of compression of nerves by fibrous arches, and an explanation is advanced for spontaneous recovery.
INTRA-ARTICULAR RHEUMATOID NODULES OF THE KNEE
Authors: Chamberlain M. Anne 
Published: February 2018

1. Eight patients with rheumatoid arthritis had an intra-articular nodule in one or both knees causing mechanical symptoms. 2. The nodule was on the lateral side of the knee and interfered with walking. It caused a click and painful instability of the knee at about 15 degrees of flexion. 3. Surgical excision of the nodule, which was attached to the synovial membrane, abolished the symptoms.
POLYMYALGIA RHEUMATICA
Authors: Mowat Alastair G. , Camp A. Virginia 
Published: February 2018

1. Polymyalgia rheumatica is a disease of unknown cause, manifested by severe pain and stiffness of the muscles of the shoulder and pelvic girdles, which may be accompanied by a variety of other systemic symptoms. 2. Twenty-three patients with this condition are reviewed. 3. The difficulties of diagnosis, especially when presenting as an orthopaedic problem, are discussed.
OSTEOID OSTEOMA OF THE SKULL
Authors: Prabhakar B. , Raja Reddy D. , Dayananda B. , Rao G. Raghava 
Published: February 2018

1. A case of osteoid osteoma of the skull is reported, with characteristic clinical, radiological and pathological features. 2. Osteoid osteoma of the skull has not previously been reported.
SYNOVECTOMY OF THE KNEE IN JUVENILE RHEUMATOID ARTHRITIS
Authors: McMaster Michael 
Published: February 2018

1. Opinion is divided as to the value of synovectomy of the knee in juvenile rheumatoid arthritis. 2. Between 1964 and 1970 thirty synovectomies of the knee were performed in twenty-seven children, who have now been kept under review for one to eight years. Three have required a second operation. 3. The operative findings at various stages are presented and discussed, with special reference to the effect on growth of the limb. 4. Synovectomy is a useful procedure which should be reserved for cases where effusion persists despite nine months of conservative treatment and performed before signs of bone erosion appear.
PSEUDOMALIGNANT OSSEOUS TUMOUR OF SOFT TISSUE
Authors: Chaplin D. M. , Harrison M. H. M. 
Published: February 2018

1. Two cases of pseudomalignant osseous tumour of soft tissue are reported and added to the nineteen cases in the literature. 2. The clinical and histological features are described and distinguished from myositis ossificans, osteogenic sarcoma in soft tissue and parosteal fasciitis. 3. In one case the non-malignant nature of the lesion has been confirmed by its spontaneous regression.
CONGENITAL DIASTASIS OF TIBIO-FIBULAR MORTISE
Authors: Tuli S. M. , Varma B. P. 
Published: February 2018

1. Two cases of congenital diastasis of the inferior tibio-fibular mortise are described. 2. No previous description of this condition has been found in the literature. 3. it is suggested that the cause is osteochondrosis of the distal tibial epiphysis associated with a club foot.
MOTION STUDIES OF THE LUMBAR SPINE
Authors: Pennal George F. , Conn Garson S. , McDonald Glen , Dale Gordon , Garside Henry 
Published: February 2018

1. This is a preliminary report of an attempt to determine an objective reference point or "point of motion" during flexion and extension of the lumbar spine. 2. The method described uses superimposition of lateral radiographs taken in flexion and extension with the patient standing. 3. In seventy-eight radiographically normal subjects with no symptoms a "point of motion" was determined for each of the lowest three disc levels. At each level these points clustered within a specific zone approximately 2·5 centimetres square. Sixty-four per cent fell within a square centimetre. 4. In a comparative study of twenty-four patients with confirmed pathology, the "point of motion" fell outside the larger zone at the level of pathological change in 65 per cent of the disc levels. 5. The determination of the "point of motion" is a special technique for studying spinal motion. Its role as a diagnostic and prognostic aid in assessing patients with back pain is the subject of continuing study.
SCOLIOSIS AFTER THORACOPLASTY
Authors: Loynes R. D. 
Published: February 2018

1. The results of 243 thoracoplasty operations are discussed. It was found that scoliosis developed in over 99 per cent of cases and that the curve was convex towards the side of operation. The angle of curvature correlated closely with the number of ribs removed. 2. If the head, neck and tubercle of the rib and the transverse process of the corresponding vertebra were all removed the degree of scoliosis was increased, whereas if a thoracoplasty was performed with apicolysis and embedding of the scapula the spinal deformity was less. Possible explanations for these phenomena are discussed. 3. No evidence was found to support the theory of causation by imbalance between the paired "pneumatic cylinders" (lungs and thoracic cage) supporting the thoracic spine. 4. The scoliosis was found to progress for many years; some factors influencing this course are discussed. 5. No correlation was found between the age of the patient at the time of thoracoplasty and the degree of subsequent scoliosis, but severe spinal deformity can arise even in older adults.
CORRECTION OF ROTATIONAL MALUNION OF A PHALANX BY METACARPAL OSTEOTOMY
Authors: Pieron A. P. 
Published: February 2018

1. Rotational deformity of a finger caused by malunion of a phalangeal fracture has been corrected by metacarpal osteotomy. 2. Because of the anatomical arrangement of the metacarpo-phalangeal joint this method gives good control of the distal phalanges. 3. Division through the metacarpal rather than through the phalanx avoids adhesions in the flexor and extensor mechanisms and in the joints of the fingers, allows early mobilisation and is an easier procedure.
CHIARI OSTEOTOMY FOR ACETABULAR DYSPLASIA IN YOUNG SUBJECTS
Authors: Colton C. L. 
Published: February 2018

1. The results of Chiari pelvic osteotomy have been examined two to six years after operation in a group of eighteen patients with persisting acetabular dysplasia in the second and third decades. 2. The analysis suggests that for a good clinical result it is essential to create a relationship of the new outer acetabular lip to the original lip so that the CE angle is between 20 and 40 degrees and the roof angle is between 10 degrees below and 20 degrees above the horizontal. 3. This may be achieved by a pelvic osteotomy immediately above the joint capsule, angled 10 degrees upwards and inwards and displaced by 50 per cent of the pelvic thickness. 4. Details of the operative technique using a Smith-Petersen approach are presented.
MICROVASCULAR SURGERY IN ORTHOPAEDICS AND TRAUMATOLOGY
Authors: Tamai Susumu , Sasauchi Nobuyuki , Hori Yoshihide , Tatsumi Yoshitaka , Okuda Hisao 
Published: February 2018

1. The history of microvascular surgery is reviewed; the necessary instruments and the technique of suture are described. 2. Modern trends in the experimental and clinical applications in orthopaedic surgery and traumatology are discussed. 3. The authors emphasise the usefulness of this technique in tissue transplantation and in the reconstruction of microvascular injuries of the musculoskeletal system.
THE NATURAL HISTORY OF THE RHEUMATOID METACARPO-PHALANGEAL JOINT
Authors: McMaster Michael 
Published: February 2018

1. One hundred and twenty-six metacarpo-phalangeal joints affected by rheumatoid arthritis were studied macroscopically at either synovectomy or arthroplasty. 2. The sites and extent of the initial erosion corresponded with the sites and size of the synovial pouches. 3. The areas of cartilage degeneration were related to the degree of flexion, ulnar deviation and subluxation of the proximal phalanx on the metacarpal head. 4. The routine radiographic findings were not a true reflection of all the pathological changes within the joint. 5. It is suggested that by encouraging joint movement and preventing deformity the degree of cartilage degeneration may be diminished.
ARTHROPLASTY OF THE FOREFOOT IN RHEUMATOID ARTHRITIS
Authors: Barton N. J. 
Published: February 2018

1. The results of arthroplasty of the forefoot in thirty-eight patients with polyarthritis have been analysed in detail. Sixty-five feet had been operated on by one of three different techniques–Kates-Kessel-Kay, Fowler or Clayton–though sometimes with modifications. 2. The subjective results were remarkably good. The patients were completely satisfied with forty-two operations, satisfied in most respects with twenty-one, and dissatisfied with only two. 3. The commonest cause of persistent pain was prominence of one metatarsal stump; great care must be taken at the time of operation to ensure that the metatarsals are trimmed to equal length. 4. The objective results were less satisfactory. The lateral four toes were usually functionless, the gait was never normal and the walking distance was still restricted, though often by other factors. The operation, therefore, should be carried out only in patients with severe pain and disability. 5. A comparison of the results of the three different techniques of operation showed no major differences.
THE NAIL-PATELLA SYNDROME
Authors: Valdueza A. Fidalgo 
Published: February 2018

1. Three families with the characteristic changes of the nail-patella syndrome are reported. In addition to the well established bone and nail defects they had soft-tissue contractures, web formation around the elbows and muscular hypoplasias. The literature on soft-tissue changes is reviewed and their importance emphasised. 2. Asymmetrical joint development is considered to be a characteristic feature of the syndrome. 3. The incidence of renal disease in our families is recorded. 4. The literature on the basic defect is reviewed. The likelihood of a primary alteration in connective tissue chemistry is considered.
THE USE OF SPLINTAGE IN THE MANAGEMENT OF PARALYTIC DISLOCATION OF THE HIP IN SPINA BIFIDA CYSTICA
Authors: McKibbin B. 
Published: February 2018

1. A specially designed splint is described with which it is possible to maintain the reduction of a paralytic dislocation in a child with spina bifida cystica. The results of its use in a series of thirteen cases are recorded. 2. It is suggested that all such children presenting in the first year of life, in whom the power of the flexor and adductor muscle groups is preserved, should be treated initially in this way until the prognosis for the individual can be accurately assessed. 3. The theoretical implications of the findings are discussed.
AMPUTATION IN OSTEOSARCOMA
Authors: Sweetnam Rodney 
Published: February 2018

1. The question whether amputation for lower femoral osteosarcoma should be by disarticulation of the hip or through the upper femur to leave a stump is discussed. 2. Sixty-eight such patients are reviewed. Thirty were treated by disarticulation and thirty-eight by through-femur amputation. 3. There was a 16 per cent incidence of stump recurrence after through-femur amputation, but none after disarticulation. Comparison of survival was not conclusive. 4. Disarticulation of the hip is advised.
EXCISION OF THE DISTAL END OF THE ULNA IN RHEUMATOID ARTHRITIS
Authors: Rana N. A. , Taylor A. R. 
Published: February 2018

1. The results of excision of the distal end of the ulna in eighty-six wrists of seventy patients suffering from rheumatoid arthritis are presented. 2. There was relief of pain in 93 per cent and restoration of full rotation in 87 per cent. 3. Further destructive changes of the radio-carpal joint were seen in 85 per cent, but these did not affect the good clinical results.
LONG-TERM CONSEQUENCES OF STABLE FRACTURES OF THE THORACIC AND LUMBAR VERTEBRAL BODIES
Authors: Young M. H. 
Published: February 2018

1. The late consequences of stable fractures of the thoracic and lumbar spine have been assessed in a series of workmen. The incidence of symptoms has been recorded and an attempt made to assess the degree of associated incapacity. 2. It has been found that most patients continue to have some symptoms attributable to the back injury and that approximately one in five of the patients who attended for review was partially or completely incapacitated as a consequence of such symptoms. 3. The persistence of symptoms was found to be unrelated to the severity of fracture, to its level, to the presence of radiological evidence of degenerative change, or to the age of the patient. 4. Persistent symptoms were found more commonly in those patients who had received more treatment. The implications of this observation are discussed.
FRACTURE OF THE NECK OF THE RADIUS WITH MEDIAL DISPLACEMENT OF THE HEAD
Authors: Ghawabi M. H. El 
Published: February 2018

1. Three cases of fracture of the neck of the radius with medial displacement of the head are described. 2. It is proposed that such injuries be classified into two types: 1) displacement of the radial head without dislocation of the elbow; and 2) displacement during posterior dislocation of the elbow.
