ETIOLOGY OF PERONEAL SPASTIC FLAT FOOT
Authors: Harris R. I. , Beath Thomas 
Published: February 2018

1. Peroneal spastic flat foot is a term loosely and often inaccurately used to describe rigid valgus feet developing from widely different causes. 2. The most common causes are two anomalies of the bones of the tarsusâthe calcaneonavicular bar, and the talocalcaneal bridge. The first was described in 1921 by Sloman and in 1927 by Badgley; the other is described for the first time in this paper as an etiological factor in rigid flat foot though it has been recognised by anatomists for fifty years as a skeletal variation. The term peroneal spastic flat foot, as applied to these cases, is inaccurate since there is no spasm of the peroneal muscles. The deformity is a fixed structural deformity due to anomalous bone structure, and the apparent spasm of peroneal muscles is in reality an adaptive shortening. A better term would be rigid flat foot due to talocalcaneal bridge or calcaneonavicular bar. 3. The smaller group of patients who suffer from inflammatory lesions of the tarsal joints, chiefly due to rheumatoid arthritis, do in fact develop valgus deformity from peroneal spasm. The resemblance between the two groups is superficial and it is limited to the apparent similarity of the deformity. Though it might be justifiable to designate this type as peroneal spastic flat foot, it would be better to use the more accurate titleâarthritic flat foot with peroneal spasm. 4. Lipping of the upper margin of the talonavicular joint strongly suggests the existence of one or other of the congenital anomalies. Both anomalies are visualised only by special radiological projections.
THE CONGENITAL DISCOID MENISCUS
Authors: Smillie I. S. 
Published: February 2018

1 . A personal series of twenty-nine discoid menisci is reviewed. 2. Three anatomical types are recognised and described. 3. The characteristic lesions incurred by each type is recorded. 4. The anatomical and pathological features of the specimens are compared with those of cases previously recorded. 5. A discoid medial meniscus is described, and compared with the only other specimen known to be recorded in the literature.
TYPES OF DISPLACEMENT IN FRACTURES OF THE FEMORAL NECK
Authors: Linton Per 
Published: February 2018

1. Various types of fracture of the femoral neck represent different stages of one and the same displacing movement. 2. The displacement first produces an "abduction fracture" and terminates in an "adduction fracture," passing through the stage of an " intermediary fracture" which is less well recognised. 3. These three types of fracture occur in response to the same injury and they differ only in the degree of displacement. 4. It is a mistake to believe that in " adduction fractures" the femoral head lies medially to the collum : it lies posteriorly. 5. "Impaction" is no more than the first stage of displacement of fractures in which there is limited displacement, with contact still maintained between the fragments. 6. An "impacted fracture" is not necessarily stableâif there is additional strain it may progress to the next stage of a displaced and unstable fracture. 7. These principles apply not only to fractures of the femoral neck but to all other fractures at the ends of long bones.
SKIN GRAFTING BY CROSS-LEG FLAPS
Authors: Braithwaite Fenton , Moore F. T. 
Published: February 2018

1. After limb injuries with loss of skin and subcutaneous tissue, full-thickness skin flaps afford the most satisfactory cover. It is particularly important to replace unstable and scarred skin before attempting bone reconstruction and similar operations. 2. In the leg and foot, full-thickness skin cover is conveniently obtained by the cross-leg flap technique. The blood supply of such flaps is considered and the technique of operation is described. Free excision of avascular scar tissue is essential. 3. "Delayed transfer" of the flap is advisable unless conditions are favourable; two methods are considered. 4. Immobilisation in plaster is the most satisfactory method of fixation of the limbs after attachment of the flap. Muscle exercises are performed throughout the period of treatment in order to minimise joint stiffness and shorten convalescence. 5. The cross-leg flap technique should not usually be used in children, young women, or the aged and mentally infirm. Contra-indications include arthritis of the knee and hip joints because there is danger of joint stiffness. 6. Vascular complications of cross-leg skin grafting are discussed.
TREATMENT OF GIANT-CELL TUMOURS OF BONE
Authors: Prossor T. M. 
Published: February 2018

1. Twenty-five cases of benign giant-cell tumour of bone, treated at Westminster Hospital, London, are reported. 2. The diagnosis can often be made on clinical and radiographic grounds alone but biopsy is sometimes necessary and seldom, if ever, contra-indicated. 3. Some cases may best be treated by excision, but in general irradiation is the treatment of choice. 4. Details of treatment by irradiation are given.
SOLITARY PLASMOCYTOMA OF THE SPINE
Authors: Raven Ronald W. , Willis R. A. 
Published: February 2018

1. A case of solitary plasmocytoma of the thoracic part of the spine, verified by necropsy, is described. 2. A brief review is given of eighteen acceptable cases of solitary plasmocytoma of bone. 3. Of the eighteen patients, fifteen were men; the five spinal tumours were all in men. 4. Diagnosis requires: a) biopsy identification of plasmocytoma; b) exclusion of the possibility of generalised myelomatosis by complete radiography of the skeleton, repeated if necessary at intervals during the ensuing two or three years or longer. 5. A tumour of brief duration, proved to be solitary by careful necropsy, cannot be placed with certainty in the group of truly solitary plasmocytomas; it might have been a precocious first lesion of myelomatosis.
INTER-METACARPAL BONE GRAFT FOR THENAR PARALYSIS
Authors: Brooks Donal M. 
Published: February 2018

1. Sixteen cases of thenar paralysis are reviewed in which a bone graft was inserted between the first and second metacarpals to maintain fixed abduction and opposition of the thumb. 2. The technique of the operation is described and the causes of failure are discussed. 3. The operation is intended for those cases in which tendon transplantation to restore active opposition of the thumb is unsuitable. Rotation of the first metacarpal into full opposition is the most important feature of the operation.
THE ENDOCRINE BASIS FOR SLIPPING OF THE UPPER FEMORAL EPIPHYSIS
Authors: Harris W. Robert 
Published: February 2018

1. An apparatus was designed to determine the shearing strength of the upper tibial epiphysis in the rat. Observations were made with this instrumenton normal animals, on animals receiving growth-hormone, and on animals receiving oestrogen. 2. When the epiphysis separates from the diaphysis, the plane of cleavage is constant, passing through the third layer of the epiphysial plate. 3. Growth-hormone decreases and sex-hormone increases the shearing strength of the epiphysial plate. These changes are due to alterations produced by these two hormones in the thickness of the third layer of the epiphysial plate. 4. It is suggested that these findings may be of significance in providing an anatomical basis for slipping of the upper femoral epiphysis in man, especially when it is associated with the adiposo-genital syndrome or with rapid adolescent growth.
CONGENITAL TORTICOLLIS
Authors: Hulbert K. F. 
Published: February 2018

1. One hundred cases of torticollis and 117 cases of sternomastoid tumour have been reviewed. 2. Congenital torticollis can be sub-divided into two groups: postural and muscular. 3. Congenital postural torticollis is present at birth; it is not associated with a sternomastoid tumour; it is transient in nature; and it does not require operation for its relief. 4. Congenital muscular torticollis is preceded by a sternomastoid tumour which is clinically evident in one-fifth of all cases. 5. The ischaemic theory of the causation of sternomastoid tumours is not supported by recent histological investigations. Some other cause, which probably is operative before birth, must be sought. 6. Four-fifths of all cases of sternomastoid tumours resolve spontaneously and leave no deformity. Excision of the tumour in infancy is therefore unjustifiable. 7. Open division of the muscle and of the cervical fascia in congenital muscular torticollis cures the deformity but leaves an unsightly scar. 8. Subcutaneous tenotomy can be relied upon to cure the deformity if post-operative treatment is carried out skilfully and assiduously over a prolonged period. 9. If complete correction is not gained at the time of subcutaneous tenotomy a better result can be assured by open division of the upper end of the muscle through an incision within the hair line.
AN EXPERIMENTAL STUDY OF TENDON GROWTH IN THE RABBIT
Authors: Crawford G. N. C. 
Published: February 2018

1. Small indian ink marks were made at intervals along the length of tendons in the limbs of young rabbits, and the distance between the marks was measured during the operation. The rabbits were killed two to three months later, and the amount of longitudinal growth that had occurred was determined by re-measuring the distance between the marks. 2. The experiments showed that the whole of the tendon grows interstitially in length, but that maximal growth occurs near the muscle-tendon junction. 3. Histological examination of the tendons and control experiments involving adult tendons indicated that growth was not significantly interfered with by marking the tendons.
THE MOVEMENTS OF BONES AND JOINTS 3. The Synovial Fluid and its Assistants
Authors: MacConaill M. A. 
Published: February 2018

1. Synovial fluid acts mechanically by forming a convergent lubricant film between the fixed and the moving joint surfaces. This term and the underlying theory are explained. 2. The fatty pads assist lubrication by reducing the "mechanical curvature" in joints with more highly curved surfaces. 3. The intra-articular discs and menisci increase the "mechanical curvature" in joints with surfaces of small curvature. 4. Sesamoid bones exert a "bow-string pressure" upon the bones with which they articulate. This is a corollary from the theory of lubrication.
CHERUBISMâA FAMILIAL FIBROUS DYSPLASIA OF THE JAWS
Authors: Jones W. A. , Gerrie John , Pritchard Joseph 
Published: February 2018

1. A condition of fibrous dysplasia of the jaws occurring in four brothers and a sister has been under observation since 1931. 2. Three of the five patients have been operated upon for correction of grotesque deformity, with satisfactory results. 3. The pathological nature of the disorder is discussed.
PSEUDARTHROSIS OF THE TIBIA IN CHILDHOOD
Authors: McFarland Bryan 
Published: February 2018

1. The results of the by-pass grafting operation in eleven cases of pseudarthrosis of the tibia in childhood are presented. 2. The operation was successful in securing sound bone union in nine cases, and unsuccessful in two. 3. The causes of failure in the two unsuccessful cases are analysed. 4. The possible causes of occurrence and persistence of tibial pseudarthrosis in childhood are discussed. 5. It is suggested that the pseudarthrosis results from a fatigue fracture of a congenitally abnormal tibia, but that its persistence depends entirely on mechanical factors. 6. There is evidence to suggest that the underlying congenital abnormality may arise from dysplasia of the mesenchyme.
THE MANUBRIO-STERNAL JOINT IN ANKYLOSING SPONDYLITIS
Authors: Savill Douglas L. 
Published: February 2018

1. Pathological changes occurred in the manubrio-sternal joint in 72 per cent of a series of sixty-one cases of ankylosing spondylitis. 2. In all the twenty-one patients over the age of thirty-five years the joint was undergoing a process of fusion that was found in only seven of sixty healthy persons in the same age group. 3. In the age groups twenty-five to forty-four, thirty-five out of forty-three patients with ankylosing spondylitis showed abnormality that was noted in but three of the forty healthy controls. 4. The changes in the manubrio-sternal joint are similar to those which occur in the sacro-iliac joint. 5. The accessibility of the manubrio-sternal joint makes it a convenient source of pathological material for the further histological study of the disease.
SOME EXPERIENCES IN THE TREATMENT OF OSTEOMYELITIS OF INFANTS
Authors: Athanassiadis Ch. N. 
Published: February 2018

1. The clinical findings and results in seventeen patients under two years of age, suffering from acute osteomyelitis, have been studied and compared with forty-eight similar cases treated without penicillin. 2. The results in the penicillin-treated group were not greatly superior to those in the control group and did not justify the high hopes that have been entertained for penicillin as a certain cure for osteomyelitis.
TROCHANTERIC FRACTURES
Authors: Evans E. Mervyn , Wales Swansea S. 
Published: February 2018

1. A series of 110 cases of trochanteric fractures treated by internal fixation with the Capener-Neufeld nail-plate is presented. The age incidence, mortality, complications and functional results are discussed in detail. 2. The results are compared with those of two series of cases treated conservatively: a) 101 cases treated conservatively in hospital; b) 25 cases sent home by reason of shortage of hospital beds. 3. From a consideration of these three series, and from study of similar series of cases reported in the literature, it is concluded that routine operative treatment of trochanteric fractures offers the advantages of lowered mortality, improved function, economy of hospital beds, and greater comfort and mobility of the patient. 4. Certain points in the management of cases during the operation and in the convalescent period are discussed.

THE MOVEMENTS OF BONES AND JOINTS
Authors: MacConaill M. A. 
Published: February 2018

1. All articulating cartilages are fibrocartilages. 2. The articular cartilages of the synovial joints are largely composed of collagen fibres. 3. These fibres form a dense network, the fibres of which run obliquely between the articular surface and the bone. 4. This network is operative when the parts are at rest and in contact under pressure. It takes the tensile component of the resultant shear stress, and is a postural mechanism of the joint. 5. The articular cartilage is most heavily chondrified at its centre, between the juxta-synovial and juxta-osseous parts. 6. The technique for demonstrating the fibrous structure is described.
TARSAL MOVEMENTS
Authors: Shephard Edmund 
Published: February 2018

1) Supination and pronation are the only material tarsal movements; other terms describe their hypothetical components only. 2) The subtalar and talo-navicular joints form a single joint functionally, which may be called the peritalar joint. 3) Peritalar movement comprises a wide range of supination and pronation of the foot about an axis which passes from the tuberosity of the calcaneum upwards, forwards and slightly medially to the neck of the talus. 4) Midtarsal movement comprises a narrow range of supination and pronation of the foot about an axis similar to that of peritalar movement. 5) Tile peritalar and midtarsal joints are thus oblique hinge joints.
OBSERVATIONS ON HALLUX VALGUS
Authors: Hardy R. H. , Clapham J. C.R. 
Published: February 2018

A survey of this type cannot be used to point to any definite factor or factors predisposing to the development of hallux valgus. Nevertheless, a comparison of measurements in the morbid and control groups shows several outstanding differences: 1) There was a high degree of correlation between valgus and intermetatarsal angle in the two groups combined (coefficient, 0Â·7) but the correlation was higher in those cases with a degree of valgus greater than 25 degrees than in the remainder (coefficients, 0Â·36 and 0Â·53). 2) In the control group the first metatarsal was longer than tile second by a mean measure of 2 millimetres; in the morbid group by a mean measure of 4 millimetres. For a high degree of valgus and a low intermetatarsal angle the first metatarsal tends to be longer than the second by a significantly greater amount than when the high valgus is associated with iligh intermetatarsal angle. 3) In 90 per cent of the control cases there was a lateral displacement of the medial sesamoid of the first metatarsal of 3 degrees or less, whereas 88 per cent of the morbid group showed a displacement of 4 degrees or more. There was very little overlap in the distributions of this observation in the two groups. There was a high correlation between the degree of this displacement and the severity of hallux valgus. 4) Rotation of the hallux was not observed among the controls; in the morbid group those cases showing rotation had an average degree of valgus of 36 degrees while the rest had an average of 19 degrees. The mean degree of valgus in the morbid group was 32Â·0 degrees and that of the controls 15Â·5 degrees. The mean angle between the axes of the first and second metatarsals was 13Â·0 degrees in the morbid group and 8Â·5 degrees in the controls. Since tile morbid group consisted largely of women (98 per cent) it is important to know that in the control group the only measure showing a statistically significant sex difference is that of intermetatarsal angle, but that, even so, the mean difference is only 1Â·3 degrees. Thus tile sex difference between the two groups is probably only of minor importance. The role of age in influencing the observations cannot be clearly elucidated from the data at present available. It can only be stated that there is no positive indication that age is a controlling factor in the departure observed in the morbid group from the control observations.
TWO CURVE PATTERNS IN IDIOPATHIC STRUCTURAL SCOLIOSIS
Authors: James J. I.P. 
Published: February 2018

Infantile idiopathic scoliosis is a structural scoliosis seen in infants, usually boys, with the major curve to the left in almost all cases, and almost invariably in the mid-or lower thoracic region. It occasionally disappears, but in general the curve tends to increase. In the absence of any discoverable etiology it is termed "idiopathic" and it is believed not to differ in essentials from the more common adolescent scoliosis. Lumbar idiopathic scoliosis has a good prognosis as to deformity, but leads more often than any other curvature to degenerative arthritis and pain in later life.
AN IRREGULAR, FAMILIAL CHONDRO-OSSEOUS DEFECT
Authors: Jackson W. P.U. 
Published: February 2018

Three elderly sibling dwarfs are reported from a large and otherwise normal family. Their condition is an unusual and irregular form of cartilaginous defect, combined with club-feet, and bearing some resemblance to the Morquio type. A brief consideration of the literature of the generahised developmental bony syndromes shows confusion of thought and nomenclature. A plea is therefore made for simplification and a rational and simple grouping of these conditions is attempted. It seems particularly desirable that many confusing names for particular syndromes should be scrapped (for example, dyschondroplasia, chondro-osteodystrophy), although quite evidently the terms achondroplasia and osteogenesis imperfecta must remain because of their long-standing and general usage. Incidentally I have suggested elsewhere (Jackson 1951) that the name cleido-cranial dysostosis should be dropped, because it tends to lead the investigator away from the clinically more important lesions in the teeth and the cartilage bones of the pelvis and legs. It seems reasonable to confine the nomenclature of these various syndromes to the names used in the above classification, or something on those lines.
TISSUE DIFFERENTIATION IN MALIGNANT SYNOVIAL TUMOURS
Authors: King E. S. J. 
Published: February 2018

1. A series of twenty-one cases of synovial tumour is tabled and the histological appearances are discussed. 2. The characteristic histological forms, (a) mucin formation, (b) synovial spaces, (c) endothelial and "gland" spaces and (d) epithelium-like tissue, are described. 3. These all arise by differentiation of connective tissue cells which occur throughout the connective tissue part of the limbs. 4. Though more commonly found in regions where synovial membrane is present, they are not confined to such special areas. 5. The tumours are classified on a histological and not a histogenetic basis.
NERVE COMPRESSION BY SIMPLE GANGLIA
Authors: Brooks Donal M. 
Published: February 2018

1. Thirteen cases are reported of nerve compression by a ganglion. At operation a connection between the ganglion and the neighbouring joint was established in many instances. 2. It is suggested that so-called ganglia of the nerve sheath and simple ganglia are anatomical varieties of the same entity. 3. The treatment of choice is excision of the ganglion. If this procedure is technically difficult, puncture is advisable. 4. Recovery of sensibility after operation was good. Motor recovery was poor when damage to motor fibres occurred during excision of the ganglion or when paralysis had been present for more than eighteen months.

CERVICAL HYPEREXTENSION INJURIES WITH PARAPLEGIA
Authors: Kaplan C. J. 
Published: February 2018

1. The literature on paraplegia complicating hyperextension injuries of the cervical spine is reviewed, and the lack of any definite explanation of the mode of interference with cord function is noted. 2. A case is described in which a detailed dissection of the post-mortem specimen was carried out. On the basis of the findings it is suggested that one cause of the suppression of cord function in such injuries is thrombosis of the spinal arteries and liquefaction-necrosis of the cord.
