BANKART'S OPERATION FOR RECURRENT DISLOCATION OF THE SHOULDER
Authors: Dickson J. W. , Devas M. B. 
Published: February 2018

1. Fifty cases of recurrent dislocation of the shoulder are reported, operated upon by Bankart and his colleagues from 1925 to 1954. 2. This is the first detailed survey of his patients, some of whom we were unable to trace. 3. It has been confirmed that the operation is successful, and that a full range of movement can be regained after operation, though not in every case. 4. Two cases treated unsuccessfully are described and discussed.
SOME OBSERVATIONS ON CONGENITAL DISLOCATION OF THE HEAD OF THE RADIUS
Authors: Caravias D. E. 
Published: February 2018

1. Radiological criteria in the diagnosis of congenital dislocation of the head of the radius are suggested. 2. Some of the radiographic features described as characteristic of congenital dislocation of the head of the radius may be found also in post-traumatic dislocation of the radial head.
TREATMENT OF OSTEOCHONDRITIS DISSECANS
Authors: Smillie I. S. 
Published: February 2018

1. The record is presented of an attempt to treat osteochondritis dissecans on idealistic lines. 2. The operative technique to be adopted in the various circumstances likely to be encountered in the knee joint is described. Two cases affecting the talus are recorded. 3. The radiological appearance has become virtually normal in twenty-seven cases (the remaining four are recent); healing has been observed directly in seven cases in which a second operation to remove the means of internal fixation was necessary; and the patients' complaints have been eliminated, but the long term results of treatment are unknown. 4. Suggestions are made for possible developments in the technique of operation.
MOVEMENTS OF THE LUMBAR SPINAL COLUMN
Authors: Allbrook David 
Published: February 2018

1. Previous studies of the movements of the lumbar spine are criticised in the light of new observations from radiograph tracings. It is shown that, contrary to recent teaching, the lumbar spine is a very mobile part of the vertebral column. 2. The movement of the lumbar spine is analysed. It is shown that the lower vertebrae have the most movement, and that the range gradually becomes less in the upper lumbar spine. 3. This movement may be roughly correlated with the incidence of spurs arising from the anterior margin of the vertebral bodies. 4. These spurs are shown to arise in the anterior longitudinal ligament; they are probably caused by intermittent pressure from the intervertebral disc lying behind the ligament.
ANTERIOR DISLOCATION OF THE HEAD OF THE RADIUS ASSOCIATED WITH UNDISPLACED FRACTURE OF THE OLECRANON IN CHILDREN
Authors: Hume A. C. 
Published: February 2018

1. Three cases of anterior dislocation of the head of the radius associated with an undisplaced fracture of the olecranon are described. 2. A combination of pronation of the forearm and hyperextension of the elbow is suggested as a possible mechanism.
REPORT OF THE TREATMENT OF EXPERIMENTAL FAT EMBOLISM WITH HEPARIN
Authors: Gardner A. M. N. , Harrison M. H. M. 
Published: February 2018

1. Reports of the lipaemia-clearing effect of heparin suggested that this drug might be of therapeutic value in fat embolism. 2. In an experimental trial with rats, heparin was found both to accelerate death and to increase the number of deaths after fat embolism. 3. It is accordingly concluded that a clinical trial of heparin in human fat embolism would not be warranted.
THE REACTIONS OF INJURED HUMAN ARTICULAR CARTILAGE
Authors: Landells J. W. 
Published: February 2018

1. The lines of fracture confirm the suggestions of earlier authors on the lines of strength in cartilage, with the additional feature of a transverse plane of weakness at the apex of the calcified zone. 2. The normal nutrition of cartilage is synovial, and access of a free blood supply is followed by destruction of hyaline articular cartilage. 3. Minor traumatic events in the articular lamella are common, particularly in osteoarthritic joints; the results of these on the cartilage are like the changes of osteoarthritis. 4. The removal of uncalcified cartilage can be described in two stages of a physico-chemical kind; the removal of calcified cartilage is a single cellular process. 5. There is evidence that the carbohydrate moiety of cartilage is present in two separable phases, one fixed to collagen, the other free. 6. The repair mechanisms after fracture are those available to restore the damage of osteoarthritis, and reasons can be shown why in fact they are ineffective.
THE RESULTS OF TREATMENT OF SLIPPED FEMORAL EPLPHYSIS
Authors: Hall J. E. 
Published: February 2018

1. One hundred and seventy-three hips in 138 patients have been examined and studied in reference to the type of treatment received. 2. Shepherd's method of assessing the results of arthroplasty operations has been adapted to this series. 3. Satisfactory results were found in 77Â·9 per cent of all patients. 4. The value of straight longitudinal traction is questioned. Medial rotation appears to be an essential step in the reduction of the deformity. 5. Manipulation was found to be a relatively safe and effective method of reducing the deformity in patients seen soon after an acute episode, and should be reserved for them. 6. Complications were common after nailing operations, and included subtrochanteric fracture in three cases. 7. Avascular necrosis was the commonest cause of a poor result. The two types of avascular necrosis are discussed. 8. Avascular necrosis was found in 37 per cent of cases in which a manipulation was followed by a nailing operation. 9. Avascular necrosis was not found in any case in which a manipulation was combined with the use of Moore's pins, but such cases were kept under observation for a shorter time. 10. Avascular necrosis was found in 38Â·1 per cent of cases of cervical osteotomy.
THE RELIEF OF TRAUMATIC ARTERIAL SPASM IN THREATENED VOLKMANN'S ISCHAEMIC CONTRACTURE
Authors: Benjamin A. 
Published: February 2018

1. Three cases of traumatic arterial spasm are reported. 2. In each case there was increased tension in a neighbouring myofascial compartment. 3. The cause of this tension was oedema, possibly supplemented in one case by haematoma. 4. Release of tension by splitting the sheath was followed by relaxation of the artery. 5. It is suggested that tension in a fascial compartment may provide the stimulus that maintains arterial spasm and that the consequent ischaemia aggravates the oedema, so that a vicious circle is established. 6. It is further suggested that if spasm persists in spite of the usual measures, including exploration of the artery, the distal myofascial compartment should be decompressed. Division of the deep fascia of the cubital or the popliteal fossa is not enough. 7. Such persistent arterial spasm is uncommon, and further observations are needed to define the significance of increased tension in a distal myofascial compartment.
THE SPEED OF HEALING AFTER FRACTURE OF THE TIBIAL SHAFT
Authors: Ellis H. 
Published: February 2018

1 . A series of 343 tibial shaft fractures proceeding to sound union in adults, and 192 fractures in children, was studied. Groups of fractures differing from each other only in the one particular variable under consideration were compared. 2. The severity of the injury (as assessed by the degree of displacement, of comminution and of compound wounding) was found to be an important determinant of speed of fracture union and of incidence of delayed and non-union. A simple classification of severity of injury is described. 3. Distraction delayed healing. Traction which avoided distraction had no effect on the rate of union of fractures of moderate severity compared with cases of similar severity of injury treated by immobilisation only. Major fractures subjected to traction did take longer to unite on the average, but there was no increase in the incidence of delayed or non-union.
NEUROBLASTOMA IN ORTHOPAEDIC PRACTICE
Authors: Busfield P. I. 
Published: February 2018

1. Neuroblastoma is a disease that may concern the orthopaedic surgeon closely. 2. Six such cases are reported. 3. Early diagnosis may be difficult, but can be achieved if the condition is suspected and an adequate investigation is carried out on suspicion alone. 4. The prognosis in these patients is still poor, but might be improved by a vigorous combination of surgery, irradiation and chemotherapy. The recent advance in treatment with vitamin B 12 may improve the prognosis substantially.
THE RESULTS OF PARTIAL AND TOTAL EXCISION OF THE PATELLA
Authors: Duthie H. L. , Hutchinson J. R. 
Published: February 2018

1. Seventy-seven operations on the patella have been reviewed. 2. There is no evidence that arthritic changes in the femoral condyles are an inevitable sequel of complete excision of the patella. 3. There is a direct relationship between the severity of symptoms after complete excision of the patella and the extent of ossification in the quadriceps tendon. 4. Patello-femoral arthritis after partial excision of the patella may be due to faulty realignment of the patellar ligament and consequent tilting of the patellar remnant towards the femoral condyles.
CONGENITAL DISCOID CARTILAGE
Authors: Ross James A. , Tough Ian C. K. , English T. A. 
Published: February 2018

1. A case of discoid medial cartilage is describeâthe fifth so far recordedâand comparison is made with the previous cases in the literature. 2. The origin of the anomaly, its incidence and clinical features are discussed. 3. The view is expressed that discoid cartilage is a congenital lesion due to abnormal development, fibrocartilage being laid down in mesenchyme which normally disappears in the formation of the joint. It is not the effect of arrest of a normal process or persistence of a normal foetal state. The only time at which a cartilage may be said to be disc-shaped is in the earliest weeks of embryonic life, when the disc or plaque of undifferentiated mesenchyme is present between the developing bones. The central part of this mass disappears early, and the fibrocartilage develops in its peripheral portion. In a ten-weeks'-old embryo (37 millimetres) the cartilages were shown to have a crescentic shape like that of the adult cartilage.
FAMILIAL OSTEOARTHROPATHY OF THE FINGERS
Authors: Allison A. C. , Blumberg B. S. 
Published: February 2018

1. Two unrelated families with a genetically determined arthritis-like syndrome of the joints of the hand and wrist are described. 2. The condition begins before puberty, is relatively painless and is not functionally disabling. The condition resembles that described by Thiemann and appears to fall into the group of avascular necrosis. 3. The appearance of the abnormality is controlled by a single autosomal gene which manifests itself in nearly all persons who are heterozygous for it. Two of the offspring of a marriage between affected persons showed much greater involvement than their siblings. This suggests that they may represent the effect of the abnormal gene in double dose. If this is so, the type of inheritance cannot strictly be regarded as "dominant," since the abnormal homozygote is different from the heterozygote.
THE MANAGEMENT OF PATHOLOGICAL FRACTURE OF THE MAJOR LONG BONES FROM METASTATIC CANCER
Authors: Bremner R. A. , Jelliffe A. M. 
Published: February 2018

1. Problems of management of a pathological fracture of a major long bone through a metastatic cancer deposit are outlined. The relatively short life expectancy of these patients is stressed. 2. The results of treatment of thirty-six consecutive fractures of this type by internal fixation and radiotherapy, and of similar treatment used "prophylactically" on seven occasions, are reviewed. 3. Four-fifths of the patients with lower limb fractures became ambulant with crutches and were able to return home. 4. "Prophylactic" internal fixation and radiotherapy appear to be helpful in selected cases. 5. The theoretical dangers and difficulties of the technique are discussed. They are easily surmountable and have probably been over-emphasised in the past. 6. It is concluded that this is the best method at present available for dealing with this difficult problem.
POSTERO-LATERAL DISLOCATION OF THE KNEE WITH CAPSULAR INTERPOSITION
Authors: Quinlan A. G. , Sharrard W. J. W. 
Published: February 2018

1. Five cases of postero-lateral dislocation of the knee with capsular interposition are described. 2. The mechanism of the injury is considered in the light of the case histories and the findings at operation. 3. The constant clinical findings associated with this injury are described. 4. Open reduction is recommended: with early operation the prognosis for function and stability is good.
TREATMENT OF PERTROCHANTERIC AND BASAL FRACTURES OF THE FEMUR BY IMMEDIATE FIXATION WITH A TWO-PIECE NAIL AND PLATE
Authors: Bremner R. A. , Graham W. D. 
Published: February 2018

1. The results of treatment of 100 consecutive patients with pertrochanteric and basal fractures of the femur treated by early operative fixation with a McKee two-piece nail and plate are reviewed. 2. Technical failures are analysed and discussed. 3. The pattern of mortality is discussed and contrasted with that in a comparable series of patients treated conservatively. 4. It is concluded that early operative fixation is the method of choice in the management of these fractures, and that the McKee pin and plate is a satisfactory and reliable device for securing internal fixation.
DISLOCATION OF THE UPPER END OF THE FIBULA
Authors: Harrison R. , Hindenach J. C. R. 
Published: February 2018

1 . Dislocation of the upper end of the fibula is probably less unusual than the paucity of the published reports suggests. 2. Dislocation may be anterior or posterior, anterior dislocation occurring about twice as often as posterior. Rarely the fibula moves proximally. 3. In most cases a closed manipulation suffices for reduction, and a full and rapid return of normal function follows. 4. Five cases are described. In one case operative reduction was required.
EXPERIMENTAL EPIPHYSIAL INJURY AND FREIBERG'S DISEASE
Authors: Braddock G. T. F. 
Published: February 2018

1. Experiments show relative weakness of the second metatarsal epiphysis at a certain stage of epiphysial maturation. 2. It is shown that at this stage Freiberg's infraction is likely to occur. 3. It has been demonstrated that even gross comminution with disruption of the articular cartilage of the second metatarsal head is compatible with a radiograph of almost normal appearance.
BILATERAL CORACO-CLAVICULAR ARTICULATIONS IN THE AUSTRALIAN ABORIGINAL
Authors: Ray L. J. 
Published: February 2018

1. A pair of clavicles and the corresponding scapulae were found to possess definite articular facets indicating the presence, in life, of a coraco-clavicular joint. 2. The bones are described and illustrated. 3. These cases are compared with others reported in the literature.
TREATMENT OF PARALYSIS OF THE FLEXORS OF THE ELBOW
Authors: Segal Anne , Seddon H. J. , Brooks D. M. 
Published: February 2018

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 hand often limited the usefulness of the limb. In striking contrast the subjective results were in general far better than the objective in patients who had had poliomyelitis. In them the smallest gain can be of functional value.
CORRECTION OF THE OUTWARDLY ROTATED LEG FROM POLIOMYELITIS
Authors: Pauker Emil 
Published: February 2018

1. A method of correcting poliomyelitic lateral rotation deformity of the thigh by transplant of one or more of the hamstring muscles to the femur is described. 2. The results in seven cases are recorded. 3. Though it is emphasised that this is no more than a preliminary communication and the number of patients so treated is small, the satisfactory results suggest that the procedure is mechanically and physiologically sound.
POSTERIOR FUSION OF THE SPINE FOR SCOLIOSIS
Authors: Winchester Ian W. 
Published: February 2018

1. Posterior fusion of the spine in scoliosis cannot be relied upon to maintain correction of the curve or to prevent progression of a vicious resistant curve. It can, however, hold to some extent the correction of a mobile curve and the compensation of a fixed curve. 2. Despite generally poor results as assessed radiographically, the clinical improvement is often gratifying. Most patients claim to be greatly improved: the spine feels stronger, there is less fatigue, and balance is better controlled. Moreover, visible deformity may be improved markedly even though the anatomical correction as observed radiographically is slight (Figs. l0 and 11). 3. It is believed that the true cause of relapse is that the bone formed from sliver grafts remains immature for a long time. Even when incorporated with the immature bone of the child's spine or the mature bone of the adult spine, it remains soft and resilient. When subjected to the stresses and strains of weight bearing and gravity, and then to the unnatural forces which initiated or perpetuated the scoliosis, this immature bone undergoes remodelling to Wolff's Law—like the neck of the femur after slipping of the upper femoral epiphysis. The forces that alter the grafted bone are not only lateral forces but also—perhaps more important—rotational forces. There seems to be a definite link between the degree of rotation and the amount of relapse, correction being maintained best when rotation is least.
PHOSPHATASE ACTIVITY IN THE LIMB BONES OF GROWING RABBITS
Authors: Jeffree Grace M. 
Published: February 2018

1. A quantitative study of phosphatase distribution in the limb bones of growing rabbits is reported. 2. Alkaline phosphatase is present in high concentrations in areas of deposition of new bone. Both local concentrations and the total alkaline phosphatase content of a bone are found to decrease with age. There is good correlation between total alkaline phosphatase activity and monthly increment of weight. 3. Acid phosphatase is present in these bones in greatly less concentrations than alkaline phosphatase. 4. The acid phosphatase of bone shows nearly full activity in the presence of 0·5 per cent formaldehyde. It can be subdivided into two enzymes with characteristically different distributions by the effect of M/100 tartrate on activity. 5. The formaldehyde-stable and tartrate-stable acid phosphatase of rabbit bone (FTS) has a distribution very similar to that of alkaline phosphatase, though very much less in amount, and, like the latter, declines in activity as the bone matures. 6. Tartrate-inhibited, formaldehyde-stable acid phosphatase (FSTI) is found mainly in red marrow and cancellous bone, and full activity persists in mature bone. This enzyme may be associated with resorption and remodelling of bone, or it may represent residual activity under these conditions of the acid phosphatase of developing erythrocytes in the marrow.
VERTEBRA PLANA (CALVÉ)
Authors: Weston W. J. , Goodson G. M. 
Published: February 2018

1. A case of vertebra plana (Calvé) is described and serial radiographs throughout the course of the disease are presented. 2. The initial radiographs showed a vertebra of normal depth which collapsed to a thin disc in fifteen days. Since the symptoms had begun twelve days before the first examination the total time taken to reach this stage was twenty-seven days. 3. The literature has been reviewed for evidence of the underlying pathology of vertebra plana. In the case described biopsy of the affected vertebral body was not carried out, and thus the nature of the underlying change could not be determined.
EARLY DRAINAGE OF PARASPINAL TUBERCULOUS ABSCESSES IN CHILDREN
Authors: Karlen A. 
Published: February 2018

The following preliminary conclusions seem possible. 1. In early cases of Pott's disease of the thoracic spine in children the treatment should include chemotherapy, recumbency and costo-transversectomy. An exception may be made if severe destruction has led to subluxation of the column, when more radical surgery is indicated. 2. Combination of conservative treatment with costo-transversectomy can prevent spread of the disease along the vertebral column, and can lead to regression of this "spondylitis anterior." 3. The abscess can be totally eradicated and the risk of recrudescence therefore diminished.
BILATERAL HEREDITARY MICRO-EPIPHYSIAL DYSPLASIA OF THE HIPS
Authors: Elsbach L. 
Published: February 2018

1. A family is described of which several members in four generations suffered epiphysial growth disturbances of an unusual kind in the capital epiphyses of the femur, with shortness of stature. 2. This disorder forms one of a group of epiphysial growth disturbances which embraces several recognised disorders, whose effects on the epiphyses vary in severity. They may occur sporadically or they may be inherited as recessive or dominant characters. 3. Differentiation depends on the behaviour of the joint line–in other words, whether the epiphysis starts to show defects through inability to sustain the stress of weight bearing. In the most serious cases the picture is that of Morquio-Brailsford's disease; when the changes are less severe the appearance may be that of bilateral Perthes' disease. Differential diagnosis is no longer possible in later life, because the ultimate condition of the defective femoral heads is the same. Only in the hereditary cases is one able, by studying the capital epiphyses of the hip in childhood, to differentiate between the changes like those of Perthes' disease on the one hand, and micro-epiphysial dysplasia without necrosis on the other.
EARLY SKELETAL AND VASCULAR CHANGES IN RATS FED ON SWEET PEA (LATHYRUS ODORATUS) SEEDS
Authors: Amato V. P. , Bombelli R. 
Published: February 2018

The main findings in this experimental work on rats fed on lathyrus odoratus (sweet-pea) meal are as follows: 1. Growth is retarded. 2. The growth plate is disorganised and normal ossification at the metaphysis is interfered with. 3. The small blood vessels are seriously affected and probably contribute quite largely to the disorganisation and lack of calcification. 4. Alkaline phosphatase activity is increased. 5. Raising of the periosteum and laying down of new bone result in exostoses. The possible underlying etiology and the role of cement substance, endocrine factors and the blood vessels are discussed.
THE PATHOLOGY OF SLIPPED UPPER FEMORAL EPIPHYSIS
Authors: Rennie A. M. 
Published: February 2018

1. Epiphysial tilt commonly precedes slipping. 2. This tilt is due to a diminished or arrested growth from compression of the back of the epiphysial plate. 3. The stresses on the upper end of the femur are such that the upper femoral epiphysial plate is peculiarly liable to compression. 4. A primary abnormality of the cartilage of the epiphysial plate renders it susceptible to the effect of compression. 5. Because this abnormality is diffuse, deformities due to a similar pathology may be found elsewhere, notably in the spine.
