ALBERS-SCHÖNBERG'S DISEASE
Authors: Montgomery R. D. , Standard K. L. 
Published: February 2018

1. A type of bony sclerosis is described, occurring in nine members of a Jamaican family and resembling the more benign form of Albers-Schönberg's disease. The parents were consanguineous. Three of the patients developed facial palsy at the same age, and one had bilateral optic atrophy and proptosis. 2. Although radiological changes occurred of all grades of severity, certain features often described in this condition were lacking. In one child the onset of radiological changes was observed at the age of eleven years. 3. Serum studies showed increased alkaline phosphatase activity. 4. These features are discussed in the light of present-day knowledge and theory of the pathology of Albers-Schönberg's disease.
ANATOMICAL VARIATIONS AFFECTING THE SURGERY OF DE QUERVAIN'S DISEASE
Authors: Giles K. W. 
Published: February 2018

Attention has been drawn to the variations found in the anatomy of the tendons of the abductor pollicis longus and extensor pollicis brevis muscles as they lie in the first extensor compartment of the wrist. Such variations involve reduplication of the abductor pollicis longus tendon and more rarely the extensor pollicis brevis tendon. An accessory tendon may occasionally lie in a separate osseo-fibrous canal. It is not unusual to find the abductor pollicis longus and extensor pollicis brevis tendons lying in separate compartments, because an accessory fibrous septum is subdividing the first extensor compartment into two parts. Furthermore, the extensor pollicis brevis tendon may also lie in its own separate fibrous canal in the depths and the more distal part of this common compartment. Such variation could lead to two possible misinterpretations during the course of surgical decompression for de Quervain's disease and these misinterpretations could reasonably be linked with the failure rate for this particular operation. 1. The finding of the abductor pollicis longus and its accessory tendon in a single compartment (12 per cent of wrists in the series) after a limited surgical incision could be mistaken for the abductor pollicis longus and extensor pollicis brevis tendons. Such a mistake would lead to failure to decompress the extensor pollicis brevis. 2. A failure to identify the deeper-lying separate canal for the extensor pollicis brevis in the distal part of the compartment would again be responsible for failure to decompress the extensor pollicis brevis (14 per cent of wrists in this series).
THE VASCULAR CONTRIBUTION TO OSTEOGENESIS
Authors: Trueta J. , Little K. 
Published: February 2018

Throughout this work data have been gathered favouring the concept that the metaphysial vascular arrangement is primarily related to the process of enchondral ossification, and has very limited, if any, responsibility for the nourishment of the growth cartilage. The present evidence favours the suggestion that when the chondrocytes of the column have become too far separated from their source of nourishment (the epiphysial vessels) they and their surrounding matrix suffer changes which prepare them for the process of calcification. At least calcium and phosphate ions will be required for this to take place. The proximity of the vessel and also the fact that it is not isolated by a membrane at its very end suggests a profuse interchange of fluids with the surrounding area.
EXCISION OF THE TRAPEZIUM IN OSTEOARTHRITIS OF THE FIRST CARPO-METACARPAL JOINT
Authors: Murley A. H. G. 
Published: February 2018

1. The results of excision of the trapezium for degenerative changes in the first carpometacarpal joint are given. 2. The grip is usually permanently reduced by an appreciable amount, but functional power is improved by the absence of pain. 3. The patients most commonly affected, middle-aged women, usually derive appreciable benefit. 4. Recovery after operation often takes several months. 5. Interference with the radial nerve should be preventable by modification of the incision.
THE RADIOGRAPHIC DENSITY OF AVASCULAR BONE
Authors: Bobechko W. P. , Harris W. Robert 
Published: February 2018

1. Experimental avascular necrosis of the femoral head was produced in rabbits and the histological and radiographic changes were compared. 2. Avascular bone which was not re-ossified or altered in any way showed no change in density to x-rays. 3. Areas of avascular bone which were being repaired by the formation of appositional new bone showed an absolute increase in density in the radiographs. This is apparently due to simple increase in bulk of bone to be penetrated by the x-ray beam. On this basis, increasing density in radiographs of bone suspected of being dead is a sign of increasing re-ossification rather than of increasing necrosis. 4. Re-ossification of dead bone occurred rapidly in the absence of simultaneous resorption of necrotic trabeculae. It is thus suggested that the term "creeping substitution" is misleading and does not reflect accurately the histological findings, at least as they occur in rabbits.
FLEXION CONTRACTURES OF THE KNEE
Authors: Somerville E. W. 
Published: February 2018

1. The nature of flexion contractures of the knee joint is discussed. 2. It is suggested that division of the anterior cruciate ligament will help in the correction of the deformity when conservative methods have failed. 3. The results of the treatment of twelve such knees are mentioned and illustrative cases are described. 4. It must be emphasised that this method of treatment should be undertaken only when conservative methods have failed.
THE INFLUENCE OF THE NERVOUS SYSTEM UPON THE GROWTH OF BONES
Authors: Ring P. A. 
Published: February 2018

1. An experimental study of the effects of nerve and muscle lesions upon the growth of bone has been made. In each case animals were subjected to unilateral lesions in the hind limb, the other limb serving as a control. The growth of the tibia was measured by calculating the difference between the length of the bone on a radiograph at the beginning of the experiment and the length of the dried bone after necropsy. The weights of the dried bones were compared. 2. In the young rabbit simple exposure of the common peroneal nerve, or division of the sural nerve, produced no change in the growth rate of the tibia. Division of both peroneal nerves, producing paralysis of the muscles below the knee, led to lengthening of the affected tibia, and this lengthening persisted until maturity several months later. A similar lengthening was seen after division of the tendons around the ankle. In spite of this lengthening the tibia on the side of the operation was almost always lighter than its fellow. 3. In the puppy division of the anterior nerve roots supplying the hind limb produced a significant lengthening of the tibia of the affected limb three months after operation. No significant changes in limb length occurred after lumbar sympathectomy in the puppy. 4. The significance of these experimental nerve lesions has been considered together with recent observations upon the growth of bone in the presence of lower motor neurone lesions in the child. From this analysis it is suggested that the initial effect of paralysis is to produce lengthening of the affected bone. This lengthening is probably due to the hyperaemia of disuse. In the presence of persistent paralysis the growth of the limb is ultimately depressed. This depression is rarely seen in the experimental animal because the growing period is relatively short. The possible causes of this secondary depression of bone growth have been considered.
TRAUMATIC DISLOCATION OF THE HIP IN CHILDREN
Authors: Glass Alan , Powell H. D. W. 
Published: February 2018

1. A collected series of forty-seven traumatic dislocations of the hip in children is reported and reviewed in detail. 2. All were simple hip dislocations, and no child was included in whom there was any other injury to the affected joint. 3. All were posterior dislocations. 4. No anatomical predisposition was observed. 5. Significant complications occurred in fourteen children: avascular necrosis of the head of the femur in four, degenerative joint changes in three, premature epiphysial fusion in one and overgrowth of the femoral head in six. Study of the children with these complications revealed no common cause except the dislocation itself. 6. The injury responsible was often trivial. 7. The results suggest that it is harmless to bear weight four weeks after reduction.
RADIOTHERAPY FOR OSTEOGENIC SARCOMA
Authors: Tudway Robert C. 
Published: February 2018

1. Nine patients treated for osteogenic sarcoma by elective radical irradiation are reviewed. Five of the nine patients have survived for from three to fourteen years, but one patient has metastases. 2. These results are compared with those from primary amputation. 3. The importance of histological grading in prognosis is emphasised. 4. It is concluded that radical irradiation should be considered in place of primary amputation for osteogenic sarcoma in the upper limb.
PROGRESSIVE FIBROSIS OF THE VASTUS INTERMEDIUS MUSCLE IN CHILDREN
Authors: Hnêvkovský O. 
Published: February 2018

1. Twelve children are described in whom gradual limitation of knee flexion developed, without previous injury or inflammation. 2. Clinical and histological investigation showed progressive fibrous degeneration of the vastus intermedius and rectus femoris. 3. As the patella showed signs of retarded development a particular form of myodysplasia, probably congenital, may be supposed. 4. Conservative treatment always failed to stop the progress of this disease. 5. Surgical treatment (Bennett's method or an elongation of the ligamental apparatus of the intermedius muscle) was carried out in ten cases and gave good permanent results. Flexion remained possible only to the extent obtained at operation; rehabilitation gave no further improvement. 6. In the opinion of the author, these cases occur more often than is generally believed, but they are recorded under a different diagnosis and consequently are not submitted to rational treatment.
THE ASSESSMENT OF HAND FUNCTION AFTER PERIPHERAL NERVE INJURIES
Authors: Bowden Ruth E. M. , Napier J. R. 
Published: February 2018

1 . Power and precision grip (Napier 1956) were tested in 154 patients with nerve injuries. 2. The results are described, illustrated and discussed and it is suggested that these tests provide a simple, repeatable and objective method of assessing prehensile function of the hand as a whole.
INNOMINATE OSTEOTOMY IN THE TREATMENT OF CONGENITAL DISLOCATION AND SUBLUXATION OF THE HIP
Authors: Salter Robert B. 
Published: February 2018

1. The problem of instability of reduction in congenital dislocation and congenital subluxation of the hip has been studied and it has been concluded that the basic cause of this instability is the abnormal direction in which the entire acetabulum faces. 2. An operation, innominate osteotomy, has been designed to correct the abnormal direction of the entire acetabulum in children over the age of eighteen months. The principle of innominate osteotomy is redirection of the acetabulum so that the reduced dislocation or subluxation, which previously was stable only in a position of abduction and flexion, is rendered stable in the functional position of weight bearing. 3. The operative technique, and the pre-operative and post-operative management are described. 4. The indications for innominate osteotomy are outlined and the advantages of the operation are enumerated. 5. The early results of innominate osteotomy are very encouraging.
BONE GROWTH IN DIAPHYSIAL ACLASIS
Authors: Solomon L. 
Published: February 2018

1. The widespread deformities commonly associated with diaphysial aclasis have been studied in seventy-six patients. Apart from the adaptations of growth due to pressure by neighbouring exostoses, all the deformities of the tubular bones can be explained in terms of the same underlying factor–diminished length of the bones affected by the disease. 2. When the condition first manifests itself the future pattern of bone growth is completely unpredictable except in so far as it is known that the more actively growing ends of the long bones are the more severely affected in each case. It has also been shown in this series that, in general, the bones with the smallest cross-sectional area at the epiphysial plates (such as the ulna and the fibula) are the most severely shortened of all. 3. The cause of this disturbance of growth is still unknown, but there is an undoubted relationship between the presence of exostoses or thickening of the metaphysial region and shortening of the bone involved. 4. The phenomena of migrating exostoses and disappearing exostoses are also described and are shown to be examples of the normal process of bone modelling applied in special circumstances. 5. Although the importance of the cartilage-capped exostoses is not underestimated, it is hoped that this study will stimulate further work on what is probably the basic defect in this disease–namely, the disturbance of bone growth.
LONG SURVIVAL IN SOLITARY PLASMOCYTOMA OF BONE
Authors: Wright C. J. E. 
Published: February 2018

1. A case of solitary plasmocytoma of bone with survival for twenty-two years after amputation is described. 2. Recent follow-up of a previous tumour reported from this department by Stewart and Taylor in 1932 has shown survival for thirty-five years after amputation. 3. These two instances of long survival, together with three culled from the literature, substantiate the hitherto doubted concept of a true solitary plasmocytoma of bone.
INTRANEURAL GANGLION OF THE LATERAL POPLITEAL NERVE
Authors: Parkes Athol 
Published: February 2018

1. Eight cases of intraneural ganglion of the lateral popliteal nerve seen at operation within a period of six years are described. 2. In seven of these a pedicle was found arising from the superior tibio-fibular joint–it was probably present in the remaining case. 3. The essential step at operation is to find and extirpate the pedicle. 4. The implications of these findings are discussed.
PARTIAL SYNOVECTOMY IN THE TREATMENT OF TUBERCULOSIS OF THE KNEE
Authors: Wilkinson M. C. 
Published: February 2018

The infrequency of serious cartilage destruction in the joints of children makes it probable that the majority will recover with antibiotic and constitutional treatment alone, especially if a joint biopsy is performed. Synovectomy for children should therefore be reserved for those whose knees remain swollen and warm, even after antibiotic therapy, or whose range of movement does not show signs of returning. Exploration of such joints may show that pannus is wholly or partly covering the cartilage and that it is soft and pitted. Removal of the pannus allows better nutrition of the cartilage. The number of children who require arthrodesis in the future should be very small. Adults who respond well to antibiotic and constitutional treatment may also recover without surgery, except biopsy, but for patients with more severe disease the need for an alternative to arthrodesis exists. The choice between synovectomy–better called joint clearance –can often only be made after the joint has been opened. The choice between the two operations has always been fully discussed with the patient before the operation. The results enumerated in this paper suggest that arthrodesis may only need to be performed for patients with severe disease, often involving the bony articular surfaces, and that joints may recover function even when there has been partial destruction of cartilage.
FIBROUS DYSPLASIA OF BONE
Authors: Stewart Marcus J. , Gilmer W. Scott , Edmonson Allen S. 
Published: February 2018

1 . Twenty patients with fibrous dysplasia, confirmed histologically, are reported and discussed in regard to classification, etiology, pathogenesis and treatment. The various fibrous or fibrocystic lesions of bone are characterised briefly for purpose of contrast, and the position of fibrous dysplasia in this heterogeneous collection is suggested. 2. The classification of fibrous dysplasia based on the degree of skeletal involvement is used, and the diagnostic, therapeutic and prognostic implications of this classification emphasised. The authors endorse the opinion that fibrous dysplasia is a developmental defect. Clinical, histological and radiographic evidence is presented to point to the distinct evolution of the monostotic lesions, to which a positive and aggressive approach is recommended.
OSTEOTOMY OF THE NECK OF THE FIRST METATARSAL IN THE TREATMENT OF HALLUX VALGUS
Authors: Gibson John , Piggott Harry 
Published: February 2018

1. Correction of hallux valgus by spike osteotomy of the neck of the first metatarsal is described, and the results in eighty-two feet are presented. 2. A high proportion of satisfactory results can be obtained, but great care is needed in both selection and technique. 3. The ideal case is one of moderate deformity, without degenerative arthritis, and with symptoms referable to increased width of the forefoot; the operation should not be performed in cases with obvious degenerative change, nor when metatarsalgia is a prominent symptom. 4. It is important to displace the metatarsal head as far laterally as possible, and vital to avoid dorsal angulation or displacement. 5. It is suggested that enough is now known about the natural evolution of hallux valgus and the results of some operations for prophylactic surgery to be undertaken in carefully selected cases.
STUDIES IN THE TRANSPLANTATION OF BONE IV. The Immune Responses of Lymph Nodes Draining Second-set Homografts of Fresh Cancellous Bone
Authors: Burwell R. Geoffrey 
Published: February 2018

1. The response of the first regional lymph node to a homograft of fresh iliac cancellous bone inserted subcutaneously into the rabbit's ear three weeks after the introduction of a similar graft from the same donor into the same ear has been investigated in thirty rabbits. Fifteen rabbits which received second-set autografts of cancellous bone have also been studied. 2. The insertion of second-set homografts of fresh marrow-containing cancellous bone evokes an immune secondary response in the lymph nodes draining the grafts. 3. The increase in weight of the first regional lymph nodes on the side receiving second-set homografts is more rapid and of greater magnitude than that of nodes draining first-set homografts of cancellous bone. Second-set autografts evoke weight changes in the draining nodes similar to those in nodes draining first-set autografts of cancellous bone. 4. The histological changes which occur in the lymph nodes draining the second-set homografts (secondary response) are described and compared with those occurring in lymph nodes draining first-set homografts of cancellous bone (primary response). 5. In the primary response the distribution of large and medium lymphoid cells is throughout an activated sector of the cortex of the lymph node (Burwell and Gowland 1961), but in the secondary response these cells are found peripherally within the activated sector of the node. In both the primary and the secondary responses large and medium lymphoid cells are found in the medullary trabeculae of the lymph nodes. 6. The differences between the primary response of lymph nodes draining a tissue homograft (cancellous bone) and the primary response of lymph nodes draining classical antigens, and reported by other workers, are described. 7. Knowledge concerning the inflammatory response in the tissues of the host surrounding homografts of fresh cortical and cancellous bone implanted into animals previously sensitised to tissue from the respective donor is reviewed. 8. The late phase of new bone formation by homografts of fresh cancellous bone is discussed in the light of immunological studies.

Published: February 2018

1. The skeletal changes in endemic fluorosis are described from an area of the Punjab where the fluorine content of water and soil is very high. 2. A detailed description of a fluorotic skeleton is given, with its various anthropometric measurements. 3. The vertebral changes demonstrated the pathogenesis of the neurological complications observed in this condition.
DISPLACEMENT OF THE RUPTURED ULNAR COLLATERAL LIGAMENT OF THE METACARPO-PHALANGEAL JOINT OF THE THUMB
Authors: Stener Bertil 
Published: February 2018

1. The pathological anatomy of total rupture of the ulnar collateral ligament of the metacarpo-phalangeal joint of the thumb has been studied at operation in thirty-nine patients. 2. It has been found that the ligament, when ruptured distally (the most usual type) is often displaced so that the ulnar expansion of the dorsal aponeurosis–here referred to as the adductor aponeurosis–becomes interposed between the ruptured end of the ligament and the site of its attachment on the phalanx; the ligament gets folded over to a greater or lesser extent and the ruptured end sticks out beyond the proximal edge of the adductor aponeurosis. Such displacement of the ligament with interposition of the adductor aponeurosis was found in twenty-five of the thirty-nine cases. The ligament may also be displaced without the adductor aponeurosis being interposed (with a gap between the ruptured end and the site of itsattachment on the phalanx). 3. Variations in the pathological anatomy are illustrated by more detailed descriptions of nine cases. In one of these the adductor aponeurosis had got caught between the two surfaces of the joint, and in another the adductor aponeurosis was found ruptured as well as the ulnar collateral ligament. 4. On the basis of dissection studies on forty-two fresh post-mortem specimens, a rational explanation is given of the pathological anatomy. 5. The results of the present investigation on clinical and anatomical material provide a strong argument in favour of operative treatment for total rupture of the ulnar collateral ligament of the metacarpo-phalangeal joint of the thumb. 6. Aspects of diagnosis and operative technique are discussed.
