A METASTASISING ADAMANTINOMA OF THE TIBIA
Authors: Morgan A. D. , MacKenzie D. H. 
Published: February 2018

1. The so-called adamantinoma of long bones is a clinico-pathological entity, the pathogenesis of which is still in doubt. The case for its being a synovial sarcoma showing epithelial differentiation is in our view unconvincing. 2. The tumour is slowly growing, and of low grade malignancy. Apparent cure has been effected in a third of the total cases recorded by amputation or resection of the diseased bone. 3. These means, however, have not prevented metastases to the lungs and skeleton in a similar number. 4. A case is presented in which a metastasis appeared in the chest twenty-two years after amputation of the leg. This was sensitive to telecobalt irradiation, and is the first case in which a distant metastasis has been proved microscopically.
PERSISTENT FOETAL ALIGNMENT OF THE HIP
Authors: Somerville E. W. 
Published: February 2018

1. The condition of persistent foetal alignment is discussed both as an entity and in its relationship to the development of a normal hip, and also to the varying degrees of congenital dislocation of the hip. A possible connection with osteoarthritis is also mentioned. 2. The secondary deformities to which it may give rise are discussed, and the way in which both primary and secondary deformities may be corrected is described. 3. The importance of estimating rotation with the hip in full extension is emphasised. 4. The results in eight patients so treated are mentioned.
TUBERCULOUS TENOSYNOVITIS
Authors: Pimm L. H. , Waugh W. 
Published: February 2018

1. Forty-four patients with tuberculous tenosynovitis have been reviewed. 2. The lesions (fifty-two in all) are classified and described according to their anatomical sites. 3. Particular reference is made to the natural history of the condition and the results of treatment. 4. Early and extensive excision of the affected tendon sheaths combined with the use of anti-tuberculous drugs is recommended.
THE USE OF TIBIALIS POSTERIOR AS A DORSIFLEXOR
Authors: Gunn D. R. , Molesworth B. D. 
Published: February 2018

1. Fifty-six cases of tibialis posterior transplant for drop foot are reported. 2. The results are known to be satisfactory in forty-nine of the fifty-six cases. 3. Serious complications have been few. 4. Re-education has been easy in the great majority of cases.
ARTHRITIS OF HIP COMPLICATING OSTEITIS PUBIS
Authors: Coates H. B. , Rose B. S. 
Published: February 2018

1. A case of arthritis of hip complicating osteitis pubis after retropubic prostatectomy is described. 2. It seems likely that bacterial infection was responsible in this case, although it was not proved. 3. Antibiotics did not appear to influence the course of the disease. 4. The progress of the disease was followed clinically and radiologically to its conclusion by natural healing with absorption of the femoral head, leaving a painless joint with good function.
THE ROLE OF ABDOMINAL PRESSURE IN RELIEVING THE PRESSURE ON THE LUMBAR INTERVERTEBRAL DISCS
Authors: Bartelink D. L. 
Published: February 2018

1. Since the publication by Bradford and Spurling in 1945 of The Intervertebral Disc, there has been argument about the figure of 1,600 pounds that they calculated as the load on each lower lumbar intervertebral disc when a person lifts a heavy load with the trunk flexed, especially since experiments have shown that intervertebral discs subjected to increasing pressures yield at values well below this figure. In the author's experiments the discs were destroyed by pressures ranging from 350 to 1,400 pounds, with a mean of 710 pounds. 2. It occurred to the writer that the spine is not necessarily the only structure in the body that can transmit pressure forces from the shoulder to the pelvis. A raised intra-abdominal pressure impacts a thrust under the diaphragm, which will be transmitted to the thoracic spine and the shoulders by means of the ribs. This thrust can take care of part of the lifted weight and thus decrease the load on the spine. 3. In experiments in which the intra-abdominal pressure was measured by means of a small balloon in the stomach it was found that the pressure rose proportionally with the amount of weight lifted. 4. It is suggested that the abdominal fluid ball can exert a longitudinal force only if there is no contraction of the longitudinal muscles (at least anteriorly). Electromyographic studies of the abdominal muscles during weight lifting showed that the transverse and possibly the oblique abdominal muscles contract, but not the recti. 5. It thus seems that the load on the intervertebral discs is not necessarily so great as Bradford and Spurling calculated, but can remain within safe limits. It is hard to give accurate figures for the amount of load that is taken off the spine in this way, but an estimate would put it at several hundred pounds. The importance of a reflex contraction of the abdominal wall during effort as a protective mechanism for the spine must therefore be appreciated. Voluntary contraction may also be called upon to increase the intra-abdominal pressure and so reduce the load on the discs. This is done by many weight lifters.
NON-UNION OF THE EPIPHYSIS OF THE LATERAL CONDYLE OF THE HUMERUS
Authors: Jeffery C. C. 
Published: February 2018

1. Thirteen cases of non-union of the epiphysis of the lateral condyle of the humerus were studied. Ten followed minor lateral luxations of the epiphysis; three were sequelae of open reduction and soft-tissue suture of major displacements. 2. In three cases in which non-union developed while the patient was under observation, union was secured after bone grafting by a technique described.
OBJECTIVE METHODS FOR DETERMINING THE FUNCTIONAL VALUE OF SENSIBILITY IN THE HAND
Authors: Moberg Erik 
Published: February 2018

1. It was observed clinically that tactile gnosis varies directly with the sudomotor function in the hand. 2. Two methods of fingerprinting were elaborated to register the sudomotor function, and consequently the tactile gnosis objectively. They are sensitive, simple to perform and suitable for clinical work. Their anatomical background, sources of error and relative value are discussed. 3. The correspondence between the sudomotor function, determined with these methods, and the tactile gnosis was established. This was done by, firstly, comparing the regions which did not perspire with the ones which became insensible on total denervation of a region of the hand; secondly, by examining the loss of function after nerve block; and thirdly, by comparing the tactile gnosis and sudomotor function in cases of residual median nerve defect. 4. These two qualities do not accompany each other in skin grafts. Grafts regain sudomotor function but never tactile gnosis. 5. A practical procedure for determining the functional value of the cutaneous sensibility in the hand is described. 6. Cases are related illustrating the usefulness of objective study of the sensibility in the hand.
PRIMARY BONE-FORMING TUMOURS AND THEIR RELATIONSHIP TO SKELETAL GROWTH
Authors: Price C. H. G. 
Published: February 2018

1. Analyses are presented of comparable groups of the two commonest bone-forming tumoursâosteochondroma and osteogenic sarcomaâderived from the following sources: Bristol Bone Tumour Register; British Empire Cancer Campaign Annual Report (1949); Stocks and Barrington (1925); Meyerding (1927); and Geschickter and Copeland (1949). 2. From this study, the following features emerge as characteristic and common to both tumours. 1) Both tumours are commoner in the male during the age periods 0-34 years, and over fifty years, with the possible exceptions of tumours of the humerus during early life and tumours of the pelvis. 2) The male preponderance is most marked for the appendicular long bones. 3) The male preponderance is greatest during the age period 15-34 years. 4) In the separate bones, these tumours tend to arise at a somewhat earlier age in the female. 5) In both sexes both tumours tend to arise at an earlier age in the bones of the upper arm and shoulder girdle than in those of the lower limb and pelvis. 6) Both tumours are related to an aberration of endochondral growth in length of bone. 3. The greater growth of the male, and differences in skeletal development in the two sexes, offer a simple and reasonably consistent explanation of these peculiarities and make it possible to discern the interplay of the three factors of age, sex and site of origin of the tumour. 4. From this concept it is possible to make a crude estimate of the factors of time and bulk of tissue which when combined may well account for the observed male preponderance of these tumours, and their anatomical distribution.
PARALYTIC CLAW HAND
Authors: Brand Paul W. 
Published: February 2018

1. The intrinsic paralysis that occurs in leprosy has been treated by the sublimis transfer of Stiles and Bunnell for the past nine years. Since 1951 300 hands have been operated upon, and 150 patients selected geographically have been followed up in this study. 2. The patients have been assessed by a standard method involving: 1) Measurement of range of movement of the interphalangeal joint (unassisted movement, assisted active movement and passive movement); 2) grasp index; and 3) photographs of each hand in six standard positions. 3. Assessment of the open handâThe Stiles-Bunnell procedure is effective in achieving a fully open hand: 73 per cent of the fingers scored good or excellent results. A defect in the operation is that it sometimes hyperextends the interphalangeal joint, producing an "intrinsic plus" hand. 4. Assessment of sequence of joint flexionâThe Stiles-Bunnell operation restores satisfactory mechanism of closure of the hand in 93 per cent of casesâthat is, the metacarpo-phalangeal joints flex before the interphalangeal joints. 5. The closedfist assessmentâAbout 30 per cent of patients had some defect in the complete closure of the fist after operation. In 5 per cent of cases the fingers did not reach the palm after operation. 6. ComplicationsâThe "intrinsic plus" defect is commonest in the best and most mobile hands. This is a late complication which gets worse in succeeding years. It can be corrected by Littler's operation together with a profundus tenodesis in the middle segment of the finger. Lateral deviation of fingers due to radial-side attachment of the transferred tendon can be avoided by ulnar-side attachment of the tendon used for the index finger. Bowstringing of the sublimis stump in the flexor sheath may be avoided by division of the sublimis at it insertion. Weakness of grasp and pinch from loss of sublimis may be avoided by using only one or two sublimis tendons split into several strands. The index finger sublimis should be left in position. 7. It is concluded that the sublimis transfer of Stiles and Bunnell is a very powerful corrective of intrinsic paralysis of the fingers. Its chief defect is that it is too powerful and produces the opposite deformity. For this reason the use of this operation should be restricted to fingers in which there is some limitation of passive extension. For fully mobile fingers an operation should be selected which does not remove the sublimis from its normal position.
INTERNAL FIXATION IN THE TREATMENT OF FRACTURES OF THE SHAFTS OF THE RADIUS AND ULNA IN ADULTS
Authors: Smith J. E. M. 
Published: February 2018

The place of internal fixation in the treatment of fractures of the shafts of the radius and ulna in adults is discussed, and the results in 130 fractures treated by internal fixation are reviewed. Non-union was found to be the most frequent and serious complication after internal fixation. The incidence of non-union can be greatly reduced if operation is delayed for at least one week, and preferably two to three weeks after injury. Evidence is presented to support the value of delayed operation in the promotion of union of fractures.
LUMBAR SPINAL OSTEOTOMY
Authors: Law W. Alexander 
Published: February 2018

1. The indications for correction of severe rigid kyphosis by lumbar osteotomy are described. 2. The fatal complications in a series of a hundred cases are listed. With more experience of this operation they should be considerably reduced. 3. Among the non-fatal complications the low incidence of recurrence of the deformity severe enough to require further operation is noteworthy.
COMPRESSION ARTHRODESIS OF THE ANKLE
Authors: Ratliff A. H. C. 
Published: February 2018

1. The results of compression arthrodesis of the ankle performed on fifty-five patients (four bilateral) are presented. 2. Fifty per cent of these ankles were immobilised for a total period of no more than eight weeks. 3. Bony fusion occurred in 91 per cent. 4. The subjective result was good or excellent in 88 per cent. 5. The theoretical disadvantages of the transverse incision are not serious in practice. 6. The best position for arthrodesis of the ankle is at, or close to, the right angle.
THE ACETABULAR INDEX
Authors: Laurenson Rae Duncan 
Published: February 2018

What is the present position? There is no doubt that the meaning of Kleinberg and Lieberman has been misconceived. With the passing of years their cautious conclusion concerning the acetabular index has been transformed into a firm conviction. Even so, it is apparent from the literature that the use of the acetabular index is a matter of controversy, and that, to a lesser degree, the normal values of the index are a matter of debate. It is concluded that the measurement is not an absolute index of a predisposition to congenital dislocation of the hip and cannot be divorced from other radiological signs. Nevertheless, so long as there is a feeling of uncertainty about the most reliable early signs of congenital dislocation of the hip, it would be folly to ignore a high acetabular index, especially in an infant over six months of age. It seems that to radiograph every infant at birth is not justified. The radiological signs at birth are not only unreliable because of problems of technique, but also equivocal because of the small size of the structures and the fact that they consist largely of cartilage. Until the radiographic technique is standardised it would be advisable to continue to regard 30 degrees as the upper limit of normal for the acetabular index in the newborn. To make recommendations concerning treatment is beyond the scope of this paper. Nevertheless it is worth stating that the presence of a high index alone is not necessarily regarded as an indication for immediate treatment. But an infant found to have a high acetabular index should be kept under close observation and should be thoroughly examined at regular intervals before the beginning of full weight bearing.
THE VASCULAR ANATOMY OF THE SPINE AND ITS RELATIONSHIP TO PYOGENIC VERTEBRAL OSTEOMYELITIS
Authors: Wiley A. M. , Trueta J. 
Published: February 2018

1. Vascular anatomical studies of the spine are described and the possibility of spread of infection from pelvis to spine through the paravertebral venous plexus is discussed. 2. Though a venous route does exist, our studies do not support the supposition that infection is likely to spread by this route; nor is there any clear clinical, pathological or anatomical evidence that such spread occurs. 3. Nineteen cases of pyogenic osteomyelitis of the spine are recorded, six of which followed urinary infections. The condition is compared with osteomyelitis as it occurs in the other bones of adults.
RADIOACTIVE ISOTOPES IN FRACTURES OF THE NECK OF THE FEMUR
Authors: Arden G. P. 
Published: February 2018

1. A method is described for measuring blood flow to the head of the femur after fracture of the femoral neck, by estimation of the rate of uptake of radioactive phosphorus. 2. Of one hundred cases investigated the readings in fifteen were incomplete, and in seventeen were unreliable. Reasons are given for discarding the latter seventeen cases. After two years seven patients had died, leaving sixty-one available for analysis. 3. The results in sixty-one surviving patients with a follow-up of not less than two years are analysed. In twenty of these radioactivity was measured by bone sampling and in forty-one by direct readings with a needle counter. 4. The twenty-one intertrochanteric fractures studied were used as controls. In these the P32 ratio varied from 0·4 to 3·0. Union occurred in all patients and none developed avascular necrosis. 5. Of the forty patients with displaced fractures of the femoral neck twenty-eight showed a low P32 ratio. In twenty-three of these (82 per cent) the fracture united. 6. Twelve patients with fractures of the femoral neck showed a borderline or abnormal P32 ratio. In ten of these there was subsequent avascular necrosis or non-union. 7. The possible reasons for the discrepancy between expected and actual results are discussed. 8. Almost 40 per cent of the cases investigated had to be abandoned because of technical faults and in one-fifth of the remaining cases the expected results failed to agree with the clinical results. The method of investigation is therefore not of much practical value at the present time. Improvements in apparatus and technique might make the method more reliable and more useful.
FAMILIAL EPIPHYSIAL DYSPLASIA OF THE LOWER LIMBS
Authors: Weinberg H. , Frankel M. , Makin M. , Vas E. 
Published: February 2018

1. A family of six generations, consisting of 114 members affected by epiphysial dysplasia of the lower extremities, is described. 2. Twenty-two males and twenty-three females were affected, while thirty-two males and thirty females were unaffected. Seven members of the family could not be traced. 3. Variations from Fairbank's description of dysplasia epiphysialis multiplex are discussed. In the family here reported the lower limbs only were affected and the severity of the disease was very variable. 4. Long term follow-up studies are presented.
CHARNLEY STABILISATION OF THE HIP
Authors: Piggot J. 
Published: February 2018

1. Ninety-one patients with Charnley stabilisation have been reviewed. 2. The patients' ages ranged from fifteen to seventy-eight, with an average of fifty-seven years. 3. Patients have been followed up for at least one year, the average period being almost three years. 4. Early complications included low grade pyrexia (33 per cent), femoral thrombosis (10 per cent) and pulmonary embolus (5 per cent). 5. Fifty-four per cent of patients had no backache, 36 per cent had slight and 10 per cent had troublesome backache. 6. Sound bony fusion occurred in 72 per cent, unsound union in 19 per cent and stress fracture in 9 per cent. 7. Stress fracture and unsound union occurred most frequently in those over sixty years of age. 8. In eighteen patients under fifty there was one unsound fusion and no stress fracture.
McMURRAY OSTEOTOMY
Authors: Robins Robert H. C. , Piggot James 
Published: February 2018

1. Nine out of ten patients who undergo McMurray osteotomy may expect lasting relief of pain. Seventy-five per cent should have a satisfactory functional result. It is rare for a patient to be made worse. 2. Osteoarthritis of the hip and ununited fracture of the femoral neck are good reasons for operation; avascular necrosis after fracture is not. 3. Internal fixation shortens the time in plaster and in hospital, and reduces the incidence of stiffness of the knee. 4. The common observation that the joint space may be increased after osteotomy is due often to the altered position of the femoral head. Occasionally there occurs a true increase in joint space, presumably indicating regeneration of articular cartilage, and an accompanying regression in the changes of osteoarthritis.
ANTERIOR DISLOCATION OF THE ULNA AT THE INFERIOR RADIO-ULNAR JOINT
Authors: Rose-Innes A. P. 
Published: February 2018

1. Two cases are reported of the uncommon condition of simple anterior dislocation of the head of the ulna at the inferior radio-ulnar joint. 2. The literature concerning the condition and its treatment is reviewed. 3. The mechanism of the inferior radio-ulnar joint is discussed with particular reference to the function of the triangular fibrocartilage. 4. The mechanism of injury is discussed and a new idea of this mechanism is put forward.
CHONDROMYXOID FIBROMA OF BONE
Authors: Hutchison J. , Park W. W. 
Published: February 2018

1. A case of chondromyxoid fibroma of the tibia is reported. 2. Initial removal by curettage was followed by regrowth of residual foci; these were removed by a second curettage three years later. Re-examination after a further three years shows no evidence of regrowth, and suggests that cure has been achieved. 3. Some histological features of the neoplasm are briefly described.
SUPPURATIVE ARTHRITIS OF INFANCY
Authors: Lloyd-Roberts G. C. 
Published: February 2018

1. Attention is drawn to the powers of resistance of the growing ends of bones in suppurative pyogenic arthritis of the knee and hip in infancy. 2. It is emphasised that a translucent zone in the radiograph does not necessarily mean that this part of the bone, epiphysial cartilage or plate is destroyed. 3. Diagnostic criteria are described to confirm that cartilage or decalcified bone has survived the infection in the knee joint. 4. The prognosis for the knee joint is discussed. 5. The hip joint presents greater difficulties in diagnosis and greater issues are at stake. It is recommended therefore that the hip joint be manipulated or explored if the radiograph and the physical signs suggest that destruction of the joint has either caused dislocation or has so damaged it that dislocation is likely to occur in the future. In favourable cases stability may be restored to the hip. In the others a diagnosis of irreparable destruction is established and the surgeon is satisfied that an opportunity to help the patient has not been lost.
EXPERIMENTAL PROGRESSIVE SCOLIOSIS IN THE RABBIT
Authors: Langenskiöld A. , Michelsson J.-E. 
Published: February 2018

1. By unilateral resection of the posterior ends of the sixth to eleventh ribs including the costal parts of both costo-vertebral joints, progressive scoliosis can regularly be provoked in young rabbits. Rotation of the vertebrae is prominent in the experimental deformity. 2. Although severe progressive scoliosis can be provoked by a surgical procedure we do not yet know the deforming forces which are released by the operation, but the way lies open for accurate studies on these factors. 3. It seems possible that studies on experimental progressive scoliosis may provide us with new methods to counteract or cure scoliosis in children. The goal is a means to reverse the deforming forces during growth so that the child's spine is straight when growth ceases.
