SURGICAL TREATMENT OF PULMONARY METASTASES FROM PRIMARY TUMOURS OF BONE
Authors: Sweetnam Rodney , Ross Keith 
Published: February 2018

1 . A series of twelve patients with solitary lung metastases from primary tumours of bone is reviewed. There were seven osteosarcomas, two chondrosarcomas, two fibrosarcomas and one malignant chondroblastoma. In each patient the lung desposit was resected. 2. Four patients have so far died from the disease. The average survival of the others since pulmonary resection is six years and seven months. 3. It is suggested that the results of pulmonary resection in carefully selected patients with solitary pulmonary metastases fully justify the procedure. 4. Careful investigation to ensure as far as possible that the metastasis is solitary, and a "waiting period" in case others should develop, are essential if unnecessary surgery is to be avoided. A waiting period of three months is recommended.
TARSAL TUNNEL SYNDROME
Authors: Lam S. J. S. 
Published: February 2018

1. The tarsal tunnel syndrome is a clinical entity and is probably more often encountered than is recognised. 2. The cause is unknown but is probably like that responsible for the carpal tunnel syndrome. Experimental evidence suggests that the sensory symptoms in both these conditions are due to localised ischaemia of the nerve within the fibro-osseous tunnels, and that later structural changes are responsible for motor paralysis. 3. Relief of symptoms is complete if decompression of the posterior tibial nerve is performed before the onset of motor involvement.
INTRA-ARTICULAR SURGERY FOR DEGENERATIVE ARTHRITIS OF THE KNEE
Authors: Insall J. N. 
Published: February 2018

1. The technique of the intra-articular surgery employed by the late Mr K. H. Pridie for osteoarthritis of the knee is described. 2. The results of sixty-two operations in sixty patients are analysed. The results in forty-eight knees (77 per cent) were pleasing to the patient. Forty knees (64 per cent) were rated as good at review. 3. The operation is most suitable for relatively active healthy people whose disability warrants a comparatively painful operation and lengthy rehabilitation. 4. The operation was most successful for relieving pain and improving stability. Functional improvement was less. 5. Results were remarkably permanent. The knees showed little tendency towards further deterioration. 6. Most of the bad results were associated with removal of the patella. A possible technical reason for this has been discussed.
UNRECOGNISED DISLOCATION OF THE HIP IN FRACTURES OF THE FEMORAL SHAFT
Authors: Helal B. , Skevis X. 
Published: February 2018

1. The combination of femoral shaft fracture with dislocation of the hip in the same limb has been recorded in eighty-one patients since 1823. 2. A further fourteen cases are reported. 3. In over half the cases the hip dislocation was diagnosed late or not at all, and this error has occurred more often in modern times. The reasons for this are outlined. 4. The diagnostic physical signs of hip dislocation in the presence of a femoral shaft fracture are described. 5. The mechanism, sequels and treatment of this combined injury are discussed.
OSTEOSARCOMA OCCURRING IN OSTEOGENESIS IMPERFECTA
Authors: Klenerman L. , Ockenden B. G. , Townsend A. C. 
Published: February 2018

1. Two girls with non-familial osteogenesis imperfecta who subsequently developed osteosarcoma of the femur are described. One is of special interest in that there were multiple bone metastases. 2. It is suggested that the tumours arose spontaneously and were not related to the underlying bone disorder. 3. Because of the relative frequency of hyperplastic callus formation in osteogenesis imperfecta it is most important that adequate biopsy material of any suspicious lesion is examined because the early clinical picture may be indistinguishable from a tumour.
FUNCTION AFTER RECONSTRUCTION OF SEVERED LONG FLEXOR TENDONS OF THE HAND
Authors: McKenzie A. R. 
Published: February 2018

1. The case notes of 140 patients with a total of 297 severed long flexor tendons in the thumb and fingers have been analysed. 2. Fifty-seven patients in whom tendon reconstructive surgery was performed have been examined and the results have been recorded by three methods. 3. Methods of assessing finger and tendon function are reviewed and discussed. Accuracy and precision in tendon repair should be followed by an accurate and precise evaluation of tendon, joint and finger function. 4. A method of assessing the function is described. This is expressed as a percentage of the function of the uninjured contralateral finger.
CHONDROMALACIA PATELLAE
Authors: Crooks L. Mackenzie 
Published: February 2018

1. It is suggested that abruptness of the condylar ridges on the femur plays a major role in the etiology of chondromalacia patellae. The medial condylar ridge is always abrupt in these cases, and indeed in many knees with no evidence of chondromalacia patellae. The lateral condylar ridge is rarely abrupt. 2. The short-term results of forty operations for reduction of femoral ridges in thirty-eight patients, with preservation of the patella in thirty-two cases, are satisfactory.
BLOOD SUPPLY OF THE HUMAN PATELLA
Authors: Scapinelli Raffaele 
Published: February 2018

1. A study has been made of the blood supply of the human patella. There are two main systems, one penetrating the middle third of the anterior surface and the other entering the lower pole of the bone behind the patellar ligament. 2. The relationship between these findings and the complication of avascular necrosis of the upper fragment of the patella after fracture is discussed. Forty-one cases of necrosis after operation have been studied and notes made on the pathological, clinical and radiological evolution of the condition. Whatever the severity of the ischaemic necrosis the prognosis was not substantially affected and good function was observed in all knees six months after injury. 3. The surgical implications of the vascular anatomy are discussed. It is pointed out that surgical intervention may damage the blood vessels entering the anterior surface of the bone and that circumferential repair of patellar fractures may strangle the vessels in their peripatellar course. 4. If removal of one-half of the patella after a transverse fracture is indicated, vascular studies indicate that the upper fragment should be removed.
CONGENITAL VERTICAL TALUS
Authors: Eyre-Brook Arthur L. 
Published: February 2018

1. Four cases of true congenital vertical talus are described; in three of the four cases there were other major deformities of the skeleton. All were treated by open operation; the operation sacrificed part of the substance of the navicular bone, which was placed between the forepart of the calcaneus and the head of the talus. 2. The results five to ten years after operation show that stable reduction was maintained without any further treatment. They suggest, however, that more of the navicular bone could have been removed or that the whole navicular might be excised, at least in the more severe deformities. 3. Congenital vertical talus resembles club foot (equino-cavo-varus) in that difficulty in reduction and in maintenance of the reduction results from the tension in the medial pillar of the foot. Easing of the tension can result in recurrence of the dislocation or, alternatively, a reversal of the deformity.
THE RECOGNITION AND TREATMENT OF CONGENITAL FLAT FOOT IN INFANCY
Authors: Silk F. F. , Wainwright Denys 
Published: February 2018

1. Eleven cases of congenital flat foot were studied, five of which are illustrated. 2. Ten of these cases were treated in infancy and followed for at least three years. In two cases the follow-up period was ten years and fifteen years. 3. An essential component of the deformity is equinus of the calcaneus, and treatment consisted of correction of the forefoot deformity by repeated manipulation, followed later by elongation of the calcaneal tendon and capsulotomy of the ankle. 4. The importance of recognising the deformity and beginning treatment in infancy is stressed.
CONGENITAL VERTICAL TALUS IN INFANCY
Authors: Harrold A. J. 
Published: February 2018

1. Eight cases of congenital vertical talus in infancy are reported. The principal differential diagnosis at this age is from talipes calcaneo-valgus. 2. The deformity is primarily a dorsal dislocation of the talo-navicular joint. 3. Closed reduction can be achieved if treatment begins at birth. Open reduction is indicated for the deformity uncorrected by the age of three months.
WRINGER INJURIES OF THE HAND
Authors: Matev Ivan 
Published: February 2018

1. In a series of seventy-one patients with wringer injuries of the hand three basic types of lesion were observed: a) denuding of part of or the entire hand, usually accompanied by avulsion of the distal phalanges; b) small lacerated wounds with wide detachment of surrounding skin and frequent fractures; c) multiple cut injuries of digits or the entire hand with skin avulsions. 2. Treatment was guided by the following principles: a) improvement of blood supply in regions of impaired nourishment; b) stable primary fixation of bones with Kirschner wires; c) primary wound closure through free skin grafting with maximal utilisation of available flaps. 3. Surgical technique as applied in various typical cases is outlined.
INLAY BONE GRAFTING FOR NON-UNION OF THE SCAPHOID BONE BY THE ANTERIOR APPROACH
Authors: Dooley B. J. 
Published: February 2018

Cancellous inlay bone grafting for delayed union or non-union of the scaphoid bone gives good results in most cases (Table IV). The operation is easy, does not require radiological control and does not damage the dorsal arterial plexus. The indications for the operation are twofold: firstly for patients complaining of disabling symptoms in the wrist joint with an established pseudarthrosis of the scaphoid bone, with neither arthritic changes nor severe avascularity of the proximal fragment; and, secondly, for delayed union in recent fractures despite adequate immobilisation. Union may still occur if conservative treatment is continued further, but because this may take up to eighteen months (during which time most patients would be unable to work), operation is a reasonable alternative. In this series two scaphoid fractures united after operation with some collapse of the proximal fragment. This probably resulted from removal of too much bone (preliminary to inlaying the graft) from an already small fragment with a poor blood supply. The operation can be performed even in the presence of a small proximal fragment and gave a satisfactory result in two out of three such cases.
HOMOTRANSPLANTATION OF ARTICULAR CARTILAGE AND ISOLATED CHONDROCYTES
Authors: Chesterman P. J. , Smith Audrey U. 
Published: February 2018

1. Techniques are described for homografting intact or partly digested hyaline cartilage or isolated chondrocytes on to cancellous bone in rabbits. 2. Material which had been cooled to and thawed from -79 degrees Centigrade either in the presence or absence of the protective substance dimethyl sulphoxide was grafted in the same way. In control experiments samples were boiled before grafting. 3. Necropsies were performed at intervals varying from two to twenty-six weeks later and the graft sites were removed, fixed and decalcified. Paraffin sections were stained histologically. 4. Freshly isolated chondrocytes or chondrocytes which had been frozen in the presence of dimethyl suiphoxide formed new matrix within two weeks and did not succumb to a homograft reaction. By the sixth week they had become aligned in columns surrounded by well stained matrix. There were signs oferosion by invading capillaries and osteoblasts, but no lymphocytes were seen. By the twelfth week invasion by trabeculae of newly formed bone was well advanced and by the twenty-sixth week the grafts were difficult to find although there had been no sign at any stage of an immunological reaction. 5. New matrix was also formed in homografts of hyaline cartilage which had been treated with papain or with papain and collagenase. After freezing in the presence of dimethyl sulphoxide, small areas ofthe grafts seemed to contain living cells which had formed new matrix. Other areas were disintegrating. 6. The homografts of intact cartilage showed a variety of appearances suggesting that the old matrix was gradually leached out and that chondrocytes liberated in vivo formed a new matrix. 7. Intact or partly digested cartilage which had either been frozen without dimethyl suiphoxide or boiled disintegrated and was rapidly replaced by bone after grafting. 8. When specimens of partly digested cartilage or isolated chondrocytes were homografted On to sites denuded of cartilage on the articular surface of the rabbit humeral head, nodules of fresh cartilage were formed. They were embedded in fibrous tissue derived, presumably, from marrow cavities opened up at the time of operation.
TRAUMATIC SPONDYLOLISTHESIS OF THE AXIS
Authors: Cornish Brian L. 
Published: February 2018

1. The clinical experience of fourteen cases of traumatic spondylolisthesis of the axis is described. 2. Evidence is presented which suggests that vertical compression and extension forces are frequently involved. 3. Treatment is based on recognition of the deforming force and its extent. 4. Primary treatment of unstable lesions by the coronally placed bone dowel of Barbour allows early stabilisation and long-term security. 5. The increased antero-posterior diameter of the axis explains the low incidence of spinal cord damage. 6. Skull traction is considered illogical in that it runs parallel in effect to the most deadly form of judicial hanging. 7. Secondary stability following injury may allow continuing force to fracture the spine at other levels. 8. The paradox of an extension injury between the second and third cervical vertebrae and a "flexion" injury at a lower level is discussed.
THE CONSERVATIVE TREATMENT OF BENNETT'S FRACTURE-SUBLUXATION OF THE THUMB METACARPAL
Authors: Pollen Andrew G. 
Published: February 2018

1. The treatment of Bennett's fracture is reviewed and the relative merits of conservative and operative treatment is considered. 2. A closed method of treatment is described and a series of thirty-one patients so treated is analysed. There were twenty-nine successful results. 3. It is urged that conservative treatment is the method of choice, and that operative measures should be reserved for the occasion when closed methods have failed.
THE RESULTS OF OPERATIONS FOR DISORDERS OF THE HIP CAUSED BY POLIOMYELITIS
Authors: Parsons D. W. , Seddon H. J. 
Published: February 2018

1. The treatment of contractures at the hip secondary to poliomyelitis by Soutter's muscle slide or by Yount's fasciotomy gives excellent results. So does high femoral osteotomy, but it is not superior to the other two and should therefore be kept in reserve as a supplementary operation for the completion of correction of a deformity so gross as not to be wholly remediable by division of the soft parts. 2. Subluxation of the hip occurs only if the paralysis comes on during the first eighteen months of life and is a product not of severe paralysis but of unbalanced and often slight weakness of muscles. Correction of the invariable valgus deformity of the femoral neck by osteotomy is followed by relapse; acetabuloplasty too is unreliable. The most promising remedy seems to be some form of acetabuloplasty combined with transplantation of an iliopsoas of adequate strength into the greater trochanter. The indications for arthrodesis are few, but the results of this operation are good. 3. In the few patients with abductor weakness and little else the dipping gait may be abolished by iliopsoas transplantation.
BILATERAL PROXIMAL RELEASE OF THE HAMSTRINGS IN CEREBRAL PALSY
Authors: Seymour N. , Sharrard W. J. W. 
Published: February 2018

1. In children with cerebral palsy and spastic paraplegia or tetraplegia with no fixed fiexion of the knees, tightness of the hamstrings may limit the stride, restrict passive straight leg raising and cause inability to sit up with the knees extended. 2. Nine such children have been treated by bilateral release of the hamstrings from the ischial tuberosity, with marked benefit in all patients.
THE RESULTS OF TRACTION INJURIES TO THE COMMON PERONEAL NERVE
Authors: White J. 
Published: February 2018

1. A series of six traction lesions of the common peroneal nerve in association with a severe adduction force to knee is described. 2. The reasons for failure of the nerve repair are discussed. 3. A new system of radiological marking of the anastomosis is described. 4. A less pessimistic view of the prognosis is taken than heretofore, and the management of the injury is discussed with a recommendation that a more conservative resection be done three months after the injury.
LIGATURE OF THE INTERNAL ILIAC ARTERY FOR MASSIVE HAEMORRHAGE COMPLICATING FRACTURE OF THE PELVIS
Authors: Horton R. E. , Hamilton S. G. I. 
Published: February 2018

1. Three cases of severe retroperitoneal haemorrhage complicating fractures of the pelvis are described. In two patients haemorrhage was immediately controlled by ligation of the internal iliac artery. The third patient died before the bleeding could be controlled. 2. Ligature of the internal iliac artery may be a life-saving measure when fracture of the pelvis is complicated by severe haemorrhage.
A NEW PROSTHESIS FOR DISARTICULATION AT THE HIP
Authors: Gillis Leon 
Published: February 2018

1. A prosthesis which is useful in unilateral disarticulations of the hip and highly advantageous in cases of bilateral disarticulation is described. 2. It makes use of the principle of a swing door and makes walking possible with the assistance of elbow crutches in cases of bilateral hip disarticulation and amelia.
ARTHROPLASTY OF THE KNEE BY THE WALLDLUS PROSTHESIS
Authors: Jones G. Blundell 
Published: February 2018

1. Forty-five arthroplasties of the knee with the Walldius prosthesis are reported in forty-two patients, thirty-seven with rheumatoid arthritis and five with osteoarthritis. 2. There has been no structural failure of the prosthesis. 3. Sepsis required removal of the prosthesis in three cases, but arthrodesis was obtained in two of the three. 4. Serious loosening of the prosthesis occurred in one case only. Varus deformity occurred in one patient. 5. Radiological evidence of some movement of the prosthesis was present in six other cases but this did not seem to affect function. 6. It is concluded that this operation has a place in the treatment of the more seriously disabled patient, but should not be used when heavy demands are likely to be made on the joint.
IMPACTED FRACTURES OF THE NECK OF THE FEMUR
Authors: Bentley G. 
Published: February 2018

1. Seventy patients with impacted fractures of the femoral neck treated from 1953 to 1965 have been reviewed. Forty-seven were treated conservatively and twenty-three by primary internal fixation. 2. The complications of both methods of treatment are recorded. 3. The prognosis following impacted femoral neck fractures is good. Seventy-nine per cent treated conservatively and 96 per cent treated by primary internal fixation had excellent or good results. 4. Primary internal fixation is the treatment of choice.
HARRINGTON'S INSTRUMENTATION AS A SALVAGE PROCEDURE FOR PSEUDARTHROSES IN SPINE FUSIONS FOR SCOLIOSIS
Authors: Berkin C. R. 
Published: February 2018

1. Twelve patients with suspected pseudarthroses in previous spine grafts were subjected to operation. 2. Correction of the curves was produced by Harrington's instrumentation at the sites of pseudarthroses, osteotomies and fractures. 3. A significant increase in stature was produced in all the patients. 4. Harrington's hooks were safely inserted into cavities cut in intact portions of previous grafts. 5. Most patients were able to leave hospital in less than four weeks. 6. Deliberate bending of the Harrington rods has not led to subsequent fracture of the rod. 7. A sliding scoliosis fusion frame is described. It reduces friction during correction and it reduces haemorrhage during surgery.
SPINAL STENOSIS, A CAUSE OF CAUDA EQUINA COMPRESSION
Authors: Schatzker Joseph , Pennal George F. 
Published: February 2018

1. The syndrome of spinal stenosis is due to compression of the cauda equina from structural narrowing of the lumbar spinal canal. 2. Patients with this syndrome present symptoms of cauda equina claudication or of unremitting bizarre back pain and sciatica. 3. The compression of the cauda equina is always posterior and postero-lateral and is caused by narrowing of the lateral recesses and of the dorso-ventral diameter of the spinal canal. 4. The diagnosis can be made only by myelography. The only form of successful relief of the nerve root compression in spinal stenosis is adequate lateral and longitudinal decompression.
THE PROXIMAL INTERPHALANGEAL JOINT
Authors: Kuczynski K. 
Published: February 2018

During flexion of the joint from the fully extended position the collateral ligaments soon become tight as they pass over the apex of angulation of the side margin of the head and remain tight as they move over more vertical plane of the side of the head. From measurements on the dissected fingers, from measurements on radiographs and from tracings of photographs of the proximal phalanx it was not possible to draw any definite conclusions about the sagittal cam effect comparable to those relating to the metacarpo-phalangeal joint. A few specimens exhibited some degree of this cam but most did not. This may be related to functional variations of individual fingers and requires more detailed study. If the joint is immobilised for some time in flexion with the collateral ligaments well below the apex of angulation, the slack volar part of the collateral aspects of the capsule with fibres running to the lateral and palmar tubercies of the middle phalanx and the dorsal fibres of the flexor sheath may become contracted. Shortening of the fibres of the lower part of the collateral portions of the capsule (A) and of the most dorsal fibres of the flexor sheath (B) was a constant finding. Curtis (1964) advocated excision of a portion of flexor sheath over the joint in dealing with flexion contracture. Dissection of two fingers affected by extension contracture suggests that it takes a long time to produce shortening of the soft and pliable more dorsal part of the capsule. It appears therefore that if immobilisation of the proximal interphalangeal joint cannot be avoided, it should be for as short a period as possible, with the collateral ligaments just riding over the apex of the side margin on the head when fibres A and B are only slightly slack. The results of immobilising the injured finger with the proximal interphalangeal joint flexed not more than 15 degrees might be compared with those after immobilisation with the joint more flexed. Splintage of the joint in extension was advised by Stewart (1962) on functional and clinical grounds. He noted the importance of flexion of the metacarpo-phalangeal joint and used the position of extension in all cases except those of: 1) gross damage leading inevitably to stiffness; and 2) division of flexor tendons or infection in the tendon sheath. It is suggested that in correction of contracture of the proximal interphalangeal joint caused by Dupuytren's affection it may be advisable to excise fibres A and B.
COMPLETE REPLACEMENT ARTHROPLASTY OF THE HIP BY THE RING PROSTHESIS
Authors: Ring P. A. 
Published: February 2018

1. A complete replacement arthroplasty of the hip is described in which both components are inherently stable. 2. The arthroplasty does not require the use of acrylic cement. 3. It is appropriate for the treatment of the severely arthritic hip in which arthrodesis is not indicated, and for the mobilisation of two stiff and painful hips at any age. 4. It can be performed on both sides at the same time. 5. It produces a stable, pain-free and mobile joint in a high proportion of cases, and has appeared not to deteriorate over periods of up to four years.
