Purpose To improve the care of survivors of head and neck cancer, we developed the Head and Neck Survivorship Tool: Assessment and Recommendations (HN-STAR). HN-STAR is an electronic platform that incorporates patient-reported outcomes into a clinical decision support tool for use at a survivorship visit. Selections in the clinical decision support tool automatically populate a survivorship care plan (SCP). We aimed to refine HN-STAR by eliciting and incorporating feedback on its ease of use and usefulness. Methods Human-computer interaction (HCI) experts reviewed HN-STAR using think-aloud testing and the Nielsen Heuristic Checklist. Nurse practitioners (NPs) thought aloud while reviewing the clinical decision support tool and SCP and responded to an interview. Survivors used HN-STAR as part of a routine visit and were interviewed afterward. We analyzed themes from the feedback. We described how we addressed each theme to improve the usability of HN-STAR. Results Five HCI experts, 10 NPs, and 10 cancer survivors provided complementary usability insight that we categorized into themes of improvements. For ease of use, themes included technical design considerations to enhance user interface, ease of completion of a self-assessment, streamlining text, disruption of the clinic visit, and threshold for symptoms to appear on the SCP. The theme addressing usefulness was efficiency and comprehensiveness of the clinic visit. For each theme, we report revisions to HN-STAR in response to the feedback. Conclusion HCI experts provided key technical design insights into HN-STAR, whereas NPs and survivors provided usability feedback and clinical perspectives. We incorporated the feedback into the preparation for additional testing of HN-STAR. This method can inform and improve the ease of use and usefulness of the survivorship applications.
PRESSURE AT THE CERVICO-BRACHIAL JUNCTION
Authors: Telford E. D. , Mottershead S. 
Published: February 2018

1. The causes of pressure on the neuro-vascular bundle of the upper limb are many and varied. No one cause such as clavicular pressure can explain all cases. 2. Costo-clavicular pressure is not possible when there is a normal first rib and a normal thoracic outlet, but it is certainly a factor when the costo-clavicular interval is narrowed by the presence of a large cervical rib or an abnormal first thoracic rib. Clavicular pressure can act only during retraction and abduction, not in depression of the shoulder. 3. Temporary alterations in the radial pulse on movements of the shoulder in normal individuals are due to causes distal to the clavicle and have no relation to costo-clavicular pressure. 4. While irritation of sympathetic nerve fibres may explain the majority of cases of thrombosis, there are others in which clotting occurs in an aneurismal dilatation produced by pressure between the clavicle and the abnormal costal element. It is likely that the thrombosis occurs in an aneurism which has been present for some length of time. The cause of the aneurismal dilatation may be vaso-motor paralysis of a segment of the artery, ending distally at a point where a fresh intact leash of nerves is relayed to the vessel. 5. The importance of the scalenus anterior syndrome has been over-emphasised. If operative treatment is limited in all cases to anterior scalenotomy the results will be disappointing. 6. If operation is advised it should be performed without rigid and preconceived ideas, through an adequate incision, and with exploration wide enough to allow thorough investigation of the cause of pressure.
THE MOVEMENTS OF BONES AND JOINTS
Authors: MacConaill M. A. 
Published: February 2018

1. Muscles acting upon any joint can be divided into two principal groups: muscles of displacement or spurt muscles, and muscles of stabilisation or shunt muscles. 2. Muscles which arise far from the joint are spurt muscles; those which arise near it are shunt muscles. 3. The fibrous tendon sheaths are joint-stabiising mechanisms. 4. The lumbrical and interosseous muscles are muscles of stabilisation of the digits. 5. The arrangement of the musculature is such as to ensure a constant pressure across the joint cavity during rest or uniform movement. The necessary centripetal force during movement is supplied mainly by the shunt muscles. 6. Experiments are described to illustrate these observations.
INTERMITTENT CLAUDICATION
Authors: Boyd A. M. , Ratcliffe A. Hall , Jepson R. P. , James G. W. H. 
Published: February 2018

1. A description is given of historical discoveries relating to intermittent claudication. Various theories that have been advanced are discussed. A hypothesis, based on the work of Lewis, is elaborated. 2. A classification of obliterative arterial disease is outlined. The three groups that are distinguished are: primary thrombosis of the popliteal artery; juvenile obliterative arteritis; and senile obliterative arteritis. 3. The methods adopted for assessment of the severity of disease, including study of the clinical features, arteriographic findings, results of novocain infiltration and examination of the patient on a walking machine, are reported. 4. Methods of treatment by Buerger's exercises, contrast baths, intermittent venous occlusion and suction pressure; by lumbar ganglionectomy ant paravertebral block with phenol; by vitamin E (Î±-tocopherol) therapy; by treatment with thiouracil antistin; by internal popliteal myoneurectomy and division of the external popliteal and posterior tibial nerves; and by tenotomy of the tendo Achillis, are discussed. 5. It is concluded that tenotomy of the tendo Achillis should replace myoneurectomy in Type 3 cases where the blood supply is so far reduced that vascular stability cannot be achieved, and that it might apply in Type 2 cases in which there is persistent pain at a steady level. 6. The results of treatment in 276 patients with intermittent claudication are recorded.
THE PAINFUL SHOULDER Review of One Hundred Personal Cases with Remarks on the Pathology
Authors: Withers R. J. W. 
Published: February 2018

1. In a series of one hundred personal cases of "painful shoulder" rupture of the musculotendinous cuff was proved by operation in eighteen cases and was presumed in eight further cases, namely, in about one quarter of the series. 2. Of the eighteen cases treated by operation through the transacromial approach, perfect results were obtained only in four. The other results were unsatisfactory. In five, movement was good but there was pain or weakness of the limb. In nine the condition was unaltered or made worse. 3. Conservative treatment of traumatic lesions of the supraspinatus tendon is therefore advocated. The advisability of rest of the shoulder joint in an abduction splint for five or six weeks is stressed. Operative exposure, through a transacromial approach, is recommended only when conservative measures have failed. 4. When there is rupture of the cuff there is evidence that simple longitudinal suture of the gap after freshening of the margins is likely to give better results than attempts to suture the medial end of the rupture to the greater tuberosity. Most ruptures have a longitudinal extension of the initial transverse tear, and direct suture of the medial edge of the gap to the greater tuberosity may lead to shortening of the tendon and interference with its function. 5. Ruptures of the supraspinatus tendon may cause no symptoms, lead to complete loss of function, or cause a painful arc of movement during mid-elevation. The clinical state depends upon whether or not the condition of the ruptured tendon is causing pain, and whether the other short rotator muscles of the shoulder can compensate in tensor and fixator actions for the loss of action of the supraspinatus. 6. Capsulitis is a convenient term by which to describe inflammatory lesions of the capsule and bursae around the shoulder joint. The initial stage of irritative capsulitis may develop to the later stage of adhesive capsulitis. Differentiation is important because treatment in the first stage is by rest, and in the second by manipulation and exercise. 7. The subdeltoid bursa is the "peritoneum" of the spinatus tendons; like the peritoneum it shares the pathology of the organs it protects and is itself seldom the site of primary pathological processes. 8. The management of the "frozen shoulder," whether loss of movement is protective or adhesive, calls for time and patience but the ultimate outlook is good.
SHOULDER PAIN With Particular Reference to the "Frozen" Shoulder
Authors: Simmonds F. A. 
Published: February 2018

1. The "frozen" shoulder syndrome is due to an inflammatory lesion in the musculotendinous cuff invoked by a local area of degeneration. 2. The available evidence suggests that the primary site of the degenerative lesion is in the supraspinatus tendon. 3. Other causes of shoulder pain which must be differentiated from "frozen" shoulder are peritendinitis of the long head of biceps, degeneration or tears of the supraspinatus, and calcified deposits in the supraspinatus. 4. An explanation of the pathogenesis of lesions of the musculo-tendinous cuff is submitted in which the different types of clinico-pathological syndrome are correlated. This hypothesis is in accord with the experimental, clinical and operative findings.
ARTERIOGRAPHY IN BONE TUMOURS
Authors: Dos Santos Reynaldo 
Published: February 2018

1. Serial arteriograms show not only the anatomical distribution of blood vessels but also the functional state and activity of the peripheral circulation. The technique is of value in the diagnosis of tumours of soft tissues and bone, and particularly in the differential diagnosis of bone tumours from chronic osteomyelitis. It may be used to assess the response of malignant bone tumours to treatment by irradiation. 2. In malignant bone tumours, serial arteriograms show irregular formation of new vessels of uniform diameter, "blood pools," and increased rapidity of flow from the arterial to the venous systems. 3. In osteoclastomas there is new vessel formation and an appearance of "blood pools," but less rapid filling of the veins. In simple tumours there is no new formation of vessels. The tumour itself is often relatively avascular. 4. In osteomyelitis there is no new formation of vessels but only dilatation of existing vessels. The vessels retain their orderly and regular arrangement of successive branches of gradually decreasing diameter.
TRANSITORY EOSINOPHILIA LOCALISED IN THE NEE JOINT AFTER PNEUMARTHROGRAPHY
Authors: Murray R. C. , Forrai ElemeÌr 
Published: February 2018

1. Study of 200 cases investigated by pneumarthrography has shown that the introduction of air or oxygen into the knee joint is followed by a specific reaction characterised by transient localised eosinophilia in synovial membrane and synovial fluid. 2. Complications after meniscectomy seem to be more frequent when operation is performed during the phase of eosinophil reaction. 3. The significance of these observations has been discussed in relation to other causes ofeosinophilia and it is suggested that this method of local production of eosinophils may be of experimental importance.

One hundred and sixty-four cases of intramedullary nailing of the long bones have been studied with special reference to the difficulties and complications encountered. There was one death not attributable to the method. Two cases of pulmonal fat embolism and one case of thrombosis occurred, all in fractures of the femur. The lessons we have learned from our mistakes can be summarised as follows: 1 . The method requires technical experience and knowledge and is not suited to inexperienced surgeons or surgeons with little fracture material at their disposal. 2. Intramedullary nailing should only be used in fractures to which the method is suited. In general, comminuted fractures or fractures near a joint are unsuitable. 3. Open reduction is preferable to closed methods. 4. The nail should never be driven in with violence. It should be removed and replaced with a new one if difficulty is encountered when inserting it. 5. In fractures of the femur the nail should be driven in from the tip of the trochanter after careful determination of the direction. 6. The nail should be introduced only to the level of the fracture before exploring and reducing the fracture. 7. Distraction of the fragments must be avoided. 8. If the nail bends it should be replaced by a new one, at least in femoral fractures. 9. If union is delayed, the fracture should be explored and chip grafts of cancellous bone placed around it. 10. Improvised nails or nails which are not made of absolutely reliable material should never be used. 11 . Make sure that the nail is equipped with an extraction hole for removal.
THE MONTEGGIA FRACTURE WITH POSTERIOR DISLOCATION OF THE RADIAL HEAD
Authors: Penrose J. H. 
Published: February 2018

1. The posterior Monteggia fracture usually conforms to a typical pattern. 2. Its incidence is greatest among middle-aged women. 3. The mechanism of the injury is probably similar to that of the dislocated elbow. Excessive rotation of the forearm plays no part in its production. 4. Internal fixation of the ulna combined with excision of the whole radial head, or of its detached segment, is suggested as the treatment of choice. 5. The functional results after operation are excellent, but some slight permanent restriction of movement is to be expected.
STUDIES OF PAGET'S DISEASE (OSTEITIS DEFORMANS)
Authors: Lake Max 
Published: February 2018

Sarcoma complicating Paget's disease is uncommon; ninety-five cases have been collected and seven further cases are now reported. Sarcoma probably complicates less than 2 per cent of all cases of Paget's disease. There is a relatively high incidence in males, especially in the sixth decade, whereas bone sarcoma over the age of fifty years without osteitis deformans is rare. Injury is prominent in the history of many cases. Comparison of Paget's sarcoma, "ordinary" bone sarcoma and the bones affected by uncomplicated osteitis deformans reveals some important differences. As to the type of tumour, osteogenic sarcoma is the commonest, but fibrosarcoma and round-cell sarcoma are also frequent. The serum phosphatase is a most useful prognostic guide in a disease with a generally poor prognosis. Magnesium metabolism in relation to bone sarcoma requires further study. Prophvlaxis is based on a clinical suspicion of this complication in Paget's disease, and measures are outlined which may be of assistance. Sarcoma in Paget's bone is highly lethal, but Nature in striking down these old people may have provided us with facts which will ultimately solve problems common to all sarcomas of bone.
EXPERIMENTAL INVESTIGATIONS INTO THE PHYSICAL PROPERTIES OF THE INTERVERTEBRAL DISC
Authors: Virgin W. J. 
Published: February 2018

1. The intervertebral disc is an organic viscous elastic structure capable of maintaining very great loads without disintegration. 2. Recovery of the disc after deformation depends upon: a) the imbibition of tissue fluid by the disc, b) the removal of the deforming force. Complete recovery is modified by the duration of the force. 3. Factors that interfere with the elasticity of the disc are: extreme youth (immaturity of the disc), chronic wasting diseases (general nutritional disturbance), and local pathological changes in the bodies of the vertebrae which interrupt or damage its blood supply. The intervertebral disc reaches its greatest state of efficiency in adult lifeâthat is, when the nucleus pulposus has disappeared as an entity. The function of the disc appears not to depend upon the presence of the nucleus : rather does the presence of the nucleus indicate immaturity of the disc. 4. The highly resilient elastic nature of the vertebral column is provided by the intervertebral discs, which constitute one-third of the whole length of the column. 5. The imbibition of fluid requires further investigation. It appears that from lacunae in the adjacent bodies finger-like pockets dip into the discs and that fluid passes through the lining membrane of these pockets.
EXPERIMENTAL INCISION OF THE INTERVERTEBRAL DISC
Authors: Smith J. W. , Walmsley R. 
Published: February 2018

1. The normal anatomy of the intervertebral disc of immature rabbits is described. 2. An account is given of the changes that occur after an operative incision in the ventral part of the intervertebral discs of rabbits which allowed the escape of the nucleus pulposus. The account is based on observations made on fifty-five young animals killed at intervals during the twenty-five months after operation. 3. The superficial part of the wound in the annulus heals rapidly by active fibrosis. Thereafter there is a chondrification of the ventral region of the disc, followed by ossification. A prominent bony ridge ultimately ankyloses the vertebrae adjoining the disc. 4. The site of the nucleus pulposus is eventually occupied by a dense pad of fibrocartilage. A tongue of this tissue projects into the deep median part of the wound which remains unhealed. 5. A hypothesis is submitted regarding the mechanism of rupture of the annulus fibrosus and prolapse of the nucleus pulposus in man; this hypothesis is based in part on the observations of lesions in discs not subjected to operation.
REPOSITION WITH ARTHROPLASTY FOR CONGENITAL DISLOCATION OF THE HIP IN ADULTS
Authors: D'AubigneÌ R. Merle 
Published: February 2018

Arthroplasty, with normal or nearly normal reposition, is possible in most old congenital dislocations of the hip in young adults. Reposition is possible even in very high dislocation, but it is difficult or impossible in aged patients and when arthritic changes have taken place. The reduction equalises the length of the extremities in unilateral cases, but makes operation on both sides necessary in bilateral cases. Post-operative complications may be largely avoided by a good technique and careful post-operative treatment. Stability is good, and consequently the limp is generally reduced. Mobility is as a rule sufficient, though often less than before operation when the hip was normally or excessively mobile. Pain is very often relieved or greatly reduced, but walking is generally limited. Even if the radiographic appearance of the hip is almost normal, the functional result may be imperfect. This assessment is probably pessimistic, for two reasons: first, patients operated on are still improving; second, the improved technique of the later operations should give better results. Nevertheless, arthroplasty with reduction should be proposed to patients only suffering severe functional disability.
DEPOSITION OF CALCIUM SALTS IN THE MEDIAL LIGAMENT OF THE KNEE
Authors: Lamb Douglas W. 
Published: February 2018

1. Two cases of deposition of calcium in the medial ligament of the knee are described. Pain was a prominent feature in both. 2. A review of the literature suggests this is an uncommon condition. 3. The condition closely resembles supraspinatus calcification, and the etiology is probably similar. 4. Both cases were treated by operation, with complete relief of symptoms.
OSTEOPOROSIS AND EPIPHYSIAL ARREST IN JOINT TUBERCULOSIS
Authors: Sissons H. A. 
Published: February 2018

Amputation or post-mortem specimens from eight cases of joint tuberculosis, with immobilisation changes in bone, have been studied by fine-detail slab radiographs and subsequent histological examination. The findings in three of these cases are presented in detail. The immobilisation changes take the form of a true osteoporosis, which is strikingly focal in nature. In the adult the sites of most marked involvement include the subcortical bone adjacent to articular surfaces and the bone in the neighbourhood of the obliterated epiphysial plates. Areas of permanent change in bone structure may result, although commencing "repair" is seen in the form of newly developed bone trabeculae in the osteoporotic areas. In one case, where immobilisation occurred at an early age, changes in the growing epiphysial plates were produced in addition to osteoporosis. This is correlated with the known susceptibility of growing epiphysial cartilage to a wide variety of damaging agents. Radiologically, it is important to discriminate between these immobilisation changes and the bone destruction which might be produced by extension of the tuberculous lesion itself.
RESULTS OF TREATMENT OF INFECTIONS OF THE HAND
Authors: Scott J. C. , Jones B. V. 
Published: February 2018

1. A series of 1,211 cases of infection of the hand and fingers is reviewed. Of the 1,066 which required operation about two-thirds were treated by excision and suture, and the results in these cases are analysed. 2. The criterion of success was per primam healing in seventeen days or less, and 54 per cent of the cases treated by this method (excluding paronychiae) fulfilled this criterion. 3. The causes of failure are discussed. 4. It is concluded that excision and suture is the method of choice in well localised infections, but that it should be avoided in diffuse infections and in some cases with sinuses. Its use is unnecessary in trivial infections.
FAMILIAL PAGET'S DISEASE WITH EARLY ONSET
Authors: Irvine R. E. 
Published: February 2018

1. A father and two daughters suffering from Paget's disease are described. 2. The father's case is of special interest because he developed a malignant osteoclastoma of the mandible. 3. In the two daughters the condition was notable for the fact that in each case it began at the age of eighteen in the jaws, and led to the development of osteoporosis circumscripta of the skull. 4. The relationship between Paget's disease and osteoporosis circumscripta, and the age incidence and familial incidence of Paget's disease, are discussed.
OSTEOPATHIA STRIATAâVOORHOEVE'S DISEASE
Authors: Hurt R. L. 
Published: February 2018

1. A case is reported which shows the typical features of osteopathia striata in all the long bones and probably in the pelvis, with the features of osteopetrosis in the skull and ribs. 2. The occurrence of longitudinal striation in osteopoikilosis and osteopetrosis is described, and the possible relationship between these two diseases and osteopathia striata is discussed. 3. The differential diagnosis is indicated.
THE ROLE OF SYMPATHECTOMY IN THE TREATMENT OF CAUSALGIA
Authors: Barnes Roland 
Published: February 2018

1. Forty-eight cases of causalgia are reviewed and the clinical features are briefly described. 2. Multiple nerve injuries are common and the pain is often associated with all the injured nerves. In the upper limb there was always an incomplete lesion of the lower trunk or medial cord of the brachial plexus, or of the median nerve. In the lower limb there was always an incomplete lesion of the medial popliteal division of the sciatic, the medial popliteal, or the posterior tibial nerve. These nerves carry most of the sympathetic fibres to the hand and foot. With two exceptions all the nerve lesions were at or above the level of the knee or elbow. 3. Sympathectomy gives marked relief of pain in most cases of causalgia. Prompt treatment is essential to prevent the crippling deformities which follow prolonged voluntary immobilisation of the painful limb. The results of preganglionic are superior to those of postganglionic sympathectomy. 4. The possible pain pathways are discussed, and an explanation is offered for the successful results of sympathectomy in the treatment of causalgia.
