ANTERIOR FUSION OF THE SPINE FOR INFECTIVE LESIONS IN ADULTS
Authors: Kemp H. B. S. , Jackson J. W. , Jeremiah J. D. , Cook Josephine 
Published: February 2018

1. The results of treatment of 117 tuberculous and fourteen other types of infection of the spine in adults by anterior fusion and chemotherapy have been reviewed. 2. It is suggested that anterior fusion is justified because: a) it permits isolation of the organism, and hence the determination of drug sensitivities and appropriate chemotherapy; b) removal of the diseased tissue and the stabilisation of the affected segment by iliac bone grafts can be effected, leading to rapid healing by bony fusion with little further collapse; c) rehabilitation of the patient is hastened; and d) the incidence of reactivation is probably diminished.
CONGENITAL CLUB FOOT
Authors: Waisbrod Hanan 
Published: February 2018

1. An anatomical study of congenital club foot in various stages of foetal development is presented, and the literature is reviewed. 2. The most striking finding was deformity of the talus and in particular a change in its angle of declination. 3. That deformity was present in feet whose deformity could not be corrected by gentle manipulation; it was absent in feet whose deformity could be so corrected. 4. Abnormality of the tendon and insertion of the tibialis posterior muscle was found in most cases. 5. Speculations are advanced concerning the nature and cause of the talar deformity.
STATIC AND DYNAMIC PROBLEMS IN SPASTIC CEREBRAL PALSY
Authors: Reimers Jørgen 
Published: February 2018

1. Analysis of the static and dynamic conditions in spastic cerebral palsy leads to the conclusion that contractures of the hip, knee and ankle should be released from above downwards, and that the full benefit is obtained only when all contractures have been corrected. 2. Only when these joints are mobilised by removal of the significant contractures is the spastic patient able, despite other handicaps, to sit, stand and walk with the least hindrance and the least cosmetic fault. 3. In our Danish experience, inadequate or poor results from the orthopaedic surgery of cerebral palsy are mainly due to the fact that patients with contractures are operated on too little and too late, or not in the correct sequence.
PLANTAR PRESSURES IN HEALTHY CHILDREN AND IN CHILDREN WITH MYELOMENINGOCELE
Authors: Hay Malcolm C. , Walker Geoffrey 
Published: February 2018

1. It has been shown in fifty normal feet that the perpendicular static plantar pressures rise by about 35 per cent between the ages of five years and maturity. 2. It is very likely that similar increases in plantar pressures occur between two and five years of age. 3. The plantar pressures in seventy-eight feet of children with spina bifida were with a few exceptions substantially higher than those of normal children of the same age. It is likely that this is so, at least in part, because the feet of children with spina bifida are smaller than normal. 4. This increase in perpendicular static pressure during growth must be relevant in the production of trophic foot ulceration. 5. The existence and importance of "flail deformity" as a factor producing areas of increased pressure and ulceration in anaesthetic feet is postulated.
ENTRAPMENT NEUROPATHY OF THE SURAL NERVE
Authors: Pringle Robert M. , Protheroe Keith , Mukherjee Sadhan K. 
Published: February 2018

1. Four cases of sural nerve entrapment lesions in the ankle and foot are reported. 2. All the patients gained complete relief of symptoms following neurolysis. 3. The presence of a ganglion in relation to the sural nerve in the ankle and foot is a helpful sign in the diagnosis of this condition.
DISPLACED SUPRACONDYLAR FRACTURES OF THE ELBOW IN CHILDREN
Authors: Fowles J. V. , Kassab M. T. 
Published: February 2018

Displaced extension supracondylar fractures of the elbow 1. One hundred and ten children were treated by reduction and stabilisation by two pins inserted laterally at an angle of 30 degrees to one another. 2. The complications before and after treatment included fifteen nerve lesions in thirteen patients. The ulnar nerve was involved on one occasion only. Solitary radial nerve injuries occurred with postero-medial displacement of the distal fragment, while median nerve and brachial artery injuries were associated with postero-lateral displacement. All the lesions recovered spontaneously. 3. There were no ischaemic complications after treatment, despite the ligation of one ruptured brachial artery. 4. The average stay in hospital was four days, compared with twenty days for thirty-two other patients treated in traction because of gross oedema. 5. Of eighty patients seen six months to five years after the fracture, seventy (or 87·5 per cent) had excellent or good results, seven patients with marked varus deformities had fair results, and two patients had poor results with very stiff elbows. Displaced flexion fractures 1. The clinical features, complications and treatment of seventeen cases are described. 2. There were no complications involving the median or radial nerves or the brachial artery, but three patients had a lesion of the ulnar nerve. 3. Nine children had closed reduction and fixation by two lateral percutaneous pins. 4. Reduction was difficult and the results poor compared with extension fractures. Closed reduction failed in one-third of the children, and the functional and cosmetic results were unsatisfactory in over half the patients reviewed.
TRAUMATIC DISLOCATION OF THE RADIUS AT THE ELBOW
Authors: Wiley J. J. , Pegington John , Horwich J. P. 
Published: February 2018

1. Isolated dislocation of the radius at the elbow occurs most commonly as a pronation injury, associated with slight elbow flexion and a varus strain. Disruption of the radio-ulnar articulation occurs primarily because of tearing of the annular ligament, which is the most important reinforcing structure of this joint. The tensing of the interosseous membrane through neutral into supination, and consequently the approximation of the radius to ulna, supports the recognised supination manoeuvre to reduce such an injury. 2. It is suggested that this injury may be more common than previously appreciated. It may be not diagnosed, it may be over-diagnosed as total dislocation of the elbow, or it may be belatedly diagnosed as a congenital dislocation of the radial head.
THE EXPERIMENTAL INDUCTION OF LOCALISED SKELETAL TUBERCULOUS LESIONS AND THEIR ACCESSIBILITY TO STREPTOMYCIN
Authors: Tuli S. M. , Brighton Carl T. , Morton Harry E. , Clark Larry W. 
Published: February 2018

1. Chronic tuberculous osseous lesions were induced consistently in eight- to ten-week-old unvaccinated guinea-pigs by the insertion of Gelfoam impregnated with mycobacterium tuberculosis into the metaphysial region through a drill hole in the distal part of the femur. Typical tuberculous lesions developed by three weeks and many of them were followed for twelve weeks or more. 2. This experimental model establishes a reliable method of producing a localised lesion at a predetermined site without early death of the animal. The model is sufficiently similar to the human lesion, and may offer a reliable system for further investigations. 3. It was observed that streptomycin penetrates readily into tuberculous osseous lesions. The concentration of streptomycin found in the tuberculous lesion after a single intramuscular injection was much higher than the concentration considered sufficient to have an inhibitory effect on the human type of mycobacterium tuberculosis.
FRACTURE MANAGEMENT IN PATIENTS WITH HAEMOPHLLIA
Authors: Feil Edward , Bentley George , Rizza Charles R. 
Published: February 2018

1. The management of fractures in five patients with haemophilia is described: two patients had antibodies to antihaemophilic globulin. 2. The principles of management of injured haemophilia patients are described, as are the special problems in patients with antibodies to AHG. 3. Stability of the fragments must be achieved to prevent the hazards of displacement of the fracture, recurrent bleeding and pseudotumour formation which may threaten viability of the limb. 4. Stabilisation of potentially unstable fractures can be achieved at the onset by internal fixation. Plaster casts should be reserved for stable fractures or fractures occurring in young children.
STRESS FRACTURE OF THE FUSED LUMBO-DORSAL SPINE IN ANKYLOSING SPONDYLITIS
Authors: Yau Arthur C. M. C. , Chan R. N. W. 
Published: February 2018

1. The aetiology of a destructive lesion through a former interspace in a spine fused by ankylosing spondylitis is reviewed. 2. From the findings in three patients treated by anterior spinal fusion, evidence was obtained to show that a stress fracture, originating posteriorly between two fused spinous processes, leads to a pseudarthrosis between two vertebral bodies that may simulate a tuberculous lesion. 3. If spinal fusion is indicated, the anterior approach is recommended, both for direct observation of the lesion and to achieve sound union.
INCIDENCE OF INTERDIGITAL CLAVUS
Authors: Gillett H. G. Du P. 
Published: February 2018

1. An investigation of interdigital clavus or corn does not support the opinion that it is found most often in the web of the fourth interspace. 2. Most occur in that interval, but less than a third involve the web. 3. The commonest site is the area of impingement of the distal interphalangeal joint of the fifth toe on the proximal interphalangeal joint of the fourth.
SYSTEMIC RELEASE OF COBALT AND CHROMIUM AFTER UNCEMENTED TOTAL HIP REPLACEMENT
Authors: Kreibich D. N. , Moran C. G. , Delves H. T. , Owen T. D. , Pinder I. M. 
Published: February 2018

We measured the levels of cobalt and chromium in the serum in three groups of patients after uncemented porous-coated arthroplasty. Group 1 consisted of 14 consecutive patients undergoing revision for aseptic loosening. Group 2 comprised 14 matched patients in whom the arthroplasty was stable and group 3 was 14 similarly matched patients with arthritis awaiting hip replacement. Specimens were analysed using atomic absorption spectrophotometry. Aseptic loosening of a component resulted in a significant elevation of serum cobalt (p < 0.05), but not of serum chromium. The relative risk of a component being loose, if the patient had a serum cobalt greater than 9.0 nmol/l, was 2.8.
MIGRATION AND WEAR OF A HYDROXYAPATITE-COATED HIP PROSTHESIS
Authors: Önsten I. , Carlsson å. S. , Sanzén L. , Besjakov J. 
Published: February 2018

A consecutive series of 30 total hip replacements using a hydroxyapatite (HA)-coated, modular implant (Omnifit) was followed clinically and by roentgen stereophotogrammetric analysis for two years and compared with two control groups, one of 27 cemented Charnley sockets and one of 40 cemented Charnley stems. Omnifit sockets with a central gap between the dome of the socket and the acetabular bone in the postoperative radiographs, migrated less than sockets without such gaps (p = 0.01). After adjustment for patient-related factors (age, gender and weight), no significant difference was found between the two prostheses with respect to micromotion and wear. We conclude that the early fixation of the HA-coated Omnifit prosthesis compares with that of the cemented Charnley prosthesis.
FUNCTIONAL OUTCOME MEASURES AFTER DISPLACED INTRA-ARTICULAR CALCANEAL FRACTURES
Authors: Hildebrand K. A. , Buckley R. E. , Mohtadi N. G. H. , Faris P. 
Published: February 2018

We have devised a new scoring system using visual analogue scales (VAS) to determine the functional outcome in 15 patients with 20 displaced intra-articular calcaneal fractures, confirmed by CT. The average follow-up was 19 months. A VAS was completed separately by the patient, the surgeon and an independent assessor. It showed satisfactory agreement between observers and strong correlations with a General Health Survey (SF36), a pain scale (McGill Pain Questionnaire) and a disease-specific, historical scale for calcaneal fractures (the Rowe score).
PERCUTANEOUS SCREW REMOVAL IN SLIPPED UPPER FEMORAL EPIPHYSIS
Authors: Gruber M. A. , Starkweather K. D. , Healy W. A. , Haralabatos S. 
Published: February 2018

Several authors have reported complications from screw removal after treatment of slipped upper femoral epiphysis by single screw fixation, and have attributed these to poor screw design. We have developed a simple and reliable method of screw removal which uses a cannulated 8.0 mm end-threaded cancellous screw (Smith & Nephew Richards Medical, Memphis, Tennessee) and a specially designed cannulated trephine. The method has been successful, with minimal complications, and a limited surgical exposure.
THE CEMENTLESS PM HIP ARTHROPLASTY
Authors: Dickob M. , Martini T. 
Published: February 2018

We implanted 300 uncoated cementless PM prostheses into 271 patients and followed 251 (92.6%) of them for four to seven years. By then 37 had already been revised for aseptic and three for septic loosening. The survival rate with implant failure as the endpoint was 88.8% for the cup and 85.3% for the stem after six years. There was a higher risk of implant loosening in congenital dysplasia, unilateral hip arthroplasty and obesity. The results of 225 unrevised hip replacements were assessed by questionnaire. Only 27.4% of the patients were completely free from pain and 17.9% had pain on walking any distance or at all times. The walking distance was for less than 30 minutes in 40%. Because of the poor results in comparison with other prostheses we do not recommend further use of the uncoated PM prosthesis.
A FLOATING PROSTHESIS FOR RADIAL-HEAD FRACTURES
Authors: Judet T. , de Loubresse C. Garreau , Piriou P. , Charnley G. 
Published: February 2018

We report our experience over seven years with a floating radial-head prosthesis for acute fractures of the radial head and the complications which may result from such injury. The prosthesis has an integrated articulation which allows change of position during movement of the elbow. We present the results in 12 patients with a minimum follow-up of two years. Five prostheses had been implanted shortly after injury with an average follow-up of 49 months and seven for the treatment of sequelae with an average follow-up of 43 months. All prostheses have performed well with an improved functional score (modified from Broberg and Morrey 1986). We have not experienced any of the complications previously reported with silicone radial-head replacement. Our initial results suggest that the prosthesis may be suitable for the early or delayed treatment of Mason type-III fractures and more complex injuries involving the radial head.
MRI OF EARLY OSTEONECROSIS OF THE FEMORAL HEAD AFTER TRANSCERVICAL FRACTURE

Published: February 2018

We have carried out a prospective study of 17 patients (14 women, 3 men) of mean age 48 years (21 to 76) with transcervical fractures of the femur using MRI to detect early evidence of avascular necrosis of the head. Two fractures were Garden stage I, 12 stage II, and three stage III. We performed internal fixation under radiological control at a mean of five days (2 to 15) after injury using a titanium cannulated cancellous screw or a titanium compression hip screw. MRI was performed at one, six and 12 months and then yearly after operation. T1- and T2-weighted images were obtained by a spin-echo technique. The duration of follow-up of patients who did not subsequently require replacement of the head of the femur was from 2 to 5 years (mean 3.2). One month after operation eight of the 17 hips showed a band of low signal intensity on T1-weighted images and high signal intensity on T2-weighted images indicating lesions in the femoral head away from the fracture line. These were of three types: type I was a small infarct at the superolateral region of the femoral head and was seen in three hips; type II was a shallow lesion from the superolateral region to the fovea of the femoral head (three hips); and type III was a large lesion occupying most of the femoral head (two hips). No further changes were seen in the MRI after six months from operation. Collapse of the femoral head did not occur in the three hips with type-I lesions, but two of the three type-II hips and both type-III hips subsequently collapsed. At the final follow-up the three hips with a type-I lesion and one with a type-II were still asymptomatic but radiography showed sclerosis in the femoral head corresponding to the MRI lesions. The nine hips which showed no changes on MRI at one month had no abnormal findings on physical examination, radiography or MRI at final follow-up.
STIFFNESS MEASUREMENTS TO ASSESS HEALING DURING LEG LENGTHENING
Authors: Dwyer J. S. M. , Owen P. J. , Evans G. A. , Kuiper J. H. , Richardson J. B. 
Published: February 2018

We describe a technique for measuring the Stiffness of regenerate bone after leg lengthening. This allows early identification of slow healing by reference to normal patterns. We determined the time of removal of the fixator from clinical and radiological information independent of the stiffness result. In a series of 30 leg lengthenings there were no refractures when the tibial stiffness had reached 15 Nm/° or the femoral stiffness 20 Nm/°. Three refractures occurred at lower stiffness values. The technique is simple to perform, will allow a reduction in plain radiography and is recommended for routine postoperative management.
DYNAMIC RADIO-ULNAR CONVERGENCE AFTER THE DARRACH PROCEDURE
Authors: McKee M. D. , Richards R. R. 
Published: February 2018

We reviewed 23 patients who had had 25 Darrach procedures for traumatic or post-traumatic disorders of the wrist at a mean follow-up of 75.5 months (36 to 121). The mean age at the time of operation was 61.1 years (34 to 82). All patients were reviewed in person. Assessment included a history, a questionnaire on patient satisfaction and a detailed physical examination. Standardised radiographs of both wrists were taken with the patient’s hands in a resting position and during maximal grip. Convergence of the distal ulnar stump towards the distal radius during maximal grip (dynamic radio-ulnar convergence) was seen in 14 wrists including five with actual contact (dynamic radio-ulnar impingement), but this produced symptoms in only two cases. The presence of dynamic radio-ulnar convergence did not correlate with grip strength, pinch strength, range of movement or wrist score, but was associated with increased length of excision of the distal ulna. Nineteen of the 23 patients were satisfied with the procedure. Dynamic radio-ulnar convergence is common after the Darrach procedure, but is rarely symptomatic; resection of the distal ulna remains a reliable procedure in the older patient with pain and loss of movement. Excision of the lower end of the ulna should be restricted to the least required to restore full rotation.
POSTOPERATIVE DEEP-VEIN THROMBOSIS IN ASIAN PATIENTS IS NOT A RARITY
Authors: Dhillon K. S. , Askander A. , Doraisamy S. 
Published: February 2018

Postoperative deep-vein thrombosis (DVT) is believed to be rare in Asians. We studied 88 consecutive patients in Malaysia who had operations for fracture of the proximal femur or for total hip or knee replacement. No patient had prophylaxis against DVT; bilateral ascending venography was performed between six and ten days after operation. A total of 55 patients (62.5%) showed venographic evidence of DVT. The prevalence was greatest after total knee replacement (76.5%), less after total hip replacement (64.3%) and smallest in the fracture group (50%). One patient developed symptomatic pulmonary embolism. In contrast to other reports from Asia, we found an incidence of postoperative DVT which is similar to that reported in Western populations. This suggests that the present practice of withholding routine prophylaxis against thromboembolism in Asian patients undergoing high-risk orthopaedic procedures should be reconsidered.
NON-OPERATIVE MANAGEMENT OF ANTERIOR CRUCIATE LIGAMENT INJURIES IN THE GENERAL POPULATION
Authors: Casteleyn P.-P. , Handelberg F. 
Published: February 2018

The operative treatment of lesions of the anterior cruciate ligament (ACL) in athletes has been widely advocated and performed. We have investigated the outcome of non-operative management in a lower-demand, general population. We reviewed a consecutive group of 228 patients, which excluded professional and high-level athletes, for two to 12 years after an ACL lesion had been diagnosed by arthroscopy. There was a low incidence of secondary ACL and meniscal surgery, 5.4% and 3.5% respectively, and all these procedures were performed during the first three years after the ACL injury. We studied a subgroup of 109 patients with follow-up of at least five years (mean 8.5 years) and evaluated them using the IKDC score. The general outcome was reasonably satisfactory, with 23% in grade A, 50% in grade B, 21% in grade C and only 6.4% in grade D. We found no statistically significant prognostic effect within this group as regards age, activity levels, or the incidence of associated lesions.
SYME’S AMPUTATION REVISITED
Authors: Gaine W. J. , McCreath S. W. 
Published: February 2018

We assessed 46 Syme’s amputees attending our prosthetic clinics in terms of the clinical and radiological condition of their stumps, their level of function and problems with the prosthesis. Twenty-five were compared with a matching group of 25 transtibial amputees in regard to activity, function and prosthetic behaviour. Function was similar in the two groups, but Syme’s amputees had a higher incidence of prosthetic failure. Overall, Syme’s amputees were pleased with their prostheses and their function. Childhood amputations were associated with fewer long-term problems in terms of function and stump problems Syme’s amputation is indicated for congenital foot deformities, fibular hemimelia and severe injury to the foot as long as the heel pad remains viable.
SHORT-TERM RECOVERY FROM HIP AND KNEE ARTHROPLASTY
Authors: Aarons H. , Hall G. , Hughes S. , Salmon P. 
Published: February 2018

There are many studies of long-term recovery from major joint arthroplasty, but little is known about the first days and weeks after operation. We measured function, emotional state and life evaluation before arthroplasty and at seven and 50 days after in a consecutive series of 40 hip and 23 knee replacements. Pain was relieved significantly at seven days after hip arthroplasty and even more at 50 days. In knee patients, pain relief was modest and was not apparent until 50 days. Functional ability was much improved by 50 days in hip patients, but hardly changed in knee patients. Positive mood and life satisfaction did not improve in either group. Our findings will help with more accurate information for patients before operation and also in judging the rate of recovery.
THE SURGICAL TREATMENT AND OUTCOME OF PATHOLOGICAL FRACTURES IN LOCALISED OSTEOSARCOMA
Authors: Abudu A. , Sferopoulos N. K. , Tillman R. M. , Carter S. R. , Grimer R. J. 
Published: February 2018

We reviewed the surgical treatment and oncological results of 40 patients with pathological fractures from localised osteosarcoma of the long bones to determine the outcome of limb salvage in their management. All had had adjuvant chemotherapy. There were 26 males and 14 females with a median age at diagnosis of 18 years (2 to 46) and a median follow-up of 55 months (8 to 175). We performed limb salvage in 27 patients and amputation in 13. The margins of resection were radical in five patients, wide in 26, marginal in six, wide but contaminated in two and intralesional in one. Local recurrence developed in 19% of those treated by limb salvage and in none of those who had an amputation. The cumulative five-year survival of all the patients was 57% and in those treated by limb salvage or amputation it was 64% and 47%, respectively (p > 0.05). Limb-sparing surgery with adequate margins of excision can be achieved in many patients with pathological fractures from primary osteosarcoma without compromising survival, but the risk of local recurrence is significant.
