The efficacy of modern drugs in the treatment of tuberculosis of the spine has been evaluated by a personal follow-up for three to ten years. Operation on the vertebral lesion was done only for those patients with or without neural complications who
1. In Northern Ireland a campaign to eradicate congenital dislocation of the hip by neonatal demonstration of abnormal laxity and early splintage has been reviewed. The number of live births in the area covered is approximately 30,000 per annum. 2. The results to date suggest that the problem has been greatly over-simplified. The number of established dislocations has not fallen appreciably. 3. Failures have occurred both in early diagnosis and in early treatment. 4. To help close the diagnostic net all children should be screened again during the first year. Infants born by breech presentation and infants with a family history of dislocation should have radiographs taken in the early months, even if clinical tests are negative. 5. With regard to neonatal treatment, early splintage has
1. The pathology and pathogenesis of dislocations and fracture-dislocations of the cervical spine has been reviewed. 2. A method of treatment using skeletal traction and manipulation under relaxant general anaesthesia is described. Results of treatment are given for all patients admitted to the Centre with flexion-rotation dislocations of the cervical spine complicated by neurological lesions, between November 1961 and December 1968. 3. After reviewing the literature and considering the results obtained in seventy-six cases, we advocate a policy of conservative management with gentle manipulation of the cervical spine in selected cases, reduction being maintained thereafter by skeletal traction. We reserve operation for the few cases that demonstrate late instability or for those rarer cases in which manipulation
1. Sixty-three fractures of the femur occurring in forty-eight patients with Paget's disease are presented. 2. In patients with Paget's disease the femur is the bone most often fractured, although the risk of fracture is probably not much greater than that of the normal population. 3. Many femoral fractures in Paget's disease are spontaneous and are preceded by pain. Extension of a stress fracture is the most likely cause. 4. All eleven femoral neck fractures in this series
1. A series of 705 fractures of the tibia is reviewed, 674 of which were treated conservatively. 2. The factors most conducive to delayed or non-union are initial displacement, comminution, associated soft-tissue wound and infection. The extent to which these are combined in any fracture determines its "personality" and its inherent propensity for union. 3. Eight fracture types are differentiated based on the above "personality rating." The incidence of delayed union or non-union varies from 9 per cent in the most favourable type to 39 per cent in the least favourable. Infection raises the incidence to 60 per cent. Comparative statistics which
Continuous strontium administration first induces typical "rickets" in young rats receiving adequate calcium phosphorus and vitamin D but later the widened cartilage spontaneously calcifies intermittently leaving transverse bands consisting largely of osteoid tissue in the metaphysis; in addition to intermittent calcification bone changes indicate that skeletal growth is not uniformly progressive. Subsequently areas of the epiphysial cartilage
Sinus-track cultures were compared prospectively with cultures from operative specimens in 55 patients with chronic bone infection. There was a total of 115 operative isolates; 102 of the sinus-track isolates were identical (88.7%), showing a specificity of 95.7% and a predictive value of 90.3%. A sinus-track specimen proved to be a reliable source for the isolation of all bacteria causing chronic bone infection except Staphylococcus epidermidis, provided that material from the depths of the sinus was aspirated by syringe from an active flowing sinus and inoculated immediately on culture media. Cotton-swab sinus specimens were unreliable for the isolation of mycobacteria, and could miss many pyogenic bacteria, or contain contaminants. Tuberculous bone infection should be suspected if there is no growth of any pyogenic bacteria or if there is growth of Staphyloccocus epidermidis alone on routine aerobic and anaerobic sinus cultures. Mycobacteria can often be identified from sinus-track culture from patients in whom operative culture, histopathology and clinical examination have
To assess the diagnostic value of C-reactive protein (CRP), leucocyte count (LC), and erythrocyte sedimentation rate (ESR) in late fracture-related infection (FRI). PubMed, Embase, and Cochrane databases were searched focusing on the diagnostic value of CRP, LC, and ESR in late FRI. Sensitivity and specificity combinations were extracted for each marker. Average estimates were obtained using bivariate mixed effects models.Aims

We present the short- and medium-term clinical results of thermal shrinkage in selected groups of patients with multidirectional or capsular stretch-type instability. We treated 56 patients (61 shoulders) by laser-assisted capsular shrinkage (LACS) and 34 patients (38 shoulders) by radiofrequency (RF) capsular shrinkage. The two groups were followed for mean periods of 40 months and 23 months, respectively. In the LACS group the mean Walch-Duplay score improved to 90 points 18 months after the operation, but then declined to a plateau of about 80 points; 59% of patients considered their shoulders to be ‘much better’ or ‘better’ but there was a failure rate of 36.1%. For the RF group the mean Walch-Duplay and Constant scores were 80 points at the various follow-up times; 76.3% of patients considered their shoulder to be ‘much better’ or ‘better’. RF

Cementless femoral stems must be correctly sized and well-seated to obtain satisfactory biological fixation. The change in sound that occurs during impaction of the femoral broach is said to indicate good fit, but this has not been widely studied. We set out to find whether the presence or absence of these sound changes could predict correct sizing. We recorded the sound generated during femoral broaching for 105 cementless total hip arthroplasties using the Corail stem. Four cases were excluded, leaving 101 recordings for analysis. There were 36 male patients and 65 female patients, with a mean age of 69.9 years (Aims

As part of a prospective study of 476 total knee replacements (TKR), we evaluated the use of manipulation under anaesthesia in 47 knees. Manipulation was considered when intensive physiotherapy
Axial radiographs were obtained under valgus and external rotation stress at 45° of knee flexion with and without contraction of the quadriceps muscle in order to assess the dynamics of patellar subluxation or dislocation. The radiography was performed on 82 knees in 61 patients with patellofemoral instability, and on 44 normal knees. The lateral patellofemoral angle and the congruence angle were measured and compared with the conventional Merchant views. Both parameters showed greater differences between symptomatic and normal knees on the stress radiographs obtained without quadriceps contraction. There was a major difference in the lateral patellofemoral angles between the groups, which clearly distinguished symptomatic knees from normal controls. Congruence angles on stress radiography had a significant correlation with the functional scores obtained after a period of conservative treatment and a positive correlation with the frequency of patellar subluxation. When the quadriceps contracted, two patterns of patellar shift were observed. While the patella reduced into the trochlear groove in all normal knees and about 70% of the symptomatic knees, contraction of the quadriceps caused further subluxation of the patella in the remaining symptomatic knees. All the knee joints which showed this displacement
We report the results of imaging with labelled white cells in 52 patients before the revision of 54 cemented joint prostheses at which the diagnosis of infection was made from biopsies. Twenty-five hips were imaged with 111In-oxine-labelled cells; 20 hips and 11 knees were imaged with 99mTc-hexamethylpropylene-amineoxime-labelled cells. Of these, 13 hips and five knees proved to be infected. The scans taken together had an accuracy of 82%, a sensitivity of 44% and a specificity of 100%. Indium scans gave 37% sensitivity, 99mTc labelling 50% sensitivity. Infected arthroplasties with positive scans had presented significantly earlier than those with negative scans, the time after the original insertion being 1.1 years for the true-positive scans and 6.1 years for the false-negative scans. The value of labelled white-cell scans in the detection of infection in
Displaced fractures of the forearm in children are often treated conservatively, but there is a relatively high incidence of redisplacement, malunion and consequent limitation of function. We have performed percutaneous Kirschner (K) wire fixation in 72 such children under the age of 14 years, of which 57 were reviewed for our study. Both the radius and ulna were fractured in 45 (79%), the radius only in eight and the ulna only in four. The mean initial angulation was 19° in the lateral plane and 9° in the anteroposterior plane for the radius and 15° and 9°, respectively, for the ulna. In 42 patients (74%) we performed closed reduction. In the remaining 15 (26%) closed reduction
