1. The three age types of acute haematogenous osteomyelitis are conditioned in their respective clinical features by the differing nature of their vascular bone pattern. 2. In the infant the condition causes severe and often permanent epiphysial damage and joint infection, a large involucrum but only transient damage to the shaft and metaphysis. 3. In the child the condition is responsible for extensive cortical damage with involucrum formation, but, except for some stimulation of growth, permanent damage to the growth cartilage and to joints is exceptional. Chronicity of the disease is rare if treatment has been effective. 4. In the adult acute osteomyelitis of the long bones is rare. It causes very frequent joint infection; the cortex is absorbed instead of sequestrating. The whole of the bone is invaded and frequently leaves chronic infection in the bone marrow. 5. The vascular characteristics of the bones in each age group and their relation to the onset of infection are described. 6. Some
Three elderly sibling dwarfs are reported from a large and otherwise normal family. Their condition is an unusual and irregular form of cartilaginous defect, combined with club-feet, and bearing some resemblance to the Morquio type. A brief consideration of the literature of the generahised developmental bony syndromes shows confusion of thought and nomenclature. A plea is therefore made for simplification and a rational and simple grouping of these conditions is attempted. It seems particularly desirable that many confusing names for particular syndromes should be scrapped (for example, dyschondroplasia, chondro-osteodystrophy), although quite evidently the terms achondroplasia and osteogenesis imperfecta must remain because of their long-standing and
1. Fat embolism occurs in a high percentage of all cases of injury and it is a relatively frequent complication of fractures of the long bones in civilian accidents as well as battle casualties. 2. The diagnosis can usually be established by the clinical features together with certain physical signs which must however be sought deliberately. 3. Important clinical features are the mental disturbance, alternation of coma with full consciousness, petechial haemorrhages in the conjunctiva and skin, and typical changes in the retina. 4. Evidence is still conflicting as to whether the fat arises by embolism from an injured bone, or by
Over 200 high-velocity missile injuries treated in a low-technology environment were audited under the aegis of the International Committee of the Red Cross Hospitals in Afghanistan and Northern Kenya. Femoral fractures were treated either by traction or external fixation using a uniaxial frame. The results showed that patients treated by external fixation remained in hospital longer than those treated on traction. The positional outcome was identical in both groups. In tibial fractures the external fixator was only of extra benefit in those of the lower third when compared with simple plaster slabs unless more complex procedures such as flaps or vascular repair were to be performed. In complex humeral fractures, external fixation resulted in long stays in hospital and a large number of interventions when compared with simple treatment in a sling. We conclude therefore that in an environment where facilities are limited and surgeons have only
We undertook a prospective, controlled trial which compared two rehabilitation programmes for 86 patients who sustained two-part fractures of the proximal humerus. Patients were randomised either to receive immediate physiotherapy within one week (group A) or delayed physiotherapy after three weeks of immobilisation in a collar and cuff sling (group B). At 16 weeks after the fracture, patients in group A had less pain (p <
0.01) and had greater shoulder function (p <
0.001) than those in group B. At 52 weeks, the differences between the groups had reduced. Although group A still had greater shoulder function and less pain, there was no statistical difference when compared with group B. By analysis of the area under the curve, an overall measure up to the 52-week period, group A experienced less pain as measured by the SF36
Heritable thrombophilic disorders have been proposed as one of the causes for Legg-Calvé-Perthes disease. A total of 62 patients diagnosed with this disease between 1988 and 1997 and 50 controls were screened for thrombophilia. The incidence and relationship of thrombophilia to the severity of the disease were evaluated. One patient and none of the controls had protein S deficiency. One of the control group and one of the patients had protein C deficiency with the latter child also having a combined deficiency with a mutant factor V gene. The number of children with a mutant factor V gene, protein C deficiency, who were homozygous for the C 677T polymorphism of methylenetetra-hydrofolate reductase or were heterozygous for mutant G20210A prothrombin did not differ statistically in the study and the control groups. No patient had antithrombin deficiency or positive lupus anticoagulant. We found no correlation between thrombophilia and the extent of the disease. The most common risk factors for arteriovenous thromboembolism showed no statistical significance in our patients compared with the control group or with the

Informed consent is a very important part of surgical treatment. In this paper, we report a number of legal judgements in spinal surgery where there was no criticism of the surgical procedure itself. The fault that was identified was a failure to inform the patient of alternatives to, and material risks of, surgery, or overemphasizing the benefits of surgery. In one case, there was a promise that a specific surgeon was to perform the operation, which did not ensue. All of the faults in these cases were faults purely of the consenting process. In many cases, the surgeon claimed to have explained certain risks to the patient but was unable to provide proof of doing so. We propose a checklist that, if followed, would ensure that the surgeon would take their patients through the relevant matters but also, crucially, would act as strong evidence in any future court proceedings that the appropriate discussions had taken place. Although this article focuses on spinal surgery, the principles and messages are applicable to the whole of orthopaedic surgery. Cite this article:
The aim of this study was to investigate the incidence, risk factors, and outcome of venous thromboembolism (VTE) following anterior cruciate ligament (ACL) reconstruction in a nationwide cohort. All ACL reconstructions, primary and revision, that were recorded in the Swedish Knee Ligament Register (SKLR) between 2006 and 2013 were linked with data from the Swedish National Board of Health and Welfare. The incidence of VTE was determined by entries between the day of surgery until 90 days postoperatively based on diagnosis codes and the prescription of anticoagulants. Risk factors, outcome, and the use of thromboprophylaxis were analyzed. Descriptive statistics with multivariate analysis were used to describe the findings.Aims
Patients and Methods
Single-stage revision is not widely pursued due to restrictive inclusion criteria. In this study, we evaluated the results of single-stage revision of chronically infected total hip arthroplasty (THA) using broad inclusion criteria and cementless implants. Between 2010 and 2016, 126 patients underwent routine single-stage revision with cementless reconstruction with powdered vancomycin or imipenem poured into the medullary cavity and re-implantation of cementless components. For patients with a culture-negative hip, fungal infections, and multidrug-resistant organisms, a direct intra-articular infusion of pathogen-sensitive antibiotics was performed postoperatively. Recurrence of infection and clinical outcomes were evaluated. Three patients died and 12 patients (none with known recurrent infection) were lost to follow-up. There were 111 remaining patients (60 male, 51 female) with a mean age of 58.7 (Aims

We compared retrospectively consecutive series of patients with cervical dislocation treated at two Australian centres. In Perth, 82 patients were treated by closed reduction and postural nursing. In Adelaide, 85 patients had closed reduction and early surgical stabilisation by interbody fusion. There were 46 bilateral dislocations, 101 unilateral dislocations, and 20 anterior subluxations. On admission 30 patients had complete tetraplegia, 17 incomplete tetraplegia, and 120 had minimal or no neurological loss. Our results indicated that closed manipulation under
The aim of this study was to evaluate the functional outcome in patients undergoing implant removal (IR) after fracture fixation below the level of the knee. All adult patients (18 to 75 years) undergoing IR after fracture fixation below the level of the knee between November 2014 and September 2016 were included as part of the WIFI (Wound Infections Following Implant Removal Below the Knee) trial, performed in 17 teaching hospitals and two university hospitals in The Netherlands. In this multicentre prospective cohort, the primary outcome was the difference in functional status before and after IR, measured by the Lower Extremity Functional Scale (LEFS), with a minimal clinically important difference of nine points.Aims
Patients and Methods
Forty-eight patients with achondroplasia and 24 with hypochondroplasia have been reviewed in order to clarify the differences between the two disorders and establish the height, body proportions and other clinical and radiological variations within each group. Some of the "classical" findings in achondroplasia are not always present, and hypochondroplasia at its most severe is indistinguishable from achondroplasia at its least severe. The frequency of spinal stenosis and neurological complications was established in an unselected group of 27 achondroplastic and 12 hypochondroplastic patients aged 10 years and over. Only three of the former were free of symptoms but only three developed serious complications (11 per cent). Measurement of radiographs of the lumbar canal did not in
The late results of early treatment of congenital dislocation of the hip in the von Rosen splint have been recorded in a follow-up study of 111 children with an average age of ten years (range eight to sixteen). The clinical diagnosis had been made within two days of birth and in most cases confirmed by radiological examination. Splintage was in all cases begun within the first few days and maintained for an average period of ten weeks. Two cases of failure of the initial treatment were encountered but had good final results. The follow-up study included a radiological examination in which were recorded the

1. A case of essential osteolysis is presented, occurring in a young man of eighteen with no known family history and developing progressively from early childhood. The condition was radiologically evident in the elbows, hands and feet, and was accompanied by atrophy of the cancellous bone of the epiphyses of the shoulders and knees. It was also associated with certain abnormalities of the skull and vertebrae. The patient died from a nephropathy of late onset. 2. Examination of the left foot revealed on the radiologically "lysed" bony extremities a very slow process of erosion affecting essentially the epiphysial and metaphysial cortical bone, of a non-inflammatory nature and accompanied by disappearance of the hyaline cartilage. The extremities not radiologically "lysed" showed signs of erosion that were histologically similar but not macroscopically evident; they were accompanied by regressive changes in the hyaline cartilage. 3. There were no signs of renal osteodystrophy or of Sudeck's dystrophy. 4. Post-mortem tests revealed an increase in the seromucoids and failed to reveal the presence of proline in the serum or of proline and hydroxyproline in the urine. 5. The authors discuss the place of this condition among osteolyses in
1. The strength of the pelvic arch depends on the integrity of the anterior interpubic ligament, whose strength has been demonstrated by dissections. Once that ligament is divided the sacro-iliac ligaments offer little resistance to opening out of the pelvis. 2. The structure of the pelvis and hips is compared to an arcade formed by a central and two lateral arches. The weight of the trunk is transmitted to the lower limbs through this arcade. 3. Fractures of the pelvis are classified according to the mechanism of production. The case for anatomical reposition and internal fixation is stated, and case histories are given to illustrate the disabilities due to persistent deformity. 4. Reduction can be achieved as late as two or three weeks after injury. However, if early operation for visceral injury is necessary, there is a strong case for combining this with open reduction and fixation. In some cases the patient's
