Early versus delayed treatment of extension type-3 supracondylar fractures of the humerus in children.

We examined differences in the rate of open reduction, operating time, length of hospital stay and outcome between two groups of children with displaced supracondylar fractures of the humerus who underwent surgery either within 12 hours of the injury or later. There were 77 children with type-3 supracondylar fractures. Of these, in 43 the fracture was reduced and pinned within 12 hours and in 34 more than 12 hours after injury. Both groups were similar in regard to gender, age and length of follow-up. Bivariate and logistical regression analysis showed no statistical difference between the groups. The number of peri-operative complications was low and did not affect the outcome regardless of the timing of treatment. Our study confirmed that the treatment of uncomplicated displaced supracondylar fractures of the humerus can be early or delayed. In these circumstances operations at night can be avoided.

Osteotomy for congenital elevation of the scapula (Sprengel's deformity).

We report 12 consecutive cases of vertical scapular osteotomy to correct Sprengel's deformity, performed during a 16-year period, with a mean follow-up of 10.4 years. The mean increase in abduction of the shoulder was 53 degrees . The cosmetic appearance improved by a mean of 1.5 levels on the Cavendish scale. Neither function nor cosmesis deteriorated with time. We recommend the procedure for correction of moderate deformities with a functional deficit.

The changing epidemiology of acute and subacute haematogenous osteomyelitis in children.

We have reviewed the incidence of bacteriologically or radiologically confirmed acute haematogenous osteomyelitis in children under 13 years of age resident in the area of the Greater Glasgow Health Board between 1990 and 1997. In this period there was a fall of 44% in the incidence of both acute and subacute osteomyelitis, mainly involving the acute form (p = 0.005). This mirrors the decline of just over 50% previously reported in the same population between 1970 and 1990. Using multiple regression analysis a decline in incidence of 0.185 cases per 100,000 population per year was calculated for the 28-year period (p < 0.001). Staphylococcus was the most commonly isolated pathogen (70%). Only 20% of patients required surgery and there was a low rate of complications (10%). In general, patients with a subacute presentation followed a benign course and there were no complications or long-term sequelae in this group. Haematogenous osteomyelitis in children in this area is becoming a rare disease with an annual incidence of 2.9 new cases per 100,000 population per year.

Leg lengthening for short stature in Turner's syndrome.

We describe ten patients with Turner's syndrome (karyotype 45, XO) who had leg lengthening for short stature. A high incidence of postoperative complications was encountered and many patients required intramedullary fixation as a salvage procedure. We discuss the reasons for this and highlight the differences between our findings and those of a similar series recently reported. In view of the considerable difficulties encountered, we do not recommend leg lengthening in Turner's syndrome.

The orthopaedic implications of peripheral limb ischaemia in infants and children.

Peripheral limb ischaemia is rare in children. We have treated only 12 infants and children with this condition in the past 15 years at the Royal Hospital for Sick Children in Glasgow. There were nine neonates and three older children. Most were suffering from life-threatening illnesses or severe infection. Two were born with ischaemic arms with no apparent cause. We have analysed the factors leading to ischaemia, the outcome of the initial treatment and the later orthopaedic problems. Two required amputation of both legs, one of an arm, two of feet and one of toes. Two had skin grafts. All surgery was performed after demarcation was well established and delayed closure was used after amputation. Five children developed limb-length discrepancy or an angular deformity. To date two have required additional corrective surgery.

Children's proximal phalangeal neck fractures with 180 degrees rotational deformity.

Five patients under 4 years of age with 180 degrees rotational deformity of a proximal phalangeal neck fracture are described. All cases resulted from a direct shear force to the bone coupled with a sharp withdrawal reaction of the hand. All of the children were successfully treated with open reduction and internal fixation but only after fruitless attempts at closed manipulation and an initial lack of recognition of the severity of the fracture. Each child achieved a full functional recovery of the finger with clinical and radiological union at 4 weeks.

Symptomatic cortical irregularities of the distal femur simulating malignancy.

We reviewed the records and radiographs of seven children who presented with knee pain, local tenderness over the medial femoral condyle, and radiological irregularity of the distal medial metaphysis of the femur suggestive of malignancy. In the five patients who had biopsies, histological changes were consistent with musculotendinous avulsion, and the dissection of ten cadavers confirmed the site to be the insertion of part of the adductor magnus. The recognition of this lesion and knowledge of its benign nature may avoid unnecessary anxiety and needless biopsy.

Leg lengthening.

The combined experience of the Royal Hospital for Sick Children, Glasgow and the Robert Jones and Agnes Hunt Orthopaedic Hospital, Oswestry in lengthening 52 lower limb segments with the Orthofix device is reviewed. Forty-eight segments were lengthened by callotasis, 24 in patients with achondroplasia. Attempted lengthening with chondrodiatasis was performed in 4 patients with leg length discrepancy. With callotasis, planned lengthening was achieved in 43/48 (90%) of segments. There was a small number of significant complications. Angulation or buckling of the new bone was the commonest major complication, and was seen in 10% of segments. Pin tract infection was the predominant minor complication. Premature union was noted commonly in the femurs of achondroplastics, but could usually be overcome with manipulation under anaesthesia. We confirm that callotasis achieves its objectives with fewer complications and operations than the commonly used Wagner method which it should supersede. By contrast, we had major complications in all cases with chondrodiatasis and have abandoned this method.

Osteomyelitis of the calcaneum.

We reviewed 52 cases of osteomyelitis of the calcaneum. The clinical symptoms and signs were well defined, but different and less dramatic than those of long-bone osteomyelitis. Blood cultures were positive in 41% of cases and tissue cultures in 91%. Routine haematological tests were of little value, and radiological changes were often delayed, and were absent in 12%. With early diagnosis, treatment with antibiotics alone was usually effective, but complications and chronic disease were more likely if there was delay. Early diagnosis is the key to successful treatment. We describe a new physical sign and consider that diagnosis is almost always possible by clinical methods.

Physeal widening in children with myelomeningocele.

We report five examples of physeal widening in four children with myelomeningocele. In all cases there was rapid clinical resolution with the use of the patients' normal orthoses and minor limitation of activity, and there was no evidence of early epiphyseal closure or growth disturbance. We suggest that recognition of the pathological process before fracture occurred may explain the rapid return to normal.

Fractures of the femur in childhood.

Child abuse, usually diagnosed by its soft-tissue signs, is not often considered as a cause of fractures of the femur in young children. In this retrospective review of 150 such fractures we show that child abuse was suspected or proven in 22 per cent of the fractures in the under-5 year age group, and in 39 per cent of the under-1 year group.

Pin placement in slipped capital femoral epiphysis.

Standard radiographs taken at right angles to each other during the pinning of a slipped capital femoral epiphysis may not demonstrate pins protruding into the joint. In this study roentgenograms of 110 patients (148 hips) with slipped capital femoral epiphyses were analysed by a three-dimensional mathematical model of the femoral head and pin position. A computer was used to determine the spatial distance between the tip of the pin and the subchondral bone of the femoral head. Pin protrusion was found in 41 hips. In 22, protrusion was sufficient to have transgressed the joint space. Pin protrusion did not, however, appear to increase the risk of chondrolysis.
