In fractures electrical currents generated by piezoelectric and junctional diode effects initiate and augment healing. Conductive fixators may interfere with these currents causing delayed/nonunion which can be avoided by non conductive fixators, facilitating osteosynthesis. Null hypothesis of no difference and two tailed alternate hypothesis of any could be better was used. Impugn change in Electrical properties for demarcating union rate.

Patients of Gustillo's grade I and II tibia fractures were randomised in conductive and non conductive fixator groups in a blinded manner. Electrical and clinico-radiological properties were compared every two weeks for 20 weeks, recoding magnitude and significant difference. Capacitance(p=0.03), Impedance(p=0.002), Inductance(p=0.01) and Reactance(p=0.02) are the electrical parameters which not only demarcated union rate but orchestrated diagnosis of fracture healing. In Non-conducting group, after removal of fixator at week 10, Local Tenderness was consistently absent, Rust Score was higher at week 18 and 20(p=0.01), absence of abnormal mobility was 58% higher and 100% at week 12(p < 0.05), Presence of weight bearing was higher from week 16(OR=15, p=0.03), presence of transmitted movement was 2.4 times higher at week 10(95% CI=0.17–34.93, p=0.52) and was 100% at week 14.

Fractures heal at a faster rate if fixed by insulated non-conducting external fixators. Electrical parameters can be used to demarcate and monitor fracture healing.

Periprosthetic fracture of the femur after hip arthroplasty is a difficult problem. Management depends on different clinical factors and these are fractures are managed at District General Hospitals.

Present series is of fifty such fractures presenting between 1999 and 2004 in two District General Hospitals in England. Number of female patients were more than males and majority of patients sustained these injuries after trivial fall.

Outcome of management are analysed according to modified ‘Tower and Beals’ criteria (1999).

Eleven patients lost to follow-up, twelve patients died (mortality was twenty-four percent) during follow-up. Twenty-one patients progressed to clinical and radiological union at an average of eight and eleven months respectively. Six patients are under follow-up.

Although several results are published in literature but the present result is comparable to the most literatures. If certain principles are followed comparable results can be obtained in District General Hospitals by Surgeons with a special interest in the management of these fractures.

We conducted a randomised controlled trial to compare external fixation of trochanteric fractures of the femur with the more costly option of the sliding hip screw. Patients in both groups were matched for age (mean 67 years, 50 to 100) and gender. We excluded all pathological fractures, patients presenting at more than one week, fractures with subtrochanteric extension or reverse obliquity, multiple fractures or any bone and joint disease interfering with rehabilitation. The interval between injury and operation, the duration of surgery, the amount of blood loss, the length of hospital stay and the cost of treatment were all significantly higher in the sliding hip screw group (p < 0.05). The time to union, range of movement, mean Harris hip scores and Western Ontario and McMaster University knee scores were comparable at six months. The number of patients showing shortening or malrotation was too small to show a significant difference between the groups. Pin-track infection occurred in 18 patients (60%) treated with external fixation, whereas there was a single case of wound infection (3.3%) in the sliding hip screw group.
