Intertrochanteric fractures of the femur: a randomized prospective trial comparing the Pugh nail with the dynamic hip screw

Over a 14-month period, 100 consecutive cases of intertrochanteric fracture were randomly allocated to be treated by either Pugh nail-plate or Dynamic Hip Screw (DHS) fixation. Although there were 11 cases of malreduction and/or suboptimal positioning of the fixation device in the femoral head, only two of these gave long-term problems. Despite the difference in configuration of the devices and a considerable disparity in price, patient satisfaction and the incidence of untoward radiological features at an average of 6 months after surgery were similar in the two groups. A trifin-ended device would thus appear to be a reliable alternative to the more commonly used hip screw systems for intertrochanteric fracture.

Seventy-four patients with trochanteric fractures of the femur were treated with Ender rods and thirty-eight patients with Compression Hip Screw.Comparison was made between the two devices to acertain either of which is better.Operative blood loss was less and operative time was shorter for the Ender method than for the Compression Hip Screw. But Ender method offered high level of problems, such as backout of the rods, external rotation, varus deformity of the femoral neck, and especially knee pains.Conclusively, Compression Hip Screw system is more preferable to use in the treatment of trochanteric fractures of the femur.

Prevention of rotation of the femoral head during internal fixation of subcapital fractures

A simple technique for preventing rotation of the femoral head during fixation of a subcapital fracture with an AO dynamic hip screw system is described.

30 fractures of the proximal end of the femur were stabilised with so-called "dynamic hip screws" (AO/ASIF). This method seems to be more suitable for some inter-trochanteric fractures which pose problems questioning our usual treatment with Ender's elastic round nails. The dynamic hip screw system is also more stable for femoral neck fractures of type Pauwels III than 4 cancellous bone screws. One phenomenon which can not yet be fully explained is the slipping out of the screw to an extent unobserved in other procedures.
