Case ReportsIntertrochanteric fractures of the hip treated with the hip compression screw: analysis of problems.
Seventy-five patients were treated for intertrochanteric hip fractures with the hip compression screw. There were 4 cases in which the lag screw was inserted twice into the femoral head. Three of these patients had a poor result due to superolateral migration and extrusion of the lag screw. ⋯ Satisfactory guide wire placement is essential for a one time, precise insertion of the lag screw into the femoral head. The use of a threaded tip guide wire minimizes the chance of it falling out when withdrawing the reamer or tap. If the position of a lag screw is unacceptable, it seems better to insert a flanged nail rather than a second screw in a second track.

The mechanisms of severe arterial injury in surgery of the hip joint.
Vascular accidents occurring in the course of hip surgery may reach potentially catastrophic dimensions by posing an immediate and sudden threat to life and limb. This is a report of 15 cases with severe arterial injury representing 0.2--0.3% of all reconstructive hip operations performed during an 8 year period. In 6 cases perforation of either the external iliac artery, the common femoral artery of main branches of the lateral and medial circumflex femoral artery were caused by the tip of a narrow-pointed Hohmann retractor used to expose the hip joint. ⋯ For hemorrhage resulting during replacement of firmly embedded hip prosthesis it might become necessary to ligate the internal iliac artery. Reconstruction of obliterated arteries should call for the cooperation of the vascular surgeon for eventual angioplasty. Angiologic examination of the lower extremities is mandatory whenever severe arterial trauma has occurred in the course of hip surgery and is best performed by measuring the ankle blood pressure with a Doppler ultrasound probe.
