Fracture of the proximal phalanx of the little finger in children: a classification and a method to measure the deformity.
OBJECTIVE: To develop an improved method for measuring the deformity caused by fracture of the proximal end of the proximal phalanx of the little finger in children. DESIGN: A prospective case study. SETTING: Regional hospitals with an orthopedic service. PATIENTS: Forty-two children with a proximal phalangeal fracture of the little finger and 42 children without a phalangeal fracture, who acted as a control. The type of deformity resulting from the fracture was noted, and the angle of deformity was measured. Rotational deformities were measured clinically in all patients and angulation deformities were measured from radiographs. The deformities were graded and classified. MAIN OUTCOME MEASURES: Measurements of the fracture deformity before and after manipulation. RESULTS: There were 38 ulnar angulation deformities, 26 dorsal angulation deformities, 10 ulnar rotation deformities, 3 palmar angulation deformities, 2 radial angulation deformities and 1 radial rotation deformity. The deformities could be graded into 6 different types. CONCLUSION: The measurements of deformity made it possible to describe and classify isolated deformities and combinations of various deformities.

Forces generated in guide-wires when drilling human bone.
In orthopaedic surgery guide-wires are extensively used for the drilling of pilot holes in human bones to allow further drilling, reaming and screw-tapping to take place in the repair and reconstruction of fractures. The guide-wires are generally 1.5 to 2.5 mm in diameter and have a three-faceted point with or without a screw thread. This paper describes drilling tests carried out using both types of guide-wire and these are compared with results obtained from a two-faceted geometry developed during this research. Tests were performed on the heads of femurs which had been removed during hip arthroplasty. A variable speed drilling machine together with a very sensitive drilling dynamometer were used for measuring the torque and thrust during the experimental stage of the research. This equipment was developed as part of an overall research programme into the mechanics of drilling of human bone. The indications are, firstly, that little advantage is gained by using a threaded-point guide-wire. In fact using a thread on the guide-wire can be a disadvantage. Secondly, the thrust cutting force is dependent on the spindle speed and feed. An optimum set of speeds of between 800 and 1400 r/min is recommended for 2.5 mm diameter guide-wires.
