Abstract:

Objective To provide anatomical data for local blocking treatment and the needle knife therapy through investigating features and anatomical variance of the soft tissue in the styloid process of radius. Methods Anatomical observation was performed at 30 adult wrist joints of cadaver samples. The diameter of upper and lower openings and length of the first extensor compartment, the distance from the first extensor compartment to radial artery and the distance from the first extensor compartment to superficial branch of radial nerve were measured. The septa of the extensor compartments and APL tendons were observed. Results In 19 specimens (63.3%), there was two tendons (APL and EPB) in one compartment. In 11 specimens (36.7%), there was APL and EPB in two separate compartments. In 21 specimens (70%) , APL had more than one tendon. The length, inside and outside diameters of lower opening and inside and outside diameters of upper opening of the first extensor compartment were (35.35±3.04) mm, (9.36±0.38) mm, (11.08±0.36) mm,(13.15±0.87) mm and (13.67±0.82) mm. The distance from the first extensor compartment to radial artery and the distance were (1.60±0.17)~(4.58±0.45) mm, (1.42±0.18 )~(4.59±0.45) mm from the first extensor compartment to superficial branch of radial nerve. Conclusion The first extensor compartment is a safe and effective area for treatment.
