Axial Rotation Test for Trapeziometacarpal Joint Hypermobility in the Normal Population.

Background: The objective was to quantify joint laxity in healthy volunteers by measuring the passive axial rotation of the trapeziometacarpal joint using the axial rotation test.

Methods: Eighty volunteers (34 men and 46 women) were subjected to the axial rotation shear test and the degree of total rotational motion (TRM) was assessed. Volunteers were divided into Group I with a range of 18-50 years old and Group II for 51 years and older.

Stacked-blade, single-cut, ulnar-shortening osteotomy.

The authors reviewed a 10-year consecutive series of ulnar-shortening osteotomies using a freehand, single oblique cut with 2 or 3 stacked saw blades. Twenty-one patients (23 wrists) with chronic ulnar impaction syndrome (mean age, 45 years; range, 16 to 73 years) demonstrated an average preoperative ulnar variance of +2.1 mm (range, 0.

Comparison of Extension Orthosis Versus Percutaneous Pinning of the Distal Interphalangeal Joint for Closed Mallet Injuries.

We compared a static extension orthosis with percutaneous pinning of the distal interphalangeal joint (DIPJ) for treatment of closed mallet injuries. After receiving counsel about treatment options, 44 patients (25 women and 19 men; mean age, 57 years) freely chose orthosis and 18 patients (5 women and 13 men; mean age, 51 years) chose pinning. Both the extension orthosis and the pin remained in place for 6 weeks; the pin then was removed, and the care in both groups was transitioned to nighttime orthosis use for an additional 6 weeks.
