Displaced fractures should be treated operatively in young active individuals because residual step-off may give a higher risk trapezio-metacarpal or scapho-trapezium-trapezoid osteoarthritis. 25 Percutaneous Kirschner's wire fixation, oblique external traction, and open reduction and internal fixation have all been reported in the literature ...

Scapho-trapezoid osteoarthritis may accompany osteoarthritis of the CM joint of the thumb. If the scapho-trapezoid joint is not excised when performing an excision of the trapezium with ligament reconstruction and interposition of the tendon of the FCR, the procedure may be unsuccessful.

Example 2: Find the fourth angle of the right trapezium if one of the given angles is 60°. Solution: As we know, in a right trapezium, there are 2 right angles and the sum of all the interior angles in a trapezium is always 360°. So, if one of the given angles is 60°, let the missing angle be x°. The fourth angle can be calculated as x° + 90° + 90° + 60° = 360°. ⇒ x° = 360° - (90 ...

Trapezial space height, expressed as a percentage of the trapezial space height from the 3-month postoperative x-ray, represented the long-term metacarpal subsidence. Trapezial height was defined as the distance between the metacarpal base and the distal scaphoid or residual trapezium .

Because of the potential that scaphotrapezoid arthritis may cause residual symptoms following trapezium excision arthroplasty, and in light of the low sensitivity of radiographs, routine intraoperative assessment of the joint is recommended so that proximal trapezoid excision can be performed if degenerative change is present.

Firstly, subsidence was defined as the difference in ratio of cup height to trapezium height between the 2 time points (Fig. 2). Secondly, we inspected the cups for progressive tilting. Thirdly, on radiographs taken 2 weeks postoperatively, the size of any residual calcification was measured in millimeters relative to the distal rim of the cup.

A trapeziectomy is a surgery used to treat thumb arthritis when conservative treatments fail. It involves removing a bone in the wrist, called the trapezium, and replacing it either with a tendon from your own body or a metal or silicone implant.
