Results: The average differences in trapezium height and M1-M2 ratio pre- and post-surgery were, respectively, 1.8 mm (SD ± 1.7; p < 0.001) and 0.04 mm (SD ± 0.04; p = 0.017). Pre-to-postoperative M1 axis length increased by an average of 2.98 mm (SD ± …

Trapezium and Bennett Fracture – A Rare Base Thumb …

Trapezium fracture is a rare entity whose treatment is controversial. The reported cases range from conservative treatment to surgical treatment with good reported results. ...

Trapeziectomy: Preparation, Recovery, Long-Term Care

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.

Long-Term Results of Suture-Button Suspensionplasty in the …

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 .

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.

Trapezium

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 ...
