7. The Trapezium
Surfaces
1.Palmar Surface-Groove and a Tubercle.
2.Dorsal Surface-Related to Radial Artery.
3.Lateral Surface-Lateral collateral ligament
of the wrist joint & capsular ligament of
the carpometacarpal joint.
4.Medial Surface-Facet for the Trapezoid.
5.Proximal Surface-Facet for the Scaphoid.
6.Distal Surface-Saddle shaped for the base of the
first metacarpal.
10. Intercarpal Joints
1.Joints between bones of the proximal row.
2.Joints between bones of the distal row.
3.Midcarpal Joint
- Between these two rows of bones.
- S shaped cavity lined by synovial
membrane.
- Has 2 projections proximally and
3 projections distally.
18. Pathology
Stage IV:
Subluxated metacarpal fixed by fibrosis &
contracture
Marked hyperextension deformity of the MCP joint
Flexion deformity of the IP joint
Pain minimal or nil
Fixed adducted thumb

26. Excision of the Trapezium
Gervis(1949) 18 wrists with 16 good results.
(1973) 12 wrists followed up for 6 to 22 years.
Goldner & Clippinger(1955) Excison of the
Trapezium piece-meal.
Murley(1960) 39 wrists with 36 good results.
Marmor & Peter(1969) 7 wrists with 5 good
results.
Sims & Bentley(1970) 27 Trapeziectomies with
excellent results in 15,Good in 6,Fair in 5 & Poor
in one.Incidence of 54% of patients with
associated Trapezio-Scaphoid Arthritis.
47. Results
Functioning tendons of Flexor carpi radialis
and Flexor pollicis longus =26/26 wrists.
Decreased sensations over the dorsum of
the base of the thumb =3/26 wrists.
Keloid formation = 5/26 wrists.
Palpable Neuroma = None.
58. Radiographic Features
5.Residual Cartilage:
Base of first MC – Nil in 3 wrists
- Present in 22 wrists
Distal Scaphoid - Nil in 2 wrists
- Present in 23 wrists
6.Lateral subluxation of 1st MC on Abduction
Marked subluxation in 3 wrists
Moderate subluxation in 22 wrists
59.
60. Radiographic Features
7.Maintenance of joint space despite subluxation of
the 1st MC on the Scaphoid on radial deviation of
the wrist.
8.Stress views of the wrist:
No changes
= 9 wrists
Widening of the Sc-Trap.Jt
=12 wrists
Widening of the Sc-Cap.Jt
= 6 wrists
Widening of gap between
the bases of 1st & 2nd MC’s = 6 wrists
67. Arthrographic Assessment
1.Amount of dye injected.
2.Ease of location of the joint & injection.
3.Residual articular cartilage over:
-Base of the first metacarpal.
-Distal Scaphoid.
76. Conclusion
1.Excision of the Trapezium gives good
results with respect to relief of pain.
2.Good hand function despite some reduction
in the power of Opposition grip and Pinch
grip.
3.Carpal Instability or Laxity may account for
decreased Opposition grip & Pinch grip.
77. Conclusion
4.Arthrographic Features:
-Distinct joint space
-Small & Irregular within 6 months of
Surgery
-Large & Regular thereafter
-Marked subluxation indicates weak grip
5.Late deterioration of pseudoarthrosis in one
patient
