Introduction• Congenital ulna drift first described by Boix in 1897• Extremely rare• Three essential features
1. Thumb adduction and flexion contracture
2. Ulna drift of the fingers at the metacarpophalangeal joint
3. Flexion contracture of fingers

Aetiology• Zancolli and Zancolli (1985) – Segmental Arthrogryposis• Associations – Freeman Sheldon Syndrome
(Craniocarpotarsal dysplasia)
- Digitotalar dysmorphism• Red Cross – Syndromic or Idiopathic (MCP Dysplasia)
-” Extensor Failure theory”

Surgery LiteratureBiondi and Gavaskar
Pathology Surgical procedure
Thumb Contracture Z plasty,Dorsal rotation Flap,Adductor release as necessary.EIP Transfer to supplement extension
Ulna deviation of the Digits
Recentralize extensor tendonRelease or transfer ulna intrinsic
Volar flexion contracture fingers
Full thickness skin graft

RXH Experience
• 9 years (2003-2011) 10 Patients• 5 patients Operated on 9 hands • 5 patients not operated on – 1 Mother
- 2 males Bilateral hands 16 yrs old functional
- 2 males Bilateral awaiting surgery

Results• Wood and Biondi 1991 classification based on cosmesis and
function• Evaluation subjective, hard set of criteria unrealistic• Excellent – Normal function and cosmesis• Good – Almost normal function,satisfactory appearance• Fair - Some contractures that interfere with function• Poor – Contracted hand no function
• Rxh 7 good results and 2 fair results in 9 hands

Conclusions• Priority is treatment of thumb deformity –Volar release, stability MCP
and extensor transfer
• Extensors are the problem therefore need EIP transfer
• Intrinsic transfer improves appearance but not necessarily function
• No volar grafting
• Early surgical management < 2rs
