The Windblown hand
Red Cross Childrens Hospital Experience 2003-2011
Dr Steve Carter
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”
History• Wood,Biondi (1990) J Hand Surg 15A:431-38
20 yr study 11 patients operated on 7 hands in 4 patients• Gavaskar,Chowdary(2009) J Child Orthop 3:109-114
7 yr study operated on 23 hands in 18 patients
• Mc Carrol,Manske (1992) Hand Clin 8:147-59
25 yr study operated on 29 thumbs in 18 patients
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
Surgery LiteratureMcCarroll
Pathology Surgical procedure
Thumb Contracture First 15 years volar release and extensor transfer – poor resultsNext 10 years volar release and MCP Arthrodesis
Ulna deviation of digits
nil
Volar flexion contracturre
nil

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
Patients
Gender Age Uni/Bilat Pathology Surgery
Female 3 Bilat Digitotalar Thumbs only bilat
Male 2 Bilat Windblown R ThL Th and crossed intrinsic
Male 2 Bilat Windblown R Th
Male 3 Bilat Windblown R ThL Th and crossed intrinsic
Male 2 Bilat Windblown R ThL Th
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
