Flexion Deformities of the Wrist and Fingers in Spastic Cerebral Palsy: A Protocol of Management.

BACKGROUND

Literature is confusing regarding grading and treatment of flexion deformities of wrist and fingers in spastic cerebral palsy (CP). The most established classification is that described by Zancolli; unfortunately, it has its shortcomings which we experienced in the beginning of our approach to manage this rather difficult deformity. We thus modified Zancolli's classification and developed a classification system and treatment protocol.

MATERIALS AND METHODS

Thirty patients with spastic CP were operated upon due to flexion deformity of the wrist and fingers and were included in this study. Age ranged from 4 to 14 years, average 7 years. There were twenty boys and ten girls.

RESULTS

The average followup was 18 months (range 9 months - 3 years). The power of wrist dorsiflexion, the "House's classification of upper extremity functional use" and the clinical assessment of hand function were used for evaluation; they improved in all patients and this improvement was statistically significant. In all patients, cosmetic appearance improved without any residual flexion deformity.

CONCLUSION

This study introduces a new grading system for flexion deformity of wrist and fingers in spastic CP that correlates with severity of the condition and allows a treatment protocol to be established.
