Results of JESS (Joshi's External Stabilizing System) in Relapsed, Neglected and Neurogenic Clubfoot in an Age Group of 2-10 Years.

BACKGROUND

Joshi's External Stabilization System (JESS) is an external fixator based methodology to correct different deformities of club foot using differential distraction.

MATERIAL AND

METHODS

31 difficult clubfeet feet in 24 patients who were neglected, neurogenic or relapsed were treated using JESS between July 2013 to June 2015 with an average follow-up of 4. 2 years. There were 16 males and 8 females in an age group of 2-10 years. 30 feet belonged to the severe and most severe group as per the Dimeglio Scoring System. All patients achieved correction of all components of the clubfoot.

RESULTS

However, one patient required tibialis anterior transfer for dynamic forefoot adduction at the end of treatment. The mean total duration in JESS fixation was 69.5 days/foot (range 44-123 days) and the mean time to achieve correction within JESS averaged 52 days. The deformities improved from a mean Dimeglio score of 14.06 to 2.93. The objective radiological assessment of the deformities revealed improvements in the talocalcaneal angle on AP view from 16.39° to 34.52° and on lateral view from 15.97° to 33.03°. The Talo-1st metatarsal angle (AP view) improved from 35.29° to 7°. Complications included 11 cases of superficial pin tract infection, two instances of pin loosening and a case of pin cut out. There were three cases of 1st metatarsophalangeal dislocation that were managed by reversing the process of distraction.

CONCLUSION

JESS is an effective method for managing difficult clubfeet.
