Purpose:To investigate the short term result of the first metatarsophalangeal arthrodesis for treating the hallux valgus deformity of rheumatoid arthritis, using a lag screw and dorsal mini-plate.
Materials and Methods:From December 1999 to September 2001. The first metatarsophalangeal arthrodesis of 14 cases (9 patients) was underwent, using a lag screw and dorsal mini-plate. The follow-up period was averaged in 14.6 months. The subjective findings with respect to pain, functional aspect of ability to stand and walk, and to shoe-wearing were evaluated. The objective findings, such as the gross alignment and the radiological measurements for the hallux valgus angle, 1,2 intermetatarsal angle, and dorsiflexion angle were also studied.
Results: After the arthrodesis of the first metatarsophalangeal joint, the subjective improvement in pain, function and alignment was graded as excellent in seven (50%) feet, good in seven (50%) feet, and fair or poor in none. The hallux valgus angle and 1,2 intermetatarsal angle were reduced from 44.1±7.1 and 15.5±6.2 degrees to 13.6±2.6 and 10.2±2.2 degrees respectively. The dorsiflexion angle was measured in 20.3±3.7 degrees after the fusion. The radiological fusion was observed at average 8 weeks after the operation in all cases. The overall complication of the procedure was few, except the delayed wound healing in one.
Conclusion:The arthrodesis of the first metatarsophalangeal joint using a lag screw and dorsal mini-plate was regarded as an excellent method of various operative modalities to correct the rheumatoid hallux valgus deformity.
