Abstract:

To preserve the function of metatarsophalangeal joints and to ensure forefoot stability in patients with rheumatoid arthritis (RA), we performed a modified Hohmann method for hallux valgus (HV) and telescoping osteotomy of lesser toe deformities instead of fusion of HV or resection of all metatarsal heads. From October 1995 through March 2001, 47 RA patients (90 feet) with severe HV and forefoot deformities were examined. The indication for the procedure in all the patients was disabling foot pain secondary to intractable plantar callosities below the lesser metatarsal heads, painful HV deformities, and the severe deviation of the sesamoid complex diagnosed by the basis of X-ray images. The HV and intermetatarsal (M1M2 and M1M5) angles and sesamoid complex were measured on the preoperative and postoperative roentgenograms. According to the results of a questionnaire survey, the patients were divided into three groups using the visual analogue scale; group 1: satisfied, group 2: fair and or no pain, group 3: dissatisfied. HV and M1M2 angles significantly improved compared between pre- and postoperative or preoperative and the follow-up periods. Out of the 47 patients, 78.9% were satisfied with the results of the operation and 8.9% were dissatisfied. Of these patients, 12.2% reported fair results. There were several complications, such as painful callosity, which was recurrent in seven feet, and delayed wound healing was observed in two out of 90 feet. A modified Hohmann method and abductor hallucis correction are effective in relieving pain and ensuring the bony union of the great toe in spite of severe osteoporosis.
