- Abstract
We investigated the clinical outcomes of surgical procedures for the treatment of forefoot deformities in patients with rheumatoid arthritis. Twenty feet in 16 women (mean age 62.1 years) underwent corrective osteotomy of the first metatarsal bone with shortening oblique osteotomy of the lesser metatarsophalangeal joints (joint-preservation group), while 13 feet in 12 women (mean age 67.4 years) underwent arthrodesis of the first metatarsophalangeal joint with resection arthroplasty of the lesser metatarsophalangeal joints (joint-sacrifice group); mean follow-up for each group was 25.8 and 23.8 months, respectively. The mean total Japanese Society for Surgery of the Foot (JSSF) scale improved significantly from 64.2 to 89.2 in the joint-preservation group (p <.001), and from 54.2 to 74.2 in the joint-sacrifice group (p =.003). In the joint-preservation group, the postoperative range of motion (ROM) of the joint, walking ability, and activities of daily living scores of the JSSF scale were significantly higher than those in the joint-sacrifice group (p =.001, p =.001, and p =.019, respectively). There were no differences in the subscale scores of the self-administered foot evaluation questionnaire between 2 groups either pre- or postoperatively. No differences in the postoperative complications were found between 2 groups. Although the joint-sacrificing procedure resulted in lower objective outcomes than the joint-preserving procedure regarding the ROM of the joint, the walking ability, and the level of activities of daily living, both procedures resulted in similar treatment outcomes when evaluated by the subjective measures.

- Abstract
Background: We investigated the clinical outcomes of resection and joint-preserving arthroplasty for forefoot deformities in patients with rheumatoid arthritis. Methods: Sixteen feet of 14 women (average age, 67.1 years; range, 53-82) underwent resection arthroplasty of the metatarsal head (resection group), and 18 feet of 15 women (average age, 61.3 years; range, 40-73) underwent a metatarsophalangeal joint-preserving procedure with shortening oblique metatarsal osteotomies of the lesser toes (joint preservation group). The mean disease duration in the resection and joint preservation groups was 23.6 and 19.1 years, and the average follow-up period was 37.3 and 33.5 months, respectively. The classification of Larsen was used to assess the severity of destruction of the metatarsophalangeal (MTP) joint. Preoperative and postoperative clinical evaluation included Japanese Society for Surgery of the Foot (JSSF) score and postoperative complications. Results: The number of preoperative radiographic destruction of the MTP joints (Larsen grade II, III, IV, and V) was 0, 29, 39, and 12 joints in the resection group and 13, 67, 9, and 1 joints in the joint preservation group. The mean JSSF score improved significantly from 61.3 to 83.9 points in the resection group (P < .001) and from 62.2 to 90.8 points in the joint preservation group (P < .001). In the resection group, recurrence of callosities and claw toe deformity was observed in 6 and 3 feet, respectively. In the joint-preserving group, recurrence of callosities and hammer toe deformity was observed in 1 foot each. Conclusion: The resection arthroplasty and joint-preserving procedure showed satisfactory clinical outcomes. However, whether both procedures can maintain the good clinical results without the recurrence of forefoot deformity will require longer follow-up. Level of Evidence: Level III, retrospective comparative series. [ABSTRACT FROM AUTHOR]

- Abstract
Background: We aimed to evaluate the early clinical results of the reconstruction of problematic elbow joints due to rheumatoid arthritis (RA) using a PROSNAP linked elbow prosthesis (Kyocera Medical, Osaka, Japan) for total elbow arthroplasty. Methods: Seventeen elbows in 14 RA patients were replaced with a PROSNAP elbow with cement fixation. The patients comprised 1 man and 13 women, with a mean age of 63.9 years (range, 52-83 years) at the time of surgery. The preoperative conditions of the elbows were arthritis mutilans (n = 10), an ankylosed or stiff elbow with a preoperative range of motion of 45° or less (n = 4), and loosening of a primary total elbow arthroplasty (n = 3). The mean follow-up period was 47.7 months (range, 32-69 months), with a 100% follow-up rate. The clinical outcome of the elbows was evaluated by the Mayo Elbow Performance Index (maximum, 100 points). Results: The mean postoperative Mayo Elbow Performance Index score improved from 57.6 points to 97.1 points. Preoperatively, 3 of the 17 elbows were judged as good, 7 as fair, and 7 as poor; at final follow-up, 16 elbows were judged as excellent and 1 as good. Complications were noted in 1 elbow (6%), which had undergone a postoperative fracture. Conclusions: The PROSNAP elbow prosthesis can be safely implanted through a relatively easy procedure and provides satisfactory short-term clinical outcomes for the reconstruction of severely damaged RA elbows.

- Abstract
Purpose We investigated objective and patient-reported outcomes after resection arthroplasty or shortening oblique osteotomy (SOO) of the lesser metatarsals combined with arthrodesis of the first metatarsophalangeal (MTP) joint for severe rheumatoid forefoot deformities.Methods 17 feet from 14 women (mean age, 67.8 years) underwent resection arthroplasty of the lesser metatarsal heads (MTH resection group), while 13 feet from nine women and two men (mean age, 68.7 years) underwent SOO of the lesser metatarsals (MTH preservation group). Arthrodesis of the first MTP joint was performed in all cases. Mean follow-up in the MTH resection and preservation groups was 25.0 and 21.3 months, respectively. Preoperative and postoperative clinical evaluation included Japanese Society for Surgery of the Foot (JSSF) scale and self-administered foot evaluation questionnaire (SAFE-Q) scores.Results Mean total JSSF scale significantly improved from 53.4 to 76.4 in the MTH resection group (p< .001) and from 50.1 to 74.2 in the MTH preservation group (p= .002). Pain and pain-related and shoe-related SAFE-Q subscale scores significantly improved after surgery in both groups. In the MTH resection group, recurrence of painful callosities and claw toe deformity was observed in four and three feet, respectively. In the MTH preservation group, one patient experienced recurrence of painful callosities and one underwent revision surgery for IP joint dislocation.Conclusion Resection arthroplasty or SOO of the lesser metatarsals combined with arthrodesis of the first MTP joint achieved significant improvement with respect to pain relief, deformity correction, and footwear comfort.
