Purpose: The aim of this study was to retrospectively evaluate the clinical and radiological results of the first metatarsophalangeal joint arthrodesis with two crossed screws fixation. Materials and Methods: We treated 23 patients (24 cases) with arthrodesis of the first metatarsophalangeal joint using two crossed screws fixation between December 2000 and May 2005. There were 3 male patients and 20 female patients. Ages ranged from 28 to 74 years (mean, 50 years). Follow-up ranged from 4.1 to 8.2 years (mean, 6.5 years). The American Orthopaedic Foot and Ankle Society (AOFAS) score and their satisfaction was evaluated clinically, foot anteroposterior and lateral radiograph, radiologically. Results: Of the 24 cases, 6 had surgery for dorsal plate and screws fixation because of failure to acquire firm fixation with two crossed screws fixation. All 6 cases acquired bony union. Fusion of the hallux first metatarsophalangeal joint occurred in 16/18 cases (89%). Nonunion occurred in 2 cases (11%) and was asymptomatic. At last follow-up, hallux valgus angle ranged from 11 to 25 degrees(mean, 17.7 degrees), dorsiflexion ranged from 15 to 25 degrees (mean, 22 degrees).The mean preoperative AOFAS score of 37 points(range, 28 to 45 points) improved to a mean of 77 points (range, 65~90 points) postoperatively. The result of the procedure as rated subjectively by the patient was excellent for 5 cases, good for 11 cases and fair for 2. Conclusion: Comparatively, the arthrodesis of the first metatarsophalangeal joint with crossed screws fixation showed a satisfactory clinical results, we thought that require technical attention for firm fixation in operation.

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 $44.1{\pm}7.1$ and $15.5{\pm}6.2$ degrees to $13.6{\pm}2.6$ and $10.2{\pm}2.2$ degrees respectively. The dorsiflexion angle was measured in $20.3{\pm}3.7$ 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.

Surgical treatments for arthritis in the first metatarsophalangeal joint include arthrodesis, interposition arthroplasty using silicone or meniscus cartilage, and rarely arthroplasty. Although arthrodesis was performed successfully, pain can persist if the angle of fusion was inappropriate. Interposition arthroplasty can be tried for the treatment of persisting pain after the arthrodesis. Interposition arthroplasty using tensor fascia lata is known that has low risk of adhesions and easy to harvest. Compared to autologous grafts, grafting rates is high and low risk of rejection additionally. Herein, we report a successfully managed arthritis with severe pain with interposition arthroplasty using tensor fascia lata after a failed metatarsophalangeal joint arthrodesis.

Purpose: We assess the mid to long term follow up results of arthrodesis of the first metatarso-phalangeal (MTP) joint and resection arthroplasty of the lesser toes in rheumatoid arthritic forefoot deformity. Materials and Methods: Between 1998 to 2001 year, 25 cases (18 patients) rheumatoid forefoot deformities were surgically corrected. Follow up period was 83 months (range, 63 to 90 months). The clinical outcome was evaluated using subjective satisfaction and AOFAS score. The radiological measurements were hallux valgus angle, first and second intermetatarsal angle, second metatarso-phalangeal angle (MTP-$2^{nd}$ angle). Results: Subjective satisfaction was 76%. AOFAS score improved from 37 to 73. The hallux valgus angle improved from preoperative $39^{\circ}$ ($27{\sim}64^{\circ}$) to $14^{\circ}$ ($4{\sim}34$) at the last follow up. The intermetatarsal angle were preoperative $13^{\circ}$ ($6{\sim}22^{\circ}$) to $11^{\circ}$ ($3{\sim}13^{\circ}$) at the last follow up, The MTP-$2^{nd}$ angle were preoperative $24^{\circ}$ ($9{\sim}47$) to last follow up $15^{\circ}$ ($2{\sim}39^{\circ}$) respectively (p>0.05). Complication was intractable callus 10 cases, Interphalangeal arthritis 5 cases. Conclusion: Mid to long term outcomes rheumatoid forefoot reconstruction by first MTP arthrodesis and resection arthroplasty of lesser toes results a satisfaction and pain relief.

Hallux valgus is a deformity characterized by lateral deviation of the great toe and medial deviation of the first metatarsal. When planning an operative treatment, it is important to realize that the deformity is tridimensional and diverse. Operative techniques include medial eminence resection, distal soft tissue procedure, first metatarsal osteotomy (distal, diaphyseal, proximal, or multiple), proximal phalanx osteotomy, arthrodesis (first metatarsophalangeal or metatarsocuneiform joint), and so on. Among these techniques, osteotomy is the main procedure for correcting the hallux valgus. The objective of this article is to describe the characteristics and recent advancements made for corrective osteotomies in the hallux valgus. The pathophysiology of the hallux valgus is also described.

Although many patients who undergo bunion repair do well and have satisfactory results, a critical evaluation of these results shows the potential for improvement. Metatarsal deformity of the hallux valgus is a 3-dimensional deformity, including rotation in the coronal plane. Theoretically, it is important to understand the 3-dimensional displacement of the first metatarsal for correcting the deformities of valgus rotation in the frontal plane. Yet the current methods of metatarsal osteotomy principally attempt to correct the deformity in the transverse plane. The modified technique for the Lapidus procedure can be used in a variety of hallux valgus conditions and severities, and the early results suggest that a powerful correction can be maintained. In addition, efforts have been made to correct the 3-dimensional deformity by performing metatarsal shaft osteotomy. In the case of degenerative arthritis, first metatarsophalangeal joint arthrodesis is a good option to correct the 3-dimensional deformation. Correction of the 3-dimensional deformity, including a rotational deformity in the frontal plane of the metatarsals, should be considered when selecting surgical treatment and is essential for achieving a good prognosis for patients with hallux valgus. This article reviews the classification and treatment of hallux valgus for correction of the 3-dimensional deformity.
