Rheumatoid forefoot reconstruction: Outcome of 1st metatarsophalangeal joint fusion and the Stainsby procedure in the lesser toes

BackgroundRheumatoid arthritis is a chronic inflammatory disease involving connective tissue and joints. The most common rheumatoid forefoot deformities are hallux valgus and clawed lesser toes. There are a number of surgical procedures that have been described offering symptomatic relief and anatomical correction.ObjectivesThis prospective case series aims to assess outcome in patients with rheumatoid forefoot deformities who underwent a novel combination of 1st metatarsophalangeal joint fusions and Stainsby procedures.MethodsThirteen procedures were performed on 12 consecutive patients with an age range of 55–71 (mean = 62) between 02/2009 and 05/2011. AOFAS scoring was performed preoperatively and again six and 12 months post-surgery. Hallux valgus (HVA) and intermetatarsal angles (IMA) were measured preoperatively and six weeks and six months postoperatively.ResultsThe mean AOFAS score increased from 46 to 72, 12 months postoperatively. The mean HVA reduced from 48° preoperatively to 14° six months postoperatively. The IMA decreased from 15° to 10° six months postoperatively.ConclusionsThe novel approach of 1st metatarsophalangeal fusion combined with lesser toe metatarsal head sparing is an effective procedure that reduces forefoot deformity and pain.     

Joint preserving surgery for rheumatoid forefoot deformities improves pain and corrects deformity at midterm follow-up

BackgroundRheumatoid arthritis is a chronic autoimmune disorder that commonly affects the metatarsophalangeal (MTP) joints. Conventional surgical treatment involves joint-sacrificing surgery to relieve pain and correct deformity.ObjectivesWe retrospectively reviewed 49 patients with rheumatoid forefoot deformities who underwent 66 joint preserving procedures with Scarf osteotomy of the first metatarsal and Weil's shortening osteotomy of the lesser metatarsals.MethodThere were 5 males and 44 females with mean age 56.1 years and mean follow-up 51 months. All patients were evaluated clinically and radiologically with hallux valgus angle (HVA) and inter-metatarsal angle (IMA).ResultsMean AOFAS score improved from 39.8 preoperatively to 88.7 at final follow-up. Subjectively patients reported their outcome as excellent in 49 feet (74%), good in 9 feet, fair in 7 feet and poor in 1 foot. Five feet had residual stiffness and 11 residual pain. Mean HVA and IMA decreased from 32° to 14° and from 15° to 11° respectively.ConclusionIn intermediate to severe stages of the disease, joint preserving surgery by Scarf osteotomy of the first MTP joint and Weil osteotomy of the lesser metatarsals may be performed as an alternative to joint-sacrificing procedures and should be considered as a complement to the various surgical treatments of the rheumatoid forefoot.

Long term efficacy of minimal incision osteotomy for hallux abducto valgus

Objective: To observe and evaluate the long‐term results of minimal incision osteotomy for hallux abducto valgus. Methods: From February 1995 to May 1999, 372 cases (705 feet) with hallux abducto valgus were treated with minimal incision osteotomy. Seventy‐nine patients (150 feet) were followed up for more than five years (mean 7.5; range, 5.3–13.2 years) after surgery. The preoperative and postoperative hallux abducto valgus angles (HVA), intermetatarsal angles (IMA), tibial sesamoid position (TSP), American Orthopaedic Foot And Ankle Society (AOFAS) score, range of movement of the first metatarsophalangeal joint and lateral metatarsalgia were observed, measured and evaluated. Results: Based on clinic curative effect evaluation criterion, 56 feet (37.3%) were excellent, 88 feet (58.7%) good, 6 feet (4.0%) fair. The postoperative mean AOFAS score was 84.20 ± 4.32 points. The mean HVA decreased from 33.28^o to 12.31^o and the mean IMA1‐2 from 11.75^o to 6.80^o. The TSP was corrected from an average preoperative grade of 4.29 to a grade of 3.07 by final follow‐up. There was no nonunion or delayed union, no avascular necrosis, no infection, and no hallux varus. Numbness in the big toe was found in 4 feet (2.7%). The range of motion of the first metatarsophalangeal joint decreased from 70.20^o to 69.53^o. Of 97 feet (64.7%) with pre‐operative 2–5 metatarsalgia, this had disappeared in 35 feet, improved in 54 feet and was aggravated in 8 feet postoperatively. Conclusion: Minimal incision osteotomy is a simple and reliable technique for treating hallux abducto valgus with minimal complications.     

Scarf and Weil osteotomies for correction of rheumatoid forefoot deformities: A review of 20 cases

The forefoot is commonly affected in rheumatoid arthritis. Little has been written of the results of metatarsophalangeal joint preservation in rheumatoid arthritis. We describe the results of the Scarf and Weil osteotomy for correction of forefoot deformities in patients with rheumatoid arthritis. Between 1996 and 1999, 17 patients (20 feet) underwent a Scarf osteotomy for their hallux valgus deformity and in 17 feet a Weil osteotomy of the lesser metatarsophalangeal joints. Radiographic examination was performed preoperatively and at a mean follow up of 65 months. A questionnaire was used at a minimum follow up of 6 years. The hallux valgus angle improved from 41° to 28° at follow up. The majority of the patients (79%) were satisfied with the result during follow-up. We found no wound infections, neuralgia or osteonecrosis of the first metatarsal. In three patients, a fusion of the first MTP joint was performed at follow up.In conclusion, the Scarf and Weil osteotomy is a useful method for MTP joint preserving surgery in rheumatoid forefoot deformities without severe impairment of the MTP joints.     

Fusion of the first metatarsophalangeal joint in forefoot arthroplasty

Forefoot arthroplasty is often recommended for the management of metatarsalgia secondary to rheumatoid arthritis. Concurrently, the first metatarsophalangeal (MP) joint can be fused rather than excised. The results in 37 patients with 64 arthroplasty operations (34 with fusion and 30 with excision of the first joint) show that fusion produced a better cosmetic appearance of the foot, facilitated fitting with normal shoes, and improved overall balance. Pedobarograph measurements during gait indicated that relatively more weight was transmitted through the medial ray when the first metatarsophalangeal joint was fused. Residual pain in the foot was often caused by irregular trimming of the metatarsals. There was no difference in relief of pain between fused and unfused patients. Failure of fusion at the first metatarsophalangeal joint generally was painless. Radiologic degeneration of the interphalangeal (IP) joint of the great toe was relatively common following fusion. MP joint fusion is inadvisable if there is already disease in the IP joint.     

Fusion of the First Metatarsophalangeal Joint and Second to Fifth Metatarsal Head Resection for Rheumatoid Forefoot Deformity

The goals of the present study were to evaluate the mid-term results of first metatarsophalangeal joint fusion combined with second to fifth metatarsal head resection in rheumatoid forefoot deformity and identify the prognostic factors. The inclusion criteria were 2010 American College of Rheumatology and/or European League Against Rheumatism criteria for rheumatoid arthritis; symptomatic forefoot deformity; first metatarsophalangeal joint fusion and second to fifth metatarsal head resection; and a minimum of 4 years of follow-up data available. The patients were evaluated using the Disease Activity Score 28 for rheumatoid arthritis, Health Assessment Questionnaire for Rheumatoid Arthritis, Foot Function Index, forefoot American Orthopaedic Foot and Ankle Society scale, and weightbearing radiographs. Different pre-, intra-, and postoperative variables were investigated to identify the prognostic factors. Sixty-two patients (89 feet) with a mean age of 60.8°± 9.4 years and 85.5°± 22.4 months of follow-up data were included. The preoperative American Orthopaedic Foot and Ankle Society scale score was 33.4 ± 16 points and improved significantly (p < .001) after surgery (mean 82.9 ± 11.7 points). The mean Foot Function Index improved significantly (p < .001) from 131.6 ± 37.4 to 77.4 ± 46.3 points at the last follow-up visit. Only the revision surgery variable was significantly (p = .02) related to poor outcomes. Revision was necessary in 8 feet (9%). This procedure produced satisfactory results. Poor outcomes were significantly related to the necessity for revision surgery for nonunion, malunion, inadequate metatarsal resection, and painful hardware.

目的 评价微创截骨治疗(足母)外翻的远期疗效.方法 对1996年2月至1999年5月在我院行微创截骨治疗的(足母)外翻患者进行回顾性分析,共79例(150足)获得5年以上随访,男6例(10足),女73例(140足);年龄13～75岁,平均47岁.术后随访5.3～13.2年,平均7.5年.观察手术前、后(足母)外翻角(hallux valgus angles,HVA),第一、二跖骨间角(intermetatarsal angles,IMA),胫侧籽骨位置(tibial sesamoid bone position,TSP),(足母)趾-跖趾-趾间关节美国足与踝关节协会(American orthopedic foot and ankle society,AOFAS)评分,第一跖趾关节活动度和第二、三跖骨头下胼胝体(肼胝痛)等指标.根据温建民等的临床疗效评价标准(2001年)对临床疗效进行评价.结果 临床疗效评价优56足,占37.3%;良88足,占58.7%;差6足,占4.0%;优良率为96.0%(144/150).术后AOFAS评分为60～100分,平均(84.20±4.32)分.HVA较术前矫正20.97°;IMA较术前矫正4.95°;TSP较术前矫正1.22;第一跖趾关节活动度减少0.67°.术前合并有跖骨头下疼痛97足,占64.7%.术后疼痛消失35足(23.3%),疼痛改善54足(36.0%),疼痛无改善(或加重)8足(5.3%).结论 微创截骨治疗(足母)外翻方法简单、并发症少、远期疗效肯定,是治疗(足母)外翻的一种较好的、疗效可靠的手术方法.
