Objective To evaluate the clinical effectiveness of the first metatarsophalangeal (MTP) joint arthroplasty versus arthrodesis for rheumatoid forefoot deformity. Methods The randomized controlled trials (RCTs) about the first MTP joint arthroplasty vs. arthrodesis for rheumatoid forefoot deformity published by February 2012 were searched in the databases such as CNKI, Ovid, MEDLINE, CBM, EMbase, WanFang Data, The Cochrane Library (Issue 1, 2012), and KJEBM. Two reviewers independently screened studies, extracted data, and evaluated the methodological quality according to the inclusion and exclusion criteria. Then meta-analysis was conducted using RevMan 5.1 software. Results A total of 4 RCTs were included. Among total 206 (269 feet) patients involved in, 98 (130 feet) were in the arthroplasty group, while the other 108 (139 feet) were in the arthrodesis group. The results of meta-analysis showed that the arthrodesis group was superior to the arthroplasty group in the footwear (MD=−0.88, 95%CI −1.55 to −0.22, P=0.01), and the alignment (MD=−5.04, 95%CI −8.94 to −1.14, Plt;0.000 01) with significant differences. But there were no significant differences between the two groups in patient satisfaction, metastatic lesions, pain, activity and weight-bearing of Hallux. Conclusion Based on the current studies, arthrodesis is superior to arthroplasty in treating rheumatoid forefoot deformity. For the quality restrictions and possible publication bias of the included studies, more double blind, high quality RCTs are required to further evaluate the effects.
Objective To explore perioperative management and postoperative effectiveness of hemophilia induced lesions of the foot and ankle. Methods Between June 1998 and February 2012, 10 cases (12 feet) of hemophilia induced lesions of the foot and ankle were treated with surgery, including 9 cases (11 feet) of hemophilia A and 1 case (1 foot) of hemophilia B. Single foot was involved in 8 cases and both feet in 2 cases, including 3 left feet and 9 right feet. All were males, aged from 13-41 years (mean, 22.6 years). Disease duration was 5-84 months (mean, 32.2 months). Preoperative American Orthopaedic Foot and Ankle Society (AOFAS) score was 43.2 ± 21.1. Short Form 36 Health Survey Scale (SF-36) score was 45.4 ± 20.0. All patients were given clotting factors (2 000-3 500 U) for pre-experiment and clotting factors substitution therapy was performed perioperatively. Four cases (4 feet) underwent arthrodesis, and 7 cases (8 feet) underwent Achilles tendon lengthening/tendon transposition (1 patient underwent tendon lengthening on the left foot and arthrodesis on the right foot). Results The operation time was 65-265 minutes (mean, 141.1 minutes); 1 case had 400 mL blood loss and 200 mL autogenous blood transfusion, the other cases had less than 50 mL blood loss and no blood transfusion. Wounds healed by first intention in all patients, no postoperative infection, deep vein thrombosis, or other complications occurred. All cases were followed up 6 months to 14 years and 3 months (median, 22 months). The X-ray films at last follow-up showed the patients undergoing arthrodesis obtained complete joint fusion. AOFAS scores at postoperative 6 months and last follow-up were 78.8 ± 14.7 and 75.8 ± 14.5, respectively; SF-36 scores were 76.6 ± 13.1 and 75.5 ± 13.2, respectively; and significant differences were found when compared with preoperative scores (P lt; 0.05), but no significant difference between postoperative 6 months and last follow-up (P gt; 0.05). Conclusion For patients with hemophilia induced lesions of the foot and ankle, surgical treatment could relieve foot and ankle pain and improve the function. Clotting factors pre-experiment at preoperation and substitution therapy at perioperation can reduce the risk of severe postoperative hemorrhage.
Objective To compare the effectiveness of arthroscopic and open ankle arthrodeses. Methods The clinical data were retrospectively analyzed from 30 patients undergoing unilateral ankle arthrodesis between January 2008 and January 2011. Of 30 patients, 14 underwent arthroscopic ankle arthrodesis (arthroscopic group), and 16 underwent open ankle arthrodesis (open group). There was no significant difference in gender, age, lesion type, disease duration, and preoperative American Orthopaedic Foot and Ankle Society (AOFAS) score between 2 groups (P gt; 0.05). The operation time, intraoperative blood loss, postoperative hospitalization days, postoperative AOFAS score, and bony union rate were observed to evaluate the effectiveness. Results The operation time of arthroscopic group was significantly longer than that of open group (P lt; 0.05); the intraoperative blood loss and postoperative hospitalization days of arthroscopic group were significantly less than those of open group (P lt; 0.05). Superficial infection of incision occurred in 1 case of open group, and healing of incision by first intention was obtained in the other patients. All patients were followed up 12 months. No screw breakage was observed. The X-ray films showed bony fusion in 13 cases (92.86%) of arthroscopic group and in 10 cases (62.50%) of open group at 3 months after operation, showing significant difference (χ2=3.850, P=0.049); but no significant difference was found (χ2=0.910, P=0.341) in bony fusion rate between the arthroscopic group (14/14, 100%) and open group (15/16, 93.75%) at 12 months after operation. The AOFAS scores at 1, 3, 6, and 12 months after operation were significantly higher than preoperative score in 2 groups (P lt; 0.05). There was no significant difference in AOFAS score between 2 groups at 1 and 3 months (P gt; 0.05), but significant differences were found at 6 and 12 months (P lt; 0.05). Conclusion The overall effectiveness of arthroscopic ankle arthrodesis is better than that of open ankle arthrodesis, which can decrease intraoperative blood loss, shorten hospitalization days, get higher bony fusion rate, and obtain good ankle function recovery.
Objective To review the latest research progress of fixation techniques of ankle arthrodesis.Methods The l iterature concerning the research of fixation techniques of ankle arthrodesis in recent years was reviewed. Then the characteristics and new research progress of different internal and external fixation techniques were analysed and compared. Results There are plenty of different types of internal and external fixation devices, each with distinct characteristics. Now it is widely considered that internal fixation is the first choice for end-stage ankle arthropathy. However, under the circumstances that patients with serious bone defect, chronic active infection, or extensive soft tissue damage are not suitable for internal fixation, ankle arthrodesis with external fixation is still a safe and effective method. Conclusion For severe or end-stage ankle arthropathy, ankle arthrodesis is a mature therapeutic way with exact effect. Researches on these two aspects, expansion of indications of internal fixation and comparison and combination of internal and external fixation techniques, need to be deepened, which is of great significance for choosing a better fixation method and acquiring a better therapeutic effect.
Objective To discuss the effect of the calcaneocuboid arthrodesis on three-dimensional kinematics of talonavicular joint and its clinical significance. Methods Ten freshfrozen foot specimens, three-dimensional kinematics oftalonavicular joint were determined in the case of neutral position, dorsiflexion, plantoflexion, adduction, abduction, inversion and eversion motion by meansof threedimensional coordinate instrument（Immersion MicroScribe G2X） before and after calcaneocuboid arthrodesis under non-weight with moment of couple, bending moment, equilibrium dynamic loading. Calcaneocuboid arthrodesis was performed on these feet in neutral position and the lateral column of normal length. Results A significant decrease in the three-dimensional kinematics of talonavicular joint was observed（P＜0.01）in cadaver model following calcaneocuboid arthrodesis. Talonavicular joint motion was diminished by 31.21%±6.08％ in sagittal plane; by 51.46%±7.91％ in coronal plane; by 36.98%±4.12％ in transverse plane; and averagely by 41.25%±6.02％. Conclusion Calcaneocuboid arthrodesis could limite motion of the talonavicular joints, and the disadvantage of calcaneocuboid arthrodesis shouldn’t be neglected.
Objective To evaluate the effect of triple arthrodesison treating complications of calcaneus fractures. Methods From 1990to 2001, 12 patients with the complications of calcaneus fractures underwent the triple arthrodesis(subtalar,talaronavicular and calcaneocuboid joints). Ollier incision was applied to all patients. Peroneal tenolysis was required in 2 patients and a decompression and transposition of tibialnerve in 1 patient.Of the 12 patients, 7 were males and 5 were females. Their ages ranged from 29 to 64 years. Complications, like pain and deformity, occurred 5 to 22 months after the operation(18 months on average).Preoperative score, fibulocalcaneal distance, Bohler angle, differenceof talardeclination angle and height of hind foot were 40.00±5.22, 0.41±0.03 cm, 12.00±3.40°, 17.00±3.32° and 4.12±0.35 cm respectively. Results All patients were followed up from 3 to 13 years with an average of 7 years. Postoperative score, tibulocalcaneal distance, B[AKo¨]hler angle, difference of talar declination angle and height of hind foot were 75.00±6.46，0.73±0.02 cm， 31.00±5.61°，9.00±3.15° and 6.75±0.62 cm respectively. There were significant differences in these indexes(P＜0.05). Conclusion To evaluate the complications of calcaneus fractures and to adopt proper operative procedures are necessary. To restore theheight of hind foot and the anatomical relationship between hind foot and calcaneus is the key factor to success.
ObjectiveTo investigate the effectiveness of double arthrodesis to correct flatfoot deformity with pes valgus. MethodsBetween May 2009 and May 2012, 12 patients with flatfoot deformity and pes valgus were treated using subtalar and talonavicular joints arthrodesis through a single medial incision approach. There were 5 males and 7 females with an average age of 53.3 years (range, 21-78 years), including 5 left feet and 7 right feet. Of them, 11 cases had posterior tibial tendon dysfunctions; 6 cases were at Johnson-Strom stageⅢ, 5 cases at stageⅡ(c); and 1 case had tarsal coal ition. Preoperative American Orthopaedic Foot and Ankle Society (AOFAS) score and visual analogue scale (VAS) score were 48.75±3.46 and 6.08±1.14, respectively. ResultsThe mean operation time was 85.6 minutes (range, 65-125 minutes). Eleven patients were followed up for 19.4 months on average (range, 13-30 months). All of the cases obtained primary healing of incision, with no complication of infection and nerve or blood vessel injury. X-ray film showed that the mean time of bone union was 9.8 weeks (range, 7-18 weeks); no bone nonunion occurred. No loosening or breakage of internal fixation was observed. Pain occurred at the calcaneal-cuboid joint (1 case) and at fixation site (1 case), and was relieved after symptomatic treatment. The mean AOFAS score and VAS score were significantly increased to 81.36±2.98 and 0.72±0.11 respectively, showing significant differences when compared with preoperative scores (t=19.946, P=0.000; t=16.288, P=0.000). ConclusionSubtalar and talonavicular joints arthrodesis by a single medial incision approach is a useful alternative to tri ple arthrodesis for the correction of flatfoot deformity with pes valgus
