ABSTRACT
Objective To study the short-term and medium-term effects of mini- strip anchor and capsulotomy in the treatment of first metacarpophalangeal joint dislocation in rheumatoid arthritis (RA). Methods From January 2015 to December 2016,fifty-eight RA patients with first metacarpophalangeal joint dislocation were randomly divided into study group (20 cases),joint replacement group (19 cases) and non-operation group (19 cases). Postoperative evaluation indexes: the wound healing was observed in accordance with ＂trial standard of functional evaluation of upper limbs of Chinese Medical Association Hand Surgery Society＂. The surgical outcomes of the three groups were compared. The hand function and quality of life were assessed by Michiga Hand Outcomes Questionnaire ( MHQ ) and arthritis impact measurement scale 2 (AIMS2) before treatment, 6 months after treatment and 12 months after treatment. Results All the patients in the study group and the joint replacement group healed by first intention without any early complications. According to the criteria of upper extremity functional evaluation of Chinese Medical Association,the curative effect of the operation was evaluated. In the study group,15 cases were excellent,3 cases were good,2 cases were poor,the excellent and good rate was 90. 0%. In the joint replacement group, 15 cases were excellent,3 cases were good,1 case was poor,and the excellent and good rate was 94. 7%. After treatment for 6months, the MHQ scores were improved significantly in the three groups (( 48. 36 ±8. 24) vs. (73. 06±10. 55); (47. 56±7. 75) vs. (81. 42±8. 54); (48. 75±8. 85) vs. (65. 91±8. 26)) (F＝33. 19,35. 12,28. 42, P＜0. 05). The MHQ scores of study group ( (73. 06±10. 55)points) and joint replacement group ( ( 81. 42 ± 8. 54) points) were significantly higher than those of non-operation group ((65. 91± 8. 26) points) ( P＜0. 05), and the MHQ scores of joint replacement group were significantly higher than those of study group (P＜0. 05). At 12 months after treatment,there was no significant difference in MHQ score between the study group ((82. 45±7. 18)points) and the arthroplasty group ((84. 36±6. 33) points) (P＞0. 05) . At 6 and 12 months after treatment, AIMS2 scores of each group were significantly improved,but AIMS2 scores of study group (( 216. 51 ± 35. 28) points, ( 230. 28 ± 23. 51) points) and arthroplasty group ((221. 45±31. 63) points,(234. 15±21. 42) points) were significantly higher than those of non-operation group ((192.69±41.31) points,(200.43 ±28.42) points) (P＜0.05).At 6 and 12 months after treatment,there was no significant difference in AIMS2 scores between the study group and the arthroplasty group ( P ＞ 0. 05 ) . Conclusion Micro-strip line anchors combined with posterior capsulorrhaphy in the treatment of first metacarpophalangeal joint dislocation in rheumatoid arthritis can achieve good stability of articular reduction,significantly improve the joint function and quality of life and have ideal short-term and mid-term effect.
ABSTRACT
To evaluate the efficacy of Tuina and Chinese patent drug Shuxuetong injection in preventing patients undergoing total knee arthroplasty from deep venous thrombosis and in functional rehabilitation.
ABSTRACT
Objective To evaluate the outcome of primary total knee arthroplasty (TKA) in treatment of stiff knee, and discuss the key points of operative technique and rehabilitation. Methods From February 2005 to April 2009, 23 patients with 34 stiff knees were treated with primary TKA. The study included 3 males (4 knees) and 20 females (30 knees), with the mean age of 56.9 years. Primary disease of the patients included rheumatoid arthritis (26 knees in 15 cases) and osteoarthritis (8 knees in 8 cases). Varus deformity was found in 10 knees (5°-15°), and valgus was found in 5 knees (5°-10°). Evaluations included preoperative and postoperative range of motion (ROM) measurement, hospital for special surgery knee score (HSS), blood loss, operative time and assessment of postoperative complications. Results All patients were followed up. The mean follow-up time was 32.2 (range, 24 to 40) months. At the final follow-up visit, the HSS score increased from 42.9±5.2 preoperatively to 85.7±4.3, the range of motion increased from 42.6°±5.7° preoperatively to 89.2°±10.5°. Sixteen knees in 12 cases underwent manipulation at 3 to 8 weeks postoperatively for unsatisfied ROM, but ROM was still less than 90° in 8 knees at the last follow-up. The average blood loss were (632.4±180.2) ml in first 24 hours (450-850 ml) and the operative time were (98.1±18.6) min (80-150 min). Deep venous thrombosis was found in 3 patients. All the symptoms relieved after anticoagulant therapy. Postoperative varus deformity was seen in one patient, but the function of knee was good. No revision was needed. Conclusion Primary total knee arthroplasty is reliable method in treatment of stiff knees. Sufficient soft tissue release during the operation, postoperative muscle strength exercise and essential manipulation are key points for satisfactory outcomes.
ABSTRACT
Objective To compare the effect of glucosamine (Virtral-s) on the cartilage oligomeric matrix protein (COMP) secretion of chondrocytes and synoviocytes in vitro.Methods Chondrocytes and synoviocytes isolated from knee cartilage of osteoarthritic patients were cultured by phased enzymatic digestion.Sera containing Virtral-s of the experimental animals were obtained after orally administrated Virtral-s at the dosages that equal to human.Cells were cultured in the medium with Virtral-s containing sera.Super-natant COMP level was tested by enzyme-linked immunoabsorbent assays (ELISA).Results COMP conceu-tration of synoviocytes cultured in vitro was significantly higher than that of chondrocytes (P＜0.05).Virtral-s could significantly increase COMP secretion in cultured chondrocytes in vitro (P＜0.05),however,it had a weaker role on synoviocytes,ie,it could only mildly reduce COMP secretion of synoviocytes.Conclusion Glucosamine (Virtral-s)-containing serum can promote COMP secretion of chondrocytes in vitro,and it has no significant effect on synoviocytes in vitro.
