踝关节镜下修复距腓前韧带治疗慢性踝关节不稳

目的探讨踝关节镜下改良Brostr?m法解剖修复距腓前韧带(ATFL)治疗慢性踝关节不稳的临床疗效。 方法选取2015年12月至2017年1月慢性踝关节不稳患者共12例,均采用踝关节镜辅助下改良Brostr?m法解剖修复距腓前韧带进行治疗。采用美国足踝外科学会(AOFAS)评分标准、Tegner运动水平评分及距骨倾斜角变化对手术前后疗效进行评价,随访观察并发症发生情况。治疗前后各观察指标比较采用配对t检验。 结果12例均获得15～46个月随访,平均(26±8)个月。随访期间,所有患者踝关节活动度基本达到正常水平,未出现踝关节不稳,无踝关节肿胀、疼痛等表现,末次随访AOFAS评分为(91.0±2.6)分、Tegner评分为(6.0±1.2)分,两者较术前均明显提高(t ＝10.57、12.38,均为P<0.001)。距骨倾斜角(4.5±1.0)°较术前降低(t＝7.13,P<0.001)。 结论踝关节镜下改良Brostr?m法解剖重建ATFL治疗慢性踝关节不稳,能更精准地探查韧带断端、定位韧带附着点、创伤小、疼痛轻、术后恢复快,疗效理想。     

关节镜下四袢与双袢固定修复急性肩锁关节Rockwood V型脱位疗效对比研究

目的对比评估双骨道四袢与单骨道双袢固定修复急性肩锁关节Rockwood Ⅴ型脱位疗效。 方法回顾性分析2010年5月至2016年5月于深圳大学第一附属医院接受关节镜下双骨道四袢与单骨道双袢固定修复急性肩锁关节Rockwood Ⅴ型脱位的所有患者,其中入选82例手术患者,四袢双骨道组与双袢单骨道组各41例。术后2年内随访观察患者的视觉模拟评分（visual analogue scale,VAS） 、患者恢复运动时间、恢复运动患者数量、Constant功能评分、Karlsson肩锁关节功能评分,并通过影像学观察评估喙锁关节和肩锁关节的间隙。 结果术后2年内末次随访X线片显示四袢双骨道组患侧平均喙锁关节和肩锁关节的间隙与双袢单骨道组对比明显减小,且差异具有统计学意义（P<0.05）;双袢单骨道组患者健侧平均喙锁关节和肩锁关节的间隙与患侧对比明显减小,且差异具有统计学意义（P<0.05）;然而四袢双骨道组患者健侧平均喙锁关节和肩锁关节的间隙与患侧对比差异无统计学意义（P>0.05）。两组患者术后末次随访患肢疼痛均有明显减轻,术前与术后VAS评分对比差异具有统计学意义,两组组间对比差异无统计学意义。四袢双骨道组重返运动的时间较双袢单骨道组明显缩短,重返患者数目明显多于双袢单骨道组,且Constant功能评分、Karlsson肩锁关节功能评分均明显优于双袢单骨道组,差异均具有统计学意义（P<0.05）。四袢双骨道组并发症明显少于双袢单骨道组。 结论采用关节镜下双骨道四袢固定治疗Rockwood V型脱位,方法固定可靠,并发症少,较双袢单骨道固定效果更佳,是治疗急性肩锁关节Rockwood V型脱位损伤较好的方法。     

Distraction arthroplasty in osteoarthritis of the foot and ankle

Post-traumatic osteoarthritis(PTOA) is a complex and painful problem in the foot and ankle.Ninety percent of osteoarthritis cases in the foot and ankle can be classified as post-traumatic.PTOA can affect any of the 33 joints in the foot and the ankle.Distraction arthroplasty is a method for treatment of early arthritic joints without fusing or replacing them and its effectiveness has been well documented.The purpose of this case series is to present our successful experiences and positive results using distraction arthroplasty to treat PTOA in the ankle,subtalar,first metatarsophalangeal,and second tarsometatarsal joints,and to present distraction arthroplasty as a viable alternative to invasive joint sacrificing procedures such as arthrodesis or arthroplasty.Distraction Arthroplasty effectively and safely treats PTOA and improves the stability of joints in the Foot and Ankle.Additionally,the use of bone marrow aspirate concentrate as an adjuvant can improve the long-term functional and structural outcomes of the joint,and can prolong the need for further,more aggressive surgical interventions such as fusion or arthroplasty.     

Conversion to reverse shoulder arthroplasty fifty-one years after shoulder arthrodesis: A case report

BACKGROUND Patients with a shoulder arthrodesis generally experience restriction in range of motion and limitations in activities of daily living. In addition, up to one-third of the patients deals with serious peri scapular pain. The conversion of a shoulder arthrodesis in a reverse shoulder arthroplasty(RSA) has been described as an effective treatment to achieve better function and decreased pain, although literature is sparse. We present the case of a conversion from a painful shoulder arthrodesis to RSA, after a 51 years interval.CASE SUMMARY A 71-year-old male presented with severe peri scapular pain and limited function 51 years after shoulder arthrodesis. Preoperative workup showed a normal bone stock of the glenoid and an intact axillary nerve, but atrophic posterior part of the deltoid muscle. The shoulder arthrodesis was successfully converted to RSA. Twelve months postoperative the patient was very satisfied. He has no pain at rest, nor with exercise and experienced definite improvements in activities of daily living, despite his limited range of motion.CONCLUSION Conversion from shoulder arthrodesis to a RSA can be performed safely, with a high chance of peri scapular pain relief; even after a longstanding arthrodesis.
