A review of suture anchors

Suture anchors are designed to allow soft tissue to bone healing in cases where inadequate soft tissue stock on bone makes it impossible to perform a direct soft tissue-to-soft tissue repair. Suture anchor fixation is one of the most important innovations in arthroscopic glenohumeral shoulder surgery, optimizing the link between bone and soft tissue at the rotator cuff footprint. Newer developments and techniques have expanded the use of suture anchors to most other musculoskeletal tissues including the hip, elbow, hand, knee foot and ankle.Their success depends on having an understanding of the biology and biomechanics that affect their use and knowing the factors that may affect the clinical outcome. This review concentrates on the design, insertion technique, composition and evolution of suture anchors in orthopaedic surgery and the ways in which they are utilised in different tissues.

Concealed cosmetic closure in total knee replacement surgery – A prospective audit assessing appearance and patient satisfaction

ObjectiveWith the trend towards accelerated rehabilitation, the method of skin closure has become increasingly important in orthopedic surgery. It is imperative to evaluate a technique that provides superior clinical and cosmetic results specifically for TKA, due to relatively thin skin anterior to the knee making poor wound healing an issue of concern. We conducted a prospective, single-arm audit evaluating the patient assessments of incision cosmesis for a novel technique in TKA wound closure called Concealed Cosmetic Closure (CCC).Methods570 knees were included in the study whose wound was closed with concealed cosmetic subcuticular interrupted sutures (CCCIS) between January 2014 and May 2016. A validated, ordinal questionnaire, Stony Brooks Scar Evaluation Scale (SBSES) designed to elicit a score evaluating scar satisfaction was interviewed by the investigators to patients 6 months to 3 years postoperatively.ResultsCCC is a simple and relatively rapid single-operator technique that takes about 7–10 min to close 11–17 cm knee incision. In our study, the mean score for Stony Brook Scar Evaluation Scale (SBSES) was 4.4 (SD of 0.73) (range 3–5). The scar was rated highly in terms of cosmesis, patient satisfaction and appearance of the wound.ConclusionCCC is an effective modality for skin closure in total knee arthroplasty providing superior cosmetic healing with minimal complications leading to improved long term patient satisfaction.     

胆道手术缝合技术与缝合材料选择中国专家共识（2018版）

正胆道缝合重建是肝胆胰外科手术的最基本操作之一,建立胆汁引流通畅、无张力、血供充足的黏膜对黏膜吻合是胆道重建的基本要求。目前,胆道重建方式繁多,但根据所须重建胆道的病理生理状况选择合适的胆道缝合方法及缝合材料是保障胆道重建成功的关键因素。随着手术技术的进步及各种缝合材料的发展,胆道缝合技术越来越精细,高质量的胆道缝合重建是病人顺利康复及减少多次手术的关键。基于此,中华医学会外科学分会组织国内部分专家结合最新文献及胆道外科的最新进     

Barbed suture in gastro-intestinal surgery: A review with a meta-analysis

BackgroundThe laparoscopic approach is a very popular technique for many gastrointestinal operations and barbed sutures may improve the difficulties of intracorporeal anastomosis by eliminating the need for knot tying. The aim of this systematic review with a meta-analysis is to explore literature to establish the security profile of barbed suture compared with conventional laparoscopic sutures.Materials and methodsA systematic search was performed in all electronic databases (PubMed, Web of Science, Scopus, EMBASE) and 12 studies were included in the analysis, involving 27,133 patients, whereof 3372 cases (patients undergone barbed suture usage) and 23,761 controls (patients undergone conventional suture usage). We found 3 studies discussing differences between barbed and conventional sutures in colorectal surgery and 8 studies presenting results in bariatric surgery, both in Roux-en-y gastric bypass and Mini Gastric/One Anastomosis Gastric Bypass.ResultsWe found comparable rate of leaks, bleedings and stenosis. The meta-regression analysis demonstrated that, both in case of bariatric and colorectal surgery, the demographic characteristic of patients and the oncological features of neoplasms did not impact of these findings. As expected, operative time is significantly shorter when barbed suture is used.ConclusionOur analysis on current literature define an acceptable security profile for barbed suture with effective results particularly in terms of shorter operative time.

A comparison of double single suture-button fixation,suture-button fixation,and screw fixation for ankle syndesmosis injury: A retrospective cohort study

Different methods have been used throughout the years for syndesmotic injury but there is no consensus on the ideal treatment. Some methods are expensive and some have more complications. The aim of this study is to compare single suture endobutton with double suture endobutton and screw fixation for syndesmotic injury.Sixty nine patients with syndesmotic injury with fibular fractures whom were treated with a single interosseous suture endobutton system (ZipTight^TM, Zimmer Biomet), a double interosseous suture endobutton system (ZipTight^TM, Zimmer Biomet) and 1 syndesmotic screw (TST, Istanbul, Turkey) were included in this study. Functional and radiological results from patient records between 2015 and 2018 were retrospectively evaluated.Twenty patients were treated with the double interosseous suture endobutton, 23 were treated with the single interosseous suture endobutton, and 26 were treated with traditional AO screw fixation. Three patients from the screw fixation group (11.5%) required revision surgery (P < .05). All the radiologic and clinical outcomes were statistical similar in all 3 groups.Our findings showed that the interosseous suture endobutton system is at least as safe as the screw fixation technique for treatment of syndesmosis joint injuries and can be used as an alternative to the screw method. The interosseous suture endobutton system eliminates the need for a second surgery to remove the hardware, which minimizes the probability of re-diastasis. Since our results showed no statistical difference between single and double interosseous suture endobutton systems, the less costly single endobutton system may be the better alternative.
