PURPOSE: Implantation of a reverse total shoulder arthroplasty (rTSA) places the axillary and suprascapular nerves at risk. The aim of this anatomic study was to digitally analyse the location of these nerves in relation to bony landmarks in order to predict their path and thereby help to reduce the risk of neurological complications during the procedure. METHODS: A total of 22 human cadaveric shoulder specimens were used in this study. The axillary and suprascapular nerves were dissected, and radiopaque threads were sutured onto the nerves without mobilizing the nerves from their native paths...

A technique for posterior meniscal root reinsertion is presented. With the arthroscope in the central transtendinous portal for a better view, a 5-mm transtibial tunnel is created with the aid of an anterior cruciate ligament guide open to 45°. A suture device, which consists of a long needle with an eyelet on its tip, is introduced through the tunnel with a suture thread inserted through the eyelet, while the meniscus is stabilized with a grasper inserted through the anterior portal. The meniscus is pierced with the device, and the suture thread is recovered with said grasper...

In the present retrospective analysis, we introduce a custom suture-button fixation device for acute ankle syndesmotic injuries that allows for early weightbearing without another planned operation for hardware removal. We evaluated 87 consecutive ankles in 87 patients (49 males [56.32%] and 38 females [43.68%]). Of the 87 patients, 15 (17.24%) withdrew or were lost to follow-up, leaving 72 patients (82.76%) in the present study. Their mean age was 35.2 (range 17 to 67) years. Nineteen patients (26.39%) presented with a pure syndesmotic disruption, and 53 (73...

BACKGROUND: Uniportal video-assisted thoracoscopic surgery (VATS) is an alternative modality for treatment of primary spontaneous pneumothorax (PSP) with its less invasiveness and acceptable surgical outcomes. However, a few reports have been introduced for wound management to achieve better cosmetic wound healing and for placement of the chest tube in uniportal VATS. Thus, we aimed to evaluate the feasibility of our novel method for wound closure and concomitant tube placement using continuous barbed suture material in uniportal VATS for PSP...

Suture threads of cotton or linen, in crossed and random orientation, were added to alginate-chitosan membranes intended to wound coatings application to improve the mechanical properties. The elongation at break increased to about 5 and 8 times for membranes with linen and cotton, respectively, both in the crossed orientation. The addition of the threads increased roughness and opacity of the membranes and reduced the liquid absorption capacity and water vapor transmission rate. The lowest toxicity to human fibroblasts was observed for extracts of membranes produced with linen, and incorporation in them of epidermal growth factor was able to slightly increase cell proliferation...

BACKGROUND: Eversion carotid endarterectomy (ECEA) is an effective surgical technique for the treatment of internal carotid artery (ICA) stenosis. However, a residual distal intimal flap may determine a higher rate of neurological complications. The treatment of DIF may be challenging, and no definitive approach has been described. We describe a simple surgical option for the treatment of DIF. METHODS: After internal ECEA has been performed, stitches are positioned at the side of intimal flap...

BACKGROUND: With the evolution of facial rejuvenation methods, thread lifts have gained popularity among patients who seek cosmetic improvement. Absorbable wedge-shaped polydioxanone (PDO) sutures are currently available, and they are extremely popular in the aesthetic clinics in Korea. In case of midface and mandibular jowl lift, threads are most often inserted in an oblique manner with vectors of rejuvenation directed toward the temple. However, specific characteristics of skeletal anatomy should be considered when deciding which technique to use in Asians...

BACKGROUND: In recent years, the type of surgical treatment for Achilles tendon rupture has been the subject of controversial debate. This biomechanical study evaluates for the first time in literature the ultimate failure load (UFL) of interlocking horizontal mattress (IHM) suture as compared with Kakiuchi suture in Achilles tendon rupture. The hypothesis is that IHM suture can be performed also for Achilles tendon rupture and ensures higher resistance compared with the traditional Kakiuchi suture...

BACKGROUND: Uterine rupture is a potential life-threatening complication during a trial of labor after cesarean delivery. Single-layer closure of the uterus at cesarean delivery has been associated with an increased risk of uterine rupture compared with double-layer closure. Lower uterine segment thickness measurement by ultrasound has been used to evaluate the quality of the uterine scar after cesarean delivery and is associated with the risk of uterine rupture. OBJECTIVE: To estimate the impact of previous uterine closure on lower uterine segment thickness...

We report in this paper the effects of Ethyl Ester L-Lysine Triisocyanate (LTI) on the physical-mechanical properties of Poly(lactide)/Poly(ε-caprolactone) (PLA/PCL) polyesters blends. The PLA/PCL ratios considered were 20/80, 50/50 and 80/20 (wt/wt %) and LTI was added in amounts of 0.0-0.5-1.0 phr. PLA and PCL reacted with LTI during processing in a Brabender twin screw internal mixer to produce block copolymers in-situ. The resulting blends have been characterized by torque measurements, uniaxial tensile tests, Differential Scanning Calorimeter, contact angle measurements with a Phosphate Buffered Saline (PBS) solution, ATR analysis and morphological SEM observations...

We propose a technique to repair delamination, which often occurs during rotator cuff repair surgery. We have reported that the infraspinatus occupies most of the greater tuberosity with the articular capsule attached to a very wide area, and that the superficial layer is mainly composed of the infraspinatus, and the deep layer is mainly composed of the articular capsule. To repair such delamination with consideration of the detailed anatomy, we developed the following repair method with independent repair of the superficial layer (infraspinatus) and the deep layer (articular capsule): (1) the deep layer is pulled laterally and joined to the medial margin of the greater tuberosity using 4 simple sutures from 2 anchors; (2) the paired limbs (same color) of 4 knots are passed over the posterior leaf of the superficial layer at intervals; (3) a push-in anchor loaded with 1 thread each of 4 knots is placed on the anterolateral corner of the greater tuberosity to pull the superficial layer anterolaterally; (4) another push-in anchor (remaining threads) is pushed on the posterior corner of the greater tuberosity...
