Objective: The acquisition of surgical skills requires motor learning. A special form of this is intermanual transfer by transferring motor skills from the nondominant hand (NDH) to the dominant hand (DH). The purpose of this study was to determine the learning gains that can be achieved for the DH by training with the DH, the NDH, and by non-surgical alternative training (AT).Methods: 124 preclinical (n=62) and clinical (n=62) dental students completed surgical knot tying and suturing technique training with the DH, with the NDH, and an AT in a controlled randomized trial. Results: A statistically significant learning gain in knot tying and suture technique with the DH was evident only after training with the DH when compared to training with the NDH (p

Substantial nerve lesions almost always lead to persistent functional deficits, even with ideal treatment. Nerve lesions commonly occur in young patients, are often part of complex injuries, and are repeatedly diagnosed and treated with delay. Functional outcome crucially depends on early and adequate treatment. The aim of surgical treatment is a precise and tension-free microsurgical restoration of nerve continuity in a vital and healthy tissue environment. Adequate microsurgical treatment with differentiated postoperative treatment can result in an excellent clinical outcome, even after a delayed diagnosis., Competing Interests: Einhaltung ethischer Richtlinien.

In accordance with the guidelines suture procedures, a preperitoneal mesh technique, the laparoscopic intraperitoneal onlay mesh (IPOM) or the new minimally invasive techniques, i.e. the endoscopic mini/less open sublay (E/MILOS) technique, enhanced-view totally extraperitoneal (eTEP) repair and totally endoscopic sublay (TES) repair should be used for primary abdominal wall hernias (umbilical hernia, epigastric hernia) depending on the defect size and patient characteristics (obesity, rectus abdominis muscle diastasis). For incisional hernias the sublay operation and laparoscopic IPOM continue to be the techniques most commonly used, whereby laparoscopic IPOM is being increasingly replaced by the open sublay operation and the new techniques (E/MILOS, eTEP and TES). For defects greater than 10 cm posterior component separation with transversus abdominis muscle release is becoming increasingly more established. There are also abdominal wall hernias (recurrences, lateral and combined lateral and medial defects) necessitating an open IPOM or an onlay technique. [ABSTRACT FROM AUTHOR]

Adhesions and scar formation between flexor tendons and the surrounding tissue can currently only be prevented by mobilization oft he flexor tendon. Active treatment concepts are more favorable than passive mobilization. The main risks of flexor tendon repair are rupture of the tendon suture, gradually progressive dehiscence and inhibition of tendon gliding within the tendon sheath. Currently, there is no consensus with respect to the optimal suture technique and suture material. Nevertheless, there are some noteworthy principles, such as the use of suture material with a greater diameter, locked suture techniques, sutures with four or more strands as well as simple circular running sutures. A technically acceptable compromise, even for persons with less practice, is currently a 4-thread suture in combination with a circular running suture, which guarantees sufficient stability for active postoperative treatment without causing resistance.

The extensor tendon apparatus is a network consisting of two different systems, an intrinsic and an extrinsic system, which are subdivided into eight different zones. Isolated injuries in zones 1 and 2 can be treated nonoperatively, whereas injuries in zones 3–8 usually require surgical treatment. A decision on the suture technique, suture material and postoperative follow-up care is made depending on the zone of the injury. The concomitant injuries of joints, bones, nerves and vessels must be taken into consideration and treated. The outcome of a tendon injury depends on the location and severity of the injury as well as the surgical technique and follow-up care. Exact knowledge of the anatomy with precise diagnostics, atraumatic, zone-dependent surgical and postoperative treatment, adequate rehabilitation and occupational therapy are essential for high quality management and preservation of fine motor skills and coordination of the whole hand.

Ziel der chirurgischen Versorgung von Beugesehnenverletzungen ist die frühzeitige Wiederherstellung der Kontinuität durch eine ausreichend stabile Naht, um eine frühfunktionelle passive oder aktive Behandlung zu erlauben und so Adhäsionen der Sehne - insbesondere im osteofibrösen Kanal der Finger - zu vermeiden. In den letzten Jahren wurde eine Vielzahl an Nahttechniken in den unterschiedlichsten Modifikationen beschrieben. Im Sinne „je mehr Nahtmaterial, desto stabiler“ wurde der Fokus auf die Erhöhung der Stranganzahl der Kernnaht gelegt, um frühzeitig aktive Nachbehandlungskonzepte zu erlauben. Trotz der höheren initialen biomechanischen Stabilität dieser Nahttechniken in experimentellen Studien konnte in klinischen Übersichtsarbeiten hinsichtlich der Rupturrate kein statistisch signifikanter Unterschied zwischen Zweistrang- und Mehrstrangnähten nachgewiesen werden. Auch bezüglich des funktionellen Ergebnisses war keine Überlegenheit der Mehrstrangtechniken gegenüber den Zweistrangtechniken nachzuweisen. Dementsprechend gibt es bis heute, abgesehen von einer stabilen Kernnaht und einer glättenden Feinadaptation, keinen Goldstandard hinsichtlich der idealen Nahttechnik oder des optimalen Nahtmaterials zur Versorgung von Beugesehnenverletzungen.

The treatment of flexor tendon injuries remains a challenge for all involved; therefore, good anatomical knowledge, a precise operative procedure and excellent postoperative physiotherapeutic and ergotherapeutic care are important to achieve a good functional result. Up to now no consensus has been reached or a high level of evidence achieved concerning the suture technique and suture material. Nevertheless, a 4-strand core suture with a circular running suture represents a good compromise. This achieves a sufficiently stable situation to be able to initiate early functionally active mobility to prevent adhesion between the tendon and the surrounding soft tissues.

The 1-year incisional hernia rate of 9-30 % has been tolerated for decades. Even in the 1970s and 1980s there was evidence that supported reducing suture tension. Recently, the traditional 4:1 relationship between suture and wound length, which has been passed on for years, has been questioned. After first experimental and clinical data suggested an advantage by reducing the width and interval of stitches by 50 %, the prospective randomized STITCH study has now provided evidence by significantly lowering the 1-year hernia rate from 21 % to 13 %. For surgeons this means less of a revolution and more of an innovative evolution of a long-established technique. Before introduction of the technique quality assurance must be carried out with documentation of performance indicators (e.g. number of stitches, length of thread incorporated and wound length).

Exact knowledge of the topographical anatomy of the arterial vascular system is the basis for all access routes. This article describes the most important assess routes in the neck and torso regions and gives an overview of the basic principles of the surgical technique with respect to suture material, suture technique, anastomotic technique and the atraumatic preparation of the anastomosis region. The article makes no claims to completeness because this would overstretch the limits but refers in particular to the references listed. [ABSTRACT FROM AUTHOR]

Although minimally invasive approaches to the abdominal cavity are becoming increasingly more important, open surgical techniques are still of essential interest and must be mastered by general and visceral surgeons. The choice of the particular approach depends on the specificity and location of the scheduled procedure. The following article is intended to give an overview on the current literature as well as experiences in the field of open surgical approaches to the abdominal cavity. [ABSTRACT FROM AUTHOR]
