  • Thigh perforator flaps are used popularly, because they have a small thickness, a long vascular pedicle and a low rate of donor site morbidity. Among thigh perforator flaps, anterolateral thigh perforator flaps are generally used, but it is not easy to dissect the vastus lateralis muscle to find the vasuclar pedicle. The authors have planed 11 anteromedial thigh perforator flaps that have septocutaneous perforators. We were able to find anteromedial thigh perforators in 8 cases(72.7%). The perforators originated from the medial descending branch of the lateral circumflex femoral artery in 2 cases and a branch to the rectus femoris muscle in 6 cases. Of this type of surgery, 7 flaps survived. However, 1 flap failed because of arterial insufficiency. We believe the anteromedial thigh perforator flap is a good option when the thigh region is decided as a donor site, but surgeons should keep in mind that the perforator of anteromedial thigh flap may be absent.

  • Mobile computing devices (MCDs), such as smartphones and tablets, are revolutionizing medical practice. These devices are almost universally available and offer a multitude of capabilities, including online features, streaming capabilities, high-quality cameras, and numerous applications. Within the surgical field, MCDs are increasingly being used for simulations. Microsurgery is an expanding field of surgery that presents unique challenges to both trainees and trainers. Simulation-based training and assessment in microsurgery currently play an integral role in the preparation of trainee surgeons in a safe and informative environment. MCDs address these challenges in a novel way by providing valuable adjuncts to microsurgical training, assessment, and clinical practice through low-cost, effective, and widely accessible solutions. Herein, we present a review of the capabilities, accessibility, and relevance of MCDs for technical skills acquisition, training, and clinical microsurgery practice, and consider the possibility of their wider use in the future of microsurgical training and education.

  • Vascularized bone grafts (VBGs) are widely employed to reconstruct upper extremity bone defects. Conventional bone grafting is generally used to treat defects smaller than 5-6 cm, when tissue vascularization is adequate and there is no infection risk. Vascularized fibular grafts (VFGs) are mainly used in the humerus, radius or ulna in cases of persistent non-union where traditional bone grafting has failed or for bone defects larger than 6 cm. Furthermore, VFGs are considered to be the standard treatment for large bone defects located in the radius, ulna and humerus and enable the reconstruction of soft-tissue loss, as VFGs can be harvested as osteocutaneous flaps. VBGs enable one-stage surgical reconstruction and are highly infection-resistant because of their autonomous vascularization. A vascularized medial femoral condyle (VFMC) free flap can be used to treat small defects and non-unions in the upper extremity. Relative contraindications to these procedures are diabetes, immunosuppression, chronic infections, alcohol, tobacco, drug abuse and obesity. The aim of our study was to illustrate the use of VFGs to treat large post-traumatic bone defects and osteomyelitis located in the upper extremity. Moreover, the use of VFMC autografts is presented.

  • The conventional approach of looking down a microscope to perform microsurgical procedures is associated with occupational injuries, anti-ergonomic postures, and increased tremor and fatigue, all of which predispose microsurgeons to early retirement. Recently, three-dimensional (3D) visualization of real-time microscope magnification has been developed as an alternative. Despite its commercial availability, no supermicrosurgical procedures have been reported using this technology to date. Lymphovenous anastomoses (LVAs) often require suturing vessels with diameters of 0.2-0.8 mm, thus representing the ultimate microsurgical challenge. After performing the first documented LVA procedure using 3D-augmented visualization in our unit and gaining experience with this technique, we conducted an anonymized in-house survey among microsurgeons who had used this approach. The participants considered that 3D visualization for supermicrosurgery was equivalent in terms of handling, optical detail, depth resolution, and safety to conventional binocular magnification. This survey revealed that team communication, resident education, and ergonomics were superior using 3D digital hybrid visualization. Postoperative muscle fatigue, tremor, and pain were also reduced. The major drawbacks of the 3D visualization microscopic systems are the associated costs, required space, and difficulty of visualizing the lymphatic contrast used.

  • Various soft tissue defects can be occurred in the hand. In determining the most suitable means of reconstruction a defect, the benefit of the reconstruction has to outweigh the risk of donor morbidity. Flap selection will be based on the size of the defect, the requirements for sensibility, the surgeon's comfort level, and the patient profile such as gender, age, or systemic disease. The hand is the most important tactile sensory organ, hence sensory restoration is critical. Neurosensory free flaps can provide sensibility, vascularity, and soft tissue coverage to an injured hand. This paper will discuss free flaps which can be used for soft tissue reconstruction of the hand.

  • Avulsion of the triceps brachii is an uncommon injury. The usual mechanism of injury is fall onto an outstretched hand but can occur after direct contact injuries. Diagnosis is critical and dependent on history, physical examination, and radiological findings. Rupture of triceps brachii occurs most frequently at the tendo-osseous insertion and may be complete or partial, and could be associated with radial head fracture. Treatments include surgical repair of the complete rupture and immobilization of partial triceps rupture. We report 3 cases of triceps avulsion fractures treated by open surgical repair with literature reviews.

  • Robotically assisted microsurgery or telemicrosurgery is a new technique using robotic telemanipulators. This allows for the addition of optical magnification (which defines conventional microsurgery) to robotic instrument arms to allow the microsurgeon to perform complex microsurgical procedures. There are several possible applications for this platform in various microsurgical disciplines. Since 2009, basic skills training courses have been organized by the Robotic Assisted Microsurgical and Endoscopic Society. These basic courses are performed on training models in five levels of increasing complexity. This paper reviews the current state of the art in robotically asisted microsurgical training.

  • Blazed up Herpes zoster lesions have been described in very few patients after free and pedicled flap transfer for reconstructive purpose. Although sensory recovery after flap reconstructions has been studied extensively most studies addressed subjective perceptions of sensation. Objective investigations of spontaneous reinervation of free and pedicled flaps are rare. We would like to present a witnessed herpes zoster infection of a latissimus dorsi skin flap 2 years after breast reconstruction.

  • We experienced a case of 49-year-old male patient with amputated two fingers preserved in Soju (Korean traditional liquor, a kind of alcoholic beverages). The amputation level of the two fingers was at the distal interphalangeal joint. The Soju was not an adequate physiologic solution for preserving the amputated tissues. Even though arterial anastomosis was successful, there was no venous drainage visible in the operative field. On the first day after the initial operation, we succeeded in the anastomosis of one vein in one of the two amputated fingers. This was 12 hours after arterial anastomosis was carried out. But no venous dranage was visible in the other finger. In spite of a salvage procedure sustained with external bleeding for 7 days, this replanted fingertip eventually fell into necrosis.
