We performed hand-assisted laparoscopic surgery for a 67-year-old male with a 5.6 cm sized abdominal aortic aneurysm. To the best of our knowledge, this is the first report in Korea. After an initial hand dissection of the abdominal aorta under laparoscopy, we performed proximal anastomosis and distal abdominal. aorta suture ligation through a 6 cm abdominal incision. Distal anastomosis was done at the bilateral common femoral arteries. He resumed his oral intake 6 hours after the surgery and discharged at the $4^{th}$ postoperative day.

Introduction: The hand and wrist are particularly susceptible to electrical burn. Skin defect with damage or exposure of underlying vital structure requires coverage by skin flap especially in case of the need for late reconstruction. We are reporting 4 cases of electrical burned hand treated by posterior tibial arterial free flap. The commonly used skin flaps such as scapular flap or groin flap are too bulky so that they are not satisfactory in function and cosmetic appearance. So we tried to cover them with a more thin skin flap. Materials and Method: From January 2002 to June 2003, four cases of hand and wrist electrical burn were covered using posterior tibial arterial free flap. All the cases were due to high voltage electrical burn. Age ranged from 31 years to 38 years old and all the cases were male patients. Recipient sites were 2 wrist, one thenar area and one knuckle of 2.3rd MP joint. Additional procedures were flexor tenolysis (simultaneous), FPL tenolysis and digital nerve graft (later) and extensor tendon reconstruction (later). Result: All the flap have survived totally without any complication including circulatory concern about the donar foot. Posterior tibail arterial free flap was so thin that debulking procedure was not required. Conclusion: For skin coverage of the hand & wrist region, posterior tibial arterial free flap have many advantages such as reliable anatomy, easy dissection and easy anastmosis with radial or ulnar artery and possibility of sensory flap. The most helpful advantage for hand coverage is its thinness. So we think this flap is one of the very useful armamentarium for reconstructive hand surgery.

Skeletal metastasis are common in terminal malignant tumor patients over 30% of incidence, but hand acrometastasis are very rare under 0.1% in terminal cancer patients. We have reported 5 cases of hand acrometastasis herewith the review of literatures. In the preterminal malignant tumor patients, sudden painful swelling on fingers and osteoporosis on X-rays are thought to be the earliest sign of hand metastasis.

Dupuytren's contracture is a condition commonly encountered by hand surgeons, although it is rare in the Asian population. Various surgical procedures for Dupuytren's contracture have been reported, and the outcomes vary according to the treatment modalities. We report the treatment results of segmental fasciectomies with multiple transverse incisions for patients with Dupuytren's contracture. The cases of seven patients who underwent multiple segmental fasciectomies with multiple transverse incisions for Dupuytren's contracture from 2006 to 2011 were reviewed retrospectively. Multiple transverse incisions to the severe contracture sites were performed initially, and additional incisions to the metacarpophalangeal (MCP) joints, and the proximal interphalangeal (PIP) joints were performed if necessary. Segmental fasciectomies by removing the fibromatous nodules or cords between the incision lines were performed and the wound margins were approximated. The mean range of motion of the involved MCP joints and PIP joints was fully recovered. During the follow-up periods, there was no evidence of recurrence or progression of disease. Multiple transverse incisions for Dupuytren's contracture are technically challenging, and require a high skill level of hand surgeons. However, we achieved excellent correction of contractures with no associated complications. Therefore, segmental fasciectomies with multiple transverse incisions can be a good treatment option for Dupuytren's contracture.

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.

When the scrotal sac is entirely debrided following a Fournier gangrene, testes exposure poses unique challenges for the reconstructive surgeon. Despite the anterolateral thigh (ALT) flap is considered a workhorse in such context, aesthetic results are often suboptimal because of the lack of natural ptosis and patchwork appearance. We describe the use of a super-thin pedicled ALT flap for total scrotal reconstruction, modified according to a peculiar flap design and inset technique. A 42-year-old man was referred to our department for delayed total scrotal reconstruction 8 months after a Fournier gangrene extensive debridement. A super-thin pedicled ALT flap from the right thigh was designed: in the central portion of the ALT, a lateral skin paddle extension was marked to guarantee adequate posterior anchorage during insetting and ptosis of the scrotal sac. This particular flap arrangement has inspired the name "sombrero" as the shape is akin to the famous hat. No secondary refinements were needed, and the patient showed satisfying aesthetic and functional results at 12 months' follow-up. The ALT flap design "sombrero" modification proposed in this article can improve scrotum cosmesis and patient satisfaction in a single-stage single-flap procedure.

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.

The anterior interosseous artery (AIA) perforator flap is not commonly used in hand dorsum reconstruction compared with alternatives. However, it is a versatile flap with several advantages. Literature on the AIA perforator flap is based on the dorsal septocutaneous branch (DSB), which branches from the AIA and passes through fascia between the extensor pollicis longus (EPL) and extensor pollicis brevis muscles. In the described case, the authors reconstructed a hand dorsum defect in a 78-year-old man using an AIA perforator flap with double perforators supplied by the DSB and a new perforator branching from the distal than DSB. No complication was encountered, and the flap survived completely. A retrospective computed tomography review revealed the presence of the new perforator in 14 of 21 patients. Two types of new perforator were observed. One passed through the ulnar side of the extensor indicis proprius (EIP) muscle and penetrated fascia between the extensor digitorum minimi and extensor digitorum communis tendons, whereas the other passed between the EPL and EIP muscles. This report describes the anatomical location and clinical application of the new AIA perforators. The double perforators-based AIA flap provides a straightforward, reliable means of reconstructing hand dorsum defects.

The authors analyzed the clinical results of the reconstructive surgery for injuried hand with microsurgery in 33 patients, 35 cases at the department of orthopaedic surgery, school of medicine, Kyung Hee university from 1985 to 1992 and the results were as followings. 1. There were 31 men and 4 women who had a mean age of 23 years(range, 3 to 44 years) and the follow up evaluations averaged 19 months. 2. The causes of the injury were machinery injury in 25 cases, traffic accident in 2, frostbite in 4, burn in 3 and fall down in 1. 3. For the reconstructive procedure, scapular free flap was applied in 6 cases, radial forearm flap in 7, dorsalis pedis free flap in 4, neurovascular island flap in 6, gracilis free flap in 1, wrap around flap in 6, toe to thumb in 5. 4. 32 cases(91.4%)were successful in reconstructive surgery with microsurgery exept the failure of scapular free flap in 2 cases and dorsalis pedis free flap in 1. 5. The causes of failure in scapular free flap were infection in 1 case and thrombosis in 1. In dorsalis pedis free flap, the cause of failure was infection. In the analysis of above results, the reconstruction with microsurgery was effective procedure for reconstruction of injuried hand.

Although breast implants have been in clinical use for almost 6 decades and have undergone considerable development during this time, implant rupture is still a dreaded long-term complication. Some obvious external factors, such as trauma, can lead to implant rupture, but many studies have reported a high rate of "spontaneous" implant rupture. Herein, we present two cases with the aim of raising awareness of a new possible cause of "spontaneous" implant rupture: mechanical irritation by bony protrusions.
