Despite the overall satisfactory results of total hip arthroplasty, post-operative complications continue to occur. To minimize these problems, computer-assisted total hip arthroplasty using navigation or robot-assisted systems is being developed. A navigation system is defined as a system that locates a position in three-dimensional space and traces the target spot, and a robot-assisted system is defined as a system that performs operations automatically with mechanical robot arms based on prior preoperative planning. Computer-assisted surgeries have shown superior results to conventional methods in implant positioning, fixation, and accurate lower extremity alignment in the limited reports available. However, computer-assisted surgeries take longer compared to conventional methods. Due to the extra time needed, the risk of postoperative infection and blood loss is considered to be higher. Nevertheless, robot-assisted system is being developed for the field of hip arthroplasty, and thus its efficacy and accuracy needs to be further investigated. Since these methods have other advantages compared to conventional methods, they are the focus of much interest.

Triceps rupture is the least common among all tendon injuries. The usual mechanism of injury is a fall on an outstretched hand, although direct contact injuries have also been reported to cause this injury. The diagnosis of acute triceps tendon rupture may be missed, which can result in prolonged disability and delayed operative management. We presented three cases of acute triceps tendon rupture each at different site showing the spectrum of injury to the muscle and mechanism of injury and management were also discussed.

OBJECTIVETo apply the scapular free flap extended to the upper arm for resurfacing the face and neck, as well as the upper lip in one stage.

METHODSThe scapular free flap was designed with extended portion to the posterior and interior part of the upper arm. Then the free flap was transferred to resurface the face and neck with the routine portion and to resurface the upper lip with the extended portion.

RESULTS6 cases with extensive upper lip, facial and cervical burn scar were treated with the extended scapular free flaps. The flap size ranged from 22 cm x 11 cm to 40 cm x 9.5 cm (36.57 cm x 10.20 cm in average) for the routine portion and from 7 cm x 4 cm to 12 cm x 4 cm (10.32 cm x 3.67 cm in average) for the extended portion. All flaps survived completely.

CONCLUSIONSThere are direct communicating branches ("choke vessel") between the circumflex scapular artery (CSA) and the posterior humeral circumflex artery (PHCA). When the blood supply of PHCA is cut off, the CSA can provide blood supply through the communicating branches to the upper arm skin area previously nourished by PHCA. So the blood supply of the extended portion of the scapular free flap is not only from the branches of CSA, but also from the direct communicating branches between the CSA and PHCA. The extended scapular free flap has a reliable blood supply and can be applied to construct the facial and cervical scar contraction with the extended portion to resurface the upper lip. The satisfactory result can be expected.

Scapulothoracic dissociation is a rare and complex injury pattern with varied presentation. Here we describe a case of a 32-year-old male who presented with scapulothoracic dissociation associated with brachial plexus injury, along with scapholunate dissociation. We also propose an injury mechanism that might link the two injury patterns, suggesting that the association might be more than by chance. The patient was managed according to established trauma care and resuscitation protocols followed by open reduction and internal fixation of the clavicle fracture, and fixation of scapholunate dissociation and had a successful outcome at follow-up.

OBJECTIVETo investigate the blood supply of the expanded skin flap from medial upper arm and its application on the reparation of facial defect due to scar resection.

METHODSThe operation was carried out for three steps: 1) The expander was embed under the superior proper fascia. 2) The skin flap from medial upper arm was created with superior ulnar collateral artery as blood supply and attributive branches of basilic and axillary veins as blood collection and was grafted onto the facial defect. 3). After being separated from donor site, the skin flap was employed to cover the facial defect with maximal area of 15 x 10 cm(2).

RESULTSSeven patients in all with facial scar and defects were managed with the skin flap. All the grafted skin flaps survived at last with nearly normal skin color, texture and contour. And the scar in donor sites seemed to be neglectable.

CONCLUSIONReparation of facial defects with medial upper arm skin flap after expanding could be recommended. But longer treatment time and some obsessive action of upper limbs and head might be disadvantages.

da Vinci(TM) Surgical System is an advanced mode of minimal invasive surgery, using 3-dimensional imaging system and robotic arms which can mimic the dexterity of the human hand. Thus, various operations can be performed with minimal incision and limited surgical field and the merits of minimal invasive surgery can be maximized by using it. We report our first experience of robotic open heart surgery using the da Vinci(TM) Surgical System for repairing atrial septal defect.

Fibrous hamartoma of infancy is an uncommon benign fibrous proliferation, usually presenting as a solitary nodule. A rare example of multiple fibrous hamartoma of infancy is described. Two masses which developed in the upper arm of a 10-month-old boy were successfully excised, and one month later three small nodules 2 cm below the previous operation field appeared. It will be further elucidated whether multiple forms and early recurrence are related or not as cases accumulate.

OBJECTIVETo improve a better method to achieve the upper arm's circumferential harmony by using adjacent aesthetic unit combined upper arm liposuction.

METHODSLiposuction of upper arm, axilla and part of the scapula area was performed on 88 cases at one stage from January 2007 to March 2013.

RESULTSAll the cases achieve satisfactory results. The circumferential curve is smooth and elegant. No severe complication happened.

CONCLUSIONSThis method proved to be safe and effective and can be accomplished in one stage.

arm flap (LUAF) was initially described by in 1982 by Song et al. as a simple skin flap, addressing the availability of cutaneous nerves for anastomoses. Katsaros et al., reported the use of a lateral upper arm skin flap, but also considered using it as a composite graft. The LUAF for the oral and maxillofacial reconstruction has several advantages over other flaps, such as constant anatomy, good color match and texture, thin design and plasticity. There is no functional limitation in the donor arm, such as strength and extension, and donor defects can be closed primarily with a linear scar, even when a flap of up to 8 cm in width is taken. For a better understanding of LUAF as a routine reconstructive option in moderate defect of maxillofacial region, the constant anatomical findings must be learned and memorized by young doctors during the specialized training course for the Korean national board of oral and maxillofacial surgery. This article review the anatomical basis of LUAF with Korean language.]]>

OBJECTIVETo evaluate the result of subdermal vascular network skin flap raised from the upper arm to interchange with a facial skin flap carrying a scar resulted from previous burn.

METHODSA transit flap was designed in the anterior medial aspect of the upper arm according to the reverse design method. The subdermal vascular network flap in the upper arm with length-width ratio less than 1.5:1 was raised with the pedicle located outside of the intermuscular septum of musculus biceps/triceps brachialis. The length-width ratio of the facial scar flap should be less than 1.2:1. The two flaps were cross-grafted to repair the facial wound left by raising the scar flap. The pedicles of the flaps were divided on 14 approximately 15 post-operative days (PODs).

RESULTSThe two flaps survived with satisfactory appearance in 9 patients with this method.

CONCLUSIONInterchange of facial scar flap with subdermal vascular network skin flap from the upper arms could be a new, reliable and effective method for the facial plastic surgery.
