Urbaniak class III ring avulsion injuries involve significant soft tissue and bone loss. Management typically focuses on immediate, temporary soft tissue coverage followed by a planned trip to the operating room for either amputation or replantation. While soft tissue coverage is of utmost importance, maintenance of digital length, functionality, and cost-effectiveness of viable treatment options should also be considered. Read More

The etiology of surface and inflammatory root resorption after the replantation of incisors was examined in green vervet monkeys. The teeth were examined histologically and histobacteriologically for pulpal healing and root resorption 2 and 8 weeks after replantation. In contrast to surface resorption, inflammatory resorption was related to infected necrotic tissue or an infected leukocyte zone in the root canal. Read More

Central ray amputation results severe esthetic blemish and functional and psychological sequelae. Three main reconstruction procedures have been reported in adults: digital translocation, intracarpal osteotomy, and metacarpal resection; none of these, however, have been studied in children. The aim of this study was to report medium-term results for treatment of central ray amputation by proximal metacarpal resection following failure of digit replantation in children (i. Read More

Most nail bed injuries occur along with other fingertip injuries; however, isolated total avulsion injuries of the nail bed are uncommon. To obtain optimal results, reconstructive methods should be selected judiciously depending on the type of injury, the patient's needs for their economic status and postoperative aesthetics, and postoperative morbidities. Replantation with an avulsed nail bed, if feasible, can be a reasonable treatment option to avoid the morbidities of other donor sites. Read More

Purpose: Dental injuries (DIs) are associated with facial fractures, particularly mandibular fractures. As paediatric mandibular fractures have special features, we sought to clarify the occurrence and types of DIs among this patient group. We assessed how age, injury type, and fracture location affects the occurrence of DIs and thereby defined which patients are most susceptible. Read More

Since microsurgical finger replantations started to be successfully performed at the beginning of the 1960 s, there has been an evolution in the techniques for restoring blood flow to the amputated fingers. Initially, end-to-end anastomoses were performed. Later on, vascular grafts - predominantly vein interpositional grafts - were successfully used for difficult avulsion injuries. Read More

A massive quantity of (oil palm) trunk biomass, containing a significant amount of natural starch, is available in Malaysia as bio-waste because of annual replantation. The efficient extraction of this starch (carbohydrate polymer) would be worthwhile concerning the environmental sustainability and economy through conversion to bio-resources. This study investigated the effectiveness of the bisulphite steeping method for starch synthesis from oil palm trunk (OPT) bio-waste. Read More

The management of mangled upper extremity is very challenging because the anatomical complexity of the region, the large number of possible involved anatomical elements, and the necessity of obtaining a good functionality. The impressive development of microsurgical techniques in the last decades contributed a lot to the salvage of several extreme injuries with mangled extremities considered untreatable in the past. Such injuries can nowadays be successfully managed by means of replantation/revascularization or complex reconstruction by using simple or complex microsurgical flaps. Read More

Although there have been numerous reports of major replantation of upper extremity amputations, limited numbers of above-elbow amputation replantation have been reported. We present the technical details of two successful replantations of forequarter amputations in a nine-year-old girl and a three-year-old boy. In both cases, the forequarter was amputated due to avulsion traction injuries resulting in amputation including the entire upper limb, while the integrity of the scapula and parascapular muscles was maintained, with no injury to the glenohumeral joint.

Background/aim: Root length is a critical factor for dental pulp regeneration following tooth replantation. The aim of this study was to analyze the effects of reducing the root length by apicoectomy on the pulp healing process using a model for tooth replantation.

Material And Methods: After extraction of the upper first molars (M1) of 3-week-old mice, the roots from the experimental group (EG) were shortened to half to two-thirds of their length before replantation, whereas in the control group (CG) the extracted teeth were immediately repositioned into their alveolar sockets.

At the Summit on Organ Banking through Converging Technologies held recently in Boston, tissue and organ cryopreservation technology was a topic of considerable interest. Although cryopreservation has been widely used in clinical practice, it currently remains limited to bloodless tissues with simple structures and functions that are small or thin, for example, ultra-thin skin, ovarian tissue slices, and other similar tissues. For whole organs, except for successful cryopreservation of rat ovaries (2002) and hind limbs (August 2002), successful cryopreservation of vascularized animal tissues or organs and their replantation have not yet been reported.

Replantation of digital amputations is now the accepted standard of care. However, rarely will a replantation surgeon be presented with amputated fingers which have been previously replanted. In our literature search, we could find only one publication where a replanted thumb suffered amputation and was successfully replanted again. Read More

Random-pattern skin flap replantation is generally used in the reconstruction of surgical tissues and covering a series of skin flap defects. However, ischemia often occurs at the flap distal parts, which lead to flap necrosis. Previous studies have shown that andrographolide (Andro) protects against ischemic cardiovascular diseases, but little is known about the effect of Andro on flap viability. Read More

Introduction: reduced exercise capacity, coronary artery abnormalities and reversible myocardial ischemia have been demonstrated after arterial switch operation (ASO) and coronary reimplantation. Despite this, indices of systolic function, assessed by standard and Doppler echocardiography, are within the normal range. The aim of this study was to highlight the long-term changes in myocardial function following coronary reimplantation using Doppler and speckle-tracking imaging (STI) echocardiography. Read More

The purpose of this retrospective study was to compare the outcomes of paediatric and adult fingertip replantation within a single institution. Our retrospective study found no significant difference in the survival rate between the paediatric (10/12) and adult (22/26) groups. At 6 months follow-up, there was no significant difference in sensory recovery between both groups, as measured with Semmes-Weinstein testing, but a significant difference in mean static two-point discrimination testing values between the paediatric (4.

Tooth transplantation is one of the treatment options for extracted teeth that can be considered before dental implantation. Although the success rate of tooth transplantation is lower than that of implantation, tooth replantation and transplantation have the great advantage of using natural teeth. Tooth replantation might be considered a promising option in some cases. Read More

A hemi-pulp flap is widely known as a flap useful for aesthetic and functional reconstruction of the fingers, and rarely used for toe reconstruction. We performed third toe pulp reconstruction using a free hemi-pulp flap harvested from the contralateral second toe to repair the tissue defect following toe replantation. An 18-year-old woman was injured with complete left third toe amputation and open fracture of the proximal phalanx of the left second toe in a traffic accident. Read More

Supermicrosurgery is defined as microsurgery working on vessels less than 0.8 mm, allowing applications in smaller-dimension microsurgery, such as lymphedema, minimal invasive reconstruction, small parts replantation, and application of perforator as recipient. To accommodate this technique, developments and use of finer instruments, smaller sutures, new diagnostic tools, and higher-magnification microscopes have been made. Read More
