We present a case of a successful bilateral leg replantation in a 3-month-old baby after a knee-level crush amputation with the loss of both knee joints. The legs were replanted after 4 hours of warm and an additional 2.5 and 3.5 hours of cold ischemia time. Both legs show motor and sensory reinnervation, without additional procedures performed on the right leg, and after a nerve reconstruction with cadaveric allografts on the left leg. Both replanted legs exhibit excellent bony and soft tissue growth. Two years after the injury, the patient is progressing well with rehabilitation, with favourable odds of having knee reconstructions performed at a later age...

PURPOSE: The recommended surgical treatment after thumb amputation is replantation. In the United States, fewer than 40% of thumb amputation injuries are replanted, and little is known about factors associated with the probability of replantation. We aimed to investigate recent trends and examine patient and hospital characteristics that are associated with increased probability of attempted thumb replantation. We hypothesized that higher-volume teaching hospitals and level-I trauma centers attempted more replantations...

Inverted tooth impaction is a rare occurrence. Third molar impaction is the most extensively studied, and only eight cases of inverted third molars have been reported in a literature search of 40 years from 1973 to 2013. In a study, 43.4% of the premaxillary supernumeraries were inverted and 21.1% were transversely oriented, while occasional inverted central incisors have been mentioned in the literature. Severe dilaceration makes the management of this case a big challenge. The case of an 8-year-old boy with an inverted, rotated, and impacted upper left central incisor obstructed by an odontome is presented here...

Background: The success of tissue transplantation and long-term tissue stability after wound healing depends on sufficient tissue perfusion. Laser Doppler-supported procedures allow for an objective measurement of relative tissue perfusion. The development of Speckle-based Laser Doppler imaging now enables a real-time representation of tissue perfusion. The perfusion of tissues relevant in plastic surgery such as scars, phalangeal replantations and burn wounds were systematically analysed by Laser Speckle Contrast Analysis (LASCA) imaging...

PURPOSE: We sought to determine and quantify which subspecialties of orthopedic surgeons are operating off hours in an urban, quaternary-care, level 1 trauma center. MATERIALS AND METHODS: We used our clinical registry to identify 43,211 orthopedic surgeries performed between January 2008 and December 2011. Our outcome measures were the number and proportion of off-hour surgeries performed as well as the number and proportion of off-hours per subspecialty. The denominators were the total number of surgeries and the total number of surgical hours worked per subspecialty...

BACKGROUND: After major upper extremity traumatic amputation, replantation is attempted based upon the assumption that outcomes for a replanted limb exceed those for revision amputation with prosthetic rehabilitation. While some reports have examined functional differences between these patients, it is increasingly apparent that patient perceptions are also critical determinants of success. Currently, little patient-reported outcomes data exists to support surgical decision-making in the setting of major upper extremity traumatic amputation...

PURPOSE: Hospital volume-outcome association has been examined for many high-risk surgical procedures. Little is known about this association for thumb replantation, a complex but essential surgical procedure to restore hand function. We aimed to determine patient and hospital characteristics that are associated with increased probability of replanted thumb survival and to examine volume-outcome association among hospitals that performed thumb replantation. METHODS: We used data from 2008 to 2012 from the National Trauma Data Bank...

Total scalp avulsion is a rare but severe injury frequently ending in hair loss, and one that can even be life-threatening. It frequently occurs in women and in men with long hair and as a result of injuries by industrial or agricultural equipment or of animal attacks. The first option in treatment is replantation of hairy skin with microsurgery.The authors report 2 consecutive patients with total scalp avulsion presenting to our clinic. Similar injury mechanisms and total scalp avulsions were present in both patients...

Tissue-engineered vascular grafts that are based on reconstituted extracellular matrices have been plagued by weak mechanical strength that prevents handling or anastomosis to native vessels. In this study, we devise a method for making dense, suturable collagen tubular constructs of diameter ≤1 mm for potential microsurgical applications, by dehydrating tubes of native rat tail type I collagen and crosslinking them with 20 mM genipin. Crosslinked dense collagen tubes with 1 mm inner diameter yielded ultimate tensile strength of 342 ± 15 gF and burst pressure of 1313 ± 156 mm Hg, comparable to the strength of a rat femoral artery, and supported endothelial cell adhesion and growth...

BACKGROUND: Fingertip amputation in children is difficult to manage using microsurgical replantation techniques and many salvage procedures have failed owing to the nonavailability of suitable veins for anastomosis in the fingertip. This study reviewed our experience of pediatric fingertip replantation involving palmar venous anastomoses and evaluated the clinical outcomes. METHODS: From October 2008 to May 2013, 21 pediatric fingertips that had been completely amputated at or distal to the distal interphalangeal joint of the finger, or at or distal to the interphalangeal joint of the thumb were managed using complete replantation...

Tooth replantation success depends on the condition of cementum periodontal ligament after tooth avulsion; which is influenced by storage medium. The dragon's blood (Croton lechleri) sap has been suggested as a promising medium because it supports collagen formation and exhibits healing, anti-inflammatory and antimicrobial properties. Thus, the aim of this study was to evaluate the efficacy of dragon's blood sap as a storage medium for avulsed teeth through evaluation of functional and metabolic cell viability...

BACKGROUND/AIM: Replantation of avulsed teeth may lead to root resorption. Bisphosphonates (BPs), a class of drugs of used to treat resorptive diseases of the bone such as osteoporosis and Paget's disease, have been observed to exert an anti-resorptive effect on periodontal bone as well. The anti-resorptive properties of BPs could prove them useful in preventing root resorption of replanted avulsed teeth. The aim of this systematic review was to analyze and summarise the currently available literature concerning the use of BPs in preventing root resorption of avulsed teeth...

BACKGROUND/AIM: The viability of periodontal ligament (PDL) cells is a significant determinant of the long-term prognosis of replanted avulsed teeth. A storage medium is often required to maintain the viability of these cells during the extra-alveolar period. Many studies have been carried out to search for the most suitable storage medium for avulsed teeth, but an ideal solution has not yet been found. The purpose of the study was to compare and analyze the ability of coconut milk and probiotic milk to maintain PDL cell viability...

INTRODUCTION: The goal of replantation after dental avulsion is to maintain the tooth in its socket. Presence of vital periodontal ligament cells on the root surface of the replanted tooth and the immunologic status of the patient are factors that protect against root resorption. It is known that dental constituents play an active role in root resorption by inducing specific and non-specific immune responses; however, little information exists regarding the influence of the acquired immune response on replantation...

Background The surgical microscope is still essential for microsurgery, but several alternatives that show promising results are currently under development, such as endoscopes and laparoscopes with video systems; however, as yet, these have only been used for arterial anastomoses. The aim of this study was to evaluate the use of a low-cost video-assisted magnification system in replantation of the hindlimbs of rats. Methods Thirty Wistar rats were randomly divided into two matched groups according to the magnification system used: the microscope group, with hindlimb replantation performed under a microscope with an image magnification of 40× and the video group, with the procedures performed under a video system composed of a high-definition camcorder, macrolenses, a 42-in television, and a digital HDMI cable...

Ilyonectria mors-panacis belongs to I. radicicola-species complex and causes root rot and replant failure of ginseng in Asia and North America. The aims of this work were to identify I. mors-panacis that infect Korean ginseng using molecular approaches and to investigate whether their aggressiveness depends on their ability to metabolize ginseng saponins (ginsenosides) by their β-glucosidases, in comparison with other identified Ilyonectria species. Fourteen isolates were collected from culture collections or directly isolated from infected roots and mainly identified based on histone H3 (HIS H3) sequence...
