PURPOSE: The clinical decision to replant an amputated digit is driven primarily by surgical indication. However, the extent to which patient comorbidity should play into this decision is less well defined. This study was designed to determine the effect of patient comorbidities on the success, risk, and cost of digital replantation. METHODS: All amputation injuries and digital replantation procedures captured by the National Inpatient Sample during 2001 to 2012 were identified...

Open segmental fractures of both bones of the forearm with the loss of the middle segment of the radius is a rare injury in children. An eight-year-old boy presented to our clinic four days following a road traffic accident. The child's mother was carrying a 12-cm long extruded and soiled segment of the radius bone. The extruded bone segment seemed necrotic, and we decided not to use it for replantation. The wound over the forearm fracture was infected. It was debrided and regularly dressed until it became healthy...

The thumb plays an integral role in hand function. Traumatic amputation results in significant morbidity. With loss of the thumb, up to a 40% reduction in hand function may result. Thumb replantation must be attempted when possible. The goals of thumb reconstruction are to replicate normal function as closely as possible, minimize donor site morbidity, and expedite recovery. In the setting of a mutilated hand, the status of the remaining digits must be carefully assessed. Toe transfers, osteoplastic thumb reconstruction, and pollicization are commonly used...

BACKGROUND: Most microsurgeons believe that smoking and severity of injury adversely affect the outcome of digital replantation surgery. As countermeasures, several pharmacologic agents have been used for the perioperative period. The purpose of this retrospective study was to examine whether the rate of necrosis is appreciably different across smokers versus nonsmokers with prostaglandin E1 therapy. METHODS: The authors' study subjects included 144 patients (184 digits) who underwent replantation or revascularization between August of 2013 and August of 2015...

Rehmannia glutinosa is an important medicinal herb that cannot be replanted in the same field due to the effects of autotoxic substances. The effects of these substances on R. glutinosa in continuous cropping systems are unknown. In the present study, bioassays revealed that R. glutinosa exhibited severe growth restriction and higher disease indices in the FO+FA (F.oxysporum pretreated with ferulic acid) treatment. The increases in the contents of MDA and H2O2 were greater in the FA+FO treatment than in the FA or FO only treatments, respectively...

Many plant-pathogenic bacteria were dependent on quorum sensing (QS) to evoke disease. In this study, the population of QS and quorum quenching (QQ) bacteria was analyzed in consecutive monoculture system of Pseudostellaria heterophylla. The isolated QS strains were identified as Serratia marcescens with SwrIR-type QS system and exhibited a significant increase over the years of monoculture. Only one QQ strain was isolated from new planted soil sample and identified as Bacillus thuringiensis which secreted lactonase to degrade QS signal molecules...

Total scalp avulsion with severe cervical spine injury is a contraindication for emergency replantation of the scalp to its anatomical site. We describe a case involving the ectopic implantation of an avulsed scalp on the forearm. A 41-year-old woman presented with severe total scalp avulsion and tears in the intervertebral discs at the C4/5 and C5/6 levels. The avulsed scalp was ectopically implanted on the left forearm with a tissue expander to provide support. Two-stage replantation of the scalp at its anatomical site was performed 19 and 40 days later...

BACKGROUND: Tooth replantation after traumatic avulsion or transplantation is a challenge in oral surgery. A special method named auto-alloplastic replantation, in which a titanium post is used after extraoral endodontic treatment, combines several advantages. The treatment is performed in one step with no further endodontic intervention, no wide root canal instrumentation, no recontamination, and reduced endodontic infection. This is the first report on replantation of an ectopic tooth in a patient with a cleft lip and alveolus using this method...

The thumb is the most important part of the hand. If thumb is amputated, all efforts should be made to replant it to preserve hand functions. Good functional outcome can be obtained with successful thumb replantation than with other reconstructive surgery. We present a case of thumb amputation of a 44 -year-old male with severe damage to the soft tissues and bony structures of the radial part of the hand. We performed the replantation anastomosing the superficial palmar branch of the radial artery as donor artery as the proximal part of thumb digital arteries were severely damaged due to crush injury and got favorable result...
