Two experimental patterns of autogenous nerve replantation in situ and centrocentralnerve suture were performed on the rabbit median and ulnar *** results of light andtransmission electron microscopy as well as immunohistochemistry showed that autogenous nervereplantation in situ could inhibit the formation of *** mechanism might be that twoproximal stump axons could touch within the interpolated graft *** end-to-endnerve suture failed to inhibit neuroma development because of a lack of proper environment forthe touching between two proximal stump axons.

Penile amputation and successful replantation is very uncommon, and there is no routine standardized procedures for dealing with this medical condition. Here we report two cases of penile amputation and replantation involving different degrees of vascular insult leading to different pathogenesis, clinical presentation, surgical approach and prognosis. This report described the microsurgical procedure and postoperative care using bipedicled scrotal flap to achieve successful engraftment and function. A review of the published data and future methods to increase success of such surgical procedures is provided.

Both severed legs were replanted in a 41-year-old man. Bilateral tibia and fibula were shortened by 4 cm equally. Tibial fixation was performed with reconstruction plate. Four weeks after the replantation, active and passive exercises were initiated in both of the knee joints. Four months after surgery, the patient was capable of walking independently for 20-30 m without the aid of crutches. After 28 months＇ follow-up, plantar sensitivity was defined as S3. This patient was satisfactory with the cosmetic and functional results.

In cases of severe segmental injury across the hand and wrist, but one or other fingers are still in peak condition, the fingers can be selected for replantation at the forearm bones to restore pinch function. Here we reported an unusual case with a severe crush-avulsion amputated injury to the right hand caused by a machine accident. We conducted hand reconstruction using heterotopic replantation of the amputated index and little *** 19 months follow-up, the bone union healed well with satisfactory outcome. The interphalangeal and metacarpophalangeal joint of the fingers after the heterotopic replantation had a good holding activity. This is a worthwhile procedure and the patient is satisfied with the result. The major disadvantage of this method is the poor appearance of the reconstructed fingers.

Radiographic changes consisting of al- terations in mineral content, osteopaenia or destructive neuropathy that occur following successful finger replantation have already been described. We report our experience about four fingers in three individuals in whom bone changes developed in the first three months postoperatively with complete ＂restitution ad integrum＂. Three patients, 21-49 years old （average 36 years） sustained a clean-cut amputation of four fingers. The first patient had an amputation at the base of the middle phalanx of the index finger and the second patient at the base of the proximal phalanx of the ring finger. The third had an amputation at the base of the first metacarpal bone and the proxi- mal phalanx of the small finger in a five finger amputation. In the first case, two dorsal veins and two palmar digital arteries and nerves were repaired. In the second case, one pal- mar artery and one dorsal vein were reanastomosed. In the third case at the thumb, two dorsal veins and two palmar digital arteries and nerves were reconstructed. At the small finger, one dorsal vein, one palmar digital artery and twodigital nerves were reconstructed. Bone fixation was achieved with two and three K-wires or tension-band wiring. replantation was successful in all cases. Three weeks after replantation, the X-rays showed rapid development of osteopaenia in the juxtaarticular region and metaphyses of the bone. These changes were followed by subperiosteal, intracortical and endosteal bone resorption. No further surgical procedures or splintage were needed and hand therapy was not discontinued. At 10-13 weeks （average 12 weeks） postoperatively, the X-rays showed a complete recovery with new periosteal bone formation. We suggest that the radiographic changes after finger replantation are transient, first evident subperiosteally and progressing centrally. They may reflect small-vessel compromise and microinfarction and transient hyperemia secondary to neurovascular da

Objective： To explore the measures and methods for improving distal phalanx replantation. Methods： One hundred and forty-eight cases with distal phalanx replantation from Sep 2004 to Sep 2007 were investigated. The indication for surgery and the operative program was determined by the trauma type and the degree of injury. As many microcirculation pathways as possible were reconstructed during the operation, and postoperative tissue decompression was also performed. Results： The survival rate of distal phalanx replantation was 89.9% （169/148）. Conclusion： To improve the survival rate of distal phalanx replantation it is essential to reconstruct an effective local blood circulation, determine the degree of injury in cases with ecchymosis, and employ comprehensive postoperative measures.

Abstract:Radiographic changes consisting of alterations in mineral content, osteopaenia or destructive neuropathy that occur following successful finger replantation have already been described. We report our experience about four fingers in three individuals in whom bone changes developed in the first three months postoperatively with complete "restitution ad integrum".Three patients, 21-49 years old (average 36 years) sustained a clean-cut amputation of four fingers. The first patient had an amputation at the base of the middle phalanx of the index finger and the second patient at the base of the proximal phalanx of the ring finger. The third had an amputation at the base of the first metacarpal bone and the proximal phalanx of the small finger in a five finger amputation. In the first case, two dorsal veins and two palmar digital arteries and nerves were repaired. In the second case, one palmar artery and one dorsal vein were reanastomosed. In the third case at the thumb, two dorsal veins and two palmar digital arteries and nerves were reconstructed. At the small finger, one dorsal vein, one palmar digital artery and two digital nerves were reconstructed. Bone fixation was achieved with two and three K-wires or tension-band wiring. replantation was successful in all cases.
