Objective To present some revision surgery for correcting short and bulky outward appearance of reconstructed finger pulp in toe-to-hand transfer. Methods Since Sep. 1998 to Dec. 2006,in a series of 33 patients, 39 fingers had been reconstructed with 2nd toe. In order to change the shape of bulbous distal toe segment into a normal tapering fingertip, revisional operations had been designed, i.e. (1)Excision of bulky skin and excessive soft tissue from one or both sides of the finger pulp. (2)Transfer and inlaid the excised lateral soft tissue flap to the central constricting part of the finger pulp. (3)Full thickness skin graft to palmar central narrow part of toe pulp. 4. Rotational transfer of local lateral "L" shape flap. Results All the patients healed by first intention with no skin necrosis occurred. The bulbous rectangular shaped toe pulp were corrected and outward appearance were much improved in most cases. Though the outward appearance in one simple skin graft case was not satisfactory in correcting flexion deformity of distal segment and increased its circumference. Conclusion In toe-to-hand transfer, the distal segment of reconstructed finger often shown to have an bulbous toe pulp appearance, which may bring psychological burden to the patient and their relatives. Simple revisional surgery recommended here may yield favorable improvement.

Objective To discuss the clinical application and therapeutic effect of repairing deformed thumb in the way of transposition of abandoned polydactyly with neurovascular bundles.Methods From January 2005 to December 2011,six cases of type Ⅳ deformities of thumb duplications were treated with excision of thin and deformed thumb phalangette of trunk,the redundant hyperdactylia,which was well-formed and involved in the first web space,was then transposed with neurovascular bundles to the thumb phalangette of trunk by the first web space and the side of thumb for fixation followed by repairation of form of thumb phalangette.The surplus metacarpal bone and phalanx of duplications were removed and the first web space was reconstructed.Results All 6 cases of heterotopic thumb phalangette transplanted to the deformed thumb phalangette were completely survived.Kirschner wires were removed 4 weeks after operation.Fracture healing occured after 4 to 6 weeks after operation.Postoperative follow-up period ranged from 3 months to 1 year.Transplanted thumbs possessed well-formed appearance with previous sensation on the finger pulp as well as excellent function of grabbing and opposing.Conclusion To repair deformity of trunk thumb in the way of microsurgery by means of transposition of duplicated thumb with neurovascular bundle which should be abandoned,is a simple operation with satisfactory and reliable postoperative effect.It shall be spred and applied.

Objective To assess and review the methods of the reversed posterior interosseous artery flap for treating the contracture of the first web space. Methods Forty-two cases of the first web space severe contracture were cured by the reversed posterior interosseous artery flap rotate at 1.5-2.0 cm proximal ulnar styloid process after release the adhesion. After operation curative effects were evaluated by measuring the first web space with Gu's method. Results The flap of 42 cases obtain success, however 3 cases was partly necrosis of epidermis. Follow-up examination was obtained in 31 cases for average 18 months after operative.The width of the first web space was augmented an average of 37.9 mm. Rehabilitation training after operation can enhance the effect of the therapy with 8.6 mm more expanded. Conclusion The flap is an ideal choice for treatment on the defect of the contracture of the first web space and rehabilitation training after operation is important.

Objective To explore the concept,denomination and technique of miniature tissue transplantation in hand clinic. Methods In 537 cases,local skin or composite tissue defect in 756 thumbs or fingers were repaired with 4 kinds of miniature island flap and 10 kinds of miniature vascularized composite tissue.Some of them were created in clinic practice.The precess,main points and indication of the operation were expounded and compared. Results In 639 fingers covered with miniature island flap,the transferred flaps were surviverd completely in 621 fingers(97.2%),survivered partly in 11 fingers(1.7%)and necrosised in 7 fingers(1%).In 117 fingers repaired with miniature vascularized composite tissue,all the transplanted tissues were survivered.In all the injuried fingers,beautiful outlook were recovered and no fat and clumsy were found,two-point difference was 6-8 mm,effctive sensibility and good function were restored,and all the patients were satisfied. Conclusion Miniature tissue transplantation were good methods to cover the local defect in fingers or thumbs,worth of generalization and aplication in hand clinic,and have an important significance for improve the trauma repair quality and treatment level in hand surgery.
