Anatomical and clinical study on partial pectoralis minor transplantation for reconstruction of the opposition of the thumb / 中华显微外科杂志

Objective To investigate a new surgical method by using pectoralis minor muscle for its partial transplantation to reconstruct the function of the opposite thumb anastomosed vessels and nerves. Methods The proposed method was evaluated by taking 20 cases of adult cadaveric thoraxes and hands,then compared with the morphology and dimension of both pectoralis minor muscle and palmer muscle to study the feasibility of the new method.Based on the observed data.We selected five suitable cases,in which the opposi- tion function was lost,and then applied the new operation on them with partial transplantation of pectoralis mi- nor muscle anastomosed vessels and nerves according to the results of anatomic study.The follow-up study was conducted to observe the functional recovery of opposition of the thumb.Results The main results can be summarized as follows.First,the anatomical position of pectoralis minor muscle was stable,and every peetoralis minor muscle was provided with self-sustaining artery,vein and nerve.The oppostition process of cadaveric hand succeeded after similar transplantation to clinic operation.Second,follow-up studies conducted 6 - 12 months after the operation showed that all five patients recovered fully.The muscle strength in all five cases re- covered to level four or higher.The shape of palm eminence was satisfactory.Conclusion The surgical method of pectoralis minor muscle transplantation for reconstructing the opposition function of the thumb was based on the clinical and anatomical application.The function of opposition of the thumb reached the satisfacto- ry requirement after the operation.So,the new surgical method can achieve better results than other existing operation methods.

Treatment of diabetic foot with microsurgical operation / 中华显微外科杂志

Objective To report clinical study of diabetic foot with microsurgical treatment.Methods 32 cases basing on physical treatment underwent operation which included reconstruction of vessel under DSA and flap transfer and relaxation of nerves.Results 8 eases were examined with DSA after operation,it showed that the bypass grafts were unobstructed and the distal blood were improved;All flap were lively. Conclusion The ulcer of the patients with diabetic foot was closed early and the blood supply of the limb have been reconstructed by microsurgical treatment,it can not only avoid amputation or lower the limb amputation level,but also improve the life quality of patients and obtain social benefit.
