  • CLINICAL COMPARATIVE STUDIES ON MULTIPHASE LIPECTOMY AND ONEPHASE LIPECTOMY WITH SKIN GRAFT TRANSPLANTATION IN SKIN FLAP CONTOURING

    To discuss the advantages of two flap contouring methods and to explore the best choice for the flap contouring. Methods From March 2002 to March 2006, 59 patients were admitted for a flapcontouring operation. Of the 59 patients, 40 (32 males, 8 females; average age, 34 years) underwent the multiphase lipectomy (the multiphase lipectomy group). The original flaps included the abdominal flap in 19 patients, the groin flap in 10, the thoracic flap in 4, the free anteriolateral thigh flap in 6, and the cross leg flap in 1. The flaps ranged in size from 6cm×4 cm to 32 cm×17 cm. However, the remaining 19 patients (16 males, 3 females; average age, 28 years) underwent the onephase lipectomy with skin graft transplantation(the onephase lipectomy group). The original flaps included the abdominal flap in 4 patients, the groin flap in 6, the thoracic flap in 3, and the free anteriolateral thighflap in 6. The flaps ranged in size from 4 cm×3 cm to 17 cm×8 cm. The resultswere analyzed and compared. Results In the multiphase lipectomy group, partial flap necrosis developed in 4 patients but the other flaps survived. The followedup of 27 patients for 3 months to 2 years revealed that the flaps had a good appearance and texture, having no adhesion with the deep tissues. However, the flaps became fattened in 22 patients with their body weight gaining. The patietns who had a flap gt; 5 cm×5 cm in area had their sensation functions recovering more slowly; only part of the sensations to pain and heat recovered. The two point discrimination did not recover. In the onephase lipectomy group, total graft necrosis developed in 1 patient but the healing was achieved with additional skin graft transplantation; partial graft necrosis developed in 2patients but the wounds were healed after the dressing changes; the remaining flaps survived completely. The followup of the 16 patients for 3 months to 3 years revealed that all the 16 patients had a good sensation recovery, 12 patientshad the two point discrimination lt; 15 mm, with no recurrence of the fattening of the flaps; however, the grafted skin had a more severe pigmentation, and no sliding movement developed between the skin and the tissue basement. Conclusion The multiphase lipectomy and the onephase lipectomy with skin graft transplantation are two skin flap contouring methods, which have their ownadvantages and disadvantages. Which method is taken should be based on the repair location of the 〖WT5”BZ〗skin flap and the condition of the skin flap.

  • REPAIR OF SOFT TISSUE DEFECTS OF WRIST AND FINGERS BY ANTEGRADE AND RETROGRADE DORSAL METACARPAL FLAPS WITH CUTANEOUS BRANCHES AS PEDICLES

    Objective To investigate the procedure and applications ofantegrade and retrograde dorsal metacarpal flaps with cutaneous branches as pedicles in repairing soft tissue defects of wrist and fingers. Methods From 1995 to 2003, we observed that the proximal and distal branches, deriving from the dorsal metacarpal artery, formed a consistent anastomosis arc subdermally. The anastomosis arc was paralleled to the dorsal metacarpal artery. Antegrade and retrograde dorsal metacarpal flaps could be designed using proximal anddistal branches as pedicles. Twenty-seven cases of soft tissue defects were treated by use of dorsal metacarpal flaps with cutaneous branches as pedicles, including 3 cases of defects on dorsum of hand with antegrade flaps, and 24 cases of defects on fingers with retrograde flaps ( index finger:12 cases; middle finger: 6 cases; ring finger: 4 cases; and little finger:2 cases). The dimensions of the antegrade flaps were 2.0 cm×4.0 cm~4.0 cm×6.0 cm, and the dimensions of theretrograde flaps were 2.5 cm×3.5 cm~3.0 cm×7.0 cm.The incision of the donor site was closed directly. Results All flaps survived. After a follow-up of 13 years, the texture and color of the flaps were good, and the shape and function of the donors were normal. Conclusion The antegrade or retrograde flap pedicled with the distal or proximal cutaneous branches of thedorsal metacarpal artery, is an optimal flap in repairing finger or wrist softtissue defects.

  • 插秧致中环指伸肌腱自发性断裂修复后早期疗效

    【摘 要】 目的 总结肌腱移植修复插秧致中、环指伸肌腱自发性断裂的早期疗效。 方法 2006 年4 月- 2009年4 月,采用肌腱移植修复21 例(28 指)插秧后发生中、环指伸肌腱自发性断裂。男5 例,女16 例;年龄35 ~ 44 岁,平均42 岁。均因单侧中指和(或)环指不能伸直2 ~ 19 d 就诊,平均5.3 d。其中中指9 例,环指5 例,中、环指7 例。 结果 术后患者切口均Ⅰ期愈合。除1 例2 指肌腱粘连严重影响关节功能外,其余患者经积极锻炼,关节功能均恢复良好。20 例患者27 指获6 个月随访,1 例1 指失访。术后6 个月随访,采用总主动活动度(TAM)系统评定手指功能:获优12 指,良13 指,可2 指,优良率达92.6%。 结论 采取肌腱移植修复中、环指伸肌腱自发性断裂,术后手指关节功能恢复较好。

  • EXPERIMENTAL STUDY ON PERIPHERAL NERVE PLASTICITY IN RATS

    Objective To observe the plastic changes of sensory nerve in terms of structure and function when targetorgan changed through making the rat model of nerve regeneration by anastomosing the proximal end of sensory nerve and the distal end of motor nerve. Methods Thirty adult SD rats (male or female), weighing 200-250 g, were randomized into three groups (n=10 per group). The left upper l imb of the each rat was used as the experimental side, while the right upper l imb as the control side. In group A, the medial antebrachial cutaneous nerve was cut 5 mm away from its origin and its proximal end was anastomozed end-to-end to the distal end of musculocutaneous nerve. In group B, the musculocutaneous nerve was cut 5 mm away from its nerve entry point and the proximal end of medial antebrachial cutaneous nerve were anastomozed end-to-end to the distal end of musculocutaneous nerve. In group C, medial antebrachial cutaneous nerve and musculocutaneous nerve were cut, without further anastomosis. Twenty-four weeks after operation, the general condition and the motion of the elbow joint of rats, the wet weight and muscle fiber cross-section area of the biceps brachii as well as the latent period and the ampl itude of the evoked potential were observed and the acetylchol inesterase (AchE) staining of nerve of proximal end of anastomosis was conducted. Results All the rats survived for 24 weeks with good general condition and without wound infection. The rats in groups A, B and C were lost the active flexion of left elbow joint after operation. The rats in groups A and B got recovered to some degree at 24 weeks. The behavioral evaluation showed that there were 7 l imbs in group A and 5 l imbs in group B scoredas 4-5 points, there was a significant difference when compared with group C (P lt; 0.05), but there was no significant difference between group A and group B (P gt; 0.05). Group A and group B were superior to group C in terms of the wet weight and the muscle fiber cross-section area of the biceps brachii (P lt; 0.05), but no significant difference between group A and group B was detected (P gt; 0.05). The evoked potential of the biceps brachii and motor nerve fibers in proximal end of anastomosis could be detected in both group A and group B. But there was no significant difference between group A and group B with respects of function recovery of elbow joint, the latent period and the ampl itude of the evoked potential of the biceps brachii and the quantity of motor nerve fiber in proximal end of anastomosis (P gt; 0.05). Conclusion The change of target organ leads to the sensory nerve plasticity structurally and functionally, which may provide a new approach for peripheral nerve repair.
