Results All flaps survived, and no postoperative complications occurred. The followed-up time ranged from 12 months to 36 months, and the texture of flap was flexible. No bulky was noted, and skin color was similar to the hand skin. The flexor and extensor function of wrist recovered satisfying. The 2-point discrimination of flap ranged from 9 mm to 15 mm (12.5 mm on average). Conclusion Free chimeric anterolateral thigh cutaneo-tendinous flap with rectus femoris muscular flap is a good option for repairing the complex tissue defect of dorsum wrist.
RESUMEN
Objective To explore the efficacy of peroneus brevis tendon transfer and peroneal tendofascial flap for repairing achilles tendon and overlying skin defect.Methods From April,2004 to May,2015,5 cases of achilles tendon and overlying skin defect were treated with peroneus brevis tendon transfer and peroneal tendofascial flap.In these cases,the length of the achilles tendon defect was from 3.0 cm to 8.0 cm,and the size of skin defect ranged from 2.0 cm × 3.0 cm to 3.0 cm × 5.0 cm.Using peroneus brevis tendon to reconstruct achilles tendon defect,and covered with peroneal tendofascial flap,and then skin graft.One of them combined with the gastrocnemius tendon V-Y advancement to promote the reconstruction of achilles tendon longer defect.The patients were followed-up regularly,and evaluated by the American Society of Ankle Arrhythmia (AOFAS) ankle-hindfoot scoring system.ResultsAll operations were successful and the grafted skin survived.All cases were followed-up from 6 months to 10 years with an average of 5.2 years.At the time of last followed-up,all wounds healed well without re-infection and ulceration.Not foot varus deformity and the strongth was back to the level before the injury.AOFAS ankle-hindfoot score was increased from (50.44 ± 12.05)(preoperative) to (90.02 ± 6.55)(the last follow-up) (P＜0.05).Conclusion There were some advantages in the method of the treatment of achilles tendon and overlying skin defect by using peroneus brevis tendon transfer and peroneal tendofascial flap,such as easy to cut,small damage to the donor area,and no significant deformity to the receptor area,etc.It is a good way to repair achilles tendon and overlying skin defects.

Methods The data was reviewed from June 2006 to June 2010, which the thigh anterolateral free flap with iliotibial tract were used to repair the defects of the tendon and skin of back of hand in 12 patients. The skin flap was 7 cm´10 cm~8 cm´12 cm in area. The iliotibial tract was 7~13 cm in length and 8~10 cm in width. Institute of Hand Surgery of Chinese Medical Association was to assess the effect. The fellow-up of the 12 patients was 6 months~4 years. Results All the flaps survived after the operation. The result showed excellent in 3 patients, good in 6 and fair in 3. Conclusion It is an effective surgical method to repair the tissue defects of the tendon and skin with thigh anterolateral free flap with iliotibial tract.
RESUMEN
Objective To investigate the biomechanics of the tissue engineered tendons which use the embryonic tendon cells as the seed-cells and the silk as the scaffolds. Methods Two groups were set up with one as the group with tenocytes and the other as the group without tenocytes. Tissue engineered tendons were taken out at 2-week, 4-week, 6-week, 8-week post-operation, with 20 samples per-group each time. The values of biomechanics were measured and analyzed using the software SPSS 13.0. Results The biomechanical properties of the tissue engineered tendons in the group with tenocytes were significantly better than those in the group without tenocytes (P<0.05). In the group with tenocytes, the vitodynamics results got better with the increase of implantation time (P<0.05) except for the results of 8-week post--operation(P>0.05). But in the group without tenocytes, only the results of that from 8-week post-operation were of significant significance (P<0.05). Conclusion The results presented in the current study demonstrated that silk could stick tenocytes well, hold the characteristics of great resistance to draw after adhesion of tenocytes, and formed the tissue engineered tendon gradually in chickens, suggesting its potential application in the treatment of the defect of tendon.
RESUMEN
Various reconstructive surgery have been performed for repair of the patellar tendon defect due to direct trauma or infected open wound. But most surgical procedure need wide skin incision and soft tissue dissection, that result in joint stiffness or muscle weakness. We carried out two-stage reconstructive surgery used bone-patellar tendon-bone allograft and bioabsorbable interference screw for skin and patellar tendon defect due to repetitive debridment for infected wound management. The result was satisfactroy and the patient achieved nearly full return of knee motion and quadriceps strength.

RESUMEN
Objective To provide a clinical anatomic basis for the bi-pedicled gastrocnemius myocuta- neous flap which is to be used to repair defects of the Achilles tendon and posterior skin of the ankle.Methods In anatomic study,out of 30 cadaver specimens,bi-pedicled V-Y gastrocnemius myoeutaneous flaps were harvested to measure the downward sliding lengths of the flap when the knee was at flexion of different degrees.In clinic,12 patients with the Achilles tendon and posterior ankle skin defects were repaired with the bi-pedicled gastrocnemius myocutaneous flaps.The areas of composite defects ranged from 10 cm?6 cm to 6 cm?4 cm.They were followed up for four months to 12 years.Results The maximal sliding length of the flap reached (9.2?0.9)cm when the knee was at flexion of 90?.All the clinical flaps survived and ambulation of the patients recovered.The dorsiflexion and plantarflexion of the ankles reached 11.0??1.4?and 35.0??4.6?respectively.Conclusion This flap is suitable for one-stage repair of composite Achilles tendon defects.
RESUMEN
Objective To introduce a new surgical method of reconstructing A ch illes tendon by transfer of the soleus tendon flap. Methods The method was desig ned on the basis of the anatomical characteristics of the superficial muscles as sociated with Achilles tendon. It was applied to treat 12 patients with Achilles tendon defects. These patients were followed up for 0.5 to 6 years (average 39 months). Results The curative effect of the method were assessed according to Ar ner-Lindholms evaluation criteria. 9 cases were rated as excellent, 2 fine an d 1 poor, with the total excellent and fine rate being 92%. Conclusions ①Misdi agnosis and improper initial treatment are the major causes of Achilles tendon d efects. ②Systematic training after operation is very important for good curativ e effects. ③The method mentioned above brings about less trauma, less negative effects on blood supply to Achilles tendon, and good healing after operation.
RESUMEN
Open defect of the Achilles tendon with loss of overlying skin is very difficult to treat. This condition poses problems of combating infection, providing soft-tissue cover and bridging the gap in the tendon. This has been generally managed in multi-staged procedures. Once the infection is brought under control with debridement and antibiotics, skin cover is provided by the flap. The tendon itself is reconstructed later by a conventional technique. More recently, composite free-tissue transfers repairing the skin and tendon in a single stage have been reported. We describe a simple and very reliable one-stage procedure, using a lateral supramalleolar island flap, a fascia lata autograft and a peroneus brevis tendon transfer, which helps tendon units bridge the gap in the Achilles tendon, and thin and mobile skin to cover the defect in the skin. Our patient showed good result, so we report this case with a review of the literature.
