Objective To study the method and effect of transferring the pedicled second metatarsal base for repairing bone defect of lateral malleolus. Methods Thirty lower limb specimens were anatomized to observe the morphology, structure and blood supply of the second metatarsal bone . Then transferring of thepedicled second metatarsal base was designed and used in 6 patients clinically.All cases were male, aged from 24 to 48 years old, and the area of bone defect was 3-4 cm. Results Followed up for 3-11 months, all patients healed primarily both in donor and recipient sites. There were excellent results in 4 cases and good results in 2 cases . The morphology and function of the malleoli were satisfactory. Conclusion Transferring of the pedicled second metatarsal base for repairing bone defect of lateral malleolus is an effective and reliable operative method.
From 1984 to 1993, 49 cases with varioussoft tissue defects around the knee were treated with pedicled calf myocutaneous flap, lateral sural cutaneous artery island skin flap, saphenous neurovascularskin flap and fasciocutaneous flap. The postoperation results were sucessful in 47 cases, and failure 2 cases, in one case with flap infection and theother with scar formation surrounding the knee. Both the failure cases were cured with split skin graft. The patient were followed up for an average of three and a halfyears, the knee function was almost completely regained, and the blood supply of the flaps, the elasticity and colour of the flaps were similiar to that of the normal skin, without being cumbersome. The sensation of the saphenous neurovascular flaps and the lateral suralcutaneous artery island flaps was preserved, except partial numbness was presented at the distal part of the flaps. Operative indications and selection of cases were discussed.
OBJECTIVE: To evaluate the clinical application of primary transfer of pectoralis major to reconstruct the elbow flexion and shoulder abduction. METHODS: 12 cases of old injury of branchial plexus with dysfunction of both elbow and shoulder joints were received surgical operation to reconstruct the palsy joints by primary transfer of pectoralis major, shoulder abduction was reconstructed by clavicular head and elbow flexion by sternal head respectively. All cases were followed up for 5 to 18 months. RESULTS: The function of both joints recovered obviously, the total superior rate is 91.7%. CONCLUSION: Only if the palsy joints, shoulder or elbow, remained normal or almost normal passive motion, and the muscle power of pectoralis major over 4 degrees, the primary transfer of pectoralis major should be a simple, reliable and convenient technique to reconstruct the palsy joints.
Fetal nerve grafts preserved at deep breezing were used to repair the peripheral nerve defects. The nerve directs included the sural nerves (removed as the donor nerve in repairing other nerve defects) in 5 cases, and digital nerve in 2 cases. All of them got good sensitive function. Patients were followed up for 1 yeas, all patients had gained comparatively good sensation. The surgical technique was introduced, and the validity of the transplantation of fetal nerve was discussed.
Rectus femoris muscle of the lower abdomen was used as myocutaneous flap in the reconstruction of the breast in 4 patients, of which, in 2 cases the reconstruction was carried out immediately following the radical mastectomy for breast cancer by using trancfer of the pedicled myocutaneous flap, and in the other two cases, the vascularized free myocutaneous flap was used 2 months and 5 years after the radical mastectomy, respectively. The vascularized free myocutaneous flaps were survived, however, in the pedicled myocutaneous flap group, the fat of the flaps had liquefaction 23 weeks after operation. The latter were healed after repeated dressings. The external appearance of the 4 reconstructed breasts lookedsattisfactory. The patients wete follwed up for 10 to 18 months, 2 patients hadno ill effects, while the 2 pedicled myocutaneous flaps, in which 1 patient hadbulging of the weakened abdominal wall, and the other had lost from follow up.
OBJECTIVE To investigate the therapeutical effect of treatment of ischemic necrosis of femoral head by the transfer of vascular pedicled iliac periosteum. METHODS From June 1983 to August 1997, 106 cases with ischemic necrosis of femoral head (II stage in 64 cases, III stage in 39 cases, IV stage in 3 cases) were treated by the transfer of vascular pedicled iliac periosteum with ascending branch of lateral femoral circumflex vessel or deep circumflex iliac vessel pedicle. RESULTS Followed up 2 years and 4 months to 16 years, there were excellent in 54 cases, better in 38 cases, moderate in 9 cases, poor in 5 cases, and 86.8% in excellent rate according to the criterion of the therapeutical effect on the repair and reconstruction of adult ischemic necrosis of femoral head. CONCLUSION Treating ischemic necrosis of femoral head by the transfer of vascular pedicled iliac periosteum has the advantage of constant pedicle, easily drawing materials and reliable therapeutical effect.
From March 1991 to October 1993, 6 the latissimus dorsi M. was transferred to reconstruct the flexor of the elbow following the injury of brachial plexus in 12 cases (8 males and 4 females). The average age was 31-year-old (6to 45-year-old). The patients were followed up for six months to two years. All of musculocutaneous flaps were survived. The contour of the upper arm was satisfactory. In 8 cases, the muscle strength was more than grade 4 and the active motion of the elbow was 135 degrees in flexion and 10 degrees in extension. The elbow could lift the load of l0kg. In 2 cases, the muscle strength was grade 4 and the active movement was 25 degrees in flexion and 25 degrees in extension. On 90 degrees flexion, the elbow could lift the load of 3kg. In 2 cases, the muscle strength was grade 3 and the active movement of elbow was 100 degrees in flexion 25 degrees in extension. Following the irreversible injury of the brachial plexus, the atrophy of the muscles was obvious. After the transfer of musculocutaneous flap, the circumference of the arm was increased while the tenseness of the skin was decreased. This faciliated the movement of the transferred muscle, improved the appearance of the upper limb and was convenient to observe the blood supply of the flap. When the brachial plexus was injuried at the root level, the latissimus dorsi M. was atrophied, after transfer of the nerve to the muscle, the function of the muscle recovered, then the tranferred muscle could be transferred to reconstruct the flexor of the elbow.
Objective To introduce the clinical experience of localdistally based turnover adipofascial flap for small to medium size wound of the extremities. Methods From 1994 to 2003, 33 cases of distally based longitudinal neuro-veno-adipofascial turnover adipofascial flap (axial perforator pattern in26, random pattern in 7) were transferred in the forearm (19) and lower leg (14).These flaps were all raised in the forearm or lower leg as local flaps. The length (pedicle plus flap) was 9 to 18 cm and the width was 3 to 4 cm, with L/W ratio of 3 to 5∶1. After transferring by 180° turnover, a splitthickness skin graft was used tocover the fascia surface. Results All the 33 flaps survived. The donor sites were closed directly, and the recipient sites were covered with full-or splitthickness skin grafts. Both donor and recipient sites healed primarily. Conclusion Turnover adipofascial flap is a simple and reliable method for small to medium size wound of the extremities.
Methodological quality and transferability will be important issues for the credibility and usefulness of both published studies and administrative methods for evaluating the socio-economic value of marketed medicines in China. This paper critically examines factors commonly contributing to, or inhibiting, the quality and transferability of socio-economic evidence of the value of medicines, with specific reference to the Chinese community. It discusses appropriate approaches to design, performance, and reporting of published economic evaluation studies, as well as guides on assessment of quality of economic evaluations and recommends two internationally established methods that may be suitable for training in this setting.
Objective To assess the long-time results of reconstruction of the extensor pollicis longus (EPL) function by transfer of the extensorindicis(EI). Methods From August 1978 to March 2003, 46 cases of loss of the EPL function were treatedby transfer of the extensor indicis. Of 46 cases, there were 32 males and 14 females, aged 16-51 years with an average of 36 years; there were 24 cases of oldtraumatic rupture and 22 cases of secondary rupture. The disease course was 2 days to 5 months, averaged 74 days. A specific EIEPL evaluation method (SEEM) wasused to measure the EPL function after transfer.Results Fortyone cases were followed up 9 years and 3 months on average (7 months to 23 years). Based on the SEEM, the results were excellent and good in 39 of 41 patients. The elevation deficit and combined flexion deficit were 0-2.2 cm (1.8 cm on average) and 0-3 cm (1.6 cm on average); the independent extension deficit was 0°-8° (5° on average). Conclusion Restoration of the extensor pollicis function by transfer of the extensor indicis is an effective and safe treatment option and the SEEM is a valid method for assessing EPL function.
