Non-recoverable low radial nerve palsy and the outcomes of Smith's procedure of tendon transfer

Background: In the procedure of tendon transfer to treat low radial nerve palsy, recovering movement amplitude for toes is not difficult. It is more important to select the appropriate motive muscle. Previously, pillar muscle was commonly used as motivation for stretching fingers, but many authors opposed this because it\u2019s affecting the function of the hand. Objectives: To evaluate the clinical features of low radial nerve palsy and the outcomes of the treatment of non-recoverable low radial nerve palsy by Smith's procedure of tendon transfer. Subjects and methods: 36 patients suffering from irreversible low radial nerve palsy were treated by Smith's procedure of tendon transfer from Jan 2000 to Jan 2008. Mean follow-up was 23 months. Outcomes assessment was based on Tajima's criteria. Results: All 30 patients were satisfied with the operation and were greatly improved both their functional and aesthetic aspects. In term of biomechanics, the Flexor Carpi Radialis (FCR) is more suitable for reconstruction of the Extensor Digitorum Communis (EDC) in comparison with the flexor carpi ulnaris (FeU) or the power density spectrum. The patients showed good movements of the wrist and fingers/ the thumb moved independently with satisfactory extension and abduction/ the grip strength was rapidly improving. Conclusions: The use of the FCR for reconstruction of the EDC is a suitable choice and Smith's procedure of tendon transfer is a good procedure for the treatment of irreversible radial nerve palsy.

Treatment of large defects in the pelvic limb by dorsal vascularized muscular flaps or myo-cutaneous flaps

25 patients with defects of soft tissue or complex defects of soft tissue and bone joint in the pelvic limbs received the dorsal vascularized myocutaneous transplantation and monitored continuously within 3 months - 9 years. The results have shown that the operations had a good outcomes, even complex lesions of soft tissue and bone such as open bone fracture, osteitis, bone defect. The dorsal vascularized myocutaneous flaps had a good viability and high antisepsis so that can be used in the bone operation or plastic reconstruction for defects of soft infected subchronically or chronically

Study on the anatomy of dorsal muscular flaps in adult Vietnamese

The dorsal muscular flap was pedicular flap. The flap’s pedicle comprised a thoracic artery, a dorsolumbar nerve and vein of bulb. When coming into the dorsal muscle, 88.37% of thoracic arteries divided into 2 branches. Extra branch was far from the anterior edge of medial muscle about 1.95 cm and intra-branch was far from the supra edge of medial muscle about 2.69cm. The thoracic artery can supply fully the blood for the dorsal muscular flap.
