ABSTRACT

BACKGROUND:Dorsal digital block refers to the commonly used anesthesia for adults in smal or moderate hand injury surgeries, but in recent years, modified transthecal digital block technique is gradualy respected, which is favored with a rapid and good effect and fewer complications. OBJECTIVE:To evaluate the clinical anesthetic outcomes of modified transthecal digital block and traditional dorsal digital block technique for the treatment of hand injury of adults in emergency by a prospective randomized controled study. METHODS:Totaly 60 adult patients with hand injury were enroled and divided into two groups of modified transthecal digital block and traditional dorsal digital block randomly. Blocks were performed by one single surgeon. The operation time, local anesthetic dose, onset time of anesthesia, duration of anesthesia, success rate of anesthesia, visual analogue scale scores and complications were recorded. RESULTS AND CONCLUSION:The anesthesia effects in the two groups were acceptable. There was no significant difference in the onset time of anesthesia, duration of anesthesia, success rate of anesthesia and complications between the two groups (P > 0.05). The operation time of anesthesia, local anesthetic dose, and visual analogue scale scores were significantly different between the two groups (P< 0.05). Modified transthecal digital block is more convenient and has less pain than the traditional root digital block, which is a safe and reliable anesthetic technique.

ABSTRACT

Objective To report the anatomical study and clinical application of the free peroneal perforator-based sural neurofasciocutaneous flap. Methods Latex injection studies were performed on 10 adult cadaveric lower limbs. The presence, prevalence, and location of the peronel perforators that were suitable for vascular anastomosis were documented. From April 2007 to January 2010, 6 patients with large soft tissue defects in the upper limb underwent the reconstructive procedures with the free peroneal perforatorbased sural neurofasciocutaneous flap transfers. 4 patients were men and 2 were women, with the age ranging from 19 to 60 years. The causes of the injury included 4 motor vehicle accidents, and 2 massive machinery trauma. The area of the flap ranged from 16 cm × 8 cm to 30 cm × 10 cm, and the length of the perforator pedicle was 4 cm to 6 cm. Results A mean of 5.3 perforating vessels of the peroneal artery was noted in the specimen. The peroneal perforator that located at the junction of the middle and lower thirds of the fibula was found suitable for microsurgery, with the external diameter and the length being (1.21 ± 0.13)mm and (4.6 ± 0.8)cm respectively. All the 6 flaps survived completely without necrosis. No severe venous congestion was observed. All the patients were satisfied with the aesthetic outcome postoperatively at 3 to 12 months'follow-up. There were no major donor site complications. Conclusion The free sural neurofasciocutaneous flap based on a single peroneal perforator is an excellent tool for reconstruction of extensive soft tissue defects in the upper limb.

ABSTRACT

@#Objective To report the technique and effect of distally based, cross-leg, anterolateral thigh flap for reconstructing the soft tissue defects in middle and distal thirds of the contralateral leg. Methods Five patients of soft tissue defects in lower legs associated with injuries to the eontralateral legs were treated with distally based, cross-leg, anterolateral thigh flaps of the contralateral limbs. Results After the pedicle division at 6 weeks postoperatively, the 5 flaps all survived. And the blood supply of flaps remained steady when followed up for 12 to 15 months. The flaps possessed favorable contours, and allowed successful secondary repair of injured bones or tendons. The donor sites healed primarily, and no influence was observed to the donor limbs. Conclusion For the soft tissue defects in middle and distal thirds of leg associated with damage to the surrounding tissues and arterial injury of the contralateral leg, cross-leg transplantation of the contralateral distally based anterolateral thigh flap is a good option of reconstruction.

ABSTRACT

Objective To explore the possibility of treating tibial osteomyelitis with transfer of a compound flap composed of the sural nerve fasciocutaneous flap and the lateral gastroenemius muscle.Methods We observed in cadaver specimens the anatomical structure of the sural nerve fasciocutaneous flap and the lateral gastrocnemius muscle to design a compound flap. Fifteen cases of tibia] osteomyelitis were treated with sinus excision and thorough debridement before the skin defect area was covered with a sural nerve compound flap whose muscle was stuffed into the tibia] channel. Plates were replaced with unilateral fixators in 3 cases of tibial nonunion. Results We observed 5 to 6 perforating branches of blood vessels between the sural nerve fascioeutaneous flap and the lateral gastroenemius muscle, indicating that the two can be harvested simultaneously in one compound flap. The transferred compound flaps survived in 15 cases. Tibial os-teomyelitis was completely cured in 14 cases, 1 case healed after second debridement, and 3 cases of tibial nonunion healed 6 months later after a second stage iliac bone graft. No recurrence was found after a mean follow-up of 18 (10 to 26) months. Conclusion A compound flap composed of the sural nerve fascio-cutaneous flap and the lateral gastrocnemius muscle can be used to treat tibia] osteomyelitis effectively.

ABSTRACT

BACKGROUND: The articular surface of interphalangeal joint and metacarpophalangeal joint is destroyed or defected, that would remain serious sequela in many patients and affect patient's routine work and living. Therefore, therapeutic efficacy of finger joint damage determines the functional recovery of hands. Tissue engineering provides a novel pathway for finger joint damage. OBJECTIVE: To summarize the research progress on the repair and reconstruction of finger joint damage. RETRIEVAL STRATEGY: The researcher of this article used the computer to retrieve literatures of Pubmed database with docuterms of "Interphalangeal joints fractures, Metacarpophalangeal joints fractures, Finger osteoarticular, Reconstruct", and the language was defined to English. Meanwhile China Academic Journals Full-Text Database from 2000 to 2007 was also retrieved with docuterms of "Interphalangeal joints, Metacarpophalangeal joints, Fractures, Repair and reconstruct", and the language was defined to Chinese. Totally 106 correlated articles were screened out and the data were firstly checked. Inclusion standard: ①closely correlated to the repair and reconstruction of finger joint damage; ②those published in the near future or authorized journal in the same field were preferred. Exclusion standard: repetitive investigation. LITERATURE EVALUATION: The resource of literatures was the clinic empirical studies of the repair and reconstruction of finger joint damage. Among 32 included articles, 3 of them were reviews and the others were clinic or empirical studies. DATA SYNTHESIS: The homogeneity variant bone-joint transplantation has got some successes in clinic, but how to prolong the survival time of transplanting joints would be a new research topic. Autoallergic joint transplantation is a good method to treat the defects of finger joints, but how to make handling conveniently, diminish secondary damage and search new donor site, all deserve to research. The ideal therapeutic efficacy of the finger joint damage is anatomical reset of the joint profile, that can reduce traumatic arthritis and anchylosis at the minimal level. But it is still a tough problem in the fingers joint's repairs, because of the multiple structure of bone-joint in hands and trauma factors. Open reduction and internal fixation, skeletal traction, arthroplasty, fusion of joint, prosthetic replacement of joint, articular transplantation and bone-joint tissue engineering have all obtained success, but none can fully succeed or be generally adopted. CONCLUSION: There are many treatments of the finger joint damage, but their results are not very well. With the research of homogeneity variant bone-joint transplantation, autoallergic joint transplantation and tissue engineering development, bone-joint transplantation will have a wide prospect in treatment of finger joints damage.
