ABSTRACT
BACKGROUND: With the aging of the population, the incidence of distal radius fracture is gradually increasing. Non-operative external fixation splint can reduce the economic burden, mental burden and prevent surgical trauma. Therefore, the study of external fixation splint for distal radius fracture has important clinical value and significance. OBJECTIVE: To summarize the research status of distal radius fracture fixation splints and to lay a foundation for further research. METHODS: The first author searched the CNKI, Wanfang and VIP database, PubMed, Embase and Web of Knowledge for studies regarding external fixation splint for distal radius fracture published from 2000 to 2019. The key words were “distal radius fracture, external fixation, splint” in Chinese and English. RESULTS AND CONCLUSION: (1) The improved design of the shape, material and fixation band of the traditional small splint is the key direction of splint research at present. The improved design of splint shows great advantages in clinical application. (2) With the advancement of social science and technology, the emergence of new materials, new technologies and the deepening of biomechanical research, distal radius fracture fixation splint integrated with the elements of modern science and technology is the development trend of small splint in the future.
ABSTRACT
PURPOSE: To access the efficacy of a modified design of a reverse superficial sural artery flap (RSSAF) to decrease the level of venous congestion and flap necrosis. MATERIALS AND METHODS: Twenty four cases of RSSAF were performed. The mean age of the patients was 47 years and the mean follow up period was 21 months. The average size of the flap was 7.4x5.2 cm. There were 19 cases of the modified flap design and 5 cases of non-modified design. The venous congestion and complications were analyzed according to the modification of the flap design. RESULTS: The flap survived in 23 cases. Primary closure of the donor site was performed in 11 cases whose flap width was <5 cm, and 12 cases required a skin graft. Venous congestion was observed in 5 cases including 4 cases, who were not treated with the modified design and 1 case with arterosclerosis obliterans preoperatively. Partial flap necrosis occurred in 2 flaps that did not have the modified design. CONCLUSION: The modified RSSAF with a skin extension over the pedicle to decrease the tension of the tunnel is an effective procedure for reconstructing the lower extremity, which can prevent venous congestion and improve the survival rate of the flap.
