    Abstract:
    OBJECTIVE: To sum up the clinical characteristics, surgical management, and effectiveness of pressure sore of sinus type. METHODS: Between January 2009 and April 2013, 17 patients with 19 pressure sores of sinus type after traumatic paraplegia were treated, and the clinical data were analyzed retrospectively. There were 11 males and 6 females with an average age of 27.4 years (range, 17-49 years). The median disease duration was 1.5 years (range, 6 months to 7 years). Of 17 cases, there were 14 primary cases and 3 recurrent cases; 10 focuses of 8 cases were classified as simple sinus type, and 9 focuses of 9 cases as complex sinus type, which had a false synovial sheath complicated with one to four "second sinus". The pressure sore of sinus type majorly located at the ischial tuberosity. The size of pressure sore ranged from 1.5 cm x 1.0 cm to 3.0 cm X 2.0 cm, and the length of "second sinus" ranged from 8 to 32 cm with an average of 17 cm. After the false synovial sheath was totally excised, the wound was repaired by local sliding or rhombus flaps at the first or second stage in patients with simple sinus type pressure sore. On the basis of excising the false synovial sheath, the "second sinus" was totally removed in the patients with complex sinus type pressure sore. RESULTS: Wound dehiscence occurred in 1 case of simple sinus type pressure sore at 4 days, which was cured after it was sutured again. Wound infection occurred at 9, 17, and 23 days respectively in 3 cases of complex sinus type pressure sore, which was cured after second debridement and necrosis tissues removal. The other wounds healed by first intention, and the flaps totally survived. All patients were followed up 6-12 months (mean, 9.3 months). No recurrence was observed. CONCLUSION: According to the clinical characteristics, pressure sore of sinus type could be divided into simple sinus type and complex sinus type. The key of successful treatment is to thoroughly excise false synovial sheath and "second sinus".
