To explore the suitable division of male genitalia subunits and the effectiveness of large-area perineum defect repair under its guidance. According to the anatomical and functional characteristics of male genitalia, the subunit division scheme was proposed area Ⅰ, glans penis; area Ⅱ, body of penis; area Ⅲ, scrotum; area Ⅳ, scrotum. Between April 2017 and July 2019, 12 patients with large genitalia defects were treated, with an average age of 60.9 years (range, 57-66 years) and an average disease duration of 2.7 years (range, 2-5 years). The defect area involved area Ⅰ in 1 case, area Ⅱ in 7 cases, area Ⅲ in 5 cases, and area Ⅳ in 8 cases; the size of area ranged from 6 cm×4 cm to 23 cm×16 cm. The causes of defect included 3 cases of trauma, 6 cases of Paget disease, 2 cases of squamous cell carcinoma, 1 case of spindle cell tumor. According to the design of the corresponding repair scheme, the main repair methods were to rotate and advance the skin flap and pedicled skin flap in the same area. When the ysiological appearance and function, and has positive clinical significance. The subunits of male genitalia can be used to guide the repair of the defect, which can better restore the physiological appearance and function, and has positive clinical significance. To compare the short-term effectiveness and safety of unipedicular versus bipedicular percutaneous kyphoplasty (PKP) for osteoporotic vertebral compression fracture (OVCF) with posterior wall broken. The clinical data of 68 patients with OVCF with posterior wall broken and without posterior ligament complex injury and spinal cord nerve injury between June 2013 and December 2018 were retrospectively analyzed. According to the different operative approaches, the patients were divided into two groups group A (36 cases received PKP via bilateral pe
