Objective To compare the curative effects of two different approaches in the surgical treatmentof small breast.Methods Fourty-seven patients with small breast were treated at our department.Twenty-eight sides of patients adopted an approach of prosthesis while the nineteen sides of patients were treated in the approach of autologous fat granules injection.Clinical assessment was done by analyzing operation time,blood loss volume,hospitalization duration and recent and long-term complications in breasts.All the pa-tients were followed up for thirty-two months on average.Results During follow-up period the appearance ofbreast was satisfied.Silicone gel breast prosthesis was well tolerated and the whole operation time was about (35±5 )min,the amount of blood loss was (35±5 ) mL,hospitalization duration was (2±1 ) days,during thefollow-up period prosthesis capsular contracture after hematoma occurred in one patient.The use of autolo-gous fat granules injection to breast augmentation was found limited,and the whole operate time was about (35±5 ) rain,the amount of blood loss was (15±5 ) mL,hospitalization duration was (1±1 ) days.With in-jection(2±l)times.During the follow-up period,one patient had infection,one patient liquefied fat,andone patient the induration.Conclusion Each treatment approach has its own advantages and disadvanta-ges.The approprite one should be selected according to the special situation of patients.

Objective To observe the clinical efficacy of percutaneous vertebroplasty (PVP) with percutaneous kyphoplasty (PKP) in the treatment of osteoporotic vertebral compression fracture(OVCF) by systematic review. Methods From September 2005 to March 2009,46 cases of fresh OVCF were treated. Patients were divided into 2 groups (A, B), according to Jikei grade, Genant semiquantitative method, injury vertebra number. Twenty-five cases(group A)were treated by PVP,8 males and 17 females with the age of 52 - 78 years (average 69). Vertebra segment of fracture was within T6 - L5 (14 in case thoracical vertebrae and 11 lumbar vertebrae). Twenty-one cases(group B)were treated by PKP,There were 6 males and 15 females with the age of 54 - 82 years (average 71). Vertebra segment of fracture was within T6 - L4 (12 in case thoracical vertebrae and 9 lumbar vertebrae). The clinical efficacy, incidence rate of complication, the anterior height of vertebrae body,visual analogue pain scale(VAS) ,ease of pain were measured preoperatively and at 6 weeks, 3 and 6 months and 1 year postoperatively between the two groups. Results All the patients were followed up for 12 -45 months with an average of 23.5 months. The average recovery of anterior height of vertebrae body was respectively(85.95 ± 4.31) % in group A and (93.64 ± 3.35) % in group B,which statistically difference in vertebral height between two groups (P ＜ 0.05). No statistical significant difference was seen in VAS, analgesic durg (AID) and ease of pain complication between two groups (P ＞0. 05). Statistical significant difference was noted in pre-postoperatively between intra-two groups (P ＜0. 05). Conclusions PVP and PKP can quickly relieve pain and enhance vertebral stability in treating thoracolumbar OVCF according to evaluation parameter, and have the similar therapeutic efficacy in treatment of OVCF with minimal invasion. However, PKP is superior in the recovery of vertebral height.
