摘要目的 探讨改良Smith Peterson入路行髋臼周围截骨术(periacetabular osteotomy,PAO)治疗成人髋关节发育不良(developmental dysplasia of the hip,DDH))的近中期疗效。方法 回顾分析泉州市正骨医院2018年4月至2021年1月采用改良Smith Peterson入路行PAO治疗的21例成人DDH,其中男1例(1髋),女20例(20髋);左髋12例,右髋9例;年龄18~44岁,平均(32.15±10.81)岁;改良T-nnis骨关节炎分期0期5例(5髋),Ⅰ期14例(14髋),Ⅱ期2例(2髋)。记录所有患者术中出血量、手术时间、住院时间、并发症发生情况以及术前术后髋关节Harris评分,通过X线片记录所有患者外侧中心边缘(lateral center edge,LCE)角、臼顶倾斜角(T-nnis角)、股骨头超出指数(extrusion index,EI)及前方中心边缘(anterior center edge,ACE)。结果 患者术中出血量(779.52±29.60)mL,手术时间(115.95±4.44)min,住院时间(7.29±0.35)d。术后均获得随访,随访时间24~48个月,平均(33.73±9.12)个月。所有患者均未出现血管损伤、髋臼后柱骨折、切口愈合不良、感染、下肢深静脉血栓。2例(2髋)术后出现股外侧皮神经支配区麻木,未予特殊处理,术后3个月后自行恢复。末次随访Harris评分(89.67±3.44)分优于术前(72.67±4.32)分,差异有统计学意义(P<0.05)。术后12个月X线片示所有患者截骨均愈合,均未出现截骨块骨坏死。术后LCE角(31.67±3.86)°优于术前(9.86±3.25)°,T-nnis角(6.57±2.44)°优于术前(15.05±2.48)°,EI(11.33±2.96)%优于术前(29.19±2.89)%,ACE角(30.67±3.71)°优于术前(8.62±3.31)°,差异均有统计学意义(P<0.05)。结论 改良Smith-Peterson入路行PAO治疗成人DDH严格把控手术适应证,重视常见手术并发症的防治,可有效改善髋关节骨性覆盖,显著改善髋关节功能,近中期疗效满意。
Objective To evaluate early and mid term effectiveness of periacetabular osteotomy(PAO)through modified Smith Peterson for development dysplasia of the hip (DDH)in adults.Methods 21 adults with DDH underwent PAO through modified SmithPeterson at Quanzhou Orthopaedics Hospital between April 2018 and January 2021.There were 1 male (1 hip) and 20 females (20 hips) containing 12 left hips and 9 right hips.The ages ranged from 18 to 44 years with a mean of (32.15±10.81)years.Among them,5 cases (5 hips) were categorized as modified T-nnis stage 0,14 cases (14 hips) as stage I,and 2 cases (2 hips) as stage Ⅱ.Intraoperative blood loss,surgical duration,hospitalization duration,occurrence of complications and preand post-operative Harris hip scores were recorded.Imaging assessments included lateral center edge(LCE) angle,acetabular inclination angle (T-nnis angle),extrusion index (EI),and anterior center edge (ACE) measured via X-rays.Results Bleeding volume was (779.52±29.60)mL,operation time was (115.95±4.44)min,the length of hospital stay was (7.29±0.35)days.Follow-up of all patients was (33.73±9.12)months (range 24~48 months).There were no complications such as vascular injury,fracture of posterior column of acetabulum,poor wound healing,infection,deep venous thrombosis of lower extremity.Postoperative numbness of the lateral femoral cutaneous nerve occurred in 2 adults(2 hips) and disappeard postoperatively 3 months without special treatment.At last follow up,Harris hip score was (89.67±3.44),significantly better than preoperative ones (72.67±4.32)(P<0.05).At 1 year after operation,X-ray films showed that the all osteotomies healed and there was no osteotomy block osteonecrosis.Postoperative LCE angle was (31.67±3.86)°,significantly better than preoperative ones (9.86±3.25)°(P<0.05).Postoperative T-nnis angle was (6.57±2.44)°,significantly better than preoperative ones(15.05±2.48)°(P<0.05).Postoperative EI was (11.33±2.96)%,which was significantly better than preoperative ones (29.19±2.89)% (P<0.05).Postoperative ACE angle was (30.67±3.71)°,which was significantly better than preoperative ones (8.62±3.31)°(P<0.05).Conclusion If the indications for surgery are strictly controlled and prevention and treatment of common surgical complications are payed attention to,PAO through modified Smith Peterson for DDH in adults can effectively improve the osseous covering of hip joint and significantly improve hip joint function,providing satisfactory early and mid-term clinical outcome.
