胫骨髁间棘撕脱骨折ppt课件

1、nThe modified classification of tibial intercondylar eminence fracture. （改良的Meyers McKeever分型更简单明了、易记 ）nA, Type I, nondisplaced.无移位 B, Type II, displaced anterior margin with an intact posterior cortex acting as a hinge. 前部移位张口、后部以骨皮质铰链 C, Type III,completely displaced and void of all bony contact.

2、完全移位，骨质无连接 D, Type IV, comminuted.移位并粉碎 nNonsurgical ManagementType IThe knee should be immobilized in a position of comfort. Immobilization in approximately 20 of flexion has been recommended建议屈曲20固定nRadiographic union is seen after 6 to 12 weeks, at which time the cast may be removed and weight be

3、aring and range-of-motion (ROM) exercises initiated.（6-12周平片可见骨质连接，早期即行支具保护下功能活动锻炼）nType II Type II fractures can be managednonsurgically when successful closedreduction is achieved.闭合复位成功2型亦可非手术治疗nSurgical Management Recent advances in arthroscopic technique have led to a trend of arthroscopic fixa

4、tion for type II, III, and IV tibial eminence fractures.I型保守治疗III型手术治疗基本已成定论对于II型骨折的治疗仍有争议。 Rehabilitationndepends on the quality of fixation, npatient compliance,nthe nature of the fracture. RehabilitationnType I fractures should be immobilized for 2 to 6 weeks, followed by protected ROM and weight

5、 bearing. （preadolescent ）nIsometric quadriceps muscle exercises should be performed throughout the immobilization period to minimize disuse atrophy.nThe risk of stiffness after surgicalfixation of tibial eminence fracturesis greatly increased compared withnonsurgical management; thus, earlyROM is recommended followingsurgical managementnImmediate weight bearing and ROM may be allowed for fractures that are rigidly fixed using screws, whereas longer per
