To evaluate the use of small fragment implants for fractures of the proximal tibia.
Retrospective.
Level I trauma center.
PATIENTS/PARTICIPANTS: Seventeen patients with AO Classification Type B and C fractures of the proximal tibia. Two patients were lost to follow-up.
After atraumatic dissection and open reduction, fracture stabilization was accomplished with the use of the AO/ASIF small T-plate (3.5-millimeter system). In two patients a medial uniplanar external fixator was applied as additional fixation. In six patients a cancellous autograft was performed.
At an average follow-up of forty-two months (range, 24 to 75 months), all patients were evaluated radiographically and functionally. The incidence of local complications was specifically recorded.
Postoperatively, the radiographs showed 86.7 percent anatomic or near anatomic reduction with respect to the articular joint surface. In three separate patients condylar widening, condylar narrowing or varus deformity was evident. In one patient, a minimal secondary displacement of less than two millimeters was observed before bony healing. All fractures healed within twelve weeks. At the latest follow-up, there were 53.3 percent excellent, 33.3 percent good, and 13.3 percent fair results. There were no infection or soft tissue complications.
The use of small fragment implants combined with atraumatic soft tissue dissection potentially offers good results for the treatment of fractures of the proximal tibia. These initial results suggest that this technique may have the advantage of anatomic reduction while comparing favorably with less invasive methods regarding radiologic and functional outcome as well as incidence of complications.
评估小型接骨板植入物在胫骨近端骨折中的应用。
回顾性研究。
一级创伤中心。
患者/参与者:17例胫骨近端AO分型B型和C型骨折患者。2例患者失访。
在进行无创解剖和切开复位后,使用AO/ASIF小型T形接骨板(3.5毫米系统)实现骨折固定。2例患者应用内侧单平面外固定器作为辅助固定。6例患者进行了松质骨自体移植。
平均随访42个月(范围24至75个月),对所有患者进行影像学和功能评估。特别记录局部并发症的发生率。
术后X线片显示,相对于关节面,86.7%达到解剖复位或接近解剖复位。3例患者出现髁部增宽、髁部变窄或内翻畸形。1例患者在骨愈合前观察到小于2毫米的轻微二次移位。所有骨折均在12周内愈合。在最近一次随访时,结果为优的占53.3%,良的占33.3%,可的占13.3%。无感染或软组织并发症。
小型接骨板植入物联合无创软组织解剖可能为胫骨近端骨折的治疗带来良好效果。这些初步结果表明,该技术可能具有解剖复位的优势,在影像学和功能结果以及并发症发生率方面与侵入性较小的方法相比具有优势。
