Abstract

OBJECTIVE

Minimally invasive, sufficiently stable for movement and partial weight bearing, osteosythesis of pertrochanteric femoral fractures in children < 6-8 years using elastic, stable intramedullary nailing (ESIN).

INDICATIONS

Proximal, pertrochanteric femoral fractures Delbet type IV in children < 6 years.

CONTRAINDICATIONS

Comminuted fractures, femoral neck fractures.

SURGICAL TECHNIQUE

By inserting three elastic titanium nails (TEN), prebent in the proximal third, retrograde into the femur, a stable 3‑point support stabilizes the proximal fragment. For further improvement of stability, EndCaps can be used.

POSTOPERATIVE MANAGEMENT

Partial weight bearing (sole-contact) for 4-5 weeks. X‑ray controls immediately after surgery and after 4-5 weeks. No sports for 3 months.

RESULTS

In our patient population we have good experience with this technique for very rare pertrochanteric fractures in children younger than 6-8 years. With minimally invasive access, exercise-stable administration can be achieved without a pelvic leg cast.

摘要

目的

使用弹性稳定髓内钉(ESIN)对6 - 8岁以下儿童股骨转子周围骨折进行微创治疗,使其在活动和部分负重时具有足够稳定性。

适应症

6岁以下儿童近端股骨转子周围骨折(Delbet IV型)。

禁忌症

粉碎性骨折、股骨颈骨折。

手术技术

通过插入三根在近端三分之一处预弯的弹性钛钉(TEN),逆行插入股骨,形成稳定的三点支撑以固定近端骨折块。为进一步提高稳定性,可使用EndCaps。

术后管理

部分负重(足尖着地)4 - 5周。术后及4 - 5周后进行X线检查。3个月内禁止运动。

结果

在我们的患者群体中,对于6 - 8岁以下儿童极为罕见的股骨转子周围骨折,我们在这项技术方面有良好经验。通过微创入路,无需骨盆腿部石膏固定即可实现运动稳定的治疗。
