Abstract

Purpose

The purpose of this study was to introduce the “Callus bending technique” following gradual bone lengthening for functional reconstruction. We report cases of segmental phalangeal loss with replanted incomplete amputation and distal finger amputation.

Methods

Herein, we report two cases to introduce the “callus bending technique”: one in which the “callus bending technique” was adopted after gradual bone lengthening for amputated digital stumps, and the other, a case of incomplete digital amputation, in which defects in the replanted middle phalanges were filled by distraction lengthening of the proximal phalanx, followed by use of the callus bending technique.

Results

The patients could almost touch their palms with the tips of their injured fingers when they flexed their metacarpophalangeal joint of the digit fully. When he extended the metacarpophalangeal joint of the injured fingers fully, the hand looked almost natural, and he could push a table. For the patient with incomplete digital amputation, the distal interphalangeal joint was also reconstructed using the joint surfaces of the distal and proximal phalanges.

Conclusions

Both patients were satisfied with both the functional and cosmetic improvement of their fingers and returned to their work as carpenters. In both cases, an external fixator, the Ilizarov minifixator, was used, as it affords relatively great flexibility.

Clinical relevance

Adoption of this technique involves the use of multiple surgical procedures, but it eventually yields reasonable cosmetic and functional results. We propose the use of this technique as the technique of choice for amputated fingers or severe bone loss due to trauma.
渐进式骨延长后的“骨痂弯曲技术”用于指截指骨缺损的功能重建:2例报告
目的介绍渐进式骨延长后的“骨痂弯曲技术”用于骨功能重建。我们报告的病例节段性指骨损失与再植不完全截肢和远端手指截肢。方法本文报道2例“骨痂弯曲术”:1例为断指残端骨逐渐延长后采用“骨痂弯曲术”;另1例为不完全断指,采用近端指骨牵张延长术填补中指骨缺损,再应用骨痂弯曲术。结果当患者充分屈曲手指掌指关节时,患者的指尖几乎可以接触手掌。当他完全伸展受伤手指的掌指关节时,这只手看起来几乎是自然的,他可以推桌子了。对于指端不全截肢患者,采用远端和近端指骨关节面重建远端指间关节。结论2例患者手指功能及美观均得到满意改善,恢复木工工作。在这两种情况下,都使用了外固定架Ilizarov微型固定架,因为它提供了相对较大的灵活性。临床应用该技术涉及多种外科手术,但最终可获得合理的美容和功能效果。我们建议使用这种技术作为选择的技术截肢手指或严重的骨质流失由于创伤。
