[Risk factors of pinhole infection in the fractured lower limbs after external fixation: a case-control study].

Objective: To investigate the risk factors of pinhole infection in the fractured lower limbs after external fixation.

Methods: The case-control study was designed. From May 2009 to May 2014, the clinical data of 272 patients with lower limb fracture treated by external fixation device were collected.

[Anatomic study and clinical application of thinned posterior tibial artery perforator flap].

Objective: To explore the feasibility and therapeutic effect of thinned posterior tibial artery free perforator flap for the reconstruction of soft tissue defects at dorsum of hands.

Methods: Six fresh adult lower limbs specimens were injected with red latex via arterial cannula and dissected. The number, distribution, branches, and outer diameter of posterior tibia artery perforators were observed.
