Case Reports Comparative Study[A comparative study on two different absorbable intramedullary nails in treating metacarpal and phalanx fractures].
To study the effect of two different absorbable intramedullary nails in treatment of metacarpal and phalanx fractures. ⋯ In the PDLLA group(n = 24), the rejection occurred in 8 cases 3-4 weeks after operation. PDLLA nails were taken out in 6 of the 8 cases after 5-10 days of operation and bone healing was achieved 2 months after re-fixation by Kirschner wire; the rejection subsided in the other 2 cases after 25 days of conservative treatment, and bone fracture healed after 14 weeks. No rejection was observed with primary healing in the other 16 cases of the PDLLA group. In PDLLA + chitosan group(n = 36), the rejection occurred in 1 case 19 days after operation, but the rejection subsided after 3 days of conservative treatment. No rejection was observed in the other 35 cases with primary healing. All patients were followed up 4-11 months with an average of 6 months. No rejection was observed and bone healing was achieved during the follow-up. The time of bone healing was 6-16 weeks (8 weeks on average). There was statistically significant difference in the curative result between two groups(P < 0. 05). Conclusion Intramedullary nail of PDLLA was very suitable to fix fractures of metacarpal and phalanx. During the degradation of PDLLA, the acidic products can cause rejection. When PDLLA mixed with chitosan, PDLLA can not only strengthen the intensity but also neutralize the acidity. So the rejection can be decreased. PDLLA intramedullary nails composed of chitosan were better than PDLLA intramedullary nails in clinical treatment of metacarpal and phalanx fractures.

[Experimental study of posterior pedicle screw placement on atlas].
To assess the possibility of placing the posterior pedicle screw on atlas. ⋯ C1 posterior pedicle screw fixation is quite accessible and safe, but the surgeons should pay attention to the angle and the depth of the screw placement.
