[Clinical analysis on replantation of severed palm in 45 patients].

OBJECTIVE: To explore methods and clinical outcomes of microsurgical technique in treating patients with severed palm. METHODS: From January 2009 to December 2012,45 patients with severed palm were treated by replantation through microsurgical technique, included 37 males and 8 females, aged from 13 to 45 years old with an average of 25. Postoperative survival rate and evaluation standard of upper limb replantation function posposed by Chinese Medical Association were applied for evaluate clinical outcomes after operation. RESULTS: Forty-five patients with severed plam were treated by replantation. Thirty-nine patients (121 fingers) were survived,and survival rate was 87%. All patients were followed up 3 to 15.5 months with an average of 11.5 months. According to evaluation standard of upper limb replantation function posposed by Chinese Medical Association, the total score was 80.27 +/- 1.93, and 27 cases got excellent results, 8 good and 4 poor. CONCLUSION: The success of replantation of severed palm depends on grasping operation indication strictly, knowing complexity and local anatomic relationship, debridement completely during operation, making full use of remaining organization, arteriovenostomy through microsurgical technique as early as possible, constructing circulation and repairing injuried nerve rationally.

[Comparison and clinical significance between geometrical characteristics of tibial plateau between Uighur nationality and Han people].

OBJECTIVE: To compare the difference and clinical significance of geometrical characteristics of tibial plateau between Uighur nationality and Han people by computed tomography scan and three-dimensional reconstruction. METHODS: A total of 49 inpatients and outpatients were randomly selected (normal knee without any tibial involvement) and volunteers of Han people and 45 ones of the Uighur nationality at our hospital and cooperative hospitals. Then the subjects were divided into groups according to gender. The following linear geometric parameters of tibial plateau were measured: width of tibial plateau (WTP), width of medial tibial plateau (WMTP), sagittal length of medial tibial plateau (SLMTP), width of lateral tibial plateau (WLTP) and sagittal length of lateral tibial plateau (SLLTP). RESULTS: (1) Males were greater than females in linear parameters in the same group (P < 0.01); (2) the groups of Uighur nationality were greater than groups of Han people in linear parameters in the same gender (P < 0.05); (3) the gaps between WMTP and WLTP, SLMTP and SLLTP of Uighur nationality were all more approximate than those of Han people (P < 0.05). CONCLUSION: The geometrical characteristics of tibial plateau have some visible discrepancy between Uighur nationality and Chinese Han people. The prosthetic design concept and technology of total knee replacement targeting the Uighur nationality should take into consideration the discrepancy.
