Methods： This is a retrospective study of 26 scaphoid nonunion cases treated by this technique between 2004 and 2009. The mean age was 38 years. Nonunion was of types IIA and IIB according to the Alnot＇s classification and only one case showed a proximal pole necrosis （type IV）. The fixation was ensured by K-wire. The mean immobilization period was 9 weeks. Results： At mean 19 months follow-up, the bone union rate was 88.5%. Failure was noted in three cases. No significant complications secondary to this technique were observed. The mobility in extension and flexion had an average recovery of 18°. Nineteen patients （73%） were free of pain, and the others had occasional pain Conclusions： It is a meticulous surgical technique that provides better union rates than those of conventional scaphoid graft. This technique is first adopted in cases of failure of conventional grafts in the treatment of scaphoid nonunion but the encouraging results suggest expanding indications to primitive nonunion.展开更多

Here we reported a case of compartment syndrome in the upper limb following an adder bite in the thenar eminence. Elevated compartment pressure was documented and immediate surgical fasciotomy was practiced. The patient achieved complete recovery with a good functional result. We discussed the controversies on fasciotomy and non-invasive measures in such a situation, and recommended intracompartmental pressure monitoring during the management of compartment syndrome following adder bites.展开更多
