BACKGROUND:With the development of AO, the treatment of intercondylar humeral fractures with open reduction has been a trend. However, the methods of fixation become many. There is no conclusion of which method is optimal.
OBJECTIVE:To investigate the clinical effect of two kinds of different fixation methods (Y-type steel plate and double steel plate) for intercondylar humeral fractures via different surgical approaches.
METHODA retrospective analysis of clinical data of 86 cases of fresh intercondylar humeral fractures in the Department of Orthopedics, Sixth Affiliated Hospital, Xinjiang Medical University, between December 2003
and May 2014 were conducted in this study. According to the different fixation materials, patients were divided into two groupdouble steel group (n=44, including the surgical approach of ulna olecranon osteotomy which had 22 cases and the surgical approach of triceps V shaped severance which had 22 cases), Y-type steel group (n=42, including the surgical approach of ulna olecranon osteotomy which had 21 cases and the surgical approach of triceps V shaped severance which had 21 cases). The clinical curative effect and related complications of the two groups after operation were analyzed. During fol ow-up, modified Cassebaum elbow scoring system was used to evaluate the excellent and good rate of therapy.
RESULTS AND CONCLUSION:After fol owed up for 12-36 months, the total excellent and good rate of Y-type steel plate was 76%and the total excellent and good rate of double steel plate was 77%. There were no significant differences between the two groups (P>0.05). But interestingly, the surgical approach of ulna olecranon osteotomy was better than the surgical approach of triceps V shaped severance and the difference was statistical y significant (P<0.05). Above data suggested that Y-type steel plate and double steel plate were effective ways in the repair of intercondylar humeral fractures. However, for different surgical approaches, the surgical approach of ulna olecranon osteotomy was better than the surgical approach of triceps V shaped severance.

The aim of the present study was to establish a minimally invasive H reflex model in mice for the benefit of the research of clinical spinal cord injury and related diseases. Minimally invasive surgery was performed in hind limb of Kunming mouse under light anesthesia. The skin was incised at the point of one-third of the distance from greater trochanter to the base of the cauda. A pair of fine copper conductors were inserted into the shallow muscle using a syringe needle. After the needles were withdrawed, the retained conductors were ligated and fixed with the tissues surrounding the sciatic nerve as the first pair of stimulating electrodes. Another pair of conductors were inserted and fixed in medial malleolus close to the tibial nerve as the second stimulating electrodes. Copper conductor was inserted passing the skin above the proximal end of the metatarsal and fixed as the recording electrode. The reference electrode was placed at the walking pad in the base of the big toe using the same method. Electromyography (EMG) was used to record M and H waves in planta pedis muscles. The stimulus was a square wave with a width of 0.2 ms and frequency of 0.3 Hz. The latency time of the M and H waves which were induced from the two pairs of stimulating electrodes was recorded. Nerve conduction velocity (NCV) was then calculated from the distance between the cathodes of the stimulating electrodes and the latency time difference of M or H waves. The result showed the achievement ratios of H reflex induction were 92.73% and 81.82% in sciatic and tibial nerves, respectively. The latency time of H wave was about 7~10 ms. Motor nerve conduction velocity (MNCV) obtained was (25.84 ± 4.70) m/s (n = 35), while sensory nerve conduction velocity (SNCV) was (31.45 ± 7.30) m/s (n = 35). The method established in the present paper is simple to practice, does slight harm to the animal, and can produce waveforms with little interference. With these advantages, the method can be applied for the study of the latency of H reflex, and it is suitable for the researches which demands good physical condition of experimental animal during H reflex study. This model can also be applied to the detection of SNCV and MNCV.
