Objective To summarize the clinical effects of the treatments of skin necrosis with nickelclad exposure after calcaneal fractures surgery by lateral leg flap. Methods Thirty-five cases of postoperative skin necrosis and nickelclad exposure of calcaneal fractures were repaired by lateral leg flap. Results The flaps was applied successly in 35 cases and followed up from 6 months to 5 years. All cases'wound was primary healing, the texture of the flaps were fine, and the function of the feet was not affected. Conclusion The lateral leg flap is an optimal method for the repair of postoperative skin necrosis and nickelclad expo-sure of calcaneal fractures, which can get satisfactory clinical effects.

Objective To observe the multi-segmental cervical spondylotic myelopathy with simple anterior or posterior joint pre-and post-operative prognosis of spinal cord function improved and the status, explore co-operation after the clinical efficacy and complications. Methods The clinical data of 298 cases of multi-segmental cervical spondylotic myelopathy with anterior or posterior of the simple pre-and post-joint surgery from January 2001 to January 2008 were retrospectively analyzed. The clinical efficacy, titanium anterior cervical decompression and fusion surgery net implanted titanium plate fixation 121 cases, posterior open-door laminoplasty 112 cases, 65 cases of combined surgery before and after. JOA score line of spinal cord function and somatosensory evoked potential, as compared 3 groups after surgical efficacy. Results All patients were followed-up 1- 7 years, averaged (4.7±1.4) years. The anterior cervical decompression and fusion surgery titanium mesh implanted titanium plate fixation to improve the rate was 78.1%, excellent and good rate was 72.7%(88/121). Posterior open-door laminoplasty to improve the rate was 70.6%, excellent and good rate was 66.1% (74/112), there was statistically significant between them (P < 0.05). After anterior surgery, improving rate was 86.7%, excellent and good rate was 83.1% (54/65). Anterior and posterior combined surgery before and after comparison was significant (P < 0.05), regardless of near-term results, long-term effects were better than that of anterior or posterior surgery. Conclusions The spinal cord in the treatment of multi-segmental operation of cervical spondylosis after anterior surgery is obviously superior to the efficacy of anterior or posterior surgery alone. Spinal stability anterior, posterior, after a joint operation before the lower one by one.
