Evaluation on effectiveness of neurolysis and nerve grafts surgery in treatment of early spontaneous posterior interosseous nerve entrapment / 吉林大学学报(医学版)

Objective To investigate the surgery method for early spontaneous posterior interosseous nerve entrapment,to observe the postoperative efficacy in treatment,to evaluate the surgical outcomes,and to provide a foundation for clinical choice of reasonable operation scheme.Methods 21 cases of early spontaneous posterior interosseous nerve entrapment received operation. 1 3 cases (1 8 arms) were treated by neurolysis, and 8 cases (8 arms )were treated by nerve grafts with small vessels wrapping operation;all the patients were followed up for 10 to 20 months;the finger extensor muscle strength and metacarpophalangeal joint activity were evaluated. Results The lesion extensor muscles were part of the denervation changes.Neurolysis muscle strength:14 arms were excellent(82.35%),2 arms were good,1 arm was fair,1 case was lost;extensor function:15 arms were excellent(88.24%),1 arm was good,1 arm was fair,1 case was lost.Nerve graft muscle strength:6 arms were excellent(75.00%),1 arm was good,1 arm was fair;extensor function:7 arms were excellent(87.50%),0 arm was good,1 arm was fair.Conclusion Neurolysis can have a good efficacy in treatment of early spontaneous posterior interosseous nerve entrapment without obvious degeneration.When the severe degeneration of entrapment nerve happens,a nerve graft surgical treatment is needed.

Effect of Treatment of Tibia and Fibula Fracture with internal Fixation of Fibula / 中华创伤骨科杂志

Objective To study the effect of internal fixation of fibula on treatment of tibia and fibula unstable fractures. Methods 50 cases with middle and lower 1/3 fractures of tibia and fibula were treated with internal fixation of fibula and close reduction and external stabilization of tibia. Fibula was stabilized with plate and screw or intramedullary nail. Results All the 50 cases of the fracture achieved clinic union, reduction was satisfactory, and the average time of clinical union was 5 months. The functions of the joint were normal. No skin necrosis or infection occurred. Conclusion Fixation of fibula is suitable for treatment of close fracture combined with local skin injury or open fractures of tibia and fibula and lower 1/3 comminuted fracture of tibia combined with fibula fracture.
