Objective:To investigate the clinical efficacy of integrated steel plate system combined with Kirschner wire internal fixation in the treatment of Lisfranc injury.Methods:Data of 30 cases with Lisfranc injury who were admitted from January 2010 to December 2018, including 22 males and 8 females were retrospectively analyzed. The age ranged from 22 to 58 years, with an average age of 44.5 years. All of them were closed injuries, including 8 cases involving metatarsal tarsal base fracture, and 2 cases with compression fracture of dice. Classification of Lisfranc joint injury: 6 cases of injury of the inner column alone, 10 cases of injury of the inner column and the middle column, 4 cases of injury of the middle column and the outer column, 10 cases of injury of the three columns. Cause of injury: traffic injury in 12 cases, machine injury in 10 cases, fall injury in 8 cases. The time from injury to operation was 2-7 d, with an average of 5 d. After the improvement of soft tissue conditions, all patients were treated with open reduction and internal fixation using integrated plate system combined with Kirschner wire, followed up by regular post-operative imaging examination, and the therapeutic effect was evaluated by the American Association of Foot and Ankle Surgery (AOFAS) midfoot score.Results:Thirty patients were followed up for 12-30 months (mean 24 months), during which no soft tissue complications such as wound infection and skin necrosis were observed. Average postoperative healing was observed at 12 weeks (10-16 weeks) for them who combined with fracture. At the latest follow-up, the AOFAS midfoot score was 65-95 points (mean 85 points). The midfoot function scores of the 30 patients were: excellent in 15 cases, good in 10, fair in 3, poor in 2. The excellent and good rate was 83.3% (25/30). One patient showed low toxicity and red skin 8 months after the operation. The integrated steel plate system was removed and the skin healed smoothly after the operation. One year after surgery, 10 patients requested removal of the internal fixation. None of the patients had the complication of plate, screw and Kirschner wire fracture. Two patients with three-column injury developed traumatic arthritis and walking pain 12 and 18 months after surgery, respectively, and then underwent metatarsal tarsal joint fusion. The postoperative pain disappeared.Conclusion:The integrated steel plate system combined with Kirschner wire internal fixation for the treatment of Lisfranc injury is simple, can avoid joint redislocation and articular cartilage reinjury, is a safe and effective method for the treatment of Lisfranc injury.

Objective: To investigate the value of the trigeminocervical response (TCR) for revealing bulbar
involvement in patients with spinal and bulbar muscular atrophy (SBMA). Methods: Thirty patients
with SBMA and 30 healthy male controls were included in this study. In all of the normal controls,
stimulation of the infraorbital nerve on one side produced bilateral short latency waves consisting
of a positive/negative wave, p19/n31, the mean latency of which was measured. The mean square
root of the ratio between the amplitude of p19/n31 and the mean rectifi ed surface electromyography
(EMG) activity preceding the stimulus, the A value, was estimated. The parameters of the TCR
were compared between the two groups. Results: Among the patients with SBMA, 21 (70.0%) had
delayed latencies of p19/n31 (P < 0.01) and all (100%) had reduced A values (P < 0.01) relative to
the normal controls.
Conclusions: All parameters of the TCR were signifi cantly different between the patients with SBMA
and the normal controls. T

OBJECTIVETo explore effectiveness and safety of segmental anterior cervical decompression in treating multi-level cervical myelopathy.
METHODSTwenty-four patients with four levels of cervical myelopathy were treated with segmental anterior cervical decompression (reservation of middle vertebrae, bone graft and plate-screws fixation). Among patients, there were 15 males and 9 females aged from 47 to 75 (averaged 57.9) years old. Preoperative, postoperative at 1 week and the latest following-up AP and lateral X-rays were used to observe bone union, displacement of implant, adjacent segment degeneration, changes of Cobb angle of fusion segment. JOA scoring were applied for evaluate recovery of nerve function.
RESULTSAll operations were completed successfully, 2 cases ocurred hoarseness, and improved after treated symptomatically. Nineteen patients were followed up from 3.1 to 5.3 years with an average of 3.9 years. Bone union time ranged from 3 to 7 (averaged 4.5) months. No screw loosening and displacement occurred. Nine patients occurred titanium mesh subsidence in different degrees, and 4 of them subside >3 mm; four patients ocurred adjacent segment degeneration. Postoperative Cobb angle of fusion segment at 1 week (10.40±2.94)° was improved from preoperative (5.76±4.16)°, but decreased at the latest follow-up (8.57±2.82)°, and had significant meaning compared with preoperative (P<0.01). JOA score at the latest follow-up (14.6±1.1) was higher than that of before operation (8.2±1.9), and had siginificant differences (P<0.01).
CONCLUSIONSegmental anterior cervical decompression for the treatment of multilevel cervical myelopathy has a high clinical operability, and plays an important role in recovering cervical curvature and nerve function based on completely decompression.
