ABSTRACT
Objective To investigate the clinical features of multiple ligament injuries of the knee joint, and evaluate the clinical efficacy of one-stage repair and reconstruction under an arthroscope of multiple ligament injured knee joint. Methods The clinical data were analyzed retrospectively of 22 patients receiving treatment and follow-up for multiple ligament injuries of the knee joint from March 2015 to June 2017 in the Henan Orthopedic Hospital. 13 males and 9 females aged from 24 to 64 years; and left knee injury occurred in 7 cases, right knee in 5 cases, all injuries were close with knee subluxation or dislocation. Imaging, clinical and arthroscopical examination showed anterior and posterior cruciate ligament ruptures in all the patients. The time from injury to operation was from 4 to 16 days, all the patients were treated by single tunnel and single beam reconstruction of anterior and posterior cruciate ligament under an arthroscope, limited incision and reconstruction of PMC (posterior medial complex) and PLC (posterior lateral complex); and the concurrent injuries were treated at that same time. Postoperative X-Ray and MRI were performed to determine the healing of bone tunnel, internal fixation, remodeling of reconstructed tendon and tendon healing. The knee function was assessed on the basis of the range-of-motion of the knee, IKDC score and Lysholm Knee Function score. Results All the patients were followed up from 6 to 14 months with an average of (11.0±1.5) months. The torn inner and outer meniscus and fracture were all healed and the deep venous thrombus was dissolved. Last follow up found varus and valgus stress test was normal or close to normal in 22 patients by Lachman test, anterior and posterior drawer tests were negative, and the tibial shift distance forward or backward was smaller than 5mm. The patients had no subjective symptoms. X-Ray and MRI showed that the tibial femoral tunnel had healed, and the position of internal fixation had no change, and the ligament had been reconstructed and the tendon had healed. In 2 cases, one year later, sensory and motor recovery was observed after common peroneal nerve injury. Range of motion of the knee joint, and Lysholm and IKDC scores were significantly superior at the last following up to at the preoperation (P<0.01); and IKDC comprehensive assessment revealed a normal result (A) in 4 cases, close to normal (B) in 16, abnormal (C) in 2, whereas they are significantly abnormal (D) at admission. Conclusion One-stage arthroscopical repair and reconstruction for multiple ligament injuries of the knee can obviously stabilize the knee joint, improve the knee joint function early, prevent postoperative complications, shorten the hospitalization time, reduce the cost, improve the quality of life, and have the advantages of safety, reliability and less trauma, and the clinical efficacy is satisfactory.

ABSTRACT
<p><b>OBJECTIVE</b>To explore the clinical efficacy of double-plate fixation for the treatment of old tibial plateau fractures with Schatzker type IV through anterior midline and posteromedial approaches.</p><p><b>METHODS</b>From July 2013 to July 2015, 15 patients with old tibial plateau fractures were treated with internal fixation using locking reconstructive plate for the posteromedial fragment and anatomical locking plate for anteromedial fragment through antero midline and posteromedial approaches. There were 9 males and 6 females, with an average age of 49.2 years old (ranged, 21 to 61 years old). Eight patients had injured in the left side and 7 in the right side. According to Schatzker classification, all patients were type IV. The mean interval from injury to operation was 26.5 days (ranged, 21 to 65 days). The main clinical symptoms before operation were knee joint swelling, pain, deformity and limitation of motion. The X-ray and CT confirmed the fracture type. The indexes such as tibial plateau tibial shaft angle (TPA), femoral tibial angle (FTA) and posterior slope angle (PSA) were compared between immediate postoperation and final follow-up using postoperative X-ray film. The knee functions were evaluated using the HSS (Hospital for Special Surgery) knee score system.</p><p><b>RESULTS</b>Two patients had incision complications which healed by correct treatment, 1 patient had traumatic arthritis. All patients were followed up for mean 16.6 months (ranged, 13 to 24 months). No infections, deep venous thrombosis, implant loosening and breakage, fragment displacement, plateau surface collapse and bone nonunion found. The bone union time ranged from 3 to 8 months (mean 6.07 months) after operation. The average immediate postoperative value of TPA, FTA and PSA were(86.81±1.67)°, (168.00±3.29)° and(10.20±1.47)° respectively; and(86.47±1.67)°, (168.53±3.03)° and (10.54±1.21)° respectively at the final follow-up evaluation, showing no statistical differences(>0.05). According to the HSS score system, 26.33±3.86 in pain, 20.00±1.79 in function, 16.00±1.55 in range of motion, 8.67±0.94 in muscle strength, 8.53±1.67 in flexion deformity, 9.33±0.94 in joint stability, and the total mean score was 88.86±8.92. The outcomes were excellent in 10 cases, good in 4, and fair in 1.</p><p><b>CONCLUSIONS</b>Double-plate fixation via combined anterior midline and posteromedial approaches is an ideal surgical method for old tibial plateau fractures with Schatzker IV type, showing satisfactory exposure, reliable reduction and fixation, and benefiting for early functional exercise.

ABSTRACT
Objective To observe the therapeutic effect of bone cement injectable pedicle screw system combined with intervertebral fusion for lumbar spondylolysis and osteoporosis. Methods The clinical data were analyzed retrospectively of 21 patients with lumbar spondylolysis and osteoporosis who received treatment of bone cement injectable pedicle screw system and interv ertebral fusion from Aug. 2013 to Nov. 2015. The 21 patients (9 males and 12 females) aged from 60 to 80 years (mean 64 years old); 6 of them presented degenerative spondylolysis, 15 with isthmic spondylolisthesis; 2 cases had I degree slippage, 13 had II degree slippage, 6 had III degree slippage, and all the cases were unisegmental slippage including 9 cases in L4 and 12 cases in L5. Bone mineral density of lumbar vertebrae (L2-L5) was measured with dual-energy X-ray absorptiometry, and T values conforming to the diagnostic criteria of osteoporosis were less than or equal to -2.5; All patients were operated with whole lamina resection for decompression, bone cement injectable pedicle screws system implantation, propped open reduction and fixation intervertebral fusion. The clinical outcomes were determined by the radiographic evaluation including intervertebral height, height of intervertebral foramen, slip distance, slip rate and slip angle, and Oswestry disability index (ODI) on preoperative, 3 months after operation and the end of the time, and the interbody fusion were followed up. Results Cerebrospinal fluid leakage of incision was observed in two cases after operation, compression and dressing to incision, Trendelenburg position, dehydration and other treatments were taken, and the stitches of incisions were taken out on schedule. Slips in the 21 patients were reset to different extent, and lumbar physiological curvatures were recovered. The intervertebral height and height of intervertebral foramen were obviously higher 3 months after operation than that before operation (P0.05). Based on the ODI score, the excellent/fine rate was 90.6% and 92.5% for 3 months after operation and the last follow-up, respectively. During the period of following up, no loss of the correction degrees, no loosening of the screws, and 19 cases were noted bony fusion with the fusion success rate of 90.5%. Conclusion The treatment effect of bone cement injectable pedicle screw system and intervertebral fusion for lumbar spondylolysis and osteoporosis is satisfied.
ABSTRACT
Exercise-induced fatigue is a comprehensive response to a variety of physiological and biochemical changes in the body, and can affect people’s quality of life to different extents. If no timely recovery after occurrence of fatigue, accumulated gradually, it can lead to “burnout”, a “overtraining syndrome”, “chronic fatigue syndrome”, etc., which will cause endocrine disturbance, immune suppression, even physical illness. Exercise-induced fatigue becomes an important factor endangering human health. In recent years, many experts and scholars at home and abroad are committed to the research of exercise-induced fatigue, and have put forward a variety of hypothesis to explain the cause of exercise-induced fatigue. They expect to find out the methods for preventing and eliminating exercise-induced fatigue. This article discusses mainly the pathogenesis, model building, elimination/ relief, etc. of exercise-induced fatigue to point out the research achievements of exercise-induced fatigue and its existing problems.
ABSTRACT
Objective To observe the treatment effect of internal fixation with absorbable suture anchors for calcaneal apophysitis (Sever's disease). Methods The clinical data of 34 Sever's disease patients having received internal fixation with absorbable suture anchors from January 2010 to August 2012 were analyzed retrospectively. Of the 34 patients, 28 were male and 6 were female, aged from 11 to 30 years old (mean 19 years old); 20 with unilateral lesions, 14 with bilateral lesions; 32 suffered inflammatory edema, and 2 with epiphyseal avulsion. All of the patients were diagnosed as suffering from Sever's disease by X-ray combined with clinical symptoms. The sclerotic bone was chiseled off, the attachment site of Achilles tendon was fixed with auxiliary sutures of anchors and then fixed to the bone surface. Different rehabilitation programs were adapted in different periods after operation. The operation time, the site of anchorage and perioperative complications were analyzed, and the therapeutic effects were evaluated by Arner-Lindholm standard. Results All patients were followed up for 2-24 months (mean 9 months). The average operation time for one side was 40.5 minutes. No iatrogenic injury to nerve, vascular or tendon occurred during surgical procedure. No wound infection or foreign-body reaction was found after operation. The therapeutic effects evaluated by Arner-Lindholm standard were excellent in 29 cases, good in 4 and bad in 1 case. Conclusion Absorbable suture anchoring fixation is a reasonable and effective method for the treatment of Sever's disease, and it allows early exercise training for recovery of ankle function. The postoperative functional recovery is found to be satisfactory.
ABSTRACT
Objective To investigate the anti-fatigue effect of percutaneous stimulation of the hepatic region with the mid-frequency pulse current in different diadynamic cycles in exercise-induced fatigued soldiers. Methods One hundred twenty healthy PLA recruits who did not have physical exercise were randomly divided into four groups with thirty ones in each: control, stimulation group A, stimulation group B, and stimulation group C. All the subjects of four groups were ordered intensive training (exercise from Monday to Saturday, with rest on Sunday) for five weeks to establish the exercise-induced fatigue model. Each day after the exercise, the recruits of stimulation groups A, B, and C were treated immediately with mid-frequency (1204Hz, current intensity ≤80mA) stimulation to the hepatic region with diadynamic cycles of 0.5, 1, and 2 seconds, respectively. No pulse current stimulation was given in the control group. Venous blood was collected before breakfast on Sundays to measure the fasting plasma glucose (FPG) and blood lactate (LAC) contents, and liver function was determined by determination of alanine aminotransferase (ALT), aspartate aminotransferase (AST), and lactate dehydrogenase (LDH). The 3000-m running performance of the recruits in each group was recorded on the same day. Results There was no significant difference between the four groups in terms of the FPG level at the end of the first week (P>0.05). At the end of the third and fifth weeks, the FPG level was significantly higher in the three stimulation groups than in the control group (P0.05). At the end of the first, third, and fifth weeks, the ALT, AST, LDH, and LAC levels were significantly lower in every stimulation group than in the control group (P0.05). At the end of the first week, there was no significant difference in 3000-m running performance (P>0.05) between the 4 groups. At the end of the third and fifth weeks, the 3000-m running performance was significantly better in every stimulation group than in the control group (P0.05). Conclusions Percutaneous stimulation of the hepatic region with mid-frequency pulse current in different diadynamic cycles can reduce liver injury due to exercise-induced fatigue, promote the generation of energy source in vivo, accelerate the elimination of lactate, improve the exercise endurance and exert a role in relieving exercise-induced fatigue, and the efficacy of the mid-frequency pulse current with 1204 Hz and diadynamic cycles of 1 second is the best.
