Double plate technique and tendon fixation of long head of biceps brachii in treating Neer 3 to 4 partial fractures of proximal humerus / 中国骨伤

OBJECTIVE@#To explore clinical effect of double plate technique in treating Neer 3 to 4 partial fractures of proximal humerus.@*METHODS@#From May 2018 to December 2020, 38 patients with proximal humeral classified to Neer 3 to 4 partial fractures were treated with double plate technique and long head tendon fixation of biceps brachii, including 23 males and 15 females, aged from 41 to 89 years old with an average of (67.00 ± 9.76) years old;23 patients classified to Neer 3 fracture, 15 classified to Neer 4 fracture;the time from injury to operation ranged from 5 to 12 days with an average of (8.00±2.86) days. Degree of pain was evaluated by numerical rating scale(NRS) on the third day after operation; change of height of humeral head and angle of humeral neck stem were measured and compared between 2 days and 1 year after operation. Neer score was used to evaluate recovery of shoulder joint after operation at 1 year after operation.@*RESULTS@#All 38 patients were followed up for 12 to 19 months with an average of (14.00±1.59) months. NRS score at 3 days after operation was (1.95±0.73) points. Fracture healing time ranged from 2.2 to 3.2 months with an average of(2.60±0.27) months. There were no significant difference in the height of humeral head and angle of humeral neck trunk between two days and 1 year after operation(P>0.05). Four Neer 4 fracture patients occurred absorption of greater tubercle of humerus and partial cystic change of humeral head, but the activity function of shoulder joint was good. Postoperative Neer score at 1 year was 89.50±5.19, and 20 patients got excellent results, 16 good, and 2 moderate.@*CONCLUSION@#Double plate technique and long head tendon fixation of biceps brachii were used to treat Neer 3 to 4 fractures of proximal humerus has good clinical effect, and postoperative pain was mild, without special instruments.

Association between SCN1A rs3812718 polymorphism and generalized epilepsy with febrile seizures plus / 中国当代儿科杂志

<p><b>OBJECTIVE</b>To investigate the association between SCN1A rs3812718 polymorphism and generalized epilepsy with febrile seizures plus (GEFS+), and to provide potential molecular targets for the diagnosis and treatment of GEFS+.</p><p><b>METHODS</b>The iPLEX technique in the MassARRAY system was used to determine SCN1A rs3812718 polymorphism, genotype frequency, and allele frequency in 50 patients with GEFS+ and 50 healthy controls.</p><p><b>RESULTS</b>As for the frequencies of CC, CT, and TT genotypes in SCN1A rs3812718, there was a significant difference in the frequency of TT genotype between the GEFS+ group and the control group (P<0.05). There was also a significant difference in the frequency of T allele between the two groups (P<0.05). Compared with those carrying CC genotype or C allele, the individuals with CT genotype , TT genotype or T allele had a higher risk of developing GEFS+ (CT/CC: OR=4.05, 95%CI: 1.04-15.69; TT/CC: OR=30.60, 95%CI: 6.46-144.85; T/C: OR=4.64, 95%CI: 2.54-8.48).</p><p><b>CONCLUSIONS</b>SCN1A rs3812718 polymorphism is a risk factor for GEFS+, and the population carrying T allele may have an increased risk of GEFS.</p>

Reconstructing coracoclavicular ligament in treating Rockwood - III Acromioclavicular dislocation by palmaris longus muscle with polyester suture / 中国骨伤

<p><b>OBJECTIVE</b>To explore therapeutic effects of reconstructing coracoclavicular ligament for the treatment of Rockwood-III Acromioclavicular dislocation by palmaris longus muscle with polyester suture.</p><p><b>METHODS</b>From August 2011 to November 2013,37 cases with Rockwood-III acromioclavicular dislocation were treated with reconstructing coracoclavicular ligament by palmaris longus muscle with polyester suture. Among patients, 24 were males and 13 were females, ranging the age from 19 to 46 years old, with an average of 32 years old. There were 11 cases on the left side and 26 cases on the right side. Twenty-nine cases were fresh dislocation and 8 cases were old dislocation. Blood loss, operative time were observed, and Karlsson evaltae standard were applied for assessing postoperative recovery of shoulder joint function.</p><p><b>RESULTS</b>All patients were followed up from 2.5 to 5 months with an average of 3.5 months. Operative time ranged from 52 to 98 (meaned 72) min, blood loss ranged from 50 to 180 (meaned 75) ml. All operative incision were healed at the satge I . According to Karlsson standard, 32 cases obtained excellent results and 5 cases were moderate.</p><p><b>CONCLUSION</b>For Rockwood-III acromioclavicular dislocation,reconstructing coracoclavicular ligament by palmaris longus muscle with polyester suture has advantages of simple operation, and rapid recovery of shoulder joint function.</p>

Treatment of humeral supracondylar fracture in children with internal fixation using Kirschner wires and biodegradable tension band through double small incisions / 中国骨伤

<p><b>OBJECTIVE</b>To study therapeutic effects of internal fixation with Kirschner wires and biodegradable tension band through double small incisions for the treatment of humeral supracondylar fracture in children.</p><p><b>METHODS</b>From 2006 to 2010,82 children with humeral supracondylar fractures were treated with internal fixation using crossed Kirschner wires combined with biodegradable tension bands. Among the patients, 53 patients were male and 29 patients were female, ranging from 5 to 12,with an mean of 7 years old. The elbow joint function and Carrying angle were observed before and after treatment. The Flynn criteria was used to evaluate therapeutic effects.</p><p><b>RESULTS</b>All the patients were followed up, and the duration was six months. The average limitation angle of elbow joint was (2.8 +/- 3.7) degrees,and the Carrying angle was (12.7 +/- 2.2) degrees. According to Flynn clinical evaluation, 80 patients got an excellent result, 2 good.</p><p><b>CONCLUSION</b>Treatment of child humeral supracondylar fracture with internal fixation using Kirschner wires and biodegradable tension bands through double small incisions is believed to be a good method, which has advantages of minimal trauma, reliable fixation, early exercises and rapid recovery.</p>
