They were 11 boys and 5 girls, aged from 8 to 14 years (average, 11.0 years). Their fractures were located at proximal humerus in 4 cases, at distal femur in 3 cases, at proximal tibia in 3 cases and at distal tibia in 6 cases. According to the Salter-Harris classification, 6 cases were type Ⅱ, 5 cases type Ⅲ and 5 cases type Ⅳ. The time from injury to surgery ranged from 3 to 8 days, averaging 5.3 days. The fracture healing time, postoperative complications (infection and implant failure) and postoperative functional recovery were recorded. \u0000 \u0000 \u0000Results \u0000This cohort obtained follow-up from 12 to 18 months (average, 13 months). All the children obtained bony union after 2 to 5 months (average, 2.4 months).

They were divided into 3 groups according to the internal fixation method they had used. In the single incision locking plate group (group A) of 21 cases, there were 13 males and 8 females with an age of 50.6 years±12.9 years. In the double-incision locking plate combined with reconstruction plate group (group B) of 18 cases, there were 11 males and 7 females with an age of 53.5 years±13.0 years. In the single incision locking plate combined with reconstruction plate group(group C) of 19 cases, there were 10 males and 9 females with an age of 48.1 years±12.2 years. The 3 groups were compared in terms of operation time, intraoperative blood loss, intraoperative C-arm fluoroscopy, fracture healing time, incidence of postoperative complications, range of motion of the knee and knee functional recovery. \u0000 \u0000 \u0000Results \u0000The 3 groups were compatible because there were no significant differences between them in their preoperative general data (P>0.05). There were no significant differences between groups in the frequency of C-arm fluoroscopy, follow-up time, or incidence of postoperative complications (P>0.05). The operation time in groups A and C (96.7 min±16.4 min and 101.9 min±16.5 min) and intraoperative blood loss for groups A and C (237.8 mL±47.5 mL and 253.6 mL±46.6 mL) were significantly less than in group B (114.9 min±20.1 min and 290.1 mL±60.9 mL) (P<0.05); the fracture healing time for groups B and C (6.9 months±1.6 months and 6.6 months±1.7 months) was significantly shorter than for group A (8.4 months±1.9 months) (P<0.05); the ranges of knee motion 12 months after operation in groups B and C (91.7°±16.7° and 90.9°±14.4°) were significantly larger than that in group A (78.8°±14.4°) (P<0.05); the excellent and good rates of knee function 12 months after operation in groups B and C [77.8% (14/18) and 73.7% (14/19)] were significantly higher than that in group A [57.1%(12/21)] (P<0.05). \u0000 \u0000 \u0000Conclusion \u0000In the treatment of distal femoral fractures of Muller types C2 and C3, application of lateral locking plate and additional anterior locking reconstruction plate via the anterolateral incision at the distal femur can achieve rigid fixation without much damage to the surrounding soft tissues and lead to fine functional recovery of the knee joint because it has the advantages of single incision locking plate and double incision medial and lateral locking plates. \u0000 \u0000 \u0000Key words: \u0000Femoral fractures; Fracture fixation, internal; Bone plates; Surgical approach","PeriodicalId":10145,"journal":{"name":"Chinese Journal of Orthopaedic Trauma","volume":"22 1","pages":"238-242"},"PeriodicalIF":0.0,"publicationDate":"2020-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45643673","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They were 4 males and 3 females, aged from 31 to 87 years (average, 55.6 years). Their fractures happened on the left side in 3 patients and on the right side in 4. By the Seinsheimer classification, there were 3 cases of type Ⅱ, 2 cases of type Ⅲ and 2 cases of type Ⅴ. The time from injury to surgery ranged from 9 to 44 hours, averaging 26 hours. All patients were treated by intramedullary nailing after natural reduction at prone position. Their preoperative preparation time, time required for reduction, total operation time, fluoroscopic frequency for guide pin insertion, fluoroscopic frequency for reduction, reduction quality, complications and curative effect were recorded. \u0000 \u0000 \u0000Results \u0000Closed reduction and intramedullary nail fixation were completed uneventfully in all the 7 cases. Their preoperative preparation time averaged 29.4 min (from 21 to 42 min), reduction time 6.3 min (from 3 to 10 min), and total operation time 157 min (from 82 to 275 min). Their fluoroscopic frequency averaged 37 times (from 14 to 96 times) for guide pin insertion and 23 times (from 10 to 49 times) for reduction, totaling 244 times (from 121 to 360 times). According to the modified Baumgaetner criteria, the fracture reduction was evaluated as excellent in 6 cases and as fair in one. The 7 patients were followed up for 12 to 34 months (mean, 20.1 months). A drill broke at the interlocking nail hole during operation in one patient, deep venous thrombosis occurred at a lower extremity in another during hospitalization, and fracture nonunion was observed after operation in another, but no complications related to the prone position were observed. The curative effect evaluated by Harris hip score at the last follow-up was excellent in 4 cases, as good in 2 cases and as fair in one. \u0000 \u0000 \u0000Conclusion \u0000In the treatment of femoral subtrochanteric fractures with intramedullary nailing, the prone position benefits natural reduction and maintenance of reduction and allows convenient fluoroscopy and nail placement during operation, especially for obese patients. \u0000 \u0000 \u0000Key words: \u0000Hip fractures; Fracture fixation, intramedullary; Bone nails; Reduction; Prone position","PeriodicalId":10145,"journal":{"name":"Chinese Journal of Orthopaedic Trauma","volume":"22 1","pages":"218-223"},"PeriodicalIF":0.0,"publicationDate":"2020-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48715963","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Of them, 27 ones, 15 males and 12 females with an age of 57.5 years±16.2 years (group A), were fixated with Gamma 3 nails and hollow compression screws, including 14 cases of AO type of 31-A2.2 and 13 cases of AO type of 31-A2.3. The other 33 patients, 18 males and 15 females with an age of 59.3 years±15.1 years (group B), were fixated with Gamma 3 nails alone, including 17 cases of AO type of 31-A2.2 and 16 cases of AO type of 31-A2.3.

They were 9 men and 14 women with an average age of 85.3 years (range, from 80 to 91 years).

The antibacterial property of an iodine-coated titanium plate is superior to that of a titanium plate without iodine coating. \u0000 \u0000 \u0000Key words: \u0000Iodine; Potassium iodide; Titanium; Bone plates; Infection","PeriodicalId":10145,"journal":{"name":"Chinese Journal of Orthopaedic Trauma","volume":"22 1","pages":"249-254"},"PeriodicalIF":0.0,"publicationDate":"2020-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46413177","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
