ObjectiveTo introduce the surgery method to reset and fix tibial plateau fracture without opening joint capsule, and evaluate the safety and effectiveness of this method. MethodsBetween July 2011 and July 2013, 51 patients with tibial plateau fracture accorded with the inclusion criteria were included. All of 51 patients, 17 cases underwent open reduction and internal fixation without opening joint capsule in trial group, and 34 cases underwent traditional surgery method in control group. There was no significant difference in gender, age, cause of injury, time from injury to admission, side of injury, and types of fracture between 2 groups (P>0.05). The operation time, intraoperative blood loss, incision length, incision heal ing, and fracture healing were compared between 2 groups. The tibial-femoral angle and collapse of joint surface were measured on X-ray film. At last follow-up, joint function was evaluated with Hospital for Special Surgery (HSS) knee function scale. ResultsThe intraoperative blood loss in trial group was significantly less than that in control group (P<0.05). The incision length in trial group was significantly shorter than that in control group (P<0.05). Difference was not significant in operation time and the rate of incision heal ing between 2 groups (P>0.05). The patients were followed up 12-30 months (mean, 20.4 months) in trial group and 12-31 months (mean, 18.2 months) in control group. X-ray films indicated that all cases in 2 groups obtained fracture heal ing; there was no significant difference in the fracture healing time between 2 groups (t=1.382, P=0.173). On X-ray films, difference was not significant in tibial-femoral angle and collapse of joint surface between 2 groups (P>0.05). HSS score of the knee in trial group was significantly higher than that of control group (t=3.161, P=0.003). ConclusionIt can reduce the intraoperative blood loss and shorten the incision length to use open reduction and internal fixation without opening joint capsule for tibial plateau fracture. Traction of joint capsule is helpful in the reduction and good recovery of joint surface collapse. In addition, the surgery without opening joint capsule can avoid joint stiffness and obtain better joint function.
Objective To summarize the preliminary effectiveness of I.T.S. locking plate for intra-articular calcaneal fractures. Methods Between July 2010 and July 2011, 18 cases of intra-articular calcaneal fractures were treated. There were 10 males and 8 females with an average age of 46 years (range, 25-64 years). According to Sanders classification system, there were 3 cases of type II, 9 cases of type III, and 6 cases of type IV. The disease duration was 5-11 days (mean, 6 days). Open reduction and internal fixation with I.T.S. locking plate were performed via an L-shaped lateral extending incision. Results Superficial infection occurred in 1 case, and was cured after dressing changing; healing of incision by first intention was obtained in the other cases. Sixteen cases were followed up 14 months on average (range, 12-18 months). X-ray films demonstrated the bone union in all cases with an average union time of 12 weeks (range, 10-14 weeks). No implant failure or irritation of peroneal tendon occurred during follow-up. X-ray films showed subtalar post-traumatic arthritis with mild pain in 1 case at 11 months after operation, which was relieved by conservative treatment. At last follow-up, the Bouml;hler angle was improved from (12.9 ± 3.2)° preoperatively to (33.8 ± 4.0)° postoperatively, showing significant difference (t=22.78, P=0.00); the Gissane angle was improved from (83.6 ± 6.4)° preoperatively to (119.9 ± 8.5)° postoperatively, showing significant difference (t=17.02, P=0.00). The visual analogue scale (VAS) score was 1.3 ± 1.2, and the ankle and hindfoot scale of American Orthopaedic Foot and Ankle Society (AOFAS) was 80.3 ± 7.9 at last follow-up. Conclusion Treatment of intra-articular calcaneal fracture with I.T.S. locking plate can obtain a stable fixation, which is a safe and effective method.
Objective To compare the cl inical results of two plating osteosynthesis techniques, open reduction and plating ostosynthesis (ORPO) and minimal invasive plating osteosynthesis (MIPO), in surgical treatment of mid-distal humeralshaft fractures. Methods From March 2004 to October 2006, 40 cases of closed unilateral mid-distal humeral shaft fractures were surgically treated with MIPO or ORPO. In the MIPO treated group (n=19), there were 14 males and 5 females, with a mean age of 39.05 years. Fractures involved in middle humeral shaft in 10 cases and distal fragment in 9 cases. According to OTA classification, there were 3 cases of type A, 13 cases of type B and 3 cases of type C. Four cases compl icated by radial nerve palsies. In the ORPO treated group (n=21), there were 13 males and 8 females with a mean age of 39.05 years, including 14 cases of type A and 7 cases of type B fractures according to OTA classification. The fractures involved in middle humeral shaft in 13 cases and distal fragment in 8 cases. Five cases compl icated by radial nerve palsies. The time from injury to operation in both groups were 2 to 14 days. For patients in the MIPO group, fractures were closely reduced and fixated with an anterior placed plate inserted through two small incisions made at the anterior side of arm, away from fracture sites. The radial nerves were not exposed. For patients in the ORPO group, fractures were exposed, reduced, and fixated with an anterolateral or a posterior positioned plate after careful dissection and protection of radial nerve through an anterolateral or a posterior approach. The operation time, the occurrence of iatrogenic radial nerve palsy and the bone heal ing time were recorded. The functions of the affected shouldersand elbows were evaluated with UCLA end-result score and Mayo elbow perform index (MEPI), respectively. Results All the wounds in both groups healed primarily. There was no iatrogenic radial nerve palsies in the MIPO group after surgery; however, 5 cases of transient iatrogenic radial nerve palsies were identified in the ORPO group after surgery, and the function of radial nerve recovered in these cases at the last follow-up. Eighteen cases were followed up 14-44 months (mean 25.44 months) in MIPO group, and 19 cases were followed up 13-48 months (mean 32.11 months) in ORPO group. The mean bone heal ing time was 17.06 (12-32) weeks in MIPO group and 16.11 (8-58) weeks in ORPO group, showing no significant difference between two groups (P gt; 0.05). There was no nonunion and hardware failure in both groups. The mean forward flexion of the shoulder was 166.94° (150-170°) in MIPO group and 164.74° (130-170°) in ORPO group. The mean UCLA shoulder score was 34.78 (33-35) points in MIPO group and 34.42 (30-35) points in ORPO group. The mean range of motion of the elbow in MIPO and ORPO groups was 133.33° (120-140°) and 136.7° (120-140°), respectively. The MEPI in these two groups was 99.44 (90-100) and 99.74 (95-100) points, respectively. There was no statistically significant difference between two groups in all indexes mentioned above. Conclusion The good results could be obtained when ORPO and MIPO technique are appl ied to treat mid-distal humeral shaft fractures. MIPO technique has advantages to not expose the radial nerve and to decrease the occurrence of iatrogenic radial nerve palsies.
Objective To evaluate the operative procedure and the cl inical effectiveness of open reduction and internal fixation in the treatment of posterior malleolus fractures. Methods Between June 2005 and December 2008, 46 patients with posterior malleolus fractures were treated with open reduction and internal fixation and followed up. There were 29 males and 17 females with an average age of 47.7 years (range, 19-76 years). Fractures were caused by sprain in 17 cases, by fallingin 15 cases, by traffic accident in 12 cases, and by other reasons in 2 cases. The locations were left ankle in 25 cases and right ankle in 21 cases. There were 6 simple posterior malleolus fractures, 13 lateral and posterior malleolus fractures, and 22 trimalleolar fractures, and 5 lateral and posterior malleolus fractures accompanying by injury of deltoid l igament of ankle. According to Lauge- Hansen classification system, 13 cases and 9 cases were rated as supination-external rotation type III and type IV respectively, and 18 cases as pronation-external rotation type IV. According to Naoki’s classification of posterior malleolus fractures, there were 29 cases of posterolateral-obl ique type, 11 cases of medial-extension type, and 6 cases of small-shell type. Seven patients underwent emergency operation and 39 patients underwent selective operation. Results Two patients developed superficial infection, which was cured after dressing change, and the other incisions healed by first intention. Forty-six patients were followed up 37 months on average (range, 18-63 months). All fractures healed after 3 to 6 months (mean, 4.3 months). One patient developed lateral suralcutaneous nerve injury, and 9 patients had mild weight-bearing pain or discomfort. The results of American Orthopaedic Foot and Ankle Society (AOFAS) ankle and hindfoot score were excellent in 17 cases, good in 21 cases, and fair in 8 cases with an excellent and good rate of 83%. The mean visual analogue scale (VAS) score was 1.9 (range, 0-5). Conclusion The anatomic reduction and internal fixation can achieve the satisfactory results in the treatment of posterior malleolus fractures. The best treatment and fixation methods should be chosen based on different types of posterior malleolus fractures.
Objective To evaluate the effects of T-shaped plate internal fixation in treatment of intra-articular fracture of distal radius. Methods From January 2005 to March 2008, 52 cases of intra-articular fracture of distal radius were treated, including 32 males and 20 females and aging 21-60 years old (mean 47 years old). Fracture was caused by tumbl ing in 30 cases, by fall ing from height in 8 cases, by traffic accident in 11 cases, and by a crashing object in 3 cases. Of 52 cases,there were 50 cases of closed fracture and 2 cases of open fracture. According to AO standard of classification, there were 14 cases of B2 type, 16 cases of B3 type, 15 cases of C1 type, 6 cases of C2 type, and 1 case of C3 type. According to the Cooney’ s general standard of classification of unstable fracture, there were 5 cases of type II, 10 cases of type III, and 37 cases of type IV. The time from injury to operation was 3-14 days (mean 5 days). All patitents received open reduction and T-shaped plate fixation. Seven patients having bone defect were given 6-15 g autologous il ium or 5 mL calcium sulphate artificial aggregate after reduction. Results All incisions healed by first intention. All the patients were followed up for 15 to 30 months postoperatively (mean 24 months). The X-ray films showed good anatomical reduction, even articular surface and no lossening of internal fixation in all the cases. The fractures healed within 9-15 weeks after operation (mean 12 weeks). At last follow-up, the mean palmar tilt was 8° and the mean ulnar variance was 21°, showing statistically significant differences when compared preoperation (— 5° and 5°, P lt; 0.05). The radial length were not abbreviated. According to Dienst assessment, the results were excellent in 42 cases, good in 3 cases, fair in 5 cases and poor in 2 cases 12 weeks after operation, and the excellent and good rate was 86.5%. Conclusion T-shaped plate fixation is rel iable and effective in treatment of intra-articular fracture of distal radius because it has less coml ication of infection, loosening of internal fixation, reduction failure and tendon rupture.
Objective To compare the effectiveness of open reduction and conservative treatment for pediatric mandibular condylar fractures and to provide the evidence for the selection of cl inical therapy. Methods The cl inical data were retrospectively analyzed from 25 patients with the mandibular condylar fractures between January 1988 and December 2006. Of them, 8 patients (11 fractures) were treated with surgical treatment (surgical group) and 17 patients (22 fractures) withnon-surgical treatment (non-surgical group). In surgical group, there were 6 males (9 fractures) and 2 females (2 fractures) with an age range of 8-13 years; fracture was caused by tumbl ing in 7 cases and by traffic accident in 1 with an interval of 1-6 days between injury and hospital ization; and 5 cases were identified as unilateral condylar fractures (3 compl icated by mental fractures) and 3 cases as bilateral condylar fractures compl icated by mental fractures. In non-surgical group, there were 12 males (15 fractures) and 5 females (7 fractures) with an age range of 3-12 years; fracture was caused by fall ing from height in 4 cases, by tumbl ing in 10, and by traffic accident in 3 with an interval of 1-25 days between injury and hospital ization; and 12 cases were identified as unilateral condylar fractures (3 compl icated by mental fractures) and 5 cases as bilateral condylar fractures (1 compl icated by mental fracture). Results Incision healed by first intention in surgical group, and 25 cases were followed up 1-6 years with an average of 3.5 years. At 12 months after treatment, no temporomandibular joint pain, eating disorder, or l imited mandibular movement occurred in 2 groups. No significant difference was observed in opening mouth extent, protrusive and lateral movements between 2 groups at 6 and 12 months (P gt; 0.05). During centric occlusion, mental point located at the midl ine with symmetric face figure. Two patients in surgical group and 3 in non-surgical group had sl ight snap when opening their mouths. Mandible deviation was observed in 3 patients of 2 groups, respectively when gaping. The X-ray films showed heal ing of fracture and condylar remodel ing at 3-6 months. Mandibular ramus were symmetric in cephalometry. Conclusion Good effectiveness can be obtained by surgical or non-surgical treatment in pediatric mandibular condylar fractures. Considering the pediatric mandibular condyle having powerful heal ing and reconstructing potency and avoiding secondary injury on the temporomandibular joint from surgery, non-surgical treatment should be first selected for the pediatric mandibular condylar fractrues in patients under 7 years.
Objective To compare the effectiveness between minimally invasive plate osteosynthesis (MIPO) and open reduction and internal fixation (ORIF) for treatment of extra-articular distal tibial fracture. Methods Between March 2009 and March 2012, 57 patients with extra-articular distal tibial fractures were treated, and the clinical data were retrospectively analyzed. Of 57 cases, 31 were treated with MIPO (MIPO group), and 26 with ORIF (ORIF group). There was no significant difference in gender, age, cause of injury, type of fractures, complication, and time from injury to operation between 2 groups (P gt; 0.05). The operation time, intraoperative blood loss, fracture healing time, and complications were compared between 2 groups. Results There was no significant difference in operation time and intraoperative blood loss between 2 groups (P gt; 0.05). Wound infection occurred in 5 cases [2 in MIPO group (6.5%) and 3 in ORIF group (11.5%)], showing no significant difference (χ2=0.651, P=0.499). The other wound obtained healing by first intention. All cases were followed up 13-24 months (mean, 15 months). No significant difference was found in the average healing time between 2 groups and between patients with types A and B by AO classification (P gt; 0.05); in patients with type C, the healing time in MIPO group was significantly shorter than that in ORIF group (t= — 2.277, P=0.033). Delayed union was observed in 3 cases of MIPO group (9.7%) and in 4 cases of ORIF group (15.4%), showing no significant difference (χ2=0.428, P=0.691). Mal-union occurred in 4 cases of MIPO group (12.9%) and in 1 case of ORIF group (3.8%), showing no significant difference (χ2=1.449, P=0.362). No significant difference was found in Mazur score between 2 groups (t=0.480, P=0.633). The excellent and good rate was 93.5% in MIPO group (excellent in 24 cases, good in 5 cases, fair in 1 case, and poor in 1 case) and was 92.3% in ORIF group (excellent in 18 cases, good in 6 cases, and poor in 2 cases), and the difference was not significant (Z= — 0.687, P=0.492). Conclusion Both MIPO and ORIF have good results in treating extra-articular distal tibial fractures. MIPO is superior to ORIF for treating complex and communited fractures.
Objective To assess the effectiveness of the new anterolateral approach of the distal femur for the treatment of distal femoral fractures. Methods Between July 2007 and December 2009, 58 patients with distal femoral fractures were treated by new anterolateral approach of the distal femur in 28 patients (new approach group) and by conventional approach in 30 patients (conventional approach group). There was no significant difference in gender, age, cause of injury, affected side, type of fracture, disease duration, complication, or preoperative intervention (P gt; 0.05). The operation time, intraoperative blood loss, intraoperative fluoroscopy frequency, hospitalization days, and Hospital for Special Surgery (HSS) score of knee were recorded. Results Operation was successfully completed in all patients of 2 groups, and healing of incision by first intention was obtained; no vascular and nerves injuries occurred. The operation time and intraoperative fluoroscopy frequency of new approach group were significantly less than those of conventional approach group (P lt; 0.05). But the intraoperative blood loss and the hospitalization days showed no significant difference between 2 groups (P gt; 0.05). All patients were followed up 12-36 months (mean, 19.8 months). Bone union was shown on X-ray films; the fracture healing time was (12.62 ± 2.34) weeks in the new approach group and was (13.78 ± 1.94) weeks in the conventional approach group, showing no significant difference (t=2.78, P=0.10). The knee HSS score at last follow-up was 94.4 ± 4.2 in the new approach group, and was 89.2 ± 6.0 in the conventional approach group, showing significant difference between 2 groups (t=3.85, P=0.00). Conclusion New anterolateral approach of the distal femur for distal femoral fractures has the advantages of exposure plenitude, minimal tissue trauma, and early function rehabilitation training so as to enhance the function recovery of knee joint.
Objective To compare the effectiveness of arthroscopy assisted percutaneous internal fixation and open reduction and internal fixation for Schatzker types II and III tibial plateau fractures. Methods Between August 2006 and April 2010, 58 patients with tibial plateau fractures of Schatzker types II and III were treated with arthroscopy assisted percutaneous internal fixation (arthroscopy group, n=38), and with open reduction and internal fixation (control group, n=20). There was no significant difference in gender, age, disease duration, fracture type, and compl ication between 2 groups (P gt; 0.05). The operation time, incision length, fracture heal ing time, and compl ications were compared between 2 groups. Knee function score and the range of motion were measured according to American Hospital for Special Surgery (HSS) scorestandard. Results All patients achieved primary incision heal ing. The arthroscopy group had smaller incision length andlonger operation time than the control group, showing significant differences (P lt; 0.05). The patients of 2 groups were followed up 12 to 14 months. At 6 months, the HSS score and the range of motion of the arthroscopy group were significantly greater than those of the control group (P lt; 0.05). The X-ray films showed bony union in 2 groups. The fracture heal ing time of the arthroscopy group was shorter than that of the control group, but no significant difference was found (t=2.14, P=0.41). Morning stiffness occurred in 2 cases (5.3%) of the arthroscopy group, joint pain in 6 cases (30.0%) of the control group (3 cases had joint stiffness) at 1 week, which were cured after symptomatic treatment. There was significant difference in the incidence of compl ications between 2 groups (χ2=6.743, P=0.016). Conclusion The arthroscopy assisted percutaneous internal fixation is better than open reduction and internal fixation in the treatment of tibial plateau fractures of Schatzker types II and III, because it has smaller incision length and shorter fracture heal ing time.
Objectives To systematically review the efficacy of conservative treatment and open reduction with internal fixation for multiple rib fractures. Methods We searched WanFang Data, CNKI, VIP, PubMed, EMbase, The Cochrane Library and Web of Science from inception to December 2017 to collect studies on conservative treatment and open reduction with internal fixation for multiple rib fractures. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. RevMan 5.3 software was used for meta-analysis. Results A total of 16 studies were included, involving 1 374 patients, 723 patients in the surgical group and 651 patients in the conservative group. The meta-analysis showed that the length of stay in the ICU (MD=–3.41, 95%CI –4.92 to –2.43, P<0.000 01), total length of stay (MD=–7.60, 95 %CI–10.67 to–4.53,P<0.000 01), incidence of pulmonary arylene (RR=0.40, 95%CI 0.29 to 0.54,P<0.000 01), incidence of lung infections (RR=0.43, 95%CI 0.30 to 0.61,P<0.000 01), and incidence of chest wall malformation (RR=0.05, 95%CI 0.03 to 0.11,P<0. 0.000 01) in the surgical group were superior to the conservative group. Conclusions Compared with conservative treatment, open reduction with internal fixation can significantly improve the recovery time of patients with multiple rib fractures, reduce hospitalization time, the incidence of perioperative complications, and significantly enhance the prognosis of patients, which is more conducive to the rehabilitation of patients.
