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.
ObjectiveTo compare the clinical results between percutaneous poking reduction fixation and open reduction and internal fixation for the displaced Sanders Ⅱ type calcaneal fractures. MethodsA retrospective analysis was made on the clinical data of 122 patients with Sanders Ⅱ type calcaneal fractures between May 2007 and May 2012, who accorded with the inclusion criteria. The closed reduction and percutaneus Kirschner wire fixation were used in 61 patients (closed group), and open reduction and internal fixation were used in 61 patients (open group). There was no significant difference in gender, age, fracture side, weight, height, body mass index, the causes of injury, the fracture type, Böhler angle, Gissane angle, and the time from trauma to operation between 2 groups (P>0.05). The operation time, intraoperative blood loss, hospitalization days, wound complications, fracture healing time, American Orthopaedic Foot and Ankle Society (AOFAS) score, and radiographic results were compared between 2 groups. ResultsThe operation time, intraoperative blood loss, and hospitalization days in closed group were significantly less than those in open group (P<0.05). There was no deep infections in both group; wound dehiscence, skin flap necrosis, and wound infection occurred in 3 patients, 2 patients, and 1 patient of the open group, no wound complication happened in closed group, and there was significant difference in the incidence of wound complications between 2 groups (P=0.027). The patients were followed up 24-68 months (mean, 38.7 months) in the closed group and 26-66 months (mean, 38.7 months) in the open group. There was no significant difference in the fracture healing time between 2 groups (t=-1.562, P=0.121). The Böhler angle and Gissane angle at last follow-up were significantly improved when compared with preoperative angle in the closed group (t=-27.929, P=0.000; t=-26.351, P=0.000) and the open group (t=-32.565, P=0.000; t=-25.561, P=0.000), but there was no significant difference between 2 groups (P>0.05). AOFAS score showed no significant difference between 2 groups (t=-0.492, P=0.624). ConclusionFor the displaced Sanders Ⅱ type calcaneal fractures, the use of closed reduction and percutaneus Kirschner wire fixation or open reduction and internal fixation can both obtain satisfactory clinical function and radiographic results, but the former has the advantage of less trauma, shorter hospitalization time, and fewer wound complications.
Objective To evaluate the effectiveness and safety of external fixation (EF) and open reduction and internal fixation (ORIF) for unstable distal radius fractures in adults. Methods We searched MEDLINE (1966 to September 2008), Cochrane Central register of controlled Trials (The Cochrane Library, Issue 3, 2008), EMbase (1974 to September 2008), CBM, CNKI, and collected randomized controlled trials (RCTs) of EF and ORIF for unstable distal radius fractures in adults. The quality of the included studies was critically assessed and data analyses were performed with the Cochrane Collaboration’s RevMan 5.0 software. Results Seven RCTs involving 634 patients were included, of which 269 were in EF group, and 293 were in ORIF group. Only 1 study had relative high quality, all the others had some limitation in randomization, blinding, and allocation concealment. The results of meta-analyses showed that, 1) about the effectiveness: according to the Gartland and Werley grade standard, the ORIF group was better than the EF group with statistic difference (RR=1.50, 95%CI 1.11 to 2.03, P=0.008); because of the original studies did not offer the detailed data including pad strength, grip strength, flexion-extension, radial deviation, and ulnar deviation, we only processed a descriptive analysis; and 2) about complications: the infection rate of the pin track was higher in the EF group than that in the ORIF group with statistic difference (RR=0.24, 95%CI 0.08 to 0.76, P=0.02); but there were no differences between the two groups in reflex sympathetic dystrophy (RSD) (RR=0.88, 95%CI 0.30 to 2.56, P=0.82), extensor tendon rupture (RR=3.93, 95%CI 0.45 to 34.62, P=0.22), and compartment syndrome (RR=3.13, 95%CI 0.51 to 19.09, P=0.22). Conclusions Compared with EF, ORIF is much better based on Gartland and Werley grade standard, and causes much less infection. Because of the limited quality and quantity of the included studies, more proofs are required from more RCTs with large sample.
Objective To explore the choice for the internal fixation in treatment of pelvic posterior lesions. Methods From May 2000 to June 2005, the treatment was given to 40 patients (28 males, 12 females,aged 21-58 years) with pelvic posterior ring fracture and dislocation. Of the patients, 23 had a traffic accident, 11 had a crush injury and 6 had a fall. As for the state of an injury to the pelvic posterior ring, 22 patients had disloation of the sacroiliac joint, 12 had a sacrum fracture dislocation, and 6 had an ala iliac fracture and disloation of the sacroiliac joint. According to the Denis(1988) classification, fracture of the (sacral region Ⅰ was found in 6 cases, fracture of the scaral) region Ⅱ in 3 cases, and fracture of the scaral region Ⅲ in 3 cases. As for the complication of the pelvic front ring fracture:separation of the symphysis pubis was found in 14 cases, fraclure of the superior ramus and inferior ramus of the pubis on one side in 10 cases. The two-side superior ramus of publis and inferion ramus of pubisin 8 cases, homopleural acetabular fracture on one side in 4 cases, acetabularfracture on one side and contralateral superior ramus and inferior ramus fracture of the pubis in 3 cases, and acetabular fracture on the opposite side in 1 case.As for the operation, 28 patients underwent the stillplate internal fixation of the sacroiliac joint from anterior at 24 h to 15 days after the injury, 2 underwent the screwinternal fixation of the sacroiliac joint from posterior, and remaining 10 underwent the internal fixation by the Galveston Technique associated with the ISOLAsystem. The therapeutic results were analyzed. Results The followup of the 40 patients for 6 months to 3 years revealed that before operation 3 had a sacral plexus nerve injury, and after operation 1 patient developed perineum numbness and urinary incontinence, 1 developed claudication，3 developed posterior urethral fragmentation, and 2 developed urinary bladderrupture; however, they had a complete recovery after the reparative surgery. Conclusion In treatment of the pelvic posterior ring lesions，an appropriate internal fixation can be chosen according to the type of the pelvic fracture，applicability of internal fixation， condition of the patient，equipment available, and the doctor’s experience.
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 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 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 analyze and compare the effectiveness of the closed reduction with elastic intramedullary nail ing and open reduction with Kirschner wire fixations in the treatment of O’Brien type III radial neck fractures in children. Methods Between November 2007 and November 2010, 31 children with O’Brien type III radial neck fractures were treated by the closed reduction with elastic intramedullary nailing fixation (closed reduction group, n=18) and by the open reduction with Kirschner wire fixation (open reduction group, n=13). There was no significant difference in age, gender, disease duration, and fracture classification between 2 groups (P gt; 0.05). Results The incisions of 2 groups healed primarily. Allthe patients were followed up 1-2 years (mean, 1.5 years). Limitation of the elbow extension occurred in 2 cases of the closed reduction group, l imitations of the elbow extension, flexion, and forearm pronation in 6 cases of the open reduction group. There was no significant difference in elbow flexion, extension, pronation, and supination between affected side and normal side in the closed reduction group (P gt; 0.05). Except in supination (P gt; 0.05), there were significant differences in flexion, extension, and pronation between affected side and normal side in the open reduction group (P lt; 0.05). According to Metaizeau’s grading criterion, excellent results were achieved in 16 cases and good in 2 cases in the closed reduction group; excellent results were achieved in 4 cases, good in 4 cases, fair in 3 cases, and poor in 2 case in the open reduction group; and there was significant difference between 2 groups (Z=3.435, P=0.001). The X-ray films showed anatomical reduction in 2 groups before removal of internal fixation; redisplacement occurred in 4 cases after removal of internal fixation in the open reduction group, no redisplacement occurred in the closed reduction group. There was no avascular necrosis of radial head and epi physes during follow-up. Conclusion Comparison with the open reduction with Kirschner wire fixation, the closed reduction with elastic intramedullary nailing fixation is a rel iable and good treatment for O’Brien type III radial neck fractures in children, because it has the advantages of minimal invasion, easy operation, stable fixation, early mobilization, and less complication.
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.
ObjectiveTo investigate the clinical results of modified subinguinal approach without iliac osteotomy for anterior surgical treatment of acetabular fractures which involve the anterior wall and medial wall or in combination with femoral neck fracture. MethodsThe subinguinal approach was modified after anatomical study on 12 adult cadavers. Between May 2010 and March 2012, 34 patients with acetabular fracture that involved the anterior wall and medial wall or in combination with femoral neck fracture were treated with open reduction and internal fixation through modified subinguinal approach in 15 cases and through modified subinguinal approach combined with Kocher-Langenbeck approach. There were 28 males and 6 females with an average age of 31.1 years (range, 20-64 years). According to the Letournel-Judet classification, there were 15 cases of anterior acetabular/column fractures, 8 cases of anterior acetabular/column fractures combined with trear half transverse fractures, 7 cases of double column fractures, and 4 cases of T shape fractures. The time between injury and operation was 5-16 days (mean, 7.4 days). ResultsAnatomy results: the inguinal ligament was reflection and continuity from the aponeurosis of obliquus externus abdominis with a length of (11.09±0.24) cm, which form part of abdominal muscle. The conjugate of inguinal ligament and iliopsoas muscle on the anterosuperior iliac spine was (0.69±0.08) cm. The vertical distance from the saphenous vein to the inguinal ligament was (3.58±0.49) cm. Clinical results: all the cases were followed up 4-24 months (mean, 14.6 months). No complication was observed, such as wound infection, internal fixation loosening, and iatrogenic injury to the sciatic or femoral nerve. The bone union time was 12-16 weeks (mean, 14 weeks). According to Matta reduction criteria for acetabular fractures, anatomic reduction were achieved in 21 cases, satisfactory reduction in 10 cases, and unsatisfactory reduction in 3 cases at 1 week after operation. According to D'Aubigne and Postel criteria for hip function, the results were excellent in 25 cases, good in 4 cases, fair in 3 cases, and poor in 2 cases at last follow-up. Heterotopic ossification (Brooker's grade I) occurred in 8 cases. ConclusionThe modified subinguinal approach can keep the inguinal ligament intact, provide broad visualization of anterior and medial wall of acetabulum and anterior hip capsule, which is a better modification and supplement for classic ilioinguinal approach.
