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.
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 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.
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.
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 discuss the relationship between recovery of anatomical integrity and functional outcome in elderly patients with distal radius fractures by comparing the effects of open reduction and closed reduction. Methods The cl inical data were retrospectively analyzed from 78 elderly patients with distal radius fractures treating with nonoperation andoperation from February 2005 to March 2009. Thirty-seven patients underwent closed reduction and spl intlet fixation or cast appl ication (non-operation group), and forty-one patients underwent open reduction and internal fixation (operation group). In non-operation group, there were 15 males and 22 females with an average age of 73 years (60-83 years). According to the AO classification system for fracture, there were 8 cases of type A2, 7 cases of type A3, 7 cases of type B1, 4 cases of type B2, 2 cases of type B3, 4 cases of type C1, 2 cases of type C2, and 3 cases of type C3. The time from injury to admission was between 30 minutes and 3 days with a mean time of 1 day. In operation group, there were 18 males and 23 females with an average age of 71 years (62-80 years). According to the AO classification system for fracture, there were 5 cases of type A2, 7 cases of type A3, 7 cases of type B1, 6 cases of type B2, 3 cases of type B3, 4 cases of type C1, 5 cases of type C2, and 4 cases of type C3. The time from injury to admission was between 30 minutes and 7 days with a mean time of 1 day. There were no significant differences (P gt; 0.05) in sex, age, disease course and fracture classification between two groups. Results All incisions obtained heal ing by first intention after operation in operation group. All patients were followed up for 9-36 months (20 months on average). Fracture heal ing was achieved within 8 to 15 weeks, with an average of 11 weeks. There were no significant differences (P gt; 0.05) in fracture heal ing time between non-operation group [(10.8 ± 2.0) weeks] and operation group [(11.7 ± 2.5) weeks]. At last follow-up, thepalmar tilt angle was (5.6 ± 2.0)° and (8.6 ± 3.0)°, the radial incl ination angle was (19.1 ± 4.9)° and (21.8 ± 2.0)°, and the radial length was (8.3 ± 1.3) mm and (10.4 ± 1.4) mm in non-operation group and operation group, respectively; showing significant differences (P lt; 0.05) between two groups. According to the Gartland-Werley score, the results were excellent in 9 cases, good in 21 cases, fair in 5 cases, and poor in 2 cases in non-operation group, the excellent and good rate was 81.1%; in operation group, the results were excellent in 13 cases, good in 25 cases, fair in 2 cases, and poor in 1 case, the excellent and good rate was 92.7%, showing no significant difference (P gt; 0.05) between two groups. There were no significant differences (P gt; 0.05) in flexion and extension activity of wrist, radioulnar partial activity, pronation-supination activity, grip and pinch strength between two groups. Conclusion Open reduction and closed reduction can achieve satisfactory functional outcomes, but closed reduction was inferior to open reduction in anatomic reduction for treating distal radius fractures in elderly patients.
Objective
To investigate the effectiveness of the acetabular reconstruction surgery in children pathological dislocation of the hip joint.
Methods
Between January 2006 and January 2011, 59 patients (59 hips) with pathological dislocation were treated by open reduction combined with acetabular reconstruction surgery. There were 22 boys and 37 girls, aged from 1 to 15 years (mean, 4.9 years). There were 9 cases of hip subluxation and 50 cases of hip joint dislocation, which were caused by suppurative arthritis of the hip (33 cases) and tuberculosis of the hip (26 cases). The diseases duration ranged from 1 month to 10 years. At preoperation Harris hip score was 43-78 (mean, 61); 14 cases had normal acetabular index (AI), 32 cases had slightly increased AI, and 13 cases had significantly increased AI. The concomitant diseases included acetabular destruction in 28 cases; avascular necrosis of the femoral head in 25 cases, femoral head partial defect in 12 cases, femoral head complete defect in 6 cases, and femoral head and neck defects in 3 cases; 25 cases had increased anteversion angle; and 9 cases had varus deformity.
Results
Immediately postoperative X-ray films showed center reduction in all the hips. Healing of incision by first intention was achieved in 55 cases, and delayed healing in 4 cases. Fifty-three children were followed up 2 to 5 years (mean, 3 years). No re-dislocation of the hip occurred during follow-up. Thirty-eight cases had normal AI, 15 cases had slightly increased AI. The anteversion angle was 15-25
°
(mean, 20
°
); the neck shaft angle was 110-140
°
(mean, 125
°
); and the anatomical relation between the head and neck returned to normal. After 2 years, 18 cases had normal function of the hip joint; 30 cases had mild limitation of flexion and rotation; and 5 cases had fibrous ankylosis. The Harris hip score was 62-95 (mean, 87).
Conclusion
Pathological dislocation caused by neonatal acute suppurative arthritis of the hip and the hip joint tuberculosis is often associated with severe bone destruction and deformity of the acetabular and femoral head and neck. Treatment should strictly follow the principle of individual. Proper acetabular reconstruction should be selected according to pathological changes of the hip; if combined with the femoral head and neck reconstruction processing, the satisfactory results can be obtained.
ObjectiveTo compare the effectiveness between open reduction and closed reduction of pediatric subtrochanteric fractures using elastic stable intramedullary nailing (ESIN).
MethodsBetween January 2010 and January 2014, 22 children with subtrochanteric fractures were treated by ESIN internal fixation combined with hip cast fixation, and the clinical data were retrospectively reviewed. Closed reduction was used in 12 cases (group A) and miniopen reduction in 10 cases (group B). There was no significant difference in gender, age, sides, fracture causes, type of fracture, complications, and time from injury to operation between 2 groups (P>0.05). The operation time, intraoperative blood loss, fracture healing time, and complications were recorded and compared between 2 groups, the limb function was evaluated according to the Flynn et al. outcome score.
ResultsThe intraoperative blood loss of group A was significantly less than that of group B, but the operation time of group A was significantly longer than that of group B (P<0.05). All the patients were followed up 12-36 months (mean, 14.9 months). There was no major complications in the other patients of both groups except 1 patient having delayed wound healing in group B. There was no significant difference in fracture healing time between 2 groups (t=-1.006, P=0.327). Inverted angle of 10° and shortened limb of 1.8 cm were observed in 1 case of group A, and sagittal plane angle of 15° and shortened limb of 2 cm in 1 case of group B. There was no abnormal walking and function of hip and knee activity at last follow-up. According to the Flynn et al. outcome score, the results were excellent in 8 cases and good in 4 cases in group A, and were excellent in 6 cases and good in 4 cases in group B, showing no significant difference between 2 groups (χ2=0.041, P=0.956).
ConclusionBoth closed and open fracture reduction using ESIN have satisfactory outcomes for treating pediatric subtrochanteric fractures. A mini-open reduction should be selected intraoperatively if closed reduction proves to be difficult.
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.
