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 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.
ObjectiveTo investigate the clinical features of ankle fractures involving Tillaux-Chaput in adults, and to observe the surgical effectiveness. MethodsBetween May 2009 and May 2013, 15 adult patients with ankle fractures involving Tillaux-Chaput were treated by open reduction and internal fixation. There were 12 males and 3 females, with an average age of 32 years (range, 19-45 years). The causes included sport injury (8 cases), traffic accident injury (5 cases), and falling injury from height (2 cases). The left ankle was involved in 5 cases and the right side in 10 cases. There were 2 open fractures (Gustilo type I) and 13 close fractures. Five patients had single Tillaux-Chaput fractures. The mean time between injury and surgery was 8.5 days (range, 3 hours to 15 days). According to the Lauge-Hansen classification, there were 9 cases of supination-external rotation, 5 cases of pronation-external rotation, and 1 case of pronation-abduction. ResultsPrimary healing of incisions was obtained in 13 patients without infection and neurovascular injury; 2 patients had superficial infection which was cured after oral antibiotics and dressing change. All cases were followed up for 23 months on average (range, 13-36 months). X-ray films showed complete fracture healing at 10-16 weeks postoperatively (mean, 13 weeks) in all cases. The mean American Orthopaedic Foot and Ankle Society (AOFAS) score was 87 (range, 78-99), with an excellent and good rate of 80% (excellent in 9 cases, good in 3 cases, and fair in 3 cases). ConclusionOpen reduction and internal fixation for ankle fractures involving Tillaux-Chaput in adults can achieve excellent effectiveness.
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.
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.
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 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.
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 evaluate the effect of associated ulnar styloid fracture on wrist function after distal radius fracture by comparing the cl inical data between the cases of distal radius fracture with or without ulnar styloid fractures. Methods The cl inical data of 182 patients with distal radius fracture between February 2005 and May 2010 were retrospectively analyzed, including 75 with ulnar styloid fracture (group A), and 107 without ulnar styloid fracture (group B). There was no significant difference in sex, age, disease duration, and fracture classification between 2 groups (P gt; 0.05). In groups A and B, closed reduction and spl intlet or cast fixation were performed in 42 and 63 cases respectively, and openreduction and internal fixation in 33 and 44 cases respectively. All ulnar styloid fractures were not treated. Results Thepatients were followed up 21 months on average in group A and 20 months on average in group B. All incisions healed by first intention after operation. Ulnar wrist pain occurred in 4 patients (5.3%) of group A and 6 patients (5.6%) of group B, showing no significant difference (χ2=0.063, P=0.802). The fracture heal ing time was (10.9 ± 2.7) weeks in group A and (11.6 ± 2.3) weeks in group B, showing no significant difference (t=1.880, P=0.062). There was no significant difference in the palmar tilt angle, the ulnar incl ination angle, and the radial length between groups A and B when fracture healing (P gt; 0.05). At last follow-up, there was no significant difference in wrist flexion-extension, radial-ulnar deviation, pronation-supination, and grip and pinch strength between 2 groups (P gt; 0.05). According to the Gartland-Werley score in groups A and B, the results were excellent in 24 and 35 cases, good in 43 and 57 cases, fair in 5 and 10 cases, and poor in 3 and 5 cases with execllent and good rate of 89.3% and 86.0%, respectively, showing no significant difference between 2 groups (Z= —0.203, P=0.839). There were significant differences in the above indexes between patients undergoing closed reduction and open reduction in group A (P lt; 0.05). Conclusion Associated ulnar styloid fracture has no obvious effect on the wrist function after distal radius fracture. The anatomical reduction of distal radial fracture is the crucial importance in the treatment of distal radial fracture accompanying ulnar styloid fracture.
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.
