ObjectiveTo study the surgical treatment method and effectiveness of Rüedi-Allg?wer Ⅲ type Pilon fractures. MethodsBetween May 2011 and April 2013,25 cases of Rüedi-Allg?wer Ⅲ type Pilon fracture (5 cases of open fractures and 20 cases of closed fractures) were treated.Of 25 cases,16 were male,and 9 were female,aged 24-45 years (mean,31 years).The left side was involved in 8 cases,and the right side in 17 cases.The disease causes were falling from height in 11 cases,traffic accident injury in 9 cases,and crash injury in 5 cases.The interval of injury and admission was 10-36 hours (mean,23.5 hours).The open reduction and internal fixation by posterolateral fibular incision and exposure of distal tibia and tibiotalar articular surface by anterior ankle incision were performed;the tibiotalar articular surface was reset and the tibia fracture end was fixed. ResultsHealing of incision by first intention was obtained in 15 cases,and healing by second intention in 6 cases undergoing skin grafting.Tension blister occurred in 4 patients,who achieved healing by second intention after treatment.All 25 patients were followed up 6-12 months (mean,8 months).During follow-up,no complication of ankle joint instability,traumatic arthritis,or loosening and breakage of internal fixation occurred.The X-ray films showed stable ankle joint,anatomic or near anatomic reduction of the tibiotalar articular surface,normal alignment of distal tibia,and good bony healing.At 6 to 12 months after operation,the flexion and extension of the ankle were normal,without pain of the ankle joint after removal of internal fixation.According to Mazur et al.rating system for ankle symptoms and function,the results were excellent in 5 cases,good in 12 cases,fair in 5 cases,and poor in 3 cases;the excellent and good rate was 68%. ConclusionThe procedure by anterior ankle lateral approach and posterolateral fibular approach can completely expose the tibiotalar articular surface,which is advantageous to displaced fracture reduction and fixation,and can achieve good effectiveness in treating Rüedi-Allg?wer Ⅲ type Pilon fractures.
OBJECTIVE: To observe the clinical results in the anterior stabile operation of spinal fracture using red blood salvage. METHODS: Nineteen cases with spinal fracture were performed the anterior decompress operation. Blood cell salvage were used during operation. Other 20 cases were also reviewed as control group, who were received the same operation without blood cell salvage. RESULTS: In the 19 cases, average volume of autologous transfusion was 536 ml. Only two cases had homologous transfusion requirements. In the control group, all cases needed homologous transfusion (averaged 947 ml). CONCLUSION: In the anterior decompress operation, the intraoperative blood salvage is highly effective in reducing transfusion and also improves the security of operation
Objective To study the surgical reconstruction for correction of enophthalmos deformity caused by orbital blowout fractures. Methods From December 1996 to March 2004, 56 cases of enophthalmos deformity caused by orbital blow-out fracture were repaired. There were 37 cases diplopia, 35 cases with worsened visual acuity than pretrauma. Typical sub-ciliary incision was employed to expose the fractured area.The dissection was done beneath the medial and inferior obital periosteum. The fracture areas were exposed and the tissues protrusing to sinus maxillaries were released through the space between fractural bones. After the medial and inferior orbital walls and orbital floors were exposed，the herniated orbital contents were released and reduced to the orbital cavity. The fractured orbital walls were repaired precisely with Medpor which were fixed to the area beneaththe periosteum with 2 plates at least. Results All 56 cases ofenophthalmos deformity caused by orbital blow-out fracture repaired with this technique recovered well and their facial appearance improved greatly. With a follow-up ranged from 2 months to 5 years, the degree of enophthalmos stabilized at within 2 mm, no relapse and other complications occurred. Of 34 patients with diplopia, 27 were improved. Of the 35 cases with worsened visual acuity, 9 were improved with different degree. No diplopia or visual acuity worsening occurred. Conclusion It is safe and effectiveto correct the orbital blow-out fractures. The earlier it is repaired, thebetter the effect will be. Medpor with its advantages like better histocompatibility, easier sculpturing, moderate hardness, lower absorptivity, fewer complications and permanence effect is the preferable implantation material for correcting enophthalmos deformity.
Since October 1984, we have designed a method of conversed transplant of radial styloid bone flap with fascial pedicle in the treatment of 22 patients with non-united waist fractures of carpal scaphoid. The results from follow-up of 2-7 years were satisfactory.This article introduced the design of the bone flap, the operative procedure and the advantages of the bone flap.
Objective To study the effect and complication of repairing depressed fracture of frontal part with hydroxylapatite particulate artificial bone. Methods From January 1994 to December 2002, 13 patients were all diagnosed as having depressed fracture of frontal part with clinical and X-ray examinations. Thesmall incision before the hair-edge or local small incision was made. After opening the incision, we performed creeping decollement. Then the hydroxylapatite particulate artificial bone was implanted into the sites of the depressed fracture. The effect and complication were observed with clinical and X-rayexaminations in all patients 1 week, 1 month, 3 months after operation.Results The quantity of hydroxylapatite implanted was 10-30g. Primary healing was obtained in all cases without any complication. All cases were followed up for 3 months. The contours of the frontal part were restored well. Conclusion It is a good method to repair depressed fracture of frontal part with hydroxylapatite particulate artificial bone.
Objective To compare the differences between volar and dorsal plate positions in the treatment of unstable fracture of distal radius. Methods From June 2000 to December 2006, 61 cases with fracture of distal radius weretreated, 27 males and 34 females aged 22-70 years (55.5 years on average), among which 18 cases were caused by traffic accidents and 43 cases falls. All cases were fresh closed fractures. All patients had AP and lateral X-ray films of the wrist preoperatively and 30 cases experienced CT scan. According to AO, there were 25 cases for B1, 18 for B2, 7 for B3, 7 for C1, and 4 for C2. All the cases were randomized into 2 groups: the wrist palmar group (group A, n=34) and dorsal group (group B, n=27), to perform volar and dorsal plate fixation, respectively. As to the measurement of fortune for the preoperative ruler and incl ination angle, group A were (—45.0 ± 53.0)o and (8.6 ± 3.1)o, respectively, and group B were (—40.0 ± 30.0)o and (7.3 ± 5.6)o, respectively. Preoperative radial shortened (12.0 ± 5.3) mm in group A, and (10.3 ± 4.2) mm in group B. Joint surface level was (4.3 ± 2.2) mm in group A, and (4.1 ± 3.3) mm in group B. Results All of the 61 cases were followed up for 6-27 months (16 months on verage). All the fractures were healed, the time to heal ing in group A was (8.2 ± 1.6) weeks, and in group B was (8.1 ± 1.2) weeks, and the difference was not significant (P gt; 0.05). As for the wrist function by Cartland-Werley scoring at the 8th week after operation, 7 cases were excellent, 10 good, and 17 poor in group A with the choiceness rate of 50.0%, while 7 cases were excellent, 11 good and 9 poor in group B with the choiceness rate of 66.7%. There was significant difference between the two groups (P lt; 0.01). And at the 24th week after operation, 21 cases were excellent, 9 good, and 4 poor in group A with the choiceness rate of 88.2%, while 18 cases were excellent, 5 good, and 4 poor in group B with the choiceness rate of 85.2%. There was no significant difference between the two groups (P gt; 0.05). As for radiological assessment by Sarmiento, device and palm incl ination angles in group A were (9.5 ± 3.1)o and (18.0 ± 8.2)o, respectively, and in group B were (11.0 ± 4.7) o and (16.0 ± 7.6)o, respectively. No radial shortening was found either in group A or in group B, and joint surface level in both groups were less than 1 mm. There was no significant difference between group A and group B in terms of all indicators postoperatively (P gt; 0.05), but there was significant difference when compared with preoperation (P lt; 0.001). With regard to comparison of postoperative compl ications between the two groups, there was no significant difference (P gt; 0.05) in early postoperative compl ications, but there was in long-term compl ications (P lt; 0.01). Conclusion The volar and dorsal plate positions may offer effective stabil ity for unstable distal radial fracture and early functional exercise. The volar plate position may influence the pronation function of the wris joint in the short run, while the dorsal plate position may cause more compl ications in the long run.
To investigate the therapeutic effect of open reduction, bone grafting, and internal fixation with plastic ti-alloy plate on intra-articular calcaneal fracture. Methods From January 2005 to December 2007, 32 patients (37 feet) with intra-articular calcaneal fracture underwent open reduction, bone grafting of autogeneic il ium (30-80 g) and internal fixation of plastic ti-alloy plate. There were 21 males and 11 females aged 18-56 years old (average 42.1 years old). There were 5 cases of bilateral calcaneal fracture and 27 cases of unilateral calcaneal fracture, including 2 cases of open fracture and 30 cases of close fracture. According to Sanders classification system, there were 11 cases of type II, 18 cases of type III and 8 cases of type IV. Preoperatively, Bouml;hler angle was (— 9.6 ± 4.2)° and Gissane angle was (101.4 ± 10.6)°. Nine feet underwent emergency operation and 28 feet received operation 5-7 days after injury. Results The wounds of 34 feet healed by first intention. The wound margin of 3 feet was gray with a small amount of colorless exudates, and healed after dressing change. All patients were followed for 12-24 months (average 16 months). X-ray films displayed that the fracture all healed within 3-4 months after operation. At 6 months after operation, the Bouml;hler angle and the Gissane angle was (28.5 ± 6.1)° and (128.9 ± 4.8)°, respectively, indicating there were significant differences when compared with before operation (P lt; 0.05). According to Maryland foot score system, 15 cases were graded as excellent, 18 cases were good, 4 cases were poor, and the excellent and good rate was 89.19%. Conclusion Open reduction, bone grafting, and internal fixation with plastic ti-alloy plate is an effective method to treat intra-articular calcaneal fracture. Choosing right operational timing, performing subarticular surface grafting when necessary and using appropriate plastic ti-alloy plate internal fixation can minimize the incidence of postoperative compl ications
Objective To observe the effectiveness of locking compression hook plate in treatment of humeral greater tuberosity fractures. Methods Between March 2014 and September 2017, 16 patients with isolated humeral greater tuberosity fractures were terated with open reduction and internal fixation with locking compression hook plates. There were 11 males and 5 females, with an average age of 38.4 years (range, 22-67 years). The cause of injury was falling injury in 13 cases and sport injury in 3 cases. All patients were closed fractures. Of all patients, 14 patients accompanied with shoulder joint dislocations. CT scan showed the average displacement of fragment was 12.6 mm (range, 8-21 mm) after reduction. All patients began passive functional exercise at 3 days after operation. Results Primary healing of the incisons achieved in all patients, without complications such as infection and nerve injury. All patients were followed up 12-20 months (mean, 15.3 months). At 3 months after operation, X-ray film showed that all fractures achieved bone union, all of which met the imaging anatomical reduction standard. According to the Neer scoring criteria, 11 cases were excellent and 5 cases were good at last follow-up. One patint presented slight pain of shoulder joint and mild activity limitation, which relieved after 1 year. Conclusion The method of open reduction and locking compression hook plate internal fixation for isolated humeral greater tuberosity fractures has advantages, such as less intraoperative hemorrhage, mild postoperative pain, firm fixation, and allowing patients to perform functional exercise earlier, which is conducive to shoulder functional recovery and obtain satisfactory effectiveness.
Objective To introduce a method for fixation in periprosthetic fracture with locking compression plate (LCP). Methods Duringthe surgery, a long 12-hole LCP was placed to the lateral side of the femur. Six holes of the plate were placed proximal to the main fracture line to make sure that there could be enough cortex units for rigid fixation of proximal fragments. Locking screws used except for the most proximal hole where a 4.5 mm screw was used instead. Results The patient was pain free at the fracture site one week after the surgery,and was able to walk with a cane 3 months after the surgery. Bone union was evident radiographically 3 months after the surgery. There was no loose signs around the stem. Six months after the surgery, the patient recovered full function without pain. Conclusion In our experience from this case, LCP in treating periprosthetic fracture was easy and less time consuming, more over, extensive periosteal stripping could be avoided. LCP is a good choice in treating some periprosthetic fractures.
Objective To investigate the effect of limb salvage on treating osteosarcoma with pathological fracture. Methods From October 2002 to January 2003, 2 cases of osteosarcoma with pathological fracture were treated by limb salvage. Intraarterial chemotherapy was given by subcutaneous implantable delivery system with caffeine. Replacement with prosthesis was performed after 5 times of chemotherapy. Results Two patients were followed up for twenty-four months and 21 months respectively. No infection, aseptic loosening, local recurrence or metastasis occurred, and function recovery of joints was satisfactory. Conclusion Limb salvage can be considered in condition that primary osteosarcoma with pathological fracture can be treated by effective and comprehensive chemotherapy.
