Objective To introduce a clinical treatment for the reconstructionof calcaneal thalamus by bone autograft and subtalar arthrodesis for antiquatedintraarticular calcaneal fractures. Methods From July 2000 to October 2003, 11 cases with antiquated intraarticular calcaneal fractures were treated. Of the 11 cases, 9 were males and 2 females,whose ages ranged from21 to 48 years. All unilateral calcanei were involved in the 11 cases. The modified extended Lshaped approach lateral to calcaneus was adopted. The primary treatment was manipulation and immobilization with the reconstruction of calcaneal thalamus by bone autograft and subtalar arthrodesis. The average volume of the ilium for the autograft was 3.0 cm×2.5 cm×1.8 cm. Protruded osteophyte from the lateral wall of calcaneus were ablated in all 11 cases. Results All the 11 cases were followed up for 3 to 18 months, 11.5 monthson average. The reconstructed calcaneal thalamus was healed 10 to 12 weeks after the operation. Some of the patients could walk with load 8 weeks after the operation, and the average time for all the patients to walk with load was 13.2 weeks. There were 4 cases of excellent result, 5 cases of good result, and 2 cases of fair result, according to ZHANG Tieliang’s foot score system. Plain radiograph showed that Bohler angle, width of calcaneus and height of calcaneal thalamus were nearlyrestored to normal. Conclusion With the improvement of calcaneal abnormality and restoration of the shape and function of hind foot, reconstruction of calcaneal thalamus by bone autograft combined with subtalar arthrodesis is effective in treating antiquated intra-articular calcaneal fractures.
OBJECTIVE To evaluate the results of free auto-periosteal graft in primary repair of cartilage defect accompanying severe comminuted fractured of patella. METHODS From January 1992 to August 1998, seventeen cases with extensive cartilage defect due to severe comminuted fracture of patella were primarily repaired with free auto-periosteal graft. In these cases, there were whole patellar fracture in 9 patients, upper two third patellar fracture in 3 patients and lower two third patellar fracture in 5 patients. During operation, "S"-shaped incision along medial side of knee through intra-cavity pathway were used. After fixation of the patellar fracture and clearance of the residual cartilage in the fracture area, the cancellous bone was exposed and trimmed. The free periosteum was incised from the anterior medial side of upper tibia and then transplanted to the region of cartilage defect. The size of grafted periosteum ranged from 3 cm x 4 cm 5 cm 6 x cm. The knee joint was received passive motion at 7 days after operation. RESULTS All cases were followed up 8 to 74 months. There were excellent recovery in 12 patients and the function of knee joint was normal, better recovery in 4 patients and the function of knee joint was nearly normal, and moderate recovery in 1 patient and the function of knee joint was limited mildly. CONCLUSION Free auto-periosteal graft is a simple and effective treatment in primary repair of cartilage defect accompanying patellar fracture. It is valuable to apply in clinical practice.
Objective To estimate clinical effect ofspin iliac deep vascular pedicled periosteum flap in repairing traumatic femoral neck of theca inside fracture in young and middleaged. Methods From April 1993 to September 2001, 12 cases of traumatic femoral neck fracture were given diaplastic operation with fixation of 3 centre hollow pressed bolt and were conducted under os traction bed and "C" arm X-ray machine. Spin iliac deep vascular pedicled periosteum flap wasstripped off, and transferred to the front of femoral neck fundus，then transplanted to the narrow inside of fracture through outer open door of articular capsule.Results All patients were followed up for 17 years. All fracture healedwithout femoral head necrosis, but mild arthritis appeared in 7 cases.Conclusion Vascular pedicled periosteum flap transfer of young and middle-aged femoral neck fracture, by decompression of femoral neck and reconstruction of blood circulation, can promote the fracture healing and decrease the wound and blood circulation destroy.
ObjectiveTo compare the effectiveness of lateral approach minimally invasive plate osteosynthesis (MIPO) and helical plate MIPO in the treatment of proximal humeral shaft fractures. Methods The clinical data of patients with proximal humeral shaft fractures who underwent MIPO via lateral approach (group A, 25 cases) and MIPO with helical plate (group B, 30 cases) between December 2009 and April 2021 were retrospectively analyzed. There was no significant difference in gender, age, injured side, cause of injury, American Orthopaedic Trauma Association (OTA) fracture classification, and time from fracture to operation between the two groups (P>0.05). The operation time, intraoperative blood loss, fluoroscopy times, and complications were compared between two groups. The angular deformity and the fracture healing were evaluated according to anteroposterior and lateral X-ray films postoperatively. The modified University of California Los Angeles (UCLA) score for shoulder and the Mayo Elbow Performance (MEP) score for elbow were analyzed at last follow-up. Results The operation time in group A was significantly shorter than that in group B (P<0.05). However, the intraoperative blood loss and fluoroscopy times presented no significant difference between the two groups (P>0.05). All patients were followed up 12-90 months, with an average of 19.4 months. There was no significant difference in follow-up time between the two groups (P>0.05). In terms of the quality of postoperative fracture reduction, there were 4 (16.0%) and 11 (36.7%) patients with angulation deformity in group A and group B, respectively, and there was no significant difference in the incidence of angulation deformity (χ2=2.936, P=0.087). All fractures achieved bony union, there was no significant difference in fracture healing time between group A and group B (P>0.05); delayed union occurred in 2 cases and 1 case in group A and group B, respectively (healing time was 30, 42, and 36 weeks after operation, respectively). In group A and group B, 1 patient had superficial infection of incision, respectively; 2 patients and 1 patient had subacromial impact after operation, respectively; and 3 patients in group A had symptoms of radial nerve paralysis of different degrees; all of them were cured after symptomatic treatment. The overall complication incidence of group A (32%) was significantly higher than that of group B (10%) (χ2=4.125, P=0.042). At last follow-up, there was no significant difference in the modified UCLA score and MEPs score between the two groups (P>0.05). Conclusion Both lateral approach MIPO and helical plate MIPO can achieve satisfied effectiveness in the treatment of proximal humeral shaft fractures. Lateral approach MIPO may be beneficial to shorten the operation time, while the overall complication incidence of helical plate MIPO is lower.
Objective To study the clinical outcome of comminuted factures at distal femur and proximal tibia treated with AO less invasive stabilization systems (LISS). Methods The clinical data of 14 cases of distal femoral fracture and proximal tibial fracture from September 2003 to May 2005 were analyzed retrospectively. The injury was caused by traffic accident in 9 cases, by fall in 3 cases and by slipping in 2 cases. Of 14 cases, there were 5 open fractures and 9 close fractures, including 5 cases of distal femoral comminuted fracture and 9 cases of proximal shaft comminuted fractures. According to AO/OTA classification, the fractures were classified as 33C2 in 3 cases，33C3 in 2 cases,41A2 in 2 cases，41A3 in 2 cases，41B2 in 3 cases and 41C2 in 2 cases. All patients were treated by the internal fixation with LISS-distal femur or with LISS-proximal tibia. Healing of wounds, the X-ray films before and after operations, and therecovery of joint function were observed. Results The patients were followed up from 1 month to 20 months (11 months on average). Twelve cases achieved solid osseous unions from 3 months to 5 months postoperativly; 2 cases had a good reduction and recovered smoothly 2-3 months postoperatively. The results were excellent in 10 cases, good in 3 cases and fair in 1 case according to Johner-Wruhs knee scoring. The range of knee flexion-extension was 110-130° in 11 cases, 100° in 2 cases and 80° in 1 case. Conclusion LISS is an effective method of internal fixation for treating comminntedfracture of distal femur or proximal tibia. It has the advantages of less injury, satisfied reduction and reliable fixation.
Objectives To systematically review the economic burden of surgical treatment for ankle fracture in China. Methods PubMed, EMbase, CNKI, WanFang Data and VIP databases were electronically searched to collect studies on economic burden of surgical treatment for ankle fracture in China from inception to December 1st, 2017. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies. Description analysis were then performed by Excel software. Results A total of 67 studies were included. The analysis showed that: the average cost of hospitalization generally tend to rise during 2004 to 2013. The highest was 17 700 yuan in 2013. After 2013, the expense gradually stabilized. The average annual growth rate of hospitalization costs was 12.3% during 2004 to 2016. The percentage of hospitalization costs accounted for the per capita disposable income of households in region was stable during 2004 to 2016 (around 60%). Conclusions Although the average hospitalization costs in China generally show an upward trend, the percentage of hospitalization costs accounted for the per capita disposable income of household is relatively stable. The study on the indirect economic burden is required to be further carried out. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusions.
Objective To study the surgical procedures and results for treating the nonunion of lateral humeral condyle fracture combined with cubitus valgus in adolescents. Methods From June 2004 to October 2006, 5 patients with nonunion of lateral humeral condyle fracture and cubitus valgus were treated, including 3 males and 2 females aged 8-17 yearsold. Three cases received external fixation for 2-3 weeks in other hospital, while 2 cases were misdiagnosed as soft tissue injury. The patients were hospital ized after they were diagnosed with nonunion of lateral humeral condyle fracture and cubitus valgus 4-12 years after injury. Preoperatively, the angle of cubitus valgus deformity was 25-55° (average 44.8°), and the elbow motion range of flexion and extension was 135-140° (average 139°) and 0-20° (average 7°), respectively. One case with the symptoms of ulnar neuritis was diagnosed as incomplete injury of ulnar nerve. The time between admission to hospital and operation was 3-7 days. All the patients were treated with wedge shaped supracondylar osteotomy of the distal aspect of humerus and humerus lateral column reconstruction. Regular follow-up was conducted after operation and the elbow function was evaluated according to the scale system of Jupiter et al. Results All incisions healed by first intention and all the cases were followed up for 14-28 months (average 20 months). X-ray films revealed that bone union was attained in all the 5 cases, among which the bone union at the supracondylar osteotomy site was reached 5-8 weeks after operation (average 6 weeeks) and the bone union at the lateral column reconstruction site was reached 3-6 months after operation. The deformity of cubitus valgus was corrected in all thecases. At latest follow-up, the flexion motion of the elbow was 100-135° (average 121°), and the extension range was 0-30° (average 13°), the angle of postoperative cubitus valgus deformity was — 5-10° (average 2°). According to the system of Jupiter et al, 2 cases were excellent, 2 cases were good and 1 case was fair. One patient and symptoms of radial nerve traction injury after operation and achieved complete recovery 3 months later; and 1 case suffering from ulnar neuritis before operation recovered 6 months after operation. No other compl ications occurred. Conclusion It is effective to use wedge-shaped supracondylar osteotomy of the distal aspect of the humerus and lateral colum reconstruction through internal fixation to treat the nonunion of the lateral humeral condyle fracture combined with cubitus valgus.
【Abstract】 Objective To evaluate the cl inical outcome of free vascularized fibular associated with il iac graft intreatment of old femoral neck fracture. Methods From January 1994 to January 1997, 76 cases of old femoral neck fracture were treated with free vascularized fibular associated with il iac graft, including 54 males and 22 females, aging from 24 to 48 years with an average of 31.5 years. All of these fractures resulted from injury. There were 20 cases of Garden II, 41 of Garden III and 15 of Garden IV. Based on the location of fracture, there was 26 cases of subcapital, 42 cases of transcervical and 8 cases of basal. Sixty-five cases were treated with internal fixation, 7 cases with skin traction and 4 just with staying in bed. Their Harris score were from 52 to 72 with an average of 65.6. The time from injury to operation was 2-24 months. The size of free vascularized fibular was 6-8 cm and il iac graft was 3.0 cm×2.0 cm×1.5 cm. Results In 76 cases, 68 were followed up and all fractures healed within 4 to 6 months with an average of 5.2 months. The increased density in femoral head was observed 1 year after operation. After 10 years of operation, normal hip function was achieved in 63 cases（followed up 10.1 -12.4 years with theaverage as 10.5 years); the Harris score was 87.5 (84 to 94). The structure of femoral head was normal and the grafted fibular and il iac bone healed with the femoral, no elapse or cyst occurred. Five cases had been compl ied with total hip replacement for femoral head necrosis or other. Conclusion Free vascularized fibular associated with il iac graft is a good method to treat old femoral neck fracture.
ObjectiveTo explore the efficacy and safety of the axial load mechanical testing for removing external fixator. MethodsBetween January 2014 and August 2015, 27 patients with tibia and fibula fractures caused by trauma underwent an external fixation. Of 27 patients, 21 were male and 6 were female with the average age of 45 years (range, 19-63 years), including 7 cases of closed fracture and 20 cases of open fracture. X-ray film results showed spiral unstable fracture in 4 cases and comminuted unstable fracture in 23 cases. All patients underwent an external fixation. Bone nonunion occurred in 3 cases because of infection, and bone nonunion combined with bone defect occurred in 1 case, who received tibial osteotomy lengthening surgery. When X-ray film showed continuity high density callus formation at fracture site, axial load mechanical test was performed. If the axial load ratio of external fixator was less than 10%, the external fixator was removed. ResultsAt 21-85 weeks after external fixation (mean, 44 weeks), axial load mechanical test was performed. The results showed that the axial load ratio of external fixation was less than 10% in 26 cases, and the external fixator was removed; at 6 weeks after removal of external fixator, the patients could endure full load and return to work, without re-fracture. The axial load ratio was 14% in 1 case at 85 weeks, and the X-ray film result showed that fracture did not completely heal with angular deformity; re-fracture occurred after removing external fixator, and intramedullary fixation was used. ConclusionExternal fixator axial load mechanical testing may objectively reveal and quantitatively evaluate fracture healing, so it is safe and reliable to use for guiding the external fixator removal.
Objective To observe the cl inical results of treatment of Schatzker V/VI tibial plateau fracture involved posteromedial condyle through combined posteromedial and anterolateral approach and fixed with two or three plates. Methods From April 2005 to April 2008, 18 cases of tibial plateau fracture involved posteromedial condyle were treated, including 14 males and 4 females with an average age of 38.5 years old (range, 18-62 years old). According to Schatzker classification, there were 12 cases of type V and 6 cases of type VI. The posteromedial condyle were involved in 13 cases and bilateral posterior condyle in 5 cases. All patients were given posteromedial fragment and medial condyle fracture reduction through posteromedial approach firstly, and then lateral condyle fracture reduction through anterolateral approach, and injury of meniscuses and cruciate l igaments were treated at the same time. Three plates (lateral, medial, posterior) were used in 10 cases and two plates (lateral, posteromedial) in 8 cases. Results All wounds achieved heal ing by first intention without compl ications such as infection, flap necrosis, osteofascial compartment syndrome, chronic osteomyel itis, nonunion. All patients were followed up for 12 to 48 months with an average of 24.4 months. The mean flexion of the knee was 118.4° (range, 100-130°) 1 year after operation. According to Iowa evaluation system, 12 patients got excellent results, 4 good, and 2 fair; the excellent and good rate was 88.9%. Conclusion Combined posteromedial and anterolateral approach and fixed with two or three plates is effective in treatment of the Schatzker V/VI tibial plateau fracture involved posteromedial condyle. Anatomical reduction and rigid internal fixation of the posteromedial fragment are critical to successful operation.
