Objective To explore the surgical method and cl inical short-term outcomes of internal fixation combined closed reduction with arthroscope aid in treating patellar fracture. Methods From June 2004 to July 2008, 42 patients with fresh simple patellar fracture underwent internal fixation combined closed reduction with arthroscope aid, included28 males and 14 females, aged 16-59 years (35 years on average). The locations were 19 left knees and 23 right knees. Injury was by traffic accident in 21 cases, by fall ing in 11 cases, by sports in 7 cases and by crush in 3 cases. All the patients had fresh closed fracture, including 38 cases of transverse fracture and 4 cases of stellate fracture. The Lysholm score was 68.60 ± 15.20; the proprioceptive function of the knee joints was (3.72 ± 0.12)°. The time from injury to operation was 3-42 hours (12 hours on average). After the treatment of affil iated injury under the arthroscope, patellar fracture was reduced with manipulation method, fracture was fixed with tensile force screw or modified tension band. Results All incisions obtained heal ing by first intention after operation, 42 patients were followed up for 12-39 months (16 months on average). The X-ray films showed callus at the fracture and the smooth cartilage surface 6-9 weeks (7 weeks on average) after operation. The flexed motion range of knee joint at last follow-up was at normal range in 38 cases, was l imited in 4 cases. Circumference of suffered l imbs 15 cm above the patella was the same as normal ones in 23 cases, atrophied 0.7 cm in 19 cases. There were no breakage of internal fixation and shift of fracture and patellofemoral arthritis at last follow-up. The proprioceptive function of the knee joints was (2.06 ± 0.11)° and the Lysholm score was 95.10 ± 3.92; all showing statistically significant differences when compared with preoperation (P lt; 0.05). Conclusion This treatment method has advantages as follows: mini-wound, early exercises and few compl ications, which can rinse articular cavity and repair the affil iated injury at the same time.
Objective To introduce a new surgical approach to rectify the shortened lower limbs. Methods From March 1985 to October 2000,288 cases of shortened lower limbs were treated and reviewed. Closed fracture at the metaphysis was made by a self-made “needle saw”, and then the “multiple-plane and double-track elongation instrument” was adopted to elongate the fractured bone. There were totally 161 cases of male and 127 cases of female included, with average age 21.3 years old, ranging from 12 to 29 years old, among which there were 268 cases elongated at the proximal metaphysis of the tibia, 16 cases at the distal femur and 4 cases at the distal tibia. All of the cases were followed up for 6 to 8 months before clinical evaluation. Results The lower limbs in 288 cases were elongated for 3.0 to 11.5 cm in 24 to 96 days, averaging 47 days, which fulfilled pre-operative plan. In the second week after the operation, new calculus and periosteum formed obviously in the gap between the fractured parts, and in 6 to 8 months bone union was observed at the fractured site in all cases. There was no nerve or blood vessel injury, or non-union of the metaphysis fracture. The functionof the manipulated knee joints and ankle joints recovered well. Conclusion It is a practical and safe surgical option to rectify the shortened lower limbs by closed fracture at the metaphysis, followed by elongation of the fractured bone,without any complication such as non-union or atrophy of manipulated bone, andwith no need of internal fixation or bone grafting.
ObjectiveTo systematically evaluate the effects of closed drainage and simply closed drainage combined with pleurodesis in the treatment spontaneous pneumothorax. MethodsWe searched PubMed, Web of Science, The Cochrane Library, CBM, WanFang Data and CNKI from their inception to December 2nd, 2014, to collect randomized controlled trials (RCTs) of simple closed drainage versus closed drainage combined with pleurodesis in the treatment of spontaneous pneumothorax. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data and evaluated the risk of bias of included studies. Then, RevMan 5.3 software was used for meta-analysis. ResultsA total of 5 RCTs including 499 patients were included. The results of meta-analysis showed that:Compared with the simple closed drainage, the closed drainage combined with pleurodesis was superior in the effective rate of recurrence spontaneous pneumothorax (OR=6.85, 95%CI 3.26 to 14.39, P<0.000 01) and the recurrence rate of primary spontaneous pneumothorax (OR=0.32, 95%CI 0.18 to 0.57, P<0.001). But there were no statistical differences in both groups in the effective rate of primary spontaneous pneumothorax (OR=1.49, 95%CI 0.71 to 3.14, P=0.29), the hospital stays of primary spontaneous pneumothorax (SMD=0.08, 95%CI -0.16 to 0.31, P=0.52), the hospital stays of recurrence spontaneous pneumothorax (SMD=-1.67, 95%CI -3.96 to 0.61, P=0.15), and the duration of drainage of primary spontaneous pneumothorax (SMD=-0.11, 95%CI 0.79 to 0.58, P=0.76). ConclusionCurrent evidence suggests that closed drainage combined with pleurodesis could improve the effective rate of recurrence spontaneous pneumothorax and decrease the recurrence rate of primary spontaneous pneumothorax. Due to limited quantity and quality of included studies, the above conclusion should be validated by more high quality studies.
ObjectiveTo investigate etiology of granulomatous mastitis and it,s conservative treatment method. MethodThe clinical data of 120 patients with granulomatous mastitis given drugs for closed treatment plus massage dredge and ductal lavage from January 2011 to December 2012 in this hospital were analyzed retrospectively. ResultsOne hundred and one cases were cured following conservative treatment for 2 to 8 weeks,19 cases were underwent surgical treatment because of poor outcome.Nine of 101(8.9%) cured patients were relapsed for following-up of 30 to 42 months. ConclusionClosed treatment with drugs,which is effective,could keep patient with granulomatous mastitis from having mastectomy and reduce recurrence.
【Abstract】 Objective To study the influence of close-box and open-box knee prosthesis on postoperative bloodloss in patients undergoing total knee replacement(TKR). Methods From June 2005 to December 2006, 108 atients with primaryknee osteoarthritis were treated with TKR. Closed-box knee prosthesis was used in 54 patients (Group A), including unilateral(Group A1, n =27)and bilateral (Group A2, n =27). There were 7 males and 47 females, aged 41-76 years; and the diseasecourse was 4-16 years. Open-box knee prosthesis was used in 54 patients(Group B), including unilateral (Group B1, n =27)andbilateral(Group B2, n =27). There were 8 males and 46 females, aged from 59-81 years; and the disease course was 8-26 years. Thepostoperative blood loss and perioperative blood loss were compared between groups. Results The postoperative blood losswas (890±352), (1 694±528), (1 068±386) and(2 065±622) mL in groups A1, A2, B1 and B2, respectively. There was no significantdifference between groups A1 and B1(P gt; 0.05). There was significant difference between groups A2 and B2(P lt; 0.05). The totalblood loss was (1 095±329), (2 082±594), (1 274±415) and (2 459±734) mL in groups A1, A2, B1 and B2, respectively. Therewas no significant difference between groups A1 and B1(P gt; 0.05). There was significant difference between groups A2 and B2(P lt; 0.05). Conclusion Closed-box knee prosthesis may play roles on reducing postoperative blood loss. The main influentialfactor for postoperative blood loss is operation techniques which includes reducing operation time and stanching thoroughlyduring operation.
ObjectiveTo evaluate the short-term effectiveness of the short incision and non-end-to-end suturing system in the treatment of acute closed Achilles tendon rupture. MethodsBetween September 2011 and September 2013, 22 patients with acute Achilles tendon rupture were treated with self-designed minimally invasive non-end-to-end suturing system. There were 16 males and 6 females, aged from 22 to 55 years (mean, 32.6 years). The left side was involved in 12 cases and the right side in 10 cases. The causes included sports injury in 16 patients, violent injury in 4 patients, and falling injury in 2 patients. MRI revealed that the distance from the ruptured site to the calcaneal tuberosity ranged from 40 to 70 mm (mean, 35 mm). The duration from injury to surgery ranged from 0.5 to 7 days (mean, 4.2 days). The incision of 4 cm in length was made at the initial point of Achilles tendon, and minimally invasive non-end-to-end suturing system was used to hold the Achilles. The ruptured tendon was sutured with two non-absorbed thread. The limb was fixed with plaster for 6 weeks. ResultsThe incision all healed by first intention without complications of sural nerve damage and infection. All patients were followed up 8-14 months (mean, 11 months). According to the Arner-Lindholm functional score criteria, the results were excellent in 19 cases and good in 3 cases. No Achilles tendon rupture happened again during follow-up. ConclusionThe small incision with non-end-to-end suturing system is an effective operation strategy for treatment of acute Achilles rupture. The patients can do function exercise at early-stage with satisfatory short-term effectiveness.
Objective To evaluate and compare the outcomes of simple closed reduction, selective fragment excision after closed reduction, and emergency fragment excision and reduction in the treatment of Pipkin type I fracture of femoral head associated with posterior dislocation of the hip. Methods Between January 2002 and January 2008, 24 patients with Pipkin type I fracture of the femoral head associated with posterior dislocation of the hip were treated with simple closed reduction (closed reduction group, n=8), with selective fragment excision after closed reduction (selective operation group, n=8), and with emergency fragment excision and reduction (emergency operation group, n=8). In the closed reduction group, there were 6 males and 2 females with an average age of 37.6 years (range, 19-56 years); injuries were caused by traffic accident in 6 cases, by fall ing from height in 1 case, and by crushing in 1 case with a mean disease duration of 3.1 hours (range, 1.0-7.5 hours); and the interval from injury to reduction was (4.00 ± 2.14) hours. In the selective operation group, there were 7 males and 1 female with an average age of 37.3 years (range, 21-59 years); injuries were caused by traffic accident in 7 cases and by fall ing from height in 1 case with a mean disease duration of 3.2 hours (range, 1.0-6.0 hours); and the interval from injury to reduction was (3.90 ± 1.47) hours. In the emergency operation group, there were 5 males and 3 females with an average age of 35.5 years (range, 20-58 years); injuries were caused by traffic accident in 5 cases, by fall ing from height in 1 case, and by crushing in 2 cases with a mean disease duration of 3.3 hours (range, 1.5-6.5 hours); and the interval from injury to open reduction was (5.10 ± 2.04) hours. There was no significant difference in the age, gender, disease duration, and interval from injury to reduction among 3 groups (P gt; 0.05). Results All wounds in selective operation group and emergency operation group healed primarily. All the patients were followed up 24 to 58 months (mean, 38.7 months). According to Thompson-Epstein system, the excellent and good rates were 50.0% (4/8) in the closed reduction group, 87.5% (7/8) in the selective operation group, and 87.5% (7/8) in the emergency operation group at 24 months after operation, showing significant difference among 3 groups (χ2=9.803, P=0.020). Heterotopic ossification was found in 1 case (12.5%) of the closed reduction group, in 4 cases (50.0%) of the selective operation group, and in 4 cases (50.0%) of the emergency operation group, and avascular necrosis of femoral head was found in 2 cases (25.0%) of the closed reduction group; there was no significant difference in compl ications among 3 groups (P gt; 0.05). Conclusion The treatment of Smith-Petersen approach and fragment excision by selective operation or emergency operation has similar outcome, which are better than the treatment of simple closed reduction.
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.
【Abstract】 Objective Through a retrospective study, to observe the cl inical therapeutic effect for closed reductiontreatment of developmental dislocation of the hip (DDH), and to dynamically analyze characteristics of acetabular development after closed reduction in DDH. Methods A total of 100 single side DDH children who were treated by “the treatment mode of closed reduction” from January 2002 to December 2005 were followed up, including 18 males and 82 females, with the average age of 19.4 months (ranging from 7 months to 36 months). Sixty-eight patients had left side dislocation, while 32 had right side dislocation. According to Zionts dislocation grades, 15 cases were degree I, 50 degree II, 26 degree III and 9 degree IV. Adductor tenotomies and skeletal traction were carried out in 74 cases, while direct closed reduction was performed in 26 cases. The four-level functional evaluation criterion was used to assess the cl inical therapeutic effect. Lesional and homeochronous normal hips were paired, and acetabular index (AI) and AI (D/W) of lesional and normal hips, before the reduction and in the 3rd, 6th, 9th and 12th month, respectively, after the reduction, were dynamically measured. Results The total choiceness rate of 100 children was 88.00%. Twelve months after the reduction, lesional AI decreased from (37.17 ± 2.17) º to (27.02 ± 3.54) º, while lesional AI(D/W) increased from 22.06% ± 1.65% to 29.80% ± 3.56%, and the differences among each time-point had statistical significance (P lt; 0.01). Both rates of lesional AI decrease and AI(D/W) increase were obviously faster than those of normal side physiological development (P lt; 0.01). In all durations after 12 months reduction, the rates of lesional AI were (3.22 ± 1.42) º and (3.41 ± 2.03) º in 1 - 3 months and 10 - 12 months , respectively, and the rates of AI(D/W) were 2.69% ± 1.83%and 2.33% ± 1.13%, respectively, and they were obviously faster than the other durations (P lt; 0.01). Both rates of lesional AI decrease and AI(D/W) increase were obviously faster than the homeochronous rate of normal side physiological development in each duration (P lt; 0.01). The rates of lesional AI were (13.71 ± 3.96) º and (11.48 ± 4.15) º in 7 - 12 age group and 13 - 18 age group, respectively, and the rates of AI(D/W) were 9.95% ± 3.81% and 8.28% ± 3.58%, respectively, and they wereobviously faster than the other age groups (P lt; 0.05). Both changes of lesional AI and AI(D/W) were obviously faster than the homeochronous changes of normal side in each age group(P lt; 0.01). Conclusion There are simple operating requirements and fine therapeutic effect of “the treatment mode of closed reduction” . Within 12-month after the closed reduction treatment, the rate of lesional acetabular development is obviously faster than that of normal side physiological development. The cresttime of lesional acetabular development is during 1 - 3 months and 10 - 12 months, and the best treatment time of closed reduction is the age before 18 months.
Objective To investigate the cl inical outcomes of one stage debridement and closed-suction drainage for treatment of infection after lumbar instrumentation. Methods Between June 2002 and March 2008, 12 patients with infection after lumbar instrumentation were treated with one stage debridement and closed-suction drainage, including 9 males and 3females and aging 35-68 years (48.5 years on average). The disease duration varied from 7 days to 183 days (56 days on average). The segments of internal fixation included 7 cases single segment at levels of L4, 5, 4 cases of double segments at levels of L 4, 5, L5, S1 (2 cases), and L3, 4, L4, 5 (2 cases), and 1 case of three segments at levels of L3, 4, L4, 5, L5, S1. Two patients were treated with internal fixator removal. Results The bacterial culture results of intervertebral discs were positive in 8 cases for Staphylococcus aureus and in 3 cases for Enterobacter cloacae, negative in 1 case. Primary healing of incisions were achieved in all cases. Twelve patients were followed up 18-53 months (34.7 months on average). The white blood cell count, erythrocyte sedimentation rate, and C reactive protein significantly decreased after operation, showing significant differences at 15 days after operation when compared with those before operation (P lt; 0.05). No obvious low back pain was observed. Pathological-changed vertebra-space fused. No displacement and breakage of internal fixator occurred; in 2 patients who were given internal fixator removal, no removal of the instrumentation was performed again. The X-ray films showed that the average kyphosis decreased 0.8° at 18 months after operation. At last follow-up, the visual analogue scale score was 2 ± 1, showing significant difference (P lt; 0.05) when compared with that (10 ± 2) before operation. Conclusion One stage debridement and closed-suction drainage therapy is an effective method for treating infection after lumbar instrumentation. The operation is easy and can reduce hospitalization days.
