Objective To explore the effect of " closed-loop rehabilitation”-based digital mirror therapy (MT) on the recovery of upper limb function after stroke. Methods Between December 2017 and April 2018, 90 stroke patients were recruited and randomly assigned to digital MT group (MG) or conventional group (CG), with 45 in each group. Patients in MG received digital MT for 60 minutes and subsequent hand function rehabilitation for 30 minutes, which was a " closed-loop rehabilitation”; moreover, patients in CG received therapeutic exercises, occupational therapy, and hand function rehabilitation for 30 minutes separately (totally 90 minutes). Both interventions were daily provided, 5 days per week and lasting for 4 weeks. Clinical assessments were provided before and after the interventions, including the Fugl-Meyer Assessment Upper Limb (FAM_UL) for motor function evaluation, the Modified Barthel Index (MBI) for the activities of daily life (ADL) evaluation, and the Modified Ashworth Scale (MAS) for the spasticity of wrist extensor/flexor. Results Five patients did not complete the study (3 in MG and 2 in CG), so there were totally 85 subjects analysed in the end. After 4-week interventions, significant improvements of FMA_UL scores (Pre: MG, 25.86±17.41; CG, 21.71±15.60. Post: MG, 33.43±17.08; CG, 26.48±16.47) and MBI scores (Pre: MG, 66.62±21.73; CG, 59.14±21.58. Post: MG, 84.62±15.06; CG, 71.10±19.95) were found in both groups; moreover, higher scores of FMA_UL and MBI were investigated in MG comparing with CG after interventions. However, there were no significantly differences in MAS. Conclusions The " closed-loop rehabilitation”-based digital MT can improve the motor function of upper limb and the ability of ADL in patients with stroke. Moreover, it is more effective than conventional treatments.
OBJECTIVE: To study the management of extensive closed internal degloving injury (CIDI). METHODS: From September 1987 to October 1999, 18 cases of CIDI were retrospectively reviewed. Of 18 cases, there were 7 cases in thigh, 6 cases in legs and 5 cases in pelvis, ranging from 15 cm x 12 cm to 38 cm x 25 cm in size. Various managements were adopted according to the severity of the injury, including vacuum drainage and adjuvant compression in 5 cases, regrafting of defatting fenestrated full-thickness skin by non-resection in 8 cases, and skin grafting with transfer of myocutaneous flap in 5 cases. Among them, there were 11 cases of bone and articular fixation or repair, 4 cases of principal vessels repair. All of the cases were evaluated clinically and followed up for 6 months to 3 years. RESULTS: In the 8 cases repaired by regrafting of defatting fenestrated full-thickness skin, only one case of skin necrosis, 5 cm x 2 cm in size, recovered after skin grafting; the others healed well. All of the patients recovered normal life and had normal limbs. CONCLUSION: It’s crucial to make a careful assessment about the injury severity of CIDI, to stress on importance of management of both CIDI and deep injury, and to choose proper options after comprehensive assessment of the injury.
ObjectiveTo evaluate the clinical efficacy of central venous catheter closed drainage of pleural cavity combined with negative pressure suction in the treatment of spontaneous pneumothorax.
MethodsThe randomized controlled trials(RCTs) on central venous catheter closed drainage of pleural cavity combined with negative pressure suction in the treatment of spontaneous pneumothorax were searched in PubMed, OVID, CNKI, Wangfang database, Super Star Digital Library, CMB, Baidu and Google search engines. The searching time was from the time of building database to September 15, 2014. Two searchers selected studies based on the included criteria strictly. The quality of RCTs was appraised by the criteria of Cochrane Collaboration. RevMan5.3 software was used for data analysis and management.
ResultsA total of 18 RCTs including 1 549 patients were identified. There were no statistical differences in time of lung recruitment (SMD=0.01 and 95%CI -0.23 to 0.25, P=0.95), time of hospital stay (SMD=-0.42, 95%CI -1.81 to 0.97, P=0.55), curative resection rate (RR=1.04 and 95%CI 1.00 to 1.08, P=0.07) between the two groups. The rate of complications in the central venous catheter group was less than that in the conventional pleural cavity closed drainage group with a statistical difference (RR=0.31, 95%CI 0.23 to 0.43, P<0.000 01).
ConclusionThe treatment of central venous catheter closed drainage of pleural cavity combined with negative pressure suction for spontaneous pneumothorax is a simple and safe operation. However, the quality of studies included is not high and some sample size is small. RCTs with large sample of high quality are still needed for further confirmation.
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.
【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.
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.
Objective
To describe a surgical device for closed reduction of tibial fracture and investigate its clinical effectiveness.
Methods
Between June 2010 and December 2012, 24 cases of tibial fractures were treated with intramedullary nailing using a surgical device for closed reduction. There were 18 males and 6 females with an average age of 40 years (range, 20-64 years). All fractures were closed. There were 3 proximal third fractures, 12 middle third fractures, and 9 distal third fractures. According to AO classification, 12 cases were classified as type A, 8 cases as type B, and 4 cases as type C. The mean time between injury and operation was 3 days (range, 1-12 days). The intraoperative fluoroscopy frequency to confirm closed reduction and guide wire passing the fracture site, and the duration between fracture reduction and nail insertion were recorded. The injured limb alignment and fracture angular deformity were measured as described by Freedman et al. The fuction of affected limb was estimated by Johner-Wruhs criteria.
Results
Closed reduction was successfully performed in 24 patients. The mean fluoroscopy frequency to confirm closed reduction was 3 (range, 2-5). The fluoroscopy frequency to confirm guide wire passing the fracture site was 2. The mean duration between fracture reduction and nail insertion was 30 minutes (range, 20-42 minutes). No intraoperative or postoperative complication occurred, such as infection, vessel and nerve injuries. All incisions healed by first intention. Seventeen patients were followed up 6-16 months (mean, 10 months). Radiographic evidence showed that bridging callous was observed at 2-4 months (mean, 2.5 months). The injured limb alignment was normal on anteroposterial and lateral radiographs at 5 months postoperatively, no malalignment and obvious angular deformity was observed. The internal fixator had good position. According to Johner-Wruhs criteria for evaluation of the affected limb function, the results were excellent in 12 cases and good in 5 cases with an excellent and good rate of 100%.
Conclusion
The surgical device for closed reduction of tibial fracture is simple and easy to use, and has good effectiveness combined with intramedullary nailing.
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.
