  • EFFECT OF ASSOCIATED ULNAR STYLOID FRACTURE ON WRIST FUNCTION AFTER DISTAL RADIUS FRACTURE

    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.

  • A COMPARISON OF OPEN REDUCTION AND CLOSED REDUCTION IN TREATING DISTAL RADIUS FRACTURES IN ELDERLY PATIENTS

    Objective To discuss the relationship between recovery of anatomical integrity and functional outcome in elderly patients with distal radius fractures by comparing the effects of open reduction and closed reduction. Methods The cl inical data were retrospectively analyzed from 78 elderly patients with distal radius fractures treating with nonoperation andoperation from February 2005 to March 2009. Thirty-seven patients underwent closed reduction and spl intlet fixation or cast appl ication (non-operation group), and forty-one patients underwent open reduction and internal fixation (operation group). In non-operation group, there were 15 males and 22 females with an average age of 73 years (60-83 years). According to the AO classification system for fracture, there were 8 cases of type A2, 7 cases of type A3, 7 cases of type B1, 4 cases of type B2, 2 cases of type B3, 4 cases of type C1, 2 cases of type C2, and 3 cases of type C3. The time from injury to admission was between 30 minutes and 3 days with a mean time of 1 day. In operation group, there were 18 males and 23 females with an average age of 71 years (62-80 years). According to the AO classification system for fracture, there were 5 cases of type A2, 7 cases of type A3, 7 cases of type B1, 6 cases of type B2, 3 cases of type B3, 4 cases of type C1, 5 cases of type C2, and 4 cases of type C3. The time from injury to admission was between 30 minutes and 7 days with a mean time of 1 day. There were no significant differences (P gt; 0.05) in sex, age, disease course and fracture classification between two groups. Results All incisions obtained heal ing by first intention after operation in operation group. All patients were followed up for 9-36 months (20 months on average). Fracture heal ing was achieved within 8 to 15 weeks, with an average of 11 weeks. There were no significant differences (P gt; 0.05) in fracture heal ing time between non-operation group [(10.8 ± 2.0) weeks] and operation group [(11.7 ± 2.5) weeks]. At last follow-up, thepalmar tilt angle was (5.6 ± 2.0)° and (8.6 ± 3.0)°, the radial incl ination angle was (19.1 ± 4.9)° and (21.8 ± 2.0)°, and the radial length was (8.3 ± 1.3) mm and (10.4 ± 1.4) mm in non-operation group and operation group, respectively; showing significant differences (P lt; 0.05) between two groups. According to the Gartland-Werley score, the results were excellent in 9 cases, good in 21 cases, fair in 5 cases, and poor in 2 cases in non-operation group, the excellent and good rate was 81.1%; in operation group, the results were excellent in 13 cases, good in 25 cases, fair in 2 cases, and poor in 1 case, the excellent and good rate was 92.7%, showing no significant difference (P gt; 0.05) between two groups. There were no significant differences (P gt; 0.05) in flexion and extension activity of wrist, radioulnar partial activity, pronation-supination activity, grip and pinch strength between two groups. Conclusion Open reduction and closed reduction can achieve satisfactory functional outcomes, but closed reduction was inferior to open reduction in anatomic reduction for treating distal radius fractures in elderly patients.

  • LESS INVASIVE LEVERAGE REDUCTION WITH EXTERNAL FIXATOR SUPPORTED AND BONE GRAFT FORTREATMENT OF UNSTABLE FRACTURES OF DISTAL RADIUS

    【Abstract】 Objective To assess the results of treatment of unstable distal radius fractures with leverage reductionand bone graft assisted by external fixators. Methods From September 2005 to May 2007, 27 cases of unstable distal radius fractures were treated by leverage reduction and bone graft, meanwhile assisted by external fixators. The cases included 16 males and 11 females, aged from 18 to 69 years with an average of 49. 3 years. Fractures were caused by fall ing in 19 cases, crash from high place in 1 case, traffic accident in 6 cases, and obtuse strike directly in 1 case, which were all closed fresh bone fractures. According to the standard of AO, all cases were classified as type C1 in 13 cases, type C2 in 11 cases, and type C3 in 3 cases. The palmar incl inination was from - 38° to 10°(mean - 12.2°); the ulnar deviation angle was from 6° to 30° (mean 19. 1°) before operations. The operations were performed from 1 to 3 days after injuries. The function of the carpal joints and the boneheal ing conditions were evaluated after operations. Results All cases were followed up for 4-24 months(mean 13. 1 months). No compl ications such as pin loosening, dislocation of fixators, injury of blood vessels and radial nerves, pin track infections occurred. According to Mcbride scoring, the results were excellent in 10 cases, good in 13 cases, fair in 3 cases and poor in 1 case, the excellent and good rate being 85. 2%. One case had traumatic arthritis and 1 case had wrist joint stiffness. All achieved fractures uniton 8-10 weeks (mean 9.3 weeks) after operations. The palmar incl inination angle was from 0° to 20° (mean 13. 4°); the ulnar deviation angle was from 10° to 33° (mean 22. 1°) after operations. Conclusion Treatment of unstable fractures of the distal radius by use of leverage reduction and bone graft with external fixator offers many advantages, such as simple operation, satisfactory reduction, rigid fixation, excellent function and lower incidence rate of traumatic arthritis.

  • COMPARISON BETWEEN VOLAR AND DORSAL PLATE POSITIONS IN THE TREATMENT OF UNSTABLEFRACTURE OF DISTAL RADIUS

    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.

  • TREATMENT OF DISTAL RADIUS FRACTURE BY COMBINATION OF EXTERNAL FIXATOR AND VOLAR APPROACH FIXATION

    Objective To investigate the operative indication and clinical efficacy of combination of external fixator and volar approach fixation in treatingdistal radius fracture. Methods From March 2000 to March 2005, 28 patients with distal radius fracture were treated with combination of external fixator and volar approach fixation. Dorsal external fixator was used to maintain wrist in functional position, combinated volar plate or Kirschner wire fixation after reduction was achieved. Bone graft was necessary if there were severe comminuted cortical bone or compress of cancellous bone. Of 28 patients, there were 21 males and 7 females, aging from 1854 years with a median age of 41 years. The locations were the left side in 4 cases and the right side in 24 cases. According to typing criterion for AO, 18 cases were classified as C2 and 10 cases as C3. One case wasaccompanied with dislocation of lunate bone. Results Among 28 patients, 24 were followed up for an average of 8.5 months. The anatomical relationship of their wristjoint were reestablished and retained. Overall good to excellent results were achieved in 87%, excellent in 16 cases, good in 5 cases and fair in 3 cases. Conclusion A combination of external fixator and volar approach fixation is an effective method of treating fractures of the distal radius,because distal radius fracture is unstable or difficult to close reduction. Volarfixation can avoid operative complication, and external fixator can obtain satisfactory reduction and function.

  • Effectiveness and Safety of External Fixation versus Open Reduction and Internal Fixation for the Adults’ Unstable Distal Radius Fractures: A Systematic Review

    Objective To evaluate the effectiveness and safety of external fixation (EF) and open reduction and internal fixation (ORIF) for unstable distal radius fractures in adults. Methods We searched MEDLINE (1966 to September 2008), Cochrane Central register of controlled Trials (The Cochrane Library, Issue 3, 2008), EMbase (1974 to September 2008), CBM, CNKI, and collected randomized controlled trials (RCTs) of EF and ORIF for unstable distal radius fractures in adults. The quality of the included studies was critically assessed and data analyses were performed with the Cochrane Collaboration’s RevMan 5.0 software. Results Seven RCTs involving 634 patients were included, of which 269 were in EF group, and 293 were in ORIF group. Only 1 study had relative high quality, all the others had some limitation in randomization, blinding, and allocation concealment. The results of meta-analyses showed that, 1) about the effectiveness: according to the Gartland and Werley grade standard, the ORIF group was better than the EF group with statistic difference (RR=1.50, 95%CI 1.11 to 2.03, P=0.008); because of the original studies did not offer the detailed data including pad strength, grip strength, flexion-extension, radial deviation, and ulnar deviation, we only processed a descriptive analysis; and 2) about complications: the infection rate of the pin track was higher in the EF group than that in the ORIF group with statistic difference (RR=0.24, 95%CI 0.08 to 0.76, P=0.02); but there were no differences between the two groups in reflex sympathetic dystrophy (RSD) (RR=0.88, 95%CI 0.30 to 2.56, P=0.82), extensor tendon rupture (RR=3.93, 95%CI 0.45 to 34.62, P=0.22), and compartment syndrome (RR=3.13, 95%CI 0.51 to 19.09, P=0.22). Conclusions Compared with EF, ORIF is much better based on Gartland and Werley grade standard, and causes much less infection. Because of the limited quality and quantity of the included studies, more proofs are required from more RCTs with large sample.

  • EFFECTIVENESS COMPARISON OF EXTERNAL FIXATION AND VOLAR LOCKING COMPRESSION PLATE IN TREATMENT OF DISTAL RADIUS FRACTURES OF TYPE C

    ObjectiveTo compare the effectiveness of external fixation and volar locking compression plate in the treatment of distal radius fractures of type C. MethodsBetween March 2012 and March 2013, 122 patients with distal radius fractures of type C were enrolled in the prospective randomized study. Fractures were treated by external fixation in 61 patients (external fixation group) and by open reduction and internal fixation using a volar locking compression plate in 61 patients (plate group). There was no significant difference in age, gender, fracture side, weight, height, body mass index, fracture type, and interval of injury and operation between 2 groups (P>0.05). The blood loss, operation time, hospitalization days, fracture union time, wrist function, and complications were compared between 2 groups. And the quality of reduction was observed, including volar tilting angle, ulnar deviation, radial height, and articular reduction. ResultsThe blood loss, operation time, and hospitalization days in plate group were significantly higher than those in external fixation group (P<0.05). All of the patients in both groups were followed up 12-28 months. Postoperative complications occurred in 4 patients (6.6%) of external fixation group (pin tract infection in 2 cases and radial nerve neuritis in 2 cases) and in 5 patients (8.2%) of plate group (wound infection in 1 case, carpal tunnel syndrome in 2 cases, and tendon rupture in 2 cases), showing no significant difference between 2 groups (P=0.500). The X-ray films showed fracture healing in all patients of 2 groups; the union time of plate group was significantly longer than that of external fixation group (P<0.05). At last follow-up, there was no significant difference in ulnar deviation and radial height between 2 groups (P>0.05), but the volar tilting angle of plate group was significantly larger than that of external fixation group (P<0.05). There was no significant difference in wrist function and articular reduction between 2 groups (P>0.05). ConclusionFor distal radius fractures of type C, the use of external fixation or volar locking compression plate can obtain satisfactory clinical outcomes, but the external fixation has the advantages of less invasion, shorter hospitalization days, minor complications, and faster fracture union.

  • Influence of Associated Ulnar Styloid Fracture on Prognosis of Distal Radius Fracture

    ObjectiveTo systematically review the effects of associated ulnar styloid fracture on the prognosis of distal radius fracture. MethodsDatabases including PubMed, EMbase, The Cochrane Library (Issue 5 2013), CNKI, CBM and WanFang Data were searched up to May 2013 for collecting cohort studies about the effects of associated ulnar styloid fracture on the prognosis of distal radius fracture. According to the inclusion and exclusion criteria, related cohort studies were screened, data were extracted and cross-checked, and quality of included studies was independently evaluated by two reviewers. Meta-analysis was then conducted using RevMan 5.2 software. ResultsA total of 9 studies involving 1 020 patients were included. The results of meta-analysis showed that there was no significant difference in GartlandWerley score between patients with ulnar styloid fracture or not. Statistical significant difference was found in DASH score between the two groups (MD=2.71, 95% CI 0.26 to 5.16, P=0.03), which indicated that patients with ulnar styloid fracture got higher score in DASH score. ConclusionCurrent evidence shows that ulnar styloid fracture may affect the prognosis of patients with distal radius fracture. Due to the quality and quantity limitation of the included studies, the above conclusion needs to be further verified by more high quality studies in future.

  • Ilizarov technique for treatment of distal radius deformity and bone defect after trauma

    ObjectiveTo investigate the effectiveness on the distal radius deformity and bone defect after trauma by using Ilizarov external fixator.MethodsThe clinical data of 9 patients of post-traumatic distal radius deformity with bone defect treated by Ilizarov technique between January 2012 and December 2016 were retrospectively analyzed. There were 7 males and 2 females with an average age of 25.6 years (range, 11-46 years). Of the 9 cases, 4 were radial baseball hand deformity with large bone defect, 4 were short deformity of distal radius, 1 was distal radius deformity with radial deflection and pronation deformity, all with distal dislocation of the distant radial-ulnar joint. The time from injury to operation was 6 months to 6.2 years (mean, 1.5 years). The bone defect was 1.4-6.8 cm (mean, 3.6 cm). After complete debridement, the forearm was fixed with Ilizarov external fixator. At 7 days after operation, bone transport or bone lengthening was performed at the rate of 0.8-1 mm/d, 4 times a day, the deformity was slowly corrected and the bone defect was repaired. According to the loss of palmar tilt angle and ulnar tilt angle measured before operation, the position of distal radial articular surface was gradually adjusted in the course of moving or prolonging, so as to restore palmar tilt angle and ulnar tilt angle as far as possible.ResultsAll wounds healed by first intention and no leakage or rupture occurred. All the 9 patients were followed up 15-36 months (mean, 23 months). All the radius defects healed and the distal deformity was corrected, the healing time was 92.4-138.6 days (mean, 104.7 days); the external fixation index was 32.6-51.1 days/cm (mean, 40.2 days/cm). After 2 months of external fixator removal, the wrist joint flexion was (42.6±3.1)°, the wrist dorsum extension was (48.5±4.7)°, the palm inclination angle was (11.5±1.3)°, and the ulnar deviation angle was (21.2±3.7)°; the elbow flexion was (128.2±6.4)°, the elbow extension was (3.2±2.1)°, the forearm pronation was (71.5±4.3)°, and the forearm rotation was (38.2±6.5)°; the wrist and elbow joint extension and forearm rotation were significantly improved when compared with preoperative values (P<0.05). At last follow-up, wrist function was assessed according to Gartland-Werley standard, the results were excellent in 3 cases, good in 5 cases, and fair in 1 case. Four cases had pinhole infection, and were cured after anti inflammatory dressing change or replacement of needles; 3 cases did not heal at the bone junction, and were healed after bone grafting; 4 cases deviated from the radial force line, and the deformity was corrected after adjusting the needle.ConclusionIlizarov technique can correct deformity and reconstruct bone defect of the post-traumatic distal radius simultaneously, so it is a good method to treat this kind of disease.

  • Effectiveness analysis of distal radius microplate locking plate for treatment of displaced fracture of medial clavicle

    ObjectiveTo investigate and evaluate the effectiveness of the distal radius microplate locking plate for the treatment of displaced fracture of medial clavicle.MethodsBetween January 2013 and June 2017, 18 cases of obvious displaced fracture of medial clavicle were treated with distal radius microlocking plate. There were 10 males and 8 females, with an average age of 51.4 years (range, 18-88 years). Causes of injury included traffic accident injury in 15 cases, heavy object injury in 3 cases; all of them were closed injury. According to Edinburgh classification, 15 cases were ⅠB1 type and 3 cases were ⅠB2 type. Fracture displacement was 12-21 mm (mean, 16.3 mm). The time from injury to operation was 3-7 days (mean, 4.3 days). After operation, the clinical healing and complications of fracture were observed, and shoulder function was evaluated according to Rockwood’s scoring criteria.ResultsNo incisional infection, neurovascular injury, or other early complications occurred. All 18 patients were followed up 8-15 months (mean, 12 months). All fractures reached clinical osseous union, and the healing time was 8-24 weeks (mean, 16.6 weeks). Postoperative plate loosening occurred in 1 case, which was removed surgically, while other patients did not suffer from complications such as bone nonunion, displacement, internal fixator loosening, and loss of reduction. At last follow-up, according to Rockwood’s scoring criteria, the results were excellent in 12 cases and good in 6 cases.ConclusionThe distal radius microplate locking plate is effective for the treatment of displaced medial clavicle fracture, which has few complications, and is feasible for early functional exercise, and is helpful for the recovery of shoulder joint function.
