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.
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.
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.
Objective To investigate the surgical technique and effectiveness of volar locking plates for senile delayed distal radius fractures. Methods Between October 2014 and September 2015, 25 cases of delayed distal radius fractures were treated by volar locking plates. There were 3 males and 22 females with an average age of 73 years (range, 65-87 years). Injury was caused by tumble in 19 cases and by traffic accident in 6 cases. All the cases had closed fracture. According to the AO classification, 10 cases were rated as type A2, 7 cases as type A3, 3 cases as type B3, and 5 cases as type C1. The manual reduction and plaster immobilization were performed in 18 cases first, but reduction failed; no treatment was given in 7 cases before surgery. The time from injury to surgery was from 33 to 126 days (mean, 61 days). Preoperatively, the volar tilting angle was (–16.0±3.1)°; the ulnar inclining angle was (10.8±7.0)°; the radial shortening was (11.2±3.6) mm; the wrist range of motion was (41.0±7.5)° in flexion and was (42.0±6.3)° in extension; and the grip strength was 33.0%±3.1% of normal side. Results All incisions healed primarily, and no postoperative complication occurred. The patients were followed up 1-1.5 years (mean, 1.3 years). The X-ray films showed that fracture union was achieved in all the patients, with the mean healing time of 9.2 weeks (range, 8-12 weeks); the displacement of the articular surface was less than 1 mm. At last follow-up, the volar tilting angle was (13.1±3.2)°; the ulnar inclining angle was (21.9±4.6)°; the radial shortening was (2.0±1.1) mm; the wrist range of motion was (52.0±11.7)° in flexion and was (65.0±4.8)° in extension; and the grip strength was 84.0%±4.2% of normal side; all showed significant difference when compared with preoperative ones (P<0.05). According to the Gartland and Werley score, the results were excellent in 15 cases, good in 6 cases, fair in 2 cases, and poor in 2 cases at last follow-up; the excellent and good rate was 84%. Conclusion By the good design of the volar locking plate and the command of surgical techniques, good effectiveness can be achieved in the treatment of senile delayed distal radius fracture.
Objective To determine the cl inical results of locking plate system in the treatment of distal radial fractures. Methods From May 2004 to November 2006, 75 patients were treated with 2.4 mm locking plate system. There were 41 males and 34 females, with a mean age of 51 years old (range, 13-82 years old). The locations were left side in 34 casesand right side in 41 cases. The cause of injury was a low energy fall in 49 cases, fall ing from height in 14 cases, traffic accident in 6 cases and sports injuries in 6 cases. All patients were diagnosed as having closed fracture. According to Müller-AO classification, there were 14 cases(18.7%) of type A, 5 cases(6.7%) of type B, and 56 cases(74.6%) of type C. The time from injury to operation was 5 hours to 27 days (mean 6 days). Results A total of 75 patients were followed up at 3 months, 71 patients at 6 months, 68 patients at 1 year and 51 patients at 2 years. Heal ing by first intention of incision was achieved in 73 cases, and infection occurred in 2 cases. Fracture reduction failed at 1 month, 3 months and 6 months in 1 case, respectively; 1 case received plaster fixation and 2 cases received re-fixation and autograft of il ium; and fracture healed in 3 cases at last follow-up. Two patients complained of skin numbness at site of superficial branch of radial nerve after 1 day, 1 patient had wound pain after operation, and 1 patient had infection of tendon at 3 days and 5 days in 1 case respectively. At last follow-up, the ranges of motion of wrist joint were (80 ± 9)° for pronation, (86 ± 7)° for supination, (57 ± 10)° for dorsal flexion, (51 ± 13)° for palmar flexion, (18 ± 7)° for radial incl ination, and (28 ± 7)° for ulnar deviation. According to modified Green scoring, the results were excellent in 66 cases, good in 6 cases and poor in 3 cases. At last follow-up, according to Knirk criterion for osteoarthritis, there were 22 cases of grade I and 5 cases of grade II, and all were classified as type C. Conclusion Internal fixation of distal radial fractures with 2.4 mm locking plate system provided a stable fixation with good cl inical outcomes.
ObjectiveTo compare the effectiveness of minimally invasive percutaneous internal fixation and traditional open reduction via Henry approach and internal fixation in the treatment of unstable distal radial fractures.MethodsFifty-six patients with unstable distal radial fractures that met the selection criteria between October 2013 and December 2014 were randomly divided into minimally invasive group (26 cases) and traditional group (30 cases). They were treated with oblique T-shaped locking plate internal fixation via minimally invasive percutaneous approach or traditional Henry approach. There was no significant difference in gender, age, side, causes of injury, fracture classification, and time from injury to operation between 2 groups (P>0.05). The length of incision, operation time, intraoperative blood loss, hospitalization time, and fracture healing time were recorded in 2 groups. The difference of the length of the radial styloid process, the volar tilting angle, and the ulnar inclining angle between at 3 months postoperatively and preoperation were compared between 2 groups. The visual analogue scale (VAS) score, the percentage of the lateral wrist flexion and extension range, forearm rotation, and the hand grip strength (recorded as FS%, FR%, and HG% , respectively) were compared between 2 groups at 4 weeks and 3 months postoperatively. The wrist function was evaluated through the disability of arm-shoulder-hand (DASH) scores at 3 months postoperatively.ResultsThe length of incision, operation time, intraoperative blood loss, and hospitalization time in minimally invasive group were significantly less than those in traditional group (P<0.05). The incisions of 2 groups were all achieved primary healing. All patients were followed up 10-16 months (mean, 12.6 months). There was no radial artery injury, screw too long, or screw entering the joint space. In minimally invasive group, 1 patient had the symptoms of median nerve irritation after operation, and recovered completely at 1 month; in traditional group, there were 2 cases of tendon irritation after operation. There was no significant difference in the fracture healing time, the difference of the length of the radial styloid process, the volar tilting angle, and the ulnar inclining angle between at 3 months postoperatively and preoperation between 2 groups (P>0.05). At 4 weeks after operation, the VAS score in minimally invasive group was significantly less than that in traditional group, and the FS%, FR%, and HG% were significantly higher than those in traditional group (P<0.05). There was no significant difference in above indicators between 2 groups at 3 months after operation (P>0.05). The DASH score in minimally invasive group was significantly less than that in traditional group at 3 months after operation (t=–5.308, P=0.000). The patient’s aesthetic evaluation of postoperative wound in minimally invasive group was better than in traditional group.ConclusionFor treatment of unstable distal radial fractures, the metacarpal minimally invasive internal fixation has the advantages of smaller wound, incisional concealment, and quicker recovery of wrist joint.
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.
