We present 2 cases showing that flexor pollicis longus and flexor digitorum profundus index injury can occur after placement of 2 commonly used locked volar plates. In contrast with the literature, the radii healed in an anatomic position without plate lift-off. The patients presented 6 and 8 months after surgery with new onset of radial wrist pain and tenderness at the site of the plate and absence or weakness of the flexor pollicis longus. In both cases, the plate was positioned anterior to the distal radial rim on the lateral radiograph. We suggest close follow-up of all fractures in which the distal end of the plate is anterior to the radial rim and removal of hardware if symptoms suggest tendon irritation. 相似文献

Results of dorsal or volar plate fixation of AO type C3 distal radius fractures: a retrospective study 总被引:1,自引:0,他引:1
PURPOSE: The aim of this study was to define the outcome after dorsal or volar plating of Association for Osteosynthesis (AO) type C3 distal radius fractures based on the fracture morphology. METHODS: Twenty-nine patients with AO type C3 distal radius fractures were surgically managed between 1996 and 2005. Group 1 (n = 15) had volar plating. Group 2 (n = 14) had dorsal plating. Outcomes were evaluated at an average of 22 months after surgery. Statistical analysis was performed using the Wilcoxon test and chi-square test. RESULTS: No significant differences were seen for the scores of Gartland and Werley, Castaing, Stewart I and II, Green and O'Brien, and Disability of the Arm, Shoulder and Hand between the 2 groups. The visual and verbal pain analog scales did not show significant differences between the 2 groups. Radiology analysis showed significant difference in comparison with the contralateral side in terms of dorsopalmar inclination (3 degrees +/- 3) and distal radioulnar joint angle (98 degrees +/- 8) for the patients in group 1, whereas there were no significant differences in group 2. The development of radiographic post-traumatic arthritis was significant in both groups. Significant functional differences were seen for flexion (45 degrees +/- 15) and hand span (20 cm +/- 2) in group 1 as well as for extension (37 degrees +/- 19), flexion (42 degrees +/- 12), and radial deviation (16 degrees +/- 10) in group 2. We found more complications after dorsal plate osteosynthesis than after volar plate osteosynthesis. CONCLUSIONS: This study shows satisfactory functional and subjective outcome results in both groups. Group 1 had non-significant better functional results than group 2, whereas both groups showed good to very good radiology results. 相似文献

Background:
Fractures of distal radius are common injury in all age groups. Cast treatment with or without close reduction is a viable option. However, the results are often unsatisfactory with restricted function. The open reduction and internal fixation often results in extensive soft tissue dissection and associated high rates of infect and delayed/nonunion. The distractor/external fixator have reported good functional and anatomical results but the incidence of pin traction infection nerve injury and cosmedic deformity are high. We introduced a modified operative technique for minimally invasive plate osteosynthesis (MIPO) for distal radial fracture and evaluated the functional outcomes and complications.Materials and Methods:
22 distal radial fractures (10 left, 12 right) were treated using the MIPO technique and two small incisions with a palmar locking plate from August 2009 to August 2010. The wrist function was assessed according to Dienst wrist rating system, and postoperative complications were recorded.Results:
According to Dienst wrist rating system, 13 patients showed excellent results, 6 cases showed good results and 3 patients had moderate results. No patient had poor results. Thus, the excellent and good rate was 86.4%. One patient had anesthesia in the thenar eminence and this symptom disappeared after 3 months. One patient had delayed healing in the proximal wrist crease. Two patients had mild pain on the ulnar side of the wrist and two patients had limited wrist joint function.Conclusion:
The MIPO technique by using two small palmar incisions is safe and effective for treatment of distal radial fractures. 相似文献7.

Subcapital ulnar fractures in association with distal radius fractures in elderly patients increase instability and pose a treatment challenge. Fixation of the ulnar fracture with traditional implants is difficult due to the subcutaneous location, comminution, and osteoporosis. We describe an intrafocal pin plate that provides fixation by a locking plate on the distal ulna and intramedullary fixation within the shaft. The low profile and percutaneous technique make this device a useful alternative for treatment of subcapital ulna fractures in the elderly. 相似文献

Background:
Distal radius fractures are one of the the most common adult fractures encountered during the clinical practice of an orthopedic surgeon.1,2 Although several methods of treatment are suggested for these fractures, there are still controversies about the best treatment approach in the literature. Volar plating of distal radius fracture is a method of treatment which has become increasingly popular. One of the complications of this technique is flexor tendon rupture. The purpose of this study was to evaluate the protectiveness of complete repair of pronator quadratus muscle against flexor tendon rupture.Materials and Methods:
From September 2010 to September 2012, a consecutive series of 157 patients who were younger than 60 years with unstable distal radius fractures were included in the study. A standard volar approach to the distal radius was carried out. The radial and distal ends of pronator quadratus muscle were meticulously elevated from the radius and after volar plate fixation of the fracture, pronator quadratus muscle was restored to its normal insertion. We achieved full coverage of the plate with this muscle and followed the patients postoperatively.Results:
A total of 135 patients were studied. The mean age of patients was 34 ± 10 years (range 20-60 years). One 55-year-old diabetic female patient with flexor tendon rupture was identified. The flexor pollicis longus tendon had ruptured 16 months after surgery.Conclusions:
Pronator quadratus repair should be done in distal radius fracture to protect flexor tendons. 相似文献12.
目的比较应用外固定支架与锁定钢板内固定治疗桡骨远端C型骨折的疗效。方法 48例桡骨远端C型骨折的患者按手术方式不同分为外固定组(采用闭合复位外固定支架,24例)和内固定组(采用切开复位锁定钢板内固定,24例),比较两组患者术中出血量、手术时间、住院时间、骨折愈合时间、术后腕关节功能。结果 48例获得随访,时间6~24(13.19±4.31)个月。术中出血量、手术时间、住院时间、骨折愈合时间外固定组均少(短)于内固定组,差异均有统计学意义(P0.05)。术后影像学在掌倾角、尺偏角:C1型骨折两种治疗方法比较差异无统计学意义(P0.05);C2骨折内固定组优于外固定组,差异有统计学意义(P0.05);C3型骨折外固定组优于内固定组,差异有统计学意义(P0.05)。结论外固定支架与锁定钢板内固定治疗桡骨远端骨折C型骨折均可获得良好的临床疗效。在术后24周影像学比较中:C2型骨折锁定钢板内固定治疗在影像学上有更好的掌倾角和尺偏角,更有利于关节功能恢复;C3型骨折外固定支架具有更好的牵张力,更能有效避免桡骨远端关节面继发性塌陷。外固定支架治疗创伤较小,有利于术后腕关节功能恢复。 相似文献

Contrary to general belief, arthroscopic assisted reduction in distal radius fractures can be done in an expeditious manner and with minimal consumption of operating room resources. This article presents the steps for a pleasant arthroscopic experience in detail. The technique proposed combines the benefits of rigid fixation with volar locking plates (for the extra-articular component) and arthroscopic control of the reduction (for the articular component). It is important that the operation be carried out using the dry arthroscopic technique. However, arthroscopy is just an addition to conventional methods. Thorough knowledge of and facility with classic techniques of distal radius fracture treatment is essential for a good result. 相似文献

The AO/ASIF Titanium Pi Plate has been developed for dorsal plating of fractures of the distal radius. It is designed by reflection of the anatomy, to ensure stability of the angle using a juxtaarticular band and to minimize tissue reaction by low profile design. The aim of this study was to evaluate the subjective and objective outcome of 61 consecutively operated patients after a minimum of 12 months (12-29 months) postoperatively. There were 3 A2, 23 A3, 1 B1, 12 C1 and 22 C2 fractures (AO-Classification). The subjective results were good to very good. The range of motion showed over 80% compared to the uninjured side. Overall, there were no ruptures of tendons and 18% irritations. Extension, ulnar abduction and force were significantly better in patients in which the plate has been removed. In this collective the tendon irritations were only 3.8%.With the AO/ASIF Pi Plate good subjective and objective results can be achieved. The indication for removal of the plate should be given generously. 相似文献
