The clinical and radiological outcomes of 25 surgically treated fractures of the proximal third of the fifth metacarpal were retrospectively analysed. Many different methods of osteosynthesis were used. At follow-up after a mean of 3.3 years, 15 of 25 patients had no pain. Most patients regained a nearly full range of motion in the adjacent joints and more than 90% of the contralateral grip strength. X-ray signs of degenerative arthritis in the metacarpohamate joint were observed in 10 of 25 patients. Pain was found to be directly correlated with the presence of degenerative changes. 相似文献

Purpose: To evaluate the diagnostic accuracy of high-resolution contrast-enhanced magnetic resonance angiography (CE-MRA) of the supra-aortic arteries using the CareBolus technique. Digital subtraction angiography was the standard of reference. Material and Methods: Fifty consecutive patients with suspected internal carotid artery stenosis underwent CE-MRA and digital subtraction angiography. CE-MRA was performed on a 1.5-T superconducting scanner with the CareBolus technique. CareBolus combines a nearly real-time 2D-FLASH (fast low angle shot) sequence for fluoroscopic triggering and a high-resolution 3D-FLASH with elliptical centric view order for the angiographic pulse sequence (6.0/2.16 ms [TR/TE], 30° flip angle, 30.98 s acquisition time, 0.88 mm effective (interpolated) partition thickness and a 160×512 matrix). Intra-arterial digital subtraction angiography and CE-MRA studies were evaluated independently by four blinded readers. Internal carotid artery stenoses were graded according to the NASCET criteria. Results: CE-MRA had an accuracy of 92.53%, a sensitivity of 95.64%, and a specificity of 90.39% for the identification of carotid artery stenoses ≥70% (grade 3). Image quality for suppression of stationary tissue and venous contrast was good, but was reduced in five cases due to patient motion. Conclusion: The CareBolus technique is a useful non-invasive method for high-resolution imaging of the supra-aortic vessels because of its easy application and high sensitivity and specificity. Limitations can occur in non-compliant patients due to motion artifacts during the measurement time. 相似文献

Complications of plate fixation in metacarpal fractures 总被引:6,自引:0,他引:6
BACKGROUND: The objective of this study is to assess the complications after open reduction and plate fixation of extra-articular metacarpal fractures. METHODS: We retrospectively reviewed the clinical and radiologic records of 129 consecutive patients with 157 metacarpal fractures treated by open reduction and internal fixation with plates between 1993 and 1999. Intra-articular fractures and fractures of the thumb metacarpal were excluded. Eighty-one patients (64 men and 17 women) with 104 fractures were available for review, at an average follow-up of 13.6 months (range, 6-27 months). RESULTS: Twenty-eight patients (35%) and 33 fractures (32%) had one or more complications, including difficulty with fracture healing (12 patients [15%]), stiffness (eight patients [10%]), plate loosening or breakage (seven patients [8%]), complex regional pain syndrome (two patients), and one patient who developed a deep infection. CONCLUSION: Despite technical advances in implant material, design, and instrumentation, plate fixation of metacarpal fractures remains fraught with complications and unsatisfactory results. 相似文献

A retrospective study was performed to investigate the clinical and radiological results of radiolunate arthrodesis in the rheumatoid wrist. Ninety-one wrists in 78 patients were assessed at a mean follow-up of 60 months. Most patients were pain-free and content with the overall result. In 68 wrists the carpus had been repositioned or maintained in neutral or slightly ulnar alignment and no further translation occurred. Midcarpal dislocation occured in ten and midcarpal rotation in 13 wrists. The midcarpal joint underwent further arthritic destruction in 34 wrists and secondary arthrosis in 32 wrists. In 25 wrists the midcarpal joint space remained unchanged. Radiolunate arthrodesis can successfully be performed in wrists even with advanced destruction. In cases with fixed carpal collapse, anatomical repositioning of the lunate and restoration of carpal height should not be attempted as this causes midcarpal dislocation or rotation or precipitates secondary arthrosis. 相似文献

We report the results of a new bone-tendon ligamentoplasty for the reconstruction of chronic injuries of the ulnar collateral ligament at the metacarpophalangeal joint of the thumb. The mean follow-up period was 36 months. Using the Glickel grading system, seven patients had excellent results and one patient had good results. The mean loss of pinch strength was 10% compared with the contralateral thumb. The mean loss of motion at the MP joint was 8%. This technique successfully restores the desired long lasting stability while maintaining mobility of the thumb's metacarpophalangeal joint. 相似文献

The complex regional pain syndrome type I (CRPS I)-formerly named Sudeck's atrophy or reflex sympathetic dystrophy (RSD)-describes a complex of symptoms with chronic, poorly controllable pain, autonomic, sensomotor and trophic alterations. It is mainly caused by trauma or surgery. We describe the rare case of a spontaneous manifestation of a CRPS I in an adolescent patient with typical clinical and radiological findings and the recurrence of symptoms after a one-year symptom-free interval. Symptoms were resolved by an intense multimodal therapy concept. The likely psychosocial origin in this case is discussed. Clinical appearance, diagnostic means and therapy of the CRPS are described. 相似文献

The indices for ulnar translation described by Chamay et al. (1983, Annales de Chirurgie de la Main, Vol. 2, pp. 5-17), and Bouman et al. (1994, Journal of Hand Surgery Vol. 19B, pp. 325-329), and for carpal height described by Youm et al. (1978, Journal of Bone and Joint Surgery, Vol. 40A, pp. 423-431) and Bouman et al. (1994) were compared in pre- and postoperative wrist X-rays of 91 patients with rheumatoid arthritis undergoing radiolunate arthrodesis. Both indices described by Bouman had a higher applicability and sensitivity than the Chamay and Youm indices and are recommended for use with the rheumatoid wrist. However false-negative values may result when the Bouman index for ulnar translation is used to follow up radiolunate arthrodesis. 相似文献
