ABSTRACT
Objectives: Distal radius malunion can result in pain and functional complaints. One of the functional problems that can affect daily life is impaired forearm rotation. The primary aim of this study was to investigate the effect of corrective osteotomy for distal radius malunion on forearm rotation at 12 months after surgery. We secondarily studied the effect on grip strength, radiological measurements, and patient-reported outcome measurements (PROMs). Patients and methods: This cohort study analysed prospectively collected data of adult patients with symptomatic distal radius malunion. All patients underwent corrective osteotomy for malunion and were followed for 1 year. We measured forearm rotation (pronation and supination) and grip strength and analysed radiographs. PROMs consisted of the Patient-Rated Hand/Wrist Evaluation (PRWHE) questionnaire, Visual Analogue Scale for pain, and satisfaction with hand function. Results: Preoperative total forearm rotation was 112° (SD: 34°), of which supination of 49° (SD: 25°) was more impaired than pronation of 63° (SD: 17°). Twelve months after surgery, an unpaired Student's t-test showed a significant improvement of total forearm rotation to 142° (SD: 17°) (p < 0.05). Pronation improved to 72° (SD: 10°), and supination to 69° (SD: 13°) (p < 0.05). Grip strength, PROMs, as well as inclination and volar tilt on radiographs improved significantly during the first year after surgery (p < 0.05). Conclusion: In patients with reduced forearm rotation due to distal radius malunion, corrective osteotomy is an effective treatment that significantly improves forearm rotation. In addition, this intervention improves grip strength, the PRWHE-score, pain, and satisfaction with hand function.
ABSTRACT
BACKGROUND: A significant proportion of patients still report pain following a surgical release for de Quervain disease (DQ). This study aimed to investigate the effectiveness of a surgical release for DQ and to identify the preoperative factors associated with pain after a surgical release for DQ. METHODS: This prospective cohort study includes 707 patients who underwent a surgical release and completed the Visual Analog Scale Questionnaire (VAS, range 0-100). We used a paired t-test to analyse the effectiveness of the surgical release on pain at three months post-operatively compared to the pre-operatively measured outcome. A hierarchical multivariable linear regression model was created to investigate the contribution of the patient- and disease characteristics to post-operative pain. RESULTS: All VAS domains showed improvement after surgical release. On average, the mean VAS pain decreased by 44 points (95% CI 42; 46). Smoking (B=6.37; p<0.01), younger age (B=-0.35; p<0.01), longer duration of complaints (B=0.13; p<0.01), concomitant surgery (B=14.40; p<0.01) and higher VAS pain scores at intake (B=0.15; p<0.01) were associated with worse VAS pain scores post-operatively. Together, the variables explained 11% of the variance in mean VAS pain score at three months of follow-up. CONCLUSION: This study confirms that surgical treatment for patients with DQ significantly reduces patient-reported pain. Smoking, younger age, concomitant surgery, duration of complaints, and higher VAS pain scores at intake are associated with worse patient-reported pain three months after surgical release. However, the small effects suggest that these factors should not be considered the only important factors. LEVEL OF EVIDENCE: Therapeutic, II.
ABSTRACT
OBJECTIVES: To investigate the differences of open reduction and internal fixation (ORIF) of complex AO Type C distal radius fractures between two different models of a single implant type. METHODS: A total of 136 patients who received either a 2.4 mm (n = 61) or 3.5 mm (n = 75) distal radius locking compression plate (LCP DR) using a volar approach were followed over two years. The main outcome measurements included motion, grip strength, pain, and the scores of Gartland and Werley, the Short-Form 36 (SF-36) and the Disabilities of the Arm, Shoulder, and Hand (DASH). Differences between the treatment groups were evaluated using regression analysis and the likelihood ratio test with significance based on the Bonferroni corrected p-value of < 0.003. RESULTS: The groups were similar with respect to baseline and injury characteristics as well as general surgical details. The risk of experiencing a complication after ORIF with a LCP DR 2.4 mm was 18% (n = 11) compared with 11% (n = 8) after receiving a LCP DR 3.5 mm (p = 0.45). Wrist function was also similar between the cohorts based on the mean ranges of movement (all p > 0.052) and grip strength measurements relative to the contralateral healthy side (p = 0.583). In addition, DASH and SF-36 component scores as well as pain were not significantly different between the treatment groups throughout the two-year period (all p ≥ 0.005). No patient from either treatment group had a step-off > 2 mm. CONCLUSIONS: Differences in plate design do not influence the overall final outcome of fracture fixation using LCP.
ABSTRACT
Closed multiple metacarpal fractures are uncommon. They are usually associated with significant soft tissue swelling. Early stable fixation and functional rehabilitation optimises outcome. We present a review of 19 patients with 43 metacarpal fractures treated by early open reduction and internal fixation with 2 mm plates. Eighteen patients recovered a full range of motion, while one patient was lost to follow-up. Implant removal on account of extensor irritation was required in only two metacarpals in two patients. Plating of multiple closed metacarpal fractures is a safe, reliable and consistently reproducible treatment method.
