Abstract

Background and purpose:  We primarily aimed to report the results of ulnar shortening osteotomy (USO) in cases of ulna impaction syndrome (UIS), and secondarily to assess the influence of etiology, radiographic parameters, and comorbidities on the outcome.

Methods:  Patients with USO performed for UIS between 2014 and 2022 at our department were included in the study. Demographic, surgical, and postoperative data, including complications and revisions, were recorded retrospectively. An additional study-specific follow-up was performed in all available cases, including subjective outcome measures as Patient Related Wrist Evaluation (PRWE) and Quick Disability of the Arm Shoulder and Hand (Quick-DASH) scores, and standardized 90-90° wrist radiographs.

Results:  47 patients were treated with USO at mean age 45.8 years (standard deviation [SD] 16.7); 28 were female; median follow-up was 37 months (interquartile range [IQR] 22-57). Isolated USO was performed in 27 cases; the rest received a combination of procedures, e.g., wrist arthroscopy. USO-specific devices were used in all cases. Reoperations were performed in 12 cases, with implant removal in 11. Postoperative complications such as chronic regional pain syndrome or pseudoarthrosis were detected in 9 patients. 29 patients were additionally examined at median 36 months (IQR 22-49) follow-up. A median PRWE score of 7 (IQR 0-19) and a median Quick-DASH score of 4.5 (IQR 0-15.9) were reported. The subjective improvement was rated as very high by 24 patients. Radiographs showed a mean ulnar shortening of 2.9 mm (SD 1.1) and bone consolidation was achieved in all osteotomies at last follow-up. Relevant comorbidities weakly correlated with worse outcome scores (ρ = 0.41, 95% confidence interval [CI] -0.05 to 0.74 for PRWE and ρ = 0.40, CI -0.06 to 0.73 for Quick-DASH). No statistically significant difference could be detected in any other variables, including UIS etiology.

Conclusion:  We found that USO had good subjective results measure scores, but with relatively high complication and revision rates, including implant removal.

尺短截骨治疗尺嵌塞综合征伴尺方差阳性:回顾性结果分析。
背景和目的:我们的主要目的是报道尺侧短截骨术(USO)治疗尺侧嵌塞综合征(UIS)的结果,其次评估病因、影像学参数和合并症对结果的影响。方法:选取2014 - 2022年在我科因UIS行USO的患者为研究对象。回顾性记录人口统计学、手术和术后数据,包括并发症和手术修复。对所有可用病例进行额外的研究特异性随访,包括主观结果测量,如患者相关手腕评估(PRWE)和臂肩和手的快速残疾(Quick- dash)评分,以及标准化的90-90°腕关节x线片。结果:47例患者接受USO治疗,平均年龄45.8岁(标准差[SD] 16.7);女性28人;中位随访为37个月(四分位数间距[IQR] 22-57)。孤立USO 27例;其余患者接受联合手术,如腕部关节镜检查。在所有病例中都使用了uso专用装置。再次手术12例,取出种植体11例。9例患者出现术后并发症,如慢性局部疼痛综合征或假关节。在中位随访36个月(IQR 22-49)时对29例患者进行了额外检查。PRWE评分中位数为7 (IQR 0-19), Quick-DASH评分中位数为4.5 (IQR 0-15.9)。24例患者主观改善评价非常高。x线片显示,所有截骨手术在最后随访时均实现了平均尺骨缩短2.9 mm (SD 1.1)和骨巩固。相关合并症与较差的预后评分呈弱相关(PRWE组ρ = 0.41, 95%可信区间[CI] -0.05 ~ 0.74,而rapid - dash组ρ = 0.40, CI -0.06 ~ 0.73)。在任何其他变量,包括美国病因学,均未发现统计学上的显著差异。结论:我们发现USO具有良好的主观结果测量评分,但并发症和翻修率相对较高,包括种植体移除。

期刊介绍: Acta Orthopaedica (previously Acta Orthopaedica Scandinavica) presents original articles of basic research interest, as well as clinical studies in the field of orthopedics and related sub disciplines. Ever since the journal was founded in 1930, by a group of Scandinavian orthopedic surgeons, the journal has been published for an international audience. Acta Orthopaedica is owned by the Nordic Orthopaedic Federation and is the official publication of this federation.
