International Hand Function Study Following Distal Radial Access: The RATATOUILLE Study

BackgroundDistal radial access (DRA) has been proposed to improve procedure ergonomics and favor radial artery patency. Although promising data, nothing is known on evolving hand function after DRA.ObjectivesThis study sought to comprehensively evaluate hand function in patients undergoing DRA.MethodsReal-world patients undergoing DRA undertook a thorough multimodality assessment of hand function implementing multidomain questionnaires (Disabilities of the Arm, Shoulder and Hand and Levine-Katz), and motor (pinch grip test) and sensory (Semmes-Weinstein monofilaments test) examinations of both hands. All assessments were performed at preprocedural baseline and planned at 1-, 6-, and 12-month follow-up (FU). Adverse clinical and procedural events were documented too.ResultsData of 313 patients (220 men, age 66 ± 10 years) from 9 international centers were analyzed. The Disabilities of the Arm, Shoulder and Hand and the Levine-Katz scores slightly improved from baseline to FU (P = 0.008 and P = 0.029, respectively). Pinch strength mildly improved from baseline to FU (P < 0.001 for both the left and right hands). Similarly, touch pressure threshold appeared to faintly improve in both the left and right hands (P < 0.012 for all the sites). For both motor and sensory function tests, comparable findings were found for the DRA hand and the contralateral one, with no significant differences between them. Repeated assessment of all tests over all FU time points similarly showed lack of worsening hand function. Access-related adverse events included 19 harmless bleedings and 3 forearm radial artery and 3 distal radial artery occlusions. None affected hand function at FU.ConclusionsIn a systematic multidimensional assessment, DRA was not associated with hand function impairment. Moreover, DRA emerges as a safe alternative vascular access.     

Evaluation of the short-term results of closed reduction and percutaneous K-wires fixation of displaced intra-articular calcaneal fractures (DIACF)

PurposeOptimum management of displaced intra-articular calcaneal fractures (DIACF) still controversial. Open surgery carries the risk of wound complications, while non-operative management has a high incidence of arthrosis. To avoid these complications, minimally invasive and percutaneous fixation was introduced. The purpose of this study was to prospectively evaluate the short term clinical and radiological outcomes after closed reduction and percutaneous fixation of DIACF using K-wires.Patients and methodsOutcomes of twenty patients were evaluated at the final follow up. A functional assessment using the AOFAS scoring system. Radiological parameters recorded included three angles (Böhler’s, Gissane and posterior facet inclination angles) and three distances (calcaneal length, height and width). Any complications were reported at any follow-up.ResultsThe mean patient’s age was 33 ± 15.2 years, 8 (40%) patients with type II fractures, 10 (50%) patients with type III fractures, and 2 (10%) with type IV fracture according to Sanders classification. After a mean follow-up of 9 months, the mean AOFAS score was 84, excellent in 9 patients (45%), good in 9 (45%), and fair in 2 (10%). At the final follow-up the Böhler’s angle, Gissane angle and PFIA was 25.1° ± (5.2), 119.9° ± (9.4) and 51.7° ± (5.9) respectively and the calcaneal height, length and width was 41.8 mm ± (2.1), 75.1 mm ± (3.01) and 40.9 mm ± (2.6) respectively. We had no cases of deep infection, 20% had significant subtalar arthritis.ConclusionThe closed reduction and percutaneous fixation technique for DIACF management offered acceptable clinical and radiographic outcomes, with fewer complications when compared to other management options.

Acute total hip arthroplasty for older patients with acetabular fractures: A meta-analysis

ObjectiveMultiple treatment options for acetabular fractures in geriatric patients exist. However, no large-scale studies have reported the outcomes of acute total hip arthroplasty (THA) in this patient population. We systematically evaluated all available evidence to characterize clinical outcomes, complications, and revisions of acute THA for acetabular fractures in geriatric patients.MethodsMeta-analysis of 21 studies of 430 acetabular fractures with mean follow-up of 44 months (range, 17−97 months). Two independent researchers searched and evaluated the databases of Ovid, Embase, and United States National Library of Medicine using a Boolean search string up to December 2019. Population demographics and complications, including presence of heterotopic ossification (HO), dislocation, infection, revision rate, neurological deficits, and venous thromboembolic event (VTE), were recorded and analyzed.ResultsWeighted mean Harris Hip Score was 83.3 points, and 20% of the patients had reported complications. The most common complication was HO, with a rate of 19.5%. Brooker grade III and IV HO rates were lower at 6.8%. Hip dislocation occurred at a rate of 6.1%, 4.1% of patients developed VTE, deep infection occurred in 3.8%, and neurological complications occurred in 1.9%. Although the revision rate was described in most studies, we were unable to perform a survival analysis because the time to each revision was described in only a few studies. The revision rate was 4.3%.ConclusionsAcute THA is a viable option for treatment of acetabular fracture and can result in acceptable clinical outcomes and survivorship rates in older patients but with an associated complication rate of approximately 20%. Considering the limited treatment options, THA might be a viable alternative for appropriately selected patients.     

浮肩损伤的临床特征和治疗

目的 总结浮肩损伤（floating shoulder injury，FSI）的临床特征和治疗效果。方法1993年1月-2004年9月收治浮肩损伤患者8例，除2例行锁骨固定带固定外，其余6例均行手术治疗，其中单纯行锁骨切开复位重建钢板内固定1例，同时行肩胛骨内固定5例。受伤至手术时间为2h～7d，平均3．5d，术后6个月对患肩功能进行Constant评分判定疗效，并对浮肩损伤的临床特征和治疗进行总结。结果6例患者经过6个月～3年（平均11个月）的随访，锁骨和肩胛骨骨折均愈合，肩关节活动范围无明显受限，但有2例患者在举重物时肩关节有轻度的疼痛，1例患侧上肢肌力较对侧稍减弱。术后6个月患肩功能Constant评分平均为93分。结论浮肩损伤多为高能量暴力所致的不稳定性肩胛带损伤，在治疗方案上尚存争议。但对移位明显的浮肩损伤以及有伴发伤的浮肩损伤进行手术治疗是必要的。
