Background

Screws generate and maintain compression against distracting forces when performing osteotomy or fusion surgery. Headless screws have been recently designed with opposing flank angles (OFA) between the proximal and shaft threads and are purported to achieve better compression. The aim of this study was to compare OFA designs against traditional parallel flank angle (PFA) headless screws, and headed screws, to determine differences in compression and pull-out strength (POS).

Methods

This was a biomechanical, in-vitro sawbone study comparing four screw designs: two opposing flank headless designs (Screw AO, Screw BO), one parallel flank headless design (Screw CP) and one headed design (Screw DH). All screws were 4.0 mm diameter x 50 mm length, partially threaded, cannulated screws typically used in foot and ankle surgery (five screws tested for each design). Screw BO had a shorter and narrower proximal threaded portion than Screws AO and CP. A custom apparatus was designed for measuring compression and POS. An osteotomy was created in sawbone blocks of 0.32 g/cm 3 density which simulated cancellous bone. The divided segments were apposed with four strain-gauged load cells in between. Screws were inserted per manufacture recommendations, perpendicular to the osteotomy and maximum compression was measured. To measure POS, block segments were distracted in increasing increments until the construct failed.

Results

There was a significant difference in compression between all screws: Screw AO, 311.0 ± 4.2 N; Screw CP, 201.4 ± 28.6 N; Screw BO, 168.6 ± 15.9 N; Screw DH, 119.8 ± 13.2 N (p < 0.001). There was no significant difference in POS between Screw AO (466.0 ± 29.0 N) and Screw Cp (399.0 ± 46.0 N, p = 0.089), but the other screws had significantly lower POS: Screw BO, 310.0 ± 22.0 N; Screw DH, 183.0 ± 12.9 N (p < 0.001).

Conclusion

One of the OFA designs exhibited the highest compression and POS in this sawbone model. However, the variable results between designs suggests other screw design features may have a greater influence than the opposing of flank angles.
背景:在进行截骨术或融合手术时,螺钉产生并维持对分散力的压迫。最近设计的无头螺钉在近端螺纹和轴螺纹之间具有相对的侧面角(OFA),据称可以实现更好的压缩。本研究的目的是比较OFA设计与传统的平行侧角螺钉(PFA)无头螺钉和有头螺钉,以确定压缩和拉出强度(POS)的差异。方法采用生物力学、体外锯骨研究方法,比较了4种螺钉设计:2种相对的侧腹无头设计(螺钉AO、螺钉BO)、1种平行侧腹无头设计(螺钉CP)和1种头部设计(螺钉DH)。所有螺钉均为4.0 mm直径x 50 mm长度,部分螺纹空心螺钉,通常用于足部和踝关节手术(每种设计测试5颗螺钉)。BO螺钉比AO螺钉和CP螺钉的近端螺纹部分更短、更窄。设计了一种定制的仪器来测量压缩和POS。在0.32 g/ cm3密度的锯骨块中创建截骨,模拟松质骨。分开的节段之间放置四个应变测压元件。按照推荐的制作方法插入螺钉,垂直于截骨,测量最大压缩。为了测量POS,块段以递增的增量分散注意力,直到构造失败。结果各螺钉间的受压程度差异有统计学意义:螺钉AO为311.0 ± 4.2 N;螺钉CP, 201.4 ± 28.6 N;螺钉BO, 168.6 ± 15.9 N;螺钉DH, 119.8 ± 13.2 N (p <; 0.001)。之间没有显著差异在POS螺钉AO(466.0 ±29.0  N)和螺旋Cp( 399.0±46.0  N, p = 0.089),但是其他螺丝有明显降低POS:螺旋波, 310.0±22.0  N;螺钉DH, 183.0 ± 12.9 N (p <; 0.001)。结论在锯骨模型中,其中一种OFA设计表现出最高的压缩和POS。然而,不同设计之间的不同结果表明,其他螺钉设计特征可能比侧面角的相反方向有更大的影响。

There is limited research supporting the existence of a standardized assessment tool in South Africa that aids podiatrists in the early diagnosis of developmental delays, including neurological delays, in paediatric patients. The Gait and Lower Limb Observation Proforma (GALLOP) Assessment Tool is a potential solution for South African podiatrists to enhance their assessments.

Aim

This study aimed to evaluate the "ease of use" and "usefulness" of the GALLOP Assessment Tool for podiatrists when performing paediatric neurological assessments.

Methods

A mixed-methods descriptive study was conducted with all Health Professions Council of South Africa (HPCSA)-registered podiatrists in the Johannesburg Metropolitan Municipality. Participants used the GALLOP Assessment Tool for three months before completing a survey assessing its ease of use and effectiveness.

Results

The findings revealed that all participants found the neurological assessment section of the GALLOP Assessment Tool difficult to use. Major barriers included a lack of knowledge, confidence, and time required for proper implementation.

Conclusion

The study highlights a critical gap in podiatrists' ability to conduct neurological assessments due to inadequate training and a lack of standardized tools. Addressing these issues through improved education, structured neurological training, and the refinement of the GALLOP Assessment Tool could enhance the early detection and management of paediatric neurological conditions.

Clinicians often argue that research fails to capture the individualised nature of their custom foot orthoses prescriptions, resulting in inaccuracies in reported outcomes. Conversely, researchers prioritise standardisation but may inadvertently underestimate the true potential of foot orthoses in achieving positive clinical outcomes. To bridge these gaps, we advocate for various strategies.

The scarf osteotomy is a popular procedure for hallux valgus correction, but variability exists in its execution. This Delphi consensus study aimed to establish a standardised sequence of key procedural steps to guide training, simulation and assessment. A three-round Delphi process was conducted with an expert panel of foot and ankle surgeons. Statements achieving predefined consensus thresholds were included in the final recommendations. The study provides a framework for procedural standardisation, which can be used to inform training curricula, design of simulation training and assessment criteria. The findings also contribute to the literature aimed at improving surgical consistency and reducing complications associated with technical variability.

Introduction

Adult Acquired Flatfoot Deformity (AAFD) is a progressive condition characterized by the collapse of the medial foot arch, often caused by posterior tibial tendon dysfunction or deltoid spring ligament incompetency. Flexible type 2 AAFD results in peritalar subluxation and instability. The deltoid and spring ligament complex plays a critical role in foot stability. Current surgical treatments include ligament reconstructions, tendon transfers, and osteotomies, but comprehensive approaches for advanced cases are limited. This study compares two novel techniques—Quadrangular and Triangular repairs—using fiber tape or wire for reconstruction of the deltoid spring complex, combined with medial displacement calcaneal osteotomy (MCDO) for Stage II AAFD.

Materials and methods

Forty patients (mean age 44.6 years) with Stage II AAFD, unresponsive to conservative treatment, were enrolled between December 2023 and 2024. Both surgical techniques, combined with MCDO (excluding lateral column lengthening), were performed. Clinical and radiological assessments were made preoperatively, at 3 months, and at 12 months. The AOFAS Ankle-Hindfoot scale assessed functional outcomes, while radiological parameters such as Meary's angle, talonavicular coverage, and tibial-calcaneal angle were evaluated.

Results

At 3 and 12 months post-surgery, both techniques showed significant improvements in clinical (AOFAS) and radiological outcomes, including Meary’s angle and hindfoot alignment (p < 0.01). Triangular repair demonstrated slightly better functional outcomes, but both techniques effectively restored foot biomechanics and alignment. Complications included wound dehiscence, metal irritation, and persistent subtalar pain, which resolved with conservative treatment.

Conclusion

Quadrangular and Triangular repair techniques, augmented with fiber tape or wire and combined with MCDO, are effective for Stage II AAFD. Both methods improve clinical and radiological outcomes, with Quadrangular repair showing a slight advantage in functional recovery in severe deformity. These findings suggest that a personalized approach based on talonavicular coverage optimizes AAFD management.
成人获得性扁平足畸形(AAFD)是一种进行性疾病,其特征是内侧足弓塌陷,通常由胫骨后腱功能障碍或三角肌弹簧韧带功能不全引起。柔性型2型AAFD导致肱骨周围半脱位和不稳定。三角肌和弹簧韧带复合物在足部稳定性中起着关键作用。目前的手术治疗包括韧带重建、肌腱转移和截骨术,但对晚期病例的综合治疗方法有限。本研究比较了两种新技术-四边形和三角形修复-使用纤维带或金属丝重建三角肌弹簧复合体,并结合内侧移位跟骨切开术(MCDO)治疗II期AAFD。材料和方法2023年12月至2024年12月,40例对保守治疗无反应的II期AAFD患者(平均年龄44.6岁)入组。两种手术技术,结合MCDO(不包括侧柱延长)进行。术前、3个月和12个月分别进行临床和放射学评估。AOFAS踝-后足量表评估功能结果,同时评估影像学参数,如Meary角、距舟骨覆盖范围和胫骨-跟骨角。结果术后3个月和12个月,两种技术的临床(AOFAS)和影像学结果,包括Meary角和后足对中(p <; 0.01)均有显著改善。三角形修复显示出稍好的功能结果,但两种技术都有效地恢复了足部生物力学和对齐。并发症包括伤口裂开、金属刺激和持续距下疼痛,经保守治疗后消失。结论四边形和三角形修复技术加纤维带或金属丝并联合MCDO治疗II期AAFD是有效的。两种方法都能改善临床和影像学结果,四边形修复在严重畸形的功能恢复方面显示出轻微的优势。这些结果表明,基于距舟骨覆盖的个性化方法可优化AAFD的治疗。

Background

Achilles tendinopathy is a common overuse injury among athletes, classified into mid-portion and insertional types. While existing literature primarily emphasizes mid-portion tendinopathy as the more prevalent form, emerging evidence highlights the significance of insertional tendinopathy. Variations in clinical presentation warrant further investigation, particularly regarding anatomical differences that could inform treatment strategies and rehabilitation protocols.

Purpose

This study aimed to assess the prevalence of Achilles tendon pathologies and explore anatomical differences in the length of the free tendon between insertional and mid-portion tendinopathy.

Study design

This study represents a cross-sectional analysis conducted as part of a larger longitudinal study on the mechanical properties of patients with Achilles tendinopathy.

Methods

A total of 103 patients (38.8 % males, 61.2 % females, age: 53 ± 12.8 years, body Mass Index (BMI): 30 ± 7.4 kg/m2, 60 % sedentary while 40 % active) diagnosed with Achilles tendon pathologies from across the Maltese islands were recruited for ultrasound assessments to measure tendon length and evaluate associated anatomical characteristics. Participants were categorised based on the type of tendinopathy.

Results

A higher prevalence of insertional tendinopathy (67.9 %) was identified compared to mid-portion tendinopathy (20.3 %). Notably, participants with insertional tendinopathy presented with short tendons (3.8 ± 1.4 cm, p = <0.001) compared to those with longer free tendon length in mid-portion tendinopathy (5.9 ± 1.3 cm, p = <0.001). This anatomical distinction, along with the lower attachment of the soleus muscle, may contribute to differing biomechanical properties, influencing the risk of specific tendon pathologies.

Conclusions

This study is the first to report a higher prevalence of insertional tendinopathy and to highlight the link between short free tendon length and insertional tendinopathy. This emphasizes the importance of monitoring short free tendons, as they are likely pivotal in the development of insertional tendinopathy.
背景:跟腱病是运动员中常见的过度使用损伤,分为中部型和插入型。虽然现有文献主要强调中部肌腱病变是更普遍的形式,但新出现的证据强调了插入性肌腱病变的重要性。临床表现的差异需要进一步调查,特别是解剖差异可以为治疗策略和康复方案提供信息。目的本研究旨在评估跟腱病变的患病率,并探讨插入型和中位型跟腱病变游离肌腱长度的解剖学差异。研究设计本研究是一项横断面分析,是对跟腱病患者力学特性进行的大型纵向研究的一部分。MethodsA共有103名患者(38.8 %雄性,61.2 %女性,年龄:53 ± 12.8年,身体质量指数(BMI): 30 ±7.4  kg / m2, 60 %久坐而40 %活跃)诊断为跟腱病态来自马耳他群岛的人被招募为超声评估肌腱长度测量和评估相关的解剖特征。参与者根据肌腱病变的类型进行分类。结果插入肌腱病变的患病率(67.9% %)高于中间部分肌腱病变(20.3% %)。值得注意的是,参与者与插入病变呈现短肌腱( 3.8±1.4  厘米,p = & lt; 0.001)相比自由肌腱长度较长的明显病变( 5.9±1.3  厘米,p = & lt; 0.001)。这种解剖学上的差异,以及比目鱼肌的下附著,可能导致不同的生物力学特性,影响特定肌腱病变的风险。结论:本研究首次报道了插入性肌腱病变的较高患病率,并强调了游离肌腱长度短与插入性肌腱病变之间的联系。这强调了监测短游离肌腱的重要性,因为它们可能是插入性肌腱病发展的关键。

Ankle-foot orthoses (AFOs) are of important in the management of gait deformities in most neurological conditions through stabilising and supporting the ankle and foot. Despite its importance, there is a lack of knowledge about how some design parameters, particularly trimline geometry, affect AFO stiffness. This study employs a parametric finite element (FE) model to quantify the impact of trimline design on rigidity to improve standardisation of AFO prescription manufacture, and quality control. A parametric model was developed to systematically modify trimline placement and analyse its effect on AFO stiffness. A dorsiflexion moment of 30 Nm was employed to simulate loading conditions, with experimentally determined material properties of polypropylene. The parametric model was developed and validated against experimental results. Trimline positions were manipulated systematically by 1 mm in the proximal and 10 mm in the distal direction of ankle to investigate their impact on stiffness. Thickness, loading, and constraints were controlled for in the analysis. The results of this study verify that the model accurately predicts ankle dorsiflexion, and there are small discrepancies between calculation and experiment. Having more than five transverse plates proximal to the footplate and distal to the ankle does not significantly impact stiffness. Furthermore, trimline position has significant effect in AFO rigidity, that even small changes affect stiffness. Change in trimline posterior to the ankle produced a linear decrease in stiffness, while trimline adjustments distal to the ankle had a nonlinear effect. These findings emphasise the importance of precise prescription and quality control of trimlines to optimise the AFO function.
踝足矫形器(AFOs)通过稳定和支持脚踝和足,在大多数神经系统疾病的步态畸形管理中具有重要意义。尽管它很重要,但人们对一些设计参数,特别是边缘几何形状,如何影响AFO刚度缺乏了解。本研究采用参数化有限元(FE)模型,量化三棱线设计对刚性的影响,以提高AFO处方生产的标准化和质量控制。建立了一个参数化模型,系统地修改了切线位置,并分析了其对AFO刚度的影响。采用30 Nm的背弯力矩模拟加载条件,并通过实验确定聚丙烯的材料性能。建立了参数化模型,并与实验结果进行了对比验证。系统地在踝关节近端和远端分别操作1 mm和10 mm的边缘线位置,以研究它们对刚度的影响。在分析中控制了厚度、载荷和约束条件。本研究结果验证了该模型能准确预测踝关节背屈,且计算与实验误差较小。在足底近端和踝关节远端有超过5个横向钢板不会显著影响僵硬度。此外,侧边线位置对AFO刚度有显著影响,即使很小的变化也会影响刚度。踝关节后侧线的改变会产生线性的刚度降低,而踝关节远端侧线的调整则会产生非线性的影响。这些发现强调了精确处方和质量控制的重要性,以优化AFO功能。

Background

Loss of balance and consequent falls are leading causes of mortality and morbidity in the geriatric population. In terms of ease of application, plantar sensory-based exercises seem to be superior to other balance development exercises. Our study's objective is to examine the effects of plantar sensation education-based exercises on balance and falls.

Materials and methods

16 healthy, voluntary nursing home residents with the average age 77.50 ± 5.5. Individuals had plantar sensory exercises 40 min sessions for 3 days/week during eight weeks. The study was planned as a self-controlled prospective study. Functional balance was evaluated using Berg Balance Scale, dynamic balance was evaluated using 30 Second Chair Stand Test, static balance and fall risk were assessed using Biodex Balnce System.

Results

The measurements of static balance and fall tests with the Biodex balance device after 8 weeks of plantar sensation exercises program showed significant improvement compared to the results before the treatment (p < 0.05). The measurements of the Biodex balance device before the treatment were 3.45 ± 2.41, whereas the ones after the treatment showed 2.61 ± 2.18. The result of the fall risk measured by the Biodex balance device was 3.43 ± 3.11 before the treatment, whereas it came out as 2.46 ± 2.02 after the treatment. (p < 0.05)

Conclusion

Static balance and fall risc play a significant role in the well-being of nursing home residents through exercise programs designed for plantar sensation. According to these outcomes, we believe that exercises intended for plantar sensation will be an effective treatment approach in terms of increasing the static balance and decreasing the fall risk with nursing home residents.

Calcaneal fractures comprise 1–2 % of all fractures and typically occur in younger, working age male patients. These injuries result in a significant burden to the patient in terms of residual pain, inability to work or participate in sports, difficulty with shoe wear and secondary reconstructive surgery such as subtalar arthrodesis. They also result in a significant burden to the healthcare system. Calcaneal fractures can be sub-classified into extra-articular and intra-articular, two-thirds of calcaneal fractures involve the articular facets of the subtalar joint. The treatment of displaced intra-articular calcaneal fractures is controversial, with many authors recommending non-operative treatment. The concerns with this approach include painful malunion, articular surface disruption, heel varus and increased calcaneal width, with a significant rate of secondary reconstructive surgery. Traditional operative approaches for calcaneal fractures allowed the surgeon to restore anatomic parameters, but have been associated with high rates of soft tissue complications, up to 40 % in some series. Newer, less invasive techniques for fixation allow the surgeon to obtain a similar anatomic reduction with reduced tissue compromise. We performed a systematic literature search which identifed forty articles on which this review is based. In this review article we discuss the background of displaced, intra-articular calcaneal fractures and compare the current knowledge base of operative vs. non-operative management. We then compare and contrast the three common surgical approaches used for treatment of these injuries: the extensile lateral approach, the sinus tarsi approach and newer percutaneous/minimally invasive techniques. At the current time, the sinus tarsi approach is the mainstay for treating these fractures, with most authors favouring this over the extensile lateral approach. There is momentum for adoption of newer minimally invasive techniques which show promising results, with reduced soft tissue complications and satisfactory functional outcomes.
跟骨骨折占所有骨折的1-2 %,通常发生在年轻,工作年龄的男性患者。这些损伤给患者带来了严重的负担,包括残余疼痛、无法工作或参加运动、穿鞋困难和继发性重建手术,如距下关节融合术。它们也给医疗保健系统带来了沉重的负担。跟骨骨折可分为关节外骨折和关节内骨折,三分之二的跟骨骨折涉及距下关节的关节面。移位的跟骨关节内骨折的治疗是有争议的,许多作者推荐非手术治疗。该入路的问题包括疼痛的骨不愈合、关节面破裂、足跟内翻和跟骨宽度增加,并且二次重建手术的发生率很高。跟骨骨折的传统手术方法允许外科医生恢复解剖参数,但与软组织并发症的高发生率相关,在某些系列中高达40% %。更新的、侵入性更小的固定技术使外科医生能够在减少组织损伤的情况下获得类似的解剖复位。我们进行了系统的文献检索,确定了本综述所依据的40篇文章。在这篇综述文章中,我们讨论了移位,关节内跟骨骨折的背景,并比较了目前手术与非手术治疗的知识基础。然后,我们比较和对比了用于治疗这些损伤的三种常见手术入路:可伸展外侧入路、跗骨窦入路和较新的经皮/微创技术。目前,跗骨窦入路是治疗此类骨折的主要方法,大多数作者倾向于采用这种入路而不是可伸展外侧入路。有动力采用新的微创技术,显示有希望的结果,减少了软组织并发症和令人满意的功能结果。

Introduction

Proximal interphalangeal joint (PIPJ) arthrodesis is indicated for the treatment of lesser toe deformities. K-wires have traditionally been the standard of care for PIPJ arthrodesis, however intramedullary implants may be superior. This systematic review evaluates the union rate and outcomes of implants for PIPJ arthrodesis.

Methods

MEDLINE, CENTRAL, EMBASE and Google Scholar databases were reviewed for studies reporting on outcomes of intramedullary implants for PIPJ arthrodesis in hammer or claw toe. The primary outcome measure was union rate. Secondary outcome measures included pain scores, functional improvement, patient satisfaction, quality of life and complications.

Results

12 studies comparing 12 different implants in 797 patients with 1118 treated toes were reviewed. Fusion rates ranged from 22.2 % to 96 % with the highest fusion rates demonstrated with Ossiofiber (96 %, n = 24), Smart toe (43.6–93.8 %, n = 217) and Nextra (84.44 %, n = 47) respectively. 4 studies compared 3 implants to K-wire (Smart toe, Tenfuse and Nextra) with improved union rates demonstrated compared to K-wire (p < 0.05). Function, pain relief, patient satisfaction and quality of life all improved following PIPJ arthrodesis with implants, however these outcomes were equivocal to K-wire. All studies were rated as high or critical risk of bias.

Conclusion

A definitive judgement on the best implant for PIPJ arthrodesis is currently unobtainable due to the high risk of bias in the reviewed studies. Given the high cost of intramedullary implants and equivocal functional outcomes to K-wire, further comparative study with randomised control trials is advised to establish the standard of care for PIPJ arthrodesis.
导言近端指间关节(PIPJ)关节置换术适用于治疗小趾畸形。传统上,K线是PIPJ关节置换术的标准护理方法,但髓内植入物可能更胜一筹。本系统性综述评估了髓内植入物用于 PIPJ 关节置换术的结合率和疗效。方法 回顾了MEDLINE、CENTRAL、EMBASE 和 Google Scholar 数据库中有关髓内植入物用于锤状趾或爪状趾 PIPJ 关节置换术疗效的研究报告。主要结果指标为关节结合率。结果 回顾了 12 项研究,比较了 12 种不同植入物对 797 名患者 1118 个脚趾的治疗效果。融合率从 22.2% 到 96% 不等,融合率最高的分别是 Ossiofiber(96%,n = 24)、Smart toe(43.6-93.8%,n = 217)和 Nextra(84.44%,n = 47)。4 项研究将 3 种植入物与 K 线(Smart toe、Tenfuse 和 Nextra)进行了比较,结果表明,与 K 线相比,植入物的结合率有所提高(p < 0.05)。使用植入物进行 PIPJ 关节固定术后,患者的功能、疼痛缓解、满意度和生活质量都有所提高,但这些结果与 K 型钢丝的效果不相上下。所有研究均被评为高偏倚风险或严重偏倚风险。结论 由于所审查的研究存在较高的偏倚风险,因此目前还无法对PIPJ关节置换术的最佳植入物做出明确判断。考虑到髓内植入物的高昂成本以及与K线相比模棱两可的功能结果,建议进一步开展随机对照试验比较研究,以确定PIPJ关节置换术的护理标准。
