Abstract

Background

Lateral cord plantar fasciitis (LCPF) causes atraumatic pain at the fifth metatarsal base. This study assesses the outcomes of a conservative treatment (PRP + casting) on LCPF.

Methods

Medical history, clinical diagnosis, and ultrasound imaging were used to determine LPCF. All patients received a leucocyte-poor PRP injection at the proximal part of the fifth metatarsal base, followed by three weeks in a walking cast. Follow-up questionnaires, encompassing NRS, AOFAS, and Foot Functioning Index (FFI), were administered at 6 weeks, 12 weeks, and 2 years post-treatment.

Results

Ten patients were enrolled in the study. Ultrasound findings revealed hyposonant and thickened lateral fascia plantaris at the MT 5 insertion point with normal peronei tendons. There was a notable reduction in pain from pre-treatment (NRS_rest 55.1 ± 29.6, NRS_activity 79.20 ± 15.5) to 6 weeks post-treatment (NRS_rest: 22.4 ± 23.6, p = 0.03; NRS_activity: 38.6 ± 30.3, p = 0.005). FFI indicated an improvement between 12 weeks (25.7 ± 25.7) and 2 years (9.1 ± 8.5) compared to pre-treatment (42.6 ± 16.7).

Conclusion

Ultrasound stands out as the preferred diagnostic method for identifying LCPF. A PRP injection followed by a walking cast proves effective in relieving LCPF symptoms within six weeks with sustained relief up to two years.

足底外侧筋膜病：第五跖骨基底部创伤性疼痛的一个经常被忽视的原因

背景侧索性足底筋膜炎（LCPF）会引起第五跖骨基底部的创伤性疼痛。本研究评估了保守疗法（PRP + 铸模）对 LCPF 的疗效。方法通过病史、临床诊断和超声成像确定 LCPF。所有患者都在第五跖骨基底部近端注射了贫白细胞的 PRP，然后打上石膏行走三周。在治疗后 6 周、12 周和 2 年分别进行随访问卷调查，包括 NRS、AOFAS 和足部功能指数 (FFI)。超声波检查结果显示，MT 5 插入点的足底外侧筋膜松弛、增厚，腓肠肌肌腱正常。从治疗前（NRSrest 55.1 ± 29.6，NRSactivity 79.20 ± 15.5）到治疗后 6 周（NRSrest：22.4 ± 23.6，p = 0.03；NRSactivity：38.6 ± 30.3，p = 0.005），疼痛明显减轻。与治疗前（42.6 ± 16.7）相比，FFI 在 12 周（25.7 ± 25.7）和 2 年（9.1 ± 8.5）之间均有改善。事实证明，注射 PRP 后使用行走石膏可在六周内有效缓解 LCPF 症状，并可持续缓解长达两年。

期刊介绍： The Foot is an international peer-reviewed journal covering all aspects of scientific approaches and medical and surgical treatment of the foot. The Foot aims to provide a multidisciplinary platform for all specialties involved in treating disorders of the foot. At present it is the only journal which provides this inter-disciplinary opportunity. Primary research papers cover a wide range of disorders of the foot and their treatment, including diabetes, vascular disease, neurological, dermatological and infectious conditions, sports injuries, biomechanics, bioengineering, orthoses and prostheses.
