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.
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.
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 55.1 ± 29.6, NRS 79.20 ± 15.5) to 6 weeks post-treatment (NRS: 22.4 ± 23.6, p = 0.03; NRS: 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).
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.

外侧腓骨足底筋膜炎（LCPF）会导致第五跖骨基部无创伤性疼痛。本研究评估了一种保守治疗（PRP + 石膏固定）对 LCPF 的疗效。
通过病史、临床诊断和超声成像来确定 LPCF。所有患者均在第五跖骨基部近端注射白细胞减少富血小板血浆（PRP），然后用步行石膏固定 3 周。在治疗后 6 周、12 周和 2 年时，采用 NRS、AOFAS 和足部功能指数（FFI）进行随访问卷调查。
本研究纳入了 10 名患者。超声检查结果显示，在 MT5 插入点处外侧腓骨足底筋膜低回声且增厚，腓骨肌腱正常。治疗前（NRS 55.1±29.6，NRS 79.20±15.5）与治疗后 6 周（NRS：22.4±23.6，p=0.03；NRS：38.6±30.3，p=0.005）相比，疼痛明显减轻。FFI 显示，与治疗前（42.6±16.7）相比，在治疗后 12 周（25.7±25.7）和 2 年（9.1±8.5）时均有改善。
超声是诊断 LCPF 的首选方法。PRP 注射后再用步行石膏固定可在 6 周内有效缓解 LCPF 症状，并持续缓解 2 年。
