OBJECTIVE: To explore the effectiveness of the flexor digitorum longus (FDL) transfer combined with single-bundle spring ligament reconstruction and medial displacement calcaneal osteotomy in the treatment of stage ⅠAB progressive collapsing foot deformity (PCFD). METHODS: Between January 2019 and September 2023, 19 patients (19 feet) with stage ⅠAB PCFD were treated with FDL transfer combined with single-bundle spring ligament reconstruction and medial displacement calcaneal osteotomy. There were 11 males and 8 females, aged 18 to 60 years, with an average age of 45.5 years. Nine cases were on the left foot and 10 cases on the right foot. The disease duration was 9-21 months, with an average of 12.3 months. Postoperatively, the effectiveness was evaluated by visual analogue scale (VAS) for pain, American Orthopaedic Foot and Ankle Society (AOFAS) score, and Tegner score. Based on X-ray films, the talonavicular coverage angle (TNCA), talus-first metatarsal angle (T1MT), Meary angle, and pitch angle were measured. The plantar pressure parameters of the foot were measured by the Footscan plantar pressure measurement system, including peak pressure and load of the forefoot, midfoot, and hind foot. The patients' satisfaction with the surgical outcome was evaluated. RESULTS: All 19 surgeries were successfully completed. One patient had poor incision healing after operation, while the incisions of the remaining patients healed by first intention. All patients were followed up 12-28 months (mean, 16.8 months). At last follow-up, the VAS score significantly decreased compared with that before operation, and the AOFAS score and Tegner score significantly increased ( P<0.05). Radiological measurements showed that the TNCA, T1MT, Meary angle, and Pitch angle all significantly improved compared with those before operation ( P<0.05). Plantar pressure tests indicated that the peak pressures of the forefoot and midfoot significantly reduced compared with those before operation ( P<0.05), while the peak pressure of the hind foot showed no significant change ( P>0.05). The forefoot load significantly increased and the midfoot load decreased compared with those before operation ( P<0.05), while the hind foot load showed no significant change ( P>0.05). The total satisfaction rate of patients with the surgical outcome (very satisfied+satisfied) reached 84.2% (16/19). CONCLUSION The FDL transfer combined with single-bundle spring ligament reconstruction and medial displacement calcaneal osteotomy can effectively correct the stage ⅠAB PCFD, improve the abnormal distribution of plantar pressure and load, alleviate foot pain symptoms, and improve foot movement function. The patient's satisfaction is high. However, the long-term effectiveness still needs to be further observed and clarified.

Objective To evaluate the clinical efficacy of tendon-regulating and bone-setting manipulation combined with subtalar joint arthroereisis in the treatment of adolescent flexible flatfoot.Methods A retrospective analysis was conducted on the clinical data of 86 children with flexible flatfoot treated at Dongguan Hospital of Guangzhou University of Chinese Medicine(Dongguan Traditional Chinese Medicine Hospital)between December 2022 and February 2024.Based on pre-treatment physician-patient communication,the children were divided into an trial group(44 cases)and a control group(42 cases).The control group received subtalar joint arthroereisis alone,while the trial group received additional tendon-regulating and bone-setting manipulation just once one day before surgery and once weekly postoperatively for one month,with a follow-up period of no less than 6 months.The Visual Analogue Scale(VAS)pain score,American Orthopaedic Foot & Ankle Society(AOFAS)ankle-hindfoot score,Tegner activity score,radiographic parameters,and static plantar pressure parameters of the two groups were observed before and after surgery.Results(1)Regarding clinical data,all surgeries were successfully completed in both groups.There were no statistically significant differences in perioperative general data,including operative time,hospital stays,and complication rates(P＞0.05).All children were followed up for no less than 6 months.The results showed that at the final follow-up,the VAS pain score,AOFAS ankle-hindfoot score,and Tegner activity score were significantly improved in both groups compared to preoperative values(P＜0.05),and the improvement in the trial group was significantly greater than that in the control group(P＜0.05 or P＜0.01).(2)Regarding radiographic parameters,at the final follow-up,the talonavicular coverage angle(TNCA),talus-first metatarsal angle(T1MT),talus-second metatarsal angle(T2MT)on weight-bearing anteroposterior radiographs,and the Meary angle between the talus and the first metatarsal as well as calcaneal Pitch angle(Pitch angle)on weight-bearing lateral radiographs were significantly improved in both groups compared to preoperative values(P＜0.05).The improvement in Meary angle,T1MT angle,and T2MT angle in the trial group was significantly greater than that in the control group(P＜0.01).However,there were no statistically significant differences in TNCA and Pitch angle between the two groups at the final follow-up(P＞0.05).(3)Regarding plantar pressure testing,at the 1-month postoperative follow-up,the forefoot load increased significantly in both groups compared to preoperative values(P＜0.05),while the midfoot load significantly decreased(P＜0.05).The increase in forefoot load and decrease in midfoot load in the trial group were significantly greater than those in the control group(P＜0.05 or P＜0.01).However,there were no statistically significant differences in hindfoot load between preoperative and postoperative values or between the two groups at the 1-month follow-up(P＞0.05).Conclusion For adolescent flexible flatfoot,tendon-regulating and bone-setting manipulation combined with subtalar joint arthroereisis can effectively restore the arch,improve foot mechanical imbalance,thereby correcting flatfoot deformity and enhancing joint motor function.

Objective To study the anti-inflammatory and analgesic effects of Baihuadan Analgesic Spray, so as to provide theoretical basis for further development of new drugs. Methods Prostaglandin E2 (PGE2) in the inflammatory tissues of mice with xylene-induced auricular inflammation and in the rats with albumen-induced pedal swelling were measured for the observation of anti-inflammation action of Baihuadan Analgesic Spray. The pain threshold in mouse hot-plate test and mouse acetic acid writhing test was determined to observe the analgesic effect of Baihuadan Analgesic Spray. Results Middle dose of Baihuadan Analgesic Spray (1 mg/mL) significantly reduced the auricular swelling rate induced by xylene in mice, improved the pain threshold of mice and prolonged pain latency in hot plate test (P < 0.05 or P < 0.01). High dose of Baihuadan Analgesic Spray (2 mg/mL) reduced the content of PGE2 in pedal inflammatory tissues (P < 0.05), and the effect on reducing the times of mouse writhing was obviously superior to that of the Voltaren Gel group. Conclusion Baihuadan Analgesic Spray has obvious anti-inflammatory and analgesic effects.
