We report a case of a 14-year-old male with first metatarsocuneiform coalition. With a 1-month history of left foot pain the patient presented to some hospital 8 months ago, where conservative management, including rest, physiotherapy, and medication, was administered. However, symptoms gradually worsened. On admission to our hospital, radiograph revealed a bony bridge at the left first metatarsocuneiform joint, which had enlarged compared with the radiograph 8 months earlier. The patient was diagnosed as first metatarsocuneiform coalition in the left foot and underwent resection of the bony bridge, followed by plaster immobilization for 3 weeks. At 3 months postoperatively, he had resumed normal activity without pain or discomfort. First metatarsocuneiform coalition is a rare type of tarsal coalition. Currently, there are no standardized surgical indications or established treatment protocols. Given the uncertainty of surgical outcomes, conservative treatment should be the primary choice. Surgical intervention may be considered when conservative measures fail or symptoms continue to worsen.

Objective:To investigate the clinical efficacy of a self-designed assistant device for distal ulnar osteotomy and reduction in the surgical treatment of ulnar impaction syndrome.Methods:A retrospective analysis was performed to study the clinical data from the 27 patients with ulnar impaction syndrome who had been treated by distal ulnar shortening and fixation with 2 screws between January 2022 and August 2024 at Department of Hand and Foot Surgery,Affiliated Hospital of Jining Medical University. The cohort included 6 males and 21 females, with 13 left and 14 right sides affected and a mean age of (40.3±10.8) years (range: from 17 to 59 years). Based on their different assistant methods in osteotomy, the patients were divided into group A (15 cases) subjected to conventional freehand osteotomy and group B (12 cases) subjected to distal ulnar osteotomy and reduction assisted by our self-designed assistant device. Comparisons were made between the 2 groups regarding operative time, bone healing time, Mayo wrist function score at postoperative 16 weeks, number of the patients returning to their original occupations and complications.Results:There were no significant dif- ferences in the baseline characteristics between the 2 groups ( P>0.05). All patients were followed up postoperatively for (27.1±11.1) weeks (range: from 16 to 50 weeks). In group B, the operative time [50.0 (50.0, 62.5) min] and bone healing time [6.5 (6.0, 7.0) weeks] were significantly shorter than those in group A [80.0 (67.5, 92.5) min and 7.5 (6.8, 9.0) weeks] ( P<0.05). At postoperative 16 weeks, the Mayo wrist function score was 90.0 (85.0, 96.8) points for group A and 92.5 (85.0, 98.8) points for group B, showing no significant difference ( P>0.05). Five patients in group A and 4 ones in group B returned to their original work status, showing no significant difference either ( P>0.05). One case of non-union occurred in group A while no complication occurred in group B, demonstrating no significant difference either ( P>0.05). Conclusion:In the surgical treatment of ulnar impaction syndrome, compared with conventional freehand osteotomy, application of our self-designed assistant device for distal ulnar osteotomy and reduction is simple, less invasive, and comparable in functional recovery of the wrist, but superior in operative time and bone healing time.

OBJECTIVE: To summarize the effectiveness of orthopedic surgery for patients with moderate and severe hallux valgus and analyze its related influencing factors. METHODS: A clinical data of 247 patients (287 feet) with moderate and severe hallux valgus, who were admitted between January 2013 and October 2024 and met the selection criteria, was retrospectively analyzed. There were 39 males and 208 females, with a median age of 57 years (range, 19-89 years). There were 207 cases of single-foot involvement and 40 cases of double-foot involvement; 159 feet were moderate hallux valgus and 128 feet were severe hallux valgus. The disease duration ranged from 3 months to 25 years, with a median of 5 years and 8 months. The hallux valgus angle (HVA), the intermetatarsal angle (IMA), proximal articular set angle (PASA), and the American Orthopaedic Foot and Ankle Society (AOFAS) scores were measured before operation and at 6 months after operation, and the differences (change values) between pre- and post-operation were calculated. All patients were grouped according to the degree of preoperative hallux valgus deformity and age, and the patients with severe hallux valgus according to different surgical procedures, and the change values of HVA, IMA, and AOFAS scores were compared between groups. All patients were grouped according to postoperative HVA, then the postoperative AOFAS scores were compared between groups. RESULTS: All patients successfully completed the operations and were followed up 6 months to 11 years and 3 months, with an average of 4 years and 6 months. The HVA, IMA, PASA, and AOFAS scores at 6 months after operation showed significant improvement compared to preoperative levels, and the differences were significant ( P<0.05). The patients with severe hallux valgus had the higher change values of HVA, IMA, and AOFAS scores than the patients with moderate hallux valgus ( P<0.05). The elderly patients had the highest change values of HVA and AOFAS scores than the young and middle-aged patients ( P<0.05). The patients with postoperative HVA ranging from 0° to 5° had the highest AOFAS scores than the other patients at 6 months after operation ( P<0.05). Among different surgical procedures for severe hallux valgus, the metatarsophalangeal joint fusion had the highest change value of HVA, the Scarf osteotomy had the highest performance in correcting the IMA, and the first metatarsal base osteotomy had the highest improvement in the postoperative AOFAS score, and the differences were significant ( P<0.05). CONCLUSION Elderly patients show the better improvement in HVA and foot function after operation. The first metatarsal base osteotomy show the better improvement in foot function than other surgical procedures. A certain HVA is allowed to remain after hallux valgus correction, and the postoperative AOFAS score is higher when the corrected HVA is in the range of 0°-5°.
