OBJECTIVE: To investigate the effectiveness of spring ligament repair combined with subtalar arthroereisis (STA) and the Kidner procedure for treating children's flexible flatfoot with painful accessory navicular. METHODS: A retrospective analysis was conducted on clinical data from 45 children (45 feet) aged 7-14 years with flexible flatfoot and painful accessory navicular who met the selection criteria and were treated between February 2018 and May 2022. Among them, 23 cases (23 feet) were treated with spring ligament repair combined with STA and Kidner procedure (observation group), while 22 cases (22 feet) received STA with Kidner procedure alone (control group). Comparison of baseline data between the two groups including gender, age, affected side, preoperative visual analogue scale (VAS) score, American Orthopaedic Foot & Ankle Society (AOFAS) score, talonavicular coverage angle (TCA), talus-first metatarsal angle (T1MT), talus-second metatarsal angle (T2MT), talus first plantar angle (Meary angle), calcaneal inclination angle (Pitch angle) showed no significant differences ( P>0.05). The following parameters were recorded and compared between the two groups: operation time, intraoperative blood loss, incision length, hospital stay, time to full weight-bearing, and complication rates. Foot pain and functional recovery were assessed using the VAS score and AOFAS score preoperatively and at last follow-up. Radiographic measurements including TCA, T1MT, T2MT, Meary angle, and Pitch angle were analyzed by comparing preoperative to last follow-up values. RESULTS: Both groups of patients successfully completed the surgery without any procedure-related complications such as vascular, neural, or tendon injury. The operation time in the observation group was significantly longer than that in the control group ( P<0.05). There was no significant difference between the two groups in terms of intraoperative blood loss, incision length, hospital stay, or time to full weight-bearing ( P>0.05). All patients were followed up 23-47 months (mean, 33.7 months). In the control group, 1 patient experienced discomfort during walking, attributed to screw irritation in the sinus tarsi, which resolved after 2-3 months of rehabilitation. None of the remaining patients developed complications such as sinus tarsi screw loosening, peroneal tendon contracture, or wound infection. At last follow-up, the observation group showed significantly better improvements in radiographic parameters (TCA, T1MT, T2MT, Meary angle, Pitch angle) and greater reductions in VAS and AOFAS scores compared to the control group ( P<0.05). CONCLUSION The combined procedure of spring ligament repair, STA, and Kidner procedure for children's flexible flatfoot with painful accessory navicular demonstrates significant improvements in foot appearance, arch collapse correction, and pain relief. This technique offers technical simplicity, minimal intraoperative complications, and satisfactory clinical outcomes.

OBJECTIVE: To evaluate the mid-term efficacy of talonavicular joint fusion alone combined with navicular stress adjustment in Müller-Weiss disease with significant paradoxical flatfoot deformity. METHODS: Between January 2016 and March 2021, a total of 13 patients diagnosed with Müller-Weiss disease underwent simple talonavicular joint fusion combined with navicular stress adjustmentadjustment.Among them, 5 patients were male and 8 patients were female;age ranged from 42 to 67 years old. The duration of the disease ranged from 8 to 20 years. According to Maceira staging system, 5 patients were in stage III and 8 patients were in stage IV. The American Orthopaedic Foot and Ankle Society (AOFAS) midfoot score, visual analogue scale (VAS), and foot length were evaluated preoperatively and 10 months postoperatively. Additionally, the talonavicular coverage angle, the talus-first metatarsal angle, and the calcaneal inclination angle were assessed preoperatively and 6 months postoperatively. RESULTS: All 13 patients were followed up a period ranging from 24 to 40 months. All patients achieved clinical healing within a period of 3 to 6 months. However, one patient experienced a screw fracture. The VAS decreased from a range of 3 to 7 points preoperatively to a range of 0 to 2 points at the 10 months postoperative. The AOFAS midfoot score improved from a preoperative range of 12 to 66 points to a range of 72 to 100 points at the 10 months postoperative. Based on the AOFAS midfoot score evaluated at 10 months postoperatively, the outcomes were rated as excellent in 3 feet, good in 6 feet, and fair in 4 feet. The talo-navicular coverage angle, the preoperative talus-first metatarsal angle, calcaneal inclination angle were 14.3° to 33.4°, -4.6° to -19.6°, and 3.0°to 16.4° respectively. Six months postoperatively, these angles improved to 2.7°to 9.6°, -8.4°to 1.1°, and 18.8°to 24.9°respectively. Additionally, the foot length increased by 0 to 6 mm at 10 months post-surgery. CONCLUSION Simple talonavicular arthrodesis combined with scaphoid stress adjustment has satisfactory clinical efficacy in Müller-Weiss disease in terms of deformity, foot length, foot function and pain.

OBJECTIVE: To analyze radiological characteristics of Muller-Weiss disease, evaluate the clinical value of the imaging examination in diagnosis of Muller-Weiss disease. METHODS: The imaging data of 26 patients with Muller-Weiss disease were collected from September 2015 to August 2020, including 7 males and 19 females, aged 43 to 68 years old with an average of (52.7±4.6) years old. In the X-ray examination observed the shape and position of the navicular bone. The talar-first metatarsal angle(TFM) was measured on the weight-bearing anteroposterior radiograph. The arch angle and angle between mid-axis of talus and mid-axis of the first metatarsal(Meary angle) were measured on the weight-bearing lateral radiographs. The morphology, density, adjacent joint space and position of the navicular bone were evaluated by computed tomography(CT), and magnetic resonance imaging(MRI) was used to observe the shape, signal, cartilage and surrounding soft tissue changes of the navicular bone. RESULTS: Among 26 patients, 21 cases were unilateral and 5 cases were bilateral;X-ray examination showed that the lateral part of navicular bone of foot was compressed and flattened, showing"comma like"or"drop like", navicular moved to the medial side, partial fragmentation of bone, peripheral articular hyperplasia, uneven density and narrowing of relationship gap. According to Meary angle and deformity degree of the affected foot on the lateral X-ray of the load-bearing foot, Maceira staging was performed. There were 0 cases in stageⅠ, 2 cases in stage Ⅱ, 11 cases in stage Ⅲ, 9 cases in stage Ⅳand 4 cases in stage Ⅴ. CT examination showed bone fragmentation, medial displacement of navicular bone and formation of the talocalcaneal joint. MRI examination showed the irregular shape and uneven signal of navicular bone, narrowing of joint space, talocalcaneal joint surface hyperplasia and cartilage destruction, tarsal joint effusion and swelling of surrounding soft tissue. CONCLUSION Muller-Weiss disease has specific imaging manifestation, and an accurate diagnosis can be made based on the patient's age, gender, and clinincal history. Preoperative imaging examination can stage the disease, help clinicians to formulate better surgical plans, and postoperative imaging examination can better evaluate the surgical effect.

BACKGROUND: Mycobacterium bovis Bacille Calmette-Guérin (BCG) osteitis, a rare complication of BCG vaccination, has not been well investigated in Korea. This study aimed to evaluate the clinical characteristics of BCG osteitis during the recent 10 years in Korea. METHODS: Children diagnosed with BCG osteitis at the Seoul National University Children's Hospital from January 2007 to March 2018 were included. M. bovis BCG was confirmed by multiplex polymerase chain reaction (PCR) in the affected bone. BCG immunization status and clinical information were reviewed retrospectively. RESULTS: Twenty-one patients were diagnosed with BCG osteitis and their median symptom onset from BCG vaccination was 13.8 months (range, 6.0–32.5). Sixteen children (76.2%) received Tokyo-172 vaccine by percutaneous multiple puncture method, while four (19.0%) and one (4.8%) received intradermal Tokyo-172 and Danish strain, respectively. Common presenting symptoms were swelling (76.2%), limited movement of the affected site (63.2%), and pain (61.9%) while fever was only accompanied in 19.0%. Femur (33.3%) and the tarsal bones (23.8%) were the most frequently involved sites; and demarcated osteolytic lesions (63.1%) and cortical breakages (42.1%) were observed on plain radiographs. Surgical drainage was performed in 90.5%, and 33.3% of them required repeated surgical interventions due to persistent symptoms. Antituberculosis medications were administered for a median duration of 12 months (range, 12–31). Most patients recovered without evident sequelae. CONCLUSION: Highly suspecting BCG osteitis based on clinical manifestations is important for prompt management. A comprehensive national surveillance system is needed to understand the exact incidence of serious adverse reactions following BCG vaccination and establish safe vaccination policy in Korea.

During routine dissection, additional muscular head of extensor digitorum brevis muscle attaching to the third toe and accessory muscle perforated by the branch of the deep peroneal nerve were observed in the right foot of a 71-year-old male cadaver. The additional muscular head originated from the dorsal surface of cuboid bone, and ran parallel with the third tendon of the extensor digitorum brevis muscle. It was conjoined with the third tendon of extensor digitorum brevis at the middle of its course. The accessory muscle was a small muscle which was covered with the muscle belly of the extensor hallucis brevis muscle. It originated from the dorsal surface of the calcaneus, and inserted to the lateral one-third of transverse retinacular band. These two variants were innervated by the branches of deep peroneal nerve. The branches of deep peroneal nerve were compressed under the tendon of extensor hallucis brevis and around the site where the nerve branch perforated the small muscle. The clinical significances of these variations and tendon of extensor hallucis brevis muscle were discussed.

A 33 years old female patient presented with posttraumatic pain in the right foot for which radiographs of the right foot was advised. No fracture was detected on radiographs and patient was managed conservatively on medications and posterior splint immobilization. We found coincidentally a short fourth metatarsal and an accessory navicular bone in the right foot radiographs. After 3 weeks of immobilization, she underwent mobilization of the right foot, weight bearing and intensive physio- therapy for 6 weeks. After two months of injury she was still complaining of pain on the plantar aspect of right foot which was diagnosed as metatarsalgia and operated on by excision of the neuroma present in the 3rd web space of the right foot. After surgery she was completely relieved of pain and could do activities well related to the right foot.
