OBJECTIVE
The treatment of talar neck and/or body fractures is known to be difficult and challenging, with significant impact on the long-term functional outcome for the patient. The optimal management, including the choice of surgical approaches and implants, are still under constant discussion. The purpose of the study was to investigate the clinical effects of lateral mini-plate combined with medial lag screws for the treatment of complicated central talar fractures.
METHODS
The data of eight patients with complex central talus fractures treated between June 2019 and January 2021 were retrospectively analyzed. There were six males and two females, ranging in age from 15 to 66 years, with an average age of 37.4 years. There were three cases on the left and five cases on the right. All fractures were comminuted, including talar neck with talar body fracture in seven cases and talar body comminuted with subluxation of subtalar joint in one case. All patients were treated with the anteromedial combined anterolateral approach, lateral talar mini-plate fixation and medial lag screw fixation. Fracture reduction quality, union time, and complications were recorded, and functional outcomes were evaluated using the American Orthopedic Foot & Ankle Society (AOFAS) scoring system.
RESULTS
The time from injury to surgery was 1-6 days, with an average of 3.38 days. The follow-up period was 34-53 months (mean 44.88 months). All fractures healed with a mean healing time of 16.75 weeks (13-23 weeks). Anatomical reduction was observed in six cases and near in two cases. After operation, there was no loosening or breakage of implant, loss of fracture reduction, and irritation of skin and soft tissue by internal fixation. The average AOFAS score was 87.38 (48-100), with excellent five cases, good two cases and poor one case, and the excellent and good rate was 87.5%. Superficial skin necrosis in one surgical incision healed after dressing exchange. No deep infection occurred. One case (1/8, 12.5%) developed avascular necrosis of the talus without collapse. Posttraumatic arthritis was found in four cases (4/8, 50%).
CONCLUSION
The utilization of lateral mini-plates in combination with medial screws for treating complex central talar fractures results in satisfactory reduction and stable fixation, mitigating complications associated with poor reduction. However, due to the absence of an anatomical mini-plate, pre-contouring is necessary when applying the lateral plate. This demands a surgeon's thorough familiarity with the anatomical morphology of the talus and proficiency in surgical techniques. Posttraumatic arthritis is the most common complication of complex central talar fractures.

Reconstruction options for giant cell tumors (GCTs) of bone are limited and challenging due to the amount of structural compromise and the high recurrence rates. This is especially true for GCTs of the foot and ankle, as the area is vital for weight bearing and function. The typical treatment for GCTs is currently excision, curettage, and cementation, although that is not always effective. A 36-year-old otherwise healthy female presented with an original diagnosis of a large aneurysmal bone cyst (ABC) of the distal tibia that had recurred despite two previous attempts at treatment with resection and cementation. She was treated with surgical resection of the lesion, reconstruction, and ankle and subtalar joint arthrodesis with a tibiotalocalcaneal intramedullary nail in combination with a trabecular metal cone. The final pathology of the intraoperative samples was consistent with GCT. Postoperatively, she recovered well, and her imaging was consistent with a successful fusion. This case report provides evidence that tibiotalocalcaneal fusion with a unique combination of hindfoot nail and trabecular metal cone construct in a single procedure is a successful option for the treatment of large, recurrent GCT lesions in the distal tibia.

BACKGROUND
This study aims to analyze the safety and clinical efficacy of using double posterolateral coaxial portals for endoscopic treatment of posterior ankle impingement syndrome (PAIS), a procedure that has gained popularity in recent times.
METHODS
Six fresh foot samples were randomly selected to measure the distances of two posterolateral portals to the sural nerve in different positions (plantar flexion 10°, dorsiflexion 30°, and plantar flexion 30°) for safety evaluation. A prospective analysis was conducted on the clinical efficacy of the operative approach for endoscopic management of posterior ankle impingement syndrome, including evaluation of effectiveness and complications.
RESULTS
In this study, the mean distances of the first and second portals to the sural nerve were measured in different ankle positions. The distances were found to be 2.26 ± 0.22 cm and 1.59 ± 0.12 cm in the plantar flexion 10° position, 2.21 ± 0.21 cm and 1.55 ± 0.12 cm in the dorsiflexion 30° position, and 2.46 ± 0.29 cm and 1.73 ± 0.19 cm in the plantar flexion 30° position, demonstrating a significant safety margin from the nerve. A total of 38 patients underwent endoscopic treatment for posterior ankle impingement syndrome using double posterolateral coaxial portals between January 2012 and December 2017. This surgical approach provided access to the subtalar joint and posterior ankle region. The patients were followed up for an average of 38.2 months (24-72 months), with a satisfaction rate of 94.7%. There were no reported complications, and significant improvements were observed in both visual analogue scale (VAS) and The American Orthopedic Foot and Ankle Society Score (AOFAS) scores postoperatively. The VAS score decreased from 5.68 to 0.51 (P < 0.001), while the AOFAS score increased from 71.68 to 92.34 (P < 0.001), resulting in an excellent/good rate of 97.3%.
CONCLUSION
The use of double posterolateral coaxial portals in the treatment of posterior ankle impingement syndrome offers several advantages, including improved safety, reduced risk of nerve injury, enhanced visualization of the posterior ankle and subtalar joint, favorable clinical outcomes, and minimal complications.

Although calcaneal fracture is not a rare injury and nonunion is rare, proper management of a calcaneal fracture is mandatory because it can be a prerequisite for long-term functional disabilities of the foot, including posttraumatic osteoarthritis of the hindfoot joint, chronic pain, and persistent swelling syndromes. Restoration of axial alignment and joint congruence with careful caution toward soft tissues is the basic principle of treatment; however, few literature reviews to date have addressed the characteristics of a calcaneal nonunion fracture. We discuss a case of a 30-year-old male, manual worker, and diabetic type 1 with a calcaneal fracture reaching the articular surface of the subtalar joint who underwent a simple fracture to a painful nonunion fracture after conservative treatment for seven months before presenting to our hospital being unable to walk with heel deformity. The Ilizarov frame was used to correct deformities in the hindfoot, enhance healing by compressing the fracture site, and allow early weight bearing with the maintenance of subtalar joint function. Our result demonstrates increased calcaneal healing when the Ilizarov foot frame is used, and when the calcaneal fracture site is compressed, this is a good option for maintaining foot and ankle function, even in diabetic patients.

OBJECTIVE
To probe into the effectiveness of vertical compression of locking plate combined with hollow screws in the treatment of Sanders type Ⅱ and Ⅲ calcaneal fractures.
METHODS
The clinical data of 128 patients with Sanders type Ⅱ and Ⅲ calcaneal fractures who were admitted between March 2019 and April 2022 and met the selection criteria were retrospectively analyzed. Among them, 65 patients were treated with locking plate combined with hollow screw vertical compression (study group), and 63 patients were treated with simple locking plate (control group). There was no significant difference in baseline data between the two groups ( >0.05), such as gender, age, fracture side and Sanders classification, cause of injury, time from injury to operation. The operation time, intraoperative blood loss, hospital stay, and fracture healing time were recorded and compared between the two groups. Before operation and at 12 months after operation, the American Orthopaedic Foot and Ankle Association (AOFAS) score (including total score, pain score, functional score, and alignment score) was used to evaluate the recovery of foot function, and imaging indicators such as calcaneal width, calcaneal height, calcaneal length, Böhler angle, and Gissane angle were measured on X-ray films.
RESULTS
All patients were followed up 12 months after operation. There was no significant difference in operation time, intraoperative blood loss, hospital stay, and fracture healing time between the two groups ( >0.05). Poor wound healing occurred in 1 case in the study group and 2 cases in the control group. At 12 months after operation, there was no significant difference between the two groups in the pre- and post-operative difference of calcaneal length, calcaneal height, Gissane angle, and Böhler angle ( >0.05). However, the pre- and post-operative difference in calcaneal width in the study group was significantly higher than that in the control group ( <0.05). The pre- and post-operative difference of AOFAS total score in the study group was significantly higher than that in the control group ( <0.05), and further analysis showed that the pre- and post-operative difference of pain and function scores in the study group were significantly higher than those in the control group ( <0.05), while there was no significant difference in the pre- and post-operative difference of force score between the two groups ( >0.05).
CONCLUSION
Compared with simple locking plate treatment, the treatment of Sanders type Ⅱ and Ⅲ calcaneal fractures with vertical compression of locking plate combined with hollow screws can more effectively improve the width of the subtalar calcaneal articular surface, avoid peroneal longus and brevis impingement, reduce pain, and increase the range of motion of the subtalar joint, and the effectiveness is better.

Subtalar dislocation is characterized by simultaneous dislocation of the subtalar (talocalcaneal) and talonavicular joints, hence the name talocalcaneonavicular. These lesions can be grouped into four distinct categories: anterior and posterior, which are exceptional, lateral and medial. Medial subtalar dislocations are more frequent, are due to low-energy trauma and generally have good functional results. Anatomical reduction and stabilization of the subtalar joint and optimal management of all associated foot injuries are the key to good results.

Comparative Study
OBJECTIVES
The etiology of flatfoot and cavus foot is multicausal and controversial. So far, no literature reports the relationship between the sagittal morphology of subtalar joint and the alignment of foot. The purpose of this study was to explore whether the subtalar alignment would influence the configuration of foot.
METHODS
From January 2017 to January 2020, we included 109 feet in the flatfoot group, 95 feet in the cavus group, and 104 feet in the control group in this retrospective comparative study. The Gissane angle and calcaneal posterior articular surface inclination angle represented the sagittal morphology of the subtalar joint. Meary's angle, calcaneal pitch angle, and talar pitch angle reflected the alignment of foot. They were measured in the weightbearing foot X-rays. The angles in different groups were compared via Mann-Whitney U test. We calculated the correlation between the sagittal alignment of subtalar joint and the alignment of foot using Spearman's correlation analysis. Interobserver and intraobserver reliability were calculated.
RESULTS
The Gissane angle, calcaneal posterior articular surface inclination angle, Meary's angle, talar pitch angle, and calcaneal pitch angle were significantly different in the three groups. The Gissane angle had an excellent correlation with the Meary's angle (r = 0.850, p < 0.0001), and the talar pitch angle (r = -0.825, p < 0.0001), and a good correlation with the calcaneal pitch angle (r = 0.638, p < 0.0001). The calcaneal posterior articular surface inclination angle had an excellent correlation with the Meary's angle (r = -0.902, p < 0.001), and the talar pitch angle (r = 0.887, p < 0.0001), and a good correlation with the calcaneal pitch angle (r = -0.702, p < 0.0001). The interobserver and intraobserver reliability for all radiographic measurements was good to excellent.
CONCLUSION
A subtalar joint with a larger Gissane angle and a more horizontal calcaneal posterior articular surface angle tended to have a higher foot arch and vice versa. The inspiration from this study was that the deformities of flatfoot and cavus foot may relate to the subtalar deformity.

OBJECTIVE
To analyze the clinical data of patients with end-stage ankle and hindfoot arthropathy who underwent tibiotalocalcaneal (TTC) arthrodesis by the same surgeon, explore the short- and mid-term clinical results, complications and functional improvement, and discuss the clinical prognosis and precautions of TTC arthrodesis.
METHODS
Retrospective analysis was made on the clinical data of 40 patients who underwent TTC arthrodesis by the same surgeon from March 2011 to December 2020. In this study, 23 males and 17 females were included, with an average age of (49.1±16.0) years. All the patients underwent unilateral surgery. The clinical characteristics, imaging manifestations, main diagnosis and specific surgical techniques of the patients were recorded. The clinical outcomes were evaluated by comparison of the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score and visual analogue scale (VAS) between pre-operation and at the last follow-up. The fusion healing time, symptom improvement (significant improvement, certain improvement, no improvement or deterioration) and postoperative complications were also recorded.
RESULTS
The median follow-up time was 38.0 (26.3, 58.8) months. The preoperative VAS score was 6.0 (4.0, 7.0), and the AOFAS score was 33.0 (25.3, 47.3). At the last follow-up, the median VAS score was 0 (0, 3.0), and the AOFAS score was 80.0 (59.0, 84.0). All the significantly improved compared with their preoperative corresponding values ( < 0.05). There was no wound necrosis or infection in the patients. One patient suffered from subtalar joint nonunion, which was syphilitic Charcot arthropathy. The median bony healing time of other patients was 15.0 (12.0, 20.0) weeks. Among the included patients, there were 25 cases with significant improvement in symptom compared with that preoperative, 8 cases with certain improvement, 4 cases with no improvement, and 3 cases with worse symptoms than that before operation.
CONCLUSION
TTC arthrodesis is a reliable method for the treatment of the end-stage ankle and hindfoot arthropathy. The function of most patients was improved postoperatively, with little impact on daily life. The causes of poor prognosis included toe stiffness, stress concentration in adjacent knee joints, nonunion and pain of unknown causes.

BACKGROUND
Table tennis is an asymmetric sport involving the powerful forward swing of the upper limbs depends on the solid support of the lower limbs. The foot drive really affects the weight balance and stroke accuracy even though the distance and momentum of the lower limb displacement are limited within a limited range. Given that previous research on table tennis has typically focused on the footwork and stroke performance of professional players, the study aimed to investigate the daily static and dynamic plantar load distribution as well as the centers of gravity balance and rearfoot posture among Taiwanese college elite table tennis players.
METHODS
This is a cross-sectional study of 70 elite male table tennis players (age: 20.0 ± 0.9 years; height: 173.4 ± 5.1 cm, weight: 67.6 ± 5.3 kg, experience: 10.0 ± 1.6 years) and 77 amateur table tennis players of the same gender (age: 20.1 ± 0.8 years, height: 167.4 ± 4.4 cm, weight: 64.3 ± 4.0 kg, experience: 4.4 ± 1.2 years) from Taiwanese universities. The JC Mat optical plantar pressure analyzer was applied to determine the plantar load distribution along with arch index (AI) and centers of gravity balance. Assessment of rearfoot postural alignment was mainly used to contrast the performance of the centers of gravity balance.
RESULTS
The static arch indices of both feet in the elite group were symmetrical and considered normal arches (AI: 0.22 ± 0.07) during their non-training and non-competition daily lives. Their static plantar loads were symmetrically concentrated on the bipedal lateral metatarsals ( < 0.05) as well as shifted to the medial and lateral heels ( < 0.05) and the lateral metatarsals ( < 0.05) during the walking midstance phase. Additionally, the plantar loads were mainly applied to the bipedal medial ( < 0.01) and lateral heels ( < 0.05) during the transitional changes between both states. Elite athletes had symmetrical and evenly distributed centers of gravity on both feet (left: 50.03 ± 4.47%; right: 49.97 ± 4.47%) when standing statically, along with symmetrical rearfoot angles and neutral position of the subtalar joint (left: 2.73 ± 2.30°; right: 2.70 ± 2.32°) even though they were statistically lower than those of the amateur athletes ( < 0.05).
CONCLUSIONS
The daily static and dynamic foot patterns of Taiwanese college elite table tennis players were characterized by plantar load distribution on the lateral metatarsals and the entire calcaneus along with balanced centers of gravity and normal rearfoot posture. This foot and posture layout outlines the excellent athletic performance of the foot and ankle in professional athletes.

BACKGROUND
The biomechanics of the hindfoot in ankle osteoarthritis (OA) are not yet fully understood. Here, we aimed to identify hindfoot motion in a gait analysis using a multi-segment foot model (MFM) according to ankle OA stage and the presence of subtalar compensation defined by hindfoot alignment.
METHODS
We retrospectively reviewed the medical records, plain radiographs, and gait MFM data of 54 ankles admitted to our hospital for the treatment of advanced ankle OA. Spatiotemporal gait parameters and three-dimensional motions of the hindfoot segment were analyzed according to sex, age, body mass index, Takakura classification, and the presence of subtalar compensation. Twenty ankles were categorized as compensated group, and 34 ankles as decompensated group.
RESULTS
No spatiotemporal gait parameters differed significantly according to the presence of subtalar compensation or ankle OA stage. Only normalized step width differed significantly (P = 0.028). Average hindfoot motion (decompensation vs. compensation) did not differ significantly between the sagittal and transverse planes. Graphing of the coronal movement of the hindfoot revealed collapsed curves in both groups that differed significantly. Compared with Takakura stages 3a, 3b, and 4, cases of more advanced stage 3b had a smaller sagittal range of motion than those of stage 3a (P = 0.028). Coronal movement of the hindfoot in cases of Takakura stage 3a/3b/4 showed a relatively flat pattern.
CONCLUSIONS
The spatiotemporal parameters were not affected by the hindfoot alignment resulting from subtalar compensation. The sagittal range of hindfoot motion decreased in patients with advanced ankle OA. Once disrupted, the coronal movement of the subtalar joint in ankle OA did not change regardless of ankle OA stage or hindfoot compensation state.
