RESUMEN
BACKGROUND With the development of arthroscopy and suture anchor, the modified BrostrÓ§m technique has made remarkable progress. However, it is unclear which material is most suitable for treating anterior talofibular ligament injury (ATFL). This study evaluated the short-term efficacy of 2 suture anchors (metal vs biodegradable materials) in arthroscopic ATFL repair. MATERIAL AND METHODS From January 2018 to December 2019, 82 patients with ankle disorders (51 men and 31 women) with ATFL injury received arthroscopic repair with suture anchor through the BrostrÓ§m-Gould procedure. The mean age was 38.70±9.35 years (range, 18-54 years). Each patient was followed up. American Orthopedic Foot and Ankle Society score (AOFAS), Karlsson Ankle Functional Score (KAFS), and the Visual Analogue Scale (VAS) were used to evaluate functional status and pain. RESULTS All patients were followed up for 21.21±2.19 months (range, 18-25 months). No complications were found either group. Preoperative clinical and functional scores in both groups had no significant difference (P>0.05). The functional score increased significantly in both groups (P<0.001). At the last follow-up, the mean AOFAS score was 93.00 (90.00, 96.00) in the Biodegradable group and 93.50 (91.00, 96.00) in the Metallic group (P=0.31). The mean KAFS score was 91.50 (85.00, 95.00) in the Biodegradable group and 93.00 (90.00, 95.50) in the Metallic group (P=0.10); the mean VAS score was 1.50 (1.00, 1.80) in the Biodegradable group and 1.30 (0.98, 1.70) in the Metallic group (P=0.22). CONCLUSIONS Arthroscopic repair of ATFL injury with suture anchors can improve the prognosis of CAI. There were no statistically significant differences in clinical and functional outcomes with metal or biodegradable suture anchors at short-term follow-up.

BACKGROUND: Previous studies have shown a wide range of anatomical classifications of the subtalar joint (STJ) in the population and this is related to the different force line structures of the foot. Different subtalar articular surface morphology may affect the occurrence and development of flat foot deformity, and there are fewer studies in this area. The main objective of our study was to determine the association of different subtalar articular surface with the occurrence and severity of flat foot deformity. METHODS: We analyzed the imaging data of 289 cases of STJ. The articular surface area, Gissane's angle and Bohler's angle of subtalar articular surface of different types were counted. The occurrence and severity of flat foot deformity in different subtalar articular surface were judged by measuring the Meary angle of foot. RESULTS: We classified 289 cases of subtalar articular surface into five types according to the morphology. According to Meary angle, the flat foot deformity of Type I and Type IV are significantly severer than Type II (P < 0.05). Type II (7.65 ± 1.38 cm2) was significantly smaller than Type I (8.40 ± 1.79 cm2) in the total joint facet area(P < 0.05). Type III (9.15 ± 1.92 cm2) was smaller than Type I (8.40 ± 1.79 cm2), II (7.65 ± 1.38 cm2) and IV (7.81 ± 1.74 cm2) (P < 0.05). Type II (28.81 ± 7.44∘) was significantly smaller than Type I (30.80 ± 4.61 degrees), and IV (32.25 ± 5.02 degrees) in the Bohler's angle (P < 0.05). Type II (128.49 ± 6.74 degrees) was smaller than Type I (131.58 ± 7.32 degrees), and IV (131.94 ± 5.80 degrees) in the Gissane's angle (P < 0.05). CONCLUSIONS: After being compared and analyzed the measurement of morphological parameters, joint facet area and fusion of subtalar articular surface were closely related to the severity of flat foot deformity and Type I and IV were more likely to develop severer flat foot deformity. LEVEL OF EVIDENCE: Level III, retrospective comparative study.

INTRODUCTION: The coracoid process is an important anatomical structure of the scapula, which can be used as a landmark in the diagnosis and treatment of scapula related diseases, such as acromioclavicular joint dislocation, anterior shoulder instability, and coracoid fractures. The aim of this study was to classify the coracoid process according to morphology and to measure the morphological parameters of the coracoid process. MATERIALS AND METHODS: A total of 377 dry and intact scapulae were collected and classified in terms of the connection between the shape of coracoid process and common things in life. The anatomical morphology and the position related to acromion and glenoid socket of the coracoid process were measured in each type by three independent researchers with a digital caliper. The measurements were averaged and recorded. RESULTS: Based on obvious morphological features, five specific types of the coracoid process were described: Type I, Vertical 8-shape; Type II, Long stick shape; Type III, Short stick shape; Type IV, Water drop shape, and Type V, Wedge shape. Type I (30%) and Type III (29%) were more prevalent in China. The tip width of the coracoid process of Type IV was the shortest and significantly different compared to the other types (p <.05), contrary to the longest in Type V. The tip thickness of the coracoid process of Type I was the shortest and significantly different from the other types (p <.05). CONCLUSIONS: The coracoid process was classified into five types based on obvious morphological features. Knowing of morphological classification and anatomical parameters of different types of the coracoid process, to some extent, may be helpful to diagnose and treat the shoulder joint disease, such as acromioclavicular joint dislocation, anterior shoulder instability, and coracoid fractures, and to theoretically reduce postoperative complications.

OBJECTIVE: An agreement has not been reached on optimal locations of bone tunnels for coracoclavicular ligament (CCL) reconstruction for acromioclavicular joint dislocation (ACD). This study aims to identify the convergence point (cP) between the coracoid process and clavicle in the Chinese population to assist surgeons in reconstructing the CCL for ACD. METHODS: From 2014 to 2020, 483 CT scans of the shoulders of 270 male and 213 female patients (247 right and 236 left shoulders) were collected and studied retrospectively. By overlapping the images of the transverse plane of the coracoid process and the clavicle, points a and b, and the midpoint ab (cP) were determined. Then, a series of parameters through point cP in the transverse and sagittal planes were measured. In the transverse plane this included the distance from point cP to the tip of the coracoid process (cP-cor),the distance between the medial and lateral margins of the coracoid process through point cP (Med-lat cor), the distance from point cP to the acromioclavicular joint (cP-ac), and the distance between the anteroposterior margin of the clavicle through point cP (Ap-clav). In the sagittal plane, this included the craniocaudal segment of the coracoid process (Cc-cor), and the craniocaudal segment of the clavicle (Cc-clav). The sex and side differences of these measurements were also analyzed by two radiologists. RESULTS: Based on the following measurements, point cP was determined. For male patients, the cP-cor was 28.02 ± 3.43 mm, Med-lat cor was 22.78 ± 2.80 mm, Cc-cor was 15.11 ± 2.13 mm, cP-ac was 29.24 ± 3.84 mm, Ap-clav was 18.27 ± 2.46 mm, and Cc-clav was 10.09 ± 1.56 mm. For female patients, the cP-cor was 25.20 ± 3.26 mm, Med-lat cor was 20.21 ± 2.97 mm, Cc-cor was 13.03 ± 1.77 mm, cP-ac was 26.66 ± 3.45 mm, Ap-clav was 16.10 ± 2.30 mm, and Cc-clav was 8.91 ± 1.40 mm. All the measurements of female patients were lower than those of male patients (p < 0.01). Between sides, only cP-ac of the left shoulders was significantly lower than those of the right shoulders (p < 0.05), with no significant differences in other parameters between sides (p > 0.05). CONCLUSION: The results of this study identified the locations of bone tunnel-cP in the coracoid process and clavicle for the CCL reconstruction in ACD. Moreover, the findings indicated that surgeons should be more cautious in operating on female patients and that the cP-ac of left shoulders should be set lower than that of right shoulders.
