Background: Mixed results for functional outcomes and long-term fixation have been reported for first metatarsophalangeal arthroplasty. This prospective study was designed to evaluate the migration of the BioPro metatarsophalangeal-1 (MTP-1) joint hemiprosthesis with Roentgen stereophotogrammetric analysis (RSA). Migration patterns of the prosthesis, prosthesis-induced erosion of the metatarsal bone, and clinical outcomes were evaluated sequentially to 5 years postoperation (PO). Methods: Eleven female patients received the BioPro-1 hemiprosthesis. Prosthesis translation and metatarsal erosion were measured with RSA at immediately PO, 6 weeks, and 3, 6, 12, 36, and 60 months postoperatively. Clinical assessment was done by patient questionnaires. Results: RSA data of 9 patients were available for analysis. Median (range) number of markers used in RSA analysis, condition number, and mean error of markers around the prosthesis were 4 (3-7), 320 (208-862), and 0.13 (0.02-0.28), respectively. Progressive subsidence was seen up to 3 years PO (mean 2.1 mm, SE 0.32). Progressive metatarsal erosion was found from 1 year PO (mean 0.49 mm, SE 0.15). Pain, function, and quality scores improved after surgery and did not deteriorate at later follow-up moments. Conclusion: Model-based RSA of the BioPro-1 prosthesis shows nonstabilizing medial and distal translation and metatarsal erosion. Despite the measured migration and erosion, clinical outcomes improved and remained similar up to 5 years postoperation.

Abstract Background Metatarsal fractures are common skeletal injuries of the lower extremity in adults. The majority involves the proximal fifth metatarsal bone. In the current literature, there still exists controversy regarding treatment recommendations for the different fracture entities. Methods All patients suffering from single fractures to the proximal fifth metatarsal bone between 2003 and 2015 were enrolled in this retrospective analysis. Only patients with a minimum follow-up of 12 months were included. The fractures were classified according to Lawrence and Botte (L&B). Data were collected via patient registry, radiographs and a standardized questionnaire (Foot and Ankle Outcome Score = FOAS). For outcome analysis, the nonparametric Mann–Whitney U test was performed and Spearman’s rank correlation coefficient calculated. Results In total, the functional outcomes of 103 patients suffering from fractures to the proximal fifth metatarsal bone were analyzed. L&B type I fractures (n = 13) had a FAOS score of 91 ± 23, L&B type II (n = 67) presented a score of 91 ± 15 and L&B type III (n = 23) a score of 93 ± 11. Surgically treated patients with an L&B type II fracture had no statistically significant better functional outcome in comparison to conservative management (p = 0.89). Operatively treated L&B type III fractures tended to have a better functional score (p = 0.16). The follow-up time was 58 (min: 15; max: 164) months. Conclusions Overall, the functional outcome following fractures to the proximal fifth metatarsal bone is satisfactory. Conservatively treated L&B type II fractures showed an equivalent functional outcome compared to surgical management. Patients with an L&B type III fracture mainly were treated surgically, but difference in FAOS score did not reach level of significance.

Abstract Background This study aimed to measure the length of metacarpal and metatarsal bones in five Iranian sheep breeds and to correlate the length of the bones with ungula measurements. Thoracic and pelvic limbs of 2-year-old, previously untrimmed, pastured Afshari, Moghani, Kurdi, Makoui, and Lori–Bakhtiari ewes, (n = 20 ewes per breed) were collected after slaughter. The following lengths were recorded in the metacarpal and metatarsal bones: from the margo proximalis lateralis to the lateral (L1) and medial (D1) cartilago physialis; from the margo proximalis lateralis to the margo abaxialis of the lateral (L2) and medial (D2) caput; from the cartilago physialis lateralis to the margo abaxialis of the lateral caput (X1); from the cartilago physialis medialis to the margo distalis of the caput ridge (X2) and from the margo axialis of cartilago physialis to the margo axialis of the lateral caput (X3). Additionally, measurements of the ungula including pars dorsalis length, pars mobilis lateralis and medialis height, pars dorsalis height to the ground and to the solea cornea, thickness of the solea in the pars dorsalis, pars mobilis lateralis and medialis, solea cornea length and angulus dorsalis were recorded in the medial and lateral digits of the thoracic and pelvic limbs. Data on length of the metatarsal and metacarpal bones were analysed using mixed model equations while Pearson correlations were calculated between metacarpal and metatarsal bones and ungula measurements. Results Lori- Bakhtiari and Moghani ewes had greater L1, L2, and D1 and D2 while X1, X2 and X3 was greater in Kurdi ewes (P < 0.05). Measurements such as L1, L2, D1 and D2 were greater in the metatarsal than in metacarpal bones (P < 0.05) and the opposite was observed for X1, X2 and X3 (P < 0.05). No asymmetry was observed between the lateral and medial measurements (P > 0.05). Low to moderate correlations were observed between bone and ungula measurements (P < 0.05). Conclusion Under the conditions of this study, differences in metacarpal and metatarsal bone measurements were observed between breeds but no asymmetry was observed between lateral and medial bones. Results indicate an association between metacarpal and metatarsal bones ungula measurements. This could provide baseline information for the development and/or improvement of current ungula health protocols in the studied sheep breeds.

Background. Patients’ dissatisfaction with the results of surgical correction of lesser toes deformities, the shortcomings of methods aimed at eliminating the lateral deviation of the toe in the metatarsophalangeal joint necessitated the development of a new surgical method.The aim. To evaluate short-term results of the new surgical method for the treatment of patients with lesser toes deformity, accompanied with deviation of the toe.Materials and methods. A method of surgical treatment of deviated deformity of the small toes is proposed. The method includes precise marking of the metatarsal osteotomy line according to the previously calculated parameters of optimal shortening and displacement of the metatarsal bone, performing oblique diaphyseal osteotomy of the metatarsal bone, displacing its distal part along the osteotomy plane. According to the proposed method, nine patients were operated on who had a syndrome of nonrigid hammer-like deformity of the second toe with lateral deviation of the toe in the metatarsophalangeal joint. In all patients, the deformity of the second toe was associated with hallux valgus.Results. As a result of the application of the proposed method, it was possible to achieve deformity correction, eliminate the lateral deviation of the second toe in the metatarsophalangeal joint, restore congruence in the joint, achieve consolidation of bone fragments without loss of correction, and improve the appearance and function of the foot. Three months after the operation, a statistically significant improvement was determined, according to the AOFAS LMIS scale, having reached 94.5 ± 4.64 points, which made it possible to speak about the achievement of a good functional result of treatment. Patients noted the opportunity to wear standard footwear, to carry out their labor activity, to engage in physical culture, were satisfied with the result.Conclusion. The use of the proposed new surgical method for deflected deformity of the lesser toes makes it possible to correct the deformity, eliminate lateral deviation of the toe, relieve pain syndrome, achieve a good cosmetic and functional result, restoring the patients’ ability to wear standard shoes.

BACKGROUND: Arthroereisis of the subtalar joint is a common surgical option for children with flat feet. Along with all the advantages of arthroereisis of the subtalar joint, the indications for surgery, the optimal age for surgical treatment, as well as secondary deformities of the forefoot that occur after treatment are debatable. AIM: The aim of this study was to analyze the frequency and degree of I metatarsal elevation after arthroereisis of the subtalar joint in children. MATERIALS AND METHODS: The study group included 106 patients / 202 feet who were treated at the H. Turner Pediatric Orthopedic Institute for the period from 2015 to 2019. The average age was 11 years (8; 13). Arthroereisis of the subtalar joint was performed in two variants: arthroereisis with a locking screw in the calcaneus 44 patients / 83 feet and arthroereisis with a locking screw in the talus 62 patients / 119 feet. An analysis was made of the incidence of I metatarsal elevation after arthroereisis of the subtalar joint. The relationship between the degree of elevation of the first metatarsal bone and the main clinical and radiological characteristics of the feet at different times after surgical treatment was analyzed. RESULTS: The frequency of elevation of the I metatarsal bone with the use of a calcaneal locking screw was 20.7%, and with the use of a talar locking screw, the frequency is 51.6%. Clinical manifestations of elevation of the I metatarsal bone took place when the amount of elevation was more than 65% of the size of the head of the I metatarsal bone. At a period of 23 years after the operation, elevation of the I metatarsal bone were noted in 15.9%. A statistically significant correlation (Spearman coefficient) was noted between the degree of elevation of the I metatarsal bone and the following parameters: anteroposterior Meary angle (0.360), lateral Kite angle (0.367), lateral Meary angle (0.378), foot arch angle (0.344), tibio-talar angle (0.351), Friedlands index (0.402). CONCLUSIONS: Incidence of the first metatarsal bone elevation reaches 51% of the in patients in the immediate follow-up period after performing arthroereisis of the subtalar joint. Elevation of the first metatarsal bone developed dorsal bunion with an elevation value of more than 65%. The degree of elevation of the first metatarsal bone has a positive correlation with the degree of planovalgus deformity correction. Elevation of the first metatarsal bone tends to decrease up to 15% in the long-term follow-up after surgical treatment.

Background: This study aimed to analyze the correlation between bone mineral density (BMD) and the type of 5th metatarsal fracture, as well as to demonstrate whether there is a difference in radiological findings (heel alignment angle [HAA], heel moment arm [HMA], and metatarsus angle) between fracture types.Methods: A total of 87 patients were enrolled in the study and allocated into 3 groups: the Zone 1 group (N=36), the Zone 2 group (N=33), and the Zone 3 group (N=18). The participants’ demographic data, T-scores, existing fracture or osteoporosis medications, and radiologic parameters including HAA, HMA, and metatarsus adductus angle were analyzed and compared.Results: There was a significant difference between the mean age of the participants, with the highest age in the Zone 1 group and the lowest in the Zone 3 group. Regarding the history of concurrent fracture or osteoporosis medications, there was no significant difference between the 3 groups. Similarly, no significant difference was observed between the 3 groups about the BMD values. In contrast, the HAA was statistically significant in all groups with a positive correlation of -8.9 in the Zone 1 group, a negative correlation of 3.55 in the Zone 2 group, and an inverse relationship of 6.1 in the Zone 3 group. The metatarsus adductus angle was significantly higher in the Zone 3 group than the Zone 1 and Zone 2 groups.Conclusions: The location of a 5th metatarsal bone fracture is not significantly associated with BMD. However, mechanical influences, such as hindfoot varus or forefoot adductus, have a significant correlation with fracture types.
