RESUMEN
OBJECTIVE: This study aimed to compare the outcomes of traditional surgery (TS) with those of a 3-dimensional model-assisted surgery (3DS) in hallux valgus (HV) surgery with distal chevron osteotomy. METHODS: This randomized controlled trial study included 30 patients randomly grouped as TS and 3DS. In the 3DS group, the surgery was simulated on the 3D model before surgery, and that simulation was used as a guide during surgery. Various parameters, such as angles of the HV, intermetatarsal (IM), and distal metatarsal articular, were measured pre-surgery and during the final follow-up. The extent of lateralization of the first metatarsal (FM) head and plantar displacement of the FM head were assessed. Metrics like the duration of the osteotomy+lateralization+K wire fixation, tourniquet time, and fluoroscopy usage were recorded. All assessments were conducted independently and blindly. Patients remained unaware of their group allocation and the randomization procedure. RESULTS: Both groups showed no statistical differences in gender, operated side, age, or follow-up duration. For instance, in the 3DS group (n=15, age: 44.6 ± 9.6 years, male/female: 14/1, side right/left: 11/4, follow-up duration: 29.4 ± 8.7 months) and TS group (n=15, age: 44.8 ± 9.6 years, male/female: 13/2, side right/left: 10/5, follow-up duration: 28.8 ± 8.4 months). The 3DS group, however, showed better metrics with osteotomy+lateralization+K wire fixation, tourniquet duration, and number of fluoroscopies at 12.4 ± 1.2 minutes, 41.5 ± 3.8 minutes, 2.5 ± 0.6 times. In contrast, the TS group recorded 17.1 ± 1.5 minutes, 50.8 ± 3.4 minutes, and 3.3 ± 0.8 times, respectively (P <.001 for all). The 3DS group also achieved a more significant restoration of the IM angle (P < .001). Postsurgery, the 3DS group demonstrated superior outcomes in FM head lateralization, FM shortening, and plantar displacement (P <.001, P <.001 and P = .006, respectively, for all metrics). Only 1 patient in the 3DS group experienced a pin-tract infection, which was treated with wound care and oral antibiotics. CONCLUSION: Simulating surgery on a 3D model and using it as a guide significantly enhances surgical outcomes. Benefits include reduced operation time, tourniquet duration, decreased fluoroscopy usage, and improved first-ray alignment. The 3DS method also ensures better lateralization of the first metatarsal head and correction of the IM. Although 3D model-assisted HV chevron osteotomy surgery provides ideal deformity correction, it does not significantly affect postoperative functional outcomes.

OBJECTIVE: Chevron osteotomy offers near-excellent clinical results and adequate stability at lower shift percentages, among the techniques used to correct hallux valgus deformity. This cadaveric study aimed to compare the Chevron osteotomy with the reverse offset-L osteotomy, which may provide a greater surface area and a more stable geometry to withstand higher cantilever forces at higher shift percentages. METHODS: Metatarsal bones obtained from 20 human cadavers with similar bone quality were divided into two groups: Chevron osteotomy was applied to the 1st group and reverse offset-L osteotomy was applied to the 2nd group. The load-to-failure, displacement in the y-axis, and total displacement values of both groups were compared statistically. Furthermore, bone densities were compared between the groups with computed tomography imaging. RESULTS: When outliers in both groups were excluded, a statistically significant difference was found in favor of reverse offset-L (143 ± 42 vs. 204 ± 51.2 N, p = 0.02) in terms of failure load. The groups were similar in terms of displacement on the y-axis and total displacement values. Bone densities were similar. CONCLUSION: The reverse offset-L osteotomy has been shown to withstand greater loads before failure compared to the standard Chevron osteotomy. This significant difference in load-to-failure may enable reverse offset-L to provide reliable stability in osteotomies performed in advanced HV cases requiring higher shifts.

Dorsal cheilectomy refers to a surgical resection of the dorsal osteophyte from the first metatarsal head. It is most often performed in patients with hallux rigidus, who have little to no midrange pain of the first metatarsophalangeal joint. The procedure is simple, quick, and maintains range of motion. Additional advantages of this procedure include low morbidity, quicker postoperative recovery, avoidance of costly implants, and the fact that the procedure does not inhibit future conversion to an arthrodesis. These proposed advantages have led some authors to advocate for the use of a cheilectomy, even in patients with more extensive disease.

Objective: To compare the effectiveness of small incision external articular minimally invasive osteotomy and traditional Chevron osteotomy in the treatment of hallux valgus. Methods: A retrospective analysis was conducted on the clinical data of 58 patients (58 feet) with hallux valgus who were admitted between April 2019 and June 2022 and met the selection criteria. Among them, 28 cases were treated with small incision external articular minimally invasive osteotomy (minimally invasive group), and 30 cases were treated with traditional Chevron osteotomy (traditional group). There was no significant difference in baseline data such as age, gender, disease duration, Mann classification, and preoperative inter metatarsal angle (IMA), hallux valgus angle (HVA), distal metatarsal articular angle (DMAA), forefoot width, tibial sesamoid position (TSP) score, American Orthopaedic Foot and Ankle Society (AOFAS) forefoot score, visual analogue scale (VAS) score, psychological score (SF-12 MCS score) and physiological score (SF-12 PCS score) of short-form 12 health survey scale, and range of motion (ROM) of metatarsophalangeal joint between the two groups ( P>0.05). The incision length, operation time, intraoperative blood loss, intraoperative fluoroscopy frequency, weight-bearing walking time, fracture healing time, and incidence of complications were recorded and compared between the two groups; as well as the changes of imaging indexes at last follow-up, and the clinical function score and ROM of metatarsophalangeal joint before operation, at 6 weeks after operation, and at last follow-up. Results: All patients were followed up 11-31 months, with an average of 22 months. The incision length and intraoperative blood loss in the minimally invasive group were significantly less than those in the traditional group ( P<0.05), and the intraoperative fluoroscopy frequency and operation time in the minimally invasive group were significantly more than those in the traditional group ( P<0.05); but no significant difference was found in weight-bearing walking time and fracture healing time between the two groups ( P>0.05). There was 1 case of skin injury in the minimally invasive group and 3 cases of poor incision healing in the traditional group; all patients had good healing at the osteotomy site, and no complication such as infection, nerve injury, or metatarsal head necrosis occurred. At last follow-up, the imaging indexes of the two groups significantly improved when compared with those before operation ( P<0.05). The changes of DMAA and TSP score in the minimally invasive group were significantly better than those in the traditional group ( P<0.05), and there was no significant difference in the changes of IMA, HVA, and forefoot width between the two groups ( P>0.05). The clinical scores and ROM of metatarsophalangeal joint significantly improved in the two groups at 6 weeks after operation and at last follow-up when compared with preoperative ones ( P<0.05), and the indicators in the minimally invasive group were significantly better than those in the traditional group ( P<0.05). Conclusion: Compared with traditional Chevron osteotomy, small incision external articular minimally invasive osteotomy can effectively improve HVA, IMA, and forefoot width, correct foot deformities, and has less trauma. It can better correct the first metatarsal pronation deformity and restore the anatomical position of the sesamoid bone, resulting in better effectiveness.

BACKGROUND The Lisfranc ligament is crucial for maintaining the transverse and longitudinal arch of the foot. Owing to the disruption between the medial cuneiform bone and the base of the second metatarsal bone, the currently preferred fixation method remains controversial. Our fixation technique involves screwing one anchor to the medial and intermediate cuneiform bones and using the anchor to carry the ligament to bind the Lisfranc joint and first and second metatarsal joints altogether for elastic fixation. This study evaluated the clinical and functional outcomes of InternalBrace fixation for Lisfranc injury. MATERIAL AND METHODS This retrospective study included 58 patients who underwent InternalBrace fixation for Lisfranc injury between January 2019 and September 2022 by an experienced surgeon. One-way analysis of variance or t test was used. Preoperative classification was performed according to the Myerson classification with imaging data. Postoperative follow-up was performed based on intraoperative blood loss, fracture healing time, visual analog scale (VAS) score, the American Orthopedic Foot and Ankle Society (AOFAS) score, Tegner score, and complications. RESULTS Surgery was completed in all patients, and follow-up was performed. The patients' ages ranged from 19 to 62 years (average: 34.6±9.4 years). The postoperative follow-up time was 12-24 months (average: 16.9±3.0 months). The average time for fracture healing was 12.8±3.0 (10-24) weeks. The VAS, AOFAS, and Tegner scores significantly improved postoperatively (from 5.33±1.0 (3-7) to 1.24±0.57 (0-2); 28.02±6.70 (18-51) to 91.59±4.76 (82-96); and 2.40±0.67 (1-4) to 6.53±0.54 (6-7), respectively), which was statistically significant (P<0.01), and the good rate of AOFAS was 91.4%. The postoperative complications were traumatic arthritis, incision infection, and temporary dorsal foot numbness, which gradually recovered. No other rejection reactions or Lisfranc fracture/dislocations recurrence occurred during the follow-up period. CONCLUSIONS InternalBrace fixation for Lisfranc injury is beneficial for restoring Lisfranc joint stability and function and allows for early and more aggressive rehabilitation for patients, with fewer surgical complications.

OBJECTIVE: Minimally invasive stabilization of metatarsal fractures to enable adequate fracture healing in a correct position to restore anatomy and biomechanics of the foot. INDICATIONS: A. Dislocated diaphyseal and subcapital fractures of the second to fifth metatarsal (>â¯3â¯mm, >â¯10° dislocation). B. Fifth metatarsal fracture at the metadiaphyseal junction (Lawrence and Botte type III). CONTRAINDICATIONS: High grade soft tissue damage or infection at the implant insertion site. SURGICAL TECHNIQUE: A. Fluoroscopically assisted closed reduction and antegrade intramedullary fixation of diaphyseal and subcapital fractures of the second to fifth metatarsal. B. Fluoroscopically assisted wire-guided intramedullary screw fixation of fifth metatarsal fractures at the metadiaphyseal junction. POSTOPERATIVE MANAGEMENT: A. Mobilization with partial weight bearing (20â¯kg) for 6 weeks wearing a stiff sole; implant removal under local anesthesia after 6-8 weeks, followed by a free range of movement and weight-bearing as tolerated (WBAT). B. Early mobilization with weight-bearing as tolerated (WBAT); removal of the orthosis after 6 weeks, implant removal optional. RESULTS: A. Antegrade nailing of subcapital and shaft fractures of metatarsals II-V achieves good clinical results with low complication rates both when using prepared Kirschner wires or elastically stable intramedullary nails (ESIN). B. According to current literature, intramedullary screw osteosynthesis of proximal metatarsal V fractures of zone II and III according to Lawrence and Botte leads to faster bony healing with a lower nonunion rate compared with conservative treatment. It is recommended especially, but not only, for active athletes.

INTRODUCTION: Lisfranc joint injuries are common and often underdiagnosed. They occur during trauma of various mechanisms, high or low energy. Their management is difficult because of the wide spectrum of lesions and the management of associated lesions, particularly in the emergency stage. Their surgical treatment remains controversial. Therefore, the objective of this study was to evaluate and compare the management of Lisfranc injuries and to study their clinical, functional and radiologic evolution. We also wanted to assess the consequences of these lesions on the patient's quality of life. MATERIAL AND METHODS: This was a retrospective multicenter study of 141 patients over 16 years at the time of the trauma. The patients included had presented a Lisfranc injury from January 2010 to June 2018. The epidemiological characteristics, the type of osteosynthesis, and the immediate and radiographic results at the last follow-up were collected. Functional assessment was analyzed by telephone review using the SF12, FAAM and AOFAS scores. RESULTS: An associated M2 base fracture was found in almost 50 % of cases. A closed reduction and fixation was made in 25 % of cases. There was 69 % pins fixation. The reduction was not anatomical in 1/3 of the cases and was more difficult to achieve with an associated fracture. The FAAM score was statistically superior in the patients with internal fixation by screws compared to the treatment by pins. We found 18 % early complications. At least 1 year after the injury, C2M2 osteoarthritis was found in 45 % of patients. DISCUSSION: Contrary to what is recommended in the literature, this study reported a high rate of osteosynthesis by pins whereas screws and plates were more recommended. Open reduction was also recommended and was the strategy of choice in this study. An M2 fracture was often associated with Lisfranc dislocations. The quality of reduction was essential and was better with open reduction and screw fixation.

PURPOSE: To date, the surgical treatment of severe hallux valgus deformity remains challenging despite the various methods presented. This study aimed to compare the effectiveness of minimally invasive distal chevron Akin osteotomies (d-MICA) and minimally invasive proximal chevron Akin osteotomies (p-MICA) in correcting severe hallux valgus deformities. METHODS: This prospective follow-up study included patients randomly assigned to undergo p-MICA or d-MICA for hallux valgus deformities with a preoperative hallux valgus angle (HVA) ≥ 40° and/or a first to second intermetatarsal angle (IMA) ≥ 16°. After a minimum follow-up period of two years, we compared various clinico-radiographic parameters of patients whose HVA exceeded 15° at the final follow-up. RESULTS: In the p-MICA and d-MICA groups, seven of 40 cases (17.5%) and 16 of 41 cases (39.0%), respectively, exhibited HVA > 15° at the final follow-up (P = 0.048). The preoperative parameters showed no significant differences. However, at the first weight-bearing assessment, the HVA, IMA, and relative second metatarsal length were significantly smaller, and the distal metatarsal articular angle (DMAA) was greater in the p-MICA group (all P < 0.05) compared with the d-MICA group. Postoperatively, both groups exhibited significant decreases in HVA and IMA at the final follow-up (P < 0.001 for all parameters). The p-MICA group showed no significant changes in DMAA and the relative length of the second metatarsal (P = 0.253 and 0.185, respectively). However, the d-MICA group showed a significant decrease in DMAA (P < 0.001) and an increase in the relative length of the second metatarsal at the final follow-up (P = 0.01). CONCLUSIONS: p-MICA and d-MICA procedures demonstrated effective correction potential for severe hallux valgus deformities; however, the d-MICA procedure exhibited a notably higher incidence of unsatisfactory correction at the final follow-up than p-MICA. Therefore, d-MICA may be less predictable in achieving successful outcomes than p-MICA in treating severe hallux valgus deformities.

Metatarsal fractures are some of the most common fractures reported in the human body. Recent advances in surgical techniques and fixation have helped facilitate healing and improved outcomes for our patients. The treatment goals of metatarsal fractures are to maintain the metatarsal parabola, sagittal position of the metatarsal heads, and a congruent metatarsophalangeal joint. Most of these injuries can be treated nonoperatively, but displaced fractures require surgical intervention to preserve normal gait biomechanics.

Lisfranc injuries were thought to primarily occur during high-energy events, leading to a preference for fusion treatment; however, recent data have shifted this perspective by highlighting a greater occurrence of low-energy injuries and reshaping the focus on open reduction internal fixation. This multifaceted process is guided by various factors, including the nature of the injury, specific anatomic considerations, and the involved joints. Our overarching goal remains to achieve anatomic reduction, with flexibility in hardware fixation methods. In cases of comminution, bridge plating may be warranted, potentially followed by arthrodesis in the future.

BACKGROUND: In the literature, there is no consensus regarding the surgical management of postaxial polydactyly, and few cases of polymetatarsia with polydactyly have been reported. Treatment of the complete deformity will prevent further foot and gait disorders. OBJECTIVE: To identify literature relevant to the operative management of Y-shaped metatarsal with biphalangeal sixth toe and related skin and wound care to improve surgical treatment protocols from a clinical experience perspective. DATA SOURCES: The authors searched several electronic databases in December 2022 for articles related to postaxial polysyndactyly in the feet and polymetatarsia. Databases searched included PubMed, SciELO, ScienceDirect, Cochrane Database of Systematic Reviews, and Google Scholar gray literature. STUDY SELECTION: Two independent researchers conducted the searches and read the article titles and abstracts. Studies were included if they were narrative reviews, case studies, or observational studies; written in English or Spanish; and published between 2012 and 2022. Nonhuman studies were excluded. Studies that met the inclusion criteria were fully evaluated. Disagreements between reviewers were resolved by consensus, and when there was no consensus, a senior researcher was consulted. DATA EXTRACTION: The following data were extracted from the included studies using a standardized form: author and year of publication, study type, number of participants, sex, polydactyly location, polymetatarsia, type of polydactyly, participants' history of hereditary associated diseases or malformations, treatment, removal criteria, and timing of surgery. DATA SYNTHESIS: Authors evaluated 11 studies of postaxial polydactyly that included a total of 153 participants (64 men, 89 women). They also document their clinical experience with a surgical technique used in cases of bilateral postaxial polydactyly of the foot with a Y-shaped metatarsal with biphalangeal sixth toe. CONCLUSIONS: Surgical correction with lateral removal of the sixth toe is a resolutive treatment to improve the functionality of the foot, its aesthetic appearance, and the patient's quality of life. Case-specific treatment should be applied and tailored to meet the individual needs. The biomechanics of gait and shoe problems in these patients improve with surgical treatment, without presenting secondary aesthetic problems in skin care.

BACKGROUND: The traditional scarf osteotomy (TSO) has limited ability to correct the first metatarsal pronation. A novel modification that we refer to as a "dovetailed notch scarf osteotomy" (DNSO) has been developed to enhance the ability to correct coronal plane pronation. The study aimed to observe and compare TSO to DNSO in the treatment of moderate to severe hallux valgus deformity. METHODS: This retrospective study included 78 feet that had a TSO and 105 feet that had a DNSO. Minimum follow-up was 24 months. Weightbearing computed tomography (WBCT) and weightbearing anterior-posterior (AP) radiographs were taken preoperatively and at the last follow-up. We measured the intermetatarsal angle (IMA), hallux valgus angle, distal metatarsal articular surface angle on AP radiographs and first metatarsal coronal pronation angle (α angle), tibial sesamoid coronal grading, and first metatarsal length on WBCT. Clinical assessment was done using visual analog scale (VAS), American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot scale, Foot and Ankle Ability Measure (FAAM), and the 36-Item Short Form Health Survey (SF-36). The occurrence of postoperative complications was also documented. RESULTS: The DNSO group exhibited a significantly higher correction amount of α angle and IMA (14.3 ± 9.9 and 10.3 ± 4.6 degrees) than the TSO group (8.6 ± 5.9 and 5.4 ± 5.9 degrees) during the final follow-up assessment (P < .05).The DNSO group (10.1 [8.0-12.0] degrees and 4.8 [3.9-5.6] degrees) demonstrated significantly smaller α angle and IMA compared with the TSO group (4.8 [3.9-5.6] degrees and 9.5 [7.5-11.5] degrees) at 24 months postsurgery (P < .05). The postoperative FAAM activities of daily living and SF-36 physical functioning scores were significantly higher in the DNSO group (97.2 ± 3.3 and 95.7 ± 4.4 points) compared with the TSO group (92.3 ± 3.3 and 87.7 ± 8.7 points) (P < .05). Additionally, hallux varus occurred in 1 case in the DNSO group, whereas 4 cases were observed in the TSO group. CONCLUSION: Two osteotomy methods can effectively correct moderate to severe hallux valgus deformity. Compared with the TSO, the DNSO has stronger correction ability. The most crucial aspect lies in its controllability when correcting first metatarsal pronation and addressing IMA. LEVEL OF EVIDENCE: Level III, retrospective comparative study.

BACKGROUND: The surgical treatment of hallux valgus (HV) deformity has been the subject of countless publications but few focus on the altered windlass mechanism or analyze the biomechanical behavior immediately after surgery. METHODS: Patients treated for HV between January and March 2023 were included. The surgery consisted of a L-reverse first metatarsal osteotomy. To analyze the windlass mechanism we record two different measurements; the isolated first metatarsophalangeal joint (MTPJ) dorsiflexion angle (IDA) and dynamic plantarization of the first metatarsal head when performing first MTPJ dorsiflexion imprinting a mark on a modeling foam. RESULTS: A total of 30 patients diagnosed with symptomatic HV were included. In all patients, a change in the IDA angle was evident, being overall statistically significant. About modeling foam imprinted mark, all measurements, in all planes of space, had a clear tendency to increase, which turned out to be statistically significant (p < 0.001). CONCLUSIONS: An altered windlass mechanism may be successfully recovered immediately after hallux valgus deformity surgery. This could be evinced by an indirect measurement analyzing the imprint of the head of the first metatarsal in a modeling foam and the IDA. LEVELS OF EVIDENCE II: None.

BACKGROUND: Hallux valgus (HV) is a very common deformity worldwide. Most of the surgical techniques used in the treatment of HV only correct these deformities in two planes, that is sagittal and transverse planes. The importance of the first metatarsal pronation as an etiological factor of hallux valgus is validated by numerous authors and it is usually unaddressed. Few surgical techniques have focused on the correction of rotational deformity of the hallux valgus. We aim to first report a detailed technique and a case series using the Distal Rotational Metatarsal Osteotomy (DROMO) surgical technique, which is less invasive and can address the pronation deformation. METHODS: The inclusion period was 6 months finishing in April 2021. The study analyzed the following x-ray parameters: preoperative and postoperative intermetatarsal angle (IMA), preoperative and postoperative hallux valgus angle (HVA), preoperative and postoperative coronal rotation of the first metatarsal according Hardy and Clapham's classification as described by Kim et al., preoperative and postoperative shape of the first metatarsal head as described by Ono et al. RESULTS: 33 patients matched our inclusion and exclusion criteria. Most patients underwent the surgery for the left foot (n = 18), compared to the right foot (n = 15). We found statistically significant differences between preoperative and postoperative IMA (p < 0.001), preoperative and postoperative HVA (p < 0.001). Preoperative and postoperative coronal rotation of the first metatarsal as classified by Hardy and Clapham was significantly different (p < 0.001), as well as preoperative and postoperative shape of the first metatarsal head (p < 0.01). CONCLUSIONS: DROMO can correct the metatarsal rotation through minimal invasive surgery. From our perspective, DROMO technique should be another alternative for HV correction technique which in time can be associated as a local anesthetic technique, DROMO results are attractive for an ambulatory procedure.

Background: Jones fractures are common injuries that can be treated conservatively or surgically. However, the optimal treatment approach remains controversial. This study aimed to compare the clinical outcomes of conservative and operative treatments for Jones fractures and determine whether surgical treatment is necessary. Methods: A retrospective study was conducted on 69 patients with Jones fractures treated at our hospital. The patients were divided into 2 groups: conservative (C group; n = 46) and operative (O group; n = 23) treatments. Patients were followed up after 2, 6, and 12 weeks, and every 3 months thereafter. However, outpatient follow-ups were conducted between 8 and 10 weeks as needed. The mean follow-up period was 14.5 weeks (range, 12-24 weeks). In group C, the patients were treated with a non-weight-bearing cast for 4-6 weeks, followed by additional weight-bearing boot immobilization before returning to exercise. In group O, patients were treated surgically using a bicortical screw or intramedullary internal fixation. Time to radiologic union, clinical union, return to sports, visual analog scale (VAS), Foot Function Index-Revised Short Form (FFI-RS), and American Orthopedic Foot and Ankle Society (AOFAS) scores were evaluated. Results: Sixty-nine patients were included in the analysis. There were statistically significant differences in the time to radiologic union and return to sports, VAS score in the second week, and FFI-RS score in the 12th week. In group C, favorable outcomes were observed in terms of the time to return to sports, VAS score in the second week, and FFI-RS score in the 12th week. Contrastingly, in group O, better results were observed in time to radiologic union. The AOFAS score was excellent at the final follow-up, with no significant differences between groups. Complication rates were 10.8% and 13% in groups C and O, respectively. Conclusions: Surgical treatment is sometimes necessary for Jones fractures, but conservative treatment should also be considered because of the favorable outcomes. Conservative treatment can be a good option for patients who are risk-averse and place a high value on fracture healing without surgery.

Objective: To explore the effectiveness of transverse double "8"-shaped tension band technique in the treatment of Lawrence zoneâ fracture of the 5th metatarsal base. Methods: Between February 2019 and October 2021, 15 patients with Lawrence zoneâ fracture of the 5th metatarsal base were treated with transverse double "8"-shaped tension band technique. There were 8 males and 7 females, with a median age of 40 years (range, 23-59 years). The fractures were caused by sprains. The time from injury to operation was 3-7 days (mean, 4.1 days). X-ray films were taken to observe the fracture healing and the anchor looseness and detachment. The foot function was evaluated by American Orthopaedic Foot and Ankle Society (AOFAS) score, visual analogue scale (VAS) score, and the eversion angle of the calcaneal talus joint. Results: The incisions healed by first intention after operation in 14 cases and the incision healed poorly in 1 case. All patients were followed up 8-12 months (median, 10 months). The imaging examination showed that all fractures healed well, with a healing time of 10-14 weeks (mean, 11.7 weeks). At last follow-up, AOFAS score was 82-100 (median, 98); 13 cases were excellent and 2 cases were good, with an excellent and good rate of 100%. VAS score was 0-3 (median, 1). Three cases had mild limited ankle joint range of motion, while 12 cases had normal range of motion. The eversion angle of the calcaneal talus joint was 25°-32° (median, 30°). Conclusion: The application of transverse double "8"-shaped tension band technique for Lawrence zone â fracture of the 5th metatarsal base has advantages such as simple operation, avoidance of secondary operation, and reduction of foreign body sensation, with definite effectiveness.

BACKGROUND: There is no consensus whether the primary surgical method should be open reduction and internal fixation (ORIF) or primary arthrodesis (PA) for Lisfranc injuries. The aim of our randomized controlled trial was to compare ORIF and PA for displaced Lisfranc injuries. METHODS: This study was a national multicenter randomized controlled trial. Altogether 43 displaced Lisfranc injuries were enrolled in this trial. The primary outcome measure was Visual Analogue Scale Foot and Ankle (VAS-FA) at a 24-months follow-up. The secondary outcome measures were VAS-FA pain, function, and other complaints subscales and the American Orthopaedic Foot & Ankle Society (AOFAS) Midfoot Scale. All outcomes were measured at 6, 12, and 24 months. We were unable to reach the planned sample size of 60 patients; thus, the study remains underpowered. RESULTS: The mean VAS-FA Overall score in the ORIF group was 86.5 (95% CI 77.9, 95.1) and 80.1 (95% CI 72.0, 88.1) in the PA group at the 24-month follow-up. We did not find eligible evidence of a difference in VAS-FA Overall scores (mean between-group difference 6.5 [95% CI -5.3, 18.2], Cohen d = 0.100). CONCLUSION: We did not find evidence of a difference in VAS-FA between ORIF and PA in patients with displaced Lisfranc injuries, and thus both are viable options for the initial surgical method. The trial is underpowered; however, the data may be included in a meta-analysis of similarly designed randomized controlled trials.ClinicalTrials.gov identifier: NCT02953067 24 October 2016.

PURPOSE: The primary aim is to assess the efficacy of the surgical callus distraction technique of the metatarsus in paediatric patients. Secondary objectives are to assess complications and treatment duration. We have also described the details of our surgical technique. MATERIALS AND METHODS: A case series review of paediatric patients who had metatarsal lengthening at our unit between 2014 and 2022. Patient demographics, duration of time in frame, complications and metatarsal length achieved were recorded. The AOFAS Midfoot and the MOXFQ were taken pre-operatively and at final follow-up. RESULTS: Sixteen metatarsals in 8 patients (14 feet) underwent lengthening between 2014 and 2022 using the MiniRail OrthoFix 100 (Orthofix Medical Inc, Lewisville, TX, USA). The mean age was 13.3 (12-17) years. The average duration between surgery and implant removal was 5.2 months. According to Paley's classification, there was one obstacle encountered in a patient who required a revision of their osteotomy and one problem in another patient who had an infected metatarsophalangeal joint stabilising k-wire treated with oral antibiotics. The Mean AOFAS Midfoot score improved from 53.10 to 86.40 (p < 0.0001) and the Mean MOXFQ improved from 32.5000 to 12.1250 (p < 0.05); these were statistically significant. CONCLUSION: Gradual metatarsal lengthening using the MiniRail external fixator is a safe and effective method to treat brachymetatarsia in paediatric patients. This preliminary report describes and supports metatarsal lengthening in appropriate patients. Holistic care in terms of a pre-operative assessment, psychological support and preparation for the extended rehabilitation period are vital.

BACKGROUND: Plantar transfer ulcers (TUs) underneath the second metatarsal head are frequent after first metatarsal ray amputations due to diabetic foot infections. Whether the second metatarsal length (2ML) is associated with TU occurrence in these patients is unclear. This study evaluated whether 2ML is associated with TU occurrence after first-ray amputations and whether ulcer-free survival is shorter in patients with "excess" 2ML. METHODS: Forty-two patients with a mean age of 67 (range 33-93) years, diabetes, and first metatarsal ray amputation (first amputation at the affected foot) were included. Two independent readers measured the 2ML using the Coughlin method. A protrusion of more than 4.0 mm of the second metatarsal was defined as "excess" 2ML. The effect of 2ML on ulcer occurrence was analyzed using a multivariate Cox regression model. A Kaplan-Meier curve for TU-free survival was constructed comparing the 2 groups of "normal" (n = 21) and "excess" 2ML (n = 21). RESULTS: Interrater reliability was excellent. TUs underneath the second metatarsal occurred in 15 (36%) patients. In agreement with our hypothesis, 2ML was nonsignificantly different in patients with TUs, recording a mean of 5.3 (SD 2.5) mm, compared to patients without 4.0 (SD 2.3) mm (hazard ratio [HR] 1.12, 95% CI 0.89-1.41), whereas insulin dependence was associated with ulcer occurrence (HR 0.33, 95% CI 0.11-0.99). CONCLUSION: In our relatively small study population with a cutoff level of 4 mm for excess 2ML, ulcer-free survival was similar in patients with "normal" and "excess" 2ML. LEVEL OF EVIDENCE: Level III, retrospective comparative study.
