RESUMO

OBJECTIVE: Given the ability of ultrasound imaging (USI) to depict tissue-specific morphological changes before the onset of pain and before the point of irreversible structural damage, USI could play a fundamental role in earlier detection and assessment of foot osteoarthritis (OA). The current guidelines require further refinement of anatomical landmarks to establish a standardized imaging procedure to improve the interpretability and reproducibility between studies evaluating the first metatarsophalangeal joint (MTPJ). The aims were to develop an USI acquisition procedure and grading system to examine OA features in the first MTPJ and to determine intra-examiner and inter-examiner reliability of a newly developed USI acquisition procedure. DESIGN: Thirty participants with first MTPJ OA confirmed radiographically with the use of the La Trobe Foot Atlas were included. An experienced sonographer applied a newly developed USI procedure to examine the following features: joint effusion, synovial hypertrophy, synovitis, joint space narrowing, osteophytes, and cartilage thickness. A semiquantitative grading system was applied to all features. A continuous measure was also examined for osteophyte size, joint space narrowing, and cartilage thickness. To determine the intra-examiner and inter-examiner reliability, an experienced radiologist and sonographer applied the developed grading system to the images acquired from two imaging sessions. Intra-examiner and inter-examiner reliability were calculated using intraclass correlation coefficients (ICCs). RESULTS: ICCs for intra-examiner between session reliability ranged from 0.58 to 0.92 for semiquantitative grading and 0.39 to 0.94 for continuous measures. Joint effusion and osteophytes achieved the highest intra-examiner reliability (ICC = 0.78-0.94). ICCs for session one inter-examiner reliability ranged from 0.61 to 1.0 for semiquantitative grading; all continuous measures had an ICC of 1. ICCs for session two inter-examiner reliability ranged from 0.55 to 1.0 for semiquantitative grading and 0.9 to 0.97 for continuous measures. Inter-examiner reliability was good for grading joint effusion (ICC = 0.55-0.62) and was excellent for all other USI features (ICC = 0.77-1.0). CONCLUSION: The USI acquisition procedure and grading system are reliable in evaluating first MTPJ OA features in participants with radiologically confirmed OA. The study will inform the methodological development of an ultrasound atlas for grading the degree of osteoarthritic change in the first MTPJ.

RESUMO

Hyperextension of the first metatarsophalangeal joint can lead to a turf toe injury of the plantar plate complex, resulting in significant morbidity for athletes. This article reviews the anatomy, pathophysiology, classification, and imaging findings of turf toe injuries. In turf toe trauma, many different structures can be injured, with the sesamoid-phalangeal ligaments the most common. Diagnosis, classification, and treatment options rely on clinical evaluation and specific magnetic resonance imaging findings. It is vital for radiologists to understand the anatomy, pathophysiology, and imaging findings of turf toe injuries to ensure an accurate diagnosis and appropriate management.

RESUMO

The main object of this prospective cohort study was to compare surgical treatment options for primary metatarsalgia and the severe instability of lesser metatarsophalangeal joints. The outcomes of triple Weil osteotomy combined with direct plantar plate repair and triple Weil osteotomy, performed with proximal interphalangeal joint arthrodesis, are analyzed and compared. One hundred thirteen patients (117 feet) were enrolled in the study. They were split into 2 groups. In the first group, undergoing Weil osteotomy, combined with the plantar plate repair, good results, including complete pain reduction, elimination of hyperkeratosis, and American Orthopedic Foot and Ankle Society Score improvement, were achieved in 84.7% of the cases. The second group, where the combination of Weil osteotomy and proximal interphalangeal joint K-wire arthrodesis was used, demonstrated good results in 52.4% of the cases. Weil osteotomy, combined with the plantar plate repair, achieves better results in comparison to osteotomy, performed with the interphalangeal joint arthrodesis.

RESUMO

The use of staples has been shown to be a reasonable fixation technique to achieve stability of a first MTPJ arthrodesis. Although it has been shown to be a weaker construct than crossed screws or plate and screw combinations, their ease of insertion, low profile, and stability make them a desirable choice for first MTPJ arthrodesis fixation. However, because of this relative weakness, the question remains whether immediate weightbearing when using staples is advisable. The aim of this study is to determine whether the use of 2 nickel-titanium alloy (NITINOL) staples, placed at 90 degrees to one another is a stable enough construct to support full, immediate weightbearing following first MTPJ arthrodesis. We performed a retrospective chart review of patients undergoing first MTPJ arthrodesis by a single surgeon utilizing 2 NITINOL staples placed at 90 degrees to one another. Patients were allowed to be fully weightbearing immediately postoperatively. Forty-seven of 50 (94%) patients achieved complete radiologic consolidation of fusion at 12 weeks, with only 3 requiring revision surgery for nonunion. All of the patients requiring revision surgery for nonunion, had preoperative diagnosis of hallux abducto valgus. We concluded that the use of 2 NITINOL staples placed at 90 degrees to one another is a viable option for first MTPJ arthrodesis, and immediate weightbearing does not increase rate of nonunion or incidence of revision surgery when compared to other fixation techniques.

RESUMO

The purpose of this study was to explore the difference between congruency and incongruency of the first metatarsophalangeal (MTP) joint in hallux valgus using weightbearing CT (WBCT) and to identify the risk factors for incongruency. From January 2019 to January 2021, WBCT scans were retrospectively analyzed for 110 (191 feet) consecutive patients. According to whether the metatarsal articular surface and phalanx articular surface were parallel, they were divided into congruency (73 feet) and incongruency groups (118 feet). The age, intermetatarsal angle (IMA), hallux valgus angle (HVA), distal metatarsal articular surface angle (DMAA), first metatarsal coronal pronation angle (α angle), tibial sesamoid 7 positions (TSP), and tibial sesamoid coronal grading (TSCG) were compared between the 2 groups. Binary logistic regression was used to analyze the influencing factors of incongruency. Receiver operating characteristic (ROC) curve analysis was applied to determine the cutoff value. There were significant differences in IMA, HVA, DMAA, α angle, age, TSP, and TSCG between congruency and incongruency groups (p < .05). Binary logistic regression analysis showed that TSCG, HVA, α angle were the influencing factors of incongruency. ROC curve analysis demonstrated that the cutoff values for incongruency were 1 position for TSCG (sensitivity: 0.835; specificity: 0.884) with the area under curve (AUC) of 0.892, 30° (sensitivity: 0.795; specificity: 0.812) for HVA with the AUC of 0.878, and 24° (sensitivity: 0.530; specificity: 0.797) for α angle with the AUC of 0.686. Incongruency of the first MTP joint indicated a more severe hallux valgus, and was associated with increased HVA, α angle, and TSCG.

RESUMO

OBJECTIVE: We aimed to explore the relationship between bone shape and radiographic severity in individuals with first metatarsophalangeal joint osteoarthritis (first MTP joint OA). METHODS: Weightbearing lateral and dorsoplantar radiographs were obtained for the symptomatic foot of 185 participants (105 females, aged 22 to 85 years) with clinically diagnosed first MTP joint OA. Participants were classified into none/mild, moderate, or severe categories using a standardized atlas. An 80-point model for lateral radiographs and 77-point model for dorsoplantar radiographs was used to define independent modes of variation using statistical shape modeling software. Odds ratios adjusted for confounders were calculated using ordinal regression to determine the association between radiographic severity and mode scores. RESULTS: After assessment and grading of radiographs, 35 participants (18.9%) were included in the none/mild first MTP joint OA severity category, 69 (37.2%) in the moderate severity category, and 81 (43.7%) in the severe category. For lateral-view radiographs, 16 modes of variation were included, which collectively represented 83.2% of total shape variance. Of these, four modes were associated with radiographic severity. For dorsoplantar-view radiographs, 15 modes of variation were included, representing 82.6% of total shape variance. Of these, six modes were associated with radiographic severity. CONCLUSIONS: Variations in the shape and alignment of the medial cuneiform, first metatarsal, and proximal and distal phalanx of the hallux are significantly associated with radiographic severity of first MTP joint OA. Prospective studies are required to determine whether bone shape characteristics are associated with the development and/or progression of this condition.

RESUMO

Hammertoes with greater preoperative transverse plane deformity are more likely to recur after corrective surgery; however, it is unclear whether this represents an inherent (fixed, nonmodifiable) risk, or whether steps can be taken intraoperatively to mitigate this risk. In this study, we examined whether transverse plane transposition and/or shortening of the second metatarsal during second hammertoe surgery influenced recurrence. We performed a secondary analysis of pre-existing data from patients that had previously undergone second hammertoe surgery at our institution between January 1, 2011 and December 31, 2013. One hundred two patients (137 toes) were followed for a mean 28 ± 7.8 months postoperatively. Thirty-seven toes required, at the surgeon's discretion, an additional/concomitant Weil metatarsal osteotomy. Magnitude of transverse plane transposition and shortening of the second metatarsal, and joint angular measurements were obtained from the second metatarsophalangeal joint on weightbearing AP radiographs preoperatively and at 6 to 10 weeks postoperatively. Cox regression analysis was used to identify predictors of hammertoe recurrence using these new variables and a set of known predictors. In the final regression model, failure to establish a satisfactory postoperative metatarsal parabola (i.e., long second metatarsal; Nilsonne values <-4 mm, multivariate hazards ratio [HR] 1.96, p = .097), and intraoperative lateral transposition of the metatarsal head (multivariate HR 3.45, p = .028) seemed to confer additional risk for hammertoe recurrence. We conclude that shortening osteotomies may be assistive in some individuals, while further inquiry is still needed to determine whether similar benefits can be derived from medial head transposition in medial toe deformities.

RESUMO

Hyperflexion injury to the metatarsophalangeal joint of the great toe, referred to as sand toe, can cause significant functional impairment. To our knowledge, there have been no radiological descriptions of this injury in the paediatric age group. Here, we report radiographic, sonographic and MRI findings in a male paediatric patient who sustained a sand toe injury, highlighting structural damage to the dorsomedial capsule and medial sagittal band, and discuss sand toe's favourable prognosis with conservative management.

RESUMO

This case presents a known complication of particulate synovitis granuloma associated with a first metatarsophalangeal joint silastic implant. However, the degree of soft tissue granuloma enlargement is quite unique in size and its proliferative effect-invading the medulla cavity and infiltrating the outer cortex of bone. This case study aims to demonstrate its clinical presentation, imaging investigations, surgical excision and histopathology findings. The learning points emphasised within this manuscript draw attention to the procedure selection for a silastic implant, as well as its proposed mode of action and various potential associated complications. Surgery was based on careful analysis of overall function, prior surgery conducted and patient expectations to achieve a shared decision-making process.

RESUMO

Turf toe injuries are common, particularly in athletes competing on artificial turf. This debilitating injury and its associated sequelae can affect the long-term performance of athletes and others. In this case is presented an atypical cause for development of grade III turf toe. This case presents an acute injury with significant damage to the plantar first metatarsophalangeal joint, with plantar plate rupture and tibial sesamoid retraction secondary to injury involving working calves on a ranch. The anatomy, mechanism, and associated treatments are reviewed. The anatomical and functional interplay with this injury is discussed.

RESUMO

Fusion of the first metatarsophalangeal joint (MTPJ) is a commonly performed surgical procedure. Although the effect of first MTPJ fusion on reduction of Intermetatarsal angle (IMA) is well described, contributing factors remain unclear. The aim of this study was to identity predictive parameters for IMA reduction. Fifty-one patients (68 feet) who underwent a first MTPJ fusion and had an IMA greater than fourteen degrees were assessed retrospectively. The average age was 68 (31.4-79.3) years. Sixteen demographic and radiographic variables were evaluated using a multivariate regression analysis for association with change in IMA after surgery. The mean preoperative IMA was 16.11 (range, 14.0-22.5) degrees with a mean reduction of 4.95 (range, 0-17) degrees after surgery. Multivariate regression analysis revealed three significant independent predictors of the change in IMA. Increased preoperative IMA (ß = .663, CI = .419, .908, P <.001), increased preoperative translation at base of MT1 (ß = .490, CI = 0.005, .974, P = 0.039), and less postoperative translation in the fusion (ß= -0.693, CI= -1.054, -.331, P= 0.002) significantly increased the amount of IMA reduction. Pre-operative IMA and translation at the base of the first metatarsal were positive predictors for correction of IMA after first MTPJ fusion. Translation at the level of the MTP I fusion was a negative predictor for the amount of IMA correction. Based on these findings, we recommend minimizing the lateral translation of the proximal phalanx relative to the metatarsal head to optimize IMA correction after MTPJ fusion.

RESUMO

Irrespective of the exceptional adaptation of dromedaries to harsh environmental conditions, they remain highly susceptible to joint lameness resulting from a range of diverse factors and conditions. The joints most often affected by traumatic osteoarthritis in dromedaries are the metacarpophalangeal and metatarsophalangeal joints. A comprehensive understanding of joint anatomy and topography of the dromedary is required to perform arthrocentesis correctly on affected joints. Forty-two distal limbs were taken from 28 camels and studied by gross dissection, casting, ultrasonography, and computed tomography (CT). Representative three-dimensional models of the joint cavities, recesses, and pouches were obtained using different casting agents. This study provides a detailed description of dorsally, axially, and abaxially positioned joint recesses, as well as palmar/plantar positioned joint pouches. The safety and feasibility of the different arthrocentesis approaches were evaluated. The traditional dorsal arthrocentesis approach of the metacarpophalangeal, metatarsophalangeal, proximal interphalangeal, and distal interphalangeal joints, has limitations due to the risk of damaging the tendon structures and articular cartilage, which can lead to joint degeneration. A lateral arthrocentesis approach via the proximal palmar/plantar pouches of the metacarpophalangeal/metatarsophalangeal and proximal interphalangeal joints is recommended. This approach eliminates the potential needle injury to the articulating joint cartilage and other surrounding joint structures, such as tendons, blood vessels, and nerves.

RESUMO

First metatarsophalangeal joint (MPJ) arthrodesis procedures are a mainstay of forefoot surgery and are associated with high rates of patient satisfaction for addressing a multitude of first ray pathologic conditions. This procedure is often also used as a fallback option for the revision of poor outcomes after other surgical procedures involving the first ray. Despite its successes, there remain instances of complications that can develop after primary first MPJ arthrodesis. This article reviews first MPJ arthrodesis as a procedure for revisional surgery of the first ray, and potential surgical options after failed primary first MPJ arthrodesis.

RESUMO

BACKGROUND: Hallux interphalangeal joint arthrodesis (HIPJA) is indicated for a variety of pathologies. Despite high nonunion rates, techniques remain unchanged. The aim of this study is to examine nonunion and complication rates and describe risk factors for treatment failure. METHODS: A query of an institutional database was performed to identify all patients undergoing HIPJA procedure over a 10-year period. Records were reviewed to the procedure, evaluate patient factors, indications, and radiographic/clinical arthrodesis. Radiographic union was defined as 2 cortical continuations or bridging at the arthrodesis site, absence of hardware failure, and the absence of lytic gapping of the arthrodesis. Clinical fibrous union was defined as radiographic nonunion with painless toe range of motion and physical examination consistent with fusion across the interphalangeal joint. RESULTS: Two hundred twenty-seven primary HIPJA procedures were identified. Our cohort demonstrated a 25.5% nonunion rate (58/227) and 21.1% reoperation rate (48/227). Patients with diabetes were at higher risk for nonunion (P = .014), but no significant differences were identified based on smoking status or diagnosis of inflammatory arthritis. No difference was seen between implant groups: single screw, multiple screws, screw plus other fixation, nonscrew fixation. Patients with prior hallux metatarsophalangeal joint arthrodesis did not have a significantly higher nonunion rate than patients without prior first metatarsophalangeal joint arthrodesis. Patients diagnosed with radiographic nonunion were at higher risk for reoperation (P < .0001). CONCLUSION: Our cohort represents the largest single-center series of HIPJA procedures published to date. We found relatively high nonunion and reoperation rates with standard current techniques. LEVEL OF EVIDENCE: Level III, retrospective case series.

RESUMO

Injuries to the plantar plate complex of the first toe and the lesser toes, although closely related anatomically, differ significantly in their pathogenesis. Lesser metatarsophalangeal joint plantar plate degeneration and tear typically presents as an attritional pattern of capsuloligamentous deficiency in middle-aged patients, whereas first metatarsophalangeal joint capsuloligamentous injury is typically acute and occurs in younger adult athletes engaged in sports involving repetitive running and jumping. Consequently, considerations regarding surgical decision-making also differ. Knowledge of the anatomy, pathophysiological basis, common patterns, grading and classification of these injuries, and indications for surgery, will aid imaging interpretation in the preoperative setting. The acuity and extent of injury, tissue quality and functional requirements of the patient (such as timely return to sport) influence clinical decision-making with respect to conservative versus surgical management and are informed by the use of optimized multimodal imaging. This section will provide an overview of these injuries in 2 parts, separated into those affecting the first toe and the lesser toes, and will highlight imaging findings relevant to surgical decision-making.

RESUMO

OBJECTIVE: To examine the presence of certain shapes of the first metatarsal-cuneiform joint (MTC) joint in feet with hallux valgus (HV) deformity. To determine whether the anatomical orientation of this joint affects the size of the hallux valgus angle (HVA) and the first intermetatarsal angle (IMA) and whether it contributes to the dynamics of the developmental course of HV deformity. METHODS: The shape of the first MTC joint was determined on a sample of 315 feet with HV deformity. The influence of the shape of this joint on the values of HVA and IMA was explored. The relation between the position of the tibial sesamoid and the size of HVA and IMA as well as the dynamics of the development of this deformity depending on the shape of the first MTC joint, was examined. RESULTS: The oblique shape of the first MTC joint was found in 165 (52.4%) feet, the transverse in 145 (46%), and the convex shape was registered in five feet (1.6%). In the oblique shape of this joint, a moderate and severe degree of HV deformity is predominant, while in the transverse shape a mild degree dominates. A statistically significant dependence of HVA on the shape of the first MTC joint was found (Sig. = 0.010), while the dependence of IMA did not show statistical significance (Sig. = 0.105). HVA values follow the position of the tibial sesamoid in both shapes of the MTC joint while the size of the IMA in the transverse shape does not follow the change of the position of this sesamoid. CONCLUSION: The oblique shape of the first MTC joint is associated with the more severe form of HV deformity and its faster developmental course. In the analyzed sample, it was shown that HVA is higher in the oblique shape of the MTC joint and significantly depends on the anatomical orientation of this joint. Furthermore, IMA has a higher value in the oblique shape compared to transverse but this dependence is not statistically significant. The analysis showed that the oblique shape of the first MTC joint contributes to the development of HV deformity.

RESUMO

OBJECTIVES: To compare if the 4th and 5th metatarsophalangeal (MTP) joints evaluated by high-resolution peripheral quantitative computed tomography (HR-pQCT) could classify more patients with erosive rheumatoid arthritis (RA) compared with conventional radiography (CR) of the hands, wrists, and feet. Furthermore, we characterize and quantify bone erosions in the two MTP joints by HR-pQCT. METHODS: This single-center cross-sectional study included patients with established RA (disease duration ≥5 years). Blinded to patient data, the number and volume of erosions in the 4th and 5th MTP joints were measured by HR-pQCT, whereas the erosive scores by CR of 44 joints in the hands, wrists, and feet were assessed according to the Sharp/van der Heijde method. RESULTS: Among 42 participants, 30 patients were classified with erosive RA and 12 with non-erosive RA by CR. HR-pQCT of two MTP joints could classify more patients with erosive RA compared with CR of 44 joints (p = .03). The optimal cut-off value for the number and volume of erosions per patient in the 4th and 5th MTP joints by HR-pQCT was 7.5 erosions and 11.7 mm3 , respectively, for detecting erosive disease by CR. Erosions in the two MTP joints by HR-pQCT were found most frequently and were largest at the lateral quadrant of the 5th metatarsal head. CONCLUSION: The superiority of HR-pQCT of the 4th and 5th MTP joints compared with CR of 44 joints for classifying erosive RA provides a basis for larger studies evaluating if HR-pQCT could be used for diagnosing erosive RA in the future.

RESUMO

Hallux valgus surgery and open reduction of the lesser metatarsophalangeal joints with metatarsal shortening osteotomy help treat severe hallux valgus concomitant with the lesser metatarsophalangeal joint dislocation; however, pre- and postoperative plantar pressure distribution and its effect on the foot remain unclear. The pre- and postoperative groups comprised 16 patients with moderate-to-severe symptomatic hallux valgus with lesser metatarsophalangeal joint dislocation. All feet underwent open reduction and collateral ligament reconstruction of the second metatarsophalangeal joint and proximal metatarsal shortening osteotomy under the second metatarsal with proximal osteotomy of the first metatarsal. Twenty healthy participants (20 feet) were included in the control group. The plantar pressure distribution was determined by measuring the peak pressure, maximum force, contact area, and force-time integral for 12 regions. Under the second toe, all measurements in the preoperative group were significantly lower than those of the control group. The peak pressure, maximum force, and contact area of the postoperative group were significantly greater than those of the preoperative group. However, no differences were observed between the postoperative and control groups. Under the second metatarsal head, the peak pressure of the preoperative group was significantly higher than that of the control group. The peak pressure of the postoperative group was significantly lower than that of the preoperative group and showed no differences from the control group. Open reduction and collateral ligament reconstruction of the lesser metatarsophalangeal joints and proximal metatarsal shortening osteotomy with proximal osteotomy of the first metatarsal in hallux valgus with lesser metatarsophalangeal joints dislocation cases may improve operative outcomes, including favorable foot function.

RESUMO

"Cup-shaped power reamers" and "flat cuts" (FC) are common joint preparation techniques in first metatarsophalangeal (MTP) joint arthrodesis. However, the third option of an "in situ" (IS) technique has rarely been studied. This study aims to compare the clinical, radiographic, and patient-reported outcomes (PROMs) of the IS technique for various MTP pathologies with other MTP joint preparation techniques. A single-center retrospective review was performed for patients who underwent primary MTP joint arthrodesis between 2015 and 2019. In total, 388 cases were included in the study. We found higher nonunion rates in the IS group (11.1% vs 4.6%, p = .016). However, the revision rates were similar between the groups (7.1% vs 6.5%, p = .809). Multivariate analysis revealed that diabetes mellitus was associated with significantly higher overall complication rates (p < .001). The FC technique was associated with transfer metatarsalgia (p = .015) and a more first ray shortening (p < .001). Visual analog scale, PROMIS-10 physical, and PROMIS-CAT physical scores significantly improved in IS and FC groups (p < .001, p = .002, p = .001, respectively). The improvement was comparable between the joint preparation techniques (p = .806). In conclusion, the IS joint preparation technique is simple and effective for first MTP joint arthrodesis. In our series, the IS technique had a higher radiographic nonunion rate that did not correlate with a higher revision rate, and otherwise similar complication profile to the FC technique while providing similar PROMs. The IS technique resulted in significantly less first ray shortening when compared to the FC technique.

RESUMO

First metatarsal phalangeal (MTP) joint arthrodesis has been employed for decades for pain related to arthritis and other associated abnormalities. Despite the commonality of the procedure there continues to be questions regarding functional expectations following the procedure especially when employed for correction of hallux valgus deformity. We surveyed 60 patients who had a tri plane MTP joint arthrodesis at mean 28.4 months (median 27.8) regarding their activities of daily living and sports activity through a direct conversation. Secondary endpoints assessed were return to activity, deformity correction and arthrodesis healing rate based on chart review and weightbearing radiographs. The primary outcomes showed robust return to all activities of daily living with 96.7% able to walk without restrictions and or pain, 98.3% were able to walk at a normal pace and 95% responded that loss of motion of their big toe did not affect their daily function. Regarding return to sports all patients that participated in sports before surgery resumed participation after with a trend toward increased sports activity. Early return to walking in a fracture boot was noted in this cohort at mean 4.1 days, return to athletic shoe at mean 6.3 weeks and full unrestricted activity at mean 13.3 weeks with no non-unions identified on radiographic or clinical exam. Deformity correction of the typical components of hallux valgus deformity was similar to previously published studies. This data set supports the hypothesis that patients undergoing first MTP joint arthrodesis can expect rapid and full return to activities of daily living and sports with a low complication rate.
