RESUMO
First metatarsalphalangeal (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 triplane 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 97% able to walk without restrictions and or pain, 98% 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.

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.

Ankle fractures are a common traumatic lower extremity injury and are generally classified and characterized by the rotational mechanism of injury. At each malleolus (i.e., posterior, medial, and lateral) a fracture can occur or a ligamentous injury may be sustained. The purpose of this retrospective study was to determine if bone mineral density is a contributing factor on the number of fractured malleoli versus soft tissue injury in adult ankle fractures. Data was obtained from a registry of ankle fractures that were operatively treated by the foot and ankle team throughout our institutional facilities, from July 2017 to August 2019, and in which a preoperative computerized tomography scan was performed. Regional bone mineral density (BMD) was measured by calculating the average Hounsfield Unit (HU) on axial computerized tomography images of the distal fibula and tibia. The average HU was then compared to the number of fractured malleoli. One hundred eight patients met the study criteria. We identified statistically significant relationships between decreased BMD with increasing age (p < .01) and the male gender (p < .01). After adjusting for the covariates age and gender, no statistically significant relationship was identified between BMD and the number of malleoli involved in a given ankle fracture (p = .11). These findings suggest that while more investigation is required for ankle fracture patterns and BMD evaluation, increased age and biologic female gender is significantly related to decreased BMD as identified via HU.

Vertical fixation through stemmed components has been a successful strategy in total ankle arthroplasty. Research in hip replacement surgery has demonstrated increased rates of stress shielding, aseptic loosening, thigh pain, and cystic formation around stemmed femoral implants extensively coated with porous surfaces. While some ankle prostheses have integrated porous coating technology with stemmed tibial implants, there is little to no research investigating the potential negative effects of bone bonding to the tibial stems and possible impact on tibial cyst formation. We performed a retrospective cohort study comparing the incidence of periprosthetic tibial cyst formation in smooth versus fully porous-coated stemmed tibial implants after undergoing total ankle implant arthroplasty. Radiographs were compared for postoperative rates of tibial cyst formation and bone bonding to the tibial stems. Relative risk for reoperation between the smooth and porous-coated implants was investigated. The smooth-stem group showed no incidence of tibial cyst formation nor signs of significant bone bonding to the tibial stems; however, the follow-up matched porous-coated group showed a rate of 63% of cystic formation with associated evidence of bone bonding on final radiographic follow-up (p < .01). Relative risk for reoperation was 0.74. Despite a higher incidence of tibial cyst formation in the stemmed ankle arthroplasty groups with porous coating, reoperation rates were similar. We theorize that the proximal bonding to the porous stem surface could impact the distal stems and result in the observed increase in cyst formation.

Accuracy and reproducibility when performing total ankle implant arthroplasty (TAA) are essential for longevity of the implant, maintaining relative stability of the joint, and theoretically reducing the formation of adjacent joint arthritis in the subtalar and knee joints. Studies have helped to illustrate the accuracy of implantation when using patient-specific instrumentation in both knee and ankle implant arthroplasty. Despite the findings of these studies, few have gone on to evaluate the effects of ancillary procedures on TAA; particularly their effects on postoperative implant congruity when performed simultaneously with joint replacement surgery. In this study, preoperative plans on implant alignment based on patient-specific computed tomography images were compared with the alignment observed on immediate postoperative radiographs. Additionally, postoperative joint congruity was measured, and operative reports were assessed to determine if concomitant procedures performed with total ankle replacement had a significant effect on overall alignment. In our population, 46/47 implants were within 1.5° of their anticipated placement in the coronal plane, and 100% were within 2° of anticipated placement in the sagittal plane. Using a spearman's rank-order correlation, our data failed to show any significant relationship between conducting additional procedures in conjunction with TAA (rho = 0.178; p value = .232) and postoperative congruency of the implant. These findings help support the accuracy of ankle implantation using patient-specific instrumentation, while also supporting the appropriate use of indicated procedures in conjunction with total ankle replacement to help obtain a congruent joint postoperatively.

Recent literature suggests the majority of osteochondral lesions occur in the ankle joint. Previous studies have suggested that varying incidences of talar osteochondral lesions (OCLT) are associated with ankle fractures. The primary aim of our study was to investigate the incidence of osteochondral lesions associated with acute ankle fractures as observed on computed tomographic (CT) imaging. We also compared the rates of talar osteochondral lesions in patients who had ankle fractures with dislocation and closed manual reduction (CMR) prior to open reduction with internal fixation, to those who did not suffer from ankle joint dislocation. Additionally, a correlation between the location of talar dome lesions with type of ankle fracture as classified by Lauge-Hansen was investigated. Preoperative CT imaging was retrospectively reviewed in 108 patients with acute ankle fractures. A CT-modified version of Berndt Hardy's classification of osteochondral lesions, as previously described by Loomer et al, was used for diagnosis of lesions in our study. The incidence of lesions was calculated across all subjects, and retrospective comparison was performed in those who did and did not undergo closed manual reduction. Supplementary data on location of lesion and its association with ankle fracture type was also recorded. We found an overall incidence of 50.9% OCLT in patients with acute ankle fractures. This number did not significantly differ from those who underwent closed manual reduction (49%). Although a majority of lesions did occur posteriorly, we saw no statistically significant information was seen between either type of fractures or OCLT locations. Careful consideration and thorough evaluation of preoperative CT imaging should be assessed by the performing surgeon, as this could guide both diagnostic and therapeutic treatments for patients with possible osteochondral lesions of the talus undergoing surgical repair of a fractured ankle.

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.

A malaligned ankle arthrodesis is a painful and complicated pathology. Deformities may be present in the frontal, sagittal, or transverse plane or a combination of planes. Thorough preoperative evaluation of the deformity and the patient as a whole is crucial to successful revision. Surgical site for revision should be based on center of rotation of angulation, when possible. Revision commonly is performed through opening wedge osteotomy. Closing wedge and focal dome osteotomies, however, are excellent options. Revision also may be performed through external fixation or total ankle replacement. Although the literature is not rich with data, the options discussed provide favorable results.
