Tibialis anterior and extensor hallucis longus tendon ruptures complicating a closed tibial fracture: A case report.

INTRODUCTION AND IMPORTANCE: Acute rupture of the tibialis anterior tendon and other tendons is an extremely rare injury. It is usually associated with minor trauma in older patients with medical comorbidity. Surgeons must be alert for rupture of these tendons which can complicate a closed tibial fracture. CASE PRESENTATION: A 19-year-old man was transferred to the emergency department with a segmental fracture at the lower third of his tibia. The patient could not actively dorsiflex his right ankle and first toe but was able to dorsiflex other toes actively. The tibialis anterior and extensor hallucis longus tendon were discovered torn at the same point, supposedly by a bone spike. The fracture was reduced and fixed and the tendons were repaired. CLINICAL DISCUSSION: A traumatic rupture of the tibialis anterior and extensor hallucis longus tendons occurs rarely in conjunction with or as a consequence of a bony fracture in closed trauma, with only a few cases documented in the literature. They typically occur as a result of direct blunt or penetrating injury. In three papers, the tibial fracture caused a direct rupture in the tendon. We believe that the tendons rubbing against the fractured edges of the segmental bone of the tibia led to the tendons tearing gradually. CONCLUSION: Further investigation is needed for an evaluation of ankle and first toe dorsiflexion to check for a palpable gap in the soft tissues of a lower third tibial fracture. The tibialis anterior and other tendons can be located between the segment of the tibial fracture and ruptured.

Single procedure tibialis anterior tendon shortening in combination with Achilles tendon lengthening in unilateral cerebral palsy improves swing phase dorsiflexion in gait.

Purpose: Tibialis anterior tendon shortening combined with tendon Achilles lengthening showed satisfactory short- and long-term outcomes for pes equinus treatment. This retrospective study aimed to evaluate the effectiveness of a single tibialis anterior tendon shortening-tendon Achilles lengthening procedure for treating pes equinus, in a homogeneous unilateral cerebral palsy patient group. Methods: Gait analysis was conducted on 22 unilateral cerebral palsy patients (mean age at surgery = 13.3 years, standard deviation = 3 years) before and within 2.5 years (standard deviation = 0.61 years) after the tibialis anterior tendon shortening-tendon Achilles lengthening procedure. Primary outcome measures included foot drop occurrence in swing, foot dorsiflexion and the first ankle rocker presence compared to healthy reference data. Movement analysis profile and gait profile score were also calculated for the entire gait cycle. The clinical exam and the A2 peak ankle power were analyzed. Statistical analysis used the paired Wilcoxon's sign rank test (p < 0.05). Results: Post-operatively, significant improvements were observed in ankle dorsiflexion during swing (p = 0.0006) and reduced foot drop in swing (p = 0.0107). The occurrence of a first ankle rocker did not significantly change (p = 0.1489). Significant improvements in gait profile score and movement analysis profile for all joints and planes indicate overall gait quality improvement. The foot progression changed significantly (p = 0.0285), with a greater external orientation. Nineteen out of 22 patients were able to quit wearing their ankle foot orthoses. Conclusion: Tibialis anterior tendon shortening and tendon Achilles lengthening combination yielded positive outcomes, showing increased foot dorsiflexion, first ankle rocker presence, and overall improved gait quality. These findings support the effectiveness of this surgical approach for treating pes equinus in children with unilateral spastic cerebral palsy.

Avulsion Fracture of the Tibialis Anterior Tendon Associated with First Metatarsal Base Fracture: A Case Report and Literature Review.

We present a unique case of a 59-year-old shipyard worker who sustained an avulsion fracture of the tibialis anterior tendon, concurrently with a comminuted fracture at the base of the first metatarsal. This is the first reported case highlighting this concomitant presentation, which underlines the possibility of avulsion fractures accompanying comminuted fractures. Importantly, such avulsion fractures could lead to skin tenting and potential necrosis, necessitating early identification and prompt intervention. The patient underwent successful surgical intervention and displayed good functional restoration 15 months postoperatively.

Outcomes of Platelet-Rich Plasma Infiltration and Weightbearing Cast Immobilization in Distal Tibialis Anterior Tendinopathy: A Prospective Cohort Study.

BACKGROUND: Distal tibialis anterior tendinopathy (DTAT) is a chronic condition that may lead to functional impairment and secondary forefoot deformities when left untreated. Current clinical practice is mainly guided by case reports and small retrospective case series; little consensus exists on which treatment protocol is most effective. This study aims to assess a conservative treatment for DTAT consisting of PRP infiltration and walking cast immobilization. METHODS: This prospective study included 18 feet in 18 patients, recruited between September 2020 and September 2022 at a single institution. Ultrasonography was performed; leukocyte-poor PRP was infiltrated around the tibialis anterior tendon insertion. Walking cast immobilization was used for 3 weeks after infiltration, followed by eccentric exercises of the DTAT, and gastrocnemius-soleus muscle complex stretching. Clinical findings, visual analog scale (VAS), Foot Function Index (FFI), and American Orthopaedic Foot & Ankle Society (AOFAS) midfoot scores were recorded at inclusion, and 6 and 12 weeks after PRP infiltration. Minimal clinically important difference (MCID) limits were researched to assess clinical relevance of statistical outcomes. Means were determined for age, sex, and body mass index (BMI). One-way repeated measures ANOVA was performed over time for FFI, AOFAS, and VAS scores. RESULTS: Mean age was 65 years with a mean BMI of 25. Tendon thickening and hypoechogenicity were the most commonly reported ultrasonographic findings. Significant improvement from baseline VAS (VASrest: 4.71 ± 2.7, VASactivity: 5.66 ± 2.5) to 12 weeks follow-up (VASrest: 2.14 ± 2.7, VASactivity: 3.34 ± 2.5) was found. Both AOFAS and FFITotal improved significantly from baseline (AOFAS: 66.9 ± 3.3, FFITotal: 32.9 ± 3.3) to 6-week follow-up (AOFAS6w: 79.4 ± 3.3, P = .019; FFITotal: 19.4 ± 3.3, P = .011). No statistically significant further improvement was found at 12 weeks compared to 6 weeks' follow-up. Two (11%) patients chose operative treatment because of persisting symptoms. CONCLUSION: We found that PRP infiltration with walking cast immobilization as a first-line treatment was associated with general early symptom improvement. LEVEL OF EVIDENCE: Level IV, case series.

A Rare Presentation of Bifid Tibialis Anterior Tendon in a Case of Idiopathic Congenital Talipes Equinovarus.

Introduction: Idiopathic congenital talipes equinovarus (CTEV) is one of the most extensively researched topics for decades. It has been associated with various musculoskeletal anomalies which maybe bony, vascular or involving the ligaments and muscles which may have a direct or indirect impact on its pathoanatomy. This report describes an unusual presentation of a bifid tibialis anterior tendon (TAT) in a case of CTEV. This is the first report of this kind in the literature to the best of our knowledge. Case Report: A 4-year-old female presented with bilateral relapsed CTEV with dynamic supination previously treated with standard Ponseti protocol. The patient was treated with TAT transfer on the left side with a rare presentation of a bifid TAT where both the slips of the tendon were transferred to dorsum of the foot onto the lateral cuneiform. Conclusion: When treating a patient of CTEV surgically, it is important to consider the possibility of a bifid TAT which is a rare musculoskeletal association. It is recommended to carefully dissect TAT to prevent under correction of the deformity in case either one of the tendon slips remains attached to its original site.

Anatomical study of type classification and surface area of attachment sites for tibialis anterior tendon.

BACKGROUND: The purpose of this study was to clarify the attachment types of the tibialis anterior tendon (TAT) in Japanese fixed cadavers and to determine the attachment site area in three dimensions. METHODS: We examined 100 feet from 50 Japanese cadavers. The TAT was classified according to differences in the number of fiber bundles as: Type I, with one fiber bundle; Type II, with two fiber bundles; and Type III, with three fiber bundles. The attachment site area of the TAT was measured using a three-dimensional scanner. RESULTS: Cases were Type II in 95% and Type III in 5%, with no cases of Type I identified. In Type II, mean attachment site areas were 85.2 ± 18.2 mm2 for the medial cuneiform bone (MCB) and 72.4 ± 19.0 mm2 for the first metatarsal bone (1 MB), showing a significantly larger area for MCB than for 1 MB. CONCLUSIONS: These findings suggest the possibility of ethnic differences in TAT attachment types and suggest that TAT attachments in Japanese individuals are highly likely to be Type II, with rare cases of Type III. Accurate measurement of attachment site areas is possible with appropriate three-dimensional measurements.

Early Resection of the Tibialis Anterior Tendon for Tendon Exposure After Total Ankle Arthroplasty to Prevent Deep Infection: A Report of Three Cases in Patients With Rheumatoid Arthritis.

Exposure of the tibialis anterior (TA) tendon with wound dehiscence after total ankle arthroplasty (TAA) with the anterior approach is a problematic complication, especially in rheumatoid arthritis (RA) patients. Once the TA tendon is exposed, the duration of wound healing is prolonged, and it could be a risk factor for deep infection. Thus, early resection of the TA tendon was evaluated for tendon exposure with wound dehiscence after TAA in RA patients. In this case report, three rheumatoid ankles that showed wound dehiscence with exposure of the TA tendon after TAA with the anterior approach are presented. Early resection of the TA tendon and debridement under local anesthesia were performed within two days after wound dehiscence. In all cases, wound healing was completed within two weeks after the treatment. Drop foot was not seen in any patients, and there was no difference between the pre and postoperative (1 year after TAA) range of dorsiflexion. Muscle strength for ankle dorsiflexion was also maintained. In conclusion, early resection of the TA tendon appears to be a useful option for undesirable tendon exposure with wound dehiscence to prevent deep infection and prolonged wound healing after total ankle arthroplasty in RA patients.

A three-dimensional analysis of the tibialis anterior tendon: emphasizing tendon insertion patterns for effective repair and understanding hallux valgus development.

PURPOSE: The present study aimed to evaluate the insertion site of the tibialis anterior tendon three-dimensionally. METHODS: Seventy lower limbs were dissected. The tibialis anterior tendon was dissected to verify the insertion site to the medial cuneiform and the base of the first metatarsal bone. The three-dimensional (3D) territory of the tibialis anterior tendon insertion on the medial cuneiform and the first metatarsal bones was measured on a reconstructed 3D model. RESULTS: The insertion pattern of the tibialis anterior tendon was classified into three types, the most common being Type I: a single tibialis anterior tendon dividing into two equal-sized bands to the medial cuneiform and base of the first metatarsal bone (57.1%, 40/70 of cases). The 3D territory of the tibialis anterior tendon was larger in the plantar aspect than in the medial side of both the medial cuneiform and the base of the first metatarsal bone. The width of the tendon inserted into the medial cuneiform was wider than that inserted into the first metatarsal bone. CONCLUSION: The tibialis anterior tendon was more commonly attached to the plantar part than the medial part in both the medial cuneiform and the base of the first metatarsal bone. This anatomical information will help surgeons perform anatomical reconstruction of the tibialis anterior tendon, reduce further tendon damage in the first metatarsocuneiform joint area and also provide valuable knowledge to improve understanding of hallux valgus pathogenesis.

Tibialis anterior tendon transfer using suture anchor provides excellent alternative treatment for relapse clubfoot: A case report.

INTRODUCTION: Relapsed clubfoot is defined as the recurrence of any component of deformity after a complete correction. While the Ponseti method has been known to have excellent outcomes, several relapse cases have been reported. Thus, further surgical intervention is needed to achieve a good and reliable long-term outcome. PRESENTATION OF THE CASE: We report a presentation of a 5-year-old boy who came to the clinic with a relapsed bilateral clubfoot after serial Ponseti casting. Plantar fascia release, Achilles tendon lengthening, and tibialis anterior tendon transfer (TATT) were performed respectively followed by an above-knee cast. The patient gained acceptable walking balance and ability to perform high impact sports at one year follow-up. CLINICAL DISCUSSION: There are several factors contributing to the relapse clubfoot including adherence to post op foot abduction brace (FAB) protocol, muscle imbalance or inadequate correction of initial deformities. The current case report described a relapse clubfoot following serial Ponseti casting caused by non-compliance of the use of foot abduction brace. Further surgical interventions must be performed in the presence of relapse case of clubfoot. CONCLUSION: Relapse clubfoot is the presence of any recurring deformity following correction. Surgical intervention, especially TATT procedure provides a favorable outcome in treating patients with relapse clubfoot.

Tibialis Anterior Tendon Rupture Surgical Treatments and Outcomes: A Systematic Review and Meta-Analysis.

Tibialis anterior tendon ruptures are a rare condition with an often-delayed diagnosis due to transient pain and compensation of remaining anterior compartment tendons. Previous systematic reviews have limited their recommendations to surgical treatment over nonoperative cares given the relatively small sample size in the literature. This current systematic review and meta-analysis was performed to compare the outcomes amongst the various surgical techniques and define factors that may affect long term patients results. Twenty-six references (217 cases) were identified. Use of extensor tendon autograft (odds ratio [OR] 5.55; I2=46%), autograft repair through semitendinosus/gracilis/ plantaris/ Achilles tendon/ peroneus longus ([OR] 4.14; I2=71%), or direct repair ([OR] 3.59; I2=57%), provided the best postoperative outcomes, whereas allograft repair ([OR] .52; I2=77%),and ipsilateral split/ turn-down tibialis anterior tendon ([OR] .69; I2=71%), were associated with poorer outcomes. Ruptures fixed in the acute phase ([OR] 8.3; I2=26%), were associated with statistically significant better outcomes when compared to these ruptures fixed in the chronic phase ([OR] .52; I2=77%). Results of this systematic review and meta-analysis suggests that ruptures should be surgically repaired in the acute phase whenever possible and comparable outcomes can be achieved through extensor tendon autograft repair, autograft repair, and direct repair.

The Effects of Tibialis Anterior Tenotomy on Wound Complications and Functional Outcomes After Anterior Fusion Plating for Severe Ankle Arthritis.

Nonunion is known to be a relatively common complication following ankle arthrodesis. Various fixation techniques have been introduced to enhance the stability and to improve fusion rate. With the use of anterior plate supplementation, postoperative wound problems have been frequently reported despite better fusion rate. This study was performed to determine the effects of tibialis anterior (TA) tenotomy on wound complications and functional outcomes after anterior fusion plating for severe ankle arthritis. Forty-six patients who underwent ankle arthrodesis using anterior fusion plate were followed for more than 2 years. TA tenotomy was performed prior to wound closure in all patients. As a control group, 38 patients who underwent arthrodesis without TA tenotomy were analyzed. Functional outcomes were evaluated with Ankle Osteoarthritis Scale and Foot and Ankle Ability Measure. Wound complication rate, time to fusion, fusion rate, time to pain relief were evaluated. Mean Ankle Osteoarthritis Scale and Foot and Ankle Ability Measure scores significantly improved to 32.6 and 69.4 points at final follow-up, respectively. As compared to control group (33.8 and 67.7 points), there were no significant differences in functional outcomes. As postoperative wound complications, there were 1 case of wound dehiscence and 1 case of superficial wound infection. TA tenotomy group showed a significantly lower wound complication rate (4.3%) than control group (23.7%) (p < .001). While there were no significant differences in fusion rate, time to fusion, and time to pain relief between both groups, control group needed higher rate of implant removal. Ankle arthrodesis using anterior fusion plate in conjunction with TA tenotomy appears to be an effective surgical option for end-stage ankle arthritis, with excellent fusion rate and less wound complication rate. Although there were no specific functional deficits related to absence of TA tendon, further studies are needed to determine long-term effects of TA tenotomy in patients with a fused ankle.

[Minimally invasive tibialis anterior tendon transfer in shuttle technique for the treatment of clubfoot recurrence in adolescent patients]. / Minimalinvasiver Tibialis-anterior-Sehnentransfer in Shuttle-Technik zur Behandlung des Klumpfußrezidivs im Wachstumsalter.

OBJECTIVE: Tibialis anterior transfer in shuttle technique using the tunnelator is an atraumatic surgical technique without injuring the extensor retinaculum. The technique allows for postoperative treatment with pain-adapted full weight-bearing for 6 weeks in a lower leg cast which is simplified compared to the current literature. INDICATIONS: Passive, correctable clubfoot recurrences in the event of muscular imbalance (overbalanced anterior tibial muscle). CONTRAINDICATIONS: Structural movement restrictions of the foot, muscular insufficiency of the anterior tibial muscle, infection or cancerous lesions in the surgical site. SURGICAL TECHNIQUE: Loosen the tibialis anterior muscle at the base of the first metatarsal. Guide the tendon proximally out of the extensor retinaculum, then shuttle the tendon below the retinaculum with the help of the "tunnelator" and transosseous fixation at the lateral cuneiform. POSTOPERATIVE MANAGEMENT: Pain-adapted full weight-bearing in a lower leg walking cast for 6 weeks postoperatively. RESULTS: In the course of a retrospective study, the above-mentioned surgical procedure was carried out in 20 patients (total n = 26 surgeries) between 2013 and 2019. After a follow-up of 12 months, complete correction of the clubfoot relapse was found in 88.5% of cases. There were no general or specific surgical complications.

Kinematic differences in the presentation of recurrent congenital talipes equinovarus (clubfoot).

BACKGROUND: The tibialis anterior tendon transfer (TATT) is the suggested surgical intervention in the Ponseti method for treatment of dynamic recurrent congenital talipes equinovarus (clubfoot) presenting as hindfoot varus and forefoot supination during the swing phase of gait. The indication for surgery, however, is typically based on visual assessment, which does not sufficiently examine the variability of foot motion in this cohort. RESEARCH QUESTION: The aim of this research was to determine whether subgroups, based on foot model kinematics, existed within a clubfoot cohort being considered for TATT surgery. METHODS: Sixteen children with recurrent clubfoot that had been previously treated with the Ponseti method and were being considered for tendon transfer surgery were prospectively recruited for this study and were required to attend a pre-surgery data collection session at the Queensland Children's Motion Analysis Service (QCMAS). Data collected included standard Plug-in-Gait (PiG) kinematics and kinetics, Oxford Foot Model (OFM) foot kinematics, and regional plantar loads based on anatomical masking using the integrated kinematic-pressure method. RESULTS: Results of this study identified two clear subgroups within the cohort. One group presented with increased hindfoot inversion across 91 % of the gait cycle. The second group presented with increased hindfoot adduction across 100 % of the gait cycle. Hindfoot adduction was statistically significantly different between the two groups. SIGNIFICANCE: The identification of these two groups propose a need for further classification of deformity within this cohort and query the appropriateness of this surgical intervention for both presentations.

Reconstruction of chronic tibialis anterior tendon ruptures using a free anterior half of a peroneus longus tendon autograft: A technical note.

Purpose: Chronic rupture of the tibialis anterior (TA) tendon is rare. Several reconstruction techniques have been introduced. However, to the best of our knowledge, the use of a free anterior half of a peroneus longus tendon (AHPLT) autograft has not been reported for reconstruction of TA tendon rupture. This study aimed to describe the surgical technique and present the clinical outcomes of reconstruction of the chronic TA tendon ruptures using an AHPLT autograft. Methods: Between September 2013 and April 2019, five patients with chronic TA tendon rupture were surgically treated by reconstruction using an AHPLT autograft. The AHPLT could be easily harvested percutaneously with a tendon stripper from the ipsilateral lower leg around the reconstruction site. The study included four men and one woman, with a mean age of 43.8 (range: 23-65) years. Results: At a mean follow-up period of 42.8 (range; 12-70) months, the mean Foot Function Index value significantly improved from 53.6 ± 19.8 preoperatively to 25.8 ± 20.8 postoperatively (p = .04). None of the patients had morbidities (such as nerve injury, delayed tendon ruptures, or tenosynovitis) around the AHPLT donor site. Three patients were very satisfied, two patients were satisfied, and one patient was fair with the results. Conclusions: Reconstruction of chronic TA tendon ruptures using a free AHPLT autograft could be successfully performed with satisfactory clinical outcomes and minimal donor site morbidities. Future studies with a larger population size and a comparative group are warranted to confirm these findings.

Outcomes of Tibialis Anterior Tendon Reconstruction with Autograft or Allograft.

BACKGROUND: In cases of tibialis anterior tendon (TAT) ruptures associated with significant tendon defect, an interposition graft is often needed for reconstruction. Both auto- and allograft reconstructions have been described in the literature. Our hypothesis was that both graft types would have a good integrity and provide comparable outcomes. METHODS: Patients who underwent TAT reconstruction using either an auto- or allograft were identified. Patient-reported outcomes (PROs) were collected using the 12-Item Short Form Health Survey (SF-12) questionnaire, the American Orthopaedic Foot & Ankle Society (AOFAS) hindfoot score, the Foot Function Index (FFI), and the Karlsson-Peterson score. Functional outcome was assessed by isokinetic strength measurement. Outcomes were further assessed with magnetic resonance imaging (MRI) evaluation of graft integrity. All measurements were also performed for the contralateral foot. RESULTS: Twenty-one patients with an average follow-up of 82 months (20-262 months), comprising 12 allograft and 9 autograft TAT reconstructions, were recruited. There were no significant differences in patient-reported outcomes between allograft reconstructions and autografts: SF-12 (30.7 vs 31.1, P = .77); AOFAS (83 vs 91.2, P = .19); FFI (20.7% vs 9.5%, P = .22); and Karlsson-Peterson (78.9 vs 87.1, P = .23). All grafts (100%) were intact on MRI with a well-preserved integrity and no signs of new rupture. There were no major differences in range of motion and functional outcomes as measured by strength testing between the operative and nonoperative side. CONCLUSION: Reconstructions of TAT achieved good PROs, as well as functional and imaging results with a preserved graft integrity in all cases. There were no substantial differences between allograft and autograft reconstructions. LEVEL OF EVIDENCE: Level IV, retrospective case series.

Surgical outcome of a post-traumatic dystonic foot: Case report and literature review.

Post-traumatic dystonia is an underrecognized condition that can present with bizarre symptoms after trauma, usually out of proportion to the trigger event. We describe the case of a 31-year-old man with a severe lower extremity deformity, gradually developed after minor trauma. An interdisciplinary treatment was tried without any improvement and surgery was performed as a rescue approach. Tibialis anterior tendon transfer and hindfoot triple arthrodesis were carried out, successfully achieving a plantigrade foot and a functional gait. Despite the scarce literature available about functional results of surgery in dystonic feet, we present a step-by-step comprehensive approach to this disorder. LEVEL OF CLINICAL EVIDENCE: 4.

Anatomical variations of the tibialis anterior tendon.

INTRODUCTION: The tibialis anterior muscle originates from the medial part of the anterior compartment, from the upper two-thirds of the lateral surface of the tibia and the adjacent part of the interosseous membrane, and typically inserts to the medial cuneiform and first metatarsal bone. The goal of the study was to examine the insertion of the tibialis anterior tendon and create a classification in human fetuses. MATERIALS AND METHODS: Fifty spontaneously-aborted human fetuses (26 male, 24 female, 100 lower limbs), aged 18-38 weeks of gestation at death were examined. RESULTS: The classification comprised five types of tibialis anterior tendon insertion. The most common was Type V (60%), which was characterized by a single tendon inserting onto the medial cuneiform bone. The second most frequent was Type I (19%), which was characterized by a tendon which split into two equal-sized parts that insert to the medial cuneiform bone and the base of the first metatarsal. The third was Type II (12%), which was characterized by a tendon splitting into two different-sized parts that inserted onto the medial cuneiform bone (larger component) and the base of the first metatarsal (smaller component). The fourth type was Type III (5%), which was also characterized by a tendon splitting into two different-sized parts that inserted onto the medial cuneiform bone (smaller component) and the base of the first metatarsal (larger component). Finally, Type VI (4%), the least frequent type, was characterized by a tendon splitting into three different-sized parts, inserting onto the medial cuneiform bone (the smallest component) and the base of the first metatarsal (the middle and larger component). CONCLUSION: The tibialis anterior muscle is characterized by high variability in the approach of its tendon to the foot, at least in fetuses. This is classified in the present study for the first time.

A report of three cases which required tibialis anterior tendon resection to recover delayed wound healing after total ankle arthroplasty in patients with rheumatoid arthritis.

Delayed wound healing is one of the severe complications after total ankle arthroplasty (TAA). In particular, once tibialis anterior (TA) tendon is exposed from tendon sheath of extensor retinaculum, wound healing will be critically intractable. We report three cases (mean age: 75.3 years old) of delayed wound healing after TAA cured by resection of TA tendon in patients with rheumatoid arthritis (RA). All three cases underwent TAA through an anterior approach, with careful suture of extensor retinaculum in wound closure. Ankle joint was fixed with splint and avoid weight bearing for three weeks after surgery. Delayed wound healing with TA tendon exposure was observed, and initially treated by debridement, basic fibroblast growth factor spray, and negative pressure wound therapy, which all failed to obtain wound healing. Finally, complete resection of TA tendon led to rapid wound healing. In all cases, ankle dorsal flexion was compensated by other extensors, with maintained range of motion and muscle strength (manual muscle testing 3 to 4) compared to pre-operation at 1 year after TAA operation. Resection of TA tendon may be considered as one of the salvage treatment options of severe delayed wound healing in TAA with anterior approach, especially in elderly patients.

Removal of Painful Os Paracuneiforme: A Case Report.

Os paracuneiforme (OPC) is an extremely rare accessory bone located either medial to the medial cuneiform or to the naviculocuneiform joint. Although OPC often appears on the list of accessory ossicles, there are few reported cases regarding this bone. OPC can cause symptoms that require surgical intervention, but only 2 surgically treated cases have been published in the literature in English. Here, we report the case of a patient with painful OPC who was surgically treated. The patient showed no restriction in his daily living and recreational activities 6 months postoperatively. This is the first report showing not only preoperative and postoperative radiographs, but also preoperative CT images, photographs of intraoperative findings, and the resected ossicle. Level of Evidence: Level V.

Management of tibialis anterior tendon rupture: Recommendations based on the literature review.

Tibialis anterior tendon (TAT) rupture is a rare injury that commonly diagnosed late due to mild clinical signs and symptoms. Management of TAT rupture is a topic without a clear consensus in the literature. This current concept review tries to shed some light on the data and treatment. Our extensive literature review identified 81 case reports and case series from 1905 to 2018. Several reported management techniques with their advantages and disadvantages were analyzed and our treatment recommendations are given based on current available evidences. LEVELS OF EVIDENCE: IV.
