Flexor hallucis longus muscle can adhere to the distal tibia after tibial fracture. The patient may complain of deep posteromedial ankle pain, checkrein deformity of the hallux, hallux flexus or development of hallux rigidus. Surgical treatment of release of the FHL muscle or lengthening of the FHL tendon has been proposed. We described an endoscopic approach of release of the FHL muscle from the distal tibia with the advantage of minimal soft tissue dissection.

Flexor Digitorum

The flexor digitorum accessory longus (FDAL) muscle is one of the most commonly encountered anomalous muscles in the foot and ankle. Literature has documented the prevalence of the FDAL anywhere from 4% to 12%, based on cadaveric limb dissection. The variability of the origin, insertion, size, and location of the FDAL muscle can cause a wide array of foot and ankle pathologies, most notably, tarsal tunnel syndrome and flexor hallucis longus syndrome. Accessory musculature should be included in the list of differential diagnoses for foot and ankle pain until proven otherwise. This report presents a patient who exhibited pain localized to the medial malleolar region and was initially diagnosed with likely tarsal tunnel syndrome. On magnetic resonance imaging, a FDAL muscle was identified and shown to be impinging on the posterior medial anatomic structures. The patient underwent excision of the FDAL and is symptom free to date. The discussion of this case report can prompt foot and ankle surgeons to be more aware of this infrequent finding as well as treatment options. Level of Evidence: Therapeutic, Level IV

Ankle Ligament

Background: The purpose of this article is to document the normal arthroscopic appearance of the posterior ankle capsular and ligamentous structures, and variations in their anatomical relationships. Methods: 102 ankle arthroscopy videotapes were evaluated retrospectively for the configuration of the posterior capsuloligamentous structures. Based on these observations, the variations in the appearance and position of the posterior tibiofibular ligament (PTFL) and transverse (tibiofibular) ligament (TTFL) were documented. In addition, differences in the appearance of the flexor hallucis longus (FHL) were also noted. Results: All patients had evidence of both a PTFL and TTFL, which formed a labrum or meniscus-like addition to the posterior distal tibia. No patients demonstrated disruption of the PTFL; 3 had tears of the TTFL. We noted 4 distinct patterns of the PTFL and the TTFL. Thirty-four patients (33%) had a gap of ≥2 mm between the 2 ligamentous structures. Thirty-three (32.4%) had a gap <2 mm between the PTFL and TTFL. Twenty-six (25.5%) had a confluence of the 2 ligaments without a gap. Nine (9%) demonstrated a sizable gap between the 2 ligaments, and the TTFL appeared as a “cord-like” structure. Conclusion: To our knowledge, this is the first article to describe the variations in the arthroscopic normal posterior capsuloligamentous structures and FHL of the ankle.

Secondary Ossification Center

Background: Os trigonum (OST) is commonly located on the posterior aspect of the talus. It occurs as a result of secondary ossification center failing to fuse with the lateral tubercle of the posterior process of the talus; its incidence varies between 2 and 25%, and is more often bilateral. It occurs as an intra-articular Os, which is most often securely rooted to the lateral tubercle of the talus by a fibrocartilaginous synchondrosis. Aims and Objective: To determine the incidence, morphology, and distribution of Os Trigonum (OST). Materials and Methods: Retrospective 500 lateral foot radiographs view were studied to determine the incidence, morphology, and distribution of OST. Results: Incidence of OST in the present study was 6.6%, with predominantly round or ovoid in shape. OST was located on the posterolateral aspect of the talus. Conclusion: OST can be one of the causative factor responsible for Flexor hallucis longus tendonitis, OST syndrome, which occur in plantarflexion of the ankle, leading to compression of the OST between the distal tibia and the calcaneus. Hence, knowledge regarding the incidence, morphology, and distribution of OST is important for the radiologist, orthopedic surgeons to arrive at a correct diagnosis, which aids in the management of cases presenting with complaints of posterior ankle pain.

Sports Activity

Background: Realignment-surgery to unload ankle osteoarthritis (OA) has been proposed as treatment alternative for varus and valgus ankle OA. Sports activity after this procedure has not been analyzed. Realignment-surgery increases sports activity. Sports activity correlates with ankle pain, function, and alignment, but does not influence revision rate. Materials and Methods: Prospective case series of 35 consecutive patients with post-traumatic varus or valgus ankle OA limited to half tibiotalar joint surface were treated by OA unloading realignment-surgery. Distal tibia osteotomy was used in all cases; additional osteotomies, tendon, ligament procedures in 92% of cases. Main Outcome Measurements: Pain (visual-analogue-scale; VAS), ankle range-of-motion (ROM); function (American-Orthopaedic-Foot-and-Ankle-Society (AOFAS) ankle-score; Swiss-symptom-related-Ankle-Activity-Scale (SAAS); Sports-Frequency-Score (SFS), OA and tibiotalar-alignment-grade (Takakura-Score), and revision surgery. Mean followup was 5 years. Results: Mean values from preoperative to followup: VAS decreased ( p = 0.0001) 4 points; ankle ROM increased ( p = 0.001) 5 degrees; AOFAS-Score increased ( p = 0.0001) 46 points; SAAS increased ( p = 0.0001) 42 points; SFS increased ( p = 0.02) 0.5 grades; Takakura-score decreased ( p = 0.0001) 1.0 grades. Revision surgery was performed in 10 cases (29%). Three of these were revised to ankle arthroplasty. At follow-up, SAAS correlated with VAS, AOFAS score, Takakura score, and not with ROM or SFS. SFS did not correlate with other variables. Patients needing revision surgery had a higher ( p = 0.003) SFS than patients who needed no revision. Conclusion: Realignment-surgery increased sports activity of ankle OA patients. Improved ankle pain and function correlated with ability to perform activity without symptoms; however, sports frequency had no correlation to patients' symptoms but showed higher revision rate.

Abstract Purpose To investigate, if patients with complex proximal tibial fracture have realistic expectations on open reduction and internal fixation. Methods 114 patients (mean 49 years, SD ± 13) with closed AO-type B and C proximal tibial fracture were grouped (group B, respectively C). Prior to surgery expectations concerning knee function, pain, return to work/sports, and the risk for osteoarthritis was assessed with the Hospital for Special Surgery-Knee Surgery Expectations Survey (HFSS-KSE) and a non-validated ten-item survey. Results 92% of patients expected at least an almost natural knee postoperatively. All items regarding restoring knee function were ranked to be at least important in both groups. 65% in group B and 47% in group C expected at most occasional pain. 83% in group B and 67% in group C expected full return to work without any limitations. Patients with low physical work intensity expected significantly shorter incapacity to work in both groups (7.8, respectively 8.9 weeks). 71% in group B and 60% in group C expected to return to sports with at most small limitations. 33% in group B and 22% in group C assumed risk for osteoarthritis will be prevented by surgery. Conclusion Expectations on surgery for complex proximal tibial fracture are high regardless of fracture type. The prognosis of many health and lifestyle domains was overestimated. The risk for osteoarthritis was underestimated. This study should sensitize surgeons to discuss realistic expectations. This may help to improve patient comprehension what leads to sensible expectations, resulting in improved patients´ satisfaction. Level of evidence IV.

Stepwise Procedure

The aim of this study is to find basic quantitative geometric data that may contribute to the understanding of the etiology of hallux valgus. Embalmed specimens with existing hallux valgus (N = 39) were dissected; 28 variables were measured with a Vernier caliper gauge and toe goniometer. Correlations between pairs of independent variables were calculated. Linear dependency of the hallux angle, varus angle, and the width of the forefoot on a number of independent variables was analyzed by multiple linear regression. A least squares method and a stepwise procedure were used. The distance from the tendon of the flexor hallucis longus muscle to the head of the first metatarsal bone explains more than other variables the variation in hallux angle and width of the forefoot. A widened forefoot is significantly correlated with both hallux and varus angles. The interrelation of the predictor parameters illustrates the complicated hallux valgus phenomenon.

Background The purpose of this investigation was to compare rates of filled opioid prescriptions and prolonged opioid use in opioid naïve patients undergoing total shoulder arthroplasty (TSA) in inpatient versus outpatient settings. Methods A retrospective cohort study was conducted using a national insurance claims database. Inpatient and outpatient cohorts were created by identifying continuously enrolled, opioid naïve TSA patients. A greedy nearest-neighbor algorithm was used to match baseline demographic characteristics between cohorts with a 1:1 inpatient to outpatient ratio to compare the primary outcomes of filled opioid prescriptions and prolonged opioid use following surgery between cohorts. Results A total of 11,703 opioid naïve patients (mean age 72.5 ± 8.5 years, 54.5% female, 87.6% inpatient) were included for analysis. After propensity score matching (n = 1447 inpatients; n = 1447 outpatients), outpatient TSA patients were significantly more likely to fill an opioid prescription in the perioperative window compared to inpatients (82.9% versus 71.5%, p < 0.001). No significant differences in prolonged opioid use were detected (5.74% inpatient versus 6.77% outpatient; p = 0.25). Conclusions Outpatient TSA patients were more likely to fill opioid prescriptions compared to inpatient TSA patients. The quantity of opioids prescribed and rates of prolonged opioid use were similar between the cohorts. Level of evidence Therapeutic Level III.

Category: Other Introduction/Purpose: Hallux rigidus is one of the most common pathologies afflicting the foot. Various joint salvage techniques have been described with a multitude of different implants. Recently, a synthetic cartilage implant composed of polyvinyl alcohol (PVA) received FDA premarket approval for treatment of arthritis of the great toe and has been used in over 4,000 cases. The purpose of this study was to systematically review the clinical evidence supporting the use of a PVA implant in hallux rigidus. Methods: A systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA). Using the terms “cartiva OR polyvinyl alcohol OR synthetic cartilage OR hemiarthroplasty AND hallux rigidus OR great toe arthritis OR first toe arthritis “ we searched the PubMed/Medline database in December 2017. In addition, the reference list of publications were scanned for further relevant studies. Results: 4 studies met the inclusion criteria, all of which were derived from a single randomized controlled trial. At short-term follow-up (2 years), patients undergoing placement of a PVA implant had significant improvement in Foot and Ankle Ability Measure (FAAM) sports and activity of daily living, as well as VAS pain scores. The outcomes of the surgery were found to be noninferior compared to arthrodesis. At intermediate follow-up (5 years), the improvement in clinical outcomes persisted and implant survivorship was 96%. Conclusion: There are limited studies available detailing the outcomes of a PVA implant for hallux rigidus, however the results that are available demonstrate a high level of evidence. There are no long-term publications assessing the outcomes of a PVA implant for hallux rigidus.

Introduction. Managing fractures of distal tibia is still a subject of debate for orthopaedic surgeons in terms of both, reduction and fixation. Subcutaneous location and soft tissue anatomy predisposes it to angular and rotational instability as well as other bony and soft tissue complexities. Minimally invasive plating offers many advantages over conventional open techniques. It causes minimal soft tissue dissection and surgical trauma to the bone. Minimally invasive plate osteosynthesis(MIPO) maintains biological configuration of distal tibia and fracture hematoma and also provides a construct, which is biomechanically more stable. Objectives. Evaluation of results of MIPO in management of distal tibia fractures considering radiological union, ankle function restoration, and complications. Materials and Methods. In our study, 25 closed distal one-third tibia fracture with/without articular extension were taken, fulfilling the inclusion criteria (AO classification: 10, 43A1; 3, 43A2; 2, 43B1; 4, 43B2; and 6, 43C1). MIPO with locking plates was the treatment undertaken. Patients were followed up for 18 months prospectively. Results. Average injury-hospital interval was 11.16 hours and average injury-operation interval was 2.44 days. All fractures showed radiological union at an average duration of 20.5 weeks (14-28 weeks). Olerud and Molander score was used for evaluation at 3, 6, and 18 months. One patient had union with valgus angulation >5° but there was no nonunion. There was 1 superficial postoperative wound infection. Conclusion. Our study shows that plating with MIPO is an effective treatment for closed distal one-third tibia fractures, considering union time and complications rate. Younger age promotes early union and functional recovery. Levels of Evidence: Therapeutic, Level II: Prospective
