#1
Phinit Phisitkul, Vinay Hosuru Siddappa, Tinnart Sittapairoj, Jessica E Goetz, Bryan D Den Hartog, John E Femino
BACKGROUND: Access to the plantar plate has been described using either a plantar approach or an extensive dorsal approach that required complete joint destabilization and often a metatarsal osteotomy. Clinical scenarios related to plantar plate tear vary and the pathologies in early stages are frequently limited to unilateral soft tissue structures; a less invasive operative approach may be possible. A novel approach requiring a release of only the lateral collateral ligament and the lateral half of the plantar plate is presented in this cadaver model; the extent of joint exposure possible is described...

Elissa S Finkler, Daniel A Marchwiany, Adam P Schiff, Michael S Pinzur
BACKGROUND: The metabolic cost of walking after Syme's ankle disarticulation amputation is minimally more than that for nonamputation. The ability to end weightbearing makes prosthetic fitting relatively simple, and very few patients require extensive rehabilitation or placement in a skilled nursing or rehabilitation facility. In spite of these potential benefits, there is a paucity of objective information on the actual long-term outcomes. METHODS: Fifty-one patients were identified who underwent single-stage Syme's ankle disarticulation amputation with excision of the lateral and medial malleoli by a single surgeon during a 23-year period...

Lyle T Jackson, Linda J Dunaway, Gregory A Lundeen
BACKGROUND: Traumatic tears of the tibialis posterior (TP) tendon following an ankle sprain are rare. The purpose of this study was to report our case series of TP tendon tears following an ankle sprain. METHODS: Patients with persistent TP tendon pain after an ankle sprain were retrospectively identified over a 4-year period and reviewed. A comparison of magnetic resonance imaging (MRI) interpretations by a radiologist and surgeon was made. Patients failing conservative management underwent operative repair of the TP tendon tear and concomitant pathology...

BACKGROUND: An intra-articular injection of platelet-rich plasma (PRP) may be an effective treatment for osteoarthritis (OA). However, its efficacy in ankle OA has not been investigated yet. The purpose of this study was to assess the safety and efficacy of an intra-articular injection of PRP in patients with ankle OA during a 24-week period. METHODS: Twenty ankles of 20 patients with varus-type ankle OA who received intra-articular injections of PRP were evaluated...

#5
Damjan Dimnjaković, Pero Hrabač, Ivan Bojanić
BACKGROUND: A tourniquet is usually used during anterior ankle arthroscopy to allow for improved visibility and reduced operation time. However, this has not been demonstrated to be true in clinical studies on knee arthroscopy, while limited tourniquet time has been described as a possible factor to lower the complication rate of ankle arthroscopy. The purpose of this randomized controlled trial was to examine the effect of tourniquet use on arthroscopic visualization, operative time, postoperative intra-articular bleeding, postoperative pain scores, and outcome of anterior ankle arthroscopy...

BACKGROUND: Investigations using the Medical Outcomes Study Short Form 36 Healthy Survey (SF-36) and the American Orthopaedic Foot & Ankle Society Diabetic Foot Questionnaire (AOFAS-DFQ) have demonstrated a poor quality of life in patients with Charcot foot arthropathy. The Short Musculoskeletal Function Assessment (SMFA) questionnaire has been widely used in patients with a broad range of musculoskeletal disorders. METHODS: Twenty-five consecutive patients undergoing operative correction for diabetes-related Charcot foot arthropathy of the midfoot completed the SMFA prior to undergoing surgery...

Lindsy Donnelly, Luke Donovan, Joseph M Hart, Jay Hertel
BACKGROUND: Individuals with chronic ankle instability (CAI) have demonstrated strength deficits compared to healthy controls; however, the influence of ankle position on force measures and surface electromyography (sEMG) activation of the peroneus longus and brevis has not been investigated. The purpose of this study was to compare sEMG amplitudes of the peroneus longus and brevis and eversion force measures in 2 testing positions, neutral and plantarflexion, in groups with and without CAI...

Young Hwan Park, Chan Dong Jeong, Gi Won Choi, Hak Jun Kim
BACKGROUND: Bipartite hallucal sesamoids are often found in patients with hallux valgus. However, it is unknown whether bipartite hallucal sesamoids affect the results of hallux valgus surgery or not. The purpose of the present study was to evaluate the outcomes of chevron osteotomy for hallux valgus with and without bipartite hallucal sesamoid. METHODS: A total of 152 patients (168 feet) treated with distal or proximal chevron osteotomy for hallux valgus constituted the study cohort...

Osteochondral lesions of the talus (OLTs) are an increasingly implicated cause of ankle pain and instability. Several treatment methods exist with varying clinical outcomes. Due in part to successful osteochondral allografting (OCA) in other joints, such as the knee and shoulder, OCA has gained popularity as a treatment option, especially in the setting of large lesions. The clinical outcomes of talar OCA have been inconsistent relative to the positive results observed in other joints. Current literature regarding OCA failure focuses mainly on 3 factors: the effect of graft storage conditions on chondrocyte viability, graft/lesion size, and operative technique...

BACKGROUND: Hindfoot fractures pose a considerable challenge to military orthopaedic surgeons, as combat injuries are typically the result of energy transfers not seen in civilian practice. This study aimed to characterize the pattern of hindfoot injuries sustained by UK military casualties in recent conflicts, define the early amputation and infection rate, and identify factors associated with poor early outcomes. METHODS: The UK Joint Theatre Trauma Registry was searched for British military casualties sustaining a hindfoot fracture from Iraq and Afghanistan between 2003 and 2014...

BACKGROUND: Bone marrow edema syndrome (BMOS) is a phenomenon primarily affecting the lower extremity. It is characterized by a sudden onset of pain and an ill-defined osseous hyperintense signal in magnetic resonance imaging. The main cause of BMOS is still largely unknown. Its pathophysiology is presumably multifactorial and it has recently been demonstrated that it usually involves an increase in bone turnover and alterations within the bone microenvironment. Vitamin D plays a pivotal role in maintaining a healthy and well-balanced bone microenvironment...

BACKGROUND: Traumatic hallux valgus is an increasingly common injury in the athletic population and represents a unique variant of turf toe. Failure to appropriately recognize and treat these injuries can lead to continued pain, decreased performance, progressive deformities, and ultimately degeneration of the hallux metatarsophalangeal joint. Limited literature currently exists to assist in the diagnosis, management, and operative treatment. METHODS: Nineteen patients were reviewed in this series, including 12 National Football League, 6 college, and 1 high school player who was a college prospect...

BACKGROUND: Recurrent pain and deformity following forefoot surgery can cause significant patient disability. In patients with rheumatoid arthritis, first metatarsophalangeal (MTP) joint arthrodesis with lesser metatarsal head resections-termed the rheumatoid forefoot reconstruction-has been shown to be a reliable operation for pain relief and deformity correction. Limited data, however, have been published on outcomes of the same forefoot reconstruction operation in the nonrheumatoid patient...

Dong-Kyo Seo, Ho Seong Lee, Jungu Park, Chang Hyun Ryu, Duck Jong Han, Sang Gyo Seo
BACKGROUND: It is known that successful pancreas transplantation enables patients with diabetes to maintain a normal glucose level without insulin and reduces diabetes-related complications. However, we have little information about the foot-specific morbidity in patients who have undergone successful pancreas transplantation. The purpose of this study was to investigate the prevalence and predisposing factors for foot complications after successful pancreas transplantation. METHODS: This retrospective study included 218 patients (91 males, 127 females) who had undergone pancreas transplantation for diabetes...

BACKGROUND: Syndesmotic injuries can be associated with poor patient outcomes and posttraumatic ankle arthritis, particularly in the case of malreduction. However, ankle joint contact mechanics following a syndesmotic injury and reduction remains poorly understood. The purpose of this study was to characterize the effects of a syndesmotic injury and reduction techniques on ankle joint contact mechanics in a biomechanical model. METHODS: Ten cadaveric whole lower leg specimens with undisturbed proximal tibiofibular joints were prepared and tested in this study...

Christopher P Miller, Mohammad Ghorbanhoseini, Lauren K Ehrlichman, Kempland C Walley, Azadeh Ghaheri, John Y Kwon
BACKGROUND: Weight-bearing radiographs are a critical component of evaluating foot and ankle pathology. An underlying assumption is that patients are placing 50% of their body weight on the affected foot during image acquisition. The accuracy of weight bearing during radiographs is unknown and, presumably, variable, which may result in uncertain ability of the resultant radiographs to appropriately portray the pathology of interest. METHODS: Fifty subjects were tested...

Gennadiy A Busel, J Tracy Watson, Heidi Israel
BACKGROUND: Comminuted fibular fractures can occur with pilon fractures as a result of valgus stress. Transverse fibular fractures can occur with varus deformation. No definitive guide for determining the proper location of tibial fixation exists. The purpose of this study was to identify optimal plate location for fixation of pilon fractures based on the orientation of the fibular fracture. METHODS: One hundred two patients with 103 pilon fractures were identified who were definitively treated at our institution from 2004 to 2013...

BACKGROUND: Few authors have investigated patients' expectations from foot and ankle surgery. In this study, we aimed to examine relationships between patients' preoperative expectations and their demographic and clinical characteristics. We hypothesized that patients with more disability and those with anxiety or depressive symptoms would have greater expectations. METHODS: All adult patients scheduled for elective foot or ankle surgery by 1 of 6 orthopaedic foot and ankle surgeons were screened for inclusion over 8 months...

BACKGROUND: The American Orthopaedic Foot & Ankle Society (AOFAS) score is one of the most common and adapted outcome scales in hallux valgus surgery. However, AOFAS is predominantly physician based and not patient based. Although it may be straightforward to derive statistical significance, it may not equate to the true subjective benefit of the patient's experience. There is a paucity of literature defining MCID for AOFAS in hallux valgus surgery although it could have a great impact on the accuracy of analyzing surgical outcomes...
