G Mattiassich, W Litzlbauer, M Ponschab, R Ortmaier, C Rodemund
OBJECTIVE: Open treatment of calcaneus fractures often has an increased risk of wound healing. Minimally invasive treatment with small incisions reduces complications. INDICATIONS: Calcaneal fractures with malalignment/comminution >1-2 mm; broadening, varus alignment of the calcaneal length axis or shortening; emergency surgery for open fractures or compartment syndrome. CONTRAINDICATIONS: Local or general contraindications. SURGICAL TECHNIQUE: Standardised positioning; restoration of length/axis with 2‑point distractor under fluoroscopic control...

The purpose of this study was to determine the long-time and transient characteristics of the moment generated by external (ER) and internal (IR) rotation of the calcaneus with respect to the tibia. Two human cadaver legs were disarticulated at the knee joint while maintaining the connective tissue between the tibia and fibula. An axial rotation of 21° was applied to the proximal tibia to generate either ER or IR while the fibula was unconstrained and the calcaneus was permitted to translate in the transverse plane...

A 52-year-old male complained of numbness and radiating pain affecting the plantar region of his left foot. He was found to have recurrent tarsal tunnel syndrome due to posterior tibial nerve compression by 3 different types of ganglion during a 12-year period. To the best of our knowledge, a similar case has not been documented. At the first operation, flexor retinaculum release and simple excision of an epineural ganglion were performed without injuring the nerve fascicles; however, an intrafascicular ganglion developed approximately 2 years later...

AIMS: To assess the effect of high tibial and distal femoral osteotomies (HTO and DFO) on the pressure characteristics of the ankle joint. MATERIALS AND METHODS: Varus and valgus malalignment of the knee was simulated in human cadaver full-length legs. Testing included four measurements: baseline malalignment, 5° and 10° re-aligning osteotomy, and control baseline malalignment. For HTO, testing was rerun with the subtalar joint fixed. In order to represent half body weight, a 300 N force was applied onto the femoral head...

Charcot's neuroarthropathy can have devastating consequences if left untreated or misdiagnosed. With progression of the disease from the acute to the chronic phase, substantial deformity and instability may result, leading to ulceration and a nonfunctional limb. The purpose of this case report is to present a staged reconstruction for active Charcot's neuroarthropathy involving the subtalar joint with complete dislocation that resulted in limb salvage and maintenance of limb function at 1-year follow-up. Although for many patients the mainstay of treatment for early Charcot's neuroarthropathy is conservative care with off-loading, early surgical correction that includes external fixation followed by definitive arthrodesis for select patients may be warranted...

PURPOSE OF THE STUDY Peripheral fractures of the talus (lateral talar process and posterior talar process) are rare injuries, easy to miss on examination due to their location and clinical manifestation. They account for 0.3% to 1.0% of all fractures of the talus. An incorrect or late treatment of talar process fractures can result in permanent pain, impingement syndrome, healing in malposition, pseudoarthrosis development and also, due to joint instability, in a potential development of severe subtalar arthritis...

We present the first known case of cyst fluid localized to an articular branch without involvement of the larger parent nerve. During a routine tarsal tunnel decompression in a patient with fluctuating plantar foot symptoms and "normal" magnetic resonance imaging findings, we identified cyst fluid within an articular branch of the lateral plantar nerve to the subtalar joint. Our incidental intraoperative discovery was corroborated by retrospective review of the magnetic resonance images. Although we do not know whether this cyst was responsible for the patient's complaints, we believe this finding represents a snapshot into the life cycle of intraneural ganglion cysts: either the "birth" of an ultra-early one or the remnant of a once larger one...

Total ankle replacement (TAR) is an accepted treatment for end-stage ankle arthritis. When concurrent subtalar joint pathologic features exist, ipsilateral subtalar joint arthrodesis (STJA) can be performed either simultaneous with TAR or as a staged procedure. Limited data exist on the effect of talar component subsidence and prosthesis survivorship. The present study purpose was to evaluate the effect of STJA on talar component subsidence after primary TAR and its effect on TAR survivorship. All patients, a minimum of 18 years old, from a single institution with modern-generation TAR and 1-year minimum follow-up data available were evaluated...

Musculoskeletal modeling and simulation techniques have been used to gain insights into movement disabilities for many populations, such as ambulatory children with cerebral palsy (CP). The individuals who can benefit from these techniques are often limited to those who can walk without assistive devices, due to challenges in accurately modeling these devices. Specifically, many children with CP require the use of ankle-foot orthoses (AFOs) to improve their walking ability, and modeling these devices is important to understand their role in walking mechanics...

BACKGROUND: Subtalar instability is associated with up to 80% of patients presenting with chronic ankle instability but is often not considered in the diagnosis or treatment. Operative procedures to repair ankle instability have shown good clinical results, but the effects of these reconstruction procedures on isolated subtalar instability are not well understood. The goal of this study was to investigate the effect of the Gould modification of the Broström procedure and a new tenodesis reconstruction procedure on ankle and subtalar joint kinematics after simulating a subtalar injury...

BACKGROUND: Verifying the exact location of talocalcaneal (TC) coalition is important for surgery, but the complicated anatomy of the subtalar joint makes it difficult to visualize on radiographs. No study has used computed tomography (CT) or magnetic resonance imaging (MRI) to verify the radiological characteristics of TC coalition or those of different facet coalitions. Therefore, this study verified the radiological findings used to identify TC coalitions and those of different facet coalitions using CT and MRI...

: Displaced, intra-articular fractures of the calcaneus result in gross deformity of the hindfoot, which must be reduced during surgical fixation. Described techniques aimed at restoring the normal anatomy of the calcaneus have mostly been focused on percutaneous methods, which are not without complication. Described in this report is a method of anatomic reduction during open reduction and internal fixation of these injuries, which uses a lamina spreader to simultaneously reduce calcaneal varus, restore calcaneal height, reduce the subtalar joint, and restore normal calcaneal width...

Coccidioidomycosis is an insidious infection caused by Coccidioides spp (C. immitis and C. posadasii). Disseminated disease occasionally involves tendon sheaths and synovium of the joints leading to tenosynovitis. Here, we describe the case of a 72-year-old woman from southern Arizona, who presented with right ankle pain, redness and swelling for 2 months. Her serum IgG was positive for C. immitis on complement fixation, and her MRI of the right ankle joint showed extensive tenosynovitis of the right peroneal tendons, and subtalar joint effusions with associated synovitis...

BACKGROUND: Subtalar arthritis is a common consequence following calcaneal fracture, and its development is related to the severity of the fracture. Previous calcaneal fracture models have demonstrated altered contact characteristics when a step-off is created in the posterior facet articular surface. Changes in posterior facet contact characteristics have not been previously characterized for calcaneal fracture gap without step-off. METHODS: The contact characteristics (peak pressure, area of contact, and centroid of pressure) of the posterior facet of the subtalar joint were determined in 6 cadaveric specimens...

BACKGROUND: Extensile open approaches to reduce and fix intra-articular calcaneal fractures are associated with high levels of wound complications. To avoid these complications, a technique of percutaneous reduction and fixation with screws alone was developed. This study assessed the clinical outcomes, radiographs, and postoperative CT scans after operative treatment with this technique. METHODS: 153 consecutive patients with 182 intra-articular calcaneal fractures were reviewed...

Posterior ankle pain is a cause of chronic pain and disability, afflicting a wide range of individuals. While proper identification of the cause is essential for timely and adequate treatment, identifying the cause and excluding mimickers is often challenging for the physician due to the complex nature of the joint. In addition, pathology that can cause posterior ankle pain may occur on their own or in co-existence. Clinical conditions that can present as posterior ankle pain include: posterior ankle impingement, Achilles tendon pathology, medial flexor tendon pathology, peroneal pathology, retrocalcaneal bursitis, posterior subtalar tarsal coalition, sinus tarsi, and tarsal tunnel syndrome...

BACKGROUND AND PURPOSE: Lower extremity osteoarthritis (OA) is a common condition among older adults; given the risks of surgical and pharmaceutical interventions, conservative, lower-cost management options such as footwear warrant further investigation. This systematic review investigated the effects of footwear, including shoe inserts, in reducing lower extremity joint pain and improving gait, mobility, and quality of life in older adults with OA. METHODS: The CINAHL, SPORTDiscus, PubMed, RECAL, and Web of Knowledge databases were searched for publications from January 1990 to September 2014, using the terms "footwear," "shoes," "gait," "pain," and "older adult...
