Comparison of Direct Repair Versus Anatomic Graft Reconstruction of the Anterior Talofibular Ligament: A Biomechanical Cadaveric Study.

The goal of our study is to compare the stability of the anatomic reconstruction of the anterior talofibular ligament (ATFL) with direct repair of the ATFL, in a cadaver model. We performed the following techniques in 18 cadaveric ankles: the intact ATFL was cut, after which a direct repair using 2 anchors was performed. The repair was sectioned, and anatomic reconstruction was then performed with a tendon autograft.

Long-term outcomes of distal locking in extracapsular fractures treated with trochanteric Gamma3 nails.

Background: Few publications have assessed long-term results of distal locking of short endomedullary nails for extracapsular hip fracture. Virtually all of them focus on immediate differences. Criteria for the use of static or dynamic locking are unclear in most nailing systems, and use is advised in unstable fracture patterns or with risk of bell-clapper effect, but often influenced by the "orthopaedic school".

Hip fracture care and mortality among patients treated in dedicated COVID-19 and non-COVID-19 circuits.

Introduction: To analyze the effect of the COVID-19 pandemic on the provision of fragility hip fracture care, comparing patients treated before cohorting and in separate COVID-19 and non-COVID-19 circuits with the corresponding months in 2018 and 2019.

Materials And Methods: Retrospective single-center cohort study including 64 patients with fragility hip fractures treated during the COVID-19 pandemic (March 1st-May 1st, 2020), compared to 172 patients treated in 2018 and 2019. Dedicated COVID-19 and non-COVID-19 circuits were established on March 14th.

Decreased volume of hip fractures observed during COVID-19 lockdown.

Introduction: The aim was to study the incidence and characteristics of fragility hip fractures admitted during COVID-19 lockdown.

Materials And Methods: We analysed socio-demographic and baseline characteristics of patients suffering fragility hip fractures between March 1st and May 1st 2020, period most affected by COVID-19 confinement measures. Cases (n = 64) were compared with controls (n = 172) from corresponding periods in 2018 and 2019.

Biomechanical study of autograft anatomic reconstruction in lateral ankle instability.

Introduction: The purpose of this work is perform a biomechanical comparison of anatomic reconstruction of the anterior talofibular ligament (ATFL) with the intact ATFL.

Materials And Methods: We studied 18 fresh cadaveric ankles with intact ATFL. Each specimen was clinically assessed with the anterior drawer (AD) and varus tilt (VT) tests and the angular movement in the three spatial planes (axial, coronal and sagittal) was measured with an arthrometer using a sensor located in the talus.

Correlation between radiographic findings and clinical failure in monopolar radial head replacement.

Introduction: The purpose of this study is to analyze the mid-term outcomes of a modular monopolar type of radial head arthroplasty in the treatment of complex fractures associated with acute elbow joint instability. We postulated that radiographic changes are related to the development of clinical complications.

Materials And Methods: We evaluated at last follow-up 26 radial head arthroplasties in 26 consecutive patients who were followed for at least one and a half year.

Denosumab treatment for giant-cell tumor of bone: a systematic review of the literature.

Background: Denosumab is a human monoclonal antibody (mAb) that specifically inhibits tumor-associated bone lysis through the RANKL pathway and has been used as neoadjuvant therapy for giant-cell tumor of bone (GCTB) in surgical as well as non-surgical cases. The purpose of this systematic review of the literature, therefore, is to investigate: (1) demographic characteristics of patients affected by GCTBs treated with denosumab and the clinical impact, as well as, possible complications associated with its use (2) oncological outcomes in terms of local recurrence rate (LRR) and development of lung metastasis, and (3) characteristics of its treatment effect in terms of clinical, radiological, and histological response.

Methods: A systematic review of the literature was conducted using PubMed, EMBASE, and COCHRANE search including the following terms and Boolean operators: "Denosumab" AND "primary bone tumor", "denosumab" AND "giant cell tumor", "denosumab" AND "treatment", and finally, "denosumab" AND "giant cell tumor" AND "treatment" since 2000.

Clinical and imaging effects of corticosteroids and platelet-rich plasma for the treatment of chronic plantar fasciitis: A comparative non randomized prospective study.

The purpose is to compare the effectiveness and imaging changes (US and MRI) between PRP and corticoids injections for the treatment of chronic plantar fasciitis, using clinical results evaluated by the visual analogue scale (VAS), the AOFAS clinical rating system and the modified Roles and Maudsley score, and using imaging results (US and MRI). Our hypothesis is that PRP infiltrations are a more effective therapeutic method than infiltrations with corticosteroids. A single-centre, non randomized, prospective study of 40 consecutive patients (40 feet) with plantar fasciitis who had not responded to conservative treatment for at least 6 months was undertaken.

Arthroscopic posterior subtalar arthrodesis for salvage of posttraumatic arthritis following calcaneal fractures.

Background: Subtalar arthrodesis is a treatment option for pain due to posttraumatic arthritis following calcaneal fractures. The goal of this study is to examine the results of arthroscopic subtalar arthrodesis for posttraumatic arthritis following calcaneal fractures.

Patients And Methods: We performed a retrospective case series reviewing 37 consecutive patients (36 male) treated for posttraumatic arthritis following calcaneal fractures by arthroscopic subtalar arthrodesis.

Nonsurgical Treatment as Alternative to Surgical Treatment in Enchondromas of the Distal Phalanx. Analysis of a Series of 11 Cases.

Purpose: To describe the results of nonsurgical and surgical treatment of enchondromas of the distal phalanx of the hand.

Methods: Eleven enchondromas of the distal phalanx were retrospectively reviewed. Five patients underwent surgery (curettage and autogenous cancellous bone graft from the iliac crest) and 6 patients were treated nonsurgically.

Aggressive curettage of a chondroblastoma-like osteosarcoma of the proximal end of the tibia. A case report with seven-year follow-up.

A chondroblastoma-like osteosarcoma (CLO) in the proximal epiphysis and metaphysis of the tibia in a 30-year-old male is presented. With a wrong diagnosis of chondroblastoma, an aggressive curettage was performed. Later, the patient refused en-bloc resection.

Early diagnosis of systemic amyloidosis by means of a transverse carpal ligament biopsy carried out during carpal tunnel syndrome surgery.

Introduction And Objective: The systematic analysis of a carpal transverse ligament (CTL) sample obtained during routine carpal tunnel syndrome (CTS) surgery may constitute a method of early diagnosis for systemic amyloidosis.

Material And Methods: Prospective study carried out on 147 consecutive CTL samples collected from patients intervened for CTS at the University Hospital of León from April 2006 to May 2007. In those cases in which amyloid deposition was observed in the CTL sample, the study was completed with a fine needle aspiration biopsy (FNAB) of the subcutaneous fascia, using the Red Congo stain in both cases.

Bursectomy, Curettage, and Chemotherapy in Tuberculous Trochanteric Bursitis.

We presented three patients with trochanteric tuberculosis and described the clinical and imaging findings of the infection. Histology revealed a necrotizing granulomatous bursitis and microbiology confirmed tuberculosis. All cases were successfully treated with bursectomy and curettage of the trochanteric lesion and antituberculous chemotherapy including isoniazid, pyrazinamide, rifampicin, and ethambutol.

Polyostotic fibrous dysplasia associated with intramuscular myxomas: Mazabraud syndrome.

The authors report a new case of Mazabraud syndrome in a 69-year-old woman complaining of pain in her right thigh. Plain radiographs demonstrated radiological findings consistent with polyostotic fibrous dysplasia of the right femur and tibia. Magnetic resonance imaging (MRI) study showed soft tissue tumors located in the vastus intermedius muscle with typical signal features of intramuscular myxomas.

Investigating a potential biological treatment to prevent pathological fractures caused by unicameral bone cysts in children under 8 years.

Introduction: There is no consensus on when and how to treat unicameral bone cysts (UBCs), partly because of a lack of knowledge of the aetiology.

Purpose: To review the different treatment techniques for UBCs and to describe our results with a single injection of autogenous bone marrow (BM) mixed with demineralised bone matrix (DBM) in very young children.

Patients And Methods: We reviewed five patients under the age of 8 years with UBCs treated by percutaneous aspiration and a single injection of BM associated with DBM.

Ewing sarcoma of the first metacarpal with a 9-year follow-up: case report.

Ewing sarcoma is a primary bone tumor that rarely occurs in the hand. We present a case involving the thumb metacarpal with long-term follow-up. Carpometacarpal and metacarpophalangeal arthrodeses with autograft are relatively simple procedures that stabilized the thumb and preserved satisfactory function.

Intracortical chondromyxoid fibroma of the tibia.

Intracortical chondromyxoid fibroma is an extremely rare benign neoplasm of cartilaginous origin that usually occurs as an eccentric lesion at the medullar metaphyseal region of long bones. We report the clinicoradiologic aspect of a new case located in the metaphyseal region of the upper tibia and discuss about the differential diagnosis.
