Vertebral Body Height Changes in Acute Symptomatic Osteoporotic Vertebral Compression Fractures Treated with Vertebral Cement Augmentation-Which Factors Affect Vertebral Body Height during Follow-up? A Multiple Linear Regression Study.

Changes in vertebral body height depend on various factors which were analyzed in isolation and not as a whole. The aim of this study is to analyze what factors might influence the restoration of the vertebral body height after vertebral augmentation. We analyzed 48 patients (108 vertebrae) with osteoporotic vertebral fractures who underwent vertebral augmentation when a conservative treatment proved to be unsatisfactory.

Hallux anatomy: much ado about shoes-an attempt to prove that constrictive V-shaped toe-box shoes deform the hallux.

Purpose: A question still remains as to whether constrictive toe-box shoes (TBS) cause disability only due to pain on pressure points or if they can cause permanent changes in the hallux anatomy. The aim of this study is to compare the hallux morphology in 3 groups classified according to their use of constrictive or open TBS.

Methods: 424 patients were classified into 3 groups: group A used open TBS daily; group B used constrictive TBS daily; group C used both open and constrictive TBS.

Osteoid osteoma in the ankle and foot. An overview of 50 years of experience.

Background: The literature published about osteoid osteoma (OO) in the ankle-foot consists mainly on case reports.

Methods: We performed a retrospective study in which we analyzed demographic parameters, pain characteristics, treatment options and functional outcomes measured using the AOFAS and the SEFAS scales.

Results: We treated 17 patients with OO around the ankle-foot.

Akin osteotomy: Is the type of staple fixation relevant?

Background: Although different fixation techniques for the Akin osteotomy have been described in the literature, there are no many studies trying to analyze the differences between the types of fixation available. The aim of this study is to analyze if there are any differences between three types of staple fixation available in the market.

Method: We present a retrospective study of 145 cases in which an Akin osteotomy was performed and fixed with three different kinds of implants staple A (28%), staple B (45%), and staple C (27%).

The efficacy of an intramedullary nitinol implant in the correction of claw toe or hammertoe deformities.

Introduction: A multitude of procedures has been described in the literature for the treatment of lesser toe deformities and there is currently no general consensus on the optimal method of fixation. The aim of this study is to assess the clinical and radiological outcomes of an intramedullary nitinol implant for the correction of lesser toe deformities, and to determine if the distal interphalangeal (DIP) joint and metatarsophalangeal (MTP) joint are modified during patient follow-up after correction of the PIP joint.

Materials And Methods: A prospective analysis of 36 patients with claw toe or hammertoe who were treated with an intramedullary nitinol implant.

Feasibility of open and percutaneous corrective osteotomies of the second phalanx of the great toe: An approach on a cadaveric model.

Background: Having had a previous experience of 4 open F2 osteotomies to correct interphalangeal hallux valgus, the aim of this study was to test the efficacy of a percutaneous approach for this correction.

Methods: 3 open and 12 percutaneous F2 osteotomies in 15 cadaver feet were performed. Interphalangeal (IPH), F2 asymmetry (AF2) and joint deviation (JD) angles were measured on radiographs.

Efficacy of pedobarographic analysis to evaluate proximal medial gastrocnemius recession in patients with gastrocnemius tightness and metatarsalgia.

Purpose: Proximal medial gastrocnemius recession (PMGR) is a surgical procedure performed in patients with gastrocnemius tightness (GT). The purpose of this study is to evaluate the efficacy of pedobarographic analysis on PMGR in patients with GT and metatarsalgia.

Methods: This prospective study included 52 patients diagnosed with GT treated surgically with PMGR and 49 non-operated upon patients (control group).

Local and systemic diffusion of antineoplastic drugs following vertebroplasty using acrylic cement mixed with cisplatin or methotrexate: experimental study in pigs.

Purpose: To determine the efficacy of cisplatin- or methotrexate-containing acrylic cement for local and systemic antineoplastic drug diffusion. Among the uses of acrylic cement or Polymethylmethacrylate (PMMA), there is the possibility to employ it as vehicle for drug diffusion. This capability is of interest in the treatment of pathological fractures: The curative effects of the cement (cytotoxicity of the monomer and increased temperature) are added to the antineoplastic effect of the drugs.

Sesamoid Position in Healthy Volunteers Without Deformity: A Computed Tomography Study.

We used coronal computed tomography to determine the normal sesamoid position in 20 healthy volunteers. The sample involved 40 feet (20 left [50%] and 20 right [50%]) in 20 volunteers, including 11 females (55%) and 9 males (45%). The relationship between the first metatarsal head and the sesamoid complex was categorized as Yildirim grade 0 in every case (100%).

The Relationship Between the Sesamoid Complex and the First Metatarsal After Hallux Valgus Surgery Without Lateral Soft-Tissue Release: A Prospective Study.

Some investigators have emphasized restoring the relationship between the sesamoid complex and the first metatarsal head to reduce the risk of hallux valgus recurring after surgical reconstruction. In a prospective study, we analyzed whether the first metatarsophalangeal joint could be realigned after scarf-Akin bunionectomy without lateral soft tissue release. A total of 25 feet, in 22 patients, were prospectively enrolled and analyzed using anteroposterior radiographs and coronal computed tomography scans obtained before and 3 months after surgery.

External validation of a model to predict the survival of patients presenting with a spinal epidural metastasis.

The surgical treatment of spinal metastases is evolving. The major problem is the selection of patients who may benefit from surgical treatment. One of the criteria is an expected survival of at least 3 months.

Dorsal defect of the patella with fracture in a teenager.

We report the case of a young boy who presented a dorsal defect of the patella (DDP) with fracture after a small sport trauma. The patient's parents (professional of health care) had been warned on a possible tumoral disease in a previous consultation and claimed for an accurate diagnosis. Although fracture is rarely reported in DDP, the radiographic image strongly suggested this condition; nevertheless, the diagnosis accuracy requested by the parents lead to indicate a biopsy that showed irregular fragments of laminar bone and hyaline cartilage islands similar to articular cartilage compatible with a non-specific developmental ossification defect.

Symptomatic medial exostosis of the great toe distal phalanx: a complication due to over-correction following akin osteotomy for hallux valgus repair.

Unlabelled: The authors present the case of a 54-year-old female who developed a painful compression lesion localized to the medial aspect of the base of the distal phalanx of the great toe as a complication of hallux valgus surgery. Preoperative radiographic evaluation of the patient's foot revealed the first ray to be longer than the second, a 12 degrees first intermetatarsal angle, a 33 degrees hallux abductus angle, and an exostosis at the medial aspect of the base of the hallux that was not considered by the surgeon to be important. Correction of the hallux valgus deformity was performed with a combination of scarf and Akin osteotomies, and the intermetatarsal and hallux abductus angles reduced to 2 degrees and 8 degrees , respectively.

Neurectomy versus neurolysis for Morton's neuroma.

Background: We evaluated a series of patients who underwent neurectomy or neurolysis for the surgical treatment of Morton's neuroma.

Materials And Methods: A group of 50 patients (69 feet) who underwent surgery for a symptomatic Morton's neuroma were retrospectively reviewed. Surgery was performed through a dorsal approach in all cases.

Study Design: The shape of the L5 vertebral body was analyzed using a computerized tomography (CT) scan.

Objective: The aim of this study is to determine if the vertebral L5 body shape varies depending on the height of the CT slices through the L5 pedicle.

Summary Of Background Data: The morphometry of L5 has been studied to help the introduction of pedicular screws.

Corrosion and late infection causing delayed paraparesis after spinal instrumentation.

A 28-year-old female patient came to our hospital 14 years after surgical correction of adolescent idiopathic scoliosis with a 316L stainless-steel instrumentation. She presented progressive paraparesis during the last 2 months. Plain radiography, computed tomography scan and computed tomography-scan-guided needle biopsy revealed that a metallotic mass penetrated into the spinal canal, causing compression of the spinal cord at the T5-T6 level.

Pure cervical radiculopathy due to spontaneous spinal epidural haematoma (SSEH): report of a case solved conservatively.

Introduction: Spontaneous spinal epidural haematoma (SSEH) is widely recognised throughout the literature as a cause of myelopathy, radicular compression being very rarely reported. Surgical management is almost always recommended, especially in the cases of spinal cord compression. Conservative treatment is reported as a curiosity and only in the case of spontaneous improvement.

Intraoperative radiotherapy electron boost followed by moderate doses of external beam radiotherapy in resected soft-tissue sarcoma of the extremities.

Purpose: To analyze the patterns of failure and the toxicity profile of intraoperative electron beam radiotherapy (IOERT) after resection of soft tissue sarcomas of the extremities (STS).

Patients And Methods: Forty-five patients with extremity STS were treated with IOERT and moderate-dose postoperative radiotherapy (45-50 Gy). Twenty-six patients were treated for primary disease (PD) and 19 patients for an isolated recurrence (ILR).
