BACKGROUND: Shoulder arthroscopic arthrodesis is an uncommon and non-standardized procedure. Results are poorly evaluated. We describe the findings in 8 patients who underwent shoulder arthroscopic arthrodesis for brachial plexus injury. METHODS: The humeral head and glenoid were excised through standard arthroscopic portals. A Hoffmann external fixator and cannulated screws were used to stabilize the shoulder. Standard clinical assessment and radiographic evaluation were performed each month until bony fusion occurred...

INTRODUCTION: The management of ankle fractures in the elderly remains unpredictable, secondary to their various co-morbidities. Although tibiotalocalcaneal (TTC) nailing has been an effective option for ankle arthrodesis due to ankle arthritis or Charcot arthropathy there are few reports regarding the use of TTC nail for the treatment of ankle fractures. PURPOSE: Aim of this study was to compare the results of ORIF versus TTC nailing for the treatment of unstable ankle fractures in the elderly...

INTRODUCTION: PMMA-augmentation of pedicle screws strengthens the bone-screw-interface reducing cut-out risk. Injection of fluid cement bears a higher risk of extravasation, with difficulty of application because of inconsistent viscosity and limited injection time. OBJECTIVE: To test a new method of cement augmentation of pedicle screws using radiofrequency-activated PMMA, which is suspected to be easier to apply and have less extravasations. METHODS: Twenty-seven fresh-frozen human cadaver lumbar spines were divided into 18 osteoporotic (BMD ≤ 0...

INTRODUCTION: There were higher rates of revision, complication, non-union, delayed union, and poorer functional outcomes reported in super-aged patients of undisplaced femoral neck fractures treated with internal fixation. Therefore, we designed this randomized comparative study aiming to compare the effectiveness and long-term follow-up results of hemiarthroplasty (HA) with that of multiple cannulated screws (MCS). MATERIALS AND METHODS: Eligible participants were randomly assigned into two groups for different methods of operation (hemiarthroplasty group and internal fixation group)...

A 34-year-old man with a subtrochanteric osteoid osteoma localized to the lateral cortex of the left femur is reported. The patient presented with mild spontaneous pain of the lateral thigh and knee. He refused a radiographic examination and was treated as a greater trochanteric pain syndrome for 9 months. He was then admitted with a transcervical fracture of the neck of the left femur after a fall from standing height. The fracture was fixed with 3 cannulated screws and healed uneventfully. His symptoms worsened after the first postoperative year...

We report the case of a 15-year-old boy with combined fractures of the scaphoid, capitate, and hamate that represents a rare variation of the well-known Fenton's syndrome. Fixation was performed for the unstable fractures of the scaphoid and capitate with the use of cannulated Herbert screws and K‑wires respectively. K‑wires were removed after 6 months, with subsequent physiotherapy. After 6 months, CT confirmed complete consolidation of the two surgically treated carpal fractures and the conservatively treated fracture of the hamate...

In this study, we present the case of a 42-year-old man with a fracture and dislocation of the left talus neck, and a fracture of the right talus neck due to a fall. This kind of fracture can be considered rare, and thus few cases have been reported. Fracture fixation was provided through cannulated screws on either side. Splints were removed after 6 weeks, and passive/active joint movement exercises were started. The patient was able to walk with partial weightbearing at 2 months and with full weightbearing at 3 months...

Tibial shaft fractures are among the most common long bone fractures in humans. The incidence is 1-2 per 100,000. The gold standard of treatment for AO type 42 A-C fractures is a locking intramedullary nail. The development of new implants has extended the indications for this minimally invasive technique, so that now AO types 41 and 43 can also be treated with special nails. Fixed-angle screw anchors increase primary stability and supplemental locking devices located proximally and distally extend the spectrum of use to metaphyseal fractures...

The treatment of anterior shoulder instability is well described with various techniques, including arthroscopic double-row repair, an alternative to open stabilization procedures in high-risk groups. The surgical management of posterior instability in high-risk and athletic populations is a less-explored entity. We describe our technique for an all arthroscopic double-row suture anchor repair of a large posterior bony Bankart lesion. We prefer this technique over percutaneous cannulated screw fixation because the double-row suture technique allows for incorporation of capsular plication with bony fixation in an effort to better restore normal anatomy for capsulolabral complex...

OBJECTIVES: The current biomechanical work compares the symphyseal and sacroiliac stability obtained with two systems of bone osteosynthesis. The two methods of fixation compared were the 6-hole suprapubic non-locked plate and pubic fixation with two cannulated screws, a novel technique that can be applied percutaneously in the clinical practice. The aim of this study was to examine the validity of the use of two-cannulated-screws osteosynthesis in order to minimize the secondary effects of open fixation, especially in patients in whom an open reduction is contraindicated...

INTRODUCTION: The gradual aging of the population results in increased incidence of osteoporotic bone fractures. In a good quality bone, the fixation with the usual methods is adequate, but not in osteoporotic bone, in which consolidation delays and other complications are common, with failure rates for screws up to 25%. OBJECTIVE: To test fibronectin loaded hydroxyapatite as a complementary treatment for osteoporotic fractures. MATERIAL AND METHODS: This study was performed in a vivo model; 42 female osteoporotic adult rabbits 4-5kg (White New Zealand) were used...
