Use of Tibial Cortical Autograft for the Osteotomy Site in Medial Opening-Wedge High Tibial Osteotomy.

Background: Medial opening-wedge high tibial osteotomy (OWHTO) is a useful treatment option in patients with medial compartment osteoarthritis. Typically, the osteotomy site is filled with material such as autologous bone graft, allograft, or synthetic bone substitute. However, all these options have disadvantages.

Tibial cancellous bone auto-grafting for medial open-wedge high tibial osteotomy: bone void filling with tissue harvested from osteotomized medullary canal.

The aim of the study was to evaluate the clinical and radiological outcomes in a series of patients undergoing open wedge high tibial osteotomy (OWHTO) using tibial cancellous autograft harvested from the osteotomized medullary canal which is not reported in the literature before. Patients with medial compartment osteoarthritis were treated with OWHTO and tibial cancellous auto- grafting performed from the osteotomized medullary canal and used for bone void filling. Seventy patients (seventy-two knees) treated with OWHTO were analyzed.

Humeral fractures sustained during arm wrestling.

Purpose: The aim of this study was to present our experience of treating humerus fracture sustained during arm wrestling.

Methods: Data of patients treated in our clinic with the diagnosis of humeral shaft fracture due to arm wrestling between 2000 and 2020 was retrospectively reviewed. Data collected included age, sex, dominant arm, history of professional or experienced participation, type and laterality of fracture, presence of radial nerve palsy, other surgical complications, management (surgical or conservative), duration of union defined as the time from injury until callus was evident on the radiograph, and the range of motion of the elbow joint at the last follow-up.

Skeletal muscle patch engineering on synthetic and acellular human skeletal muscle originated scaffolds.

The reconstruction of skeletal muscle tissue is currently performed by transplanting a muscle tissue graft from local or distant sites of the patient's body, but this practice leads to donor site morbidity in case of large defects. With the aim of providing an alternative treatment approach, skeletal muscle tissue formation potential of human myoblasts and human menstrual blood derived mesenchymal stem cells (hMB-MSCs) on synthetic [poly(l-lactide-co-caprolactone), 70:30] scaffolds with oriented microfibers, human muscle extracellular matrix (ECM), and their hybrids was investigated in this study. The reactive muscle ECM pieces were chemically crosslinked to the synthetic scaffolds to produce the hybrids.

Treatment of Femur Fractures in Preschool Children with Double Pin Technique: Immediate Incorporated Hip Spica Casting by Two K-Wires.

The immediate hip spica casting is a popular treatment method for femoral fractures in the pediatric age group. Femoral shortening is the unacceptable result for the treatment. In this technique, we tried to describe the immediate spica casting technique pinning with double K-wire in preschool children and evaluate the results with this method.

Arthroscopic fixation with intra-articular button for tibial intercondylar eminence fractures in skeletally immature patients.

The aim of this study was to describe our experiences with arthroscopy-guided intra-articular button fixation in the treatment of displaced tibial eminence fractures in skeletally immature children. Eleven adolescent patients with an average age of 12.2 years were treated arthroscopically between January 2005 and February 2007.

Treatment of calcaneal fractures with closed reduction and the Endobutton-assisted technique: short-term analysis.

Background: Closed reduction and percutaneous pinning, open reduction and internal fixation, and primary arthrodesis are procedures used in the surgical treatment of calcaneal fractures. This study presents short-term clinical and radiologic results of patients with calcaneal fractures treated by closed indirect reduction with Endobutton-assisted minimally invasive osteosynthesis.

Methods: Twenty-one feet of 18 patients (four women and 14 men) with calcaneal fractures were retrospectively analyzed.

A new isometric quadriceps-strengthening exercise using EMG-biofeedback.

A new isometric contraction quadriceps-strengthening exercise was developed to restore the quadriceps strength lost after knee surgery more rapidly. This study evaluated the results of this new method. Patients were taught to perform the isometric quadriceps-strengthening exercise in the unaffected knee in the supine position, and then they performed it in the affected knee.

Treatment for painful bone marrow edema by open wedge tibial osteotomy.

We evaluated the results of patients who had undergone medial open wedge proximal tibial osteotomy, with painful bone marrow edema in the medial tibial plateau. The study included 21 patients who had presented with knee pain and whose MRIs showed bone marrow edema in medial plateau. The degree of osteoarthritis was evaluated radiologically according to the Kellgren-Lawrence criteria; 6 cases were Grade 1, 11 cases were Grade 2, and 3 cases were Grade 3.

A minimally invasive technique for the reduction of calcaneal fractures using the Endobutton®.

Calcaneal fractures are very common injuries, and closed reduction-percutaneous pinning, open reduction-internal fixation, and primary arthrodesis are the procedures used in the surgical treatment of these injuries. The aim of surgical treatment is to restore the normal biomechanics of the Achilles tendon and rearfoot by anatomic reduction of the articular surfaces. Minimization of the soft tissue complications commonly associated with the open treatment of calcaneal fractures can be achieved using indirect closed reduction and Kirschner wire or screw-assisted minimally invasive percutaneous osteosynthesis methods.

A comparison of intramedullary nailing and plate-screw fixation in the treatment for ipsilateral fracture of the hip and femoral shaft.

We compared the outcomes of intramedullary nailing with plate-screw fixation in the treatment for ipsilateral fracture of the hip and femoral shaft. A retrospective study. Level 1 Trauma.

Isolated avulsion fracture of lesser tuberosity of the humerus: Review of the literature and report of two cases.

Two cases of acute isolated avulsion fracture of the lesser tuberosity of the humerus and their short-term outcome are presented with a review of previously reported cases. Open reduction and internal fixation was performed. Outcomes were excellent, and the patients regained their normal pain-free shoulder function 3 months after the operation.

Revision of the Gunston polycentric knee arthroplasty with total knee arthroplasty.

The Gunston polycentric knee arthroplasty, first designed and performed by Frank Gunston in 1971, is the first prosthesis considering the natural knee biomechanics. Although the polycentric knee arthroplasty showed encouraging results to relieve pain and to preserve the preoperative range of motion and joint instability, the improvements in prosthesis design and arthroplasty technology rapidly made the polycentric knee prosthesis obsolete. Herein, we report a 58-year old male patient who had revision of the Gunston polycentric knee arthroplasty with total knee arthroplasty performed 32 years after the initial operation.

Distraction osteogenesis is inhibited by cancer radiotherapy with Co 60.

Aim: To investigate the effects of radiotherapy on distraction osteogenesis performed on the same bone in an area that has not received radiation. Radiotherapy (Co60) was carried out in a region where tumors may develop, and then, on the assumption that the tumoral region had been removed, distraction osteogenesis was carried out, and the effects were investigated.

Method: Thirty New Zealand rabbits were randomized into two groups, a study group (15 rabbits) and a control group (15 rabbits).

The role of melatonin as a link between head injury and enhanced osteogenesis.

We hypothesize that in the case of an individual with a head injury, melatonin can enhance osteogenesis. In virtually all species to date whether nocturnal or diurnal, melatonin is synthesized and secreted during the dark phase of the day. In traumatic subarachnoid hemorrhages, in the hypothalamic syndrome, the melatonin content was very high in liquor.

Treatment of refracture occurring after external fixation in paediatric femoral fractures.

With a mean follow-up of four years, we assessed the outcomes of 11 refractures which occurred following paediatric femoral fractures treated by external fixation; the refractures were treated conservatively with simple immobilisation in a spica cast. A total number of 104 children with a femoral fracture were treated with external fixation between 1993 and 2000 in our institution. Refracture occurred in 11 cases after fixator removal.

Early prophylactic autogenous bone grafting in type III open tibial fractures.

The authors report the results achieved in patients with type III open tibial fractures who underwent primary autogenous bone grafting at the time of debridement and skeletal stabilisation. Twenty patients with a mean age of 35.8 years (range, 24-55) were treated between 1996 and 1999.

Is external fixation in pediatric femoral fractures a risk factor for refracture?

The aim of this study was to investigate whether external fixation is a risk factor for refracture by comparing the outcomes of children who received three different forms of treatment of femoral fractures. One hundred ninety-two patients treated for femoral fracture between 1990 and 1999 who underwent final examination were assessed. One hundred were treated with hip spica casting after traction, 57 with closed reduction and external fixation, and 35 with open reduction and external fixation.

The effects of electromagnetic field on distraction osteogenesis.

The effects of electromagnetic field on distraction osteogenesis and new bony tissue were investigated. Twenty-five New Zealand rabbits were divided into an experimental (12 rabbits) and a control (13 rabbits) group. An osteotomy was performed on the right tibia in the diaphyseal region in both groups.

Anthropometric study of patients treated for clubfoot.

The anthropometric characteristics of patients treated for clubfoot were used to investigate whether the dimensions of the foot were affected by the method of treatment. A total of 68 patients followed up for an average of 9 years were divided into three groups: group 1, conservatively treated; group 2, surgically treated; group 3, conservatively treated on one side and surgically treated on the other. The following average discrepancies in foot length were obtained: group 1, 0.
