Greater presence of receptors for relaxin in the ligamentum teres of female infants who undergo open reduction for developmental dysplasia of the hip.

Background: While many factors involved in the etiology of developmental dysplasia of the hip (DDH), one of which is the hormone relaxin. Relaxin concentrations in patients with DDH may lead to pathodynamic changes during hip development by altering the physiological nature of the ligament, as well as by long-term exposure to relaxin during pregnancy. Our objective in this study was to determine the number of relaxin receptors in the ligamentum teres and their role in causing DDH.

Mini-plate fixation via sinus tarsi approach is superior to cannulated screw in intra-articular calcaneal fractures: A prospective randomized study.

Objective: Intra-articular displaced calcaneal fractures are common fractures and are often treated with surgical interventions. Sinüs tarsi approach provides secure access to lateral wall and joint facets. The aim of the study is to compare cannulated screw (CS) fixation and mini-plate (MP) fixation via sinus tarsi approach with Sanders types 2 and 3 fracture of calcaneus.

Association between vitamin D concentrations and knee pain in patients with osteoarthritis.

Objectives: Osteoarthritis (OA) and vitamin D deficiency are common health conditions in older people. Whether vitamin D concentration is associated with knee OA is controversial. In this study, we aimed to determine the association between serum concentrations of vitamin D and osteoarthritic knee pain.

Effects of hyaluronic acid (Hyalonect) on callus formation in rabbits.

Objective: Bone fragment and graft stabilization are important during reconstructive surgery of cases with comminuted fractures and bone defects. We examined the effect of Hyalonect surgical mesh on the healing dynamics of metaphyseal bone defects created in rabbit tibiae.

Methods: Approximately 5-mm defects were created on the anterior aspect of the proximal tibial metaphysis of 80 male rabbits.

The effects of osteoporosis on functional outcome in patients with distal radius fracture treated with plate osteosynthesis.

Objective: The aim of this study was to evaluate the effect of osteoporosis on functional results in patients with distal radius fracture treated with plate osteosynthesis.

Methods: The study included 37 female patients who underwent osteosynthesis using volar locking plate for distal radius fracture between 2006 and 2008. Diagnosis of osteoporosis was made with bone mineral density measurement.

Shoulder arthrodesis with plate fixation.

Objective: The aim of this study was to evaluate the long-term outcome of shoulder arthrodesis with plate fixation and primary autogenous grafting in terms of pain, functional status and arthrodesis position.

Methods: The study included 8 patients (7 males and 1 female; mean age: 39.3 years; range: 22 to 68 years) who underwent arthrodesis with plate fixation and primary autogenous grafting.

Surgical treatment of mallet fractures by extension block Kirschner wire technique surgical treatment of mallet fractures.

Objective: We use the extension block Kirschner wire method that orginated from Ishigura to treat mallet fracture and evaluate its efficiency.

Methods: 38 patients were treated prospectively. Mean follow-up was 18 months and all patients evaluated radiologically and clinically according to Crawford's criteria.

Relationship between meniscal tears and tibial slope on the tibial plateau.

Objective: The geometry of the tibial plateau has a direct influence on the translation and the screw home biomechanics of the tibiofemoral joint. Little information on the relationship between the tibial slope and meniscal lesions is available. The objective of this retrospective study was to examine the effect of the tibial slope on the medial and lateral meniscus lesions in patients with intact ACLs.

Treatment of Neer Type 2 fractures of the distal clavicle with coracoclavicular screw.

Objective: The aim of this study was to assess the outcome of coracoclavicular screw fixation in displaced distal clavicular fractures.

Methods: Sixteen patients with Neer Type 2 displaced distal clavicle fractures were treated with open reduction and internal fixation. Fixation was performed using a coracoclavicular screw with washer application.

Coracoclavicular ligament repair and screw fixation in acromioclavicular dislocations.

Objectives: We evaluated the long-term results of acromioclavicular dislocations treated with coracoclavicular fixation using a cancellous screw.

Methods: Coracoclavicular fixation was performed using the modified Bosworth technique in 32 patients (24 males, 8 females; mean age 35 years; range 19 to 58 years) with acromioclavicular dislocations. According to the Rockwood classification, seven patients had type III, nine patients had type IV, 13 patients had type V, and three patients had type VI dislocations.

Reconstruction of shoulder abduction and external rotation with latissimus dorsi and teres major transfer in obstetric brachial plexus palsy.

Objectives: We evaluated the results of latissimus dorsi and teres major tendon transfer to the rotator cuff together with musculotendinous lengthening of the subscapularis and/or pectoralis major muscles in patients with internal rotation contracture and decreased external rotation and abduction secondary to obstetrical brachial plexus palsy.

Methods: Thirty patients (18 boys, 12 girls; mean age 9 years; range 4 to 15 years) with internal rotation contracture and loss of external rotation and abduction of the shoulder secondary to obstetrical brachial plexus palsy underwent transfer of the latissimus dorsi/teres major tendons to the rotator cuff. In addition, musculotendinous lengthening of the subscapularis and pectoralis major (n=15), pectoralis major (n=9), and subscapularis (n=6) were performed.

The relationship between morphometric parameters and Trendelenburg sign following the Hardinge incision.

Objectives: We evaluated the relationship between morphometric parameters such as height, weight, and body mass index with the development of the Trendelenburg gait following the Hardinge approach, which is one of the most commonly used approaches in total hip arthroplasty.

Methods: The study included 59 patients (43 women, 16 men; mean age 55 years; range 37 to 74 years) who underwent total hip arthroplasty via the Hardinge approach for primary coxarthrosis. The patients were examined postoperatively at 15 days, and at the end of the first and third months.

Effects of calcitonin on the biomechanics, histopathology, and radiography of callus formation in rats.

Background: This study was designed to examine the effect of salmon calcitonin on fracture repair.

Methods: A transverse middiaphyseal fracture of the right tibia was surgically induced, and stabilized by an intramedullary Kirschner wire. Eighty male Wistar rats were arbitrarily assigned to four groups of 20 animals each.

Ponseti technique for the correction of idiopathic clubfeet presenting up to 1 year of age. A preliminary study in children with untreated or complex deformities.

Introduction: The aim of this study is to evaluate the effectiveness of the Ponseti method in children presenting before 1 year of age with either untreated or complex (initially treated unsuccessfully by other conservative methods) idiopathic clubfeet.

Patients And Methods: The authors report 134 feet of 92 patients with Dimeglio grade 2, 3, or 4 deformities treated with the Ponseti method. Twenty-four percent of feet were of complex deformities at initial presentation to the authors' clinics.

[The correlation between the accuracy of steroid injections and subsequent shoulder pain and function in subacromial impingement syndrome].

Methods: The study included 48 patients (29 women, 19 men; mean age 46.5 years; range 23 to 58 years) with subacromial impingement syndrome, whose complaints of shoulder pain lasted more than two months.
