Glenoid bone loss and Hill-Sachs width percentage score are useful to select optimal operation for the treatment of glenohumeral instability in overhead athletes: Arthroscopic Bankart repair with remplissage versus open Latarjet.

Purpose: Glenohumeral instability with combined bone lesion in contact and overhead athletes with subcritical bone loss is challenging to treat with high recurrent instability. Treatment options are arthroscopic Bankart repair with remplissage and Latarjet operations. However, there is no consensus on their effectiveness.

Effect of suprascapular nerve injury on rotator cuff enthesis.

Background: Numerous reports have shown that retracted rotator cuff tears may cause suprascapular nerve injury, and nerve injury causes atrophy and fat accumulation in the rotator cuff muscles. However, the effect of suprascapular nerve injury on rotator cuff enthesis has not been directly defined. This study aimed to investigate the effect of suprascapular nerve injury on rotator cuff enthesis.

Completion repair exhibits increased healing characteristics compared with in situ repair of partial thickness bursal rotator cuff tears.

Purpose: Little information is available regarding the healing capacity of in situ and completion repair for the treatment of partial thickness rotator cuff tears. The purpose of the study was to analyze the healing characteristics of both techniques.

Methods: Twenty-four adult Sprague-Dawley rats were operated.

Complications during removal of stainless steel versus titanium nails used for intramedullary nailing of diaphyseal fractures of the tibia.

Objectives: Intramedullary nailing is the treatment of choice for fractures of the tibial shaft, which might necessitate the nail removal due to complications in the long-term. Although considered as a low-risk procedure, intramedullary nail removal is also associated with certain complications. Here, we compared the most commonly used stainless steel and titanium nails with respect to the complications during removal and clinical outcome for intramedullary nailing of diaphyseal fractures of the tibia.

Low pH irrigation fluids have positive effect on intra-articular chondral healing.

Purpose: The aim of this study was to evaluate the effect of Ringer's lactate (RL) solutions with different pH values on early histologic healing in a microfracture model in vivo. The null hypothesis of the presented study is that irrigation fluids with lower pH (6.4) have negative effects on fibrous cartilage healing.

Palmaris longus tendon graft versus modified Weaver-Dunn procedure via dynamic button system for acromioclavicular joint reconstruction in chronic cases.

Background: The hypothesis of this clinical study was that coracoclavicular (CC) reconstruction using autogenic palmaris longus graft through the GraftRope (PLG) system (Arthrex, Inc., Naples, FL, USA) would provide superior clinical and radiologic results compared with modified Weaver-Dunn procedure with the dynamic TightRope (Arthrex, Inc.) system (WDT).

The effect of femoral nerve block on fracture healing via expressions of growth factors and β-catenin.

Introduction: Many patients of all ages are admitted to hospital due to bone fractures. The etiology of fracture has a very wide spectrum, ranging from motor accidents to pathological conditions such as tumors, osteoporosis, and others. Bone fracture healing is a well-programmed and well-organized process, but is also long and intractable.

Comparative study of the closed reduction percutaneous cannulated screw fixation and open reduction palmar locking plate fixation in the treatment of AO type A2 distal radius fractures.

Introduction: The present study was designed to demonstrate the efficacy of standard 4.0 mm cannulated screw fixation by comparing it with palmar locking plate fixation in the treatment of acute, unstable, simple extra-articular distal radius fractures.

Materials And Methods: We prospectively collected and retrospectively analyzed outcomes data for 65 patients aged between 18 and 60 with AO type A2 fractures treated with closed reduction, percutaneous cannulated screw fixation (CRPCS n = 34) or open reduction palmar locking plate fixation (ORPLP n = 31).

Blocking screws for the treatment of distal femur fractures.

Intramedullary nailing is one of the most convenient biological options for treating distal femoral fractures. Because the distal medulla of the femur is wider than the middle diaphysis and intramedullary nails cannot completely fill the intramedullary canal, intramedullary nailing of distal femoral fractures can be difficult when trying to obtain adequate reduction. Some different methods exist for achieving reduction.

Percutaneous cannulated screw fixation in the treatment of distal radius fractures.

Purpose: The aim of this study was to determine the results of closed reduction and percutaneous fixation of distal radial fractures with standard 4.0-mm cannulated screw.

Methods: We collected prospective outcomes data for 20 patients between 18 and 60 years of age (mean 39) with acute, displaced, extraarticular and unstable fractures of the distal radius treated with closed reduction, percutaneous cannulated screw fixation and early mobilization.

Comparison of palmar locking plate and K-wire augmented external fixation for intra-articular and comminuted distal radius fractures.

Objectives: This study was designed to compare the results of palmar locking plate and K-wire augmented external fixation in the treatment of intra-articular comminuted distal radius fractures.
