INTRODUCTION: 3T MRI has become increasingly available for better imaging of interosseous ligaments, TFCC, and avascular necrosis compared with 1.5T MRI. This study assesses the sensitivity and specificity of 3T MRI compared with arthroscopy as the gold standard. PATIENTS AND METHODS: Eighteen patients were examined with 3T MRI using coronal T1-TSE; PD-FS; and coronal, sagittal, and axial contrast-enhanced T1-FFE-FS sequences. Two musculoskeletal radiologists evaluated the images independently...

PURPOSE: Various researchers have observed small areas of osteolysis after using bioabsorbable anchors in shoulder surgeries. The purpose of this study is to determine whether radiographic perianchor radiolucent rings after rotator cuff repair are associated with the failure of repair and also assess their clinical implications. Further, the most frequent location of the radiolucent rings in the double-row suture bridge configuration was also assessed. METHODS: One hundred and twenty-nine consecutive patients who underwent arthroscopic rotator cuff repair by suture bridge technique were retrospectively evaluated radiographically and clinically...

PURPOSE: The number of total hip and knee arthroplasties (THA and TKA) is steadily increasing. Many factors that influence pain have been reported, but little is known about the correlation between the time of day and the duration of surgery and postoperative pain. On one hand, surgical interventions are performed faster due to economic pressure; on the other hand, obtaining sound surgical skills and a thorough education are most important for young surgeons, particularly at university hospitals...

INTRODUCTION: The purpose of the study was to determine the surgical outcomes of intramedullary nailing in diaphyseal atypical femoral fractures (AFFs) and to evaluate the clinical outcomes of nail entry modification technique. MATERIALS AND METHODS: We retrospectively reviewed diaphyseal AFFs treated with IMN at nine institutions. In total, 82 patients were included. Surgical outcomes such as complication, union time, and femoral bowing were evaluated. We modified the nail entry of the straight nail from piriformis fossa to the tip of the greater trochanter in the bowed femur and compared the surgical outcomes between the original group and the modification group...

BACKGROUND: The use of fluoroscopy is necessary during proximal femoral fracture (PFF) osteosynthesis. The frequency of these procedures justifies a description of radiation exposure and comparisons between different techniques and between the different surgical team members. METHODS: This observational prospective and comparative study includes a series of 68 patients with PFF receiving osteosynthesis. Radiation exposure was assessed for all members of the operating team...

INTRODUCTION: Straight antegrade humeral nailing (SAHN) has become a standard technique for the surgical fixation of proximal humeral fractures, which predominantly affect elderly females. The nail's proximal anchoring point has been demonstrated to be critical to ensure reliable fixation in osteoporotic bone and to prevent iatrogenic damage to the superior rotator cuff bony insertion. Anatomical variations of the proximal humerus, however, may preclude satisfactory anchoring of the nail's proximal end and may bare the risk of rotator cuff violation, even though the nail is inserted as recommended...

PURPOSE: Whether racial differences are associated with function in the long term following surgical repair of lower extremity fractures has not been investigated. The purpose of this study is to compare how race affects function at 3, 6 and 12 months post-surgery following certain lower extremity fractures. METHODS: Four hundred and eighteen patients treated operatively for a lower extremity fracture (199 tibial plateau, 39 tibial shaft, and 180 rotational ankle fractures) were prospectively followed for 1 year...

INTRODUCTION: Up to date, there is a lack of reliable protocols that systematically evaluate the quality of reduction and hardware positioning of surgically treated calcaneal fractures. Based on international consensus, we previously introduced a 23-item scoring protocol evaluating the reduction and hardware positioning in these fractures based on postoperative computed tomography. The current study is a reliability analysis of the described scoring protocol. METHODS: Three raters independently and systematically evaluated anonymized postoperative CT scans of 102 surgically treated calcaneal fractures...

PURPOSE: To evaluate the outcomes of two commonly used transosseous-equivalent (TOE) arthroscopic rotator cuff repair (RCR) techniques for full-thickness supraspinatus tendon tears (FTST) using a robust multi-predictor model. METHODS: 155 shoulders in 151 patients (109 men, 42 women; mean age 59 ± 10 years) who underwent arthroscopic RCR of FTST, using either a knotted suture bridging (KSB) or a knotless tape bridging (KTB) TOE technique were included. ASES and SF-12 PCS scores assessed at a minimum of 2 years postoperatively were modeled using propensity score weighting in a multiple linear regression model...

INTRODUCTION: The value of routine radiographs during follow-up after distal radius fractures is unclear. The aim of this study was to evaluate whether routine radiographs performed during the follow-up period in patients with a distal radius fracture influenced clinical decision making. METHODS: This retrospective cohort study included patients aged ≥18 years who were treated for a distal radius fracture at four hospitals in The Netherlands in 2012. Demographic and clinical and radiographic characteristics were collected from medical records...

Adham Elgeidi, Abed El Negery, M Serry Abdellatif, Nabil El Moghazy
INTRODUCTION: Posterior comminution of the femoral neck fracture is a major cause of delayed and non-union owing to the loss of the buttressing effect against the posterior rotation. When a femoral neck fracture with posterior comminution is anatomically reduced, only the anterior portions of the femoral neck fracture surfaces are brought into contact leaving a posterior defect. The purpose of this study was to evaluate the use of fibular strut grafting and dynamic hip screw (DHS) for fresh femoral neck fractures with posterior comminution in young patient less than 50 years...

Cephalomedullary fixations are commonly used in the treatment of intertrochanteric fractures. In clinical practice, one of the difficulties is when we exit the guide wire in a wrong position of femoral neck and insert near the hole again, the guide wire often flow into the previous track. This study develops a surgical technique to direct the guide wire to slip away the previous track and slip into a right position. When guide wire is exited to the cortex of femoral, we let the wire in and out at the cortical layer for several times to enlarge the entry hole...

AIM: Secondary femur fracture subsequent to treatment of trochanteric fractures with cephalomedullary nailing (i.e., a periprosthetic fracture related to the cephalomedullary nail) is a rare but very severe complication. As such, the aim of this study was to assess the impact of revision surgery and general state of health on mortality and functional outcomes in patients suffering femur fractures following treatment with cephalomedullary nails. MATERIALS AND METHODS: Between 2000 and 2015, 3549 patients presenting with OTA/AO 31A1-3 femur fractures were admitted to our department and subsequently treated with either a Gamma(®) Nail or PFNA(®)...

INTRODUCTION: Although it is well known from cadaveric and biomechanical studies that transtibial femoral tunnel (TT) positioning techniques are associated with non-anatomic tunnel positions, controversial data exist as so far no clinical differences could have been found, comparing transtibial with anteromedial techniques (AM). The purpose of the study was to analyze if graft failure following TT ACL reconstruction was more commonly associated with non-anatomic tunnel position in comparison with the AM technique...
