Comparative Study Clinical Trial
Unipolar versus bipolar Exeter hip hemiarthroplasty: a prospective cohort study on 830 consecutive hips in patients with femoral neck fractures.
Hip replacement using a hemiarthroplasty (HA) is a common surgical procedure in elderly patients with fractures of the femoral neck. Data from the Swedish Hip Arthroplasty Register suggest that there is a higher risk for revision surgery with the bipolar HA compared with the unipolar HA. ⋯ The prosthetic design (uni- or bipolar) had no influence on the risk for reoperation or dislocation, nor had the age, gender or the surgeon's experience. The secondary HAs were associated with a significantly increased risk for reoperation (HR 2.6, CI 1.5-4.5) or dislocation (HR 3.3, CI 1.4-7.3) compared to the primary HAs. We found no difference in the risk for reoperation or dislocation when comparing Exeter unipolar and bipolar HAs, but special attention is called for to reduce the risk of prosthesis dislocation and reoperation after a secondary HA.

Claviculectomy is a rare and poorly described event in the surgical therapy of diseases of the clavicle. We present a case series and functional results of patients who underwent total claviculectomy. ⋯ The surgical technique described for total claviculectomy, along with the insertion of local antibiotic beads, was able to eliminate infection in every case. Good functional results and a low complication rates were observed. For good functional results and the permanent elimination of infection, adjacent joints have to be addressed, the periosteal tube should be preserved and early functional treatment is essential.

Revision internal fixation for femoral-neck nonunion is a challenging procedure. Treatment options are osteotomy, osteosynthesis using various implants and grafting techniques (muscle pedicle, vascularised or nonvascularised fibular graft) or arthroplasty. The objective of this article is to report the outcome of revision internal fixation using an angle blade plate and autogenous fibular graft in symptomatic aseptic femoral-neck nonunion. ⋯ Angle blade plate provides rigid stability and offloads any shearing force over the fibular graft when used for revision internal fixation in aseptic femoral-neck nonunion. Thus, the fibular graft only serves the purpose of osteogenesis and stimulates the surrounding host cells to promote healing at the nonunion site. We recommend the angle blade plate and autogenous fibular graft as a viable option for hip-joint salvage in revision internal fixation of aseptic femoral-neck nonunion.

We evaluated the usefulness of percutaneous reduction and leverage fixation using K-wires in children with radial neck fractures. ⋯ Percutaneous reduction and leverage fixation using K-wires in children with radial neck fractures is a recommended surgical treatment that can achieve recovery of normal radial angulation and elbow motion.

To investigate the correction effectiveness, incidence rate of distal adding on, and post-operative spinal balance in Lenke 3C and 6C AIS treated with extensive fusion using posterior pedicle screw-only constructs. ⋯ In Lenke 3C and 6C scoliosis, extensive fusion can produce satisfactory corrections from the perspectives of both Cobb angle and vertebral translation and rarely causes significant distal adding-on, global imbalance or trunk shift.
