Randomized Controlled Trial Comparative StudyThe effects of corticosteroid injection versus local anesthetic injection in the treatment of lateral epicondylitis: a randomized single-blinded clinical trial.
This study seeks to compare two treatment methods of lateral epicondylitis: corticosteroid injection (CSI) and a local anesthetic injection (LAI). ⋯ For lateral epicondylitis, CSI has the best short-term treatment results yet the highest recurrent rates. The combination of CSI with other treatment option or with a change in injection technique from single injection to peppering injection may be promising.

Comparative StudyJoint line changes in cruciate-retaining versus posterior-stabilized computer-navigated total knee arthroplasty.
This study compared joint line changes and functional outcomes between cruciate-retaining (CR) and posterior-stabilized (PS) computer-navigated total knee arthroplasties (TKAs). With the increased precision offered by computer navigation, we hypothesized that there should be minimal differences in the joint line changes between the groups and thus no significant differences in the clinical outcomes. ⋯ III.

Randomized Controlled Trial Comparative StudyNo difference in mortality between cemented and uncemented hemiprosthesis for elderly patients with cervical hip fracture. A prospective randomized study on 334 patients over 75 years.
Laboratory and human mechanical studies indicated that chemical substances in bone cement had toxic and prothrombotic effects. Impaction of cement added a mechanical trauma to the reaming and broaching procedure and contributed to a substantial local and systemic thrombin generation. Case reports and materials have indicated bone cement as the immediate trigger of cardiorespiratory and vascular dysfunction, occasionally fatal, and described as the bone cement implantation syndrome. In spite of this knowledge, bone cement has gained popularity and is widely used for prosthesis fixation, possibly due to a lack of clinical evidence supporting the basic science indicating bone cement as a mortality risk factor. ⋯ Installation of non-cemented hemiprostheses in elderly with hip fracture may have benefits perioperatively regarding operation time and bleeding, and do not seem to influence 1 year mortality relative to cemented implants.

Anterior surgical options for the treatment of cervical spondylotic myelopathy in a long-term follow-up study.
To provide a basis for the choice of anterior surgery procedures in the treatment of cervical spondylotic myelopathy (CSM) through long-term follow-up. ⋯ For CSM with compression coming from the front side, proper anterior decompression based on the specific conditions could directly eliminate the compression. Through long-term follow-up, the effect of decompression became observable.

Comparative StudyPosterior interosseus nerve vs. medial cutaneous nerve of the forearm: differences in digital nerve reconstruction.
Digital nerve defects are common in hand trauma and for primary or secondary nerve reconstruction, the autologous nerve graft remains the gold standard. This study compares the regeneration results and donor side morbidity of either the posterior interosseus nerve (PIN) graft or the medial antebrachial cutaneous nerve (MACN) graft. 16 patients (group A, age 43 ± 13 years) with digital nerve defects were treated with a PIN graft and 12 patients (group B, age 40 ± 15 years) received a MACN graft. The average nerve gap was 22 mm in each group. ⋯ Regarding the donor side morbidity, almost all patients complained about a disturbing scar formation and unpleasant paresthesia at the forearm down to the rascetta. Neuroma-associated pain has been detected in 4 cases. Although there has been no significant difference in terms of nerve regeneration, we recommend the use of the PIN graft for digital nerve reconstruction, since harvesting this nerve is fast and easy and without any donor side morbidity compared to the MACN graft.
