Decreased postoperative gluteus medius muscle cross-sectional area measured by computed tomography scan in patients with intertrochanteric fractures nailing.
In patients with femoral intertrochanteric fractures treated by cephalomedullary (CM) nailing, abduction force reportedly decreased by 25-30% during the postoperative follow-up period. The purpose of the current study is to evaluate the cross-sectional area (CSA) and adipose tissue ratio (ATR) of the gluteus medius muscle on the postoperative computed tomography (CT) view, expecting this graphic study will support clinical results. ⋯ Our image findings documented that gluteus medius is significantly changed in CSA and ATR. The damage possibly triggers decrease in muscular strength of hip abduction in the postoperative follow-up period. This measurement is objective, and needed no patient's endurance and cooperation.

Comparative StudyInvestigation of efficacy of treatment in spinal cord injury: Erythropoietin versus methylprednisolone.
Investigation of the expression of platelet-derived growth factor (PDGF)-β and glial fibrillary acidic protein (GFAP) in rats with spinal cord injury as a marker of neurologic recovery between groups treated with erythropoietin (EPO) and methylprednisolone (MP). ⋯ EPO seems to better increase the expression of PDGF-β, thus produce better results in locomotor functions when compared to MP.

Randomized Controlled TrialEffect of intraoperative autologous transfusion techniques on perioperative hemoglobin level in idiopathic scoliosis patients undergoing posterior spinal fusion: A prospective randomized trial.
Massive blood loss during posterior spinal fusion for adolescent idiopathic scoliosis remains a significant risk for patients. There is no consensus on the benefit of acute normovolemic hemodilution (ANH) or intraoperative cell salvage (ICS) in scoliosis surgery. ⋯ The addition of ANH to ICS in posterior spinal fusion surgery for AIS resulted in a similar decrease in hemoglobin levels between preoperative values and at 24 h postoperatively.

Prospective study of surgical fixation of radial head fractures using cannulated headless compression screws for simple and complex radial head fractures.
Fixing the two-part Mason II radial head fracture using screws is becoming a popular practice. However, the screw fixation efficacy for three-part Mason III and IV fractures is controversial. The purpose of this study is to determine the effectiveness of using a uniform technique of headless compression screw fixation in simple, isolated Mason II and complex three-part Mason III and IV radial head fractures in terms of functional outcome, treatment efficiency and assessment of complications with the procedure. ⋯ Overall clinical and functional outcomes of this technique are satisfactory in both simple and complex fracture groups, with simple Mason II fracture group doing better than the complex three-part Mason III and IV fractures in terms of Mayo Elbow Score and range of motion. Screw fixation has the advantage of less periosteal stripping and less impingement compared to other fixation methods and also allows for flexible fixation in constrained areas. Headless compression screw fixation can be considered as a method of fracture fixation for both simple and complex three-part radial head fractures.

Analysis of functional outcome of Hoffa fractures: A retrospective review of 32 patients.
Hoffa fractures are uncommon intra-articular fractures of femoral condyle in coronal plane. The purpose of our study is to assess radiologic and functional outcome in operatively treated Hoffa fractures. ⋯ Operative treatment of Hoffa fractures yields fairly good functional outcome. One must endeavor to achieve adequate intraoperative exposure and stable congruous articular reconstruction. Early aggressive physical therapy is a harbinger of optimal outcome.
