Randomized Controlled TrialReactionary haemorrhage reduction with adrenaline infiltration in proximal tibial osteotomy: a randomized clinical study of safety and efficacy.
In corrective osteotomy, wound closure is undertaken with or without deflation of the tourniquet. Hypoxia from the tourniquet causes vasodilatation associated with reactionary haemorrhage and reduced haemoglobin concentration and possibly increased blood transfusion rate. Reactionary haemorrhage and related transfusion need can be reduced through vasoconstriction from adrenaline infiltration. ⋯ In conclusion, wound infiltration with adrenaline was effective in reducing the extent of reactionary haemorrhage and post-operative drop in haemoglobin concentration. There was no significant difference in the transfusion rates in both groups.

Comparative Study Clinical TrialCushion bearings versus large diameter head metal-on-metal bearings in total hip arthroplasty: a short-term metal ion study.
Metal-on-metal total hip arthroplasty (MOM THA) has the advantage of replicating the femoral head size, but the postoperative elevation of serum metal ion levels is a cause for concern. Metal-on-polycarbonate-urethane is a new cushion bearing featuring a large diameter metal head coupled with a polycarbonate-urethane liner. ⋯ These findings warrant the continued clinical study of compliant bearing options.

Clinical TrialDisplaced femoral neck fractures in the young: significance of posterior comminution and raised intracapsular pressure.
Osteosynthesis in fracture neck of femur (NOF) in young is a universally acceptable procedure. Various factors affect the outcome; with AVN (avascular necrosis) and non-union primarily contributing to adverse results in such patients. To identify factors affecting outcome of displaced fracture NOF, a prospective cohort study was carried out in the setting of a tertiary care centre in developing country. ⋯ Prognosis of displaced fracture NOF is significantly associated significant with posterior comminution and intracapsular pressure difference between fractured and normal side.

Clinical TrialCombined tears of the subscapularis and supraspinatus tendon: clinical outcome, rotator cuff strength and structural integrity following open repair.
Anterosuperior rotator cuff tears involving the subscapularis and supraspinatus tendons are less common than other tears of the rotator cuff. The purpose of this study was to report the clinical outcome, rotator cuff strength and structural integrity of open repair of combined anterosuperior rotator cuff tears. ⋯ Open repair of combined anterosuperior rotator cuff tears achieved good postoperative results despite a residual rotator cuff strength deficit. Combined supraspinatus-/full-thickness subscapularis tears achieved equal clinical and radiographic results compared with supraspinatus-/partial-thickness subscapularis tears.

Comparative StudyA novel computer-assisted drill guide template for thoracic pedicle screw placement: a cadaveric study.
The objective of this study was to develop a novel, patient-specific, navigational template for thoracic pedicle screw placement. ⋯ We have developed a novel, patient-specific, navigational template for thoracic pedicle screw placement with good applicability and high accuracy.
