Risk factors leading to total hip arthroplasty in patients with subchondral insufficiency fractures of the femoral head.
To retrospectively evaluate factors leading to total hip arthroplasty (THA) in patients with subchondral insufficiency fractures (SIF) of the femoral head. METHODS. 5 men and 22 women aged 51 to 85 (mean, 72) years with SIF of the femoral head initially underwent conservative treatment. THA was later performed for 13 patients, as the hip pain became worse secondary to joint space narrowing and/ or femoral head collapse. Patient demographics and radiological variables were retrieved. Risk factors leading to THA in patients with SIF of the femoral head were identified. Receiver operating characteristic curves were used to determine optimal cut-off values for the significant risk factors. ⋯ Elderly patients with SIF of the femoral head are at higher risk of undergoing THA.

To evaluate the characteristics of bicyclespoke injuries in a suburban Indian population. ⋯ Bicycle-spoke injuries usually affected the ankle region, and the wound was usually deeper than it appeared on initial examination. Reassessment of the wound after 48 hours is recommended. Severity of soft-tissue injury was the determinant of overall function; bone fractures by themselves did not alter the duration of recovery. To prevent bicyclespoke injuries, spoke guards and foot rests should be used, and children being carried on a bicycle should wear proper shoes. Education on injury mechanism, severity, and preventive measures is also important.

Case ReportsSpinal nerve root herniation into a pseudomeningocele associated with lumbar spondylolysis: a case report.
A 38-year-old man presented with low back pain and sciatica on the left side. Magnetic resonance imaging showed spinal nerve root herniation into a pseudomeningocele associated with lumbar spondylolysis. After closure of the dural defect, the sciatic pain was relieved and subsequently the patient was able to return to work.

Randomized Controlled Trial Comparative StudyContinuous infiltration of local anaesthetic following total knee arthroplasty.
To determine whether continuous infiltration of local anaesthetic can reduce the pain score and morphine use over 48 hours after total knee arthroplasty (TKA). ⋯ Continuous infiltration of local anaesthetic into the intra-articular space and subcutaneous tissues, in addition to PCA with intravenous morphine, provides significantly more pain relief and reduces morphine use.
