Distal biceps tendon ruptures present with an initial tearing sensation accompanied by acute pain; weakness may follow. The hook test is very reliable for diagnosing ruptures, and magnetic resonance imaging can provide information about the integrity and any intrasubstance degeneration of the tendon. There are subtle differences between the outcomes of single and modified two-incision operative repairs. ⋯ Fixation techniques include the use of bone tunnels, suture anchors, interference screws, and cortical fixation buttons. There is no clinical evidence supporting the use of one fixation method over another, although cortical button fixation has been shown to provide the highest load tolerance and stiffness. Postoperative rehabilitation has become more aggressive as fixation methods have improved.

Clamp-assisted reduction of high subtrochanteric fractures of the femur: surgical technique.
Subtrochanteric fractures can be a treatment challenge. The substantial forces that this region experiences and the fact that the proximal fragment is frequently displaced make accurate reduction and internal fixation difficult. The purpose of this study was to evaluate a series of patients who had undergone clamp-assisted reduction and intramedullary nail fixation to determine the impact of this technique on fracture union rates and reduction quality. ⋯ Surgical treatment of subtrochanteric femoral fractures with clamp-assisted reduction and intramedullary nail fixation techniques with judicious use of a cerclage cable can result in excellent reductions and a high union rate. Careful attention to detail is important to perform these maneuvers with minimal additional soft-tissue disruption.

Perioperative stroke after total joint arthroplasty: prevalence, predictors, and outcome.
The risk of perioperative stroke following cardiac and carotid artery surgery is well documented. There is an apparent lack of recognition and appreciation of this complication after total joint arthroplasty. The present study was designed to determine the prevalence of, and outcome after, perioperative stroke following total joint arthroplasty. In addition, risk factors for the development of this complication were evaluated in an attempt to identify a strategy that could minimize the prevalence of this complication. ⋯ Perioperative stroke is a rare but potentially devastating complication of total joint arthroplasty, with a high rate of morbidity and mortality. Vigilant attention to prevent, detect, and treat this complication in a timely manner may alter the course of the disease.

Total hip arthroplasty with shortening subtrochanteric osteotomy in Crowe type-IV developmental dysplasia: surgical technique.
When surgeons perform total hip arthroplasty for hips with a high dislocation related to developmental dysplasia of the hip, obtaining long-term stable implant fixation and optimizing patient function remain challenges. The purpose of this paper was to evaluate the results of cementless arthroplasty with a simultaneous subtrochanteric shortening osteotomy in a group of patients with Crowe type-IV developmental dysplasia of the hip. ⋯ Cementless total hip arthroplasty combined with a subtrochanteric femoral shortening osteotomy in patients with a high hip dislocation secondary to developmental dysplasia was associated with high rates of successful fixation of the implants and healing of the osteotomy site and a mean postoperative Harris hip score of 89 points. The complication rate, however, was substantially higher than that associated with primary total hip arthroplasty in patients with degenerative arthritis.

Intermediate to long-term results following the bernese periacetabular osteotomy and predictors of clinical outcome: surgical technique.
The Bernese periacetabular osteotomy is a commonly used non-arthroplasty option to treat developmental hip dysplasia in symptomatic younger patients. Predicting which hips will remain preserved and which hips will go on to require arthroplasty following periacetabular osteotomy is a major challenge. In the present study, we assessed the intermediate to long-term results following periacetabular osteotomy to demonstrate the clinical outcomes for patients with varying amounts of dysplasia and arthritis. From these results, a probability-of-failure analysis was conducted to predict the likelihood of hip preservation and to improve surgical decision-making. ⋯ The Bernese periacetabular osteotomy can be effective for the treatment of painful hip dysplasia, but complications may be expected in as many as 15% of cases. The ideal candidate is the patient who is less than thirty-five years of age and who has good or excellent hip joint congruency.
