Comparison of standard screw fixation versus suture button fixation in Lisfranc ligament injuries.

Background: The standard operative treatment for Lisfranc injuries is to openly reduce them and use screw fixation. Due to the current trend of applying a more physiologic fixation and decreasing the need for screw removal, a recent interest has developed in suture-button fixation. The purpose of this study was to compare the suture button technique for Lisfranc fracture fixation to the traditional interfragmentary screw fixation.

Safety of ankle trans-syndesmotic fixation.

Background: Ankle syndesmosis fixation is often employed with the utilization of many variable methods and implants. Complications secondary to trans-syndesmotic fixation have been described, yet the proximity of a single trans-syndesmotic screw to the perforating branch of the peroneal artery (PBPA) has not.

Materials And Methods: Sixteen cadaveric legs received a single trans-syndesmotic screw using standard AO technique.

The complicated Jones fracture, including revision and malalignment.

Using radiographs culled over a 33-month period, the treatment, complications, revision, and rehabilitation of complicated Jones fractures and stress fractures involving the proximal diaphysis are examined. Although the non-operative approach remains viable, the exigencies and desires of the athletic and leg-based working population require sooner-rather-than-later return to play or work. Fortunately, these needs can be matched by the available and functioning orthopedic practice of intramedullary screw fixation.

Sulfonamido-aryl ethers as bradykinin B1 receptor antagonists.

The synthesis and identification of sulfonamido-aryl ethers as potent bradykinin B1 receptor antagonists from a approximately 60,000 member encoded combinatorial library are reported. Two distinct series of compounds exhibiting different structure-activity relationships were identified in a bradykinin B1 whole-cell receptor-binding assay. Specific examples exhibit K(i) values of approximately 10nM.

Comparison of a continuous temperature-controlled cryotherapy device to a simple icing regimen following outpatient knee arthroscopy.

This prospective, randomized study compared postoperative pain control with use of a continuous temperature-controlled cryotherapy system versus a traditional ice therapy regimen following outpatient knee arthroscopy. Patients with unilateral knee pathology scheduled for outpatient arthroscopic surgery were included. Patients with major ligament reconstructions were excluded.

Endoscopic bony and soft-tissue decompression of the retrocalcaneal space for the treatment of Haglund deformity and retrocalcaneal bursitis.

Background: The traditional operative management of Haglund deformity and retrocalcaneal bursitis consists of an open excision of the inflamed bursa, resection of the posterosuperior calcaneal tuberosity, and debridement of the Achilles tendinopathy. In an effort to reduce morbidity and recovery time, an endoscopic technique was used for the management of this condition.

Methods: Thirty consecutive patients (32 heels) who had retrocalcaneal bursitis unrelieved by nonoperative measures were treated with the endoscopic technique.

The hallucal sesamoid complex.

The hallucal sesamoids are vitally important to normal weight bearing and foot mechanics. The sesamoid complex of the hallux normally transmits up to 50% of body weight and during push-off can transmit loads >300%. These high stresses may lead to both acute and chronic pathologies of the hallucal sesamoids.

Identification and biological characterization of 6-aryl-7-isopropylquinazolinones as novel TRPV1 antagonists that are effective in models of chronic pain.

Vanilloid receptor 1 (VR1, TRPV1) is a cation-selective ion channel that is expressed on primary afferent neurons and is upregulated following inflammation and nerve damage. Blockers of this channel may have utility in the treatment of chronic nociceptive and neuropathic pain. Here, we describe the optimization from a high throughput screening hit, of a series of 6-aryl-7-isopropylquinazolinones that are TRPV1 antagonists in vitro.

Repeat patellar tendon rupture in a child.

In summary, we present the first published case of a patellar tendon midsubstance rupture in an otherwise healthy 9-year-old with repeat rupture at age 10.

Can using emergent technology incur liability?

There are numerous areas of potential liability for the practicing surgeon attempting to upgrade skills and introduce emergent technology into his or her practice. The College understands that graduate medical education in a teaching institution, continuing medical education at our College-sponsored venues, and all other sponsored or co-sponsored educational activities each carry risks and benefits. Current College activities are directed toward enhancing translation of emergent surgical technology into clinical practice as effectively, productively, safely, and as free of risk as possible.

A joint protocol for home skeletal traction.

Cost-effective delivery of quality patient care is a major focus of the orthopaedic advanced practice nurse's practice. Long-term skeletal traction therapy for select fractures of the pelvis remains a treatment option for certain patients. The purposes of this article are to describe the development of a joint proposal for home skeletal traction therapy and to analyze the cost savings involved by reviewing a case study of a home traction patient.

Autogenous bone grafting of hallux sesamoid nonunions.

We first performed autogenous bone grafting for lesions of the hallux sesamoid in 1984. During the next 9 years, 21 patients (11 men and 10 women with an average age of 34 and 32 years, respectively) underwent this surgical procedure for symptomatic tibial hallux sesamoid non-unions. Successful bony union was achieved in all but two patients.

Syndesmotic screw placement: a biomechanical analysis.

At the present time, syndesmotic screw fixation is recommended when there is a tibiofibular diastasis, a Maisonneuve fracture, or syndesmotic instability after fixation of distal tibia-fibula fractures. The aim/purpose of this study was to demonstrate the optimal level of syndesmotic screw placement before creation of a Maisonneuve fracture. Legs of 17 embalmed cadavers underwent knee disarticulation.

Ultrasonography in the management of painful hips in children.

The decision to aspirate a painful hip joint is often based on history, physical, and laboratory findings. The purpose of this study is to determine whether ultrasound is helpful in making decisions to aspirate a painful hip joint in children. The anterior capsular distance was determined in 10 children with painful or irritable hips.

Posterior ankle impingement.

Thirty cases of posterior ankle impingement in 28 patients were treated over a 10-year period (1982-1992). All conditions were caused by forced plantar flexion. An os trigonum or posterior process fracture was demonstrated radiographically in 63% of these cases, and an intact posterior process was demonstrated in 33%.
