Orthopedic Surgeons' Management of Elective Surgery for Patients Who Use Nicotine.

Despite significant research documenting the detrimental effects of tobacco, the orthopedic literature lacks evidence regarding how surgeons alter their management of elective surgery when patients use nicotine. To better understand how patients' use of nicotine influences orthopedic surgeons' pre- and postoperative management of elective surgery, a 9-question paper survey was distributed at the 2012 annual meeting of the American Academy of Orthopaedic Surgeons among attending US orthopedic surgeons, including general orthopedists and specialty-trained orthopedic surgeons. Survey questions focused on attitudes and practice management regarding patients who use nicotine. Using a chi-square test, no statistically significant variation was observed between subspecialists and general orthopedists or among different subspecialties. Ninety-eight percent of the orthopedic surgeons surveyed counseled tobacco users about the adverse effects of nicotine. However, approximately half of all of the respondents spent less than 5 minutes on perioperative nicotine counseling. Forty-one percent of all of the respondents never delayed elective surgery because of a patient's nicotine use, followed closely by 39% delaying surgery for less than 3 months. Subspecialty had little influence on how orthopedic surgeons managed nicotine users. The high rate of counseling on the adverse effects of nicotine suggested agreement regarding the detrimental effects of smoking. However, the study population infrequently delayed surgery or used smoking cessation measures. Studies are needed to determine why few surgeons frequently alter the management of nicotine users and what modifications in orthopedic practice could improve outcomes for these patients.

Rigid internal fixation of displaced distal radius fractures.

Distal radius fractures, the most common long bone fracture, are treated in several ways, including closed reduction, percutaneous pinning, external fixation, and open reduction and internal fixation. This article presents a surgical technique and a series of patients treated with a novel minimally invasive intramedullary fixation technique. The implant is a partially flexible intramedullary rod that can be locked in a rigid position once it is implanted in the bone. An awl and reamer are passed through a starter hole in the radial styloid using a 2-cm incision between the 1st and 2nd dorsal compartments. The device is then implanted under the articular surface, and the distal end of the curved implant is placed down the intramedullary canal of the radius. After locking the shaft segment rigidly, screws are placed through the implant under the distal radial articular margin to stabilize the fracture site. The sensory branches of the radial nerve are retracted during the case. Patients are treated in a wrist splint for a short period of time (2 to 4 weeks) depending on fracture type. The case examples demonstrate the minimally invasive nature of this procedure, the surgical technique, methods of fracture reduction and implantation, and surgical outcomes. Radiographic outcomes, postoperative motion, postoperative function, and validated outcome measures are demonstrated. This minimally invasive technique is ideally suited for distal radial fractures that do not involve the articular surface. It is a safe and effective technique that can provide excellent results.

Finite element analysis and physiologic testing of a novel, inset glenoid fixation technique.

The success of shoulder arthroplasty surgery has been limited by a common complication: glenoid implant loosening. Eccentric loading of the glenoid due to migration of the humeral head is considered to be the major cause of glenoid loosening and is referred to as the rocking-horse phenomenon. Glenoid implant loosening may cause pain, limitation of function, and the need for complicated revision surgery. Our hypothesis was that an inset fixation technique could offer increased fixation strength and minimize the effects of the rocking-horse phenomenon on glenoid loosening.

Total shoulder replacement surgery with custom glenoid implants for severe bone deficiency.

Treatment of patients with shoulder arthritis and severe glenoid bone loss is controversial. Medial and posterior bone loss limits the size of the glenoid vault, which is the structural support of all current glenoid designs. This study presents short-term outcomes of a treatment using inset glenoid implants during shoulder replacement surgery in deficient glenoid bone.
