Volar plate fixation of recalcitrant scaphoid nonunions with volar carpal artery vascularized bone graft

Chronic scaphoid fracture nonunion continues to present a significant challenge to the treating orthopedic surgeon. Internal fixation with threaded compression screws leads to high union rates, and is currently the gold standard, but there are certainly circumstances where a scaphoid screw does not provide the stability necessary for nonunion repair. Results using a volar buttress plate have been promising, but have not been described in conjunction with the use of vascularized bone graft. Vascularized bone grafts have been shown to be highly effective in achieving rapid and reproducible rates of union. We describe a novel combination of a vascularized volar distal radius wedge autograft pedicled on the volar carpal artery and volar buttress plating for salvage treatment of chronic scaphoid nonunion.

Scaphoid Plate Fixation and Volar Carpal Artery Vascularized Bone Graft for Recalcitrant Scaphoid Nonunions

PURPOSE We sought to evaluate the clinical and radiographic outcomes after treatment of symptomatic, recalcitrant scaphoid nonunions using a novel combination of volar scaphoid buttress plating with a pedicled vascularized bone graft. METHODS We retrospectively followed 9 patients with recalcitrant scaphoid waist nonunions, characterized by failed prior surgery, long duration of nonunion, avascular necrosis of the proximal pole, or considerable bone loss at the nonunion site. We treated these persistent nonunions through a single volar incision with a pedicled vascularized bone graft, based on the volar carpal artery, and a 1.5-mm precontoured, scaphoid-specific, volar buttress plate. Postoperatively, we assessed objective and subjective outcomes as well as radiographs and computed tomography scans. RESULTS The median duration of nonunion was 15 months, ranging from 6 to 96 months. Postoperative follow-up ranged from 11 to 19 months. Computed tomography scans demonstrated union in 8 of 9 cases. Complications included 1 minor hematoma that spontaneously resolved. One scaphoid failed to unite, requiring revision surgery. Three patients experienced problems with the plate. One plate was removed from a patient who noted persistent clicking, and 2 plates have caused symptomatic clicking, likely requiring future removal. Eight of nine patients reported satisfaction with the procedure, with QuickDash scores averaging 8.2. CONCLUSIONS We present a series of recalcitrant scaphoid nonunions treated with a novel technique of volar buttress plating and vascularized bone graft. In this series, we found a high rate of union, with consistent radiographic improvement and symptomatic relief. This procedure can be performed using a single incision and with minimal donor site morbidity. Volar plating of a scaphoid nonunion comes with the risk of articular prominence, but offers a new alternative to headless screw fixation. Our early results from this series are promising and support this protocol as a viable alternative for challenging nonunions. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic IV.

Total Wrist Arthroplasty

Total wrist arthroplasty using current design implants has evolved into a fairly predictable procedure for rheumatoid, osteoarthritic, and posttraumatic patients. Although complications can occur, the incidence of these has dropped over the past decade with implant design modifications. The article summarizes the current use of total wrist arthroplasty and touches on issues of revision surgery, secondary fusion, complications, wrist fusion takedown, and radiolucency around implants. Technical tips are also provided for both primary and revision surgery.

Impact of laboratory cost display on resident attitudes and knowledge about costs

Aim Cost awareness has been proposed as a strategy for curbing the continued rise of healthcare costs. However, most physicians are unaware of the cost of diagnostic tests, and interventions have had mixed results. We sought to assess resident physician cost awareness following sustained visual display of costs into electronic health record (EHR) order entry screens. Study Design We completed a preintervention and postintervention web-based survey. Participants were physicians in internal medicine, paediatrics, combined medicine and paediatrics, obstetrics and gynaecology, emergency medicine, and orthopaedic surgery at one tertiary co are academic medical centre. Costs were displayed in the EHR for 1032 unique laboratory orders. We measured attitudes towards costs and estimates of Medicare reimbursement rates for 11 common laboratory and imaging tests. Results We received 209 survey responses during the preintervention period (response rate 71.1%) and 194 responses during the postintervention period (response rate 66.0%). The proportion of residents that agreed/strongly agreed that they knew the costs of tests they ordered increased after the cost display (8.6% vs 38.2%; p<0.001). Cost estimation accuracy among residents increased after the cost display from 24.0% to 52.4% for laboratory orders (p<0.001) and from 37.7% to 49.6% for imaging orders (p<0.001). Conclusions Resident cost awareness and ability to accurately estimate laboratory order costs improved significantly after implementation of a comprehensive EHR cost display for all laboratory orders. The improvement in cost estimation accuracy for imaging orders, which did not have costs displayed, suggested a possible spillover effect generated by providing a cost context for residents.

Return to Play After Hand and Wrist Fractures

Wrist and hand injuries are common among athletes, and can lead to considerable disability. Dislocations and soft tissue injuries are common and require prompt recognition and treatment. Accurate diagnosis and early immobilization are often key to getting players back to their sport early. Some injuries require surgery; operative intervention allows the player to return to their sport more quickly or with less long-term disability. This article discusses the spectrum of injury from distal radius fractures to mallet fingers, and offers some general guidelines for the surgeon in how to counsel and treat athletes with these problems.

Effects of Fatigue on Driving Safety: A Comparison of Brake Reaction Times in Night Float and Postcall Physicians in Training

BACKGROUND Concerns about duty hour and resident safety have fostered discussion about postshift fatigue and driving impairment. OBJECTIVE We assessed how converting to a night float schedule for overnight coverage affected driving safety for trainees. METHODS Brake reaction times were measured for internal medicine and orthopaedic surgery resident volunteers after a traditional 28-hour call shift and after a night float shift. We conducted matched paired t tests of preshift and postshift reaction time means. Participants also completed the Epworth Sleepiness Scale pre- and postshift. RESULTS From June to July 2013, we enrolled 58 interns and residents (28 orthopaedic surgery, 30 internal medicine). We included 24 (41%) trainees on night float rotations and 34 (59%) trainees on traditional 28-hour call shifts. For all residents on night float rotations, there was no significant difference pre- and postshift. An increase in reaction times was noted among trainees on 28-hour call rotations. This included no effect on reaction times for internal medicine trainees pre- and postshift, and an increase in reaction times for orthopaedic trainees. For both night float and traditional call groups, there were significant increases in the Epworth Sleepiness Scale. CONCLUSIONS Trainees on traditional 28-hour call rotations had significantly worse postshift brake reaction times, whereas trainees on night float rotations had no difference. Orthopaedic trainees had significant differences in brake reaction times after a traditional call shift.

Preventative Care in Orthopedics: Treating Injuries Before They Happen

By 2025, it is estimated that the annual cost of treating osteoporosis-related fractures in the United States will be 25 billion dollars, which is 10 billion dollars more than was spent in 2010. As healthcare costs in the United States continue to skyrocket, it is imperative that orthopedic surgeons take an active role in avoiding preventable injury and disease. For orthopedic surgeons, preventative medicine will include promoting bone health and educating patients on injury prevention. By incorporating these principles into residency and fellowship education, and by leveraging the electronic medical record to support preventive care through systematic reminders, orthopedic surgeons have a critical opportunity to take a leading role in promoting prevention to our patients.

Cost-Effective Management of Stenosing Tenosynovitis

PURPOSE Stenosing tenosynovitis (STS) is a common condition treated by hand surgeons. Limited evidence exists to support the nonsurgical management of STS. The purpose of this study was to prospectively evaluate a cohort of patients with STS, and to determine the strategy for treating patients with this condition that is most cost effective in terms of dollars reimbursed by payers. METHODS Prospective data were collected on patients diagnosed with STS between March 2014 and September 2014. All patients were initially treated with a corticosteroid injection. Patients with persistent symptoms were given the option of injection or surgery. A maximum of 3 injections were offered. All patients were evaluated every 6 months through office appointments or phone calls. A cost analysis was performed in our cohort using actual reimbursement rates for injections, initial and established patient visits, and facility and physician fees for surgery, using the reimbursement rates from the 6 payers covering this patient cohort. Cost savings were calculated based on offering 1, 2, and 3 injections. RESULTS Eighty-eight digits in 82 patients were followed for an average of 21.9 months (range, 18.7-22.7 mo) after an initial corticosteroid injection. Thirty-five digits went on to surgical release, whereas 53 digits were treated nonsurgically. Had all patients initially undergone surgery, the cost would have totaled
