Distal radius fractures are the most common upper extremity fracture, representing one-sixth of all fractures treated in emergency departments nationwide. Beyond the initial reduction and immobilization of these fractures, providing proper followup to ensure maintenance of the reduction and identify complications is necessary for optimal recovery of forearm and wrist functions. We sought to identify the clinical and demographic factors that characterize patients with distal radius fractures who do not return for followup and to assess the underlying causes for their poor followup rates. Compared with patients who were compliant with followup, those lost to followup had lower Physical and Mental Health scores on the SF-36 forms, more often were treated nonoperatively, and more likely had not surpassed secondary education. However, we found no difference between these two groups based on age, gender, mechanism of injury, marital status, or hand dominance. Early identification of patients who potentially are noncompliant can result in additional measures being taken to ensure the patient's return to the treating hospital and physicians. This in turn will prevent complications attributable to lack of followup and allow more accurate assessment of results, thereby improving patient outcomes

BACKGROUND: To our knowledge, no study to date has compared the use of spinal and general anesthesia in patients undergoing operative fixation of an unstable ankle fracture. The purpose of this study was to assess the effects of anesthesia type on postoperative pain and function in a large cohort of patients. METHODS: Between October 2000 and November 2006, 501 patients who underwent surgical fixation of an unstable ankle fracture were followed prospectively. Patients receiving spinal anesthesia were compared with a cohort who received general anesthesia. All patients were evaluated at three, six, and twelve months postoperatively with use of standardized, validated general and limb-specific outcome instruments. Standard and multivariable analyses comparing outcomes at these intervals were performed. RESULTS: Four hundred and sixty-six patients (93%) who had been followed for a minimum of one year met the inclusion criteria. Compared with the general anesthesia group, the spinal anesthesia group had a greater mean age (p = 0.005), higher classification on the American Society of Anesthesiologists system (p = 0.03), and a greater number of patients with diabetes (p = 0.02). There was no difference in sex distribution between the groups. At three months, patients who received spinal anesthesia had significantly better pain scores (p = 0.03) and total scores on the American Orthopaedic Foot and Ankle Society outcome instrument (p = 0.02). At six months, patients in the spinal anesthesia group continued to have better pain scores (p = 0.04), but there was no longer a difference in total scores (p = 0.06). At twelve months, no difference was detected between the groups in terms of functional or pain scores. There was no difference in complication rates between the groups. CONCLUSIONS: Patients who undergo fixation of an ankle fracture under spinal anesthesia seem to experience less pain and have better function in the early postoperative period. We recommend that, unless there is a specific contraindication, patients should be offered spinal anesthesia when undergoing operative fixation of an ankle fracture.

Hip dislocations are uncommon injuries that result from high-energy mechanisms. These patients require careful trauma evaluation to rule out concomitant injuries. Early closed or open reduction that is performed within 6 hours and close radiological follow-up is recommended to obtain the best possible results. It is also essential to educate the patient regarding the potential sequelae and follow them for evidence of osteonecrosis and posttraumatic arthritis

BACKGROUND:: The purpose of this article was to compare clinical and functional outcomes of surgically treated trimalleolar fractures with bimalleolar and unimalleolar ankle fractures. METHODS:: A prospective database was established to enroll all unstable ankle fractures treated operatively at our institution from October 2000 to July 2005. Demographic data on 456 patients, who sustained an unstable fracture of the ankle and were treated surgically, were entered into a database, and the patients were prospectively followed up. Of these 309 patients who had at least 1-year follow-up, 54 patients sustained an ankle fracture with involvement of the posterior malleolus. Two hundred fifty-five patients had an ankle fracture without involvement of the posterior malleolus. Of the 54 posterior malleolus fracture, 20 underwent fixation of the posterior malleolus. All patients were followed up at 3 months, 6 months, and 12 months after surgery and assessed functionally with Short Musculoskeletal Function Assessment and American Orthopaedic Foot and Ankle Society Scores. RESULTS:: There was no difference in age, sex distribution, or American society of anesthesiologists classification or incidence of diabetes between the two groups. At 1-year follow-up, all patients improved their function and pain status. Using the American Orthopaedic Foot and Ankle Society, patients with posterior malleolus fracture were significantly worse both for total score (p = 0.004) and pain function (p = 0.002). At 2-year follow-up, there was no significant difference in a smaller group of patients (41 patients). Using the Short Form-36, there was a significant difference seen with vitality and social function subgroups at 1 year. Using the Short Musculoskeletal Function Assessment, there was a significant difference at 1 year for dysfunction index (p = 0.04) for the trimalleolar group. CONCLUSION:: Most patients after unstable ankle fractures treated surgically do well; however, some patients continue to have some pain and dysfunction at 1 year. There was a significant difference in outcomes comparing patients with unstable ankle fractures associated with and without posterior malleolus fractures. The presence of a posterior malleolus fracture may indicate higher energy of injury, and it does seem to result in worse outcomes at 1 year, but this seems to even out over time as was seen at 2-year follow-up in a smaller group of patients

Fractures of the distal humerus can be difficult to treat due to the periarticular nature of these injuries and the complexity of the elbow joint. Although anatomic and timely repair of the distal humerus with meticulous handling of soft tissues and appropriate postoperative therapy all help to optimize results, an open fracture presents other challenges that may limit successful outcomes in spite of these measures. Open fractures have been found to affect younger males involved in high-energy injuries, as well as older, osteoporotic females involved in lower energy situations. Successful management of these injuries requires urgent and aggressive soft tissue management, skeletal stabilization, and treatment of neurovascular insult (if applicable). This article presents a review of the current literature available concerning the epidemiology, assessment and examination, treatment options, complications, and outcomes of patients with open distal humerus fractures

The diagnostic and therapeutic modalities utilized in the management of pelvic ring fractures depend on patient characteristics, mechanism of injury, and hemodynamic status at the time of presentation. Knowledge of the complex anatomy and biomechanics of pelvic stability may guide appropriate initial management strategies. Even with the development of specific treatment algorithms and advances in both diagnostic and operative techniques, fractures of the pelvis continue to cause significant morbidity and mortality. The current paper reviews the diagnosis and management of pelvic ring fractures, focusing on current concepts with respect to initial assessment and treatment protocols, including the identification of associated injuries and emergency methods of provisional pelvic stabilization

Various treatment options exist for distal radius fractures, and the complications associated with operative and nonoperative management are well documented in the literature. While surgical management with the use of various buttress and locked plating constructs has gained popularity, the long-term outcomes of these plating techniques have not yet significantly demonstrated improved outcomes, as compared to adequately reduced nonoperative measures. Furthermore, this operative technique can be associated with failures and complications. We present a case report of one volar-plate construct requiring revision, secondary to loss of fracture reduction, with no evidence of implant loosening or failure. A literature review on the complications associated with these plate constructs is also presented

The goals of this study were to find associations between anterior and posterior ring injuries, provide a descriptive comparison of pelvic ring disruptions as assessed by plain radiography, and compare the value of computed tomography (CT) over plain radiography in evaluating anterior and posterior structures. A retrospective review of radiographic reports and records identified 142 patients with pubic ramus fractures as observed by plain radiography. A statistical analysis was performed to test the associations between anterior ring injury as assessed by plain radiography and posterior ring injury as assessed by CT. Forty-five point five percent of patients with bilateral ramus fractures and 42.0% of patients with dual-ramus fractures had concomitant sacral fractures not observed on plain radiographs. These occult sacral fractures were found in only 11.1% of patients with inferior ramus fractures. The type of pubic injury on plain radiographs may be predictive of posterior ring injury, and therefore may help determine injury energy and severity, determine the need for further imaging studies, and help guide clinical management. Although CT is highly sensitive in identifying both anterior and posterior pubic ring injuries, elderly patients with simple fractures of a single pubic ramus are less likely to suffer from pelvic instability and thus may not benefit from CT

INTRODUCTION: Wrong-site surgery is defined as an operation conducted at the wrong site, on the wrong person, or resulting in the wrong procedure. Since 1993, more than 2200 wrong-site surgeries have been reported by the National Practitioner Data Base. A 2005 survey reported, 5.6% of replying academy fellows encountered a wrong-site surgery incident. Multiple interventions have been since suggested for prevention of these occurrences by the American Academy of Orthopaedic Surgeons and Joint Commission on Accreditation of Healthcare Organizations. MATERIALS AND METHODS: This institutional review board-approved study was conducted to investigate patient compliance and reliability in marking the surgical site. Two hundred patients undergoing orthopedic surgery who agreed to participate were enrolled at the time of preoperative testing and clearance for surgery. The patients received instructions to mark the surgical site with a 'YES.' Patient data collected included age, sex, procedure type and location, history of previous orthopedic surgeries, workmen's compensation status or motor vehicle collision involvement, employment status, primary language, level of education, presence of depression or toxic habits, and the time between enrollment and day of surgery. RESULTS: We achieved an overall compliance rate of 68.2%. There was no difference with respect to sex, tobacco use or history of depression, level of education or occupation, workmen's compensation, or government insurance status. The mean age of compliant patients was 48.6 years versus 53.3 years for those who did not comply (P = 0.05). About 72% of those who spoke English as a primary language complied, as opposed to 49% in others (P = 0.009). The time between enrollment and surgery was 10.4 days in compliant patients versus 23.1 days in noncompliant patients (P = 0.05). No statistically significant difference was noted with all other variables recorded. In no instance did patients mark the wrong side or make any marks likely to contribute to the wrong operation. CONCLUSIONS: Patient's ability to be involved in this preventative measure is independent of most demographic variables previously thought to be significant. However, in view of the 68.2% compliance, patient involvement in surgical site marking is unreliable and may not help in decreasing the chances of wrong-site surgery

Stress radiographs are useful in determining the amount of ligamentous laxity present following trauma. The results may be helpful in determining diagnosis, surgical indications, and the type and timing of rehabilitation. Some techniques for obtaining stress radiographs involve specific patient positioning or manually applied force; others require use of a particular testing device. Stress radiographs may be obtained for a variety of anatomic areas and joints. The parameters that define abnormality on stress radiographs should be compared with those of clinical findings. The use of common and novel methods to obtain stress radiographs has led to improved identification and diagnosis of many orthopaedic pathologies. Some of these techniques have been developed with the aim of reducing patient discomfort or minimizing the clinician's exposure to radiation.
