Predictors of mortality after hip fracture: a 10-year prospective study

The role of medical, social, and functional covariates on mortality after hip fracture was examined over a 16-year period. A total of 1109 patients with hip fractures were included in a prospective database. The inclusion criteria were patients who were age 65 years or older, ambulatory prior to fracture, cognitively intact, living in their own home at the time of the fracture, and had sustained a nonpathological femoral neck or intertrochanteric chip fracture. Data were analyzed using a Cox proportional hazards model. Mortality was compared with a standardized population, and standardized mortality ratios were calculated for 1, 2, 3, 5, and 10 years,respectively. The 1-, 2-, 5- and 10-year mortality rates were 11.9%, 18.5%, 41.2%, and 75.3%, respectively. The predictors of mortality were advanced age, male gender, high American Society of Anesthesiologists (ASA)classification, the presence of a major postoperative complication, a history of cancer, chronic obstructive pulmonary disorder, a history of congestive heart failure,ambulating with an assistive device, or being a household ambulator prior to hip fracture. The increased mortality risk was highest during the first year after hip fracture and returned to the risk of the standard population 3 years postoperatively. Males who are 65 to 84 years had the highest mortality risk.     

Functional outcome following one-part proximal humeral fractures: a prospective study

A prospective study was undertaken to determine if patients recover pre-injury level of shoulder function 1 year after 1 part proximal humeral fractures. Of the 67 patients enrolled, 43 were female and 24 male with an average age of 64.8 years (range, 25-90 years). All patients underwent a similar treatment protocol consisting of early therapy for range of shoulder motion and strengthening. Baseline demographics and functional assessment, including the American Shoulder and Elbow Surgeons (ASES) evaluation form and the SF-36, were obtained at the time of injury. Functional and demographic data were evaluated with a Student's t test. Fifty-four patients (80%) completed a 1-year follow-up. By 3 months, all patients attained radiographic and clinical evidence of union and no loss of reduction. At 1 year, the ASES score was similar to pre-injury status (93.7 vs 99.1; P = .12). The range of shoulder motion of the affected side was diminished compared to the unaffected extremity in internal rotation (P < .001) and external rotation (P < .001) but not forward flexion. Patients, who sustain minimally displaced proximal humeral fractures treated nonoperatively, largely returned to preoperative functional status at 1-year follow-up. Patients should be counseled and made aware of the decreased range of shoulder motion following this fracture.     

Surgical management of hip fractures: an evidence-based review of the literature. I: femoral neck fractures

During the past 10 years, there has been a worldwide effort in all medical fields to base clinical health care decisions on available evidence as described by thorough reviews of the literature. Hip fractures pose a significant health care problem worldwide, with an annual incidence of approximately 1.7 million. Globally, the mean age of the population is increasing, and the number of hip fractures is expected to triple in the next 50 years. One-year mortality rates currently range from 14% to 36%, and care for these patients represents a major global economic burden. Surgical options for the management of femoral neck fractures are closely linked to individual patient factors and to the location and degree of fracture displacement. Nonsurgical management of intracapsular hip fractures is limited. Based on a critical, evidence-based review of the current literature, we have found minimal differences between implants used for internal fixation of displaced fractures. Cemented, unipolar hemiarthroplasty remains a good option with reasonable results. In the appropriate patient population, outcomes following total hip arthroplasty are favorable and appear to be superior to those of internal fixation.     

Bridging external fixation and supplementary Kirschner-wire fixation versus volar locked plating for unstable fractures of the distal radius: a randomised, prospective trial

We performed a prospective, randomised trial to evaluate the outcome after surgery of displaced, unstable fractures of the distal radius. A total of 280 consecutive patients were enrolled in a prospective database and 88 identified who met the inclusion criteria for surgery. They were randomised to receive either bridging external fixation with supplementary Kirschner-wire fixation or volar-locked plating with screws. Both groups were similar in terms of age, gender, hand dominance, fracture pattern, socio-economic status and medical co-morbidities. Although the patients treated by volar plating had a statistically significant early improvement in the range of movement of the wrist, this advantage diminished with time and in absolute terms the difference in range of movement was clinically unimportant. Radiologically, there were no clinically significant differences in the reductions, although more patients with AO/OTA (Orthopaedic Trauma Association) type C fractures were allocated to the external fixation group. The function at one year was similar in the two groups. No clear advantage could be demonstrated with either treatment but fewer re-operations were required in the external fixation group.     

The current status of locked plating: the good, the bad, and the ugly

Locked plate technology has evolved in an effort to overcome the limitations associated with conventional plating methods, primarily for improving fixation in osteopenic bone. The development of screw torque and plate-bone interface friction is unnecessary with locked plate designs, significantly decreasing the amount of soft tissue dissection required for implantation, preserving the periosteal blood supply, and facilitating the use of minimally invasive percutaneous bridging fixation techniques. The locked plate is a fixed-angle device because angular motion does not occur at the plate screw interface. The use of locked plate technology allows the orthopaedic surgeon to manage fractures with indirect reduction techniques while providing stable fracture fixation. The secure 'feel' of locked plates, ease of application, and the low incidence of complications noted in early clinical reports have contributed to the proliferation of this technology. Along with reports of clinical successes, as the use of fixed angle/locked plates has increased, clinical failures are being noticed. This review will focus on the biomechanics of locked plate technology, appropriate indications for its use, laboratory and clinical comparisons to conventional plating techniques, and potential mechanisms of locked plate failure that have been observed.     

Fracture-dislocation of the elbow functional outcome following treatment with a standardized protocol

Fracture-dislocation of the elbow is a signiicant injury with mixed outcomes. The purpose of the study was to evaluate patient perceived outcome following surgical stabilization of these complex injuries. Twenty-nine available patients (76%) from 37 identiied with "terrible triad" injury patterns, in- cluding ulnohumeral dislocation, radial head fracture, and coronoid fracture, were available for a minimum 1-year follow-up (mean, 27 months). All patients were evaluated by their treating physician. Radiographic outcome was evaluated at latest follow-up. Functional outcome was based upon DASH, Mayo elbow performance, and Broberg-Mor- rey scores. Complications were recorded. Results included that the average lexion-extension arc of elbow motion was 109 degrees +/- 27 degrees , and the average pronation-supination arc was 128 degrees +/- 44 degrees . Grip strength averaged 72% of the contralateral extremity. The Mayo score was a mean of 81 (range, 45 to 100), the Broberg-Morrey mean was 77 (range, 33 to 100) The mean DASH was 28 (range, 0 to 72). When compared to the age-based normal values, the mean patient's DASH score was 1.4 SD worse than an average person of the same age None of the injury characteristics, patient demographics or treatment modalities was signiicantly associated with a poor outcome at the 95% conidence interval. Conclusions are that the results with terrible triad injuries are often unsatisfactory, but surgical management with the use of a systematic approach may be beneicial. Our approach led to the restoration of elbow joint stability in all patients.     

Comparison of functional outcomes of total elbow arthroplasty vs plate fixation for distal humerus fractures in osteoporotic elbows

Treating intra-articular fractures about the osteoporotic distal humerus poses a significant challenge. The purpose of this retrospective study was to evaluate functional outcomes for distal humeral fractures treated with total elbow arthroplasty (TEA) or open reduction and internal fixation (ORIF) in a nonarthritic elderly population with osteoporosis. We reviewed the records of all women older than age 60 who had undergone surgical treatment for intraarticular distal humerus fractures (Orthopaedic Trauma Association types 13B and 13C) by 1 of 2 surgeons. Demographic and operative data were obtained, charts were reviewed, and patients were asked to have their outcomes evaluated with the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire and the Mayo Elbow Performance Index (MEPI). Twenty-two patients (23 elbows) were identified, and 2 of these (3 elbows) were excluded. Of the remaining 20 patients, 9 had undergone cemented, semiconstrained TEA as initial treatment, and 11 had undergone ORIF. These 2 groups were compared. Mean follow-up was 14.8 months (range, 6-38 months). There were no significant differences between the TEA and ORIF groups with respect to demographic factors. Final elbow range of motion was 92° flexion-extension arc (arthroplasty group) and 98° (fixation group). Two patients in the arthroplasty group and 2 in the fixation group died. For the remaining patients, mean DASH scores were 30.2 (arthroplasty) and 32.1 (fixation), and mean MEPI scores were 79 (arthroplasty) and 85 (fixation). These differences were not statistically significant. Four TEAs developed radiographic loosening by a mean of 15 months, and 1 of these underwent revision with good outcome. Ten of the 11 fractures in the fixation group healed radiographically; the 1 nonunion with collapse continued to be asymptomatic. Two patients in the fixation group underwent contracture release after union for limited elbow range of motion. Many factors come into play in the treatment of intra-articular distal humerus fractures in patients with osteoporosis. Implant selection must be based on bone quality, expected outcome, and surgeon experience. For these injuries, good outcomes may be obtained with either TEA or ORIF.
