BACKGROUND: The goal of this review was to compare the functional outcomes of patients less than 60 and greater than or equal to 60 years old following operative stabilization of unstable ankle fractures. The review was conducted as a retrospective analysis of prospectively collected data at two level one trauma centers and a tertiary referral academic center. MATERIALS AND METHODS: All patients operatively treated for an unstable ankle fracture were entered into a database and prospectively followed. The postoperative protocol was standardized for all patients. Baseline characteristics, complications, additional surgery, functional status and the American Orthopaedic Foot and Ankle Society score (AOFAS) were assessed. The intervention chosen was open reduction and internal fixation of unstable ankle fractures. AOFAS hindfoot score and Short Musculoskeletal Functional Assessment (SMFA) questionnaire were used as the main outcome measures in the study. A p < 0.05 was considered significant. RESULTS: Three hundred sixty-nine (369) patients were entered into the database, 313 (84.8%) were less than 60 years old. At 3 months, 57% (32/56) of patients greater than or equal to 60 years old reported limitation of activities versus 33% (103/313) of patients less than 60 years old (p = 0.005). At 6 and 12 months, these percentages improved to 41% versus 10% (p = 0.001), and 29% versus 7.4% (p = 0.001) for older and younger individuals respectively. However, when compared to their baseline scores, both groups achieved a return to pre-injury status. Total AOFAS scores were not significantly different at 3, 6, or 12 months (p = 0.431). CONCLUSION: Operative fixation of unstable ankle fractures in patients greater than or equal to 60 years old can provide a reasonable functional result at the 1-year followup with a return to preoperative baseline even though they report more limitation of activities than younger patients

There has been increased emphasis on validated, patient-reported functional outcomes after orthopaedic interventions for various conditions. The few reports on these types of outcomes after treatment of fracture nonunions are limited to specific anatomic sites, limited by small numbers, and retrospective. To determine whether successful healing of established long-bone nonunions resulted in improved functional outcomes and reduction in patient-reported pain scores, we prospectively followed 80 patients. These patients had a mean of 1.4 surgical procedures before enrollment and a mean of 18 months had elapsed from previous surgery until enrollment. Baseline data and functional scores were obtained before intervention. Seventeen of the 80 patients (21%) had positive intraoperative cultures. At a mean of 18.7 months (range, 12-36 months), 72 (90%) nonunions had healed. Patients with healed nonunions scored better on the Short Musculoskeletal Functional Assessment. Pain scores among all patients improved compared with baseline, but to a greater degree in patients who achieved healing by final followup. Our data suggest improvement in pain scores is seen in all patients after surgery, whereas successful internal fixation leads to improved function. LEVEL OF EVIDENCE: Level III, therapeutic study.

BACKGROUND: Management of chronic posttraumatic osteomyelitis remains an important challenge in orthopaedics. In this investigation, 43 patients at a large university hospital were retrospectively identified who had been diagnosed with chronic osteomyelitis at 44 sites. METHODS: Diagnosis was based on the patient's history and physical examination, laboratory values, radiological evaluation, and intraoperative specimens. Patients' charts were reviewed and follow-up was obtained on 33 patients in whom Short Musculoskeletal Functional Assessment (SMFA) questionnaires were obtained. RESULTS: The mean follow-up of the cohort was 21.1 months (range, 10 to 54 months). Sites involved included: tibia (55%) and femur (36%), with the remainder involving the pelvis, radius/ulna, and calcaneus. Blood, bone, or wound aspirate cultures were positive in 85%, most commonly for Staphylococcus aureus. 84% of the patients in this investigation were completely cured after a single surgical intervention, removal of hardware and a course of intravenous antibiotics. Three patients required additional surgical intervention and two remained infected. Ultimately, the cohort reached a cure rate of 94%. SMFA data revealed that patients had a dysfunction score of 53.8 and bother index of 51.5, with 50 being the normal for the general population. CONCLUSION: The patients in this cohort functioned at a level less than one standard deviation below the general population. These results suggest that patients with chronic posttraumatic osteomyelitis do not function significantly below that of the normal population following eradication of their infections

Ankle stability in ankle fractures is dependent on multiple factors. The medial malleolus and the associated deltoid ligament provide for ankle stability on the medial side. Over the years, the relative importance of this medial malleolar osteoligamentous complex (MMOLC) has been debated. This review will describe the evolution of ankle fracture surgery from the perspective of the contribution of the MMOLC to re-establishing ankle stability. Also discussed are the surgical and nonsurgical treatment options, various presentations of medial sided injuries in ankle fractures, and, finally, current recommendations for fixation

Prior studies and techniques for harvesting iliac crest bone have shown significant postoperative pain, disability, and poor cosmesis. This retrospective study was conducted to examine bone graft donor-site morbidity by evaluating functional outcomes in patients who have undergone a modified anterior harvesting approach. The medical charts and hospital records of 43 patients were retrospectively reviewed over a 6-year period. Demographic information, operative notes, laboratory results, and the American Society of Anesthesiologists (ASA) classification were recorded. All patients were evaluated retrospectively at a mean 41 months after bone-graft harvesting. Patients available for follow-up were asked to quantify their pain level at the donor-site on a visual analog pain scale (0-10). They also completed SMFA forms, as well as a survey pertaining to sensory deficits, gait disturbances, and cosmetic appearance. Forty-four patients met the inclusion criteria consisting of 25 males and 18 females, mean age 47 years (range, 22 to 80 years). A total of 32 (73%) patients were available for long-term follow-up at a mean of 41.3 months (range, 8 to 83 months). Eight (25%) of these patients reported minimal postoperative pain at time of follow-up. Three of 32 (9%) patients reported minor ambulation difficulty as a result of donor-site pain. Other minor complications included hypertrophic scar formation (7%) and hematoma/seroma (3%). There were no major complications reported, such as deformity at the crest site (0%) or infection (0%). SMFA scores demonstrated a mean dysfunction score of 48.5 (range, 41.8 to 71.1) and a bother index of mean 47.9 (range, 42.6 to 73.9). Utilizing the anterior approach in iliac crest bone harvesting provides an abundant supply of both cortical and cancellous bone, an aesthetically favorable scar, and decreased postoperative donor-site pain. There were very few complications seen in our cohort as compared to previous studies with very good long-term functional outcomes

Two cases are presented in which adult, precontoured, lower-extremity periarticular locking plates were utilized for fixation of subtrochanteric femur fractures in pediatric patients. Recognition of the fact that a distal tibial locking plate in a small child and a proximal tibial locking plate in an adolescent anatomically ft the proximal femur in each case may provide a surgeon treating subtrochanteric hip fractures in this population increased options for operative stabilization

BACKGROUND: This study investigated which variables influence patients' return to sports after operative fixation of an unstable ankle fracture. MATERIALS AND METHODS: Over a 5-year period, 488 patients underwent surgical repair of an unstable ankle fracture. 243 patients preoperatively identified themselves as participating in vigorous activity. Clinical evaluation, functional outcome scores, and radiographic findings were reviewed retrospectively. RESULTS: At 3 months postoperatively, only 3% of all patients had returned to full sports. At 6 months, 14% of patients had returned, while at one year, only 24% of patients had returned. Younger age was predictive of return to sports by 3 months (p = 0.02), 6 months (p = 0.02) and 12 months (p = 0.0001). Males were more likely to return to sports at 6 (p = 0.001) and 12 months (p = 0.040). At 1 year, 88% of recreational athletes had returned to sports, while only 11.6% of competitive athletes had returned to sports (p = 0.043). At 12 months, bimalleolar injuries were more likely to return to sports than unimalleolar ankle fractures (p = 0.042). Furthermore, patients without an associated syndesmotic injury were more likely to return to athletic activities at 12 months (p = 0.011). A patient with an ASA of one or two was ten times more likely to return to sports versus a patient with an ASA of three or four (odds ratio > 10, p = 0.010). CONCLUSION: Predictors of return to sporting activities at one year include younger age, male gender, no or mild systemic disease, and a less severe ankle fracture. Negative predictors include older age, female gender, and the presence of severe medical comorbidities

BACKGROUND: The outcome of operatively treated capitellar fractures has not been reported frequently. The purpose of the present study was to evaluate the clinical, radiographic, and functional outcomes following open reduction and internal fixation of capitellar fractures that were treated with a uniform surgical approach in order to further define the impact on the outcome of fracture type and concomitant lateral column osseous and/or ligamentous injuries. METHODS: A retrospective evaluation of the upper extremity database at our institution identified sixteen skeletally mature patients (mean age, 40 +/- 17 years) with a closed capitellar fracture. In all cases, an extensile lateral exposure and articular fixation with buried cannulated variable-pitch headless compression screws was performed at a mean of ten days after the injury. Clinical, radiographic, and elbow-specific outcomes, including the Mayo Elbow Performance Index, were evaluated at a mean of 27 +/- 19 months postoperatively. RESULTS: Six Type-I, two Type-III, and eight Type-IV fractures were identified with use of the Bryan and Morrey classification system. Four of five ipsilateral radial head fractures occurred in association with a Type-IV fracture. The lateral collateral ligament was intact in fifteen of the sixteen elbows. Metaphyseal comminution was observed in association with five fractures (including four Type-IV fractures and one Type-III fracture). Supplemental mini-fragment screws were used for four of eight Type-IV fractures and one of two Type-III fractures. All fractures healed, and no elbow had instability or weakness. Overall, the mean ulnohumeral motion was 123 degrees (range, 70 degrees to 150 degrees). Fourteen of the sixteen patients achieved a functional arc of elbow motion, and all patients had full forearm rotation. The mean Mayo Elbow Performance Index score was 92 +/- 10 points, with nine excellent results, six good results, and one fair result. Patients with a Type-IV fracture had a greater magnitude of flexion contracture (p = 0.04), reduced terminal flexion (p = 0.02), and a reduced net ulnohumeral arc (p = 0.01). An ipsilateral radial head fracture did not appear to affect ulnohumeral motion or the functional outcome. CONCLUSIONS: Despite the presence of greater flexion contractures at the time of follow-up in elbows with Type-IV fractures or fractures with an ipsilateral radial head fracture, good to excellent outcomes with functional ulnohumeral motion can be achieved following internal fixation of these complex fractures. Type-IV injuries may be more common than previously thought; such fractures often are associated with metaphyseal comminution or a radial head fracture and may require supplemental fixation
