Abstract
The evaluation and treatment of chronic ankle pain presents a challenge to the orthopaedic surgeon. A detailed history helps to determine causative factors resulting from earlier trauma or surgery. A careful physical examination and radiographic studies also are helpful in making an accurate diagnosis, which is the basis for choosing a specific and effective treatment regimen.

Abstract
Plantarflexion of the second metatarsophalangeal (MTP) joint with intra-articular injection has previously been observed and commented upon, and the purpose of this study was to determine motion of the lesser toes with direct fluid infusion into the lesser MTP joints. Fluid distension was found to cause variable postural changes in all lesser toes; the most consistent change was plantarflexion of the second metatarsophalangeal joint. Dorsiflexion of the third, fourth, and fifth MTP joints was observed, but less reliable than plantarflexion of the second MTP joint. The average volume in each of the lesser MTP joints was less than 1 cc. Plantarflexion of the second MTP joint was usually, but not always, indicative of intra-articular distention. Aspiration of these joints (given their small volume capacity) may not be a reliable or therapeutically useful technique.

Abstract
BACKGROUND Dedicated orthopaedic residency training in the musculoskeletal discipline of foot and ankle is an important contribution to the development of a well-rounded orthopaedic surgeon. Current residency training guidelines are vague and do not require specific experience or proficiency in this discipline. METHODS A one-page questionnaire on commitment to foot and ankle education in American Orthopaedic Surgery residency training programs was completed by all 148 program directors. RESULTS Eighty of the programs (54.1%) had a single faculty member dedicated to foot and ankle orthopaedics, while 21 (14.2%) did not have a faculty member with a specific interest or commitment to problems related to the foot and ankle. Fifteen programs (10.1%) did not have a committed faculty member, nor did their residents have a clinical rotation dedicated to foot and ankle. Ninety-six programs (64.9%) had at least one clinical rotation dedicated to foot and ankle. Fifty-two (35.1%) did not. Thirty-three (34.7%) of those programs with a dedicated foot and ankle experience assigned residents during at least two periods of their training. Of those programs with a single foot-specific rotation, the most common year for training was in the PGY3 year (27 of 63, 42.9%). Of the 60 months' duration of most orthopaedic residency programs, 39 of 96 (40.6%) programs with a dedicated clinical foot and ankle rotation allocated an average of 12 weeks to foot and ankle. Twenty-six (27.1%) allocated less than 3 total months, and 31 (32.3%) allocated 16 to 24 weeks of dedicated foot and ankle experience. CONCLUSIONS Current residency training in the United States does not universally require a commitment to foot and ankle education. A large number of residency programs do not have a faculty member committed to foot and ankle education, and almost one-third have no time specifically allocated to foot and ankle education.

Abstract
BACKGROUND We studied foot and ankle (F/A) injuries that occurred in motor vehicle accidents treated in a Level 1 trauma center. METHODS The records of F/A injuries of 2248 consecutive orthopedic patients were reviewed to find foot and ankle injuries. RESULTS Pilon fractures were common. Motor Vehicle Accident (MVA) occupants with F/A injuries had a higher injury Severity Score than those without (17.9 vs. 11.6, p <. 001). MVA F/A injury risk was higher without restraint [relative risk ratio (rrr) 1.68, p <. 0032] than with restraint except for air bagged drivers who were similar to unrestrained drivers (rrr 1.18, p > .05, NS). CONCLUSION Patients with F/A injuries may have serious associated injuries. Air bags may not protect feet.

Abstract
The purpose of this study was to determine the accuracy and the specificity of an optimum technique of posterior talocalcaneal/posterior subtalar (PST) joint arthrography and anesthetic injection in patients with hindfoot pain. Fifty-five PST joints were studied in 55 patients. The posteromedial approach was used in the first 24 patients, followed by an anterolateral approach in 31 patients. The ease of performance, success of confirming PST needle position, and adverse effects were noted. After contrast injection, a combination of 1% lidocaine and 0.5% bupivacaine was injected. Results consisted of 47 arthrographically confirmed PST injections. The posteromedial approach was deemed more difficult; three patients had tendon sheath opacification and four had unwanted anesthesia of the toes. The anterolateral approach was technically easier and no extra-articular structures were visualized or anesthetized. Therefore, PST arthrography with anesthetic injection is optimized with an anterolateral approach.

Abstract
It is widely accepted that operative fixation of unstable ankle fractures yields predictably good outcomes in the general population. The current literature, however reports less acceptable results in the geriatric population age 65 years and older. The current study analyzes the outcome of the surgical treatment of unstable ankle fractures in patients at least 65 years old. Twenty three patient over 65 years old were surgically treated after sustaining 21 (91%) closed and 2 (9%) open grade II unstable ankle fractures. Fractures were classified according to the Danis-Weber and Lauge-Hansen schemes. Fracture type was predominantly Weber B (21/23, 91%), or supination external rotation stage IV (21/23, 91%). Fracture union rate was 100%. There were three significant complications including a lateral wound dehiscence with delayed fibular union in an open fracture dislocation, and two below knee amputations, neither of which was directly related to the fracture treatment. There were three minor complications; one superficial wound infection and two cases of prolonged incision drainage, all of which resolved without further surgical intervention. Complications were associated with open fractures and preexisting systemic disease. These results indicate that open reduction and internal fixation of unstable ankle fractures in geriatric patients is an efficacious treatment regime that with results that are comparable to the general population.

Abstract
Fifteen fresh-frozen cadaveric lower extremities were studied to evaluate the reliability of measuring subtalar motion using a bubble inclinometer. There was high intra-observer reliability for manual inversion and eversion of the subtalar joint with the tibiotalar joint locked and unlocked. Poor correlation of radiographic and clinical measurements questioned the validity of bubble inclinometer measurements. The contribution of the tibiotalar joint to apparent subtalar motion, as measured clinically and radiographically, was found to be one-third of the arc of motion, as compared to motion measured clinically and radiographically with the tibiotalar joint locked.

Abstract
Although the concept of a total ankle arthroplasty has been advanced as a method for treating severe ankle arthritis, the clinical experience with all of the models developed has been discouraging. Both the constrained designs, which maximize joint contact area by restricting the available motion, and the unconstrained designs, which allow more normal motion at the expense of higher contact stresses, uniformly result in implant loosening, pain, and clinical failure in 2 to 7 years. This has led to the recommendation against the use of a total ankle arthroplasty except in very low-demand patients. Failure of ankle implants can be ascribed to either anatomic considerations (e.g.--the talus is too small to accommodate the stress transfers of a prosthesis), or mechanical etiologies. Abnormal 3-dimensional motion of the ankle following arthroplasty would fall into the latter category. This study examined the motion that occurs after implantation of an unconstrained-type total ankle arthroplasty. Using previously validated methodology, axially loaded ankle specimens were cycled through an arc of plantarflex/dorsiflexion while measuring the resulting coupled internal/external and varus/valgus rotations. The average coupled motions in prosthetic ankles were not significantly different than their intact controls. There was, however, a significantly increased amount of hysteresis (defined as the difference between the upper and lower pathways of coupled motion at any given sagittal position) that occurred as the ankle was dorsiflexed and plantar flexed. The increased hysteresis was seen in both the axial and coronal planes. This indicates that there was a greater permitted envelop of motion in the prosthetic ankles compared to normal ankles. It is hypothesized that this subtle change in ankle kinematics caused by the arthroplasty leads to abnormal stress transfer at the prosthesis-bone interface, thereby promoting early implant failure.

Abstract
To evaluate the utility of bone scans in determining the treatment of diabetic patients with foot ulcers, a retrospective study was conducted. Medical records were reviewed for clinical signs of infection, laboratory data, and the radiologists' interpretations of imaging studies. During the study period, 34 bone scans were obtained by the treating physicians to evaluate diabetic foot ulcers. Among these, 22 of 34 bone scans were markedly confirmatory of being "consistent with osteomyelitis," 8 of 34 were moderately confirmatory ("indeterminate with regard to osteomyelitis"), and 4 of 34 were not confirmatory ("not consistent with osteomyelitis"). Of the 22 patients in the markedly confirmatory group, eight patients with clinical findings of uncontrolled infection or gangrene were treated with partial or complete amputation, whereas all others (14 patients) were treated with local wound care+/-intravenous antibiotics. Among the eight bone scans interpreted as indeterminate, three patients required partial or complete amputation, whereas the other five patients were managed with local wound care. Of the four patients with nonconfirmatory bone scans, two patients had evidence of dry gangrene and required amputation, whereas the other two patients did not have clinical evidence of infection or gangrene and were treated with local wound care. There was no significant difference in the amputation rate for patients with confirmatory, indeterminate, or nonconfirmatory bone scans for osteomyelitis (36%, 37%, and 50%, respectively) (P > 0.5). Therefore, the authors concluded that the ultimate treatment should be based on clinical indicators of the presence of uncontrolled infection or gangrene rather than on bone scan findings.

Abstract
Ten patients were identified with traumatic, complete common peroneal nerve palsy, with no previous foot or ankle surgery or trauma distal to the knee, who had undergone anterior transfer of the posterior tibial tendon to the midfoot. Six of these patients had a transfer to the midfoot and four had a Bridle procedure with tenodesis of half of the posterior tibial tendon to the peroneus longus tendon. Average follow-up was 74.9 months (range, 18-351 months). All patients' feet were compared assessing residual muscle strength, the longitudinal arch, and motion at the ankle, subtalar, and Chopart's joint. Weightbearing lateral X-rays and Harris mat studies were done on both feet. In no case was any valgus hindfoot deformity associated with posterior tibial tendon rupture found. It seems that the pathologic condition associated with a posterior tibial tendon deficient foot will not manifest itself if peroneus brevis function is absent.

Abstract
A total of 329 patients with osteoblastoma were retrospectively reviewed from the archives of the Armed Forces Institute of Pathology, of which 41 (12.5%) presented with tumors in the foot and ankle. This was the third most common site of disease after the spine and femur. Overall, the mean age was 22.5 years, which was the same for the foot and ankle subset of patients; however, there was a significant male predominance in foot and ankle patients compared with the whole group. The majority of patients were skeletally mature (85.4%). Clinically, most patients presented with pain (97.2%), although one-third of the total related a history of antecedent trauma. The interval between the onset of symptoms and biopsy was 84 days (range, 0-572 days). Radiographically, the majority of lesions were in the hindfoot (N = 18; 44%) of which 16 of 18 tumors (89%) were in the talus. Of these, one-half were subperiosteal and dorsally based and were associated with osseous tumor matrix and a soft tissue mass. Two osteoblastomas, both in the metatarsals, transitioned into sarcomas; the rest were histologically benign. For diagnostic purposes, it was essential to obtain clinical, radiographic, and histologic correlation.

Abstract
Subcalcaneal pain is a common complaint presented to the orthopaedist. Excessive attention to mechanical or traumatic causes may result in an improper diagnosis if rheumatologic or systemic conditions are not considered in the differential diagnosis. Systemic conditions associated with heel pain are reviewed and a conservative treatment protocol is presented that should help to obtain a correct diagnosis and to lead to effective management of this common condition.

Abstract
Thromboembolic disease presents a potentially fatal complication to patients undergoing orthopaedic surgery. Although the incidence after hip and knee surgery has been studied and documented, its incidence after surgery of the foot and ankle is unknown. For this reason, a prospective multicenter study was undertaken to identify patients with clinically evident thromboembolic disease to evaluate potential risk factors. Two thousand seven hundred thirty-three patients were evaluated for preoperative risk factors and postoperative thromboembolic events. There were six clinically significant thromboembolic events, including four nonfatal pulmonary emboli, after foot and ankle surgery. The incidence of deep vein thrombosis was six of 2733 (0.22%) and that of nonfatal pulmonary emboli was four of 2733 (0.15%). Factors found to correlate with an increased incidence of deep vein thrombosis were nonweightbearing status and immobilization after surgery. On the basis of these results, routine prophylaxis for thromboembolic disease after foot and ankle surgery probably is not warranted.
