ABSTRACT
PURPOSE: A series of studies have reported a change in the length or thickness of the anterior talofibular (ATFL) and calcaneofibular (CFL) ligaments in patients with chronic ankle instability. However, no study has examined the changes in the angle between the ATFL and CFL in patients diagnosed with chronic ankle instability. Therefore, this study analyzed the change in the angle between the ATFL and CFL in patients diagnosed with chronic ankle instability to confirm its relevance. METHODS: This retrospective study included 60 patients who had undergone surgery for chronic ankle instability. Stress radiographs comprising the anterior drawer test, varus stress test, Broden's view stress test, and magnetic resonance imaging (MRI) were performed in all patients. The angle between the ATFL and CFL was measured by indicating the vector at the attachment site, as seen on the sagittal plane. Three groups were classified according to the angle between the two ligaments measured by MRI: group I when the angle was > 90°, Group II when the angle was 71-90°, and Group III when the angle was ≤ 70°. The accompanying injuries to the subtalar joint ligament were analyzed via MRI. RESULTS: A comparison of the angles between the ATFL and CFL measured on MRI in Group I, Group II, and Group III with the angles measured in the operating room revealed a significant correlation. Broden's view stress test revealed a statistically significant difference among the three groups (p < 0.05). The accompanying subtalar joint ligament injuries differed significantly among the three groups (p < 0.05). CONCLUSION: The ATFL-CFL angle in patients with ankle instability is smaller than the average angle in ordinary people. Therefore, the ATFL-CFL angle might be a reliable and representative measurement tool to assess chronic ankle instability, and subtalar joint instability should be considered if the ATFL-CFL angle is 70° or less. LEVEL OF EVIDENCE: Level III.

BACKGROUND: With the advent of percutaneous plating techniques and anatomical locking plates, open plating combined with percutaneous plating may be a feasible option to reduce pilon fracture soft-tissue complications. The purpose of this study was to evaluate the outcomes of a combined open and percutaneous plating approach for the treatment of pilon fracture. METHODS: Forty-two consecutive patients treated with a combined open and percutaneous plating approach between March of 2010 and February of 2020 for pilon fracture were reviewed retrospectively. The study population consisted of four female patients and 38 male patients with an average age of 47.5 years (range, 15-71 years). The mean follow-up duration was 25.7 months (range, 12-48 months). The combination of a small anterolateral approach and a small anteromedial approach (or a small direct medial approach) was used in all cases. A small posterolateral approach or a small posteromedial approach was added as necessary. RESULTS: The average ranges of ankle sagittal motion and hindfoot coronal motion at 1 year postoperatively were 43.3° (range, 30°-60°) and 47.7° (range, 40°-55°), respectively. The mean 1-year postoperative visual analogue scale score and American Orthopaedic Foot and Ankle Society score were 0.90 (range, 0-4.0) and 94.5 (range, 78-100), respectively. All patients except one achieved bony union. The mean time to union (except in the one case of nonunion) was 4.5 months (range, 3-8 months). Minor wound breakdown occurred in five cases using combined approaches, but these eventually healed with local wound care. There were no major soft-tissue complications and no instances of deep infection. CONCLUSIONS: A combined open and percutaneous plating approach is a feasible option for the treatment of pilon fracture. This combined plating technique involving a combination of a small anterolateral approach and a small anteromedial approach (or a small direct medial approach) yielded satisfactory outcomes without major soft-tissue complications.

OBJECTIVE: Recently, new patient-reported outcome measures (PROMs) of the spine were designed to overcome the limitations of previous spinal PROMs and to consider the whole spine as a single kinetic functional unit. Owing to the significance of spine-hip-knee and global body balance, the spine and lower extremities cannot be considered separately. However, no reports have evaluated lower-extremity functional outcome using PROMs after lumbar spine surgery. The authors aimed to elucidate changes in hip and knee PROMs after lumbar interbody fusion and to evaluate the sagittal spinopelvic radiographic parameters that were most strongly correlated with lower-extremity PROMs. METHODS: In 2018, the authors consecutively evaluated patients who underwent lumbar interbody fusion surgery with at most three levels. Preoperative and 1-year postoperative clinical and radiographic data were assessed. Spinal functional outcomes were measured with the Oswestry Disability Index (ODI), visual analog scale (VAS) for pain, and Scoliosis Research Society-22r (SRS-22r) questionnaire. Lower-extremity functional outcomes were evaluated with the Harris Hip Score (HHS) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Linear regression was used to evaluate the relationship between spinal and lower-extremity PROMs and spinopelvic radiographic parameters. RESULTS: The authors enrolled 67 patients, with a mean age of 66.4 years. The average number of surgical levels was 1.7. All assessed PROMs improved significantly after surgery (p < 0.001 for ODI, p < 0.001 for VAS, p = 0.017 for SRS-22r, p = 0.042 for HHS, and p = 0.033 for WOMAC). Spinopelvic parameters, including lumbar lordosis (LL), pelvic tilt (PT), C7 sagittal vertical axis, and sagittal radiographic parameters of hip and knee, significantly improved after surgery. On linear regression analysis, HHS and WOMAC correlated with LL and PT, respectively (ß = 0.554 and p = 0.043 for correlation of HHS with LL; ß = 1.573 and p = 0.021 for correlation of WOMAC with PT). CONCLUSIONS: The current study demonstrated that lumbar fusion surgery may induce postoperative improvements in lower-extremity functional and radiological outcomes. However, among radiographic parameters, changes in LL and PT were the most strongly associated with lower-extremity PROMs.

Unstable fracture-dislocation of the ankle is a common lower-extremity injury. Treatment is challenging when the fracture-dislocation is open and cannot be treated with conventional open reduction and internal fixation (ORIF). Immediate ORIF may not be possible for severe, unstable ankle injuries, such as those with ischemic foot because of a poor blood supply caused by soft-tissue injury, or open fracture-dislocation of the ankle with a deltoid ligament rupture. We describe a staged treatment for unstable open fracture-dislocation of the ankle with a deltoid ligament rupture. The first stage involves temporary vertical transarticular pinning combined with external fixation. The second stage involves delayed definitive plating with autogenous bone graft for the bone defect of the distal fibula. This staged management is useful in select emergency cases of unstable open fracture-dislocations of the ankle combined with deltoid ligament rupture for which conventional ORIF cannot be performed.

PURPOSE: Previous studies have shown conflicting results regarding the factors affecting the clinical outcome after fusion for degenerative spondylolisthesis. However, no study has compared the best and worst clinical outcome groups using patient-reported outcome measures. We aimed to compare the characteristics of patients with best and worst outcomes following single-level lumbar fusion for degenerative spondylolisthesis. METHODS: 200 patients underwent single-level interbody fusion with a minimum 2-years follow-up were included. We excluded patients with surgical complications already-known to be associated with poor postoperative outcomes, including pseudoarthrosis and postoperative infection. According to 2-year postoperative Oswestry disability index scores, patients were divided into two groups; Best and Worst. Demographic, clinical and radiographic variables were compared between the two groups. RESULTS: Compared with patients in the Best group, those in the Worst group were older (59.5 and 67.0 years, respectively; p = 0.012; odds ratio [OR], 1.143; 95% confidence interval [CI], 1.030-1.269) and had a longer duration of pain from onset (2.6 and 7.2 years, respectively; p = 0.041; OR, 1.021; 95% CI, 1.001-1.041). The cutoff value of pain duration from onset was measured as ≥3.5 years on Receiver operating characteristic analysis. Patients in the Worst group had a lower preoperative angular motion compared to those in the Best group (12.7° and 8.3°, respectively; p = 0.016; OR, 0.816; 95% CI, 0.691-0.963). CONCLUSIONS: Degenerative spondylolisthesis patients of good clinical outcome after single-level lumbar interbody fusion were relatively young, had a short symptom duration before surgery, and a high preoperative instability compared with the patient having poor postoperative clinical outcome. Therefore, these findings should be considered preoperatively when deciding the appropriate individual treatment plan.

Talar injuries that are associated with pilon fractures include talar body fractures, osteochondral defects, and posterior process talar fractures. Pilon fractures, in combination with talar dome fractures, have not yet been reported in the scientific literature. We report the case of a 15-year-old boy who sustained a pilon fracture with a lateral talar dome fracture. The pilon fracture was initially fixed using a temporary external fixator for soft-tissue care. After the swelling subsided, definitive internal fixation was performed. First, the lateral talar dome fracture was directly reduced and fixed using a small anterolateral approach of the ankle. Then, the intra-articular portion of the pilon fracture was directly reduced using the same anterolateral approach and an additional small anteromedial approach, and the extra-articular metaphyseal portion of the pilon fracture was indirectly reduced. The pilon fracture was finally fixed with an anterolateral distal tibia plate, using a submuscular plating technique through the anterolateral approach and a separate proximal skin incision. A medial distal tibia plate was later added using a subcutaneous plating technique through the anteromedial approach and another proximal skin incision. Both the pilon fracture and the lateral talar dome fracture were addressed simultaneously through a combination of the small anterolateral and anteromedial approaches.

BACKGROUND: This study aimed to compare the clinical results between osteochondral autologous transplantation (OAT) and dorsiflexion closing wedge metatarsal osteotomy (DCWMO) in symptomatic adult patients with late-stage Freiberg disease. METHODS: Between 2012 and 2017, patients with late-stage Freiberg disease surgically treated with OAT (12 patients) or DCWMO (15 patients) were retrospectively identified. The American Orthopaedic Foot & Ankle Society-lesser metatarsophalangeal-interphalangeal (AOFAS-LMI) score, visual analog scale score for subjective pain, and range of motion (ROM) were determined preoperatively and at final follow-up. Postoperative complications were also recorded. RESULTS: The AOFAS-LMI score at final follow-up was significantly greater in the OAT group than in the DCWMO group (95.7 vs 87.9, P < .001), whereas plantarflexion at final follow-up was significantly lower in the DCWMO group than in the OAT group (30.0 vs 24.0 degrees, P = .037). The DCWMO group reported more postoperative complications including postoperative joint stiffness, deformity, and pain recurrence. In the OAT group, one patient complained of mild knee pain. CONCLUSION: OAT seemed a better procedure for late-stage Freiberg disease compared with DCWMO in adult patients in terms of postoperative functional score and ROM, with lower complication rates. LEVEL OF EVIDENCE: Level III, retrospective comparative study.

OBJECTIVE: The goal of this study was to evaluate the radiographic and clinical results of instrumentation surgery without fusion for metastases to the spine. METHODS: Between 2010 and 2017, patients with spinal tumors who underwent instrumentation without fusion surgery were consecutively evaluated. Preoperative and postoperative clinical data were evaluated. Data were inclusive for last follow-up and just prior to death if the patient died. Instrumentation-related complications included screw migration, screw or rod breakage, cage migration, and screw loosening. RESULTS: Excluding patients who died within 6 months, a total of 136 patients (140 operations) were recruited. The average follow-up duration was 16.5 months (median 12.4 months). The pain visual analog scale score decreased from 6.4 to 2.5 (p < 0.001) and the Eastern Cooperative Oncology Group scale score improved (p < 0.001). There were only 3 cases (2.1%) of symptomatic instrumentation-related complications that resulted in revisions. There were 6 cases of nonsymptomatic complications. The most common complication was screw migration or pull-out (5 cases). There were 3 cases of screw or rod breakage and 1 case of cage migration. Two-thirds of the cases of instrumentation-related complications occurred after 6 months, with a mean postoperative period of 1 year. CONCLUSIONS: The current study reported successful outcomes with very low complication rates after nonfusion surgery for patients with spinal metastases, even among those who survived for more than 6 months. More than half of the instrumentation-related complications were asymptomatic and did not require revision. The results suggest that nonfusion surgery might be sufficient for a majority of patients with spinal metastases.
ABSTRACT
PURPOSE: The purpose of this study is to compare the acetabular teardrop (the structure located inferomedially in the acetabulum, just superior to the obturator foramen. The medial lip is the interior, and the lateral lip is the exterior of the acetabular wall) with the inferior acetabular rim as anatomical landmarks to measure the acetabular abduction angle (AAD) using coronal CT images from different levels. METHODS: Our retrospective study included 120 pelvic CT scans from patients with non-orthopedic pathologies or stress fractures of the proximal femur. The patients included 60 females with a mean age of 48 years (range 40-66) and 60 males with a mean age of 46 years (range 38-65). Each AAD was measured using coronal plane CT slices from five levels: AAD (+ 10) (10 mm anterior to the femoral head center), AAD (+ 5) (5 mm anterior to the femoral head center), AAD (0) (through the femoral head center), AAD (- 5) (5 mm posterior to the femoral head center), and AAD (- 10) (10 mm posterior to the femoral head center). The measurements were then divided into two groups: teardrop-based AADs [AAD (+ 10), AAD (+ 5), and AAD (0)] and rim-based AADs [AAD (- 5) and AAD (- 10)]. RESULTS: There were no mean significant differences in AAD within the groups, whereas the difference between the groups was significant. The mean teardrop-based AAD was quite significantly different from the mean rim-based AAD due to the use of different anatomical landmarks. Teardrop-based AADs are lower than rim-based AADs, leading to measurement differences of more than 10°. CONCLUSIONS: AAD measurements considering the inferior acetabular rim can be more accurate than those considering the acetabular teardrop because the inferior rim represents the nearly hemispheric acetabulum better than does the teardrop. It is recommended to differentiate between the teardrop and the inferior acetabular rim when measuring AAD to avoid confusion regarding acetabular abduction.

There are various treatments for chronic dynamic scapholunate instability and there is still much debate about the best method of treatment. We retrospectively analysed 42 patients who had been treated by arthroscopic debridement and percutaneous pinning for chronic dynamic scapholunate instability. All patients were clinically improved without radiographic changes after surgery and were still satisfied at a mean follow-up of 68 months. Arthroscopic debridement and percutaneous pinning may be a good option for treating chronic dynamic scapholunate instability. Level of evidence: IV.

Pincer nail deformity is a severe condition in which the nail bed becomes compressed and the nail shows an overcurvature. We retrospectively analyzed 13 pincer nail deformities treated using our nail plate and bed reconstruction technique. Visual analogue scale scores, the width of nail root, width of nail tip, height of nail tip, width index, and height index were assessed before and after surgery. The overcurvature was corrected after detachment of the nail plate. The nail fold was pushed underneath the nail plate and then fixed. The width of nail tip significantly increased after surgery (p < 0.05) and was maintained during follow-up. The height of nail tip decreased after surgery (p < 0.05). This nail plate and bed reconstruction technique is a simple and quick surgical method for correcting deformities and reduces risks of complications such as skin necrosis and infection compared to other existing surgical techniques. We recommend this efficient surgical technique for the treatment of pincer nails.

BACKGROUND: There is no established principle regarding weight-bearing in conservative and operative management of fifth metatarsal base fractures. METHODS: We reviewed 86 patients with acute fifth metatarsal base fractures. Conservatively treated late or early weight-bearing patients were assigned to Group A or C, respectively. Operatively treated late or early weight-bearing patients were assigned to Group B or D, respectively. Results were evaluated by clinical union, bone resorption, and the American Orthopaedic Foot and Ankle Society (AOFAS) and Visual Analogue Scale (VAS) scores. RESULTS: All 4 groups had bone union at a mean of 6.9 weeks (range, 5.1-15.0). There were no differences between the groups in the AOFAS and VAS scores. In the early weight-bearing groups, there were fewer cases of bone resorption, and the bone unions periods were earlier. CONCLUSIONS: Early weight-bearing may help this patient population. Moreover, conservative treatment could be an option in patients with underlying diseases.

PURPOSE: To incorporate a diagnostic technique for measuring subtalar motion, namely "talar rotation", into the manual supination-anterior drawer stress radiographs for evaluation of the severity of rotational instability, and to determine its clinical relevance. METHODS: Sixty-six patients with combined injuries of the anterior talofibular (ATFL) and calcaneofibular ligament (CFL) underwent three bilateral manual stress radiographs, and mean increments of anterior talar translation (mm), talar tilt (°), and talar rotation (%) in the injured ankle compared to the normal opposite side were measured with the technique. Intraobserver and interobserver reliability of each measure was assessed, and the difference in the degree of increments was compared according to the presence of additional cervical ligament insufficiency. RESULTS: Ankle stress radiographic intraobserver and interobserver agreement was ICC = 0.91 and 0.82 for talar rotation (%), ICC = 0.64 and 0.51 for anterior talar translation, and ICC = 0.78 and 0.71 for talar tilt angle, respectively. In group 2 including patients with combined injuries of the ATFL and CFL along with additional cervical ligament insufficiency, a significantly higher increment of talar rotation, mean 6.4% (SD 3.4%), was observed compared to that of talar rotation, mean 4.1% (SD 2.7 ), in the other group (group 1) with an intact cervical ligament (p < 0.001). CONCLUSIONS: A new comprehensive stress radiographic technique for diagnosis of chronic lateral ankle instability presented in this study might be a reliable and representable measurement tool to assess additional injury or instability of the subtalar joint. LEVEL OF EVIDENCE: Prospective cohort study, Level II.

The purpose of the present study was to investigate the outcomes of distal chevron osteotomy with lateral soft tissue release for moderate to severe hallux valgus. The patients were selected using criteria that included the degree of lateral soft tissue contracture and metatarsocuneiform joint flexibility. The contracture and flexibility were determined from intraoperative varus stress radiographs. From April 2007 to May 2009, 56 feet in 51 consecutive patients with moderate to severe hallux valgus had undergone distal chevron osteotomy with lateral soft tissue release. This was done when the lateral soft tissue contracture was not so severe that passive correction of the hallux valgus deformity was not possible and when the metatarsocuneiform joint was flexible enough to permit additional correction of the first intermetatarsal angle after lateral soft tissue release. The mean patient age was 45.2 (range 23 to 54) years, and the duration of follow-up was 27.5 (range 24 to 46) months. The mean hallux abductus angle decreased from 33.5° ± 3.1° to 11.6° ± 3.3°, and the first intermetatarsal angle decreased from 16.4° ± 2.7° to 9.7° ± 2.1°. The mean American Orthopaedic Foot and Ankle Society hallux-interphalangeal scores increased from 66.6° ± 10.7° to 92.6° ± 9.4° points, and 46 of the 51 patients (90%) were either very satisfied or satisfied with the outcome. No recurrence of deformity or osteonecrosis of the metatarsal head occurred. When lateral soft tissue contracture is not severe and when the metatarsocuneiform joint is flexible enough, distal chevron osteotomy with lateral soft tissue release can be a useful and effective choice for moderate to severe hallux valgus deformity.

Fixation of a large osteochondral fragment on the posteromedial talus can be performed using medial malleolar osteotomy or an arthroscopic technique with a transmalleolar portal. However, osteotomy can be associated with some morbidity, such as longstanding pain and tenderness at the osteotomy site. Also, it requires longer immobilization. However, the transmalleolar portal damages the tibial articular cartilage, which can later cause pain. In young patients, it can injure the epiphyseal plate. We describe a posterior arthroscopic technique using 3 posterior portals that allow access to a posteromedial osteochondral lesion of the talus and fixation of the osteochondral fragment without malleolar osteotomy or transmalleolar drilling.

OBJECTIVE: The aim of this study was to evaluate the results of interpositional arthroplasty with tensor fascia lata or fat as a treatment for traumatic subtalar joint arthritis after a fracture of the calcaneus. METHODS: From August 2006 to March 2008, 22 patients with traumatic subtalar joint arthritis were enrolled in this study. Tensor fascia lata was implanted for 7 patients who previously underwent surgery with the extensive lateral approach. Fat was implanted for 15 patients who were previously managed with conservative or percutaneous fixation. All the patients were followed up for more than 1 year, and the results were evaluated retrospectively. RESULTS: The Ankle-Hindfoot score by the American Orthopedic Foot & Ankle Society changed from 60.95 to 80.23 (p < 0.05). Visual Analogue Scale pain score decreased from 6.6 to 3.8 (p < 0.05). The results of the circle draw test were excellent in 8 patients, good in 11, and fair in 3 patients without any poor outcomes. The subjective satisfaction of the patients was excellent in 16 patients, good in 4 patients, and poor in 2 patients. In 2 patients with poor satisfaction, symptoms and mobility showed no improvement postoperatively. CONCLUSIONS: Interpositional arthroplasty with tensor fascia lata or fat as a treatment modality of traumatic subtalar joint arthritis could provide good clinical outcome and preservation of range of motion.

PURPOSE: The purpose of this study was to evaluate the effectiveness of arthroscopy combined with hardware removal for chronic pain after satisfactory healing of an ankle fracture. We hypothesized that combining hardware removal with arthroscopy for the intra-articular pathology would improve residual complaints more so than hardware removal alone. METHODS: The outcomes of the 53 young male patients with chronic pain after healed ankle fracture treated with two different therapeutic plans: (1) conservative treatment after hardware removal (group A) and (2) arthroscopic intervention with hardware removal (group B) were prospectively studied. Patients were reviewed preoperatively and 6 and 12 months postoperatively using American Foot and Ankle Society (AOFAS) scale. RESULTS: Median AOFAS scores improved from 74 (66-80) points to 76 (73-92) points in group A and from 75 (64-80) points to 85 (72-100) points in group B, and this improvement was significantly higher for patients in group B (p = 0.001). CONCLUSIONS: This study supports the notion that when there is a definite diagnosis such as loose body, bony impingement, or anterolateral soft-tissue impingement causing chronic pain after healed ankle fracture, arthroscopic treatment with hardware removal is a better treatment option than hardware removal and conservative treatment.

The purpose of this study was to present the results of the metatarsal fractures treated with a closed antegrade intramedullary pinning technique. The records of 35 consecutive patients with metatarsal fractures operated on from August 2005 to June 2010 by the authors were retrospectively reviewed. Four patients were not contactable and 1 patient refused to participate. Accordingly, the study cohort was composed of 30 patients (24 male, 6 female) with 46 metatarsal head, neck, or shaft fractures. Inclusion criteria were metatarsal head, neck, or shaft fractures with a displacement of more than 3 to 4 mm or an angulation of more than 10° in the sagittal plane. Fractures combined with Lisfranc injury or metatarsal base fractures were excluded, as were bicortical comminuted fractures or long oblique fractures. Times to bone union, limitations of motion at affected metatarsophalangeal joints, and residual pain were evaluated at 6 weeks after surgery and at final follow-up. American Orthropedic Foot and Ankle Society scale was evaluated at final follow-up. Fracture union was obtained at an average of 7.1 (range 6 to 10) weeks. Two patients had moderate limitation of metatarsophalangeal joint at 6 weeks but recovered to full range at final follow-up. Average American Orthropedic Foot and Ankle Society score at final follow-up was 96.7 (range 83 to 100) points. Closed antegrade intramedullary pinning was found to be a useful method for treating displaced metatarsal fractures and to allow immediate joint motion and partial weightbearing in a stiff-soled shoe.

BACKGROUND: To report the treatment results of 12 patients who underwent a total excision of intradural extramedullary tumors. METHODS: Twelve cases of histopathologically confirmed intradural extramedullary tumors were treated surgically between February 2002 and March 2005. There were 8 males and 4 females with an average age of 42.6 years. The mean postoperative follow-up period was 24.2 months. The histopathological findings, locations of the tumors, and clinical results were analyzed. The neurological findings obtained during the preoperative stage and the postoperative follow-up were evaluated according to the Frankel classification. RESULTS: The histopathological results are as follows: 4 cases of a meningioma, 4 cases of a schwannoma, 2 cases of an epidermoid cyst, 1 case of an arachnoid cyst, and 1 case of an ependymoma. The locations of the tumors were as follows: 7 cases in the thoracic region, 4 cases in the lumbar region, and 1 case in the cervical region. At the final follow-up, a 2-grade and 1-grade improvement was observed in 1 and 7 cases, respectively. There were no changes in the Frankel grade in 4 cases. The preoperative neurological deficit improved within 8 postoperative weeks in most cases and within 1 postoperative year in all cases. Postoperatively, there were 2 cases of cerebrospinal fluid leakage and 2 cases of paresthesia. CONCLUSIONS: Intradural extramedullary tumors detected by MRI are mostly benign and good clinical results can be obtained when treated surgically. Therefore, more active surgical approaches by orthopedic surgeons are recommended to decrease morbidity.
