INTRODUCTION
The Proximal Tibiofibular Joint (PTFJ) is a synovial joint with anatomical variations located between the anteromedial surface of the fibula and the posterolateral facet of the tibia. These anatomical variations are believed to contribute to different biomechanical behaviors in both the knee and ankle joint and play a role in both physiological and pathological movements. Therefore, the morphology of the proximal tibiofibular joint may play a decisive role in the characteristics of ankle fractures and syndesmotic ligament injuries.
MATERIALS AND METHODS
In this retrospective comparative our CT database was searched between January 2015 and December 2022. Following inclusion criteria were used: Availability of knee CT scans for the fractured ankle, external rotation-type injuries (pronation external rotation and supination external rotation fractures). After applying the exclusion criteria (Plafond fractures, supination adduction and pronation abduction type fractures, pathological fractures, patients with previous fractures or surgeries around the knee, patients with previous fractures or surgeries around the knee, proximal tibiofibular arthrosis), 44 CT scans (mean age = 42.8 ± 14.1) confirmed eligible for further analysis. On each scan following measurements were performed: Coronal and sagittal PTFJ inclination angle, Joint obliquity, fibula head-tibia joint distance and tibia plateau-fibular axis angle.
RESULTS
The study consisted of 24 (54.5 %) male and 20 (45.5 %) female patients. According to the proximal fibular inclination, 29 cases (65.9 %) were of the oblique type, and 15 cases (34.1 %) were of the horizontal type. The distribution of PTFJ variations was as follows: 17 (38.6 %) concave, 4 (9.1 %) convex, 7 (15.9 %) atypical, and 16 (36.4 %) flat type. Regarding the PTFJ joint contour, the distribution was 13 (29.5 %) type a, 11 (25 %) type b, and 20 (45.5 %) type c. There was no relationship between measurements of PITFJ morphology and the type of ankle fracture and/or syndesmosis injury (p > 0.05).
CONCLUSION
PTFJ morphological features are not associated with rotational ankle fractures and syndesmotic ligament injuries.

Meta-Analysis Comparative Study
BACKGROUND
Despite fractures of Isolated Weber B being prevalent, there is a lack of clarity regarding the relative effectiveness of surgical versus conservative treatment. This systematic review and meta-analysis aimed to investigate the clinical effects and complications of surgical versus conservative treatment of the Isolated Weber B ankle fractures.
METHODS
This study involved thorough searches across multiple electronic databases, including PubMed, Cochrane, Embase, and Web of Science, to identify all relevant publications on Isolated Weber B ankle fractures repaired through surgical versus conservative treatment. Through a comprehensive meta-analysis, several outcomes were evaluated, including post-operative function, complications and reoperation rate.
RESULT
Six articles involving 818 patients who met the inclusion criteria. Among these participants, 350 were male and 636 were female. 651 patients received conservative treatment, while 396 underwent surgical intervention. The findings indicate no significant differences in OMAS, FAOQ, PCS, MCS scores, and return to work between surgical and non-surgical treatments for isolated Weber B ankle fractures. However, compared with surgical treatment, non-surgical treatment has a higher AOFAS score(MD = -5.31, 95% CI = [-9.06, -1.55], P = 0.20, I = 39%), lower VAS score(MD = 0.72, 95% CI = [0.33, 1.10], P = 0.69, I = 0%), lower complication rate (RR = 3.06, 95% CI = [1.58, 6.01], P = 0.05, I = 54%), and lower reoperation rate(RR = 8.40, 95% CI = [1.57, 45.06], P = 0.05, I = 67%).

Weber Type B fractures often arise from external rotation with the foot supinated or pronated. Altered tibiofibular joint kinematics in Weber B fractures are responsible for syndesmotic damage seen in Weber B fractures. Weber B fractures are managed using open reduction and internal fixation if displaced. The syndesmosis is injured in up to 40% of cases resulting in an unstable injury with a syndesmotic diastasis. This systematic review aimed to evaluate the current literature on syndesmotic fixation in Weber B fractures, assess the outcomes and complications of syndesmotic fixation and assess the necessity of syndesmotic fixation in Weber B fractures. A search was carried out on the EMBASE, PubMed and CINAHL databases and eight studies assessing the outcomes of syndesmotic fixations versus no syndesmotic fixation with 292 Weber B ankle fractures were included in this systematic review. Results showed significant heterogeneity so a narrative review was conducted. Results of these studies showed that functional, radiological, and quality-of-life outcomes and incidences of post-traumatic osteoarthritis in patients with syndesmotic screws were similar to those of patients not managed with syndesmotic screws. Only one favoured syndesmotic fixation in all cases of diastasis. As such, syndesmotic fixation with screws may not be necessary in the management of Weber B fractures. Screws are also associated with breakage, loosening, local irritation and infections. Suture button devices and antiglide fixation techniques appear to be valid alternatives to syndesmotic screws. It was found that there was no need for routine hardware removal unless the hardware was causing significant side effects for the patient.

INTRODUCTION
The risk of falls among the elderly significantly increases, which has become a serious public health concern. Falls can not only lead to serious complications such as fractures and brain injuries but also limit their mobility function, reducing quality of life. Foot intrinsic muscles (FIMs) are an essential part of foot core stability even overall postural stability. This study aimed to investigate the effects of aging on the function of FIMs and to explore the influence of FIMs on postural control in the elderly.
MATERIALS AND METHODS
56 healthy old participants (60-75 years) and 57 healthy young participants (18-29 years) joined this study. An ergoFet dynamometer was used to determine foot muscle strength (Doming, T, T and T), and ankle muscle strength (plantarflexion and dorsiflexion). The morphology of FIMs and extrinsic foot muscle was determined using a Doppler ultrasound system, whereas the postural stability was assessed through Limits of Stability test. Independent samples -test was used to determine the differences in strength and morphological parameters and Spearman correlation analysis was used to determine whether an association existed between muscle strength and postural stability parameters in the elderly.
RESULTS
Compared with young adults, foot muscle strength and ankle muscle strength (Doming, T, T, T, dorsiflexion, and plantarflexion, all p <0.05) and the morphology of foot muscles (all p <0.05) were significantly reduced in the elderly. The strength of FIMs and the limit of stability (r = 0.302-0.424, all p <0.05) were significantly correlated in the elderly.
CONCLUSION
Compared with young adults, the weakness of strength as well as the morphological decline of the intrinsic and extrinsic foot muscles were found in the elderly. In addition, a correlation was observed between FIM's strength and postural stability in the elderly, suggesting their potential role in posture stability.

BACKGROUND
Femoral and tibial fractures may result in delayed union and nonunion, posing significant challenges in orthopedic practice. The Ilizarov technique has emerged as a promising solution for managing these complex cases.
OBJECTIVES
Evaluate the radiographic and functional results of Ilizarov fixation in the treatment of nonunion of tibia and femur fractures.
DESIGN
Retrospective.
SETTINGS
Hospitals affiliated with a university hospital.
PATIENTS AND METHODS
Patient demographics, fracture characteristics, and treatment details were analyzed for the period from October 2015 to September 2022 in patients who were treated for nonunion of the tibia and femur using the Ilizarov fixator. Clinical and radiological assessments were performed using the Association for the Study and Application of Methods of Ilizarov (ASAMI) criteria. The study focused on assessing the average duration for union and frame removal, bone results, successful union rates, and functional results using the ASAMI criteria, obtaining data from the existing medical records, spanning various medical facilities treating nonunion fractures.
SAMPLE SIZE
126 patients.
RESULTS
The average duration for union and frame removal was 8 months, with excellent bone results observed in 60.32% of cases. Out of 126 patients, 118 achieved successful union, while there were 2 failure cases necessitating amputation (1.52%). Functional results revealed excellent outcomes in 39.68% of cases. Complications included pin tract infections, ankle and knee stiffness, and limb shortening. External fixation duration and infection eradication were consistent with previous research, emphasizing the technique's effectiveness.
CONCLUSIONS
The Ilizarov technique proved highly effective in managing nonunion tibia and femur fractures, offering favorable outcomes in terms of union, infection control, pain relief, and functional recovery. While excellent bone outcomes do not guarantee optimal function, this method remains a reliable approach for complex cases.
LIMITATIONS
Potential biases inherent in retrospective analyses and the need for further randomized controlled trials to comprehensively compare treatment modalities.

BACKGROUND
Fifth metatarsal basis fractures are common injuries. Zone 1 fractures are also known as pseudo-jones fractures. This study aimed to elucidate the impact of foot radiologic morphology on pseudo-Jones fractures.
METHODS
Patients with pseudo-Jones fractures formed the case group and individuals with ankle sprains but no fractures formed control group. Weight-bearing anteroposterior and lateral radiographs were evaluated for pre-determined measurements: metatarsus adductus angle (MAA), intermetatarsal angles (1-2, 4-5), calcaneal inclination (CI) angle, and fifth metatarsal base angle. All measurements were performed by a single investigator using digital PACS tools. Statistical analysis compared these radiographic parameters between the groups.
RESULTS
The fracture group demonstrated a significantly lower 4-5 intermetatarsal and calcaneal inclination angles than the control group (p < 0.05). Notably, no statistically significant difference was found in the metatarsus adductus angle.
CONCLUSION
This study demonstrates a potential association between foot radiographic morphology and pseudo-Jones fractures. Patients with a lower 4-5 IMA and calcaneal inclination angle may be at a higher risk for developing pseudo-Jones fractures. However, these requires future prospective studies.

BACKGROUND
Primary arthrodesis of Lisfranc fracture-dislocations is a reliable treatment option, yet concerns remain about nonunion. Nitinol staple use has recently proliferated in midfoot arthrodesis. The purpose of this study is to examine the union rate of primary arthrodesis of acute Lisfranc fracture-dislocations treated with nitinol staples compared with traditional plate-and-screw fixation. The secondary objective is to assess the difference in operative times and reoperation rates.
METHODS
Midfoot fracture-dislocations treated with primary arthrodesis by 7 foot and ankle orthopaedic surgeons were reviewed. Of 160 eligible patients, 121 patients (305 joints) met the required 4-month minimum radiographic follow-up. Radiographic outcomes were analyzed at the individual joint level. Each joint was classified as either staples alone (45 patients, 154 joints), staples plus plates and screws (hybrid) (45 patients, 40 joints), or plates and screws alone (31 patients, 111 joints). The primary outcome was arthrodesis union at each joint fused.
RESULTS
Nonunion was more common (9.0%, 10/111) among joints fixed with plate and screws than with hybrid (2.5%, 1/40) or staples only (1.3%, 2/154) ( = .0085). Multivariable regression demonstrated that autograft use was independent associated with union ( = .0035) and plate-and-screw only fixation was an independent risk factor for nonunion ( = .0407). Median operating room and tourniquet times were shorter for hybrid (92 and 83 minutes) and staple only (67 and 63 minutes) constructs compared to plate-and-screw only fixation (105 and 95 minutes) ( .0001 and .0003). There was no difference in reoperation rates among patients with different fixation types.
CONCLUSION
We found that use of nitinol compression staple and bone autograft in primary arthrodesis of Lisfranc and midfoot fracture-dislocations was associated with both improved union rates and shorter tourniquet and operative times compared to traditional plate-and-screw fixation techniques.

BACKGROUND
After surgery for a broken ankle, patients are usually instructed to avoid walking for 6 weeks (delayed weight-bearing). Walking 2 weeks after surgery (early weight-bearing) might be a safe and preferable rehabilitation strategy. This study aimed to determine the clinical and cost effectiveness of an early weight-bearing strategy compared with a delayed weight-bearing strategy.
METHODS
This was a pragmatic, multicentre, randomised, non-inferiority trial including 561 participants (aged ≥18 years) who received acute surgery for an unstable ankle fracture in 23 UK National Health Service (NHS) hospitals who were assigned to either a delayed weight-bearing (n=280) or an early weight-bearing rehabilitation strategy (n=281). Patients treated with a hindfoot nail, those who did not have protective ankle sensation (eg, peripheral neuropathy), did not have the capacity to consent, or did not have the ability to adhere to trial procedures were excluded. Neither participants nor clinicians were masked to the treatment. The primary outcome was ankle function measured using the Olerud and Molander Ankle Score (OMAS) at 4 months after randomisation, in the per-protocol population. The pre-specified non-inferiority OMAS margin was -6 points and superiority testing was included in the intention-to-treat population in the event of non-inferiority. The trial was prospectively registered with ISRCTN Registry, ISRCTN12883981, and the trial is closed to new participants.
FINDINGS
Primary outcome data were collected from 480 (86%) of 561 participants. Recruitment was conducted between Jan 13, 2020, and Oct 29, 2021. At 4 months after randomisation, the mean OMAS score was 65·9 in the early weight-bearing and 61·2 in the delayed weight-bearing group and adjusted mean difference was 4·47 (95% CI 0·58 to 8·37, p=0·024; superiority testing adjusted difference 4·42, 95% CI 0·53 to 8·32, p=0·026) in favour of early weight-bearing. 46 (16%) participants in the early weight-bearing group and 39 (14%) in the delayed weight-bearing group had one or more complications (adjusted odds ratio 1·18, 95% CI 0·80 to 1·75, p=0·40). The mean costs from the perspective of the NHS and personal social services in the early and delayed weight-bearing groups were £725 and £785, respectively (mean difference -£60 [95% CI -342 to 232]). The probability that early weight-bearing is cost-effective exceeded 80%.
INTERPRETATION
An early weight-bearing strategy was found to be clinically non-inferior and highly likely to be cost-effective compared with the current standard of care (delayed weight-bearing).

Nonphysician Evaluators and Recording-Based Tools in Surgical Skill Assessment: A Feasibility Study.Journal of Surgical Education Jun 2024To investigate the feasibility of nonmedically trained evaluators and image- and video-based tools in the assessment of surgical skills in a key orthopedic procedure.
OBJECTIVES
To investigate the feasibility of nonmedically trained evaluators and image- and video-based tools in the assessment of surgical skills in a key orthopedic procedure.
DESIGN
Orthopedic surgeons at varying skill levels were evaluated by their ability to repair a cadaveric bi-malleolar ankle fracture. Nonphysician viewers and expert orthopedic surgeons independently scored video recordings and fluoroscopy images of the procedure through Global Rating Scales (GRS) and procedure-specific checklist tools. Statistical analysis was used to determine if the evaluators and assessment tools were able to differentiate skill level.
SETTING
An academic tertiary care hospital.
PARTICIPANTS
The surgical procedure was completed by 3 orthopedic residents, 3 orthopedic trauma fellows, and 4 orthopedic trauma attending surgeons. The procedure was independently evaluated by 2 orthopedic surgeons and 2 nonphysicians.
RESULTS
Operating participants were stratified by ≤ or >10 bimalleolar ankle fracture cases performed alone (inexperienced, n = 5 vs experienced, n = 5). Expert surgeon viewers could effectively stratify skill group through the GRS for video and fluoroscopy analysis (p < 0.05), and the video procedure-specific checklist (p < 0.05), but not the fluoroscopy procedure-specific checklist. Nonphysician viewers generally recognized skill groupings, although with less separation than surgeon viewers. These evaluators performed the best when aided by video and fluoroscopy procedure-specific checklists. Meanwhile, breakdowns of each tool into critical zones for improvement and evaluator-independent metrics such as case experience, self-reported confidence, and surgical time also indicated some skill differentiation.
CONCLUSIONS
The feasibility of using video recordings and fluoroscopic imaging based surgical skills assessment tools in orthopedic trauma was demonstrated. The tools highlighted in this study are applicable to both cadaver laboratory settings and live surgeries. The degree of training that is required by the evaluators and the utility of measuring surgical times of specific tasks should be the subject of future studies.
