INTRODUCTION
Ankle arthrodesis is a crucial surgical intervention for advanced hindfoot conditions, aiming to restore plantigrade walking and alleviate pain. This study evaluates the effectiveness of a specific surgical approach for tibiotalocalcaneal arthrodesis (TTCA), focusing on rigorous risk factor control, corticocancellous grafting, and internal fixation using an angled retrograde femoral nail in the sagittal plane, and assesses the outcomes of this approach in terms of bone fusion and reduction of postoperative complications.
MATERIALS AND METHODS
This retrospective analysis includes 17 patients who underwent TTCA in a trauma-orthopedic department over seven years. Data were collected from medical records, the HOSIX software, and patient consultations. Preoperative assessments, surgical techniques, postoperative care, and follow-up evaluations were documented.
RESULTS
The mean age of patients was 42.4 years, with a male predominance. Surgical indications included post-traumatic arthropathy (53%), inflammatory arthropathy, ankle infectious pathologies, and Charcot foot and ankle prosthesis failures. All patients underwent standard preoperative evaluations and received corticocancellous grafts. An angled retrograde femoral nail in the sagittal plane was used for internal fixation. Postoperative immobilization lasted 6 to 8 weeks, with subsequent rehabilitation. The bone fusion rate was 100%, with a low complication rate (23.5%).
DISCUSSION
Our study showed a younger patient population with a male predominance, different from some previous studies. Surgical techniques, including the anterior approach combined with a lateral subtalar approach, were consistent with some studies but differed from others. Corticocancellous grafts and the angled retrograde femoral nail in the sagittal plane demonstrated favorable outcomes in terms of fusion. Complication rates were lower compared to some previous reports, highlighting potential improvements in postoperative management.
CONCLUSION
The surgical approach described for TTCA, emphasizing rigorous risk factor control, corticocancellous grafting, and internal fixation using an angled retrograde femoral nail in the sagittal plane, led to satisfactory bone fusion and reduced postoperative complications. These results underscore the importance of this approach in achieving optimal functional outcomes in ankle arthrodesis.

INTRODUCTION
Ankle arthrodesis is one of the treatments of choice, particularly in late-stage and unstable diabetic Charcot arthropathy. Unfortunately, poor healing capacity might play a role in the high nonunion rate (10-40%). The advancement in regenerative medicine opens a new horizon for enhancing fusion after ankle arthrodesis in patients with poor healing capacity. However, a suitable small animal model is warranted to study the effectivity of these regenerative medicine approaches. Streptozotocin (STZ)-induced diabetes models and adjuvant-induced arthritis models with complete Freund's adjuvant are two established models. However, no study has combined those two models to make a diabetic arthritic model that more closely resembles the condition in Charcot arthropathy.
METHODS
Twenty male Sprague-Dawley rats were assigned into five groups, consisting of one control group, and four diabetic groups which were induced by STZ injection and a high-fat diet. Among these diabetic rats, two groups received complete Freund's adjuvant (CFA) injections to the left ankle of the hind limb. The control group, one of the diabetic-only groups, and one of the arthritic-diabetic-induced groups were euthanized at 4 weeks after STZ induction, and the remainder were euthanized 6 weeks after STZ induction. Clinical, radiological, and histological examinations were then compared in all five groups.
RESULTS
Diabetic status was successfully achieved in the model, which was maintained until the completion of the study. The CFA-induced ankles were significantly larger than the contralateral ankles in all groups (p<0.05). Histopathological evaluation confirmed arthritic changes in the CFA-induced group with less variability after 4 weeks of arthritis induction.
CONCLUSION
This rat model of arthritic diabetic mimics the progressive and chronic nature of Charcot arthropathy in humans. This model can be further use to study treatments that might enhance the fusion rate in ankle arthrodesis in healing-defective patients such as those with diabetes.

PURPOSE
End-stage ankle arthrosis causes severe pain and limited movement. Tibiotalocalcaneal arthrodesis with arthroscopy-assisted hindfoot nailing can be used to achieve a high union rate and low complication rate. We aimed to examine the early- and mid-term results of patients treated with this technique from various perspectives and to evaluate them by comparing them with the current literature.
METHODS
Data were collected from 25 patients who met the established criteria and underwent TTCA with arthroscopic-assisted hindfoot nailing. In addition to the demographic data of the patients, their clinical and pain scores were evaluated using the American Orthopedic Foot and Ankle Society (AOFAS) and visual analogue scale (VAS). Additionally, the union time and complication data during the follow-up period were examined.
RESULTS
When the AOFAS and VAS scores of the 25 patients were examined, a significant improvement was observed in the preoperative period and early postoperative period comparisons ( < .001). No significant change was observed between the comparison of the postoperative 12th month and last postoperative control clinical scores. While the union rate of the patients was observed to be 92%, the average union time was 13.1 ± 3.5 weeks. During follow-up, peri-implant fracture, deep infection, and non-union were observed in one patient each (12%).
CONCLUSION
The early- and mid-term postoperative results of patients treated with TTCA surgery with posterior approach arthroscopic-assisted hindfoot nailing show that this technique may be an option with low complication and high union rates for the appropriate group of patients planned for ankle arthrodesis.

Comparative Study
Posterior lumbar interbody fusion (PLIF) is widely used to treat degenerative spondylolisthesis because it provides definitive decompression and fixation. Although it has several advantages, it has some disadvantages and risks, such as paraspinal muscle injury, potential intraoperative bleeding, postoperative pain, hardware failure, subsidence, and medical comorbidity. Lumbar decompressive bilateral laminectomy with interspinous fixation (DLISF) is less invasive and can be used on some patients with PLIF, but this has not been reported. To compare the efficacy and safety of DLISF in the treatment of low-grade lumbar spondylolisthesis with that of PLIF. We retrospectively analyzed the medical records of 81 patients with grade I spondylolisthesis, who had undergone PLIF or DLISF and were followed up for more than 1 year. Surgical outcomes, visual analog scale, radiologic outcomes, including Cobb angle and difference in body translation, and postoperative complications were assessed. Forty-one patients underwent PLIF, whereas 40 underwent DLISF. The operative times were 271.0 ± 57.2 and 150.6 ± 29.3 minutes for the PLIF and DLISF groups, respectively. The estimated blood loss was significantly higher in the PLIF group versus the DLISF group (290.7 ± 232.6 vs 122.2 ± 82.7 mL, P < .001). Body translation did not differ significantly between the 2 groups. Overall pain improved during the 1-year follow-up when compared with baseline data. Medical complications were significantly lower in the DLISF group, whereas perioperative complications and hardware issues were higher in the PLIF group. The outcomes of DLISF, which is less invasive, were comparable to PLIF outcomes in patients with low-grade spondylolisthesis. As a salvage technique, DLISF may be a good option when compared with PLIF.

BACKGROUND AND PURPOSE
There is conflicting evidence regarding treatment outcomes after minimally invasive sacroiliac joint fusion for long-lasting severe sacroiliac joint pain. The primary aim of our cohort study was to investigate change in patient-reported outcome measures (PROMs) after minimally invasive sacroiliac joint surgery in daily practice in the Swedish Spine Registry. Secondary aims were to explore the proportion of patients reaching a patient acceptable symptom score (PASS) and the minimal clinically important difference (MCID) for pain scores, physical function, and health-related quality of life outcomes; furthermore, to evaluate self-reported satisfaction, walking distance, and changes in proportions of patients on full sick leave/disability leave and report complications and reoperations.
METHODS
Data from the Swedish Spine Registry was collected for patients with first-time sacroiliac joint fusion, aged 21 to 70 years, with PROMs available preoperatively, at 1 or 2 years after last surgery. PROMs included Oswestry Disability Index (ODI), Numeric Rating Scale (NRS) for low back pain (LBP) and leg pain, and EQ-VAS, in addition to demographic variables. We calculated mean change from pre- to postoperative and the proportion of patients achieving MCID and PASS.
RESULTS
68 patients had available pre- and postoperative data, with a mean age of 45 years (range 25-70) and 59 (87%) were female. At follow-up the mean reduction was 2.3 NRS points (95% confidence interval [CI] 1.6-2.9; P < 0.001) for LBP and 14.8 points (CI 10.6-18.9; P < 0.001) for ODI. EQ-VAS improved by 22 points (CI 15.4-30.3, P < 0.001) at follow-up. Approximately half of the patients achieved MCID and PASS for pain (MCID NRS LBP: 38/65 [59%] and PASS NRS LBP: 32/66 [49%]) and physical function (MCID ODI: 27/67 [40%] and PASS ODI: 24/67 [36%]). The odds for increasing the patient's walking distance to over 1 km at follow-up were 3.5 (CI 1.8-7.0; P < 0.0001), and of getting off full sick leave or full disability leave was 0.57 (CI 0.4-0.8; P = 0.001). In the first 3 months after surgery 3 complications were reported, and in the follow-up period 2 reoperations.
CONCLUSION
We found moderate treatment outcomes after minimally invasive sacroiliac joint fusion when applied in daily practice with moderate pain relief and small improvements in physical function.

Chronic unreduced dislocations of the proximal interphalangeal joint are uncommon, and management principles for these injuries have not been defined. The dislocation can be volar or dorsal and closed reduction is rarely successful owing to soft tissue contractures. Treatment options in literature reviews for such rare injuries included open reduction of pip joint with volar plate arthroplasty, extension block pinning, hemi hamate arthroplasty, pip joint arthrodesis, Suzuki dynamic frame fixation, open reduction and repair of capsule and collateral ligaments with suture anchors. Few cases of amputation following treatment were even reported in literature emphasizing the role of meticulous soft tissue handling in such neglected cases of hand. We report six cases of neglected (more than three months old) dorsal dislocation of the PIP joint of the hand, treated with volar plate arthroplasty and extension block pinning. A functional range of motion with a stable joint can be achieved in such injuries with volar plate arthroplasty, as long as the articular cartilage is relatively preserved and bone loss is <30%.

Pedicle screw insertion into infected vertebrae reduces operative time and range of fixation in minimally invasive posterior fixation for thoracolumbar pyogenic spondylitis: a multicenter retrospective cohort study.
BACKGROUND
Minimally invasive posterior fixation surgery for pyogenic spondylitis is known to reduce invasiveness and complication rates; however, the outcomes of concomitant insertion of pedicle screws (PS) into the infected vertebrae via the posterior approach are undetermined. This study aimed to assess the safety and efficacy of PS insertion into infected vertebrae in minimally invasive posterior fixation for thoracolumbar pyogenic spondylitis.
METHODS
This multicenter retrospective cohort study included 70 patients undergoing minimally invasive posterior fixation for thoracolumbar pyogenic spondylitis across nine institutions. Patients were categorized into insertion and skip groups based on PS insertion into infected vertebrae, and surgical data and postoperative outcomes, particularly unplanned reoperations due to complications, were compared.
RESULTS
The mean age of the 70 patients was 72.8 years. The insertion group (n = 36) had shorter operative times (146 versus 195 min, p = 0.032) and a reduced range of fixation (5.4 versus 6.9 vertebrae, p = 0.0009) compared to the skip group (n = 34). Unplanned reoperations occurred in 24% (n = 17) due to surgical site infections (SSI) or implant failure; the incidence was comparable between the groups. Poor infection control necessitating additional anterior surgery was reported in four patients in the skip group.
CONCLUSIONS
PS insertion into infected vertebrae during minimally invasive posterior fixation reduces the operative time and range of fixation without increasing the occurrence of unplanned reoperations due to SSI or implant failure. Judicious PS insertion in patients with minimal bone destruction in thoracolumbar pyogenic spondylitis can minimize surgical invasiveness.

BACKGROUND Cervical spondylolysis with spondylolisthesis is a rare disorder. According to previous reports, the spondylolisthesis is usually Meyerding Grade I, with only a limited number of cases receiving surgical treatment. We hereby report a special case of cervical spondylolysis with Grade-II spondylolisthesis, treated with single-level anterior cervical discectomy and fusion (ACDF), and present a literature review related to this problem. CASE REPORT Here, we report the case of a 52-year-old man who complained of posterior neck pain and numbness of the bilateral upper limbs. Radiological examination showed bilateral spondylolysis of the C6 and Meyerding Grade-II spondylolisthesis of C6 on C7 with instability. The patient underwent a single-level C6/C7 ACDF surgery. The symptoms of neck pain and bilateral upper-limb numbness were relieved immediately after surgery. The immediate postoperative radiological examination showed successful restoration of sagittal alignment. At 3-month follow-up, the patient had returned to normal life without any symptoms. At 2-year follow-up, computed tomography showed that C6-C7 fusion had been achieved and alignment was maintained. CONCLUSIONS Cervical spondylolysis, as an uncommon spinal disorder, has been regarded as a congenital abnormity, and has unique radiological characteristics. For most of the cases with cervical spondylolysis, even with Grade-II spondylolisthesis, single-level ACDF can achieve good clinical and radiological outcomes.

BACKGROUND
Endoscopic spine lumbar interbody fusion (Endo-LIF) is well-regarded within the academic community. However, it presents challenges such as intraoperative disorientation, high rates of nerve damage, a steep learning curve, and prolonged surgical times, often occurring during the creation of the operative channel. Furthermore, the undefined safe operational zones under endoscopy continue to pose risks to surgical safety. We aimed to analyse the anatomical data of Kambin's triangle via CT imaging to define the parameters of the safe operating area for transforaminal posterior lumbar interbody fusion (TPLIF), providing crucial insights for clinical practice.
METHODS
We selected the L4-L5 intervertebral space. Using three-dimensional (3D), we identified Kambin's triangle and the endocircle within it, and recorded the position of point 'J' on the adjacent facet joint as the centre 'O' of the circle shifts by angle 'β.' The diameter of the inscribed circle 'd,' the abduction angle 'β,' and the distances 'L1' and 'L2' were measured from the trephine's edge to the exiting and traversing nerve roots, respectively.
RESULTS
Using a trephine with a diameter of 8 mm in TPLIF has a significant safety distance. The safe operating area under the TPLIF microscope was also clarified.
CONCLUSIONS
Through CT imaging research, combined with 3D simulation, we identified the anatomical data of the L4-L5 segment Kambin's triangle, to clarify the safe operation area under TPLIF. We propose a simple and easy positioning method and provide a novel surgical technique to establish working channels faster and reduce nerve damage rates. At the same time, according to this method, the Kambin's triangle anatomical data of the patient's lumbar spine diseased segments can be measured through CT 3D reconstruction of the lumbar spine, and individualised preoperative design can be conducted to select the appropriate specifications of visible trephine and supporting tools. This may effectively reduce the learning curve, shorten the time operation time, and improve surgical safety.

Can zoledronic acid reduce the risk of cage subsidence after oblique lumbar interbody fusion combined with bilateral pedicle screw fixation in the elderly population? A retrospective study.
BACKGROUND
The objective of this study was to evaluate the potential of zoledronic acid for reducing the incidence of cage subsidence and enhancing interbody fusion rates following oblique lumbar interbody fusion (OLIF) surgery, particularly as the first reported evidence of the role of zoledronic acid combined with OLIF.
METHODS
A retrospective analysis was conducted on data from 108 elderly patients treated for degenerative lumbar diseases using OLIF combined with bilateral pedicle screw fixation from January 2018 to December 2021. Patients were divided into the zoledronic acid (ZOL) group (43 patients, 67 surgical segments) and the control group (65 patients, 86 surgical segments). A comparative analysis of the radiographic and clinical outcomes between the groups was performed, employing univariate and multivariate regression analyses to explore the relationships between cage subsidence and the independent variables.
RESULTS
Radiographic outcomes, including anterior height, posterior height, disc height, coronal disc angle, foraminal height, and lumbar lordosis, were not significantly different between the two groups. Similarly, no statistically significant differences were noted in the back visual analog scale (VAS) scores and Oswestry Disability Index (ODI) scores between the groups. However, at the 1-year follow-up, the leg VAS score was lower in the ZOL group than in the control group (P = 0.028). The ZOL group demonstrated a notably lower cage subsidence rate (20.9%) than did the control group (43.0%) (P < 0.001). There was no significant difference in the interbody fusion rate between the ZOL group (93.0%) and the control group (90.8%). Non-use of zoledronic acid emerged as an independent risk factor for cage subsidence (OR = 6.047, P = 0.003), along with lower bone mineral density, lower postoperative anterior height, and concave endplate morphology. The model exhibited robust discriminative performance, with an area under the curve (AUC) of 0.872.
CONCLUSION
The administration of zoledronic acid mitigates the risk of cage subsidence following OLIF combined with bilateral pedicle screw fixation in elderly patients; however, it does not improve the interbody fusion rate.
