Modified arthroscopic repair of a posterior cruciate ligament tibial avulsion fracture improves IKDC and Lysholm score compared to open reduction.

PURPOSE: The purpose of this study was to analyse the difference between arthroscopic fixation and open reduction internal fixation (ORIF) of posterior cruciate ligament (PCL) tibial avulsion fractures. METHODS: This retrospective study analysed patients with an acute PCL tibial avulsion fracture who underwent surgical treatment at our hospital and follow-up for at least 24 months. Variables based on sex, age, Meyers-McKeever type, surgical method, meniscus tear, external fixation, labour or sports, Lysholm knee score, IKDC score, and KT-1000 value were also recorded. Multifactor unconditional logistic regression and Student's t test with 1:1 propensity score matching (PSM) to remove confounding factors were used for analysis. RESULTS: Sixty-five cases achieved knee function graded as "good" or better, and 9 cases not. Single-factor analysis indicated that Meyers-McKeever type (χ2 = 4.669, P = 0.031) and surgical approach (χ2 = 9.428, P = 0.002) are related to functional outcomes. Multifactorial logistic regression analysis further confirmed that Meyers-McKeever typing (OR = 10.763, P = 0.036, [95% CI 1.174-98.693]) and surgical approach (OR = 9.274, P = 0.008, [95% CI 1.794-47.934]) are independent risk factors affecting prognosis. In addition, PSM verified significant differences in the Lysholm score (t = 3.195, P = 0.006), IKDC score (t = 4.703, P = 0.000) and A-KT/H-KT (t = 2.859, P = 0.012). However, the affected-side KT-1000 value (A-KT, mm, t = 1.225, P = 0.239) and healthy-side KT-1000 value (H-KT, mm, t = 1.436, P = 0.172) did not significantly differ between the two groups. The proportions of cases in which the Lysholm score, IKDC and A-KT/H-KT exceeded the minimal clinically important difference (MCID) were 62.5% (20/32), 62.5% (20/32) and 93.75% (30/32), respectively. CONCLUSION: Compared with ORIF, an arthroscopic approach for PCL tibial avulsion fractures achieves better results. LEVEL OF EVIDENCE: Retrospective cohort study; Level II.

Posterior Cruciate Ligament Injuries in Very Young Children - A Case Report and Modern Review.

Background: Posterior cruciate ligament (PCL) tears in young children are rare and optimal treatment is poorly described. Diagnosis may prove challenging as young children may not be able to verbalize a complete history of injury, may be difficult to examine, and plane film radiographs often appear within normal limits. Surgical treatment carries a risk of physeal arrest, but non-operative treatment may lead to recurrent instability and pain. Methods: We present a case report of a fouryear- old child with a PCL avulsion off the femoral insertion who received an open reduction and internal fixation (ORIF) with combined arthroscopic synovial debridement. We performed a literature review which compared the mechanism, location, concomitant injuries, work up and management of PCL injuries in children under the age of ten compared to adolescents and adults. Results: Nineteen months following surgery, physical examination revealed full knee range of motion and return to baseline function. Imaging studies confirmed there was no evidence of physeal arrest. Conclusion: ORIF with arthroscopy can be an effective method to treat PCL avulsions in children under the age of 10 years. This is similar to other case reports which reported positive outcomes with ORIF in this population. Large studies are needed to best understand optimal treatment modalities for PCL injuries in very young children. Level of Evidence: IV.

[Comparison of open reduction hollow nail anchoring system with loop plate fixation under arthroscopy for the treatment of posterior cruciate ligament avulsion fractures].

OBJECTIVE: To compare clinical effect between open reduction and fixation with cannulated screw and threaded rivet via posteromedial approach versus arthroscopic Endobutton plate fixation in treating posterior cruciate ligament avulsion fractures. METHODS: Clinical data of 38 patients with posterior cruciate ligament avulsion fractures from July 2020 to December 2021 were analyzed retrospectively, and divided into open reduction and internal fixation group (posterior medial approach hollow anchor system fixation) and arthroscopic fixation group (Endobutton with loop plate fixation under arthroscopy). There were 20 patients in open reduction and internal fixation group, including 16 males and 4 females, aged from 26 to 74 years old with an average of (42.9±18.8) years old;13 patients on the left side and 7 patients on the right side;12 patients were classified to typeⅡand 8 patiens with type Ⅲ according to Meyers-McKeever fractures classification;14 patients were gradeⅡand 6 patients were grade Ⅲ in back drawer test. There were 18 patients in arthroscopic fixation group, including 11 males and 7 females;aged from 24 to 70 years old with an average of (53.5±13.4) years old;11 patients on the left side and 7 patients on the right side;10 patients were classified to typeⅡand 8 patiens with type Ⅲ according to Meyers-McKeever fractures classification;11 patients were gradeⅡand 7 patients were grade Ⅲ in back drawer test. Operation time, blood loss, and quality of immediate reduction were compared between two groups. Knee range of motion, knee back drawer test, and International Knee Documentation Committee(IKDC) grading, KT2000 stability evaluation and Lysholm function score of knee joint were compared at 6 months after operation. RESULTS: All patients were followed up for 8 to 16 months with an average of (12.3±1.9) months. There were no complications such as incision infection, fracture malunion or non-union, and internal fixation loosening occurred. The avulsion fractures of knee joint were reached to imaging healing standard at 6 months after operation. Operation time and blood loss in open reduction and internal fixation group were (56.4±7.1) min and (63.2±10.2) ml, while (89.9±7.4) min and (27.7±8.7) ml in arthroscopic fixation group, respectively, and had significant difference between two groups (P<0.05). There were no differences in immediate reduction quality (χ2=0.257, P=0.612), knee joint range of motion at 6 months after opertaion (t=0.492, P=0.626), knee joint rear drawer test ( χ2=0.320, P=0.572), IKDC classification of knee joint (χ2=0.127, P=0.938), KT2000 stability evaluation (χ2=0.070, P=0.791), and knee Lysholm function score (t=0.092, P=0.282) between two groups. CONCLUSION: Posterior medial approach with hollow anchoring system fixation and arthroscopic Endobutton with loop plate fixation for the treatment of posterior cruciate ligament tibial occlusion avulsion fracture could achieve satisfactory clinical results, and arthroscopic surgery has less bleeding, but also has a longer learning curve and longer operation time than traditional incision surgery. The surgeon needs to make a choice according to clinical situation of patient and their own surgical inclination.

A novel approach for anterior cruciate ligament tibial avulsion fracture: arthroscopic modified suture bridge fixation technique.

INTRODUCTION: Anterior cruciate ligament (ACL) tibial avulsion fracture is a rare injury, which usually happens in adults with traffic accidents or sports injuries. Surgery interventions are common treatment methods, they can restore knee function and help to return to normal life. In this study, we described an arthroscopic modified suture bridge fixation technique for ACL tibial avulsion fractures and explored the feasibility and therapeutic effects. MATERIALS AND METHODS: This retrospective study reviewed data from January 2020 to May 2022. Data were collected on 18 patients (10 males and 8 females) with ACL tibial avulsion fractures and underwent arthroscopic modified suture bridge fixation technique. The study analyzed surgical data about intraoperative blood loss, operation time, hospital stay, fracture healing time, and visual analog scale (VAS). Functional evaluation of the knee joint was performed using the anterior drawer test, Lysholm knee scoring scale, International Knee Documentation Committee (IKDC), and knee range of motion (ROM). RESULTS: All 18 patients were followed up between 12 and 20 months, with an average of 15.22 ± 1.96 months. The intraoperative blood loss was approximately 15-40 mL, averaging 25.78 ± 6.19 mL. The operation time was 65-85 min, with a mean of 74.89 ± 4.86 min. The hospital stay of patients was 3-5 days, with a mean of 3.89 ± 0.76 days. The mean fracture healing time was 8-12 weeks after surgery, with a mean of 9.22 ± 1.7 weeks. All incisions healed grade I without infection. There were no internal fixation failures, neurovascular injuries, and lower extremity deep venous thrombosis. The anterior drawer test was negative in all patients. At the final follow-up, the mean VAS score was 0-3, averaging 1.56 ± 0.71. The Lysholm score of the injured knee was 89-96, with an average of 92.50 ± 2.50; the IKDC score was 88-93, with an average of 90.44 ± 1.89; the knee ROM was 110-126°, with an average of 120.67° ± 4.31°. CONCLUSION: Results demonstrated that the modified suture bridge fixation technique under arthroscope could provide reliable fixation and favorable clinical effects for ACL tibial avulsion fractures. This is a simple, minimally invasive, effective, and clinically applicable surgical method for ACL tibial avulsion fracture.

X-Sens Inertial Sensor Technology-Based Rehabilitation on a Patient With Posterior Cruciate Ligament Avulsion Fracture and Shaft of Femur Fracture: A Case Report.

The posterior cruciate ligament (PCL), one of the key ligaments in the knee, serves to prevent backward movement of the tibia relative to the femur. A simultaneous occurrence of a PCL avulsion fracture and a femur shaft fracture in a pediatric patient suggests a complex orthopedic injury resulting from significant trauma to the knee and thigh area. This study describes the rehabilitation process of a 12-year-old female involved in a road traffic accident, who suffered both a midshaft femur fracture and a PCL avulsion fracture. Following surgical procedures, the patient underwent a comprehensive physiotherapy regimen utilizing X-Sens inertial sensor technology. The rehabilitation plan comprised multiple stages targeting pain alleviation, muscle strengthening, flexibility exercises, gait retraining, and balance improvement. Various interventions including contrast baths, cryotherapy, patellar mobilization, isotonic and resistance exercises, and progressive gait training were integrated across different phases of the rehabilitation program. Over subsequent follow-up periods, the patient demonstrated significant enhancements in pain management, range of motion, muscle strength, functional capabilities, and gait metrics. This case report underscores the efficacy of a systematic physiotherapy strategy incorporating advanced technology in the successful recovery from intricate lower limb fractures, underscoring the importance of prompt intervention and multidisciplinary collaboration for optimal patient outcomes.

Utilizing Suture Anchors in Addition to Screws for Treatment of Tibial Tubercle Avulsion Fracture: A Case Report.

Tibial tubercle avulsion fractures are relatively uncommon fractures commonly seen in adolescent males. The treatment goal is to restore the extensor mechanism and to repair the articular surface. Although previous surgical techniques have been mainly screws or tension band wiring, there is a certain consensus on this. However, the choice of these surgical techniques largely depends on the surgeon. In our case, we utilized a suture anchor distal to the cannulated screw. This enabled us to use a smaller screw and cover the screw head completely with the patellar tendon. Therefore, this can be an advantage in lowering the incidence of device irritation. Given the successful outcome of our technique, we may consider applying suture anchors more frequently in tibial tubercle avulsion fractures in the future.

Stepping into the Unknown: Unveiling the Rarity of PCL Fracture-Avulsions.

Tears of the posterior cruciate ligament (PCL) are rare, and avulsion fracture of the tibial attachment of the posterior cruciate ligament is even rarer. These injuries usually occur in accidents such as car crashes, causing acute pain, swelling as well as total functional impotence of the knee. Studies on the incidence of these injuries show variable results, but there appears to be an upward trend. The surgical management of PCL avulsion fracture is not clearly established, although arthroscopic techniques are becoming more popular due to their potential benefits. However, some medical centers may have limited access to these methods, thus preferring open surgery options. A case of LCP avulsion fracture in a 36-year-old female patient was reported, and surgery was successfully performed, leading to full recovery after six months with full knee mobility and posterior stability.

A Biomechanical Study of Calcaneal Tuberosity Avulsion Fracture: A Comparison Between Three-Screw Versus Two-Screw Fixation Strength.

A calcaneal tuberosity avulsion fracture constitutes a sub-group of calcaneal fractures and it poses a high risk of soft tissue compromise, necessitating urgent reduction and fixation. This fracture was commonly treated with screw fixation, and fixation failure associated with this method has been reported in the literature. In light of this, we tested and compared the strength of two-screw (2S) versus three-screw (3S) fixations, where the third screw was fixed from the posterior calcaneal tuberosity towards the anterior process in addition to the two parallel screws. Synthetic calcaneum models were tested with an Instron machine to measure the maximum tensile load and stiffness. The mean maximum tensile loads for 3S and 2S were 455.8 N (SD = 47.4) and 341.0 N (SD = 30.9), respectively, and the difference was statistically significant. The mean stiffnesses for 3S and 2S were 29.2 N/mm (SD = 1.8) and 29.7 N/mm (SD = 2.0), but this difference did not reach statistical significance. Based on our findings, the added third screw increased the pull-out strength and can be inserted percutaneously to minimize soft tissue compromise.

Tibial tubercle avulsion fracture following preexisting Osgood-Schlatter disease in an adolescent: a case report.

Tibial tubercle avulsion fractures (TTAFs) are rare but typical in children and adolescents and Osgood-Schlatter disease (OSD) may be involved in their pathogenesis. However, few publications have reported the relationship between OSD and TTAF. A 16-year-old healthy male adolescent presented with pain, swelling and limited range of motion of the right knee following sudden acceleration while running. Based on the radiographic evidence, the patient was diagnosed with an avulsion fracture of the right tibial tubercle and OSD. Open reduction and internal fixation were performed using two cannulated screws and two Kirschner wires. The patient returned to preinjury activity levels at the 12-month follow-up postoperatively. This case report aimed to highlight this unique injury pattern. For patients with TTAFs, not only should the fracture be treated, but the cause of the fracture, such as OSD, should also be given appropriate treatment.

Triceps Tendon Reattachment Using Mini Plates and Screws After Failure of Olecranon Avulsion Fracture Fixation in Osteoporotic Bone: A Case Report.

This is a case report of an 85-year-old woman with osteopenia who underwent olecranon avulsion fracture repair with supplemental triceps tendon repair following a fall on an outstretched arm. The initial procedure failed due to osteoporotic bone quality and an atraumatic disruption of the olecranon fracture fixation. The patient subsequently underwent further surgical intervention with an olecranon avulsion fracture excision and a novel triceps tendon repair technique using plate augmentation and fiber tape. Surgeons may consider this novel approach as an initial treatment for elderly patients with osteopenia or osteoporosis undergoing olecranon avulsion fracture fixation, to prevent the failure and consequent revision surgery.

Endoscopic Assisted Percutaneous Fixation of Anterior Inferior Iliac Spine Avulsion Fracture, Surgical Technique.

Avulsion fractures of the anterior inferior iliac spine rarely occur in adolescent athletes during rectus femoris contractions or eccentric muscle lengthening while the growth plate is still open. Currently, there are no official guidelines in the literature on the treatment indications of this type of fracture or the type of surgical technique to be used. Nowadays, young and athletic patients desire a quick return to their previous activities, which makes surgical treatment a reasonable choice. Open reduction and internal fixation with an anterior approach are usually recommended when the avulsion fragment has more than 1.5-2 cm displacement on plain radiographs. However, ORIF is associated with a higher risk of heterotopic ossifications and increases the risk of damage to the LFCN. An endoscopic technique was designed to reduce these complications. This technical note describes a procedure of percutaneous fixation to AIIS through 3 endoscopic portals that could potentially minimize complications associated with an open surgical dissection, allowing anatomic reduction under direct visualization.

Shoulder Pain in a Pediatric Throwing Athlete.

Pediatric avulsion fractures most commonly occur at sites of secondary ossification and are often associated with chronic stress from repetitive movements. Because of a variety of risk factors, youth athletes place higher stress on ossification centers, and their activities may predispose them to injury. This case report describes a 12-year-old female softball player who presented with pain at the distal acromion, worsened by her overhead throwing motion. Further questioning revealed improper throwing mechanics placing extenuated stress on the shoulder. Plain radiograph imaging showed an avulsion fracture of the distal acromion; conservative management with decreased mobilization and cessation of activity was recommended. Reimaging four weeks later revealed a bone-on-bone healing, and the patient was gradually allowed to return to function. This report's discussion details the unusual location for a common injury, the mechanism of injury, an association of throwing mechanics with a shoulder injury, and recommended treatment strategies for pediatric avulsion fractures.

[Arthroscopic suspension fixation with Endobutton in treatment of tibial insertion avulsion fractures of posterior cruciate ligament].

Objective: To investigate the effectiveness of arthroscopic suspension fixation with Endobutton in the treatment of tibial insertion avulsion fractures of posterior cruciate ligament (PCL). Methods: A retrospective analysis was conducted on the clinical data of 52 patients (52 knees) with tibial insertion avulsion fractures of PCL, who were treated by arthroscopic suspension fixation with Endobutton between June 2017 and October 2022. There were 29 males and 23 females, with an average age of 40.6 years (range, 19-66 years). There were 24 cases of traffic accident injuries, 17 cases of sports injuries, and 11 cases of fall injuries. The time from injury to operation ranged from 6 to 19 days (mean, 13.3 days). According to the Meyers-McKeever classification, there were 30 cases of type Ⅱ and 22 cases of type Ⅲ fractures. All patients exhibited positive posterior drawer test results. Preoperative knee joint function was assessed with Lysholm score (21.3±6.7), International Knee Documentation Committee (IKDC) score (20.7±5.8), and visual analogue scale (VAS) score (5.3±0.7); and knee joint range of motion was (41.73±3.17)°. Based on preoperative CT three-dimensional reconstruction measurements, the longitudinal diameter of the avulsed bone fragment ranged from 13 to 25 mm (mean, 18.1 mm). Operation time and occurrence of complications were recorded, and postoperative imaging was used to assess fracture healing. Knee joint function and pain severity were evaluated using knee joint range of motion, Lysholm score, IKDC score, and VAS score. Results: The operation time ranged from 46 to 81 minutes (mean, 56.2 minutes). All patients were followed up 12-28 months (mean, 20.1 months). The iatrogenic fractures of bone fragments occurred during operation in 4 cases; and knee effusion occurred in 2 cases and anterior knee pain in 1 case after operation. All incisions healed by first intention. Imaging evaluations at 3 months after operation showed the fracture healing and no internal fixation failure. All patients demonstrated good knee function and had returned to normal activities at 12 months after operation. At last follow-up, the knee joint range of motion was (133.44±4.17)°, Lysholm score 93.6±3.1, IKDC score 93.4±2.5, and VAS score 1.0±0.6, with significant differences compared to preoperative scores ( P<0.05). Conclusion: Arthroscopic suspension fixation with Endobutton in the treatment of tibial insertion avulsion fractures of PCL is simple to operate, and the knee joint function recovers well.

The Outcomes of Mini-Plate Fixation for Unstable Wagstaffe Tubercle Fracture, an Indirect Syndesmosis Injury in Rotational Ankle Fracture.

Background: Wagstaffe fracture constitutes an indirect injury to the AITFL and can precipitate syndesmotic instability. The prevailing fixation methods often involve the use of mini-screws or K-wires, with absorbable suture repair reserved for cases with small or comminuted fragments exhibiting instability. In this study, we devised a mini-plate fixation method capable of securing the fracture fragment irrespective of its size or condition. Methods: A retrospective chart review was conducted on patients who underwent surgery for ankle fractures between May 2022 and October 2023. The surgical technique involved direct fixation of the Wagstaffe fracture using mini-plate fixation. Radiologic evaluation was performed using postoperative CT images, and clinical outcomes were assessed using the OMAS and VAS. Results: Fourteen patients with an average age of 62.5 years were included. Most fractures were associated with the supination-external rotation type. The average preoperative OMAS significantly improved from 5.95 to 83.57 postoperatively. The average VAS score decreased from 7.95 preoperatively to 0.19 postoperatively. Conclusions: The mini-plate technique for Wagstaffe fractures exhibited dependable fixation strength, effective fracture reduction, a minimal complication rate, and judicious surgical procedure duration.

Complete Pectoralis Major Tendon Rupture With Bony Avulsion in an Adolescent Male: A Case Report and Literature Review.

Pectoralis major (PM) tendon ruptures are rare. Typically, they are caused by eccentric contractions from weight lifting. Due to the rarity of pectoralis major tendon ruptures, clinicians might misdiagnose this condition. We report a 16-year-old male with a right pectoralis major tendon rupture and an avulsion fracture after falling on a grass field playing soccer. He was initially misdiagnosed with biceps tendonitis, which highlights the importance of including pectoralis major tendon ruptures in one's differential diagnoses.

Ischial Tuberosity Avulsion Fracture Mimicking Calcified Mass on Plain Films: A Case Report.

Ischial tuberosity avulsion fractures are overall uncommon but are known injuries in the adolescent population. They are the result of sudden, forceful contraction of the hamstring muscle groups. The characteristic radiographic appearance of an ischial tuberosity avulsion fracture is of an irregular ischial margin and a nearby avulsed bone fragment. Callous formation may ensue and appears as a calcific density in the region of injury. Awareness of the spectrum of radiographic presentations can help ensure correct diagnosis and minimize concern for alternative underlying diagnoses. This case report describes a 14-year-old boy with a chronic ischial tuberosity avulsion fracture which demonstrated an unusual presentation on radiographs and required MRI to confirm the diagnosis and rule out other potentially ominous pathology.

Tibial Tubercle Avulsion Fractures in Adolescence in Sports Injury about Four Cases Series.

Introduction: Tibial tubercle avulsion fractures are a rare lesion in adolescence that occurs during sports such as basketball, soccer, and volleyball. They result from a forceful extension of the knee against a fixed leg. Case Report: Case 1: A 14-year-old adolescent who reportedly experienced severe knee pain when he jumped to head a ball during a soccer game. Case 2: A 17-year-old teenager who reportedly experienced severe knee pain on takeoff during a high jump event. Case 3: A 16-year-old who reportedly felt pain during takeoff to catch a basketball. Case 4: A 14-year-old adolescent who reportedly felt pain in his left knee on takeoff from a high jump during a basketball game. All of these patients presented with a defective leg extension on clinical examination. Radiographs showed an avulsion fracture of the anterior tibial tuberosity and treatment was surgical. Discussion: Avulsion fractures of the tibial tuberosity are rare lesions. They occur in adolescents during sports and are usually accompanied by fracture fragment displacement, indicating reduction, and internal fixation surgery by screwing. In the short term, the result is satisfactory. Conclusion: Tibial tuberosity avulsion fractures when managed in their entirety, give better results with a precocious return to sport.

Avulsion Fracture of the Tibialis Anterior Tendon Associated with First Metatarsal Base Fracture: A Case Report and Literature Review.

We present a unique case of a 59-year-old shipyard worker who sustained an avulsion fracture of the tibialis anterior tendon, concurrently with a comminuted fracture at the base of the first metatarsal. This is the first reported case highlighting this concomitant presentation, which underlines the possibility of avulsion fractures accompanying comminuted fractures. Importantly, such avulsion fractures could lead to skin tenting and potential necrosis, necessitating early identification and prompt intervention. The patient underwent successful surgical intervention and displayed good functional restoration 15 months postoperatively.

Management of Pediatric Volar Plate Avulsion Fractures of the Proximal Interphalangeal Joint: A Systematic Review.

BACKGROUND: Sudden, forced hyperextension injuries to the proximal interphalangeal joint leading to volar plate avulsion fractures are common hand injuries in children. Suboptimal management of these fractures can lead to the development of long-term complications such as stiffness and flexion contracture. METHODS: MEDLINE (PubMed), Scopus, Embase, Google Scholar, and Cochrane CENTRAL databases were systematically searched, and additional studies were found through reference of articles up to June 15, 2023. Identified articles were assessed using predetermined inclusion/exclusion criteria. RESULTS: Twenty-five articles were included, involving 268 patients with ages from 3 to 17 years. Fractures with less than 30% joint involvement, classified as Eaton type I or II, or designated as "Stable" in the Keifhaber-Stern classification, were treated through nonsurgical means. Surgical interventions, encompassing open reduction and internal fixation, were reserved for fractures with more than 30% joint involvement and/or meeting criteria such as Eaton type IIIa or IIIb and Keifhaber-Stern "Tenuous" or "Unstable." Positive outcomes were seen in 99.5% of patients receiving nonsurgical treatment, compared with 85.7% in the surgical cohort. CONCLUSIONS: The literature demonstrated positive outcomes for fractures presenting with less than 30% joint involvement that were managed nonsurgically. In fractures with more than 30% joint involvement, surgical interventions yielded positive results. To further substantiate these findings, larger prospective studies with uniform measures are needed to validate the results of this study.

Avulsion fracture of the anterior superior iliac crest following autograft for anterior lumbar fusion: case report and literature review.

Avulsion fracture of the anterior superior iliac crest (ASIC) following autogenous bone grafting for anterior lumbar fusion (ALF) is an extremely rare complication. We describe a very rare case of avulsion fracture of the ASIC following autograft for ALF in a revision surgery for treating lumbar tuberculosis. A 68-year-old woman with lumbar tuberculosis underwent posterior debridement and posterior iliac crest bone graft fusion; however, her lumbar tuberculosis recurred 9 months after surgery. She then underwent a lumbar revision surgery, including removal of the posterior instrumentation and debridement, followed by anterior L2 corpectomy, debridement, anterior left iliac crest bone graft fusion, and internal fixation. When walking for the first time on postoperative day 3, she experienced a sharp, sudden-onset pain in the anterior iliac crest harvest area. X-ray revealed an avulsion fracture of the ASIC. Considering her failure to respond to conservative treatment for one week and large displacement of the fracture ends, an open reduction and internal fixation surgery was scheduled. Her pain symptoms were significantly relieved after the operation. Although rare, fracture of the ASIC following autograft for ALF should not be ignored. Fracture of the ASIC is usually treated conservatively. Additional surgical treatment is required only when intractable pain fails to respond to conservative treatment or when there is a large displacement of fracture ends that are not expected to heal spontaneously.
