Chondromyxoid fibroma is a rare benign tumor of cartilaginous origin with myxoid and fibrous components. It accounts for approximately 1% of bone tumors. Metaphysis of long bones is the most common location of this tumor. However, there a few case reports of this tumor arising from epiphysis of short tubular bones of the hand and feet. An 11-year-old girl presented to our OPD with complaints of pain and a gradually progressive swelling of the right great toe. On examination, the swelling was diffuse with no signs of inflammation. X-ray examination revealed a well-defined, longitudinally oval lytic lesion in the right distal phalanx of great toe, involving the growth plate and, eroding the medial cortex. Computed tomography (CT) scan did not show any evidence of calcification, septations or involvement of soft tissue. Open biopsy and curettage was done and the specimen was sent for histopathological examination. Histopathological examination (HPE) showed a lobular pattern consisting of myxomatous stroma and immature cartilaginous cells in lacunae. The lobules were separated by fibrous septae. It was reported to be Chondromyxoid fibroma. The patient presented six months later with persisting pain and X-ray showed recurrence of the tumor. Hence, complete excision of the tumor was done and the defect was filled using synthetic bone graft. At six months follow up, the patient did not complain of pain and X-rays showed signs of bone formation with incorporation of the graft. Chondromyxoid fibroma is a low grade tumor, which may demonstrate nuclear atypia histologically and mimic chondrosarcoma. Differentiating these two is of paramount importance to avoid over-diagnosis and aggressive treatment. Recurrence is common with marginal excision and especially in younger patients like in our case. Complete resection is the mainstay of management. Long-term follow up of patients is necessary to watch for malignant transformation, a rare complication. Chondromyxoid fibroma is an extremely rare neoplasm of bone. There are no specific radiologic features, and histopathology provides a definitive diagnosis. It should be considered in differential diagnosis of lytic lesion, and differentiated from other tumors, especially from chondrosarcoma to treat the patient appropriately.

Suture-loaded long hollow needles are used in arthroscopic surgery to pass or retrieve sutures and in meniscal repair surgeries. However, manual suture loading can be time-consuming and challenging, especially with finer sutures. We present a novel technique using vacuum suction to simplify and expedite suture loading in hollow needles and similar devices.
Following ethical approval and participant consent, four healthcare professionals (one senior consultant, two junior consultants, and one trained operating theatre technician) attempted to load 16G and 18G needles, as well as free and double-loaded commercial anchor drivers, using manual and vacuum suction techniques. The best of three attempts was recorded for each participant. Loading times were compared using permutation tests, and inter-operator variability was analyzed via F-tests.
Across all devices, the suction method reduced loading times significantly compared to manual loading, with times dropping to 2-4 seconds. The senior consultant required 15 seconds for manual loading, while the untrained junior consultant took up to 60 seconds. Permutation tests revealed statistically significant time reductions with suction loading (p = 0.0286 for all devices). F-tests showed a substantial decrease in variability with suction loading, confirming greater consistency across users.
Vacuum suction is a quick, economical, and effective technique for loading sutures into long hollow needles and other devices. It not only drastically reduces loading times but also improves consistency across different users, making it a reliable technique for arthroscopic procedures. This method can potentially be applied to various surgical instruments, improving procedural efficiency and outcomes.

Anterior Labrum Periosteal Sleeve Avulsion Lesions of the Shoulder: A Scoping Review
Background:
Anterior labrum periosteal sleeve avulsion (ALPSA) lesion of the shoulder is defined as a labral avulsion with an intact periosteum of the glenoid neck resulting in medial malattachment of the labrum, which is both nonanatomic and nonfunctional. It is relatively rare compared with Bankart lesions, and its results are usually reported in combination with other anterior labroligamentous lesions in the literature.
Purpose:
To (1) assess the size and scope of the literature on ALPSA lesions, (2) highlight the importance of this lesion, and (3) distinguish between ALPSA and Bankart lesions in diagnostic and treatment strategies.
Study Design:
Scoping review; Level of evidence, 4.
Methods:
The PubMed, Scopus, Embase, and Google Scholar databases were searched with the keywords “ALPSA,”“anterior labrum periosteal sleeve avulsion,”“anterior labral periosteal sleeve avulsion,” and “anterior labroligamentous periosteal sleeve avulsion” lesion. Duplicate articles and those that did not meet the inclusion criteria were excluded, resulting in the identification of 42 relevant articles. Their references were analyzed for further data curation.
Results:
This scoping review demonstrated that ALPSA lesions are difficult to clinically identify. Magnetic resonance angiography in the adduction internal rotation position is the most sensitive and specific imaging modality for identification. Optimal views are the anterosuperior portal for accurate identification and the anteroinferior portal for surgical repair during arthroscopy. Treatment begins with correctly identifying the labrum, in contradistinction to dense reactive fibrous tissue, and reattaching the labrum to the correct anatomic glenoid footprint. Chronic lesions with bone loss require either bone block or soft tissue augmentation procedures.
Conclusion:
There is paucity of exclusive literature on ALPSA lesions. It is important to distinguish this lesion from the Bankart lesion as it is associated with worse outcomes. The higher failure rates of ALPSA lesion repair indicate that the current repair techniques require further refinement to improve the outcomes to the standard of Bankart lesions.
