This confirms all five answers. Here they are with rationale:

Q21. The fascia which is generally not involved in Dupuytren's contracture is: A. Cleland's ligament Cleland's ligaments (dorsal to the neurovascular bundle) are classically spared in Dupuytren's disease, while Grayson's (volar) ligaments, the spiral bands, and pretendinous cords are involved. - Miller's Review of Orthopaedics, 9th Ed.

Q22. Pitchers with valgus extension overload syndrome are most symptomatic due to: C. Osteophytes In overhead-throwing athletes, repetitive valgus stress causes posteromedial olecranon osteophytes that impinge in the olecranon fossa during terminal elbow extension, producing pain in the deceleration phase of throwing. - Miller's Review of Orthopaedics, 9th Ed.

Q23. Tendon most commonly ruptured in rheumatoid disease: C. Extensor pollicis longus Attrition rupture of the EPL tendon (as it crosses Lister's tubercle) is the classic tendon rupture seen in rheumatoid arthritis, typically in middle-aged women; it can also occur after Colles' fracture. - S. Das, A Manual on Clinical Surgery, 13th Ed; also noted as Vaughan-Jackson syndrome pattern in Miller's Review.

Q24. A positive Barlow's test in an infant indicates: A. Hip instability The Barlow test (adduction with posterior/downward pressure on the flexed hip) dislocates a dislocatable hip, used in newborn screening for developmental dysplasia of the hip (DDH). Ortolani's test is the complementary maneuver that relocates a dislocated hip. - Miller's Review of Orthopaedics, 9th Ed.

Q25. Primary benefit of CPM after ligament reconstruction (of the knee - hip is a likely OCR misread of "knee") is: C. Reduction of adhesion formation Continuous passive motion is used post-operatively to maintain range of motion and decrease the incidence of adhesion formation while cartilage and soft tissue heal; this is its principal rationale in rehabilitation protocols. - Rockwood and Green's Fractures in Adults, 10th Ed; consistent with Kisner's Therapeutic Exercise.

Quick recap of Q21-25 answers: A, C, C, A, C

A recent-evidence check via PubMed wasn't necessary here since these are well-established, textbook-level orthopedic facts unlikely to have been revised by recent meta-analyses/systematic reviews.
