Background: Avulsion fractures of the base of proximal phalanx associated with ulnar or radial collateral ligament instability are relatively rare. The small size of the fragment and strong deforming pull of the attached soft tissues make the process of reduction and maintenance difficult.Objective: The purpose of this study was to assess the functional outcome of tension band wiring in intra-articular avulsion fractures of the base of the proximal phalanx.Methodology: A prospective study was performed on ten patients with intra-articular collateral ligament avulsion fractures of the proximal phalanx (Jupiter’s classification Type III). A tension band construct was performed using a dorsal approach. The functional outcome was assessed at six months with the quick Disability of Arm, Shoulder and Hand score.Results: The mean age of the patients was 25.8 years (Mean ± SD: 25.80). Six avulsion fractures were of the ulnar collateral ligament of the proximal phalanx of the index finger, one involved the radial collateral ligament of the ring finger and three, the radial collateral ligament of the little finger suggesting an abduction injury. All fractures had united at three months. Eight patients were graded as excellent and two as good. All patients were satisfied with the surgery and the functional outcome of the injured digit. There were no perioperative complications.Conclusion: The functional outcome of tension band wiring in intra-articular collateral ligament avulsion fractures of the base of the proximal phalanx was good to excellent.

Irreducible volar subluxation should be considered when assessing a patient with flexion deformity of the proximal interphalangeal finger joint (PIPJ). Primary assessment requires careful examination of the collateral ligaments and extensor tendon. Preoperative imaging such as ultrasound and MRI can help identify the interposed structures and plan the subsequent operation. Although rare, irreducible volar subluxation due to radial collateral ligament interposition is an important entity to be aware of. Prompt and appropriate management can prevent joint stiffness and loss of function.

Practical relevance: Feline carpal injuries are usually caused by falls from a height that result in hyperextension injury or antebrachiocarpal luxation or subluxation. Isolated ligamentous damage or fracture of the carpus is unusual; it is more common to have a combination of both in the cat. These injuries can be debilitating since cats climb and jump from great heights, and have a greater range of antebrachial pronation and supination than dogs. Anatomy: There are differences in the anatomy of the feline and canine carpus. In particular, cats only have a single short radial collateral ligament, also known as the medial collateral ligament. This means that, in the cat, antebrachiocarpal subluxation is possible with rupture of the dorsal joint capsule and short radial collateral ligament alone. Clinical challenges: Many feline carpal injuries can be treated without performing pancarpal arthrodesis. However, determining which ligaments and joint levels are affected requires careful examination and often stress radiography. When pancarpal arthrodesis is performed in the cat, it has been reported to reduce the height of jumping and to increase reluctance to climb. This is speculated to be due to reduced pronation and supination movement of the carpus. Evidence base: The current evidence base for management of feline carpal injuries is grade III or IV, with most of the studies being retrospective case series involving cadaveric dissection or direct extrapolation from published information about the dog. There are few guidelines regarding the optimal treatment options for carpal injuries in the cat.
