Overview

• The ulnar nerve is the most frequently involved nerve in revision total elbow arthroplasty [1].
• Radial nerve injury accounts for a substantial proportion of nerve injuries in revision total elbow arthroplasty [1].
• Anatomical anterior and posterior reconstruction for scapholunate dissociation resulted in no patients requiring secondary surgery or treatment related to carpal stabilization [2].
• A negative MRI result is unable to rule out clinically relevant injury to the triangular fibrocartilage complex (TFCC) of the wrist [4].
• A negative MRI result is unable to rule out clinically relevant injury to the scapholunate (SL) ligament of the wrist [4].
• A negative MRI result is unable to rule out clinically relevant injury to the lunotriquetral (LT) ligament of the wrist [4].
• Arthroscopic dorsal capsuloligamentous repair for chronic scapholunate ligament tears showed encouraging preliminary results in a series of 36 patients [5].

• Radioscapholunate arthrodesis with compression screws and local autograft had no complications in the reported series [7].
• There is a lack of consensus in carpal tunnel management for patients with perilunate dislocations [9].
• The lack of consensus in carpal tunnel management for perilunate dislocations is due to few studies with small sample sizes and inconsistent follow-up [9].
• Both wrist arthrodesis and revision total wrist arthroplasty (TWA) are technically demanding procedures [10].
• Revision wrist arthroplasty strategies should be performed with multidisciplinary team input, preferably in a specialist centre [10].

Anatomy & Pathophysiology

• A negative MRI result cannot rule out clinically relevant injuries to the triangular fibrocartilage complex (TFCC), scapholunate (SL) ligament, or lunotriquetral (LT) ligament [4].
• Four-dimensional computed tomography (4DCT) is a non-invasive and affordable method to assess and quantify wrist kinematics by incorporating the temporal dimension [3].
• An individualized, multimodal approach combining clinical examination, imaging, and direct arthroscopic evaluation is essential for early diagnosis of scapholunate injuries and prevention of arthritis progression [12].
• Sensorimotor techniques including proprioceptive retraining may improve pain, neuromuscular control, and functional outcomes in patients with chronic wrist pain due to ligament injury without structural instability [14].
• A consistent longitudinal branch of the posterior antebrachial cutaneous nerve (PABCN) courses over the interval between the brachioradialis and the extensor carpi radialis longus in the proximal third of the forearm [15].

Classification

• Four-dimensional computed tomography (4DCT) is a method to assess and quantify wrist kinematics by incorporating the temporal dimension [3].
• A negative MRI result cannot rule out clinically relevant injury to the triangular fibrocartilage complex (TFCC), scapholunate (SL) ligament, or lunotriquetral (LT) ligament [4].
• Dorsal extrinsic ligaments demonstrate MRI signal changes suggestive of acute or chronic injury in patients with an SL interval of 2 mm or greater more often than in patients with an SL interval less than 2 mm [8].
• An individualized, multimodal approach combining clinical examination, imaging, and direct arthroscopic evaluation is essential for early diagnosis of SL injuries [12].
• Lunate fracture-subluxations are unstable injuries best managed with fixation of the carpal fractures [18].
• Lunate fracture-dislocations are complex injuries requiring stabilization of the lunate, associated fractures, and ligament injuries [18].

Clinical Presentation

• Ulnar nerve injury is the most frequently involved nerve injury in revision total elbow arthroplasty [1].
• There is a lack of consensus on carpal tunnel management in patients with perilunate dislocations due to few studies with small sample sizes and inconsistent follow-up [9].
• Sensorimotor techniques including proprioceptive retraining may improve pain, neuromuscular control, and functional outcomes in patients with chronic wrist pain due to ligament injury [14].
• Patients with dorsal radiotriquetral ligament snapping wrist syndrome demonstrated complete resolution of symptoms after debridement of thickened scar tissue on the undersurface of the dorsal radiotriquetral ligament [16].
• Lunate fracture-dislocations are complex injuries requiring stabilization of the lunate, associated fractures, and ligament injuries, and are associated with common complications [18].
• Symptomatic improvement can occur following carpal tunnel release in patients with severe carpal tunnel syndrome [26].

Investigations

• Four-dimensional computed tomography (4DCT) is a promising, non-invasive, and affordable method to assess and quantify wrist kinematics, extending conventional CT by incorporating the temporal dimension [3].
• A negative result from MRI is unable to rule out the possibility of a clinically relevant injury to the TFCC, SL ligament, or LT ligament of the wrist [4].
• Dorsal extrinsic ligaments demonstrate MRI signal change suggestive of acute or chronic injury in patients with an SL interval 2 mm or greater more often than in patients with an SL interval less than 2 mm [8].
• The sensitivity and specificity of MRI are influenced by the anatomic location of the lesion and technical conditions [35].
• There is no evidence for the superiority of 3 Tesla Magnetic Resonance Imaging over 1.5 Tesla Magnetic Resonance Imaging for diagnosing wrist ligamentous lesions [35].
• An individualized, multimodal approach that combines clinical examination, imaging, and, when appropriate, direct arthroscopic evaluation is essential for early diagnosis of SL injuries and prevention of arthritis progression [12].

Treatment

• Arthroscopic dorsal capsuloligamentous repair in chronic scapholunate ligament tears showed encouraging preliminary results including pain relief, recovery of grip strength, low incidence of postoperative wrist stiffness, and all professional athletes returning to preinjury sports levels [5].
• Radioscapholunate arthrodesis with compression screws and local autograft is an effective method for appropriately selected patients with a preserved midcarpal joint, achieving a 100% union rate at mean follow-up of 12 months with no complications [7].
• Surgical intervention for palmar midcarpal instability using autograft reconstruction of the radiotriquetral ligament and controlled thermal capsulorrhaphy showed lasting symptom relief and improved patient-reported outcomes in 7 patients at an average of 34 months after surgery [13].
• Staged reduction of neglected transscaphoid perilunate fracture dislocation results in good functional pain-free range of motion if properly executed [17].
• Lunate fracture-dislocations are complex injuries requiring stabilization of the lunate, associated fractures, and ligament injuries, with common complications [18].
• Proximal migration of the thumb metacarpal does not appear to influence functional outcome in ligament reconstruction with or without tendon interposition to treat primary thumb carpometacarpal osteoarthritis [6].
• Four-corner fusion versus proximal row carpectomy for scapholunate advanced collapse and scaphoid nonunion advanced collapse wrists shows that proximal row carpectomy results in better outcomes and a lower complication rate compared to four-corner fusion [28].

Complications

• Nerve injury is a complication of revision total elbow arthroplasty, with the ulnar nerve being the most frequently involved and the radial nerve accounting for a substantial proportion of cases [1].
• No patient required secondary surgery or treatment related to carpal stabilization in a series of ten patients undergoing anatomical anterior and posterior reconstruction for scapholunate dissociation [2].
• Arthroscopic dorsal capsuloligamentous repair for chronic scapholunate ligament tears is associated with a low incidence of postoperative wrist stiffness [5].
• Radioscapholunate arthrodesis with compression screws and local autograft achieved a 100% union rate with no complications in appropriately selected patients with a preserved midcarpal joint [7].
• Closed surgical techniques for acute perilunate injuries may result in a smaller postoperative scapholunate gap and better wrist flexion–extension angle and MMW scores compared to open surgery, although the causal relationship is uncertain due to potential differences in injury severity between cohorts [11].
• Surgical intervention for palmar midcarpal instability using autograft reconstruction of the radiotriquetral ligament and controlled thermal capsulorrhaphy showed lasting symptom relief and improved patient-reported outcomes in a series of 7 patients at an average of 34 months after surgery [13].
• Quadriceps tendon autograft with or without bone block have comparable complications for ACL reconstruction [19].
• Ulnar collateral ligament reconstruction (UCLR) demonstrates low complication and revision rates at minimum 48-month mean follow-up [21].
• There is an association between longer follow-up and higher revision rate in rotator cuff repair study designs [24].
• Shoulder arthroplasties are generally designed to last 10-15 years, but revisions are being performed at a mean of 3.9 years from the primary procedure [34].
