Hamate-pisiform coalition is an exceptional form of carpal coalition. Case reports are essential to gain a better understanding of this variant. We report a case of congenital bilateral hamate-pisiform coalition in a 20-year-old male discovered in the context of a right wrist trauma. Radiographs also revealed a bilateral scapholunate diastasis. Clinical examination and radiological findings suggested that the right wrist scapholunate diastasis was related to scapholunate instability. Left wrist scapholunate diastasis could be related to (1) a pathological feature or (2) a normal variant associated with hamate-pisiform coalition...

Background Ulnar variance (UV), which is measured using anteroposterior (AP) X-rays, is associated with the development of multiple wrist pathologies. The scapholunate angle (SLA) and capitolunate angle (CLA) are measured using lateral X-rays, and these can be used in the diagnosis of intercalated segmental instability. Purpose To determine the effect of UV on SLA and CLA. Material and Methods A total of 140 patients (73 women, 67 men; mean age, 37.8 ± 14.6 years; 95% confidence interval [CI], 35.4-40...

Background: Fractures of the proximal pole of the scaphoid can be difficult to heal because of its limited vascular supply. Furthermore, nonunion with avascular necrosis and secondary fragmentation makes surgical reconstruction a challenging procedure. Method: We describe a technique and report the outcome of a proximal hamate autograft to treat a proximal pole scaphoid nonunion with avascular necrosis. Results: At 3.5 years post reconstruction, the patient remains asymptomatic with union of his scaphoid reconstruction without any evidence of scapholunate instability...

BACKGROUND: Scapholunate dissociation is the most common form of carpal instability. However, there is no gold standard for operative treatment. In this prospective observational study on 54 patients, a modified minimally invasive dynamic extensor carpi radialis longus tenodesis is described, which is characterized by a smaller approach and application of a cannulated screw and washer for tendon fixation. METHODS: Quick-Disabilities of Arm, Shoulder and Hand (DASH)-questionnaire results, post-operative satisfaction, range of motion and grip strength are analyzed...

Purpose A proximal avulsion of the radiocarpal capsule (PARC) is a cause of persisting posttraumatic wrist pain. This lesion is often overlooked and left untreated during wrist arthroscopy. Materials and Methods A record review was performed on 13 patients with this lesion who underwent diagnostic wrist arthroscopy after failed conservative treatment. We retrospectively reviewed the results of an arthroscopic repair method in 13 patients. Results In 11 of the 13 consecutive cases the lesion was sutured using an arthroscopic dorsal capsule-ligamentous repair technique...

PURPOSE OF THE REVIEW: Scapholunate and perilunate injuries can be difficult to diagnose and treat in the athlete. In this review article, we present the mechanism of injury, evaluation, management, and outcomes of treatment for these injuries. RECENT FINDINGS: Acute repair of dynamic scapholunate ligament injuries remains the gold standard, but judicious use of a wrist splint can be considered for the elite athlete who is in season. The treatment of static scapholunate ligament injury remains controversial...

Raviv Allon, Aviv Kramer, Ronit Wollstein
Surgical treatment of scaphoid nonunion is not always successful, often requiring stabilization and bone grafting to achieve healing. Even after intramedullary screw fixation, residual instability may still hinder union. The purpose of this study was to describe the addition of Kirschner wires (KWs) through the capitate and the lunate to supplement an intramedullary screw for temporary enhanced stability, possibly improving healing of unstable fractures. A case-control study reviewing 25 cases with addition of KWs and 19 controls was performed...

PURPOSE: Scaphoid fracture commonly occurs around the mid-third of the scaphoid, and non-union of this fracture has several treatment options. The authors performed autologous cancellous bone graft from the iliac crest and headless compression screw fixation for the treatment of Mack-Lichtman type II scaphoid waist non-union. The purpose of this study was to determine whether this procedure was effective in achieving bony union and restoration of alignment. METHODS: Medical records and radiographs of 30 patients who underwent cancellous bone graft and headless compression screw fixation for non-union of scaphoid waist fracture were retrospectively reviewed...

The authors present a case of isolated scaphoid dislocation in a 40-year-old male that was undiagnosed for 2 months. The patient was treated by open reduction, Kirschner wire fixation, interosseous ligament repair using a suture anchor and Blatt's dorsal capsulodesis. At 6 years followup, his radiographs of wrist showed a normal carpal alignment with a scapholunate gap of 3 mm and no evidence of avascular necrosis (AVN) of the scaphoid.

BACKGROUND: Multiple reconstruction techniques have been described in the management of chronic scapholunate (SL) instability, either based on the capsulodesis or tenodesis principle. It is uncertain which surgical method produces the best patient outcomes. We describe results of a technique using palmaris longus (PL) tendon for surgical reconstruction of the SL ligament and provide functional outcomes scores. MATERIALS AND METHODS: We surgically reconstructed the SL ligament using a PL tendon graft secured with Mitek(®) bone anchors...

Scapholunate (SL) ligament injuries generally result from trauma to an extended, supinated wrist, leading to chronic instability that progresses toward osteoarthritis. They can occur together with distal radius fracture. These injuries can be difficult to diagnose, especially early on. Treating chronic SL ligament injuries before the onset of osteoarthritis is still a challenge for surgeons. Until recently, the recommended treatments consisted of open SL ligament reconstruction or repair procedures that reduce pain and improve pinch strength but also lead to wrist stiffness...

REVIEW
Rick Tosti, Eon Shin
Management of hand and wrist injuries for athletes often places emphasis on an expeditious return to sport. Arthroscopic techniques have the advantage of directly visualizing joint derangements and correcting them via a minimally invasive approach. This article discusses the evaluation and management of common wrist injuries treated with arthroscopy in athletes, including scapholunate and lunotriquetral injury, triangular fibrocartilage complex tears, hamatolunate impingement, and arthroscopic-assisted reduction of wrist fractures...

Scapholunate advance collapse (SLAC) and Scaphoid nonunion advance collapse (SNAC), are the two most common patterns of postraumatic wrist arthritis. SLAC wrist develops after attenuation, either traumatically or atraumatically, of the scapholunate ligament. Atraumatic causes of SLAC wrist include calcium pyrophosphate dehydrate deposition disease, reumathoid arthritis, neuropathic diseases, and b2-microglobulin asociated amyloid deposition diseases. On the other hand, SNAC wrist develops following a scahpoid fracture that has progressed to a nonunion...

Ganglion cysts are the most common wrist tumors, and 60 -70% originate dorsally from the scapholunate interval. Ossification of these lesions is exceedingly rare, with only one such lesion located in the finger reported in the literature. We present a case of an ossified dorsal wrist ganglion in a 68-year-old woman.
