BACKGROUND: Stahl ear, a rare congenital auricular anomaly, occurs when a third crus crosses the scaphoid fossa. Optimal elimination of the third crus and reconstruction the superior crus in type 1 Stahl ear remain undercharacterized. We present a novel 3-step technique to reliably correct a type 1 Stahl ear as a case report. METHODS: A 10-year-old male with bilateral prominent type 1 Stahl ears is presented. An anterior curvilinear helical fold incision and posterior V wedge excision was used for exposure...

INTRODUCTION: Fractures of the scaphoid account for the most commonly injured carpal bone. Minimally displaced fractures of the waist will heal in 85-90% when using a below elbow cast. However, fractures with displacement have a higher risk for nonunion. Therefore, open reduction and fixation with headless compression screws (HCS) have become the preferred method of treatment. The aim of this study was to compare the radiological and clinical outcome of unstable scaphoid B2 type fractures, stabilized using one or two headless compression screws...

PURPOSE: Through an anatomical review, the primary aim of this study was to delineate the dorsal thumb metacarpal (TM) periosteal branches of the radial artery (RA). In addition, we report here the clinical utility of a vascularized TM periosteal pedicled flap (VTMPF), supplied by the first dorsal metacarpal artery (FDMA), in a complex case of scaphoid nonunion. METHODS: Ten latex-colored upper limbs from fresh human cadavers were used. Branches of the RA were dissected under 3x loupe magnification, noting the periosteal branches arising from the FDMA...

We present the surgical outcomes of non-vascularized bone grafting taken from the iliac crest in 24 patients with scaphoid nonunion and avascular necrosis. The Fisk-Fernandez technique was used in 11 patients, and cancellous bone grafting was used in 13 patients. Bony union was achieved in 22 of the 24 patients. Non-vascularized iliac bone grafting can be used for the surgical management of scaphoid nonunion with avascular necrosis. Although revascularization of the proximal fragment after surgery was not evaluated, bony union was confirmed in nearly all patients...

INTRODUCTION: Radioscapholunate (RSL) fusion is typically performed following wrist trauma. It addresses the pain caused by radiocarpal osteoarthritis but reduces the wrist's mobility. The objective of this study was to determine the long-term clinical and radiological outcomes of this procedure. MATERIALS AND METHODS: This was a retrospective study of all wrists operated for RSL fusion in our surgery unit over a 12-year period. The clinical analysis consisted of joint amplitudes, grip strength, pain (VAS) and functional scores (PRWE, QuickDash, Mayo Wrist Score)...

The purpose of this study was to determine if screw placement in the reduction and association of the scaphoid and the lunate (RASL) procedure affected the ability of the scapholunate joint to withstand force. After completely disrupting of the scapholunate ligament in 29 fresh-frozen cadaveric wrists, we placed the RASL screw either distal or proximal to the lateral aspect of the dorsal ridge of the scaphoid and into the dorsal or volar aspect of the lunate. Specimens were subjected to repeated cycles of transcarpal axial force, mimicking clenched-fist loading, until failure...

Trans-scaphoid transcapitate (TSTC) perilunate fracture-dislocation (PLFD) is a rare type of perilunate injury. Because of the rarity and complexity of this entity, initial diagnosis may be delayed and the extent of osseous and ligamentous lesions underestimated. Early surgical treatment by open reduction and fracture stabilization is recommended to avoid complications such as avascular necrosis, nonunion, posttraumatic arthritis, and functional impairment. In this article, we report the case of a 32-year-old man who sustained a TSTC-PLFD...

The diagnosis of a scaphoid fracture, especially in the differentiation of a fresh fracture, the nonunion or a possible anatomical norm variant, can be difficult. We report on two patients who presented with stress-related, radiocarpal pain in our department. In both cases, radiological abnormalities were observed in the scaphoideal area, with a scaphoideum bipartitum on both sides, as well as an approximately 25-year-old scaphoid pseudarthrosis.

BACKGROUND: The incidence of wrong-bone excision in hand surgery is not known. The wrist offers a unique challenge in that a single surgical incision yields access to multiple potential surgical sites, thus rendering site marking less effective. Mistaken identification of structures in the wrist is a real and potentially troublesome phenomenon. This study is designed to evaluate the occurrence of wrong-bone excision and to identify any risk factors and preventative measures that may help to prevent this complication in the future...

BACKGROUND: Carpometacarpal joints can be affected by traumatic or degenerative pathology. Although different techniques have been described to treat these conditions, most authors agree that arthrodesis is an effective treatment modality. Vascularized bone grafts of the distal radius have been used to treat carpal conditions, such as scaphoid nonunion or Kiënbock disease, and they have been shown to have several advantages over nonvascularized bone grafts. METHODS: We report a case of a carpal boss in a female patient treated with an arthrodesis of the second and third carpometacarpal joints by using the fourth extensor compartment artery vascularized bone graft...

BACKGROUND: Articular cartilage injuries are a common injury among young, active patients, and the most appropriate treatment for these injuries remains controversial. A promising new technology in the treatment of high-grade cartilage injuries is particulated juvenile articular cartilage (PJAC) allograft (DeNovo NT, Zimmer, Warsaw, Indiana). This has been shown to be successful in multiple joints including the knee, talus, and elbow. No studies or case reports exist in supporting or discouraging its use in injuries of the wrist, in specific, the scaphoid...

BACKGROUND: Radiological grading of wrist osteoarthritis associated with scaphoid nonunion advanced collapse (SNAC) can be difficult. A comparison radiograph of the contralateral healthy wrist and an educational training in the various SNAC stages may improve reliability. Our purposes were to evaluate the difference in the reliability: (1) between observers who rate SNAC wrists with and without a comparison radiograph; and (2) between observers who receive training prior to ratings and those who do not...

The aim of the present study was to investigate the incidence of scaphoid fracture surgery by obtaining data from the national discharge register in Finland, a country of 5 million inhabitants, for the period from 1997 to 2014. A total of 1380 patients with scaphoid fracture were treated surgically. Half of the patients were aged under 28 years and 84% were men. The surgical treatment of scaphoid fractures was classified into two groups. There were 640 (46%) primary fracture fixations and 740 (54%) treatments of fracture nonunion...

The purpose of this study was to assess the long-term outcomes of radioscapholunate fusion, with and without distal pole of scaphoid excision and excision of the triquetrum. These compromised three operative groups. Seventeen patients were identified with a minimum of 10 years follow-up, with a mean of 15 years (range 10-19). Fifteen of the 17 patients were satisfied with their outcome. Two were converted to total wrist fusion. The mean outcomes scores were; pain visual analogue scale score 2.1/10, Quick Disabilities of the Arm, Shoulder, and Hand 29 and Modified Mayo Wrist score 60...

Scapholunate dissociation in stages 2 and 3 may lead to posttraumatic damage if left untreated. Different types of treatment have been described, including capsulodesis, tenodesis, and others. The purpose of all procedures is to avoid palmar shift of the distal scaphoid resulting in secondary arthritis (SLAC wrist). This study aimed to evaluate a modified dorsal ligamentoplasty in second- and third-degree scapholunate dissociation in a prospective study design. Furthermore, the study aimed to find out if there is a correlation between radiological and clinical parameters at follow-up and whether or not a SLAC wrist can be avoided...

REVIEW
Sanjeev Kakar, Ryan M Greene, Marc Garcia-Elias
Scapholunate instability can lead to posttraumatic dysfunction of the wrist. If unrecognized, it commonly leads to degenerative osteoarthritis. Numerous reparative techniques have been proposed with mixed long-term success. We present a technique that uses a distally based strip of the extensor carpi radialis longus to better maintain reduction of the scaphoid and reconstruct the volar and dorsal scapholunate ligament and the scaphotrapezium-trapezoid ligament. To illustrate the technique, we describe a clinical case with 17 months of follow-up...

BACKGROUND: Scaphoid non-union is often caused due to missed fractures, inadequate or inappropriate management. Matti-Russe and interpositional grafting techniques are used in the treatment of non-union. There are very few studies in literature that compare the outcomes of these techniques. The aim of our study was to analyse the factors influencing outcome in the management of scaphoid non-union and to compare the results of the Matti Russe procedure with interpositional grafting techniques...
