BACKGROUND: Our goal was to analyze the movement of acute scaphoid waist fracture fragments and adjacent bones in a common coordinate system. Our hypothesis was that the distal scaphoid fragment flexes and pronates and the proximal fragment extends. METHODS: Computed tomography (CT) scans of patients diagnosed with an acute scaphoid waist fracture were evaluated using a 3-dimensional (3D) model. The scans of 57 nondisplaced and 23 displaced fractures were compared with a control group of 27 scans showing no pathological involvement of the wrist...

PURPOSE: To compare the patient-reported, clinical, and radiographic outcome of 2 methods of internal fixation in distal radius fractures. METHODS: Fifty patients, mean age 56 years (range, 21-69 years) with primarily nonreducible or secondarily redisplaced distal radius fractures were randomized to open reduction internal fixation using volar locking plates (n = 25) or fragment-specific fixation (n = 25). The patients were assessed on grip strength, range of motion, patient-reported outcome (Quick Disabilities of the Arm, Shoulder, and Hand), pain (visual analog scale), health-related quality of life (Short Form-12 [SF-12]), and radiographic evaluation...

BACKGROUND: Manipulating the carpal arch width (i.e. distance between hamate and trapezium bones) has been suggested as a means to increase carpal tunnel cross-sectional area and alleviate median nerve compression. The purpose of this study was to develop a finite element model of the carpal tunnel and to determine an optimal force direction to maximize area. METHODS: A planar geometric model of carpal bones at hamate level was reconstructed from MRI with inter-carpal joint spaces filled with a linear elastic surrogate tissue...

RATIONALE: For localized type Volkmann's contracture, in which degeneration of the flexor digitorum profundus (FDP) muscle to one or two fingers and restriction of finger extension occur, dissection or excision of the affected muscle is usually recommended. However, these surgical procedures need relatively wide exposure of the muscle, because the FDP muscle is in the deep portion of the forearm. PATIENT CONCERNS: In this report, the case of a 35-year-old woman with localized type Volkmann's contracture is presented...

Upper extremity fractures in the elderly are very frequent and second only to hip fractures in the group of fragility fractures. Their impact on mobility and functional decline seems to be underestimated especially when they occur in combination with lower extremity fractures. Fractures of the proximal humerus and the distal radius can often be treated conservatively; however, the indications for operative treatment must not be based on fracture morphology alone and due consideration should be given to all concomitant circumstances affecting functional aspects of patients...

Hand and wrist infections can present with a spectrum of manifestations ranging from cellulitis to deep-space collections. The various infectious processes can be categorised as superficial or deep infections based on their respective locations relative to the tendons. Superficial hand infections are located superficial to the tendons and are comprised of cellulitis, lymphangitis, paronychia, pulp-space infections, herpetic whitlow, and include volar as well as dorsal subcutaneous abscesses. Deep hand infections are located deep to the tendon sheaths and include synovial space infections, such as infectious tenosynovitis, deep fascial space infections, septic arthritis, necrotising fasciitis, and osteomyelitis...

PURPOSE: To report outcomes of patients with distal radius fracture malunions treated with corrective osteotomy and orthogonal volar and radial "90-90" plate fixation. METHODS: We performed a retrospective review of all patients who underwent distal radius corrective osteotomy and 90-90 fixation from January 2008 through December 2014. Demographic data, injury history, prior treatments, and clinical examination values were recorded. Preoperative radiographic measurements were used to classify the type and severity of deformity...

INTRODUCTION: Distal radius fracture are common injuries but no gold standard for their therapy exists. The aim of this study was to evaluate the quality of fracture care in distal radius fractures using an intramedullary implant (Targon DR interlocking nail). The nail had been developed to minimize the surgical exposure, increase fixation strength, to prevent tendon irritations and to allow for a fast return to activity. PATIENTS AND METHODS: Prospective study reports the result of 43 patients with an age over 70 years (range 70-91 years) treated by closed reduction and intramedullary fixation...

BACKGROUND: Proposed benefits of intramedullary techniques include limited soft tissue dissection while affording sufficient stability to allow early wrist motion. The primary null hypothesis of this randomized trial was that there is no significant difference with respect to functional outcome, pain and disability between patients treated with either 2.4-mm volar locking plate fixation or intramedullary nail fixation of intra-articular fractures of the distal radius. METHODS: We conducted a single-centre, prospective randomized matched-pairs trial...

This case presents surgical treatment of a unique form of syndactyly: an isolated fenestrated, complex, crisscross syndactyly of the right middle and ring fingers. A 2-year-old boy presented with the ring finger lying dorsal and the middle finger lying volar, with the middle phalanges syndactylized. A surgical release was performed with a subsequent z-plasty, 2 years later, for scar elongation. At the age of 4, he has essentially full function of his hand with minimal limitations. This case demonstrates that 2 digits that were syndactylized in a coronal plane (ring finger dorsal and middle finger volar) can be successfully surgically separated...

A 79-year-old man presented with a painless, soft, subcutaneous mass lesion of the right volar wrist that had been slowly growing for 3 years. A cloudy, yellow serous effusion was aspirated from the punctured mass, from which Phaeoacremonium spp., an extremely rare cause of tenosynovitis, was isolated in culture. Total synovectomy was performed without the use of antifungal agents. No recurrence or complications occurred as of 6 months after surgery. Fungal infection is rare but should be considered in the differentiation of chronic tenosynovitis...

INTRODUCTION: Perilunate dislocations are commonly seen after fall on an outstretched hand in extremes of dorsiflexion and ulnar deviation. A greater arc injury is one when there is an associated fracture of one or more bones around the lunate while a lesser arc injury is associated with pure ligamentous disruption around the lunate. CASE REPORT: We report a unique case of bilateral trans-scaphoid perilunate dislocation in a 35-year-old male labourer. This is the first reported case where the lunate dislocated into the forearm on the volar aspect...

Dislocation of the lunate and proximal pole of the scaphoid with displacement of the fragments proximal to the radiocarpal joint, characterized as a total dislocation, is very rare, with only six cases reported. Dislocated lunate are generally located around the radiocarpal joint or within carpal ligament. However, there have been no reports of dislocated lunate over the carpal ligament. We present a patient with volar dislocation of the lunate that featured extreme migration to approximately 6 cm proximal to flexor digitorum superficialis through the transcarpal ligament...

Mark Henry
The more common dorsal fracture subluxations at the base of the middle phalanx have an intact dorsal buttress of articular surface in continuity with the shaft. Capitalizing on this foundation, various fixation methods have met with relatively equivalent success including Kirschner wires, screws only, nonlocking plate and screws, and external fixation. Pilon fractures are complete articular fractures, where the comminuted articular fragments lack any structural connection to the more distal shaft of the middle phalanx, and have largely relied upon external fixation traction systems...

We report a 38-year-old male with a nonunion followed by plate breakage after volar plating of a distal radius osteotomy. Volar locking plates have added a new approach to the treatment of distal radius malunions, due to a lower morbidity of the surgical approach and the strength of the final construction, allowing early mobilization and return to function. Conclusion. Plate breakage is an uncommon complication of volar locking plate fixation. To our knowledge, few cases have been described after a distal radius fracture and no case has been described after a distal radius corrective osteotomy...

RATIONALE: Florid reactive periostitis is a rare, benign bone and chondrogenic lesion that develops most frequently in the phalanges of the hands. Although the definitive cause of florid reactive periostitis is unknown, the major inciting factor is generally considered to be trauma, including repetitive minor trauma. PATIENT CONCERNS: We present a case of florid reactive periostitis affecting two contiguous phalangeal bones of the left fifth phalange of a 23-year-old male professional boxer...

Our purpose was to compare postoperative complications and rate of plate removal in titanium and stainless-steel plating of distal radius fractures (DRF). Patients following DRF were randomly fixed with titanium or stainless-steel plates using the same plating system. Complications, second surgeries, and plate prominence were documented. A total of 41 patients were treated with stainless-steel and 22 with titanium plates. Average follow-up was 60 ± 5.6 months. There was no difference in demographics, fracture characteristics, or follow-up between the groups...

A case of volar forearm pain associated with ulnar nerve paresthesia caused by a reversed palmaris longus muscle is described. The patient, an otherwise healthy 46-year-old male laborer, presented after a previous unsuccessful forearm fasciotomy for complaints of exercise exacerbated pain affecting the volar forearm associated with paresthesia in the ulnar nerve distribution. A second decompressive fasciotomy was performed revealing an anomalous "reversed" palmaris longus, with the muscle belly located distally...

The aim of the present study was to assess the technical feasibility of minimally invasive volar plate removal following distal radius fracture. 388 plates removed from 387 patients (357 female: mean age, 50 years) were assessed retrospectively. The incision used the primary minimally invasive approach and was closed after plate removal by intradermal continuous suture, without drainage or immobilization. Mean scar size was 22.2mm preoperatively, and the incision was 19.8mm at start and 21.4mm at end of procedure, these differences being non-significant...
