#1
Haroon Majeed, Donald J McBride
Fractures of the lateral and the posterior processes of the talus are uncommon and frequently missed because of a low level of suspicion and difficulty in interpretation on plain radiographs. Missed fractures can lead to persistent pain and reduced function.Lateral process fractures are usually a consequence of forced dorsiflexion and inversion of fixed pronated foot. These are also commonly known as snowboarder's fractures.The posterior process of the talus is composed of medial and lateral tubercles, separated by the groove for the flexor hallucis longus tendon...

Jae-Man Kwak, Gu-Hee Jung
BACKGROUND: Volar locking plating through the flexor carpi radialis is a well-established technique for treating unstable distal radial fractures, with few reported complications. In certain circumstances, including metaphyseal comminuted fractures, bridge plating through a pronator quadratus (PQ)-sparing approach may be required to preserve the soft tissue envelope. This study describes our prospective experience with bridge plating through indirect reduction. METHODS: Thirty-three wrists (four 23A2, six 23A3, 15 23C1, and eight 23C2) underwent bridge plating through a PQ-sparing approach with indirect reduction from June 2006 to December 2010...

REVIEW
Ezequiel Ernesto Zaidenberg, Ezequiel Martinez, Carlos Rodolfo Zaidenberg
Various methods have been reported to treat forearm nonunions with good results. However, in the presence of infection, inadequate vascularity of surrounding tissues, or failed prior grafts, vascularized bone grafts are a valid alternative. We describe the surgical technique to obtain distal radius vascularized bone graft pedicled on the radial artery (RA) and its clinical application in 1 case of an ulnar nonunion. We studied the surgical technique in 12 freshly injected cadavers. In the distal forearm, the RA provides several periosteal branches to supply the distal radius metaphysis...

PURPOSE: The posterior interosseous nerve (PIN) is at risk during the posterior and lateral approaches to the proximal radius. We aimed to define a safe zone for these approaches to avoid injury of the PIN and to evaluate their close and changing relationship to the nerve during forearm rotation. METHODS: The study collective consisted of 50 upper limbs. After performance of the lateral approach, the distance between the tip of the radial head and the PIN's exit point from the supinator (= distance 1) and the shortest interval between the nerve's exit to the radial margin of the ulna (= distance 2) were measured in maximum pronation and supination...

BACKGROUND: Complications related to extensor tendons have begun to increase with the use of volar plates in the treatment of distal radius fractures. In this study, we aimed to compare four-plane radiography and ultrasonography in the evaluation of dorsal cortex screw penetration following volar plate fixation. METHODS: We recruited 47 patients (33 males, 14 females, mean age 37.4 years; range 18-58 years). To evaluate dorsal screw penetration in all patients, we performed radiographs at 45° pronation, 45° supination and obtained dorsal tangential graphs at maximum palmar flexion, and a wrist lateral radiograph...

PURPOSE: Arthroscopic reduction and internal fixation for coronoid process fractures has been proposed to overcome limitations of open approaches. Currently, arthroscopy is most frequently used to assist insertion of a retrograde guide wire for a retrograde cannulated screw. The present anatomical study presents an innovative arthroscopic technique to introduce an antegrade guide wire from an accessory anteromedial portal and evaluates its safety and reproducibility. METHODS: Six fresh-frozen cadaver specimens were obtained and prepared to mimic an arthroscopic setting...

BACKGROUND: The paediatric flatfoot is a common presentation but it is unclear whether the condition will resolve on its own as the child gets older or whether treatment is required. Therefore, the study objective was to evaluate paediatric foot posture, and anthropometry, in children at two time points, three years apart. MATERIAL AND METHODS: A sample of 1032 healthy children (505 boys, 527 girls; aged 5-11 years) was recruited for foot posture index (FPI) and anthropometry assessment (weight, height and body mass index, BMI)...

BACKGROUND: Anatomic reduction and fixation of the syndesmosis in traumatic injuries is paramount in restoring function of the tibiotalar joint. While overcompression is a potential error, recent work has called into question whether ankle position during fixation really matters in this regard. Our study aimed to corroborate more recent findings using a fracture model that, to our knowledge, has not been previously tested. METHODS: Twenty cadaver leg specimens were obtained and prepared...

[Purpose] To clarify the motion-plane dependency of the range of dart throw motion and the effects of tendon action due to long finger flexors and extensors during the motion. [Subjects and Methods] Forty healthy subjects attended the experiment, and the active range of wrist motion in seven motion planes was measured with an originally designed apparatus. [Results] The reliability of the measurement was acceptable. The range of dart throw motion depended on the motion planes, with a maximum at around the motion plane of 45° from the sagittal plane (45° of pronation)...

BACKGROUND: We asked whether either open reduction and internal fixation (ORIF) or radial head arthroplasty (RHA), common techniques used for the confrontation of displaced or comminuted radial head fractures, are correlated with cartilage wear of the capitulum. HYPOTHESIS: We hypothesized that neither ORIF nor RHA are correlated with capitellar cartilage wear. MATERIAL AND METHODS: On 5 cadaveric elbow specimens, osteotomies were employed to simulate radial head comminuted fractures followed with ORIF by Herbert screws...
