The distal radioulnar joint (DRUJ) is vital to the stability and function of the wrist and forearm. The osseous morphology is variable and provides little stability. A complex of confluent soft tissues is the primary stabilizer; however, the contribution of each component has yet to be elucidated.

Although proximal interphalangeal joint dislocations are generally straightforward to treat, fracture-dislocations are among the most difficult hand injuries to manage. Fracture patterns range from simple to treat palmar plate avulsion fractures to complex, unstable pilon fractures of the base of the middle phalanx, where achieving adequate reduction and fixation can be extremely difficult. Moreover, these fractures may present sub-acutely or chronically, which greatly adds to the complexity of the case.

Background: Revision of radial head arthroplasty (RHA) may be indicated in cases of prosthesis loosening and malposition. Inherent difficulties in revision surgery include poor bone stock and disrupted soft tissue envelope. Although cases of RHA used for revision of failed RHA are rare, there is reasonable expectation for increasing frequency of these cases due to the increasing incidence of primary RHA.

No consensus regarding optimal treatment or etiology of Preiser disease exists. We described the epidemiology, classification and treatment characteristics of 18 patients with Preiser disease. Patients with changes related to previous trauma, and without radiographs were excluded.

This study addresses the prevalence of discrete pathophysiology accounting for patients' symptoms during diagnostic wrist arthroscopy in individuals with wrist pain without a specific preoperative diagnosis. Secondarily, we determined the number and type of surgeries subsequent to diagnostic wrist arthroscopy. Between January 2000 and January 2015, 135 diagnostic wrist arthroscopies were performed by 12 surgeons in 3 urban academic hospitals.

Purpose: In this anatomical cadaver study, the distance between major nerves and ligaments at risk for injury and portal sites created by trainees was measured. Trainees, inexperienced in elbow arthroscopy, have received a didactic lecture and cadaver instruction prior to portal placement. The incidence of iatrogenic injury from novice portal placement was also determined.

Accurate assessment of partial-thickness flexor tendon lacerations in the hand is difficult owing to the subjectivity of evaluation. In this study, we created 12 partial-thickness flexor tendon lacerations in a cadaveric hand, evaluated the accuracy of 6 orthopedic residents and 4 fellowship-trained hand surgeons in estimating the percentage thickness of each laceration, and assessed the groups' interobserver and intraobserver agreement. The 10 participants estimated each laceration independently and on 2 separate occasions and indicated whether they would repair it.

Introduction: Humeral shaft nonunions can lead to morbidity from subsequent operations, complications and impaired function. Currently there is no evidenced-based consensus for treatment of humeral shaft nonunions.

Aim: We aimed to summarize and analyze union rates and complications after operative treatment for humeral shaft nonunion.

Purpose: To identify factors associated with reoperation for early loosening or breakage of implants or nonunion after operative treatment of AO type C distal humerus fractures.

Methods: We retrospectively analyzed 129 adult patients who had operative treatment of an isolated AO type C distal humerus fracture at 1 of 5 hospitals to determine factors associated with reoperation for early loosening or breakage of implants or nonunion.

Results: Within 6 months of original fixation, 16 of 129 fractures (12%) required reoperation for loosening or breakage of implants (n = 8) or nonunion (n = 8).

We report the case of a 61-year-old woman who was referred to our service after she received a total hip implant at another institution and was found to have a large acetabular defect from pulmonary metastasis. The patient elected to undergo palliative surgical curettage and fixation. We describe a technique to create a cement construct reinforced with Steinmann pins that reduces pain and offers improved mobility.

The most effective way to teach and assess a resident's knowledge of musculoskeletal medicine, including orthopedic-specific surgical skills, remains unclear. We designed a surgical skills training session to educate junior-level orthopedic residents in 4 core areas: comfort with basic power equipment, casting/splinting, suturing, and surgical instrument identification. As part of the study reported here, 11 orthopedic residents (postgraduate year 1-3) completed a skills session and were evaluated with written examinations and an ankle fracture model before and after the session.

Purpose: This study aimed to determine the ability of patients to return to activity after medial patellofemoral ligament (MPFL) reconstruction or repair for patellar instability.

Methods: A systematic review was performed using multiple databases. Studies reporting outcomes with Tegner scores after repair or reconstruction of the MPFL were included.

Soft tissue sarcomas have a mortality rate of 40% to 60%, with local recurrence being a poor prognostic factor for overall survival. Three-percent nondiluted hydrogen peroxide is hypothesized to be an effective local adjuvant. The purpose of this study was to identify risk factors for local recurrence in high-grade soft tissue sarcomas and to determine whether using hydrogen peroxide as a local adjuvant reduced the risks of local recurrence and surgical-site infection.

Background: Magnetic resonance imaging (MRI) is widely used as a preoperative tool to estimate the size of articular cartilage defects to optimize treatment selection. However, the reliability of MRI sizing of cartilage defects is not well understood. Hypothesis/

Purpose: The purpose of this investigation was to compare the size of knee articular cartilage defects on MRI to arthroscopic visualization after debridement.

Article Synopsis
  • The study aimed to assess clinical outcomes of isolated capitellar fractures through a systematic review of existing medical reports.
  • A total of 28 studies involving 174 patients were included, with findings indicating that these fractures are more common in women and typically occur in the nondominant arm.
  • Both nonoperative and operative treatments resulted in satisfactory outcomes, with no significant differences in recovery between the two management strategies.
