BACKGROUND: The impact of high-intensity, repetitive training on the fingers of adolescent climbers is relatively unknown. OBJECTIVE: To evaluate this effect by ultrasound (US) and to confirm some findings by magnetic resonance imaging (MRI). MATERIALS AND METHODS: The US study was performed in 20 adolescent rock climbers (ages 10-17 years) and 6 non-climbing controls (ages 11-15 years). US was used to examine the third digit of the right hand for differences in thickness of soft tissue, flexor and extensor tendon, volar plate and bony and growth plate adaptations...

Distal ulnar fractures often occur with distal radius fractures (DRFs), and ulnar styloid fractures commonly occur in the setting of DRF. However, isolated ulnar head fractures are rare. We report a case of isolated ulnar head fracture in which we performed bone resection because the ulnar head bone fragment fractured when internal screw fixation was attempted. His outcome at 18 months postoperatively was considered excellent. However, we do not advocate bone resection other than failure of fixation and the difficult case to perform internal fixation...

Posterior subtalar dislocation is an exceedingly rare entity. Clinically, the appearance of the foot can simulate a complex fracture dislocation. It is important to recognize that not all posterior subtalar dislocations are true posterior dislocations. We report a true posterior subtalar dislocation in a 34-year-old female, managed promptly with closed reduction and resulting in an excellent functional outcome. A chronic dislocation or an irreducible dislocation may need open reduction.

Jay H Patel, Berton R Moed
BACKGROUND: Exact determinants of hip instability have not been established for fractures of the posterior wall of the acetabulum involving ≤50% of the wall. Therefore, examination of the hip under anesthesia (EUA) is routinely performed. Recently, the superior exit point of the fracture has been reported to be an important identifiable risk factor. Pre-existing adult hip dysplasia (developmental dysplasia of the hip [DDH]) is thought to have a similar role. The purpose of this study was to determine if any known radiographic measurements and signs associated with DDH, or any fracture characteristics, are independent risk factors for hip instability after fracture of the posterior wall of the acetabulum...

BACKGROUND: Implant registries have proved valuable in assessing the outcomes of arthroplasty procedures. Moreover, by identifying lesser quality implants they have indirectly improved the quality of care. The registry of prosthetic shoulder implants was established in 2008. METHODS: It records information on all types of primary and revision arthroplasty procedures involving the glenohumeral joint, including reverse and total arthroplasty, hemiarthroplasty, resurfacing, removal, and any other surgical procedures that are required to manage these patients...

It is not a common case for neurosurgery department and the other departments to perform joint operation at the same time. Patients with severe head injury are a condition in which vital signs are unstable due to severe brain swelling and increased intracranial pressure, and emergency surgery is required. A 44-year-old man visited the trauma center with a motorcycle accident. The Glasgow Coma Scale score at the time of emergency department was 3 points, and the pupil was fixed at 6 mm on both sides. His medical history was unknown...

REVIEW
S Parratte, M Ollivier, J-N Argenson
Relatively poor results have been reported with open reduction and internal fixation of complex fractures around the knee in elderly osteoporotic patients, and primary total knee arthroplasty (TKA) has been proposed as an alternative solution. While limiting the number of procedures, it meets two prerequisites: 1) to save the patient's life, thanks to early weight-bearing, to limit decubitus complications; and 2) to save knee function and patient autonomy, thanks to early knee mobilization. There are 3 main indications: complex articular fractures in elderly patients with symptomatic osteoarthritis prior to fracture; complex articular fractures of the tibial plateau in elderly patients whose bone quality makes internal fixation hazardous; and major destruction of the distal femur in younger patients...

BACKGROUND: Gait instability and muscle rigidity are known characteristics of Parkinson's disease (PD), putting PD patients at risk for complications following total joint arthroplasty (TJA). The outcomes of Parkinson's patients undergoing TJA are largely unknown. This study evaluated the outcomes of TJA in this population. METHODS: A single institution retrospective cohort of 123 TJAs (52 hips, 71 knees) from 2000 to 2016 was reviewed. An electronic chart query was performed using International Classification of Diseases, Ninth revision codes to identify this population...

BACKGROUND: Evaluating patient-reported outcomes (PRO) in early osteoarthritis (OA) of the knee is difficult. Established measurement tools are focused on one of the two major patient groups in knee surgery: young, highly active patients, or older patients with advanced degenerative OA of the knee. Joint awareness in everyday life is a crucial criterion in measuring PRO. The purpose of this study was to validate a German version of the "Forgotten Joint Score" (FJS) in patients after surgical treatment of tibial plateau fractures...

Synovitis is a key contributor to the inflammatory environment in osteoarthritis (OA) joints. Currently, the biological therapy of OA is not satisfactory in multiple single-target trials on anti-TNF agents, or IL-1 antagonists. Systems biological understanding of the phosphorylation state in OA synovium is warranted to direct further therapeutic strategies. Therefore, in this study, we compared the human synovial phosphoproteome of the OA with the acute joint fracture subjects. We found that OA synovium had significantly more phosphoproteins, and 82 phosphoproteins could only be specifically found in all the OA samples...

OBJECTIVES: In this study, we tried to explore the effects of a single condylar neck fracture without condylar cartilage injury during the pathogenesis process of traumatic heterotopic ossification around the temporomandibular joint (THO-TMJ). STUDY DESIGN: One-month-old C57 BL/6 J male mice were divided into 2 groups. In group 1, condylar cartilage was partially removed in the right joint to induce THO. In group 2, a single fracture on the condylar neck was created using small scissors...
