Teaching Patients How to Reduce a Shoulder Dislocation: A Randomized Clinical Trial Comparing the Boss-Holzach-Matter Self-Assisted Technique and the Spaso Method.

BACKGROUND: There are many different techniques for reducing acute anterior dislocations of the shoulder, and their use depends on surgeon preference. The objective of this study was to compare the pain experienced by a patient performing a self-reduction technique with the pain felt during a reduction performed by a trained physician. METHODS: The study was carried out at the emergency department of a tertiary referral center. Patients between 18 and 60 years of age with an acute anterior shoulder dislocation were randomly allocated into 2 groups. In 1 group the emergency doctor actively guided the reduction process with the Spaso technique (Sp group), and in the other group the patient used the Boss-Holzach-Matter (also known as Davos or Aronen) self-reduction technique (BHM group). The pain experienced by the patient during the reduction was recorded by means of a visual analogue scale (VAS) ranging from 0 to 10. Other recorded data included demographic characteristics, reduction time, and success rate. RESULTS: Of 378 patients assessed for eligibility from May 2015 until February 2017, 197 did not meet the inclusion criteria, 58 met exclusion criteria, 22 declined to participate, and 41 withdrew before randomization. Sixty acute anterior shoulder dislocations were randomized into the Sp group (n = 30) or the BHM group (n = 30). The BHM group experienced significantly less pain during reduction than the Sp group (p = 0.047), with mean pain scores of 3.57 (standard deviation [SD] = 2.1]) and 5.26 (SD = 2.9), respectively. No significant difference between groups was found with respect to reduction time (105 seconds [range, 10 to 660 seconds] in the Sp group and 90 seconds [range, 5 to 600 seconds] in the BHM group; p = 0.6) or success rate (67% and 77%, respectively; p = 0.39). CONCLUSIONS: The self-reduction technique results in less pain than, and is as efficient in achieving reduction of anterior shoulder dislocations as, the Spaso technique. These findings favor the use of the self-assisted method as an effective first-line treatment for shoulder dislocations seen in the emergency department as well as its use by patients with recurrent dislocation.

Enclavado retrógrado en fractura tibial / Retrograde nailing in a tibial fracture

Se describe un caso de fractura abierta de tibia grado iiia con gran conminución y pérdida distal de stock óseo ( cm) con total afectación de la superficie articular tibial y gran inestabilidad de la articulación peroneo-astragalina. El tratamiento realizado consintió en practicar una exhaustiva limpieza, colocándose un enclavado fresado retrógrado calcáneo-astrágalo-tibial con bloqueos proximales y distales, además de una aguja de Kirschner peroneo-astragalina. Se consiguió el cierre primario de la piel. A las 3 semanas se procedió al aporte de injerto óseo autólogo de cresta ilíaca rellenando el defecto óseo, a la reimpactación del clavo endomedular que estaba protuido distalmente y a la dinamización distal. Se consiguió la consolidación del defecto óseo en 16 semanas. Actualmente, el paciente deambula sin dolor con la artrodesis tibio-astragalina consolidada (AU)

We describe a case of a severely comminuted type iiia open tibial fracture, with distal loss of bone stock (7 cm), total involvement of the tibial joint surface, and severe instability of the fibular-talar joint. The treatment performed consisted of thorough cleansing, placing a retrograde reamed calcaneal-talar-tibial nail with proximal and distal blockage, as well as a fibular-talar Kirschner nail. Primary closure of the skin was achieved. After 3 weeks, an autologous iliac crest bone graft was performed to fill the bone defect, and the endomedullary nail, which had protruded distally was reimpacted and dynamized distally. The bone defect was eventually consolidated after 16 weeks. Currently, the patient can walk without pain the tibial-astragal arthrodesis is consolidated (AU)
