Conditions

Arthrodesis, Osteotomy

Brief summary

This observational study aims to determine the efficacy and safety of the Shark Screw® transplant for osteotomy and arthrodesis in hand and foot surgery.

Detailed description

The Shark Screw® transplant (surgebright GmbH) is a human cortical bone allograft for osteosynthesis and can replace metal or bioabsorbable devices in various procedures. In total, the clinical records from 32 patients who had undergone surgical procedure at the hand or foot between October 2016 and January 2018 with the use of a Shark Screw® transplant for joint arthrodesis or for the stabilization of osteotomies serve as data sources for this study. The aim of this study is to evaluate the efficacy and safety of the Shark Screw® transplant in hand and foot surgery by analyzing the recovery, wound and bone healing process.

Design outcomes

Primary

MeasureTime frameDescription
Osseous consolidation of the transplant1 yearAbsence of radiolucent lines around the transplant in the x-ray
Evaluation pre- and postoperative pain (VAS)1 yearThe visual analogue scale (VAS) is a vertical line, 10 centimeters (100 mm) in length, anchored by 2 verbal descriptors, one for each symptom extremes (0mm = no pain - 100mm = worst imaginable pain). A higher score indicates more pain.

Secondary

MeasureTime frameDescription
Incidence of postoperative pseudarthrosis1 yearBased on x-rays or MRI: Is a postoperative pseudarthrosis visible?
Duration of post-operative analgesic medication1 yearHow long did the patient take analgesics after surgery?
Cellular contact to the recipient bone1 yearAbsence of sclerosis around the transplant in the x-ray
Incidence of postoperative complication and soft tissue irritation1 yearDid wound healing disorder or soft tissue irritation occur?
Incidence of cracking or loosening of the screw1 yearBased on x-rays: Is a loosening or cracking of the screw visible?
Patient satisfaction1 yearPatient satisfaction was classified as very satisfied, satisfied and not satisfied
Resorptive processes in the recipient bone1 yearAbsence of cystic lucency in the x-ray
Incidence of surgical revision1 yearWas a surgical revision done postoperatively?
