    Description of Event or Problem · 1

    THIS REPORT IS BEING FILED AFTER THE REVIEW OF THE FOLLOWING JOURNAL ARTICLE: KLONZ A, HABERMEYER P (2007). ARTHRODESIS OF THE SHOULDER. A NEW AND SOFT-TISSUE-SPARING TECHNIQUE WITH A DEEP LOCKING PLATE IN THE SUPRASPINATUS FOSSA. DER UNFALLCHIRURG. VOLUME 110. NUMBER 10. PAGE 891-895. (GERMANY). THIS STUDY PRESENTS AN OPERATIVE TECHNIQUE THAT HAS NEVER BEEN DESCRIBED BEFORE WHICH COMBINES INTRA AND EXTRA-ARTICULAR ARTHRODESIS WITH PRIMARY COMPRESSION OF THE ARTHRODESIS SPACE USING SCREWS AND AN ADDITIONAL FIXED-ANGLE NEUTRALIZATION PLATE. THIS IS A CASE REPORT OF THE (B)(6) YEAR-OLD FEMALE PATIENT WHO UNDERWENT AN OPEN ACROMIOPLASTY AND AN OPEN REVISION OF THE SUPRASCAPULAR NERVE 5 YEARS PREVIOUSLY. THE OPERATION LED TO A MASSIVE SUBSTANCE DEFECT TO THE ACROMION AND PARALYSIS OF THE SUPRASPINATUS AND INFRASPINATUS MUSCLES, AS WELL AS A DELTOID INSUFFICIENCY. A RECONSTRUCTION ATTEMPT WAS CARRIED OUT USING A DELTOID TRANSPOSITION FLAP. IN 2003, GIVEN THE ONGOING SEVERE PAIN AND INCREASING ALGODYSTROPHY, THE PATIENT UNDERWENT AN INITIAL ARTHRODESIS WITH SMALL FRAGMENT SCREWS AND FIXED-ANGLE BOLTS USING AN UNKNOWN SYNTHES PROXIMAL HUMERAL INTERNAL LOCKING SYSTEM (PHILOS) PLATE. THIS CREATED A SATISFACTORY LEVEL OF STABILITY ¿ THE PATIENT¿S PAIN IMPROVED CONSIDERABLY, BUT DID NOT COMPLETELY DISAPPEAR. FOR THE LAST YEAR, SHE HAS BEEN COMPLAINING AGAIN OF INCREASING, AND RECENTLY, SEVERE PAIN EVERY TIME SHE MOVES HER BODY. SCANS SHOWED A PSEUDARTHROSIS WITH NO BREAK IN THE SMALL FRAGMENT SCREWS. PATIENT UNDERWENT REVISION WITH THE REMOVAL PHILOS PLATE. THE REMOVAL WAS DIFFICULT AS SOME SCREWS WERE COLD-FUSED AND NEEDED TO BE DRILLED OUT. THE SCREWS WERE PARTLY LEFT IN THE BONE IN ORDER NOT TO FURTHER WEAKEN THE BONE BED. THE PATIENT WAS THEN IMPLANTED WITH AN UNKNOWN SYNTHES 4.5-MM LOCKING COMPRESSION PLATE. POST-OPERATION, THE PATIENT WAS COMPLETELY PAIN-FREE. AFTER 3 MONTHS, THE ARTHRODESIS WAS BUILT UP AS WIDELY AS POSSIBLE AND THE ACTIVE MOVEMENT (30 DEGREES FLEXION AND 30 DEGREES ABDUCTION) WAS SEVERELY LIMITED AGAIN, WHICH WAS ATTRIBUTABLE TO THE PREVIOUS LONG PERIOD OF SUFFERING WITHOUT THE BUILT-UP ARTHRODESIS. THIS REPORT CAPTURES THE REPORTED PROXIMAL HUMERAL INTERNAL LOCKING SYSTEM (PHILOS) PLATE AND SCREWS WITH THE FOLLOWING ADVERSE EVENTS: SEVERE PAIN, PSEUDOARTHROSIS. THIS REPORT IS FOR AN UNKNOWN SYNTHES SCREWS. THIS IS REPORT 2 OF 4 FOR (B)(4).
