    THIS REPORT IS BEING FILED AFTER THE REVIEW OF THE FOLLOWING JOURNAL ARTICLE: HUBER H, HAEFELI M, DIERAUER S, RAMSEIER L (2009). "TREATMENT OF REDUCED FEMORAL ANTETORSION BY SUBTROCHANTERIC ROTATIONAL OSTEOTOMY." ACTA ORTHOPAEDICA BELGICA. VOLUME 75. PAGE 490-496. (SWITZERLAND). THE PURPOSE OF THIS RETROSPECTIVE STUDY WAS TO EVALUATE BONE HEALING AND COMPLICATION RATE AFTER SUBTROCHANTERIC ROTATIONAL OSTEOTOMY FIXED WITH THE ANGLE STABLE LOCKING COMPRESSION PLATE (LCP, SYNTHES), WITH FULL WEIGHT-BEARING ALLOWED POSTOPERATIVELY. BETWEEN JULY 2004 AND OCTOBER 2007, 25 PATIENTS (11 GIRLS, 14 BOYS) AGED BETWEEN 9 AND 18 YEARS (MEAN 13.0 YEARS) WITH REDUCED FEMORAL ANTETORSION WERE TREATED WITH A SUBTROCHANTERIC ROTATIONAL OSTEOTOMY. 4 PATIENTS WERE EXCLUDED FROM THE PRESENT STUDY DUE TO OTHER SIMULTANEOUS SURGERY PROHIBITING IMMEDIATE POSTOPERATIVE FULL WEIGHT BEARING. THEREFORE, 21 PATIENTS WITH A TOTAL OF 33 OSTEOTOMIES WERE INCLUDED IN THIS RETROSPECTIVE STUDY. ALL PATIENTS WERE IMPLANTED WITH AN UNKNOWN SYNTHES LOCKING COMPRESSION PLATE. FULL WEIGHT-BEARING WITH CRUTCHES WAS STARTED ON THE FIRST POSTOPERATIVE DAY IN MOST PATIENTS. FIRST CLINICAL AND RADIOGRAPHIC ASSESSMENT WAS MADE AFTER 6 WEEKS IN ALL BUT ONE PATIENT WHO HAD THE FIRST ASSESSMENT AFTER 8 WEEKS. IMPLANTS WERE REMOVED IN 17 OF THE 21 PATIENTS ABOUT 1 YEAR AFTER PRIMARY SURGERY. COMPLICATIONS WERE REPORTED AS FOLLOWS: 1 PATIENT HAD NOT SHOWN COMPLETE BONE HEALING AFTER 6 WEEKS. THE PATIENT HAD A FOLLOW-UP RADIOGRAPH AFTER 7 MONTHS AND SHOWED COMPLETE CONSOLIDATION AT THAT TIME. 1 PATIENT HAD NOT SHOWN COMPLETE BONE HEALING AFTER 6 WEEKS. THE PATIENT HAD A FOLLOW-UP RADIOGRAPH AFTER 12 MONTHS AND SHOWED COMPLETE CONSOLIDATION AT THAT TIME. 2 PATIENTS HAD SIGNIFICANTLY LESS INGUINAL PAIN AFTER A FOLLOW-UP OF 6 TO 32 MONTHS. 2 PATIENTS HAD MINIMAL KNEE PAIN AFTER A FOLLOW-UP OF 11 TO 20 MONTHS. THIS REPORT IS FOR UNKNOWN SYNTHES SCREWS. THIS IS REPORT 2 OF 2 FOR (B)(4).
