Objective To analyze the excision of accessory navicular with reconstruction of posterior tibial tendon insertion on navicular for the treatment of flatfoot related with accessory navicular and to evaluate its effectiveness. Methods Between May 2006 and June 2011, 33 patients (40 feet) with flatfoot related with accessory navicular were treated. There were 14 males (17 feet) and 19 females (23 feet) with an average age of 30.1 years (range, 16-56 years). All patients had bilateral accessory navicular; 26 had unilateral flatfoot and 7 had bilateral flatfeet. The disease duration ranged from 7 months to 9 years (median, 24 months). The American Orthopaedic Foot and Ankle Society (AOFAS) ankle-midfoot score was 47.9 ± 7.3. The X-ray films showed type II accessory navicular, the arch height loss, and heel valgus in all patients. All of them received excision of accessory navicular and reconstruction of posterior tibial tendon insertion on navicular with anchor. Results All patients got primary wound heal ing without any compl ication. Thirty patients (36 feet) were followed up 6-54 months with an average of 23 months. All patients achieved complete pain rel ief at 6 months after surgery and hadgood appearance of the feet. The AOFAS ankle-midfoot score was 90.4 ± 2.0 at last follow-up, showing significant difference when compared with preoperative score (t=29.73, P=0.00). X-ray films showed that no screw loosening or breakage was observed. There were significant differences in the arch height, calcaneus incl ination angle, talocalcaneal angle, and talar-first metatarsal angle between pre-operation and last follow-up (P lt; 0.01). Conclusion The excision of accessory navicular with reconstruction of posterior tibial tendon insertion on navicular is a good choice for the treatment of flatfoot related with accessory navicular, with correction of deformity, excellent effectiveness, and less complications.
Objective To analyze the short-term effectiveness of repairing musculus extensor carpi radialis brevis (ECRB) and extensor digitorum communis (EDC) tendon using suture anchor after debridement of extensor tendon insertion for recalcitrant lateral epicondylitis. Methods Between March 2009 and May 2011, 10 patients (10 elbows) with recalcitrant lateral epicondylitis received repair of the ECRB and EDC tendon to the lateral epicondyle using a single suture anchor after debridement of extensor tendon insertion. There were 6 males and 4 females with an average age of 45.4 years (range, 36-57 years). The dominant elbow was involved in 8 patients and nondominant elbow in 2 patients; there were 4 manual workers and 6 ordinary workers. The disease duration ranged from 8 to 24 months (mean, 12.3 months). All patients had epicondylus lateralis humeri pain, local swelling and tenderness, and positive Mill sign. The average elbow range of motion (ROM) was 11.3°(range, 0-30°) in extension and was 132.5°(range, 120-145°) in flexion. Preoperative MRI showed external humeral epicondylitis in all patients. ResultsPrimary wound healing was obtained in all patients without complications of infection, leakage of joint fluid, and stiffness of elbow. Ten patients were followed up 4 to 23 months with an average of 12 months (more than 12 months in 7 cases). The time to return to work was (3.75 ± 0.95) months for manual workers and was (2.91 ± 0.20) months for ordinary workers, showing no significant difference (t=1.715, P=0.180). Compared with preoperation, the mean visual analogue scale (VAS) score significantly decreased (P lt; 0.05), and Mayo score and the grip strength of dominant and nondominant significantly increased (P lt; 0.05), but no significant difference was found when compared with non-surgical side at last follow-up (P gt; 0.05). At last follow-up, the average ROM was —1.5° (range, 0-—10°) in extension and was 150.5°(range, 140-160°) in flexion. ConclusionTo suture anchor for repairing the ECRB and EDC after debridement is a satisfactory procedure to treat recalcitrant lateral epicondylitis. It can effectively prevent loss of the forearm extensor strength, relieve the pain, recover the grip strength, and obtain good results.
