ABSTRACT
<p><b>OBJECTIVE</b>To investigate the clinical effect of a new bundle-to-bundle suturing method for acute Achilles tendon rupture.</p><p><b>METHODS</b>From April 2013 to January 2015, 15 patients with acute Achilles tendon rupture were treated with a new bundle-to-bundle suturing method including 12 males and 3 females with an average age of 37.5 years old ranging from 27 to 56 years old. All of them were immobilized by cast for 6 weeks on the underlying limbs, and were educated for a rehabilitation training during the follow-up.</p><p><b>RESULTS</b>All the patients were followed up for 9 to 17.5 months with an average of 13.5 months. According to the American Ankle Surgery Association (AOFAS), ankle and foot score was 93.3±3.5 at 6 months after operation. All patients got incomplete weight-bearing at 1.6 months on average after the operation, and back to primary work position 4.7 months later on average. All the wounds got primary healing. No incisional infection, necrosis of incisional marginal necrosis, rupture of the Achilles tendon, and gastrocnemius injury occurred.</p><p><b>CONCLUSIONS</b>The surgical treatment of acute Achilles tendon rupture with bundle-to-bundle suturing method has advantages of mini-invasion, a low rate of incision problems and quick function recovery, and was valuable spread in clinic.</p>
ABSTRACT
<p><b>OBJECTIVE</b>To discuss clinical effects of headless pressure screw with local complication of PRP in treating old metatarsal intra-articular fracture.</p><p><b>METHODS</b>From January 2010 to June 2016, 7 patients with old metatarsal intra-articular fracture treated by open reduction headless compression screw internal fixation by local application PRP, including 5 males and 2 females, aged from 21 to 52 years old, 5 patients injured by falling down and 2 patients caused by crushing, the time from injury to operation ranged from 3 to 6 weeks. Preoperative anteroposterior, lateral and oblique X-ray film and three-dimensional CT reconstruction were examined, and the results showed 2 patients on the second metatarsal, 2 patients on the third metatarsal, 3 patients on the fourth metatarsal. Regular X-ray as postoperative examination was observed, and American Orthopaedic Foot and Ankle Society (AOFAS) ankle scoring system at the final follow-up was evaluated.</p><p><b>RESULTS</b>Seven patients were followed up from 6 to 17 months. All incisions healed at stage I without joint stiffness, traumatic arthritis and related complications. Imaging examination showed fracture reached bone healing, healing time ranged from 3 to 6 months. No joint stiffness and traumatic arthritis occurred. One of seven patients occurred stiffness of metatarsophalangeal joints. AOFAS score increased from 40.5±4.2 before operation to 85.0±10.5 at 12 months after operation, and 4 patients got excellent results, 2 moderate and 1 poor. The active motion of metatarsophalangeal joint showed dorsal flexion ranged from 35° to 40°, plantar flexion ranged from 25° to 35°.</p><p><b>CONCLUSIONS</b>Headless pressure screw with local complication of PRP in treating old metatarsal intra-articular fracture could recover articular surface of metatarsal head, improve metatarsophalangeal joints activity, which do not need the second operation, and could receive good clinical results with early exercise.</p>
