ABSTRACT
Objective To compare the effects of arthroscopic surgery plus one or more posterior small incisions and the sinus tarsi approach in the treatment of calcaneal fracture.Methods A retrospective analysis was conducted of the 85 patients with calcaneal fracture who had been treated from January 2017 to June 2017 at Department of Foot & Ankle Surgery,Guangzhou Orthopaedic Hospital.They were 43 men and 42 women,32 to 58 years of age (average,46.0 years).Arthroscopic surgery plus one or more posterior small incisions was performed in 40 of them while the sinus tarsi approach was used in the other 45 cases.The 2 groups were compared in terms of operation time,fracture healing time,incision complications and functions of the affected foot by the American Orthopedic Foot Ankle Society (AOFAS) ankle-hindfoot scores.Results There were no significant differences in the preoperative general data between the 2 groups,showing they were comparable (P ＞ 0.05).The average follow-up period for all the patients was 8 months (from 6 to 12 months).For the arthroscopic surgery group and sinus tarsi approach group,the fracture healing time was 8.6 ± 2.4 weeks and 8.9 ± 1.8 weeks,and the AOFAS ankle-hindfoot scores were 82.5 ± 5.6 and 85.1 ± 4.0,respectively,showing no significant differences between them (P ＞ O.05).The operation time in the arthroscopic surgery group (43.6 ±5.4 min) was significantly less than in the sinus tarsi approach group (56.5 ±6.4 minutes),and the rate of complications in the former[2.5％ (1/40)] significantly lower than in the latter[15.6％ (7/45)] (P ＜0.05).Conclusion Arthroscopic surgery plus one or more posterior small incisions may be a fine treatment for calcaneal fractures because postoperative incision complications can be reduced.
ABSTRACT
BACKGROUND:Lisfranc ligament is the strongest one among three ligaments between the second metatarsal bone and the medial cuneiform, anditis critical for maintaining the stability between the second metatarsal bone and the medial cuneiform because Lisfranc ligament isthreetimes stronger than the dorsal ligament. However, there have been no reportsaddressingthe effects of Lisfranc ligament injury on the stability of tarsometatarsal joints. METHODS/DESIGN:An anatomical and biomechanical study was performed. Anatomical measurements were performed in the origin, terminal, path, length, width, and thickness of Lisfranc ligament utilizing cadaverous embalmed specimens. In the experiment on fresh-frozen cadaveric specimens, the displacement changes between the first and the second metatarsal base under different loading were measured with biomechanical analysis after the successively resected dorsal ligament, Lisfranc ligament, and plantar ligament were loaded, respectively, exploring the effectof Lisfranc ligament on stability of tarsometatarsal joints. DISCUSSION:This study providesthe theoretical basis for the treatment of tarsometatarsal joint injury in the clinic through exploring the effects of Lisfranc ligament on stability of tarsometatarsal joints. The attention should be paid to Lisfranc ligament by the physicians when the tarsometatarsal joint injury occurs.
ABSTRACT
Objective To evaluate the therapeutic effect of minimally invasive retractor reduction and fixation through sinus tarsi approach together with external application of Chinese medicine for displaced intra-articular calcaneal fractures. Methods From October of 2009 to June of 2013, 52 patients with displaced intra-articular calcaneal fractures (Sanders type Ⅱ, Ⅲ) were enrolled into the study. The patients received minimally invasive retractor reduction through sinus tarsi approach and fixation with small plate and cannulated screws, and after the operation were given external washing with Chinese herbal formula Shenxing Fang ( mainly composed of Herba Lycopodii, Herba Speranskiae Tuberculatae, Rhizoma Sparganii, Rhizoma Curcumae, Herba Asari, Radix Aconiti Preparata, Radix Aconiti Kusnezoffii Preparat). Follow-up was carried out for the evaluation of the therapeutic effect of displaced intra-articular calcaneal fractures ( Sanders type Ⅱ, Ⅲ). Results Forty cases (involving 44 feet) received the postoperative follow-up for 12-18 months (average being 14.2 months). The Maryland foot scores were 95 points for type Ⅱ displaced intra-articular calcaneal fractures, and 86 points for type Ⅲ fractures. Satisfactory results were achieved in the height, width and length of the calcaneus as well as the B?hler's and Gissane angle ( P<0.01). Conclusion Minimally invasive retracter reduction and fixation through sinus tarsi approach together with external application of Chinese medicine exert satisfying effect for the treatment of displaced intra-articular calcaneal fractures.
ABSTRACT
Objective To investigate an early diagnostic method and a rapid efficient treatment method to teat osteofascial compartment syndrome(OCS). Methods From January 2007 through December 2008,16 male patients with OCS were treated in our department.They were aged from 15 to 55 years (average,32 years).Twelve patients had OCS at the leg and 4 at the foot.All patients had no vascular or nerval injury.The modified Whiteside method was used to measure the pressue of the osteofascial compartment.All patients were treated with open decompression and vacuum sealing drainage (VSD).After swelling subsided,the wounds were directly sutured,decompresively sutured or treated with skin grafting. Merchant scoring was used to evaluate the postoperative efficacy in terms of limb-affected function,pain,gait,joint function,joint stability and range of motion. Results All patients were followed up for 12 to 14 months (average,13 months).All incisions closed up.Fourteen patients obtained excellent recovery of the function and sensation of the distal limb-affected;one patient had hypoesthesia and numbness at the the distal limb-affected; one patient had contracture,numbness and functional disturbance.By the Merchant scoring system,9 cases were excellent,5 good and 2 fair,giving a good to excellent rate of 87.5％. Conclusions The modified Whiteside method used to meausre the interstitial pressure is a reliable early diagnostic method for OCS.Decompression plus VSD may lead to rapid and efficient treatment of OCS and a reduced disability rate of the limb-affected.
ABSTRACT
Objective To evaluate the therapeutic effect of proximal femoral nail(PFN)and dynamic hip screw(DHS)for intertrochanteric femoral fracture(IFF).Methods From September,2004 to May,2007,39 IFF patients treated by PFN and 36 by DHS were enrolled into the analysis.The operative complications,postoperative complications and the recovery of hip function of IFF patients were observed to evaluate the therapeutic effect of the two methods.Results The blood loss amount was higher,the incidence of postoperative complications was higher and the excellent rate of Harris score of hip function was lower in IFF patients treated by DHS than that in IFF patients by PFN(P
