ABSTRACT
Objective To compare the morphological variation of the fibular malleolar groove and fibrocartilaginous ridge injury in those with and without peroneal tendon dislocation using MRI.Methods Data of 45 patients (40 males,5 females;average age 23.4±7.7 years,11-44 years) with recurrent peroneal tendon dislocation treated from April 2010 to July 2017 and 45 patients (33 males,12 females;average age 41.6± 11.8 years,17-67 years)without dislocation treated from June 2015 to September 2017 were retrospectively analyzed.The morphological variation of the fibular malleolar groove and fibrocartilaginous ridge injury were compared between the two groups according to Rosenberg's classification (convex,the posterior cortex of the fibula bulges outward;concave,the posterior fibular surface has a shallow-to-deep depression;fiat,neither concavity nor convexity is found).Results In group of patients with recurrent peroneal tendon dislocation:concave,10 patients (22.2％,10/45);fiat,27 patients (60.0％,27/45);convex,8 patients (17.8％,8/45);fibrocartilaginous ridge injury,44 patients (97.8％,44/45).In group of patients without peroneal tendon dislocation:concave,16 patients (35.6％,16/45);flat,18 patients (40.0％,18/45);convex,11 patients (24.4％,11/45);fibrocartilaginous ridge injury,13 patients (28.9％,13/45).Conclusion According the results,significant difference has not been found in morphologic variations of the fibular malleolar groove between patients with and without recurrent peroneal tendon dislocation.Fibrocartilaginous ridge injury is common in MRI of patients with recurrent peroneal tendon dislocation.
ABSTRACT
Objective@#To investigate clinical outcomes of modified reattachment of superior peroneal retinaculum (SPR) for patients with recurrent peroneal tendon dislocation.@*Methods@#A total of 24 cases with recurrent peroneal tendon dislocation from December 2012 to June 2017 were treated with modified reattachment of SPR. There were 20 males and 4 females. The average age was 24.9±9.3 years (14-48 years). The average BMI was 23.18±3.50 kg/m2 (15.8-32.2 kg/m2). A 4-5 cm incision was made along the lateral margin of the fibula and curved distally around the fibular tip in line with the peroneal excursion. The superior peroneal retinaculum, peroneus longus and peroneus brevis were exposed. The periosteum and SPR were stripped from the fibula. The false pouch was formed. Two suture anchors were inserted into the postero-lateral ridge of the lateral malleolus without damaging the cartilaginous ridge, after which the SPR was reattached to the lateral malleolus with the anchored suture. The inner layer of the false pouch was incised, while the outer layer (periosteum) was sutured with the SPR in a pants-over-vest style. The following items, including American Orthopaedic Foot and Ankle Society (AOFAS) score, visual analogue scale (VAS), rate of return to previous sports level, time to return to sports activity, complication, and patients satisfaction were evaluated preoperatively and at the final follow-up.@*Results@#The average operation duration was 36.1±8.8 min (20-51 min). The blood loss was 1-10 ml, average 4.1±2.7 ml. The follow-up was carried out in 22 cases for mean 33.9±15.7 months (13-61 months). AOFAS score was improved from 77.8±7.8 points to 95.5±4.3 points significantly (t=-11.89, P<0.001). VAS score was reduced from 4.2±2.4 to 0.3±0.8 significantly (t=7.69, P<0.001). Mean duration return to sports activity was 5.0±1.9 months (3-10 months). A total of 20 patients (91%) returned to their previous sports level. Only one patient (5%) was found with limitation of range of motion, while two patients (9%) reported pain at the scar site without recurrence. The satisfaction rate was 91%.@*Conclusion@#Clinical outcomes of modified reattachment of SPR for patients with recurrent peroneal tendon dislocation was safe and effective.

In group of patients without peroneal tendon dislocation: concave, 16 patients (35.6%, 16/45); flat, 18 patients (40.0%, 18/45); convex,11 patients (24.4%, 11/45); fibrocartilaginous ridge injury, 13 patients (28.9%, 13/45).@*Conclusion@#According the results, significant differ-ence has not been found in morphologic variations of the fibular malleolar groove between patients with and without recurrent pero-neal tendon dislocation. Fibrocartilaginous ridge injury is common in MRI of patients with recurrent peroneal tendon dislocation.
ABSTRACT
Objective To investigate a simple effective method of hair transplantation, and to explore tech-niques to increase the density and viability of the transplanted. Methods Under a low temperature environment,21 cases were treated with the knife needle technique. 13 cases were used microsugical technique. Results Transplanted hair in each case grew well,of all the 21 patients treated, 18 cases were followed up for a period of time from 5 to 18 months, the transplanted hair covered the bald and scar area well-proportionately with a appearance close to nature. Conclusion The above-mentioned technique is a simple, fast and effective method with less bleeding and injury, and may be used in primary hospital. Combined use of microsugical technique could help to increase the viability and den-airy of the transplanted hairs.
ABSTRACT
Objective To observe clinical effects in treatment of skin extensive laceration.In order to find the best method to treat scrious skin avulsion.Methods In 137 cases,we adopt five ways to treat serious skin avulsion.Results The total effective rate was 94.2%,the out-look and function in injury areas got satisfied recovery after treating.Conclusion The skill of subcutaneous vessel network thin flap is one of the best methods to treat scrious skin avulsion.
ABSTRACT
Objective To sum up transplantation of forearm skin flap to repair the whole defect of the lip.Method Forearm free skin flap was used to repair the whole defect of the lip in 5 cases. Results The treatment was completed in one stage and the results were satisfactory in 5 cases.And the reconstructed lip showed good shape.Conclusions Forearm skin flap has many strong points:the skin flap has big area and wide blood vessel diameter.It is successed easy to be identical,operation can be completed once, and don't suffered harm to face or neighbour supply area.The skin flap has safe grain,more thinner, good springy and similar colour.It plays an important role in the repairs of the whole defect of the lip with nearby skin soft tissue defect.
