ObjectiveTo summarize the clinical characteristics and treatment of acute cellulitis of shank after total knee arthroplasty. MethodsWe retrospectively analyzed the clinical data of five patients with delayed acute cellulitis of shank after total knee arthroplasty treated in our hospital between January 2008 and January 2013. The clinical characteristics, treatment and prognosis of the disease were then summarized and analyzed. ResultsThe delayed acute cellulitis of shank after total knee arthroplasty was mainly caused by tinea pedis, which resulted in skin damage and bacteria diffusion. The main clinical manifestations were pain and swelling around the knee joint and shank. The laboratory test found the increasing of C-reactive protein, erythrocyte sedimentation rate, white blood cell and neutrophils. Two cases were caused by hemolytic streptococcus according to blood culture. All patients were discharged after treatment without periprosthetic infection. ConclusionAccording to the typical clinical manifestations and laboratory test, the diagnosis of delayed acute cellulitis of shank is not difficult. Timely and comprehensive treatment should be emphasized to seek and eradicate the primary lesions, such as tinea pedis, subcutaneous ulcer and carbuncle.
Objective To summarize the cl inical effect of anterolateral thigh pedicle or free perforator flap in repairing soft tissue defect in the extremities. Methods From March 2000 to January 2009, 32 cases of soft tissue defect were treated with pedicle or free anterolateral thigh perforator flap. There were 30 males and 2 females with an median age of28 years (4-53 years). Soft tissue defects included left radial side in 3 cases, the left lateral elbow in 1 case, knee in 5 cases, calf in 14 cases, dorsal is pedis in 5 cases, and planta pedis in 4 cases. The defect area ranged from 9 cm × 6 cm to 15 cm × 13 cm. Nine cases compl icated by bone defect and 1 case by radial nerve defect. The time from injury to hospital ization was 1 hourto 4 months (mean 5 days). Defects in 27 cases were repaired by anterolateral thigh perforator flap, simultaneously combined with transplantation with the second toe in 1 case, with sural nerve using arterial ized small saphenous vein in 1 case, nd with fibular or il ium in 4 cases. Defects in other 5 cases were repaired with flaps pedicled with superior lateral genicular artery. Neuroanastomosis was performed in 14 cases of the flaps. The size of the flaps ranged from 10 cm × 8 cm to 16 cm × 15 cm. Skin defects at donor site were repaired with spl it thickness skin graft or sutured directly. Results All patients were followed up from 8 months to 9 years with an average of 18 months. The flaps survived well and the wounds healed by first intention in 29 cases, 3 flaps necrosed and cured after symptomatic management. Skin graft at donor site survived completely in 9 cases. The color and texture and thickness of the flaps were similar to those of recipient site. After 6 months, the sensation of the flaps recovered to grade S3-4 in 14 patients whose cutaneous nerve were anastomosed, partial recovery was observed in other patients. In 4 patients receiving transplantation of fibular or il ium, the bony heal ing was achieved within 4 to 6 months. No obvious dysfunction was found at the donor site. Conclusion The pedicle anterolateral thigh perforator flap is long and thick with constant location. Anastomosis or transferring is easy to perform. It can provide big area and feel ing recovery by nerve anastomosis. It is an effective method to repair soft tissue defect of the extremities.
Objective To investigate the change of vasa vasorum in vessel wall of varicose vein of the lower extre-mity. Methods Thirty-two patients with varicose vein of the lower extremity were collected， in which of 12 patients with simple varicose veins （varicose group）， 9 patients with recurrent varicose veins （recurrent group）， 11 patients withthrombophlebitis of varicose vein （thrombophlebitis group）， 9 patients with normal venous tissue as control group. HE staining was performed to observe the distribution of vasa vasorum and detect the vasa vasorum density. Results The increasing vasa vasorums were observed in the adventitia and media， but few was observed in the intima in the varicose， recurrent， and thrombophlebitis groups. The distribution of vasa vasorum was in the adventitia in the control group. The vasa vasorum densities （/mm2） in the varicose， recurrent， and thrombophlebitis groups （5.65±1.45，6.20±1.73， and 5.94±1.63， respectively） were greater than those in the control group （2.87±0.54）， the difference wasstatistically significant （P＜0.05）， but there was no significant difference of the vasa vasorum density among the varicosevein， recurrent， and thrombophlebitis groups （P＞0.05）. Conclusion Change of vasa vasorum is an important pathol-gical change with the nosogenis of varicose vein of the lower extremity.
Objective To assess the effectiveness of arthroscopic capsular release to treat primary severe frozen shoulder through trans cuff portal. Methods Between June 2012 and January 2015, 28 patients with primary severe frozen shoulder were enrolled in the study. There were 8 males and 20 females with an average age of 57 years (range, 42-81 years). The left shoulder was involved in 16 cases and the right one in 12 cases. The mean disease duration was 11 months (range, 7-21 months). Six patients had diabetes. All patients underwent arthroscopic capsular release by trans cuff portal. The range of motion (ROM) of the shoulder were measured at preoperation and at 6 weeks and 24 months after operation; the scores of American Shoulder and Elbow Surgeons (ASES) and visual analogue scale (VAS) were used to evaluate the shoulder function and pain. Results Primary healing of incision was obtained, and no complications of infection, shoulder instability, and nerve injury were found. All patients were followed up 24 months. Pain of the shoulder was obviously relieved; VAS score was significantly lower at 6 weeks and 24 months after operation than preoperation (P<0.05), and at 24 months than 6 weeks (P<0.05). ROM of the shoulder and ASES score at 6 weeks and 24 months after operation were significantly increased when compared with preoperative ones (P<0.05); significant difference was found in ROM of forward flexion and external rotation and the ASES score between at 6 weeks and 24 months (P<0.05). And internal rotation in-creased from trochanter (9 cases), hip (6 cases), sacrum (7 cases), and L4 vertebral level (6 cases) before operation to the T12-T6 vertebral level at 6 weeks and 24 months after operation, which were close to normal side. Conclusion Arthroscopic capsular release through trans cuff portal is an effective and safe management for primary severe frozen shoulder.
Objective To prospectively evaluate the health-related quality of life (HRQOL) outcomes in patients undergoing laparoscopic total mesorectal excision (LTME) with anal sphincter preservation (ASP) for low rectal cancers. Methods From June 2001 to March 2004, 125 patients undergoing LTME and 103 patients undergoing OTME were included in this study. The international standard questionnaires (QLQ-C30 and QLQ-CR38) were used to evaluate the conditions of patients at 3 periods after surgery respetively: 3-6 months, 12-18 months, gt;24 months. Results In contrast to OTME patients, the LTME ones showed significantly better physical function during 3-6 months after surgery, less micturition problems within 12-18 months, less male sexual problems and better sexual function during 12-18 months after surgery, with better sexual enjoyment after postoperative 24 months. Both groups showed significant improvement in most subscales from the first to the second assessment, and improvement in sexual enjoyment from the second to the third assessment. The sexual function, micturition problems and male sexual problems in LTME group significantly improved from the first to the second assessment, whereas the sexual function in OTME group improved from the second to the third assessment.Conclusion Patients undergoing LTME for low rectal cancers have bette postoperative HRQOL than patients undergoing OTME, with better physical function, micturition function, overall sexual and male sexual functions in short term, and better sexual enjoyment in the long term. The HRQOL of both LTME and OTME patients may be expected to improve over time, particularly in the first postoperative year.
