Postoperative management of spontaneous pneumothorax in arthroscopic shoulder superior capsular reconstruction: A case report and review of literature.

Arthroscopic superior capsular reconstruction is an innovative technique for the irreparable rotator cuff tears, but spontaneous pneumothorax after surgery is very rare. The present case was a 66-year-old female with irreparable rotator cuff tears of the right shoulder, treated with the arthroscopic shoulder superior capsular reconstruction. The general anesthesia and operation went smoothly, but the patient experienced stuffiness in the chest and shortness of breath after recovery from anesthesia. Thoracic CT scans showed spontaneous pneumothorax in the right side, which was successfully treated by the conservative treatments (oxygen therapy) according to multidisciplinary team. Prompt and accurate early-stage diagnosis is necessary in controlling postoperative complications and standardized treatment is the key to relieve the suffering. Spontaneous pneumothorax after arthroscopic shoulder surgery has been rarely reported in previous literatures.

Mixed bacterial-fungal infection following total hip arthroplasty: A case report.

Prosthetic infection is one of the severe postoperative complications of arthroplasty. Mixed bacterial-fungal prosthetic infection is rare but can be disastrous. This case was a 76-year-old female suffered from prosthetic infection following total hip replacement due to femoral neck fracture and underwent multiple debridements. The culture of periprosthetic tissue was bacteriologically sterile following the first debridement, while the Staphylococcus hominis was identified in the second debridement in the previous hospitalization where fungal infection had not been considered. Thus the pathogen spectrum of anti-infection therapy failed to contain fungus. Ultimately, the culture result of our sampled periprosthetic tissue during the third debridement was Candida albicans without bacterium in our hospital. The fungal prosthetic infection was successfully treated by a two-stage revision with antifungal drugs. Accurate diagnosis and standardized treatment is the key to the therapy of infection after hip arthroplasty, especially for mixed bacterial-fungal prosthetic infection.

Triple Hemisection Percutaneous Achilles Tendon Lengthening for Severe Ankle Joint Deformity.

OBJECTIVE: To investigate the efficacy of modified percutaneous Achilles tendon lengthening for severe ankle joint deformity. METHODS: This retrospective case series study included 33 patients with an average age of 25.2 years who underwent surgery in our hospital from April 1, 2010 to March 1, 2018. Triple hemisection percutaneous Achilles tendon lengthening was performed. One stage surgery, other soft tissue surgery or bone correction surgery could be performed. After surgery, a plaster cast was used to fix the functional position, and rehabilitation training was carried out as planned. Complications during the perioperative period were recorded. Statistical analysis of the patients' visual analogue scale (VAS) and American Orthopedic Foot and Ankle Society (AOFAS) score before and at the last follow-up was performed. The recurrence rate of Achilles tendon contracture at the last follow-up and the patients' satisfaction rate were investigated. RESULTS: All patients were followed up, with an average follow-up period of 56.31 months (8-104 months). All achieved good ankle joint function and appearance improvement And there were no infection or skin necrosis complications. In two cases, the incision was poorly healed at non-Achilles tendon site and was cured by change of dressing. The average VAS score at the last follow-up was reduced from (2 ± 1.48) points before surgery to (0.26 ± 0.51) points (P = 0.001), and the average AOFAS score was increased from (64.97 ± 13.56) points before surgery to (90.06 ± 10.06) points (P = 0.001). During the follow-up period, there was no chronic rupture of Achilles tendon. There were two cases of recurrence of foot drop (5.7%), and the patients' satisfaction rate was 93.9%. CONCLUSION: In the surgical treatment of severe ankle joint deformity, the application of triple hemisection percutaneous Achilles tendon lengthening for Achilles tendon contracture has the advantages of less trauma, beautiful incision, and reliable efficacy. The satisfaction rate of patients with this treatment is high, and it is worth promoting in the clinic.

V-Y Tendon Plasty for Reconstruction of Chronic Achilles Tendon Rupture: A Medium-term and Long-term Follow-up.

OBJECTIVE: To evaluate the surgical results of V-Y tendon plasty in the treatment of chronic Achilles tendon rupture during medium and long-term follow-up. METHODS: Between June 2005 and September 2017, 20 patients with chronic Achilles tendon rupture underwent V-Y tendon plasty in our hospital. The mean injury-to-surgery time was 20.4 weeks (range, 4-96 weeks). The Matles test and an improved Thompson test was used to examine Achilles tendon rupture. These patients were not able to stand on the tiptoes of the injured lower extremity. X-ray tests ruled out the chance of fracture and were used to examine the Kager triangle. MRI was used to confirm the final diagnosis. The function of the ankle and the foot was assessed using the American Orthopaedic Foot & Ankle Society (AOFAS) score and the Achilles Tendon Total Rupture Score (ATRS). V-Y tendon plasty for Achilles tendon reconstruction was performed. A below-knee cast was used to keep the ankle in plantar flexion (up to 20°) for 4 weeks. Non-weight-bearing exercise was allowed with crutches. After 4 weeks, partial weight-bearing was allowed. Physical exercises were performed under rehabilitation guidelines. At 10-12 weeks postoperation, patients began to return to daily life activity levels without restrictions. Preoperative and postoperative MRI was obtained. RESULTS: The mean follow-up period was 32.8 months. The mean operative gap of the Achilles tendon after debridement was 5 cm (range, 4-9 cm), with 85% of the gap less than or equal to 6 cm. The mean AOFAS score increased from 59.25 ± 12.28 preoperatively to 96.55 ± 3.75 at final follow-up (P < 0.05). The mean ATRS score increased from 39.55 ± 14.21 preoperatively to 94.05 ± 4.89 at final follow-up (P < 0.05). All patients had no recurrent Achilles tendon rupture during the follow up. No patient had developed serious complications, such as sural nerve injury or deep vein thrombosis. Patients were able to return to daily life activity levels without restrictions. At the latest follow-up, all patients were able to perform repetitive single heel rise on the involved limb, and to walk without a visible limp. All of the postoperative MRI showed the continuity of the Achilles tendon with no signs of cysts or inflammation, indicating perfect healing at the final follow-up. CONCLUSIONS: V-Y tendon plasty can be used in most cases of chronic Achilles tendon rupture. It yields satisfactory functional results and low complication rates. The advantage of this procedure is that it is an easy and economic method without the need for expensive synthetic implants. V-Y tendon plasty should be considered an acceptable first-choice treatment.
