Decompression and curettage can result are effective as treatments for large jaw cysts, which are common diseases in the clinic. Based on a treatment used in a previous study, this paper proposes a "three-step method" to treat large jaw cyst and repair the bone defect by decompression, curettage, and autologous dental bone powder implantation. This paper introduces the processes and key points of the operation involved in the abovementioned method.

OBJECTIVE: To evaluate clinical effect of autogenous iliac bone graft in treating osteochondral lesion of the talus with subchondral cyst. METHODS: Twenty-two osteochondral lesion of talus patients with subchondral cyst were collected from January 2011 to December 2014, including 18 males and 4 females aged from 34 to 58 years old with an average of (46.4± 6.9) years old. All patients manifested pain and swelling of ankle joint, 7 patients manifested partially limited activity of ankle joint, 2 patients manifested unstable of ankle joint, and 2 patients manifested poor force line of foot. All lesions located on the medial side of talus dome. The area of cartilage injury ranged from 64 to 132(101.6±27.1) mm2, and diameter of subchondral cyst ranged from 9 to 15(10.5±1.8) mm. VAS score and AOFAS score were used to evaluate pain releases and recovery of ankle joint function before operation, 12 and 24 months after operation. Healing condition of autograft was assessed under arthroscopy after removal of internal fixation at 1 year after operation. RESULTS: All patients were followed up from 24 to 60 months with an average of(42.5±9.9) months. Postoperative MRI at 12 months showed autograft healed well but little cyst still seen. Bone grafting and talus healed well, and formation of fibrocartilage well under arthroscopy. Postoperative MRI at 24 months showed combination of bone grafting and surrounding bone well, and small cyst could seen but less than before. VAS score at 12 months after operation 2.8±0.8 was less than that of before operation 6.2±1.5, but had no differences compared with 24 months after operation 2.6 ±0.8 (>0.05). AOFAS score at 12 months after operation 83.0±5.6 was less than that of before operation 55.3±13.7, but had no differences compared with 24 months after operation 83.7±6.6(>0.05). CONCLUSIONS Autogenous iliac bone graft in treating osteochondral lesion of the talus with subchondral cyst could have a good synosteosis and fibrous cartilage on surface, and relieve clinical symptoms.

OBJECTIVETo compare technique and clinical effect of arthroscopic and conventional sectional therapy for the treatment of ischial tuberosity cyst.

METHODSFrom May 2014 and September 2016, 49 patients with symptomatic ischial tuberosity cyst were randomized divided into arthroscopic group and conventional section group by envelope method. There were 24 patients in arthroscopic group, including 16 males and 8 females aged from 42 to 81years old with an average age of (64.1±9.3) years old;the courses of disease ranged from 2 to 36 months with an average of (17.0±9.1) months;treated with removing cyst wall under arthroscopic and build artificial lacuna around cyst. There were 25 patients in conventional section group, including 11 males and 14 females aged from 47 to 79 years old with an average of (61.2±10.6) years old; the courses of disease ranged from 4 to 36 months with an average of (17.5±8.5) months;treated with cutting off lump with transverse incision. Operative time, blood loss, fluid volume, hospital stays and postoperative complication were observed and compared, VAS score were applied to evaluate pain degree.

RESULTSForty-nine patients were followed up from 6 to 18 months with an average of (11.3±3.3) months. In conventional group, 2 patients occurred incision infection, 1 case reoccurred. All patients in arthroscopic group were healed at stage I. Operative time, blood loss, fluid volume, and hospital stays in arthroscopic group were (54.7±7.7) min, (20.8±3.5) ml, (20.3±5.6) ml, (2.8±0.6) d respectively and better than that of conventional group(71.8±8.8) min, (67.3±12.0) ml, (103.6±20.3) ml, (7.8±2.9) d. Postoperative VAS score in arthroscopic group on the first day, seventh days and first month were 2.6±0.7, 0.5±0.6, 0.3±0.5, and significantly lower than that of conventional group 6.0±0.7, 3.0±1.0, 1.1±1.0 respectively(<0.05). There were no statistical difference in postoperative complications between two groups(>0.05).

CONCLUSIONSCompared with conventional group, arthroscopic for ischial tuberosity cyst has advantages of minimal invasive, less blood loss during perioperative period, less pain degree after surgery, safety and rapid recovery. But arthroscopic skills are needed for surgeons. It should be recommended in clinical practice.

Intraosseous ganglion cyst of the carpal bones represents a rare cause of wrist pain. We report a case of a 42 year-old, right-handed female, who presented with pain of the right wrist following a fall on the palm of the hand. Clinical study revealed a moderate swelling over the mid-section of the palmar face and pain through extreme ranges of motion of the wrist. Plain radiographs and CT-scan of the wrist have revealed an intraosseous ganglion cyst of the lunate bone. Curetting-filling by Kuhlman's vascularized radial bone graft allowed a good functional recovery. The clinical, radiological and therapeutic aspects are discussed.

Aneurysmal bone cyst of mastoid bone is seldom, here one case was reported. The mastoid bone of the patient presented with a baloon-like swelling full of non-coagulated blood and serous-hemorrhagic fluid. CT scan demonstrated a large expansile destructive mass located in left mastoid bone region with the thin or absent cortical bone. The MRI demonstrated T2-weighted images and clear boudary from surrounding tissue. Pathologic reported that the mastoid bone was repalcement with lacunar divided by fibro-tissue, containing numerous hemosiderin, giant cells and inflammatory cells. A surgery was performed and the patient was cured.

BACKGROUND: The treatment of simple bone cysts (SBC) in children varies significantly among physicians. This study examined which procedure is better for the treatment of SBC, using a decision analysis based on current published evidence. METHODS: A decision tree focused on five treatment modalities of SBC (observation, steroid injection, autologous bone marrow injection, decompression, and curettage with bone graft) were created. Each treatment modality was further branched, according to the presence and severity of complications. The probabilities of all cases were obtained by literature review. A roll back tool was utilized to determine the most preferred treatment modality. One-way sensitivity analysis was performed to determine the threshold value of the treatment modalities. Two-way sensitivity analysis was utilized to examine the joint impact of changes in probabilities of two parameters. RESULTS: The decision model favored autologous bone marrow injection. The expected value of autologous bone marrow injection was 0.9445, while those of observation, steroid injection, decompression, and curettage and bone graft were 0.9318, 0.9400, 0.9395, and 0.9342, respectively. One-way sensitivity analysis showed that autologous bone marrow injection was better than that of decompression for the expected value when the rate of pathologic fracture, or positive symptoms of SBC after autologous bone marrow injection, was lower than 20.4%. CONCLUSIONS: In our study, autologous bone marrow injection was found to be the best choice of treatment of SBC. However, the results were sensitive to the rate of pathologic fracture after treatment of SBC. Physicians should consider the possibility of pathologic fracture when they determine a treatment method for SBC.

We report the case of a patient with a painful subcutaneous nodule, measuring 13 mm × 17 mm, at the pretibial graft aperture site, which presented two years after a successful anterior cruciate ligament reconstruction with an autologous hamstring graft. A bioabsorbable poly-L-lactide interference screw was used for graft fixation at the tibial aperture. The patient underwent surgical excision of the lesion and curettage at the tunnel aperture. Grossly, extruded fragments of the screw and a thick pseudocapsule of surrounding tissue were excised. There was no communication between the tunnel aperture and the knee joint. The graft was also intact. Histological analysis revealed fragments of the bioabsorbable material in association with fibrous and granulomatous chronic inflammatory cells. This was consistent with a foreign body reaction. The patient subsequently recovered and resumed preinjury level of activity. To the best of our knowledge, this is the first report describing a nodular granulomatous type reaction to foreign bioabsorbable poly-L-lactide screw material subsequent to an anterior cruciate reconstruction surgery.
