The localized type of tenosynovial giant cell tumor usually occurs on the palmar side of fingers and toes. Tenosynovial giant cell tumors of the tendon sheath are rarely intra-articular. We report a giant cell tumor of the tendon sheath arising from femoral attachment of the anterior cruciate ligament and its treatment with arthroscopy in a 28-year-old man.

OBJECTIVETo investigate surgical methods and therapeutic effects of giant cell tumor of tendon sheath in finger.

METHODSFrom July 2002 to December 2010,70 patients with giant cell tumor of tendon sheath in finger which confirmed by operation and pathology,were retrospectively analyzed. There were 29 males,41 females with an average of 42 years (ranged, 16 to 61), and the course of disease ranged form 4 months to 6 years (mean 11 months). The method of surgery and anesthesia were observed.

RESULTSAll wounds were got stage I healing,no necrosis occurred. Vascular crisis occurred in 6 cases (8.6%), inconformity of diagnosis in 18 cases (25.7%), changing of anesthesia due to situation of tumor in operation in 17 cases (24.3%). The patients were followed up from 2.2 to 10.5 years. Among them, 8 cases (11.4%) recurred, and diagnosied by the second operation without malignant change.

CONCLUSIONThe best anesthesia for giant cell tumor in finger should choose brachial plexus to fully expose,complete resection and less harmful damage; while the operation should complete resection at the stage I, and followed up actively, the second operation can be carried out for recorrenced.

A 38-year-old man presented with right knee pain and swelling following a football injury. Magnetic resonance (MR) imaging showed a complete anterior cruciate ligament (ACL) tear and lateral meniscal tears. The torn ACL was repaired with a graft obtained from the semitendinosus muscle, and the menisci were debrided. The mechanisms of injury to the ACL are varied and may be due to direct or indirect contact with the knee as well as with twisting injuries. Knowledge of the ACL's normal anatomy, together with MR imaging technique and understanding of the appearance of the lesion on MR examination, is crucial to aid in the identification of an ACL tear. Diagnosis of an ACL tear should be based on direct MR imaging signs, although indirect signs may be helpful, particularly in chronic tears. Other associated injuries to be aware of include meniscal and other ligamentous injuries. Normal ACL graft and post-ACL graft reconstruction complications are also briefly discussed.

OBJECTIVETo investigate diagnostic methods and surgical effect for the treatment of giant cell tumor of tendinous sheath in wrist.

METHODSFrom September 2002 to October 2009, 8 patients with preoperative diagnosis as giant cell tumor of tendinous sheath based on MRI were treated surgically. There were 5 males and 3 females, ranging in age from 16 to 65 years, with an average of 41 years. The disease course ranged from 10 to 72 months with an average of 31 months.

RESULTSThe diagnosis of all the patients was confirmed as giant cell tumor of tendinous sheath by postoperative pathology. All the patients were followed up, and the during ranged from 5 to 48 months (averaged, 34.2 months). One patient recurred and 3 patients got obvious relief of symptoms of median nerve injury. All the patients had significant improvement in wrist function after surgery.

CONCLUSIONPreoperative MRI is helpful for differential diagnosis of giant cell tumor of tendinous sheath. Thorough removal of tumor is very important in prevention of recurrence.

OBJECTIVETo study the relation of the sex, age, location and chemotherapy with recurrence of the tumor.

METHODSFrom January 2000 to August 2010, 47 patients with giant cell tumor of tendon sheath in upper extremity were retrospectively analyzed. Statistical analysis of sex, age at presentation, lesion location, chemical inactivation, surgical complications, tumor recurrence and pathological findings were explored. There were 28 females and 19 males, ranging in age from 17 to 78 years, with an average of 38.15 years. All the patients underwent surgical excision. Fourteen patients received intraoperative chemically inactive treatment. All the patients had routine follow-up to observe the wound healing, pathological findings,tumor recurrence, and received necessary imaging examinations.

RESULTSAll the patients were followed up, and the duration ranged from 22 to 129 months, with a mean time of 53.89 months. Four patients who received intraoperative alcohol inactivation appeared wound complications such as wound swelling, discharge of necrotic tissue, delayed wound healing. Fifteen patients had active growth of tumor tissue, 1 patient had low-grade malignant giant cell tumor of tendon sheath. The recurrence rate was significantly higher in the group which preoperative X-ray was found to have bone destruction (P = 0.003); patients receiving chemically inactivation had lower risk of recurrence after surgery than patients not receiving chemically inactivation (P = 0.042).

CONCLUSIONThe recurrence rate of giant cell tumor of tendon sheath in upper limb was closely related to tumor growth site, bone destruction and chemical inactivation. Local excision of giant cell tumor of tendon sheath was the effective treatment. How to identify the patients at high risk of recurrence, how to reduce the recurrence rate and the functional restoration after wide resection are the priorities and difficulties of future researches.

This investigation was to study the effects of cage-squeezing screw on tendon-bone healing in rabbits. The tendons of Twenty four rabbits were severed and fixed with cage-squeezing screw or ordinary squeezing screw on its tibia, and the interface of tendon-bone was tested at the ends of 3, 6 and 12 weeks after operations, respectively. The cage-squeezing screw can accelerate bone tunel healing and strengthen the graft intension. The experiments proved that the cage-squeezing screw could help the restructuring process of the graft after the beginning of reconstruction.

OBJECTIVESTo measure the size and change of bone tunnel in arthroscopic assisted anterior cruciate ligament (ACL) reconstruction with hamstring tendon autograft by X-ray, and evaluate the incidence, extent, shape and reasons of the bone tunnel expansion and analyze the relationship between bone tunnel expansion and clinical results.

METHODSFifty-one cases of arthroscopic ACL reconstruction with hamstring tendon autograft were performed, and they were followed up at average of 16 months postoperatively. The diameter, shape, position and angle of femoral and tibial bone tunnel were measured using X-ray, and other clinical information had been collected including gender, age, method of tibial fixation, range of motion, KT 2000 and evaluation of muscle strength and so on. All data were entered into the computerized relational database to analyze and compare using the chi square test and correlation analysis.

RESULTSThe incidence of tunnel expansion after ACL reconstruction was 85%-94% in femoral tunnel and 65% in tibial tunnel. The extent of tunnel expansion was 51%-53% in femoral tunnel and 40%-44% in tibial tunnel. The most common shape of tibial tunnel was type O in the A-P X-ray view and type V in the lateral X-ray view. Femoral tunnels anterior to the expected ones were more likely to enlarge. Tibial tunnels anterior to the expected ones were easier to expand. An acute tibial or femoral tunnel angle could result in the femoral tunnel expansion.

CONCLUSIONSThe incidence and extent of bone tunnel expansion in arthroscopic ACL reconstruction with hamstring tendon autograft are more significant in femoral tunnel than in tibial tunnel. Bone tunnel expansion is correlated to patients' age, height, BMI and location of the tunnel. The main factors related to bone tunnel expansion are the location and angle of the tunnel.
