Cryosurgery and Impaction Subchondral Bone Graft for the Treatment of Giant Cell Tumor Around the Knee

Giant cell tumors are neoplasms of mesenchymal stromal cells with varied manifestations. There is no uniform accepted treatment protocol for these tumors. Curettage, although an accepted method of treatment, carries a high local recurrence rate. Adjuvant therapies including high-speed burr debridement, cryotherapy, and phenol treatment have been advocated to reduce local recurrence. We have used these adjuvants to determine if improved cure rate with improved outcomes could be attained with regard to local tumor control and functional outcome. Twenty-eight cases of proven giant cell tumors of the distal femur and proximal tibia were included in this prospective case series. The lesions were at the upper tibia in 14 cases and the lower femur in 14 patients. The patients were evaluated clinically, radiologically, and by histological examination. Companacci grading and Enneking staging were determined. The treatment was done in the following steps: Curettage and further debridement with a high-speed burr, cryotherapy, impaction of the cavity with subchondral iliac crest bone graft, and, finally, cementation with or without internal fixation. Functional evaluation was done by Enneking’s system. The follow-up time was between 24–40 months with a mean of 34 months. The functional results of the procedure were rated as good to excellent with a mean of 93.9%. This technique has the advantages of joint preservation, excellent functional outcome, and low recurrence rate when compared with other treatment modalities. For these reasons, it is recommended as an adjuvant to curettage for most giant cell tumors of bone.     

Influence of Smoking in the Clinical Outcomes of Distal Radius Fractures

Introduction  There are various studies that reviewed the effect of cigarette smoking in fracture healing process. Nonunion, delayed union, and residual pain are the significant risk factors associated with smoking and fracture healing. Little has been known about the impact of smoking in distal radius fracture healing. We intend to explore in brief the effect of smoking in distal radius fracture healing and comparing it with nonsmokers having the same fracture fixation and analyze the outcomes with respect to fracture healing and return of function. Materials and Methods  Of the total 186 patients, 92 were included in the study with ( n = male: 31, female: 61) mean age of 60.2 years. They were divided into two groups: smoking ( n = 43) and nonsmoking ( n = 49). All had surgical fixation of the distal radius with volar locking plate and started on early mobilization. The range of motion of the wrist, grip, visual analog scale, quick disabilities of the arm and shoulder and hand score, Mayo wrist score, and bone healing period were noted between these two groups and compared with statistical analysis. Results  The mean follow-up period was 8.7 months. There was a significant association of young age and male patients having distal radius fractures in the smoking group ( p < 0.05). All fractures healed well in both groups without complications. There was no significant difference between these two groups in terms of range of motion, grasp, bone healing period, and functional outcomes. Conclusion  Despite the well-known fact that, smoking has negative implications in the fracture healing process, we found group of patients (smoking and nonsmoking) with distal radius fractures treated by volar locking plates healed well with good radiological union and excellent functional outcome There is no significant influence of smoking in distal radius fracture fixation.

Arthroscopic resection of the distal clavicle in osteoarthritis of the acromioclavicular joint

Background:Symptomatic acromioclavicular joint (ACJ) lesions are a common cause of shoulder complaints that can be treated successfully with both conservative and surgical methods. There are several operative techniques, including both open and arthroscopic surgery, for excising the distal end of the clavicle. Here, we present a new modified arthroscopic technique for painful osteoarthritis of the ACJ and evaluate its clinical outcomes. Our hypothesis was that 4- to 7-mm resection of the distal clavicle in an en bloc fashion would have several advantages, including no bony remnants, maintenance of stability of the ACJ, and reduced prevalence of heterotopic ossification, in addition to elimination of the pathologic portion of the distal clavicle.Results:The overall UCLA score was 13.7 preoperatively, which improved to 33.4 postoperatively. All subscores were improved significantly (P < 0.001). There were no specific complications at the latest followup.Conclusion:It is critical in this procedure to resect the distal clavicle evenly from superior to inferior in an en bloc fashion without any small bony remnants and to preserve the capsule and acromioclavicular ligament superoposteriorly. This arthroscopic procedure is a reliable and reproducible technique for painful osteoarthritis of the ACJ lesions in active patients engaged in overhead throwing sports and heavy labor.

病损内处置与整块切除治疗邻膝关节骨巨细胞瘤的比较观察

目的：研究病理Ⅰ、Ⅱ级,Ｘ线表现为ＣａｍｐａｎａｃｃｉⅡ、Ⅲ期的邻膝关节骨巨细胞瘤的治疗。方法：从１９７８～１９９３年住院治疗的骨巨细胞瘤１０３例中,选择肿瘤部位、Ｘ线分期、病理分级及随访时间相仿的病损内处置（刮除、液氮冷冻并自体或异体植骨、或骨水泥填充）患者４１例（３例有病理性骨折）;整块切除后用异体半关节移植３０例（２例有病理性骨折）进行回顾性分析。结果：显示两组间局部复发率无统计学差异,而病损内处置的术后并发症,再手术率及肢体远期功能评分均明显好于整块切除组。结论：有效的病损内处置仍应作为此类邻膝关节骨巨细胞瘤的首选治疗方法,即使诊断时伴有病理性骨折者亦然。     

Capitolunate Arthrodesis for Treatment of Scaphoid Nonunion Advanced Collapse (SNAC) Wrist Arthritis

The aim of the study was to evaluate results of capitolunate arthrodesis for the treatment of post traumatic degenerative SNAC wrist disorders. A capitolunate arthrodesis was performed on 12 patients, three women and nine men, of 44 years in average (28–66 years). Ten patients were manual workers; dominant side was involved in seven cases with no history of previous operation. Fixation of the arthrodesis was performed with headless compression screws. Patients were reviewed at 37.4 months of average follow up (range; 12–47 months). Mayo score equal to 82.8 points. Radiolunate and capitolunate angles were decreased of 6 and 8° respectively at the final follow up radiograph compared to preoperative values. The Ten manual worker patients were able to return to their previous professional activities and the other two patients were retired but they resume their sports and recreational activities. With the advent of headless compression screws the capitolunate arthrodesis gained a higher union rate, short operative time and short rehabilitation period. In the present study the capitolunate arthrodesis allowed restoring a stable functional wrist in the 12 patients reviewed. It is a satisfactory therapeutic alternative to four corners fusion for SNAC wrist with osteoarthritis.     

Outcome Following Acute Primary Distal Ulna Resection for Comminuted Distal Ulna Fractures at the Time of Operative Fixation of Unstable Fractures of the Distal Radius

Optimal acute management of the highly comminuted distal ulna head/neck fracture sustained in conjunction with an unstable distal radius fracture requiring operative fixation is not well established. The purpose of the present study was to determine the clinical, radiographic, and functional outcomes following acute primary distal ulna resection for comminuted distal ulna fractures performed in conjunction with the operative fixation of unstable distal radius fractures. Between 2000 and 2007, 11 consecutive patients, mean age 62 years (range, 30–75) were treated for concomitant closed, comminuted, unstable fractures of the distal radius and ulna metaphysis. All 11 patients underwent distal ulna resection through a separate dorsal ulnar incision with ECU tenodesis following surgical fixation of the distal radius fracture. According to the Q modifier of the Comprehensive Classification of Fractures, there were six comminuted fractures of the ulnar neck (Q3) and five fractures of the head/neck (Q5). Operative fixation of the distal radius fracture included volar plate fixation in four patients and spanning external fixation with supplemental percutaneous Kirschner wires in seven patients. At a mean of 42 months (range, 18–61 months) postoperatively, clinical, radiographic, and wrist-specific functional outcome with the modified Gartland and Werley wrist score were evaluated. At latest follow-up, mean wrist range of motion measured 53° flexion (range, 35–60°), 52° extension (range, 30–60°), 81° pronation (range, 75–85°), and 77° supination (range, 70–85°). Mean grip strength measured 90% of the contralateral, uninjured extremity (range, 50–133%). No patient had distal ulna instability. Final radiographic assessment demonstrated restoration of distal radius articular alignment. According to the system of Gartland and Werley as modified by Sarmiento, there were seven excellent and four good results. No patient has required a secondary surgical procedure. Acute primary distal ulna resection yields satisfactory clinical, radiographic, and functional results in appropriately selected patients and represents a reliable alternative to open reduction and internal fixation when anatomic restoration of the distal ulna/sigmoid notch cannot be achieved. Primary distal ulna resection with distal radius fracture fixation may help avoid secondary procedures related to distal ulna fixation or symptomatic post-traumatic distal radioulnar joint arthrosis.
