INTRODUCTION

In recent years the age of world's population has risen and with it there has been a significant increase in the frequency of hip fractures in the elderly. These fractures are known to increase morbidity and mortality. However, little is known about the frequency and characteristics of patients who sustain a second hip fracture. We examined the incidence and the underlying associated medical disorders of patients with a second fracture in the other hip.

Introduction: Meniscal tears are common in young athletes, usually result from a twisting injury during sport and may occur in the anterior or posterior horns. Injured menisci may be treated arthroscopically by excision of the torn fragments. However, in patients with peripheral meniscal detachment, located at the “vascular zone”, operative repair is feasible and usually successful. Meniscal repair may be done by open direct suture of peripheral tears or by arthroscopic techniques as “Outside-In”, “Inside-Out” or “All-Inside”. We present our experience with arthroscopic suture of completely detached menisci.

Patients & Methods: This study consisted of 33 male patients (14-48Y; mean 25Y; Follow-up: 2-6Y; mean 3.5Y). Inside-Out technique was used in 31 patients and Outside-In technique in two patients. 16/33 patients had detachment of the peripheral half of the meniscus (14-medial; 2-lateral); 13/33 patients had peripheral detachment of almost two thirds of meniscus (10-medial; 3-lateral) and 4/33 patients had detachment of one third of the meniscus (3-lateral; 1-medial injuries; all combined with fractures of the tibial plateau). 15 patients with medial meniscus detachment had complete (5 Pts) or partial (10 Pts) tear of ACL. Two other patients with medial meniscus detachment had associated small radial tears of the affected meniscus. Two of the patients with complete ACL tear had later been operated upon for reconstruction of ACL. Results were assessed by the Knee Society Knee score and by Lysholm Scoring Scale.

Results: 25/33 patients (76%) had good and excellent results. Four of them developed re-tear and detachment of medial meniscus during other later additional sport injuries, usually between 1–2 years following initial treatment. Four other patients had a “second” arthroscopic look 1–2 years later following another sport twisting injury and in all of them a stable peripheral attachment of the sutured menisci was observed. Results were better in patients who had ACL reconstruction a few months following meniscal repair. 5 patients had fair results (15%) and 3 patients had poor results (9%).

Conclusions: Based on this study it is suggested that meniscal suturing for peripheral tears is a satisfactory procedure. Meniscal tears suitable for repairs are those within the vascular zones (the outer third of the menis-cus), unstable on probing, are longer than 7mm and without major surgical damaging. Tears of posterior segments are the most difficult to suture and often require open arthrotomy. ACL reconstruction combined with meniscal repair appears to increase the healing rate of the meniscus. There are also adjuvant techniques for meniscal repair such as: fibrin clot or laser (both are weaker than suture alone) and adhesives. However, there is still not enough data.

Purpose: We report our experience with ankle arthrodesis using Ilizarov External fixator in 18 patients with extensive damage of the ankle joint, mainly with post traumatic osteoarthrosis, during the last 7 years.

Materials and Methods: The mean age of the patients was 36 years (range 21–54 years). 14 Pts had posttraumatic arthrosis following complicated intraarticular fractures, 3 Pts had extensive osteochondritis dissecance and 1 had failure of union after RAF arthrodesis of ankle. No cases of osteomyelitis of ankle were included in this seria. All procedures were done with open arthrotomy, 6 through lateral approach and 12 through anterior approach. Bone grafting was used in 3 cases due to extensive damage of talar bone. Temporary fixation by Steinman pin was done in all cases after open alignment of ankle joint, and then Ilizarov external fixator was applied, followed by removal of the temporary fixation. Full weight bearing was allowed from the 3^rd or 4th postoperative day. Time in fixator ranged from 6 to 14 weeks (average 9,5 weeks).

Results: Solid arthrodesis was achieved in all cases. 15 patients were free of pain, 2 patients continued to complain of pain due to degenerative changes in subtalar joint which presented before surgery. 1 patient developed RSD and was treated successfully by analgesics and physiotherapy. 5 cases of superficial pin tract infection were observed and treated with antibiotics. There were no cases of deep wound infection in this series.

Conclusions: This method has been proven useful for primary arthrodesis of ankle joint, mainly for complicated cases after multiple surgeries, or in patients with advanced post-taumatic changes.

We report an unusual complication of late dislocation of a total hip replacement. The femoral stem had completely migrated from the shaft. The insertion of a new long-stem prosthesis was successful.
