Unicompartmental knee arthroplasty (UKA) has increasingly become an attractive alternative to total knee arthroplasty for early intervention. Clinical and biomechanical studies have shown that UKA offers advantages in early recovery, more natural function, and patient satisfaction. The literature has also shown that UKA exhibits a higher rate of revision than total knee arthroplasty, particular...

Between July 1986 and July 1994, we studied 125 total finger amputations due to crush and avulsion type injuries at the Izmir Hand and Microsurgery Hospital. Of the 125 fingers replanted, 88 were successful, for a general survival rate of 70.4%. In the period between 1986 and 1991, we performed end-to-end anastomoses and achieved a survival rate of 48.3% (Group I). Between 1991 and 1994, with t...

BACKGROUND We describe the case of a 16-year-old female patient with micrognathia, temporomandibular joint (TMJ) ankylosis, and obstructive sleep apnea, who was treated with mandibular distraction osteogenesis (DO) combined with sliding genioplasty, using skeletal anchorage. CASE PRESENTATION We first performed interpositional arthroplasty, in which an interposition of fascia temporalis and s...

background: the infection after total hip arthroplasty is one of the major and catastrophic complications and often cause multiple procedures, heavy cost and life threatens and disability for the patient. in this study, we report our experience about infected total hip arthroplasty. methods: in this study, among patients referred to kashani hospital in isfahan, iran from 2001 to 2007, 659 patie...

The term hallux rigidus is used to describe a condition characterized by pain and reduction of motion, especially in dorsiflexion, at the first metatarsophalangeal (1MTP) joint due to arthritis occurrence. The indication for surgery is pain combined with degenerative changes of the 1MTP joint. The surgical strategy has to be planned according to the degree of arthritis and is aimed to relieve p...

background:    previous studies suggest total hip arthroplasty may have some benefits compared to hemi-arthroplasty for displaced intracapsular femoral neck fractures in patients more than 60 years of age. the primary research question of our study was whether in-hospital adverse events, post-operative length of stay (los) and mortality in patients 60 year of age or older differed between total...

Varus and valgus joint laxity of the normal living knee in flexion was assessed using MRI. Twenty knees were flexed to 90 degrees and were imaged in neutral and under a varus-valgus stress in an open MRI system. The configuration of the tibiofemoral joint gap was studied in slices which crossed the epicondyles of the femur. When a varus stress was applied, the lateral joint gap opened by 6.7 +/...

PURPOSE OF THE STUDY The purpose of this study was to evaluate effectiveness of modified gap arthroplasty procedure and modified Myrhaug's preauricular incision for treating bony temporomandibular joint (TMJ) ankylosis. MATERIALS AND METHODS A total of 10 cases were included in the study with Sawhney's type III and IV TMJ ankylosis. Study consisted of 6 males and 4 females. Three cases were t...

We describe here various surgical options to obtain a correct rotational alignment of femoral component in total knee arthroplasty (TKA). The correct rotational alignment is the key point to obtain a rectangular balanced flexion gap as well to have a good patellar tracking. For that reason, rotation alignment largely affects postoperative kinematic results particularly during flexion.
