The flexor tendon injuries of the finger are very difficult to treat satisfactorily. Early treatment is desirable, but not always posaible. In addition, joint stiffness and limitation in gliding of the tendon caused by adhesion, make the problem more complex. From 1978 until 1988, 13 patients (14 eases) underwent operations for free tendon graft, and 10 patients (13 eases) for staged tendon graft at the Department of Orthopaedic Surgery, National Medieal Center. They have been followed up for clinical study, and the result was summarized as follows:1. Old flexor tendon injuries were common in the teen and twenties, especially in male. 2. They occurred in the index (10 Cases, 37.0%) and middle (8 cases, 29.6%) fingers most commony, especially zone II (62.9%). 3. The result was evalusted according to the method designed by Strickland and Glovac. In 19 out of 27 cases, satisfactory result (excellent and good) was yielded. 4. In cause, deep laceration by sharp object was better in the result than crushing injury. 5. The interval between the injury and the operation ranged from 1 month through 11 years, averaging 16 months, and is supposed to have little relation to the result. 6. The preoperative state is supposed to have much relation to postoperative result, judging from 100% of satisfactory result in Grade I compared with 40% in Grade V according to Boyes preoperative classification. 7. Little difference is seen in the result between free tendon graft and staged tendon graft. And 5 cases complicated by adhesion, rupture of grafted tendon and wound infection yielded poor result.

Tennis elbow is common, and offen disabling problem even in daily living;conservative treatments commonly make satisfactory results, but recurrence is frequent and discouraging. So, surgical treatments are considered in certain cases. The authors report the retrospective analysis of 15 patients treated by nirschl and pettrone procedure. Patients were evaluated with Nirschl and Pettrone assessment method at an average 10.3 months(range, 5 to 32 months0 after surgery. thirteen of 15(87%) patients had more than fair postoperative rating. Two patients had postoperative complications;one with infection and the other with transient mild limitation of elbow motion. No postoperative deterioration of the clinical state was seen. And biopsy specimens of all case showed degenerative changes. Resection of the degenerated site of tendon origin of the humeral epcondyle(The Nirschl and Pettrone procedure) yield satisfactory results in properly selected patients.

The first metacarpal base fracture is classified as extra-articular fracture, intra-articular fracture and epiphyseal injury. Intra-articular fracture was firstly described in 1882 by Bennett and Rolando described about Y shape comminuted fracture in the first metacarpal base in 1910. In 1938, Robert wrote about oblique fracture injured by first metacarpal base fracture. First metacarpal base fracture can be adjusted easily by C/R, but it is difficult to maintain the good axis. In case of fail of reduction, malunion, joint stiffness and traumatic arthritis can be shown as complications and finally some problems in grasping and pinching are resulted. Therefore, firstly the most accurate reduction, secondarily effective method to maintain the condition and thirdly the protection of limitation of motion are goal of treatment. Authors reviewed 17 cases treated by 0/R & C/R for the past 5 years from 1975 to 1980 at National Medical Center, especially reviewed the cases of which observation more than 1 year was possible. The results were as followings: 1. The incidence of first metacarpal base fracture was 1.0% of all fractures & dislocations. 2. Out of 17 cases, there were 14 male and right side 9 cases and left side was 8 cases. 3. The most common case of fracture was injury at work and traffic accident, sports injury, slipping down and falling down. 4. The method of treatment were C/R & percutaneous pinning in 10 cases and 0/R & K-wire fixation were 7 cases. 5. The result of treatment showed 8 excellent, 1 good, 1 fair, out of 10 cases of C/R and percutaneous pinning. In 0/R and K-wire fixation, 4 excellent, 2 good, and 1 fair showed out of 7 cases. 6. Soft tissue infection was appeared from 1 case of open fracture which accompanied second metacarpal fracture as complication and it caused adduction contracture in first web space.

Fractures of the phalanges of the hand are very common. Many are minor and likely to have a good result. However many other phalangeal fractures cause significant and prolonged disability. Non-union of the tubular bones of the hand are uncommon occurrence, but are often associated with functional deficits. The authors have reviewed 7 cases of non-union of the phalanges which were treated in the department of orthopaedic surgery, National Medical Center from 1978 to 1985. The results were summarized as follows: 1. The non-union of phalangeal bone was defined by clinical symptoms and signs and roentgenological examination. 2. The incidence of non-union of phalangeal bone fractures was 0.9% (7/771 cases.) 3. of 7 patients, there were 6 in male and 1 in female. 4. Non-union occurred more commonly in the second decade and the group between 10 and 30 years of age. 5. Seven cases, all were the right handed, but injury was developed in the left hands except two cases. 6. The causes of non-union were thought as open wound (7 cases), type of fracture (simple or comminution:3 cases), inadequate immobilization (4 cases) and overtraction (1 case). 7. of 7 cases, 4 cases were treated with bone peg graft and K-wire fixation and 2 cases with excision of distal fragment. 8. The clinical union was 9 weeks in average.

T The Flexor tendon injury caused by trauma of hand and forearm is commonly reported and earlier treatment for trauma is recommendable. But in many cases, earlier treatment is often not possible due to degree of injured tissues and infection. Specially in cases of severe trauma and damage of tendon sheath and pulley, the solution of limitation of motion is still remained as a difficult problem up to present due to scar tissue adhesion to surrounding tissues even after the primary treatment. The Department of orthopaedic surgery of National Medical Center during four years from 1981 to 1985 have treated 22 patients (27 fingers) of old flexor tendon injuries with tendon reconstruction and followed up more than for 6 months for clinieal study arrd the results ase as follows: 1. The old flexor tendon injuries are composed of 18 patients of the first decade and the second decade, especially in male. 2. The main causes of injury were deep lacerations by sharp objects (12 patients, 55.6%) and crushing injuries (9 patients, 40.8%). 3. Tendon injuries were mostly occurred in the index and ring finger. The incidence rate was equal between the 2 fingers, 25.7% representatively. Most of the injuries (21 cases, 77.8%) occurred in the zone II (Kleinert classification). 4. According to Boyes' classification, Grade 2 was 16 patients (19 cases): Grade 4, 3 patients (4 cases): Grade 3, 2 patients (3 cases): and Grade 5, 1 patient. 5. The operation method in zone II was free tendon graft in 10 cases and staged tendon graft in 7 cases. 6. The timing of operation depends on whether the open wounds were completely healed or not as well as subsidence of swelling. In case of swelling. In case of stiff fingers normal range of motions should be restored by vigorous exercise before operation. 7. According to the assessment based on strickland and Glovac, 20 cases out of 22 cases (13 cases of free tendon graft and 9 cases of staged tendon graft were satisfactory result.

One of the commonest and most serious problems of the injured hand is flexion contractures of the fingers. Such deformities not only functionally impair the digit, but also reduce or restrict the functional capability of the entire hand. We reviewed 150 digits of 73 patients with flexion contractures of the fingers which had been treated at National Medical Center from Jan. 1976 to Dec. 1985. The results were as follows: 1. The duration of flexion contractures which were scattered from 4 months to 17 years and average duration of contracture was 20.6 months. 2. The methods of treatment were Z-plasty, adhesiolysis, capsulotomy, excision of both collateral ligaments, stripping of extensor mechanism and volar plate and release of flexor tendon sheath according to injury mechanism and duration of contracture. 3. The postoperative results showed up 32 (21.3%) excellent, 78 (52%) good, 24 (16%) fair and 16 (10.7%) poor. 4. The postoperative results of burned injury which showed up-8 excellent, 11 good out of 20 cases they are supposed to have satisfactory results. 5. Crushing injury which had intraarticular fracture or comminution show up unsatisfactory results. 6. It seems obvious that the early active motion of interphalangeal joint is important to improve joint function. 7. The arc of motion was retained in a more functional position postoperatively than preoperatively.

It is well known that many cases of renal cell carcinoma accompanies gross or microscopic hematuria. It implies that much of renal cell carcinoma may also have pelvic or medullary invasion. But unlike other well known prognostic factors such as renal vessel or regional invasion, the prognostic significance of pelvic or medullary invasion in renal cell carcinoma has not been known well. We reviewed retrospectively 73 patients treated with radical nephrectomy in whom 18 patients has pathologically confirmed pelvic or medullary invasion. The mean follow-up duration was about 23 months. The average size of tumor in non-pelvic invasive group (NPIG) was 6.6 cm and in pelvic invasive group (PIG) it was 5.4 cm. In NPIG, 91% (67 patients) of tumor was Grade II and III and in PIG 100% of tumor was Grade II and III. 89% of NPIG tumor was stage pT3aN0M0 or below. And 88% of PIG was pT3aN0M0 or below. At 12 NPIG patients (16%) tumor has recurred and its mean duration was about 6.6 months. In PIG, 5 patients had recurrent tumor (27%) and its duration was about 7.6 months. Nine patients (12.3%) died due to renal cell carcinoma in NPIG. In PIG 3 patients (16%) died of renal cell carcinoma. The study revealed that there is no significant difference between pelvic or medullary invasive and non-pelvic invasive renal cell carcinoma in tumor grade and stage. But in pelvic invasive renal cell carcinoma, relatively more tumor recurrence had occurred (p>0.05) and also relatively more patients died due to tumor. We think that for more proper clarification of prognostic significance of pelvic or medullary invasion in renal cell carcinoma, more long term follow-up and stage by stage study will be needed.
