21 hands and fingers of 13 patients (male 11, ages of 20-41) of which 11 cases of separated fingers or hands treated by microsurgery and antibiotics, anti-inflammatory drugs. The results have shown that the microsurgery successfully reimplanted the separated fingers in the segment 1 or 2. The factors played an important role for success of microsurgery was vascular anastomosis. In addition to, the preservation of separated limbs, removal of damage tissue also played an important role

The minimally invasive release treatment of TCM Small Needle-Knife for the stenosing tenosynovitis of flexor digtorum-"trigger finger" has a more satisfied efficacy. In recent years, many clinicians use self-made small sharp scalpels, iris knives, small sickles, push shear knives, and other improved alternatives to instead of the traditional small needle-knives. Changing the original small needle-knife vertical stabbed cutting method, take a mini-incision, along the traveling direction of flexor tendon make a vertical hook cut, pick cut, straight push cut and any other cuts, completely cut the stenosis of the tendon sheath pulley, to achieve the release therapeutic purposes. The experience of most scholars is: Detailed and thorough understanding refers to the anatomical level of the flexor tendon and surrounding tissue, the structural relationship; Strictly adhere to the indications of minimally invasive release therapy; Proficiency in a dedicated minimally invasive release needle-knives, scalpels, and standardized methods of operation; Accurate positioning before surgery, in surgery traveling direction along flexor tendon, continuous incision to release the middle along the tendon. It can achieve the same or even higher incision release efficacy than the traditional treatment, at the same time also avoids common adverse complications.

OBJECTIVE: To summarize the clinical characteristics, differential diagnosis, and treatment methods of finger flexion contracture caused by three kinds of forearm flexor diseases. METHODS: Between December 2008 and August 2021, 17 patients with finger flexion contracture were treated, including 8 males and 9 females, aged 5-42 years, with a median of 16 years. The disease duration ranged from 1.5 months to 30 years, with a median of 13 years. The etiology included 6 cases of Volkmann's contracture, all of which were flexion deformity of the 2nd to 5th fingers, accompanied by limitation of thumb dorsiflexion in 3 cases and limitation of wrist dorsiflexion in 3 cases; 3 cases of pseudo-Volkmann's contracture, including 2 cases of flexion deformity of middle, ring, and little fingers, and 1 case of flexion deformity of ring and little fingers; 8 cases of ulnar finger flexion contracture caused by forearm flexor disease or anatomical variations, all of which were flexion deformity of middle, ring, and little fingers. Operations such as slide of flexor and pronator teres origin, excision of abnormal fibrous cord and bony prominence, and release of entrapped muscle (tendon) were performed. Hand function was evaluated according to WANG Haihua's hand function rating standard or modified Buck-Gramcko classification standard, and muscle strength was evaluated according to British Medical Research Council (MRC) muscle strength rating standard. RESULTS: All patients were followed up 1-10 years (median, 1.5 years). At last follow-up, 8 patients with contracture caused by forearm flexor disease or anatomical variations and 3 patients with pseudo-Volkmann's contracture achieved excellent hand function, with muscle strength of grade M5 in 6 cases and grade M4 in 5 cases. One patient with mild Volkmann's contracture and 3 patients with moderate Volkmann's contracture without severe nerve damage had excellent hand function in 2 cases and good in 2 cases, with muscle strength of grade M5 in 1 case and grade M4 in 3 cases. Two patients with moderate or severe Volkmann's contracture had poor hand function, with 1 case of muscle strength of grade M3 and 1 case of grade M2, which improved when compared with those before operation. The overall excellent and good rate of hand function and the proportion of patients with muscle strength of grade M4 and above were 88.2% (15/17), respectively. CONCLUSION The finger flexion contracture caused by different etiology can be differentiated by analyzing the history, physical examination, radiographs, and intraoperative findings. After different surgical treatments, such as resection of contracture band, release of compressed muscle (tendon), and downward movement of flexor origin, most patients have a good outcome.

OBJECTIVETo evaluate a new fasciocutaneous island flap for the repair of volar skin defects of the same finger.

METHODSA fasciocutaneous island flap, 0.5 cm distal to the volar skin defect, was formed on the dorsal side of the same finger. The proximal fascial pedicle was dissected long enough so that the flap could be transposed to the volar wound freely. One dorsal vein was kept undisturbed to safeguard the venous drainage of the distal part of the finger. When the side of the flap was so big that bilateral dorsal veins were included within the flap, the non-pedicle side of the flap was elevated first superior to the fascia until the dorsal vein was excluded from the flap, and the rest of the flap was dissected deep to the fascia. The donor side of the flap was covered with split skin graft.

RESULTSSix cases were treated. All flaps survived well.

CONCLUSIONThe dorsal fasciocutaneous island flap of the finger can be used safely for the repair of volar skin defect of the same finger.

OBJECTIVETo introduce an operation for fingertip reconstruction.

METHODSThe vascularity of the reverse dorsal island flap is augmented by performing an arteriovenous anastomosis between the dorsal vein in the flap and a digital artery at the fingertip. The flap was used in ten patients for reconstruction of their fingertip defects.

RESULTSAll the ten flaps survived and the appearance was good.

CONCLUSIONThe method is easy except for the necessity of performing standard microvascular surgery. The flap is a good option for repairing fingertip defects.

Microvascular surgery in Korea started in 1970's. Doctor Poong Lim was one of several dedicated surgeons who made great efforts to develop this field in Korea. By performing inguinal free flap in 1978, he became the first man who applied microvascular surgical technique to the clinical field in Korea. In addition, he played an important role in the settlement of microvascular surgery in Korea, performing variety of free flaps such as omental free flap, dorsalis pedis free flap, and deltopectoral free flap in 1979. He also introduced microvascular surgery to the traumatic field by successfully performing multiple finger replantation and forearm replantation in 1979. Both his clinical and experimental works made it possible for microvascular surgery to become an important part of plastic surgery in Korea.

Trigger finger is a common disease particularly in the middle aged women. A very rare case in which an adult man had 10 trigger fingers was experienced. He was treated with local steroid injections in both thumbs, but trigger finger disease has been aggravated in every digit of both hands. We performed an early operative treatment. Three months after the operation, the patient could perform his work without discomfort in his hands and showed normal range of motion in all fingers.

In cases of severe segmental injury across the hand and wrist, but one or other fingers are still in peak condition, the fingers can be selected for replantation at the forearm bones to restore pinch function. Here we reported an unusual case with a severe crush-avulsion amputated injury to the right hand caused by a machine accident. We conducted hand reconstruction using heterotopic replantation of the amputated index and little fingers. During 19 months follow-up, the bone union healed well with satisfactory outcome. The interphalangeal and metacarpophalangeal joint of the fingers after the heterotopic replantation had a good holding activity. This is a worthwhile procedure and the patient is satisfied with the result. The major disadvantage of this method is the poor appearance of the reconstructed fingers.

A case of macrodactyly associated with neurofiborma of the median nerve, a congenital anomaly of the hand, affecting only one(left middle) finger is reported with a review of the literature. Macrodactyly which is also termed local gigantism, megalodactylism, megalodactylia, or macrodactylism in other literature, is a rare congenital malformation characterized by overgrowth of one or more fingers of hand. Macrodactyly associated with neurofibroma of the median nerve is especially rare. For this reason the following case is presented together with a review of the literature.

This paper describes a new technique in the repair of the hand defect with digital extensor tendon injury. The anterolateral thigh flap with the thick femoral fascia has been used in the reconstruction of the composite defect of the dorsal hand, especially the defect of tendon. This technique requires short period of treatment and hence causes less damage to the donor site but shows a better recovery of the hand function. A favorable curative effect has been obtained in this patient.
