A 72-year-old woman had her bladder injured accidentally during repair of a severe hernia of the abdominal wall. Primary closure was impossible because of previous heavy irradiation. We therefore did an ileocystoplasty to cover the defect. Her postoperative course was uneventful, and she could void spontaneously at seven months postoperatively.

We report three cases of malunion after fractures of the proximal phalangeal neck in children. A 12-year-old boy and a 7-year-old girl had malunited fractures with dorsal and ulnar deviation of their fingers. Several years later remodeling had been achieved well for dorsal deviation but little for the ulnar deviation in each case. A 10-year-old boy had a similar malunited fracture with dorsal and ulnar deviation of his finger. The proximal bony spike, which protruded to the volar side, collided with the middle phalanx during flexion of the proximal interphalangeal (PIP) joint, so we shaved it. One year after operation, flexion of the PIP joint had improved. In cases of these malunited fractures in children, remodeling is considered possible for dorsal deviation but difficult for ulnar deviation. Surgical shaving of the protruding bone should be considered.

The operative treatment of mallet fractures of more than one third of the articular surface is controversial. The purpose of this study was to evaluate the complications and functional outcome of extension block pinning technique. Thirty-six consecutive patients with mallet fractures that involved more than one third of the joint surface were treated by extension block pinning a median of 3 days after injury (range 0-35, mean 7). Clinical outcome was graded according to Crawford's criteria. At a median follow-up of 16.5 months (range 2.5-52, mean 20) 23 patients had an excellent or good result, 11 patients had a fair, and 2 patients a poor, clinical outcome according to Crawford's criteria. None of the patients complained of pain. The median extension loss was 0 degrees (range 0-20, mean 4) and the median flexion was 70 degrees (range 30-95, mean 68). Eight patients had operative or direct postoperative complications including superficial infection (n = 6), loss of Kirschner wire (K-wire) fixation (n = 1), and K-wire mal position (n = 1). The extension block pinning technique is a minimally invasive method of treating mallet fractures with low morbidity and a good functional outcome.

Some patients develop an intrapelvic infection and fistula caused by the presence of intrapelvic dead space after the resection of rectal cancer, and the treatment is sometimes quite difficult. We have developed a new surgical technique for the treatment and prevention of such fistulas that uses a fasciocutaneous flap from the medial thigh. A V-shaped fasciocutaneous flap with a pedicle on the anterior side of the thigh is designed on the medial thigh and gluteal region. After raising the fasciocutaneous flap that contains the long saphenous vein, the gluteal section including a thick layer of fatty tissue is de-epithelialised, and the flap is rotated and advanced towards the dead space to fill it. Four patients were operated on using our technique. One was a secondary reconstruction: the patient had developed a small fistula after reconstructive surgery, but it healed with conservative treatment. As a result, all four patients achieved satisfactory outcomes. The advantages of our technique include: no change in the position of the body is required for reconstruction; operations are simple; sufficient volume of tissue is obtained from the thick fatty tissues of the gluteal region; and the fasciocutaneous flap contains the long saphenous vein and has good venous circulation. We consider this technique useful for the reconstruction of intrapelvic dead space.

The results after primary repair of zone 2 flexor tendon injuries were evaluated in 263 fingers in 192 patients using two different early-controlled mobilisation programmes. There were 126 men and 66 women (age range 18 to 57 years) divided into two groups. Ninety-eight patients with 137 fingers were treated by early active mobilisation with dynamic splinting method according to a modified Kleinert regimen (Washington regimen), and 94 patients with 126 fingers were managed with a controlled passive movement regimen postoperatively. During this evaluation patients were evaluated for total active movement (TAM), grip strength, and disabilities of arm, shoulder, and hand (DASH) questionnaire. All patients were also reviewed 12 weeks after operation and the results assessed by the Buck-Gramcko-II system. Total active movement was "excellent" in the Washington regimen group (n=119, 87%), while excellent results of the fingers were achieved in the controlled passive movement group (n=94, 75%). The mean grip strength of the injured hand was 89% that of the non-injured side in the Washington regimen group, compared with 81% in the controlled passive movement group. The mean DASH score was 30 and 42 in the two groups, respectively. We think that controlled active mobilisation with dynamic splinting improves the outcome in the upper extremity, including range of movement, grip strength, and functional state of the hand in repairs of the flexor tendons.

Our aim was to explore the anatomical features of the cutaneous perforators from the ulnar palmar digital artery of the little finger and to establish the anatomical basis of the ulnar palmar digital artery perforator flap for reconstruction of the ulnar aspect of the palm and fingers. We found that at least one perforator is present between the metacarpophalangeal (MCP) joint and 9 mm proximal to the MCP joint. This finding establishes the anatomical basis of the distal base ulnar palmar digital artery perforator flap for reconstruction of the ulnar aspect of the palm and fingers.

We aimed to evaluate a new technique for intraoral expansion of soft tissue with a self-inflatable expander in rabbits. We placed a self-inflatable soft tissue expander bilaterally in eight rabbits under the periosteum of the mandible through an extraoral approach. The expander was left to self-inflate for two weeks, after which the animals were killed and specimens collected for histological examination. The self-inflatable soft tissue expanders expanded the periosteum. There were no dehiscences or infections. Histological observations showed no signs of any inflammatory reaction and there was no evidence of bony resorption. New bone had formed at the edges of the expanded periosteum. In the control area no new bone had formed. The osmotic soft tissue expander model for intraoral soft tissue and periosteal expansion suggests a promising way of creating a surplus of soft tissue that can be used to cover bone grafts.

We investigated the use of direct lengthening of the distal stump of a peripheral nerve to compare the results of nerve regeneration using the direct lengthening method with simple end-to-end suture and autografting in rats. A segment 10 mm long was resected from the rat sciatic nerve (n=18 in each group). The distal nerve stump was fixed to a ring and pulled at a rate of 1 mm/day for 20 days using an original external nerve distraction device. The results showed that the degree of nerve regeneration in the lengthened group was superior to that of the grafted group electrophysiologically and histologically, but there were no significant differences between the lengthened and end-to-end suture groups. We conclude that direct lengthening of the distal stump of a peripheral nerve can promote nerve regeneration similar to that observed in a Wallerian degenerated nerve. We think that this technique may be used for the treatment of peripheral nerve injuries.

The aetiology of the "tennis" elbow is still disputed and treated by numerous different operations. We report 24 patients with treatment-resistant, previously denervated epicondylitis. The revision consisted of complete decompression of the radial nerve from the lateral intermuscular septum to beyond the arcade of Frohse in 24 patients using an anterolateral access. There was a mean period of 31 (10) months between the onset of the condition and the revision. Compared with the preoperative findings, there were improvements in 19 of the 24 patients, with four patients remaining unchanged, and one patient deteriorating. If the condition has been resistant to treatment for some time, complete decompression of the radial nerve is an effective option with few complications compared with further operation on the epicondyle.
