OBJECTIVE: To investigate the feasibility and effectiveness of absorbable anchor combined with Kirschner wire fixation in the reconstruction of extension function of old mallet finger. METHODS: Between January 2020 and January 2022, 23 cases of old mallet fingers were treated. There were 17 males and 6 females with an average age of 42 years (range, 18-70 years). The cause of injury included sports impact injury in 12 cases, sprain in 9 cases, and previous cut injury in 2 cases. The affected finger included index finger in 4 cases, middle finger in 5 cases, ring finger in 9 cases, and little finger in 5 cases. There were 18 patients of tendinous mallet fingers (Doyle type Ⅰ), 5 patients were only small bone fragments avulsion (Wehbe type ⅠA). The time from injury to operation was 45-120 days, with an average of 67 days. The patients were treated with Kirschner wire to fix the distal interphalangeal joint in a mild back extension position after joint release. The insertion of extensor tendon was reconstructed and fixed with absorbable anchors. After 6 weeks, the Kirschner wire was removed, and the patients started joint flexion and extension training. RESULTS: The postoperative follow-up ranged from 4 to 24 months (mean, 9 months). The wounds healed by first intention without complications such as skin necrosis, wound infection, and nail deformity. The distal interphalangeal joint was not stiff, the joint space was good, and there was no complication such as pain and osteoarthritis. At last follow-up, according to Crawford function evaluation standard, 12 cases were excellent, 9 cases were good, 2 cases were fair, and the good and excellent rate was 91.3%. CONCLUSION Absorbable anchor combined with Kirschner wire fixation can be used to reconstruct the extension function of old mallet finger, which has the advantages of simple operation and less 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.

OBJECTIVE: To explore a surgical method for the reconstruction of volar soft tissue defect and sensory and vascular repair in middle and far phalangeal digits. METHODS: From January 2016 to January 2020, a total of 14 patients , 9 males and 5 females, ages ranging from 22 to 69 years old, and with volar soft tissue defects in the middle and distal digits 2 to 4, underwent surgical reconstruction using the V-Y shaped flap with digital artery and nerve at the metacarpophalangeal joint. The defect area was (2.0~2.5) cm×(1.5 ~2.0) cm. The procedure involved the harvest of a V-Y shaped flap with the digital artery and nerve from the metacarpophalangeal joint. Flap design, dissection of blood vessels and nerves, and anastomosis with the digital artery and nerve were performed according to a standardized protocol., Functional exercise of affected finger was initiated 3 weeks postoperatively. Subsequent assessments were conducted to evaluate finger pulp sensation, shape and other relevant parameters. According to the upper extremity functional evaluation standard set up by Hand Surgery Branch of Chinese Medical Association, the surgical outcomes were evaluated. RESULTS: All 14 cases demonstrated successful tissue transplantation, , with immediate recovery of sensation observed in 10 cases with distal finger pulp defects. Four patients with middle phalangeal defects experienced gradual sensory recovery within 2 to 3 months postoperatively. Thirteen patients were followed up for a mean duration of (8.8 ± 4.49) months, during which satisfactory outcomes were observed. The average two-point resolution of the finger pulp was 4-6mm, and sensory function evaluation yielded a score of S3 or above. Patients exhibited realistic finger shape, normal skin color and temperature, good wear resistance, and cold resistance. Furthermore, finger joint function was essentially normal. CONCLUSION The V-Y shaped flap with digital artery and nerve at the metacarpophalangeal joint offers a suitable solution for repairing the defect of the middle or distal phalangeal finger. This technique is characterized by its simplicity, low risk, and favorable outcomes, including restored finger shape, blood supply and sensation. Moreover, high patient satisfaction was achieved.

OBJECTIVE: To investigate the effectiveness of dorsal perforator flap of cross-finger proper digital artery in the treatment of finger soft tissue defect caused by high-pressure injection injury. METHODS: Between July 2011 and June 2020, 14 cases of finger soft tissue defect caused by high-pressure injection injury were repaired with dorsal perforator flap of cross-finger proper digital artery. All patients were male, with a mean age of 36 years (range, 22-56 years). The defects were located on the index finger in 8 cases, middle finger in 4 cases, and ring finger in 2 cases. The causes of injury include 8 cases of emulsion paint injection, 4 cases of oil paint injection, and 2 cases of cement injection. The time from injury to debridement was 2-8 hours, with a mean time of 4.5 hours. The soft tissue defects sized from 4.0 cm×1.2 cm to 6.0 cm×2.0 cm. The flaps sized from 4.5 cm×1.5 cm to 6.5 cm×2.5 cm. The donor site of the flap was repaired with skin graft. The pedicle was cut off at 3 weeks after operation, and followed by functional exercise. RESULTS: All flaps and skin grafts at donor sites survived, and the wounds healed by first intention. Twelve patients were followed-up 16-38 months (mean, 22.6 months). The texture and appearance of all flaps were satisfactory. The color and texture of the flaps were similar to those of the surrounding tissues. The two-point discrimination of the flap was 10-12 mm, with a mean of 11.5 mm. There were different degrees of cold intolerance at the end of the affected fingers. At last follow-up, the finger function was evaluated according to the Upper Extremity Functional Evaluation Standard set up by Hand Surgery Branch of Chinese Medical Association, 3 cases were excellent, 8 cases were good, and 1 case was poor. CONCLUSION The dorsal perforator flap of cross-finger proper digital artery can effectively repair finger soft tissue defect caused by high-pressure injection injury. The operation was simple, and the appearance and function of the finger recover well.

BACKGROUND: Camptodactyly refers to permanent flexion contracture at the proximal interphalangeal joint. Most cases are limited to fifth-finger involvement. Although common, the treatment of camptodactyly is controversial. Many published studies have emphasized conservative treatment, while others have described surgical procedures. The problem with this deformity is that it presents in several forms, which means that there is no single model for effective treatment. The aim of this paper is to present the difficulties encountered with this condition and the management thereof on an individual basis. METHODS: This is a case series of 14 patients (nine males, five females) who underwent surgical treatment. The results were classified using the method from Mayo Clinic as excellent, good, fair, and poor. RESULTS: Fourteen patients with 15 fingers underwent surgery, and the results achieved were as follows: excellent, 0; good, 1; fair, 6; poor, 8. The treatment of camptodactyly still remains controversial, and hence proper planning individualized to each patient is needed to achieve the maximal improvement with realistic goals. CONCLUSIONS: Although we performed individualised surgery, our careful follow-up was not able to identify any method as superior over another with respect to gain in extension and loss of flexion. We therefore propose that the extensor mechanism should not be disturbed during surgery to treat camptodactyly cases.

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.

OBJECTIVETo investigate the therapeutic effects of repair of skin and soft tissue defects at distal end of finger with serrated flap with digital proper artery and nerve pedicle combined with bilaterally pedicled V-Y advancement flap of the injured finger.

METHODSThirteen patients with skin and soft tissue defects at distal end of 13 fingers were hospitalized from September 2013 to January 2015. After debridement, the wound area of finger ranged from 1.2 cm × 0.8 cm to 1.8 cm × 1.5 cm. Serrated flap with digital proper artery and nerve pedicle combined with bilaterally pedicled V-Y advancement flap of the injured finger were used to repair the defect. The flaps were interruptedly sutured. The areas of bilaterally pedicled V-Y advancement flap and serrated flap with digital proper artery and nerve pedicle ranged from 0.52 to 1.11 and 2.60 to 5.23 cm(2,) respectively.

RESULTSAll flaps of 13 patients survived completely. The patients were followed up for 6 to 24 months. The color and texture of the flaps were good. After reconstruction, the finger tips were in round in shape. The appearance of the fingers was consistent with that of the normal fingers, and joint motility was normal. No hook-nail deformity or knuckle dysfunction was found. Sensation of the flaps was estimated as S4, and the distance of two-point discrimination ranged from 2 to 3 mm. The recovery of the joint motion function of the fingers was excellent.

CONCLUSIONSSerrated flap with digital proper artery and nerve pedicle, combined with bilaterally pedicled V-Y advancement flap from the injured finger can repair the skin and soft tissue defects at distal end of finger with reliable blood supply and simple operative technic. It also could avoid the formation of deformity subsequent to a linear scar, and a satisfactory appearance with good function could be obtained.

Multicentric reticulohistiocytosis (MRH) is a rare systemic disease, which commonly manifests as muco-cutaneous papulonodules and inflammatory erosive polyarthropathy. In this research, we report the clinical manifestations and management of a rare case of MRH with destructive arthropathy of bilateral hip joints and arthritis mutilans presenting with characteristic deformities. Disabling hip arthropathy that occurs secondary to MRH can be successfully managed with bilateral total hip arthroplasty (THA). Osteopenia and acetabular bone defects must be anticipated during THA. This case is reported due to its rare occurrence and because little literature has been published regarding THA in such patients.

OBJECTIVETo explore the relative factors on the failure in digit replantation in order to take preventions to control the risk factors.

METHODSFrom January 2013 to December 2013, 236 consecutive patients (311 fingers) underwent digit replantation were collected to analyze retrospectively, involving 183 males and 53 females with an average age of 34.5 years old ranging from 2 to 62 years old (6 cases under 6 years old and 230 cases elder than 6 years old). There were 51 thumbs, 87 index fingers, 78 middle fingers, 63 ring fings and 32 little thumbs. Forty cases(forty fings) who were failured as the observation group, the others as the control group. The factors of age, gender, finger, cause of injury, smoking history, ischemia duration, plane of division, condition of venous drainage and condition of arterial repair we assessed.

RESULTSAll 236 cases with 311 fingers were replanted, 40 fingers were failured after operation. The relative factors on the failure in digit replantation included smoking history, cause of injury, plane of division, condition of venous drainage and condition of arterial repair (P< 0.05). There were no significant correlation between the failure and age, gender, finger and ischemia duration (P>0.05).

CONCLUSIONSmoking history, causes of injury, plane of division, condition of venous drainage and condition of arterial repair are risks of failure in digit replantation. Before choosing the type of operation, it should be think about the patient's general conditions, injury status, grasp firmly the operative indications and actively carry out surgical treatment.
