Elective free vascularized double transfer of toe joint from second toe to proximal interphalangeal joint of index finger: a case report.

Alternatives to the treatment of major injuries to the proximal interphalangeal (PIP) joint include fusion, implant arthroplasty, perichondrial grafting, single autogenous free vascularized transfer, and double autogenous free vascularized transfer. A patient presented a gunshot wound to the index finger with loss of skin and extensor tendon and PIP joint disruption. The finger was reconstructed with a composite free flap of skin and extensor tendon and PIP and distal interphalangeal joints of the second toe. A follow-up of 10 months is presented, which demonstrates PIP joint motion and finger function.

Vascularized toe joint transplantation.

The vascularized toe joint transfer is an alternative to arthrodesis. For optimal functional results, the patient must have normal-functioning muscle and associated tendons, effecting joint motion. Although vascularized toe joint transfer permits long-term preservation of joint architecture and cartilage, the goal of achieving normal range of motion for a reconstructed digit is still elusive. Reconstruction of the extensor mechanism can be worthwhile in selected patients because more useful motion can be achieved even if the result falls short of normal.

Vascularized toe joint transfer to the hand.

From 1984 to 1993, 36 vascularized toe joints were transferred in 33 patients. The present study group excludes 3 toe joint transfers to elbow and temporomandibular joints and 4 toe joint to hand transfers lost to follow-up. The final study group includes 29 vascularized toe joint transfers in 27 patients, 21 males and 6 females. All were performed for posttraumatic reconstruction, except one transfer for congenital deformity. Follow-up averaged 32.4 months. Mean range of motion was 34 degrees in toe metatarsophalangeal joint to hand metacarpophalangeal joint transfers, 32 degrees in toe proximal interphalangeal joint to hand metacarpophalangeal joint transfers, and 24 degrees in toe proximal interphalangeal joint to hand proximal interphalangeal joint transfers. Although vascularized toe joint transfer is an alternative to arthrodesis, in order to have a greater range of motion than average, the patient must have well-functioning muscle and associated tendons effecting joint motion. Good results were obtained in two immediate free vascularized toe joint transfers to complex injuries involving loss of the metacarpophalangeal joint. We encourage toe joint transfer in selected complex hand injuries.

Free vascularised toe joint transfer for reconstruction of the metacarpo-phalangeal joint.

Two single and two double free vascularised joint transfers from the foot to hand have been undertaken in four patients over a period of four years. All were to replace metacarpo-phalangeal joints in young patients in whom the use of prosthetic devices was considered unsuitable. All the transfers were successfully completed, but one failed late in the second post-operative week due to sepsis. The results of the remaining three transfers compare favourably with prosthetic arthroplasty and continue to improve. Donor site morbidity in the foot has been minimal and is reviewed.

[Experimental and clinical studies on free toe-joint transplantation to replace a finger joint by microvascular technic].

Major vascular pattern of the toe joints was investigated with template and transparent specimens in ten lower limbs of five Japanese monkeys and seven adult human amputated lower limbs. This led to the conclusion that the metatarsal artery should be used for toe MP joint grafts, while the unilateral proper digital artery is suitable for toe PIP joint grafts, together with concomitant or dorsal cutaneous vein. Twelve PIP and nine MP joints, a total of twenty-one experimentally grafted monkey toe joints with the above described vascular pedicles were radiologically and functionally in excellent condition after twelve months, whereas twenty-seven experimentally grafted monkey toe joints without vascular pedicles fell into cartilage degeneration after six months. Based on the results obtained from these experimental studies, nine human finger joints, consisting of two CM, four MP and three PIP joints, were replaced with either toe MP or PIP joints. One and half years on average after the grafting, the grafted toe joints were radiologically and functionally normal with growth of the open epiphysis.

Long-term results of free vascularized second toe joint transfers to finger proximal interphalangeal joints.

PURPOSE: To review the long-term clinical results of free vascularized second toe joint transfers for severely damaged finger proximal interphalangeal (PIP) joints. METHODS: Eleven joints in ten patients (1 woman, 9 men) were reviewed between 10 and 22 years after surgery. The average patient age at the time of the surgery was 32 years. Patients were evaluated at a mean follow-up time of 15 years; evaluation included range of motion of the transferred PIP joints and the remaining healthy second toe PIP joints, grip strength, finger and toe pain, finger function, gait disturbance, patient satisfaction, and x-ray changes. RESULTS: The mean active range of motion was 47 degrees that lacks 41 degrees extension and flexes to 88 degrees. The mean grip strength was more than 80% that of the nonaffected hand, and no finger pain or gait disturbances were reported. All patients had some extension lag and flexion contractures but most were satisfied with the clinical and functional results of surgery. In all joints, the joint spaces were preserved, although 1 patient had arthritis and 3 had osteophytes. CONCLUSIONS: It is important to prevent extension lag and flexion contracture to get better results from free vascularized second toe joint transfers. The transferred toe PIP joint is durable.

Detection of movements imposed on human hip, knee, ankle and toe joints.

1. The angular displacements necessary for 70% correct detection were determined in normal subjects at the hip, knee and ankle joints, and the interphalangeal joint of the big toe. Angular velocities between 0.1 and 50 deg s-1 were tested. The hip and knee joints were tested in slight flexion and the ankle and toe joints were tested in the mid-range of the normal excursion. The joints were carefully supported for testing and the muscles acting at the joints were relaxed. 2. When detection thresholds and velocities were assessed in terms of angular displacements and angular velocities, proprioceptive performances at the hip, knee and ankle joints were superior to that at the toe joint. 3. When detection levels and displacement velocities were expressed in terms of linear displacements and velocities at the tip of the extended toe for all four joints, instead of in angular terms, the ankle gave the best performance and the hip and knee the worst. 4. The detection level and velocity data were expressed also in terms of proportional changes in the fascicle lengths of muscles operating these joints. Analysis in these terms showed that performance was similar at the hip, knee and ankle joints, but that performance for the toe was much poorer than for the other joints. 5. These results for the hip, knee and ankle are similar to those previously measured for the elbow and distal interphlangeal joint of the finger, and are consistent with the theory that muscle fascicle length is the variable of significance to the central nervous system. However, the proprioceptive performance at the big toe is notably poorer than all other joints studied and analysed in terms of this variable.

Interobserver agreement in ultrasonography of the finger and toe joints in rheumatoid arthritis.

OBJECTIVE: To evaluate the interobserver agreement of ultrasonographic assessment of finger and toe joints in patients with rheumatoid arthritis (RA) by 2 investigators with different medical backgrounds. METHODS: Ultrasonography and clinical examination were performed on 150 small joints of 30 patients with active RA. A General Electric LOGIQ 500 ultrasound unit with a 7-13-MHz linear array transducer was used. In each patient, 5 preselected small joints (second and third metacarpophalangeal, second proximal interphalangeal, first and second metatarsophalangeal) were examined independently on the same day by 2 ultrasound investigators (an experienced musculoskeletal radiologist and a rheumatologist with limited ultrasound training). Joint effusion, synovial thickening, bone erosions, and power Doppler signal were evaluated in accordance with an introduced 4-grade semiquantitative scoring system, on which the investigators had reached consensus prior to the study. RESULTS: Exact agreement between the 2 observers was seen in 91% of the examinations with regard to bone erosions, in 86% with regard to synovitis, in 79% with regard to joint effusions, and in 87% with regard to power Doppler signal assessments. Corresponding intraclass correlation coefficient values were 0.78, 0.81, 0.61, and 0.72, respectively, while unweighted kappa values were 0.68, 0.63, 0.48, and 0.55, respectively. Ultrasonography showed signs of inflammation in 94 joints, while clinical assessment revealed tenderness and/or swelling in 64 joints. CONCLUSION: An experienced radiologist and a rheumatologist with limited ultrasound training achieved high interobserver agreement rates for the identification of synovitis and bone erosions, using an introduced semiquantitative scoring system for ultrasonography of finger and toe joints in RA. Signs of inflammation were more frequently detected with ultrasound than with clinical examination. Ultrasonography may improve the assessment of RA patients by radiologists and rheumatologists.

Articular fractures of the proximal interphalangeal joint with missing elements: repair with partial toe joint osteochondral autografts.

Five cases of traumatic destruction of a condyle of the proximal interphalangeal joint repaired with a free autogenous graft of a corresponding toe condyle are presented. Precise fitting is essential: 1 patient required a second graft when the initial undersized graft was absorbed. Four of the 5 cases regained laterally stable bicondylar joints and functional fingers. Range of motion varied inversely to the magnitude of the injury and the surgery. Active range of motion at the proximal interphalangeal joint was 80 degrees in 2 digits, 45 degrees in 1, and 10 degrees in 1 complex case; 1 case was considered a failure.

The smallest detectable difference and sensitivity to change of magnetic resonance imaging and radiographic scoring of structural joint damage in rheumatoid arthritis finger, wrist, and toe joints: a comparison of the OMERACT rheumatoid arthritis magnetic resonance imaging score applied to different joint combinations and the Sharp/van der Heijde radiographic score.

OBJECTIVE: To compare 2 magnetic resonance imaging (MRI) approaches and radiographic evaluation according to the Sharp/van der Heijde method with respect to sensitivity to change in joint destruction in patients with rheumatoid arthritis (RA). METHODS: Thirty-five RA patients and 9 healthy controls underwent MRI and radiography on 2 occasions 1 year apart. Conventional radiographs of the hands, wrists, and forefeet were evaluated according to the Sharp/van der Heijde method. MRIs of unilateral wrist and second through fifth metacarpophalangeal (MCP) joints ("few-joints approach") and of bilateral wrist and MCP joints plus unilateral metatarsophalangeal (MTP) joints ("many-joints approach") were assessed for bone erosions according to the scoring system recommended by the OMERACT (Outcome Measures in Rheumatology Clinical Trials) group. The smallest detectable differences (SDDs) of the radiography and MRI scores were computed based on reevaluation of one-third of the study population. RESULTS: Progressive joint destruction, i.e., an increase in score after the followup period, was observed more frequently with the MRI "many-joints approach" (30 subjects) and "few-joints approach" (25 subjects) than with the Sharp/van der Heijde radiographic method (9 subjects) (P < 0.001 by chi-square analysis). No significant difference between the MRI approaches was observed. When only subjects with a change greater than the SDD were considered, progression was revealed with the MRI "many-joints approach," the MRI "few-joints approach," and radiography in 15, 13, and 5 RA subjects, respectively. With both MRI approaches, significantly more subjects with progression were detected than were detected by radiography (P < 0.05). CONCLUSION: MRI, regardless of whether it covers unilateral wrist and MCP joints or bilateral wrist and MCP joints plus unilateral MTP joints, is significantly superior to radiography of the hands, wrists, and forefeet with respect to detection of progressive joint destruction in RA.

Free vascularized toe-joint transfer in hand reconstruction: a series of 25 patients.

Twenty-eight vascularized toe-joint transfers performed on 25 patients were reviewed. A number of different techniques were used: proximal interphalangeal joint or metacarpophalangeal joint reconstruction, one-stage double joint transfer, and interphalangeal thumb or trapezometacarpal joint replacement. Using these types of vascularized joint transfer allows one-stage composite transfer (including skin, bone, and extensor tendon) and provides rapid bone healing, potential growth in the young, good long-term cartilage preservation, normal lateral stability in pinch, and limited but useful range of motion (mainly at the proximal interphalangeal level).

Flow-through vascularized toe-joint transfer for reconstruction of segmental loss of an amputated finger.

A segmental finger defect was reconstructed in a 46-year-old woman with a free flow-through vascularized toe-joint, including the proximal interphalangeal joint, the plantar digital nerve, and tendons of the second toe. The advantages of this composite flap are: (1) The segmental loss of the finger can be easily reconstructed to achieve a normal anatomic structure. (2) Excellent cosmesis is achieved, compared with conventional flaps such as the groin flap. (3) The distal segment of the donor toe can be preserved. (4) The transected digital arteries of the amputated finger can be simultaneously reconstructed with a flow-through arterial interposition. (5) The digital nerve can be repaired with a vascularized plantar digital nerve graft.
