Proximal row carpectomy: an alternative to wrist fusion?

Problems with implant failure and silicone synovitis and a high complication rate in wrist arthrodesis have recently increased the interest in solutions that use residual biological articular surfaces. These include limited intercarpal fusions and proximal row carpectomy (PRC). PRC is a relatively easy procedure with few complications. We reviewed 27 personal cases. According to this study PRC offers a painless range of motion, with an average of 68 degrees flexion/extension range and an average grip strength of 60% of the contralateral side. The failure rate is 18.5%. However, failures can be successfully converted into wrist arthrodesis. Our follow-up period ranges from 6 to 36 months. Late deterioration has not been reported in the literature. On the contrary, improvement of mobility and grip strength several months after operation have been observed. We still favor PRC as a salvage procedure in order to offer the patient some motion, provided that there is no osteoarthritis over the capitate and the lunate facet preoperatively.

Psoas and adductor release in children with cerebral palsy.

In a retrospective study of 12 cerebral palsy patients with 17 hips treated for subluxation, clinical and radiographic results of psoas and adductor releases were reviewed. With an average follow-up of 4.05 years, the functional ability was improved in 3 spastic quadriplegics and 3 diplegics and maintained in 6 other patients. The CE-angle and femoral head coverage did not change significantly. The AC-index improved significantly (p = 0.01).

Wear of a titanium-alloy shoulder prosthetic head.

We present a case report of extensive wear that occurred on the surface of the titanium-alloy head of a shoulder prosthesis after only 2 years' service. Such wear warrants discontinuing the use of titanium-alloy articulating surfaces even in nonweight-bearing joints.

A new technique for the three-dimensional study of the spine in vitro and in vivo by using a motion-analysis system.

We introduce a new method with a motion-analysis system (MAS) to study the vertebral model in vitro. Compared with the currently most accurate technique, roentgen stereophotogrammetric analysis (RSA), the difference between the RSA and the MAS is 0.12 degree +/- 1.64 degrees. An accuracy with an error of 0.08 degree +/- 1.15 degrees is determined by means of an angle gauge. Although a significant difference between the MAS and the goniometer (p = 0.04) is found around the X-axis (theta; transverse plane), it is limited to < 1 degree. The MAS provides an in-depth insight into the mechanism of the three-dimensional rotation at each vertebra in vivo. The backward inclination of the apical vertebra (AV) and forward inclination of the upper-end vertebra (UEV) around the Y-axis (phi) results in a correction of the hypokyphosis shown by the Cobb angle in the sagittal plane. The clockwise rotation of the UEV in the Z-axis (psi) leads to a reduction of the Cobb angle in the frontal plane. Additionally, the MAS as an intraoperative alternative shows different results of the derotation maneuver by the Cotrel-Dubousset instrumentation (CDI) compared with the computed tomography (CT) scan. Our method gives more direct details of the derotation not influenced by patient posture, as observed in the CT scan.

Extensor indicis proprius to extensor pollicis longus transfer: results and complications.

In a detailed analysis of hand, thumb and index function after extensor indicis proprius transfer for extensor pollicis longus rupture in 13 patients, we found 12 excellent or good results despite mobility restriction in most of them. The extension lag in the metacarpophalangeal and interphalangeal joint of the thumb and the metacarpophalangeal joint of the index was respectively 17 degrees, 8.5 degrees, and 25 degrees. Extension force of the index was reduced to 65%. Grip force and dexterity reached 90% and 115% of the contralateral side.

Application of the IFSSH(3)-classification for congenital anomalies of the hand; results and problems.

The extended classification proposed by the IFSSH was used to classify 1013 hand anomalies in 925 hands of 650 patients. We found associated anomalies in 26.7%. The classification was straightforward in 86%, difficult in 6.6% and not possible in 7.8%. In group I the radial and ulnar deficiencies, limited to the hand and without forearm deficiencies should be included. Group II was the most important group including 513 anomalies. We propose to include in this group the Madelung deformity, the Kirner deformity and congenital trigger fingers and trigger thumbs. Triphalangeal thumbs are a problem, we suggest to list this anomaly in group III and to consider it as a duplication in length. It is not always possible to evaluate the (transverse) absence of the fingers or hand. Longitudinal deficiencies (group IIB), symbrachydactyly group (V) and amniotic bands (group VI) occasionally develop a phenotype similar to the genuine transverse deficiency (group IA).

Total knee arthroplasty in the young rheumatoid patient.

Thirty-four total knee arthroplasties were performed for severe rheumatoid arthritis in 25 patients younger than 45 years. All patients were available for follow-up evaluation at an average of 7.2 years. According to the Knee Society scoring system, the knee score improved from an average of 21 points preoperatively to 85 points at follow-up (p < 0.001). The average functional score improved from 23 points to 87 points (p < 0.001). Average range of motion improved from 71 degrees to 93 degrees (p < 0.001). Nonprogressive radiolucencies less than 1-mm thick were observed in 6 knees. One knee was revised for severe polyethylene wear; another case was revised for chronic patellar dislocation. Actuarial survivorship analysis estimates a 97% survivorship after 5 years and 90% after after 10 years. In young rheumatoid patients, total knee arthroplasty can therefore be considered as a reliable procedure, with satisfactory results during at least the first 5 to 10 postoperative years.

The sinus tarsi spacer in the operative treatment of flexible flat feet.

The results of operative treatment of 45 flexible flat feet (29 patients) using the sinus tarsi spacer are reported. Although radiological improvement in both the talar declination and the ground-navicular distance was found, our patients suffered from pain and functional impairment for an average period of 5 months. An unacceptably high rate of spacer dislocation was noted. Furthermore, the literature indicates spontaneous improvement as the natural history of flexible flat feet. We therefore no longer advise the sinus tarsi spacer as a routine treatment for flexible flat feet.

Congenital trigger digit.

For this study, cases involving 41 patients with 57 congenital trigger digit were reviewed. Two of these digits were seen when the patient was very young. However, most "congenital" trigger digits present sometime after the neonatal period. A clear difference exists between trigger thumbs and trigger fingers. In this series, thumbs were more frequently affected; 10 were bilateral, and none resolved spontaneously. Fingers were less frequently affected, and two of them recovered without operation. All 39 children had an operative release of the A1 pulley of the flexor tendon sheath, with excellent results.

The Ilizarov external fixator for treatment of deformities in Paget's disease.

Paget's disease of bone may cause progressive bowing of affected femurs and tibiae. Fractures or osteotomies in these patients technically are difficult to treat and may lead to delayed union or nonunion. The authors report their early results with the use of the Ilizarov external fixator to affix 3 corrective closing wedge osteotomies, 1 fracture, and 1 delayed union. Deformities were corrected fully during the surgery, with an option to correct remaining deformation progressively during the rest of treatment. Compression of the healing bone was applied to enhance osseous healing, when necessary. Three-dimensional control is possible, and the stability of the fixation is excellent in this structurally weak bone. Bony union was achieved without complications in all patients within 4 months.

Finger fractures in children treated with absorbable pins.

Biodegradable PDS-rods have been used for the treatment of phalangeal neck fractures to oppose the disadvantages and complications of K-wire fixation. Reduction can be maintained during fracture healing, and the surrounding joints can be mobilized early. Because of the recessed position of the rods, there is no interference with motion.
